2020-02-01T01:01:08 < invzim> meh, my enthisuasm for the rohm part quickly faded when I realized I had to make my own footprint from scratch
2020-02-01T01:01:22 < invzim> enthusiasm
2020-02-01T01:01:50 < aandrew> Making footprints isn’t a big deal
2020-02-01T01:02:34 < invzim> https://d1d2qsbl8m0m72.cloudfront.net/en/products/databook/datasheet/ic/power/switching_regulator/bd9f800mux-e.pdf
2020-02-01T01:02:37 < invzim> page 46
2020-02-01T01:03:40 < invzim> they actually don't even provide a recommended footprint
2020-02-01T01:05:27 < aandrew> That does not look bad at all
2020-02-01T01:06:06 < aandrew> Do they provide an STL or IGES? Using the model has revolutionized my PCB workflow
2020-02-01T01:06:17 < invzim> can't find anything
2020-02-01T01:06:32 < invzim> last 100+ parts I've just used the ipc wizard in altium
2020-02-01T01:06:33 < catphish> we've brexited
2020-02-01T01:06:53 < invzim> welcome to the world of gettig assraped by DHL and friends
2020-02-01T01:07:18 < Cracki> congratulations, you are no longer ruled by foreigners
2020-02-01T01:07:24 < Cracki> >_>
2020-02-01T01:07:56 < catphish> i already get assraped by DHL
2020-02-01T01:08:02 < aandrew> I hate Altium’s IPC Wizard
2020-02-01T01:08:17 < invzim> I think it's great
2020-02-01T01:08:24 < invzim> what's not to love?
2020-02-01T01:08:34 < aandrew> Waiting to see Britain reaping the rewards of such an idiotic move
2020-02-01T01:08:43 < aandrew> Ugly footprints mostly
2020-02-01T01:08:48 < englishman> found major HW bug today specifically because i pushed for an early prototype
2020-02-01T01:09:04 < englishman> if i hadn't have done that, we would not have found this bug until may-june
2020-02-01T01:09:13 < englishman> feels good to be right
2020-02-01T01:09:25 < englishman> fail fast
2020-02-01T01:09:46 < BrainDamage> invzim: at least for the pinout, you can try https://github.com/Robotips/uConfig
2020-02-01T01:10:08 < aandrew> invzim: http://rohmfs.rohm.com/en/techdata_basic/ic/package/htsop-j8_1-e.pdf
2020-02-01T01:10:11 < invzim> englishman: have some compliments :) https://www.youtube.com/watch?v=zi8ShAosqzI
2020-02-01T01:10:20 < BrainDamage> nvm, I saw the wacky footprint
2020-02-01T01:10:36 < aandrew> englishman: Good job
2020-02-01T01:10:42 < aandrew> What was the ugly bug
2020-02-01T01:11:03 < englishman> fucked up connector issue due to an ambiguous fucking shitty datasheet by a shit company
2020-02-01T01:11:14 < englishman> ty invzim
2020-02-01T01:11:49 < aandrew> Wtf, that doc isn’t for that footprint at all
2020-02-01T01:11:59 < invzim> I think the footprint is a ROHM exclusive for that part
2020-02-01T01:12:16 < aandrew> That is rohm’s document!
2020-02-01T01:12:32 < englishman> making footprints isn't a big deal
2020-02-01T01:12:34 < englishman> in fact
2020-02-01T01:12:40 < englishman> i'd say it's a no-compliments task
2020-02-01T01:12:44 < englishman> like obeying traffic rules
2020-02-01T01:13:06 < invzim> aandrew: thanks for link, but no "VQFN11X3535A" in it
2020-02-01T01:14:07 < englishman> can you just email rohm to get it
2020-02-01T01:14:43 < aandrew> Yeah I fucked it up.
2020-02-01T01:14:47 < invzim> yup, used their contact form
2020-02-01T01:14:54 < invzim> rohm=royal ohm, chinese company?
2020-02-01T01:16:47 < englishman> it's japiirc
2020-02-01T01:20:38 < invzim> allright, so no corona excuses then
2020-02-01T01:22:05 < BrainDamage> corona the beer excuses
2020-02-01T01:22:17 < invzim> ah, rohm is not royal ohm, but that one also exists http://www.royalohm.com/
2020-02-01T01:23:32 < englishman> that one is chinese
2020-02-01T01:24:44 < zapb_> Hey guys, this might be of interest to some of you: https://blog.zapb.de/stm32f1-announcement/
2020-02-01T01:25:23 < mawk> it's not the first to do this zapb_ 
2020-02-01T01:25:25 < mawk> but still cool
2020-02-01T01:26:14 < englishman> any more details
2020-02-01T01:26:28 < englishman> is it like the fraunhofer rdp2->rdp1 then timing thing
2020-02-01T01:26:41 < aandrew> I wonder if there are ways to physically damage the input buffers on SWDCK that aren’t risky to the rest of the chip
2020-02-01T01:32:51 < Cracki> uh
2020-02-01T01:33:17 < Cracki> wondering how they activate SWD when it's been deactivated
2020-02-01T01:35:02 < Steffanx> No thanks mawk 
2020-02-01T01:36:30 < Cracki> oh look, the author himself posted the link
2020-02-01T01:36:49 < Cracki> zapb_, got any idea if SWD function can be "burned out" safely?
2020-02-01T01:37:35 < Cracki> mawk, looks like they claim they can circumvent protection in all cases. I don't think that has been possible before.
2020-02-01T01:37:47 < Cracki> iirc the first level was downgradable but the second level wasn't?
2020-02-01T01:39:43 < Cracki> one guy, obermaier, shows up in both the fraunhofer thing and this one
2020-02-01T01:40:09 < Cracki> so let's assume he's aware of what he himself did previously.

2020-02-01T02:09:53 < qyx> meh
2020-02-01T02:10:30 < qyx> no info on the nCoV though
2020-02-01T02:11:37 < BrainDamage> it kinda sounds like a kernel feature

2020-02-01T03:34:22 < qyx> I'll just use a chinese spring antenna probably
2020-02-01T03:35:25 < englishman> cool
2020-02-01T03:35:32 < qyx> it should be located on the right side, there's a pad
2020-02-01T03:35:46 < Cracki> silicon chip soldered direclty, huh
2020-02-01T03:36:28 < qyx> what
2020-02-01T03:36:38 < englishman> missing some 3d models there
2020-02-01T03:36:57 < qyx> yeah, too lazy
2020-02-01T03:37:08 < Cracki> dude in the video says that, before he talks about the fractal antennae
2020-02-01T03:37:35 < Cracki> interesting, the squiggles might cancel each other out, which a spiral or zigzag wouldn't?
2020-02-01T03:38:18 < qyx> idk, I am tempted to randomly zig-zag a trace
2020-02-01T03:38:21 < qyx> and try
2020-02-01T03:39:46 < Cracki> simulate?
2020-02-01T03:40:37 < qyx> no, measure if I find someone with a proper tool

2020-02-01T04:28:00 < BrainDamage> the reason why fractal antennas are not popular is because when you account for manifacturer tolerances, etc their gain is marginal compared to more run off the mill antennas

2020-02-01T17:56:52 < jpa-> https://blog.zapb.de/stm32f1-announcement/    i'm surprised that someone bothers with responsible disclosure, isn't F1 protection pretty much broken anyway
2020-02-01T17:59:23 < Steffanx> What was broken before jpa-?
2020-02-01T17:59:25 < BillsBatVirus> and is it only f1?
2020-02-01T17:59:56 < Steffanx> They did F0 before, same guy.
2020-02-01T18:00:54 < jpa-> https://www.aisec.fraunhofer.de/en/FirmwareProtection.html  this was a few years before, and even before that chinese services offering readout of STM32F1 popped up

2020-02-01T18:09:53 < Steffanx> Luckily i dont give a damn about cryptocurrency  :P
2020-02-01T18:12:59 < BillsBatVirus> Steffanx: because during my proceedings, someone (highly likely it was Paul) was auto-botting the wiki for my name with "crimes" i was never charged with nor investigated for, and i had wikipedia blacklist me.
2020-02-01T18:13:23 < Steffanx> hah lol.
2020-02-01T18:13:55 < Steffanx> So there is a way to get of the internet? (or kinda)
2020-02-01T18:13:56 < BillsBatVirus> there are hilarious speculations on the ED page for me
2020-02-01T18:14:08 < specing> link
2020-02-01T18:14:12 < Steffanx> but it gets you on dramapedia instead.
2020-02-01T18:14:18 < Steffanx> not sure if that's a win.
2020-02-01T18:14:22 < BillsBatVirus> yeah but the wikipedia page was different.
2020-02-01T18:15:13 < BillsBatVirus> it was making statements of fact about my criminal case that weren't even part of the case. stating i had been charged with crimes that i was never actually charged with or even mentioned in any indictments against me.
2020-02-01T18:15:38 < BillsBatVirus> i contacted wikipedia about it and they refused to do anything
2020-02-01T18:15:42 < BillsBatVirus> then my lawyer got involved
2020-02-01T18:15:52 < BillsBatVirus> and they erased me from wikipedia permanently
2020-02-01T18:15:58 < jpa-> Steffanx: why need for more?
2020-02-01T18:16:35 < BillsBatVirus> i don't care about the ED page
2020-02-01T18:16:53 < BillsBatVirus> weev asked me back in 2010 if i wanted it removed and i said leave it
2020-02-01T18:18:48 < BillsBatVirus> it's never caused me any grief, and is for the lulz
2020-02-01T18:19:01 < BillsBatVirus> though if i ever wanted it ghosted, all i have to do is make a call
2020-02-01T18:19:49 < BillsBatVirus> (to some ED folks, just to be clear lol)
2020-02-01T18:34:21 < bitmask> haha this looks ridiculous: https://imgur.com/a/LrkR0V2  second image.  I decided to angle the transformer because the secondary cable isnt flexible enough and it lets the leads bend into place without stressing it
2020-02-01T18:34:27 < Steffanx> jpa-: I'm just asking what you meant by it was pretty much broken anyway 
2020-02-01T18:39:53 < englishman> jpa-: johannes obermaier is the author of both cves

2020-02-01T23:35:06 < zyp> and instead of relaxing while recovering like I guess most people would do, I went out and replaced the rear brake discs on my car today
2020-02-01T23:36:59 < zyp> had the car in for the biennial inspection yesterday, rear brake discs had too much rust
2020-02-01T23:37:21 < zyp> deadline was yesterday, so it's technically illegal to use the car now
2020-02-01T23:38:06 < Steffanx> Thats why i just have stuff like that done for me :P

2020-02-01T23:44:50 < qyx> wut aisler makes iban payments
2020-02-01T23:49:13 < BrainDamage> actually, that makes me think of a lucrative business, UV/autoclave sterilyzed for manifactured goods before shipping
2020-02-01T23:49:23 < BrainDamage> and UV treatment for packages
2020-02-01T23:49:30 < BrainDamage> tap into that global fear
2020-02-01T23:52:45 < zyp> Steffanx, yeah, roads are salted and also regenerative braking puts less wear on the discs, which means that rust won't get scrubbed so often

2020-02-01T23:59:34 < Cracki> but "makes" implies they're paying you...
--- Day changed Sun Feb 02 2020
2020-02-02T00:07:03 < qyx> they say you have to authorize them to "make a debit"

2020-02-02T00:07:14 < qyx> I have never seen such thing

2020-02-02T00:14:43 < Cracki> what's that called, sepa something
2020-02-02T00:15:05 < Cracki> nobody bothers with that unless it's for regular pulls
2020-02-02T00:15:23 < qyx> yeah sepa
2020-02-02T00:15:42 < qyx> actually it is good to have sepa, but in the classic way
2020-02-02T00:15:46 < Cracki> may be for time saving; once you give them auth, they can pull and concurrently start work. if you push money, they'll wait until it's confirmed.
2020-02-02T00:15:48 < qyx> they should make a proforma invoice
2020-02-02T00:15:50 < qyx> you pay it
2020-02-02T00:15:55 < BillsBatVirus> i wonder if there's any us based pcb fabs that aren't ridic expensive
2020-02-02T00:15:56 < qyx> and then they start manufacturing
2020-02-02T00:16:06 < qyx> Cracki: makes sense
2020-02-02T00:16:42 < BillsBatVirus> 4pcb.com doesn't list prices. that means $5000 per pcb
2020-02-02T00:17:15 < BillsBatVirus> osh park isn't too bad. will probably just go with them.
2020-02-02T00:17:28 < BillsBatVirus> if i have to pay $50 i guess that's better than waiting until 2025

2020-02-02T01:18:25 < zyp> egolf lets me choose how much to regen when I'm letting off the accelerator, from zero to almost full (and three steps in between)
2020-02-02T01:18:46 < zyp> switching between those with the shifter stick
2020-02-02T01:19:28 < zyp> generally drive with no regen while cruising and full regen for city driving
2020-02-02T01:19:46 < zyp> the latter means I can do most of the driving without even touching the brake pedal
2020-02-02T01:22:58 < qyx> and what does it do when you press the brake pedal?
2020-02-02T01:23:16 < qyx> does it do regenerative braking first?
2020-02-02T01:23:20 < zyp> yes
2020-02-02T01:29:14 < zyp> switching from cruising to full regen kinda feels like downshifting a manual car to engine brake harder
2020-02-02T01:29:26 < zyp> so my old habits translated well
2020-02-02T01:32:26 < qyx> I would feel uncomfortable with zero regen
2020-02-02T01:32:48 < qyx> even on highways
2020-02-02T01:33:45 < qyx> I would expect the car to slow down slightly with the accelerator released
2020-02-02T01:34:09 < zyp> well, it does, you're not driving in a frictionless vacuum
2020-02-02T01:34:56 < zyp> but yeah, one of my friends had the same reaction when he drove my car, he preferred the lightest nonzero mode
2020-02-02T01:36:55 < zyp> oh, and my wife too, but she doesn't really drive my car after she got her own
2020-02-02T01:37:34 < zyp> and her car only has one regen option
2020-02-02T01:38:15 < zyp> she's got the peugeot ion, which is a rebranded mitsubishi i-miev
2020-02-02T01:38:45 < zyp> IIRC the i-miev got a cruise and a stronger regen option as well, but they left that out from the peugeot
2020-02-02T01:38:45 < qyx> how much are EVs subsidized in .no?
2020-02-02T01:39:11 < zyp> much
2020-02-02T01:39:17 < specing> no VAT
2020-02-02T01:39:26 < specing> + high tax on ICEs
2020-02-02T01:39:28 < zyp> no VAT and no initial registration fee
2020-02-02T01:39:44 < qyx> so about 20% + ~500e?
2020-02-02T01:40:02 < zyp> no, the fee is a lot higher for most ICE cars
2020-02-02T01:40:17 < zyp> I think it's on the same order of magnitude as the VAT itself
2020-02-02T01:40:24 < qyx> uh
2020-02-02T01:41:00 < specing> isn't it 100%?
2020-02-02T01:41:02 < zyp> it's calculated from performance numbers, I don't remember exactly which at the moment
2020-02-02T01:41:13 < specing> When a 10keur ICE costs 40k eur?
2020-02-02T01:42:23 < zyp> hmm, it's based on weight and emissions now, I believe earlier it was based on power
2020-02-02T01:42:41 < qyx> here it is about 400e for a new  ~100kW ICE
2020-02-02T01:43:25 < qyx> for <80kW it is 66e :D
2020-02-02T01:43:53 < zyp> it's a progressive scale, here's some numbers: https://www.smartepenger.no/98-bil/354-engangsavgifter-pa-bil
2020-02-02T01:45:43 < qyx> offtopic, F722, there is a VREF+, but no VDDA
2020-02-02T01:45:50 < qyx> weird
2020-02-02T01:47:01 < Cracki> maybe different name
2020-02-02T01:47:14 < qyx> wait what, fuk kicad lib
2020-02-02T01:47:21 < zyp> haha
2020-02-02T01:47:27 < qyx> indeed it is VDDA on pin 13
2020-02-02T01:48:15 < qyx> also I hate power on top/bottom of the symbol
2020-02-02T01:48:17 < zyp> apart from those two exempts, there's also benefits from using an EV
2020-02-02T01:48:33 < qyx> can you drive in bus lanes?
2020-02-02T01:49:01 < qyx> ikea charging, etc? :D
2020-02-02T01:49:09 < zyp> one that's not really a benefit is that electricity is cheap in norway, so it costs about a fifth of what you'd pay for driving a comparable ICE car per km
2020-02-02T01:49:48 < zyp> and yeah, bus lane access, road toll exempts, ferry ticket exempts, but those are starting to go away
2020-02-02T01:50:07 < qyx> meh, we do not have enough free water to make an electricity
2020-02-02T01:50:26 < qyx> most of it comes from nuclear plants
2020-02-02T01:50:46 < qyx> but those bad, bad westeners do not like nuclear
2020-02-02T01:50:49 < zyp> also free parking
2020-02-02T01:51:05 < zyp> but that's mostly replaced with cheaper parking now
2020-02-02T01:51:59 < qyx> we are considering buying a hybrid or a phev
2020-02-02T01:52:19 < qyx> because not enough chargers on our usual routes
2020-02-02T01:52:36 < specing> qyx: can't charge @ home?
2020-02-02T01:52:53 < zyp> a couple of years ago I managed to get a ticket while I were in the courthouse getting married because I missed the change that EVs couldn't park for free outside anymore since two weeks earlier
2020-02-02T01:53:10 < qyx> specing: I live in a rented flat + building and offgrid home, so..
2020-02-02T01:53:28 < qyx> also it doesn't help until the range is less than about 300km
2020-02-02T01:53:36 < qyx> *is more than
2020-02-02T01:54:01 < zyp> the market leading cars now will easily do 300km
2020-02-02T01:55:07 < specing> qyx: so what? throw a wire through your window
2020-02-02T01:55:41 < zyp> specing, but what's the point?
2020-02-02T01:55:48 < specing> To charge it
2020-02-02T01:56:10 < qyx> haha
2020-02-02T01:57:49 < qyx> I can tow this https://i.pinimg.com/originals/03/69/cb/0369cb11a6a2bfb5b45fa7d7d3d41cf1.png
2020-02-02T01:57:51 < zyp> I mean, if you can't charge the EV easily at home and live somewhere without much other benefits for EVs, why buy one?
2020-02-02T01:59:03 < qyx> hece I said considering
2020-02-02T01:59:07 < qyx> *hence
2020-02-02T01:59:26 < qyx> now we have a nice classic 2.0L diesel
2020-02-02T02:12:23 < specing> yeah, no home charging is a deal breaker

2020-02-02T02:29:01 < zyp> well, if what we've got in norway this year can be called winter
2020-02-02T02:29:21 < zyp> temperatures were between +3C and -6C

2020-02-02T12:01:57 < zapb_> mawk, Cracki: this is about STM32F1, don't confuse this with F0. The F1 series has only a single protection level, similar to RDP 1 on the F0 series
2020-02-02T12:09:28 < zapb_> jpa-, Steffanx: the race condition of the F0 does not work on the F1
2020-02-02T12:10:07 < zapb_> Steffanx: I don't know if the SWD input buffers or something like this could be "safely" burned
2020-02-02T12:10:48 < jpa-> zapb_: oh, you are here :)
2020-02-02T12:10:58 < jpa-> indeed i misread the older one as F1 also
2020-02-02T12:11:39 < zapb_> yep, was offline couple of days. The disclosure process was stressful time ;)

2020-02-02T14:32:18 < zapb_> sync: what do you mean?
2020-02-02T14:32:48 < Steffanx> Why not publish it all now instead of somewhere in march is what he meant, zapb_
2020-02-02T14:33:20 < zapb_> Steffanx, sync: isn't that quite obvious?
2020-02-02T14:33:24 < Steffanx> It's not that ST can magically fix the issue..
2020-02-02T14:34:18 < Steffanx> or perhaps they can tell us how to blow the debug pins as a "fix".
2020-02-02T14:35:17 < BrainDamage> blowing the debug pins would be a much more robust way to fix many attack vectors
2020-02-02T14:35:30 < zapb_> Sure, however, there are still customers that might be able to fix / take appropriate action before we publish everything
2020-02-02T14:36:44 < zapb_> It would be a different thing if there would only a single customer we could inform directly
2020-02-02T14:40:14 < sync> no, not really
2020-02-02T14:41:09 < zapb_> sync: how familar are you with this topic?

2020-02-02T14:47:38 < sync> zapb_: I've had bad experiences before contacting vendors so now I don't bother anymore
2020-02-02T14:49:35 < zapb_> sync: note that I've talked about customers not vendors
2020-02-02T14:50:22 < zapb_> customers are affected by this vulnerability not only vendors
2020-02-02T14:50:56 < sync> sure, but that does not change anything
2020-02-02T14:51:33 < zapb_> sync: that's not correct IMO
2020-02-02T14:52:00 < Steffanx> I wonder if ST is going to make some public statement before the deadline.
2020-02-02T14:52:34 < Steffanx> I dont recall they ever mentioned something about the F0 stuff
2020-02-02T14:53:35 < sync> zapb_: nobody is going to change their product, even if so, if they are relying on the ROP to work on a non hardened cpu that's kind of their fault
2020-02-02T14:56:12 < zapb_> sync: cannot go into detail, sorry. But it makes a difference, at least for some customers
2020-02-02T14:56:56 < zapb_> Steffanx: I don't think so but we'll see :)
2020-02-02T14:58:42 < zapb_> sync: btw, with your experience, you won't be suprised about the disclosure timeline ;)
2020-02-02T15:00:33 < Steffanx> All those german hackers... :P
2020-02-02T15:06:53 < sync> zapb_: if you cannot go into detail it doesn't make a difference
2020-02-02T15:09:20 < sync> I mean, I can already get the ICs cloned so it's all kind of in vain
2020-02-02T15:11:16 < zapb_> sync: how do you clone these devices?
2020-02-02T15:23:01 < englishman> I'm a stm32 customer, can you disclose to me?
2020-02-02T15:24:26 < englishman> curious why you're treating this one differently from the f0 vulnerability?
2020-02-02T15:25:51 < zapb_> englishman: does not affect stm32 in general but stm32f1
2020-02-02T15:27:11 < englishman> ok, I buy stm32f1 as well
2020-02-02T15:30:40 < zapb_> englishman: if you rely on rdp you should assess what does this mean for your products and take appropriate action
2020-02-02T15:30:56 < englishman> so should anyone using rdp
2020-02-02T15:31:27 < zapb_> englishman: now more than ever, yes
2020-02-02T15:31:46 < englishman> sorry but I really don't understand this mentality
2020-02-02T15:32:17 < englishman> 12 years is a good run for RDP not being broken but flash can already be read out using other methods
2020-02-02T15:32:21 < sync> zapb_: send t hem to china
2020-02-02T15:32:47 < specing> stm probably already knows the method
2020-02-02T15:32:58 < specing> if china is offering it
2020-02-02T15:34:11 < zapb_> englishman: security is not about "if I can break something" but "what's the effort"
2020-02-02T15:34:39 < sync> the effort is putting it in an envelope
2020-02-02T15:35:34 < zapb_> sync: put your chips in an envelope then
2020-02-02T15:35:46 < zapb_> sync: not sure why you care at all and why you discuss
2020-02-02T15:36:19 < sync> because you feel like it make a difference to go through the hassle of contacting the vendor
2020-02-02T15:37:57 < zapb_> sync: never talked about vendors, read the backlog please
2020-02-02T15:38:52 < zapb_> specing: there is no single "magic method" to break a RDP
2020-02-02T15:39:21 < zapb_> specing: there a different depnding on your equipment, money and so on
2020-02-02T15:42:11 < specing> so there are multiple methods?

2020-02-02T15:43:15 < zapb_> specing: you should read about hardware security and the methods to attack an IC
2020-02-02T15:43:24 < zapb_> specing: then you know what I'm talking about
2020-02-02T15:43:42 < jpa-> what's the harm in responsible disclosure? it might not matter in the end, but it's not a bad idea, especially when the issue is not easy to fix
2020-02-02T15:44:02 < zapb_> what jpa- said.
2020-02-02T15:44:23 < zapb_> But I would call it "coordinated" ;)
2020-02-02T15:45:16 < jpa-> zapb_: so, is cracking stm32's your dayjob or do you do something else also? :)
2020-02-02T15:45:53 < zapb_> jpa-: I'm a contributor to OpenOCD, for example ;)
2020-02-02T15:46:14 < specing> It can't be a dayjob if he isn't being paid for it
2020-02-02T15:46:27 < jpa-> will we have "stm32f1.cpu flash unprotect noerase" in march?
2020-02-02T15:46:41 < specing> haha
2020-02-02T15:46:56 < jpa-> specing: wouldn't be too surprising if some security research company was employing stm32 hackers
2020-02-02T15:47:11 < specing> jpa-: yes, but they wouldn't be disclosing it
2020-02-02T15:47:20 < jpa-> maybe
2020-02-02T15:48:57 < zapb_> jpa-: this depends on the OpenOCD maintainers and if somebody implements it for OpenOCD ;)
2020-02-02T15:49:38 < specing> zapb_: didn't you just say that you are a contributor to it?
2020-02-02T15:52:17 < zapb_> specing: sure, but I don't waste my time implementing an exploit in OpenOCD ôO

2020-02-02T17:24:24 < Steffanx> Oh you mean those round dimmer remotes? 
2020-02-02T17:30:20 < specing> englishman: more or less, the runtime is GMGPL (afaik GPL with dynamic linking exception), so on embedded your program must be GMGPL-compatible

2020-02-02T17:32:36 < englishman> subscription only licenses are a hard no as are node locked

2020-02-02T17:36:39 < specing> englishman: why just to open the project? Can't you open the code in a normal text editor?
2020-02-02T17:37:09 < Steffanx> it works fine zyp. Although i only got it because it came with the bulb
2020-02-02T17:37:12 < englishman> specing: unfortunately with fpga code is only 1/2 of development
2020-02-02T17:37:15 < Steffanx> now its just an on-off switch.
2020-02-02T17:37:37 < specing> englishman: ah ok, I though aldec was a mcu devel env
2020-02-02T17:37:53 < englishman> no some gay paid ise alternative
2020-02-02T17:38:57 < specing> lol
2020-02-02T17:39:13 < zyp> so did icestorm revolutionize fpga development yet?
2020-02-02T17:39:42 < englishman> was looking at those lattice
2020-02-02T17:39:50 < englishman> they sure are small
2020-02-02T17:40:42 < englishman> but microsemi seems to pwn in the small cheap and actually useful FPGA space, if you have more than 1mm^2 board space
2020-02-02T17:41:38 < englishman> lattice also seems to make dev complicated but idk if opensores can help
2020-02-02T17:43:03 < specing> If its an ancient fpga project then it is probably possible to recreate it on modern mcus
2020-02-02T17:44:25 < englishman> 2012 was not that long ago
2020-02-02T17:44:45 < englishman> it's still lvds + ddr3 + usb3
2020-02-02T17:52:58 < Steffanx> So did you ever end up buying some panel switch thingy or .. what zyp?

2020-02-02T18:17:22 < aandrew> I found ice4/5 easy to dev. No nice hardware logic analyzer but simulation works just fine and is largely device independent
2020-02-02T18:17:44 < aandrew> MachXO2/3 was also pretty straightforward

2020-02-02T19:19:32 < Steffanx> Same here. Free shipping does not exist.
2020-02-02T19:20:19 < Steffanx> At least happened with DHL for me once. And when that happens they pick some overly expensive version of the shipping method. 
2020-02-02T19:23:46 < Steffanx> Cant you vote for iceland to get into the EU karlp?

2020-02-02T20:39:23 < kakiCoV> I know what those intel codes are but AMD no idea

2020-02-02T20:39:54 < Steffanx> Im glad you woke up, jadew.
2020-02-02T20:39:58 < kakiCoV> with AMD you can actually have high performance integrated graphics?
2020-02-02T20:40:18 < kakiCoV> in intel world you just pick cpu with latests intel UHD graphics
2020-02-02T20:40:34 < kakiCoV> it won't have performance but at least it has latest video accelerators
2020-02-02T20:41:03 < Steffanx> I've no clue about AMD. Last AMD i bought didnt come with integrated graphics and i just added an external gpu
2020-02-02T20:42:21 < kakiCoV> it was the time before AMD-ATI?
2020-02-02T20:42:33 < kakiCoV> and AMD APU
2020-02-02T20:42:40 < Steffanx> No it was very recent.
2020-02-02T20:42:54 < Steffanx> Ryzen 5 something
2020-02-02T20:45:06 < kakiCoV> last AMD I had was Athlon XP 2100+
2020-02-02T20:45:33 < kakiCoV> that is not very recent
2020-02-02T20:45:46 < kakiCoV> to say it's totally obsolete

2020-02-02T22:50:37 < kakiCoV> dirty_d: idk but sounds like the most likelly target
2020-02-02T22:51:41 < dirty_d> I can't get it to work. Also, I don't see how it should possibly work. They only have 64k flash, but the binary is larger than that
2020-02-02T22:52:11 < dirty_d> I hacked it to get the size down, but it still doesn't work for other unknown reasons

2020-02-02T22:58:27 < kakiCoV> I think I have heard this before
2020-02-02T22:58:51 < srk> it's complicated
2020-02-02T22:59:12 < kakiCoV> somebody was trying to squeeze black magic to some generic cheap stm32 platform
2020-02-02T22:59:13 < srk> there were versions under 64k before, I might have it branched somewhere
2020-02-02T22:59:25 < srk> some f103 are 128k afaik
2020-02-02T22:59:37 < srk> it's pretty common in chinese stlinks

2020-02-02T23:04:27 < srk> I'm now running G4 with blackmagic_stlinkv2 which uses stlink protocol
2020-02-02T23:05:34 < dirty_d> srk, that's what I've been building
2020-02-02T23:05:36 < srk> stlinkv3 on that board is F7 with no obvious SWD access
2020-02-02T23:05:47 < dirty_d> https://github.com/blacksphere/blackmagic/blob/master/src/platforms/swlink/README.md

2020-02-02T23:06:05 < srk> maybe via dfu but who cares if it works with hosted variant
2020-02-02T23:07:43 < dirty_d> I think I just have a STM32F103C8 that ireally is just 64k instead of 128k
2020-02-02T23:08:25 < dirty_d> I guess they're made with 128k, but that flash isn't verified to be working at the factory

2020-02-03T11:44:35 < mrec> I have set up a timer to sample falling and rising edges, that works fairly well. However if there's a glitch it might inject an unwanted sample. I'm reading 18 samples usually, I have a detection inside however it might require one additional read of 18 bytes until it's detected
2020-02-03T11:44:54 < mrec> is it possible to reset the sampling automatically in case only one sample arrived and the interrupt didn't get triggered?
2020-02-03T11:45:16 < mrec> eg. a timeout, all 18 samples have to be read within 30 milliseconds, if not everything arrives the dma should be reset

2020-02-03T11:50:52 < Cracki> your stm32 might have analog filtering on some pins for such situations
2020-02-03T12:01:01 < mrec> the glitches might come from the original machine I just don't trust the input
2020-02-03T12:01:29 < mrec> I'm working on a replacement for the Mechatronika feeder boxes
2020-02-03T12:02:05 < mrec> https://youtu.be/hXF81_SQXhA?t=15
2020-02-03T12:03:09 < mrec> the left boxes... last time one entire box jammed... after disassembling it I decided to add support for CL Feeders which just need to toggle a valve
2020-02-03T12:04:20 < mrec> the box is using one small stick to advance tapes, and everything's driven by 2 stepper motors. I always had issues with the accuracy.
2020-02-03T12:05:26 < mrec> so filtering is not really an option because the glitches might even come up during the actual command (I'm not really sure if there's a glitch but I'm better prepared for it)
2020-02-03T12:06:16 < mrec> sometimes when advancing a particular line, some other lane might also advance (that's either caused by a glitch or a bad firmware)
2020-02-03T12:06:28 < karlp> (re)start oneshot on every edge, if it expires, reset things.
2020-02-03T12:06:44 < karlp> turn it off cleanly in dma TC
2020-02-03T12:09:18 < karlp> that video is weird, is this some self devceloped one or is that "pro" gear? it's really hammering down on the board, you can see it get like a good 5-6mm deflectionat one point, easy.
2020-02-03T12:10:21 < mrec> it's a pick and place machine from poland really poor thing we bought it some years ago and only had trouble with it
2020-02-03T12:10:50 < mrec> I have already replaced the software which is already a great step forward, now we need to replace the feeders and the pick and place head....
2020-02-03T12:11:40 < mrec> and the cameras should also be replaced... the cvbs vision system is too slow

2020-02-03T12:12:19 < mrec> the software and gantry is waiting until the video is stable for the optical recognition; it all pushes the CPH down to 1.6k
2020-02-03T12:12:45 < mrec> and that company is dreaming of 3k cph .. well maybe without vision
2020-02-03T12:15:51 < karlp> what does that leave behind of the original machine?
2020-02-03T12:16:56 < mrec> the power supply.
2020-02-03T12:17:51 < karlp> hindsight would suggest you might havebeen better off buying a better mahcine :)
2020-02-03T12:17:58 < mrec> the portal is driven by a servo unit from Taiwan, they're pretty solid.
2020-02-03T12:18:27 < srk> mrec: running openpnp?
2020-02-03T12:19:00 < mrec> no, I wrote my own program for it.
2020-02-03T12:19:16 < srk> nice
2020-02-03T12:19:24 < srk> openpnp looks scary 
2020-02-03T12:20:22 < mrec> openpnp has some good ideas, but as usual nothing is perfect for everyone.
2020-02-03T12:20:50 < mrec> originally the pick and place machine always missed to pick up some components, we just recently figured out that all the feeders are unreliable for 0402
2020-02-03T12:21:19 < mrec> so there's a pick and place status in the list, if it cannot be picked we just skip it and mark it as not placed (that works okay)
2020-02-03T12:21:45 < mrec> initially the original software stopped the pick and place process, effectively bringing down the cph to around 500
2020-02-03T12:21:51 < srk> good ideas like what?
2020-02-03T12:21:52 < srk> haha
2020-02-03T12:22:09 < mrec> registering the pick and place status
2020-02-03T12:22:43 < mrec> I took that idea from openpnp, and added it into my application. Other than that I don't know much about openpnp to be honest
2020-02-03T12:22:43 < srk> sounds obvious :)

2020-02-03T22:14:10 < qyx> how, I2S -> codec -> amp?
2020-02-03T22:14:13 < Cracki> yes.
2020-02-03T22:14:18 < qyx> or just ADC -> amp?
2020-02-03T22:14:23 < Cracki> dac you mean
2020-02-03T22:14:31 < qyx> indeed, me dumb
2020-02-03T22:14:37 < Cracki> 12 bits then :P
2020-02-03T22:14:40 < Cracki> likely plenty
2020-02-03T22:14:51 < Cracki> 12 bits is around 60 dB range
2020-02-03T22:14:51 < qyx> it is for simple voice responses
2020-02-03T22:14:58 < Cracki> yeh dac + amp
2020-02-03T22:15:15 < qyx> I though using a codec would be overkill
2020-02-03T22:15:27 < Cracki> I was meaning to build a simple "signal generator" from an F3 and simple serial command line... same thing really.
2020-02-03T22:15:49 < qyx> yeah this is a HMI with RS485, LCD and a speaker
2020-02-03T22:15:58 < Cracki> yes codec is very fancy. prototype it. you'll see how well just dac + amp will perform.
2020-02-03T22:16:41 < qyx> I assume DMA'ing a ring buffer to a DAc is troublefree
2020-02-03T22:17:10 < Cracki> as trouble free as dma and interrupts can be :P
2020-02-03T22:17:54 < Cracki> haven't touched dac dma/interrupts yet. it likely has an interrupt on watermark.
2020-02-03T22:18:05 < qyx> if there was a aingle chip I2S codec with D-class stereo amp, I would consider it though
2020-02-03T22:18:57 < c10ud^^> some stmeval has it iirc
2020-02-03T22:19:32 < c10ud^^> old f401 maybe
2020-02-03T22:20:25 < emeryth> stm32 dac audio is perfectly fine
2020-02-03T22:21:55 < Cracki> my f3 dac has its own buffer. that introduces some clipping tho, so definitely disable that if it's going to an amplifier anyway
2020-02-03T22:23:46 < c10ud^^> probably the most effective way, prob  the eval codec is subsidized by st, when you buy it alone it might be costly

2020-02-03T23:35:27 < karlp> zyp: eh, just where I laid out these hub ports, 
2020-02-03T23:35:32 < karlp> tied myself in knots.
2020-02-03T23:41:41 < karlp> ok, swapped up and down, feasible at least.
2020-02-03T23:43:09 < zyp> remember that the hub lets you swap ports and polarity freely
2020-02-03T23:43:29 < karlp> oh, that's not normally been the issue
2020-02-03T23:43:51 < karlp> I just got all twisted with how I anted to have upstream, downstream and the "DUT" ports physically,
2020-02-03T23:44:05 < karlp> also, if I _don_t swap anything, I don't need to place and program an eeprom :)

2020-02-03T23:54:29 -!- c10ud^ [~c10ud@emesene/dictator/c10ud] has joined ##stm32
2020-02-03T23:54:39 < jadew> I wrote the SN on each board before baking them
2020-02-03T23:55:07 < jadew> but in the idea that it will come off during ultrasonic cleaning, I wrote it however I could, while the boards were in a pile
2020-02-03T23:55:17 < jadew> so the writing looked... ugly
2020-02-03T23:56:03 < jadew> well, it looks like this particular silkscreen melts slightly (changed color too) and the marker is now embedded in it
2020-02-03T23:56:49 < jadew> so I'm stuck with boards that have the SN written as if I was illiterate
2020-02-03T23:56:57 < Cracki> heh
2020-02-03T23:57:08 < Cracki> so you need to erase not just the marker but also the silkscreen?
2020-02-03T23:57:27 < jadew> I tried everything and just gave up on it
2020-02-03T23:57:31 < Cracki> you could paint on all the silkscreen, rebake to make silkscreen uniformly shit, then erase marker that's not on slik
2020-02-03T23:57:31 < jadew> I'm now putting a sticker on top
2020-02-03T23:57:34 < jadew> and writing on the sticker

2020-02-03T23:58:10 < Cracki> maybe get half a 3d printer and plot it next time :P
2020-02-03T23:58:58 < Cracki> does permanent marker get erased from ultrasonic bath?
2020-02-03T23:59:08 < jadew> it does
2020-02-03T23:59:08 < kakiCoV> my system has user generated by installer
2020-02-03T23:59:13 < jadew> as long as you don't bake them first
2020-02-03T23:59:17 < kakiCoV> *a user
2020-02-03T23:59:30 < Cracki> so... those pcbs have some coating that gets washed off, where the marker can't bond with anything permanent?
2020-02-03T23:59:46 < kakiCoV> how do I know if it's safe? I never set passwd for the user and it has it's own home directory

2020-02-04T00:00:35 < jadew> kakiCoV, is that user root?
2020-02-04T00:00:43 < jadew> :P
2020-02-04T00:00:52 < Cracki> didn't expect "installer" user on linux. i know some installer stuff on windows has its own account because SYSTEM seems unsuitable
2020-02-04T00:00:53 < emeb> karlp: heh - that PAM8301 mentioned in the zypsnips is kinda weaksauce. I've tried to use it to drive cheap 8ohm speakers and it distorts badly at any usable volume.

2020-02-04T00:08:53 < jadew> you can also do it via js
2020-02-04T00:09:21 < jadew> setTimeout(function() { window.reload(); }, time_in_ms);  // Maybe.

2020-02-04T00:49:45 < mawk> put this in <head>
2020-02-04T00:50:25 < kakihack> what is wrong with meta refresh?
2020-02-04T00:50:32 < mawk> old and ugly
2020-02-04T00:50:37 < mawk> but you can use it sure
2020-02-04T00:51:09 < mawk> and meta refresh has some bugs
2020-02-04T00:51:16 < mawk> if you refresh too fast the browser history doesn't work
2020-02-04T00:51:24 < mawk> hence the js that starts the refresh only after dom is loaded
2020-02-04T00:51:48 < mawk> you can use js to update only the bits of the page that changed
2020-02-04T00:52:09 < mawk> like have a server side endpoint that gives some html snippet for instance '<p>This is the dynamic data !</p>'
2020-02-04T00:54:42 < mawk> then you have for instance <div id="dynamic-data"></div> in the body, and in the setTimeout you can do fetch('/refresh-endpoint').then((response) => response.text()).then((text) => document.getElementById('dynamic-data').innerHTML = text);
2020-02-04T00:55:39 < mawk> as simple as that
2020-02-04T00:55:48 < mawk> and that <div> refreshes automatically without bothering the user
2020-02-04T00:57:30 < kakihack> what is dom?
2020-02-04T00:57:46 < kakihack> there is nothing dynamic thank god
2020-02-04T00:58:00 < mawk> then why do you want refresh if it's not dynamic
2020-02-04T00:58:04 < mawk> don't talk nonsense
2020-02-04T00:58:08 < mawk> if you want refresh it is dynamic
2020-02-04T00:58:11 < kakihack> because contents change
2020-02-04T00:58:16 < mawk> then it's dynamic
2020-02-04T00:58:28 < mawk> call it <div id="content-is-changing"> if you want
2020-02-04T00:58:30 < kakihack> it has zero client side functionality
2020-02-04T00:58:37 < mawk> yes it's okay
2020-02-04T00:58:41 < mawk> DOM is the html page
2020-02-04T00:58:50 < mawk> it's the name of the internal tree thingie representation

2020-02-04T01:02:00 < mawk> it's very easy
2020-02-04T01:02:04 < kakihack> what is dom
2020-02-04T01:02:32 < kakihack> I have heard of it
2020-02-04T01:02:35 < kakihack> DOM
2020-02-04T01:02:50 < kakihack> oh
2020-02-04T01:02:53 < kakihack> object model
2020-02-04T01:03:37 < kakihack> how does javascript refresh work if dom loading is stuck for some reason?
2020-02-04T01:03:51 < mawk> DOM is never stuck
2020-02-04T01:04:02 < mawk> also the DOMContentLoaded thing is only to *install* the handler
2020-02-04T01:04:10 < mawk> DOMContentLoaded is called when the html has finished loading
2020-02-04T01:04:15 < mawk> then the handler is installed, and it's good

2020-02-04T01:08:29 < kakinu> graphs
2020-02-04T01:09:40 < Cracki> great. if the browser flickers because it can't optimize the reload into a "change", you can think about reloading those pictures from javascript
2020-02-04T01:10:42 < Cracki> beware of caching.
2020-02-04T01:11:13 < mawk> you can bypass cache from js
2020-02-04T01:11:15 < mawk> using fetch
2020-02-04T01:11:25 < mawk> don't quit kakinu I'm doing the example for you
2020-02-04T01:11:27 < mawk> don't you dare

2020-02-04T01:12:04 < Cracki> that would be insecure :P
2020-02-04T01:12:21 < qyx> also kakinu, pls, there are graphing tools/libs/whatever readily available
2020-02-04T01:12:29 < qyx> are you reinventing something

2020-02-04T01:12:37 < kakinu> no
2020-02-04T01:12:47 < kakinu> graphs are graphing all the time

2020-02-04T01:17:41 < mawk> I have auto letsencrypt renewal
2020-02-04T01:17:45 < mawk> with DNS wildcard validation

2020-02-04T01:22:42 < Cracki> yes, LE is supposed to have autorenewal set up. still, ppl seem to fuck that up.
2020-02-04T01:23:01 < Cracki> use a script that sets things that get overwritten from elsewhere in the system or sth
2020-02-04T01:23:31 < Cracki> the conclusion being either a lot of people are _that_ dumb or linux is that much of a mess

2020-02-04T06:04:40 < dirty_d> yup, stm32g474
2020-02-04T06:05:22 < dirty_d> I guess technically it's possible that the i2c slave isnt working, but it was the last time I used it with an arduino
2020-02-04T06:06:37 < Laurenceb> there is a glitch before the main transaction
2020-02-04T06:06:41 < Laurenceb> might be causing issues
2020-02-04T06:07:49 < dirty_d> that was at 5V though, but this ic says its ok doen to 2.5
2020-02-04T06:07:52 < dirty_d> I saw that
2020-02-04T06:10:54 < dirty_d> The glitch happens when setting the pins to AF mode
2020-02-04T06:24:57 < dirty_d> I just tried it on the arduino, it worked
2020-02-04T06:25:15 < dirty_d> same signal, except it ACKed the arduino
2020-02-04T06:25:51 < dirty_d> so I guess that either means that glitch is screwing it up, or its not working on 3.3v
2020-02-04T06:26:37 < dirty_d> I can run the LCD on 5V since the signals are open drain right?

2020-02-04T15:22:21 < jpa-> so what are you changing between the working and non-working case? chip supply voltage, i2c voltage or both?

2020-02-04T15:23:25 < dirty_d> jpa-, working is an arduino, non working is stm32g4, 5v vs 3.3v
2020-02-04T15:23:30 < dirty_d> but the ic says 2.5v to 7v
2020-02-04T15:24:03 < dirty_d> i measured the vdd on the ic, it is 3.3v not being pulled low by the LCD or something
2020-02-04T15:27:04 < dirty_d> https://i.imgur.com/uXG1dCi.jpg
2020-02-04T15:28:18 < PaulFertser> Can it be powered by 5V but talked to using 3.3V from stm32?
2020-02-04T15:32:14 < Cracki> dirty_d, chip supply may not matter. check what both chips say I2C voltages have to be
2020-02-04T15:32:31 < Cracki> if you supply one with 5v and give it a 3.3v line...
2020-02-04T15:32:40 < jpa-> well, chip supply may affect the i2c voltages
2020-02-04T15:33:01 < PaulFertser> But stm32 is likely 5V tolerant on I2C pins.
2020-02-04T15:33:38 < Cracki> what Im getting at is that the slave chip might not detect level changes because the i2c bus runs at a lower voltage than itself. just a guess.
2020-02-04T15:33:39 < jpa-> and at that point it matters what voltage the pull-ups are connected to
2020-02-04T15:33:53 < Cracki> reproduce the arduino situation, LA it
2020-02-04T15:34:10 < jpa-> dirty_d: the classic case is to configure I2C pins on STM32 as "alternate push-pull" instead of "alternate open-drain" and then wonder why the slave cannot pull it down to ACK :P
2020-02-04T15:35:44 < jpa-> http://jpa.kapsi.fi/stuff/pix/i2c_levels.png   i can't remember how many times i've done three-level I2C like this by accident :P
2020-02-04T15:55:31 < aandrew> jpa-: looks like bus contention
2020-02-04T15:59:04 < jpa-> aandrew: yeah, what i wrote on the line above: forgetting to configure STM32 I2C pins as open-drain

2020-02-04T20:08:15 < kakihack> it's a bummer that the flash is not so8
2020-02-04T20:08:39 < kakihack> I would have soldered it off and read it for educational purposes
2020-02-04T20:13:57 < kakihack> pin 1 power, pin 2 has pull resistor and series resistor and pin 3 has series resistor and pin 4 is power

2020-02-04T20:44:07 < Laurenceb> like that black hole image paper
2020-02-04T20:44:32 < Laurenceb> where one guy on github did 99% of the work then some random uni grrrl was like "muh female empowerment"
2020-02-04T20:44:55 < Laurenceb> based git records
2020-02-04T20:45:49 < antto> is it okay if the names are kinda Slavic?
2020-02-04T20:46:43 < antto> to the unfamiliar they would all look "russian" ;P~
2020-02-04T20:49:16 < Laurenceb> heh I'll see how I get on thanks
2020-02-04T20:49:27 < Laurenceb> we tried to get NASA funding but didnt qualify
2020-02-04T20:50:01 < Laurenceb> so we wrote to the "program director" and he was really apologetic and basicallysaid we were rejected because they didnt know who we were lol
2020-02-04T20:50:24 < Laurenceb> so he has given us a list of people who might be interested in being authors

2020-02-04T22:22:48 < kakihack> Incorrect settings may lead to SRAM state retention loss over time and temperature. Thiscan cause erratic behavior due to SRAM data loss after wake-up from deep sleep mode orpower down mode

2020-02-04T22:26:19 < c10ud^> I tried reducing the sw to a simple hw bringup, setting frequency, rtos startup...then sdram_init and read at 0x28000000...everything good
2020-02-04T22:26:30 < c10ud^> 0x28D00000...hardfault
2020-02-04T22:27:04 < c10ud^> also it's funny because jlink can interact with the ram just fine.......

2020-02-04T22:34:09 < c10ud^> could this be that with no particular pressure the system still works but when going hard on ram it fucks up?

2020-02-04T22:41:13 < jadew> but it seems they force you to go through customs too
2020-02-04T22:41:15 < jadew> which is weird
2020-02-04T22:43:03 < Steffanx> Why is it weird?
2020-02-04T22:43:44 < jadew> Steffanx, I thought EEA meant they had the same benefits the other EU countries have for being in the EU
2020-02-04T22:44:03 < Steffanx> but that not being the case doesnt make it weird :P
2020-02-04T22:44:47 < jadew> it's not what I expected tbh
2020-02-04T22:44:57 < jadew> I thought EEA meant free trade
2020-02-04T22:45:04 < jadew> and free trade means no customs
2020-02-04T22:49:51 < karlp> well, it doesn't mean that.
2020-02-04T22:50:13 < karlp> free trade means whatever the framers of that version of the argument wanted it to mean, mostly, "someone gets to sell stuff they didn't used to"
2020-02-04T22:50:45 < karlp> within EU, you pay vat, sure, but that's it, EEA buying from EU gets vat exempt from EU, but then pays local vat.
2020-02-04T22:51:05 < karlp> (if they can convince the seller to give them a vat exempt price, otherwise, "just pay it twice!"
2020-02-04T22:52:03 < karlp> EEA largely means must accept most EP and EC rulings, but not allowed to vote on them. with a few exceptions. (fisheries being one of them)

2020-02-04T23:01:07 < jadew> karlp, customs are different tho, customs means it's not free trade
2020-02-04T23:01:20 < jadew> it's the same check that is performed if you sell to any country in the world
2020-02-04T23:01:32 < jadew> so where are the advantages?
2020-02-04T23:03:27 < jadew> I think it's illegal for a state within the EU to interfere with the sale of goods to another state in the EU, or to make it any more difficult than it is to sell within the same country
2020-02-04T23:03:51 < jadew> I thought EEA meant the same thing, but it seems it doesn't, and I'm no longer sure what it means
2020-02-04T23:04:47 < Cracki> >no customs
2020-02-04T23:05:06 < Cracki> it means same rules, generally
2020-02-04T23:06:01 < mawk> IE11 is 3% market share karlp , and anyway you have polyfills and shims

2020-02-04T23:12:07 < ColdKeyboard> Any suggestions for an IC that indicates when there is a 5V USB present and also indicates when current is being drawn? I see a lot of USB power switches with indication for fault but no if current is being drawn
2020-02-04T23:12:27 < Cracki> 128 MB over 115.2k will take 3 hours
2020-02-04T23:12:51 < mawk> you don't need an IC for measuring 5V presence ColdKeyboard 
2020-02-04T23:12:54 < Cracki> vbus present? connect to any gpio with a voltage divider maybe, or not if it's 5v tolerant
2020-02-04T23:13:19 < Cracki> consult your ref manual for whether your chip has a dedicated pin for that or whether you have to handle that yourself entirely
2020-02-04T23:13:37 < mawk> he can use a comparator opamp too
2020-02-04T23:13:40 < mawk> for precision
2020-02-04T23:13:44 < Cracki> chips also differ in whether they have an internal 1.5k pullup or whether that's your job too
2020-02-04T23:13:47 < mawk> and for the current any shunt will do
2020-02-04T23:13:56 < mawk> stm32 haz opamps
2020-02-04T23:13:57 < Cracki> 1.5k pullup must be controllable in case your're self powered
2020-02-04T23:14:19 < ColdKeyboard> I was wondering if anyone knows a USB Switch IC that also has this feature
2020-02-04T23:14:33 < ColdKeyboard> If not, I can build it with op-amp or a comparator but it would be awesome if it was all-in-one :)
2020-02-04T23:14:55 < Cracki> switch then, nothing particularly stm32? I was confused then
2020-02-04T23:15:25 < ColdKeyboard> My bad. I'm used to asking you guys electronics question as well as ask for help with STM32 :)

2020-02-05T00:25:24 < Cracki> it did that for me too because it prefers VP9 to h.264 these days. my hw is so old that it has to decode vp9 in software.
2020-02-05T00:25:39 < Cracki> they gain some bandwidth savings, I gain an electricity bill
2020-02-05T00:26:31 < Cracki> there's an addon to force h.264. that will limit you to at most fullhd video streams. they don't encode higher into h.264 anymore.

2020-02-05T00:28:30 < doomba> or just horizontally scaling 3-5A converters?

2020-02-05T00:29:11 < karlp> is this your off grid rockpi clustering, for doing off grid... off gridddy things?Ð
2020-02-05T00:29:17 < doomba> yea
2020-02-05T00:29:26 < karlp> personally I'd have smaller nodules of xV -> 5V close to each node
2020-02-05T00:29:39 < karlp> rather than dealing with sharing aroudn this massive 5V line.
2020-02-05T00:30:05 < doomba> makes sense. then i can just bulk order 12V->5V chinesiums
2020-02-05T00:30:11 < doomba> because they're like $5 each
2020-02-05T00:30:13 < karlp> indeed.
2020-02-05T00:30:33 < doomba> will also keep bom way less complicated
2020-02-05T00:30:47 < karlp> unless yhou'ðrebuilding thousands and getting really serious on the margins, that sort of building block is going to be cheaper/simpler.
2020-02-05T00:30:58 < karlp> says me, with no references.
2020-02-05T00:31:35 < doomba> i don't think an atx psu can handle that much current on the main atx connector
2020-02-05T00:31:46 < doomba> so what i was going to do is use 3 peripherals per stack of 4 rockpis
2020-02-05T00:32:05 < doomba> since psu i have is fully modular
2020-02-05T00:32:22 < doomba> and those peripheral connectors have 12V and 5V on them
2020-02-05T00:32:50 < doomba> so what i'm thinking now is to pull 12V from them and run that out to the little buck modules
2020-02-05T00:33:48 < doomba> that means i'd be able to have the atx plug in or plug in 12V
2020-02-05T00:33:52 < doomba> and the system won't care
2020-02-05T00:34:41 < doomba> actually it should be safe to just plug them both in at the same time
2020-02-05T00:37:43 < karlp> are you planning on usbing atx psus? that sounds needlessly complicated
2020-02-05T00:39:04 < zyp> karlp, didn't you decide on going the other way with your hubs?

2020-02-05T00:48:44 < karlp> well, it overlaps :)
2020-02-05T00:49:05 < karlp> I'm pyutting power switches and designing each individual board to be able to do 6x1A per port yes,
2020-02-05T00:49:22 < karlp> but I'd certainly never need it like that in my actual use case.
2020-02-05T00:50:04 < karlp> and I'll have the space for a reasonably modern 12/24v->5V buck as well, so will probably hve that as an option, which is still doing it locally and smaller

2020-02-05T01:28:54 < invzim> Also looking at Silergy SY8368, which I guess is more China friendly
2020-02-05T01:29:06 < invzim> although China is closed for the time being it seems
2020-02-05T01:29:43 < jadew> apparently shit is worse than they let it appear
2020-02-05T01:30:26 < invzim> it can probably be 10x worse, and stil milder than a normal flu
2020-02-05T01:30:34 < jadew> more reliable locations are reporting higher number of deaths per number of infected people
2020-02-05T01:31:49 < Cracki> the last handful of days of numbers out of china fit a *quadratic* equation nearly perfectly
2020-02-05T01:32:11 < jadew> invzim, check out that map, in Philippines there were two infected, one dead
2020-02-05T01:32:17 < Cracki> the one who found this thinks they're outright making up the numbers
2020-02-05T01:32:26 < jadew> yet, China, somehow manages to have 20k infected and only 400 deaths
2020-02-05T01:32:37 < qyx> worldometer reports 492 deaths to 876 recovered so far
2020-02-05T01:33:16 < Cracki> do you guys understand that it takes a while between infection, detection, and death/recovery?
2020-02-05T01:33:21 < qyx> yes
2020-02-05T01:33:23 < Cracki> i.e. deaths lag confirmed cases
2020-02-05T01:33:30 < Cracki> i.e. deaths/cases is a misleading number
2020-02-05T01:33:39 < qyx> I am comparing recovered true/false
2020-02-05T01:33:40 < Cracki> it's a gross underestimation
2020-02-05T01:33:45 < qyx> unrecovered means dead
2020-02-05T01:34:03 < qyx> ie. infected number is not telling anything
2020-02-05T01:34:10 < invzim> I still can't get myself to worry about it on a personal level
2020-02-05T01:34:17 < invzim> it's not like it's ebola
2020-02-05T01:34:19 < Cracki> case fatality rate is deaths/(deaths+recoveries), which is more unstable, but so far a lot closer to the truth
2020-02-05T01:34:30 < qyx> yeah
2020-02-05T01:34:38 < Cracki> ebola didn't spread as fast as this
2020-02-05T01:34:56 < jadew> yeah, this shit seems to be off the charts
2020-02-05T01:34:57 < qyx> so the question is if the spread is really that fast
2020-02-05T01:35:09 < Cracki> the only reason for you to relax is if your government does screening of travelers
2020-02-05T01:35:20 < invzim> my impression, totally subjective and unqualified, is that this it's like a flu and that old/sick people die from it
2020-02-05T01:35:39 < invzim> and of course, no vaccine so people at risk are really at risk
2020-02-05T01:35:39 < jadew> invzim, that's what my impression was too, but I'm not so sure anymore
2020-02-05T01:36:11 < invzim> Maybe I should watch some prepper videos :)
2020-02-05T01:36:28 < Cracki> likely yes, it's been 2/3 men and those are mostly elderly
2020-02-05T01:36:40 < invzim> Seems I need an AR15 and 10k rounds of ammo
2020-02-05T01:36:41 < Cracki> watch prepper videos regardless :P
2020-02-05T01:36:47 < Cracki> this won't be the last loose bioweapon
2020-02-05T01:37:03 < jadew> right, I was thinking the same, even if this gets stopped
2020-02-05T01:37:21 < jadew> considering how much we're moving, it's likely that we'll have something that won't get stopped, in our lifetimes
2020-02-05T01:37:22 < Cracki> an ar15 won't keep you alive from this, but it will keep you alive from rabid city dwellers
2020-02-05T01:37:29 < jadew> so it's probably worth being prepared in some way

2020-02-05T01:39:31 < jadew> saw some FFP2 at the hardware store
2020-02-05T01:39:35 < Cracki> n95 only says 95% of air gets filtered, but that still gets you killed
2020-02-05T01:39:44 < Cracki> you need 100% filtered, down to whatever size that virus is

2020-02-05T01:40:00 < jadew> well, the point is so you don't get droplets in
2020-02-05T01:40:04 < qyx> hah
2020-02-05T01:40:06 < jadew> you won't get the virus by itself
2020-02-05T01:40:14 < Cracki> hm right, droplets are the problem
2020-02-05T01:40:36 < doomba> eventually you're gonna have to go to walmart to receive your china rations and that's when you'll contract it.
2020-02-05T01:40:37 < Cracki> qyx, yeah when you start from the 27th or so, it's a chi squared of 1.000
2020-02-05T01:40:40 < Cracki> 1.0000
2020-02-05T01:41:10 < Cracki> this should be following an exponential growth, shouldn't it? what possible excuse could it have to spread quadratically
2020-02-05T01:41:40 < Cracki> that's like something random in nature suddenly having uniform distribution (rectangle) instead of gaussian
2020-02-05T01:42:33 < qyx> yeah I would say exponential with some margin, but I don't quite understand why it is wuadratic
2020-02-05T01:42:57 < Cracki> heh, they must have heard the dude caling them out, and gave today's number a bit more noise
2020-02-05T01:43:13 < doomba> what i wanna know is why is it infecting so many chinese people
2020-02-05T01:43:15 < Cracki> it's quadratic because cooked
2020-02-05T01:43:20 < Cracki> as cooked as a BAT
2020-02-05T01:43:29 < Cracki> duh because it started there :>
2020-02-05T01:43:29 < qyx> cooked bat is good bat
2020-02-05T01:43:41 < Cracki> uncooked bat causes cooked people
2020-02-05T01:43:43 < qyx> uncooked one is is a bad bat
2020-02-05T01:44:39 < Cracki> this is bat country
2020-02-05T01:44:45 < doomba> you would think it would be infecting mexicans mainly because it is coronavirus afterall
2020-02-05T01:45:01 < Cracki> har
2020-02-05T01:45:26 < Cracki> shit's sold out around here. either a lot more memesters than I think or it's just that cheap
2020-02-05T01:45:31 < jadew> the 2/3 men ratio is weird - why is that happening
2020-02-05T01:45:33 < jadew> ?
2020-02-05T01:45:41 < Cracki> patriarchy
2020-02-05T01:45:49 < Cracki> oh wait, they're communists, women go to work too
2020-02-05T01:46:40 < Cracki> some say it's because of physical exertion, maybe more breathing at work, who knows
2020-02-05T01:46:48 < doomba> jadew: something about the virus does something with some receptor in the brain that controls blood pressure in males but not females - so it's more lethal in men is what i heard.
2020-02-05T01:46:51 < Cracki> maybe it targets male biology
2020-02-05T01:47:11 < jadew> well shit...
2020-02-05T01:47:26 < doomba> so you could get hypotension or w/e and with the constant coughing, you pass out.
2020-02-05T01:47:29 < Cracki> that strain has parts of HIV in it. some indian scientists called that "fortuitious" (no chance it's natural)
2020-02-05T01:47:43 < Cracki> blood pressure?
2020-02-05T01:48:05 < Cracki> how do ncov patients die anyway, I thought it's diminished lung function among other things?
2020-02-05T01:48:05 < doomba> good thing i'm really fat and i smoke cigarettes, so if i get the virus i can just scale back on my blood pressure medication to balance it out.
2020-02-05T01:48:15 < kakihack> https://openipc.org/ I think I could work with this
2020-02-05T01:48:26 < Cracki> camera
2020-02-05T01:48:29 < Cracki> wat for
2020-02-05T01:48:37 < jadew> Cracki, me too, but apparently they die from a multitude of reasons
2020-02-05T01:48:45 < kakihack> for doing camera stuff
2020-02-05T01:48:45 < jadew> multiple organs failing for example
2020-02-05T01:49:22 < jadew> there's very little info on what it does
2020-02-05T01:49:26 < Cracki> reading https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(20)30211-7/fulltext
2020-02-05T01:49:28 < jadew> even tho they have plenty of evidence there
2020-02-05T01:50:10 < Cracki> so basically pneumonia. I wonder what else follows naturally from diminished lung function, and what is unique to ncov
2020-02-05T01:50:18 < doomba> Cracki: the paper by the indians about the strain having parts of HIV was released to a medium that does zero peer reviews - thus it's not peer reviewed. and the method of study was NIH's BLAST tool, which is a complete crapshoot. you can put any random sequence into that tool and link literally any virus to HIV with better probability than nCoV
2020-02-05T01:50:34 < Cracki> lol
2020-02-05T01:50:46 < Cracki> ok, tell me, any peer reviews on it yet?
2020-02-05T01:50:59 < doomba> no. it's essentially pseudoscience
2020-02-05T01:51:17 < Cracki> the fact that it isn't peer-reviewed doesn't disprove anything, it just makes clear that they could be making shit up
2020-02-05T01:51:36 < qyx> https://www.reddit.com/r/dataisbeautiful/comments/eyq00a/oc_too_good_to_be_true_quadratic_function_vs/
2020-02-05T01:51:39 < qyx> wtf is she saying
2020-02-05T01:51:47 < qyx> The limiting factor for confirmed cases are the test materials. Because there is a constant amount of test materials able to be used each day, the number of confirmed cases is increasing linearly, and the reports show a quadratic function. But it's not reality
2020-02-05T01:51:50 < Cracki> I was excited for the indians... guess they can't into space and they can't into microbiology either
2020-02-05T01:51:59 < doomba> i think the reason behind them doing the "study" and releasing that paper was to try to entice people possibly more "in the know" into doing more investigation into the virus's origin to find out if china is being forthcoming
2020-02-05T01:52:33 < Cracki> roughly constant testing capacity would restrict you to linear growth
2020-02-05T01:52:46 < doomba> mainly because there are too many coincidences that give rise to the various conspiracy theories surrounding this
2020-02-05T01:52:58 < Cracki> so to get quadratic growth, you'd need linear CAPACITY to MAKE testing equipment
2020-02-05T01:53:40 < qyx> so increasing the amount of testing material available linearly every day
2020-02-05T01:54:04 < Cracki> I'm sure they can scale up materials simply, but they need apparatus too
2020-02-05T01:54:58 < Cracki> and that SusanForeman doesn't explain quadratic growth, only linear growth
2020-02-05T01:55:22 < doomba> i mean come on. the ONLY BSL-4 that studies BAT SARS is 30 miles away from Ching Chong's Wuhan Bat Soup Bazaar. the logo is the SAME logo of umbrella corp from resident evil. gates foundation holds a patent on the fucking thing. 3 months before outbreak, gates foundation holds Event 201 - a mock pandemic event caused by a CORONAVIRUS. and gates is on record implying that the only way to save the
2020-02-05T01:55:24 < doomba> planet from climate change is for a global pandemic to reduce the population.
2020-02-05T01:55:55 < qyx> haha
2020-02-05T01:56:11 < Cracki> that umbrella corp knockoff isn't actually in china
2020-02-05T01:56:15 < Cracki> but it's real
2020-02-05T01:56:21 < doomba> yea
2020-02-05T01:56:31 < Cracki> they do have a biolab near that ground zero
2020-02-05T01:56:40 < Cracki> they claim it's not for bioweapons, but for research
2020-02-05T01:56:52 < Cracki> still, something could have tipped over and escaped
2020-02-05T01:57:07 < Cracki> the gates foundation thing is suspicious though
2020-02-05T01:57:08 < doomba> however. i think if a major outbreak occurs in the next few weeks in western countries, you're gonna see censorship by bigtech like we've never seen before to get a lid on these very strong coincidences and the tin foil conspiracies they've spawned.

2020-02-05T01:57:31 < Cracki> tho coronavirus is a huge class, it includes SARS and a few other celebrities
2020-02-05T01:57:36 < doomba> because when people are starving because they're on martial law lockdown, they're gonna start giving into said theories as fact. and that means civil unrest and lots of chaos.
2020-02-05T01:58:23 < Cracki> the biggest problem I see rn is that we have regular flu season in most places, so more ppl will have *some* symptoms and want to get checked
2020-02-05T01:59:05 < doomba> and going to hospitals just to get checked is the worse thing they can do
2020-02-05T01:59:12 < Cracki> otoh this could give ppl an excuse to lie to themselves and say it's just the flu while they're dying
2020-02-05T01:59:16 < Cracki> heh
2020-02-05T01:59:34 < doomba> if it's just the flu, they just met up with 500 other people who think they have coronavirus... and all it takes is 1 of those people to actually have the virus and doublefuck the rest of em.
2020-02-05T02:00:22 < doomba> here in the good ole USA where we have no health insurance and if you're poor just die

2020-02-05T02:01:05 < Cracki> the squared coefficient I've seen estimated as 120-180
2020-02-05T02:01:09 < doomba> if i can't breathe, hospital time. they can't refuse you if it's an emergency.
2020-02-05T02:01:13 < Cracki> so they can add 120-180 testing capacity per day
2020-02-05T02:01:29 < Cracki> still, those numbers are too smooth for reality

2020-02-05T02:02:22 < doomba> maybe it was coronavirus.
2020-02-05T02:02:40 < doomba> i talk so much shit about bill gates and eugenics on IRC - maybe they tested it on me first.

2020-02-05T02:04:06 < doomba> there's nothing you're gonna do to stop it or prevent yourself from getting it aside from moving away from civilization and then i'd say it's still a 50/50 because we don't know how it spreads fully.
2020-02-05T02:04:24 < Cracki> my god half the reddit comments are total smoothbrains
2020-02-05T02:05:12 < Cracki> neckbeards arguing that this type of fit can't be used because it has a left arm... while ignoring the point that the data FIT very well, from a certain date onwards
2020-02-05T02:05:19 < doomba> even if you're 100 miles from another human, you could still possibly get infected because of birds and mosquittos and other animals i would reckon
2020-02-05T02:05:25 < Cracki> nah
2020-02-05T02:05:35 < Cracki> diseases don't often jump species
2020-02-05T02:05:48 < doomba> they can carry it though

2020-02-05T02:09:17 < kakinu> question is who will survive
2020-02-05T02:09:21 < Cracki> it will, it's german engineering
2020-02-05T02:09:33 < jadew> kakinu, the women
2020-02-05T02:09:33 < Cracki> even the china clones, because they're faithful copies

2020-02-05T02:10:19 < kakinu> they say that it's targeted to males to correct some inbalances in region
2020-02-05T02:10:25 < jadew> if this is the pandemic that will thin the herd, it pays to survive it if you're a guy
2020-02-05T02:10:35 < jadew> there will be twice as many women
2020-02-05T02:11:05 < Cracki> imbalance is right. china has an at-birth ratio of 1.15 male:female
2020-02-05T02:11:09 < Cracki> https://en.wikipedia.org/wiki/List_of_countries_by_sex_ratio
2020-02-05T02:11:10 < kakinu> in china male/female ratio is huge social issue
2020-02-05T02:11:29 < Cracki> and they have no way to kill them off in wars
2020-02-05T02:11:33 < doomba> jadew: ya but if you manage to survive it but you are against proprietary centralized platforms and surveillance capitalism, they'll just kill you at the end.

2020-02-05T02:12:49 < doomba> lol i am. i'm the person the virus is intended to wipe out
2020-02-05T02:14:04 < doomba> they don't just wanna thin the herd. they want to diverge humanity into two distinct genetically differing subsets - like the eloi and morlocks

2020-02-05T02:15:18 < Cracki> ^
2020-02-05T02:15:21 < jadew> seems to me they want to mix us back

2020-02-05T02:15:38 < dirty_d> hmm, my sysclk is 170MHz, but delay_cycles(170) is taking 8.125us https://pastebin.com/VAVxP57m
2020-02-05T02:15:38 < doomba> nah this is different than an ethnicity mix
2020-02-05T02:15:47 < Cracki> 170 mhz, that's odd

2020-02-05T02:17:37 < dirty_d> Cracki, the systick regs dont let you use any clock other than the system clock
2020-02-05T02:17:58 < doomba> they're all more or less similar genetics, unlike countries like USA and soon EU.

2020-02-05T02:18:05 < jadew> that means that if we're all homogenuous, then we have less of a chance to survive a pandemic
2020-02-05T02:18:35 < jadew> if everyone has the same mix, it's not diverse anymore
2020-02-05T02:18:37 < jadew> it's the same shit
2020-02-05T02:18:52 < doomba> yeah but that's not exactly how the mixing works lol
2020-02-05T02:18:57 < dirty_d> Cracki, oh wait, actually it does let you specify a different clock
2020-02-05T02:19:04 < jadew> doomba, it is, over time
2020-02-05T02:19:11 < Cracki> dirty_d, also make sure you're using those systick registers right.
2020-02-05T02:19:12 < doomba> jadew: yeah a LOOOOOONG time. millions of years.

2020-02-05T02:19:37 < jadew> doomba, probably several hundreds of years
2020-02-05T02:20:26 < doomba> jadew: the only way for it to be that mixed in 100 years is by force. and even then it's simply infeasible to mix the gene pool with every possible ethnicity.
2020-02-05T02:20:40 < jadew> not 100 years, but several hundreds, very possible
2020-02-05T02:20:57 < jadew> there aren't that many variations of humans
2020-02-05T02:20:59 < dirty_d> Cracki, yea I set the right clock source and now it's 1.083us. Order is restored
2020-02-05T02:21:07 < doomba> that would mean the powers that be need to maintain accelerating forced mixing like they're doing in EU. it's simply not sustainable.
2020-02-05T02:21:18 < Cracki> good good
2020-02-05T02:21:48 < dirty_d> I was looking at the cortex-m0 reference before and you can't change the systick clock source to anything except the system clock on that, on m4, its the external clock my default
2020-02-05T02:22:59 < Cracki> doomba, natural mixing and natural divergence are in a balance with each other. they settle into what we had maybe 100 years ago
2020-02-05T02:23:55 < doomba> Cracki: i think EU is trying to accelerate it for reasons unknown. imo it should be left to naturally occur.
2020-02-05T02:24:06 < Cracki> dirty_d, what clock did you have when it was wrong? something around 20 MHz?
2020-02-05T02:24:18 < Cracki> they're not doing that to everyone
2020-02-05T02:24:42 < dirty_d> Cracki, that's what I calculated 20MHz

2020-02-05T02:24:53 < Cracki> but what clock source would that be
2020-02-05T02:25:07 < Cracki> you said you found out it was configured wrong, what was it using before

2020-02-05T02:30:07 < jadew> hah! I broke into one of those too
2020-02-05T02:30:14 < jadew> but it was for a project
2020-02-05T02:30:22 < jadew> was supposed to extract video from it
2020-02-05T02:30:38 < jadew> telnet was already on
2020-02-05T02:31:05 < Cracki> dun dun dun
2020-02-05T02:31:26 < jadew> actually, I'm not sure it was the same thing
2020-02-05T02:31:56 < Cracki> if it's anything from hisilicon, I'd bet it has a backdoor now
2020-02-05T02:32:02 < jadew> I scanned the article and thought they're only used in DVRs
2020-02-05T02:32:42 < jadew> well, that backdoor looks intentional
2020-02-05T02:33:20 < jadew> the device I managed to broke into (a DVR) had the same root password across all of them
2020-02-05T02:33:31 < jadew> and it was something like 123321
2020-02-05T02:33:41 < jadew> *break
2020-02-05T02:34:12 < jadew> getting the video out was not that easy tho

2020-02-05T02:34:26 < jadew> it didn't use a normal file system
2020-02-05T02:35:19 < Cracki> oh, of that ncov study of 99 patients, 50! had chronic diseases already, so fated to die
2020-02-05T02:35:27 < jadew> all the hdd was made up of chunks of files and each chunk was pointing to the next chunk
2020-02-05T02:35:49 < Cracki> linked list strewn across block storage?
2020-02-05T02:35:55 < jadew> yep
2020-02-05T02:35:56 < Cracki> was it an actual hdd?
2020-02-05T02:36:01 < jadew> yeah
2020-02-05T02:36:28 < Cracki> ze fuk, why, they could have used anything, fat32, some ext, anything!
2020-02-05T02:36:45 < jadew> I don't know
2020-02-05T02:36:52 < Cracki> so what did you end up doing, dump whole disk and reassemble off-device?
2020-02-05T02:37:22 < Cracki> maybe those "SoCs" are so weak they couldn't afford a proper file system
2020-02-05T02:37:37 < Cracki> even arduino can read fat from an sd card...
2020-02-05T02:37:43 < jadew> no, I wrote a program that was able to read that stuff and only pass on some of the frames
2020-02-05T02:37:50 < jadew> cross compiled it and then ran it from the DVR itself
2020-02-05T02:38:30 < jadew> the project was scraped, because I realized I was going to put a lot more work into it for little return
2020-02-05T02:38:51 < jadew> and the other guy was going to run the business side of things, and didn't like that
2020-02-05T02:39:15 < jadew> Steve Jobs - Wozniak kind of a deal
2020-02-05T02:41:59 < Cracki> wat was the business idea behind entering a DVR through a backdoor and reassembling its disk structure?
2020-02-05T02:42:19 < jadew> can't tell you...
2020-02-05T02:42:25 < Cracki> maybe not data recovery
2020-02-05T02:42:27 < jadew> it wasn't mine to begin with
2020-02-05T02:42:30 < jadew> no
2020-02-05T02:42:37 < jadew> it was a computer vision thing
2020-02-05T02:42:38 < Cracki> sounds like espionage :P
2020-02-05T02:42:41 < Cracki> lol
2020-02-05T02:43:04 < jadew> I mean the data would have been processed afterwards
2020-02-05T02:43:17 < jadew> but it had to be taken out somehow
2020-02-05T02:43:19 < Cracki> am I right in assuming those things have no (suitable) way to get a video feed out of them?
2020-02-05T02:43:30 < jadew> correct
2020-02-05T02:43:34 < Cracki> kek
2020-02-05T02:43:53 < jadew> that's what I was working on (and succeeded)
2020-02-05T02:44:33 < kakinu> dvr doesn't have a way to get video out?
2020-02-05T02:44:36 < Cracki> reminds me of that time some indian showed up in another channel, said he wanted to use tens of thousands of cameras from indian grocery stores to estimate on-display stock situation
2020-02-05T02:44:51 < jadew> kakinu, you can get it out, via the web interface, but it's a shitty way of doing it
2020-02-05T02:44:57 < jadew> and you have to get everything
2020-02-05T02:45:08 < kakinu> web video player?
2020-02-05T02:45:09 < Cracki> all I could advise him is to give up because he ain't gonna structure that kind of environment into anyhting usable
2020-02-05T02:45:11 < jadew> we needed to make it fast to download a full day of video
2020-02-05T02:45:15 < jadew> from thousands of customers
2020-02-05T02:45:36 < Cracki> web interface isn't fast to download?
2020-02-05T02:46:06 < jadew> Cracki, I did that math, it was not going to be fast enough
2020-02-05T02:46:10 < Cracki> ah so you weren't interested in live streams, but maybe a reduced daily set (1 fps or sth)
2020-02-05T02:46:16 < jadew> yeah
2020-02-05T02:46:30 < jadew> it all had to be downloaded at some point in the day and then processed
2020-02-05T02:49:01 < Cracki> >11 (11%) patients [...] died of multiple organ failure.
2020-02-05T02:49:33 < Cracki> sounds like you might have had some fun just replacing large parts of that DVRs firmware
2020-02-05T02:49:53 < Cracki> i.e. whatever receives video through whatever ports, so you get that directly and do whatever with it

2020-02-05T02:50:06 < jadew> well, the DVR had to keep its functionality
2020-02-05T02:50:11 < Cracki> boo
2020-02-05T02:50:25 < jadew> I was just piggybacking
2020-02-05T02:50:40 < Cracki> how much data per day did they make?
2020-02-05T02:50:52 < Cracki> and how much would you have needed?
2020-02-05T02:52:22 < jadew> I don't remember the exact numbers...
2020-02-05T02:52:52 < jadew> I just know it would have been enough that even Romanian internet wouldn't have been enough
2020-02-05T02:53:27 < jadew> also, the download speed was not the only issue
2020-02-05T02:53:31 < jadew> processing time was a problem too
2020-02-05T02:53:43 < jadew> so reduced frame rate would have helped in that regard too
2020-02-05T02:53:47 < kakinu> Cracki: multiple organ failure = suffocation?
2020-02-05T02:54:59 < Cracki> those dvrs might store as jpeg/mjpeg, then you could grab any subset of frames you want. even with keyframed codecs that's an option, but not as simple
2020-02-05T02:55:40 < jadew> it was H.264
2020-02-05T02:55:57 < Cracki> I would assume not, suffocation would be just that, more must have been failing

2020-02-05T04:18:28 < Cracki> but this also indicates that they're limited in how much testing capacity they can add every day
2020-02-05T04:18:40 < Cracki> if they had constant testing capacity, the trend would be linear
2020-02-05T04:19:06 < Cracki> and that is also assuming they don't just cook the numbers outright

2020-02-05T06:37:29 < Cracki> for one, you can have a debugger attached, keep ram contents, and reset
2020-02-05T06:37:42 < Cracki> i.e. write code to ram and have that executed
2020-02-05T06:38:27 < dirty_d> oh ok that makes sense

2020-02-05T06:38:42 < Cracki> if your code fits in ram, it spares you from reprogramming flash too...
2020-02-05T06:39:01 < Cracki> but reprogramming flash is only slow with shit debuggers. segger jlinks are very fast with that
2020-02-05T06:39:16 < Cracki> (and they try to rewrite only what changed)

2020-02-05T06:40:59 < Cracki> a debugger can reset target and have it boot from ram regardless of boot0/1 state... I think
2020-02-05T06:41:09 < Cracki> lots of people wonder what boot from ram is actually good for
2020-02-05T06:42:32 < dirty_d> can it?

2020-02-05T06:43:16 < dirty_d> it would seem if the debugger could do that, there would be no point in forcing boot to ram since a debugger is the only thing you'd be doing that for?

2020-02-05T06:44:26 < Cracki> some chips have at least one boot bit in option bytes, so programmable instead of external
2020-02-05T06:44:44 -!- ub|k [~ubikuitou@indico/developer/ubik] has joined ##stm32
2020-02-05T06:45:10 < Cracki> a quick search suggests that you might want to run something from flash, that then writes code to ram, triggers reset and boot from ram, and from then on doesn't need to use flash
2020-02-05T06:45:22 < dirty_d> wait
2020-02-05T06:45:34 < dirty_d> reset resets the ram though?
2020-02-05T06:46:10 < Cracki> I think that can be worked around
2020-02-05T06:46:34 < dirty_d> maybe some kind of soft swd reset?
2020-02-05T06:46:48 < Cracki> under debugger control lots is possible
2020-02-05T06:46:54 < Cracki> but when it runs on its own...
2020-02-05T06:47:14 < Cracki> there is at least the mechanism of backup sram, which you can carry over across boots
2020-02-05T06:48:09 < Cracki> I'm not even sure what clears sram, it might be the core itself or it might be startup code that is executed (or not)
2020-02-05T06:48:30 < dirty_d> i think it's physically a wire connected to everything
2020-02-05T06:48:33 < Cracki> I'm not even sure if that's even done, except for whatever your programming language requires (C: global vars)
2020-02-05T06:48:51 < dirty_d> i did some fpga stuff, and reset basically is connected to everything
2020-02-05T06:49:02 < Cracki> so unless you work around what C does by default, you wouldn't even notice that ram contents are still there
2020-02-05T06:49:34 < dirty_d> the external reset signal cascades across the entire logic and sets registers to a known state
2020-02-05T06:49:44 < dirty_d> but you dont have to do that
2020-02-05T06:50:10 < dirty_d> you can conditionally reset parts of the logic
2020-02-05T06:50:14 < Cracki> I'm sure the answers can be found in the RM and maybe programmer's manual and cortex m docs

2020-02-05T06:50:30 < Cracki> you're talking about registers, not ram
2020-02-05T06:50:35 < Cracki> ram isn't necessarily cleared
2020-02-05T06:50:40 < dirty_d> im not sure if all stm32 have this, but the stm32g4 has registers to reset basically every peripheral I think
2020-02-05T06:50:55 < Cracki> I'm trying to find out if it gets cleared and by what.
2020-02-05T06:51:05 < Cracki> again, registers aren't sram
2020-02-05T06:51:26 < Cracki> sram isn't equal to memory space
2020-02-05T06:51:58 < dirty_d> right
2020-02-05T06:52:06 < Cracki> https://stackoverflow.com/questions/29509985/keep-some-ram-values-on-reset-cortex-m3
2020-02-05T06:52:19 < dirty_d> but it could still have a reset signal that resets everything
2020-02-05T06:53:02 < Cracki> you can find that out from docs
2020-02-05T06:56:17 < Cracki> https://mcuoneclipse.com/2014/04/19/gnu-linker-can-you-not-initialize-my-variable/
2020-02-05T06:56:30 < Cracki> and that is only to work around C's normal semantics
2020-02-05T06:56:48 < Cracki> so no, I believe sram is not cleared by hardware explicitly
2020-02-05T06:57:28 < dirty_d> The CCMSRAM can be erased with a system reset using the option bit CCMSRAM_RST in
2020-02-05T06:57:28 < dirty_d> the user option byte
2020-02-05T06:57:38 < dirty_d> so i guess the normal sram isnt reset
2020-02-05T06:58:17 < Cracki> that's CCM ram, a particular part of ram
2020-02-05T06:58:50 < Cracki> bus matrix diagram will explain
2020-02-05T07:00:18 < dirty_d> so yea, I think you can load something to ram, and then use the option bytes to set the next reset to boot from the ram, then do a system reset from software

2020-02-05T11:41:46 < karlp> dirty_d: reset doesn't reset ram. onlyt thing that clears ram is your own startup code zeroing (or not, if you like) bss and writing (again, or not) .data
2020-02-05T11:42:36 < karlp> like here: https://github.com/libopencm3/libopencm3/blob/master/lib/cm3/vector.c#L67-L75
2020-02-05T11:42:41 < karlp> there's similar things in the cmsis startup code.
2020-02-05T11:43:07 < karlp> I'm pretty sure it's guarantteed to be zero at power on reset, but that's not exactly reliable.

2020-02-05T13:10:03 < Jak_o_Shadows> Note: Turn on the damn peripherals
2020-02-05T13:19:28 < qyx> that may help
2020-02-05T13:19:49 < Jak_o_Shadows> Gets me every bloody time
2020-02-05T13:19:59 < specing> its always the damn peripherals
2020-02-05T13:20:32 < specing> my ADC reading of a pin is off by 3 LSB and the reading of VREFINT is off by 17 LSB (according to multimeter)
2020-02-05T13:20:36 < specing> Is this normal?
2020-02-05T13:23:03 < karlp> how can you say that vrefint is "off" ? it has a range itself, and you can't measure it.
2020-02-05T13:23:17 < karlp> are you saying that after back calculating to vdda you get a different voltage?
2020-02-05T13:23:59 < qyx> off by 3 LSB is okish to me
2020-02-05T13:28:44 < specing> karlp: indeed
2020-02-05T13:29:51 < specing> I am reading 1686: VREFINT_CAL * 3300 / 1689 = 3010 mV, While both multimeters are reading 2980 mV: VREFINT_CAL * 3300 / 1706
2020-02-05T13:38:36 < PaulFertser> 17 LSB is certainly not normal
2020-02-05T13:46:30 < zyp> did you run ADC calibration?
2020-02-05T13:54:30 < karlp> if it's only 3 off on the actual reading, but 17 on intref, I'd say you're missing something.
2020-02-05T13:56:19 < srk> it's always the damn peripherals or af or interrupts or gazillion other little things you need to take care of 
2020-02-05T14:00:27 < specing> zyp: yes, of course
2020-02-05T14:01:06 < specing> zyp: also using the slowest sampling possible on 48 Mhz clock
2020-02-05T14:07:13 < PaulFertser> Assuming the results are consistent... Are you measuring with a DMM attached directly (or at least very close to) Vdda/Vssa ?
2020-02-05T14:09:00 < specing> PaulFertser: as close as the discovery kit allows, yes
2020-02-05T14:09:53 < specing> It has long pins going through the board, the top part of them I use for DMM/scope, the lower part goes into my breadboard.
2020-02-05T14:11:26 < PaulFertser> specing: I mean I'd be touching stm32 pins directly with fine tips but if it's a disco kit I'd assume layout there is good enough so any place should work.
2020-02-05T14:11:55 < specing> PaulFertser: I don't have fine enough tips for that
2020-02-05T14:14:26 < PaulFertser> specing: does disco board really use 3.0 V for Vcc? I thought all of them are on ~3.3 V.
2020-02-05T14:21:00 < specing> PaulFertser: yes, there is a 3v3 regulator and then a schottky after it
2020-02-05T14:22:06 < PaulFertser> specing: after, huh?
2020-02-05T14:22:49 < specing> PaulFertser: yes
2020-02-05T14:25:16 < PaulFertser> But what is it for there?
2020-02-05T14:31:32 < specing> PaulFertser: My guess is that it is for powering the system from an external power supply
2020-02-05T14:36:45 < PaulFertser> specing: I see, it might make sense. Do you get consistent results if you recalibrate it by recalculating VREFINT_CAL first?
2020-02-05T14:37:11 < PaulFertser> specing: and have you checked the errata? Some stm32 parts had issues, at least with the temperature calibration.
2020-02-05T14:37:59 < specing> PaulFertser: nah, had not checked the errata yet
2020-02-05T14:47:10 < qyx> you already spent days hunting for your missing LSBs
2020-02-05T14:47:40 < qyx> even with the fact that vrefint is not precise enough for few LSBs to matter
2020-02-05T14:47:51 < qyx> idk what are you trying to achieve
2020-02-05T14:48:05 < qyx> also schottky Vf varies with current
2020-02-05T14:49:12 < qyx> so it may not be true VDDA is 2.98V during convbersion
2020-02-05T14:49:22 < zyp> what's a good buck that'd do 24V->5V at a couple of amps? zypsnips doesn't look very up to date on bucks
2020-02-05T14:50:07 < qyx> someone found a rohm part for 5V/8A recently
2020-02-05T14:50:16 < zyp> that sounds excessive
2020-02-05T14:50:24 < specing> qyx: nah, I've been doing other stuff
2020-02-05T14:50:24 < karlp> yeah, I've got a few open in tabs at home too, and that syxxx part someone shared the other dya
2020-02-05T14:50:42 < specing> qyx: I was just asking if 3/17 lsb off is normal
2020-02-05T14:50:44 < karlp> but nothing that has universal "just use this" answers like we've got for sot23 ldos for instance.
2020-02-05T14:50:53 < specing> qyx: => to know if I have to do anything more
2020-02-05T14:50:57 < karlp> I think 3 is normal, and 17 is inconsistent with 3, and therefore should be ignored.

2020-02-05T15:25:19 < zyp> possibly
2020-02-05T15:25:40 < zyp> but the way the capacitors are placed close to the NC pads instead of the actual input pad

2020-02-05T15:34:57 < zyp> hmm, RT8299 looks decent enough, but 24V limit is cutting it a bit close for actual 24V operation

2020-02-05T17:54:48 < PaulFertser> Also, sed syntax is based on "ed" syntax which is the standard text editor. So the idea to use A,Bp should be obivous ;)

2020-02-05T18:10:22 < jadew> invzim, I talked to a contact from China about 2 days ago, and she didn't seem worried at all
2020-02-05T18:10:32 < jadew> she said everyone is staying inside

2020-02-05T18:10:51 < jadew> and that work will resume in February

2020-02-05T18:12:21 < kakihack> binwalk returned nothing
2020-02-05T18:14:00 < kakihack> so

2020-02-05T19:15:50 < zyp> hmm, this opensource fpga stuff actually works
2020-02-05T19:16:07 < zyp> at least to build a blinky
2020-02-05T19:16:29 < englishman> cool
2020-02-05T19:16:40 < englishman> why use it over lattice's tools tho?
2020-02-05T19:16:52 < karlp> from the slides (no experience) it's way faster
2020-02-05T19:17:52 < zyp> I can't comment on lattice's tools, but I assume they are more or less as much of a hassle to use as xilinx' tools
2020-02-05T19:18:30 < zyp> idk about speed, a full build and flash of this thing takes 4.4s
2020-02-05T19:18:43 < zyp> but this is as low complexity as it gets
2020-02-05T19:19:00 < jpa-> icecube is kind of nice and simple, but it sometimes messes up the project file for no reason at all
2020-02-05T19:19:13 < zyp> project file?
2020-02-05T19:19:16 < jpa-> (icecube being the lattice IDE for some of the products)
2020-02-05T19:19:28 < zyp> ah, right
2020-02-05T19:20:11 < zyp> well, I don't wanna dick with any IDEs or anything
2020-02-05T19:21:11 < jpa-> yeah, i also prefer if i can just "make"
2020-02-05T19:21:19 < jpa-> you probably just "scons" ;)

2020-02-05T19:22:22 < zyp> nah, doesn't seem very worthwhile to bother with that kind of build systems for fpga projects
2020-02-05T19:22:58 < zyp> since you don't have a bunch of translation units that gets built independently and linked in the end
2020-02-05T19:23:16 < jpa-> i think it is quite useful for automatically running test benches for the files that changed

2020-02-05T19:30:57 < jpa-> something doesn't quite add up; wuhan being 11 million people in the city, one would expect about 400 deaths any given day; if each funeral home is working at overcapacity, that would mean about 1000 extra deaths per day and thus at least 7000 more deaths than have been reported, kind of surprising if normal media (as opposed to epoch times) hasn't picked up on it

2020-02-05T20:24:26 < kakihack> how do I make my linux laptop seem like a gateway to this ip cam?
2020-02-05T20:24:46 < kakihack> so I can set it's ip
2020-02-05T20:25:12 < Thorn> gateway?
2020-02-05T20:25:25 < Thorn> you need to run dhcpd on it probably
2020-02-05T20:25:30 < effractur> or just static ip
2020-02-05T20:26:29 < Thorn> depends on the camera. does it need dhcp or does it have a default static ip
2020-02-05T20:26:36 < rajkosto> the router stuff is in sysconf
2020-02-05T20:26:36 < kakihack> default ip unknown
2020-02-05T20:26:44 < rajkosto> you just need to enable ip.routing
2020-02-05T20:27:11 < Thorn> if the latter, add an ip in the same subnet to your ethernet interface
2020-02-05T20:28:22 < Thorn> something like: ip address add 192.168.99.37/24 dev eth0

2020-02-05T23:45:53 < kakihack> let me see if there is the same data
2020-02-05T23:49:02 < kakihack> how do I pass certain amount of bytes to crc32?
2020-02-05T23:49:06 < kakihack> from my image
2020-02-05T23:50:14 < Cracki> dd maybe?
2020-02-05T23:50:32 < Cracki> bs=1 then counts and all that are bytes
2020-02-05T23:56:13 < kakihack> https://paste.ee/p/e3NV9 grepped the first line of hex
2020-02-05T23:57:07 < kakihack> patterns boi
2020-02-05T23:57:51 < kakihack> every 0x4000 this pattern repeats
2020-02-05T23:58:50 < kakihack> let's say data is bogus
2020-02-05T23:59:10 < kakihack> maybe crc32 command could be used
2020-02-05T23:59:18 < kakihack> to extract real data
2020-02-05T23:59:43 < kakihack> *lets say data was bogus intentionally
2020-02-05T23:59:58 < kakihack> you would still want crc32 to work
--- Day changed Thu Feb 06 2020
2020-02-06T00:02:36 < kakihack> and crc32 has paratemeters address and how many bytes
2020-02-06T00:04:45 < kakihack> hmm
2020-02-06T00:04:59 < kakihack> indeed it let's me go all the way to 1 byte
2020-02-06T00:07:28 < kakihack> okay
2020-02-06T00:07:40 < kakihack> pattern exists in crc32 too
2020-02-06T00:08:15 < kakihack> bytes seperated by 0x4000 have the same crc32 value
2020-02-06T00:09:45 < Cracki> so... dump failed? dump wrapped for some reason? any type of segmented memory?
2020-02-06T00:09:58 < kakihack> no
2020-02-06T00:10:11 < kakihack> I'm reading these values manually now from the device
2020-02-06T00:10:14 < Cracki> some kind of disk structure?
2020-02-06T00:11:01 < Cracki> uhm, do you crc32 single bytes? or the whole 16k block?
2020-02-06T00:12:05 < kakihack> single bytes
2020-02-06T00:12:11 < kakihack> maybe it's a disc structure
2020-02-06T00:21:01 < kakihack> maybe I should try to compress that image
2020-02-06T00:21:14 < kakihack> and see the ratio
2020-02-06T00:21:24 < kakihack> high ratio = contains no information
2020-02-06T00:21:37 < kakihack> low ratio = contains information

2020-02-06T00:24:36 < kakihack> forever
2020-02-06T00:24:45 < jadew> that means that your china packages could be contaminated

2020-02-06T00:33:29 < kakihack> they said these cameras are easy practice
2020-02-06T00:37:47 < kakihack> >>actually relativelly secure

2020-02-06T00:38:06 < kakihack> not the cheapest

2020-02-06T01:51:20 < jadew> so between 2020 and the end of next millennium?
2020-02-06T01:51:33 < specing> lol
2020-02-06T01:51:55 < jadew> when the Chinese will recover their numbers and have cheap labor once again
2020-02-06T01:52:33 < qyx> thats at aisler, not china
2020-02-06T01:52:53 < qyx> I am curious if that SEPA direct debit is gonna work
2020-02-06T01:52:53 < jadew> did you make other boards with them?
2020-02-06T01:53:11 < qyx> no, ordering for the first time
2020-02-06T01:53:37 < qyx> so far no problem
2020-02-06T01:53:41 < jadew> maybe I'll try them out too, but I hear they leave mouse bites on the edges of PCBs
2020-02-06T01:53:45 < jadew> not sure how I feel about that
2020-02-06T01:53:53 < qyx> heh
2020-02-06T01:54:01 < jadew> on the other hand, elecrow's silkscreen turns yellow

2020-02-06T01:57:19 < jadew> what would be my best choice? go to a supplier in china or buy some random brand off of amazon
2020-02-06T01:57:21 < jadew> ?
2020-02-06T01:57:48 < Cracki> definitely compare
2020-02-06T01:57:55 < qyx> I would got for a low-cost model from a reputable manufacturer, samsung of sorts
2020-02-06T01:58:21 < jadew> they have to run for several years, they'll always be plugged in
2020-02-06T01:58:33 < jadew> and they'll only run the one application
2020-02-06T01:58:42 < aandrew> anyone here got a bit of physics education?

2020-02-06T01:59:52 < qyx> yeah
2020-02-06T01:59:54 < Cracki> except fraction
2020-02-06T01:59:55 < qyx> km/h is kmh^-1
2020-02-06T01:59:57 < aandrew> similarly looking at raman spectrograph output and the wavenumber along the x axis is cm^-1
2020-02-06T02:00:06 < Cracki> same thing
2020-02-06T02:00:12 < Cracki> s^-1 is Hz (1/s)
2020-02-06T02:00:37 < aandrew> right, but what is that when referring to a volumetric measuremnt?
2020-02-06T02:00:44 < Cracki> thing per volume
2020-02-06T02:00:45 < aandrew> I mean the inverse of time is period
2020-02-06T02:00:52 < Cracki> such as grams per cubic centimeter
2020-02-06T02:00:53 < Cracki> density.
2020-02-06T02:01:01 < Cracki> don't overthink it
2020-02-06T02:01:23 < Cracki> read the division as "per"
2020-02-06T02:02:02 < Cracki> or literally "over". distance over time, mass per volume, ...
2020-02-06T02:03:40 < jadew> aandrew, did you get your answer?
2020-02-06T02:03:44 < jadew> what Cracki said is correct
2020-02-06T02:03:51 < Cracki> what kinda xray gives you mass density? I'm familiar with "hounsfield" units, -1000 is air, 0 is water, soft tissues hundreds, bone beyond about 1000
2020-02-06T02:03:58 < jadew> cm^-3 would be x g / cm^3
2020-02-06T02:04:51 < Cracki> and without knowing much about how matter reacts to xrays, I would say you need to know what substance you're xraying to calculate absorption into mass density

2020-02-06T13:25:31 < Thorn> does uncertainty in the Fourier transform only arise if the input function is nonperiodic?
2020-02-06T13:26:00 < jpa-> uncertainty?
2020-02-06T13:26:47 < jpa-> if you mean spectral leakage, it occurs whenever the input buffer length is not evenly divisible by the input frequency
2020-02-06T13:28:12 < Thorn> I don't mean the discrete transform
2020-02-06T13:28:13 < Thorn> https://en.wikipedia.org/wiki/Fourier_transform#Uncertainty_principle
2020-02-06T13:28:47 < Thorn> the discrete case adds more uncertainty on top of that
2020-02-06T13:29:05 < Thorn> the amount of which depends of f_s
2020-02-06T13:29:07 < Thorn> if I understand correctly
2020-02-06T13:31:49 < jpa-> so, if you do not mean the discrete transform, what do you mean then? symbolic calculation of fourier transform doesn't have uncertainty, as you have the symbolic representation of the input and thus know it perfectly
2020-02-06T13:33:06 < Thorn> if I could formulate it I wouldn't have any more questions lol
2020-02-06T13:33:22 < jpa-> if you mean continuous transform in limited time window calculated in some weird way (differential equations & numerical integration?), then yeah, it is precise if and only if the input is periodic and the period evenly divides the time window you integrated over
2020-02-06T13:33:39 < Thorn> but there are multiple videos on youtube for example if you search for https://www.youtube.com/results?search_query=fourier+uncertainty
2020-02-06T13:34:33 < jpa-> so the Gabor limit, i.e. "a function cannot be both time limited and band limited"
2020-02-06T13:36:13 < jpa-> i think the parallel to "a particle cannot be both place limited and velocity limited" is clever, but probably not very useful practically
2020-02-06T13:37:22 < jpa-> in the first video from the search, https://www.youtube.com/watch?v=MBnnXbOM5S4  the "you cannot know the frequency exactly from short observation" is only true for the discrete case
2020-02-06T13:38:06 < jpa-> (or continuous case with noise, but once you bring noise into this consideration your brain will bend too much)

2020-02-06T14:35:47 < Thorn> but he's not talking about the discrete case or noise
2020-02-06T14:37:02 < jpa-> Thorn: well, i think he is atleast thinking about discrete case, otherwise what he is saying makes no sense
2020-02-06T14:37:37 < jpa-> (but continuous fourier transform is something that has very few practical applications, so many people mean discrete case by default)
2020-02-06T14:38:46 < Thorn> I've never seen DFT in the context of quantum mechanics though
2020-02-06T14:46:22 < jpa-> yeah, i think the explanation in the video is a bit simplified and doesn't hold up under rigorous analysis

2020-02-06T17:03:33 < BrainDamage> indetermination principle for fourier transform becomes because it's a self adjoint commutating operator
2020-02-06T17:03:42 < BrainDamage> so it means it's intrinsec to the definition

2020-02-06T17:11:32 < BrainDamage> jpa-: the indetermination principle is that when you do the fourier transform, you lose the spatial information of the peaks, as in, you cannot determine what part of the input gave source of what part of the spectrum, and if you truncate the input to do a selection, you're convolving the output by a sinc 'spreading' the spectrum, so you have a limit to your temporal resolution
2020-02-06T17:12:00 < BrainDamage> this is intrinsec even if your input is symbolically defined

2020-02-06T19:45:38 < mawk> you don't know what you're saying Steffanx 
2020-02-06T19:45:46 < mawk> Steffanx: I can understand many dutch now
2020-02-06T19:46:03 < mawk> I can understand 'hello I am here to repair the heater"
2020-02-06T19:47:42 < mawk> "de ui mag niet donker kleuren" it means that the onion cannot become dark right ? or that the onion can not become dark
2020-02-06T19:47:51 < BrainDamage> is that what you say before installing a bitcoin miner?
2020-02-06T19:48:01 < mawk> why aren't we all speaking a language without ambiguity now that's it's 2020
2020-02-06T19:48:05 < mawk> lol BrainDamage 
2020-02-06T19:48:11 < mawk> the heater is in the server room
2020-02-06T19:48:15 < mawk> and the guy worked there without supervision
2020-02-06T19:48:30 < mawk> so yeah I thought he may be an industrial spy, so I asked for confirmation that we expected a heater repair guy
2020-02-06T19:48:51 < karlp> a heater in the serverroom sounds practical....
2020-02-06T19:49:05 < mawk> it's cold in the server room
2020-02-06T19:49:16 < mawk> you need a heater when you want to hide in it
2020-02-06T19:50:17 < BrainDamage> do you really need physical access?
2020-02-06T19:50:29 < BrainDamage> for most of the things you shouldn't
2020-02-06T19:50:47 < mawk> well when I asked why we are not taking care of the network ourselves they answered "it's not our job, we pay someone so that it is secure and we don't have to care about it"
2020-02-06T19:50:53 < mawk> so I sure hope physical access is the only way

2020-02-06T19:59:24 < mawk> it cannot get dark
2020-02-06T19:59:27 < Steffanx> But ui? Why would you let a ui become dark?
2020-02-06T19:59:34 < mawk> because it's tasty
2020-02-06T19:59:40 < Steffanx> Yes it can, but you shouldn't.

2020-02-06T20:06:42 < mawk> what's the rule for plural termination in dutch Steffanx ???
2020-02-06T20:06:45 < mawk> I don't understand at all
2020-02-06T20:06:50 < mawk> sometimes en, sometimes s
2020-02-06T20:06:53 < PaulFertser> Steffanx: unless you plan to stay in C land forever you should try haskelling too ;) Exercise your brains, man!
2020-02-06T20:07:10 < mawk> deep diving into normal forms and laziness PaulFertser 
2020-02-06T20:07:35 < Steffanx> "Hakselen" is actually dutch and that's what you can do when you make stamppot. It's a very bad wordplay PaulFertser 
2020-02-06T20:07:36 < Thorn> y combinator: 3 lines of code
2020-02-06T20:07:42 < Thorn> real world problems: never

2020-02-06T20:08:14 < PaulFertser> mawk: isn't laziness "just" an implementation detail? Yes, it affects practical computations in certain cases (where you e.g. return a lazy infinite sequence and then take just part of it) but isn't it about it?
2020-02-06T20:08:22 < Steffanx> There is no word "termination" in dutch. mawk 
2020-02-06T20:08:46 < Steffanx> Oh
2020-02-06T20:08:49 < Steffanx> Lol
2020-02-06T20:08:56 < Steffanx> I misread what you said
2020-02-06T20:09:19 < PaulFertser> Steffanx: if I knew what stamppot was I'd say the pun was funny, not bad.
2020-02-06T20:09:50 < Steffanx> Stamppot is the most dutch food you can get PaulFertser .
2020-02-06T20:10:43 < Thorn> has anyone pirated the x chapters yet
2020-02-06T20:10:53 < PaulFertser> Steffanx: so basically mashed potatoes with other random vegetables/fruits mashed in.
2020-02-06T20:11:16 < Steffanx> The famous potatoes, and whatever vegetable cooked together. And when it's cooked you mash it. Yes
2020-02-06T20:11:50 < Steffanx> I dont know what the rules are mawk. I just "know".
2020-02-06T20:12:11 < Ultrasauce> i preordered the x chapters book and it came with the worst print job ive ever seen for a textbook
2020-02-06T20:12:51 < Thorn> hopefully the ebook is usable
2020-02-06T20:13:01 < mawk> well if the language was always strict I wouldn't have to worry about it PaulFertser 
2020-02-06T20:13:06 < mawk> but it's not
2020-02-06T20:13:12 < mawk> also it's useful to use I guess
2020-02-06T20:13:50 < srk> how would you [0..] then? :)
2020-02-06T20:14:20 < PaulFertser> Steffanx: do you also have those "grammatical genders" where you just have to learn by heart that a ship should be called "she" or like they have der/die in German etc?
2020-02-06T20:14:44 < Steffanx> Kinda. 
2020-02-06T20:14:51 < BrainDamage> we have grammatical genders, but you don't have to learn them by heart
2020-02-06T20:15:02 < BrainDamage> the last vocal of the noun determines the gender
2020-02-06T20:15:21 < BrainDamage> you have to learn by heart the exceptions
2020-02-06T20:15:27 < PaulFertser> srk: I think some Haskell pioneers were saying laziness by default was an unfortunate choice.
2020-02-06T20:16:11 < PaulFertser> BrainDamage: it's similar in russian, luckily
2020-02-06T20:16:47 < srk> PaulFertser: possible, it's not that difficult to force evaluation if needed either via seq or BangPatterns
2020-02-06T20:17:22 < BrainDamage> what annoyes me in english is the "i" and "a" pronounciation that depends where they borrowed the word from
2020-02-06T20:17:30 < BrainDamage> "e" too
2020-02-06T20:17:38 < BrainDamage> so it's utterly arbitrary
2020-02-06T20:17:49 < PaulFertser> srk: I've heard it's sometimes difficult to realise what exactly is problematic in the code and where it should be forced best.
2020-02-06T20:18:07 < srk> sometimes you remove prints and wonder what's going on :)
2020-02-06T20:18:27 < srk> space leaks are more problematic to find and fix imho
2020-02-06T20:18:45 < mawk> BrainDamage: in dutch there is the neutral gender, and there is a combined gender for he/she
2020-02-06T20:18:46 < PaulFertser> BrainDamage: too much legacy in English indeed. Let's switch to Pidgin ;)
2020-02-06T20:18:52 < mawk> mashed up from german which has the 3 I guess
2020-02-06T20:19:14 < PaulFertser> srk: but laziness can easily lead to space leaks I heard?
2020-02-06T20:19:23 < srk> indeed, it's certainly related
2020-02-06T20:20:17 < PaulFertser> Lambda calculus doesn't care about laziness, so it doesn't really affect semantics.
2020-02-06T20:21:06 < mawk> yeah but we run code on computers
2020-02-06T20:21:10 < mawk> we need laziness
2020-02-06T20:21:51 < mawk> if we insist on using fp
2020-02-06T20:22:15 < PaulFertser> It seems like the consensus is that laziness-by-default usually makes reasoning about program _behaviour_ (that is, running it on real hardware) harder.
2020-02-06T20:22:29 < mawk> I don't see why yet
2020-02-06T20:22:39 < mawk> well there is this strictness analyzer business
2020-02-06T20:22:44 < mawk> which seems a bit heuristical to me
2020-02-06T20:22:59 < mawk> but if people explicitely use seq to mark things they want as strict they don't have to reason about any analyzer
2020-02-06T20:23:54 < aandrew> haha
2020-02-06T20:24:01 < aandrew> C wins programming language of the year award in 2019
2020-02-06T20:24:05 < mawk> lol
2020-02-06T20:24:31 < mawk> I finally just started moving my system programming to C++ some weeks ago
2020-02-06T20:24:34 < mawk> before hesitating with D
2020-02-06T20:24:45 < PaulFertser> Why not Rust mawk ?
2020-02-06T20:24:47 < BrainDamage> D's modules look kinda neat
2020-02-06T20:25:17 < aandrew> https://jaxenter.com/c-tiobe-2019-166456.html
2020-02-06T20:25:24 < mawk> some cool D feature is universal function call, if you have like a f(T) function somewhere you can do t.f() instead of f(t)
2020-02-06T20:25:27 < srk> looks like OCaml is good for systems programming as well :)
2020-02-06T20:25:30 < mawk> you can chain a lot of calls like that
2020-02-06T20:25:37 < specing> Why not Ada, mawk ?
2020-02-06T20:25:45 < aandrew> Everybody thought that Python would become TIOBE’s programming language of the year for the second consecutive time. But it is good old language C that wins the award this time with an yearly increase of 2.4%. Runners up are C# (+2.1%), Python (+1.4%) and Swift (+0.6%). 
2020-02-06T20:25:51 < mawk> I was force-fed ada at school specing 
2020-02-06T20:25:54 < mawk> I don't know PaulFertser 
2020-02-06T20:26:01 < mawk> I don't see myself rewriting wrappers all day also
2020-02-06T20:26:05 < mawk> which is why I didn't pick D
2020-02-06T20:26:17 < mawk> even though D is very compatible with C and C++ it was still a pain
2020-02-06T20:26:19 < mawk> so I don't imagine the rest
2020-02-06T20:26:22 < srk> rust looks weird, bit like ruby
2020-02-06T20:26:31 < srk> too much boilerplate
2020-02-06T20:26:35 < srk> and unwrapping
2020-02-06T20:26:42 < PaulFertser> mawk: but C++ gives so long complex obscure errors... And still doesn't support lifetime tracking/borrow checking.
2020-02-06T20:26:46 < mawk> it's for your own safety srk 
2020-02-06T20:26:50 < mawk> G++ does PaulFertser 
2020-02-06T20:27:02 < mawk> clang is better for warnings and errors
2020-02-06T20:27:04 < jpa-> it's like christmas every day, unwrapping all the rust presents
2020-02-06T20:27:13 < mawk> lol
2020-02-06T20:27:15 < mawk> but I agree when templates are involved it's still not perfect
2020-02-06T20:27:31 < mawk> also I'm not sure what lifetime tracking is
2020-02-06T20:27:38 < mawk> I guess a complex version of ref counting
2020-02-06T20:27:40 < srk> there's even a decoder for STL error messages :D
2020-02-06T20:27:42 < PaulFertser> mawk: before "concepts" there's no way round that when the magic of templates is involved.
2020-02-06T20:27:43 < mawk> lol
2020-02-06T20:28:01 < mawk> it's an excuse to get a high salary as a C++ engineer
2020-02-06T20:28:04 < specing> PaulFertser: say what? make >/dev/null | head :)
2020-02-06T20:28:08 < mawk> I hope they never introduce concepts
2020-02-06T20:28:38 < PaulFertser> mawk: ref counting would be overhead. But Rust has compile-time lifetime tracking. E.g. you can't pass a reference to some object and then get that object destroyed while the other thread still thinks it's valid.
2020-02-06T20:29:04 < PaulFertser> mawk: I think concepts are in the latest standard
2020-02-06T20:29:04 < mawk> ah I see
2020-02-06T20:29:10 < mawk> not yet
2020-02-06T20:29:16 < mawk> well, in the latest draft standard yes
2020-02-06T20:29:21 < mawk> unless C++20 came out and I'm not aware of it
2020-02-06T20:29:41 < PaulFertser> I meant C++20 yes.
2020-02-06T20:29:49 < PaulFertser> So basically that's inevitable by now.
2020-02-06T20:30:10 < mawk> designated initializers[8] (based on the C99 feature)
2020-02-06T20:30:12 < mawk> lol
2020-02-06T20:30:20 < mawk> it took them that much time to REintroduce this feature
2020-02-06T20:30:48 < mawk> wow a new operator
2020-02-06T20:30:50 < mawk> <=>
2020-02-06T20:32:18 < BrainDamage> on a tangential note, does anyone here use one of those fancy fonts with ligatures replacing the operators?
2020-02-06T20:32:44 < BrainDamage> I can't help but think I'd get throw off, but I want some opinions from someone who uses them, maybe I'm doing it wrong
2020-02-06T20:33:33 < srk> wanted to but urxvt won't do that
2020-02-06T20:33:56 < srk> and I don't want to use some hyped gui term just to have ligatures
2020-02-06T20:34:25 < srk> or hyped vim like neovim
2020-02-06T20:40:16 < PaulFertser> mawk: you might want to write a lambda calculus evaluator in Haskell
2020-02-06T20:43:20 < PaulFertser> srk: do you think that's worth doing?
2020-02-06T20:45:00 < srk> PaulFertser: I won't switch from urxvt + vim that easily so not for me but if you use modern editors it's fine
2020-02-06T20:45:31 < srk> it will transparently switch between ascii representation and redraw with ligatures when cursor is away
2020-02-06T20:45:57 < PaulFertser> srk: I'm not talking about ligatures/terminals/editors :)
2020-02-06T20:46:16 < srk> ah, evaluator
2020-02-06T20:46:45 < srk> http://dev.stephendiehl.com/fun/
2020-02-06T20:47:12 < PaulFertser> It kinda felt trivial but made me spent a fair bit of time and made me better understand the ways to do substitutions. So for a novice like me certainly was useful.
2020-02-06T20:47:20 < srk> very good even if you only go thru first chapters
2020-02-06T20:47:43 < PaulFertser> srk: I was only reading the wikipedia page on lambda calculus, plus basic Haskell knowledge, no cheating.
2020-02-06T20:48:50 < srk> nice :)
2020-02-06T20:49:23 < srk> I'm trying to work my way thru TAPL (Types and programming languages) to understand all this a bit better
2020-02-06T20:50:00 < srk> and this .. https://softwarefoundations.cis.upenn.edu/
2020-02-06T20:51:17 < PaulFertser> srk: I never got far enough lacking real life tasks and support from my human peers :(
2020-02-06T20:51:59 < srk> :(
2020-02-06T20:53:12 < mawk> BrainDamage: I replace the operators with the word equivalents
2020-02-06T20:53:17 < mawk> that's builtin in C++
2020-02-06T20:53:26 < mawk> if (not (A and B))
2020-02-06T20:53:35 < mawk> it's way cooler than ugly ! && or whatnot
2020-02-06T20:53:35 < srk> I feel like I could be way ahead if I pursued right stuff at uni, now need to catch up on some topics to understand work of others 
2020-02-06T20:54:33 < PaulFertser> srk: here was my result: http://paste.debian.net/hidden/2a965a15/
2020-02-06T20:54:46 < srk> sel4 and echronos are quite interesting but to be able to understand their proofs, man
2020-02-06T20:54:55 < mawk> why are you not using the stm32-sponsored pastebin ???

2020-02-06T20:55:24 < srk> PaulFertser: so tiny :) cool!
2020-02-06T20:55:47 < mawk> I hope I can understand that code of yours once
2020-02-06T20:56:08 < BrainDamage> mawk: can you submit using a simple GET/POST request from the command line?
2020-02-06T20:56:29 < mawk> no BrainDamage you have to supply the csrf token
2020-02-06T20:56:35 < mawk> well technically if you get the token you can yes
2020-02-06T20:56:42 < mawk> it's two requests instead of one then
2020-02-06T20:56:54 < mawk> but on my image host there is an API endpoint, I just hid it so people don't use it
2020-02-06T20:56:56 < PaulFertser> srk: I never validated it with somebody knowledgeable. As I was a uni teacher myself back then, and so people I talked to knew even less than me :/
2020-02-06T20:56:59 < mawk> but that one is down because of police
2020-02-06T20:57:19 < mawk> but I can make an API endpoint for it if you want BrainDamage 
2020-02-06T20:57:35 < BrainDamage> nah, don't worry, I already have few services who can
2020-02-06T20:58:39 < PaulFertser> srk: iirc the quasiquoters paper/documentation had a mich nicer implementation
2020-02-06T21:00:39 < PaulFertser> mawk: I think I did an almost literal translation from wikipedia article to haskell. Just finding a proper (unclashing) name for free variables when substituting wasn't there.

2020-02-06T23:37:59 < Steffanx> lol why the excuse. :P
2020-02-06T23:38:11 < PaulFertser> It should be kinda obvious :/
2020-02-06T23:38:38 < Thorn> Progress is a cargo spacecraft. the system as a whole (and the LV)  is called Soyuz
2020-02-06T23:39:08 < PaulFertser> lol, you see Steffanx how lame my question was
2020-02-06T23:39:46 < PaulFertser> What was the name of that other rocket that was used a lot for cargo launches?
2020-02-06T23:39:47 < Thorn> same as the manned vehicle for Salyut/Mir/ISS, which is the confusing part
2020-02-06T23:39:57 < Thorn> Proton?

2020-02-06T23:46:45 < PaulFertser> Is that KSP animation or did they cook their own?

2020-02-06T23:53:40 < PaulFertser> So why Soyuz and not Proton?
2020-02-06T23:55:14 < Ultrasauce> proton is a heavy launch system and also phased out
2020-02-06T23:56:15 < zyp> qyx, wasn't really looking for high amp, more for 24V in
2020-02-06T23:57:28 < zyp> TPS56637 looks ineresting though
2020-02-06T23:57:38 < zyp> if it can be had at a reasonable price

2020-02-07T00:13:13 < kakinormal> in processors with external nand flash
2020-02-07T00:13:36 < kakinormal> does the flash even map to address space?
2020-02-07T00:14:07 < kakinormal> or do you interface it via peripheral of sorts
2020-02-07T00:15:17 < Ultrasauce> maybe you should look at your flash chip and see what the interface is

2020-02-07T00:17:41 < PaulFertser> kakinormal: nand flash is very unlikely to be mapped, as it always requires additional ECC and bad blocks management.
2020-02-07T00:18:08 < kakinormal> so md was never a way to extract firmware

2020-02-07T00:20:40 < kakinormal> uboot was crippled in such way there was no way to get data out only data in

2020-02-07T00:24:06 < kakinormal> is it normal to restrict updating of bootloader?

2020-02-07T00:27:16 < kakinormal> I found one yes
2020-02-07T00:27:30 < kakinormal> but I try to understand basics
2020-02-07T00:27:51 < kakinormal> https://openipc.org/
2020-02-07T00:27:56 < BrainDamage> kikakivion
2020-02-07T00:28:15 < PaulFertser> kakinormal: I wouldn't expect a camera to have trusted boot.
2020-02-07T00:28:42 < kakinormal> but uboot may have some signature check for stuff you try to upload right?
2020-02-07T00:28:50 < PaulFertser> kakinormal: many nand chips have "guaranteed" first N kiB area, and SoCs have ROM bootloader that knows how to read from there.
2020-02-07T00:29:17 < kakinormal> how much is usually read?
2020-02-07T00:29:34 < kakinormal> there is header that tells to rom bootloader that?
2020-02-07T00:29:42 < PaulFertser> Few kibibytes I'd say.
2020-02-07T00:29:55 < kakinormal> fixed?
2020-02-07T00:30:04 < BrainDamage> many soc chainload bootloaders
2020-02-07T00:30:15 < BrainDamage> so you run first the vendor uboot, then your own
2020-02-07T00:30:21 < PaulFertser> kakinormal: there're many different SoCs with different ROM bootloaders...
2020-02-07T00:30:48 < kakinormal> can anyone provide an example processor?
2020-02-07T00:31:26 < kakinormal> this processor doesn't have technical reference in google
2020-02-07T00:32:54 < PaulFertser> kakinormal: you realise ROM bootloader is just a program, so different vendors can have very different behaviours and features there.
2020-02-07T00:33:04 < kakinormal> yes
2020-02-07T00:33:17 < kakinormal> but did someone say processor might even have uboot in rom?
2020-02-07T00:33:31 < kakinormal> that's interestings
2020-02-07T00:34:13 < PaulFertser> uboot in rom is unlikely. But probably fastboot idk?
2020-02-07T00:35:19 < kakinormal> BrainDamage: what vendor?
2020-02-07T00:35:30 < BrainDamage> yes
2020-02-07T00:35:38 < BrainDamage> the one of the soc
2020-02-07T00:35:46 < kakinormal> yes
2020-02-07T00:36:17 < BrainDamage> and you have to flash the vendor bootloader to the memory

2020-02-07T00:38:26 < kakinormal> BrainDamage: why not just skip that step?
2020-02-07T00:38:43 < kakinormal> vendor bootloader does some propiertary shiet?
2020-02-07T00:39:08 < BrainDamage> vendor uboot is generally configured to start another uboot
2020-02-07T00:39:15 < BrainDamage> so that you're free to run your shit
2020-02-07T00:39:45 < kakinormal> why not directly boot yo your own uboot
2020-02-07T00:40:53 < kakinormal> is it just redundancy?
2020-02-07T00:41:47 < kakinormal> does everybody else understand this?
2020-02-07T00:42:28 < PaulFertser> doomba: weird, not reproducible here
2020-02-07T00:42:56 < doomba> PaulFertser: maybe i'm missing something or it's btrfs
2020-02-07T00:43:23 < PaulFertser> kakinormal: sometimes when modding devices people prefer to not overwrite vendor bootloader to avoid the danger of "bricking" the device, especially if it has no usable ROM bootloader.
2020-02-07T00:44:03 < kakinormal> how do you flash it initially?
2020-02-07T00:45:17 < PaulFertser> kakinormal: vendor might be flashing the memory in a programming rig. Or knows some secret rom protocol.
2020-02-07T00:45:55 < PaulFertser> doomba: what if you retry that make with an additional V=1 argument?
2020-02-07T00:46:03 < PaulFertser> doomba: to see which command fails
2020-02-07T00:46:45 < jadew> apparently the nCoV data got leaked by mistake
2020-02-07T00:46:56 < jadew> 150k confirmed, 79k suspected
2020-02-07T00:47:01 < jadew> 269 recovered
2020-02-07T00:47:05 < jadew> and 24k dead
2020-02-07T00:47:14 < PaulFertser> jadew: where from?
2020-02-07T00:47:26 < jadew> some chinese website
2020-02-07T00:47:39 < BrainDamage> there was a tv trasmission where the values did swap
2020-02-07T00:47:53 < BrainDamage> but that's far off from being confirmed as correct
2020-02-07T00:47:54 < kakinormal> vendor being the device vendor?
2020-02-07T00:47:55 < PaulFertser> jadew: sounds unlikely, I'd bet it's not true.
2020-02-07T00:48:02 < kakinormal> or soc vendor?
2020-02-07T00:48:10 < PaulFertser> kakinormal: soc vendor doesn't flash anything usually.
2020-02-07T00:48:33 < PaulFertser> jadew: were you as concerned during the MERS-CoV?
2020-02-07T00:48:35 < jadew> PaulFertser, https://www.taiwannews.com.tw/en/news/3871594
2020-02-07T00:49:09 < jadew> PaulFertser, not as concerned
2020-02-07T00:50:43 < kakinormal> so
2020-02-07T00:50:51 < kakinormal> if there is no rom bootloader
2020-02-07T00:50:57 < PaulFertser> jadew: monaco prince died of pneumonia without any fancy nCoV
2020-02-07T00:51:52 < BrainDamage> 62% mortality would put it in the same ballpark as ebola or the plague
2020-02-07T00:52:22 < PaulFertser> BrainDamage: it takes much less time to die than to fully recover. So it's not 62%.
2020-02-07T00:52:30 < kakinormal> true
2020-02-07T00:52:44 < kakinormal> but more than official "fixed rate"
2020-02-07T00:53:41 < BrainDamage> PaulFertser: and not all the people infected got hospitalized, there's selection bias where you see only the one with worst symptoms
2020-02-07T00:53:58 < BrainDamage> altough that number is a bit fishy
2020-02-07T00:54:12 < BrainDamage> on a related note, a podcast from a real virologist: http://www.microbe.tv/twiv/
2020-02-07T00:54:13 < PaulFertser> BrainDamage: I think in countries like Germany all suspected people get tested.
2020-02-07T00:54:35 < PaulFertser> And of course all of those tested positives are isolated.
2020-02-07T00:54:40 < jadew> PaulFertser, until it gets out of hand
2020-02-07T00:54:58 < BrainDamage> there's infected people in the single digits outside china
2020-02-07T00:55:11 < BrainDamage> not a reliable source of statistics
2020-02-07T00:55:13 < PaulFertser> More than 10 in Germany.
2020-02-07T00:55:25 < PaulFertser> But yes, too few for proper statistics.
2020-02-07T00:57:28 < PaulFertser> jadew: the outcome of the A1H1 "swine flu" is quite impressive too.
2020-02-07T00:57:34 < kakinormal> in finland suspected people have 2 weeks sick leave
2020-02-07T00:57:46 < kakinormal> if not contacted to confirmed cases
2020-02-07T00:58:02 < jadew> PaulFertser, yeah, I saw a documentary on netflix I think where it said that it's considered seasonal flu in India
2020-02-07T00:58:08 < kakinormal> this is what internet anonymous says
2020-02-07T00:58:50 < PaulFertser> I wonder what countries made their own PCR tests based on the published genome data.
2020-02-07T00:59:12 < kakinormal> big ones
2020-02-07T00:59:21 < PaulFertser> jadew: plenty of deaths according to wikipedia :(
2020-02-07T00:59:22 < kakinormal> big western ones
2020-02-07T01:00:35 < BrainDamage> sars was quite deadly too
2020-02-07T01:00:38 < BrainDamage> 10-20%
2020-02-07T01:00:51 < jadew> shouldn't there be a vaccine for this stuff already?
2020-02-07T01:01:05 < kakinormal> if you made the virus yes
2020-02-07T01:01:05 < BrainDamage> developing a vaccine takes months/years
2020-02-07T01:01:24 < BrainDamage> and then if you go through the iter of approval, it takes at least 6 years

2020-02-07T01:04:03 < BrainDamage> I'm talking about the normal procedure
2020-02-07T01:04:19 < BrainDamage> if there's an epidemic around, I bet the requirements become more lax anyway
2020-02-07T01:04:34 < BrainDamage> the procedure is there to prevent distributing harmful medicines
2020-02-07T01:04:49 < BrainDamage> but if the risk is higher than the harm risk, I bet they can take a lot of shortcuts
2020-02-07T01:04:56 < BrainDamage> it just has to kill less than the disease
2020-02-07T01:06:03 < PaulFertser> BrainDamage: but they produce new flu vaccines each year
2020-02-07T01:06:27 < BrainDamage> those are based off skeleton vaccines they already know
2020-02-07T01:06:29 < PaulFertser> Or are they just combinations of old ones?
2020-02-07T01:10:02 < kakinormal> so if processor doesn't have rom bootloader
2020-02-07T01:10:14 < kakinormal> what loads the vendor bootloader from flash?
2020-02-07T01:10:36 < zyp> there's always a first stage loader to do that
2020-02-07T01:10:41 < jadew> the chinese dr. who reported nCoV also died
2020-02-07T01:10:48 < jadew> (just found out)
2020-02-07T01:10:48 < PaulFertser> kakinormal: with e.g. ar9331 there's a hardware SPI NOR / memmap translator.

2020-02-07T01:12:17 < BrainDamage> the H<number>N<number> are the evolution chains
2020-02-07T01:12:24 < jadew> zyp, there's no retraction on that article
2020-02-07T01:12:26 < PaulFertser> kakinormal: I think you can hardly find any modern SoC without a bootloader. Also, all of them have some kind of OCD so you can attach debugger, configure SDRAM controller and off you go. 
2020-02-07T01:12:31 < BrainDamage> where H1N1 is the orig 1918 spanish flu
2020-02-07T01:13:33 < jadew> zyp, according to that BBC article, the chinese were trying to cover up his death
2020-02-07T01:14:00 < kakinormal> it's eerie
2020-02-07T01:14:05 < kakinormal> like in some movie
2020-02-07T01:14:10 < zyp> oh, the article I read is updated again
2020-02-07T01:14:13 < kakinormal> first person to figure it out dies
2020-02-07T01:14:23 < zyp> apparently he was reported dead first, then still alive, now dead
2020-02-07T01:14:34 < kakinormal> they can't decide!
2020-02-07T01:14:40 < jadew> yeah, they were trying to cover it up
2020-02-07T01:14:47 < BrainDamage> that's what happens when you cannot trust the news
2020-02-07T01:14:57 < BrainDamage> welcome to china, where honour is more valuable than lives
2020-02-07T01:15:04 < kakinormal> truth and what is said are 2 different things in china
2020-02-07T01:15:07 < jadew> it's easy to say only old and sick people die
2020-02-07T01:15:17 < jadew> but the guy had the spotlights on him
2020-02-07T01:15:18 < zyp> alternatively that's what happens when people are in a hurry to report the news before it's actually happened
2020-02-07T01:17:30 < kakinormal> BrainDamage: not only china but especially china
2020-02-07T01:17:41 < kakinormal> generally south east asia
2020-02-07T01:19:49 < kakinormal> idk if honour is the word
2020-02-07T01:20:11 < kakinormal> sounds like middle east family tradition that one
2020-02-07T01:20:12 < PaulFertser> doomba: so what about V=1 ?

2020-02-07T01:25:43 < kakinormal> just redundancy and nothing else
2020-02-07T01:26:32 < PaulFertser> kakinormal: I can't understand your question.
2020-02-07T01:26:53 < kakinormal> vendor uboot
2020-02-07T01:27:18 < zyp> kakinormal, you generally don't have multiple stages of uboot
2020-02-07T01:27:33 < kakinormal> you could chain 2 uboot yourself and it would be the same thing than with vendor uboot
2020-02-07T01:27:42 < zyp> uboot is big and flexible
2020-02-07T01:27:55 < zyp> first stage vendor thing is usually small and dumb

2020-02-07T01:28:06 < zyp> and only does what's required to load and start uboot
2020-02-07T01:28:29 < zyp> might be more than just one stage too
2020-02-07T01:29:05 < zyp> might be a simple stage in rom that loads another vendor stage that then loads uboot
2020-02-07T01:30:52 < PaulFertser> barebox is probably nicer than uboot
2020-02-07T01:34:55 < kakinormal> usually there is only uboot right?
2020-02-07T01:34:58 < kakinormal> no chains
2020-02-07T01:35:37 < zyp> depends a lot
2020-02-07T01:35:58 < zyp> when I worked with phone stuff there were all sorts of bootloader chains depending on the vendor
2020-02-07T01:37:19 < kakinormal> phones are full of garbage
2020-02-07T01:38:11 < BrainDamage> tegra has a 3 stage bootloader
2020-02-07T01:38:26 < BrainDamage> and my odroid c1 has a two stage uboot ...
2020-02-07T01:38:31 < kakinormal> what are the stages?
2020-02-07T01:38:46 < BrainDamage> one bootloader loading another
2020-02-07T01:40:38 < kakinormal> why?
2020-02-07T01:41:34 < kakinormal> btw are the stages "invisible" until image cannot be loaded anymore?
2020-02-07T01:41:55 < kakinormal> "invisible" as in boot process cannot be altered in those stages
2020-02-07T01:44:01 < PaulFertser> uboot spl doesn't have interactive commands iirc
2020-02-07T01:44:43 < PaulFertser> kakinormal: e.g. first stage bootloader is small enough to fit into instruction cache and it knows just how to init DRAM and read from NAND.
2020-02-07T01:45:39 < kakinormal> oh
2020-02-07T01:45:43 < kakinormal> now i understand

2020-02-07T13:03:49 < doomba> oh for sure
2020-02-07T13:04:27 < doomba> in the spirit of archlinux, there is likely already a "make-unfucked" in AUR

2020-02-07T13:06:11 < doomba> i actually switched the project over to ST HAL
2020-02-07T13:06:30 < doomba> because after all of the nonsense getting st-link to see these g0's, it's been one thing after another

2020-02-07T13:08:08 < doomba> then libopencm3 wouldn't compile because of make 4.3
2020-02-07T13:08:31 < doomba> then i used a pre-compiled libopencm3 from another project
2020-02-07T13:08:50 < karlp> texane stlnk is a garbage fire.
2020-02-07T13:09:06 < doomba> yea i know. openocd won't compile
2020-02-07T13:09:11 < karlp> wat?
2020-02-07T13:09:29 < doomba> sysprogs and another repo both have the patches for g0
2020-02-07T13:09:34 < doomba> and their shit only builds for windows/macosx
2020-02-07T13:09:39 < karlp> won't compile?
2020-02-07T13:10:08 < doomba> they bastardized it too much
2020-02-07T13:10:19 < doomba> doesn't build with autotools/make or w/e
2020-02-07T13:10:25 < doomba> they added cmake and shit
2020-02-07T13:10:55 < doomba> and i donno why the upstream openocd doesn't include hardly any stm32 it seems
2020-02-07T13:11:34 < doomba> no g0/g4 yet. but someone patched texane stlink to work with g0 and it compiled
2020-02-07T13:12:25 < doomba> after all that, code that i confirmed works for stm32l4 and stm32f4 and stm32f1 - adapted it to stm32g0
2020-02-07T13:12:25 < karlp> doesn't included hardly any? what
2020-02-07T13:12:50 < doomba> is not driving usart correctly and i don't know why
2020-02-07T13:13:20 < englishman> karlp: yeah and not only is it paid, it's a yearly sub
2020-02-07T13:13:21 < englishman> fuck off
2020-02-07T13:14:02 < doomba> and i wasn't about to go down that rabbit hole without a debugger and using official st-link.exe in win10 vm to erase flash then use the modded texane to flash
2020-02-07T13:15:00 < doomba> so i ported it to HAL lol
2020-02-07T13:16:06 < karlp> I'm not sure how hal avoids your stlink/texane problems....
2020-02-07T13:16:16 < doomba> it doesn't. it avoids libopencm3 problems.
2020-02-07T13:16:32 < karlp> ok. communication A++ :)
2020-02-07T13:17:10 < doomba> if not for all the stlink/texanes/lack of openocd/doesn't work with nucleo and discovery stlink but works with the cheap chinesium stlink weirdness
2020-02-07T13:17:54 < doomba> wasted so many hours just trying to interact with the part and flash it - and only got as far as being able to erase and flash but not attach debugger
2020-02-07T13:18:30 < englishman> didnt you guys tell me not to use texane in like 2014
2020-02-07T13:18:34 < doomba> that by the time i realized libopencm3 usart for g0 is possibly broken, i was like "fuck it. use HAL. get this over wiht."
2020-02-07T13:19:03 < englishman> solid choice
2020-02-07T13:19:07 < englishman> except that win10 vm
2020-02-07T13:19:09 < englishman> the fuck
2020-02-07T13:19:12 < doomba> yea it's retarded
2020-02-07T13:19:24 < englishman> why would you run anything but win10 on your desktop
2020-02-07T13:19:44 < doomba> because i like pain
2020-02-07T13:20:49 < karlp> the guy who submited usart on g0 said it worked just fine, and it's the same peripheral as on other parts, so you're the first person reporting breakage.
2020-02-07T13:21:07 < karlp> sure you got all the clocks on?
2020-02-07T13:22:59 < doomba> pretty sure. i am 99.9% certain it's my code not libopencm3
2020-02-07T13:23:39 < doomba> it works on the other parts but not g0 for me though.
2020-02-07T13:23:54 < doomba> and at that point i was so fed up with all the bullshit with these things
2020-02-07T13:24:33 < doomba> like it's a one-off project so there's no incentive to neckbeard over openocd and the lib

2020-02-07T14:32:12 < BrainDamage> yes, the water makes it stronger instead of weaker, due to to osmotic pressure

2020-02-07T14:41:01 < invzim> kudos to ROHM, a European guy got me both recommended footprint and a 3d step model that has the odd footprint
2020-02-07T14:41:19 < invzim> (BD9F800MUX-ZE2 8A buck converter)
2020-02-07T14:43:06 < zyp> invzim, how much is that?
2020-02-07T14:43:47 < invzim> about 2 usd in qty 100

2020-02-07T14:44:55 < invzim> I've got close to zero experience with switching regulators, but I figure it's cheaper than TI & Friends, but several times more expensive than Chinese brands
2020-02-07T14:47:10 < zyp> I've been trying to select something similar to that
2020-02-07T14:47:26 < zyp> I need something that can do 24V->5V, but not necessarily that much current
2020-02-07T14:49:19 < invzim> The other one I'm looking at, https://lcsc.com/product-detail/DC-DC-Converters_Silergy-Corp-SY8368QNC_C125897.html
2020-02-07T14:49:48 < zyp> I looked at sy8366 the other day
2020-02-07T14:50:01 < invzim> looks good on paper to me
2020-02-07T14:50:52 < zyp> sy8366 has a weird footprint and a layout recommendation that doesn't make sense
2020-02-07T14:51:15 < zyp> sy8368 makes more sense in that regard
2020-02-07T15:09:47 < karlp> they both have the same footprint as far as I cna tell.
2020-02-07T15:10:14 < karlp> and the sheets I've got open have by all accounts identical layout recommendatoin?
2020-02-07T15:10:37 < karlp> one of them labels 2 pads NC, but they're clearly actually VIN/GND as on the other one, when you look at the layouts
2020-02-07T15:11:26 < karlp> 66 and 68 seem to only differ in 6A vs 8A?
2020-02-07T15:17:41 < karlp> I love how sy836[68] isn't on silergty's own website

2020-02-07T15:42:20 < aandrew> jadew: based on what is that estimate?
2020-02-07T15:42:36 < aandrew> the virus is proving to have an r0 of abotu 1.4-2.something
2020-02-07T15:44:08 < aandrew> BrainDamage: yep that's the weird thing about sterilization. water makes it (alcohol) more effective because it lingers longer (doesn't evaporate as fast) and water can help transport it where it needs to get, and as you said, osmotic pressure
2020-02-07T15:46:48 < englishman> wow adesto is way cheaper than gigadevice
2020-02-07T15:51:55 < jadew> BrainDamage, I'll wait a couple more days before I fix it
2020-02-07T15:51:58 < aandrew> GD32 was already pretty cheap, adesto is significantly moreso?

2020-02-07T15:52:50 < aandrew> jadew: oh yeah I'm just an armchair quarterback in this domain
2020-02-07T15:53:31 < jadew> thing is, the official information coming out of there is extremely lacking and fishy
2020-02-07T15:54:22 < jadew> so I'd say that whatever actual doctors are saying, is much closer to the truth
2020-02-07T15:55:15 < jadew> he's statements about the detection ratio are also interesting
2020-02-07T15:55:38 < jadew> the implication being that it's going to spread like wildfire
2020-02-07T15:57:46 < aandrew> canada jumped from 2-4-5-7 over this past 7 days or so

2020-02-07T16:00:26 < aandrew> the "outside of china" infection rate seems to be fairly linear
2020-02-07T16:01:19 < PaulFertser> aandrew++
2020-02-07T16:01:21 < aandrew> actually the inside china rate is also fairly linear
2020-02-07T16:01:30 < aandrew> it did have a nasty curve but it's flattened out
2020-02-07T16:01:44 < jadew> aandrew, it hasn't flattened out
2020-02-07T16:01:47  * aandrew checks to make sure it's not a log graph

2020-02-07T16:02:30 < jadew> but on the next day update it becomes clear that in fact the slope is the same/steeper
2020-02-07T16:02:36 < Cracki> wonder when they'll match the great leap forward numbers
2020-02-07T16:02:54 < aandrew> jadew: that's why I am ignoring the current day and trying to caputre 24h periods
2020-02-07T16:03:05 < aandrew> slope being same = linear :-)
2020-02-07T16:03:39 < Cracki> their numbers are quadratic
2020-02-07T16:03:41 < jadew> aandrew, sure, but I don't know if it's the same, there are only a couple of points there that would suggest that
2020-02-07T16:03:49 < jadew> and yeah, it's based on what china is reporting
2020-02-07T16:04:07 < aandrew> jadew: the past week numbers form a fairly straight line

2020-02-07T20:44:09 < Laurenceb> calling car nerdz
2020-02-07T20:44:24 < Laurenceb> what should the impedance of a diesel injectors be?
2020-02-07T20:45:43 < kakinew> check the datasheet
2020-02-07T20:45:57 < kakinew> you know
2020-02-07T20:46:03 < kakinew> those injectors have datasheets too
2020-02-07T20:46:32 < Laurenceb> wut
2020-02-07T20:46:41 < Laurenceb> searching...
2020-02-07T20:49:09 < Laurenceb> where ?
2020-02-07T20:51:07 < Laurenceb> nvm this is useful https://www.techtips.ie/Autobiz/testing-piezoelectric-injectors-1.pdf
2020-02-07T20:54:50 < kakinew> is it common rail?
2020-02-07T20:55:55 < kakinew> when you start to have injector problems in diesel car
2020-02-07T20:57:11 < kakinew> prepaire a nice stack of banknotes
2020-02-07T20:57:32 < kakinew> I mean thick
2020-02-07T20:58:17 < kakinew> luckily in my car problems with injectors have been mainly contacts loosing tension
2020-02-07T20:58:49 < kakinew> so I readjusted them with small spiky thing and plugged injectors back in
2020-02-07T20:59:20 < kakinew> what kind of problems you have lurencer?
2020-02-07T21:00:50 < Laurenceb> yeah common rail
2020-02-07T21:01:02 < Laurenceb> P1204 error on odb2
2020-02-07T21:01:34 < Laurenceb> I tested the cable back to the ecu, it has 5.1Mohm on one side and 50k on the other to gnd, same as everything else
2020-02-07T21:01:48 < Laurenceb> resistance across injector 4 is 200k, same as other injectors
2020-02-07T21:01:48 < catphish> this is pretty https://i.imgur.com/DB7rpJs.jpg can i have one?
2020-02-07T21:02:18 < Laurenceb> so I'm confused
2020-02-07T21:02:28 < Laurenceb> P1204 is injector shorted or open
2020-02-07T21:02:56 < kakinew> code?
2020-02-07T21:03:02 < kakinew> diagnosis code?
2020-02-07T21:03:05 < Laurenceb> yeah
2020-02-07T21:03:09 < catphish> Laurenceb: ongoing error? because sometimes these things happen at random
2020-02-07T21:03:12 < kakinew> check the contacts?
2020-02-07T21:03:13 < catphish> or when contacts head up
2020-02-07T21:03:16 < catphish> *heat
2020-02-07T21:03:23 < kakinew> or get loose
2020-02-07T21:03:37 < kakinew> you have car running with only 3?
2020-02-07T21:03:42 < catphish> in the first instance, clear the error, clean and reseat the connector, and see what happens
2020-02-07T21:04:40 < Laurenceb> catphish: nah its been doing it occasionally for a year
2020-02-07T21:04:49 < catphish> especially if the car is running fine
2020-02-07T21:04:57 < Laurenceb> now it fires on 3 cylinders and goes into limp mode
2020-02-07T21:05:10 < Laurenceb> yeah I tried cleaning the contacts
2020-02-07T21:05:17 < kakinew> motor is shaking like a washing machine drum?
2020-02-07T21:05:19 < Laurenceb> its just weird that impedance is 200k
2020-02-07T21:05:21 < Laurenceb> yup
2020-02-07T21:05:24 < catphish> then just replace the part and get on with your day i guess

2020-02-07T21:06:08 < Laurenceb> too expensive ree
2020-02-07T21:06:09 < kakibot> did you cross check injectors lurencebox?
2020-02-07T21:06:14 < Laurenceb> yeah
2020-02-07T21:06:18 < kakibot> all good?
2020-02-07T21:06:23 < Laurenceb> all the injectors are 200k 
2020-02-07T21:06:26 < Laurenceb> so I dunno
2020-02-07T21:06:34 < kakibot> cross check injector connectors
2020-02-07T21:06:39 < catphish> all parts can be relaced for next to no money, but if the wiring fails, fuck tgat
2020-02-07T21:06:41 < catphish> *that
2020-02-07T21:06:42 < kakibot> for displasement of contacts
2020-02-07T21:06:54 < Laurenceb> yeah I tried measuring impedance to gnd
2020-02-07T21:07:09 < Laurenceb> its the same on all the ecu connectors
2020-02-07T21:07:17 < Laurenceb> 5.1M on one side and 50k on the other
2020-02-07T21:07:26 < PaulFertser> Laurenceb: swap suspected cable with one cylinder and the suspected coil with another, and then when the error reappears you'll narrow it down.
2020-02-07T21:07:28 < catphish> unfortunately wiring can lose continuity intermittently, particularly with temperature changes :(
2020-02-07T21:07:28 < Laurenceb> so that means it has to be the injector?
2020-02-07T21:07:46 < catphish> i'd just replace the injector first
2020-02-07T21:07:54 < Laurenceb> PaulFertser: then itll fire at the wrong time surely?
2020-02-07T21:08:07 < Laurenceb> yeah I guess second hand injectors are £45 on ebay
2020-02-07T21:08:12 < PaulFertser> Laurenceb: I mean keeping the schematics, in case the wires are separate.
2020-02-07T21:08:23 < Laurenceb> do you need to scan the 2d barcode and inter into the ecu?
2020-02-07T21:08:36 < Laurenceb>  -the 2d barcode on the top of the injector
2020-02-07T21:08:40 < catphish> Laurenceb: yep, do that, 80% of the time the error code tells you what's broken, you replace it, and everything's fine
2020-02-07T21:08:47 < Laurenceb> ok cool
2020-02-07T21:08:57 < Laurenceb> hopefully I dont get a glitchy injector
2020-02-07T21:09:08 < PaulFertser> Sell yours on ebay :)
2020-02-07T21:09:12 < catphish> lol
2020-02-07T21:09:17 < Laurenceb> I was reading on forums that these siemens injectors can fail intermittently
2020-02-07T21:09:18 < Laurenceb> lol
2020-02-07T21:09:37 < kakibot> Laurenceb: check the contacts have similar tension / displacement
2020-02-07T21:09:42 < bitmask> oh yea, spot welder electrodes came, finally have all the parts
2020-02-07T21:09:51 < bitmask> hope it came with some coronavirus too
2020-02-07T21:10:19 < Laurenceb> heh new injectors are £200 wtf
2020-02-07T21:10:35 < catphish> i guess that is a pretty expensive part :(
2020-02-07T21:10:44 < catphish> but scrap parts are usually an option
2020-02-07T21:11:01 < Laurenceb> yeah, pity the mileage display isnt mechanical
2020-02-07T21:11:12 < Laurenceb> so I wont know how far each car did in the scrapyard
2020-02-07T21:11:35 < Laurenceb> is it really important to get the right torque on the injector?
2020-02-07T21:12:03 < PaulFertser> Laurenceb: I think if you just swap two of your coils it'd already be useful diagnostics.
2020-02-07T21:12:08 < catphish> fairly, borrow a torque wrench
2020-02-07T21:12:21 < Laurenceb> PaulFertser: its a diesel
2020-02-07T21:12:26 < Laurenceb> catphish: ok thanks
2020-02-07T21:12:38 < catphish> you don't want to damage your head block and not be able to replace it again in the future
2020-02-07T21:12:43 < Laurenceb> yeah
2020-02-07T21:13:15 < catphish> i'm not an expert, but i've had good luck with this kind of fix
2020-02-07T21:13:23 < catphish> (mostly sensors)
2020-02-07T21:13:31 < Laurenceb> I'll prob take it to local garage down street tbh, he can probably swap the injector for about £10 if I get everything else done myself
2020-02-07T21:13:49 < Laurenceb> thanks for the advice
2020-02-07T21:13:54 < catphish> makes sense, good luck :)
2020-02-07T21:15:17 < PaulFertser> catphish: I used spring scale with normal wrench as a poor man's substitute. It was ok.
2020-02-07T21:18:07 < Laurenceb> heh I guess I could take the eeprom out of the dashboard lol

2020-02-07T21:26:36 < englishman> Laurenceb: fyi sequential injection was only implemented in diesels ~10y ago

2020-02-07T21:48:10 < catphish> i just had to write the VIN into the dashboard to match the ECU, for some reason the immobilizer dosn't work otherwise (and fixed the mileage on it at the same time)

2020-02-07T22:20:27 < catphish> always seemed like kind of a pointless cost
2020-02-07T22:20:37 < Cracki> so they are willing to mill individual pieces of the unpressed board? neat
2020-02-07T22:21:12 < qyx> or maybe mill when the board is finished?
2020-02-07T22:21:42 < Cracki> i hope not, I don't trust them to do that perfectly
2020-02-07T22:22:45 < Cracki> hm, z-axis milling seems to imply that they'll mill the final pcb... I was thinking just mill the sheets as needed before gluing them together
2020-02-07T22:24:09 < zyp> catphish, IMO it's one of the most worthwhile upgrades I got for my car
2020-02-07T22:25:48 < Cracki> kinda like this, except not several PCBs stacked, but within the same https://hackaday.com/2019/01/18/oreo-construction-hiding-your-components-inside-the-pcb/
2020-02-07T22:27:16 < catphish> zyp: second hand performance cars tend to be a bit light on such luxuries, i guess buyers of those cars prioritize driving mods over electronics :)
2020-02-07T22:29:56 < aandrew> Cracki: sorry, was on the road. interesting, I guess that is a mild quadratic
2020-02-07T22:30:26 < Cracki> I'd buy the tencent numbers over the "official" ones
2020-02-07T22:30:40 < aandrew> catphish: I like it, it's a luxury yes, but one I'm happy to pay for
2020-02-07T22:30:44 < Cracki> why news don't label those numbers "official", but just "the numbers" is beyond me.

It was a veal meatball containing an egg yolk,  hidden and sewn into a small leaf of lettuce. "

2020-02-08T16:21:28 < grindhold> i am messing around with a bluepill [stm32f103c8t6]. i have a working usb connection that only works if an external 3.3 v power supply is attached.  according to the docs of the bluepill board there is a 5V to 3.3V converter  on board and i measure appropriate voltages at the 3.3V-pins if only usb supplies the power to the board.  is this a common issue?  does anyone have an idea how i could debug further?
2020-02-08T16:23:03 < grindhold> when i attach the board to my computer, failure mode is (according to dmesg) that the device does not accepting its setup adress

2020-02-08T16:25:59 < PaulFertser> grindhold: have you checked with example from libopencm3 that's meant to work on bluepill? It has a trick to remap usb data to gpio to pull pin low to signal host to reenumerate.

2020-02-08T16:29:04 < PaulFertser> grindhold: I'm too lazy to search for it right atm but I can tell you https://github.com/paulfertser/stm32-tx-hid works on the blue pill out of the box.

2020-02-08T16:55:02 < grindhold> that's a shame. i have to admit that i did not yet venture into replacing my laptop batteries. i always buy used laptops usually ~6 years behind current laptops. the replacement batteries for those are usually pretty cheap. and if no one does buy them, they're ultimately being thrown away, which sucks. so i end up buying replacements.

2020-02-08T23:09:26 < Steffanx> hackerspace stuff
2020-02-08T23:10:13 < Steffanx> but based on what i saw in their irc channel.. i am not too impressed.
2020-02-08T23:10:59 < mawk> is it in delft

2020-02-08T23:12:15 < Steffanx> that
2020-02-08T23:12:17 < superbia> i could visit nl
2020-02-08T23:12:32 < Steffanx> Leidschendam is where they are

2020-02-08T23:12:48 < mawk> in leidschedendam
2020-02-08T23:12:55 < mawk> I could try once
2020-02-08T23:12:57 < Steffanx> ;)
2020-02-08T23:13:41 < Steffanx> i do recall you mentioning something about their politics (in a negative way) effractur
2020-02-08T23:14:00 < mawk> politics ??
2020-02-08T23:14:06 < mawk> usually hackerspace are a leftist bunch
2020-02-08T23:14:09 < mawk> I hope not here
2020-02-08T23:14:16 < effractur> Steffanx: revspace is quite a political
2020-02-08T23:14:35 < mawk> which color of politics are they
2020-02-08T23:14:37 < effractur> maby even to a political
2020-02-08T23:14:40 < Steffanx> and they seem a big fan of vegan food. I got the feeling you're weird when you dont go vegan during their barbecue events.
2020-02-08T23:14:41 < effractur> mawk: none
2020-02-08T23:14:53 < effractur> Steffanx: na they like there meat a lot

2020-02-08T23:15:28 < qyx> hackerspaces? bitcoin++, mate++, automatic door lock ist a must, old building, 3d printer, anarchy++
2020-02-08T23:15:33 < qyx> did I forget something?
2020-02-08T23:15:52 < qyx> big LED displays too
2020-02-08T23:15:54 < mawk> you forgot long hair for dudes and colored hair for females
2020-02-08T23:16:01 < mawk> and dirty clothes
2020-02-08T23:16:09 < Steffanx> not sure about anarchy, but .. it seems very accurate qyx :D
2020-02-08T23:16:28 < qyx> they are full of cryptoanarchists
2020-02-08T23:16:46 < qyx> and antisystem thoughs
2020-02-08T23:17:16 < Steffanx> no, that cant be correct. They totally hate the "anti system" party in dutchland.
2020-02-08T23:17:25 < qyx> although anarchism itself is quite ok
2020-02-08T23:17:26 < Steffanx> They = that revspace
2020-02-08T23:17:48 < mawk> pirate party ?
2020-02-08T23:17:56 < mawk> you prefer the PVV Steffanx ???
2020-02-08T23:18:01 < Steffanx> no. The french named dude.
2020-02-08T23:18:06 < mawk> ah
2020-02-08T23:18:14 < Cracki> not sure one can call someone anarchist when they want to use the state's power to silence you
2020-02-08T23:19:10 < Cracki> btw, you can't write about monkeys in a cage, bananas, and garden hoses on youtube. those experiments are forbidden knowledge.
2020-02-08T23:19:21 < Steffanx> so #revspace it is, if you care to visit them mawk
2020-02-08T23:19:46 < qyx> whats wrong with garden hoses
2020-02-08T23:19:49 < PaulFertser> Steffanx: really vegan or going vegeterian is enough?
2020-02-08T23:20:39 < Steffanx> both. i guess
2020-02-08T23:20:48 < Steffanx> both is fine.
2020-02-08T23:21:07 < Cracki> I think a hackerspace that stocks "commercial" lemonade is probably ok
2020-02-08T23:21:22 < PaulFertser> Don't radical vegans mock not-caring-enough vegeterians?
2020-02-08T23:21:26 < BrainDamage> by mate, do you mean club-mate?
2020-02-08T23:21:32 < qyx> yes
2020-02-08T23:21:48 < BrainDamage> I tried that crap at ccc, I don't understand how can anyone like it
2020-02-08T23:21:55 < Cracki> you get used to it
2020-02-08T23:22:01 < BrainDamage> even if it has massive amount of caffeine, the taste is disgusting
2020-02-08T23:22:04 < Cracki> it's about sugar and caffeine
2020-02-08T23:22:09 < Steffanx> I dont think club mate is really a thing in dutchland either
2020-02-08T23:22:15 < Cracki> there are other flavors that aren't as disgusting
2020-02-08T23:22:43 < Steffanx> but other similar crappy drinks .. for sure.
2020-02-08T23:22:44 < englishman> tea is the best
2020-02-08T23:22:53 < Steffanx> english blend?
2020-02-08T23:23:13 < PaulFertser> oolong
2020-02-08T23:23:22 < BrainDamage> I prefer the iris blend, ceylon + hassan
2020-02-08T23:23:24 < Steffanx> or is forest fruit or lemon tea ok too?
2020-02-08T23:23:26 < BrainDamage> or pu er
2020-02-08T23:23:37 < qyx> forest fruit <3
2020-02-08T23:23:59 < BrainDamage> anything you like, however, here things that are not based off camelia synensis here are called tisane
2020-02-08T23:24:01 < BrainDamage> not tea
2020-02-08T23:24:07 < BrainDamage> to distinguish
2020-02-08T23:24:19 < BrainDamage> as in, tisane is the global cathegory, and tea is a specific subset
2020-02-08T23:24:37 < englishman> herbal tea is great too
2020-02-08T23:24:52 < Steffanx> oh, but forest fruit or lemon tea is not "tisane".
2020-02-08T23:24:57 < Steffanx> at least not here.
2020-02-08T23:25:09 < BrainDamage> if it's based of normal tea, then it's tea
2020-02-08T23:25:10 < Cracki> movement https://revspace.nl/Webcams
2020-02-08T23:25:11 < BrainDamage> lemon tea
2020-02-08T23:25:20 < Steffanx> We call it "tisane" too, if its not the real deal.
2020-02-08T23:26:27 < BrainDamage> aren't most hackerspace people quite privacy oriented? I feel like public stream of webcams goes against that idea
2020-02-08T23:26:44 < Steffanx> We should ask effractur to smile and wave to the camera the next time he is there.
2020-02-08T23:26:45 < Cracki> the more tin foil hat types don't like webcams
2020-02-08T23:26:55 < Cracki> the more technically minded ones find them interesting
2020-02-08T23:27:26 < Cracki> in the end, those who don't like to be watched in a communal space probably use it for illegal activity
2020-02-08T23:27:39 < Cracki> that shouldn't be the conclusion but it often follows from facts
2020-02-08T23:28:25 < Steffanx> where is jly when you need him. He's the tea expert.
2020-02-08T23:31:06 < superbia> Steffanx: life news?

2020-02-09T01:56:43 < Cracki> ah the milling
2020-02-09T01:56:53 < Cracki> looks like rat bite
2020-02-09T01:57:15 < Cracki> is that as they shipped it?

2020-02-09T01:59:01 < Mangy_Dog> indeed do tell us who made those
2020-02-09T01:59:04 < Cracki> are you claiming that aisler did this shoddy milling?
2020-02-09T01:59:10 < Cracki> or did you mean something else by "routing"

2020-02-09T01:59:38 < Cracki> did anyone else touch those boards
2020-02-09T02:00:58 < Mangy_Dog> kinda looks like the bit broke... or was loose in the chuck
2020-02-09T02:01:16 < Cracki> looks like someone did it by hand
2020-02-09T02:01:34 < Mangy_Dog> badly
2020-02-09T02:01:58 < Mangy_Dog> with a wood saw
2020-02-09T02:02:00 < Mangy_Dog> :D
2020-02-09T02:02:04 < Cracki> so I'm inclined to think some make:r ordered those boards from aisler, forgot to specify milling, then had to "clean" the edges himself, then sold/sent that to jadew
2020-02-09T02:02:21 < Mangy_Dog> whats aisler anyway?
2020-02-09T02:02:25 < Mangy_Dog> another pcb company?
2020-02-09T02:02:33 < Cracki> oh, it's not even jadew's domain
2020-02-09T02:02:39 < Cracki> it's some random hackaday stuff
2020-02-09T02:02:47 < Cracki> yeah some idiot fucked with those boards himself
2020-02-09T02:02:51 < Mangy_Dog> :o
2020-02-09T02:02:59 < Cracki> aisler is some NL(?) pcb people
2020-02-09T02:03:06 < Cracki> not sure if they use pooling or have their own pcb fab
2020-02-09T02:03:31 < Cracki> I don't think aisler is to blame for *that*
2020-02-09T02:03:54 < Cracki> ah, aisler is from germoney
2020-02-09T02:04:18 < Cracki> the article https://hackaday.io/project/21578-pewpew-featherwing/log/68755-boards-from-aisler

2020-02-09T02:05:30 < Mangy_Dog> ah
2020-02-09T02:05:38 < Mangy_Dog> and it was hanging for a couple weeks
2020-02-09T02:05:45 < Mangy_Dog> i suspect it was offloaded to a place in china
2020-02-09T02:05:53 < Mangy_Dog> a more dodgy place in china
2020-02-09T02:05:54 < Mangy_Dog> who knows
2020-02-09T02:06:00 < Mangy_Dog> not one of the more well known lot

2020-02-09T02:06:36 < Cracki> my boss had some dealings with aisler. apparently they're a very small shop, very few people
2020-02-09T02:06:54 < Cracki> I very much doubt that they fab PCBs. likely pooling.
2020-02-09T02:07:14 < Mangy_Dog> nods get a bulk of orders then offload to china

2020-02-09T02:11:49 < Cracki> from what I hear their "value added" is some automation, preprocessing of files
2020-02-09T02:11:51 < jadew> Cracki, yeah, they did, they said they were working it out
2020-02-09T02:11:53 < Cracki> I hear they're a ruby shop
2020-02-09T02:12:16 < jadew> I can't find any info regarding the thickness of the boards tho
2020-02-09T02:12:50 < jadew> oh, that page you linked says 1.6mm
2020-02-09T02:12:58 < jadew> sucks...
2020-02-09T02:14:14 < jadew> they're quoting me 14 eur for 3 small boards, that's not bad
2020-02-09T02:14:32 < jadew> but if I can't specify thickness they're useless

2020-02-09T02:33:13 < Cracki> nobody outside of germoney seems to know what an "imprint" is
2020-02-09T02:34:07 < jadew> because it means something different than what it appears to mean to you
2020-02-09T02:34:08 < Cracki> some offliners declared web sites to be products of the press so they have to follow the same standards
2020-02-09T02:36:16 < jadew> I gotta say... china being on vacation is quite an inconvenience
2020-02-09T02:37:32 < Cracki> how'd the local pcb fab turn out anyway
2020-02-09T02:38:04 < Cracki> they looked like they could make 1980s technology
2020-02-09T02:38:28 < jadew> I didn't contact them
2020-02-09T02:38:42 < Cracki> ^^
2020-02-09T02:39:19 < jadew> it's because I forgot about them
2020-02-09T02:39:47 < jadew> I should put them on my todo list
2020-02-09T02:40:09 < Cracki> they aren't a hot babe, only hot babes go on that list
2020-02-09T02:40:44 < Cracki> yes that was an awful pun
2020-02-09T02:41:07 < jadew> more of taunt, since it's not true
2020-02-09T02:41:23 < jadew> they go on my wish list
2020-02-09T02:42:38 < jadew> it's my birthday soon and my wife told me she's thinking of getting me something I wanted for a long time
2020-02-09T02:42:57 < jadew> and after a short break, she continues: "not another woman."
2020-02-09T02:43:12 < Cracki> it's not far off when we can have neuralink and nanobots and actually walk around like borg and casually threaten people with assimilation
2020-02-09T02:43:27 < Cracki> inb4 you get a dog
2020-02-09T02:43:33 < Cracki> or a ship

2020-02-09T02:47:05 < jadew> I want to make a tiny hotplate
2020-02-09T02:47:38 < jadew> I wonder if 150 Watts would be enough
2020-02-09T02:48:27 < BrainDamage> depends on the surface
2020-02-09T02:48:40 < jadew> that's what I was calculating now
2020-02-09T02:48:52 < Cracki> what's cooking
2020-02-09T02:49:13 < jadew> Cracki, I want to be able to remove shielding cans from boards
2020-02-09T02:49:19 < jadew> without damaging them
2020-02-09T02:49:19 < Cracki> ah yes
2020-02-09T02:49:23 < BrainDamage> 2x120W peltiers will work nicely
2020-02-09T02:49:37 < Cracki> I was meaning to order some heating element off aliex for soldering assist too
2020-02-09T02:49:50 < BrainDamage> bonus points if you drive them with H bridge you can control temp quite nicely
2020-02-09T02:50:01 < BrainDamage> and they heat up more than just the power they are rated for
2020-02-09T02:50:15 < BrainDamage> because you have the extra heat fromp the pump effect
2020-02-09T02:50:38 < Cracki> how's efficiency at around 100K difference?
2020-02-09T02:50:58 < Cracki> i.e. the heat pump part, not the "light bulb" part
2020-02-09T02:51:07 < BrainDamage> 5% or so
2020-02-09T02:51:34 < Cracki> oh right, stack them, maybe 50K each

2020-02-09T02:53:52 < invzim> in regards to how bad this dc-bias de-rating business is
2020-02-09T02:55:03 < jadew> invzim, what do you mean?
2020-02-09T02:55:29 < jadew> Cracki, I think I'll get some of these: https://www.aliexpress.com/item/32843371135.html
2020-02-09T02:56:12 < Cracki> not much area on those
2020-02-09T02:56:21 < jadew> tiny hotplate
2020-02-09T02:56:28 < invzim> well, if pretty much if you go above 3v3, you get half the capacitance or worse
2020-02-09T02:56:52 < invzim> so your 10uf is actually 5uf
2020-02-09T02:57:19 < BrainDamage> consider that electrolythic caps have +80% -20% typ
2020-02-09T02:57:32 < BrainDamage> 50% tolerance doesn't seem that bad
2020-02-09T02:57:48 < BrainDamage> or bjt that have +150% hfe, -50% ...
2020-02-09T02:58:09 < BrainDamage> most circuits work as long as you get the order of magnitude ballpark working
2020-02-09T02:58:19 < BrainDamage> just resistors that sometimes need to be accurate
2020-02-09T02:58:35 < invzim> I'm looking at new fancy dc switchers
2020-02-09T02:59:13 < invzim> anyho, the graphing stuff on sites linked above is interesting
2020-02-09T02:59:26 < invzim> dc rating seems to have about zero impact on derating
2020-02-09T02:59:47 < invzim> so a 10V drops just as fast as a 25V, other things being equal
2020-02-09T03:01:42 < invzim> s
2020-02-09T03:02:12 < invzim> space saving package, yea rite, when you also need low-esr ceramic high uF caps - https://drive.google.com/open?id=1TjOsBWDFBBW51SLkLuU88km3YTkKaPPk
2020-02-09T03:02:54 < jadew> invzim, my notes on caps say that rating drops faster for smaller packages
2020-02-09T03:03:12 < invzim> yup, that's what it looks like
2020-02-09T03:03:16 < jadew> kind of implying that it could be a function of package too
2020-02-09T03:03:24 < invzim> mostly of package I think
2020-02-09T03:03:31 < invzim> that's why the pic above has a 1210
2020-02-09T03:03:51 < invzim> (vendor recommended), even 2 of them
2020-02-09T03:10:09 < kakistage> why u-boot loads image to 0x80007fc0 and then enters kernel from 0x80008000? I don't see image header being 64bytes in size?
2020-02-09T03:10:21 < kakistage> is there some unused bytes?
2020-02-09T03:10:36 < kakistage> and it's rounded up for future additions?
2020-02-09T03:12:02 < kakistage> is the offset arbitrary?
2020-02-09T03:12:07 < kakistage> or defined?

2020-02-09T03:25:52 < kakistage> what eats?
2020-02-09T03:26:00 < kakistage> in this case
2020-02-09T03:26:04 < Cracki> read from stdin maybe?
2020-02-09T03:26:21 < Cracki> it's part of linux kernel source, so...
2020-02-09T03:26:39 < Cracki> perhaps you might want to run a linux kernel on a beaglebone
2020-02-09T03:28:11 < jadew> uhm... my math is either failing me, or I need 6 kW to heat up this hotplate
2020-02-09T03:28:39 < Cracki> afaik device trees have a textual form and a compiler exists that turns them into binary? source code?
2020-02-09T03:28:46 < kakistage> 6kW you can feel
2020-02-09T03:28:54 < Cracki> jadew, explain
2020-02-09T03:29:06 < Cracki> 6kW is two big plates
2020-02-09T03:30:05 < Cracki> tankless water heater might draw something like 10 kW
2020-02-09T03:30:32 < jadew> give me a sec, I think I was stupid
2020-02-09T03:32:23 < kakistage> yes
2020-02-09T03:32:48 < jadew> Cracki, I used an online calculator for the thermal resistance, but I think it gave me much more lower thermal resistance than it should have
2020-02-09T03:35:28 < Cracki> I'm still battling with that allegro A4955. running it at 20 khz, it needs 50% duty cycle to even start producing output. it claims to have just a microsecond of dead time for the h-bridge...
2020-02-09T03:35:35 < Cracki> same thing, calculations are off
2020-02-09T03:43:05 < jadew> thumbrule calculations are giving me different results (by two orders of magnitude)
2020-02-09T03:43:25 < jadew> and I'm inclined to believe those, because they seem more reasonable
2020-02-09T03:43:49 < jadew> I only need 40W

2020-02-09T03:57:59 < kakistage> if I intentionally crash the uboot
2020-02-09T03:58:17 < kakistage> it throws me registers and resets mcu
2020-02-09T03:58:23 < kakistage> including PC
2020-02-09T03:58:37 < kakistage> IQ++
2020-02-09T03:58:42 < kakistage> work smart they say
2020-02-09T04:07:48 < kakistage> so uboot resides about 7MB from kernel entry point 0x80008000
2020-02-09T04:07:53 < kakistage> makes sense
2020-02-09T04:08:01 < kakistage> sufficient space for kernel
2020-02-09T04:08:55 < kakistage> makes it interesting to load a whole system into ram
2020-02-09T04:09:49 < kakistage> it crashes though if I try to read the area

2020-02-09T05:39:06 < kakigate> that stuff in begin of ram is vector table ofc

2020-02-09T05:45:21 < mawk> and page tables obviously
2020-02-09T05:45:27 < mawk> they need to be somewhere
2020-02-09T05:45:56 < Cracki> that would be somewhere after 0x80000100 and before 0x80008000?
2020-02-09T05:46:11 < mawk> yes
2020-02-09T05:46:41 < Cracki> before ...100 isn't all that much. how large is the interrupt vector there?
2020-02-09T05:47:04 < Cracki> space for 64 entries, I suspect it's less used

2020-02-09T05:49:53 < kakigate> 7
2020-02-09T05:50:44 < Cracki> for some reason that looks slightly unlike a 7 to me, yet it is
2020-02-09T05:55:38 < kakigate> cortex a7
2020-02-09T05:56:15 < Cracki> a
2020-02-09T05:56:15 < kakigate> interesting thing also: a9 has just slightly more performance but a7 has critically less power consumption, die area, price etc.
2020-02-09T05:56:49 < kakigate> I imagined bigger the number the better
2020-02-09T05:59:05 < kakigate> fun how A7 is concidered little core nowdays
2020-02-09T05:59:08 < Cracki> but when it's better in every way nobody would buy it
2020-02-09T05:59:16 < Cracki> *the other one
2020-02-09T05:59:40 < kakigate> it's used as little coprocessor in stuff
2020-02-09T05:59:53 < Cracki> not sure what I would have expected but peak performance vs. best power efficiency makes sense as a trade off
2020-02-09T06:02:10 < kakigate> and there is more than bogomips too
2020-02-09T06:02:17 < kakigate> or whatever mips
2020-02-09T06:03:41 < kakigate> I bet those mips benchmarks revolve around core-cache pretty much
2020-02-09T06:05:00 < Cracki> x64 processors fight in terms of IPC (instructions per cycle)
2020-02-09T06:05:11 < Cracki> that is not just SIMD instructions

2020-02-09T17:59:19 < mawk> I think
2020-02-09T17:59:25 < mawk> use extern "C" for all these when you use weak
2020-02-09T17:59:29 < Steffanx> Did i ever say they are not good mawk? I only commented on people depending on them so much.
2020-02-09T17:59:30 < mawk> that would be my best guess if you have errors

2020-02-09T18:03:00 < mawk> you said C++ in your paste
2020-02-09T18:03:08 < mawk> if it's not C++ ignore my comments about mangling
2020-02-09T18:03:11 < kakistage> it's because there is no C option
2020-02-09T18:03:20 < kakistage> in the pastebin used
2020-02-09T18:03:24 < mawk> ah
2020-02-09T18:03:27 < mawk> so you're doing C
2020-02-09T18:03:32 < mawk> so yes it should work

2020-02-09T18:04:09 < mawk> the thing in your paste
2020-02-09T18:04:32 < mawk> but usually we do it with prototypes, then you can define the body elsewhere
2020-02-09T18:05:08 < kakistage> I dont define the body anywhere

2020-02-09T18:14:37 < mawk> you need to define the function in the same translation unit

2020-02-09T20:03:06 < qyx> https://i.imgur.com/defTVLM.png
2020-02-09T20:03:45 < qyx> there are two approaches, make ground fills around and under the pads, but make the fill hatched to lower the capacity
2020-02-09T20:03:58 < qyx> and compensate with CAPDAC inside of the capsense controller
2020-02-09T20:04:16 < kakistage> something sets CONFIG_USB_OHCI
2020-02-09T20:04:32 < kakistage> how do I know what sets it?
2020-02-09T20:04:33 < qyx> another one is to make the fills connected to AC shield output, but that makes the whole thing oscillating at 250kHz
2020-02-09T20:04:44 < qyx> and now idk which one is worse
2020-02-09T20:05:04 < kakistage> there are about 100files that have #define CONFIG_USB_OHCI
2020-02-09T20:05:28 < kakistage> only one of them should be included
2020-02-09T20:15:56 < kakistage> hmm
2020-02-09T20:16:11 < kakistage> so I had #define CONFIG_USB_OHCI
2020-02-09T20:16:27 < kakistage> and autoconf.mk had #ifdef

2020-02-10T01:20:11 < jadew> qyx, I noticed that too, let's hope that was it
2020-02-10T01:20:30 < jadew> but I bet it's going to spread
2020-02-10T01:20:52 < jadew> India had a 3 detected cases
2020-02-10T01:21:15 < Cracki> how did india get away with only 3 cases upto now
2020-02-10T01:21:24 < Cracki> it would spread like wildfire in india
2020-02-10T01:21:29 < jadew> exactly
2020-02-10T01:21:36 < jadew> they're just not detecting it
2020-02-10T01:21:54 < jadew> that's the country where swine flu is considered to be the seasonal flu
2020-02-10T01:22:21 < jadew> they're at the tip of human evolution
2020-02-10T01:23:13 < jadew> my prediction is that 2000 years from now, only indians will inhabit the earth, because they're the only nation that stayed naturally up to date with all the shittiest diseases
2020-02-10T01:25:38 < jadew> also, they're so many, it's a statistical improbability that they'll all die from... anything
2020-02-10T01:25:54 < jadew> they'll just regenerate, stronger than before
2020-02-10T01:27:14 < qyx> I also noticed that east-eu countries are free of any cases
2020-02-10T01:27:28 < qyx> I mean like at, sk, hu, cz, pl, ua
2020-02-10T01:27:31 < jadew> yeah, that's strange
2020-02-10T01:27:36 < jadew> we have chinese too
2020-02-10T01:28:32 < qyx> slovenia and croatia the same
2020-02-10T01:28:37 < qyx> idk how is it more south
2020-02-10T01:28:46 < jadew> it's possible it's already here and spreading
2020-02-10T01:29:40 < qyx> I would say you should be able to detect some unusual deaths of pneumonia and similar stuff
2020-02-10T01:29:55 < jadew> it takes up to a month for that to happen
2020-02-10T01:29:57 < jadew> it's too soon
2020-02-10T01:30:03 < qyx> maybe
2020-02-10T01:30:04 < jadew> by the time it gets detected it would be too late
2020-02-10T01:30:57 < jadew> considering it seems to double in size at every 5 days, within a month you will have thousands of cases
2020-02-10T01:31:47 < jadew> well, maybe not thousands, but anything between 50 and 4000

2020-02-10T01:40:32 < Cracki> I think the eastern european countries just have their shit together about travel control
2020-02-10T01:40:58 < Cracki> pick any country, the cases there are from chinese or ppl having had contact with chinese
2020-02-10T01:41:31 < BrainDamage> or more simply, it's less likely that chinese would visit east europe since they are poorer on average
2020-02-10T01:42:23 < jadew> yeah, that too
2020-02-10T01:43:05 < jadew> a particularly bad thing about this outbreak is that it happened during the holiday season
2020-02-10T01:43:25 < jadew> so a lot of people from china went on vacations
2020-02-10T01:43:44 < jadew> I'm very glad there's nothing to see here
2020-02-10T01:47:11 < qyx> yeah, for example we have no hub airport here
2020-02-10T01:47:28 < qyx> nor any direct flights to/from china
2020-02-10T01:48:11 < BrainDamage> during SARS outbreak the airports here had scanning IR devices to detect people with fever
2020-02-10T01:49:05 < BrainDamage> but beyond that, you cannot do much, you cannot detect people who are infected and don't display the symptoms yet

2020-02-10T05:32:16 < Cracki> identifying a frontal, upright face is an easier task than identifying a person in an arbitrary pose in some webcam picture

2020-02-10T15:35:00 < con3> Anyone know of a reliable and cheap place to do pcb assembly? Looks like jlcpcb only does small quantities as far as I can tell <30
2020-02-10T15:35:54 < specing> jlcpcb probably has the cheapest assembly if you use the components they have on the lines
2020-02-10T15:39:33 < jpa-> jlcpcb surely does larger quantities also
2020-02-10T15:40:03 < jpa-> but yeah, jlcpcb is cheap if their part selection is ok for you, seeed is a bit more expensive but can get any parts
2020-02-10T15:41:53 < con3> jpa-, just saw in the FAQ : b is cheap if their part selection is ok for you, seeed is a bit more eYou can panelize your boards to realize a quantity of more than 30 pieces, please note there is a panel size limit of not bigger than 480x320mm.
2020-02-10T15:42:06 < con3> also they only seem to do single sided assembly
2020-02-10T15:45:40 < jpa-> yeah, that limit is probably just for the basic automatically priced service, if you ask for quote i would be very surprised if they didn't do larger batches also
2020-02-10T15:46:57 < con3> jpa-, I'll have a look quick. Also thought it was weird regarding how large they are. 
2020-02-10T15:47:38 < jpa-> it would be kind of risky for the company to automatically price very large orders without manual control
2020-02-10T15:47:52 < jpa-> though jlcpcb is also funny in that larger batches sometimes cost more per unit than smaller batches :D

2020-02-10T17:52:53 < jpa-> looks like jlcpcb is operating like normal now
2020-02-10T17:53:02 < jpa-> at least my order has started production
2020-02-10T17:53:43 < kakimir> or they manually changed the status in anticipation that they can start some day in next 2 weeks
2020-02-10T17:55:07 < kakimir> invzim: would you pull 8A from qfp 0.25mm wide lead?
2020-02-10T17:55:26 < kakimir> or 0.2-0.3mm
2020-02-10T17:55:42 < kakimir> exact width will vary
2020-02-10T17:55:55 < invzim> but why such a small package for 8a
2020-02-10T17:56:10 < invzim> the caps in the reference design is n times larger than the IC

2020-02-10T17:59:15 < kakimir> board I designed had 3A buck size of 2x2mm
2020-02-10T18:00:09 < invzim> on the bright side, they have to be super-efficient with such small packages
2020-02-10T18:00:13 < kakimir> or was it 1.5x1.5mm
2020-02-10T18:00:30 < kakimir> also cost-efficient invzim
2020-02-10T18:00:37 < kakimir> no bulk of materials for no reason
2020-02-10T18:00:49 < BrainDamage> package is a decent fraction of the costs

2020-02-10T18:06:10 < invzim> got one design in "production" since early January, and another stuck in quote/negotiations as a supplier has yet to respond
2020-02-10T18:09:20 < Thorn> there are rumours that pcb & assembly factories are currently overloaded with medical equipment orders (for use within China)

2020-02-10T22:12:09 < zyp> in what sense?
2020-02-10T22:13:12 < zyp> bucks run from a common clock with a configurable phase offset per channel
2020-02-10T22:17:03 < aandrew> not how, sorry, I mean how well
2020-02-10T22:18:39 < zyp> as well as any other buck regulator, I presume

2020-02-10T22:19:38 < zyp> according to datasheet, inductors are 1uH each, which seems reasonable for the specs
2020-02-10T22:20:52 < Steffanx> 1-2 are 1. 3-4 are 2.2

2020-02-10T22:23:26 < vampirefrog> oh herro
2020-02-10T22:23:45 < Steffanx> Gooday mr vampirefrog
2020-02-10T22:23:58 < vampirefrog> good day to you sir
2020-02-10T22:24:04 < vampirefrog> and a good morrow to all
2020-02-10T22:24:26 < vampirefrog> I've figured out how to get synced I2S with the USB SOF
2020-02-10T22:24:43 < zyp> how much hair did you pull out in the process?
2020-02-10T22:25:44 < vampirefrog> I'll use a PLL to multiply the USB SOF up to 8MHz
2020-02-10T22:25:47 < Steffanx> Frogs dont have hair.
2020-02-10T22:25:49 < vampirefrog> nah not so much
2020-02-10T22:26:02 < vampirefrog> it's the best way, no compensating from software
2020-02-10T22:26:12 < zyp> ah, right
2020-02-10T22:26:12 < vampirefrog> took me a few hours to find a decent PLL
2020-02-10T22:26:26 < zyp> so have you put it together yet, or is this still just a theory? :p
2020-02-10T22:26:35 < vampirefrog> but I'll have to divide the SOF signal to half so the square wave is square
2020-02-10T22:26:45 < vampirefrog> so the comparator will be comparing two 500Hz signals
2020-02-10T22:26:57 < vampirefrog> I'm ordering the PLLs
2020-02-10T22:27:08 < vampirefrog> CD74HC4046AE
2020-02-10T22:27:26 < vampirefrog> and I'll use an internal timer of the STM32F4 to divide the output of the VCO by 8000
2020-02-10T22:27:37 < vampirefrog> or by 16000
2020-02-10T22:27:42 < vampirefrog> and possibly the USB SOF by 2
2020-02-10T22:30:05 < vampirefrog> but I'll order some dividers too
2020-02-10T22:30:20 < vampirefrog> I just don't know how to get them to divide by 8000
2020-02-10T22:30:39 < vampirefrog> guess it can be 10 * 10 * 10 * 8
2020-02-10T22:30:55 < vampirefrog> or I can get two 7-bit counters and divide by 100 * 80
2020-02-10T22:31:06 < vampirefrog> but how do I get them to reset at the right moment?
2020-02-10T22:31:12 < vampirefrog> I'd need some extra gates?
2020-02-10T22:33:14 < kakimir> md.b should do this this time it worken
2020-02-10T22:38:41 < vampirefrog> I suspect the USB SOF output is  a pulse wave
2020-02-10T22:44:03 < vampirefrog> alright so RM0090 chapter 34.7.2 describes what i'm trying to do
2020-02-10T22:44:15 < vampirefrog> 12 system clock cycles is the width of the pulse
2020-02-10T22:50:33 < qyx> external pll?
2020-02-10T22:50:56 < qyx> isn't it possible to sync MSI to SOF?

2020-02-11T00:02:18 < karlp> yar, mps has lots
2020-02-11T00:02:39 < karlp> richtek probably has too if you're going looking at the vendors, but availability is always curious.
2020-02-11T00:03:37 < zyp> I already went through richtek product range, didn't find anything that looked both good and suitable up to 24V and also were available
2020-02-11T00:03:48 < zyp> lots for lower voltages though
2020-02-11T00:04:22 < zyp> went through mps range tonight and I'm leaning towards mp8756 now
2020-02-11T00:04:53 < zyp> I don't need >24V and I don't see anything mp9447 does better

2020-02-11T00:39:46 < zyp> karlp, if they say 24V nominal, 26V max then 24V nominal should be doable
2020-02-11T00:41:04 < zyp> and if that's what my regs can do, that's what I'll claim to be able to do, and if users hook up a supply that can't keep below 26V then that's not my problem :)
2020-02-11T00:41:16 < sync> meh

2020-02-11T00:41:44 < sync> that's not a very good design, but others do that as well :/

2020-02-11T00:42:38 < zyp> well, 24V input is not the main focus of my design

2020-02-11T00:43:52 < Laurenceb> did we ask Solar Orbiter for its consent before launching it into space?
2020-02-11T00:44:28 < zyp> I should maybe consider renaming the rail, VIN is not necessarily correct
2020-02-11T00:45:27 < zyp> since there might already be a regulator feeding it
2020-02-11T00:45:52 < qyx> I named them something like vbus_lp, vbus_mp
2020-02-11T00:45:53 < zyp> e.g. a PoE setup will probably step down from 48V to 12V
2020-02-11T00:46:56 < zyp> at least the modules I got does that

2020-02-11T00:47:24 < zyp> heh
2020-02-11T00:48:19 < zyp> I've been wondering if I should put up my shit on crowdsupply or something if I ever get around to finishing the designs
2020-02-11T00:51:52 < qyx> why
2020-02-11T00:51:56 < qyx> to spread the idea?
2020-02-11T00:52:30 < zyp> to sell it
2020-02-11T00:54:06 < zyp> as far as I can tell, crowdsupply is sort of a crossover between kickstarter and a store, which is suitable because I won't be selling one product but a range of products that fit together
2020-02-11T00:54:37 < qyx> oh I though you mean a generic crowd supply
2020-02-11T00:54:50 < qyx> or how is it called
2020-02-11T00:54:55 < zyp> I mean crowdsupply.com

2020-02-11T00:55:15 < jadew> what's the advantage?

2020-02-11T00:55:42 < zyp> https://www.crowdsupply.com/domatic/getwired <- I mean, here's some sort of shit that sells a bunch of parts that fits together, where you can pick what parts to get
2020-02-11T00:56:03 < zyp> which makes sense for my shit too, since what parts you need depends on what you wanna do with it
2020-02-11T00:56:18 < zyp> jadew, advantage of what, compared to what?
2020-02-11T00:56:29 < jadew> zyp, selling them on your own online shop
2020-02-11T00:57:17 < qyx> selling on your own onlie shop is too much hassle
2020-02-11T00:57:29 < zyp> crowdfunding checks whether there's actually a market for the shit to make it worthwhile to take to production, and putting it up on a platform like that also gives marketing
2020-02-11T00:58:02 < jadew> how much are you paying them?
2020-02-11T00:58:10 < jadew> in my experience you have to do the marketing yourself

2020-02-11T01:02:40 < jadew> but I think you can obtain the same result as crowdsourcing with just preordering
2020-02-11T01:02:44 < zyp> but that only works if you already have a market that trusts you
2020-02-11T01:02:49 < Cracki> sure, electronics don't have a best-before date, but there might be a run on something and you stock up and then the run ends and you sit on stock
2020-02-11T01:03:05 < Cracki> adjust _slowly_ to sudden market demand
2020-02-11T01:03:05 < jadew> Cracki, I know
2020-02-11T01:03:18 < jadew> it seems that initial spike was just a spike
2020-02-11T01:03:26 -!- sterna [~Adium@c-a427235c.016-35-62726f1.bbcust.telenor.se] has quit [Quit: Leaving.]
2020-02-11T01:03:36 < jadew> I can't make many of these boards anyway, because they're expensive and difficult to make/test
2020-02-11T01:03:49 < jadew> so I'm not ready to take the risk
2020-02-11T01:04:27 < zyp> for the stuff I've been selling so far, I've been making a bit over 100 at a time
2020-02-11T01:05:06 < jadew> I'd make more if I had a PnP
2020-02-11T01:05:27 < jadew> but I'm currently making like... 10 or less
2020-02-11T01:05:56 < kakimir> I flashed my bootloader succesfully
2020-02-11T01:06:51 < jadew> one of the biggest issues in the assembly process seems to be from the paste dispensing process
2020-02-11T01:07:04 < zyp> yes, that's my experience too
2020-02-11T01:07:15 < jadew> I need some kind of tensor on the stencil
2020-02-11T01:07:23 < zyp> hand placing is just tedious, not hard
2020-02-11T01:07:27 < jadew> yeah
2020-02-11T01:07:31 < zyp> reflowing is easy to get good enough
2020-02-11T01:07:44 < zyp> but applying paste properly for small pads is hard
2020-02-11T01:07:58 < jadew> unless you do it at 0 °C and the oven gets confused :P
2020-02-11T01:08:17 < Cracki> my boss knows an assembly place and has them do runs of several dozens at a time. they let him have a table to do his own manual placing for prototypes
2020-02-11T01:08:25 < jadew> yeah, and you really have to clean the stencil beforehand
2020-02-11T01:08:41 < Cracki> I guess if he had the space to keep them, he'd do 100 at a time too
2020-02-11T01:09:00 < zyp> I'd love to have a PnP, but I'd have to have a lot more throughput to justify it
2020-02-11T01:09:48 < jadew> zyp, same, I figured that if it becomes a daily inconvenience, then it's time to get a PnP
2020-02-11T01:10:07 < Cracki> the time I spackled paste onto a lot of boards,... it was easy so long as that one neurotic boss would stop lecturing me about conserving paste
2020-02-11T01:10:09 < jadew> although, I'm also thinking that if I had one, I could do other stuff too
2020-02-11T01:10:21 < Cracki> paste goes much better if you have enough to spackle
2020-02-11T01:10:42 < Cracki> it doesn't go to waste either, you just want a decent amount to work with
2020-02-11T01:11:00 < jadew> Cracki, the problem is if the stencil gets lifted from the board
2020-02-11T01:11:03 < zyp> hand assembly might make sense for small numbers, getting a PnP might make sense for large numbers, but there's a big area in between where outsourcing assembly makes sense
2020-02-11T01:11:09 < Cracki> a jig to put the pcb in, one stroke across it, nice
2020-02-11T01:11:10 < jadew> then you end up squishing too much paste through it
2020-02-11T01:11:20 < Cracki> the stenci lshould be lying perfectly flat on the pcb
2020-02-11T01:11:38 < Cracki> the jig was so the pcb is surrounded by equal-height material so the stencil _can_ lie flat on it
2020-02-11T01:11:42 < jadew> zyp, I can't outsource tho... I really would like to do that, but my stuff is too easy to clone
2020-02-11T01:11:46 < Cracki> also to clamp down the stencil to the jig
2020-02-11T01:12:06 < zyp> jadew, uh
2020-02-11T01:12:18 < qyx> waht
2020-02-11T01:12:24 < zyp> giving somebody a coordinate file doesn't matter much in cloneability
2020-02-11T01:12:45 < Cracki> I always made sure the stencil was clean on the pcb-facing side and to press down well enough that there's no space between stencil and pcb for the paste to run into
2020-02-11T01:12:51 < Cracki> single pass is vital too
2020-02-11T01:12:53 < jadew> zyp, you also give them component values
2020-02-11T01:13:07 < jadew> for this thing component selection is the most difficult part
2020-02-11T01:13:11 < Cracki> multipass makes the stencil move up and down and lets paste move into spaces
2020-02-11T01:13:41 < jadew> once they know which parts to use and what values, that's it
2020-02-11T01:13:51 < invzim> put an stm32 on it
2020-02-11T01:13:55 < invzim> ROP2
2020-02-11T01:14:01 < jadew> Cracki, yep
2020-02-11T01:14:04 < invzim> for copy protection purposes
2020-02-11T01:14:09 < jadew> invzim, hehe
2020-02-11T01:14:16 < qyx> give them reels with different markings
2020-02-11T01:14:17 < invzim> I'm only half joking
2020-02-11T01:15:11 < invzim> the PSU thingie I'm tinkering with will for sure have an STM32
2020-02-11T01:15:16 < zyp> jadew, supply anonymized parts
2020-02-11T01:15:29 < jadew> zyp, without markings?
2020-02-11T01:15:49 < jadew> I thought about doing that, but I don't know how to do that
2020-02-11T01:16:15 < jadew> I can't buy in enough quantities to ask the mfg to "forget about the markings"
2020-02-11T01:16:46 < zyp> buy reel/CT/whatever, remove sticker that says what it is, put on new sticker
2020-02-11T01:16:57 < zyp> now it's as anonymous as it would be on the pcb when mounted
2020-02-11T01:17:09 < jadew> well, I scrach the markings too
2020-02-11T01:17:18 < jadew> so I'm making them more anonymous
2020-02-11T01:17:26 < zyp> better get a fiber laser as well then
2020-02-11T01:17:41 < jadew> was thinking about one of those laser engravers for this part
2020-02-11T01:17:45 < invzim> jadew: what kind of device is it?
2020-02-11T01:18:17 < jadew> invzim, it's a prescaler for HP counters
2020-02-11T01:18:46  * invzim suffers from acute coil selection trauma - wtf do everyone have their own package/footprints

2020-02-11T01:33:29 < zyp> but it is
2020-02-11T01:35:15 < zyp> I think the stuff I picked for my low voltage regs were metric 2520
2020-02-11T01:35:37 < zyp> i.e. something like this: http://www.cyntec.com/upfile/products/download/SDEM25201B-000%20(A6).pdf
2020-02-11T01:36:38 < zyp> you're probably looking at something a bit larger if you're gonna use it with that 6A rohm thing you talked about the other day
2020-02-11T01:36:47 < invzim> maybe becuase it's high amp stuff
2020-02-11T01:37:07 < invzim> man, both caps and inductors become anything but standard with this design
2020-02-11T01:37:09 < zyp> like those square 6mm things or whatever they are
2020-02-11T01:37:41 < zyp> what inductor specs do you need?
2020-02-11T01:38:04 < englishman> aandrew>	it's a zwave smoke detector "listener" -- it doesn't sense smoke, it senses the standard smoke detector alarm
2020-02-11T01:38:04 < englishman> lol

2020-02-11T01:38:14 < invzim> I haven't boned up on the math yet, but reference design is 2.2 or 4.7uh at 8+ amps
2020-02-11T01:38:45 < zyp> so which is suitable for your voltage? 2.2 or 4.7?
2020-02-11T01:39:13 < invzim> depends on switching speed
2020-02-11T01:39:37 < invzim> ref design lists one for 300khz and another for 600khz, which makes sense I guess
2020-02-11T01:39:48 < invzim> FDVE1040-H-2R2M=P3
2020-02-11T01:40:11 < invzim> the fact that digi-key doesn't have them in stock should tell me something, maybe I should re-think and use external fets
2020-02-11T01:40:21 < qyx> wat
2020-02-11T01:40:53 < qyx> just pick a random available inductor with saturation current and average current ratings you need
2020-02-11T01:41:01 < qyx> with the requested inductance
2020-02-11T01:41:15 < qyx> with reasonable dcR
2020-02-11T01:41:37 < qyx> there are some in zypsnips
2020-02-11T01:41:40 < invzim> dumb question, is current rating irreleavant as long as you're within spec or higher?

2020-02-11T01:42:17 < zyp> but there's the search I'd use to pick, I guess
2020-02-11T01:42:43 < qyx> see, 8A, uhm.. hmhm, lets say ihlp3232!
2020-02-11T01:42:43 < jadew> if you follow that link, you hijack zyp's session
2020-02-11T01:42:44 < qyx> open mouser

2020-02-11T01:43:55 < qyx> it took like 1.5 miutes
2020-02-11T01:44:15 < qyx> and cross check with the datasheet if values are okay-ish
2020-02-11T01:44:22 < zyp> yeah
2020-02-11T01:44:24 < invzim> hm
2020-02-11T01:45:08 < invzim> butbut, lcsc doesn't have it :)  Yeah I get your point
2020-02-11T01:45:14 < zyp> what I do for picking shit like this, I filter for inductance, a reasonable current range, in stock and then order for price @100
2020-02-11T01:45:23 < qyx> yeah, same here
2020-02-11T01:45:35 < qyx> also I have some favorite models
2020-02-11T01:45:51 < zyp> then I look at the top hits if there's a common package, and make a footprint that'd fit several of the top choices
2020-02-11T01:45:54 < zyp> done
2020-02-11T01:46:12 < zyp> then pick the actual one when you're doing BOM for assembly, not the layout
2020-02-11T01:47:25 < zyp> last inductor I picked was 1uH like 3A or so, metric 2520 was the obvious footprint for that
2020-02-11T01:48:11 < zyp> so I opened datasheets from two-three vendors, compared footprint recommandations and made sort of an average of those
2020-02-11T01:49:02 < zyp> and there's also limits to how much the footprint layout for a two terminal device matters :p

2020-02-11T02:17:44 < qyx> idk, I did not research high performance ones tbh
2020-02-11T02:18:51 < zyp> most cheap stuff tends to be like single or dual A7, rpi cm3+ is quad A53

2020-02-11T02:28:20 < ds2> what is a cheap one that has working power management? AFICT, none of the Pi's have PM
2020-02-11T02:28:25 < zyp> not gonna work in my B slots though, since the only OTG port is on a connector rather than headers
2020-02-11T02:29:13 < qyx> meh, it is raining

2020-02-11T04:06:33 < englishman> question for you guys
2020-02-11T04:06:48 < englishman> a competitors design uses stm32+fpga
2020-02-11T04:07:21 < englishman> the incoming signal is sampled at ~1msps >12bit and the only adc I see that is fast enough to do it is in the STM32
2020-02-11T04:07:33 < englishman> so what's the fpga for
2020-02-11T04:08:02 < englishman> or might they be sampling with stm32, sending to FPGA over some parallel interface then sending back processed data via spi
2020-02-11T04:08:17 < englishman> seems weird, why not use a standalone adc or an FPGA with adc
2020-02-11T04:08:43 < englishman> the FPGA for sure does not have adc
2020-02-11T04:10:54 < zyp> unless they ghettoed an ADC by repurposing a LVDS receiver into a comparator :p
2020-02-11T04:12:58 < Thorn> how big is the fpga

2020-02-11T04:50:55 < Thorn> anyway how much decimation can that fpga do at 1 MSPS
2020-02-11T04:51:20 < Thorn> the outgoing stream would be as much data as the incoming one
2020-02-11T04:51:29 < Thorn> so what is the point
2020-02-11T04:52:13 < Cracki> imagine more crunchy algorithms such as FFT
2020-02-11T04:52:19 < Cracki> who knows what it's doing

2020-02-11T11:28:34 < Spirit532> talk to them
2020-02-11T11:28:40 < Lux> note the break on the 0.2mm trace
2020-02-11T11:28:42 < Spirit532> I've had nothing but good quality from them
2020-02-11T11:29:05 < Lux> absolute junk and e-test should have cought that
2020-02-11T11:29:16 < Spirit532> yeah that seems wrong
2020-02-11T11:29:23 < Spirit532> they only do fab in germany or the us
2020-02-11T11:29:37 < Spirit532> e-test also couldn't test that
2020-02-11T11:29:40 < Spirit532> it looks connected
2020-02-11T11:29:42 < Lux> and it took me like 1hour to find the fault
2020-02-11T11:29:50 < Lux> no it's not
2020-02-11T11:30:02 < Spirit532> well, talk to them
2020-02-11T11:30:08 < Spirit532> they have great support
2020-02-11T11:30:25 < Spirit532> the service itself is not always perfect but support is great
2020-02-11T11:30:29 < Lux> yeah sure, but still i don't want succh a fault in the first place
2020-02-11T11:30:37 < Lux> i know their support is good
2020-02-11T11:30:39 < Spirit532> shit happens once in a while
2020-02-11T11:31:09 < Lux> it just costs time and is annoying
2020-02-11T11:31:40 < dongs> whjats wrong wiht that pic

2020-02-11T11:34:13 < dongs> oh its like etche out?
2020-02-11T11:34:17 < dongs> thinned out
2020-02-11T11:34:51 < Lux> yeah on a 0.2mm trace.. it's a full disconnect and hard to see
2020-02-11T11:35:17 < Spirit532> it looks too uniform to be just a regular defect
2020-02-11T11:35:20 < Spirit532> gerber fuckup maybe
2020-02-11T11:35:41 < dongs> i believe lux doesnt use opensores
2020-02-11T11:35:44 < dongs> so that cant be a gerber fuckup
2020-02-11T11:36:35 < Lux> 100% not
2020-02-11T11:36:49 < Lux> all the other 5 pcbs are fine

2020-02-11T11:48:19 < jpa-> con3: i've had good experience with xortech.fi also, but they have about ~500 EUR of startup costs
2020-02-11T11:48:27 < srk> con3: they do
2020-02-11T11:49:58 < dongs> people actually assemble shit with chinapcb?
2020-02-11T11:50:06 < dongs> i thikn id rather like handplace everything than send shit off to china
2020-02-11T11:50:25 < srk> we handplace for now :)
2020-02-11T11:50:26 < jpa-> dongs: why?
2020-02-11T11:50:27 < dongs> how many months is turnarond time?
2020-02-11T11:50:40 < dongs> jpa-: no idea, it seems slow, dumb, low quality and not something I wanna spend time on
2020-02-11T11:51:07 < dongs> then again i have adicknplace and do my own assembly..
2020-02-11T11:51:43 < srk> need to build one..
2020-02-11T11:52:01 < srk> or at least fix existing prototype
2020-02-11T11:52:04 < PaulFertser> srk: or just order assembly from your friend dongs :)
2020-02-11T11:52:10 < srk> :D
2020-02-11T11:52:36 < srk> there's a local guy that does assembly with some cheapo chinese pnp
2020-02-11T11:52:37 < srk> without vision
2020-02-11T11:53:08 < PaulFertser> srk: yesterday I digged xmobar and I had a thought crossing my mind that Haskell is probably not for me or not for tasks like that :/
2020-02-11T11:53:25 < con3> well i mean if their gonna make the pcb and can assemble aswell, why not
2020-02-11T11:53:45 < srk> PaulFertser: xmobar is cool, I've switched to it from dzen like two years ago
2020-02-11T11:53:51 < srk> PaulFertser: also xmonad is great :)
2020-02-11T11:55:39 < PaulFertser> srk: inorite https://​gitorious.org/xmonad-smartphone-config/xmonad-smartphone-config/
2020-02-11T11:55:53 < srk> haha
2020-02-11T11:56:50 < PaulFertser> srk: I was actually daily using it till I teared the resistive touchscreen flex cable :/
2020-02-11T11:57:46 < srk> PaulFertser: xmonad with touchscreen?
2020-02-11T11:58:20 < srk> yesterday one my coolermasta keyboards stopped working, just like that
2020-02-11T11:58:24 < srk> time to build my own I guess
2020-02-11T11:58:27 < PaulFertser> srk: yep, that device has just two hardware buttons. So I used one to trigger on screen keyboard, and another for suspend-to-ram.
2020-02-11T11:58:38 < srk> aah :)
2020-02-11T11:58:53 < PaulFertser> srk: btw, xmobar sucks, it doesn't have nl80211 support for wireless, I'm probably trying to fix that.
2020-02-11T11:59:26 < srk> I see
2020-02-11T11:59:49 < srk> I do use network-manager on notebooks (with stalonetray)
2020-02-11T12:00:29 < PaulFertser> srk: http://paste.debian.net/1130136/ works but it's silly because it's getScanResults filtered under the hood.
2020-02-11T12:00:50 < PaulFertser> srk: no need for network-manager here, I use wpa_supplicant directly.
2020-02-11T12:01:01 < dongs> why that site fails SSL
2020-02-11T12:01:11 < PaulFertser> dongs: because it's webarchive
2020-02-11T12:01:18 < PaulFertser> dongs: gitorious was closed few years ago
2020-02-11T12:01:34 < dongs> oh i see t he dates
2020-02-11T12:01:34 < dongs> 2013
2020-02-11T12:01:43 < dongs> why is the server still up then

2020-02-11T12:02:25 < srk> PaulFertser: will take a look later, had to close browser to make some ram available for compiling :D
2020-02-11T12:02:35 < dongs> fucking lunix lmao
2020-02-11T12:02:36 < PaulFertser> srk: are you using noscript?
2020-02-11T12:02:39 < srk> yep
2020-02-11T12:02:51 < dongs> do you have like 1gb ram or something
2020-02-11T12:02:52 < srk> but 2k+ tabs will kill firefox anyway 
2020-02-11T12:03:06 < srk> I need indexing and autoclosing of tabs
2020-02-11T12:03:17 < dongs> i disabled tabbed shit in chrome
2020-02-11T12:03:19 < srk> dongs: 16 and had to enable swap recently ;(
2020-02-11T12:03:26 < dongs> and i have an extension that closes a window i havent  touched for >2 4hours
2020-02-11T12:04:19 < srk> yeah, need something like that as well but with full text indexing 
2020-02-11T12:04:43 < dongs> i dont understand the point of having more than 10-something windows open
2020-02-11T12:04:44 < BrainDamage> of the web page content?
2020-02-11T12:04:45 < srk> so I can find the stuff later without digging in my brains memory
2020-02-11T12:04:48 < dongs> it becomes impossible to navigate

2020-02-11T12:06:05 < sync> dongs: having the tabs for later reference is nice
2020-02-11T12:06:13 < dongs>  what lter reference?
2020-02-11T12:06:21 < dongs> why not save the pdf or whatever locally
2020-02-11T12:06:32 < sync> because then it's not in my browser

2020-02-11T12:08:05 < srk> and disable blue in my term
2020-02-11T12:08:21 < BrainDamage> this forces me to copy it over and classify it
2020-02-11T12:08:33 < BrainDamage> if I genuinely care
2020-02-11T12:08:40 < PaulFertser> I just open all the tabs in private mode. Then when the browser crashes I think "ok, guess I really didn't need any of those".
2020-02-11T12:09:00 < dongs> so basically you didnt need it in the first place
2020-02-11T12:09:01 < dongs> got it.
2020-02-11T12:09:19 < PaulFertser> Yeah, I'm doing only useless things

2020-02-11T14:55:58 < karlp> there's a whole slew of connector options that are better than soldering wires to boards.
2020-02-11T14:56:02 < englishman> yep
2020-02-11T14:56:32 < karlp> ah well, at least it's a circus, not an abandonded lot?
2020-02-11T14:56:49 < englishman> though there are production issues with crimps as well, the pcb is rather tight and there isn't a lot of room in the enclosure, we use a custom cable at a bunch of different lengths so precrimping adds a lot of part numbers and effort etc, punchdowns save on that

2020-02-11T22:31:17 < zyp> Cracki, on the carrier board I'm designing
2020-02-11T22:31:21 < Cracki> ic
2020-02-11T22:32:20 < Cracki> can it do displayport? dp to ethernet (vnc or whatever)?
2020-02-11T22:32:39 < qyx> wat
2020-02-11T22:33:28 < zyp> https://bin.jvnv.net/file/aPbP3.png <- I added the sd socket earlier, so now it's just missing hookup of a few gpios and routing and then it should be good to go
2020-02-11T22:33:36 < Cracki> no need to attach a real display or even a cable
2020-02-11T22:35:37 < zyp> I'm not really planning to use HDMI for any of my stuff, but the signals are there and I have available space to fit a connector, so the total cost is probably not that many cents
2020-02-11T22:36:44 < qyx> Cracki: whats the role of the dp in this setup?
2020-02-11T22:36:55 < qyx> you can du vnc over ethernet without dp of any kind
2020-02-11T22:36:59 < qyx> lol du
2020-02-11T22:37:06 < Cracki> no idea, *something* that catches the signal and acts like an ipmi/ilo/kvm
2020-02-11T22:37:40 < qyx> just run x11vnc or how is it called
2020-02-11T22:37:46 < qyx> instead of xserver
2020-02-11T22:38:01 < qyx> it hosts a full graphical session inside a vnc server
2020-02-11T22:38:12 < Cracki> I guess I should illustrate the purpose of having this in hardware

2020-02-11T22:38:27 < Cracki> do you know what an ipmi or ilo does, qyx?
2020-02-11T22:38:31 < qyx> yes
2020-02-11T22:38:32 < Cracki> heh
2020-02-11T22:39:28 < zyp> anyway, the next inevitable question; what's everybody's favorite hdmi socket? :p
2020-02-11T22:39:56 < zyp> I suspect there might be a standard footprint for that, or are there a ton to choose from?
2020-02-11T22:41:31 < zyp> I'm not really interested in doing micro-hdmi, it's always a pain finding a cable for that when you need one
2020-02-11T22:49:39 < karlp> who's going to buy this and send it to me? https://www.koupelny-sen.cz/liv-195851

2020-02-11T22:53:07 < zyp> apparently it's a toilet flush button
2020-02-11T22:53:25 < jadew> that costs 25 Eur
2020-02-11T22:53:28 < zyp> so I'm guessing karlp broke his, and identical ones are not sold in iceland anymore
2020-02-11T22:53:35 < karlp> no idea yet if they will ship it to iceland.
2020-02-11T22:53:53 < karlp> run into enough problems with local retailers like this before.
2020-02-11T22:54:16 < karlp> I have a .cz warehouse worst comes to worse, but have emailed a bunch of the stores here to see if they know who does/did sell it.
2020-02-11T22:54:36 < karlp> found it for sale in .hr as well,
2020-02-11T22:56:09 < jadew> well, if you're going to ship it to someone in the EU, it will end up costing you at least 70 eur total
2020-02-11T22:56:22 < jadew> you're better off buying a new toilet
2020-02-11T22:56:30 < zyp> no, he's not
2020-02-11T22:56:34  * karlp laughs
2020-02-11T22:56:39 < zyp> this is for a wall-embedded cistern
2020-02-11T22:56:46 < karlp> you think Ic an get a new inwall toilet for a less than 70euro?!
2020-02-11T22:56:54 < karlp> _installed_ ?
2020-02-11T22:56:56  * karlp laughs
2020-02-11T22:56:56 < zyp> tearing open the wall, replacing it and re-waterproofing the wall is fucking expensive
2020-02-11T22:57:28 < jadew> I think it's time we introduce tags
2020-02-11T22:57:29 < karlp> still not sure why it should go from 25 to 70 euro 
2020-02-11T22:57:30 < jadew> @joke
2020-02-11T22:57:41 < qyx> karlp: no shipping to .is, only .sk/.cz
2020-02-11T22:57:57 < jadew> karlp, well shipping to a different country (unless you find someone in the country with the shop)
2020-02-11T22:58:07 < jadew> then shipping to you
2020-02-11T22:58:19 < karlp> qyx: ok, thanks for reading fast for me.  I can get it shupped to .cz with tiptrans, and they'v ebeen pretty cheap so far for shipping onwards.
2020-02-11T22:58:36 < qyx> to .sk it would be 25e the button itself, 10e shipping
2020-02-11T22:58:46 < qyx> I'll check shipping to .is

2020-02-11T22:59:05 < karlp> that's all fine.
2020-02-11T22:59:23 < jadew> 15 eur would be good
2020-02-11T22:59:32 < karlp> if I could even buy it for less than 60eur locally i'd be very happy.
2020-02-11T22:59:36 < jadew> I'm paying 20+ for shipping outside of the EU
2020-02-11T22:59:47 < karlp> I think tiptrans gets better rates than you do.
2020-02-11T23:00:52 < qyx> karlp: 7.50e shipping to iceland
2020-02-11T23:01:00 < qyx> by classic post, 3-8 days
2020-02-11T23:01:13 < jadew> man... we are getting ripped off
2020-02-11T23:01:15 < karlp> see, no problem.
2020-02-11T23:01:16 < zyp> karlp, but do you really need an identical one?
2020-02-11T23:01:27 < karlp> no, but that's the one I've found that matches, that's not even the one we had :)
2020-02-11T23:01:43 < karlp> I've already been to the local stores, they arrangement of the poker rods is apparently not standardized at all.
2020-02-11T23:01:59 < karlp> vendor lists the compatibility: http://en.liv.si/products/flushing-plates/
2020-02-11T23:02:38 < zyp> ah
2020-02-11T23:03:56 < karlp> if I take enough measurements, and they let me open enough boxes, I _might_ be able to find a match locally. but it looks like I can get a "known to match" part for not crazy prices.

2020-02-11T23:26:25 < Steffanx> With display for something?
2020-02-11T23:26:50 < Steffanx> not sure why that is relevant, but i recall that is what zyp wanted back in the time.
2020-02-11T23:26:52 < BrainDamage> no idea about display, I've only seen it powered off
2020-02-11T23:27:01 < BrainDamage> and ate the things it made
2020-02-11T23:27:32 < zyp> they come with either mechanical or electronic timer
2020-02-11T23:27:52 < zyp> I wanted the latter, norwegian stores only had the former at the time
2020-02-11T23:29:00 < Steffanx> Is it easy to keep that thing clean?
2020-02-11T23:29:46 < zyp> I throw it in the dishwasher now and then
2020-02-11T23:32:57 < Steffanx> ohno, there goes the non-stick coating?

2020-02-11T23:34:03 < zyp> uh
2020-02-11T23:34:18 < zyp> does it even have teflon coating?
2020-02-11T23:34:22 < BrainDamage> non stick coating survives dishwasher fine?
2020-02-11T23:34:29 < zyp> also, does teflon have a problem with dishwashers?
2020-02-11T23:34:48 < zyp> I wash teflon pans in the dishwasher all the time
2020-02-11T23:35:05 < BrainDamage> the main problem is mechanical abrasion, not hot water sprayed on
2020-02-11T23:35:16 < BrainDamage> otherwise it wouldn't even be safe for cooking
2020-02-11T23:36:09 < BrainDamage> it also emits toxic fumes if overheated, but good luck getting a dishwasher heated to 300°C

2020-02-12T03:40:35 < jadew> Cracki, you might not be
2020-02-12T03:40:47 < jadew> if you're a repair shop, you might even be wearing gloves
2020-02-12T03:40:57 < Cracki> always repair naked
2020-02-12T03:41:41 < Cracki> if I'm wearing gloves, those isolate against esd don't they
2020-02-12T03:41:50 < Cracki> so it shouldn't matter how charged I am
2020-02-12T03:43:09 < jadew> true I guess
2020-02-12T03:43:41 < jadew> so why spend so much on covering your benches with ESD mats, when all you need is a $2 bracelet?
2020-02-12T03:49:26 < Cracki> bracelets are for slaves :>
2020-02-12T03:49:45 < Cracki> personal preference ¯\_(ツ)_/¯

2020-02-12T04:18:39 < sync> jadew: but your twerk surface can hold a charge
2020-02-12T04:19:17 < jadew> yeah, but if you have a bracelet you're fine
2020-02-12T04:19:25 < jadew> and not all of them do hold a charge
2020-02-12T04:19:40 < Laurenceb> https://www.youtube.com/watch?v=s1yeBmSFkC4
2020-02-12T04:20:10 < sync> how does your bracelet ground your work surface?
2020-02-12T04:20:28 < jadew> ah, that's what you meant by twerk surface
2020-02-12T04:20:47 < jadew> I don't think it holds a charge tho...
2020-02-12T04:21:01 < sync> that's where you are in the wrong
2020-02-12T04:21:11 < jadew> I mean... what could you do to charge it up so much
2020-02-12T04:21:24 < jadew> and most importantly, would it even discharge?
2020-02-12T04:21:40 < jadew> because it will only discharge at the contact point, not being conductive like the human body
2020-02-12T04:21:47 < sync> if you are grounded and hold something against it, most likely

2020-02-12T04:22:37 < jadew> the only cases of ESD damage that I witnessed myself, were caused by me, not by the bench
2020-02-12T04:23:15 < jadew> you'd have to scrub it in anger to generate enough static electricity for it to become dangerous
2020-02-12T04:24:06 < sync> well, it also depends on how far you are trying to eliminate the risk
2020-02-12T04:24:21 < sync> I like my esd mat because it is also heat resistant
2020-02-12T04:24:27 < jadew> I actually think the risk is minimal
2020-02-12T04:24:34 < jadew> yeah, that's the only reason I like mine
2020-02-12T04:25:04 < sync> well, I'd like to see you argue that to a judge when your product was responsible for the death of a bunch of people
2020-02-12T04:25:20 < jadew> heh
2020-02-12T04:26:05 < jadew> seriously tho, has anyone here ever seen a bench discharge itself?
2020-02-12T04:26:25 < jadew> because if nobody has, then it must be BS
2020-02-12T04:26:37 < Cracki> define "bench discharging itself"
2020-02-12T04:26:41 < jadew> spark
2020-02-12T04:26:42 < Cracki> a grounded work surface?
2020-02-12T04:26:50 < jadew> I want to see a spark
2020-02-12T04:26:53 < Cracki> or a discharge zapping something
2020-02-12T04:27:08 < jadew> I've seen them coming out of me, so I know it's possible
2020-02-12T04:27:19 < jadew> unless I see a bench doing the same thing, I call BS
2020-02-12T04:27:50 < Cracki> if I charge myself while holding a pcb or IC, and then touch that ic to a low-impedance grounded thing, that zaps
2020-02-12T04:28:11 < Cracki> anything made from wood is hard to charge
2020-02-12T04:28:16 < jadew> the biggest difference between a bench and the human body is that even if a bench has the same charge as you do, it can't discharge it all through a single point, because it's not conductive
2020-02-12T04:28:23 < sync> I held a static field meter to a few benches at work and it showed a few kv
2020-02-12T04:28:23 < Cracki> wood is an ideal surface to discharge slowly against
2020-02-12T04:28:40 < jadew> sync, sure, but could you discharge that or fry anything with it?
2020-02-12T04:28:42 < jadew> I think not
2020-02-12T04:28:54 < sync> no, but the guy that will put me in jail will also walk around with a fieldmeter
2020-02-12T04:28:57 < jadew> Cracki, yeah I think wood is good that way
2020-02-12T04:29:31 < sync> or rather I cannot be sure that it does not
2020-02-12T04:29:48 < sync> for most purposes it probably does not matter, but why take the risk?
2020-02-12T04:29:49 < Cracki> when they use that spinning thing to charge up little kids with long hair in class, they're told to touch the wood paneling afterwards
2020-02-12T04:29:59 < Cracki> ground all the things
2020-02-12T04:31:07 < jadew> you know what's funny? all the ESD related damages I've provoked, were on top of an ESD mat
2020-02-12T04:31:26 < jadew> probably because this is where I work the most
2020-02-12T04:32:26 < Cracki> most people are shot near guns
2020-02-12T04:32:33 < sync> well, is your floor ESD dissipative? are you wearing ESD slippers and did you wear your bracelet?
2020-02-12T04:33:56 < jadew> I have a wooden floor and I go barefoot
2020-02-12T04:34:06 < jadew> and I also wear an ESD bracelet now
2020-02-12T04:34:46 < sync> yeah wooden floors are relatively ok
2020-02-12T04:36:40 < sync> but yes, in general it's not too much of an issue

2020-02-12T14:17:24 < jadew> what an unrealistic movie...
2020-02-12T14:17:53 < jadew> someone knocks at the door in the middle of the night, and guess what... the wife wakes up, while the husband sleeps like a rock
2020-02-12T14:19:30 < jadew> I heard a noise one night (something fell off of the wall in the bathroom), and I think in one second I was up, fully awake and my mind was instantly filled with all the possible break-in scenarios
2020-02-12T14:20:07 < jadew> my wife got startled by my reaction and was looking at me from a semi-sleep
2020-02-12T14:22:12 < jadew> new updates on corona virus: "Package arrived in destination country - AliExpress"
2020-02-12T14:23:40 < jadew> I'm gonna pause the movie, who wants to guess if the wife is going to get murdered once she opens the door?
2020-02-12T14:25:19 < jadew> there are 3 possibilities here: 1) She gets murdered right after she opens the door. 2) She gets murdered together with the unresponsive husband, after whoever is at the door forces their way in. 3) She gets murdered through the door, after she says "who is it?".
2020-02-12T14:27:04 < jadew> this is minute 3:33 of the movie, so the story has plenty of time to develop in any direction
2020-02-12T14:29:16 < jadew> second question: Who was at the door?
2020-02-12T14:29:38 < jadew> 1) A known person. 2) A stranger. 3) A car.

2020-02-12T14:57:46 < jadew> very stable currency. people should get loans in BTC
2020-02-12T15:05:00 < zyp> if I want a cheap windows-capable tablet that charges via usb-c, what options do I have?
2020-02-12T15:05:09 < zyp> emphasis on cheap
2020-02-12T15:06:56 < zyp> requirements are simple; run windows, usb-c port for charging, usb-a port to connect shit
2020-02-12T15:07:33 < Thorn> ugh are there tablets with type A ports at all? (or multiple usb ports)
2020-02-12T15:07:48 < Thorn> there're laptops with detachable keyboards iirc
2020-02-12T15:08:10 < Thorn> (but the connectors may well be in the keyboard part)
2020-02-12T15:08:45 < zyp> lots
2020-02-12T15:14:14 < karlp> why usb-c for charging?
2020-02-12T15:14:25 < karlp> I mean, nice, but why a requirement?
2020-02-12T15:16:04 < zyp> so I don't need a special charger for it
2020-02-12T15:16:57 < karlp> presumably it would come with one itself? 
2020-02-12T15:18:34 < zyp> sure
2020-02-12T15:19:04 < zyp> but that doesn't plug into usb-c powerbanks or car chargers
2020-02-12T15:22:55 < zyp> I'm thinking about getting something convenient to run VCDS, so being able to power it easily in the car is relevant
2020-02-12T15:25:07 < zyp> at the moment the newest portable windows device I've got is a ten year old laptop, and neither the ten year old battery nor the proprietary charger it came with is very convenient to use in the car
2020-02-12T15:26:46 < zyp> and since there's not really much need for a keyboard, a windows tablet seems a lot more suitable

2020-02-12T17:55:26 < kakimir> do you have boiler plate code posix program that will input and output from pipe
2020-02-12T17:56:32 < kakimir> sorry.. only input
2020-02-12T17:57:21 < kakimir> like cat blob.bin | myspecialdecoder
2020-02-12T17:57:38 < kakimir> outputs parse to terminal
2020-02-12T17:57:49 < kakimir> like cat blob.bin | myspecialdecoder > parse.txt
2020-02-12T17:57:57 < kakimir> then it's in a file
2020-02-12T17:58:51 < Ultrasauce> fopen(stdin)..

2020-02-12T18:19:04 < kakimir> know to terminate when cat blob.bin returns?
2020-02-12T18:19:23 < kakimir> wait..
2020-02-12T18:19:45 < kakimir> only cat returns?
2020-02-12T18:20:04 < kakimir> everything down the chain is just killed?
2020-02-12T18:23:36 < kakimir> stdin closes and that ends the program?
2020-02-12T18:26:05 < karlp> no, you're just expected to handle the eof properly.
2020-02-12T18:26:52 < kakimir> what if the input is binary?
2020-02-12T18:27:03 < kakimir> just arbitrary values
2020-02-12T18:27:09 < kakimir> *bytes
2020-02-12T18:27:44 < kakimir> isn't eof just a char?
2020-02-12T18:28:29 < kakimir> so input should not maybe be binary?
2020-02-12T18:28:43 < doomba> so here's what i came up with for dma usart http://dpaste.com/35P129T
2020-02-12T18:28:46 < doomba> works gr8
2020-02-12T18:28:55 < kakimir> and I should rather read the file directly with fopen instead of cat binary.bin | ?

2020-02-12T18:35:22 < karlp> doomba: first step in adapting to g0 would be replacing /f1/nvic.h with /nvic.h and using the dispatch headers properly .)
2020-02-12T18:35:37 < karlp> but f1 is like the _least_ compatible with g0 you could find :)
2020-02-12T18:36:18 < doomba> karlp: haha yes i know. i used f1 because i had these blue pills laying around and it was easier to develop the concept with it instead of on the g0 because the uart on the g0 shares the same pins as swd.

2020-02-12T23:50:53 < englishman> because it reuses the register for period

2020-02-13T03:44:19 < aandrew> is that everyone coming back from CNY
2020-02-13T03:45:03 < jadew> it looks like so far more people have died of this thing than of SARS
2020-02-13T03:45:24 < jadew> in 1/6 of the time
2020-02-13T03:45:54 < aandrew> yes it seems to be far more deadly although it seems that it's not because the bug is deadly but rather the sheer number of people needing treatment is overwhelming the resources available
2020-02-13T03:46:06 < jadew> yeah, it's much more infectious
2020-02-13T03:46:22 < aandrew> it *seems* like if you're diagnosed and can support your lungs while your body fights it you're fine
2020-02-13T03:46:28 < aandrew> it's not that much more IIRC
2020-02-13T03:46:38 < jadew> yeah, that's what I understand too
2020-02-13T03:46:50 < jadew> but that requires oxygen
2020-02-13T03:47:04 < aandrew> actually lower
2020-02-13T03:47:15 < aandrew> r0 of SARS was 3, this seems to be 1.4-4
2020-02-13T03:47:20 < aandrew> hasn't been nailed down yet

2020-02-13T03:48:01 < jadew> uhm... if it's lower, how come more people have been infected a lot faster?

2020-02-13T13:03:57 < qyx> which should lower the numbers
2020-02-13T13:04:38 < qyx> or am I wrong
2020-02-13T13:04:57 < zyp> if I read it right, they are now counting cases that are only diagnosed with lung xray, not chemical tests
2020-02-13T13:05:11 < zyp> or something like that
2020-02-13T13:05:59 < qyx> so they count any pneumonia cases including those not cause by nCoV
2020-02-13T13:07:13 < qyx> also, any counting method should not change number of deaths

2020-02-13T15:19:00 < karlp> I've already manually visted the url endpoint and accepted the exception
2020-02-13T15:19:05 < jadew> I thought you had problems with SSL, and you needed a solution for testing purposes
2020-02-13T15:19:10 < karlp> it just goes, "oh, doing a cors preflight, nah, going to ignore that"
2020-02-13T15:19:20 < karlp> so it doesn't even make the cors preflight.
2020-02-13T15:19:41 < aandrew> jadew: a recovery. london, ontario
2020-02-13T15:19:51 < aandrew> 4 infections in vancouver, 2 in toronto
2020-02-13T15:19:53 < jadew> antto, another one in Finland
2020-02-13T15:21:34 < karlp> chromium accepts it, firefox won't, so that will do for testing.  final endpoitn has a proper cert anyway
2020-02-13T15:21:55 < karlp> though, at _presnt_ the final endpint (a third party) doesn't do any CORS handling, so it doens't work _anyway_
2020-02-13T15:22:15 < karlp> shelling to curl on the server instead of an xhr is looking way more appealing than working around cors bullshit

2020-02-13T15:57:19 < zyp> haha
2020-02-13T16:02:55 < karlp> and I've  just had to fix the js xhr library provided to be able to make a post with both url params and data body. joy
2020-02-13T16:02:55 < zyp> karlp, so what's the problem anyway? the way you describe it it sounds more like a TLS issue than a CORS issue
2020-02-13T16:03:34 < karlp> firefox won't even make the cors options request to the slef signed server, even if you've accepted it as a security exception
2020-02-13T16:03:49 < karlp> _that_ only affects me on a self signed test server.
2020-02-13T16:04:20 < zyp> yeah, that doesn't sound like CORS at all, that sounds like TLS cert exceptions don't apply to XHR
2020-02-13T16:04:37 < karlp> which is a) not what the firefox message says, and b) dumb.
2020-02-13T16:04:46 < karlp> but hey, it's the modern web, clever never entered it.

2020-02-13T16:06:10 < rajkosto> AND THE WEB IS SECURE AGAIN
2020-02-13T16:06:21 < zyp> so XHR with text/plain works even with a cert exception?
2020-02-13T16:07:15 < zyp> if so that sounds like dumb corner case handling between cert exceptions and CORS
2020-02-13T16:08:08 < zyp> simple solutions: fuck testing with self signed certs
2020-02-13T16:08:45 < rajkosto> get a freebie from letsencrypt its real easy
2020-02-13T16:08:49 < karlp> no, xhr withtext/plain doesn't trigger a cors preflight check, it then triggers the _normal_ exception paths, and works.
2020-02-13T16:09:11 < zyp> I'd either run the apiserver unencrypted or with let's encrypt
2020-02-13T16:09:24 < karlp> well, it's not my api server :)
2020-02-13T16:09:46 < zyp> then it's not your problem either, tell the dumb fucks to fix their shit
2020-02-13T16:09:49 < karlp> the real one has a cert, but doesn't (yet) provide any cors responses, so it's still not actually usable, because of cors itself.
2020-02-13T16:10:07 < karlp> but I still wanted to test locally, so I had a self signed, with cors.
2020-02-13T16:10:15 < karlp> and that now works in chromium, but not firefox.
2020-02-13T16:10:53 < zyp> or throw up a proxy shit that does proper handling on the frontend side and ignores error on the backend side
2020-02-13T16:11:54 < zyp> e.g. start a traefik instance with a few lines of config to do that, shouldn't take many minutes to get running
2020-02-13T16:18:39 < zyp> https://docs.traefik.io/routing/services/#servers https://docs.traefik.io/routing/overview/#insecureskipverify https://docs.traefik.io/https/acme/ https://docs.traefik.io/middlewares/headers/#cors-headers
2020-02-13T16:18:57 < zyp> there's the config lines you need, slap them in a file, start traefik, done
2020-02-13T16:21:30 < karlp> I'm not running another server for test, for test chromium was sufficient, fuck firefox.  for production, the third party just _will_ fix their server to include cors, no fucking way am I going to permanently run an api front for them.

2020-02-13T16:31:47 < zyp> it's just so simple to get proper certs now that it's kinda dumb to waste time dealing with invalid certs

2020-02-13T16:35:08 < zyp> I've got traefik running in my docker setup here, doing TLS termination, let's encrypt and hostname to service mapping, so all I have to do to set up a new service with proper https on it's own hostname is tag the container with a couple of labels
2020-02-13T16:41:57 < karlp> you want me to setup lets encrypt certs on.... some domain.... for my laptop, just because firefox is being a dick? I don't really get that.
2020-02-13T16:42:21 < karlp> setting up a cloud server just so that I can get tls nicely, again, because firefox is a dick?

2020-02-13T17:40:34 < zyp> a couple of weeks ago I was looking at setting up some wiki shit for documentation, it took me this much of config to bring up an instance of wiki.js: https://paste.jvnv.net/view/E9AM0, accessible at https://wiki.home.zyp.no/ with proper TLS

2020-02-13T17:42:15 < zyp> I'm a proponent of spending a bit more time upfront to save time in the long run
2020-02-13T17:42:16 < karlp> well, again, this was _only_ a problem, because _firefox_ doesn't respect it's security exceptions when it does cors preflight checks.
2020-02-13T17:42:45 < karlp> at no point in that would I have gone, "you know what, setting up docker infrastructure to make tls endpoints is how I'm going to solve this"
2020-02-13T17:44:06 < zyp> if this is the only point ever you're gonna make a tls endpoint, I can agree with you
2020-02-13T17:45:58 < zyp> but why even do tls at all if you're not gonna do it properly?
2020-02-13T17:46:17 < karlp> well, I _made_ my own tls endpoint, and I _could_ hve setup dns on it if I really wanted, but it's all internal, and was just mocking something, so I didn't see why I couldn't just use a self signed cert.
2020-02-13T17:46:43 < karlp> basically, I'm just getting told, again, that you're not allowed to run services as a peon anymore
2020-02-13T17:47:12 < BrainDamage> browsers hate self signed certs, they think that people will see https and will assume secure
2020-02-13T17:47:23 < BrainDamage> therefore fat warning, hard to circumvent, etc
2020-02-13T17:47:25 < karlp> (there's a years old bug on this in firefox, and tehy've wontfixed it anyway)
2020-02-13T17:47:41 < karlp> BrainDamage: yeah, but I _accepted_ the exception, I don't want to do this in production.
2020-02-13T17:47:55 < karlp> production _has_ a proper cert, bought and paid for.
2020-02-13T17:49:33 < zyp> why not just make it a http endpoint for local testing?
2020-02-13T17:49:43 < zyp> or is that also disallowed these days?
2020-02-13T17:49:54 < karlp> mixed-content problems then,
2020-02-13T17:50:10 < karlp> but yeah, tried that too, but other rabbit holes :)
2020-02-13T17:50:12 < zyp> not if you put it all on http
2020-02-13T17:50:33 < karlp> it's finished, I just used chrome :)
2020-02-13T17:50:47 < karlp> I've learnt more about how cors is implemented behind the scenes. yay me.
2020-02-13T17:51:20 < srk> who's paying for certs in 2020
2020-02-13T17:51:44 < karlp> people who need to provide them to someone else and only for a portion of the domain.
2020-02-13T17:51:54 < srk> pros xD
2020-02-13T17:52:19 < karlp> well, how would you give company XXX a cert for blah.mycompany.com ?
2020-02-13T17:52:29 < srk> you won't
2020-02-13T17:52:39 < karlp> ok thenm, good answer.
2020-02-13T17:52:45 < srk> no need to, you can use letsencrypt on demand
2020-02-13T17:52:45 < zyp> I could see paying for an EV cert, but plain ones are not really worth paying for anymore when they can be had for free
2020-02-13T17:52:46 < karlp> because buying that cert works.
2020-02-13T17:54:34 < zyp> karlp, if you can demonstrate control of blah.mycompany.com, letsencrypt gives you a valid cert for it, automatically, for free

2020-02-13T17:56:05 < Ultrasauce> for some internal use cases like testing it works well to add your own root cert also
2020-02-13T17:56:17 < karlp> not the hosting provider, the software solution operator, and yes, they probably coudl have, but they said, "set up a cname to blah, and give us a cert"
2020-02-13T17:56:39 < karlp> and giving them a cert was a fuck less effort than, "but guys, are you not lets encrypting?!"

2020-02-13T18:10:32 < zyp> I mean, the way I see it, docker compose was designed to describe throwaway test setups, which I guess it does well
2020-02-13T18:10:32 < doomba> lol you wanna know why i use docker-compose? because i can just stick it in the repo and make my .gitlab-ci.yml run docker-compose rofl
2020-02-13T18:11:01 < karlp> I was trying out streamsheets recently, tried to use it's docker deployment so I could "just try it out" and it was like 10 separate containers as well.

2020-02-13T18:11:31 < doomba> yeah tbf this logbook-radio thing makes sense to split up into a bunch of containers
2020-02-13T18:11:58 < zyp> I considered trying UNMS, it's got a fucking script that does a bunch of changes to the host too, which kinda defeats the point of using containers

2020-02-13T18:53:35 < kakimir> thanks
2020-02-13T18:53:56 < zyp> for(A; B; C) {D;} is equivalent to for(A; B;) {D; C;}
2020-02-13T18:54:09 < zyp> so if you break in D, C won't get executed
2020-02-13T18:54:19 < PaulFertser> But if you continue...

2020-02-13T18:56:52 < emeb> haha - hooked one of those Lyontek 8MB SPI RAMs on an STM32F373 and used it as an audio delay buffer. Kinda slow, but it works.

2020-02-13T18:57:15 < kakimir> oh ram.. nvm

2020-02-13T18:58:10 < emeb> "proof of concept"
2020-02-13T18:58:28 < emeb> would be much better on newer STM32 with QSPI port running much faster.

2020-02-13T19:16:53 < jpa-> the filter stuff could be actually quite useful in many cases, but a bit annoying to set up
2020-02-13T19:17:33 < jpa-> same for cordic, though the speed benefit vs. table lookup is not very large, and i think it is a bit rare to have a lot of trigonometry that you could do on background with dma
2020-02-13T19:17:42 < emeb> they could have made the CORDIC stuff a bit more useful with minor changes
2020-02-13T19:18:00 < emeb> would have been nice to have a "rotate" mode.
2020-02-13T19:19:54 < jpa-> doesn't it already have a rotate mode?
2020-02-13T19:21:05 < jpa-> or maybe it doesn't, i guess the "rotation and vectoring modes" means something else
2020-02-13T19:25:40 < aandrew> cordic is one area I want to spend some time getting to know
2020-02-13T19:25:45 < aandrew> specifically in VHDL
2020-02-13T19:26:42 < emeb> it's worth your time
2020-02-13T19:26:51 < emeb> I used it pretty heavily in the past
2020-02-13T19:34:43 < englishman> emeb: the fmac is indeed "looks good on paper" but who doesn't want to implement a 51 tap fir with basically no overhead
2020-02-13T19:35:45 < emeb> englishman: yep - would be handy.
2020-02-13T19:37:34 < emeb> if the CORDIC block had a "rotate" mode then it could be used for quadrature mixing/tuning. Couple that (via DMA) with the filter block and you could do some basic SDR stuff.

2020-02-13T19:40:38 < emeb> not AFAICT
2020-02-13T19:41:01 < emeb> you can get sine/cosine of an angle + magnitude
2020-02-13T19:41:01 < jpa-> yeah, i can't find it rotating either, even though it mentions "rotation and vectoring modes"
2020-02-13T19:42:07 < emeb> I guess rotation would require 3 arguments - x, y, angle
2020-02-13T19:42:13 < zyp> I wanna read about this CORDIC, anyone got a RM number handy?
2020-02-13T19:42:20 < jpa-> RM0440
2020-02-13T19:42:27 < zyp> thanks
2020-02-13T19:43:02 < jpa-> emeb: yeah; i guess you could get rotation by constant angle by passing the data many times through FMAC block
2020-02-13T19:43:25 < emeb> true
2020-02-13T19:44:01 < jpa-> but if it requires multiple passes, one needs to divide data into blocks etc.

2020-02-13T19:45:54 < emeb> you could do 2 passes thru CORDIC to get rotation - get the phase/modulus in 1st pass, sum desired angle with phase and then do 2nd pass to get x, y of rotated point.
2020-02-13T19:46:44 < emeb> debatable if that's more efficient than just doing the math outright tho
2020-02-13T19:46:59 < jpa-> yeah, rotation by constant angle is quite simple after all, 4 multiplications
2020-02-13T19:48:46 < zyp> you could use the CORDIC to create the rotation matrix
2020-02-13T19:49:03 < zyp> if it's rotation by a varying angle
2020-02-13T19:49:36 < emeb> yup
2020-02-13T19:50:59 < zyp> I mean, if you've got a cartesian vector and an angle you wanna rotate it by, you can either do two passes of CORDIC with an addition in between or one pass of CORDIC and four muladds

2020-02-13T19:54:39 < emeb> Right. I've got no feeling for how quickly the CORDIC iterates one pass. It appears to be a serial process though, so it might be faster to just do the 4 multadds than wait for it.
2020-02-13T20:04:08 < jpa-> somewhere it was said 4 bits per clock, so one might assume 8 clocks per 32bit word
2020-02-13T20:09:38 < emeb> yes - 24 iterations (6 cycles) max.

2020-02-13T20:23:08 < qyx> no
2020-02-13T20:23:12 < qyx> unly the AF table
2020-02-13T20:23:37 < qyx> and it is a systematic "error"
2020-02-13T20:23:48 < qyx> there are such pins for can1, can2, can3 and for tx and rx
2020-02-13T20:24:39 < englishman> different pins for FD mode? lol

2020-02-13T20:24:51 < englishman> useless response
2020-02-13T20:27:50 < qyx> uhm, so it appears the FD functionality may be available on txfd/rxfd pins

2020-02-13T22:04:07 < qyx> the gpio layer is independent of alternate functions
2020-02-13T22:04:19 < qyx> the pin corresponding to MISO can still be configured as output

2020-02-14T00:47:41 < aandrew> heh
2020-02-14T00:49:23 < aandrew> started reading about moving median filters (instead of moving average filters) and now I'm reading about counting leading zeroes 
2020-02-14T00:50:01 < aandrew> seems that for moving median the best way unless you have huge arrays is just a quicksort and pick the middle of the array of values
2020-02-14T00:50:29 < aandrew> quickselect works on unsorted arrays but destroys the array anyway so it's still consuming twice the memory unless you can use the median after you're done with the samples
2020-02-14T00:51:18 < BrainDamage> if you do moving median, you can use sorted insertion
2020-02-14T00:51:28 < aandrew> yes
2020-02-14T00:51:32 < aandrew> that's an alternative
2020-02-14T00:51:52 < aandrew> but I'm thinking in terms of sampling some analog value and needing the data on it
2020-02-14T00:51:55 < aandrew> in it*
2020-02-14T00:52:10 < Laurenceb> I've used quicksort in the past
2020-02-14T00:52:21 < Laurenceb> to deal with motor noise and stuff like than 
2020-02-14T00:52:30 < aandrew> yep
2020-02-14T00:52:40 < Laurenceb> > a quicksort and pick the middle of the array of values
2020-02-14T00:52:45 < aandrew> the whole basis of moving median rather than moving average is to completely ignore outliers 
2020-02-14T00:53:34 < Laurenceb> ranok at about 1Msps on f4
2020-02-14T00:54:02 < Laurenceb> but window length was only 20 samples or so iirc
2020-02-14T00:54:11 < aandrew> yeah that's what I'm thinking too
2020-02-14T00:54:43 < aandrew> most times if you're sampling something you're not going to be averaging much more than 8-64 samples so either an insertion sort or quicksort will be almost free 
2020-02-14T00:55:09 < aandrew> and if you really do want to have the median of a long list, you probably only need that *after* you've done something with the list anyway
2020-02-14T00:55:20 < aandrew> so a destructive quickselect doesn't matter
2020-02-14T00:55:51 < BrainDamage> the nice thing about keeping the sorted vector is that you can do frequency binning almost for free
2020-02-14T00:56:26 < BrainDamage> frequency in the statistical sense, not the fourier transform
2020-02-14T00:57:09 < aandrew> *nods* curious what you were using statistical frequency of the sample values for?
2020-02-14T00:57:37 < BrainDamage> tracking filter
2020-02-14T00:57:47 < bitmask> I usually use median filters over average
2020-02-14T00:57:59 < bitmask> well I guess it depends on the case
2020-02-14T00:58:04 < aandrew> https://community.arm.com/developer/ip-products/processors/b/processors-ip-blog/posts/a-fairly-quick-count-leading-zeroes-for-cortex-m0, the comment on Julius Goryavsky's algorithm looks interesting
2020-02-14T00:58:32 < aandrew> I tend to use moving average but the specific issues of dealing with outliers is why I've becme interested in this
2020-02-14T00:59:54 < Cracki> how is counting leading zeroes related to median?

2020-02-14T07:07:48 < doomba> does it matter what dma and channel?
2020-02-14T07:08:07 < jpa-> some trigger sources are only available on some channels
2020-02-14T07:08:30 < jpa-> you'll find a list of that somewhere in refman, but where exactly varies by device
2020-02-14T07:08:39 < doomba> http://libopencm3.org/docs/latest/stm32g0/html/group__usart__file.html#ga223b4141d19ac1f6a7dd2045c504e994
2020-02-14T07:08:57 < doomba> i haven't been able to find anything table or anything regarding this
2020-02-14T07:08:58 < jpa-> also, some dma controllers cannot access all peripherals, that is shown in bus matrix in "memory" section of refman
2020-02-14T07:09:12 < doomba> it seems on the g0 i can use dma1 channel1 for any usart 1 or usart 2
2020-02-14T07:09:14 < jpa-> doomba: did you look in the reference manual of the part you are using?
2020-02-14T07:09:19 < doomba> jpa-: yes
2020-02-14T07:09:23 < doomba> and it has this dmamux shit
2020-02-14T07:09:42 < doomba> but the dmamux appears to only be needed for _not_ dma1 channel1
2020-02-14T07:10:03 < doomba> i generated code with stm32cubemx to confirm if this was the case
2020-02-14T07:10:14 < doomba> it uses dma1 channel1 and doesn't touch anything to do with dmamux
2020-02-14T07:10:45 < doomba> i think maybe the documentation is giving a list of dma and channel to use from F1 part not g0
2020-02-14T07:12:14 < jpa-> the section you want to look at is "9.3.2 DMA request mapping"
2020-02-14T07:14:38 < jpa-> and yeah, don't trust libopencm3 documentation to be up to date or updated for the particular family
2020-02-14T07:15:05 < jpa-> also, don't trust cubemx to always generate everything you need
2020-02-14T07:17:37 < doomba> was using cubemx to see if i was doing anything obviously wrong like missing some clock setup step
2020-02-14T07:19:40 < jpa-> yeah, it's a good try
2020-02-14T07:19:48 < jpa-> but not always finds the trouble :)
2020-02-14T07:20:48 < doomba> yeah this part is a biiiiiiiiiiiitch
2020-02-14T07:20:50 < doomba> because i can't debug it
2020-02-14T07:21:10 < jpa-> why can't you?
2020-02-14T07:21:16 < doomba> becaues it's the 8 pin
2020-02-14T07:22:40 < doomba> http://dpaste.com/3SXQQ2T
2020-02-14T07:22:49 < jpa-> it has SWD available, right? are you using the io for something else
2020-02-14T07:23:20 < doomba> see code. i'm using usart
2020-02-14T07:23:26 < doomba> which eats one of the swd pins
2020-02-14T07:23:36 < jpa-> nice :)
2020-02-14T07:23:54 < doomba> unless maybe there is a way to remap the swd pins after the fact
2020-02-14T07:24:45 < doomba> i've confirmed that usart stuff is working here. i can transmit from the part and rx in blocking mode
2020-02-14T07:24:49 < jpa-> why not using the usart on PA9/PA10?
2020-02-14T07:26:05 < doomba> that would be pins 5 and 6
2020-02-14T07:26:10 < doomba> it's still eating a swd there
2020-02-14T07:26:16 < doomba> plus the pcb is not traced out for that
2020-02-14T07:26:29 < jpa-> traces are there to be cut and patched :)
2020-02-14T07:26:35 < jpa-> isn't swd 7&8?
2020-02-14T07:26:47 < doomba> ah yes you're right 7 & 8

2020-02-14T07:30:37 < doomba> code wise
2020-02-14T07:35:26 < doomba> you did just give me a hilarious idea
2020-02-14T07:37:04 < doomba> the pcb is wired for pin 8 and 1
2020-02-14T07:37:32 < doomba> but i can use 5 & 6 for uart while testing because i just soic8 clip it
2020-02-14T07:37:58 < doomba> if i can get the usart dma stuff working that way, then i'll just move it over

2020-02-14T14:55:50 < englishman> unfortunately
2020-02-14T14:58:33 < BrainDamage> put a buck-boost in front and with a giant filter

2020-02-14T21:54:33 < doomba> Thorn: hey you did dma usart on stm32g0 ?
2020-02-14T22:03:11 < Thorn> doomba: haven't touched g0 yet but is it really that different from f0 or l0?
2020-02-14T22:03:11 < zyp> is g0 any different from other families in that regard?
2020-02-14T22:04:07 < doomba> that i'm not sure. i'm trying to figure out what setup i'm missing for DMA to work
2020-02-14T22:04:44 < doomba> http://dpaste.com/246X71G
2020-02-14T22:04:59 < doomba> lemme know if you see anything i'm not doing?
2020-02-14T22:05:11 < doomba> i know usart is setup correctly because i can send and receive using the blocking functions
2020-02-14T22:05:24 < zyp> RCC_DMA and RCC_DMA1? weird naming
2020-02-14T22:05:24 < doomba> also the idle interrupt is working
2020-02-14T22:05:44 < doomba> i initially had RCC_DMA1 only then i saw there is a RCC_DMA and thought that's maybe the dmamux
2020-02-14T22:05:53 < doomba> so enabled that too. didn't seem to wake up dma
2020-02-14T22:06:26 < doomba> in this code, the dma1_channel4_7_dmamux_isr is not firing on HT nor TC interrupts
2020-02-14T22:07:14 < doomba> i've also tried dma1_channel1, which doesn't appear to use the dmamux? but i set the dmamux channel request to dma1 channel1 anyway (for usart1_rx)
2020-02-14T22:08:15 < doomba> i have the RM, some bullshit blog post written for g0 but probably never tested on g0, and stm32cubemx generated code for dma usart
2020-02-14T22:08:52 < doomba> some of the stuff in my code is taken from those sources - like disabling the fifo, which is a recurring theme with g0
2020-02-14T22:09:21 < Thorn> ok so dma does seem different
2020-02-14T22:09:42 < zyp> nothing sticks out as obviously wrong when I just skimmed through it
2020-02-14T22:09:49 < doomba> the dma setup stuff seems the same as far as libopencm3 is concerned - and i took code that i know works on f1
2020-02-14T22:09:55 < zyp> but then I've never used libopencm3 myself
2020-02-14T22:10:02 < zyp> or g0
2020-02-14T22:10:41 < doomba> this is the stm32g031 in the soic8 but jpa- said to put the usart on different pins so i can still have swd

2020-02-14T22:11:00 < zyp> this is the sort of problem I'd work on by peeking and poking registers directly in the debugger
2020-02-14T22:11:31 < zyp> does the uart itself work without dma?
2020-02-14T22:11:34 < doomba> yep
2020-02-14T22:11:53 < doomba> i haz gdb attached too
2020-02-14T22:11:58 < doomba> that's how i know the dma interrupts are not firing
2020-02-14T22:12:26 < zyp> did you peek the dma registers? you can look at the count to see progress of a job
2020-02-14T22:13:50 < doomba> not directly, but i think the same is being seen in my rx() function
2020-02-14T22:13:56 < Thorn> Cygnus launch postponed for another 24 hrs
2020-02-14T22:14:00 < doomba> dma_get_number_of_data() always returns 0
2020-02-14T22:14:24 < doomba> the rx() gets called from the usart1_isr() ofc - not the dma handler as it's never fired
2020-02-14T22:14:35 < zyp> sounds like dma requests aren't getting through then
2020-02-14T22:14:45 < specing> Thorn: whyu
2020-02-14T22:14:48 < zyp> double check the channels
2020-02-14T22:15:14 < doomba> i don't know where in the ref manual it says "usart must be on such and such dma request and channel" if there is such a thing?
2020-02-14T22:15:26 < zyp> DMA chapter
2020-02-14T22:15:41 < zyp> are there one or two DMA engines?
2020-02-14T22:15:55 < zyp> in other families with two, one of the engines can't access all peripherals
2020-02-14T22:16:28 < Thorn> specing: upper level winds
2020-02-14T22:17:04 < specing> their rocket can't pass those?
2020-02-14T22:17:10 < specing> such strong MIC
2020-02-14T22:17:53 < Thorn> they're very good at collecting overtime pay though
2020-02-14T22:18:05 < Thorn> if you launch the first time you only get paid once
2020-02-14T22:18:21 < specing> hah, damn true
2020-02-14T22:22:04 < zyp> you guys get paid?
2020-02-14T22:22:48 < zyp> nobody paid me when I were payload manager for a launch
2020-02-14T22:27:19 < doomba> Thorn: hahahahahahahahaahahahahaahahahaha
2020-02-14T22:27:23 < doomba> guess what it was
2020-02-14T22:27:42 < doomba> i was setting up the dmamux channel request routing stuff
2020-02-14T22:27:56 < doomba> and passing DMA1 instead of DMAMUX1 as the register address
2020-02-14T22:28:16 < Steffanx> probably because it was school and you got paid with experience, zyp?
2020-02-14T22:28:28 < doomba> dmamux_set_dma_channel_request(DMA1, DMA_CHANNEL5, blablhablbalh) was the issue. it's supposed to be DMAMUX1 not DMA1
2020-02-14T22:32:48 < zyp> Steffanx, yep

2020-02-14T22:43:01 < karlp> zyp: in a few placs thehre's _DMA as an alias for _DMA1 for those families that only have one, so that the names match the docs, likewise for DAC/DAC1
2020-02-14T22:43:31 < zyp> yeah, that's what I assumed
2020-02-14T22:43:40 < zyp> calling both is weird :)
2020-02-14T22:43:47 < zyp> s/calling/enabling/
2020-02-14T22:44:50 < karlp> that dmamux looks confusing though, never used that before.
2020-02-14T22:45:31 < zyp> haven't looked at it, but having dma request routing as a separate thing independent of the dma channels itself sounds like it might be useful
2020-02-14T22:45:40 < zyp> at least if it can route any request to any channel

2020-02-14T23:06:17 < mawk> kakimir 
2020-02-14T23:06:17 < doomba> stupid pointless stm32g0 board that sniffs serial printks for "enter passphrase" and "types it" in
2020-02-14T23:06:51 < kakimir> mawk, delimiter
2020-02-14T23:07:35 < kakimir> btw decimal thingie works fine
2020-02-14T23:07:46 < kakimir> only hex thingie doesn't
2020-02-14T23:07:57 < kakimir> value 0 is set to variable
2020-02-14T23:09:03 < mawk> it's not a delimiter
2020-02-14T23:09:05 < mawk> it's the end pointer
2020-02-14T23:09:14 < mawk> used for error detection
2020-02-14T23:09:35 < mawk> In particular, if *nptr is not '\0' but **endptr is '\0'
2020-02-14T23:09:36 < mawk>        on return, the entire string is valid.
2020-02-14T23:10:13 < mawk> so meh
2020-02-14T23:10:16 < mawk> just put NULL there
2020-02-14T23:11:01 < mawk> also you can combine the two with a base of 0 kakimir 
2020-02-14T23:11:05 < mawk> it parses the 0x at start
2020-02-14T23:11:06 < mawk> pro tip
2020-02-14T23:11:44 < kakimir> tell me again
2020-02-14T23:11:59 < mawk> so
2020-02-14T23:12:07 < mawk> let me show you code
2020-02-14T23:12:10 < mawk> hold on
2020-02-14T23:12:15 < kakimir> if I use 0 it's automagic?
2020-02-14T23:12:20 < mawk> yes
2020-02-14T23:12:20 < kakimir> no strcmp?
2020-02-14T23:12:24 < mawk> indeed
2020-02-14T23:12:25 < kakimir> sweet
2020-02-14T23:12:28 < mawk> also, do error detection
2020-02-14T23:12:35 < mawk> then you don't have to manually check if it's a number
2020-02-14T23:12:35 < kakimir> why
2020-02-14T23:12:39 < mawk> why ???
2020-02-14T23:12:45 < mawk> because you want to know if it's a number
2020-02-14T23:12:45 < kakimir> it wont crash it
2020-02-14T23:12:52 < kakimir> I check it
2020-02-14T23:13:02 < kakimir> first char
2020-02-14T23:13:08 < mawk> you check only the first
2020-02-14T23:13:12 < kakimir> sure
2020-02-14T23:13:41 < mawk> if you do error checking you don't have to check the first
2020-02-14T23:13:45 < mawk> you check them all, for free
2020-02-14T23:14:03 < kakimir> program prints those variables also there is multiple restrictions for those variables
2020-02-14T23:14:16 < kakimir> it workens well
2020-02-14T23:15:13 < kakimir> if things go shit it returns 0 or so
2020-02-14T23:15:18 < kakimir> or some crazy number
2020-02-14T23:16:51 < mawk> ?
2020-02-14T23:17:00 < mawk> no
2020-02-14T23:17:06 < mawk> it returns all the numbers in the front
2020-02-14T23:17:08 < mawk> and ignores garbage
2020-02-14T23:17:15 < mawk> anyway it's even less code lol
2020-02-14T23:17:17 < mawk> just use it
2020-02-14T23:17:35 < kakimir> not interested in that detail atm.
2020-02-14T23:17:42 < kakimir> or ever
2020-02-14T23:18:03 < kakimir> maybe in critical application
2020-02-14T23:18:20 < kakimir> this program doesn't have effects put stdout and stderr
2020-02-14T23:18:24 < kakimir> *but
2020-02-14T23:21:19 < kakimir> okay show me
2020-02-14T23:22:20 < mawk> what are you talking about lol
2020-02-14T23:22:29 < mawk> it's not because you don't write mission critical code that you don't check errors
2020-02-14T23:22:38 < mawk> it's just better in every aspect possible, including for you when you code
2020-02-14T23:22:59 < jadew> I realized something
2020-02-14T23:23:17 < jadew> with china on hold, the postal service probably works like never before
2020-02-14T23:23:45 < mawk> kakimir: https://ideone.com/FE0uIy
2020-02-14T23:24:26 < kakimir> sweet
2020-02-14T23:24:28 < kakimir> thanks!
2020-02-14T23:25:13 < kakimir> jadew: I doubt
2020-02-14T23:25:18 < kakimir> problems are local
2020-02-14T23:25:22 < kakimir> not global
2020-02-14T23:25:25 < mawk> you can put that parse_number function in a header file
2020-02-14T23:25:35 < mawk> at least with less china you have less packages
2020-02-14T23:25:41 < mawk> everyone orders from china
2020-02-14T23:25:46 < kakimir> > has a header file
2020-02-14T23:25:52 < kakimir> :D
2020-02-14T23:26:01 < mawk> lol
2020-02-14T23:26:03 < kakimir> this is .c
2020-02-14T23:26:13 < mawk> yeah C has header
2020-02-14T23:26:19 < mawk> so, you see how the erorr testing is done
2020-02-14T23:26:19 < kakimir> thousand line singlefile
2020-02-14T23:26:27 < kakimir> it makes sense
2020-02-14T23:26:37 < kakimir> examples I saw didn't have that
2020-02-14T23:26:44 < mawk> they're doing it wrongly
2020-02-14T23:26:44 < kakimir> simples
2020-02-14T23:26:50 < mawk> the only way to check error with strtoul is like that
2020-02-14T23:26:57 < mawk> because the "error value" which is -1 can be a valid number
2020-02-14T23:27:02 < mawk> you have no way of telling
2020-02-14T23:27:11 < mawk> also strtoul parses "123garbage" as 123 and you don't know
2020-02-14T23:27:53 < kakimir> good
2020-02-14T23:28:19 < kakimir> I want to parse magnitudes from [len-1]
2020-02-14T23:28:29 < kakimir> ie. 'k'
2020-02-14T23:28:47 < mawk> ah
2020-02-14T23:28:48 < mawk> then
2020-02-14T23:28:53 < mawk> you can use the garbage processing
2020-02-14T23:28:56 < mawk> let me show you
2020-02-14T23:29:07 < kakimir> find that k from there?

2020-02-15T00:07:39 < karlp> have a failed ac/dc "supply" for some christmas lights, puleld it open, fully potted, only visible component is a KBL610 bridge rectifier.  how is this meant to work? the lights are all equally bright, whether I have one section or two or three plugged in, but if I unscrew a bulb they're out.
2020-02-15T00:08:05 < karlp> also, I presume there's a "standard" pinout, because the datasheet doesn't mention it :)

2020-02-15T00:16:43 < jadew> it hasn't moved
2020-02-15T00:16:49 < jadew> they just scanned it and it sits there
2020-02-15T00:17:13 < jadew> still in the warehouse
2020-02-15T00:17:46 < jadew> this is before they decide on weather it goes to customs or straight to my mail box
2020-02-15T00:19:24 < Steffanx> China package in quarantine?
2020-02-15T00:19:41 < jadew> crossed my mind
2020-02-15T00:21:58 < jadew> do you guys have a photo port on your microscopes?
2020-02-15T00:22:15 < jadew> if you put an eyepiece in there, does it just work?
2020-02-15T00:22:43 < jadew> mine has a photo port, but doesn't have the tube and I was thinking of printing one and also buying an extra eyepiece to put there
2020-02-15T00:22:54 < jadew> then I can use a webcam on top of it

2020-02-15T01:52:51 < qyx> mhm, kicad connected a "IN" global label to a pad named "IN"
2020-02-15T01:52:58 < qyx> and now I cannot force it to disconnect
2020-02-15T01:59:57 < qyx> fuck kicad
2020-02-15T02:00:04 < qyx> if I mark a symbol pad as a power input
2020-02-15T02:00:36 < qyx> the same pad of ALL such symbols in the WHOLE schematic is conencted together
2020-02-15T02:00:49 < qyx> regardless of labels, etc.
2020-02-15T02:01:37 < qyx> eg. i have 3x TPS2595 power switches in the sch, two going from the 5
2020-02-15T02:01:47 < qyx> +5V bus, one from the +12V bus
2020-02-15T02:02:16 < qyx> kicad connects them together selecting one of the names or a name of a label if there is any
2020-02-15T02:02:40 < qyx> and all +5Vs and +12Vs in the whole sch becomes shit

2020-02-15T02:04:59 < Cracki> "then maybe you shouldn't be doing that" is the standard response of ppl who think they know better and need to force it on you
2020-02-15T02:06:06 < qyx> maybe I am doing something wrong
2020-02-15T02:06:13 < qyx> but cannot find what
2020-02-15T02:06:38 < qyx> changing it from "power input" to "input" automagically solves it
2020-02-15T02:08:10 < Cracki> maybe it has special logic for power pads (vs non-power pads)
2020-02-15T02:08:38 < Cracki> sounds like it treats labels of power pads as global regardless

2020-02-15T03:02:38 < kakimir> On success, the function returns the same str parameter. If the End-of-File is encountered and no characters have been read, the contents of str remain unchanged and a null pointer is returned.
2020-02-15T03:02:58 < jadew> what?
2020-02-15T03:03:32 < jadew> you're adding something to str?

2020-02-15T03:04:34 < Cracki> how the fuck does an emulator not work on amd

2020-02-15T03:05:04 < Cracki> does it say amd to blame?

2020-02-15T03:05:29 < Cracki> kakimir, on windows maybe? things on windows still think they need to transparently convert line endings between \n and \r\n

2020-02-15T03:07:37 < Cracki> I doubt "hyper-v runs" is sufficient indication
2020-02-15T03:07:58 < Cracki> so they have a new version that requires newer cpu features?
2020-02-15T03:08:11 < jadew> I think so
2020-02-15T03:08:27 < kakimir> if I seek to start of file with 0 offset

2020-02-15T03:10:42 < Cracki> when I looked at components recently, an RTX 2080 gpu costs an arm and a leg, and I didn't dare look at 2080 TI or above

2020-02-15T03:11:04 < jadew> it's because of the stupid bitcoins
2020-02-15T03:11:25 < jadew> that's what drove video card prices up
2020-02-15T03:11:29 < Cracki> mining buttcoin is the "value creator" mindset
2020-02-15T03:11:35 < Cracki> just speculate with them, gets you more
2020-02-15T03:11:51 < Cracki> an RTX 2070 is barely slower but a lot cheaper than 2080
2020-02-15T03:12:21 < Cracki> still I see gamers who seem to have too much disposable "income"

2020-02-15T03:36:45 < bitmask> never tried anything docker
2020-02-15T03:36:49 < Cracki> use spreadsheets
2020-02-15T03:37:13 < Cracki> I think I touched docker once, decided it's more trouble than it's worth for me, and left it at that
2020-02-15T03:39:27 < fenugrec> it's kind of my feeling too. For someone wanting to run 4-5 dockers it'd be worth learning, but jeez... can't be pro at everything
2020-02-15T03:39:33 < Cracki> when you want to run queries on your data, and excel can't run your query anymore, you'll know that you've outgrown spreadsheets
2020-02-15T03:39:59 < Cracki> but that just means you need a database and some simple CRUD interface
2020-02-15T03:40:03 < sync> fenugrec: running docker is easy
2020-02-15T03:40:20 < sync> but partkeepr is a pos, although probably good enough
2020-02-15T03:40:28 < fenugrec> yea yea I can copy-paste a handful of docker commands, that doesn't mean I understand shit and can manage it in the long term
2020-02-15T03:40:32 < Cracki> ^
2020-02-15T03:40:58 < Cracki> that was my feeling with git in the beginning too... it got better when I discovered the programs you actually use on top of it that make life bearable
2020-02-15T03:40:58 < sync> that's about it tho
2020-02-15T03:41:13 < sync> you mean, the shell Cracki?
2020-02-15T03:41:18 < Cracki> evangelists never tell you how to have an easy life
2020-02-15T03:41:24 < Cracki> they always mock you
2020-02-15T03:42:06 < Cracki> when you ask them to explain shit in plain terms, they say "homeomorphic endofunctors mapping submanifolds of a Hilbert space”

2020-02-15T03:44:12 < Cracki> yeah good summary
2020-02-15T03:44:43 < fenugrec> I use git enough from the CLI to understand it reasonably well, but it was a learning curve all right
2020-02-15T03:46:36 < fenugrec> "gitk" makes things so much easier to understand

2020-02-15T03:47:21 < Cracki> I can disrecommend gitkraken. they fail at everything.

2020-02-15T03:50:08 < fenugrec> I believe the worst git messes are spawned by ill-advised, GUI-based operations
2020-02-15T03:51:18 < Cracki> a gui can deceive you, a command line isn't discoverable at all
2020-02-15T03:51:54 < Cracki> I'd rather have a gui fuck things up and then make a bug report for that, than be left with merely command line interface to a VERY COMPLEX tool
2020-02-15T03:52:37 < Cracki> hm ok well, complexity of tool isn't it, complexity of interface
2020-02-15T03:52:45 < Cracki> say you want to rebase something
2020-02-15T03:53:24 < Cracki> simple concept, but don't expect me to remember the fucking order of arguments for a command line
2020-02-15T03:54:17 < Cracki> ppl scoff at interactivity because it's not elite enough

2020-02-15T05:07:00 < kakigate> I made a repo there
2020-02-15T05:12:54 < Cracki> great, git clone it
2020-02-15T05:13:10 < Cracki> on the right there's a button and a link or command line you can copy and run
2020-02-15T05:14:04 < Cracki> when you clone that repo, your local copy automatically has github set up as a "remote" and as the default remote for pushing

2020-02-15T05:25:07 < kakigate> how to add photos to readme.md
2020-02-15T05:25:25 < kakigate> do I include them in project
2020-02-15T05:27:37 < Cracki> yes you put them in the repo itself, then edit readme.md and add a photo tag (markdown)
2020-02-15T05:28:01 < kakigate> are those photos included in clone?
2020-02-15T05:28:21 < Cracki> if you put the photos in the github repo and _then_ clone, they'll be in the clone too
2020-02-15T05:28:32 < Cracki> if you clone first, then add pics, you will need to synchronize ("pull")
2020-02-15T05:28:46 < Cracki> or push as it were, if you add them locally and want them on github
2020-02-15T05:44:47 < kakigate> so
2020-02-15T05:45:12 < kakigate> I made master branch in github and I should not have or something
2020-02-15T05:45:24 < kakigate> now it doesn't want to merge in any direction
2020-02-15T05:45:45 < Cracki> uh... start over :>
2020-02-15T05:45:52 < Cracki> you can delete branches, no problem
2020-02-15T05:46:03 < kakigate> delete readme.md?
2020-02-15T05:46:10 < kakigate> only thing in there
2020-02-15T05:46:26 < kakigate> doesn't work that way does it?
2020-02-15T05:46:34 < Cracki> what do you want to do?
2020-02-15T05:46:42 < Cracki> simply have a repo with some pics and a readme?
2020-02-15T05:47:09 < kakigate> and source
2020-02-15T05:47:28 < kakigate> in initialization I created something when I should not have
2020-02-15T05:48:24 < Cracki> let me guess, you have a local repo already, and it's got commits in it?
2020-02-15T05:48:36 < jadew> SARS-CoV-2 - the new name of the virus
2020-02-15T05:48:44 < Cracki> can they stop inventing names for it
2020-02-15T05:48:50 < Cracki> covid is retarded already
2020-02-15T05:48:59 < jadew> that's the name of the disease
2020-02-15T05:49:05 < jadew> COVID-19
2020-02-15T05:49:11 < kakigate> cracki: yes I followed the guide
2020-02-15T05:49:15 < Cracki> wat guide
2020-02-15T05:49:24 < kakigate> github for noobs
2020-02-15T05:49:29 < kakigate> so I need to remove local commit
2020-02-15T05:49:52 < Cracki> how about you delete the repo on github and create a new one on github
2020-02-15T05:50:03 < Cracki> without anything, no readme, no commits
2020-02-15T05:50:20 < Cracki> then tell your local repo that *that* is a new remote, call it "origin"
2020-02-15T05:50:29 < Cracki> then you can push to that repo on github
2020-02-15T05:50:37 < Cracki> and since it has no commits yet, pushing will succeed
2020-02-15T05:51:14 < Cracki> likely what happened is that you have commits in two different repos, but these commits have no common ancestor (commit), so of course merging will fail

2020-02-15T12:48:49 < Steffanx> you should dedicate your music to kakigate, antto
2020-02-15T12:49:35 < antto> why?
2020-02-15T12:49:56 < antto> did he die or sumfin?

2020-02-15T12:51:25 < antto> STAY WITH US!
2020-02-15T12:51:28 < Steffanx> lol, no. I meant thant you should say: Here kakigate, have sum musics: [url]. 
2020-02-15T12:52:21 < antto> my impression is that he listens to old crap music (according to my taste)
2020-02-15T12:52:34 < antto> so he wouldn't like the above
2020-02-15T12:53:08 < Steffanx> true that. but you have to keep trying to change that
2020-02-15T12:53:41 < antto> i know how to fix his music taste, but it would require physical measures
2020-02-15T12:54:02 < Steffanx> i dont think he would mind electro shock therapy.
2020-02-15T12:54:32 < antto> more like, being tied and getting his ears bleached with the right kind of music for a long enough time

2020-02-15T16:09:51 < dongs> can i nak a send?
2020-02-15T16:09:53 < Cracki> iirc slave sends nack
2020-02-15T16:10:14 < Cracki> as for "fit into buffer", clock stretching if it's just too fast

2020-02-15T16:13:37 < Cracki> they don't mention clock stretching, must be a very brief introduction
2020-02-15T16:14:08 < dongs> yeah i dont care about stretching
2020-02-15T16:14:19 < dongs> i wonder if I should even care about signalling error since this is a protocol thats internal to my use
2020-02-15T16:14:27 < dongs> im already ignoring shit over buffer size
2020-02-15T16:14:36 < dongs> master can send whatever but since i control both it doesnt really matter
2020-02-15T16:15:57 < Cracki> nack/aborting could save time, if that's a concern
2020-02-15T16:16:18 < dongs> i'd have to check if my master (some 8051 trash) will actually handle a nack half-way through a send heh

2020-02-15T17:08:55 < dongs> 2L only, slow, no 4L
2020-02-15T17:09:02 < doomba> osh park is like $50 a pcb
2020-02-15T17:09:05 < dongs> lmao
2020-02-15T17:09:12 < dongs> we've been getting an increase of pcb orders as well
2020-02-15T17:09:25 < doomba> you work for a murica pcb shop?
2020-02-15T17:09:34 < dongs> japan but yeah
2020-02-15T17:09:56 < doomba> and with increased demand means increased prices i imagine
2020-02-15T17:10:02 < qyx> aisler shipped on wednesday
2020-02-15T17:10:09 < qyx> I hope it comes on monday
2020-02-15T17:10:18 < qyx> they must have millions of orders
2020-02-15T17:10:23 < qyx> seeed is still not producing
2020-02-15T17:10:32 < qyx> my order is half done since Jan 16th
2020-02-15T17:10:44 < doomba> even though digikey is expensive, i'm glad i always buy components from there at least
2020-02-15T17:10:45 < qyx> no more progress
2020-02-15T17:10:53 < Thorn> I wonder if ST can move packaging out of Asia if it comes to that
2020-02-15T17:10:56 < doomba> digikey ships to me in like 2 days
2020-02-15T17:11:28 < doomba> though not sure if osh park gets their shit made in china or not
2020-02-15T17:11:31 < Thorn> doomba: what happens when digikey stocks are depleted
2020-02-15T17:11:40 < dongs> oshfuck is in murica
2020-02-15T17:11:41 < doomba> Thorn: prices go up, shortages ensue
2020-02-15T17:11:49 < dongs> thats why they cahrge $50 for board
2020-02-15T17:12:06 < doomba> i bet places like aidsfruit are already bulk buying shit to cover their own stuff anyway
2020-02-15T17:12:14 < doomba> so there's probabyl already price increases and shortages at digikey
2020-02-15T17:12:31 < qyx> fuk even TME announced shortages
2020-02-15T17:12:35 < qyx> yesterday
2020-02-15T17:12:37 < doomba> yea
2020-02-15T17:12:54 < doomba> companies are probably stockpiling in anticipation for shit ot get really bad
2020-02-15T17:13:24 < doomba> china was supposed to come off lockdown on feb 10 and they extended it, as i expected would happen.
2020-02-15T17:13:58 < doomba> it's too bad apple and wal*mart (communist star) still have carte blanche
2020-02-15T17:14:17 < doomba> imo china should stop THOSE production & shipping lanes too
2020-02-15T17:14:28 < doomba> to make the western consumer realize wtf is happening
2020-02-15T17:14:42 < qyx> my jlcpcb is  2020-02-14 10:10 HONG KONG HK / Departed on outbound flight
2020-02-15T17:14:52 < qyx> so awaiting nCoV
2020-02-15T17:14:54 < englishman> antto i could have sworn this was a hoahmaru remix
2020-02-15T17:15:14 < doomba> my last order from pine64 got stuck in chicago for a week for unknown reasons
2020-02-15T17:15:20 < dongs> i ordered shit from banggood and they shipped a couple hours later, so at least some shit in china is operating normally
2020-02-15T17:15:33 < doomba> yea
2020-02-15T17:15:34 < specing> isnt banggood in HK?
2020-02-15T17:15:37 < dongs> no
2020-02-15T17:15:38 < doomba> same with aliexp
2020-02-15T17:15:39 < Steffanx> shipped or set the status to shipped. there is a different :P
2020-02-15T17:15:41 < dongs> its guandong
2020-02-15T17:15:49 < dongs> steffanx, japan shipping is by OCS
2020-02-15T17:15:54 < dongs> shipped.
2020-02-15T17:15:57 < dongs> its very fast
2020-02-15T17:16:00 < specing> my state post said that all shipments are stopped
2020-02-15T17:16:03 < dongs> not some HK mail crap that doesnt track for  a month
2020-02-15T17:16:03 < doomba> afaik coronavirus can't survive the shipment
2020-02-15T17:16:14 < Steffanx> yet
2020-02-15T17:16:14 < doomba> unless they spit in a plastic bag and you eat it
2020-02-15T17:16:48 < doomba> that thinkpad fan from wutang province is fine
2020-02-15T17:16:50 < Thorn> https://www.sciencealert.com/study-shows-just-how-long-coronaviruses-can-stick-around-on-a-surface says up to 9 days
2020-02-15T17:16:57 < doomba> i huffed the air coming out of it as soon as i opened the package
2020-02-15T17:16:58 < Thorn> so express mail is DANGER
2020-02-15T17:17:02 < doomba> and so far i'm ok
2020-02-15T17:17:22 < doomba> haha yeah
2020-02-15T17:17:27 < doomba> so we're good then
2020-02-15T17:17:34 < doomba> just get the cheapest shipping option and wait 2 months like normal
2020-02-15T17:18:08 < Steffanx> aliexpress standard shipping can be under 9 days for me. doesnt work atm anyway, so .. im safe too.
2020-02-15T17:18:16 < doomba> tbf i thought jlcpcb and lcsc would be unaffected because they supposedly have remote sweatshop prison complexes that are fully self-sustaining in the mountains somewhere
2020-02-15T17:18:33 < dongs> lcsc is operating normally now according to their shit
2020-02-15T17:18:40 < dongs> im gonna try ordering somethign from there next week to see how it works
2020-02-15T17:18:42 < dongs> gonna be my first order
2020-02-15T17:19:16 < doomba> yea i guess i should draw up some pcbs this weekend
2020-02-15T17:19:18 < doomba> and see what happens
2020-02-15T17:19:28 < doomba> really don't want to order from osh
2020-02-15T17:19:33 < doomba> plus i want stencils
2020-02-15T17:19:41 < qyx> maybe I will reorder those seeeeds from jlcpcb instead
2020-02-15T17:20:03 < doomba> jlcpcb has always been about 2-3 weeks for me with the cheapest shipping option (epacket or w/e)
2020-02-15T17:20:06 < doomba> which is acceptable
2020-02-15T17:20:11 < doomba> i'm not in a hurry
2020-02-15T17:20:48 < qyx> I was not in a hurry on the beginning of Jan
2020-02-15T17:24:03 < Thorn> iirc like at least one of lcsc warehouses (the main one) is in the middle of Shenzhen
2020-02-15T17:25:18 < Thorn> btw how far is Shenzhen from Wuhan?

2020-02-15T18:15:34 < doomba> jpa-: thanks for help the other night
2020-02-15T18:15:39 < doomba> i finally got that dma crap working on stm32g0
2020-02-15T18:15:49 < jpa-> doomba: what was the last bug?
2020-02-15T18:15:54 < doomba> the lats bug was hilarious
2020-02-15T18:16:28 < doomba> i was trying to set up the dmamux routing and passing DMA1 instead of DMAMUX1 to the function
2020-02-15T18:17:01 < doomba> but switching the usart over to pins 5 & 6 was the ticket
2020-02-15T18:17:08 < doomba> it gave me enough incentive to get openocd working for g0
2020-02-15T18:17:25 < doomba> and from there it went so much smoother. no more guessing.
2020-02-15T18:17:51 < jpa-> :)
2020-02-15T18:17:53 < doomba> no more using win10 vm to connect under reset and do full chip erase 
2020-02-15T18:18:05 < jpa-> way too many people try to printf() debug their way out
2020-02-15T18:18:21 < doomba> and had i put more thought into which pins to use initially... but it worked out because i can soic clip these things
2020-02-15T18:18:40 < doomba> even though the pcb is wired for different pins - so when i finally got it working on 5 & 6 i just switched gpios and done
2020-02-15T18:20:17 < doomba> still have no idea why the st-links on these nucleo boards don't want to talk to the g0
2020-02-15T18:20:25 < doomba> but the $5 stlink from amazon do
2020-02-15T18:20:46 < doomba> doesn't matter at this point
2020-02-15T18:21:12 < jpa-> did you remove the jumpers that link onto on-board mcu?

2020-02-15T18:36:12 < jpa-> doomba: i mean on the nucleo, there are a pair of jumpers you need to remove if you want to use the stlink to connect to external mcu
2020-02-15T18:36:34 < jpa-> (and if it has a Vdd jumper, you usually don't want to remove that because it would hold NRST down)
2020-02-15T18:36:43 < doomba> yep
2020-02-15T18:36:45 < doomba> did all that
2020-02-15T18:36:48 < jpa-> ok
2020-02-15T18:36:52 < doomba> and confirmed it works with another mcu

2020-02-16T01:56:21 < invzim> buck
2020-02-16T01:56:35 < zyp> usb-c has a debug mode, but to use it properly you'd have to have a bit of sense logic to detect whether a debugger or a normal cable is connected
2020-02-16T01:56:55 < zyp> which makes it a bit too much work to make it worthwhile
2020-02-16T01:57:55 < zyp> but what if there were a module with a usb-c socket, a mcu and analog switches for the signals? slap it on a board, route usb and swd to it, done

2020-02-16T02:03:52 < zyp> kakimir, assembly files aren't compiled, just assembled and linked
2020-02-16T02:04:01 < zyp> the compiler produces assembly
2020-02-16T02:04:51 < zyp> in other words, no, they are not optimized, assembly is supposed to be a 1:1 translation of the resulting machine code
2020-02-16T02:05:50 < zyp> qyx, hmm, it's also only supported for DFP or DRP
2020-02-16T02:06:14 < zyp> while most devices this will be relevant for are UFP
2020-02-16T02:06:50 < zyp> I wonder if that's a limitation of the standard
2020-02-16T02:09:28 < mawk> the hot and cold flushing phase is starting
2020-02-16T02:09:30 < zyp> no, standard defines both sink and source variants of both debugger and target
2020-02-16T02:09:42 < mawk> someone could do a scientific experiment on me
2020-02-16T02:10:00 < mawk> I think the worst of all is the restless legs syndrome
2020-02-16T02:10:09 < mawk> or the back pain maybe
2020-02-16T02:10:29 < mawk> if you stay still more than 3s the pressure build up in the back and the legs starts to become unbearable; it's not handy to sleep

2020-02-16T05:54:12 < kakigate> you think pulling flash from phones is for mortals?
2020-02-16T05:55:10 < kakigate> I think physically it's hard
2020-02-16T05:55:34 < kakigate> and nowdays all the encryption
2020-02-16T05:57:38 < kakigate> http://www.datarecoveryspecialists.co.uk/blog/flash-data-recovery-chip-off-and-jtag
2020-02-16T05:57:44 < kakigate> look at those chips
2020-02-16T05:58:27 < rajkosto> i did it 
2020-02-16T05:58:33 < rajkosto> with a shingle heat gun
2020-02-16T05:58:46 < rajkosto> the smell of the epoxy keeping the bga emmc on was death/cancer
2020-02-16T06:00:21 < rajkosto> and then i had to deadbug it with super thin enamel wire
2020-02-16T06:00:40 < rajkosto> it was a samsung galaxy s2 with no encryption tho
2020-02-16T06:02:40 < kakigate> >s2
2020-02-16T06:02:56 < rajkosto> was still epoxy filled for rigidity tho
2020-02-16T06:03:01 < rajkosto> which is what made it hard to desolder
2020-02-16T06:07:42 < Cracki> watched a jessa jones video once ("ipad rehab"). she had an iphone that dropped into salt water in 2016 and now they wanted the data. encryption keys seem to be stored on some eeprom chip that got zapped so there was no hope, even if the flash was readable.
2020-02-16T06:10:35 < rajkosto> for this one, once i connected it to sd card shell and inserted that into adapter, it had a GPT partition table and just ext4
2020-02-16T06:12:55 < jadew> why do they do that btw?
2020-02-16T06:13:06 < jadew> why encrypt data like you're a fucking FBI agent
2020-02-16T06:13:21 < rajkosto> so if you lose your phone someone cant dump your nudie pics
2020-02-16T06:13:34 < jadew> but if you lose your phone, they still can
2020-02-16T06:13:42 < rajkosto> nope it should be locked
2020-02-16T06:13:47 < jadew> ah, I don't keep mine locked
2020-02-16T06:14:10 < kakigate> https://www.ebay.com/itm/NAND-TSOP32-40-48-SOP44-SOP56-adapter-for-TL866CS-A-TL866II-plus-programmer/323345390282?hash=item4b48e31aca:g:EQoAAOSwfPFbRxYc
2020-02-16T06:18:36 < Cracki> my guess for the encryption stuff is (1) so apple can claim they're about protecting users (lol) (2) data recovery is made impossible so ppl don't have a reason to ask for schematics and tools to fix those things
2020-02-16T06:19:47 < jadew> and so they are forced to use cloud storage
2020-02-16T06:21:42 < doomba> yep because icloud is totally encrypted
2020-02-16T06:22:55 < doomba> tier 2 advisors would always be like "this file? or that file? which one? which photo? ah that one sure it's restored." in my escalations when i worked with apple
2020-02-16T06:23:17 < doomba> and i sit there and scratch head like "..... yep. it's TOTALLY encrypted."
2020-02-16T06:26:16 < Cracki> encrypting the device is part of their lockdown/lockin. they want total control over the thing you supposedly "own"
2020-02-16T06:27:35 < Cracki> they also work hard to maintain the fiction that their employees are "trustworthy" and highly trained

2020-02-16T06:28:19 < doomba> tbf you need apple connect id with their hardware

2020-02-16T06:28:34 < doomba> to get on the vpn
2020-02-16T06:28:57 < doomba> and then from there, access to the icloud support software is heavily monitored / tied to your apple connect id
2020-02-16T06:29:12 < doomba> they have a safari plugin thing that does the MFA on it
2020-02-16T06:29:53 < doomba> so even if the employee is not trustworthy, they're gonna know who accessed some celeb's nudes
2020-02-16T06:30:23 < doomba> so it really just comes down to not wanting to go to prison

2020-02-16T06:31:39 < doomba> if you're anyone of importance, it's gonna divert you to a special team of advisors
2020-02-16T06:31:50 < doomba> with clearances and shit probably
2020-02-16T06:31:53 < jadew> who is verifying the guys who wrote the plugin?
2020-02-16T06:32:12 < doomba> everyone
2020-02-16T06:32:22 < Cracki> is it open source
2020-02-16T06:32:28 < doomba> kind of
2020-02-16T06:32:33 < Cracki> so it's not
2020-02-16T06:32:45 < Cracki> "open source" doesn't mean eyeballs
2020-02-16T06:32:45 < jadew> I'm off to bed, night
2020-02-16T06:32:51 < Cracki> bye bye
2020-02-16T06:32:52 < doomba> not like OPEN source but there's an internal community board where advisors can work with engineers on emerging issues
2020-02-16T06:32:57 < doomba> submit reports and stuff like that
2020-02-16T06:33:16 < Cracki> omg "we have a slack"
2020-02-16T06:33:22 < doomba> nah it's more than slack lol
2020-02-16T06:33:30 < doomba> they use xmpp for comms
2020-02-16T06:34:00 < Cracki> I don't trust anyone to run group comms properly
2020-02-16T06:34:21 < doomba> you'd be amazed how many iphones get scooped up / stolen and then sent back to china for "refurbishing" and then sold on aliexpress or wherever
2020-02-16T06:34:45 < doomba> so when you pull up someone's account, you can see everyone who touched that phone. where it's been.
2020-02-16T06:35:04 < doomba> oh... new jersey, china, pakistan, now it's in the UK.
2020-02-16T06:35:15 < doomba> another funny one was
2020-02-16T06:35:34 < doomba> they officially refurbish iphones
2020-02-16T06:35:40 < doomba> like apple refurbished. not some 3rd party.
2020-02-16T06:35:48 < doomba> and sell them to walmart. then walmart sells them as if they're new.
2020-02-16T06:36:12 < rajkosto> apple reusing things ?? insanity
2020-02-16T06:36:12 < doomba> but when those walmart iphone customers call in with issues, you see the history of the phone and where/when it was refurbished. the previous owners... all that.
2020-02-16T06:36:23 < doomba> yet the customer is complaining like "i bought this thing new from walmart"
2020-02-16T06:36:25 < rajkosto> usually they just send it right to the GLASS CRUNCHER so they can claim to be green and recycling
2020-02-16T06:36:41 < doomba> well
2020-02-16T06:37:18 < doomba> p much all hw sold at walmart is factory 2nds, refurbs, or defective shit that has been "refurbished" - and then sold as new.
2020-02-16T06:37:28 < doomba> it's borderline illegal. probably is illegal.
2020-02-16T06:37:45 < doomba> but you'll never prove it. and it's fucking walmart so if you did get proof, you'd get assassinated.
2020-02-16T06:39:25 < doomba> i got in trouble a couple times for accidentally mentioning previous history with a customer.
2020-02-16T06:39:28 < doomba> not paying attention
2020-02-16T06:40:10 < doomba> complaining about the thing not charging or something, and i'll be like "yea i see here it was serviced for that, and it's still doing it?"
2020-02-16T06:40:21 < doomba> "WTF ARE YOU TALKING ABOUT? I JUST BOUGHT THIS AT WALMART. IT'S BRAND NEW."

2020-02-16T06:51:43 < Cracki> he's not, he's a hacker or sth
2020-02-16T06:52:01 < Cracki> the rossmann guy never owned apple products, never worked for them
2020-02-16T06:53:23 < rajkosto> rossman just follows sold repair manuals/schematics to make lots of money in shitty city
2020-02-16T06:58:26 < Cracki> "sold" on the dark net and stuff
2020-02-16T06:58:56 < rajkosto> nah, apple is large enough that theres a lotta people and a lotta need for it, so you can just "buy" them
2020-02-16T06:59:07 < Cracki> he's been indicating that ppl inside of apple send him unobtainium chips such as the ISL 9240 that intersil is forbidden from selling to anyone but apple
2020-02-16T06:59:30 < Cracki> schematics too, which they never release officially
2020-02-16T06:59:41 < rajkosto> of course they never release officially but they end up places
2020-02-16T07:00:14 < Cracki> he does make tons of money with some easy fixes but he's smart enough to operate a multimeter and exclude subsystems that work, or don't work because of something else that's broken
2020-02-16T07:00:29 < Cracki> and he's smart enough to employ ppl even smarter than him
2020-02-16T07:00:33 < rajkosto> yes but he uses "donor" boards even for simple common value SMDs...
2020-02-16T07:00:40 < Cracki> because it's fucking convenient
2020-02-16T07:00:43 < Cracki> saves time
2020-02-16T07:00:59 < Cracki> and that translates into money
2020-02-16T07:01:07 < rajkosto> takes longer to desolder than to pick out of a box
2020-02-16T07:01:42 < Cracki> he looks reasonably quick doing that, and he doesn't have to look up values in the board viewer
2020-02-16T07:01:42 < rajkosto> and you cant reuse that part if you lose it from one donor board, gotta fish out another
2020-02-16T07:02:37 < rajkosto> the whole youtube thing is super awkward too
2020-02-16T07:03:05 < Cracki> explain that.
2020-02-16T07:11:40 < kakigate> paypal helios interface doesnt load for payments in ebay

2020-02-16T14:05:18 < PaulFertser> mawk: I saw you discussing error handling recently. Here's a (I guess lame) example of my take on that: http://paste.debian.net/1130811/
2020-02-16T14:06:09 < PaulFertser> mawk: basically, every action in iwdata do can fail but it should get handled transparently.
2020-02-16T14:07:49 < PaulFertser> (the closeFd is the ugliest line there but apparently it's a silly limitation/error of the netlink library I'm using)
2020-02-16T14:10:08 < PaulFertser> srk: ^^ you might want to teach me how to use Haskell there in a less rookie way.
2020-02-16T14:11:53 < Steffanx> rightToMaybe.
2020-02-16T14:19:11 < Cracki> from afar that could be perl or ruby
2020-02-16T14:19:40 < Steffanx> what if its valid perl.

2020-02-16T14:53:43 < PaulFertser> Each step there can fail but thanks to >>= or do notation the failure will be propogated to wherever I'm ready to handle it. Kinda like exceptions but in a clean way (basically, return value carries either real result or error marker (or if you want a specific error) and the next thing in >>= or net line in do block won't be getting evaluated if there's an error on the previous step.

2020-02-16T14:59:51 < mawk> yes that's very clean
2020-02-16T15:01:57 < mawk> in C I use goto for error handling
2020-02-16T15:02:24 < zyp> pretty much the only justifiable use of goto in C
2020-02-16T15:02:53 < Cracki> any use of goto is justified if it enrages someone :P
2020-02-16T15:03:52 < mawk> lol
2020-02-16T15:05:14 < mawk> let's call the hospital
2020-02-16T15:05:33 < mawk> I will tell that if they don't give me the magical pills I'll have to skip work and I'll get fired
2020-02-16T15:05:37 < mawk> that will surely work
2020-02-16T15:05:41 < Cracki> srsly goto for orderly cleanup of errors makes a lot of sense and I haven't seen languages with exceptions deal with that nicely
2020-02-16T15:06:28 < Cracki> either you have nested try-except-finally blocks, or you stuff all that in destructors and model everything as an object (RAII)
2020-02-16T15:06:49 < Cracki> good luck
2020-02-16T15:07:25 < Cracki> there ought to be ways to get your prescription filled around the clock
2020-02-16T15:07:33 < zyp> yeah? RAII is good
2020-02-16T15:07:46 < mawk> the pharmacy has the prescription paper, and it's closed
2020-02-16T15:08:18 < Cracki> why do they hold on to it
2020-02-16T15:08:23 < zyp> cleaning up is tedious boilerplate, RAII makes cleanup implicit
2020-02-16T15:08:40 < Cracki> they don't hand out the whole script at once, do they
2020-02-16T15:08:42 < zyp> mawk, you guys still get prescriptions on paper?

2020-02-16T15:08:56 < zyp> haha
2020-02-16T15:09:08 < mawk> yes it's like a small prescription every 2 weeks Cracki 
2020-02-16T15:09:09 < BrainDamage> here prescriptions are both paper and digital
2020-02-16T15:09:13 < mawk> faxed directly to the pharmacy
2020-02-16T15:09:44 < zyp> BrainDamage, how do your digital prescriptions work?
2020-02-16T15:10:07 < BrainDamage> to each prescription there's a code associated, and repeated as barcode
2020-02-16T15:10:13 < Cracki> if they insist on paper, I'd model this as one script with a table where any pharmacy can fulfill a part, then note that and sign for it
2020-02-16T15:10:30 < BrainDamage> then an online db with the info mirrored
2020-02-16T15:10:46 < Steffanx> dont you have your "EPD" yet, mawk? :P
2020-02-16T15:10:48 < mawk> in france for the secure prescription it was still on paper
2020-02-16T15:10:52 < BrainDamage> the code is just a UUID
2020-02-16T15:11:00 < mawk> but secured paper, made by the same company that does bank notes apparently
2020-02-16T15:11:10 < mawk> what's EPD Steffanx ?
2020-02-16T15:11:11 < zyp> here there's a national db with all prescriptions
2020-02-16T15:11:29 < zyp> so after going to the doctor, I just go to any pharmacy and show my ID
2020-02-16T15:11:34 < mawk> nice
2020-02-16T15:11:44 < Steffanx> "Elektronisch patiëntendossier".
2020-02-16T15:11:54 < BrainDamage> I can get the list of my prescriptions online and print them
2020-02-16T15:12:10 < BrainDamage> but I don't think I've ever tried going to the pharmacy with just my code
2020-02-16T15:12:13 < mawk> I guess it's different for my kind of meds Steffanx 
2020-02-16T15:12:22 < mawk> they're terrfied of double-fullfilment of the script
2020-02-16T15:12:27 < Steffanx> awh
2020-02-16T15:12:29 < zyp> I don't get any paper from the doctor to take to the pharmacy
2020-02-16T15:12:31 < mawk> and of me abusing or reselling the pills
2020-02-16T15:12:38 < zyp> it's all tied to my ID
2020-02-16T15:12:52 < BrainDamage> in principle they could do the same here
2020-02-16T15:12:55 < mawk> but I still don't have med insurance, they will start to notice
2020-02-16T15:13:03 < mawk> it expired 2 months ago
2020-02-16T15:13:07 < Steffanx> -_-
2020-02-16T15:13:13 < mawk> but since it's cross-country they don't see it immediately
2020-02-16T15:13:15 < Steffanx> They will find you no matter way
2020-02-16T15:13:19 < mawk> lol
2020-02-16T15:13:21 < Steffanx> what
2020-02-16T15:13:24 < mawk> I'll get one next month
2020-02-16T15:13:31 < mawk> well it's my French insurance
2020-02-16T15:13:35 < Steffanx> Dutch dont do "free".
2020-02-16T15:13:55 < mawk> don't worry
2020-02-16T15:14:00 < mawk> I can hide well
2020-02-16T15:14:01 < zyp> medical insurance as something you have to get is still weird to me
2020-02-16T15:14:07 < mawk> yeaha
2020-02-16T15:14:09 < mawk> me too
2020-02-16T15:14:12 < zyp> over here it's something you just have by existing
2020-02-16T15:14:21 < Steffanx> but you do pay for it
2020-02-16T15:14:24 < Cracki> how's that different?
2020-02-16T15:14:39 < Cracki> even if you "just have" it, you do have a choice among options, no?
2020-02-16T15:15:02 < zyp> no
2020-02-16T15:15:06 < mawk> in france no
2020-02-16T15:15:08 < Cracki> or do you automatically "fall into" some default every time there's a "hole"
2020-02-16T15:15:14 < Cracki> hm
2020-02-16T15:15:18 < BrainDamage> here health care is instutionalized
2020-02-16T15:15:19 < mawk> you have to pay to the organism relative to your profession
2020-02-16T15:15:26 < Cracki> so, truly state-run then
2020-02-16T15:15:37 < mawk> yes
2020-02-16T15:15:51 < Cracki> or regulated to be choiceless
2020-02-16T15:15:53 < zyp> in norway every resident is a member of «folketrygden» which provides health coverage for everybody
2020-02-16T15:16:07 < Cracki> sounds very civilized
2020-02-16T15:16:23 < Cracki> pls invade germany and teach this to us
2020-02-16T15:17:05 < Steffanx> does norway even have a proper army?
2020-02-16T15:17:07 < BrainDamage> same here, if you're resident you're covered by healthcare, and even if you're not resident you'll get any ER treatment for free if it happens here
2020-02-16T15:17:25 < zyp> of course, there are some private health insurances also, but those only matter if you want private healthcare outside of what the public system already offers
2020-02-16T15:17:28 < PaulFertser> You'll be surprised how every single thing you buy in Norway is so much more expensive than in DE.
2020-02-16T15:17:33 < zyp> so that's not super common, I don't bother with that
2020-02-16T15:17:52 < zyp> PaulFertser, even adjusted for purchasing power?
2020-02-16T15:17:53 < mawk> in france since 5 years private insurance is allowed, but 0 companies tried it
2020-02-16T15:18:02 < mawk> because it's extremely difficult to get outside the state system
2020-02-16T15:18:17 < mawk> I guess it comes from european ruling
2020-02-16T15:18:18 < Steffanx> i bet electricity is cheaper in norway.
2020-02-16T15:18:21 < BrainDamage> there's private healthcare here as well, typically only used if you want immediate scheduling
2020-02-16T15:18:23 < zyp> PaulFertser, stuff in norway is expensive for sure, but we're paid well too
2020-02-16T15:18:49 < BrainDamage> for ER you can even go to a private clinic, and state will still pay you
2020-02-16T15:18:59 < Cracki> salary/wage needs to be expressed in terms of loaves of bread per hour
2020-02-16T15:19:34 < BrainDamage> I have toyed the idea of a fictitious currency where the exchange rate is defined as the cost of life in each country
2020-02-16T15:19:49 < BrainDamage> then you can compare easily wages and cost of goods
2020-02-16T15:20:38 < zyp> how do you define cost of life?
2020-02-16T15:20:54 < BrainDamage> usually the state itself defines it, to calculate inflation
2020-02-16T15:21:09 < BrainDamage> at least for italy, there's a set of basic goods for which the price is tracked
2020-02-16T15:21:21 < Cracki> you can compare prices of basic foods
2020-02-16T15:21:32 < Cracki> or rent prices
2020-02-16T15:21:51 < BrainDamage> not just food, the "panier" as it's called here include things like transportation costs, rent, etc
2020-02-16T15:22:12 < PaulFertser> zyp: I'm just saying how it looks for a foreign tourist
2020-02-16T15:22:14 < zyp> https://en.wikipedia.org/wiki/Big_Mac_Index
2020-02-16T15:22:31 < Cracki> *cough*
2020-02-16T15:22:39 < zyp> PaulFertser, yes, I'm on the other side of that, it's pretty cheap for me to travel anywhere
2020-02-16T15:22:54 < BrainDamage> you cannot use a single item because of regional variations
2020-02-16T15:23:16 < Cracki> ugh, muricans and their inverted units. "how many burgers can you get for 50 usd"
2020-02-16T15:24:01 < BrainDamage> it's probably the same reasoning while fuel usage is l per 100km rather than km/l
2020-02-16T15:24:19 < Cracki> yes, they're just weirdly built in the head
2020-02-16T15:24:44 < jadew> here state run health care is lacking in many areas
2020-02-16T15:24:56 < jadew> so private health care is actually a good option
2020-02-16T15:25:10 < jadew> and the problem is you can't opt out of paying for public health care
2020-02-16T15:25:48 < zyp> jadew, well, it's not like the public system would get any less lacking if people could opt out of financing it
2020-02-16T15:26:10 < jadew> zyp, yeah, but at least you could use that money to get better health care for yourself
2020-02-16T15:26:27 < jadew> everything that is state run is shit
2020-02-16T15:26:34 < zyp> because that's working so well for the US?
2020-02-16T15:26:35 < jadew> or worse than if it was privately run
2020-02-16T15:26:55 < BrainDamage> here you have the option to go private for anything, even retirement that's state run you can opt-out and chose a private one
2020-02-16T15:27:02 < jadew> as en example, the municipality decided that no garbage collection agencies can exist anymore and they'll pick up the garbage from now on
2020-02-16T15:27:07 < BrainDamage> you're only mandated to have _one_, but you're free on the choice
2020-02-16T15:27:08 < jadew> well, they don't do it as often
2020-02-16T15:27:09 < zyp> if everything state run is shit, maybe you should reconsider who you elect to run the state
2020-02-16T15:27:15 < jadew> and there's garbage everywhere now
2020-02-16T15:27:34 < jadew> BrainDamage, yeah, that sounds sane
2020-02-16T15:28:00 < jadew> also, the price of garbage collection has doubled for private companies
2020-02-16T15:28:26 < jadew> because it's mandatory to switch to the state's garbage collection thing
2020-02-16T15:28:29 < Cracki> different types of pressure. state: remove the politicians, or go gulag. free market: go to competitor, or become a competitor, or suffer under a monopoly.
2020-02-16T15:28:55 < jadew> food time
2020-02-16T15:28:57 < jadew> ttyl
2020-02-16T15:29:16 < Cracki> many big macs
2020-02-16T15:29:27 < BrainDamage> the problem with both is that you're born into an existing situation
2020-02-16T15:29:56 < BrainDamage> and while you can influence it with your choices, the starting conditions can be hard to break from
2020-02-16T15:30:23 < Cracki> very
2020-02-16T15:30:43 < BrainDamage> eg poverty is mostly self sustaining ( less access to education, live in places with high criminality, etc )
2020-02-16T15:30:43 < Cracki> and even if the situation is good, it can be worsened by bad actors
2020-02-16T15:31:24 < Cracki> when ppl take civilization for granted, it's most vulnerable.
2020-02-16T15:33:56 < Steffanx> ok
2020-02-16T15:34:26 < mawk> the hospital agreed !
2020-02-16T15:34:30 < mawk> victory
2020-02-16T15:34:42 < mawk> let's ride some bike and get back to baseline
2020-02-16T15:34:51 < Steffanx> So do you actually need it mawk?
2020-02-16T15:34:56 < mawk> of course
2020-02-16T15:35:13 < Steffanx> ofcourse or "I think i do"?
2020-02-16T15:35:29 < mawk> diarrhea, back pain, restless legs syndrome, alternating between hot and cold, sweating, very low motivation
2020-02-16T15:35:34 < mawk> that's after 24h
2020-02-16T15:35:37 < mawk> then it gets worse
2020-02-16T15:35:59 < mawk> methadon withdrawal is actually worse than that of heroin
2020-02-16T15:36:01 < Steffanx> Isnt stopping cold turkey a experience of a life time?
2020-02-16T15:36:03 < BrainDamage> how long will it take to wean off it?
2020-02-16T15:36:11 < Steffanx> *an
2020-02-16T15:36:12 < mawk> a few weeks
2020-02-16T15:36:19 < mawk> it's not feasible
2020-02-16T15:36:25 < mawk> methadone has such a long half life
2020-02-16T15:36:45 < mawk> heroin has a few hours of half life, it's easier to kick out cold turkey
2020-02-16T15:36:56 < mawk> also when doing it like that the risk of relapse is very high
2020-02-16T15:37:04 < mawk> no sane addictologist would recommend that
2020-02-16T15:37:21 < Steffanx> even when  you're forced to?
2020-02-16T15:37:37 < Steffanx> like imprisoned. 
2020-02-16T15:38:01 < mawk> I think that'd be a good case of torture
2020-02-16T15:38:13 < mawk> I don't think EU prisons would let me without treatment
2020-02-16T15:38:14 < Steffanx> self-torture.
2020-02-16T15:38:45 < Steffanx> so how long before you are done with all this?
2020-02-16T15:38:50 < BrainDamage> how does it work then, are you essentially addicted for life or is there some sort of schedule to gradually lower the dose?
2020-02-16T15:40:30 < mawk> a few years probably Steffanx 
2020-02-16T15:40:35 < Steffanx> oof
2020-02-16T15:40:46 < mawk> steepest descent is 2.5mg/month or something, and I'm at 65
2020-02-16T15:40:58 < mawk> but I don't like steep
2020-02-16T15:41:18 < mawk> with my french doctor it was me who was asking for dose lowering BrainDamage 
2020-02-16T15:41:31 < mawk> because that doc thought the risk of relapse is very low doing that
2020-02-16T15:41:33 < Steffanx> that's not how its going to work in dutchland for sure
2020-02-16T15:41:42 < mawk> here in Netherlands well I don't know, the doc doesn't speak english
2020-02-16T15:41:47 < Steffanx> wut?
2020-02-16T15:41:50 < mawk> he just signed the prescription
2020-02-16T15:41:51 < Steffanx> time to find a new doc
2020-02-16T15:41:52 < mawk> yeah
2020-02-16T15:41:55 < mawk> lol
2020-02-16T15:42:05 < Steffanx> old guy?
2020-02-16T15:42:13 < mawk> arabic guy
2020-02-16T15:42:16 < Steffanx> wut
2020-02-16T15:42:22 < mawk> he speaks a lot of languages
2020-02-16T15:42:23 < Steffanx> does he even speak dutch then?
2020-02-16T15:42:28 < mawk> russian, urdu, dutch, arabic
2020-02-16T15:42:31 < mawk> yeah
2020-02-16T15:42:38 < mawk> but not english
2020-02-16T15:42:49 < Steffanx> lol
2020-02-16T15:43:00 < mawk> so he's speaking netherglish and I half understand what he says s
2020-02-16T15:43:03 < mawk> but he doesn't understand me
2020-02-16T15:43:41 < Steffanx> intersting

2020-02-16T15:55:44 < Steffanx> when i was 13 I was like: Smoking.. nah ty
2020-02-16T15:55:53 < Steffanx> drugs: HAH. No.
2020-02-16T15:56:04 < mawk> well I never really smoked joints not drinked alcohol
2020-02-16T15:56:34 < mawk> I was more in the better living through chemistry mindset
2020-02-16T16:01:06 < specing> mawk: how did you end up on methadone?
2020-02-16T16:01:18 < specing> fucked your back up?

2020-02-16T16:08:05 < karlp> no, he started with heroin
2020-02-16T16:08:20 < Steffanx> the good stuff
2020-02-16T16:08:25 < mawk> nobody gives methadone for pain now I think
2020-02-16T16:08:29 < mawk> it's a bit lame
2020-02-16T16:08:36 < Steffanx> why arent you on your bike yet?
2020-02-16T16:08:37 < mawk> not exactly heroin, it was too expensive
2020-02-16T16:08:43 < mawk> I'm walking
2020-02-16T16:08:51 < mawk> the weather is nicer than I thought
2020-02-16T16:09:38 < catphish> i had no idea methadone was ever used for anything other than opiate addiction
2020-02-16T16:09:59 < karlp> not much these days, it used to be a hospital painkiller I think though
2020-02-16T16:10:08 < mawk> yes
2020-02-16T16:10:42 < mawk> and well at one point my wallet was unhappy with the opiate consumption so I asked some treatment center
2020-02-16T16:10:46 < catphish> safer than heroine i guess
2020-02-16T16:10:49 < mawk> also it doesn't play well with a gf
2020-02-16T16:10:53 < mawk> opiates are very safe
2020-02-16T16:10:56 < mawk> when they are pure
2020-02-16T16:11:42 < catphish> oh, it's synthetic, interestinf
2020-02-16T16:12:04 < catphish> by safer, i largely mean less likely to cause addiction
2020-02-16T16:12:49 < catphish> idk though, never taken any opiate myself
2020-02-16T16:13:18 < catphish> or is it opioids? i don't even know what they're called!
2020-02-16T16:14:11 < mawk> opioid is the chemical class
2020-02-16T16:14:23 < mawk> opiates are mu-opiate receptor agonists
2020-02-16T16:14:31 < mawk> some opioids are not opiates
2020-02-16T16:14:41 < mawk> like dextromethorphane
2020-02-16T16:14:51 < mawk> or some anti diarrhea agents
2020-02-16T16:17:41 < mawk> heroin is hemisynthetic as well
2020-02-16T16:17:57 < mawk> eg reacting morphine with acetic anhydride in an oven
2020-02-16T16:18:09 < mawk> but not usually pure lol

2020-02-16T17:10:29 < mawk> that can only be fake
2020-02-16T17:10:38 < jadew> heh
2020-02-16T17:10:42 < mawk> also Simone is a grandma name
2020-02-16T17:11:34 < jadew> they also have an interview with the head of a crematorium I think
2020-02-16T17:13:03 < jadew> he says they're working non-stop, with 11 furnaces and while he refused to give actual numbers, he did say it takes 50 minutes/body
2020-02-16T17:13:16 < jadew> which works out to ~316 bodies/day
2020-02-16T17:14:13 < mawk> maybe they're dying of hunger from lockdown
2020-02-16T17:14:32 < jadew> that probably doesn't help, yeah
2020-02-16T17:18:43 < Steffanx> And that the usual rate?
2020-02-16T17:18:53 < jadew> no, it's about 5 times the usual rate
2020-02-16T17:19:08 < jadew> so roughly 250 new bodies per day for this one place
2020-02-16T17:19:22 < jadew> and it's not the only one, and the other ones seem to have even more workload
2020-02-16T17:19:26 < Steffanx> Whatever. Not going to speculate over random internet numbers :P
2020-02-16T17:20:22 < Steffanx> Based on some interview of some random guy in a language i dont understand
2020-02-16T17:20:31 < jadew> it's an interview... but yeah... it's anonymized
2020-02-16T17:20:59 < jadew> I agree, you can't trust it by itself, but they back it up with social media videos

2020-02-16T17:22:20 < jadew> according to that interview 60% died at home
2020-02-16T17:23:26 < mawk> lol the vid of the hospital
2020-02-16T17:23:27 < jadew> nvm, he states some numbers and they're not what I said
2020-02-16T17:23:43 < mawk> it's a konzentrationkamp
2020-02-16T17:23:47 < mawk> not an hospital
2020-02-16T17:24:09 < jadew> mawk, yeah
2020-02-16T17:24:23 < jadew> so the numbers the guy states are 127 bodies on the previous day
2020-02-16T17:24:29 < jadew> which he says it's the worst yet
2020-02-16T17:25:13 < jadew> so I guess they're not really working at full capacity (according to his own numbers)
2020-02-16T17:25:42 < mawk> in France a pharmacy would never let me have methadone based only on my testimony lol
2020-02-16T17:25:42 < jadew> that still makes it 100/day in a single center like this
2020-02-16T17:25:48 < mawk> good thing I'm in dutchland
2020-02-16T17:25:58 < mawk> but in france they're open on weekend, less lazy

2020-02-16T17:27:01 < jadew> you like it better than France so far?
2020-02-16T17:27:17 < mawk> it's different
2020-02-16T17:27:23 < mawk> for the city itself yeah I guess
2020-02-16T17:27:30 < mawk> I was not in the best neighborhood of paris
2020-02-16T17:27:37 < mawk> for the people,I don't know
2020-02-16T17:27:42 < mawk> I'll wait until I speak dutch
2020-02-16T17:27:51 < mawk> so I can know if they talk behind my back
2020-02-16T17:28:34 < mawk> I'm waiting in the hospital lobby for the meds to kick in to be able to walk faster than 50cm/minute again
2020-02-16T17:29:14 < mawk> and for the culture well it's rich enough
2020-02-16T17:29:20 < mawk> can't say that about the gastronomy though
2020-02-16T17:29:34 < mawk> a surprising amount of stuff is named in broken french in the supermarket
2020-02-16T17:29:47 < mawk> sells better
2020-02-16T17:30:14 < mawk> LE MAYONNAISE À LE TRUFFE 100% FRANÇAIS
2020-02-16T17:30:17 < jadew> I didn't like the food I had in france
2020-02-16T17:30:27 < mawk> I guess good french food is expensive
2020-02-16T17:30:31 < mawk> all the rest is tourist trap
2020-02-16T17:30:37 < jadew> a lot of raw fish
2020-02-16T17:30:42 < mawk> I never eat in french restaurant
2020-02-16T17:30:44 < jadew> and other sea food I don't enjoy
2020-02-16T17:30:48 < mawk> unless it's expensive, but I'm poor
2020-02-16T17:31:12 < jadew> I ate well at Disney
2020-02-16T17:31:16 < mawk> lol
2020-02-16T17:31:20 < jadew> but it wasn't french food
2020-02-16T17:31:21 < mawk> they are american restaurants
2020-02-16T17:31:24 < jadew> yeah
2020-02-16T17:31:24 < mawk> yeah

2020-02-16T17:46:48 < jadew> so the number these reporters calculated were of about 8k deaths from nCoV
2020-02-16T17:47:38 < jadew> and according to the US CDC, they know the numbers are underestimated because mathematical models based on the number of infections in other places, are suggesting the same thing

2020-02-16T18:01:43 < jadew> there was a death in france
2020-02-16T18:02:24 < jadew> so the idea that if well treated (like in a western hospital) is enough to get you well, is out the door
2020-02-16T18:02:32 < jadew> they only had 12 cases, 1 died, 4 recovered
2020-02-16T18:03:42 < Steffanx> Perhaps. But she was 80, got sick in china. And i wonder how bad she was when she got admitted.
2020-02-16T18:03:46 < specing> so its 20% mortality?
2020-02-16T18:04:06 < Steffanx> and then.. who says she would have survived the next common cold :P
2020-02-16T18:04:07 < jadew> Steffanx, ah, didn't know that
2020-02-16T18:06:12 < catphish> how do i know when i have chinavirus and the end is near

2020-02-16T20:29:19 < mawk> harmfulm
2020-02-16T20:32:56 < jpa-> maybe IAR or some other crappy compiler didn't have stdint.h
2020-02-16T20:38:33 < jpa-> writing out huffman stream byte-per-byte seems a bit inefficient on a 32-bit architecture
2020-02-16T20:47:57 < Steffanx> not even proper definitions. it should be u8,u16 etc.
2020-02-16T20:53:16 < mawk> nnnn
2020-02-16T20:53:22 < mawk> uint16_t and so on is the way to go
2020-02-16T20:53:25 < mawk> it's POSIX defined in stdint.h
2020-02-16T20:53:38 < mawk> or maybe even C standard defined
2020-02-16T20:54:30 < specing> naaah
2020-02-16T20:54:33 < specing> it should be  type u8 is new unsigned; for u8'Size use 8;
2020-02-16T20:57:41  * Steffanx gives mawk some bool_t for his standard.
2020-02-16T20:57:53 < mawk> stdbool.h
2020-02-16T20:57:58 < mawk> in the standard too
2020-02-16T20:58:03 < mawk> there is the primitive type _Bool in C99
2020-02-16T20:58:07 < mawk> aliased to bool
2020-02-16T20:58:35 < mawk> then true is (_Bool)1 and false is (_Bool)0
2020-02-16T20:58:37 < mawk> pure C99
2020-02-16T20:59:23 < Steffanx> > bool_t.

2020-02-16T22:20:45 < kakimir> I cannot wrap my head around fastboot
2020-02-16T22:24:08 < kakimir> if SoC rom has simple loader that loads "fastboot" ie. from pc to there and branches into it
2020-02-16T22:24:27 < kakimir> if SoC rom has already "fastboot"
2020-02-16T22:25:16 < kakimir> or if "fastboot" is just a protocol
2020-02-16T22:34:13 < kakimir> apparently SoC only does "bootdownload" with very simple protocol
2020-02-16T22:36:09 < kakimir> and your or vendor's program provides some minimal program that has more capatibilities ie. access nand

2020-02-17T01:00:27 < qyx> zyp: bq25601 looks interesting to backup the 5V backplane bus
2020-02-17T01:00:45 < qyx> it has a bidirectional buck/boost for charging/otg mode
2020-02-17T01:01:03 < qyx> the only problem I see is that the transition between the two takes 30ms minimum
2020-02-17T01:01:45 < qyx> it can track USB input voltage (backplane 5V bus) too to limit the charging current
2020-02-17T01:02:20 < qyx> so the current is lowered when there is not enough power to recharge the battery
2020-02-17T01:03:07 < qyx> but as it is a sync buck/boost, probably a OR-ing controller would be needed on the output
2020-02-17T01:11:44 < zyp> nice
2020-02-17T01:13:02 < zyp> I'm thinking at some point I might experiment with a software controlled switching reg
2020-02-17T01:13:09 < qyx> yeah that too
2020-02-17T01:13:13 < qyx> but atm I am lazy
2020-02-17T01:13:29 < zyp> atm I don't really have a need for battery backup

2020-02-17T01:22:33 < zyp> dunno, I feel I learned most of what I know outside of school
2020-02-17T01:24:03 < zyp> and I don't really remember doing much with quartus in school
2020-02-17T01:24:34 < zyp> I remember we had some cpld devboard, and then we loaded up quartus and played with a few examples, but I think that was it
2020-02-17T01:26:07 < invzim> if you're using vhdl, sigasi can save you a little compile time if you're as bad at it as I am :)
2020-02-17T01:27:02 < zyp> I found verilog syntax to be less verbose than vhdl, so that's what I got started with, way back
2020-02-17T01:28:17 < zyp> but the last time I touched an fpga I used migen, which is a lot more pleasant than either
2020-02-17T01:28:57 < zyp> so I don't really envision doing anything other than migen/litex if I do more fpga stuff

2020-02-17T01:32:58 < zyp> anyway, I get the impression that symbiflow is working great for both ice40 and ecp5, so I ordered a couple of those cheap ecp5-based led driver cards: https://github.com/q3k/chubby75
2020-02-17T01:33:41 < qyx> what about the python stuff?
2020-02-17T01:33:49 < zyp> what about what?
2020-02-17T01:35:26 < zyp> https://twitter.com/enjoy_digital/status/1220004677217144834 <- people already have a litex-based system with risc-v and gigabit ethernet running on that shit
2020-02-17T01:35:48 < zyp> so I figure I could do some fun and/or useful stuff with it
2020-02-17T01:38:49 < qyx> there was a lib/framework for programming ICE in python
2020-02-17T01:39:01 < qyx> forgot the name
2020-02-17T01:39:44 < zyp> e.g. for some of the stuff I do at work I could use some shit to bridge between a plain LAN and a realtime network (queueing packages and fitting them into timeslots)
2020-02-17T01:43:13 < zyp> I'm running UDP traffic for config/bootloading/monitoring/testing next to the realtime traffic on the realtime network, and right now I only got a plain router in between
2020-02-17T01:44:42 < zyp> works okay enough at a low rate, but too much starts interfering with the realtime traffic since the router doesn't respect the timeslots

2020-02-17T05:41:05 < mrec> seems like I have to run st-flash erase before uploading the firmware to the stm32l0 nucleo board
2020-02-17T05:41:17 < mrec> directly uploading it with write does not update the image
2020-02-17T05:41:18 < dongs> you generally need to erase before writing yes
2020-02-17T05:41:34 < mrec> I would expect that write is doing that
2020-02-17T05:41:35 < mrec> Flash page at addr: 0x08004500 erased
2020-02-17T05:41:36 < dongs> isnt that the case everywehre?
2020-02-17T05:41:53 < dongs> whjats st-flash, is that using SWD or bootrloader?
2020-02-17T05:41:59 < mrec> swd
2020-02-17T05:42:19 < mrec> write does not erase properly
2020-02-17T05:42:40 < mrec> 2020-02-17T04:40:54 INFO common.c: Finished erasing 139 pages of 128 (0x80) bytes
2020-02-17T05:43:01 < dongs> maybe it hasnt been updated to page size/layout of newer chips
2020-02-17T05:43:05 < mrec> (that's what write is doing, before sending the new image to the controller)
2020-02-17T05:43:12 < zyp> dongs, st-flash is the old texane shit that nobody uses anymore
2020-02-17T05:43:17 < dongs> yeah thats what i thoguht
2020-02-17T05:43:23 < dongs> why the fuck is he using it then
2020-02-17T05:43:51 < zyp> dunno, saw somebody suggest openocd earlier
2020-02-17T05:44:04 < dongs> ST does make some lunix flasher shit now
2020-02-17T05:44:11 < dongs> STM32CUBEPROGRAMMER or osemeshit
2020-02-17T05:44:37 < zyp> oh, yeah, I've used that
2020-02-17T05:44:56 < zyp> had to use it to load cpu2 firmware for stm32wb
2020-02-17T05:50:05 < zyp> dongs, by the way, when can I expect any news on my cables?
2020-02-17T05:51:26 < mrec> doesn't matter it works that weird way
2020-02-17T05:59:09 < dongs> zyp, take $today and + 14 days and it will be at least that
2020-02-17T05:59:15 < dongs> chinagirl still not in sz, and canot leave current place
2020-02-17T05:59:22 < dongs> and once she does arrive to SZ she can't go anywhere for 2 weeks
2020-02-17T06:00:39 < dongs> like i said, i think 'weird way' is due to it not having correct page map
2020-02-17T06:00:43 < dongs> for new(er) chips
2020-02-17T06:00:52 < dongs> erase prolly does a mass erase and doenst care about page count
2020-02-17T06:01:00 < dongs> erase+write does page at a time and is prolly wrong
2020-02-17T06:03:25 < mrec> st-flash is seriously a piece of shit
2020-02-17T06:03:51 < mrec> it just crashed the nucleo board which is connected remotely of course and I don't have access to it
2020-02-17T06:04:11 < dongs> didnt someone already told you to use openocd
2020-02-17T06:05:39 < mrec> ok openocd is able to recover it
2020-02-17T06:21:19 < mrec> those tools are all sick
2020-02-17T06:21:33 < mrec> even after years they don't work properly
2020-02-17T06:21:53 < mrec> uploading firmware to an stm32 seems to be magic for some developers
2020-02-17T06:22:15 < mrec> man if my firmware tools would work so crappy I'd get old before the first device works.
2020-02-17T06:22:53 < mrec> openocd won't program the device, but I can reset the device with it.
2020-02-17T06:23:31 < mrec> that's a good example how to make science out of something that is not even worth mentioning it

2020-02-17T06:41:25 < dongs> its fucking lunix
2020-02-17T06:41:31 < dongs> i have *zero* issues with jlink tools on windows
2020-02-17T06:41:46 < dongs> jlink, ozone, keil = amazing combination for development
2020-02-17T06:41:53 < mrec> the windows tools are stable
2020-02-17T06:42:06 < mrec> I did not write a firmware tool for the stm32 by myself yet but might end up doing so
2020-02-17T06:42:28 < mrec> openocd is crap, I expect a simple command not that overengineered stuff
2020-02-17T06:42:45 < dongs> if you dont need to debug but just production flash, just use serial bootloader
2020-02-17T06:42:52 < dongs> if debug, well, just use windows.
2020-02-17T06:42:57 < mrec> if I don't touch that stuff for a half year I'll always rely on some documentation to recall those idiotic commands
2020-02-17T06:43:34 < mrec> my own firmware tools .. 1. I have proper and simple command line help in it foo upload xyz. done no additional scripts or whatever is needed
2020-02-17T06:43:52 < dongs> like i said, if you just need to upload, use serial bootloader. stm32flash works fine.
2020-02-17T06:44:29 < mrec> I'm doing some prototyping remotely using the nucleo board
2020-02-17T06:44:42 < dongs> you can reflash stlink to jlink
2020-02-17T06:44:44 < dongs> on nucleos
2020-02-17T06:44:47 < dongs> then you can use jlink tools
2020-02-17T06:44:58 < dongs> https://www.segger.com/products/debug-probes/j-link/models/other-j-links/st-link-on-board/
2020-02-17T06:47:32 < mrec> well I have my way using st-link so far.. although it needs to erase everything explicitly
2020-02-17T06:48:30 < Cracki> when you have time for experiments, try out jlink. maybe order a china clone if you must. their hw and sw are a real step up from stlink
2020-02-17T06:49:22 < mrec> I think I'm also done with that minicom shit in Linux
2020-02-17T06:50:26 < mrec> those things are so far from the mac and windows tools in terms of usability.. it's unbelievable
2020-02-17T06:53:17 < mrec> minicom comes close to the tools in windows but the menu handling is not good
2020-02-17T07:01:49 < dongs> lol nothing on windows beats teraterm
2020-02-17T07:01:52 < dongs> err nothing on lunix
2020-02-17T07:02:09 < dongs> it works super good for USB shit too cuz it auto-reconnects if you are plugging in many usb>serial devices

2020-02-17T07:10:21 < dongs> you can enter hex / receive shit back in hex
2020-02-17T07:10:38 < dongs> also has separate input boxes so you can queue a few commands and send by one click
2020-02-17T07:10:54 < dongs> idk what the fuck its for officially but works great as a serial terminal
2020-02-17T07:11:38 < Cracki> they say it started for internal use. they have a rs232/485 to ethernet "appliance"
2020-02-17T07:12:11 < Cracki> looks cute, like those things I clicked together 15 years ago in delphi
2020-02-17T07:15:14 < dongs>  anyway i use hercules when i need to send specific hex stuff or teraterm for general serial port/cli stuff
2020-02-17T07:15:54 < dongs> also lets me dick with cts/rts stuff as sometimes i needed to do that

2020-02-17T13:38:49 < srk> USB?
2020-02-17T13:39:11 < zyp> yes, crystalless USB
2020-02-17T13:39:27 < zyp> HSI48 can be autotuned by the CRS module to sync to the USB SOF rate
2020-02-17T13:42:01 < Cracki> can you output hsi on some pin? someone here recently wanted to sync i2s clock to usb and I think he overengineered this instead of just using stm32 facility
2020-02-17T13:42:07 < Cracki> *hsi48
2020-02-17T13:46:06 < Cracki> vampirefrog!
2020-02-17T13:50:07 < jpa-> Cracki: you can output most clocks on MCO pins
2020-02-17T13:50:33 < jpa-> though for i2s master mode, you could probably get it done fully internally also

2020-02-17T14:27:07 < invzim> I need 3v3, 5v0 and 12v0 from ~20V, does it make sense to feed bucks from raw input, or do a 2 stage thing where I feed 12V to the 3v3 and 5v0 bucks?
2020-02-17T14:30:18 < dongs> i would do 2 stage
2020-02-17T14:31:26 < invzim> Will make the pre-buck caps a bit easier for sure

2020-02-17T17:15:16 < srk> missed!
2020-02-17T17:15:46 < dongs> lol they faile d the landing
2020-02-17T17:16:03 < Cracki> where did it go
2020-02-17T17:16:06 < dongs> no idea
2020-02-17T17:16:11 < Ultrasauce> it seemed to be wobbling more than usual before the entry burn
2020-02-17T17:16:16 < Cracki> must have splashed behind the camera
2020-02-17T17:16:17 < Thorn> they did say it was pretty marginal
2020-02-17T17:16:19 < englishman> you could see a cloud off to the right
2020-02-17T17:17:00 < dongs> o yeah defeintiely
2020-02-17T17:17:00 < dongs> lolz
2020-02-17T17:17:19 < Thorn> smoke cloud + water drops on the drone ship camera
2020-02-17T17:17:19 < Cracki> hahah
2020-02-17T17:17:46 < Cracki> around 8:43
2020-02-17T17:18:34 < Cracki> did they command it to "set down" beside the ship because they chickened out...
2020-02-17T17:19:06 < Cracki> smells like one of those first successful landings where they set down on water and let it tip over
2020-02-17T17:19:25 < Thorn> iirc last time the engine shut down a second too early because of fuel depletion and it landed hard
2020-02-17T17:19:45 < Cracki> didn't catch any mention of "marginal" but if that's so, they prolly thought let's not fuck up the ship again :P
2020-02-17T17:19:46 < Thorn> this time the fuel ran out a little earlier still
2020-02-17T17:20:17 < Cracki> how can you tell?
2020-02-17T17:20:51 < Thorn> they said they require more performance for the launch this time
2020-02-17T17:20:53 < Cracki> downlink cut out way too early, that was fishy
2020-02-17T17:20:57 < Cracki> hmhm

2020-02-17T17:21:48 < dongs> 'right next to the drone ship
2020-02-17T17:22:55 < aandrew> too bad they missed the barge
2020-02-17T17:23:18 < Cracki> I would have appreciated a nice fireball too
2020-02-17T17:23:25 < aandrew> yeah I was watching with the kids
2020-02-17T17:23:32 < Thorn> no fuel = no fireball

2020-02-17T19:11:22 < aandrew> hm?
2020-02-17T19:11:30 < aandrew> what do you mean, "how do you guys handle" it
2020-02-17T19:12:52 < invzim> I can make a schematic symbol with pin numbers, not really fool proof
2020-02-17T19:13:04 < invzim> I can make something specific to the OLED
2020-02-17T19:13:14 < invzim> but I really want the part-number etc to be present
2020-02-17T19:15:23 < aandrew> so you want to create a "this connector is for LCD-123A" schematic symbol which uses a generic FFC footprint?
2020-02-17T19:15:47 < aandrew> I've never done that, I just use generic FFC schematic symbols and footprints and label the nets
2020-02-17T19:21:46 < invzim> I have actually done it a few different ways, but want to be consistent
2020-02-17T19:21:51 < rajkosto> i make a new part that uses the same footprints
2020-02-17T19:22:36 < invzim> rajkosto: so external part specific schematic symbol?

2020-02-18T00:58:23 < laurence_> bbc actually made something funny
2020-02-18T00:58:25 < doomba> ye seems after 2010 the movies just went to remakes or woke bullshit
2020-02-18T00:58:25 < laurence_> https://www.bbc.co.uk/iplayer/episode/p082bngf/this-country-series-3-1-a-letter-from-sluggs
2020-02-18T00:58:45 < doomba> there really hasn't been anything that great since the 2000's
2020-02-18T00:58:55 < Ultrasauce> true grit
2020-02-18T00:59:38 < jadew> pretty sure I saw it
2020-02-18T01:00:03 < BrainDamage> ex machina?
2020-02-18T01:00:14 < jadew> saw it
2020-02-18T01:00:19 < jadew> it was interesting
2020-02-18T01:00:19 < Thorn> jadew: listen to some WH40k lore podcasts on youtube
2020-02-18T01:00:51 < Thorn> https://www.youtube.com/playlist?list=PL7NUrRUMQlUTqgibSTXdRu7RZ9vCHqt1g
2020-02-18T01:01:25 < karlp> sound like heresy to me
2020-02-18T01:01:44 < jadew> sounds a lot like history, except it's not real, so it would probably be more educational to listen to some history lectures
2020-02-18T01:03:01 < jadew> I think I'll watch outbreak
2020-02-18T01:04:01 < jadew> and if that fails me, I'll go for the boondock saints, since I remember that one the least

2020-02-18T01:05:41 < doomba> jadew: hesher
2020-02-18T01:09:53 < jadew> anyone saw the last Rambo movie?
2020-02-18T01:10:35 < jadew> triple frontier was good (2019)
2020-02-18T01:14:42 < doomba> triple frontier was kinda dumb
2020-02-18T01:14:49 < doomba> the rambo movie was meh
2020-02-18T01:15:13 < jadew> I just need something with my pizza
2020-02-18T01:15:27 < Steffanx> Sleep?
2020-02-18T01:15:34 < jadew> Dr. Sleep?
2020-02-18T01:15:36 < jadew> saw it
2020-02-18T01:15:50 < Steffanx> No I meant you need to sleep. :P
2020-02-18T01:16:10 < jadew> ah, hehe
2020-02-18T01:16:19 < jadew> unlikely, I woke up at 2 pm
2020-02-18T01:16:20 < Steffanx> China is dead anyway. So no need to be awake
2020-02-18T01:17:04 < jadew> they said they'd be back to work in a couple of days
2020-02-18T01:18:15 < doomba> jadew: you saw hesher?
2020-02-18T01:21:00 < jadew> no
2020-02-18T01:21:10 < jadew> I'll check it out, you seem excited about it
2020-02-18T01:21:20 < jadew> thanks
2020-02-18T01:30:48 < karlp> oh, hesher was not bad.
2020-02-18T01:30:59 < karlp> very much not what I expected, but not sure what I had expected.
2020-02-18T01:31:31 < karlp> now, how to curl, and get the status code _and_ the stdout, because this remote server is dumb as fuck

2020-02-18T01:35:34 < mawk> karlp: for human ? or for script
2020-02-18T01:35:40 < karlp> for script.
2020-02-18T01:35:46 < karlp> -v is enough for humans
2020-02-18T01:36:29 < karlp> -w '{code: %{http_code}, out: %{stdout}}' doesn't work unfortunately, you get "blahblahstdoutblah{code:401, out:}"
2020-02-18T01:38:22 < doomba> you're probably seeing stderr
2020-02-18T01:38:31 < mawk> no that goes to stdout
2020-02-18T01:38:45 < mawk> but I mean you can write the document to a file, and get the code on stdout
2020-02-18T01:38:55 < mawk> or write the document to stderr and the code to stdout
2020-02-18T01:40:01 < karlp> is there a file node for stderr?
2020-02-18T01:40:09 < mawk> yes
2020-02-18T01:40:13 < mawk>  /dev/stderr
2020-02-18T01:40:27 < karlp> don't have it.
2020-02-18T01:40:29 < mawk> and in general you can do /proc/self/fd/$FILENO for any file descriptor
2020-02-18T01:40:45 < mawk> the number is 2 for stderr
2020-02-18T01:40:56 < karlp> proc/self/fd looks great
2020-02-18T01:40:59  * karlp tries that
2020-02-18T01:41:19 < karlp> /dev/stderr are only symlinks on my desktop anyway
2020-02-18T01:41:33 < mawk> so /proc/self/fd/2 redirects to stderr, and 0 for stdin, 1 for stdout
2020-02-18T01:41:34 < mawk> yes
2020-02-18T01:45:08 < karlp> cute, json, plain text, and all the security of modern javascript https://privatebin.net/?72f27672c085b117#CnW2ZaT14cUb3w7zzXv4qTDaNot8S7BFma3iTCsEMP3m

2020-02-18T01:46:25 < Ultrasauce> highly recommend backtick strings any time you feel like using + for catentation
2020-02-18T01:46:57 < doomba> cool. what website is this on?
2020-02-18T01:47:45 < doomba> cuz they gonna get defaced by pakistanis if any of those vars are user supplied
2020-02-18T01:48:28 < karlp> Ultrasauce: you bet.  if they're on this page, they can just use fs.exec themselves though, so don't really feel like I'm opening anything up....
2020-02-18T01:48:37 < Ultrasauce> i mean style wise
2020-02-18T01:48:50 < karlp> oh, you mean template string stuff?
2020-02-18T01:48:51 < Ultrasauce> yes
2020-02-18T01:48:52 < karlp> that'
2020-02-18T01:48:54 < karlp> s es6 though...

2020-02-18T19:03:27 < Cracki> what's an inverted breakout supposed to do?
2020-02-18T19:03:36 < Cracki> breakin?
2020-02-18T19:04:08 < Cracki> i see zif sockets that claim to be tssop48
2020-02-18T19:04:13 < Cracki> *take
2020-02-18T19:05:57 < kakimir> https://guide.alibaba.com/shop/proto-advantage-tsop-48-i-to-dip-48-smt-adapter-0-5-mm-pitch-16-22-mm-body_1016017607.html I want this but like... inverted
2020-02-18T19:06:47 < kakimir> tsop48 changed from "female" to "male"
2020-02-18T19:06:49 < Cracki> so... something that takes 0.1" dip or something, and can contact on top of a tssop48 footprint
2020-02-18T19:06:57 < Cracki> hmmm
2020-02-18T19:06:58 < Steffanx> So solder it up side down? 
2020-02-18T19:07:11 < Steffanx> In your oven
2020-02-18T19:07:11 < Cracki> what pitch is that, perhaps you can abuse flatflex for that
2020-02-18T19:07:44 < kakimir> 0.5
2020-02-18T19:07:57 < Cracki> not sure if there's anything readymade for this. if I needed this, I'd try bodging up some existing flatflexes, or have a flatflex or two made that fit
2020-02-18T19:08:19 < Cracki> perhaps you could do this with pogopins, staggered if the tssop48 pads are long enough for staggering
2020-02-18T19:08:32 < Cracki> not sure how permanent it needs to be
2020-02-18T19:09:04 < Cracki> or take enameled magnet wire and contact each pad manually
2020-02-18T19:09:39 < Cracki> or... lobotomize some tssop48 chip, then solder that on the board, then take a tssop48 clamp to contact the brainless legs
2020-02-18T19:10:05 < kakimir> these are not efficient solutions
2020-02-18T19:11:09 < Cracki> well, the most efficient I can imagine is taking 0.5mm flatflex, solder one end on each row of pads, and take the other ends of both cables and stick them into proper sockets on some breakout board that runs traces from those sockets to whatever header you need
2020-02-18T19:11:48 < Cracki> soldering flatflex to board seems to involve a wide spatula like soldering tip
2020-02-18T19:14:05 < kakimir> there is only one tip I need
2020-02-18T19:14:22 < kakimir> ts-bc2
2020-02-18T19:14:26 < kakimir> does everything
2020-02-18T19:14:41 < mawk> I already did it with a regular tip

2020-02-18T19:16:08 < mawk> je suis aussi grand que dieu, et dieu est aussi petit que moi
2020-02-18T19:26:49 < kakimir> let's see if I have flatflex in my garbages
2020-02-18T19:27:58 < Cracki> hm right, if you have a normal breakout too, solder the other end to that without a socket
2020-02-18T19:28:38 < Cracki> maybe you can skip the flatflex entirely... but that would mean you have to put the breakout on top of the actual board and solder those pads together like a QFN or BGA
2020-02-18T19:28:52 < Cracki> and then nothing can be around it either
2020-02-18T19:29:53 < kakimir> I don't have shit
2020-02-18T19:30:23 < Cracki> hm, buy shit or get going with enamel wire :>

2020-02-18T19:52:19 < Cracki> why would you need anything to remove enamel, just let the solder melt it away
2020-02-18T19:52:57 < Cracki> there's enamel hardly melts, that's for actually winding stuff :> there's wire explicitly for soldering, that works like a charm
2020-02-18T19:53:28 < mawk> should I mesure 0V between any pair of pad on a smartphone battery ?
2020-02-18T19:53:41 < mawk> like, I don't know, the BMS is too smart

2020-02-18T19:55:11 < Cracki> the bat for my old nexus 4 has four traces on its short flatflex. two are for power. they measure exactly the cell voltage you'd expect
2020-02-18T19:55:47 < kakimir73> if you can melt it with normal soldering temperatures
2020-02-18T19:55:50 < kakimir73> it's not enamel
2020-02-18T19:56:03 < Cracki> there is likely logic in that battery but it can't rely on some 'enable' signal from the rest of the phone because *there* is no power
2020-02-18T19:56:31 < kakimir73> if you go higher then copper oxidizes or some shit happens that makes solder not to like it

2020-02-18T20:31:05 < kakimir> Plated half holes are available in both standard PCB and advanced PCB. For standard PCB service, the minimum diameter of castellated holes is 0.6 mm. If you need smaller castellated holes  please ask our sale to offer advanced PCB service.  And the minimum distance between two Plated half holes is 0.55 mm.

2020-02-18T20:35:18 < Cracki> I tell you, just lobotomize a sacrificial chip
2020-02-18T20:35:38 < Cracki> castellated holes at 0.5mm pitch is like cut open vias
2020-02-18T20:36:52 < Cracki> perhaps run traces "off the board" with a sharp cut, then stand that upside on your board and solder at 90 degree angle
2020-02-18T20:37:09 < zyp> or just do pads on bottom
2020-02-18T20:37:17 < Cracki> I'm not sure they can do straight strips on the edge of a board down across

2020-02-18T20:37:48 < Cracki> he has to run traces out of all that though. it's only getting more crowded inside the tssop48 outline
2020-02-18T20:37:54 < kakimir> pads will do
2020-02-18T20:37:59 < zyp> castellated holes have the advantage you can solder with a normal iron, pads on bottom is essentially a LGA that you'd have to reflow

2020-02-18T20:39:01 < Cracki> I don't see a real advantage to soldering flatflex cables to the footprint

2020-02-18T22:07:28 < zyp> so if I wanna hook up a bunch of memory to a fpga, can't I just slap down a so-dimm socket?
2020-02-18T22:08:04 < qyx> is it that easy?
2020-02-18T22:08:26 < zyp> I guess the main reason not to do it is because then you have to deal with a 64/72-bit wide data bus to access all the memory
2020-02-18T22:08:48 < Ultrasauce> i kinda want to write a dram controller but also kinda dont
2020-02-18T22:09:11 < zyp> fpga devboards tends to use a pair of 16-bit chips, it seems
2020-02-18T22:10:06 < qyx> I would hardwire it to 64bit
2020-02-18T22:10:28 < qyx> does it matter if your bunch is 4G or 5G
2020-02-18T22:10:45 < zyp> Ultrasauce, I don't want to write one, I'm happy to instance an already working core written by somebody who knows what they are doing

2020-02-19T02:41:29 < englishman> aandrew: xilinx question
2020-02-19T02:41:51 < englishman> spartan 6 programmed by serial nor flash
2020-02-19T02:42:09 < englishman> the flash image was indrectly programmed through impact
2020-02-19T02:42:14 < specing> englishman: ##fpga...
2020-02-19T02:42:27 < englishman> i created another flash image using progmem or whatever commandline tool

2020-02-19T02:42:35 < englishman> the two are exactly the same except for 1 bit
2020-02-19T02:43:01 < englishman> the difference is, the impact one uses cclk as expected but the progmem created one uses tck
2020-02-19T02:43:07 < englishman> which of course doesnt work as theres no jtag
2020-02-19T02:43:16 < englishman> but why did the progmem one use tck at all?
2020-02-19T02:43:32 < zyp> some dumb setting you've overlooked?
2020-02-19T02:43:42 < aandrew> englishman: yeah some dumb setting I bet
2020-02-19T02:43:47 < englishman> i dont see ANY clock settings in progmem
2020-02-19T02:43:55 < aandrew> I had similar weirdness with altera's tools. you have to make sure there isn't some idiotic default
2020-02-19T02:44:44 < englishman> and it makes sense that progmem does not touch clocking at all
2020-02-19T02:44:52 < aandrew> I wonder if the progmem util assumes it's going to be done via JTAG
2020-02-19T02:45:01 < kakimir> thing is that if there is commands, addresses and data at 25Mhz
2020-02-19T02:45:07 < kakimir> and core is 48mhz
2020-02-19T02:45:14 < englishman> or if the mcs input file had it set there... and impact changed it due to the block diagram
2020-02-19T02:45:18 < aandrew> specing is right though, the xilinx experts in ##fpga would be a really good resource for this
2020-02-19T02:45:23 < zyp> englishman, clock source for what btw?
2020-02-19T02:45:35 < englishman> i lurked there for like a year and nothing interesting ever happened
2020-02-19T02:45:40 < englishman> zyp, configuration
2020-02-19T02:45:46 < kakimir> how to even capture which part is command, address and data
2020-02-19T02:47:31 < aandrew> kakimir: if you want to do nand emu you're likely gonna be doing it with an fpga with sram on the side
2020-02-19T02:47:43 < aandrew> and usb to load/modify sram as interesting things happen
2020-02-19T02:47:47 < englishman> also lol at the spartan 6 clock being +- 50% tolerant
2020-02-19T02:48:02 < aandrew> like you said, you gotta respond quickly and USB is fail for that
2020-02-19T02:48:03 < specing> couldn't an stm32 do nand emu?
2020-02-19T02:48:21 < aandrew> specing: I don't know if it can emulate a NAND chip itself, FMC is for driving a NAND chip
2020-02-19T02:48:29 < specing> with pseudo DRAM
2020-02-19T02:48:38 < specing> on qspi or soemthing
2020-02-19T02:48:43 < aandrew> and I'm not sure you're going to read GPIO, decode and drive GPIO fast enough
2020-02-19T02:48:46 < specing> pseudo SRAM*
2020-02-19T02:52:46 < kakimir> but if configuration 3 * 1024B(8bit wide IO) + 2 * 512B(spi capturing command latch) is used then maybe
2020-02-19T02:53:03 < kakimir> kinda dirty but maybe!

2020-02-19T03:17:38 < aandrew> I wonder if pro memory emulators ahve a clock interface
2020-02-19T03:17:47 < kakimir> system image that doesn't need even flashing
2020-02-19T03:17:49 < aandrew> i.e. when this location is accessed, stop the clock that's driving the cpu or someshit
2020-02-19T03:18:04 < aandrew> not sure how usefult hat is on second thought since everything has PLLs inside now
2020-02-19T03:18:55 < kakimir> does anything have an external halt input?

2020-02-19T03:19:46 < kakimir> Ultrasauce: how about when you work on bootloader?
2020-02-19T03:20:10 < Ultrasauce> then youre flashing a couple megs at most
2020-02-19T03:20:38 < kakimir> when device doesn't have exposed / any good interfaces for flashing in system?
2020-02-19T03:21:05 < kakimir> okay this is like niche thing I admit
2020-02-19T03:21:23 < Ultrasauce> if it has no jtag youre not going to have a good time writing a damn bootloader
2020-02-19T03:22:17 < zyp> instead of emulating a nand flash, just hook a nand programmer in between the board and the flash

2020-02-19T13:35:46 < karlp> another thing that absolutely doesn't benefit from being split into 50 hundred separate tweets
2020-02-19T13:35:53 < karlp> for fucks sake. 
2020-02-19T13:36:46 < englishman> good old twitter

2020-02-19T13:38:36 < dongs> you should get it while its on sale
2020-02-19T13:38:38 < zyp> except I want one with more ports
2020-02-19T13:38:42 < dongs> not gonna happen
2020-02-19T13:38:48 < dongs> trust me its the only thing that isnt shit
2020-02-19T13:38:51 < dongs> for this kinda spec
2020-02-19T13:38:57 < dongs> the ones with "more ports" are like 65W combined across all
2020-02-19T13:38:58 < zyp> true, I was looking all over a few weeks ago
2020-02-19T13:39:06 < dongs> or shitty chink stuff
2020-02-19T13:39:11 < englishman> is that the charger that can fly you to the moon
2020-02-19T13:39:15 < dongs> yeah
2020-02-19T13:39:19 < dongs> and back
2020-02-19T13:39:29 < zyp> the hyperjuice shit that was crowdfunded looks nice too
2020-02-19T13:39:35 < dongs> > dickstarter
2020-02-19T13:39:36 < zyp> still only four ports though
2020-02-19T13:39:44 < dongs> i'll wait until its on fucking amazon with next day shipping
2020-02-19T13:40:00 < dongs> all those recent GaN charger dickstarters are all coming from that PowerIntegrators one-chip thing
2020-02-19T13:40:08 < dongs> they just copypaste same design and slap a new name on it
2020-02-19T13:40:17 < englishman> dong is your xps13 usbc charging
2020-02-19T13:40:18 < dongs> that place better deliver the actual ICs
2020-02-19T13:40:24 < zyp> yeah, I'm not getting it from dickstarter either
2020-02-19T13:40:26 < dongs> yes of course it is
2020-02-19T13:40:30 < englishman> cool
2020-02-19T13:40:45 < englishman> why not get a macbook charger then
2020-02-19T13:40:47 < dongs> and i have a 45W PD anker which im replacin with this thing
2020-02-19T13:40:54 < dongs> because i want some -A ports for charging other shit
2020-02-19T13:40:55 < englishman> it comes with a cable
2020-02-19T13:40:58 < dongs> and im not a faggot
2020-02-19T13:41:46 < englishman> someone at work is expensing a $2500 xeon laptop to run altium
2020-02-19T13:42:16 < zyp> the problem with only four ports is that I want something that can charge everything I bring when I travel
2020-02-19T13:42:17 < dongs> wel;l
2020-02-19T13:42:24 < dongs> englishman: they do need something with the best single core perf
2020-02-19T13:42:29 < dongs> since altium is fucking unthreaded pascal garbage
2020-02-19T13:42:32 < englishman> but onboard gfx
2020-02-19T13:42:38 < dongs> thats kinda rip
2020-02-19T13:42:44 < zyp> and if I need to bring two devices anyway, I might as well bring a single port usb-c charger and one of the old 6-port usb-A ankers that I've already got
2020-02-19T13:42:47 < dongs> i got the new iris plus 1065G thing
2020-02-19T13:43:07 < dongs> zyp, you need more than 3 ports to cahrge other shit?
2020-02-19T13:43:21 < englishman> in what laptop
2020-02-19T13:43:22 < dongs> i'm ok wiht one PD going to laptop and like, one PD to phone (yay) and the other 2 -A for random shit
2020-02-19T13:43:23 < englishman> another xps13?

2020-02-19T13:49:39 < dongs> 1080piss is IPS, but 4K is oled only
2020-02-19T13:49:58 < dongs> unless tehy have a special racist canadian version
2020-02-19T13:50:08 < englishman> usually yes due to kb
2020-02-19T13:50:15 < englishman> which is why i get them from USA
2020-02-19T13:50:25 < englishman> so the keyboard is not all graffitid with a bunch of shit
2020-02-19T13:50:33 < dongs> haha
2020-02-19T13:59:34 < zyp> I hate it when assholes are too cheap to make a dedicated norwegian keyboard, so they grafitti it with labelling for swedish and danish too
2020-02-19T14:00:03 < karlp> at least you get a version with graffiti even as an option
2020-02-19T14:00:12 < karlp> think about poor me with icelandic layout
2020-02-19T14:00:36 < zyp> how does that work?
2020-02-19T14:00:37 < karlp> we get a set of 6 stickers to stick on _your_ scandi graffitied keyboard, out of the box from hp/ms
2020-02-19T14:00:42 < zyp> haha
2020-02-19T14:00:46 < PaulFertser> Don't you all touch-type?
2020-02-19T14:01:16 < BrainDamage>  even if you touch type you need some alignment indicators
2020-02-19T14:01:17 < zyp> PaulFertser, sure, but not having to look at it doesn't make it look any less ridiculous
2020-02-19T14:01:30 < BrainDamage> like where to place fingers, etc
2020-02-19T14:01:36 < karlp> sure, but it's still nice to hve sometimes, and I still have  aproblem sometimes with the characeters on the top right corner,  \ and -_ move around there between layouts
2020-02-19T14:02:06 < BrainDamage> also for rarely used keys like symbols, you don't usually touch type, at least I don't
2020-02-19T14:02:07 < karlp> I'm not this sort of lunatic: https://www.daskeyboard.com/daskeyboard-4-ultimate/
2020-02-19T14:02:23 < PaulFertser> BrainDamage: yes, but aren't they the same on all keyboards? Like two dots on the letters where you place the index fingers?
2020-02-19T14:02:37 < zyp> PaulFertser, yes, they are
2020-02-19T14:03:01 < zyp> BrainDamage, most symbols are not marked
2020-02-19T14:03:17 < BrainDamage> I have worn out the indentations on mine >.>
2020-02-19T14:03:25 < karlp> speaking of, we bought a new microwave recently, and it has a smooth touch panel thing (buttons behind flat membranes) and it has _no_ raised markers on it anywhere. so it's a fucking cunt to use in the dark.
2020-02-19T14:03:29 < PaulFertser> zyp: most keyboards in the world have "qwerty" layout. I guess looking at them should be offensive too for someone who doesn't like ridiculous ;)
2020-02-19T14:03:50 < karlp> PaulFertser: I have most problems with the edges around the qwerty, not the the main middle section
2020-02-19T14:04:03 < PaulFertser> karlp: cyanoacrylate drop should help with that
2020-02-19T14:04:25 < karlp> indeed, just mentioning it as a design failing
2020-02-19T14:04:29 < englishman> idk why microwaves have more than 1 button
2020-02-19T14:04:35 < PaulFertser> karlp: people are so dumb :(
2020-02-19T14:04:47 < BrainDamage> because you want to be able to chose power too, not just time
2020-02-19T14:05:07 < karlp> BrainDamage: spoken like someone who has a quality microwave, not a nuking device.
2020-02-19T14:05:11 < zyp> https://bin.jvnv.net/file/E6SG7.jpg <- I think this is the only keyboard I've got that's labelled for multiple languages
2020-02-19T14:05:20 < zyp> green is norwegian, red is danish, I believe
2020-02-19T14:05:23 < kakigate> I think nand emulator could be build a state machine around sram chip
2020-02-19T14:05:30 < zyp> and the white labels on those are swedish
2020-02-19T14:05:51 < BrainDamage> btw, I got a us keyboard because I got tired to have [] as 2nd level modifiers and {} as third level
2020-02-19T14:06:02 < BrainDamage> it made programming a finger chore
2020-02-19T14:06:28 < BrainDamage> even worse editing latex
2020-02-19T14:06:33 < kakigate> fx2lp being there in only purpose of moving pages from sram to pc and pc to sram
2020-02-19T14:07:10 < PaulFertser> karlp: but are you using qwerty for English?
2020-02-19T14:08:21 < karlp> icelandic takes the symbols outside qwerty and adds letters there,
2020-02-19T14:08:51 < karlp> BrainDamage: yar, icelandic layout is [] and {} both on third level, pretty horrific for development
2020-02-19T14:08:54 < PaulFertser> karlp: but I'm asking about you typing English texts
2020-02-19T14:09:07 < karlp> for typing english only, icealndic and us are identical.
2020-02-19T14:09:17 < PaulFertser> karlp: what's us, qwerty?
2020-02-19T14:09:18 < karlp> I could take all teh labels of the english a-z
2020-02-19T14:09:42 < karlp> qwerty to me is just the order of the first keys on the top row, it's not really a description of a layout :)
2020-02-19T14:10:20 < PaulFertser> karlp: but there's no non-ridiculous layout that order the first keys on the top row that way.
2020-02-19T14:11:07 < karlp> you've lost me.
2020-02-19T14:11:27 < zyp> I don't find holding altgr to type {[]} to be any harder than holding shift to type capital letters
2020-02-19T14:11:44 < karlp> yeah, I've gotten used to it at least .
2020-02-19T14:12:44 < karlp> fuckin curl.  only way to turn off the progress bar is with -s.
2020-02-19T14:12:51 < PaulFertser> karlp: the layouts that have qwerty as the top row are all highly suboptimal for typing texts in English.
2020-02-19T14:12:53 < BrainDamage> zyp: in italian layout {} is altgr + shift ++ key
2020-02-19T14:13:03 < PaulFertser> karlp: one is supposed to be using Dvorak or Colemak.
2020-02-19T14:13:18 < karlp> PaulFertser: on your unicycle hipster
2020-02-19T14:13:27 < PaulFertser> karlp: btw, I can ride unicycle a bit.
2020-02-19T14:13:31  * karlp too :)
2020-02-19T14:13:44 < PaulFertser> karlp: Dvorak was developed early in the 20th century.
2020-02-19T14:13:44  * karlp even played unicycle handball

2020-02-19T14:19:00 < karlp> fucking curl.  use -o /tmp/someoutputfile I get a fucking progress bar.
2020-02-19T14:19:20 < karlp> don't use it, I get no progress bar, because it's a post, but I get mixed responses on output
2020-02-19T14:19:27 < srk> PaulFertser: oO cool! will test
2020-02-19T14:19:42 < srk> PaulFertser: does openocd support libgpiod as well? 
2020-02-19T14:19:51 < karlp> only way to turn it off is -s for silent, and that means taht if it fails to connect or times out I don't get any error message, just the code.
2020-02-19T14:20:05 < doomba> that's because curl is haxx              .se
2020-02-19T14:20:30 < PaulFertser> srk: nope
2020-02-19T14:21:01 < srk> hmm, let me see if I can add it
2020-02-19T14:21:10 < PaulFertser> srk: please feel free to offer better code there, I have too little Haskell experience to write something really beautiful.

2020-02-19T14:23:23 < srk> well do you actually need to wrap it in maybeT?
2020-02-19T14:23:31 < srk> since maybe has monad instance as well
2020-02-19T14:23:42 < srk> so does either
2020-02-19T14:24:04 < PaulFertser> srk: I need both IO and Maybe there... so monad transformers... so
2020-02-19T14:24:34 < srk> mm, right
2020-02-19T14:25:10 < srk> or you can do IO prior via mapM and just process that

2020-02-19T14:32:51 < financeDolphin> Hey guys, any idea how to disable WWDG interrupt on L4?
2020-02-19T14:33:20 < financeDolphin> tried the flash option bytes but without success
2020-02-19T14:33:44 < Cracki> how did you enable it
2020-02-19T14:33:59 < financeDolphin> I didn't enable it on purpose
2020-02-19T14:34:12 < financeDolphin> I use the L4 HAL from ST
2020-02-19T14:34:18 < Cracki> do you have the reference manual for your L4 in front of you
2020-02-19T14:34:19 < financeDolphin> only a HAL_Init() in main
2020-02-19T14:34:22 < financeDolphin> yep
2020-02-19T14:34:31 < Cracki> what does it say about wwdg
2020-02-19T14:34:32 < zyp> dongs, well, the one I've got only does 30W PD anyway, I bought it to charge my phone, not laptop
2020-02-19T14:34:53 < Cracki> l4 hal has docs too, even if they're hard to find. find them, see where they mention wwdg
2020-02-19T14:35:02 < dongs> your phone should be PD now right?
2020-02-19T14:35:07 < Cracki> did you generate your code with cubemx/cubeide
2020-02-19T14:35:24 < zyp> dongs, no, my new phone is using some other dumb shit
2020-02-19T14:35:46 < financeDolphin> Cracki, no, just downloaded it and used
2020-02-19T14:35:54 < financeDolphin> it worked fine for me for other devices
2020-02-19T14:36:19 < Cracki> why do you think the wwdg is active?
2020-02-19T14:36:34 < Thorn> maybe there is some unhandled interrupt/fault and the debugger incorrectly reports the current stack frame being in WWDG_IRQHandler which is aliased to every other default handler?
2020-02-19T14:36:37 < dongs> zyp, rip
2020-02-19T14:36:42 < Thorn> that happens often
2020-02-19T14:36:44 < zyp> if I understand it correctly, it's using some proprietary shit that regulates battery voltage on the charger side instead of in the phone
2020-02-19T14:36:45 < dongs> huawei has some custom shit but they also support legit PD
2020-02-19T14:36:59 < zyp> at 6A or some shit
2020-02-19T14:37:07 < financeDolphin> Cracki, I see the WWDG interrupt handler in gdb
2020-02-19T14:37:16 < dongs> huawei own custom thing is like 5V@4A
2020-02-19T14:37:26 < dongs> but they support PD up to 12V/??A
2020-02-19T14:37:29 < Thorn> financeDolphin: see my last msg
2020-02-19T14:37:31 < zyp> https://www.oneplus.com/no/7t/warp-charge
2020-02-19T14:37:44 < zyp> doesn't really matter
2020-02-19T14:38:05 < Cracki> well try calling the api to deinit wwdg https://os.mbed.com/users/EricLew/code/STM32L4xx_HAL_Driver/diff/7aef7655b0a8/Src/stm32l4xx_hal_wwdg.c/
2020-02-19T14:38:29 < Cracki> I'd also check what Thorn said
2020-02-19T14:38:40 < zyp> phone battery lasts all day anyway, so I just charge it overnight
2020-02-19T14:38:49 < zyp> so power doesn't really matter
2020-02-19T14:39:05 < financeDolphin> Okay, WWDG_SW is _not_ reset which would enable it via hardware
2020-02-19T14:39:24 < financeDolphin> No checking if HAL enables it somehow
2020-02-19T14:39:26 < Cracki> if you wrote all your code yourself (apart from the HAL), you probably did NOT write a wwdg irq handler... so gdb saying it's in there sounds wrong
2020-02-19T14:39:43 < zyp> WWDG is IRQ0
2020-02-19T14:39:45 < financeDolphin> Cracki, Thorn: I use the startup from ST
2020-02-19T14:39:54 < financeDolphin> They define all interrupt handlers
2020-02-19T14:40:36 < zyp> which means that when you have a common handler that all unused interrupts are aliased to, you're at an address with a bunch of labels, and WWDG is the one that got defined first
2020-02-19T14:40:54 < financeDolphin> Strange, OpenOCD says HardFault
2020-02-19T14:41:05 < Thorn> eureka
2020-02-19T14:41:05 < zyp> yes, hardfault is aliased to the same handler
2020-02-19T14:41:42 < financeDolphin> Okay, I try the fault debug script for gdb
2020-02-19T14:43:43 < financeDolphin> imprecise busfault oO
2020-02-19T14:43:45 < Thorn> btw l476rc is again $4.7 qty 10 in lcsc :/ the price drop must have been a mistake
2020-02-19T14:44:00 < Cracki> congrats, I love imprecise busfaults
2020-02-19T14:44:37 < Cracki> and I can't remember what I had to do to fix the one time I had one
2020-02-19T14:47:03 < dongs> what was it before?
2020-02-19T14:47:10 < financeDolphin> not even an address where it happend :-/
2020-02-19T14:49:05 < Thorn> financeDolphin: 1. are you using the correct linker script / cube config for your particular mcu? 2. remove as much code as you can (start with main() {while(true) {} }), verify the fault is gone, then add code back piece by piece
2020-02-19T14:50:06 < financeDolphin> Thorn, yeah, I'm checking the linker script right now because there is no script for the l422 in the HAL package
2020-02-19T14:50:20 < financeDolphin> I'm using the one for the 432
2020-02-19T14:50:20 < Thorn> cube generates one
2020-02-19T14:51:47 < Cracki> if it's not exactly the same, ram addresses may be wrong too
2020-02-19T14:52:04 < financeDolphin> Damn!
2020-02-19T14:52:08 < financeDolphin> estack!
2020-02-19T14:52:10 < Cracki> I think that was at least mentioned when I looked for causes for my problem
2020-02-19T14:52:21 < financeDolphin> fixed all addresses but missed that one
2020-02-19T14:52:27 < Cracki> great
2020-02-19T14:52:28 < financeDolphin> thanks guys!
2020-02-19T14:52:58 < Thorn> why are you editing linker scripts by hand as a beginner
2020-02-19T14:53:37 < Cracki> crystal ball says someone at work made him
2020-02-19T14:53:38 < financeDolphin> Thorn, I wouldn't say I'm a beginner ;)

2020-02-19T15:19:29 < dongs> anyway i just emailed them and got this step in like 10 mins
2020-02-19T15:19:33 < dongs> like last year sometime
2020-02-19T15:19:43 < dongs> i was like "hi i am using your shit in production plz give 3d"
2020-02-19T15:21:40 < invzim> it was the plz that did it!
2020-02-19T15:22:48 < karlp> we can put that in zpsnips directly if we like? are they going to get grumpy about it? we can remov it ifthey complain...
2020-02-19T15:24:39 < dongs> idk how long that link will last
2020-02-19T15:24:46 < dongs> maybe you can re-host it on bin.jvnv or whatever
2020-02-19T15:24:49 < dongs> zyps' paste site
2020-02-19T15:25:00 < dongs> i just googled free uploader and clicked 1st link
2020-02-19T15:29:22 < karlp> well, we can put binaries in git, I don't mind, if no-ones upset about st33lin theyz filez

2020-02-19T15:34:01 < dongs> its like 30k zipped
2020-02-19T15:38:15 < invzim> is usb shield well defined for usb-c?
2020-02-19T15:38:30 < invzim> i.e. to gnd, via caps etc etc
2020-02-19T15:38:52 < invzim> for usb2 pretty much everyone had their own take on it
2020-02-19T15:44:16 < karlp> I don't imagine anything's changed there, if anything it's worse
2020-02-19T15:44:30 < karlp> usb2 had different advice for host/device ends, which people often mixed up.
2020-02-19T15:47:33 < zyp> I've never cared and just hook it to ground
2020-02-19T15:48:55 < Thorn> I've been told multiple times to connect shield to gnd  vla 1MΩ with a cap in parallel
2020-02-19T15:49:19 < Thorn> not sure where the truth is
2020-02-19T15:49:35 < karlp> Thorn: if you get theapp notes from different vendors like cyrpress/microchip/ti you'll get different recommendations :)
2020-02-19T15:50:02 < BrainDamage> ground on one side is fine, ground on both side if they also tie to PE you'll get a ground loop
2020-02-19T15:50:08 < BrainDamage> and some extra noise induced
2020-02-19T15:50:20 < doomba> ya i don't get why datasheet applications information always have a bunch of extra bullshit passives in the schematics - or it's the opposite... no passives.
2020-02-19T15:50:33 < doomba> like they expect you to have an EE degree to understand it... such retarded.
2020-02-19T15:50:36 < zyp> let's see, I've got the usb-c spec open already so let's see what it says
2020-02-19T15:51:13 < BrainDamage> doomba: there was a h bridge psu schematic that had a seemingly senseless cap on the output ... so I omitted it
2020-02-19T15:51:30 < BrainDamage> the transformer arced over and I suddenly understood why
2020-02-19T15:51:38 < invzim> Put this as a note in a schematic:
2020-02-19T15:51:41 < invzim> Intel: Connect shield to GND

2020-02-19T16:04:34 < Thorn> so no passives in between?
2020-02-19T16:05:41 < zyp> it's not really very explicit on that
2020-02-19T16:05:47 < zyp> but sounds not
2020-02-19T16:13:57 < karlp> what do they mean by apertures as small as possible? I mean, what's the use case for making apertures/holes bigger? there's really only one size they can be, the size of the part? or are they saying, "don't make the shield tab in the footprint 6mm square"?
2020-02-19T16:14:46 < zyp> I think they are talking about openings between the pcb and the shield
2020-02-19T16:15:03 < karlp> meaning?
2020-02-19T16:15:33 < zyp> «Apertures in the receptacle and plug shells should be minimized. If apertures are unavoidable, a maximum aperture size of 1.5 mm is recommended. See Figure 3-69 for aperture illustrations. Copper tape may be applied to seal the apertures inside

2020-02-19T17:01:08 < dongs> they wont ask for eus
2020-02-19T17:01:21 < qyx> they wont deliver.
2020-02-19T17:01:27 < dongs> why not?
2020-02-19T17:01:30 < dongs> i thought they're back to work
2020-02-19T17:01:34 < qyx> are they back?
2020-02-19T17:01:37 < dongs> seems so
2020-02-19T17:01:39 < dongs> according to their site
2020-02-19T17:01:48 < qyx> or was it seed extending to Feb 17

2020-02-19T17:02:28 < qyx> COVID-2019 is arriving
2020-02-19T17:03:16 < qyx> so those were plain lies, they did not send the thing on Feb 4.
2020-02-19T17:03:38 < qyx> but on Feb 12 instead
2020-02-19T17:04:51 < qyx> Production of 4&6 layer and ENIG PCBs will temporarily be postponed until further notice
2020-02-19T17:04:54 < qyx> heh
2020-02-19T17:05:08 < qyx> so they are still doing 2L only
2020-02-19T17:07:07 < Cracki> it's their secret eugenics project. cull the frail ones.
2020-02-19T17:07:51 < Cracki> seems I got one order returned to china too, right when it entered my country. the first in years.
2020-02-19T17:11:07 < englishman> does lcsc do preprogramming
2020-02-19T17:13:18 < dongs> of course not
2020-02-19T17:13:20 < dongs> are you kidding
2020-02-19T17:13:49 < karlp> doesn't digikey offer that? or do they hate kanadias too?
2020-02-19T17:14:06 < englishman> digijews are in usa
2020-02-19T17:14:16 < englishman> same shit.

2020-02-19T17:21:54 < doomba> jlcpcb just shipped my rube goldberg powered j-link adapter pcbs
2020-02-19T17:21:57 < doomba> coronavirus be damned!
2020-02-19T17:23:25 < invzim> doomba: shipping label created, or actually shipped?
2020-02-19T17:23:43 < qyx> I had 8 days between the two
2020-02-19T17:24:40 < doomba> invzim: i'm not sure how to tell the difference on 17track. didn't look but assuming it says "sent to air transport" which probably really means label created?
2020-02-19T17:24:52 < dongs> > using 17track
2020-02-19T17:24:53 < dongs> what teh fck
2020-02-19T17:24:59 < dongs> what nigger courier are you using that doesnt have proper tracking?
2020-02-19T17:25:00 < doomba> 17track is da besssssss
2020-02-19T17:25:01 < invzim> no ida, only dhl for me

2020-02-19T17:25:39 < dongs> retarded shit
2020-02-19T17:25:48 < doomba> nah cheap shit for poor people
2020-02-19T17:25:49 < dongs> why are ytou so brokebitch
2020-02-19T17:25:51 < dongs> yes exactly
2020-02-19T17:25:58 < dongs> even invzim can afford DHL
2020-02-19T17:26:00 < doomba> why pay $19 to fucking DHL for $2 pcb? that's what i call retarded
2020-02-19T17:26:04 < dongs> and hes in fucking romania or someshit
2020-02-19T17:26:10 < dongs> thats cuz PCB isnt really $2
2020-02-19T17:26:14 < dongs> its $21
2020-02-19T17:26:16 < dongs> and shipping is free
2020-02-19T17:26:30 < qyx> the problem with dhl is that all dhl parcels above 20€ are going thru customs
2020-02-19T17:26:34 < doomba> i just paid $7.24 for 5 pcbs tho
2020-02-19T17:26:38 < doomba> that's a pretty good deal
2020-02-19T17:26:42 < qyx> for epacket/slow post the limit is 120€ here
2020-02-19T17:26:45 < doomba> $2 + $5.24 shipping
2020-02-19T17:27:05 < doomba> plus it adds extra delay so coronavirus dies in transit

2020-02-19T21:25:38 < antto> Q: wut dis look liek to u?
2020-02-19T21:26:02 < Steffanx> A programmer 
2020-02-19T21:26:04 < antto> A) an stlink2 clone
2020-02-19T21:26:15 < antto> B) a serial-over-USB module
2020-02-19T21:26:23 < antto> C) fish
2020-02-19T21:26:34 < Steffanx> D) 42
2020-02-19T21:27:07 < Steffanx> It wont program your eggs, antto  
2020-02-19T21:27:27 < Steffanx> The eggsmega
2020-02-19T21:27:36 < antto> i know that
2020-02-19T21:27:44 < Steffanx> Ok
2020-02-19T21:27:55 < Steffanx> What else you know?
2020-02-19T21:28:49 < antto> i honestly want to know the answer to the above question ^
2020-02-19T21:30:05 < antto> don't just merely look at what the URL says
2020-02-19T21:30:47 < Steffanx> Hasn't that thing been around for ages?
2020-02-19T21:31:10 < antto> okay, so you too, like me, think the answer is A
2020-02-19T21:31:19 < Steffanx> I do recall it had some issue with the reset line. But I might be wrong
2020-02-19T21:31:30 < Steffanx> I think someone like PaulFertser  might know
2020-02-19T21:31:38 < antto> but what i akchually got when i bought it is.. a serial-over-USB
2020-02-19T21:31:46 < Steffanx> Hm
2020-02-19T21:32:06 < antto> 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter
2020-02-19T21:32:30 < Cracki> so they sent you a similar looking thing?
2020-02-19T21:32:43 < antto> it's exactly as on the picture there
2020-02-19T21:32:44 < Cracki> those metal cases are ubiquitous
2020-02-19T21:32:48 < antto> including the pinout
2020-02-19T21:32:52 < Cracki> wat
2020-02-19T21:32:59 < Cracki> so the pinout is a lie?
2020-02-19T21:33:11 < antto> there are two chips in it, some SOIC8 and some SOIC16-ish
2020-02-19T21:33:25 < antto> no, the pinout is correct
2020-02-19T21:33:31 < Cracki> oh, item title is wrong, item pictures = what was sent
2020-02-19T21:33:36 < antto> i get 3.3V on the TX and about 5-ish on the RX pin
2020-02-19T21:33:52 < Cracki> meh they ought to fix the item description
2020-02-19T21:34:25 < antto> i think it is pretty much not usable as a programmer for SWD
2020-02-19T21:34:39 < antto> (but i'm not an expert)
2020-02-19T21:34:41 < Cracki> at most you can talk to the uart rom bl
2020-02-19T21:34:50 < antto> there's no bootloader
2020-02-19T21:35:00 < antto> i need SWD
2020-02-19T21:35:07 < Cracki> unless there's an f103 or something similar in there, it won't be able to host stlink firmware
2020-02-19T21:35:26 < Cracki> stm32 tend to have ROM bootloaders
2020-02-19T21:35:41 < antto> my chip is a SAME54
2020-02-19T21:35:45 < antto> no bootloader in it
2020-02-19T21:36:02 < Cracki> order one that says st-link v2 on the metal case? or something that's a jlink clone even?
2020-02-19T21:36:11 < antto> as for this "stlink2" i doubt there would be an arm cortex in it
2020-02-19T21:36:25 < antto> i know there are some arm cortexes in SOIC8 and SOIC16 packages but..
2020-02-19T21:36:53 < antto> nah, f*ck that, i waited 1 month for this sh*t
2020-02-19T21:37:15 < Steffanx> Awh
2020-02-19T21:37:16 < antto> this was the one with fastest shipping i could find
2020-02-19T21:37:34 < Cracki> any discos/nucleos around?
2020-02-19T21:37:37 < antto> no
2020-02-19T21:38:13 < antto> i contacted the seller a few minutes ago.. but i don't feel like sending this thing back to him (i'll have to pay the shipping)
2020-02-19T21:38:31 < Steffanx> It's unlikely you have to do that
2020-02-19T21:38:43 < antto> i wanna know if he honestly made a mistake or what
2020-02-19T21:39:08 < Steffanx> Probably just a refund
2020-02-19T21:39:29 < Cracki> it claims to have a "tck", so maybe the rxd/txd lines can be convinced to do SWD
2020-02-19T21:39:34 < Steffanx> Or negative feedback it is. They hate that
2020-02-19T21:39:35 < Cracki> can you identify those chips
2020-02-19T21:39:58 < antto> they look pitch black, lemme see thru the camera
2020-02-19T21:40:22 < Steffanx> Googled for similar devices/internals?
2020-02-19T21:40:35 < Steffanx> You can't be the first
2020-02-19T21:40:38 < antto> can't find the internals of it on a picture
2020-02-19T21:40:44 < Steffanx> Hm
2020-02-19T21:40:51 < Cracki> smells like they messed up pictures/product and textual description
2020-02-19T21:41:07 < antto> but there are many which look the same.. they say AUTO PROGRAMMER and USB-TTL and have the same pinout legend
2020-02-19T21:41:12 < antto> the logo varies
2020-02-19T21:41:30 < Cracki> if it ships fast, it may not be a chinese but some useless european/local seller
2020-02-19T21:42:38 < PaulFertser> Cracki: my guess is that it's just ch-340 inside, and TCK is meant for SPI flash programming.
2020-02-19T21:42:57 < Cracki> plausible

2020-02-19T21:45:42 < antto> on both chips the labels are either erased or never had any
2020-02-19T21:46:15 < Cracki> great. maybe the seller can explain (or not) how that thing is supposed to do SWD and SWIM
2020-02-19T21:46:37 < antto> a wat
2020-02-19T21:47:23 < antto> there's also a 12MHz crystal in there, big one
2020-02-19T21:47:29 < antto> HC49
2020-02-19T21:48:41 < antto> well, this is what lsusb says: "QinHeng Electronics HL-340 USB-Serial adapter"
2020-02-19T21:49:25 < Cracki> kek
2020-02-19T21:50:35 < Cracki> I would order a jlink (or clone) anyway. you'll love their Ozone program
2020-02-19T21:51:15 < antto> i need this to have SWD and work with debian and openocd
2020-02-19T21:51:25 < antto> and SAME54 or whatever
2020-02-19T21:51:46 < antto> jlink would have muchos shipping time again
2020-02-19T21:51:52 < Cracki> jlinks do swd too, and I think openocd can talk to them. they have a gdb server for certain.
2020-02-19T21:52:09 < antto> i mean
2020-02-19T21:52:19 < Cracki> if that thing you got isn't gonna do it, you'll have shipping time anyway
2020-02-19T21:52:33 < mawk> did you like my html fork bomb
2020-02-19T21:52:34 < antto> the situation is like this: i got a board with an arm cortex since january 7 or so
2020-02-19T21:52:41 < Cracki> how does html fork
2020-02-19T21:52:42 < mawk> https://xolus.net/
2020-02-19T21:52:48 < Cracki> not clicking that tyvm
2020-02-19T21:52:51 < mawk> by calling the same document in itself
2020-02-19T21:52:53 < mawk> lol
2020-02-19T21:52:55 < antto> and now i got two "programmers" and neither of them works with my chip
2020-02-19T21:52:59 < mawk> it doesn't crash the browser it's just cool to watch
2020-02-19T21:53:03 < Cracki> wats the other programmer
2020-02-19T21:53:11 < antto> turns out this "stlink2clone" isn't even a programmer
2020-02-19T21:53:20 < antto> so i will be buying a programmer for the third time
2020-02-19T21:53:26 < mawk> what do you mean not even a programmer
2020-02-19T21:53:41 < mawk> my manager agreed to give me embedded stuff
2020-02-19T21:53:43 < mawk> I will work on radar
2020-02-19T21:53:46 < Cracki> well a stlinkv2 (even clone) is swd and works with stm32, _maybe_ not non-st (never tried it)
2020-02-19T21:54:09 < mawk> it works very well with non st
2020-02-19T21:54:13 < mawk> with openocd
2020-02-19T21:54:16 < antto> Cracki, do you think this "QinHeng Electronics HL-340 USB-Serial adapter" will program your STM32 via SWD?
2020-02-19T21:54:23 < mawk> everything cortex M works
2020-02-19T21:54:26 < mawk> with SWD
2020-02-19T21:54:37 < Cracki> you'd have to find a datasheet for this hl-340 thing
2020-02-19T21:54:45 < Cracki> ftdi chips can do gpio
2020-02-19T21:54:52 < mawk> sounds like old style stlink
2020-02-19T21:55:00 < mawk> the serial thing
2020-02-19T21:55:25 < Cracki> I'm not familiar enough with swd electrically... gpio "blaster" might be good enough for swd
2020-02-19T21:55:26 < antto> then i have no idea how to wire it up to my arm cortex
2020-02-19T21:56:01 < Cracki> google it, maybe openocd knows it already
2020-02-19T21:56:48 < antto> do you think KEIL would support this kind of "programmer" ?
2020-02-19T21:56:59 -!- con3 [~con3@165.255.54.134] has joined ##stm32
2020-02-19T21:57:01 < Steffanx> ofcourse not.
2020-02-19T21:57:04 < antto> cuz the ebay listing mentions KEIL and what not
2020-02-19T21:57:06 < Steffanx> they only support $$$ tools
2020-02-19T21:57:20 < antto> anyway
2020-02-19T21:57:47 < Steffanx> it doesnt even crash my browser. how useless, mawk
2020-02-19T21:58:22 < mawk> gpio blaster works with swd yes Cracki 
2020-02-19T21:58:25 < mawk> even parallel port of your pc
2020-02-19T21:58:27 < mawk> eg printer port
2020-02-19T21:58:32 < mawk> openocd does all of this
2020-02-19T21:58:35 < antto> my point is.. i lost like almost two months with this sh*t, so now i need to buy a programmer for the third time, and it better be something that would abso-f*ckin-lutely work or FUUUU everything >:(
2020-02-19T21:58:40 < mawk> you should probably lower the speed tho
2020-02-19T21:58:48 < mawk> just buy a real stlink lol antto 
2020-02-19T21:58:52 < mawk> stop buying chinesies
2020-02-19T21:58:57 < mawk> buy french !
2020-02-19T21:58:59 < mawk> and italian
2020-02-19T21:59:07 < antto> this wos supposedly from UK
2020-02-19T21:59:12 < qyx> antto: buy jlink
2020-02-19T21:59:12 < antto> * woz
2020-02-19T21:59:20 < mawk> british are vile
2020-02-19T21:59:33 < antto> should i blame loirens? ;P~
2020-02-19T21:59:41 < Cracki> >from uk
2020-02-19T21:59:46 < Cracki> seller information is moon runes
2020-02-19T21:59:57 < Cracki> "from" uk may mean they have a warehouse there
2020-02-19T22:00:12 < Cracki> where everyone including the bugs and the rats speak chinese
2020-02-19T22:00:20 < antto> i waited 1 month for this to travel from UK to BG so it smells like china
2020-02-19T22:00:39 < qyx> at least it is covid-free
2020-02-19T22:00:56 < antto> boddax, mine is definately not like this
2020-02-19T22:01:16 < antto> there's a SOIC8 and a SOIC16
2020-02-19T22:01:22 < antto> and 12MHz crystal
2020-02-19T22:02:43 < antto> all of them have some QFP chip
2020-02-19T22:02:47 < antto> with much pins
2020-02-19T22:03:30 < antto> i'm thinking to buy this thing: https://wiki.kamamilabs.com/index.php/ZL33PRG
2020-02-19T22:03:53 < antto> i hate that the shipping is 33 euro b*t now i'm in rage
2020-02-19T22:04:16 < antto> i can't even type o_O
2020-02-19T22:04:43 < Cracki> 33 euro shipping?!
2020-02-19T22:04:49 < antto> yeah
2020-02-19T22:04:58 < antto> otherwise the programmer is 14euro
2020-02-19T22:05:00 < Cracki> for the thing you just got, or for a proper stlink or jlink?
2020-02-19T22:05:04 < Cracki> lol
2020-02-19T22:05:13 < Cracki> those stlink clones are less than 2 bucks on aliex from china
2020-02-19T22:05:27 < Cracki> why would you order this on ebay
2020-02-19T22:05:49 < antto> Cracki, i don't wanna wait another 1-to-3 months only to discover whether i get another serial-over-USB converter
2020-02-19T22:05:50 < qyx> also, if openocd supports g0
2020-02-19T22:06:08 < qyx> did you try any mpsse capable ftdi at hand?
2020-02-19T22:06:10 < Cracki> I picked some 2.50-eur-option and it took ~14 days to ship something from china
2020-02-19T22:06:28 < antto> this sh*t took a month from "UK"
2020-02-19T22:06:30 < Cracki> if you need it faster, they have that too... but not sure about .bg
2020-02-19T22:06:32 < qyx> if not, did you try rpi or any other single board computer? openocd supports gpio mode
2020-02-19T22:06:46 < qyx> if not, did you try bitbanging that serial adapter?
2020-02-19T22:06:58 < antto> haven't tried anything
2020-02-19T22:07:04 < antto> don't have any SBC
2020-02-19T22:07:49 < antto> i don't mind if the programmer only supports cortex M as long as it supports my chip
2020-02-19T22:08:39 < antto> ...but i don't wanna wait a pile of more time and then end up buying a programmer for the fourth time >:(
2020-02-19T22:09:11 < antto> so, i'm thinking to sacrifice 47 euro for that zl33prg
2020-02-19T22:09:18 < Cracki> then figure out if that hl-340 thing is like a ch340 thing, i.e. virtual com port
2020-02-19T22:09:20 < Cracki> it should be
2020-02-19T22:09:31 < Cracki> this (unrelated) indicates that the thing is a serial adapter https://www.patthoyts.tk/blog/
2020-02-19T22:09:51 < Cracki> wat is a zl33prg, sounds fishy
2020-02-19T22:10:04 < laurence_> https://www.bbc.co.uk/news/world-us-canada-51564215
2020-02-19T22:10:18 < antto> Cracki, https://wiki.kamamilabs.com/index.php/ZL33PRG
2020-02-19T22:10:24 < Cracki> play with what you have, a bunch of ppl have said now that a serial adapter can do SWD
2020-02-19T22:10:46 < PaulFertser> Cracki: not easily, afaict.
2020-02-19T22:11:01 < Cracki> srsly get a jlink v8 or something on aliex, pick shipping that promises an appropriate date, be done with it
2020-02-19T22:11:12 < PaulFertser> Nobody wrote an openocd driver for ch340 yet.
2020-02-19T22:11:19 < Cracki> kek
2020-02-19T22:11:33 < PaulFertser> But antto also has some ftdi part which is likely similar to ft232r, and that driver is available.
2020-02-19T22:11:43 < Cracki> oh he does? convenient
2020-02-19T22:11:53 < qyx> I did use ft232h with openocd
2020-02-19T22:11:56 < antto> wouldn't you need more than "TX" and "RX" for SWD?
2020-02-19T22:12:10 < Cracki> well, the clock, and ground, but that's it
2020-02-19T22:12:14 < qyx> you can bitbang using modem signals
2020-02-19T22:12:29 < antto> you mean those RTS CTS kind of sh*t?
2020-02-19T22:12:30 < PaulFertser> qyx: ft232h is proper fine device, supporting mpsse.
2020-02-19T22:12:45 < Cracki> very basic swd is just swdio, swclk, ground. swdio needs some resistor fuckery to be made to work from a txd+rdx
2020-02-19T22:12:48 < Cracki> *rxd
2020-02-19T22:12:48 < qyx> avrdude for example had support for bitbanging modem lines
2020-02-19T22:12:49 < PaulFertser> Cracki: swd needs a bidirectional pin
2020-02-19T22:12:49 -!- con3 [~con3@165.255.54.134] has quit [Quit: Leaving]
2020-02-19T22:12:57 < Cracki> or two unis
2020-02-19T22:13:14 < qyx> farnell also has 4€ shipping
2020-02-19T22:13:39 < qyx> if I may ask
2020-02-19T22:13:42 < qyx> whats the original problem?
2020-02-19T22:13:48 < antto> can a mere mortal like me add a 19euro thing to the cart and buy it from farnell?
2020-02-19T22:13:52 < qyx> the nucleo's stlink is not able to program g0?
2020-02-19T22:14:02 < antto> don't they have like a "ur too ghetto" tax?
2020-02-19T22:14:18 < antto> mouser does
2020-02-19T22:14:23 < antto> most do
2020-02-19T22:14:25 < PaulFertser> qyx: the original problem is that stlinkv3 can't handle non-st targets, it's not clear why yet
2020-02-19T22:14:28 < Cracki> he said he has some atmel SAM part
2020-02-19T22:14:42 < qyx> PaulFertser: and is he attempting to program a non-st target?
2020-02-19T22:14:47 < PaulFertser> qyx: yes
2020-02-19T22:14:51 < qyx> oh
2020-02-19T22:14:59 < Cracki> which is why I keep pushing jlink
2020-02-19T22:15:07 < qyx> cannot he downgrade it to stlink v2.1?
2020-02-19T22:15:15 < PaulFertser> qyx: different mcu
2020-02-19T22:15:16 < Cracki> not necessary but more convenient
2020-02-19T22:15:16 < qyx> I used that to program some sam part
2020-02-19T22:15:41 < Cracki> must be one of the very new nucleos to have a v3 on it
2020-02-19T22:15:52 < antto> the stlink3 i got is akchually "stlink3 mini"
2020-02-19T22:15:53 < qyx> I don't have any v3
2020-02-19T22:15:56 < antto> if it matters
2020-02-19T22:16:09 < Cracki> how do you have your SAME part? own board? or a devboard too?
2020-02-19T22:16:17 < PaulFertser> Can someone from EU just send antto a nucleo with 2-3 days shipping?
2020-02-19T22:16:45 < qyx> I can send him a stmF4discovery
2020-02-19T22:16:55 < antto> Cracki, https://i.imgur.com/9ggO8Dz.jpg
2020-02-19T22:17:17 < Cracki> nice
2020-02-19T22:17:18 < antto> i even designed the board with the stupid STDC14 connector as on the stlink3
2020-02-19T22:17:23 < antto> >:(
2020-02-19T22:17:32 < antto> which now is gonna get in the way
2020-02-19T22:17:45 < antto> not too much tho
2020-02-19T22:17:49 < Cracki> yeh, standard cortex m header would be a better idea for the future
2020-02-19T22:18:07 < antto> it was..
2020-02-19T22:18:21 < antto> untill near the end of the design stage where i eyeballed what programmer to get
2020-02-19T22:18:53 < antto> then i saw stlink3.. asked around.. someone said "lol, should wurk prolly, kekkek" and i said "gud"
2020-02-19T22:19:09 < antto> changed to STDC14
2020-02-19T22:19:23 < Cracki> learning eggsperience
2020-02-19T22:19:24 < qyx> you should have asked
2020-02-19T22:19:30 < Cracki> he did :>
2020-02-19T22:19:34 < Cracki> the wrong ppl answered
2020-02-19T22:19:44 < antto> no, how would they know
2020-02-19T22:19:55 < Cracki> or not enough to cast doubt on the opinions that were offered
2020-02-19T22:19:59 < PaulFertser> Do you remember who answered?
2020-02-19T22:20:10 < Cracki> there are logs you guys can grep
2020-02-19T22:20:20 < antto> i mean.. afaiu, ST has intentionally put some bug in the stlink3 implementation, to f*ck it up if you wanna use non-ST chips
2020-02-19T22:20:22 < Cracki> shall I start stacking up the fire wood?
2020-02-19T22:20:35 < antto> PaulFertser, doesn't matter, this must have happened in december
2020-02-19T22:20:39 < antto> last year
2020-02-19T22:20:39 < Cracki> hey!
2020-02-19T22:20:48 < Cracki> segger's jlink ob firmware MAY work on stlinkv3
2020-02-19T22:20:51 < Cracki> try that!
2020-02-19T22:20:56 < antto> plus, the stlink3mini wasn't uber eggspensive
2020-02-19T22:21:03 < antto> and i could, perhaps, sell it
2020-02-19T22:21:05 < Cracki> if that works, you may get it to work for non-st chips too
2020-02-19T22:21:25 < Cracki> you should check out right now if jlink ob firmware is available for stlinkv3
2020-02-19T22:21:36 < PaulFertser> is jlink ported to v3 already?
2020-02-19T22:21:49 < antto> how would i.. flash it onto it? ;P~
2020-02-19T22:21:56 < Cracki> they "ordered some boards" around august(?) 2019
2020-02-19T22:22:06 < Cracki> segger takes care of that
2020-02-19T22:22:15 < Cracki> they have their ways for stlinkv2, v2.1 too
2020-02-19T22:22:25 < Cracki> https://forum.segger.com/index.php/Thread/6397-SOLVED-STLink-conversion-utility-for-STLink-v3/
2020-02-19T22:22:42 < Cracki> dude says "planned" "in the next weeks"
2020-02-19T22:22:48 < Cracki> so it's been months, maybe they're done
2020-02-19T22:22:52 -!- bvernoux [~Ben@88.120.152.126] has joined ##stm32
2020-02-19T22:22:53 < Cracki> https://www.segger.com/products/debug-probes/j-link/models/j-link-ob/
2020-02-19T22:23:05 < antto> i see there are tons of options and my head hurts on so many levels
2020-02-19T22:23:13 < Cracki> without ordering new shit, this is the best option I see that may work or at least needs to be tried
2020-02-19T22:23:21 < antto> but i think so far i understood the DAPlink thing and it sounds promising to me
2020-02-19T22:23:43 < antto> i'll be "tied" to cortex-M only, but any chip from any vendor would work, including future ones
2020-02-19T22:23:46 < antto> right?
2020-02-19T22:24:06 < Cracki> that's the point of daplink
2020-02-19T22:24:21 < antto> so this tells me that it would definately work with my SAME54, which is cortex M4F
2020-02-19T22:24:32 < Cracki> could you check if the chip on your stlinkv3 mini is a SAM3U?
2020-02-19T22:24:35 < antto> and openocd has support for it
2020-02-19T22:24:45 < Cracki> if that's a sam3u, jlink ob may work on your stlinkv3
2020-02-19T22:25:00 < antto> Cracki, how can it be a SAM chip when stlink3 is from ST?!
2020-02-19T22:25:08 < antto> do they not have STM32 chips?
2020-02-19T22:25:10 < Cracki> hm good point
2020-02-19T22:25:23 < qyx> jlink ob works on some ST chips too
2020-02-19T22:25:23 < Cracki> they may or may not be using their own chips for the v3
2020-02-19T22:25:31 < antto> this stlink3mini i bought from mouser together with my BOM stuff
2020-02-19T22:25:37 < Cracki> it works on the f103 chips they use for stlinkv2.x
2020-02-19T22:25:49 < PaulFertser> Cracki: they're using st chips for v3 obviously
2020-02-19T22:26:04 < antto> i think it was some cortex M7 STM32 chip on it
2020-02-19T22:26:08 < antto> when i eyeballed it
2020-02-19T22:26:22 < Cracki> maybe make some noise in this thread https://forum.segger.com/index.php/Thread/6397-SOLVED-STLink-conversion-utility-for-STLink-v3/
2020-02-19T22:26:32 < Cracki> m7 rings a bell
2020-02-19T22:28:09 < antto> https://i0.wp.com/blog.st.com/wp-content/uploads/ST12443_STLINK_V3MINI_recto_new.jpg?ssl=1
2020-02-19T22:29:31 < Cracki> see if maybe their software can do it, even if that page above doesn't list it (yet) https://www.segger.com/products/debug-probes/j-link/models/other-j-links/st-link-on-board/
2020-02-19T22:29:47 < Cracki> that link lists some nucleos, is yours in there?
2020-02-19T22:30:00 < Cracki> (or any nucleo with v3 stlink on board)
2020-02-19T22:30:21 < PaulFertser> "The firmware is only to be used with ST target devices. Using it with other devices is prohibited and illegal." "The firmware is for use with evaluation boards only. It is not for use with custom hardware."
2020-02-19T22:30:43 < Cracki> didn't he have a nucleo
2020-02-19T22:31:03 < PaulFertser> Version history doesn't say anything about v3, so I guess they never got it supported.
2020-02-19T22:31:12 < Cracki> violating segger license isn't all that different from intending to buy a stlink clone (with st firmware on it)
2020-02-19T22:31:38 < antto> i don't have any arm cortexes besides the SAME54 on my board and the STM32 which is part of the stlink3mini
2020-02-19T22:31:51 < PaulFertser> The question is whom you respect more ;)
2020-02-19T22:32:01 < antto> in what way?
2020-02-19T22:32:25 < PaulFertser> Segger asks you to not use those "converted stlinks" for non-st targets and custom boards.
2020-02-19T22:32:54 < PaulFertser> Do you feel like their request should be honoured? More so than the ST's request to not produce clone stlinks?
2020-02-19T22:32:55 < antto> i learnt about segger: "skip them"
2020-02-19T22:32:56 < Cracki> good q :P I respect segger enough to buy their stuff when i start making more than cheap change from it
2020-02-19T22:33:17 < Cracki> segger: don't skip, use
2020-02-19T22:33:18 < antto> thus i was eyeballing something-DAPlink
2020-02-19T22:33:40 < Cracki> only reason to skip segger is price imho
2020-02-19T22:33:52 < antto> i mean, afaik segger is top-of-teh-icecream pro or something
2020-02-19T22:34:07 < antto> that's kewl and all, but i'm ghetto mortal
2020-02-19T22:34:17 < Cracki> unless that ftdi you have can be made to work, of that thing they sent you just now, sounds like you'll have to buy some more stuff
2020-02-19T22:34:36 < Cracki> well, a jlink clone off aliex is 10-20 bucks
2020-02-19T22:34:56 < antto> plus a month of waiting
2020-02-19T22:35:09 < Cracki> or half a month if you pay for more than the cheapest shipping
2020-02-19T22:35:25 < antto> got any example i can look at?
2020-02-19T22:35:31 < Cracki> not sure how awful they are about shipping to .bg but to .de is "tolerable"
2020-02-19T22:35:40 < antto> i've not used aliexpress before, only ebay
2020-02-19T22:35:58 < Cracki> aliex search for "jlink", you'll see arrays of black boxes with cables
2020-02-19T22:36:13 < Cracki> oh, that may be an issue then. I order off aliex with a credit card.
2020-02-19T22:36:35 < antto> i prefer paypal but..

2020-02-19T22:37:34 < Cracki> jlink v8 is what I have, I find it quite reliable. v9 exists too, seems to have new features.
2020-02-19T22:37:54 < Cracki> they don't have files to make the v10 hardware yet, at least not that I can see
2020-02-19T22:38:24 < Cracki> looks like ebay uk has those too
2020-02-19T22:38:37 < antto> yes, i saw many of those on ebay
2020-02-19T22:38:52 < antto> the descriptions looked scary and shipping time was horrific
2020-02-19T22:39:58 < antto> so i found one on alieggspress, 7-15 days shipping is like over 30 euros
2020-02-19T22:40:31 < antto> that is "aliexpress premium"
2020-02-19T22:40:54 < PaulFertser> antto: why do not you try that ftdi sync bitbanging?
2020-02-19T22:41:03 < antto> there are also other equally fast options from fedex/ups/dhl but they are much moar moniez than that
2020-02-19T22:41:06 < PaulFertser> What if it just works or almost works?
2020-02-19T22:41:57 < Cracki> ^
2020-02-19T22:41:57 < antto> PaulFertser, i honestly don't know wtf i'm doing already.. wasted so much time with selecting a cheap programmer
2020-02-19T22:42:02 < antto> not just my own time
2020-02-19T22:42:41 < antto> if it requires modifications then that means someone will probably have to help me with it coz i'm dumb
2020-02-19T22:42:56 < antto> and it might not even work at the end
2020-02-19T22:43:08 < antto> so DAPlink sounds more promissing
2020-02-19T22:43:40 < Cracki> use any ide? or command line and openocd?
2020-02-19T22:43:48 < antto> Code::Blocks
2020-02-19T22:43:51 < antto> on debian
2020-02-19T22:43:56 < Cracki> so openocd
2020-02-19T22:44:13 < antto> the initial plan was that the programmer would be usable via openocd, and openocd is usable via Code::Blocks
2020-02-19T22:44:42 < antto> on debian
2020-02-19T22:44:48 < PaulFertser> Yes, and OpenOCD has a ft232r driver.
2020-02-19T22:45:39 < antto> and also a DAP driver
2020-02-19T22:46:08 < antto> and many others, but DAP should work
2020-02-19T22:46:17 < antto> ftdi stuff i heard is "slow"
2020-02-19T22:46:39 < antto> and requires openocd to akchually know the target chip
2020-02-19T22:46:40 < PaulFertser> Not slower than shipping
2020-02-19T22:46:50 < PaulFertser> DAP stuff requires openocd to know the target chip too.
2020-02-19T22:46:57 < antto> hm
2020-02-19T22:46:58 < antto> true
2020-02-19T22:47:25 < antto> my thoughts are so messed up with this
2020-02-19T22:48:04 < antto> and a smol voice in my head tells me "buy that zl33prg or find a cheaper DAPlink"
2020-02-19T22:48:13 < qyx> ftdi is quite fast
2020-02-19T22:48:38 < PaulFertser> qyx: not ft232r
2020-02-19T22:48:56 < qyx> ro doesn't have mpsse?
2020-02-19T22:49:00 < qyx> s/ro/r
2020-02-19T22:49:05 < antto> oh, also, my cortex chip requires the reset to be used with SWD, i don't understand the details eggzactly
2020-02-19T22:49:06 < PaulFertser> qyx: y
2020-02-19T22:51:35 < antto> i found some DAPlinks on aliexpress too the other day
2020-02-19T22:51:50 < Steffanx> Whoa, 1 euro is almost getting 1 dollar. damn
2020-02-19T22:52:10 < antto> but shipping is either slow or eggspensive again
2020-02-19T22:52:28 < antto> so then zl33prg looks more legit
2020-02-19T22:52:41 < antto> ..to me
2020-02-19T22:53:54 < antto> afaik, the DAPlink firmware is under developement, and they've made a fancy bootloader that lets you update the programmer's DAP firmware.. using copy/paste..
2020-02-19T22:54:21 < antto> but on some of those "DAPlink" programmers on alieggspress, i didn't see them mention this and didn't see a button anywhere
2020-02-19T22:58:09 < antto> https://kamami.pl/en/stm32-programmers/575534-zl33prg-swd-programmer-debugger-for-arm-core-microcontrollers.html
2020-02-19T23:01:10 < Steffanx> isnt the stlinkv3 mini dirt cheap on farnell? Hows openocd support for that one?
2020-02-19T23:01:22 < PaulFertser> Steffanx: v3 is supported
2020-02-19T23:01:43 < PaulFertser> Steffanx: the problem is that the v3 firmware somehow doesn't work with non-st targets, not clear if that's an honest mistake or malice.
2020-02-19T23:01:51 < Steffanx> ah
2020-02-19T23:01:55 < Steffanx> bastards
2020-02-19T23:03:03 < srk> need to try flashing one v3 with blackmagic
2020-02-19T23:03:29 < PaulFertser> Does bmp support that MCU?
2020-02-19T23:03:32 < Steffanx> is the bmp still a thing?
2020-02-19T23:03:44 < laurence_> looks like jly flipped
2020-02-19T23:03:50 < srk> currently using it with blackmagic_hosted thingie which is probably same as what openocd does
2020-02-19T23:04:22 < laurence_> tfw I just used discovery
2020-02-19T23:04:35 < srk> PaulFertser: looks like it doesn't, there's f4/h7 targets
2020-02-19T23:04:52 < srk> and l4
2020-02-19T23:05:07 < srk> should work on f7..

2020-02-19T23:19:59 < antto> Steffanx, i *have* a stlink3mini
2020-02-19T23:20:09 < Steffanx> i see
2020-02-19T23:20:19 < antto> since january
2020-02-19T23:20:23 < antto> doesn't wurk
2020-02-19T23:20:38 < Steffanx> Yeah, what mr paul said. the bastards.
2020-02-19T23:21:08 < antto> PaulFertser, i'd say it's intentional, they would give you such uber cheap programmer only for their own chips
2020-02-19T23:21:14 < antto> it's perfectly logical
2020-02-19T23:21:33 < antto> not ARM-friendly IMO but logical as in biddness, i guess
2020-02-19T23:25:24 < Cracki> readout protection is active I take it?
2020-02-19T23:25:50 < Cracki> and fw updates encrypted?
2020-02-19T23:25:59 < antto> is that for me?
2020-02-19T23:26:05 < Cracki> anyone really
2020-02-19T23:26:32 < antto> i don't understand the question even
2020-02-19T23:26:44 < Cracki> I think the v2 firmware has been "opened up" so if there had been such a vendor lockin, one could patch that out
2020-02-19T23:27:08 < antto> v2 firmware like.. stlink v2?
2020-02-19T23:27:32 < Cracki> and whatever the segger people do must either be using official ST keys or those stlinks on nucleos/discos are maybe readout protected but not erase protected
2020-02-19T23:27:36 < Cracki> yes
2020-02-19T23:28:04 < antto> absolutely zero idea
2020-02-19T23:28:11 < antto> i'd think the hardware is different
2020-02-19T23:28:16 < antto> v2 vs v3
2020-02-19T23:28:23 < Cracki> I'm thinking this vendor lockin *itself* can't be too complicated, so let's hope all the protection around it is fail
2020-02-19T23:28:29 < Cracki> it certainly is
2020-02-19T23:28:29 < Steffanx> I can only imagine SEGGER talked with ST.
2020-02-19T23:28:43 < Steffanx> I dont see SEGGER do something like that without permission
2020-02-19T23:28:49 < Steffanx> they're way to serious for that
2020-02-19T23:28:49 < antto> "he STLINK-V3 is a complete architectural overhaul of its in-circuit debugger/programmer for STM8 and STM32 microcontrollers (MCU). The new technology can transfer data faster and with a lot more flexibility, thanks in part to its STDC-14 connector and its support of a virtual COM port."
2020-02-19T23:29:33 < Cracki> the 4 extra pins compared to cortex debug are for the VCP, iirc
2020-02-19T23:29:53 < Cracki> so I'm not sure the extra 4 pins make anything faster really. the CM7 makes things faster.
2020-02-19T23:30:17 < antto> i don't find this STDC14 thing spectacular, it's SWD in the middle, two unused pins on one side, two pins for a UART on the other side
2020-02-19T23:30:24 < Cracki> right
2020-02-19T23:30:41 < antto> but i think it was cortex M7 on this, not sure what the v2 has
2020-02-19T23:30:51 < Cracki> v2 is a f103, so M3
2020-02-19T23:31:34 < Cracki> also the M7 probably has strictly more than 12 Mbit/s USB
2020-02-19T23:32:12 < antto> "he latest modules now offer theoretical speeds of up to 480 Mbit/s, which will result in a drastically faster experience."
2020-02-19T23:32:30 < qyx> psl
2020-02-19T23:32:44 < antto> wait a minute O_O
2020-02-19T23:32:49 < antto> "Beyond better speed, the STLINK-V3SET and STLINK-V3MINI offer mass storage support to allow for a much more convenient upload process."
2020-02-19T23:33:12 < antto> ah, but that still won't work with a non-ST chip i guess

2020-02-19T23:39:17 < Cracki> nobody really uses this mass storage programming BS
2020-02-19T23:39:36 < Cracki> afaik you drop a bin/elf/hex on the "thumb drive" and it programs the target
2020-02-19T23:39:51 < antto> yeah but i'm desperate
2020-02-19T23:39:58 < antto> in case u didn't notice ;P~
2020-02-19T23:40:01 < Cracki> eh get the dap thingy
2020-02-19T23:40:10 < Cracki> and in the meantime play with that ftdi thing
2020-02-19T23:40:11 < antto> yeah
2020-02-19T23:40:33 < antto> u know how smol t hat sh*t is? i can't even see it x_x
2020-02-19T23:40:36 < Cracki> afaik you need a bunch of resistors to tie together an output pin and input pin so they together can work the swdio line
2020-02-19T23:41:14 < PaulFertser> Oh shit, ft232r driver doesn't support SWD, just JTAG...
2020-02-19T23:41:24 < PaulFertser> Sorry antto 
2020-02-19T23:41:29 < antto> my chip doesn't have JTAG
2020-02-19T23:41:34 < PaulFertser> Yep :(
2020-02-19T23:43:45 < antto> i wonder why DAP-based programmers aren't so popular, on first impression
2020-02-19T23:44:29 < antto> i mean, i found a few old ones and they are "discontinued" or "obsoleted" now
2020-02-19T23:44:52 < antto> now there are only a few options here and there
2020-02-19T23:45:09 < antto> mostly ebay and such
2020-02-19T23:45:13 < Cracki> it's new
2020-02-19T23:45:35 < antto> zl33prg is available on TME as a "new" product and doesn't even come up if you search from octopart
2020-02-19T23:45:43 < Cracki> also smells too enterprisey, too abstract
2020-02-19T23:45:44 < antto> but not in stock on TME
2020-02-19T23:46:18 < Cracki> i've never heard of zl33prg. I have heard of some "implementations" of the dap hardware
2020-02-19T23:46:34 < antto> yeah, neither have i
2020-02-19T23:46:39 < antto> nor about "KAMAMI"
2020-02-19T23:46:53 < Cracki> kamehameha
2020-02-19T23:47:21 < antto> but i saw some reference hardware design for DAPlink with NXP 11U35 or some such, plus a button, plus a few LEDs
2020-02-19T23:47:31 < antto> and this zl33prg seems to be like that
2020-02-19T23:48:21 < antto> and kamami seems to be sorta the polish equivalent of adafruit

2020-02-19T23:52:59 < antto> but that one's moar $$$
2020-02-19T23:53:30 < karlp> DAP was promoted by mbed, everyone else already had a solution, so.... it went big in very limited communities
2020-02-19T23:53:50 < antto> ahumz
2020-02-19T23:54:15 < karlp> before arm even acquired them, iirc, so it was like lpc parts only, and then fsl/nxp merged and.... arm bought mbed, and....
2020-02-19T23:54:18 < antto> but if i understand correctly, the bootloader they use on it would be maybe nice for general usage
2020-02-19T23:54:48 < karlp> stlinkv2.1 plus also offers the "virtual disk" for dropping a firmwar eon to flash,
2020-02-19T23:54:56 < karlp> it's not a cmsis-dap specific feature.
2020-02-19T23:55:07 < antto> right
2020-02-19T23:55:17 < karlp> it wsa "simple" for mbed world, but it's actually ~irrelevant for any other use
2020-02-19T23:55:21 < karlp> you get flashing only via that method,
2020-02-19T23:55:25 < karlp> no debug, no trace...
2020-02-19T23:55:43 < antto> yes
2020-02-19T23:55:55 < antto> for a bootloader for some device that sounds good
2020-02-19T23:56:02 < karlp> well, it wasn't a bootloader...
2020-02-19T23:56:07 < karlp> you could make a bootloader like that
2020-02-19T23:56:13 < antto> firmware update over USB with no speshul drivers or programs needed
2020-02-19T23:56:16 < karlp> but it was a feature of the onboard debugging hardware.
2020-02-19T23:56:33 < karlp> like, the _extra_ part placed on the devboard for doing debug.
2020-02-19T23:56:35 < antto> nah i meant the DAP's bootloader, if i understand correctly
2020-02-19T23:57:05 < karlp> cmsis-dap is a debug interface, supports debug, also supports a mass storage method for dropping a "firmwre.bin" file to reprogram
2020-02-19T23:57:12 < antto> they say "hold that button while plugging the programmer into the USB and you can then update the DAP firmware"
2020-02-19T23:57:15 < karlp> you could probably make a bootloader that was compatible with that if you wanted.
2020-02-19T23:57:37 < karlp> but for instance, ~most of the usb capable stm32s have a rom DFU bootloader
2020-02-19T23:57:48 < karlp> so no need for a DAP style interface
2020-02-19T23:58:16 < antto> which, to me, smells like the programmer also has a bootloader with mass-storage support that doesn't require drivers and programs
2020-02-19T23:58:29 < antto> this kind of bootloader would be kewl for some average device
2020-02-19T23:58:31 < karlp> what?
2020-02-19T23:58:41 < karlp> the programmer doesn't have a "bootloader" 
2020-02-19T23:58:46 < antto> hm
2020-02-19T23:58:52 < karlp> the programmer just has that as it'ðs application.
2020-02-19T23:58:52 < antto> then wat dafuq did i read
2020-02-19T23:59:03 < antto> there's a button on it
2020-02-19T23:59:08 < karlp> sure....
2020-02-19T23:59:10 < antto> hold on, lemme find it
2020-02-19T23:59:27 < karlp> there are many methods....
--- Day changed Thu Feb 20 2020
2020-02-20T00:00:02 < antto> "You can update the ZL33PRG software. To upload/update the device firmware:
2020-02-20T00:00:02 < antto> 1. Disconnect the device and reconnect it with the pressed button on the programmer (photo below). 2. Delete the "firmware.bin" file from the device. 3. Download the latest version of the charge (link provided below). 4. Copy the new file to disk. 5. Disconnect the device and reconnect. "
2020-02-20T00:01:15 < antto> this smells like a bootloader that talks to USB and acts like mass-storage
2020-02-20T00:01:42 < antto> and i doubt KAMAMI developed it, more like it comes from the DAP folks
2020-02-20T00:02:12 < antto> it's probably optional, but they say that the DAP firmware is under developement and constant improvements so it is changing
2020-02-20T00:02:22 < antto> thus updating the DAP firmware is expected
2020-02-20T00:02:29 < antto> so a bootloader seems logical
2020-02-20T00:03:24 < karlp> sure, you might also be able to update the dap fw itself,
2020-02-20T00:03:38 < karlp> and it might appear similar to hwo it presents itself as the programmer
2020-02-20T00:03:49 < karlp> but that's kinda ~side issue 
2020-02-20T00:04:16 < antto> yes, optional
2020-02-20T00:04:46 < antto> but that's why i said that some of the DAPs i found on alieggspress didn't mention any buttons nor firmware update
2020-02-20T00:05:05 < karlp> well, they shoudl be able to reset themselves into bootloader mode if they're any good anyway.

2020-02-20T00:06:27 < antto> these got buttenz
2020-02-20T00:06:35 < karlp> sure, a button works.
2020-02-20T00:06:47 < antto> the chipz are LPC11U35
2020-02-20T00:06:48 < karlp> it's a good failsafe too.
2020-02-20T00:07:00 < karlp> you cna get daplink to run on ~anything.
2020-02-20T00:07:25 < karlp> it's ~similar to blackmagic probe firmware, except instead of appearing as the gdbserver itself like BMP, it presents as a cmsis-dap compatible
2020-02-20T00:07:47 < antto> i mean, the zl33prg is probably a copy of this reference design, made by kamami, without throwing away important stuff like ze button
2020-02-20T00:08:00 < karlp> almost guaranteed, yes.
2020-02-20T00:08:08 < antto> so, smells legit to me then

2020-02-20T00:08:47 < karlp> what have you bought or have on thhe way now?
2020-02-20T00:09:24 < antto> initially bought stlink3mini from mouser together with the whole BOM, and i even designed the board with their silly STDC14 connector

2020-02-20T00:10:19 < karlp> the one that's actually just a ch340 usb-ttl dongle :)
2020-02-20T00:10:22 < karlp> ok, 
2020-02-20T00:10:26 < antto> and received a serial-over-USB
2020-02-20T00:11:01 < antto> but lost like, tons of time.. waiting
2020-02-20T00:11:01 < karlp> cmsis-dap stuff works, I think I only have one of them though, on an atmel d10 board I think
2020-02-20T00:11:18 < antto> board design is from january 1st, had the board in my hands on january 7th
2020-02-20T00:11:25 < antto> still can't blink a LED on it
2020-02-20T00:12:09 < antto> the board has 7 layers of dust on it by now
2020-02-20T00:12:56 < qyx> thats because you are using shitty microchips
2020-02-20T00:13:04 < karlp> hehe
2020-02-20T00:13:04 < qyx> such sam
2020-02-20T00:13:13 < karlp> hanging out in stm32, refuses to use anything we use ourselves ;)
2020-02-20T00:13:53 < antto> i was familiar with SAME54
2020-02-20T00:13:56 < antto> a lil bit
2020-02-20T00:14:18 < antto> i have zero knowlage about any STM chip
2020-02-20T00:15:00 < antto> i just eyeballed some of the datasheets on a few of them (and i didn't like them too much)
2020-02-20T00:15:09  * qyx ordered his first F7
2020-02-20T00:15:16 < karlp> same5 is the one with the big monster list of erratas right? :)
2020-02-20T00:15:29 < antto> i HATE the microsh*ttified SAME54 datasheet, but i had already read many sections of it before this project
2020-02-20T00:15:41 < karlp> "systemet skal tørke minst 10 dager før vannbelastning" takkkkkkk
2020-02-20T00:15:51 < antto> mm, i don't know
2020-02-20T00:16:32 < qyx> wat
2020-02-20T00:16:52  * karlp was hoping to use the bathroom tomorrow or the day after latest, not in 10 days :)
2020-02-20T00:16:55 < qyx> it has to dry at least 10 days before filling with wateR?
2020-02-20T00:17:05 < qyx> or something like that
2020-02-20T00:17:06 < karlp> it's wet room paint.
2020-02-20T00:17:12 < qyx> lol
2020-02-20T00:17:23 < qyx> some latex paint thing?
2020-02-20T00:17:25  * karlp is going to hang up some plastic sheeting I think :)
2020-02-20T00:17:35 < antto> the errata is 45 pages
2020-02-20T00:18:07 < qyx> but at least now I know to say thank you
2020-02-20T00:18:10 < qyx> *how to

2020-02-20T00:23:14 < qyx> the distributor have to make sure there is one inside or they have to translate it and append

2020-02-20T00:24:39 < qyx> so I placed another aisler order
2020-02-20T00:25:01 < qyx> I am curious if it is a good idea to bitbang a LED PWM over i2c using a touch controller GPIO output pin
2020-02-20T00:25:32 < qyx> it should be doable fully in hw using a timer with pwm firing a DMA transfer
2020-02-20T00:25:42 < qyx> or maybe not
2020-02-20T00:26:13 < emeb> anybody know if there are good tools for managing bill of materials?
2020-02-20T00:26:55 < emeb> diptrace just spits out a CSV file and I usually end up massaging it in a spreadsheet, but that's becoming a lot less fun than it used to be.

2020-02-20T02:01:27 < catphish> ah i see

2020-02-20T03:39:46 < kakimir> it has

2020-02-20T03:40:24 < kakimir> those boards have dips next to dips and passives between them
2020-02-20T03:42:21 < jadew> what do you mean by mux all clocks?
2020-02-20T03:42:55 < jadew> what do you want to do?
2020-02-20T03:43:41 < doomba> dips on dips on dips.
2020-02-20T03:44:02 < jadew> ah, you want to switch between feeding two ICs at a time?
2020-02-20T03:45:16 < jadew> why is the propagation delay so important?
2020-02-20T03:46:24 < kakimir> I have limited budget
2020-02-20T03:46:36 < kakimir> no I switch sources to those counters
2020-02-20T03:46:47 < kakimir> because I do data loads to them

2020-02-20T03:54:00 < kakimir> I need same pulse for all counters and in other mode I want TC values from previous counter
2020-02-20T03:54:13 < kakimir> paraller and serial mode
2020-02-20T03:54:46 < kakimir> basically
2020-02-20T03:55:07 < jadew> kakimir, I don't understand what you're trying to do, clock wise
2020-02-20T03:55:32 < jadew> I mean.. if you need to feed two counters at a time, what exactly is stopping you?
2020-02-20T03:55:55 < jadew> or you want to change between two clock sources?
2020-02-20T03:56:42 < jadew> that also sounds like a non-problem
2020-02-20T04:05:43 < kakimir> sources
2020-02-20T04:06:00 < kakimir> I change them between paraller and serial clocking

2020-02-20T08:46:36 < upgrdman> fuck. trying to save live camera stream to disk so it can be replayed later. but it need to be as separate frames, not a video. it takes ~90ms to save each frame raw, or ~102ms to save it as a jpg. surprised it takes so long to dump each ~8MB raw image to my SSD.
2020-02-20T08:47:09 < upgrdman> i guess it time to try polishing this turd with theads to see if that helps ;)
2020-02-20T08:48:07 < jpa-> upgrdman: are you saving into separate files?
2020-02-20T08:48:16 < upgrdman> yes
2020-02-20T08:48:23 < jpa-> yeah, that probably has a lot of overhead
2020-02-20T08:48:37 < jpa-> you could save into a .zip
2020-02-20T08:48:39 < upgrdman> good idea, i'll look into batching
2020-02-20T08:49:06 < upgrdman> would be surprised if 60 files per second is pushing the limited tho
2020-02-20T08:49:36 < jpa-> on most systems, when you close a file it will wait until that file is completely written out
2020-02-20T08:51:32 < upgrdman> hmm
2020-02-20T08:52:31 < jpa-> http://paste.dy.fi/D26/plain  hmm, not much difference, though the speed is as high as one could reasonably expect it to be
2020-02-20T08:55:06 < BrainDamage> upgrdman: if you copy a file from a ramdisk to the ssd, what's the bulk transfer rate?
2020-02-20T08:55:18 < BrainDamage> because you could try writing there and then copy
2020-02-20T08:55:46 < upgrdman> BrainDamage, not sure, but i can regularly do >300MBps between usb3 and ssd. maybe >500MBps?
2020-02-20T08:56:13 < BrainDamage> so write the frames to a ramdisk first
2020-02-20T08:56:24 < upgrdman> ya, looking into it
2020-02-20T08:56:26 < BrainDamage> keep a buffer of n frames and move those in bulk
2020-02-20T08:56:26 < jpa-> on most operating systems it will cache writes automatically anyway - but if it happens to force a flush of caches, you could end up needlessly waiting for that
2020-02-20T08:56:47 < jpa-> adding extra copying through a ramdisk doesn't sound like it would speed things up
2020-02-20T08:56:57 < jpa-> (though it could allow decoupling it to separate threads easier)
2020-02-20T08:57:27 < BrainDamage> while that's correct, any program can trigger a flush of fs caches
2020-02-20T08:57:46 < jpa-> sure, but that shouldn't make other programs wait for the flush to complete AFAIK
2020-02-20T08:58:12 < BrainDamage> at least in lunix, the io scheduler is terrible
2020-02-20T08:58:19 < jpa-> i agree :D
2020-02-20T08:58:27 < jpa-> though there are many terrible options to choose from
2020-02-20T08:59:59 < upgrdman> im kinda surprised it takes ~102ms to make a 1920x1440 jpeg, on my i7.
2020-02-20T09:00:01 < effractur> Take a look at mmaped files
2020-02-20T09:00:21 < effractur> upgrdman: probaly depends on the compression level
2020-02-20T09:00:25 < upgrdman> is webp or whatever faster to encode/decode?
2020-02-20T09:00:30 < jpa-> upgrdman: what jpeg library are you using, there is a lot of difference
2020-02-20T09:00:55 < upgrdman> jpa-, just the one in java... ImageIO.write(shit);
2020-02-20T09:01:05 < upgrdman> guess i should look into the options
2020-02-20T09:01:08 < BrainDamage> there should also be gpu codecs, if the weight of dma transfer there isn't too horrible
2020-02-20T09:01:25 < effractur> upgrdman: using buffered I/O?
2020-02-20T09:01:30 < effractur> in java?
2020-02-20T09:01:32 < jpa-> libjpeg-turbo is semiok AFAIK, but GPU accelerated ones might be even faster

2020-02-20T09:01:52 < upgrdman> oh shit why didnt i think of that. ya, i should see how hard it's be to have the gpu do it.
2020-02-20T09:02:00 < upgrdman> im already using the gpu to show it live
2020-02-20T09:02:16 < upgrdman> so the bytes are already sitting on the gpu ready to be molested
2020-02-20T09:02:28 < effractur> sortof
2020-02-20T09:02:30 < effractur> probaly not
2020-02-20T09:02:45 < upgrdman> effractur, and yes, using ByteBuffers

2020-02-20T09:10:41 < dongs> upgrdman: webp (and any high-end image compression) is much more cpu intensive to compress
2020-02-20T09:10:59 < upgrdman> k
2020-02-20T09:10:59 < dongs> the idea is that you can spend more time compressing and less decompressing
2020-02-20T09:11:22 < upgrdman> is there a codec that is faster to encode, even if not as good at compressing?
2020-02-20T09:13:22 < dongs> lossless stuff probably but then you dont get as much space
2020-02-20T09:15:02 < upgrdman> PNG was much slower :)
2020-02-20T09:15:17 < dongs> for sure
2020-02-20T09:15:20 < upgrdman> but ya, looking into other jpg libs, and if there are any settings i can tweak
2020-02-20T09:15:23 < dongs> some LZ* or whaever derivative
2020-02-20T09:15:28 < dongs> for lossless
2020-02-20T09:15:34 < dongs> but of course that would have no optimizations for images

2020-02-20T10:39:04 < Ad0> hello, I wonder what's best, to change bit order to LSB in the SP device, or to reverse the bits myself, since ARM is LSB
2020-02-20T10:39:12 < Ad0> SPI*
2020-02-20T10:42:02 -!- drzacek [~drzacek@b941c009.business.dg-w.de] has joined ##stm32
2020-02-20T10:42:20 < Ad0> setting LSB in the SPI device makes the communication match the literal struct layout which is nice
2020-02-20T10:42:58 < dongs> arm has REV16 or whatever thats a one-instruction to swap
2020-02-20T10:44:53 < Ad0> yeah I read about rbit also
2020-02-20T10:45:12 < Ad0> but would you rather do it in code instead of changing the SPI communication to LSB?
2020-02-20T10:45:39 < jpa-> Ad0: what bit order are any commands & register addresses sent over SPI to that device?
2020-02-20T10:46:34 < Ad0> it has 2 16 bit chunks, where the first bit to come in is 16... then 0 in the end
2020-02-20T10:46:59 < Thorn> that's 17 bits
2020-02-20T10:47:09 < Ad0> I mean 15
2020-02-20T10:47:16 < Ad0> command is the first bit. 5 bits for don't care, then 10 for the address
2020-02-20T10:47:58 < jpa-> so it transfers that MSB first, but then the data is LSB first?
2020-02-20T10:48:30 < Ad0> so I made a bitfield struct { uint16_t Read : 1; uint16_t : 5; uint16_t Address : 10; uint16_t Data; }
2020-02-20T10:48:55 < Ad0> jpa-, yeah
2020-02-20T10:49:17 < Ad0> ARM is LSB
2020-02-20T10:49:30 < jpa-> the cpu endianess has no relevance for this
2020-02-20T10:49:36 < Thorn> iirc stm32 spi transfers bytes msb first by default
2020-02-20T10:50:00 < Ad0> Thorn, I changed it to LSB and then it looks OK on the logic analyzer, the command bit comes first based on that struct layout
2020-02-20T10:50:16 < Ad0> without any bit reversing
2020-02-20T10:50:31 < jpa-> bitfield struct layout is a bit unportable anyway, i wouldn't use it for stuff like this
2020-02-20T10:51:23 < Ad0> jpa-, but it's nice though :/ it's not like I am gonna change platforms and architecture "just like that"
2020-02-20T10:51:52 < Ad0> it's implementation specific indeed
2020-02-20T10:52:24 < Ad0> if it changes between versions of GCC then I have a problem :)
2020-02-20T10:52:30 < Ad0> but then what use is a bitfield
2020-02-20T11:02:46 < jpa-> i find myself porting driver code for SPI devices from processor to another quite often
2020-02-20T11:03:12 < jpa-> but of course, one can always deal with that later
2020-02-20T11:03:20 < Ad0> then I would do it in software no doubt
2020-02-20T11:06:02 < jpa-> c has many features you'd never want to use anyway :)
2020-02-20T11:06:25 < jpa-> like 'abcd'

2020-02-20T15:03:36 < dongs> Deployment times are accelerated further still through the use of Altium Designer and the Altium 365 Cloud Platform for hardware design. SMBs and design professionals using Altium Designer can now leverage a range of Arduino reference design assets, from validated component symbols and footprints to schematic and layout templates and examples, making it faster and simpler than ever to create custom hardware

2020-02-20T15:05:58 < karlp> that portenta-h7 is the a365 viewer I was talking about yesterdya, seems pretty neat, compared to gettingjust a pdf
2020-02-20T15:06:53 < srk> haha, wish they announce official partnership with altium
2020-02-20T15:07:44 < karlp> it's apparently meant to be a not-just-altium "portable" viewer
2020-02-20T15:08:19 < karlp> supports altium and eagle now, adding kicad apparently
2020-02-20T15:08:25 < dongs> meanwhile kikecad retards are still poking along with decade old shit
2020-02-20T15:08:46 < doomba> i like kicad though because i'm poor and altium is for cokeheads
2020-02-20T15:09:12 < karlp> what do you mean by decade old shit now?
2020-02-20T15:09:23 < dongs> kikecad
2020-02-20T15:09:30 < dongs> the "pcbnew" thing has been same for decades
2020-02-20T15:09:36 < dongs> old crusty shit code that can't work with anything modern
2020-02-20T15:09:44  * karlp shrugs. if you say so
2020-02-20T15:09:44 < dongs> they can't add new shit because old shit is garbage
2020-02-20T15:09:48 < dongs> and nobody wants to work on it
2020-02-20T15:10:07 < srk> bullshit :)
2020-02-20T15:10:43 < srk> I'm sure ppl buy altuim for features like animated board flips
2020-02-20T15:10:45 < dongs> well altium is on version 20 now
2020-02-20T15:10:49 < dongs> kikecad is what, 0.000010?
2020-02-20T15:10:51 < srk> oh wow
2020-02-20T15:11:06 < dongs> they always haev new shit
2020-02-20T15:11:07 < srk> like the version number ever means anything :)
2020-02-20T15:11:16 < dongs> 3D board flips are quite important, 3d component stuff in general
2020-02-20T15:11:17 < Cracki> it's the current year
2020-02-20T15:11:22 < dongs> for clearance/assembly/etc
2020-02-20T15:11:32 < dongs> its not just "wow look my shit is in 3d"
2020-02-20T15:11:54 < dongs> i can give my enclosure guy a .step of entire board
2020-02-20T15:12:02 < dongs> and he can design teh shit around it to make sure stuff fits 
2020-02-20T15:12:04 < srk> yeah, making your 2D CAD unusable due to 3d flip animation is a way to go xD
2020-02-20T15:12:11 < dongs> good luck doing any mcad integration with kikecad
2020-02-20T15:12:18 < dongs> can it even output entire board view as step?
2020-02-20T15:12:28 < srk> mcad?
2020-02-20T15:12:57 < srk> you have freecad plugins for import, no need for step
2020-02-20T15:13:52 < Cracki> step is a nice interchange format. now the freecad plugin has to chase whatever file formats ecad programs out there generate
2020-02-20T15:13:55 < dongs> mechanical cad. i.e. solidworks/autocad/wahtever 3d shit the professionals use
2020-02-20T15:13:58 < dongs> not fucking freeSCAT
2020-02-20T15:14:22 < dongs> srk, if I make a board in kikecad and i need to give its 3d file to enclosure guy, what do i do?
2020-02-20T15:14:25 < Cracki> as always, thinking about interfaces isn't the strong suit of open source
2020-02-20T15:14:29 < dongs> in altium its literally one click process
2020-02-20T15:14:31 < dongs> kikecad?
2020-02-20T15:15:45 < srk> well there's kicad stepup if you really need step

2020-02-20T15:17:23 < srk> gonna try rendering some stuff with blender 
2020-02-20T15:18:10 < srk> made this one recently https://raw.githubusercontent.com/sorki/anomaly/master/renders/final.png
2020-02-20T15:18:23 < karlp> dongs: yes, you can output entire board as step, I've done that a few times to make nice 3d models for stcks/combinations.
2020-02-20T15:18:34 < srk> with pro blender freecad importer plugin
2020-02-20T15:18:51 < srk> karlp: no need for plugins anymore?
2020-02-20T15:19:12 < karlp> nope.
2020-02-20T15:19:12 < kakigate> blender kicad :o
2020-02-20T15:19:20 < srk> nice
2020-02-20T15:22:26 < karlp> https://imgur.com/a/hiYqWei
2020-02-20T15:23:38 < srk> yeah, have it installed now, takes a while to grab all the 3d models /o
2020-02-20T15:24:11 < karlp> I just have a bunch of "not appropriately licensed" files locally, 
2020-02-20T15:24:16 < karlp> I'm not making my own 3d models or anything
2020-02-20T15:24:39 < srk> no, upstream ones are like 4Gigs
2020-02-20T15:25:13 < karlp> ah, yeah, I cloned that ages ago, pulls aren't so bad these days to update it.
2020-02-20T15:25:48 < srk> hah, blender won't load STEP xD
2020-02-20T15:30:25 < srk> can do VRML but without components
2020-02-20T15:32:18 < dongs> haha opensores trash still clings to VRML
2020-02-20T15:32:23 < dongs> literally nothing uses it anymore
2020-02-20T15:43:52 < benishor> you're so full of .. dong
2020-02-20T15:44:22 < benishor> vrml is a common denominator so it's only natural to be used when transitioning between apps that support exporting/importing to/from vrml
2020-02-20T15:44:59 < benishor> and kicad is way better than your sorry ass will ever be able to write
2020-02-20T15:46:47 < benishor> granted, code is still messy in parts and it's one hell of a job working with legacy code, but it's evolving and adding awesome features to be used by users for free, in a crossplatform independent setup
2020-02-20T15:47:16 < karlp> benishor: are you new here? :)
2020-02-20T15:47:35 < benishor> karlp: no, I just feel the need to bitchslap dongs at times :)
2020-02-20T15:47:40 < jpa-> i won't miss vrml, and it would be nice if blender had a working step import :)
2020-02-20T15:48:23 < benishor> karlp: must be the balcan spirit :)
2020-02-20T15:50:51 < jpa-> in other news, freecad's CAM side has been developing fast in the past years
2020-02-20T15:51:16 < benishor> I found freecad to have a very steep learning curve
2020-02-20T15:51:22 < jpa-> me too
2020-02-20T15:51:29 < benishor> still trying to get something usable out of it
2020-02-20T15:51:31 < jpa-> i still only know how to use the CAM stuff
2020-02-20T15:51:33 < benishor> didn't manage to yet
2020-02-20T15:51:42 < jpa-> cannot model anything with it, i use solvespace for modelling
2020-02-20T15:51:56 < dongs> benishor: do you know what "cross-platform" means
2020-02-20T15:52:09 < jpa-> "sucks on every platform"?
2020-02-20T15:52:11 < dongs> it means, "equally shitty on every platform it claims to support"
2020-02-20T15:52:12 < dongs> yes
2020-02-20T15:52:16 < benishor> jpa-: fusion 360 seems to be all the craze naw
2020-02-20T15:52:16 < jpa-> like a very sexy gf
2020-02-20T15:52:17 < dongs> jpa is pro
2020-02-20T15:52:28 < benishor> dongs: jpa is pro, you are not.
2020-02-20T15:52:31 < benishor> so stfu
2020-02-20T15:53:08 < jpa-> benishor: yeah, but i stay away from fusion360 because 1) windows, 2) might disappear suddenly
2020-02-20T15:53:20 < benishor> jpa-: it also works on macs
2020-02-20T15:53:33 < benishor> it's got some very intuitive modelling tools
2020-02-20T15:53:37 < dongs> why would a normal human being care about a mac
2020-02-20T15:53:43 < benishor> you can see all the experience autodesk has
2020-02-20T15:54:02 < benishor> because a mac lies somewhere between windows and linux
2020-02-20T15:54:06 < dongs> no
2020-02-20T15:54:25 < dongs> owning or using a mac just means youre a fucking faggot, full stop
2020-02-20T15:54:26 < dongs> there's no excuse
2020-02-20T15:54:36 < benishor> and corporations tend to give macs to devs because they support ms exchange ecosystem
2020-02-20T15:54:43 < karlp> dongs: careful, even thorn has a mac now ;)
2020-02-20T15:54:51 < effractur> bpm
2020-02-20T15:54:56 < benishor> and those you can make your own after some years of use
2020-02-20T15:55:00 < benishor> for a very modest amount
2020-02-20T15:55:10 < jpa-> i have a macbook in my drawer also.. the enter key has stopped working on it though :/
2020-02-20T15:55:16 < karlp> benishor: evolution works perfectly well with exchange these days, has done for years really, even with office365.
2020-02-20T15:55:28 < karlp> (what _doesn't_ work on linux in the ms ecosystem is fucking teams)
2020-02-20T15:55:38 < benishor> karlp: it's not evolution alone. things like lync and shit
2020-02-20T15:55:47 < benishor> sure, pidgin sipe made an attempt but miserably failed
2020-02-20T15:55:52 < karlp> depends which parts your company is using.
2020-02-20T15:56:05 < benishor> most of companies make sure they use every bit of what they pay for :)
2020-02-20T15:56:05 < jpa-> how well does office365 web version work on linux nowadays? so far i've been using libreoffice for all work stuff, but there is always some risk of incompatibilities
2020-02-20T15:56:07 < karlp> google meetings works flawlessly onlinux, teams is a fucking garbage fire.
2020-02-20T15:56:22 < benishor> yeah, teams is a shit on yet another shit
2020-02-20T15:56:27 < karlp> jpa-: I use both, libreoffice and online web stuff, works fine enough for what i'm doing at least.
2020-02-20T15:56:28 < jpa-> for meetings i just use the android clients
2020-02-20T15:56:31 < benishor> yet they all push it as lync successor
2020-02-20T15:56:53 < karlp> jpa-: fine for listening in, worthelss for presenting anything though.
2020-02-20T15:57:08 < jpa-> true
2020-02-20T15:57:38 < karlp> I can actually get audio in teams, and video of the remote user, but I just get a black box when they rpesent, and no-body can see my video, even though it shows my video preview.
2020-02-20T15:57:40  * karlp shrugs
2020-02-20T15:57:55 < benishor> just one of them things :)
2020-02-20T15:57:56 < karlp> had an MS person join, they want to push more of it.
2020-02-20T15:58:13 < benishor> they should shovel the shit
2020-02-20T15:58:21 < karlp> well, it works well for them and what they want :)
2020-02-20T15:58:37 < karlp> but teams is definitively worse than slack, 
2020-02-20T15:58:39 < benishor> their market share is pretty big with corporations
2020-02-20T15:58:46 < benishor> slack is bad for scaling
2020-02-20T15:58:50 < karlp> and slack wasn't great.
2020-02-20T15:59:03 < benishor> ms at least has this large ecosystem encompassing everything
2020-02-20T15:59:12 < karlp> yeah, where it's all equally shit :)
2020-02-20T15:59:12 < benishor> mail, calendar, active directory and so on
2020-02-20T15:59:20 < benishor> so it's either ms or google 
2020-02-20T15:59:21 < karlp> and it's all built on top of sharepoint
2020-02-20T15:59:30 < benishor> don't even get me started on sharepoint
2020-02-20T15:59:36 < karlp> I'm not a google fanboi, but ffs, it at least normally _works_ 
2020-02-20T16:00:10 < karlp> teams chat is the worst though, ifyou typ and press enter, it makes "new conversations" each time
2020-02-20T16:00:22 < karlp> if you click in the "reply" box, after a couple of them it collapses all the messges, 
2020-02-20T16:00:32 < karlp> so you can't even scroll to read the backlog of your _work_ chat
2020-02-20T16:00:35 < benishor> so here's my transceiver finally listening to real band https://www.youtube.com/watch?v=E5um9sQ-cYM
2020-02-20T16:00:39 < karlp> it's just continusouly reclicking to open shit
2020-02-20T16:00:51 < benishor> still got quirks to solve but it's working
2020-02-20T16:01:07 < karlp> and teams added their _own_ fucking wikis and notebooks, which are _like_ sharepoint+onenote, but _not_
2020-02-20T16:01:58 < karlp> but it's ok, because "my analytics, wellness edition" tells me I had 93% of my time to focus, because it only understands what's put into outlook :)
2020-02-20T16:03:51 < aandrew> benishor: Nice. STM32 is doing the demod?
2020-02-20T16:04:03 < aandrew> Teams sucks period
2020-02-20T16:05:53 < benishor> aandrew: yes, stm32 is doing the demod, controlling the si5351 vfo, display and such
2020-02-20T16:06:25 < aandrew> Very nice. I’m struggling with gnuradio a lot
2020-02-20T16:06:48 < benishor> aandrew: I'm just after building my own transceiver top to bottom
2020-02-20T16:07:05 < benishor> it's a learning experience
2020-02-20T16:07:15 < benishor> actually it's my first stm32 project, still lots to be fixed

2020-02-20T16:55:05 < kakimir> it has separate voltage for output drivers
2020-02-20T16:55:12 < karlp> there's quite a few...
2020-02-20T16:55:19 < srk> silabs something
2020-02-20T16:55:19 < karlp> there's hc series stuff even.
2020-02-20T16:55:33 < karlp> if you're thinking silabs you're probably thinking of their isolators,
2020-02-20T16:55:44 < kakimir> no isolators
2020-02-20T16:55:44 < karlp> which may or may not be what kakstar realyl wanted?
2020-02-20T16:55:50 < kakimir> it's not

2020-02-20T16:56:08 < kakimir> line driver
2020-02-20T16:56:54 < aandrew> Level translator, line driver, output buffer...

2020-02-20T16:59:55 < karlp> also hct125
2020-02-20T17:00:36 < karlp> 245 is fulyl dual supply
2020-02-20T17:00:53 < karlp> hct125 is just a buffer, but lets you do 3.3 to 5 sort of translation...
2020-02-20T17:02:21 < BrainDamage> it's more problematic when the bus is bidirectional
2020-02-20T17:02:38 < jpa-> just need to switch the direction of the translator also
2020-02-20T17:03:29 < jpa-> 74AXCH8T245 is also nice in that you can have 4 bits in one direction and 4 bits in other direction

2020-02-20T17:05:30 < fenugrec> HEF4104 / CD40109 if you need low-to-high in CMOS voltage ranges...
2020-02-20T17:08:31 < benishor> use some fets?
2020-02-20T17:09:11 < benishor> I assume you want level shifting?
2020-02-20T17:09:52 < jpa-> the T245 series chips are cheap, easy to use and there is a bunch of models to choose, and they'll work better than any fet + pull-up hodgebodge

2020-02-20T17:10:47 < karlp> those are the i2c ones arne't they?
2020-02-20T17:10:53 < karlp> they're not necessarily the same thing.
2020-02-20T17:11:34 < Thorn> https://www.etlcpp.com/ works
2020-02-20T17:11:35 < benishor> I don't believe these should be used for i2c from what the datasheet says
2020-02-20T17:11:37 < jpa-> i think they work for other signals also, if the direction autosensing doesn't get in the way
2020-02-20T17:11:54 < jpa-> but yeah, those txb0102 chips are often used for i2c i think
2020-02-20T17:12:31 < benishor> funny how they go against the datasheet specifications :)
2020-02-20T17:13:04 < jpa-> how so?
2020-02-20T17:13:17 < jpa-> ah
2020-02-20T17:13:21 < benishor> https://imgur.com/a/dCd7i32
2020-02-20T17:13:28 < jpa-> "For the same reason, the TXB0102 device must not be used in applications such as I2C or 1-Wire where an
2020-02-20T17:13:28 < jpa-> open-drain driver is connected on the bidirectional data I/O. For these applications, use a device from the TI

2020-02-20T18:17:06 < jadew> Cracki, I contacted that Romanian PCB house
2020-02-20T18:17:33 < jadew> 82 USD  for 14 x 50x30 mm boards
2020-02-20T18:17:39 < jadew> without shipping
2020-02-20T18:18:36 < jadew> subsequent orders would be $22 cheaper, because you wouldn't pay for the photo transfer films again
2020-02-20T18:18:50 < jadew> not a particularly good deal
2020-02-20T18:25:48 < doomba> romanians have legit biz?
2020-02-20T18:26:00 < qyx> ok, jlcpcb arrived
2020-02-20T18:26:11 < qyx> treated with sodium hypochlorite
2020-02-20T18:26:19 < qyx> now baking at 150C
2020-02-20T18:26:24 < doomba> qyx: WTF lol
2020-02-20T18:26:28 < doomba> you THAT worried bro?
2020-02-20T18:26:45 < qyx> it was in transit 6 days only
2020-02-20T18:26:52 < jadew> sounds reasonable
2020-02-20T18:26:59 < jadew> so jlcpcb is working again?
2020-02-20T18:27:03 < qyx> seems so
2020-02-20T18:27:05 < doomba> and the WHO says 9 days right?
2020-02-20T18:27:11 < jadew> when did you order them?
2020-02-20T18:27:20 < Thorn> jadew: $57 @ https://www.rezonit.ru/ lol
2020-02-20T18:27:26 < jadew> doomba, WHO says whatever the chinese gvt tells them to say
2020-02-20T18:27:30 < doomba> still - i think even after 6 days it's probably still safe
2020-02-20T18:27:46 < jadew> apparently it can survive outside of the body up to 28 days
2020-02-20T18:28:06 < qyx> jadew: 2020-01-21
2020-02-20T18:28:20 < doomba> your pcbs are just a pin head in a galaxy-sized bin of china crap that is shipped into your country every day - most of it arriving from china in 1 or 2 days time.
2020-02-20T18:28:40 < doomba> and all the mail couriers and supermarket shelve stockers etc. they're all touching that china shit all day every day without washing their hands or anything
2020-02-20T18:28:42 < jadew> Thorn, with VAT, that becomes 70
2020-02-20T18:29:06 < jadew> and if you add shipping, it's probably going to be more expensive than the local option
2020-02-20T18:29:14 < jadew> I'm tempted to use them to see what the quality is like
2020-02-20T18:29:20 < doomba> if it was really an issue, every country ESPECIALLY the USA would be full blown 28 days later already
2020-02-20T18:29:31 < qyx> yeah
2020-02-20T18:29:36 < qyx> I am just paranoid
2020-02-20T18:29:39 < Thorn> I believe vat is included
2020-02-20T18:30:24 < jadew> Thorn, what's the VAT in russia?
2020-02-20T18:30:26 < doomba> qyx: did you get a gift in your order?
2020-02-20T18:30:31 < jadew> because they would have to take that off
2020-02-20T18:30:40 < qyx> no
2020-02-20T18:30:41 < doomba> i usually get a ruler or a little trinket. last time i got a heart keychain
2020-02-20T18:30:52 < jadew> doomba, they spit on every package tho
2020-02-20T18:31:13 < doomba> imma laugh my ass off if this time i get barely-wrapped candy
2020-02-20T18:31:28 < jadew> really?
2020-02-20T18:31:31 < doomba> corona gum drops
2020-02-20T18:31:31 < jadew> I never get anything
2020-02-20T18:31:36 < doomba> no?
2020-02-20T18:31:47 < Thorn> "due to the virus mass production is overloaded but prototype orders are still being manufactured on time" https://www.rezonit.ru/news/informiruem-o-tekushchey-situatsii-s-zagruzkoy-proizvodstva-pechatnykh-plat/
2020-02-20T18:31:57 < jadew> yep, and had several orders of > $100 from them
2020-02-20T18:32:02 < doomba> wtf
2020-02-20T18:32:16 < doomba> https://salcedo.tech/projects/cluster/controller-v01-pcb.jpg
2020-02-20T18:32:20 < jadew> maybe you have an admirer there
2020-02-20T18:32:33 < doomba> they sent me that with a small order around $10
2020-02-20T18:32:47 < jadew> they must hate romanians
2020-02-20T18:32:53 < jadew> but it's ok, I don't like their boards either
2020-02-20T18:33:10 < doomba> well tbf all you .rotards are using stolen CCs so maybe that's why china hates you
2020-02-20T18:33:19 < jadew> haha
2020-02-20T18:33:34 < jadew> we don't have thieves anymore
2020-02-20T18:33:38 < Thorn> jadew: 20%
2020-02-20T18:34:03 < jadew> Thorn, hmm, it's worth considering then
2020-02-20T18:34:08 < jadew> I'll keep it on my list
2020-02-20T18:34:37 < doomba> i wonder if maybe it's the shipping method
2020-02-20T18:35:07 < doomba> it could be they only put the gift items when you use postlink or w/e
2020-02-20T18:35:24 < jadew> I always use DHL
2020-02-20T18:35:45 < doomba> yea maybe they don't do it with DHL because of cost
2020-02-20T18:36:08 < doomba> even though adding a 0.001g thing is no big deal - it probably adds up when they're sending out millions of orders per month
2020-02-20T18:36:55 < jadew> I've decided against jlcpcb anyway
2020-02-20T18:37:12 < jadew> I think I was able to use only 30% of their boards
2020-02-20T18:37:33 < karlp> that's because you're trying to use $2 pcbs for your 10GHz lunacy,
2020-02-20T18:37:34 < jadew> the rest had various aesthetic flaws
2020-02-20T18:38:05 < jadew> karlp, well, if it works...
2020-02-20T18:38:12 < karlp> well it did for 70%.
2020-02-20T18:38:17 < karlp> soudnsd pretty good to me really...
2020-02-20T18:39:07 < jadew> I think I did the math at some point, and I think I'm paying between 5 and 10 USD for one PCB when I'm buying from China
2020-02-20T18:39:51 < jadew> so it's definitely possible to make them somewhere else
2020-02-20T18:39:59 < karlp> that doesn't sound like 70% pcbs, or it sounds like you're factoring your dhl hate into it
2020-02-20T18:40:09 < jadew> karlp, I am, yeah
2020-02-20T18:40:20 < jadew> but I said 30%, not 70%
2020-02-20T18:40:36 < karlp> my bad, right
2020-02-20T18:40:41 < jadew> 70% were bad (scratched, missing parts of the silkscreen, really ugly solder mask)
2020-02-20T18:41:07 < karlp> this also only matteres again because you wanted to use the PCB as the product didn't you?
2020-02-20T18:41:21 < karlp> you have exceptional requirements for someone who doesn't want to pay for anything :)
2020-02-20T18:41:22 < jadew> I had better success with elecrow, but their silkscreen gets a yellow tint when baked
2020-02-20T18:41:32 < jadew> karlp, yeah
2020-02-20T18:41:45 < jadew> if they were hidden in a box it wouldn't have mattered
2020-02-20T18:42:32 < jadew> I want to pay, but I want to pay as little as possible :P

2020-02-20T19:47:23 < Cracki> jadew, sad to hear it's not competitive. still, 4-6 usd for a 3x5 cm board sounds "tolerable". in case china is wiped out entirely and nobody dares move in and operate the pcb factories, you have local fallback :D
2020-02-20T19:48:35 < Cracki> as for aisler... just today I saw a BROKEN pcb that should have been caught by etest AND even the laziest visual inspection
2020-02-20T19:48:52 < Cracki> and today means it was delivered days ago, not years ago
2020-02-20T19:55:07 < jpa-> jadew: funny, for me the jlcpcb silkscreens and soldermasks have been pretty much perfect always
2020-02-20T19:55:19 < jpa-> but on the other hand, most of my boards are 4 layers so maybe it is a better process
2020-02-20T20:03:09 < aandrew> https://www.embeddedonlineconference.com/index.php might be interesting to some of you here. free reg until end of feb
2020-02-20T20:03:12 < aandrew> online conf
2020-02-20T20:05:17 < Cracki> oh there's some embedded conference in germany, regensburg I think
2020-02-20T20:05:29 < jadew> Cracki, yeah, but they seem in line with the other EU PCB houses
2020-02-20T20:06:12 < jadew> jpa-, yeah, that could be it
2020-02-20T20:07:04 < jadew> aandrew, thanks
2020-02-20T20:07:24 < Cracki> aisler quality control missed this https://twitter.com/FauthNiklas/status/1230205856932941824
2020-02-20T20:08:47 < jadew> jeez...
2020-02-20T20:09:08 < Cracki> they've been around a few years.
2020-02-20T20:09:41 < Cracki> if their milling can cause *this*, I would instate automated optical inspection.
2020-02-20T20:10:37 < Cracki> I would have expected their response to be like "we're terribly sorry, pls give us the order number and we'll send you some more boards right away free of charge"
2020-02-20T20:10:47 < Cracki> maybe I missed that.
2020-02-20T20:15:18 < Cracki> AOI also to keep evidence of the state of the wares before shipping
2020-02-20T20:15:33 < jpa-> jadew: have you tried multi-circuit-boards.eu? i have one pcb arriving from them next week
2020-02-20T20:15:59 < jadew> jpa-, I have not, but I just clicked on their URL (recommended from that twitter feed)
2020-02-20T20:16:18 < Cracki> ah, I judged too soon. they did ask to have a call with him about this
2020-02-20T20:16:24 < jadew> I think I'll eventually try all of the european ones
2020-02-20T20:16:26 < jpa-> calculator shows 64 for your 14x 50x30
2020-02-20T20:16:47 < jadew> I'm going to start with the Romanian one
2020-02-20T20:17:16 < Cracki> you can break their kneecaps in person *g*
2020-02-20T20:17:20 < jadew> jpa-, yeah, that's inline with others
2020-02-20T20:17:24 < jadew> Cracki, lol
2020-02-20T20:17:40 < jadew> the advantage with the Romanian one is that I can actually pick up the boards myself if I want to
2020-02-20T20:18:01 < jadew> or have them shipped to my door with same day delivery for less than $5
2020-02-20T20:18:03 < qyx> Cracki: where, pics
2020-02-20T20:18:15 < jadew> so that can be factored in too
2020-02-20T20:18:16 < Cracki> yeh that can easily shave off a day or two compared to having it going through delivery
2020-02-20T20:18:19 < qyx> Cracki: someone mentioned reception of a pcb with a broken trace
2020-02-20T20:18:23 < Cracki> https://twitter.com/AislerHQ/status/1230240089588015105
2020-02-20T20:18:46 < Cracki> broken trace was days ago and I don't remember who and what pcb fab
2020-02-20T20:18:51 < Cracki> this is a broken board
2020-02-20T20:19:14 < Laurenceb> ur back
2020-02-20T20:19:21 < jadew> jpa-, that multi-cb house looks good
2020-02-20T20:19:25 < Laurenceb> so you didnt kill ur mum
2020-02-20T20:19:35 < jadew> 10 euro stencils
2020-02-20T20:20:13 < jpa-> jadew: yeah, and only ~200 euros for a custom process (though jlcpcb would have had pooling for 0.8mm boards also)
2020-02-20T20:20:19 < Laurenceb> kill the truks cuz secrit underground aliens
2020-02-20T20:20:25 < Laurenceb> makes so much sense
2020-02-20T20:24:15 < Cracki> hm, one aisler customer claims they can do 4 mil traces (0.1mm) and 0.2mm vias as "standard"
2020-02-20T20:24:55 < qyx> I would not be surprised, quality of the board is not bad
2020-02-20T20:25:09 < qyx> but as I can see they may have communication issues
2020-02-20T20:25:29 < jpa-> Cracki: matches jlcpcb standard specs
2020-02-20T20:25:37 < jpa-> (for 4 layers, that is)
2020-02-20T20:25:42 < Cracki> good to know
2020-02-20T20:26:05 < Cracki> all I ever needed was the 2 bucks supersupercheap option they have
2020-02-20T20:26:17 < jpa-> jlcpcb claims 0.09mm, but refuses boards that have too many traces less than 0.10mm
2020-02-20T20:26:58 < Cracki> sounds like yield struggle

2020-02-20T20:48:40 < Cracki> nice. ordered a "jlink ob" (f072 based) from aliex. appears to work, also has vcom. nice size for sticking in a pocket
2020-02-20T20:48:53 < Cracki> antto, decided what to get yet?
2020-02-20T20:49:16 < antto> it's already in fedeggz

2020-02-20T20:50:14 < Cracki> if you decide you want one, this is what I got https://www.aliexpress.com/item/4000249803796.html
2020-02-20T20:50:16 < antto> eggspected deliver on 27th feb
2020-02-20T20:50:54 < antto> i tossed too much moniez for programmers already
2020-02-20T20:53:46 < Cracki> I tossed money on shit when I started too
2020-02-20T20:54:15 < antto> yeah but a pile of time passed too
2020-02-20T20:54:16 < Cracki> I still have this "ulink" that I remember works with _one_ IDE and I never bothered since the jlink clone works so well
2020-02-20T20:54:23 < antto> now i tossed 53 euro at kamami
2020-02-20T20:54:28 < Cracki> o.o
2020-02-20T20:54:30 < Cracki> that's a bunch
2020-02-20T20:54:50 < antto> 14 programmer, 6 for an adapt0r, 33 for fedeggz
2020-02-20T20:55:00 < Cracki> as for time, think like a dragon. dragons live forever. a century is but a blip
2020-02-20T20:55:04 < Steffanx> moneyed westener this antto :P
2020-02-20T20:55:20 < antto> no, raging ghetto thugg
2020-02-20T20:56:12 < antto> the only positive thing about this is that my cat is very amused by the animation of the "Ask fedex" button on their website
2020-02-20T20:56:30 < antto> she eyeballz it
2020-02-20T20:56:50 < Cracki> pet her
2020-02-20T20:57:04 < antto> nah
2020-02-20T20:57:28 < Steffanx> hm
2020-02-20T20:57:31 < antto> not now when she's busy
2020-02-20T20:57:39 < Steffanx> Arent you a good petter?
2020-02-20T20:57:55 < Cracki> you know why segger is king? example: their jlink support software updates the dlls in OTHER APPLICATION DIRECTORIES. it scans what you have and finds its own shit and offers to update it.
2020-02-20T20:58:10 < antto> yes, but when i'm on teh comput0r she gets all in my face and i can't even type on muh keyboard
2020-02-20T20:58:20 < Cracki> truestudio/cubeide, keil, atmel studio, ...
2020-02-20T20:58:31 < Cracki> use her as a palm rest
2020-02-20T20:58:32 < antto> Cracki sounds like a virus
2020-02-20T20:58:46 < antto> jlink-o-rona virus
2020-02-20T20:58:56 < Steffanx> Except that ozone 3.10d craps out and starts to eat of of my RAM
2020-02-20T20:59:09 < Cracki> sounds like they know other vendors dgaf and they themselves have to make sure to keep their stuff working well
2020-02-20T20:59:16 < Steffanx> And latest systemview does weird stuff too
2020-02-20T20:59:45 < antto> i honestly don't like the situation with these segger tools, too complicated
2020-02-20T20:59:46 < antto> meh
2020-02-20T20:59:58 < antto> DAP sounds simpler and better to me
2020-02-20T20:59:59 < Steffanx> It thinks my idle task uses 11231254738957623874% of the available time.
2020-02-20T21:00:06 < Steffanx> segger is damn simple
2020-02-20T21:00:10 < Steffanx> jlink that is
2020-02-20T21:00:13 < antto> maybe jlink is all about being eggcelent and much PRO
2020-02-20T21:00:18 < antto> but i'm ghetto, so.. meh
2020-02-20T21:00:31 < Steffanx> open ozone, clickerly click through the wizard.
2020-02-20T21:00:33 < Steffanx> start debugging
2020-02-20T21:00:51 < antto> haven't even heard about ozone
2020-02-20T21:01:22 < Steffanx> hm
2020-02-20T21:01:28 < antto> if i understand correctly, the jlink itself has to support a given target chip, right?
2020-02-20T21:01:40 < Cracki> you build an elf somehow. ozone takes that and a jlink debugger, and you can debug your target with that
2020-02-20T21:01:56 < Cracki> not quite

2020-02-20T21:02:28 < Steffanx> and ozone is nicely fast with reprogramming.
2020-02-20T21:02:51 < antto> will i find it in debian? ;P~
2020-02-20T21:03:05 < Cracki> nah, you go to segger.com and click downloads
2020-02-20T21:03:13 < mawk> ozone is bad for your lungs
2020-02-20T21:03:14 < Steffanx> lunix mate.
2020-02-20T21:03:25 < mawk> calm down Steffanx 
2020-02-20T21:03:26 < Cracki> I wouldn't be surprised if they DID maintain packages in some distributions
2020-02-20T21:03:29 < mawk> don't disrespect mister torvalds
2020-02-20T21:03:30 < antto> yeah i don't want no .exe crap
2020-02-20T21:03:36 < Steffanx> fuc torvalds.
2020-02-20T21:03:41 < mawk> :(
2020-02-20T21:03:42 < Steffanx> fuck even.
2020-02-20T21:03:46 < mawk> you're going to hell
2020-02-20T21:03:56 < Steffanx> I hope so. 
2020-02-20T21:04:06 < Cracki> if you demand open sores, the dap is the way to go
2020-02-20T21:04:12 < antto> yeah
2020-02-20T21:04:13 < Steffanx> From there I will make sure you'll only get php jobs mawk
2020-02-20T21:04:31 < antto> well, the thing is, segger is muchos $$$$
2020-02-20T21:04:35 < antto> so f*ck that
2020-02-20T21:04:45 < Cracki> you spend 33 bucks on fedex
2020-02-20T21:04:53 < Cracki> for wares that are almost half that
2020-02-20T21:05:32 < Cracki> granted, shipping to your place seems to be "discouraged"
2020-02-20T21:05:34 < antto> there are some cheap seggerz but they tell u "license, blah bloh, bluhbluh, ur too ghetto, die or get rich and give us half your moniez"
2020-02-20T21:05:34 < mawk> muchos caro
2020-02-20T21:05:57 < Steffanx> Hows the php job going mawk
2020-02-20T21:06:15 < mawk> lol
2020-02-20T21:06:16 < antto> wot woz it called, jlink EDU or some such
2020-02-20T21:06:17 < mawk> not doing php anymore
2020-02-20T21:06:21 < mawk> I'm doing radar now Steffanx 
2020-02-20T21:06:27 < mawk> so embedded C like I like
2020-02-20T21:06:31 < Steffanx> hm
2020-02-20T21:06:46 < Cracki> I think the cheapest and second cheapest segger are double digit price. you can get a china clone if you want to "test" it before you buy it ;)
2020-02-20T21:07:24 < Cracki> double digit official price, aliex is 6 bucks for a bottom-of-the-line device, as shown
2020-02-20T21:07:47 < antto> i'd either pay about 30 euro shipping for that, or wait a pile of more time with free shipping
2020-02-20T21:08:18 < Cracki> only reason I haven't bought this stuff officially is because I can't honestly call my use "commercial".
2020-02-20T21:08:33 < antto> i don't know how to call my use either
2020-02-20T21:08:39 < Cracki> isn't there like... 5 bucks shipping with moderate wait?
2020-02-20T21:08:48 < antto> thus i didn't go for a jlink EDU from mouser
2020-02-20T21:09:30 < antto> cheap shipping from "UK" to here took 1 month
2020-02-20T21:09:43 < Cracki> because they really shat it from china
2020-02-20T21:09:45 < antto> from china i get stuff for usually 1 month
2020-02-20T21:09:52 < antto> probably
2020-02-20T21:10:03 < antto> it looks like it came from china visually
2020-02-20T21:10:16 < antto> the listing looked chinese as f*gg
2020-02-20T21:10:37 < antto> royal mail
2020-02-20T21:10:44 < Cracki> i've gotta try segger's embedded studio. if it's anything like ozone, will never look back
2020-02-20T21:11:31 < antto> i'm staying away from them
2020-02-20T21:12:00 < Cracki> every time I read "kinetis" somewhere, I get vietnam flashbacks
2020-02-20T21:12:02 < antto> untill i get filthy rich
2020-02-20T21:12:18 < Cracki> or until someone else can buy/pay this for you
2020-02-20T21:12:36 < antto> it ain't gon happen
2020-02-20T21:12:51 < Cracki> with that attitude it certainly won't ;)
2020-02-20T21:13:24 < antto> well, not any time soon at least
2020-02-20T21:13:39 < antto> by the time i get rich evenchually, there will be hovering cars and sh*t

2020-02-20T21:15:40 < antto> which courrier?
2020-02-20T21:15:55 < Cracki> no clue, cheapest option for that thing from china to germoney

2020-02-20T21:16:34 < Cracki> china post it said

2020-02-20T21:16:55 < Cracki> took 35 days still

2020-02-20T21:17:20 < Cracki> sat for 2-3 weeks between china and frankfurt customs shed
2020-02-20T21:17:31 < Cracki> dunno. this is the usual time
2020-02-20T21:17:33 < antto> ah, f*cking customs

2020-02-21T00:22:27 < invzim> so I want to use a DAC to control rail voltages from 3 bucks, but eh, whatabout startup/reset conditions - anyone got experience?
2020-02-21T00:22:42 < invzim> do I need an 'out-of-band' rail to control everything?
2020-02-21T00:23:04 < aandrew> invzim: usually what you do is use a pulldown/pullup (depending on the reg) to keep it turned off until your MCU is set up and ready
2020-02-21T00:23:21 < invzim> yeah, but I need to power the MCU too :)
2020-02-21T00:23:51 < aandrew> invzim: sure, but you use a dedicated LDO which you can then supplement once the main rail comes up
2020-02-21T00:24:12 < invzim> butbut, my VIN is 20V :)
2020-02-21T00:24:20 < aandrew> invzim: doesn't matter

2020-02-21T00:24:55 < invzim> not sure I follow, 20V->LDO 3V3, then disable LDO once buck is up?
2020-02-21T00:24:58 < aandrew> tiny (MCU only) reg is small. once the MCU is ready it powers on the main reg and is powered off that
2020-02-21T00:25:01 < aandrew> yeah something like that
2020-02-21T00:25:08 < aandrew> doesn't have to be LDO of course
2020-02-21T00:25:26 < invzim> the complexity of this thing is expanding fast :)
2020-02-21T00:26:38 < aandrew> generally when you talk about variable power supplies things tend to get complicated faster than with static supplies

2020-02-21T00:29:56 < aandrew> now you're racing to see who comes up first
2020-02-21T00:30:41 < invzim> maybe an output fet
2020-02-21T00:30:53 < invzim> i.e. 'true' powergood
2020-02-21T00:34:17 < invzim> hm, I havew a 12V rail that is not going to be adjustable - think the simplest would be to stuff an LDO on there and be a little watchful on how much I draw
2020-02-21T00:34:26 < invzim> sorry for talking out loud :)
2020-02-21T00:44:26 < aandrew> yes, you can have a light "always on" 3.3V fr the mcu, but you want to have your main 3.3v adjustable too? 
2020-02-21T00:45:45 < invzim> it's a USB-PD thingie, adjustable 3.3V & 5V0, fixed 12V
2020-02-21T00:45:59 < invzim> fixed -5V, but that's another chapter
2020-02-21T00:46:06 < aandrew> ok but your mcu is on a 3.3v rail; is that rail adjustable?
2020-02-21T00:46:22 < karlp> Steffanx: heh, I just guessed aachen, didn't look them up at all
2020-02-21T00:46:24 < invzim> I plan on having the MCU on 3v3 yes
2020-02-21T00:46:34 < invzim> but possibly not the output 3v3 rail

2020-02-21T01:10:06 < karlp> I like lcsc's pricing differences on "green" vs "lead free"  (and what the hell is that anyway?)

2020-02-21T01:13:45 < karlp> _and_ it needs an external diode?

2020-02-21T01:56:28 < emeb> No real "acceleration" per se. There are some DMA bitblt operations available with that Chrom ART thing, but nothing high-level.
2020-02-21T01:57:46 < aandrew> that was my understanding as well
2020-02-21T01:57:49 < aandrew> 2D DMA

2020-02-21T01:58:06 < aandrew> so acceleration as in "we'll move bits for you" but that's about it
2020-02-21T01:58:25 < ds2> but the same guy insisted full data is also available for  using the CSI interface for cameras
2020-02-21T01:58:41 < ds2> this would explain why I couldn't find anything on st's site :(

2020-02-21T02:08:29 < emeb> All I can figure is that they intend you to use on-chip flash for a bootloader and then use  QSPI flash for actual application code.

2020-02-21T06:01:32 < doomba> i'm surprised someone who has the time to point this shit out on the internet knows how to properly use painters masks
2020-02-21T06:03:45 < Cracki> "pinch the metal strip" has been said in tons of MSM. redditors are perfectly capable of taking instructions and and executing them
2020-02-21T06:04:07 < Cracki> pinch the strip and strip goes up*
2020-02-21T06:04:18 < machinehum> Wait you pinch that thing?
2020-02-21T06:04:20 < machinehum> wtf
2020-02-21T06:04:35 < Cracki> yes, also prevents fogging of the glasses, if you wear any
2020-02-21T06:05:29 < Cracki> for people with huge noses this is very important, for asians not so much
2020-02-21T06:05:58 < Cracki> it needs to "seal" against your skin or else air can enter unfiltered around the mask
2020-02-21T06:07:58 < machinehum> I have a big nose
2020-02-21T06:08:57 < Cracki> do you have calipers handy
2020-02-21T06:12:22 < Cracki> saw some asian recently, he could tuck half of his face into the collar of his jacket, including nose, with no trouble, it was that flat. very trustworthy people.
2020-02-21T06:13:07 < machinehum> I mean they don't make asian fit sunglasses for nothing

2020-02-21T06:14:29 < Cracki> I'm neither asian nor what brits call asian, how would I ever find out
2020-02-21T06:14:32 < machinehum> "Asian fit is a controversial term used by the eyewear industry to describe glasses that are made for those with lower nose bridges and higher cheekbones."
2020-02-21T06:14:45 < jadew> I just learned that I was putting it backwards, but I knew how to put it on :P
2020-02-21T06:14:48 < machinehum> There's nothing controversial about that
2020-02-21T06:15:35 < Cracki> backwards meaning inside out? I still have no idea which side is in. I think the side with the little quarter high flap goes inside?
2020-02-21T06:15:51 < jadew> Cracki, the blue part should be out
2020-02-21T06:15:57 < jadew> apparently the white part is where the filter is
2020-02-21T06:16:00 < Cracki> everything and everyone that recognizes race is "controversial"
2020-02-21T06:16:03 < jadew> I was wearing them with the white part out
2020-02-21T06:16:10 < Cracki> ic ic
2020-02-21T06:16:24 < Cracki> yes, one side has some funneling action that conducts moisture to the outside
2020-02-21T06:16:33 < jadew> but they're not effective at blocking things coming in, so it doesn't matter anyway
2020-02-21T06:17:09 < Cracki> last time I had to wear those masks I looked at the box and I don't remember that the fucking box explained this. must have been super value packs for pr0s
2020-02-21T06:17:19 < jadew> if nCoV comes to town, I'll just wear a dust mask and protective glasses
2020-02-21T06:17:53 < Cracki> yeh those masks only prevent you from coughing larger chunks of your lung at someone
2020-02-21T06:18:00 < jadew> yeah

2020-02-21T14:33:49 < aandrew> with ST's you probably used a condom-covered stick

2020-02-21T14:59:51 < Steffanx> I drive 2x38km. Which is an hour every day. Driving is such waste of time 
2020-02-21T15:01:20 < jpa-> i have to climb 15 steps every morning to get to work
2020-02-21T15:02:15 < englishman> even when I had my own biz, I found working at home doesn't work for me, I just ended up playing with cats
2020-02-21T15:02:47 < karlp> jpa-: joined walls, no idea sorry, outside being boxy/simple would be more common in the suburbs more, this is an old downtown area,
2020-02-21T15:03:08 < karlp> Thorn: three appartments from the front stairwell, two around the back, 5 in teh building itself.
2020-02-21T15:03:24 < karlp> the "ground" floor windows are actualyl storage in the basement
2020-02-21T15:04:50 < karlp> aandrew: not even moving postcode :) https://www.google.com/maps/dir/R%C3%A1nargata+45,+101+Reykjav%C3%ADk/Lj%C3%B3svallagata+30,+Reykjav%C3%ADk/@64.1441491,-21.9497475,14.25z/data=!4m14!4m13!1m5!1m1!1s0x48d60b2bfe280585:0x60886f0ef9a7c52d!2m2!1d-21.9515391!2d64.1505444!1m5!1m1!1s0x48d60b2e2862cab7:0x5c88f53c2dd45176!2m2!1d-21.95023!2d64.1444595!3e2
2020-02-21T15:05:34 < karlp> we also have people here driving like 70-80k each way, but I thin they're fucking insane.
2020-02-21T15:06:05 < karlp> I have a ~3km bike ride.
2020-02-21T15:06:32 < PaulFertser> karlp: it's more insane to drive 20 km spending 1.5 hours like people do in Moscow.
2020-02-21T15:06:51 < karlp> definitely, no debate.
2020-02-21T15:07:04 < karlp> I like living here :)
2020-02-21T15:16:31 < jadew> that doctor that covers the coronavirus on youtube said that mathematical models are predicting that 60% of the world's population is going to get it
2020-02-21T15:16:56 < karlp> so it's like anything else, we all have it, it doesn't matter
2020-02-21T15:17:51 < jadew> except that it would result in ~100 million deaths
2020-02-21T15:18:14  * PaulFertser is so tempted to bet money against jadew 
2020-02-21T15:18:27 < jadew> well, I'm not going to bet on that
2020-02-21T15:18:39 < jadew> but it's good to keep it in mind
2020-02-21T15:18:42 < specing> "doctor"
2020-02-21T15:18:47 < specing> Is it even a real doctor?
2020-02-21T15:18:53 < jadew> specing, yeah
2020-02-21T15:18:57 < jadew> he's a teacher at a university
2020-02-21T15:19:06 < jadew> and is very reserved in his statements
2020-02-21T15:19:13 < PaulFertser> jadew: you might like https://en.wikipedia.org/wiki/New_Chronology_(Fomenko) , especially if you trust math professors
2020-02-21T15:19:36  * karlp laughs
2020-02-21T15:20:01 < PaulFertser> He was a teacher at a univeristy too
2020-02-21T15:20:10 < karlp> jadew: so, like twice the detahs of a normal year... no big deal then.
2020-02-21T15:20:35 < jpa-> englishman: for me it has its problems the other way, feels like i'm always at work
2020-02-21T15:20:40 < jpa-> englishman: maybe i should get a cat
2020-02-21T15:20:47 < jadew> PaulFertser, it's not his model tho
2020-02-21T15:21:10 < jadew> but if he believes it's possible, it's probably something to think about
2020-02-21T15:21:49 < jadew> he's not a crack pot
2020-02-21T15:21:50 < jpa-> it's certainly possible
2020-02-21T15:21:55 < karlp> it's possible that a toilet seat will fall from a plan and land on your head.
2020-02-21T15:22:08 < jpa-> i find it actually quite surprising that so many epidemies just fizzle out instead of being global
2020-02-21T15:22:27 < jadew> you guys realize that the spread of the virus outside of china is following an exponential curve, right?
2020-02-21T15:22:33 < jadew> it hasn't stopped or anything...
2020-02-21T15:22:39 < jpa-> not yet, and might not
2020-02-21T15:22:51 < jpa-> but the real epidemic will be next influenza season, if at all
2020-02-21T15:23:10 < jadew> jpa-, it seems this is much more virulent than influenza
2020-02-21T15:23:39 < englishman> I hope jadew gets coronavirus 100,000,000 times
2020-02-21T15:24:00 < specing> jadew wouldn't care, they are not 80 years old
2020-02-21T15:24:21 < jadew> yeah... the death rate in our age group is 0.2%
2020-02-21T15:24:32 < jadew> it only gets higher after 50 yo
2020-02-21T15:24:59 < specing> has anyone healthy 20-50 year old actually died from it?
2020-02-21T15:25:04 < jadew> and I'm in Romania, we don't have as much chinese as CA
2020-02-21T15:25:21 < jadew> specing, clearly, otherwise it would be 0 :)
2020-02-21T15:25:47 < jadew> the guy who died in Europe was 18 yo
2020-02-21T15:25:50 < specing> jadew: but were the 0.2% actually healthy?
2020-02-21T15:26:04 < jadew> I don't know
2020-02-21T15:26:11 < specing> pollution weakens your immune system
2020-02-21T15:26:21 < specing> so chinese 20-50 dying is meaningless
2020-02-21T15:27:14 < specing> I think the coronavirus sucks and they can bring it on
2020-02-21T15:27:31 < kakimir> flying SARS-AIDS Dengue-fever
2020-02-21T15:27:33 < specing> it can kiss my healthy long distance bicyclist butt

2020-02-21T15:39:27 < kakimir> good health generally works in favour but it's just moves you in health axis while probability axis still remain non-zero
2020-02-21T15:41:15 < PaulFertser> With certain diseases good health (and hence better immune reaction) can make matters worse, similar to how autoimmune problems evolve.
2020-02-21T15:41:35 < PaulFertser> IIRC it was kinda the case with some of the recent flus.
2020-02-21T15:43:18 < Thorn> karlp: ok I see, congrats

2020-02-21T15:54:29 < jadew> PaulFertser, how does that works?
2020-02-21T15:54:39 < jadew> too strong of a reaction?

2020-02-21T16:11:29 < PaulFertser> Most probably written by an intelligent native speaker.
2020-02-21T16:12:18 < jadew> most asians I've interacted with lately had good english
2020-02-21T16:14:15 < kakimir> usually you speak mandarin with them?
2020-02-21T16:14:20 < kakimir> or katonise
2020-02-21T16:14:26 < jadew> no, chinglish
2020-02-21T16:14:35 < kakimir> sign language
2020-02-21T16:15:14 < PaulFertser> This letter is probably written by somebody fluent in writing texts, journalist-level skills I'd say.
2020-02-21T16:15:55 < PaulFertser> Let's wait for aandrew to read and and give his judgement.

2020-02-21T16:24:58 < jadew> PaulFertser, fiverr indian
2020-02-21T16:25:26 < karlp> PaulFertser: it's not that good actualy :)
2020-02-21T16:25:39 < karlp> they're solid, but idioms are always problematic.
2020-02-21T16:25:56 < PaulFertser> karlp: please elaborate
2020-02-21T16:26:07 < karlp> "pulling out the stocks" is completely bogus, it's "pulling out the stops"
2020-02-21T16:26:21 < PaulFertser> typo probably
2020-02-21T16:26:29 < karlp> and you'd normally talk of brushing or sweeping out cobwebs, not wiping them.
2020-02-21T16:26:32 < PaulFertser> Because stocks doesn't make sense there
2020-02-21T16:26:44 < karlp> it might if you'd only heard it as a phrase.
2020-02-21T16:26:52 < karlp> and that's j ust in the first paragraph
2020-02-21T16:26:54 < PaulFertser> Hm, indeed
2020-02-21T16:27:24 < karlp> but yes, they do generally have good written texts,

2020-02-21T16:27:52 < karlp> they've been dealing with westerners for a long time now, they know what helps
2020-02-21T16:28:22 < karlp> clearing the cobwebs is probably even more common
2020-02-21T16:28:29 < kakimir> aah.. seed studio.. didn't you expect seed studio to have people that can write flawless english?
2020-02-21T16:28:52 < Steffanx> Seeed is cleaned from corona. Better start the orders
2020-02-21T16:28:53 < karlp> like, if you search for idiom wipe cobwebs, you'ðll not get a single wipe in the results.
2020-02-21T16:29:11 < kakimir> PaulFertser: latex is a mess

2020-02-21T16:29:36 < kakimir> liquid latex
2020-02-21T16:29:48 < karlp> yes, and I can find an example in a seeed mailout too :)
2020-02-21T16:29:55 < karlp> doesn't mean it's a good or normal usage :)
2020-02-21T16:30:54 < PaulFertser> https://www.google.com/search?hl=en&q=%22wipe%20off%20the%20cobwebs%22 plenty of hits, not sure how legit
2020-02-21T16:31:15 < karlp> only 43k though, so ~wrong.

2020-02-21T16:32:22 < doomba> the google.com link
2020-02-21T16:32:44 < doomba> it's in my dns blacklist as a malicious site
2020-02-21T16:32:53 < PaulFertser> doomba: what do you think about the language in http://paste.debian.net/1131401/ ?
2020-02-21T16:33:02 < doomba> what about it?
2020-02-21T16:33:02 < karlp> ok, good to know, you don't ever need to tell us again that you can't open those links.
2020-02-21T16:33:05 < doomba> i read it
2020-02-21T16:33:36 < doomba> seeed paid a transient $10 to write a heartfelt letter?
2020-02-21T16:33:40 < PaulFertser> doomba: do you think it's more likely to have been written by a native speaker or a foreigner?
2020-02-21T16:34:02 < doomba> it's written by either an american or a european.
2020-02-21T16:34:54 < doomba> possibly canadian
2020-02-21T16:35:14 < doomba> it seems too proper to be american ennglish
2020-02-21T16:35:49 < doomba> i'm unable to spot any obvious indicators of which english dialect this is
2020-02-21T16:36:24 < doomba> i do think it is a native english speaker though - just not sure from which country. (english was the writer's first language for sure)
2020-02-21T16:37:44 < doomba> if were to take a wild guess, i'd say this resembles how people talk in BC Canada
2020-02-21T16:38:57 < kakimir> you think chinese companies don't have non-chinese employees?
2020-02-21T16:39:26 < Steffanx> Should ask Ultrasauce he's our english expert 
2020-02-21T16:41:57 < BrainDamage> yeah, they just paid someone to write a PR letter, maybe they hired themm

2020-02-21T16:45:47 < karlp> we're having "words" here about whether MPs should have to wear shoes or not in parliament :)
2020-02-21T16:45:52 < karlp> who needs racism!

2020-02-21T16:51:31 < invzim> in my book, TI=bad, st=ok, analog=great
2020-02-21T16:53:05 < kakimir> analog when the bom cost is not the main issue
2020-02-21T16:53:30 < kakimir> or when you have no choice
2020-02-21T16:54:12 < kakimir> st doesn't seem to be a big player in regulators
2020-02-21T16:54:32 < invzim> I know, just to give you my scale of "any good" :)
2020-02-21T16:54:50 < kakimir> TI has some niche stuff and micro/nanopower stuff
2020-02-21T16:55:24 < invzim> my main grief with TI is that their datasheets seems to be written by interns and errata/odd stuff with their parts (in general)
2020-02-21T16:56:30 < doomba> LOL
2020-02-21T16:56:36 < doomba> @ that yt vid englishman 
2020-02-21T16:57:04 < karlp> invzim: how do you get "bad" or "good" for a single vendor just like that?
2020-02-21T16:57:19 < karlp> for their whole product lines?
2020-02-21T16:57:28 < invzim> personal subjective impression :)
2020-02-21T16:57:29 < jpa-> well clearly all TI parts are designed by the same dude
2020-02-21T16:58:41 < kakimir> that guy has worked his ass off
2020-02-21T17:05:31 < kakimir> what is that RAM type that can have 2 masters?
2020-02-21T17:06:04 < invzim> dual-port?
2020-02-21T17:08:56 < kakimir> hmm pricey!
2020-02-21T17:09:32 < kakimir> I take performance penalty rather
2020-02-21T17:09:50 < invzim> only used it inside an fpga
2020-02-21T17:10:22 < kakimir> by looks of those chips it's something popular in 90s
2020-02-21T17:12:46 < BrainDamage> it's useful if you want to do dsp
2020-02-21T17:13:14 < BrainDamage> circular buffers can have read and write port run at different clock rates
2020-02-21T17:14:45 < invzim> how much storage do you need?
2020-02-21T17:18:08 < PaulFertser> I once heard a chinese woman at an electronics conference (they bragged about their cloned rad-hard xilinx clones and other stuff like that) and her intonations were very closely resembling that of a text-to-speech engine, it was very bizarre to hear that live.

2020-02-21T19:20:00 < Cracki> the thought of one's own mortality makes one deny all kinds of truth
2020-02-21T19:23:25 < Cracki> offline i see it very strongly. people choose when to have hope and when to get hysterical entirely independent of facts and arguments. feelings don't care about your facts.
2020-02-21T19:32:43 < PaulFertser> Cracki: do you see some exceptions though?
2020-02-21T19:32:53 < Cracki> exceptions to what
2020-02-21T19:33:01 < Cracki> ah, that
2020-02-21T19:33:04 < Cracki> rarely
2020-02-21T19:33:21 < Cracki> some people actually think when I point out direct contradictions in their thinking
2020-02-21T19:33:21 < karlp> this is the same as your normal, "everyone's a moron except me" right? :)
2020-02-21T19:33:41 < PaulFertser> Well, most people are dumb so silly reactions are to be expected. It gets more interesting when smart people show silly reactions.
2020-02-21T19:33:50 < Cracki> I'm not saying dumb
2020-02-21T19:34:02 < PaulFertser> Well, you clearly have IQ above 100.
2020-02-21T19:34:33 < Cracki> I can empathize with people choosing to ignore the threat of a pandemic with a non-negligible death rate
2020-02-21T19:35:02 < Cracki> I'm not talking about double digits either, but about people I meet at uni
2020-02-21T19:35:20 < PaulFertser> Isn't 100 supposed to be median?
2020-02-21T19:35:26 < Cracki> people choose to "look away" so they can function
2020-02-21T19:35:33 < Cracki> defined to be the average
2020-02-21T19:35:45 < PaulFertser> I thought median, not average
2020-02-21T19:35:46 < Cracki> and 15 (or 16) points is a one standard deviation
2020-02-21T19:36:13 < Cracki> since it's pretty much a gaussian distribution, median and mean "coincide"
2020-02-21T19:36:29 < PaulFertser> Cracki: is your point that people like us should be concerned about the COVID-19 pandemic?
2020-02-21T19:37:15 < Cracki> my point is to face facts. how you act on them is up to you.
2020-02-21T19:37:47 < Cracki> not speaking to you, but abstractly: don't deny facts to justify sticking your head in the sand
2020-02-21T19:38:15 < PaulFertser> Cracki: well, I'm not worried about the pandemic, and jadew is. Who's doing the right thing?
2020-02-21T19:38:23 < Cracki> one doesn't need justification for sticking one's head in the sand

2020-02-21T19:39:05 < englishman> panicking always helps
2020-02-21T19:39:09 < emeb> these days you can pick the facts you want.
2020-02-21T19:39:13 < Cracki> "if hell is real and you don't believe, you go to hell. if hell isn't real and you believe, nothing lost."
2020-02-21T19:39:31 < Cracki> if he prepped more than you, he'd be better off
2020-02-21T19:39:45 < PaulFertser> By believing in hell you can make your life much, much worse!
2020-02-21T19:40:07 < PaulFertser> Look at those amish people or other fanatics.
2020-02-21T19:40:08 < emeb> if hell isn't real and you believe then you've wasted a lot of mental energy on bullshit.
2020-02-21T19:40:51 < Cracki> facts as I'm aware of them: official chinese numbers are far from accurate, very likely underestimates, or gaps in the data, or outright fabrication
2020-02-21T19:41:15 -!- c10ud [~c10ud@emesene/dictator/c10ud] has quit [Quit: Leaving]
2020-02-21T19:41:35 < Cracki> right, mental health is important. you can and should choose to ignore things you can do nothing about.
2020-02-21T19:41:55 < Cracki> there's little you individually can do about the spread (or not) of a disease.
2020-02-21T19:41:56 < PaulFertser> Cracki: have you read they now started to include all pneumonia cases in their statistics?
2020-02-21T19:42:07 < Cracki> confirmed or suspected
2020-02-21T19:42:12 < PaulFertser> pneumonia!
2020-02-21T19:42:27 < PaulFertser> So they might even be overestimating it now.
2020-02-21T19:42:35 < Cracki> their definition of "confirmed" changed a few times already.
2020-02-21T19:43:00 < Cracki> they admitted lung xrays as confirmation, then there was another change...
2020-02-21T19:43:41 < PaulFertser> So lung xrays are guaranteed to give a larger number than strict SARS testing.
2020-02-21T19:43:55 < Cracki> I don't see a problem with admitting pneumonia. how many would develop pneumonia at this time of year, if not for a coronavirus infection?
2020-02-21T19:44:31 < Cracki> what should make you wonder is their apparent struggle to cremate "all those bodies"
2020-02-21T19:45:35 < Cracki> just from old age there would be a steady base rate of deaths they have to handle anyway, even if a tiny fraction of those are chosen to be cremated
2020-02-21T19:46:13 < PaulFertser> Cremating is fast and reliable way of disposing contaminated material.

2020-02-21T19:46:59 < Cracki> well it's human bodies and for reasons of piety you keep the ashes separate
2020-02-21T19:47:25 < Cracki> I haven't heard of mass grave situations yet, or big piles of burning bodies
2020-02-21T19:48:34 < zyp> is there any reason to be concerned about the coronavirus unless you're planning to go to china?
2020-02-21T19:49:01 < BrainDamage> the person-person transmission rate in people in countries other than china is nearly 0
2020-02-21T19:49:08 < Cracki> I would love to know how it manages to spread so well in china/asia and if that can and will happen in the rest of the world too
2020-02-21T19:49:10 < PaulFertser> Reasons of safety should prevail reasons of piety.
2020-02-21T19:49:20 < zyp> BrainDamage, that's my understanding too
2020-02-21T19:49:26 < PaulFertser> BrainDamage: unless you count that cruise ship, heh
2020-02-21T19:49:36 < Cracki> unless someone has a reason why the rest of the world is different, I'm inclined to assume it's same
2020-02-21T19:49:39 < BrainDamage> sure, that was an isolated environment though
2020-02-21T19:49:46 < Cracki> so we're all at risk of it spreading like it spreads in china
2020-02-21T19:50:00 < BrainDamage> Cracki: it has the potential to
2020-02-21T19:50:26 < BrainDamage> however with single isolated cases, it hasn't reached yet the concerning status for personal health outside
2020-02-21T19:50:34 < Cracki> what we _can_ count on is quarantine measures finally being set up "everywhere"
2020-02-21T19:51:51 < Cracki> possibly the chinese vastly underestimated the situation and their "sudden" lockdowns were to catch up measures to reality
2020-02-21T19:52:44 < PaulFertser> I guess this very discussion shows that we all are not burying our heads in sand, otherwise we wouldn't know the details, the websites with statistics etc.
2020-02-21T19:53:33 < Cracki> if we could don the tin foil hats for a moment... I find the "eugenics" theory interesting. intentionally spread some pathogen to free society from caring for its weak and elderly
2020-02-21T19:53:59 < BrainDamage> here's an active topic of discussion, as in if you go to a pub people will actively talk about it every now and then
2020-02-21T19:54:11 < emeb> yesterday ordered some PCBs from JLCPCB - about 25% done with the fab process according to their website. Seems they're not badly impacted by this.
2020-02-21T19:54:29 < BrainDamage> I find that hypothesis kind of useless, regardless of the source you want to look how to fix it first
2020-02-21T19:54:39 < Cracki> co2 emissions dropped by 25%, public transport dropped by 80%
2020-02-21T19:54:46 < BrainDamage> once the problem is gone, then you can go conspiracy theory all you want
2020-02-21T19:54:48 < Cracki> in that province, I think were the numbers i saw
2020-02-21T19:55:11 < Cracki> "gallows humor"
2020-02-21T19:55:31 < Cracki> isn't supposed to have a purpose other than entertainment
2020-02-21T19:56:02 < PaulFertser> BrainDamage: people in pub are likely to have no real clue and discuss it just for the sake of discussing.
2020-02-21T19:56:18 < Cracki> they get the same information we do, don't they?
2020-02-21T19:56:46 < Cracki> what distinguishes us from a pub?
2020-02-21T19:56:55 < zyp> people on irc are likely to have no real clue and discuss it just for the sake of discussing
2020-02-21T19:57:01 < Cracki> :)
2020-02-21T19:57:06 < PaulFertser> No, most of the people do not dig, and many can not properly process written text.
2020-02-21T19:57:15 < Cracki> consume tv, yes
2020-02-21T19:57:51 < Cracki> stare intently at newspaper if you want to look sophisticated
2020-02-21T19:57:51 < PaulFertser> Cracki: well, go to a (ordinary) pub and ask how many people can properly tell mean from median :)
2020-02-21T19:58:14 < Cracki> that's just one order of magnitude of difference on the IQ
2020-02-21T19:58:33 < PaulFertser> So even if we were reading the same text we might be getting different impressions from it. Because of background.
2020-02-21T19:58:36 < Cracki> btw, I recently looked at industrial image processing job openings...
2020-02-21T19:58:58 < Cracki> they talked about a gaussian lowpass and they called it "binomial filter"
2020-02-21T19:59:50 < Cracki> I became aware that lingo in differing "fields", for the same concept, can be opaque or surprising
2020-02-21T20:00:30 < PaulFertser> Interesting
2020-02-21T20:00:36 < Cracki> they called it binomial because they rightly identified it as a discretely sampled situation, but in the limit it's still a normal distribution
2020-02-21T20:01:00 < Cracki> I know "bilateral filter" is a complex operation, more complex than plain convolution
2020-02-21T20:01:55 < Cracki> so I thought, what's this, must be fancy... turns out it's just "grade school math" dressed up

2020-02-21T21:11:44 < antto> so the ebay guy replied
2020-02-21T21:12:06 < antto> "’m really sorry that I disappointed you. Here, I sincerely apologize to you. I will refund you, can you not leave a bad comment ?because it is important to us,and hope you can understanding.have a nice day! looking forward to your reply."
2020-02-21T21:13:22 < antto> he did not answer my original question tho, i asked if he put the wrong thing in the bag or if it's a scam
2020-02-21T21:13:56 < doomba> Someone may ask whether our machine can support 1.2 meter LED strip. Of course, the answer is yes.
2020-02-21T21:14:06 < Cracki> heh, he just wants to prevent his 4.9 stars from dropping to 4.8
2020-02-21T21:14:17 < antto> by his reply, it smells like "okay, u caught me, imma return ur money just don't give me negative feedback so i can keep scamming otherz"
2020-02-21T21:14:39 < Cracki> nah, they'll eat any troubles so long as they can keep their 4.9 stars
2020-02-21T21:15:09 < antto> he doesn't want me to return it back, he doesn't offer to send me the "right" item
2020-02-21T21:15:15 < antto> smells like scam
2020-02-21T21:15:17 < antto> right?
2020-02-21T21:15:28 < Cracki> competition is fierce. people sort by price, by seller rating, ... and if you're one cent or one tenth worse than competition, you sell nada
2020-02-21T21:15:46 < Cracki> nobody ever returns stuff to china, that costs us too much
2020-02-21T21:15:54 < antto> right
2020-02-21T21:15:55 < Cracki> us being rest of the world
2020-02-21T21:16:18 < antto> yeah, with things that cost a fraction of their shipping..
2020-02-21T21:16:54 < Cracki> eh, try one more time to ask for a "proper" stlinkv2 and if he doesn't understand, take the refund?
2020-02-21T21:17:21 < Cracki> I think I looked into returning something to china once. it was more than 10 bucks.
2020-02-21T21:17:32 < antto> yeah i was expecting he'd propose to send the right thing this time or something
2020-02-21T21:17:46 < Cracki> he might not understand. this is all through auto translation
2020-02-21T21:18:00 < Cracki> or he honestly has no idea what he's selling
2020-02-21T21:18:35 < Cracki> they're traders. they buy and sell, they don't need to know what it does.
2020-02-21T21:18:56 < antto> if he doesn't have an idea wut he sells (which i can perfectly imagine) then i'd rather tell him to fix his description and give me my moneiz
2020-02-21T21:19:22 < Cracki> a few factories make the stuff, then it goes into big potato sacks and drops on markets
2020-02-21T21:19:37 < antto> i could even write a description for him, in less broken engrish
2020-02-21T21:19:44 < Cracki> :P
2020-02-21T21:20:28 < Cracki> I still have no idea what the thing he sent you does. looks like ttl uart adapter?
2020-02-21T21:20:38 < antto> yes
2020-02-21T21:20:46 < Cracki> does it actually do that?
2020-02-21T21:21:11 < antto> i didn't test it, but TX pin shows 3.3V, RX pin shows 5-ish which i guess is via a pull resistor
2020-02-21T21:21:23 < antto> and there are pins with 3.3 and 5V for convenience
2020-02-21T21:21:46 < antto> lsusb says: "QinHeng Electronics HL-340 USB-Serial adapter"
2020-02-21T21:21:56 < Cracki> then it must be that
2020-02-21T21:22:19 < antto> the labels on the alu body also agree with that
2020-02-21T21:22:26 < Cracki> I wodner if that thing can do gpio duty or if it's just uart
2020-02-21T21:23:05 < Cracki> I think I had a datasheet for it on screen but fuck me if I remember what it said
2020-02-21T21:23:22 < antto> "STC" "Auto  Programmer" <- this is probably misleading but meh, "USB-TTL", and then there is a pinout legend which is probably accurate.. it shows GND RXD TXD 5V 3.3V TCK RST and a few N.C. pins
2020-02-21T21:24:32 < antto> Cracki i was told that for SWD one of the data pins should be bidirectional
2020-02-21T21:24:38 < Cracki> yes
2020-02-21T21:24:40 < antto> at minimum
2020-02-21T21:24:51 < Cracki> st's reference stlink circuitry uses two pins tied together for this
2020-02-21T21:24:57 < Cracki> with resistors
2020-02-21T21:25:37 < antto> Cracki but IMO if you have to buy this device described as "SWD programmer" and then put external resistors to tie two pins together - dafuq is this?
2020-02-21T21:25:40 < Cracki> so if you had something that can do gpio, and you have a breadboard, and the firmware/software to make it to the right thing, that's how it can work
2020-02-21T21:25:45 < Cracki> right
2020-02-21T21:26:11 < Cracki> it's likely just a uart, can't sell that as a stlink
2020-02-21T21:26:42 < antto> i could then make a parallel port breakout board thing and call it "video card" .. because if you put enough circuitry behind it and write a speshul program you might be able to drive some VGA monitor
2020-02-21T21:27:05 < Cracki> ;)
2020-02-21T21:27:28 < antto> or a bag of sand and call it "cortex M7 with potentially gigabytes of RAM"
2020-02-21T21:27:31 < Cracki> I'm sure people did that

2020-02-21T21:31:39 < Steffanx> I didnt do that yet. I'm slow :P
2020-02-21T21:31:52 < antto> wow, shipping via teleportation?

2020-02-21T21:34:19 < antto> are there waffles with bacon?
2020-02-21T21:34:24 < antto> for muh cat
2020-02-21T21:39:03 < Steffanx> my fake company is called waffle.express for a reason antto :P
2020-02-21T21:40:07 < kakimir> send me waffles is a code for an assasin
2020-02-21T21:40:24 < kakimir> then you give targets name and address
2020-02-21T21:41:07 < kakimir> waffles delivered is a code for job done
2020-02-21T21:41:18 < Steffanx> i got an address in finland, hm
2020-02-21T21:53:27 < karlp> PaulFertser: I find your disparagements of the intellect level of people in a pub to be most displeasing.
2020-02-21T21:55:30 < PaulFertser> karlp: I admit I do not visit pubs often so certainly not enough data for proper statistics.
2020-02-21T21:55:54 < PaulFertser> karlp: so I treated "people in a pub" in a "general population" meaning.
2020-02-21T21:56:03 < PaulFertser> karlp: please correct me where I'm wrong.
2020-02-21T21:56:27 < Steffanx> perhaps you visiting a pub would lower the average or median(whatever you like most) IQ by quiet a few points PaulFertser. 
2020-02-21T21:57:36 < karlp> Cracki: what are you talking about st's stlink reference using two pins tied together with resistors?! where do you get that from?
2020-02-21T21:58:02 < karlp> Cracki: a common method to get an ft2232 device to do swd, instead of the jtag they normally do, is to use two pins, but that's far from the "st reference impelmentation of stlink"
2020-02-21T21:59:08 < jpa-> it sounds like just what is in every discovery etc. board schematics?
2020-02-21T21:59:25 < PaulFertser> karlp: I guess an average icelander is smarter than an average russian.
2020-02-21T22:00:24 < PaulFertser> jpa-: disco boards have SWDIO connected to a single stlink pin, no resistor hacks needed afaict. 
2020-02-21T22:00:33 < jpa-> though it seems to me that stlink on discovery board just uses a single pin, yeah

2020-02-22T02:18:09 < jadew``> what's the situation like in there?
2020-02-22T02:18:53 < BrainDamage> ~50km away from me

2020-02-22T02:18:59 < jadew``> damn...
2020-02-22T02:19:08 < jadew``> are you taking any measures?
2020-02-22T02:19:42 < BrainDamage> no, not yet
2020-02-22T02:20:13 < Steffanx> Lol jadew``

2020-02-22T02:20:50 < BrainDamage> altough some people are more concerned about this milan's fashion week
2020-02-22T02:21:02 < BrainDamage> where there's going to be a lot of foreign visits
2020-02-22T02:21:08 < qyx> uh 17 new cases
2020-02-22T02:21:49 < Steffanx> Yet again. The man that died was old and had a bad health already.
2020-02-22T02:22:03 < jadew``> Steffanx, yeah, that's not the point
2020-02-22T02:22:09 < jadew``> the point is that it seems to be loose
2020-02-22T02:22:23 < Steffanx> Or not.
2020-02-22T02:22:25 < jadew``> the detection ratio is expected to be at most 25% in the EU
2020-02-22T02:22:42 < jadew``> which means there are at least 80 people infected, 60 of which nobody knows yet in thre
2020-02-22T02:22:44 < jadew``> there
2020-02-22T02:23:06 < BrainDamage> I'll be concerned once it starts getting in the 4-5 digits
2020-02-22T02:23:34 < Steffanx> Will you? Just to for a self-quarantine
2020-02-22T02:24:00 < BrainDamage> as in I'll avoid crowded bars
2020-02-22T02:24:08 < BrainDamage> not that I'll live as shut in
2020-02-22T02:27:00 < BrainDamage> even if I caught it, 2% mortality means 1/50 chance to die, quite low, but the perspective of two weeks of pneumonia isn't appealing

2020-02-22T12:20:26 < Cracki> TWO PINS. take note of SWDIO/TMS/JTMS, PB12+PB14. I doubt it's because "jtag and swd are different". it's because you have to listen on and drive that line simultaenously. lhttp://luyao-han.online/diy-stlinkv2-debugger/
2020-02-22T12:21:30 < Cracki> can't be assed to call up official docs, diy

2020-02-22T12:31:08 < Cracki> my speculation may be wrong but that schematic can't be denied
2020-02-22T12:32:03 < Cracki> maybe it's because one mode can use pushpull and the other is open-drain but needs 100 ohm instead of the default built in pullup
2020-02-22T12:45:08 < dongs> what
2020-02-22T12:45:47 < dongs> SWD*IO* is swithching input/output, so they prolly havce 2 timers setup one doing input capture one doing output compare
2020-02-22T12:45:49 < antto> o hai therr senpai
2020-02-22T12:45:58 < dongs> and to avoid tearing down on each direction cahnge they just use different pins for it
2020-02-22T12:46:23 < dongs> and when in jtag mode they're only using TMS pin and IO one is floating
2020-02-22T12:47:34 < antto> i'd like to know if cmsis-dap/DAPlink is "dongs approved"
2020-02-22T12:47:44 < dongs> no that shit is aids
2020-02-22T12:47:49 < antto> :~(

2020-02-22T12:49:27 < antto> oh well
2020-02-22T12:49:49 < antto> i hope it's better than nothing ;P~

2020-02-22T12:52:05 < Cracki> PB14: SPI2_MISO/ USART3_RTS (8) TIM1_CH2N (8)
2020-02-22T12:52:49 < Cracki> antto, weren't you having trouble with stlink3 because it only supports ST chips?
2020-02-22T12:53:07 < antto> (yes)
2020-02-22T12:53:16 < antto> but i wonder what senpai thinks about it
2020-02-22T12:53:21 < Cracki> ah, you are asking for his approval
2020-02-22T12:53:54 < antto> the holy dongs certificate
2020-02-22T12:56:49 < antto> it was very cheap (for an official legit programmer), but i can't decide whether to try to sell it
2020-02-22T12:57:21 < antto> shipping to around europe might end up as much as the programmer's price
2020-02-22T12:58:45 < Cracki> keep it. maybe segger comes up with a jlink OB firmware for it
2020-02-22T12:59:26 < Cracki> I'm sure they will, new discos will have v3 circuitry and it's in their interest to get people into experiencing segger
2020-02-22T12:59:29 < antto> i'm curious bout what senpai thinks about muh decision to put STDC14 connector on my board.. and about the STDC14 itself
2020-02-22T13:00:01 < antto> mmm, EGGsperiencing sEGGer
2020-02-22T13:01:01 < Cracki> I think it's a suboptimal decision. plugging a 10-pin cable (cortex m standard) on that will be tricky because they're a little wide on the ends and there are pins that'll interfere.  "stdc14" is ST's invention so I wonder if anyone else will adapt to it.
2020-02-22T13:01:23 < Cracki> easter spirit year-round
2020-02-22T13:02:00 < antto> luckily i intentionally didn't put an actual IDC socket, i put bare headers
2020-02-22T13:02:13 < antto> so i can cut the outter ones
2020-02-22T13:02:28 < antto> but i'm thinking to try and keep them
2020-02-22T13:02:36 < Cracki> I'd recommend keeping those pins and making a special cable instead
2020-02-22T13:03:04 < Cracki> the rx/tx, if you have it hooked up, can be useful
2020-02-22T13:03:34 < antto> i think i got a 1.27mm pitch doublerow pin socket strip, i'll cut a 2x5 chunk from it and i'll try to make an adapter with it
2020-02-22T13:03:41 < antto> gonna be ghetto and difficult tho
2020-02-22T13:04:24 < Cracki> yeah or just rip the pins out and stick 2x5 pins into the 2x7 footprint :>

2020-02-22T16:18:26 < jpa-> for the "3838" in the answer, i'd start thinking about "3600" and guess 60, which would be kinda like the first step, but after that i'd just iterate by random steps

2020-02-22T16:29:32 < mawk> instead of (1, X, X², …) you use the Chebyshev polynomials
2020-02-22T16:29:53 < mawk> you can prove they are the best using some topology arguments
2020-02-22T16:30:06 < mawk> then you get a dramatical increase in convergence

2020-02-22T16:31:07 < BrainDamage> mawk: if I am calculating sqrt on paper, it's assuming I have no access to a pc, math book, etc

2020-02-22T19:29:55 < aandrew> I was surprised. chicken bbq sauce and broccoli which sounds awful but isn't
2020-02-22T19:30:10 < aandrew> 99% of the time my pizza is pepperoni, mushroom and bacon. 1% it's got everything on it

2020-02-22T19:32:50 < Cracki> I'm ok with lots of meat on top but it needs to remain handy and that doesn't sound handy
2020-02-22T19:33:08 < BrainDamage> no garlic sauce
2020-02-22T19:33:27 < BrainDamage> yes, it's a bit awkward, as in some pieces may fall off on small slices
2020-02-22T19:33:29 < Steffanx> Here it comes with that as well

2020-02-22T19:34:08 < Cracki> just fold the pizza in half to keep stuff in, that's almost a kebab
2020-02-22T19:34:21 < BrainDamage> that's a calzone

2020-02-22T19:34:50 < Cracki> some do that per slice, fold it along the radius. gives it stiffness and keeps the fingers cleaner
2020-02-22T19:35:05 < BrainDamage> yes, that's common, you bend in a V/U shape
2020-02-22T19:35:12 < Cracki> french fries on pizza hmmm I've seen pasta on pizza
2020-02-22T19:35:20 < BrainDamage> you don't have to fold all the way, just the crease is sufficient

2020-02-22T19:37:27 < Steffanx> in pizza32 BrainDamage is king.
2020-02-22T19:37:55 < Cracki> normal fries, ok fairly consistent temp, but those potato wedges are almost room temp on the outside but steaming at the core
2020-02-22T19:38:45 < Steffanx> meh. salty anchovy is the worst of it all
2020-02-22T19:39:05 < Cracki> much cheese much good
2020-02-22T19:39:57 < Cracki> yes, one (cartwheel) is enough
2020-02-22T19:41:27 <@BrainDamage> huh, that's a real napolitalian style pizza, I'm impressed by google
2020-02-22T19:42:32 < Cracki> what do you italians do with that thick rim on pizza like that
2020-02-22T19:42:53 < Steffanx> the what boddax?
2020-02-22T19:42:53 <@BrainDamage> it's more like the style in naples
2020-02-22T19:43:00 < jadew``> BrainDamage, what do you know about the new cov cases?
2020-02-22T19:43:11 < jadew``> looks like you have 25 more, since yesterday

2020-02-22T19:43:40 < jadew``> I just joined, I'll check the log
2020-02-22T19:43:40 < jadew``> thanks
2020-02-22T19:43:44 < Cracki> is that rim a little crunchy but overall edible, or do people around me just kill bake it too long until the rim is like granite
2020-02-22T19:43:56 < BrainDamage> jadew``: about 2h ago
2020-02-22T19:44:10 < BrainDamage> no, it's very soft with that style
2020-02-22T19:44:13 < BrainDamage> very spongy
2020-02-22T19:44:16 < Cracki> nice
2020-02-22T19:44:36 < BrainDamage> here the harder the crust the thinner it gets
2020-02-22T19:44:52 < BrainDamage> the very hard crusts happens only on take away style pizzas
2020-02-22T19:45:35 < BrainDamage> generally, the same amount of dough is always used
2020-02-22T19:45:45 < BrainDamage> so if the rim is thick the mid is thin, and viceversa
2020-02-22T19:45:59 < BrainDamage> take away pizzas are very thick, almost like a focaccia
2020-02-22T19:47:08 < BrainDamage> like this https://media-cdn.tripadvisor.com/media/photo-s/05/9a/7c/f6/alla-toscanapizza-al.jpg

2020-02-22T19:47:21 < BrainDamage> you only eat a single slice of those
2020-02-22T19:47:22 < Steffanx> thats awful
2020-02-22T19:47:27 < BrainDamage> because it's a caloric bomb
2020-02-22T19:47:35 < BrainDamage> it's our version of fast food
2020-02-22T19:48:18 < Cracki> so the opposite of fast food would be... as little dough as possible?
2020-02-22T19:48:26 < BrainDamage> yes
2020-02-22T19:48:31 < Cracki> makes sense
2020-02-22T19:48:44 < Steffanx> that last one is more like some sauce and cheese is a slice of bread
2020-02-22T19:48:53 < Steffanx> last one of mr bd

2020-02-22T20:33:41 < ness> Does anyone know how SPI1 is supposed to be used on the STM32G030J6? The only pin with an AF for SPI1_SCK is the reset pin, which as far as i know, can't be used?
2020-02-22T20:35:22 < jpa-> you can disable the reset on some models
2020-02-22T20:37:32 < ness> how would i do that?
2020-02-22T20:37:53 < ness> and also how would i program/debug it if the reset pin and swd pins are used as i/O
2020-02-22T20:38:13 < jpa-> i assume for programming, you might have to power it up with NRST held down
2020-02-22T20:38:24 < Cracki> for debug you need either the reset (to get into debug) or the debug pins free for their function
2020-02-22T20:38:41 < ness> okay that makes sense
2020-02-22T20:39:06 < jpa-> but still looking on how to configure nrst function on G0
2020-02-22T20:39:33 < ness> it seems super weird to me that spi clock is only available on the reset pin
2020-02-22T20:39:38 < ness> why would they make it like that
2020-02-22T20:39:48 < jpa-> the 8-pin device is pretty weird one anyway
2020-02-22T20:39:59 < jpa-> it's larger than many of the larger pin count packages
2020-02-22T20:40:04 < Cracki> datasheet lists spi1_sck for pa1, pa5, pb3
2020-02-22T20:40:43 < ness> exactly
2020-02-22T20:40:53 < jpa-> AN5145 says "On STM32G0 there is the possibility to replace RESET functionality by a standard GPIO. A specific pin (PF2) replaces NRST if configured by appropriate value in options bytes."
2020-02-22T20:40:56 < Cracki> I'd do the assignments with cubemx. it helps you see the implications of a mapping
2020-02-22T20:41:36 < jpa-> but i don't quite see such an option byte
2020-02-22T20:41:46 < Cracki> this specific g0 doesn't have a pf2
2020-02-22T20:41:53 < Cracki> not enough pins yet
2020-02-22T20:42:20 < ness> it has the registers
2020-02-22T20:42:39 < Cracki> you'd want the pin if you want nrst to map there :P
2020-02-22T20:44:11 < Cracki> so uh... you said "The only pin with an AF for SPI1_SCK is the reset pin"
2020-02-22T20:44:25 < Cracki> but I find spi1_sck for pa1, pa5, pb3 only
2020-02-22T20:44:37 < jpa-> Cracki: and PA1 is on NRST pin in the 8-pin package
2020-02-22T20:44:42 < Cracki> this was the part you identified https://www.st.com/resource/en/datasheet/stm32g030j6.pdf
2020-02-22T20:44:43 < Cracki> ah
2020-02-22T20:44:45 < jpa-> (and PA5 and PB3 do not exist)
2020-02-22T20:45:11 < Cracki> I totally missed that
2020-02-22T20:45:53 < jpa-> i assume there is a way to disable the NRST functionality somehow, but can't see it
2020-02-22T20:46:42 < ness> Well, i guess i can just use spi2 for now
2020-02-22T20:46:50 < Cracki> >For the device in SO8N package, the PA0, PA1, and PA2 GPIOs are bonded with NRST on the pin 4. In order not to interfere with device functions, they must not be set in alternate function or in output but remain at all times in input configuration.
2020-02-22T20:47:06 < Cracki> so... spi1_sck only as spi slave
2020-02-22T20:47:16 < jpa-> weird
2020-02-22T20:47:29 < jpa-> and how much can you do even with input if it cannot go low :P
2020-02-22T20:50:23 < ness> thats funny
2020-02-22T20:50:32 < Cracki> rm figure 7 implies there's a filter on the nrst pin
2020-02-22T20:51:33 < jpa-> caution text under figure 7 implies one can configure something about the reset with option bytes, but i can't see such configuration in the option bytes description
2020-02-22T20:51:48 < Cracki> there must be a way to have nrst disabled, only sampled once during boot for programming... maybe
2020-02-22T20:54:30 < Cracki> no
2020-02-22T20:56:28 < Cracki> spi2 may be an option, unless they removed that for the 8-pin version
2020-02-22T20:57:59 < jpa-> RM0444 for STM32G031 has the option bytes description on how to configure NRST function, the same bits are marked reserved in STM32G030 reference manual
2020-02-22T20:58:26 < jpa-> i think it is just a bug in the reference manual and the stuff from RM0444 will probably work for G030 also
2020-02-22T20:59:27 < Cracki> spi2_sck is on pa0, but also on pb8 (pin 1), spi2_mosi is pb7 (also pin 1)... so nrst must be disable-able
2020-02-22T21:02:35 < ness> spi2_mosi is also on pa12
2020-02-22T21:04:46 < ness> i'm having trouble finding spi2_miso though

2020-02-22T21:53:55 < PaulFertser> Steffanx: the illness is called SARS-CoV-2 , caused by COVID-19 virus
2020-02-22T21:54:03 < PaulFertser> (luckily, not always)
2020-02-22T21:54:44 < Steffanx> Doesnt that depend on who's naming "scheme" you use PaulFertser.
2020-02-22T21:55:06 < PaulFertser> "Well over 200 virus strains are implicated in causing the common cold, with rhinoviruses being the most common." but it doesn't mean there're no CoVs that cause it too.
2020-02-22T21:55:44  * doomba looks up SARS-CoV-2 on digikey. finds results under Evaluation Demonstration Virii and Kits
2020-02-22T21:56:20 < Steffanx> So what did italy anounce a while back?
2020-02-22T21:56:25 < PaulFertser> Steffanx: are you not using WHO's naming scheme?
2020-02-22T21:58:15 < Steffanx> To be honest. i dont really care PaulFertser :P
2020-02-22T21:59:25 < PaulFertser> Steffanx: do not you like precise (fine) instrument, precise descriptions, precise thinking?
2020-02-22T22:02:34 < Steffanx> Sure, not in this case everyone knows what's meant by "corona virus".
2020-02-22T22:02:38 < Steffanx> or wuhan virus
2020-02-22T22:02:41 < Steffanx> or wahtever name you want to use
2020-02-22T22:02:51 < PaulFertser> Everyone knows what "xerox" is but it doesn't make it sound less stupid.
2020-02-22T22:03:41 < PaulFertser> Next thing you say is that it's OK to call engines that use belt-driven compressor "turbo".
2020-02-22T22:03:58 < PaulFertser> Or that you can "send an SMS".
2020-02-22T22:04:34 < Steffanx> Except that everyone and everywhere its called THE corona virus.
2020-02-22T22:04:45 < PaulFertser> Not in the Seeed's mail!
2020-02-22T22:05:36 < Steffanx> No, and ofcourse you can find a 1000 others not calling it that.
2020-02-22T22:06:54 < Steffanx> PaulFertser: next time i see you name something slightly ambiguous i will call it out. ok? :P
2020-02-22T22:08:58 < Steffanx> starting with "the Seeed's mail" ofcourse.
2020-02-22T22:09:02 < PaulFertser> Steffanx: btw, I got it wrong, COVID-19 is the disease. And you haven't noticed :(

2020-02-22T22:10:09 < Steffanx> oh, i didnt even noticed you swapped it.
2020-02-22T22:10:20 < Steffanx> contraints as in formula's and stuff? I hardly do that in sw
2020-02-22T22:11:03 < Steffanx> I just draw some sketch, set some dimensions add some features and be done with it. but then im hardly a pro

2020-02-22T22:25:43 < Steffanx> If you mean by "snap". Setting the contraints on certain parts (lines/arcs/whatever) and it will try to solve it using the non-constrainted parts (lines/whatever), then yes PaulFertser.
2020-02-22T22:26:04 < PaulFertser> Steffanx: kewl. So I was mislead. Thank you for the clarifications.

2020-02-22T23:50:47 < kakimir> what is the another type then?
2020-02-22T23:51:56 < kakimir> The 74LVC373A is functionally identical to the 74LVC573A, but has a different pinarrangement.

2020-02-23T05:00:41 < emeb_mac> anyone ever used those stand-alone touch sensor chips like MCHP MTCH101?
2020-02-23T05:01:15 < emeb_mac> need a few chls of touch sense -> logic and those seem like a simple sol'n
2020-02-23T05:03:25 < kakigate> how much it costs?
2020-02-23T05:03:42 < dongs> i used the atmel one, it was garbage
2020-02-23T05:03:52 < dongs> felt like i was progamming an atmega with some touchshit thrown in externally
2020-02-23T05:03:54 < emeb_mac> like 0.30
2020-02-23T05:03:57 < dongs> just use a fucking F042 or something
2020-02-23T05:04:25 < kakigate> avr
2020-02-23T05:04:47 < emeb_mac> could do. I've go a rail of f030 parts and IIRC those have a few chls of touch
2020-02-23T05:05:27 < dongs> yeah
2020-02-23T05:05:29 < kakigate> you should check 8bit avr portfolio
2020-02-23T05:05:45 < dongs> STM touch is also noice because you ened less caps/whatever shit per channel
2020-02-23T05:06:05 < dongs> i think theres only one cap per group where in atmel shit you need one cap per button or someshit
2020-02-23T05:06:06 < kakigate> there is multichannel touch sensing starting from devices around price 0.5
2020-02-23T05:08:13 < emeb_mac> damn - no touch sense on F030
2020-02-23T05:08:30 < emeb_mac> gotta go up to F042 for that. I've got a few, but seems a bit overkill.

2020-02-23T06:49:06 < Jak_o_Shadows> hmmm. How am I meant to kick off a set of DMA i2c transactions? I currently just start a dummy transaction with fake data, then send the actual transfers in the DMA transfer complete interrupts.
2020-02-23T06:49:38 < Jak_o_Shadows> But then I think the DMA interrupt gets done whilst I'm waiting for the byte transfer complete, and before I send the stop signal.
2020-02-23T06:50:12 < Jak_o_Shadows> It works for the middle lot, because you can't interrupt the interrupt.
2020-02-23T06:51:17 < Jak_o_Shadows> https://github.com/Jak-o-Shadows/stm32-OLED/blob/master/src/main.c , for the record, But i guess i'm a bit confused about whree you check that it's actually sent in this kind of paradigm

2020-02-23T09:46:28 < jpa-> Jak_o_Shadows: the usual way is to use the I2C interrupts on I2C_SR1_ADDR etc. to handle the initial setup of the transfer, and then have a dma transfer for the main data part of it
2020-02-23T09:46:45 < jpa-> your current code seems like it will just block in the interrupt, negating any benefit from DMA in the first place
2020-02-23T09:46:59 < jpa-> and in many cases, I2C is so slow that it is easier to just use interrupts anyway
2020-02-23T09:48:23 < Jak_o_Shadows> ohhh, I get you. Move most of my logic to the i2c interrupt, and have the DMA interrupt be a lot dumber and simpler
2020-02-23T09:49:03 < Jak_o_Shadows> Yeah, true. would be nice to use the DMA still though
2020-02-23T09:49:07 < jpa-> yeah - in normal cases you'd just have a one DMA transfer and when it is done tell I2C to stop - but of course if there are many buffers to transfer or something, you can start a new transfer in the DMA interrupt
2020-02-23T09:50:13 < jpa-> also, seeing as you are on STM32F1, be aware that the I2C peripheral there is a kind of fiddly and has a lot of errata of the form "if you don't do these steps in exactly correct order and correct timing, I2C peripheral will randomly lock up"
2020-02-23T09:50:32 < Jak_o_Shadows> oh, yeah, looking at the errata is a good idea
2020-02-23T09:51:05 < jpa-> the errata sheet is also somewhat difficult to follow, chibios I2C driver is a good reference also
2020-02-23T09:51:06 < Jak_o_Shadows> I should remember that, it's bitten me often enough

2020-02-23T14:41:07 < jpa-> wouldn't want anyone accidentally putting some ethernet controllers in place of my transistors :P
2020-02-23T14:41:33 < karlp> si3400 doesn't have the g/s diodes in ao3400.
2020-02-23T14:42:09 < karlp> ao3400 has higher Vgs
2020-02-23T14:42:29 < englishman> Double Happiness Semiconductor Co.
2020-02-23T14:42:33 < jpa-> hmm, g/s diodes? i don't see them on ao3400 datasheet
2020-02-23T14:43:18 < karlp> no, I just reaslised I was looking at the replacement AOSS32334C datasheet
2020-02-23T14:43:23  * karlp opens a third window
2020-02-23T14:44:14 < jpa-> 10µA gate leakage current? :D
2020-02-23T14:45:33 < karlp> right, si/ao 3400 are ~same.
2020-02-23T14:46:21 < jpa-> at least closer to eachother than AOSS32334
2020-02-23T14:48:08 < karlp> yeah, aoss32334 is a "bit" better in most things.
2020-02-23T14:49:19 < jpa-> except for driving from 3.3V logic
2020-02-23T14:49:33 < jpa-> which is what i mostly use AO3400 for
2020-02-23T14:49:43 < karlp> hrm, gate threshold of 1.8 instead of 1.05, yeah
2020-02-23T14:49:47 < karlp> not nearly as "on"
2020-02-23T14:50:23 < jpa-> and Rds_on not even specified at 3.3V, the graph just shoots upwards

2020-02-23T14:51:39 < karlp> yeah, shit, i missed a row, 3400 has the 2.5V line item
2020-02-23T14:52:22 < jpa-> and the 10µA leakage seems ridiculous also, wouldn't work reliably with a 100 kohm pull-up on the gate
2020-02-23T15:10:05 < karlp> yeah, 3400 was 100nA, I wonder if that's a typo?
2020-02-23T15:10:08 < karlp> should be 10nA?
2020-02-23T15:10:33 < karlp> turn off is faster, turn on is slower too.
2020-02-23T15:10:38 < karlp> I wonder why they nrnd'd it?
2020-02-23T15:12:14 < jpa-> i wonder what the G-S diodes are about; ESD protection apparently, but what's the point? i could see some benefit if it had internal limiting to 20V Vgs specified so that one could use it easier for switching higher voltages also, though with 30V Vds max not much point there either
2020-02-23T15:12:40 < jpa-> first time i see esd protection on a discrete mosfet

2020-02-23T16:50:59 < bitmask> making copper sulphate by passing current through dilute sulfuric acid with copper electrodes, then im gonna use the copper sulphate to electroplate/electroform stuff 
2020-02-23T16:53:20 < Steffanx> isnt copper sulphate cheapish ?
2020-02-23T16:53:31 < bitmask> yes, I just wanted to make it myself though,

2020-02-23T17:01:28 < bitmask> the only 3A ones I have dont have a heat sink and were getting crazy hot, I wanted more than 3A too although I dont think this will go that high even though its technically good for 4.5A, maybe if I keep the fan on it would be fine that high.  I then found out I was using too high a voltage/current so now im running it lower
2020-02-23T17:01:37 < Cracki> ic
2020-02-23T17:07:38 < karlp> I would have thought the copper plating using copper sulfate would have been way more interesting than just making copper sulfate.
2020-02-23T17:07:49 < karlp> it's dirt cheap, used in gardening.
2020-02-23T17:09:18 < Steffanx> bitmask's mind works differently. ;)
2020-02-23T17:10:02 < karlp> I guess :)
2020-02-23T17:10:13 < bitmask> I think they are both interesting, why not do both
2020-02-23T17:11:00 < bitmask> seeing a beautiful blue appear from red colored copper is interesting
2020-02-23T17:11:06 < karlp> I guess.
2020-02-23T17:11:12 < bitmask> and then growing crystals and purifying it
2020-02-23T17:11:25 < karlp> opening a black light proof jar and seeing a big sea of fluffy blue crystals is pretty rad on it's own.

2020-02-23T17:37:38 < invzim> MAX16956 should work, it's a bit bigger - but more expensive

2020-02-23T17:40:33 < zyp> I'm thinking about making some fpga shit to play around with, and since it's gonna end up with an expensive BOM anyway, I'm tempted to put that MPS quad thing with builtin inductors on it

2020-02-23T17:41:04 < zyp> I think so

2020-02-23T17:42:50 < invzim> I got away with using LDO's

2020-02-23T17:43:48 < Steffanx> oh i recall digikeying/mousering it and it didnt show any stock at all
2020-02-23T17:44:37 < emeb> most mfg recommendations for FPGA current draw are way overspeced - based on max freq, max utilization.
2020-02-23T17:44:52 < zyp> invzim, ECP5
2020-02-23T17:44:57 < invzim> I suspect a lot of the 'fpga power solutions', are made for the geo/oil/defence market
2020-02-23T17:45:59 < emeb> I got a ULX3S a while back - ecp5 85k. Did some fooling w/ it. Works fine.
2020-02-23T17:46:33 < emeb> using the FOSS toolchain - very easy.
2020-02-23T17:46:35 < zyp> emeb, looked at those, seems like nobody are actually stocking them
2020-02-23T17:46:41 < invzim> aoz ftw, digikey AND lcsc for reasonable price is a win in my book
2020-02-23T17:47:01 < zyp> but yeah, the FOSS toolchain is what makes them interesting
2020-02-23T17:47:13 < emeb> zyp: yeah - they're kind of hard to find. I got mine as a freebie from the CEO of the company that does the FOSS tools.
2020-02-23T17:48:40 < emeb> looks like there's a crowdsource campaign for Greg Davil's "Orange Crab" ecp5 + dram feather board coming up soon though. 
2020-02-23T17:48:46 < zyp> it seems like at the moment if you want the ecp5, you've got the choice of two official boards from lattice, a couple of actual products that can be repurposed and a bunch of open source designs that nobody is making for sale but you can fab and assemble yourself
2020-02-23T17:49:04 < emeb> right
2020-02-23T17:49:09 < zyp> and then a bunch of stuff that is coming, like that orange crab and the tinyfpga-ex
2020-02-23T17:49:34 < emeb> I know a few folks who've bought those video wall driver boards. Cheap, but strange I/O.
2020-02-23T17:49:48 < invzim> are they great, or is it just the open source toolchain that is the attraction?
2020-02-23T17:49:51 < zyp> I ordered two of those, but they are still in shipping
2020-02-23T17:49:54 < zyp> invzim, the latter
2020-02-23T17:50:25 < emeb> The ecp5 parts are roughly on par with Spartan 6 for features.
2020-02-23T17:50:33 < zyp> that's my impression too
2020-02-23T17:50:37 < emeb> and prices aren't significantly lower.
2020-02-23T17:50:52 < zyp> but not having to deal with ISE is a huge benefit :)
2020-02-23T17:50:58 < emeb> this!
2020-02-23T17:51:24 < invzim> for what it's worth, I have had zero issues with quartus - simple install that doesn't rape your system
2020-02-23T17:51:31 < emeb> However - I've tried to do a few DSP things with the FOSS toolchain and it's not quite as polished there as the vendor tools.
2020-02-23T17:51:50 < emeb> Seems to have trouble inferring multipliers, large adders, etc.
2020-02-23T17:52:10 < zyp> yeah, I read that inference for ecp5 isn't complete yet
2020-02-23T17:52:18 < invzim> man, this channel is gold - thanks so much for the aoz \o/
2020-02-23T17:53:05 < emeb> I've done a lot of work w/ FOSS tools on the Lattice ice40 family. That's also pretty good (mostly same tools w/ different target). Also has trouble with the math inference.
2020-02-23T17:54:13 < qyx> fuk all omega2s modules on mouser are sold out
2020-02-23T17:55:16 < emeb> invzim: I saw someone mention installing latest Vivado was > 40GB
2020-02-23T17:55:24 < qyx> there were like >1000 available yesterday or so
2020-02-23T17:55:32 < Steffanx> heh. china died.
2020-02-23T17:55:33 < zyp> emeb, by the way, since you know fpga design; if I wanted to make a board with a bunch of ram, is there any reason I shouldn't put down a ddr3 sodimm socket instead of plain ddr3 memory chips, assuming I've got enough IO to handle the 64-bit wide bus?
2020-02-23T17:56:03 < emeb> zyp: can't think why that wouldn't work.
2020-02-23T17:56:24 < emeb> aside from size & routing issues it should be equiv.
2020-02-23T17:56:25 < zyp> my understanding is that the disadvantages using a standard module is bus width and size
2020-02-23T17:56:30 < zyp> yeah
2020-02-23T17:57:05 < zyp> additionally the module should be decoupled and terminating and all, so routing should be pretty simple
2020-02-23T17:57:11 < zyp> terminated*
2020-02-23T17:57:19 < emeb> most FPGA devboards are going for tightest possible layout so that's probably why you never see it.
2020-02-23T17:58:03 < emeb> advantage of using a sodimm is that you could put non-RAM stuff in the socket too.
2020-02-23T17:58:06 < emeb> MOAR I/O!
2020-02-23T17:58:15 < zyp> yes, that's also something I thought about
2020-02-23T17:58:18 < invzim> ddr3 controllers may be non-trivial to get write/get-working
2020-02-23T17:58:28 < zyp> good thing it's already written then :)
2020-02-23T17:58:43 < emeb> yeah - lots of free libs for stuff like that.

2020-02-23T17:59:16 < invzim> the opencores stuff I've tested is garbage (not tried ddr controllers)
2020-02-23T17:59:24 < emeb> not opencores
2020-02-23T17:59:26 < zyp> I'm planning to use litedram
2020-02-23T17:59:33 < zyp> litex overall looks great
2020-02-23T17:59:35 < emeb> right - litex, migen, etc.
2020-02-23T18:00:25 < emeb> basically just specify a full soft processor SoC at a high level and let the tools build it for you.
2020-02-23T18:00:30 < zyp> yeah
2020-02-23T18:00:51 < emeb> I need to get familiar with that stuff.
2020-02-23T18:00:52 < zyp> I tried building the example SoC for that led driver board the other day to check that the toolchain is working
2020-02-23T18:01:08 < zyp> went fine, now I just need the boards to arrive so I can test it :)
2020-02-23T18:01:30 < zyp> and then I want a board with more IO to play with
2020-02-23T18:01:49 < emeb> sounds like fun.
2020-02-23T18:02:10 < zyp> e.g. people have been experimenting with doing usb3 with the ecp5 serdes
2020-02-23T18:02:28 < emeb> yeah, saw that.
2020-02-23T18:03:33 < emeb> Has anyone done anything with those Colorlight video wall boards besides just document them?
2020-02-23T18:03:46 < zyp> I wanna try doing some ethernet bridging stuff
2020-02-23T18:04:14 < emeb> ie - does litex support the GigE PHYs on that board?
2020-02-23T18:04:19 < zyp> yes
2020-02-23T18:04:29 < emeb> sweeet
2020-02-23T18:05:34 < zyp> PHYs shouldn't be too hard to support anyway, if you can do RGMII, you should be able to talk to any RGMII PHY with little work
2020-02-23T18:06:02 < sync> hm, I should get one of those ecp5 boards and finally make my rom emulator
2020-02-23T18:06:55 < qyx> Steffanx: but but I just received boards for them and now they are unobtainable
2020-02-23T18:07:39 < zyp> I figure if I can get usb3 and sodimm working, I have a good basis for a logic analyzer too
2020-02-23T18:07:56 < zyp> put in an 8GB stick and you can do pretty long fast captures
2020-02-23T18:10:44 < invzim> zyp: I scoped usb3 a while back and figured the easiest would be to use this https://www.ftdichip.com/Products/ICs/FT600.html
2020-02-23T18:11:17 < zyp> I'm looking for fun, not easy
2020-02-23T18:11:51 < emeb> heh
2020-02-23T18:12:43 < emeb> lol @ ebay listings for Colorlight boards. $28 + $30 shipping. Or $49 free shipping.
2020-02-23T18:12:46 < zyp> if I were designing a product or had a specific problem to solve, then sure, using a usb3 bridge chip would be the safe way to go
2020-02-23T18:14:08 < invzim> https://github.com/MiSTer-devel/Main_MiSTer/wiki <- this project has A LOT of plumbing in place, unless you want to be the plumber :)
2020-02-23T18:14:32 -!- fc5dc9d4_ is now known as fc5dc9d4
2020-02-23T18:14:32 < invzim> gig ethernet, linux and whatnot
2020-02-23T18:14:42 < zyp> a lot of plumbing for what?
2020-02-23T18:14:44 < emeb> vs Aliexpress where they're $15 + $5 shipping
2020-02-23T18:15:51 < emeb> isn't MIST just a bunch of add-on boards for normal Terasic boards?

2020-02-23T18:18:48 < Steffanx> You have to keep up mate.
2020-02-23T18:19:10 < zyp> invzim, I figure litex would provide all the plumbing I don't want to do myself: https://github.com/enjoy-digital/litex
2020-02-23T18:20:39  * emeb searches for pre-built litex projects for ULX3S
2020-02-23T18:21:12 < invzim> looks cool, kind of like buildroot for fpga's :)
2020-02-23T18:21:19 < emeb> yep
2020-02-23T18:21:48 < emeb> I mean, Vivado and Quartus kinda do that sort of thing, but with a lot more pain.
2020-02-23T18:22:31 < emeb> as in "lots of manual operations + GUI poking" instead of just makefile simplicity.
2020-02-23T18:22:39 < zyp> emeb, https://github.com/litex-hub/linux-on-litex-vexriscv
2020-02-23T18:23:04 < invzim> I didn't even try, on my design I stuck a 2 USD stm32 on it to do 'software stuff'
2020-02-23T18:23:18 < emeb> zyp: thx for linky
2020-02-23T18:23:28 < emeb> need the easy reader to get started.
2020-02-23T18:24:02 < emeb> invzim: I did a few boards with STM32 + FPGA too. 
2020-02-23T18:24:30 < emeb> but also did full up soft processor experiments on low-end parts. Kinda fun
2020-02-23T18:24:37 < invzim> emeb: my one and only :) https://irkenlabs.com/69-the-retro-scaler-a1-is-here
2020-02-23T18:25:03 < zyp> I did a spartan3a addon board for my stm32 devboard, but never really got anything done with it
2020-02-23T18:25:13 < emeb> invzim: stm + fpga -> http://ebrombaugh.studionebula.com/embedded/f303_ice5/index.html
2020-02-23T18:25:38 < zyp> I mean, I did a FSMC slave to wishbone master translator with migen, which appeared to work fine
2020-02-23T18:26:23 < emeb> invzim: and also -> https://github.com/emeb/up5k_vga
2020-02-23T18:27:12 < invzim> emeb: nice! 
2020-02-23T18:27:48 < emeb> invzim: that UP5K part costs ~$6 and comes in QFN48 so it's super easy to DIY
2020-02-23T18:28:47 < invzim> instead of using resistors for video, you can use this https://lcsc.com/product-detail/Codec-ICs_CORPRO-GM7123C_C245020.html
2020-02-23T18:28:59 < invzim> gives you proper 75ohm output impedance, and is pin compatible with adv7123
2020-02-23T18:29:50 < BrainDamage> great, schools closed and public activities banned
2020-02-23T18:30:18 < Steffanx> awh, in the region you live in BrainDamage?
2020-02-23T18:30:42 < emeb> invzim: cool chip. but 4-bit R2R ladder DACs are cheap & cheerful and also have proper 75 ohm source impedance.
2020-02-23T18:30:43 < BrainDamage> yes
2020-02-23T18:31:10 < invzim> italy?
2020-02-23T18:32:09 < kakimir> BrainDamage is not available
2020-02-23T18:32:23 < BrainDamage> north italy, yes
2020-02-23T18:32:36 < BrainDamage> the main points are approx 50km away
2020-02-23T18:32:56 < invzim> oh man that sucks
2020-02-23T18:33:11 < kakimir> guess there is daily traffic between that area and your area BrainDamage
2020-02-23T18:33:15 < BrainDamage> so far my city is clean, as in the only one sick got transported from a different city, already in isolation because mine has a better hospital
2020-02-23T18:33:17 < BrainDamage> yes
2020-02-23T18:33:17 < kakimir> commuting
2020-02-23T18:33:17 < invzim> easy to be complacent about it when it's on the other side of the planet
2020-02-23T18:33:18 < specing> wouldn't it be simpler to like just close the borders before the virus reaches your area?
2020-02-23T18:33:34 < BrainDamage> I live on a border city
2020-02-23T18:33:45 < BrainDamage> I bet the borders are going to close soon-ish
2020-02-23T18:33:54 < specing> nah
2020-02-23T18:33:55 < emeb> We had a couple cases here in my city a few weeks ago. Immediately quarantined and so far no others.
2020-02-23T18:34:00 < kakimir> how is panic level BrainDamage?
2020-02-23T18:34:03 < kakimir> 0-10
2020-02-23T18:34:08 < BrainDamage> 4
2020-02-23T18:34:18 < kakimir> reasonable
2020-02-23T18:34:38 < BrainDamage> some tension, people talk about it routinely, but people still go out, etc
2020-02-23T18:40:59 < specing> I think this virus is already uncontainable
2020-02-23T18:41:15 < kakimir> do you prep BrainDamage?
2020-02-23T18:41:27 < kakimir> are you like that?
2020-02-23T18:41:56 < BrainDamage> only thing i have is a couple of bottles of water in a bag
2020-02-23T18:43:51 < doomba> lol
2020-02-23T18:44:12 < doomba> ya'll are reading too much FUD news clickbait sensationalist nonsense
2020-02-23T18:44:40 < BrainDamage> the water bottles is because I live in an area prone to flooding
2020-02-23T18:44:46 < BrainDamage> not because of the virus
2020-02-23T18:44:54 < BrainDamage> i had them since years
2020-02-23T18:45:11 < doomba> remember we didn't have social media and surveillance capitalism was in its infancy back in the SARS days.
2020-02-23T18:45:46 < doomba> people were told to be terrified of SARS through the dinosaur news media.
2020-02-23T18:45:47 < jadew> doomba, SARS didn't make it out
2020-02-23T18:45:56 < doomba> jadew: i'm pretty sure it did
2020-02-23T18:45:56 < jadew> that's why it didn't make it out
2020-02-23T18:46:15 < jadew> and it's the reason why WHO downplayed the danger this time
2020-02-23T18:46:21 < jadew> and this is the result...
2020-02-23T18:46:25 < jadew> an actual pandemic
2020-02-23T18:46:37 < doomba> we just didn't have the tools / media clickbait sites to tell us where SARS was spreading. i have no doubt SARS killed people 
2020-02-23T18:46:44 < doomba> *killed people in other countries than china
2020-02-23T18:47:01 < jadew> they are monitoring this shit since forever
2020-02-23T18:47:16 < doomba> right
2020-02-23T18:47:21 < doomba> but what's worse than coronavirus?
2020-02-23T18:47:36 < jadew> it's unclear at this point
2020-02-23T18:47:43 < doomba> no it's perfectly clear
2020-02-23T18:47:44 < zyp> I'm not sure what you mean by «not made it out», when wikipedia states «… resulting in 774 deaths reported in 17 countries …»
2020-02-23T18:47:50 < jadew> it could be the worst yet, in sheer number of deaths
2020-02-23T18:48:02 < jadew> zyp, yeah, but it was contained
2020-02-23T18:48:17 < jadew> this doesn't seem to be contained any longer
2020-02-23T18:48:57 < BrainDamage> the numbers of infected in my region are only going to grow in the next weeks due to the incubation period
2020-02-23T18:49:00 < jadew> with several untracked outbreaks in Iran and various countries in Africa, it's just loose
2020-02-23T18:49:17 < BrainDamage> as in, there's going to be quite a few people who are infected but don't have symptoms yet
2020-02-23T18:49:19 < jadew> BrainDamage, yeah, if none of those people made it out and seeded other regions
2020-02-23T18:49:21 < doomba> economic paralysis caused by irrational fear of coronavirus based on lack of facts based reporting by news media is what CAN VERY MUCH SO kill millions of people through food and medicine shortages and civil unrest.
2020-02-23T18:49:47 < doomba> that's why the WHO is being very careful not to scare
2020-02-23T18:49:55 < jadew> doomba, the facts are that the current mathematical models are predicting that 60% of the population is going to get infected
2020-02-23T18:50:09 < jadew> another fact is that WHO has advised ALL countries to seriously prepare for this thing
2020-02-23T18:50:18 < englishman> bye bye, interesting fpga conversation
2020-02-23T18:50:24 < BrainDamage> sorry >.>
2020-02-23T18:50:32 < doomba> FGPA = coronavirus
2020-02-23T18:50:34 < zyp> no, we can get back to that
2020-02-23T18:50:40 < specing> doomba: you do realise that 0.2% mortality rate on 7 billion people = 14 million dead?
2020-02-23T18:50:57 < jadew> specing, except it's 2%
2020-02-23T18:51:03 < doomba> specing: more people die every year of heart disease by a huge margin.
2020-02-23T18:51:04 < jadew> and it would result in ~100 million
2020-02-23T18:51:05 < specing> jadew: where is the other 40% living?
2020-02-23T18:51:09 < specing> jadew: oh, yeah
2020-02-23T18:51:13 < specing> 140 million dead
2020-02-23T18:51:30 < englishman> ft600 should be a great replacement for the obtuse fx3
2020-02-23T18:51:32 < specing> doomba:^
2020-02-23T18:53:00 < zyp> englishman, it'd be even greater with a mature usb3 softcore so all you need is a serdes
2020-02-23T18:53:54 < englishman> surprised there isnt already for ec5 but i guess softcore+ulpi is pretty demanding
2020-02-23T18:54:07 < zyp> there is

2020-02-23T18:54:42 < doomba> still only 2% ?
2020-02-23T18:55:53 < doomba> we have fertility "crisis" in most of the western world combined with a bunch of boomers who will soon be dead.
2020-02-23T18:56:35 < specing> doomba: what fertility crisis?
2020-02-23T18:56:37 < doomba> i think we're going to see a sharp decline in world population in our lifetime. could that mean FPGA get even more ridiculously expensive?
2020-02-23T18:57:18 < doomba> i've been wanting to explore FPGA but haven't had the chance yet

2020-02-23T18:59:20 < doomba> i heard that the "code" you run on fpga isn't sequental?
2020-02-23T18:59:21 < qyx> on a spartan3
2020-02-23T18:59:27 < doomba> like it all runs simultaneously?
2020-02-23T18:59:28 < BrainDamage> yes, it runs on parallel
2020-02-23T18:59:36 < doomba> yea see that's just weird lol
2020-02-23T18:59:49 < zyp> it's not weird, because it's not code, it's configuration
2020-02-23T18:59:49 < BrainDamage> just like separate wires on a digital logical circuit does
2020-02-23T19:00:03 < jadew> doomba, that's because you're not describing code, but a logic circuit
2020-02-23T19:00:09 < BrainDamage> exactly
2020-02-23T19:00:11 < doomba> ok so the "code" you write is really just hooking up circuitry?
2020-02-23T19:00:18 < BrainDamage> hooking up operations
2020-02-23T19:00:23 < jadew> which is composed of various sections which can operate independently of each other
2020-02-23T19:00:26 < doomba> what do you mean by operations. logical operations?
2020-02-23T19:00:29 < BrainDamage> yes
2020-02-23T19:00:29 < zyp> a fpga is a pile of muxes and lookup tables

2020-02-23T19:01:11 < doomba> oh ok - so you're not totally starting from scratch then?
2020-02-23T19:01:28 < BrainDamage> well, the synthesis engine lets you use high level operations
2020-02-23T19:01:29 < doomba> they have some built-in boiler plate already in the hw?
2020-02-23T19:01:50 < BrainDamage> so you can say do a multiplication for a 8 bit bus
2020-02-23T19:01:58 < zyp> doomba, correct
2020-02-23T19:02:00 < doomba> one of those lattice parts i think i was reading said it had hardware transceivers for uart/spi/whatever
2020-02-23T19:02:02 < BrainDamage> and yes, some operations are implemented in hw
2020-02-23T19:02:08 < jadew> you can define registers and then tell it what to do with them
2020-02-23T19:02:12 < BrainDamage> because it's more optimized
2020-02-23T19:02:15 < doomba> i'm assuming those parts are not part of the fpga ... meaning you can't overwrite them with "code" ?
2020-02-23T19:02:31 < BrainDamage> no but you can decide how to hook them up
2020-02-23T19:02:34 < zyp> doomba, there's muxes around them so you still configure what hooks up to them
2020-02-23T19:02:41 < BrainDamage> every block in the fpga is in a crossbar matrix
2020-02-23T19:02:41 < doomba> oh cool
2020-02-23T19:02:47 < doomba> that's like the g0 DMAMUX shit
2020-02-23T19:02:55 < BrainDamage> so you can connect everything to everything
2020-02-23T19:03:12 < jadew> doomba, except you don't have to specify things at that level
2020-02-23T19:03:22 < jadew> you just say, for each rising edge of the clock
2020-02-23T19:03:34 < jadew> add 1 to this register I just made up, that has 8 bits
2020-02-23T19:04:04 < jadew> you don't care about how things are connected (usually)
2020-02-23T19:04:06 < BrainDamage> you can inspect the implementation or see the equivalent circuit, but for most things it's not necessary
2020-02-23T19:04:13 < BrainDamage> it's like looking at asm
2020-02-23T19:04:14 < jadew> for most stuff you just describe the operations you want to perform
2020-02-23T19:04:19 < jadew> and the synthesizer figures out the rest
2020-02-23T19:04:29 < BrainDamage> you only care for high performance things
2020-02-23T19:04:31 < zyp> yeah, just like you generally don't write assembly, you generally don't think much about the actual fpga architecture
2020-02-23T19:04:44 < doomba> also i haven't had any reason to use fpga for anything yet
2020-02-23T19:04:54 < zyp> you describe the logic you want, the synthesizer makes it happen
2020-02-23T19:05:04 < doomba> err... nothing i want to do has made me want to say, "i could learn fpga with this"
2020-02-23T19:05:09 < srk> zyp: you do cause you run in parallel :)
2020-02-23T19:05:20 < zyp> srk, that has nothing to do with it
2020-02-23T19:05:48 < doomba> for me, i have to set some goal in order to learn something new.
2020-02-23T19:06:11 < doomba> if i just buy fpga dev kit or whatever - it will sit there beacuse i have nothing to do with it.
2020-02-23T19:06:13 < srk> just in time learning :)

2020-02-23T19:06:35 < zyp> srk, in a programming language you describe a sequence of operations, in a HDL you describe logic blocks
2020-02-23T19:09:03 < BrainDamage> a lot of operations that are done with a micro, in a way, are expressed in a natural way in a fpga
2020-02-23T19:09:04 < srk> zyp: sometimes you just describe functions :) 
2020-02-23T19:09:33 < BrainDamage> as long as you can describe your problem as a pipeline, like eg a signal processing chain, a fpga becomes quite easy to use

2020-02-23T19:20:17 < emeb> what would segger possible contribute?
2020-02-23T19:21:18 < doomba> segger f-link. like j-link but for fpgas. everyone would call it fuck-link because it costs $750
2020-02-23T19:21:21 < Cracki> they make programming/debugging dongles and software (ozone and that complete IDE) for arm and risc v
2020-02-23T19:22:35 < Cracki> granted, they (likely) don't contribute to gcc
2020-02-23T19:24:41 < zyp> I think j-link already supports fpgas in some capacity
2020-02-23T19:26:10 < zyp> ah, seems to be mainly for debugging the CPU in hybrid fpgas like zynq
2020-02-23T19:26:22 < Cracki> fpgas use jtag too, or is there something newer already?
2020-02-23T19:26:29 < BrainDamage> jtag
2020-02-23T19:26:49 < BrainDamage> with some extensions depending on the brand
2020-02-23T19:27:11 < BrainDamage> jtag is sufficiently flexible for most things, after all it's a transport and enumeration mechanism
2020-02-23T19:27:19 < BrainDamage> what you put in it is what you want
2020-02-23T19:29:30 < zyp> yeah
2020-02-23T19:41:04 < emeb> don't most FPGA tools support SVF output so you can use any old jtag dongle to play them into the target?
2020-02-23T19:41:09 < zyp> I believe so
2020-02-23T19:42:16 < emeb> I mean, most vendor tools are smarter than that and can use special knowledge of the target to do fancy things like compression and talking to internal structures like ILAs etc.
2020-02-23T19:42:30 < emeb> but just for quick downloads an SVF is usually enough.
2020-02-23T19:42:41 < zyp> jtag itself is basically an extended shift register protocol with a mechanism to let you select between registers to shift information into and out of
2020-02-23T19:42:50 < zyp> plus a few defined standard registers
2020-02-23T19:43:07 < doomba> by registers you mean the different taps?
2020-02-23T19:43:14 < zyp> no, registers

2020-02-23T19:49:11 < zyp> a jtag tap got a state machine that lets you choose between shifting an instruction register and a data register with the JTMS pin, the instruction register selects which data register to shift
2020-02-23T19:50:13 < zyp> there's also a bypass option for the instruction register (all ones IIRC) that lets you shift straight through the data register
2020-02-23T19:50:31 < zyp> so when you chain multiple taps, you put the ones you're not actively using into bypass

2020-02-23T20:52:39 < englishman> fag-connect spotted
2020-02-23T20:54:05 < Steffanx> ohno we'll all die now?
2020-02-23T20:54:12 < Steffanx> *we will
2020-02-23T20:54:15 < jpa-> but 10-pin fag-connect
2020-02-23T20:54:19 < jpa-> how gay is that
2020-02-23T20:55:29 < jpa-> when will the chinese start making cheap tag connect cables
2020-02-23T20:55:59 < zyp> 10-pin is fine enough but fuck the huge holes around it
2020-02-23T20:57:02 < Cracki> you can get rid of the four HUGE holes because those are only for the latch
2020-02-23T20:57:17 < zyp> yes
2020-02-23T20:57:32 < Cracki> for the 6pin there's a plug you can put on from the other side
2020-02-23T20:57:39 < zyp> 10-pin too
2020-02-23T20:57:47 < Cracki> I don't trust that plug
2020-02-23T20:57:53 < zyp> works fine for me
2020-02-23T20:58:00 < Thorn> also why this enormous mcu package
2020-02-23T20:58:07 < Cracki> same so far but I wonder when it might wear out
2020-02-23T20:58:29 < Cracki> do they have that lpc4337 in anything smaller?
2020-02-23T20:58:37 < zyp> mine has lasted for years, losing them is a bigger problem than them wearing out
2020-02-23T20:59:22 < jpa-> i handled my ghettoplug with greasy fingers and it got too slippery
2020-02-23T20:59:34 < Cracki> Thorn, lemme know how it performs if you get a v10 hw
2020-02-23T20:59:44 < Thorn> this tag-connect looks to be intended for factory programming the mcu, not for the end user?
2020-02-23T20:59:45 < Cracki> drop in dish water?
2020-02-23T20:59:50 < Cracki> correct
2020-02-23T21:00:02 < Cracki> you use the big 20pin thing
2020-02-23T21:00:21 < Cracki> there are breakouts for .05" cortex m cable and all other types you can think of
2020-02-23T21:00:22 < jpa-> i'd understand TC2050 (10-pin) better if it at least had uart or something useful like that
2020-02-23T21:00:59 < zyp> jpa-, useful is relative
2020-02-23T21:01:12 < Cracki> 6-pin is plenty for swd with swo but maybe they just took the 10-pin cortex m pinout and copied it
2020-02-23T21:01:24 < zyp> my workstuff is using the 10-pin because it got some signals that the 6-pin are missing
2020-02-23T21:01:30 < jpa-> i guess full jtag is useful for fpgas and stuff like that, but can't see the point for processors that have swd
2020-02-23T21:01:39 < zyp> I mean, first of all I don't think the cortex-r mcu got swd
2020-02-23T21:01:57 < Cracki> cortex m header has two grounds, one key, one "grounddetect", and a NC/TDI
2020-02-23T21:01:59 < Thorn> I've got both v9.4 and v9.6 and they both have buffers, why v10.1 without them
2020-02-23T21:01:59 < zyp> and secondly it needed jtrst or some shit also
2020-02-23T21:02:10 < Cracki> if you aren't using jtag, you an drop four of those
2020-02-23T21:02:13 < Thorn> is this Chinese improvisation?
2020-02-23T21:02:39 < zyp> jpa-, agreed otherwise
2020-02-23T21:02:53 < Cracki> Thorn, some broken chinese to english translation _might_ have said that without buffer it's faster
2020-02-23T21:03:21 < zyp> jpa-, I prefer TC2030 for swd, but I don't mind using TC2050 for jtag where swd won't do
2020-02-23T21:04:11 < jpa-> zyp: :)

2020-02-23T21:06:36 < Thorn> by being powered from the Vt pin
2020-02-23T21:06:46 < Thorn> no idea, not documented. probably 3.3V
2020-02-23T21:07:03 < Cracki> 5v tolerance, 1.2 to 3.3v it says
2020-02-23T21:07:13 < Cracki> about halfway into the picture in the comment
2020-02-23T21:07:53 < zyp> reminds me of when I were hooking up a LA to some signals in a device with a non-isolated PSU
2020-02-23T21:08:17 < Cracki> uh they mix those pictures... v10.2 has some chips at the outputs, unversioned views don't

2020-02-23T21:08:43 < Thorn> 1.2...3.3 sounds like the buffered version
2020-02-23T21:08:51 < zyp> thought I'd get by with a usb-isolator, but I overlooked the fact that it would only do FS, and a fx2-based LA doesn't do well at other speeds than HS :p

2020-02-23T22:08:29 < Cracki> which reminds me, I used to live in a house that had lead pipes in the basement. I think they were out of use
2020-02-23T22:08:36 < BrainDamage> but if you eat raw copper you'll get CuO and Cu2O formed as reaction
2020-02-23T22:09:04 < BrainDamage> once lead gets a passivation layer of limescale is "ok"
2020-02-23T22:09:20 < BrainDamage> but some waters are not enough alkaline for it, or worse, slightly acidic
2020-02-23T22:09:28 < BrainDamage> and the lead will dissolve
2020-02-23T22:09:29 < qyx> or tinned lead piopes
2020-02-23T22:11:46 < Cracki> now I feel like chewing some sodium
2020-02-23T22:12:05 < emeb> just get a mouthful of drain cleaner
2020-02-23T22:12:30 < Cracki> fizzy
2020-02-23T22:13:19 < Cracki> minks in 60 fps https://www.youtube.com/watch?v=HLDjnJ04zhA
2020-02-23T22:13:47 < emeb> or you could just mix cola + mentos in your mouth
2020-02-23T22:14:14 < Cracki> I can bear the taste of cola but menthol needs to be eradicated
2020-02-23T22:14:34 < emeb> you can get fruit-flavored mentos

2020-02-23T23:18:07 < specing> Thorn: any launches soon?
2020-02-23T23:18:33 < Steffanx> i was more wondering if you recognized the disney crap Thorn :P
2020-02-23T23:19:01 < Thorn> specing https://spaceflightnow.com/launch-schedule/
2020-02-23T23:22:40 < englishman> Thorn: love my moka pot but got a single cup drip machine
2020-02-23T23:25:28 < BrainDamage> if you're willing to pay slightly extra
2020-02-23T23:25:30 < BrainDamage> https://img.freeauctiondesigns.com/caffecarpediem/812lqn6BJeL._SL1500_.jpg
2020-02-23T23:25:36 < BrainDamage> this one has a weighted valve on top
2020-02-23T23:25:47 < BrainDamage> it triggers on higher pressure than a normal moka
2020-02-23T23:25:48 < englishman> like anything else it wears out and you have to replace a small plastic part that costs half of what the entire thing costs
2020-02-23T23:25:55 < BrainDamage> so the taste is less bitter
2020-02-23T23:26:02 < BrainDamage> the oring?
2020-02-23T23:26:13 < BrainDamage> here it's sold for pennies
2020-02-23T23:26:18 < englishman> the plastic thing cracked
2020-02-23T23:26:27 < BrainDamage> the handle? also sold as replacement
2020-02-23T23:26:32 < englishman> it blew into the ceiling actually
2020-02-23T23:26:40 < englishman> no the thing in the middle you press on
2020-02-23T23:26:54 < BrainDamage> the lever for the top?
2020-02-23T23:27:03 < englishman> you have to give it a 1/3 twist to put it on
2020-02-23T23:27:08 < englishman> what?

2020-02-23T23:29:00 < BrainDamage> ahh, that's a mukka, it's a special type of moka
2020-02-23T23:29:06 < BrainDamage> it also has a push valve
2020-02-23T23:29:23 < BrainDamage> that one yes, you won't find cheap replacements
2020-02-23T23:29:29 < englishman> yeah. annoying
2020-02-23T23:29:33 < englishman> but also tasty
2020-02-23T23:29:55 < englishman> and tells you when it's done
2020-02-23T23:31:35 < BrainDamage> even a cheap moka you'll hear when it's done, because the noise changes abruptly when it runs out of water
2020-02-23T23:50:35 < zyp> speaking of pcb fabbing (two hours ago), can you get 6L or 8L for cheap at prototype qty nowadays?
2020-02-23T23:50:45 < zyp> with decent specs
2020-02-23T23:51:49 < zyp> whmm
2020-02-23T23:53:17 < zyp> I mean, I say decent but I'm not really thinking to do anything denser than 0.8mm bga, and I figure there's not much point doing six or more layers if you can't even do 0.8mm bga
2020-02-23T23:56:54 < karlp> Thorn: I love my moka pot personally.  wife doesn't like it though, she prefers french press
2020-02-23T23:57:22 < zyp> seeed can do 6L, but it's starting at like $300
2020-02-23T23:57:29 < zyp> compared to $5 for 2L and $50 for 4L
2020-02-23T23:58:50 < doomba> why is there such an increase in price for 6L ?
2020-02-23T23:59:10 < zyp> complexity?
2020-02-23T23:59:44 < doomba> i figured they just scale up the same process but maybe there's a lot i don't know about how pcb are made
2020-02-23T23:59:47 < zyp> idk, I'd expect the complexity difference from 2L to 4L to be bigger than 4L to 6L
--- Day changed Mon Feb 24 2020
2020-02-24T00:00:38 < karlp> I'd imagine it just hasn't (had to) streamline it's processes as much for smaller orders the way 2 (and recently 4) layer has been cut down 
2020-02-24T00:00:43 < doomba> you gotta be doing some pretty high density shit to require 6L i'd imagine
2020-02-24T00:01:41 < doomba> 2L was breaking my brain for that cluster controller thing, so i went to 4L... and then saw the prices
2020-02-24T00:02:11 < doomba> 4L is still reasonable but i went back to 2L and just made the board bigger lol
2020-02-24T00:02:13 < zyp> I mean, 2L is simple; etch, drill, surface, 4L is etch, apply prepreg, etch again, drill, surface
2020-02-24T00:02:30 < zyp> so I'd expect 6L to be another round of prepreg and etch
2020-02-24T00:02:54 < Thorn> 6l is at least $150 afaict
2020-02-24T00:03:01 < zyp> where?
2020-02-24T00:03:03 < karlp> I thought they did the layers separtaely and laminated. how else can you get blind/buried vias?
2020-02-24T00:03:19 < Thorn> jlcpcb iirc
2020-02-24T00:03:21 < zyp> karlp, drilling and plating in between the etching steps, I assume

2020-02-24T00:03:37 < zyp> Thorn, ah, was just about to fill in some stuff in their calc
2020-02-24T00:03:51 < zyp> heh
2020-02-24T00:04:29 < zyp> jlcpcb starts at $2 for 2L, $28 for 4L, $87 for 6L
2020-02-24T00:04:57 < zyp> that's not too bad
2020-02-24T00:05:43 < zyp> about $100 with ENIG
2020-02-24T00:06:39 < zyp> doomba, it's not so much about density as signal integrity
2020-02-24T00:07:08 < zyp> as soon as you start doing high speed shit you need reference planes
2020-02-24T00:07:19 < doomba> ah right
2020-02-24T00:07:32 < zyp> 4L gives you two signal layers
2020-02-24T00:07:39 < zyp> 6L gives you four
2020-02-24T00:07:48 < doomba> you mean having a differential pair on an inner plane that is shielded by planes above and below? essentially turning it into coax?
2020-02-24T00:07:54 < zyp> no
2020-02-24T00:08:28 < zyp> https://en.wikipedia.org/wiki/Microstrip
2020-02-24T00:08:50 < qyx> you can do microstrips on 2L too :p
2020-02-24T00:08:59 < BrainDamage> you can do striplines
2020-02-24T00:09:00 < karlp> you _can_
2020-02-24T00:09:07 < zyp> yeah, but 1.6mm to the reference plane results in super wide traces
2020-02-24T00:09:08 < karlp> you may not like the sizes and spacings required :)
2020-02-24T00:09:42 < BrainDamage> unlike microstrips a stripline is not quasi-tem
2020-02-24T00:09:46 < BrainDamage> so it has more bandwith
2020-02-24T00:10:04 < BrainDamage> because no mixed dielectric of pcb and air
2020-02-24T00:10:57 < zyp> also, with 4L if you put ground in two layers, you've only got two layers left for power, signals and footprints
2020-02-24T00:11:04 < zyp> gets crowded quickly
2020-02-24T00:11:49 < zyp> 4L is fine if you can do footprints and highspeed on top layer, ground on second, power on third and low speed signals on fourth
2020-02-24T00:11:57 < doomba> i'm noob so i just route shit however i want. use a diff pair calc for my usb 2.0 (even though i probably don't really need to) and fill the rest in with a ground trace
2020-02-24T00:12:03 < doomba> or a ground fill or whatever
2020-02-24T00:12:06 < qyx> I am super curious if pcie works on 2L :p
2020-02-24T00:12:25 < qyx> if I manage to get those damned onion things
2020-02-24T00:12:44 < zyp> https://bin.jvnv.net/file/EBXVH.png <- this design is built like that, although HS USB and 100Mb/s ethernet is not really that high speed
2020-02-24T00:13:06 < doomba> qyx: qyx  i'm holding a 2L pcie adapter thing in my hand right now
2020-02-24T00:13:37 < zyp> but I doubt the fpga shit I've got in mind would fit in 4L
2020-02-24T00:13:40 < doomba> there is a 35 pin FPC connector about 1cm away from the pcie m key where a nvme plugs in
2020-02-24T00:14:20 < qyx> whoa zyp no power-or on the backplane vbus output?
2020-02-24T00:14:22 < doomba> the pairs are very short. no more than 1cm

2020-02-24T00:14:43 < zyp> fanning out and routing 64-bit wide DDR3 probably needs several signal layers, even with the pin swap flexibility a fpga gives me :p
2020-02-24T00:26:32 < zyp> hmm, the jlcpcb 6L stackup looks a bit inconvenient
2020-02-24T00:28:01 < zyp> two cores, so layer distances are 0.1, 0.565, 0.127, 0.565, 0.1

2020-02-24T00:56:08 < zyp> I figured signal, gnd, signal, signal, gnd, signal, with power polygons in signal layers as needed
2020-02-24T00:57:18 < zyp> I'm also realizing that my >4L theory is not so deep, I assumed they only referenced the closest ground plane
2020-02-24T00:58:19 < zyp> but I guess it might be more correct to treat the inner layer signals as striplines, referencing two ground planes
2020-02-24T00:58:19 < BrainDamage> gnd or vdd is the same at least for signal integrity pourposes
2020-02-24T00:58:43 < BrainDamage> so you can just use all power planes
2020-02-24T00:59:04 < zyp> and now I'm confused as to how that fits together when two signal layers are sandwiched between two ground planes
2020-02-24T00:59:42 < BrainDamage> they both are striplines
2020-02-24T01:00:07 < BrainDamage> but unline gnd-signal-gnd-signal you have more crosstalk
2020-02-24T01:00:11 < zyp> https://jlcpcb.com/quote#/impedance <- even with this stackup?
2020-02-24T01:00:39 < zyp> the two inner layers are closer to each other than their respective ground plane
2020-02-24T01:01:08 < BrainDamage> in that case, you'll have minimal coupling to the opposite face
2020-02-24T01:01:18 < BrainDamage> that'll reduce crosstalk
2020-02-24T01:01:28 < zyp> how so?
2020-02-24T01:02:00 < BrainDamage> because the field intensity goes with 1/r
2020-02-24T01:02:09 < zyp> yes
2020-02-24T01:02:34 < BrainDamage> so it still couples with the face far away, but the interfering signal is further away
2020-02-24T01:02:45 < BrainDamage> so the crosstalk is significantly reduced
2020-02-24T01:02:56 < zyp> I think you misread me
2020-02-24T01:03:08 < BrainDamage> oh?
2020-02-24T01:03:24 < zyp> look at the bottom table on the page I linked to, I'm assuming ground in layer 2 and 5
2020-02-24T01:04:02 < zyp> layer 3 is 0.565mm away from layer 2 and 0.127mm away from layer 4
2020-02-24T01:04:28 < zyp> which means that the signal layers are coupling more to each other than their respective grounds
2020-02-24T01:05:02 < zyp> this is what's making me confused in the first place, why would they do it like this?
2020-02-24T01:06:18 < zyp> my original assumption was that I could think of layer 3 as a microstrip referenced to layer 2, since it would be close to layer 2 and far away from layer 4
2020-02-24T01:07:21 < zyp> e.g. if the layers were spaced something like 0.1mm, 0.1mm, 1.1mm, 0.1mm, 0.1mm
2020-02-24T01:07:32 < BrainDamage> that works
2020-02-24T01:08:02 < zyp> okay, so my original assumption holds, and the jlcpcb stackup is weird?
2020-02-24T01:08:49 < zyp> in that case, what's a sensible layer usage with their stackup?
2020-02-24T01:09:04 < BrainDamage> yes, I do consider it weird too
2020-02-24T01:11:28 < zyp> regarding using power planes as reference, how does that work out when you're switching layers?
2020-02-24T01:12:46 < BrainDamage> as long as you have sufficient amount of decoupling capacitors between the layers, it doesn't matter if you use vdd or gnd
2020-02-24T01:13:20 < BrainDamage> you can achieve this with a network of vias and decoupling caps
2020-02-24T01:13:25 < zyp> with ground planes as reference you stitch them with vias around the signal vias to minimize the disruption, but what when you're crossing from gnd as reference to vdd as reference?
2020-02-24T01:13:29 < zyp> stitch with caps?
2020-02-24T01:13:46 < BrainDamage> yes
2020-02-24T01:14:11 < zyp> hmm, I guess
2020-02-24T01:14:37 < zyp> I mean, yeah, the theory is simple
2020-02-24T01:14:56 < zyp> return path in reference ground matters for higher freqs, caps are shorts at higher freqs
2020-02-24T01:15:17 < BrainDamage> yes, make sure you have multiple paths of transmission
2020-02-24T01:15:29 < BrainDamage> because the field is not uniform otherwise
2020-02-24T01:15:44 < BrainDamage> and you'd have a char impedance jump
2020-02-24T01:15:58 < zyp> I think I'd still prefer to avoid referencing to anything but actual ground
2020-02-24T01:16:24 < zyp> https://bin.jvnv.net/file/KfWnp.png <- my power planes tend to look like this anyway
2020-02-24T01:17:24 < BrainDamage> that poor poe module
2020-02-24T01:17:29 < zyp> haha
2020-02-24T01:18:20 < zyp> anything fast enough that impedance matters tend to require multiple power rails
2020-02-24T01:19:02 < zyp> except simple rf stuff, and that's usually simple enough all rf paths can run on top layer

2020-02-24T03:09:58 < karlp> "not counting" means "see no changes in _CNT"?

2020-02-24T04:44:14 < upgrdman> wtf. super weird bug. i have a "volatile uint8_t command_buffer[32] = {0};" in one file, and "extern volatile uint8_t command_buffer[32];" in another file. if i swap them around, so the extern is in the opposite file, then when i sprinf() in a THIRD FILE THAT DOESNT USE THAT BUFFER, sprintf puts junk in my string.
2020-02-24T04:44:31 < upgrdman> guessing some sort of buffer overflow but not sure how that would trigger it

2020-02-24T08:29:16 < doomba> the number of components next to the usb-c connector indicates that

2020-02-24T13:30:44 < zyp> I wanna make a portable buildenv for workstuff (so my coworker can build my shit when I go on vacation in two weeks)
2020-02-24T13:31:54 < zyp> was thinking about making a docker container, but it seems like one of the build tools are only available for windows, and windows containers looks kinda too restricted to be useful
2020-02-24T13:33:25 < zyp> (the tool in question is the TI HET assembler or whatever you want to call it, it takes a .het file and generates .c/.h-files with data to load into the timer memory)
2020-02-24T13:34:23 < zyp> I don't wanna put the generated .c/.h files in git to avoid needing the tool
2020-02-24T13:35:01 < zyp> I figure an ugly but possibly workable solution would be running hetp.exe in wine
2020-02-24T13:35:40 < zyp> any better ideas?

2020-02-24T14:13:39 < zyp> hmm, looks like docker on windows might have improved since last I looked at it, gonna give it a try
2020-02-24T14:14:52 < zyp> docker has the advantage it's also easily scriptable

2020-02-24T14:17:13 < invzim> e.g a single instance of an sql database, in docker, with some kind of docker storage
2020-02-24T14:17:46 < invzim> so to change a single thing, i.g. a fault fix, the ops people would suddenly have to be docker experts in addition to sql experts
2020-02-24T14:18:05 < invzim> which is not really realistic
2020-02-24T14:18:26 < invzim> great for job security though :)
2020-02-24T14:25:35 < Cracki> was that an admin/sysops/devops person?
2020-02-24T14:26:10 < Cracki> every time I've had someone wanting to complicate things with virtualization of any kind, they wanted to take freedom away from others (developers) and hoard it for themselves
2020-02-24T14:30:14 < zyp> thing is, I'm the only C dev
2020-02-24T14:30:52 < zyp> I don't trust coworker to be able to debug the build env, so I want to make a package that just works
2020-02-24T14:33:29 < zyp> coworker does simulink stuff that shits out a pile of generated C code
2020-02-24T14:34:26 < zyp> so I wanna make something simple that takes the .zip of generated code in one end and gives out a finished .elf on the other end or so
2020-02-24T14:34:53 < zyp> because right now I'm what takes the .zip and gives back the .elf
2020-02-24T14:38:20 < invzim> Put something on a server and make it a tool_
2020-02-24T14:38:21 < invzim> ?
2020-02-24T14:43:10 < zyp> on what server?
2020-02-24T14:43:43 < invzim> have your colleague use a server as a user to get the elf
2020-02-24T14:44:10 < zyp> I mean, that's basically what I want to do, but instead of running it centrally somewhere I want to make it a portable thing that could be run locally
2020-02-24T14:44:56 < invzim> nah, you should put it in the cloud - scales better :)
2020-02-24T14:46:20 < zyp> I don't think so
2020-02-24T14:46:31 < Cracki> zip2elf as a service, charge per conversion :>
2020-02-24T14:47:02 < Cracki> can that simulink person operate ssh?
2020-02-24T14:47:27 < Cracki> set up some vm or whatever, somewhere, have them copy the zip over, run a shell script or sth, copy the elf back
2020-02-24T14:47:57 < Cracki> it doesn't have to be portable, it just has to run
2020-02-24T14:48:06 < invzim> you need jenkins!
2020-02-24T14:48:11 < zyp> I figure a cloud server that beats local hardware on performance isn't cheap, so it wouldn't make sense to run it continously to support a few builds now and then
2020-02-24T14:48:20 < Cracki> use local hw then
2020-02-24T14:48:40 < BrainDamage> using local hw has the benefit that the hw scales with the demand
2020-02-24T14:48:44 < BrainDamage> because one machine per dev
2020-02-24T14:48:46 < Cracki> the point of "cloud" is so you and only you have the secret sauce. if that's not a concern... no cloud
2020-02-24T14:50:53 < BrainDamage> now I wonder if using distcc on every machine might be worth it
2020-02-24T14:51:05 < BrainDamage> using lowest io and cpu prio so it doesn't bother the user
2020-02-24T14:52:24 < zyp> anyway, windows docker doesn't seem as bad as I thought, so it should be usable
2020-02-24T14:52:31 < zyp> now I just need to make a container image
2020-02-24T14:52:59 < invzim> in other news, dirtypcbs have shipped my acrylics - ordered 12th of feb
2020-02-24T14:53:30 < invzim> i.e. not very corona affected

2020-02-24T15:13:43 < Steffanx> Hows the lock down, BrainDamage  ?
2020-02-24T15:14:07 < Steffanx> I bet you have a real 
2020-02-24T15:14:08 < BrainDamage> supermarket well stocked and is as frequented as normal
2020-02-24T15:14:13 < Steffanx>  / proper mask
2020-02-24T15:14:44 < BrainDamage> cities with infected people instead went into panic and made the shelves empty
2020-02-24T15:14:55 < BrainDamage> ( even those not in full lockdown )
2020-02-24T15:15:21 < BrainDamage> I did ask out of curiosity, hand sanitizer is not available and surgical masks out as well
2020-02-24T15:15:36 < BrainDamage> and people selling either for 80 bucks on amazon
2020-02-24T15:16:04 < kakimir> future
2020-02-24T15:16:09 < kakimir> this is the new normal
2020-02-24T15:16:11 < Cracki> what's in hand sanitizer anyway. I know plain alcohol, ipa or sth, will dry out your skin so maybe there's a way to cook this up
2020-02-24T15:16:34 < BrainDamage> it's gelled alcohol and an hydrating agent
2020-02-24T15:16:43 < kakimir> ipa is the base part
2020-02-24T15:16:55 < kakimir> there can be some acetate something too
2020-02-24T15:16:58 < BrainDamage> you can diy gelled alcohol
2020-02-24T15:17:30 < BrainDamage> using calcium acetate, using eggshells and vinegar
2020-02-24T15:17:44 < zyp> Cracki, mine says mostly ethanol, some IPA the rest unspecified
2020-02-24T15:17:58 < BrainDamage> the hydration part, you can use a run out the mill beauty cream
2020-02-24T15:18:05 < zyp> like 75% ethanol, 5% IPA and 20% whatever
2020-02-24T15:18:05 < Cracki> heh

2020-02-24T15:18:54 < zyp> kakimir, to do what?
2020-02-24T15:19:00 < kakimir> only thing I come up with to CLE and ALE is invert-OR-invert
2020-02-24T15:19:12 < kakimir> see truth table zyp
2020-02-24T15:19:12 < Cracki> that picture looks like it should have some boxes in it but it's just some tables and some labels

2020-02-24T15:28:39 < kakimir> mask fashion
2020-02-24T15:29:05 < BrainDamage> that exists already
2020-02-24T15:29:28 < BrainDamage> some stylists are already selling branded version of masks for hundreds of bucks
2020-02-24T15:29:51 < kakimir> I want cyberfuturistic mask
2020-02-24T15:30:08 < kakimir> vanilla doesn't cut it
2020-02-24T15:31:06 < Laurenceb> I thought masks dont do anything?
2020-02-24T15:31:43 < Cracki> the simple ones don't do much
2020-02-24T15:32:14 < kakimir> simple ones are to keep anything bigger than squirrel out 
2020-02-24T15:32:45 < kakimir> or bearing balls
2020-02-24T15:32:58 < kakimir> *ball bearings
2020-02-24T15:33:17 < Cracki> they're better than a cloth in front of the mouth but worse than higher grade masks that actually close around the mouth and filter particles down to whatever size coronavirus is
2020-02-24T15:33:24 < kakimir> and keep sneezes in
2020-02-24T15:33:28 < kakimir> and coughs
2020-02-24T15:33:53 < Cracki> yes in hospitals they put them on sick ppl so they can't sneeze and cough on everything directly
2020-02-24T15:34:54 < Cracki> if you're lucky, the hospital's air conditioning sucks air away and uses good filters
2020-02-24T15:35:18 < BrainDamage> you need a full respirator with a sub-um filter if you want something effective
2020-02-24T15:35:31 < BrainDamage> and it's going to take a toll on breathing

2020-02-24T15:36:15 < BrainDamage> kakimir: you can get software that does logic simplifcation without resorting to do by hand
2020-02-24T15:36:23 < Cracki> kakimir, what you see there is to be understood as a torus, i.e. go off the map on one side, reappear on the other
2020-02-24T15:36:25 < kakimir> which one?
2020-02-24T15:36:32 < BrainDamage> for "low" amount of variables, you can do quine-mcluskey
2020-02-24T15:36:49 < BrainDamage> by low I mean up to 100 or so

2020-02-24T17:42:05 < bitmask_> the liquid started as 14% sulfuric acid, I boiled it from 700ml to 400ml (about 100mL of acid) I was going to sleep so I just stopped it there, I planned on going to like 200 mL but it was taking a while. the copper sulfate was saturated enough to start forming crystals as it cooled down and thats what I was left with.  I'll make some more since I have more copper metal and more solution in the glass as you can see in the pic. I
2020-02-24T17:42:05 < bitmask_>  just poured the liquid off into another jar and scraped out the crystals

2020-02-24T19:47:37 < englishman> Sébastien Boulanger Dorval n’a pas touché d’argent comptant pour les données dérobées. Selon nos sources, les acheteurs l’ont plutôt payé avec quelques milliers de dollars... en cartes-cadeaux d’épicerie et des restaurants Saint-Hubert.

2020-02-24T20:36:38 < invzim> kakimir: 
2020-02-24T20:37:09 < invzim> they have very sharp edges, and you will probably want a series resistor to dampen things - I learned this the hard way
2020-02-24T20:37:52 < kakimir> in what use?
2020-02-24T20:38:19 < kakimir> if you want more general use then HC
2020-02-24T20:38:47 < kakimir> this thing is running at 25Mhz
2020-02-24T20:38:54 < invzim> I just picked lvc because it fit nicely and it's 5v5 tolerant on input
2020-02-24T20:39:07 < kakimir> how long lines you had there?
2020-02-24T20:39:11 < kakimir> what use?

2020-02-24T20:40:24 < invzim> all works well, but I may put a resistor on some lines in a later rev to get rid of overshoot/ringing
2020-02-24T20:40:36 < zyp> went pretty well except one of the fucking installers kept getting stuck
2020-02-24T20:41:05 < zyp> turns out it embeds another installer for some third party shit and despite it running in headless mode, the second installer is not started in headless mode

2020-02-24T23:15:03 < kakimir> have you guise done a lot of logics?

2020-02-24T23:19:48 < kakimir> I know
2020-02-24T23:20:31 < zyp> you mean done as in actually designed shit with discrete logics?
2020-02-24T23:20:43 < kakimir> or virtual logics
2020-02-24T23:20:52 < kakimir> where same rules apply
2020-02-24T23:21:53 < zyp> I don't think I've done discrete logic since uni exercises
2020-02-24T23:22:06 < qyx> same here
2020-02-24T23:22:50 < qyx> I feel very ashamed if I have to use even a single logic gate
2020-02-24T23:23:06 < zyp> I put a cpld on a board once, but that was more for routing than logic
2020-02-24T23:23:30 < zyp> and then some fpga stuff, but that's stuff that's too large for discrete logic anyway
2020-02-24T23:23:52 < qyx> unrelated: some of you have been doing programmable switching power supplies
2020-02-24T23:24:14 < qyx> any successful outcomes documented?
2020-02-24T23:24:20 < zyp> not yet, but I want to on the fpga shit I'm thinking about
2020-02-24T23:24:58 < zyp> so IO banks can be programmed later
2020-02-24T23:24:59 < qyx> I need 5V in, 5-30V out, 100mA out max
2020-02-24T23:25:20 < zyp> i.e. boost?
2020-02-24T23:25:25 < qyx> lets say
2020-02-24T23:25:38 < qyx> it would be great if buck-boost, but I can live with boost only
2020-02-24T23:25:56 < qyx> also, idk how lab supplies are done, is there a LDO post-regulator?
2020-02-24T23:26:17 < qyx> with high PSRR or whatevere
2020-02-24T23:26:25 < zyp> depends how much you pay, I believe

2020-02-25T00:49:24 < Steffanx> Did you built it up on bread board yet kakimir  
2020-02-25T00:49:30 < kakimir> I won't
2020-02-25T00:49:34 < kakimir> it would be massive
2020-02-25T00:49:37 < Steffanx> Yes you will
2020-02-25T00:49:44 < Steffanx> Measure the delay
2020-02-25T00:49:57 < kakimir> why wouldn't I trust the datasheets?
2020-02-25T00:50:18 < Steffanx> Why would you trust yourself
2020-02-25T00:51:08 < englishman> remember that time kakitism refused to buy a $30 icestick and instead hand placed 3000 xor ics

2020-02-25T00:51:46 < englishman> thanks
2020-02-25T00:51:53 < englishman> I think that will work for something
2020-02-25T00:51:59 < englishman> will check spex later
2020-02-25T00:52:04 < kakimir> I think the bom cost of logics will be under 10$ even in low quantity

2020-02-25T00:57:31 < kakimir> stuff needs to be contained in small area
2020-02-25T00:57:42 < qyx> are you building a HF transmitter
2020-02-25T00:57:55 < kakimir> also 15cm of wire is like 1ns
2020-02-25T01:01:17 < kakimir> and I have total budget of 25ns
2020-02-25T01:01:36 < catphish> can i just rant for a moment about solicitors
2020-02-25T01:01:42 < kakimir> yes
2020-02-25T01:02:09 < catphish> why are they so lazy? and why are they so disinterested in work?
2020-02-25T01:02:50 < catphish> can they really earn so much money from reproducing standard forms that they have literally no interest in actual interesting potentially contentious work?
2020-02-25T01:04:06 < catphish> i have tried contacting 3 different solicitors about something, the responses varied between standard advice that a 5 year old could have googled, and "i'm semi retired and aren't taking on anything difficult"
2020-02-25T01:04:35 < catphish> that is all
2020-02-25T01:05:12 < catphish> i'm seriously about to be that idiot who represents himself, not because i want to, but because i can't find anyone else to give a shit about my case

2020-02-25T01:13:55 < Laurenceb> ooh catphish is here, you know about engines right?
2020-02-25T01:14:22 < Laurenceb> I've got pitting on the cam lobes of my car, any idea how bad that is?
2020-02-25T01:14:26 < catphish> Laurenceb: only just barely
2020-02-25T01:14:29 < Laurenceb> k
2020-02-25T01:14:45 < catphish> i know how my own cars work, but that's about it :)
2020-02-25T01:14:47 < Laurenceb> new camshaft is <£100 but its a pita to fit
2020-02-25T01:15:35 < Laurenceb> I'll reassemble it and see what happens...
2020-02-25T01:15:41 < catphish> fitting a new camshaft sounds like you'd need to completely disassemble the block/piston assembly, way beyond my knowledge
2020-02-25T01:15:57 < Laurenceb> I've dismantled the top to redo the common rail injection
2020-02-25T01:16:09 < Laurenceb> but yeah camshaft replacement is rather more fiddly
2020-02-25T01:16:13 < catphish> yeah, i suspect you know more than me at this point
2020-02-25T01:16:43 < Laurenceb> I've found people leaving the same sort of damage for some time on aero and motorbike engines
2020-02-25T01:17:11 < Laurenceb> no clear info on how quickly it deteriorates on car engines :S

2020-02-25T01:28:13 < zyp> uh, camshaft goes in the top, not in the block, right?
2020-02-25T01:28:26 < jly> well
2020-02-25T01:28:32 < jly> is it an OHC engine?
2020-02-25T01:28:50 < zyp> aren't most modern dinosaur engines?
2020-02-25T01:29:25 < zyp> my impression is that replacing a camshaft isn't really hard, you just need to make sure you don't fuck up the timing
2020-02-25T01:29:58 < jly> yeah that'd hurt 
2020-02-25T01:30:31 < jly> the uhhhmerikans like their pusrod V8s which have the camshaft in the engine block 
2020-02-25T01:30:34 < Laurenceb> sure its not too hard

2020-02-25T01:31:55 < Laurenceb> thats the issue

2020-02-25T08:47:47 < dongs> fuck that shit
2020-02-25T08:57:54 < jadew> winscp works for plain FTP too
2020-02-25T08:58:08 < jadew> so... what's the news on the plague?
2020-02-25T09:00:21 < jadew> fantastic... youtube has started feeding me recommendations in asian
2020-02-25T09:00:45 < jpa-> i'm getting package from lcsc today, if you want i can mail some virus samples to you jadew 
2020-02-25T09:01:02 < jadew> jpa-, thanks, but I've got my own
2020-02-25T09:01:51 < jadew> I figured that if I don't touch them for two weeks or so, it should be good

2020-02-25T09:07:02 < jpa-> yeah, i think an hour at 85°C wouldn't harm any parts (even electrolytics) and is still plenty above the 15 min @ 70°C that some googling tells to be enough for most viruses
2020-02-25T09:11:57 < antto> winscp
2020-02-25T09:12:11 < upgrdman> antto, tried it. works. ugly as fuck tho
2020-02-25T09:12:20 < antto> on linux, lxde's filemanage (PCManFM) can do it too
2020-02-25T09:12:49 < antto> which is convenient when you got LXDE already
2020-02-25T09:13:33 < antto> yeah, winscp ain't huge fun
2020-02-25T09:13:51 < antto> but crapdows sux in general so.. is that surprising
2020-02-25T09:15:20 < antto> my daplink programmer arrived btw, i got it to blink some blue LED and i could see it figured out what my chip is via openocd

2020-02-25T09:29:45 < upgrdman> anyone used stm32 usb-hs? can the mcu saturate usb-hs?
2020-02-25T09:29:54 < upgrdman> (480Mbps)
2020-02-25T09:31:13 < jpa-> upgrdman: i have used it, it gets quite close at least
2020-02-25T09:31:21 < upgrdman> cool
2020-02-25T09:31:42 < jpa-> on STM32H7 there is a DMA mode where the usb peripheral automatically fetches stuff from memory, but many USB libraries don't support it yet
2020-02-25T09:31:58 < upgrdman> hmm that's neat
2020-02-25T09:32:12 -!- m4ssi [~massi@host31-39-static.242-95-b.business.telecomitalia.it] has joined ##stm32
2020-02-25T09:33:16 < jpa-> without that it is slightly more CPU intensive, like 10-20% load with cpu at ~200 MHz
2020-02-25T09:34:20 < upgrdman> cool. i basically just want to shit all ADC samples out to USB, so that's fine. basically ADCs -> DMA -> memory, then USB <- DMA <- memory, so little cpu usage
2020-02-25T09:34:32 < jpa-> most important is actually the PC side - many usb libraries work like "submit request, receive reply, submit new request" and will end up wasting a millisecond or more between requests; but it is possible to pipeline multiple requests simultaneously, like fx2pipe and similar programs do
2020-02-25T09:34:45 < upgrdman> k
2020-02-25T09:35:56 < jpa-> but with internal ADCs.. that's like 5 MSps x 3 ADCs x 16 bits each, tops? so 30 MByte/s
2020-02-25T09:36:00 < jpa-> shouldn't be a problem
2020-02-25T09:36:10 < upgrdman> ya
2020-02-25T09:36:35 < dongs> you can queue bulk requests with libusb easily
2020-02-25T09:36:41 < dongs> the problem is that on windows libusb is absolute garbage
2020-02-25T09:37:07 < upgrdman> cdc vcp uses bulk transfers right?
2020-02-25T09:37:21 < jpa-> sure
2020-02-25T09:37:29 < upgrdman> i wonder if i can be lazy AF and just treat it like a UART, and shit 30MBps onto it
2020-02-25T09:37:49 < upgrdman> and hope that the serial port lib isn't retarded.
2020-02-25T09:37:49 < jpa-> the pc side driver for virtual com ports might not be up to it
2020-02-25T09:37:57 < upgrdman> but it probalby is ;)
2020-02-25T09:38:00 < upgrdman> ya
2020-02-25T09:38:03 < dongs> ugh dont uses CDC what the fuck dude
2020-02-25T09:38:07 < dongs> its not that hard to setup bulk transfers
2020-02-25T09:38:12 < dongs> for your adc shit
2020-02-25T09:38:22 < jpa-> yeah, it gets easier than dealing with com port numbers and what not
2020-02-25T09:40:17 < jpa-> also, just put the winusb descriptors in firmware and libusb is pretty nice on windows also
2020-02-25T09:40:27 < dongs> thats not the unnice part

2020-02-25T14:10:40 < englishman> you should be fine tomeaton17 but 17 is pretty old why not upgrade
2020-02-25T14:11:06 < karlp> probably because altium wants them to pay again?
2020-02-25T14:16:20 < zyp> tomeaton17, yeah, it works fine
2020-02-25T14:16:41 < zyp> I've got AD15 and I've collaborated on stuff made in AD18 without problems
2020-02-25T14:17:11 < zyp> you get a message when opening a design made in a newer version with a list of incompatible features you should avoid
2020-02-25T14:18:21 < aandrew> dongs: lol seriously you got banned?
2020-02-25T14:18:32 < invzim> I'm still on 17
2020-02-25T14:18:51 < zyp> invzim, who paid for it?
2020-02-25T14:19:02 < invzim> none of your damn business :)
2020-02-25T14:19:19 < zyp> if it's a pirated version, why don't upgrade? :p
2020-02-25T14:19:54 < zyp> I mean, the only thing that keeps me to AD15 is the fact I've got a legal license for it
2020-02-25T14:19:55 < invzim> I tried 18(?) but the gui changes/lib stuff pissed me off, and I had actual work to do so stuck with 17
2020-02-25T14:20:20 < invzim> work=stuff
2020-02-25T14:22:00 < invzim> have someone smarter than me made a cross-reference capacitance thingie for dc-bias?  I.e. 0805 10uF rated 16V=5uF@5V, if you need 5uF @3.3V - see A,B,C
2020-02-25T14:24:01 < zyp> does it really matter?
2020-02-25T14:25:03 < zyp> capacitors are wildly inaccurate anyway, if it's just for power I just slap on a decent bunch and call it a day
2020-02-25T14:25:30 < invzim> the fancy switchers are more picky, http://www.ti.com/lit/ds/symlink/tps63710.pdf
2020-02-25T14:25:41 < invzim> section 6.3 uses the term effective capacitance
2020-02-25T14:27:15 < zyp> sure, but even in the table you have like an order of magnitude of leeway
2020-02-25T14:29:35 < invzim> suure, but still - it would be nice if the capacitance value actually meant something
2020-02-25T14:30:17 < invzim> new to this switching business, so don't know what I can safely ignore yet
2020-02-25T14:31:41 < qyx> if they recommend 10u/16V/0805, they surely account for derating
2020-02-25T14:32:00 < aandrew> I'm also on 17
2020-02-25T14:32:16 < qyx> invzim: use ti webench to calculate your values
2020-02-25T14:32:17 < aandrew> zyp: you don't go past 17 if you're pirated because it calls home
2020-02-25T14:33:20 < zyp> I figure all versions do until they get coerced not to
2020-02-25T14:33:52 < zyp> it's not like pirates are gonna stop pirating just because they changed around stuff a bit
2020-02-25T14:35:03 < aandrew> agreed
2020-02-25T14:35:09 < aandrew> but pre-18, it wasn't calling home
2020-02-25T14:35:27 < zyp> my AD15 does, that's how it checks my license
2020-02-25T14:35:31 < karlp> so, aandrew's running pirate altium too?
2020-02-25T14:35:33 < aandrew> post-17 it is, and they haven't quite figured out where the snitch is
2020-02-25T14:35:52 < aandrew> karlp: actually I'm running paid altium, but I may revert back at any time which is why I'm sticking with what I know works
2020-02-25T14:36:02 < karlp> just teasing :)
2020-02-25T14:36:11 < aandrew> zyp: no, the license check/login isn't what I'm referring ot
2020-02-25T14:36:52 < aandrew> there's threads on sonsivri that describe a couple people getting bit, altium knows details of their work networks and such
2020-02-25T14:37:04 < BrainDamage> I make a point of running any important software on VM
2020-02-25T14:37:09 < aandrew> of course when altium comes knocking they just want you to buy it, but there is zero discount/wiggle room on list price
2020-02-25T14:37:15 < BrainDamage> if it breaks, I have a backup copy to restore
2020-02-25T14:37:52 < aandrew> BrainDamage: my altium only runs on VM because I only have windows VMs, but I don't know what will leak, and ESXi and other virtualization doesn't exactly hide the fact that your virtualizing, so I don't know what will get leaked there
2020-02-25T14:38:32 < zyp> you could always run a VM without networking
2020-02-25T14:38:34 < tomeaton17> englishman: okay thanks
2020-02-25T14:38:46 < BrainDamage> yup, my vm are without networking
2020-02-25T14:38:52 < aandrew> BrainDamage: yes that is one of the biggest reasons why I don't run windows without a VM
2020-02-25T14:39:05 < aandrew> fuck bit rot, forced updates and never being able to get back to a known good point
2020-02-25T14:39:07 < tomeaton17> I have the altium student advantage program so I can get the latest version but they don't
2020-02-25T14:39:46 < aandrew> zyp: yesish, but now my data is stuck on the VM (I know ESXi shared volders seem to still work, but I frankly don't want to dick around iwth it. let someone else figure it out)
2020-02-25T14:40:13 < aandrew> tomeaton17: yes, the student license pricing on altium is *very* nice
2020-02-25T14:40:18 < BrainDamage> you can have networking without a gateway
2020-02-25T14:40:20 < zyp> I mean, that's what I'd do if I ran pirate altium and were worried about it calling home
2020-02-25T14:40:29 < tomeaton17> Well I don't have to pay a thing
2020-02-25T14:40:31 < BrainDamage> then it won't be able to talk to the internet
2020-02-25T14:40:44 < BrainDamage> it'd just be an isolated iface
2020-02-25T14:41:04 < zyp> either just share the folder or run it on a separate network that only can reach where I want it to
2020-02-25T14:41:06 < tomeaton17> I'm not sure when my student licence is going to run out because I have had it for 4 years already :/
2020-02-25T14:41:35 < zyp> tomeaton17, do you have an account in altiumlive for that?
2020-02-25T14:41:46 < zyp> altiumlive shows license expiry
2020-02-25T14:43:49 < tomeaton17> zyp: I don't think I can see it says only group adminstrators can do that
2020-02-25T14:43:58 < tomeaton17> I guess I have the licence until they kick me out of the group
2020-02-25T14:44:17 < zyp> ah, right
2020-02-25T14:44:37 < zyp> in my case, I'm the administrator :)

2020-02-25T14:50:41 < zyp> subscription is a recurring payment, it gives you updates/new versions
2020-02-25T14:51:16 < zyp> once subscription expires, you get to keep access to the newest version available at expiry time
2020-02-25T14:52:22 < invzim> if the pricing wasn't insane, I wouldn't mind sending some dollars their way
2020-02-25T14:52:50 < zyp> that said, I believe there's multiple licensing schemes, so this is all subject to the deal you get
2020-02-25T14:53:07 < zyp> actually expiring licenses is probably also a thing
2020-02-25T14:53:13 < zyp> since there's a field for that in the UI
2020-02-25T14:53:50 < zyp> there's also offline licenses
2020-02-25T14:54:23 < tomeaton17> on the university computers they only have altium 16, I guess because its "only" $4k to upgrade to the newest version. having said that they are spending £400m on new engineering building and my lecturers are striking for 1 month smh
2020-02-25T14:54:47 < zyp> another place I worked gave me a computer with AD13, «what about login for it?» «you don't need that, it's got an offline license»

2020-02-25T15:12:22 < karlp> locm3 will just run desctructors then fall off the end and start executing whatever is in ram: https://github.com/libopencm3/libopencm3/blob/master/lib/cm3/vector.c#L93
2020-02-25T15:12:45 < karlp> which... I believe, will be the blocking hadnler just afterwrds, but....
2020-02-25T15:14:30 < karlp> you'll sometimes end up in _exit(), which has it's own set of loosely defined behaviour
2020-02-25T15:15:26 < karlp> https://github.com/eblot/newlib/blob/master/newlib/libc/sys/sysmec/crt0.S#L27 for isntance
2020-02-25T15:15:51 < veverak> interesting
2020-02-25T15:16:27 < karlp> or https://github.com/eblot/newlib/blob/master/newlib/libc/sys/arm/crt0.S#L404 if you prefer arm, just grabbed the first one, they're all ~same
2020-02-25T15:17:02 < veverak> so, basically, for the sake of course: "well, depends on the compiler and your setup"
2020-02-25T15:17:04 < karlp> you can also implement your own _exit for instance, if you want to .
2020-02-25T15:17:27  * veverak is preparing course and figured he could not answer this

2020-02-25T15:38:52 < jpa-> veverak: i've seen some platforms do a non-subroutine jump to main(), in which case the return would typically try to load value above the stack, usually above top of ram, crashing the cpu
2020-02-25T15:39:03 < jpa-> that has the benefit of saving a few bytes of stack
2020-02-25T15:40:28 < jpa-> (though on ARM it wouldn't work that way anyway, because LR is separate from stack)
2020-02-25T15:41:31 -!- con3 [~con3@165.255.111.10] has joined ##stm32
2020-02-25T15:42:03 < zyp> non-subroutine jumps on ARM are equivalent to a leaf call
2020-02-25T15:42:54 < zyp> in that sense, the startup code could stuff the address of _exit into LR
2020-02-25T15:43:57 < zyp> I guess if LR is uninitialized and the code eventually tries returning to the uninitialized value (0, I guess), it'd fault with INVSTATE

2020-02-25T19:51:45 < Steffanx> nevermind
2020-02-25T19:51:47 < Steffanx> then
2020-02-25T19:52:05 < jadew> if you're asking if I'm the creator of a new channel (IRC channel?), then the answer is no
2020-02-25T19:52:41 < jadew> is that what you were asking? cuz the channel thing threw me off
2020-02-25T19:52:51 < jadew> didn't know what kind of channel to think about
2020-02-25T19:53:58 < jadew> BrainDamage, so what's the situation like? does it seem like it's getting better or worse?
2020-02-25T19:54:09 < Steffanx> lol no. Some always called me Dad (of ##stm32). Now you seem to be worried about your fellow ircers, worried like a dad. > you are the new dad.
2020-02-25T19:54:42 < jadew> some of the new cases in Europe have been started by people in that region, which seems to indicate that it might not be localized just to that region
2020-02-25T19:54:57 < jadew> ah! got it
2020-02-25T19:55:25 < jadew> well, the situation there seems really sketchy and he said he's 50 km away from the epicenter
2020-02-25T19:55:29 < jadew> that's not very far
2020-02-25T19:56:12 < jadew> the health ministry had a press conference last night
2020-02-25T19:57:05 < jadew> everyone coming from Italy is supposed to stay in 14-day self isolation, and those coming from the affected regions are committed to real quarantine
2020-02-25T19:57:29 < jadew> disobeying that leads to prison time

2020-02-25T19:59:57 < doomba> "self isolation"
2020-02-25T20:00:00 < doomba> only the italians right?
2020-02-25T20:00:06 < Steffanx> that is.. romanian helath ministry?
2020-02-25T20:00:15 < jadew> no, everyone coming out of Italy
2020-02-25T20:00:24 < jadew> Steffanx, yeah
2020-02-25T20:01:00 < jadew> worst part about this is that the people who decided to come home were able to do that
2020-02-25T20:01:21 < jadew> what kind of job someone has to have to be able to just leave...
2020-02-25T20:01:51 < jadew> meaning that if things go south, we'll also have a bunch of thieves on our hands
2020-02-25T20:02:03 < jadew> that we didn't have last week
2020-02-25T20:02:07 < BrainDamage> jadew: numbers increasing slowly, but that's expected, there's mass testing and incubation period is ~2 weeks
2020-02-25T20:02:24 < BrainDamage> so even if no new contagions happen, there's still a few that are infected and don't show symptoms
2020-02-25T20:02:59 < jadew> right, are there talks about extending the quarantined region?
2020-02-25T20:03:57 < jadew> I think I'll install a CB radio on my car
2020-02-25T20:03:58 < BrainDamage> no, that's pending until the patient 0 is discovered
2020-02-25T20:04:06 < BrainDamage> otherwise it's pointless
2020-02-25T20:05:44 < Steffanx> Will you also install spikes on the front jadew?
2020-02-25T20:05:48 < Steffanx> Get a machete?
2020-02-25T20:06:03 < Steffanx> sawed off shotgun?
2020-02-25T20:06:12 < jadew> already have a machete - used it to chop the christmas
2020-02-25T20:06:34 < jadew> completely forgot about that, since it wouldn't be my first weapon of choice
2020-02-25T20:07:06 < Steffanx> Isnt it the weapon to have when the zombies attack?
2020-02-25T20:07:22 < jadew> maybe, but when people attack, other stuff might be more effective
2020-02-25T20:07:31 < jadew> like a heavy wrench
2020-02-25T20:07:40 < Steffanx> Corona doesnt seem to be too effective atm
2020-02-25T20:07:57 < jadew> took out china's economy
2020-02-25T20:08:02 < jadew> that's pretty effective
2020-02-25T20:08:23 < Steffanx> That's only temporarily.
2020-02-25T20:08:49 < jadew> we'll see how many people are still going to buy stuff from aliexpress once this is over
2020-02-25T20:09:01 < jadew> or anything that reads "made in china"
2020-02-25T20:09:07 < Steffanx> me
2020-02-25T20:09:47 < qyx> are you making some food reserves?
2020-02-25T20:09:56 < jadew> me too, but I'm willing to bet that their sales are going to go down by at least 50%

2020-02-25T20:23:29 < qyx> the level of dumbness here is extraordinary high now

2020-02-25T20:24:23 < Cracki> people can manage to disinfect stuff.
2020-02-25T20:24:57 < zyp> slow mail alone should be plenty
2020-02-25T20:25:04 < Cracki> the chinese are now mostly struck down because of the quarantine and "house arrest", which keeps workers from their work, and people off the streets (public transport very affected)
2020-02-25T20:25:18 < jadew> yeah, I think slow mail is the answer
2020-02-25T20:26:24 < Cracki> say mortality is 10%. simple work isn't affected, too many replaceable cogs out there. high tech will be affected because bus factor.
2020-02-25T20:27:07 < Cracki> this won't kill society or most areas of economy, it may put a temporary damper on it

2020-02-25T20:32:30 < zyp> jadew, not statistically significant

2020-02-25T20:33:42 < jadew> ah, that is true
2020-02-25T20:34:13 < Cracki> coronavirus compared to swine flu, looks similar in growth, except he didn't align them by data but by "day 1" https://youtu.be/6dDD2tHWWnU?t=155
2020-02-25T20:36:20 < jadew> Cracki, it shows how much more virulent this one is
2020-02-25T20:36:33 < Cracki> uh I disagree
2020-02-25T20:36:36 < Cracki> looks comparable to swine flu
2020-02-25T20:36:43 < Cracki> apart from the arbitrary "day 1" offsets
2020-02-25T20:36:47 < jadew> except it started ramping up, much much faster
2020-02-25T20:37:08 < Cracki> and the data for coronavirus so far suggests that the chinese are "plateauing"... for now
2020-02-25T20:37:08 < jadew> ah, you don't think day 1 is correctly established
2020-02-25T20:37:10 < jadew> fair point
2020-02-25T20:37:29 < Cracki> they pull 'day 1' out of their asses
2020-02-25T20:37:44 < Cracki> everything before the takeoff is just noise
2020-02-25T20:38:06 < Cracki> takeoff is when it is out of containment

2020-02-25T21:09:26 < jadew> at least once
2020-02-25T21:09:54 < jadew> I was referring to the long hair dude

2020-02-25T21:11:15 < jpa-> no-one wears swimsuits in sauna
2020-02-25T21:11:20 < jpa-> towel maybe

2020-02-25T21:12:00 < jadew> I went to such a sauna myself
2020-02-25T21:12:18 < Steffanx> i heard jpa- doesnt sauna anyway, so he cannot know what a sauna is like
2020-02-25T21:12:34 < jpa-> Steffanx: doesn't stop me from planting hidden cameras in saunas
2020-02-25T21:13:27 < Steffanx> true, pervert.
2020-02-25T21:13:54 < jpa-> i wouldn't call other people that, considering what you usually do in your bedroom..
2020-02-25T21:13:58 < jadew> I always thought a sauna is a great place to have sex
2020-02-25T21:14:01 < jadew> if it wasn't for the germs
2020-02-25T21:14:14 < jpa-> germs?
2020-02-25T21:14:22 < jadew> you know... from people

2020-02-25T21:48:36 < kakimir> solder doesn't just smell like that anymore
2020-02-25T21:49:06 < kakimir> maybe part of it is that iron is not 400C constant

2020-02-25T22:18:00 < Thorn> the reason I chose it over sht3x was lower min Vdd (important for coin cell power)

2020-02-26T02:09:27 < dongs> has anyone ever worked with solar -> lipo charger ICs
2020-02-26T02:09:32 < dongs> im wondering how they handle the large voltage drop
2020-02-26T02:09:38 < dongs> i.e. shit like BQ24210
2020-02-26T02:09:47 < dongs> from 12-16V solar array down to 3-4V
2020-02-26T02:09:56 < dongs> there's no way to do it without heating up if its linear?
2020-02-26T02:09:59 < dongs> or is there some magic im missing
2020-02-26T02:10:38 < Thorn> I've no idea about solar or lipo but there're many switch mode bq24/25xxx parts
2020-02-26T02:10:45 < kakigate> you sound like me dongs
2020-02-26T02:10:47 < zyp> wouldn't it be switching?
2020-02-26T02:10:59 < dongs> zyp, 24210 is defnitely linear, there's no coil
2020-02-26T02:11:01 < dongs> Thorn: yes, i know
2020-02-26T02:11:06 < zyp> looking
2020-02-26T02:11:09 < dongs> but I see linear parts being recommended and shit.
2020-02-26T02:12:10 < dongs> like it has 18V max and like 20V absmax v_in
2020-02-26T02:15:37 < emeb> zyp: worked through the #exactsteps for that litex vexriscv project - was able to build it for my ULX3S board
2020-02-26T02:15:59 < emeb> even loaded it up on the hardware.
2020-02-26T02:16:01 < dongs> 60C/W for the package... 16-4)*0.8A = like ~10W so that'd be bullshit, assuming the drop heats up like this
2020-02-26T02:16:07 < zyp> dongs, 9.2.1 is talking about «A solar panel with VOC = 6 V…»
2020-02-26T02:16:09 < emeb> but haven't figured out how to load the firmware yet.
2020-02-26T02:16:19 < dongs> zyp yeah but why have 20V in if youre gonna dick around wiht 5V
2020-02-26T02:16:22 < dongs> my panel is like 12-16V
2020-02-26T02:16:36 < zyp> to account for varying shit
2020-02-26T02:16:51 < dongs> so I shjould just use switching charger and fuck off right?
2020-02-26T02:17:01 < zyp> probably
2020-02-26T02:17:05 < zyp> emeb, cool
2020-02-26T02:18:04 < zyp> I've done some more reading up on how to do DDR3, starting to get an idea of the whole picture now
2020-02-26T02:18:04 < emeb> zyp: was pretty brainless - just followed the example. Had to tweak some of the target files because my board has a different FPGA (larger than the example)
2020-02-26T02:18:40 < zyp> I think you can override that with some flags to the build script
2020-02-26T02:18:57 < dongs> is this opensores veriblog thing
2020-02-26T02:19:06 < zyp> dongs, even better, it's python
2020-02-26T02:19:09 < zyp> :D
2020-02-26T02:19:12 < dongs> fucking disgusting.
2020-02-26T02:19:27 < emeb> zyp: perhaps so, but figuring out the flags is harder than just tweaking the target scripts
2020-02-26T02:19:37 < zyp> there's a --help :)
2020-02-26T02:19:48 < emeb> heh
2020-02-26T02:19:53 < emeb> too easy
2020-02-26T02:20:05 < emeb> anyway - didn't take much effort
2020-02-26T02:20:19 < emeb> trouble now is that I'm not sure how to load the firmware
2020-02-26T02:20:40 < emeb> the example talks about using lxterm to send it over serial port
2020-02-26T02:21:25 < emeb> but the ULX3S board uses some funky FTDI serial chip to emulate JTAG and after it loads the bitstream the serial device /dev/ttyUSB0 disapears
2020-02-26T02:21:32 < emeb> so lxterm has nothing to connect to.
2020-02-26T02:21:38 < zyp> I haven't looked that far into it since I don't have hardware yet
2020-02-26T02:22:07 < emeb> I assume this would be less complicated on hardware that has separate JTAG and serial ports
2020-02-26T02:22:08 < dongs> hey whats the part# for that smt ddip switch
2020-02-26T02:22:52 < dongs> is this shit made with kikecad

2020-02-26T02:25:34 < dongs> i have an assembly job with these and i had to buy from japscam site http://akizukidenshi.com/catalog/g/gP-08928/
2020-02-26T02:25:38 < zyp> emeb, I also dug out my icestick today, instanced a SoCCore with a UARTWishboneBridge, figuring out how this stuff actually fits together
2020-02-26T02:26:08 < zyp> apparently that alone consumes around half of the 1k fpga on the icestick :p
2020-02-26T02:26:32 < emeb> zyp: yeah  - that fpga is pretty small
2020-02-26T02:27:04 < emeb> zyp: did you see this? https://github.com/emeb/icestick_6502
2020-02-26T02:27:25 < zyp> cool
2020-02-26T02:28:17 < dongs> what does it do
2020-02-26T02:28:32 < zyp> I've started thinking I want to do a usb core
2020-02-26T02:29:28 < emeb> dongs: it's just a demo design that runs a soft 6502 core on a tiny FPGA to blink some lights and echo serial.
2020-02-26T02:30:12 < zyp> I've used a bunch of different usb cores from the software side, so it'd be interesting to see it from the other side too
2020-02-26T02:30:23 < emeb> zyp:  there have been a few different USB cores built on lattice parts lately. I guess that FOMU thing does one.
2020-02-26T02:30:32 < zyp> yeah, I'm aware
2020-02-26T02:30:34 < dongs> oh no the jappu dip switch is 1.27mm pitch
2020-02-26T02:31:10 < emeb> I built a little UP5K board last year and pinned out a USB socket. haven't really done much with it yet.
2020-02-26T02:31:11 < zyp> but I'm not looking for a core to use, I'm looking to write a core to learn the details about usb that I don't know yet :)
2020-02-26T02:31:18 < emeb> of course
2020-02-26T02:31:43 < zyp> got a project page for that?
2020-02-26T02:32:09 < zyp> or pics?
2020-02-26T02:32:25 < dongs> https://www.ctscorp.com/wp-content/uploads/218.pdf ok that works
2020-02-26T02:32:37 < emeb> Hmm... I don't think I ever did a page for that...

2020-02-26T02:57:09 < Thorn> that one
2020-02-26T02:57:14 < zyp> ATM90E32AS?
2020-02-26T02:59:55 < Laurenceb> https://www.imdb.com/title/tt8195518/
2020-02-26T03:00:07 < Thorn> this is a 3 phase one, that one was single phase iirc
2020-02-26T03:00:48 < zyp> well, I don't know which one you refer to, this is the one I used for my power meter board
2020-02-26T03:01:19 < Thorn> finally a movie Dr. Blaxter can relate to
2020-02-26T03:01:36 < Laurenceb> they made a film about doomba
2020-02-26T03:03:47 < doomba> oh yeaaa cuck. i watched it
2020-02-26T03:03:59 < doomba> it was an interesting movie
2020-02-26T03:05:02 < doomba> and a very good example of how (((hollywood))) changes narratives by redefining language
2020-02-26T03:05:49 < doomba> it also really makes one think about the power of memes
2020-02-26T03:06:28 < doomba> what was "cuck" before this movie? could it have been carl the cuck?
2020-02-26T03:07:31 < doomba> and then the most egregious stereotypes were simply flipped around to the "alt-right" and labeled "cuck"
2020-02-26T03:10:34 < doomba> what was most confusing about the movie, i thought, was why he went on the killing rampage
2020-02-26T03:11:37 < doomba> why not embrace the fame of being a porn star and turn it into a lasting career?
2020-02-26T03:11:53 < doomba> he could have been running his own studio in only a few years
2020-02-26T03:11:58 < dongs> Thorn: the $20 or something one?

2020-02-26T04:26:02 < kakimir> vaccine
2020-02-26T04:26:13 < jadew> or they stopped tracking

2020-02-26T04:35:33 < jadew> quick look at the data from the video, if you pay attention to the numbers, you'll see that it's more than 4 times deadlier than the swine flu
2020-02-26T04:35:43 < jadew> and has the potential to infect a lot more people

2020-02-26T12:46:48 < jadew> what that graph tells us is that it kills 3 times as many people as swine flu, in the same amount of time
2020-02-26T12:50:18 < dongs> which one is which
2020-02-26T12:50:22 < dongs> wheres the 2019 thing
2020-02-26T12:50:32 < jadew> CoV-2 is the 2019 one
2020-02-26T12:50:36 < dongs> oh
2020-02-26T12:50:41 < jadew> CoV-1 is the original SARS
2020-02-26T12:50:47 < dongs> whats 250
2020-02-26T12:50:49 < dongs> days?
2020-02-26T12:50:51 < jadew> days
2020-02-26T12:50:54 < jadew> yeah
2020-02-26T12:51:01 < dongs> you should add some legend to your opensores faggot graph
2020-02-26T12:51:06 < dongs> so its redable :p
2020-02-26T12:51:15 < jadew> yeah, I should name the axis :)
2020-02-26T12:51:36 < jadew> these are the infections (also log scale): http://5.12.44.107/stuff/cov-infections-log.png
2020-02-26T12:52:08 < jadew> I expect it to pick up again, because that flattening at the end is due to the chinese, but other places are picking up
2020-02-26T12:54:24 < jadew> I'm gonna go make some tea

2020-02-26T13:05:26 < invzim> with 0.6 it seems ok and looks like it will fit ok with the 3d model
2020-02-26T13:05:34 < invzim> what did you use for your production?
2020-02-26T13:09:28 < invzim> pcbcart just gave me scheduled completion 2020-03-05 for order placed 2020-01-10, so seems like CN is indeed getting back to business
2020-02-26T13:09:42 < invzim> pretty sure !china will not 'recover' that fast
2020-02-26T13:12:17 < jadew> I wonder if they would share the vaccine if they made one
2020-02-26T13:12:50 < invzim> I'm sure they would be happy to sell it
2020-02-26T13:13:01 < jadew> even to competing countries?
2020-02-26T13:13:43 < karlp> of course.
2020-02-26T13:13:51 < karlp> can't make any money selling shit if the rest of the world is dead
2020-02-26T13:14:40 < jadew> yeah, but if only competing markets are dead, then you make more

2020-02-26T15:36:17 < Mangy_Dog> i hear dying is bad
2020-02-26T15:36:21 < Cracki> or just vaccines
2020-02-26T15:36:22 < Mangy_Dog> and you start to smell after a while
2020-02-26T15:36:22 < jadew> today I woke up with a runny nose and a sore throat :P

2020-02-26T15:38:16 < Cracki> did you try turning it off and on again
2020-02-26T15:38:33 < Mangy_Dog> its about computerless flashing
2020-02-26T15:39:01 < Cracki> that's easy, instead of in front of a webcam you go in the park
2020-02-26T15:39:26 < Cracki> sounds like you want a microcontroller to perform SWD on another
2020-02-26T15:39:50 < Cracki> I'd take a raspi + stink dongle and be done with it :P

2020-02-26T15:40:08 < jadew> heard that news several times already
2020-02-26T15:40:30 < jadew> the CDC advises all US citizens to prepare for the outbreak
2020-02-26T15:40:41 < jadew> because it's coming
2020-02-26T15:40:59 < BrainDamage> well, the main issue is the burden on the health system
2020-02-26T15:41:05 < jadew> yep
2020-02-26T15:41:13 < BrainDamage> it'd be fun in the usa, with all the price gouging they have
2020-02-26T15:41:14 < jadew> so your best bet is not to get infected
2020-02-26T15:41:26 < jadew> because if you do and need help, you're screwed
2020-02-26T15:41:32 < BrainDamage> I bet insurances are already rising prices
2020-02-26T15:41:38 < Cracki> fuuuk muricans and their price gouging
2020-02-26T15:41:59 < jadew> Cracki, only the good americans get to live
2020-02-26T15:42:02 < Cracki> read an article, someone suspected he got it, so he went to a hospital to get tested, he's negative but they slammed him with a $3000 bill
2020-02-26T15:42:11 < karlp> Cracki: raspi it self is enough, can bitbang the gpios.
2020-02-26T15:42:23 < jadew> Cracki, hah
2020-02-26T15:42:41 < jadew> that's a good way to keep people away from hospitals
2020-02-26T15:42:53 < Cracki> it fucking is
2020-02-26T15:43:02 < Cracki> i'd rather spread the shit and die than be slapped with that bill
2020-02-26T15:43:09 < jadew> haha
2020-02-26T15:43:19 < jadew> I bet a lot of people feel the same way
2020-02-26T15:43:29 < Cracki> they can enjoy the consequences they create
2020-02-26T15:43:33 < jadew> in here the test is about $250
2020-02-26T15:43:48 < jadew> if you do it out of your own will
2020-02-26T15:43:53 < Cracki> same around here, but health insurances agreed to cover it
2020-02-26T15:44:05 < jadew> if you go to the hospital with symptoms, it's free
2020-02-26T15:44:08 < Cracki> and if you have symptoms or suspect that you may be infected, not for fun
2020-02-26T15:45:15 < Cracki> the health system in murica is one of the reasons I'd hate to move there
2020-02-26T15:45:32 < jadew> I've been wondering what would be the best thing to invest in, to stay financially safe in case the worst happens
2020-02-26T15:45:43 < jadew> not for this particular case, but in general
2020-02-26T15:45:47 < BrainDamage> morgues
2020-02-26T15:45:48 < Cracki> health insurance payments are so high, you're better off just stuffing it in a pillow
2020-02-26T15:45:52 < jadew> lol BrainDamage 
2020-02-26T15:45:57 < Cracki> invest in biotech
2020-02-26T15:46:39 < BrainDamage> remember that your money is only as worth as the economy
2020-02-26T15:46:42 < Cracki> >trump administration requesting 2.5 billion to fight the outbreak
2020-02-26T15:46:51 < jadew> BrainDamage, exactly
2020-02-26T15:46:57 < Cracki> guess what, border control could have helped :>
2020-02-26T15:47:03 < jadew> let's say 30% of the population died this year and you somehow survive - what's going to be in demand afterwards?
2020-02-26T15:47:24 < Cracki> for a _very_ brief period afterwards: digging equipment
2020-02-26T15:47:31 < jadew> haha
2020-02-26T15:47:47 < Cracki> if 30% die, you won't cremate them, you'll dump them in pits with gasoline on top
2020-02-26T15:47:50 < jadew> I think they just use excavators for that
2020-02-26T15:48:08 < jadew> yeah, you'd have mass graves
2020-02-26T15:48:14 < karlp> if 30% of populations  die, you're no longer going to be worried abotu how the stock market is doing.
2020-02-26T15:48:16 < jadew> those are easier to make tho
2020-02-26T15:48:26 < Cracki> we have big open pit mines around here. certainly large enough to make 30% of the population disappear into
2020-02-26T15:48:28 < karlp> like braindamage said...
2020-02-26T15:48:38 < jadew> karlp, exactly, so what would it be useful to own?
2020-02-26T15:48:55 < jadew> what would be in demand in that scenario?
2020-02-26T15:48:57 < karlp> depends how much of a prepper you want to be.
2020-02-26T15:49:08 < karlp> to me, you're way to far into the whatif territory
2020-02-26T15:49:26 < karlp> chances of being in that 30% are farrr higher than chances of guessing the right valuables to hoard for teh other side
2020-02-26T15:49:27 < Cracki> get replacement parts for all your high tech devices
2020-02-26T15:50:26 < Cracki> imagine removing 1 in 3 people in every company, factory, public service building, ...
2020-02-26T15:50:28 < jadew> Cracki, wouldn't there be a surplus of that already?
2020-02-26T15:50:44 < jadew> we'd have 30% more stuff than we needed
2020-02-26T15:50:54 < Cracki> no, it'll get bought up by those that come first
2020-02-26T15:51:10 < Cracki> you'd have buffers, but production still needs some workers
2020-02-26T15:51:38 < jadew> the economy would definitely shrink
2020-02-26T15:51:49 < Cracki> I'm saying everything will be depressed by 30% but anything that requires exceptional people, high iq or very skilled, is gonna get hit harder
2020-02-26T15:52:08 < jadew> right, because they're more difficult to replace
2020-02-26T15:52:33 < Cracki> because if you're a company that has one brainiac, you have a 30% chance losing that brainiac that drives your company
2020-02-26T15:52:49 < Cracki> you can keep going for a bit on what you have, but you'll need a new brainiac
2020-02-26T15:53:16 < BrainDamage> the coronabus factor
2020-02-26T15:53:40 < Cracki> it's "noisy". you also have a 70% chance of still having that brainiac, and if you keep the brainiac, you're better off than those that definitely eat the 30% loss
2020-02-26T15:54:30 < BrainDamage> a company has more than one key individual though
2020-02-26T15:54:37 < Cracki> right
2020-02-26T15:54:41 < jadew> not startups
2020-02-26T15:54:50 < Cracki> I'm thinking academic research
2020-02-26T15:54:53 < BrainDamage> startups are even worse
2020-02-26T15:55:06 < Cracki> eh startups are a numbers game too
2020-02-26T15:55:28 < BrainDamage> in a startup you're either a wage slave or someone with the know-how to make it run
2020-02-26T15:55:43 < BrainDamage> generally the founding members are those that make it or kill it
2020-02-26T15:56:02 < jadew> Cracki, with a 30% death rate, your business with one brainiac, that isn't you, has only 10% chances of survival
2020-02-26T15:56:07 < jadew> because you could also die
2020-02-26T15:56:25 < jadew> oh, wait, wrong math
2020-02-26T15:56:52 < BrainDamage> it's simple, if you assume 30% uncorrelated risk it's 0.3^n
2020-02-26T15:56:53 < jadew> 50%
2020-02-26T15:56:59 < BrainDamage> where n is number of key individuals
2020-02-26T15:57:03 < Cracki> anyway, it's not gonna be 30% and 9-10% only in areas that are as uncoordinated as china was in the early stages where it spread unhindered
2020-02-26T15:57:15 < BrainDamage> sorry, (1-0.3)^n
2020-02-26T15:57:21 < BrainDamage> that's survival rate
2020-02-26T15:57:25 < jadew> BrainDamage, yeah
2020-02-26T15:57:36 < Cracki> the dungeon master rolls your dice
2020-02-26T15:57:39 < jadew> it works out to 49% for owner + key monkey
2020-02-26T15:58:25 < karlp> you're still calculating with this pretty wild "30% of the world is going to die"
2020-02-26T15:59:38 < Cracki> lol vaccine "tests will get underway by the end of april"
2020-02-26T16:01:20 < Cracki> 78k infected chinese is still only 1 in 18000
2020-02-26T16:01:52 < jadew> Cracki, so far and as far as we know
2020-02-26T16:02:03 < jadew> karlp, it's an interesting thought experiment
2020-02-26T16:02:22 < jadew> apocalyptic TV shows kill like 95% of the population
2020-02-26T16:02:23 < Cracki> for hubei: 65k/58M = ~1 in 900
2020-02-26T16:02:33 < jadew> I'm being generous here
2020-02-26T16:02:42 < Thorn> Russia testing 5 prototype vaccines. chance of outbreaks increasing https://lenta.ru/news/2020/02/26/rastet/  #corona32
2020-02-26T16:03:20 < jadew> karlp, also, it's not impossible to happen
2020-02-26T16:03:36 < jadew> consider something that spreads like the ncov, but is as deadly as ebola
2020-02-26T16:04:08 < jadew> ...and turns you into a zombie once you die
2020-02-26T16:04:21 < BrainDamage> the zombie part is unphysical
2020-02-26T16:04:36 < BrainDamage> because you need energy to operate muscles
2020-02-26T16:04:51 < jadew> BrainDamage, actually, it appears that zombies are based on the rabies disease
2020-02-26T16:05:09 < Cracki> your body can consume its own flesh
2020-02-26T16:05:10 < BrainDamage> rabies leave you very much alive
2020-02-26T16:05:24 < BrainDamage> at least for a while
2020-02-26T16:05:24 < jadew> BrainDamage, yeah, but it affects your nervous system
2020-02-26T16:05:41 < jadew> which is why animals that are infected with it behave strangely
2020-02-26T16:05:43 < Cracki> is the mangy dog done eating yet
2020-02-26T16:06:11 < jadew> it's literally a disease that eats your brain
2020-02-26T16:06:45 < jadew> and can make you violent
2020-02-26T16:07:00 < karlp> I'm not really convinced it _is_ an interesting through experiment though, that way lies prepping and madness :)
2020-02-26T16:08:18 < jadew> well, prepping is not bad
2020-02-26T16:08:36 < jadew> you should always be prepared for something bad to happen
2020-02-26T16:08:45 < jadew> natural disaster, plague, etc
2020-02-26T16:08:58 < jadew> I can't think of any of my parents that didn't live through at least one such incident
2020-02-26T16:09:13 < jadew> parents and grandparents
2020-02-26T16:10:10 < karlp> having more than 24hours food in the house? good idea, having a bunker and a plan on which valuables to hoard and store based on what apocolypse is falvour of the week? madness.
2020-02-26T16:10:40 < jadew> karlp, I'm thinking about valuables in the sense of business opportunities
2020-02-26T16:10:51 < jadew> there might be something that could be profitable both now
2020-02-26T16:10:54 < jadew> and after such an event
2020-02-26T16:10:59 < jadew> that's a good business to have
2020-02-26T16:11:06 < Cracki> murican biotech and medical.
2020-02-26T16:11:15 < jadew> probably, yeah
2020-02-26T16:11:32 < Cracki> they squeeze 3k out of a dumb schmuck who thought he could trust a hospital
2020-02-26T16:11:35 < Cracki> you want those 3k in your pocket
2020-02-26T16:11:50 < jadew> I agree
2020-02-26T16:12:10 < jadew> if the world is unfair, you want to be on the side that comes ahead
2020-02-26T16:12:35 < Cracki> maybe look for startups that sell "home surgery kits" for those muricans who'd rather saw off their leg onthe kitchen table than pay the hospital bill
2020-02-26T16:12:46 < jadew> lol
2020-02-26T16:12:50 < jadew> is there such a thing?
2020-02-26T16:13:10 < Cracki> military surplus medkits are probably good for an amputation
2020-02-26T16:13:39 < Cracki> I think anyone who wants to make money off that situation is gonna go into health insurance instead. no need to saw on that leg while it's strong
2020-02-26T16:14:35 < Cracki> perhaps invest in security systems and all kinds of defense, also weapons.
2020-02-26T16:14:51 < jadew> right, weapons
2020-02-26T16:15:05 < Cracki> maybe get a dog or two that are trained, but I'd wait with that until your own country is starting to go mad
2020-02-26T16:15:10 < jadew> people kill each other all the time
2020-02-26T16:15:42 < Cracki> I'd also invest in anything that supports the following baby boom
2020-02-26T16:15:51 < Cracki> humans tend to fuck like rabbits after a culling
2020-02-26T16:16:15 < Cracki> prenatal and neonatal care
2020-02-26T16:16:42 < jadew> dippers
2020-02-26T16:16:55 < Cracki> also invest in anything that has trade value, such as vodka :>
2020-02-26T16:16:56 < jadew> and milk
2020-02-26T16:17:12 < Cracki> addiction is a sure way to make money

2020-02-26T16:19:21 < Mangy_Dog> i want to make a simple small stm32 firmware programmer....
2020-02-26T16:19:50 < Mangy_Dog> that uses the programmer protocol that stlink utility uses to upload firmware without dfu or bootloader
2020-02-26T16:20:20 < Mangy_Dog> i cant see any reason why its not possible to make a program for a stm32f103 and it reads off an sdcard with the bin file and uploads the bin to the target
2020-02-26T16:20:31 < Mangy_Dog> in the same quick easy process as the stlink utility
2020-02-26T16:20:58 < Cracki> swd is the "protocol"

2020-02-26T16:21:16 < Cracki> as I was saying, i'd just take a raspi for this
2020-02-26T16:21:22 < Cracki> no need to implement anything
2020-02-26T16:21:38 < Mangy_Dog> i like the idea of something simular and smaller than using a rasp
2020-02-26T16:21:39 < karlp> Mangy_Dog: stm32programmer (using the serial bootloader) has been ported to stm32 itself repeatedly I think,
2020-02-26T16:21:46 < karlp> I thik it's even in the repo itself iirc.
2020-02-26T16:22:01 < Mangy_Dog> karlp i want to do this bootloaderless
2020-02-26T16:22:07 < karlp> the rom bootloader.
2020-02-26T16:22:15 < karlp> you could also do it via swd/jtag, sure.
2020-02-26T16:22:31 < Mangy_Dog> nods swd wireup for sure
2020-02-26T16:22:31 < karlp> black magic probe has the complete gdb server running on an stm32, so you can definitely leave out most of it
2020-02-26T16:22:48 < Mangy_Dog> just not sure how the serial send commands work to get it to take the data
2020-02-26T16:22:49 < karlp> dongs here has a "ghetto flasher" which is same, but he's unlikely to share it.
2020-02-26T16:22:58 < karlp> well, that's up to you
2020-02-26T16:23:15 < karlp> arm adi-v5 plus the flash programming manual for your targets if you want to do it via swd/jtag,
2020-02-26T16:23:23 < karlp> an2606 if you want to do it via the rom bootlaoders
2020-02-26T16:23:28 < karlp> (which would be far easier IMO)
2020-02-26T16:23:41 < karlp> especially if the goal is just flashing
2020-02-26T16:23:49 < Mangy_Dog> nods
2020-02-26T16:24:36 < karlp> (like, wayyyyyyy easier)
2020-02-26T16:24:50 < Mangy_Dog> but that means my target needs a boot loader to begin with
2020-02-26T16:25:02 < Mangy_Dog> which it wont be
2020-02-26T16:25:19 < Cracki> wha'ts your target
2020-02-26T16:25:23 < Mangy_Dog> im dealign with raw virgin chips
2020-02-26T16:25:26 < Cracki> ir likely has a bootloader in rom (not flash)
2020-02-26T16:25:27 < Mangy_Dog> prolly f103
2020-02-26T16:25:32 < Cracki> has a rom bootloader
2020-02-26T16:25:53 < Cracki> you can't erase it, and you only need to touch boot0/boot1 to run it
2020-02-26T16:26:58 < karlp> Mangy_Dog: _alllll_ stm32s have a rom bootloader, you get at least serial, and optionally (see an2606 and your part datasheets) spi/i2c/can/usb-dfu
2020-02-26T16:27:27 < Mangy_Dog> hmm ok
2020-02-26T16:28:00 < Mangy_Dog> swd still seems simpler, as long as i know the commands to send over spi to the target to say HAY heres a flash package... take it!
2020-02-26T16:28:30 < qyx> thats not that simple
2020-02-26T16:28:46 < Cracki> swd isn't just spi tho
2020-02-26T16:29:02 < Cracki> uart to bootloader is way simpler
2020-02-26T16:30:23 < Mangy_Dog> so this boot loader youre talking of isnt the usual bootloader that makes the chip take a couple seconds to boot up? it doesnt block the instant boot up?
2020-02-26T16:30:32 < Cracki> correct
2020-02-26T16:30:53 < Mangy_Dog>  hmm ok
2020-02-26T16:30:55 < Cracki> boot0/1 choose what to boot from. flash is normal operation, rom bootloader is another
2020-02-26T16:31:49 < Cracki> it's already there. you never noticed ;)
2020-02-26T16:31:58 < Mangy_Dog> nodnods
2020-02-26T16:32:17 < Cracki> and it's only active when you start the target with the right voltage on boot0/1
2020-02-26T16:32:41 < Cracki> and you only activate it once for programming, then it's inactive again
2020-02-26T16:33:05 < Cracki> (until you choose to boot the rom bootloader again)
2020-02-26T16:37:13 < Mangy_Dog> nods

2020-02-26T16:39:26 < doomba> is CAN used in anything other than vehicles?
2020-02-26T16:40:33 < Mangy_Dog> i think some factory hardware uses can
2020-02-26T16:40:43 < Thorn> I've used it in my projects instead of rs-485
2020-02-26T16:40:46 < Thorn> there're avionics protocols on top of CAN iirc
2020-02-26T16:41:12 < doomba> i see an emerging black market for CAN stuff
2020-02-26T16:43:14 < doomba> once the insurance industry gets legislation passed making automobile telematics mandatory
2020-02-26T16:43:20 < bitmask> herro
2020-02-26T16:43:22 < karlp> Mangy_Dog: what is this "usual bootloader that takes a few seconds to start up" that you're talking about?
2020-02-26T16:43:25 < karlp> is that some arduino thing?
2020-02-26T16:43:37 < doomba> a whole industry of products to help people save money could emerge
2020-02-26T16:44:02 < bitmask> any chemists in here?
2020-02-26T16:44:20 < bitmask> https://i.imgur.com/6ZeReqx.jpg is this copper metal or copper (i) oxide
2020-02-26T16:44:41 < Cracki> does it conduct
2020-02-26T16:44:44 < Cracki> (when dry)
2020-02-26T16:45:01 < bitmask> nope, not sure if its cause a thin layer of oxide formed or not
2020-02-26T16:45:03 < Cracki> I would assume that copper oxide doesn't but eh
2020-02-26T16:45:17 < bitmask> copper i oxide is a semiconductor
2020-02-26T16:45:29 < Cracki> melt it?
2020-02-26T16:45:42 < Cracki> wait, at what temp does copper even melt
2020-02-26T16:45:49 < bitmask> i think its pretty high
2020-02-26T16:46:03 < doomba> you could try a grind test or a torch test
2020-02-26T16:46:19 < bitmask> meaning?
2020-02-26T16:46:26 < Mangy_Dog> kalp, maybe?
2020-02-26T16:46:28 < Cracki> picture looks almost like your stuff https://msapchemistry1213.weebly.com/copper-lab.html
2020-02-26T16:46:34 < Mangy_Dog> well things like rogerclarks project
2020-02-26T16:46:39 < Cracki> torch test gives you a colored flame
2020-02-26T16:46:43 < doomba> well. usually you do some destructive test like grind it or set it on fire and see what color the flame or sparks are
2020-02-26T16:46:46 < Mangy_Dog> to make flashing through usb easy
2020-02-26T16:46:50 < Cracki> color determines what it is
2020-02-26T16:46:54 < doomba> or you can put it into some kind of acid solution and see what color it changes
2020-02-26T16:47:25 < Cracki> nvm, that page shows zinc
2020-02-26T16:47:40 < doomba> you can also do a hardness test
2020-02-26T16:47:50 < doomba> if you have a tool for that
2020-02-26T16:48:10 < Cracki> bite on it or what
2020-02-26T16:48:14 < doomba> but this crumble... would probably be hard
2020-02-26T16:48:15 < bitmask> heh
2020-02-26T16:48:16 < BrainDamage> if you have a scale you can just measure density
2020-02-26T16:48:30 < BrainDamage> copper oxide is 6g/cm^3, copper 8
2020-02-26T16:48:36 < BrainDamage> sorry, 9
2020-02-26T16:48:46 < BrainDamage> so it should be easy to distinguish
2020-02-26T16:48:48 < Cracki> you'd have to measure its volume for that
2020-02-26T16:48:54 < bitmask> which copper oxide
2020-02-26T16:48:56 < Cracki> so compress or measure displacement of water or sth
2020-02-26T16:48:56 < bitmask> i or ii
2020-02-26T16:48:59 < oz4ga> copper oxide is diamagnetic
2020-02-26T16:48:59 < BrainDamage> i
2020-02-26T16:49:13 < Cracki> is copper non-oxide diamagnetic too
2020-02-26T16:49:14 < BrainDamage> diamagnetism is quite hard to measure
2020-02-26T16:49:21 < BrainDamage> you need huge field strengths
2020-02-26T16:50:05 < doomba> https://www.worldoftest.com/portable-hardness-testers-handheld-hardness-testers
2020-02-26T16:50:16 < doomba> "sclerometers"
2020-02-26T16:50:58 < BrainDamage> he should be able to measure density with materials he has already
2020-02-26T16:51:08 < BrainDamage> water for the volume as cracki said, and a scale for the weight
2020-02-26T16:51:32 < BrainDamage> since one is 50% more than the other, he even has quite some leeway in the measurement tolerance
2020-02-26T16:51:56 < bitmask> alright, if heating it doesnt do what I want then i'll try that
2020-02-26T16:51:59 < BrainDamage> flame test would not work well, since you'd risk the copper oxidizing on the fly in the flame
2020-02-26T16:52:12 < Cracki> got a bunsen burner or sth?
2020-02-26T16:52:23 < bitmask> heating to try and form copper ii oxide, not flame test
2020-02-26T16:52:28 < Cracki> ic
2020-02-26T16:52:39 < bitmask> i have a butane torch
2020-02-26T16:52:59 < Cracki> how much in weight do you have there anyway
2020-02-26T16:53:21 < bitmask> not sure, i'll weigh it
2020-02-26T16:54:26 < Cracki> looks like a few grams, so volume displacement would need to be accurate to fractions of a milliliter
2020-02-26T16:54:56 < BrainDamage> pile in a narrow tube
2020-02-26T16:55:06 < BrainDamage> like a pencil pipe
2020-02-26T16:55:07 < bitmask> glassware is something i'm lacking in
2020-02-26T16:55:11 < Cracki> yes, I was thinking syringe but there's surely glass ware for this too
2020-02-26T16:55:25 < BrainDamage> get an old bic pen
2020-02-26T16:55:25 < Cracki> insulin syringes are quite narrow
2020-02-26T16:55:27 < bitmask> I do have some syringes
2020-02-26T16:55:40 < BrainDamage> or that
2020-02-26T16:55:51 < Cracki> if you can measure a full milliliter accurately, you can use that to "scale" the bic pen
2020-02-26T16:56:17 < bitmask> 13.92 grams
2020-02-26T16:57:10 < Cracki> so that's 2.32 ml (6 g/cm3) or 1.55 ml (9g/cm3) displacement
2020-02-26T16:57:49 < Cracki> if it's flaky, maybe break it up some more, so no air gets trapped along with it
2020-02-26T16:58:24 < bitmask> that might be tough, if its metal then i'd bet theres at least some oxide in it
2020-02-26T16:59:10 < BrainDamage> 1ml/(0.5cm/2)^2pi = 5cm
2020-02-26T16:59:27 < BrainDamage> so in a pipe of 0.5cm diameter, you have 5cm difference in the column
2020-02-26T16:59:31 < BrainDamage> that's quite easy to notice
2020-02-26T17:00:07 < bitmask> k
2020-02-26T17:00:18 < BrainDamage> if it's instead 1cm diameter, it's 1cm difference in height
2020-02-26T17:00:27 < BrainDamage> so no need for specialized tools
2020-02-26T17:05:18 < bitmask> im gonna order some test tubes anyway, they will come in handy
2020-02-26T17:05:34 < bitmask> should probably get some beakers too
2020-02-26T17:05:44 < Cracki> 2 cm diameter test tube would be 0.3 cm height for 1 ml

2020-02-26T20:36:03 < antto> not sure, but i was able to walk around the early code
2020-02-26T20:36:17 < Cracki> it's counting down from something and that maybe shouldn't be 0
2020-02-26T20:36:43 < Cracki> so either something is told to be 0 when itshouldn't, or it was never given a value and 0 is a default

2020-02-26T20:43:09 < antto> it cought a breakpoint which i put in the Reset_Vector thing, and i could walk from there untill it froze in one of the functions that sets up the clocks/PLL
2020-02-26T20:43:36 < antto> so it seems as if debugging wurkz

2020-02-26T21:42:13 < PaulFertser> zyp: I do not consider pozidriv special (btw, how would an educated UK person properly pronounce that trademark), I've just cited an (apparently not so amusing) facebook rant about IKEA not "warning" about using pozidriv screws (but who needs that warning, the blind people)?
2020-02-26T21:43:11 < PaulFertser> zyp: I thought home automation is either zigbee-based or 802.15.4 6lowpan, so I can't see how "tradfri" fits into this picture. Hence the confusion (and I am still confused).
2020-02-26T21:44:10 < Steffanx> zigbee4ever.
2020-02-26T21:45:51 < Steffanx> you do know tradfri = zigbee right, PaulFertser?
2020-02-26T21:46:08 < PaulFertser> Steffanx: no, how would I?
2020-02-26T21:47:39 < Steffanx> Duckduckgo?
2020-02-26T21:47:40 < PaulFertser> Steffanx: I watched a 15-minutes video yesterday of some guy with an awful accent "hacking" the tradfri remote controller. And by "hacking" he meant adding esp8266 gpio in parallel with the buttons...
2020-02-26T21:48:01 < zyp> PaulFertser, trådfri is ikea's range of zigbee lights
2020-02-26T21:48:26 < Steffanx> its not just lights.
2020-02-26T21:48:37 < zyp> it's standard ZLL/ZHA, so it works with other stuff
2020-02-26T21:48:48 < Steffanx> even blinds and "switches" (as in a relay module inside some socket thingy)
2020-02-26T21:49:40 < PaulFertser> OK, so https://www.home-assistant.io/blog/2017/04/17/ikea-tradfri-internet-of-things-done-right/ I see

2020-02-26T21:51:38 < zyp> some are still operated by plain old light switches though

2020-02-26T21:54:37 < Steffanx>  idk.
2020-02-26T21:54:40 < zyp> the sunricher stuff? that's also connected to the deconz mesh
2020-02-26T21:55:14 < Steffanx> oh, i missed the word "some" in your sentence. that confused me :P
2020-02-26T21:55:26 < BrainDamage> huh, that's surprisingly well done
2020-02-26T21:55:30 < BrainDamage> so rare for iot
2020-02-26T21:58:16 < Steffanx> I just setup everything of my zigbee network through my home assistent setup using the deconz stick. Only weak point is that shit doesnt work when it's the HA server (local) is down.
2020-02-26T22:00:41 < PaulFertser> catphish: hey! How to properly say "pozidriv"
2020-02-26T22:00:59 < Steffanx> is it even english?

2020-02-26T22:01:52 < zyp> I imagine it's a contracted form of «positive drive», whatever that's supposed to mean

2020-02-26T22:09:59 < englishman> then after 366 days it breaks
2020-02-26T22:11:08 < aandrew> yeah I thought philips camming out was a design feature that was misunderstood, and then when you ahve shit metal to make the screws it ends up destroying them which was not part of the design
2020-02-26T22:17:22 < Steffanx> zyp: So from what i understand is that your zigbee stuff keeps working even when your remove your deconz stick from the equation?
2020-02-26T22:17:34 < Steffanx> *you remove
2020-02-26T22:18:18 < zyp> yes
2020-02-26T22:19:20 < zyp> the ikea gateway does the same
2020-02-26T22:19:44 < zyp> I mean, if you have an ikea gateway and unplug it, the switches will still work

2020-02-27T00:00:15 < karlp> qyx: yeah, but too much for the f4 black pill boards..
2020-02-27T00:04:41 < Cracki> what are x chapters and why would anyone pirate those
2020-02-27T00:06:51 < Thorn> they should have been a part of the main book
2020-02-27T00:07:07 < Thorn> but they released them separately 5 years later

2020-02-27T00:23:49 < qyx> fellow kicaders, if I delete part of the schematic and then a corresponding part of the pcb
2020-02-27T00:24:05 < qyx> how do I check if there is anything more on te pcb
2020-02-27T00:24:23 < qyx> I mean, if I forgot to delete something from the pcb
2020-02-27T00:24:42 < qyx> when a symbol is added on the sch, F8 updates the pcb
2020-02-27T00:24:57 < qyx> but it doesn't delete footprints without symbols in the sch
2020-02-27T00:25:18 < zyp> dunno about kicad, but in altium when you hit «Update PCB document» it does a diff between schematic and layout and lists changes
2020-02-27T00:27:35 < zyp> (and in altium it can absolutely remove stuff too, not just add)
2020-02-27T00:29:10 < karlp> qyx: isn't it just these tickboxes? https://imgur.com/a/UNMirbk
2020-02-27T00:30:55 < qyx> wut https://i.imgur.com/QmNTula.png
2020-02-27T00:31:25 < karlp> get a better kicad? :)
2020-02-27T00:31:31 < zyp> you probably need the premium version to get that
2020-02-27T00:31:55 < karlp> this is 5.99-r17670, but it'ðs been like that in all the ones I've been using for a while
2020-02-27T00:31:55 < qyx> :(
2020-02-27T00:31:58 < qyx> this is 5.0.2
2020-02-27T00:32:03 < karlp> I decided a while ago that the nighlies were the only kicad worth running.
2020-02-27T00:32:12 < karlp> 5.0.2 appears to be "stable, like debian"
2020-02-27T00:32:30 < qyx> I decided that apt install kicad is the way to go
2020-02-27T00:32:42 < qyx> apparetnly wrong
2020-02-27T00:33:07 < karlp> you don't even have kicad 5.1.x?

2020-02-27T00:33:18  * karlp shrugs
2020-02-27T00:33:22 < qyx> did you compile the thing?
2020-02-27T00:33:29 < qyx> I refuse to do that again
2020-02-27T00:34:05 < karlp> hell no.
2020-02-27T00:34:18 < qyx> thanks thor
2020-02-27T00:34:39 < karlp> there's a copr for fedora for nightly, and ppas for both nightly and currenty stable, and you can even install them both
2020-02-27T00:34:47 < karlp> ppas for ubuntu style people
2020-02-27T00:35:28 < karlp> debian itself looks classicaly debian complicated
2020-02-27T00:35:34 < qyx> I'll check when theres no work to do
2020-02-27T01:12:28 < antto> qyx get 5.1.x from ze debian backpr0tz
2020-02-27T01:13:01 < antto> you don't have to delete stuff from the PCB, you delete stuff in the schematic and u press ze F8
2020-02-27T01:13:39 < qyx> except that it doesn't work
2020-02-27T01:13:44 < qyx> at least not in 5.0.2
2020-02-27T01:13:49 < antto> are the footprints locked?
2020-02-27T01:14:01 < qyx> they simply stay
2020-02-27T01:14:01 < qyx> no
2020-02-27T01:14:09 < antto> if F8 doesn't do it, there should be the older way "import netlist" which gives moar optionz
2020-02-27T01:14:28 < antto> but you gotta eggsport it from eeschema first, of course
2020-02-27T01:14:35 < qyx> fukit
2020-02-27T01:14:40 < antto> like in kicad 4.x dayz
2020-02-27T01:15:00 < qyx> yeah, that was exactly the point where I gave up when trying kicad 4.x
2020-02-27T01:15:08 < antto> aww
2020-02-27T01:15:21 < qyx> because the whole process was simply dumb for normal fork

2020-02-27T02:00:27 < oz4ga> Thank you for starting to talk KiCAD. I just did some checkups on my first KiCAD project. I decided to change a component half way through the whole process. I've prograstinated checking how muc the change will influence th ePCB. Looks like I can wing it with minimal changes

2020-02-27T07:53:16 < jadew> first case in Romania
2020-02-27T07:53:39 < jadew> seeded by a guy from Italy
2020-02-27T07:54:02 < jadew> given that so many countries were seeded by italians, I'm gonna go on a limb and assume that all of Italy is fucked
2020-02-27T07:54:45 < jadew> BrainDamage, what's the situation there? anything on the news?
2020-02-27T07:56:00 < jadew> the worldometer news report is wrong
2020-02-27T07:56:35 < jadew> it didn't happen 3 weeks ago, it happened 1 week ago, and the infected person is not from Italy, he was one of the people who got in contact with the infected person
2020-02-27T07:56:51 < jadew> the infected person was in Romania for 3-4 days
2020-02-27T07:57:10 < jadew> everyone else he came in contact with is in quarantine
2020-02-27T08:01:06 < antto> corizzle vizzle is coming to a town near u
2020-02-27T08:01:18 < jadew> it's already in my town
2020-02-27T08:01:26 < jadew> they brought the infected guy here
2020-02-27T08:03:16 < jadew> I see Iran is ramping up the testing
2020-02-27T08:03:31 < jadew> we'll probably see that number go into the 10s of thousands soon
2020-02-27T08:15:12 < benishor> jadew: what city are you from?
2020-02-27T08:16:15 < benishor> or currently in, better siad

2020-02-27T08:35:27 < jadew> benishor, Bucharest
2020-02-27T08:35:54 < jadew> Brasov is a touristic hub, it could already be there
2020-02-27T08:36:36 < jadew> last week I was at an international sports event... very bad decision to go there
2020-02-27T08:36:46 < jadew> but I was dragged
2020-02-27T08:38:04 < jadew> the guy that has it was from Craiova and they brought him here
2020-02-27T08:38:16 < jadew> 25 yo, no symptoms
2020-02-27T08:38:36 < jadew> he's probably going to recover
2020-02-27T08:39:07 < jadew> I just learned that almost all flues come from Asia
2020-02-27T08:39:49 < jadew> we should just ban them
2020-02-27T08:40:43 < jadew> looks like the number of cases is picking up again
2020-02-27T08:41:52 < jadew> Estonia just got their first case too
2020-02-27T08:48:56 < antto> on teh TV here they say that babiez and younger folks can get thru it, but older peoplez are moar vulnerable
2020-02-27T08:49:35 < antto> wut can u do to help yerself? get moar vitamin C or sumfin?
2020-02-27T08:49:36 < jadew> let's hope that's true
2020-02-27T08:49:54 < jadew> yeah, I think vitamin C would help
2020-02-27T08:51:36 < antto> on teh news they also said that since teh vizzle is now in .ro, it is *most* probably also in .bg and we should eggspect first confirmations to happen soon
2020-02-27T08:52:23 < antto> i wouldn't mind taking a break from $job
2020-02-27T08:52:41 < jpa-> did we get a lolcat in the channel?
2020-02-27T08:52:50 < antto> >:)
2020-02-27T08:53:22 < jadew> antto, was just on the phone with my wife discussing this
2020-02-27T08:54:09 < jadew> she's looking for ways to not go to work if another confirmed case appears and it doesn't have a clear link to the Italian case
2020-02-27T08:54:13 < antto> why didn't teh EU kinda lock the internal borders a bit when teh vizzle got here in the beginning
2020-02-27T08:54:24 < jadew> antto, they're stupid
2020-02-27T08:54:45 < antto> i'd guess because $$$
2020-02-27T08:54:52 < jadew> yeah
2020-02-27T08:55:16 < jadew> if Italy closed its borders once the outbreak started, the EU could have been fine
2020-02-27T08:55:24 < jadew> but since they didn't (and they're still open)
2020-02-27T08:55:40 < jadew> they managed to infect the rest of Europe too
2020-02-27T08:56:04 < jadew> lots of Romanians fled Italy once that outbreak happened
2020-02-27T08:56:09 < jadew> they should have been kept there
2020-02-27T08:56:27 < jadew> because there's no way for us to verify that the people entering our countries came from Italy or somewhere else
2020-02-27T08:56:37 < jadew> so they could just lie and avoid the quarantine
2020-02-27T08:56:42 < antto> yesterday on teh news here they showed a bunch of gypsies on teh bus station waiting for a bus to "france" supposedly, which passes thru italy, and they were acting half-serious and looked like drunks
2020-02-27T08:56:49 < jpa-> lock the border as in prevent *all* traffic there? lol, the already fragile italian economy would have collapsed in a week
2020-02-27T08:57:18 < jadew> jpa-, yeah, that's probably why they didn't do it
2020-02-27T08:57:31 < jadew> but if they have to put everything under lock down, it's going to happen anyway
2020-02-27T08:58:21 < Steffanx> Ohno is it corona again?
2020-02-27T08:58:26 < antto> no

2020-02-27T08:59:26 < jadew> well... if china is any indication of what could happen, we have very grim times ahead
2020-02-27T08:59:48 < antto> do chinese eat a lot of vitamin C? ;P~
2020-02-27T09:00:05 < jadew> I don't think they eat a lot of anything these days
2020-02-27T09:00:14 < jadew> they've been under lockdown for a month
2020-02-27T09:00:31 < antto> yeah, but it seems to work
2020-02-27T09:01:01 < Steffanx> Did you pre-ordered yourself a "I survived Wuhan Virus" T-shirt yet jadew?
2020-02-27T09:01:32 < jadew> Steffanx, I'll get one at the end, depending how much of an achievement that is
2020-02-27T09:02:35 < antto> where are those t-shirts made?
2020-02-27T09:02:36 < Steffanx> Lock up wife and kid in the basement (if not already) and dont go outside..
2020-02-27T09:03:13 < jadew> Steffanx, that's the plan, but it enters into effect when the first person is detected, that has no obvious link to someone else
2020-02-27T09:03:24 < jadew> that's the signal that it is out of control
2020-02-27T09:03:32 < jpa-> jadew: how long will you stay under lockdown? a yer?
2020-02-27T09:03:34 < jpa-> *year
2020-02-27T09:03:56 < jadew> jpa-, however long necessary
2020-02-27T09:04:20 < jpa-> but "necessary" is totally subjective, what's your signal to come out?
2020-02-27T09:04:45 < antto> "TBD"
2020-02-27T09:04:51 < jadew> yeah, pretty much
2020-02-27T09:05:19 < jadew> if it is eradicated, or a safe vaccine is created, or it becomes a seasonal thing
2020-02-27T09:05:39 < antto> mm, a sizzle corizzle vizzle
2020-02-27T09:05:48 < jpa-> ok, so at least a year before any of those happens
2020-02-27T09:06:04 < Steffanx> I dont even think jadew is joking. Damn
2020-02-27T09:06:14 < antto> of course he ain't
2020-02-27T09:06:30 < jpa-> i briefly considered whether there is any point trying to prepare to stay indoors for a duration of epidemic, and then figured out that no, too long time compared to the actual risk for healthy young people
2020-02-27T09:06:31 < antto> teh sh*t is real
2020-02-27T09:06:51 < jadew> jpa-, we don't really know the risk yet
2020-02-27T09:07:01 < jadew> if it proves to be low, sure, we'll go out and catch it
2020-02-27T09:07:02 < jpa-> jadew: well, it's not ebola level :P
2020-02-27T09:07:07 < Steffanx> How comes antto didnt turn into haxoried or the haoh guy yet?
2020-02-27T09:07:08 < jadew> yeah, for sure
2020-02-27T09:07:23 < jpa-> and that's the trigger when i'll shut the door ;)
2020-02-27T09:07:23 < Steffanx> Haxorized*
2020-02-27T09:07:23 < jadew> but if it's like... 5-10%, then I'd rather stay indoors
2020-02-27T09:07:27 < antto> Steffanx i'm late for wurk

2020-02-27T09:07:59 < antto> it's been like that for months
2020-02-27T09:08:11 < jadew> the current CFR could be due to good health care, once it's an epidemic, that number will surely go up
2020-02-27T09:08:16 < jadew> but we don't know by how much
2020-02-27T09:08:34 < jadew> once I know that, I'll be able to take a decision on weather I'll keep staying on lockdown or not
2020-02-27T09:08:42 < Steffanx> Keep?
2020-02-27T09:09:02 < jadew> Steffanx, assuming that information arrives after the first unlinked case

2020-02-27T09:09:28 < antto> u only need IRC
2020-02-27T09:09:35 < jadew> Steffanx, well, I'm listening to them
2020-02-27T09:09:50 < Steffanx> Only old guys do HAM. And they all die
2020-02-27T09:10:00 < jadew> haha
2020-02-27T09:10:05 < antto> old guys are vuleraburu
2020-02-27T09:10:07 < jadew> their kids might know how to operate that gear
2020-02-27T09:10:29 < antto> kids b too busy rubbing their phonez
2020-02-27T09:12:09 < dongs> oh my fuck
2020-02-27T09:12:21 < dongs> arduinoi ide is utterly disgusting lmao
2020-02-27T09:12:30 < dongs> im trying to build some retards proj for nrf52
2020-02-27T09:12:36 < dongs> it recompiles for like 30+seconds
2020-02-27T09:12:38 < dongs> on each change
2020-02-27T09:12:51 < dongs> it basically revuilds everythign from scratch
2020-02-27T09:13:11 < jadew> broken makefiles maybe?
2020-02-27T09:13:23 < dongs> makefiles?????
2020-02-27T09:13:29 < dongs> i said retarduino
2020-02-27T09:13:32 < jadew> I don't know how it's working...
2020-02-27T09:13:37 < dongs> yea nobody does
2020-02-27T09:13:38 < jadew> I assume it's generating makefiles, no?
2020-02-27T09:13:41 < dongs> no
2020-02-27T09:13:51 < dongs> it does cat *.ino > nigger.cpp and builds it
2020-02-27T09:13:56 < antto> crapduino IDE is crap? breaking newz!
2020-02-27T09:13:58 < dongs> but before that it builds all the nrf shite over and over
2020-02-27T09:14:01 < jadew> oh...
2020-02-27T09:14:18 < jadew> well, yeah, what did you expect
2020-02-27T09:15:46 < dongs> not complete insanity at least
2020-02-27T09:16:09 < Steffanx> Anyway. Back to the real world problems: my car windows are frozen.
2020-02-27T09:16:21 < dongs> hit the reset button
2020-02-27T09:16:25 < antto> it's over 14 degrees here
2020-02-27T09:16:28 < jadew> Steffanx, start the car and let it heat up
2020-02-27T09:16:35 < Steffanx> I hate deicing my car windows
2020-02-27T09:16:44 < Steffanx> That wont work
2020-02-27T09:17:12 < antto> move to $hotter_country
2020-02-27T09:17:13 < Steffanx> My car doesnt heat up much when running stationary. Not enough at least
2020-02-27T09:19:37 < jpa-> Steffanx: plug up the heater cord to the outlet next to your parking space
2020-02-27T09:20:53 < antto> u need high temperature to defrost ice
2020-02-27T09:21:02 < antto> put a bomb on ze window
2020-02-27T09:22:20 < antto> my solutions are sometimes eggsplosive ;P~

2020-02-27T09:26:14 < antto> where is ur positivism?
2020-02-27T09:26:28 < oz4ga> yes I'm over 50. no chance at all. only a matter time. take good care of ##corona32
2020-02-27T09:27:11 < antto> i'm not uber young either, according to muh white hairz
2020-02-27T09:27:24 < jadew> jpa-, see, oz4ga is a HAM operator
2020-02-27T09:27:31 < antto> hahaha
2020-02-27T09:27:32 < jadew> I can talk to him when IRC goes down
2020-02-27T09:27:47 < antto> IRC will not go down, u fool
2020-02-27T09:28:05 < jadew> oh, Steffanx said I'd have nobody to talk to
2020-02-27T09:28:07 < antto> if it does, we're f*cked
2020-02-27T09:28:41 < antto> sh*t, i better go
2020-02-27T09:28:48 < antto> meh
2020-02-27T09:28:51 < jadew> well, radio is the last thing to go down
2020-02-27T09:29:12 < jadew> so it's not a bad idea to have some sort of radio transciever
2020-02-27T09:29:19 < jadew> at least one of those baofeng stations
2020-02-27T09:29:36 < jadew> they're particularly useful because they can work outside of the ISM/HAM bands
2020-02-27T09:30:02 < jadew> so if shit hits the fan, you can transmit on the ambulance service frequency or on the police freq.
2020-02-27T09:34:49 < oz4ga> except they are using encryption, so that won't work
2020-02-27T09:34:58 < jadew> they don't
2020-02-27T09:35:05 < oz4ga> they do here
2020-02-27T09:35:06 < jadew> not all of them anyway
2020-02-27T09:35:24 < jadew> here a large part of it is open
2020-02-27T09:39:13 < jadew> oz4ga, anything interesting about the ncov on the HAM bands?
2020-02-27T09:41:22 < oz4ga> I don't know. Didn't care to switch the radios on. The case we got so far is a journalist who has been skiing in north italy. He didn't manage to infect hes family, so no panik ... yet
2020-02-27T09:41:54 < oz4ga> I mainly do HF / Short Wave

2020-02-27T10:24:37 < jpa-> Steffanx: neither do cars here, but pretty much every parking space has an outlet for heating the car :)
2020-02-27T10:24:57 < Steffanx> Heh. Nothing like that here
2020-02-27T10:26:34 < jpa-> how do you people survive -25°C winters?

2020-02-27T11:33:18 < benishor> :|
2020-02-27T11:33:35 < Thorn> they've had a pretty large assortment of TI products (probably larger than any other western mfr) with stocks
2020-02-27T11:33:47 < benishor> apparently they don't let you purchase

2020-02-27T11:34:29 < benishor> too bad. I liked farnell as my one stop shop

2020-02-27T11:38:37 < jadew> benishor, looks to me like you can still purchase those schmitt triggers
2020-02-27T11:38:43 < jadew> it's just that they cost 10 million pounds
2020-02-27T11:39:38 < benishor> that's what I meant
2020-02-27T11:39:47 < benishor> who the hell pays that ridiculous amount
2020-02-27T11:39:55 < benishor> it was probably a technical limitation
2020-02-27T11:40:06 < benishor> so they hacked it :D
2020-02-27T11:40:11 < jadew> anyone will be able to, once the UK finally leaves the EU
2020-02-27T11:40:17 < jadew> they just adjusted for inflation

2020-02-27T14:35:36 < jadew> we're fucked
2020-02-27T14:36:26 < Thorn> btw can we expect utility outages such as water and electricity? 
2020-02-27T14:36:39 < jadew> Thorn, I was wondering the same thing
2020-02-27T14:36:46 < jadew> I assume they'd keep those working
2020-02-27T14:36:57 < jadew> otherwise people will die in the streets or try to leave the cities
2020-02-27T14:37:11 < jadew> it would make any outbreak much much worse
2020-02-27T14:37:22 < BrainDamage> jadew: to answer you, the rate of infection here is lowering
2020-02-27T14:37:48 < BrainDamage> we still get new cases, but no more exponential growth
2020-02-27T14:38:14 < jadew> BrainDamage, that's good to hear, I really hope you manage to keep it under control
2020-02-27T14:38:30 < BrainDamage> also, you're really halfway into panic/anxiety, you should consider finding an outlet for those
2020-02-27T14:39:28 < BrainDamage> even if a single region in china gets a couple thousand new infections, it's not as bad overall on the 50 thousand in the whole place
2020-02-27T14:40:10 < jadew> BrainDamage, yeah, but it's definite proof that they've been hiding the real numbers
2020-02-27T14:40:25 < BrainDamage> also, it's kind of inevitable that the virus spread, the main effort/concern is to keep the infection rate to not overload the sanitary system
2020-02-27T14:40:35 < jadew> yep
2020-02-27T14:40:46 < jadew> here it would be overloaded really fast
2020-02-27T14:41:42 < jadew> I heard they have 2500 beds available and only 2 rooms that are fully equipped for anything
2020-02-27T14:42:05 < jadew> I assume those will be reserved for high ranking officials
2020-02-27T14:43:18 < jadew> BrainDamage, you're right, I'm operating a bit in panic mode, because I don't know what to expect and I want to be prepared
2020-02-27T14:43:24 < jadew> and not make any mistakes early on
2020-02-27T14:52:09 < karlp> "a bit" :)

2020-02-27T14:56:15 < karlp> there's absolutely nothing I can do about it.
2020-02-27T14:56:22 < Cracki> jadew, the "52x" is from ONE DAY where they reported 4 instead of xxx number.
2020-02-27T14:56:36 < jadew> Cracki, hah, good to know
2020-02-27T14:56:37 < Cracki> you're former soviet area, aren't you
2020-02-27T14:56:42 < Cracki> read carefully
2020-02-27T14:56:56 < Cracki> news is always sensationalist
2020-02-27T14:57:07 < Cracki> it always has a slant
2020-02-27T14:57:09 < jadew> still... that's still proof of fake numbers

2020-02-27T14:57:18 < jadew> karlp, there is tho
2020-02-27T14:57:32 < jadew> if you stay protected, you don't help spread the disease
2020-02-27T14:57:42 < kakigate> does 1000BASE-LX implement full duplex over single fiber
2020-02-27T14:57:52 < karlp> yes, but that's all there is to it.
2020-02-27T14:58:13 < BrainDamage> fear is not necessary for protection, I'd argue the opposite
2020-02-27T14:58:25 < Cracki> kakigate, pair of fibers in the worst case. what are you fibering?
2020-02-27T14:58:30 < kakigate> or are my single fiber devices actually running duplex copper in and communicating in half-duplex in fiber?
2020-02-27T14:58:49 < Cracki> you can send light both ways over one fiber, I think
2020-02-27T14:58:56 < kakigate> sure
2020-02-27T14:58:57 < Thorn> buy 2-3 months worth of bottled water, canned food. face masks, disinfectant. make sure utility / phone / internet bills can be paid online or pay them in advance if possible. what else?
2020-02-27T14:59:07 < kakigate> but is it running in duplex mode
2020-02-27T14:59:08 < Cracki> I'm sure nothing there is doing half-duplex
2020-02-27T14:59:18 < kakigate> 1000 in both directions?
2020-02-27T14:59:21 < kakigate> same time
2020-02-27T14:59:30 < jadew> Thorn, batteries
2020-02-27T14:59:41 < Cracki> all the 1000base-lx transceivers I see have two fiber ports, one for each direction
2020-02-27T14:59:45 < jadew> flashlights
2020-02-27T14:59:55 < BrainDamage> fleshlights
2020-02-27T14:59:55 < Cracki> do you have anything optical that runs on one fiber?
2020-02-27T15:00:01 < karlp> I do :)
2020-02-27T15:00:01 < kakigate> I have one 1000base-sx/lx that has one
2020-02-27T15:00:05 < jadew> that too, if you're single :)
2020-02-27T15:00:11 < karlp> they use a different frequency for tx/rx.
2020-02-27T15:00:28 < kakigate> you mean wavelenght
2020-02-27T15:00:34 < karlp> same thing....
2020-02-27T15:00:37 < BrainDamage> ... it's the same thing
2020-02-27T15:00:38 < kakigate> it is
2020-02-27T15:00:53 < BrainDamage> WDM: because we're too cool to call it FDM
2020-02-27T15:01:03 < karlp> but they're often labelled in nm, so I guess wavelength would be the normal way of talking about it, sure.
2020-02-27T15:01:17 < kakigate> are you certain?
2020-02-27T15:01:24 < karlp> certain about what?
2020-02-27T15:01:31 < karlp> the sfp literealy says tx: blahnm, rx: blah nm on it.
2020-02-27T15:01:46 < kakigate> that I have full-duplex in single fiber
2020-02-27T15:01:52 < karlp> it has a single fibre port, it's like a normal dual one, just missing a port.
2020-02-27T15:01:56 < karlp> yes...
2020-02-27T15:02:03 < Cracki> it's like radio
2020-02-27T15:02:05 < karlp> ~all fibre to the home is like that here.
2020-02-27T15:02:18 < BrainDamage> find the safety info and it'll report the laser freqs
2020-02-27T15:02:29 < kakigate> why would you buy one with dual port
2020-02-27T15:02:45 < kakigate> chinese make it both ways
2020-02-27T15:02:52 < kakigate> cost about the same
2020-02-27T15:02:56 < BrainDamage> dual port gives you flexibility on the fiber type
2020-02-27T15:03:19 < kakigate> I have single mode cable
2020-02-27T15:03:21 < BrainDamage> fiber coms can run for long sections, where attenuation matters
2020-02-27T15:03:57 < karlp> eg https://www.fs.com/products/11795.html
2020-02-27T15:04:15 < karlp> you buy the sort that matches what fibre you have...
2020-02-27T15:04:38 < karlp> single mode cable, with two fibres? or one?
2020-02-27T15:05:28 < karlp> the "km" rating on those bidir sfps is otuput power basically, so in theory you don't burn out the far sides receiver...
2020-02-27T15:15:06 < zyp> -LX uses two fibers, single fiber duplex is -BX
2020-02-27T15:17:15 < effractur> but don't forget that for bidi you need a different one at the other end
2020-02-27T15:17:24 < effractur> to swap the tx/rx wavelengths
2020-02-27T15:17:32 < zyp> my internet connection is 1000base-bx, so I got a cheap media converter and a suitable SFP and replaced the huge box the ISP provided
2020-02-27T15:17:35 < zyp> https://bin.jvnv.net/file/OV2am.jpg
2020-02-27T15:17:36 < zyp> yes
2020-02-27T15:18:10 < zyp> and to make it even more fun, there's three common wavelengths, so you've got at least four options of transceivers
2020-02-27T15:19:13 < zyp> 1310/1490 and 1310/1550
2020-02-27T15:19:28 < zyp> oh, there's 1490/1550 also
2020-02-27T15:19:34 < zyp> so six options
2020-02-27T15:23:16 < karlp> 1510/1590 too: https://www.fs.com/de-en/products/39776.html
2020-02-27T15:28:40 < zyp> fun
2020-02-27T15:29:03 < karlp> what's kaks even got? is this all academic?
2020-02-27T15:30:19 < effractur> i mean you can create a lot more options if you want
2020-02-27T15:30:31 < zyp> I'm not sure what the context here is
2020-02-27T15:30:55 < zyp> if it's a single fiber home internet connection it's probably GPON
2020-02-27T15:31:07 < effractur> zyp: no
2020-02-27T15:31:33 < effractur> almost all single fiber connections are probaly BiDi, if it is APC then it is gpon
2020-02-27T15:31:43 < effractur> or coax over fiber
2020-02-27T15:33:16 < karlp> APC?
2020-02-27T15:34:23 < effractur> http://www.fiber-optic-components.com/evolution-of-flat-pc-upc-and-apc-fiber-connectors.html
2020-02-27T15:34:29 < effractur> how the connector is cut
2020-02-27T15:34:55 < zyp> yes, GPON is normally APC
2020-02-27T15:35:15 < effractur> at least in NL they deployed 1 APC and 1 UPC fiber to each home
2020-02-27T15:36:32 < zyp> here ISPs deploy their own fibers
2020-02-27T15:37:22 < zyp> I've currently got BiDi, but as far as I know, the ISP I've got is the only major ISP here doing that, everybody else are doing GPON
2020-02-27T15:37:31 < effractur> gpon is cheaper
2020-02-27T15:37:49 < effractur> less active equipment needed
2020-02-27T15:37:53 < zyp> yes
2020-02-27T15:38:34 < effractur> here it is moslty BiDi only in the less dense areas GPON but all installed with the option to go back to BiDi
2020-02-27T15:38:44 < zyp> https://bin.jvnv.net/file/S8iYQ.jpg <- last place I lived I had two GPON connections coming in
2020-02-27T15:43:11 < zyp> speaking of, one of the GPON ISPs came knocking the other day, wanna offer me more speed for less money than what I'm currently paying
2020-02-27T15:43:39 < zyp> main reason I didn't say yes is I don't want a GPON box
2020-02-27T15:44:17 < zyp> told them I wanted to think about it, then asked current ISP for a counteroffer

2020-02-27T16:51:30 < jpa-> kakimir: so uh.. is that block supposed to output 1 whenever at least one of the bits matches?
2020-02-27T16:51:46 < kakimir> no
2020-02-27T16:51:55 < jpa-> well that is what it seems to do
2020-02-27T16:52:20 < jpa-> 74LVC86 outputs 1 when its inputs match
2020-02-27T16:53:41 < kakimir> true
2020-02-27T16:54:01 < kakimir> this has 2 bytes as input
2020-02-27T16:54:08 < kakimir> COMP_IO and IO
2020-02-27T16:54:22 < kakimir> mismatch between them and output is high
2020-02-27T16:54:30 < kakimir> it's a magnitude comparator
2020-02-27T16:54:45 < jpa-> isn't it just a misimplemented equality comparator?
2020-02-27T16:54:55 < jpa-> magnitude comparator would also handle negative values
2020-02-27T16:55:19 < kakimir> there is only equal or non-equal values
2020-02-27T16:55:31 < kakimir> and it is not misimplemented

2020-02-27T16:56:04 < jpa-> sorry, i must have mistought somehow

2020-02-27T16:56:55 < jpa-> there is HCT also if that is the logic levels you need
2020-02-27T16:57:13 < kakimir> HC chips have maximum propagation delay of 100ns or so
2020-02-27T16:57:23 < kakimir> and typical 20 or so

2020-02-27T16:57:59 < jpa-> so.. you expect your discrete logic to work at hundreds of megahertz?
2020-02-27T16:58:09 < kakimir> lvc = 1.0/2.5ns/4.0ns
2020-02-27T16:58:15 < kakimir> yes
2020-02-27T16:58:19 < kakimir> LVC does
2020-02-27T16:58:27 < kakimir> pretty high speeds
2020-02-27T16:58:37 < jpa-> 4 gates deep that is already 16 ns maximum
2020-02-27T16:59:33 < kakimir> not acceptable
2020-02-27T16:59:36 < kakimir> but
2020-02-27T16:59:48 < kakimir> it never goes 4gates deep to maximum in room temperature

2020-02-27T17:04:34 < jpa-> when the input values change, it will give spurious output pulses
2020-02-27T17:04:49 < kakimir> doesn't matter
2020-02-27T17:05:01 < kakimir> it's sampled with clock
2020-02-27T17:05:13 < jpa-> so, what is your clock speed?
2020-02-27T17:05:31 < kakimir> 25 million times a second
2020-02-27T17:05:52 < jpa-> why are you doing this with discrete logic anyway?

2020-02-27T17:06:38 < kakimir> because I can
2020-02-27T17:07:13 < BrainDamage> I hope your logic can handle metastable states
2020-02-27T17:07:24 < BrainDamage> because sampling at random will give you logic errors
2020-02-27T17:08:10 < kakimir> everything is settled at sampling time
2020-02-27T17:09:27 < jpa-> there is 8-input NAND (74LVC30) so you could use NXOR on the first level and then have the rest done in one step

2020-02-27T18:24:15 < jpa-> invzim: if you can get the data out from that, you can use pulseview to analyze / decode it - it also has direct support for some rigol scopes, but apparently not MSO5074 yet
2020-02-27T18:28:07 < jadew> bitmask, are you cooking meth?
2020-02-27T18:28:18 < bitmask> copper sulfate
2020-02-27T18:28:38 < jadew> ah, the color makes sense now
2020-02-27T18:29:48 < jadew> bitmask, why are you making that tho?
2020-02-27T18:30:07 < bitmask> I want to try electroplating
2020-02-27T18:30:15 < jadew> oh, neat
2020-02-27T18:30:22 < bitmask> specifically non conductive stuffs by first coating in graphite ink/paint
2020-02-27T18:30:23 < jadew> let me know how that goes
2020-02-27T18:30:27 < bitmask> will do
2020-02-27T18:30:43 < bitmask> like 3d prints, leaves, flowers
2020-02-27T18:30:58 < jadew> that sounds great
2020-02-27T18:33:12 < invzim> will have a poke next time I need serious LA then
2020-02-27T18:33:26 < invzim> got the original saleae thingie and it has served me very well for my needs so far
2020-02-27T18:34:27 < zyp> same
2020-02-27T18:34:35 < zyp> been a while since last I used it though
2020-02-27T18:34:38 < kakimir> jpa: not possible to do in 2 steps
2020-02-27T18:35:07 < kakimir> wait.. I checked only for 4-gate xnor

2020-02-27T18:49:49 < zyp> octavo killer: https://tibbo.com/store/plus1.html
2020-02-27T18:50:38 < karlp> you're like the third person to paste it over the last month or so now :)
2020-02-27T18:50:51 < zyp> oh, haven't seen it before
2020-02-27T18:50:54 < karlp> it's only killer if you want to work on the 8051 and the arm926 core
2020-02-27T18:51:02 < zyp> how so?
2020-02-27T18:51:02 < karlp> its definitely interesting though
2020-02-27T18:51:27 < zyp> what prevents you from ignoring those and only using the A7 cores?
2020-02-27T18:53:57 < karlp> it's the somewhat expensive? I mean, allwinner v3s is single core, and only 64MB, but is 1/4 the price: https://www.aliexpress.com/item/32837831495.html
2020-02-27T18:54:03 < karlp> even sam5a stuff
2020-02-27T18:54:33 < karlp> 512MB and quad core is nice I guess, for that niche
2020-02-27T18:55:28 < karlp> the power simplification is proably nice too.
2020-02-27T18:55:59 < zyp> I think it's more reasonable to compare it to the octavo, and as far as I can see it's both more capable and cheaper
2020-02-27T18:57:10 < karlp> sure, I guess compared to octavo itslef, you get a newer core, and cheaper
2020-02-27T18:57:32 < zyp> octavo has some stm32mp1 based stuff now

2020-02-27T22:49:59 < jadew> closest he came to him was about 20 meters, but he also went to his boss' house the next day after the italian
2020-02-27T22:50:00 < Steffanx> oh shit, people do get sick all the time.
2020-02-27T22:50:04 < jadew> so he might have picked it up from a surface
2020-02-27T22:50:10 < jadew> it's either aerosol or surface
2020-02-27T22:50:19 < Steffanx> or from another random guy sneezing into his face
2020-02-27T22:50:35 < Steffanx> such speculation
2020-02-27T22:50:47 < jadew> or that, they tested everyone who came in contact with the italian and the people those people came in contact with
2020-02-27T22:51:08 < jadew> and this guy drew the short stick
2020-02-27T22:51:20 < jadew> there's more to the story tho
2020-02-27T22:51:35 < jadew> he also visited Germany and came back like a week ago
2020-02-27T22:51:46 < jadew> maybe a little more than a week
2020-02-27T22:51:59 < BrainDamage> I guess people will avoid us like the plague from now on
2020-02-27T22:52:00 < jadew> but there's also that...
2020-02-27T22:52:10 < jadew> BrainDamage, for sure
2020-02-27T22:52:32 < BrainDamage> do you realize how stupid you sound, right?
2020-02-27T22:52:37 -!- emeb_mac [~ericb@ip68-2-65-72.ph.ph.cox.net] has joined ##stm32
2020-02-27T22:53:12 < Steffanx> No.
2020-02-27T22:53:29 < jadew> BrainDamage, why? you don't think people will be avoiding you until everyone gets it?
2020-02-27T22:53:35 < jadew> because I think they will and probably already are
2020-02-27T22:53:52 < BrainDamage> no, I think you're making a live feed of your fear and insecurity
2020-02-27T22:54:10 < BrainDamage> and yes, it's representative of what will happen in the future on average
2020-02-27T22:54:16 < jadew> in here, people who are known to have returned from Italy recently are being reported by their neighbours
2020-02-27T22:54:17 < BrainDamage> but it's not acceptable
2020-02-27T22:54:41 < jadew> BrainDamage, why not?
2020-02-27T22:55:01 < jadew> if everyone did this with the chinese, we wouldn't be in this mess
2020-02-27T22:55:15 < Cracki> :D
2020-02-27T22:55:28 < jadew> there's no reason not to keep things contained
2020-02-27T22:55:31 < Steffanx> Are we in a mess?
2020-02-27T22:55:35 < qyx> for sure
2020-02-27T22:55:38 < jadew> Steffanx, yeah
2020-02-27T22:55:41 < Steffanx> Media created mess for sure
2020-02-27T22:56:54 < BrainDamage> jadew: because you're panicking for every single event
2020-02-27T22:56:58 < jadew> Steffanx, I think the problem is that it takes too many resources to track everyone
2020-02-27T22:57:29 < BrainDamage> you're not different from those afraid of 'terrorism' and want to thoughtcrime everyone
2020-02-27T22:57:40 < jadew> at some point it becomes impossible to map out all the possible branches of the spread, so it gets loose and then we'll have to deal with it in a different way
2020-02-27T22:57:43 < BrainDamage> do you realize what means cutting off 1/7th of the world population?
2020-02-27T22:57:57 < jadew> BrainDamage, not for ever...
2020-02-27T22:58:22 < Cracki> what have you prepped yet
2020-02-27T22:58:22 < jadew> if they did the quarantine right for 30 days, we'd be back in business
2020-02-27T22:58:32 < Cracki> turn the panic into action
2020-02-27T22:58:49 < jadew> instead we're denying that this is spreading like wildfire and hoping for the best
2020-02-27T22:59:37 < jadew> Cracki, not much really
2020-02-27T22:59:51 < Cracki> go and do something :P
2020-02-27T22:59:55 < Cracki> buy food if you feel like it
2020-02-27T23:00:29 < Cracki> if nothing else happens, you'll have tons of (hopefully healthy) stuff that's ready to eat
2020-02-27T23:01:17 < Steffanx> Or when the super markets run out of food you can sell yours for BIG MUNNY.
2020-02-27T23:01:46 < qyx> so I need at least 4u7 caps for my AC coupling :(
2020-02-27T23:02:03 < zyp> what are you AC coupling?
2020-02-27T23:02:04 < Steffanx> Why is that :( ?
2020-02-27T23:02:07 < jadew> BrainDamage, and don't be fooled by what is being reported, I saw a TV show with head of the romanian CDC and he said something like: "The CFR is ~2.4%, which is much much lower than that of the seasonal flu" - which is a huge lie
2020-02-27T23:02:13 < qyx> zyp: 250k CAN
2020-02-27T23:02:27 < mawk> double free or corruption (fasttop)
2020-02-27T23:02:29 < mawk> fjsdoifjsdoifjsdoifds
2020-02-27T23:02:31 < mawk> I hate these bugs
2020-02-27T23:02:40 < mawk> I don't even manipulate a single pointer in the program how can this be possible
2020-02-27T23:02:43 < Steffanx> dont do that mawk
2020-02-27T23:02:51 < Steffanx> Use the fancy c++ features
2020-02-27T23:02:53 < zyp> qyx, ah
2020-02-27T23:02:58 < mawk> that's what I do
2020-02-27T23:02:59 < zyp> qyx, is that recommended?
2020-02-27T23:03:02 < mawk> I'm using shared_ptr
2020-02-27T23:03:04 < qyx> zyp: no.
2020-02-27T23:03:05 < mawk> that's why it's failing
2020-02-27T23:03:10 < Steffanx> Then you're doing it wrong
2020-02-27T23:03:12 < qyx> zyp: thats why I am failing
2020-02-27T23:03:19 < Steffanx> PHP would never do that mawk
2020-02-27T23:03:20 < mawk> can't debug that shit, the stack trace is 10 layers deep into template black magic
2020-02-27T23:03:20 < zyp> heh
2020-02-27T23:03:22 < qyx> Steffanx: of course

2020-02-27T23:04:03 < qyx> Ich parke nicht francais
2020-02-27T23:04:10 < zyp> probably a better solution
2020-02-27T23:04:15 < qyx> *parle, sorry
2020-02-27T23:04:17 < Steffanx> ç
2020-02-27T23:04:25 < mawk> çççéàé
2020-02-27T23:04:26 < BrainDamage> is it just me that when you read can trasceiver think of strings connecting tin cans?
2020-02-27T23:04:33 < zyp> yes
2020-02-27T23:04:45 < zyp> but thanks for the mental picture
2020-02-27T23:05:01 < mawk> I'm not doing it wrong it's designed not to fail in theory Steffanx 
2020-02-27T23:05:09 < mawk> using RAII you have absolute guarantees
2020-02-27T23:05:14 < mawk> to only way to fuck it up is use pointers manually
2020-02-27T23:05:30 < Steffanx> maw if it's by design, then its not a bug. 
2020-02-27T23:05:32 < qyx> zyp: yeah isolators would be ideal but consume too much current
2020-02-27T23:05:33 < zyp> RAII is fine
2020-02-27T23:05:36 < mawk> broken by design
2020-02-27T23:05:41 < jadew> like this? https://previews.123rf.com/images/aleksanderdn/aleksanderdn1601/aleksanderdn160100004/50839278-tin-cans-telephone-isolated-on-white-background-3d.jpg

2020-02-27T23:57:36 < jadew> lots of rats are going to give their lives for this cause
2020-02-27T23:59:08 < jadew> there should be a statue of a rat and a monkey in every town

--- Day changed Fri Feb 28 2020

2020-02-28T00:01:24 < jadew> I mean it... there should really be a statue to celebrate these poor creatures
2020-02-28T00:02:12 < specing> BrainDamage: precisely why
2020-02-28T00:02:50 < Laurenceb> wew
2020-02-28T00:03:07 < Laurenceb> neighbours daughter has been sent to a hotel by the biohazard suit guys
2020-02-28T00:03:11 < Laurenceb> crazy shit 
2020-02-28T00:03:34 < BrainDamage> are you going to be tested?
2020-02-28T00:03:36 < jadew> it was nice meeting you
2020-02-28T00:03:40 < Cracki> hotel... i'd just put up container castles. you can hose that down easier.
2020-02-28T00:03:54 < Laurenceb> keek
2020-02-28T00:04:08 < Cracki> it's ok, you can admit if you had contact with her
2020-02-28T00:04:08 < Laurenceb> BrainDamage: nah I havent been near her
2020-02-28T00:04:13 < Laurenceb> lol
2020-02-28T00:04:42 < Laurenceb> the biohazard guys were round taking samples from his house earlier
2020-02-28T00:04:42 < jadew> her bathroom window was always between you two?
2020-02-28T00:04:46 < Laurenceb> lel
2020-02-28T00:05:13 < jadew> it's good to hear they're taking it seriously
2020-02-28T00:05:16 < Laurenceb> itshappening.gif
2020-02-28T00:05:40 < BrainDamage> strange how you're not complaining that they're doing it wrong and you have a sim how you can do it 10x better
2020-02-28T00:05:43 < Cracki> seriously would be if they put the whole family and her class under house arrest
2020-02-28T00:06:15 < jadew> BrainDamage, me or Laurenceb?
2020-02-28T00:06:23 < BrainDamage> Laurenceb
2020-02-28T00:06:46 < jadew> Cracki, they probably are
2020-02-28T00:06:49 < jadew> this is how they do it here
2020-02-28T00:06:59 < jadew> but it's not house arrest, it's isolation
2020-02-28T00:07:05 < jadew> with military guard :P
2020-02-28T00:07:09 < Cracki> >_>
2020-02-28T00:07:13 < Laurenceb> aiui the school is closed and the other teachers have been sent to the hotel
2020-02-28T00:07:28 < Cracki> "sent to the hotel" sounds ominous
2020-02-28T00:07:30 < Laurenceb> lol
2020-02-28T00:07:40 < Laurenceb> one of the teachers caught the virus in Italy aiui

2020-02-28T00:16:00 < jadew> bottom left
2020-02-28T00:16:02 < nn7> it's an stm32f411
2020-02-28T00:16:14 < nn7> jadew, how can you tell?
2020-02-28T00:16:21 < jadew> the silkscreen is different
2020-02-28T00:16:29 < karlp> read the datasheet again
2020-02-28T00:16:37 < karlp> it includes the text orientation.
2020-02-28T00:16:55 < nn7> jadew, that doesn't help. I need to know on the chip
2020-02-28T00:17:10 < nn7> karlp, ah, on the previous page. Thanks!
2020-02-28T00:17:16 < BrainDamage> small and deep is the real pin 1 marker anyway
2020-02-28T00:17:36 < BrainDamage> the large and flat is the mold pouring dip
2020-02-28T00:17:40 < karlp> nn7: as you can guess, you're not the first :)

2020-02-28T00:17:44 < jadew> why wouldn't they mix them tho?
2020-02-28T00:17:47 < Laurenceb> hypeberry
2020-02-28T00:18:23 < karlp> well, doubling the ram at the price is a nice update
2020-02-28T00:18:44 < karlp> it's still a weird shitty  broadcom world of unobtainium, but.. you can certainly get things done with it.
2020-02-28T00:18:49 < BrainDamage> well, it's more like the previous price was overcharging than the 4 is a fantastic deal
2020-02-28T00:19:05 < BrainDamage> rather rpi4 is finally in line with the rest of the market like odroids
2020-02-28T00:19:20 < karlp> it's noticeably cheaper now isn' tit?
2020-02-28T00:19:43 < BrainDamage> than what?
2020-02-28T00:19:52 < Laurenceb> now if they added rtc and proper power management...
2020-02-28T00:20:03 < Laurenceb> coming... never
2020-02-28T00:20:08 < karlp> well, a C2 is $46.
2020-02-28T00:20:13 < karlp> what would you compare it tooÐ?
2020-02-28T00:20:30 < BrainDamage> a c2 is a good point of comparison
2020-02-28T00:20:36 < BrainDamage> and also few years old
2020-02-28T00:20:56 < BrainDamage> 4 years old
2020-02-28T00:21:06 < BrainDamage> so now they are competitive with a 4 years old product
2020-02-28T00:21:31 < karlp> well, c2 has no wifi or bt, and is ~30%ish more expensive too, despite having had 4 years to get cheaper...
2020-02-28T00:21:54 < karlp> and if you're buying "a computer to put in a cupboard" it doesn't amtter how old it is really...
2020-02-28T00:22:21  * karlp shrugs.  I have a c2, and an rpi1, a few allwinning parts.  the rpi1 is the only thing that doesn't get used :)
2020-02-28T00:22:30 < BrainDamage> I use the rpi1 too
2020-02-28T00:22:38 < BrainDamage> I have a ntp server
2020-02-28T00:22:45 < karlp> I'm just not excited about sd card root file systems :)
2020-02-28T00:22:50 < jadew> I use a rpi2 for old games
2020-02-28T00:23:00 < BrainDamage> just plug a usb gps and plug the pps in a gpio
2020-02-28T00:23:06 < zyp> I have a rpi4 that I haven't used for anything yet
2020-02-28T00:23:47 < zyp> actually, the thing I wanted to use it for was what sparked off the whole backplane project
2020-02-28T00:23:50 < BrainDamage> since I was there I also added a dcf77 receiver and now I'm trying to measure weather through time signal delay
2020-02-28T00:24:00 < BrainDamage> +change
2020-02-28T00:24:01  * karlp has been a bit burnt with rockchip crap honestly.
2020-02-28T00:24:51 < BrainDamage> at the very least I can tell when a thunderstorm approaches because it jams the dcf link >.>
2020-02-28T00:24:53 < karlp> does pi4 have usb otg or do you still need a zero for that?
2020-02-28T00:25:13 < zyp> I believe the usb-c port is still power only
2020-02-28T00:25:19 < zyp> and the rest are A ports, so no OTG

2020-02-28T01:07:11 < zyp> that looks like the shit you'd mold over
2020-02-28T01:07:47 < zyp> or solder a cable to
2020-02-28T01:07:50 < zyp> and mold over
2020-02-28T01:08:01 < karlp> oh totally, 
2020-02-28T01:08:11 < karlp> I mean, I get what it's for, just not for me right now :)
2020-02-28T01:08:11 < zyp> ah, yes
2020-02-28T01:08:43 < zyp> it's not even rated for reflow, good luck getting a board attached
2020-02-28T01:08:55 < karlp> I'm _actually_ workign on my hub project again, first time in at least a month I guess.
2020-02-28T01:09:35 < zyp> I'm about to see if I can track down a segfault in nextpnr
2020-02-28T01:10:16 < karlp> nice :)
2020-02-28T01:10:38 < karlp> I have absolutely nothign on my desk, it's absolutely sterile and feels weird.
2020-02-28T01:10:54 < karlp> had real-estate photographers this afternoon and it's all been staged.
2020-02-28T01:10:58 < BrainDamage> jaden would approve
2020-02-28T01:11:00 < zyp> it's just the gui mode segfaulting when I'm trying to load a file
2020-02-28T01:11:21 < zyp> actual placing and routing works fine, but it'd be fun to be able to see what it does too
2020-02-28T01:11:41 < karlp> BrainDamage: nah, I'm going to be inviting strangers into my home in a few days, and inviting them to poke around and touch things. jade would _not_ approve :)
2020-02-28T01:12:03 < zyp> haha
2020-02-28T01:12:47 < jadew> you are correct, I would not :P
2020-02-28T01:13:21 < karlp> jadew: well, I'm doing it today, before there's any reports in .is, so that I can have a bigger house to bunker down in for the rest of the year? is that ok?
2020-02-28T01:13:50 < jadew> yeah, that seems like a good plan

2020-02-28T01:14:51 < Steffanx> Good bye karlp  
2020-02-28T01:16:40 < qyx> how should a WWAN LED on a 3G modem behave
2020-02-28T01:16:51 < qyx> it is just being lit
2020-02-28T01:17:41 < jadew> qyx, is it lit green or red?
2020-02-28T01:18:07 < jadew> generally, if it's blinking, something's happening
2020-02-28T01:18:16 < jadew> if it's lit green, it's ok
2020-02-28T01:18:26 < qyx> if I solder a red LED, it is red
2020-02-28T01:18:35 < qyx> generally, it is lit in a color of the LED I solder
2020-02-28T01:18:54 < qyx> more specifically, now it is red
2020-02-28T01:19:21 < jadew> if you're making the thing, then you should probably make it green, otherwise people will assume it's not working
2020-02-28T01:19:25 < qyx> but in all seriousness, it waits few seconds probably while the modem is booting
2020-02-28T01:19:38 < qyx> and then it stays constantly on
2020-02-28T01:20:43 < qyx> omega2s is coming tomorrow, I'll see whats going on if USB works

2020-02-28T01:26:29 < qyx> except tom66's soldering job
2020-02-28T01:26:41 < qyx> but otherwise it seems to work nicely

2020-02-28T03:15:15 < karlp> still on the nextpnr segfault?
2020-02-28T03:15:59 < zyp> yeah
2020-02-28T03:16:15 < zyp> this is fucking weird
2020-02-28T03:16:34 < karlp> bitmask: cool crystals, if you buy it commerically, you get much finer cryustals, it's like blue crunchy sand, not crystally like yours
2020-02-28T03:17:02 < karlp> well, checked some footprints, assigned models... laid..... zero traces. progress?
2020-02-28T03:17:16 < zyp> https://github.com/YosysHQ/nextpnr/blob/master/gui/treemodel.cc#L96 <- it's segfaulting because the compare function gets passed a corrupt pointer
2020-02-28T03:17:48 < zyp> the vector it's sorting contains perfectly good pointers before the sort
2020-02-28T03:17:50 < karlp> what's rad i s that the datasheet from lcsc has one recommended footprint, the one from the vendor is different
2020-02-28T03:18:19 < karlp> why lldb though?
2020-02-28T03:18:25 < zyp> macos
2020-02-28T03:18:28 < karlp> is that the only  option for host debugs on macos then?
2020-02-28T03:18:48 < zyp> dunno, it's the default one at least
2020-02-28T03:19:07 < karlp> is that making a lambda closure thingy for the sort function?
2020-02-28T03:19:23  * karlp isn't a c++<anyverison> expert
2020-02-28T03:19:29 < zyp> not sure how much it'd help anyway, I'm printf-debugging this shit now

2020-02-28T03:20:05 < karlp> I'm goign to bed. late late.
2020-02-28T03:20:18 < zyp> it looks like stack corruption, but I can't find anything that can corrupt the stack
2020-02-28T03:20:33 < zyp> so I don't know what the fuck is going on
2020-02-28T03:21:30 < karlp> covid infection :)
2020-02-28T03:22:01 < kakimir> use freertos-mpu

2020-02-28T03:23:32 < zyp> memory protection traps you when you try dereferencing trash on the stack, not when you're putting trash on the stack

2020-02-28T05:17:58 < fenugrec> say I want to feed the CRC peripheral from DMA; the CRC takes "4 AHB cycles per 32-bit block". Is it possible for the DMA periph to overrun this ? Probably not since DMA is limited to <50% of AHB time, and it takes at least 2 cycles to read mem + write to CRC_DR. Sounds sane ?
2020-02-28T05:20:05 < upgrdman> guessing part of the DMA engine is the signaling for data ready between periphs
2020-02-28T05:20:15 < upgrdman> so i doubt you'll overflow
2020-02-28T05:22:07 < zyp> how is DMA limited to 50% of AHB time? you mean due to bus contention?
2020-02-28T05:23:40 < zyp> I believe there's a crossbar so the cpu might very well be accessing other stuff leaving DMA a free path to the CRC periph
2020-02-28T05:26:16 < fenugrec> zyp, I may be misinterpreting the RM, "scheduling [...] ensuring at least half of the system bus bandwidth (both to memory and peripheral) for the CPU."
2020-02-28T05:26:26 < zyp> but isn't this easy enough to test in practice? start a timer, start a big DMA job, set CPU in WFI to minimize bus contention, wait for DMA job to finish, check elapsed time and valid CRC
2020-02-28T05:26:59 < fenugrec> the CRC chapter doesn't even mention DMA, so I'm not sure there's special signaling there. Yes, easy to test, but I'm armchair-coding atm
2020-02-28T05:27:37 < upgrdman> you'd be doing memory-to-periph DMA. iirc, you have to indicate which periph? its been a while since i last did stm32 dma...
2020-02-28T05:27:57 < zyp> I'd expect it to work, and if it doesn't, you can have a timer trigger the DMA at a slower rate instead of using M2M mode
2020-02-28T05:29:09 < fenugrec> Hum. " An input buffer allows to immediately write a second data without waiting for any wait states due to the previous CRC calculation."
2020-02-28T05:29:50 < fenugrec> yeah, "probably ok".
2020-02-28T05:31:06 < fenugrec> upgrdman, nah, CRC isn't selectable in the DMA registers, so it would have to be M2M

2020-02-28T11:48:56 < jpa-> ah, with std::sort
2020-02-28T11:49:12 < jpa-> yeah, many sort algorithms fail in funny ways when comparison function is broken :)
2020-02-28T11:49:48 < karlp> in js or lua you just get unstably sorted, not "hah haa fuck you!"
2020-02-28T11:52:31 < jpa-> that's nice if it can't even infinite loop on messed up comparison
2020-02-28T11:55:32 < karlp> lua: love.lua:8: invalid order function for sorting
2020-02-28T11:55:46 < karlp> that's with standard lua table.osrt
2020-02-28T11:55:55 < karlp> I thought I saw something else, maybe in penlight ou got unstable sort
2020-02-28T11:56:27 < jadew> karlp, "hah haa fuck you!" is the more useful behaviour tho
2020-02-28T11:56:41 < jpa-> assert() would be fine
2020-02-28T11:56:45 < karlp> no, "invalid order function for sorting" is way better.
2020-02-28T11:56:50 < karlp> or assert 
2020-02-28T11:56:57 < karlp> anythign other than "somewhere my code segfaulted"
2020-02-28T11:56:58 < jpa-> but segfaults are not guaranteed to segfault, could just mess up data randomly
2020-02-28T11:57:40 < karlp> ok, lua table.sort is't guaranteed to be stable for equal elements, that's what I was remembering
2020-02-28T11:59:43 < karlp> https://paste.jvnv.net/view/AQDf3 for the curious
2020-02-28T12:01:39 < jadew> how does it detect that?
2020-02-28T12:01:51 < karlp> dont' care. far better behaviour
2020-02-28T12:01:58 < jadew> is it testing the function before using it?
2020-02-28T12:03:00 < karlp> js doesn't crash, just gives you poorly sorted.
2020-02-28T12:03:29 < jadew> tbh, I don't understand why c++ would crash either
2020-02-28T12:03:55 < BrainDamage> well, stdlib is open source, you can just look at it
2020-02-28T12:03:55 < karlp> https://paste.jvnv.net/view/MFOMh for js.
2020-02-28T12:04:09 < jadew> BrainDamage, was just going to, yeah
2020-02-28T12:04:18  * karlp chalks up a victory for lua and goes back to it...
2020-02-28T12:07:52 < jadew> compiled that with VS2019 and got a nice failed assertion
2020-02-28T12:08:02 < jadew> "invalid comparator"
2020-02-28T12:10:47 < karlp> nice.
2020-02-28T12:10:56 < karlp> one for dongs, better use windows :)
2020-02-28T12:12:08 < jadew> I think all FFP3 masks are gone
2020-02-28T12:12:14 < jadew> including some of the ones from the future
2020-02-28T12:13:07 < jadew> I talked to a distributor yesterday, trying to get some for a few friends that are exposed more than other people and the distributor said that there's no way I can get FFP3 masks anytime soon
2020-02-28T12:13:32 < jadew> the Romanian government alone ordered 6 million masks
2020-02-28T12:13:39  * karlp finds it absurd that you're only just getting onto this
2020-02-28T12:14:00 < PaulFertser> jadew: are you talking about full face masks, covering eyes too?
2020-02-28T12:14:20 < jadew> karlp, I was aware of the situation, but I'm pointing out that the shortage might last a little longer
2020-02-28T12:14:29 < jadew> PaulFertser, no, disposable ones
2020-02-28T12:14:58 < PaulFertser> jadew: eh, how to protect the eyes then?
2020-02-28T12:15:04 < jadew> glasses
2020-02-28T12:15:08 < karlp> PaulFertser: stop bringing logic into things...
2020-02-28T12:15:37 < jadew> those glasses you can find at the hardware store are reasonably good at keeping things away from your eyes
2020-02-28T12:15:37 < PaulFertser> jadew: like a mask for snowboarding?
2020-02-28T12:15:42 < jadew> including aerosols
2020-02-28T12:16:08 < jadew> not 100%, but better than other types of glasses
2020-02-28T12:17:20 < PaulFertser> jadew: why not order this from official distributor: https://www.3mrussia.ru/3M/ru_RU/company-ru/all-3m-products/~/3M-6800-%D0%9F%D0%BE%D0%BB%D0%BD%D0%B0%D1%8F-%D0%9C%D0%B0%D1%81%D0%BA%D0%B0-%D1%81%D0%B5%D1%80%D0%B8%D0%B8-3%D0%9C-6000-%D1%80%D0%B0%D0%B7%D0%BC%D0%B5%D1%80-%D1%81%D1%80%D0%B5%D0%B4%D0%BD%D0%B8%D0%B9-M-/?N=5002385+3292817024&rt=rud
2020-02-28T12:17:35 < jadew> 404
2020-02-28T12:17:43 < jadew> but I know the model
2020-02-28T12:17:49 < PaulFertser> Or UNIX 5100
2020-02-28T12:18:21 < PaulFertser> Here's an extensive overview with some reasonable rationale: https://habr.com/ru/post/487176/
2020-02-28T12:18:33 < jadew> I think a lot of folks that are exposed would wear that, but they don't want to frighten to people they work with
2020-02-28T12:18:51 < PaulFertser> The glasses need to be airtight anyway....
2020-02-28T12:18:52 < jadew> so they'd rather use disposable FFP2/3 masks + glasses
2020-02-28T12:19:16 < PaulFertser> Why not proper mask plus disposable filters?
2020-02-28T12:19:32 < PaulFertser> 3M 7500
2020-02-28T12:19:34 < jadew> PaulFertser, because you'd look like you're just coming from outer space
2020-02-28T12:19:59 < PaulFertser> jadew: but you need reliable protection. Decent mask allows proper inspection, disinfection etc. And you just change the filter.
2020-02-28T12:20:11 < jadew> PaulFertser, I'm aware
2020-02-28T12:20:22 < jadew> they wouldn't wear that tho
2020-02-28T12:21:05 < BrainDamage> it's about deceiving one self that you're doing something meaningful, not the result
2020-02-28T12:21:08 < PaulFertser> That's just weird. Either they need protection or not.
2020-02-28T12:21:28 < PaulFertser> Or are they into "fashion statements" rather than logic?
2020-02-28T12:21:46 < BrainDamage> no, it's just an outlet for anxiety
2020-02-28T12:21:46 < jadew> PaulFertser, well, wearing a FFP3 mask + protective glasses, is definitely better than nothing
2020-02-28T12:22:11 < jadew> and you don't scare patients away either
2020-02-28T12:22:14 < PaulFertser> jadew: how long are they going to stay in an airtight glasses?
2020-02-28T12:22:31 < jadew> 8h/day
2020-02-28T12:23:07 < jadew> I assume that if the danger becomes imminent, they would switch to whatever, but so far, it's just a precaution
2020-02-28T12:23:36 < PaulFertser> I expect them to start neglecting on a second day or so.
2020-02-28T12:24:18 < jadew> even so, it still reduces the odds of catching something, just like a surgical mask does, even if it's not particularly good at it
2020-02-28T12:26:24 < PaulFertser> Following special routine each time they need to wear the this equipment is unlikely I'd say.
2020-02-28T12:27:07 < jadew> eh, it's not that difficult to sanitize your hands before and after putting the mask on or taking it off

2020-02-28T12:27:32 < jadew> but yeah, I know what you're saying
2020-02-28T12:27:55 < BrainDamage> wearing gloves would be easier
2020-02-28T12:27:58 < PaulFertser> https://hsto.org/webt/y2/2i/fl/y22iflawqm2zbtsaj9x5kyb1oww.jpeg even just taking the gloves properly is tricky!
2020-02-28T12:28:41 < BrainDamage> that's how I've always took them of
2020-02-28T12:28:42 < jadew> personally I'm an expert at taking gloves off
2020-02-28T12:29:14 < jadew> but I'm not doing it like that
2020-02-28T12:29:23 < jadew> I take one half off
2020-02-28T12:29:34 < jadew> then I grab the other one with half still on
2020-02-28T12:29:34 < BrainDamage> I've had my share of chemical experiments and touching the residue on gloves was always a concern
2020-02-28T12:29:41 < jadew> and when I take it off, they go inside out
2020-02-28T12:29:50 < jadew> and one of them enters the other
2020-02-28T12:30:04 < jadew> so they're safe to touch on every part that is exposed
2020-02-28T12:30:39 < PaulFertser> Are you friends experts at that too?

2020-02-28T12:31:32 < jadew> oh, I get it, but I still think it's better than nothing
2020-02-28T12:31:48 < jadew> maybe some spit lands on the mask, rather than on your lips
2020-02-28T12:32:07 < jadew> same with the eyes
2020-02-28T12:32:41 < BrainDamage> it depends on the minimum amount of virus for contagion
2020-02-28T12:32:57 < BrainDamage> some sickness require thousand of elements, some are insane and even 1-2 are sufficient
2020-02-28T12:33:16 < BrainDamage> for the latter, any improper protection is essentially meaningless
2020-02-28T12:33:48 < jadew> right, I've heard somewhere that not all virus copies match your organism, which is why there have to be more - that's what you're referring to, right?

2020-02-28T12:34:50 < jadew> this is probably something that is in tight correlation with the rate of spread
2020-02-28T12:35:49 < BrainDamage> it's a generic modeling from microbiology, it abstract the infection type, there's several mechanisms at play
2020-02-28T12:36:11 < BrainDamage> epigenetic resistance, mechanism of infection, etc
2020-02-28T12:37:29 < PaulFertser> jadew: are you friends working in hospital? Why do you think it's not enough to follow the WHO advice for medical personnel?
2020-02-28T12:37:50 < jadew> PaulFertser, they're pharmacists
2020-02-28T12:38:00 < Steffanx> Lol jadew woke up.

2020-02-28T12:38:21 < jadew> I woke up earlier, but I had some business to take care of :P
2020-02-28T12:38:26 < PaulFertser> jadew: so do they consider WHO guidelines inadequate?
2020-02-28T12:39:07 < jadew> PaulFertser, the WHO guidelines being what?
2020-02-28T12:39:35 < jadew> the govt message is that healthy people shouldn't wear any mask, unless in the presence of infected people
2020-02-28T12:39:51 < jadew> thing is, even if that was a good message, as a pharmacists, you don't know how is sick and who isn't
2020-02-28T12:40:24 < PaulFertser> jadew: don't they just read the guidelines on the official WHO website? Do they trust Romanian government more than WHO?
2020-02-28T12:40:25 < jadew> people could go there for any number of reasons, way before they figure out that they should go to the hospital or get tested
2020-02-28T12:40:39 < jadew> PaulFertser, I don't think they trust either
2020-02-28T12:41:11 < jadew> WHO, is at fault for much of the spread, because they were over cautions in their advice
2020-02-28T12:41:52 < PaulFertser> jadew: https://apps.who.int/iris/rest/bitstreams/1269003/retrieve

2020-02-28T12:51:00 < jadew> it is
2020-02-28T12:51:02 < benishor> my wife's a medic
2020-02-28T12:51:12 < benishor> and yet I don't have an army of medics
2020-02-28T12:52:08 < jadew> all our friends from her side are either pharmacists or medics
2020-02-28T12:52:19 < jadew> and we're even related with some of them now
2020-02-28T12:52:42 < jadew> well, not all, but most
2020-02-28T12:52:51 < benishor> smells like the start of a cult
2020-02-28T12:53:10 < jadew> heh

2020-02-28T12:54:48 < jadew> "not all, but most" - was referring how most of them are pharmacists, not how most of them are related to us

2020-02-28T13:02:45 < jadew> oh

2020-02-28T13:29:25 < benishor> jadew: to put it gently, I am more panicky than my wife is
2020-02-28T13:29:45 < benishor> she has a decent amount of worry but not excessive
2020-02-28T13:30:38 < benishor> needless to say we made stocks of medicine and disinfectant
2020-02-28T14:37:59 < zyp> karlp, I guess it's undefined behavior for the same reason anything else in C++ is; speed
2020-02-28T14:45:01 < karlp> sure, but it'd be nice if you get a warning that undefined behaviour has been used to make those gains.
2020-02-28T14:45:04 < karlp> at _least_
2020-02-28T14:45:49 < karlp> and even with -O0 it still segfaults.
2020-02-28T14:46:17 < karlp> so really, this is just shitty behaviour of g++ IMO, given that vs2019 will tell you outright, "busted compare"
2020-02-28T14:52:56 < karlp> clang++ doesn't care either
2020-02-28T14:53:19 < zyp> will tell you, runtime?
2020-02-28T14:53:22 < zyp> or compile time?
2020-02-28T14:55:15 < zyp> if it's a compile time warning, it's subject to how good the static analyzer is, and the actual compare function I were debugging is a bit more complex

2020-02-28T15:11:39 < karlp> go furthe to the c++ one that simply segfaults :)
2020-02-28T15:19:58 < benishor> all the checks take time
2020-02-28T15:25:38 < karlp> sure, and segfaults are "fast"
2020-02-28T15:34:09 < benishor> sure they are. the fastest code is the one that never runs
2020-02-28T15:34:19 < benishor> that's what you get if you write a bad comparator :)
2020-02-28T15:46:44 < karlp> sure you're in italy, and not stockholm?

2020-02-28T15:56:03 < upgrdman> gpu pros: my web browser (chrome) can easily handle a 4k20 MJPEG stream and display it full screen with about 22% cpu usage and 24% gpu usage on my pc. if i write software to decode the jpeg on cpu and then transfer it to an opengl texture and draw it on screen, i'm severely bottlenecked by the cpu decoding. takes 65-85ms per frame. anyone know what the browser people do? guessing they use the gpu to decode the jpegs? but anyone KNOW if 
2020-02-28T15:56:04 < upgrdman> that's the case, or maybe they use a faster cpu decoder? not sure where in the chromium (or other browser) source code to look and see.
2020-02-28T16:11:15 < Ultrasauce> whats your target platform
2020-02-28T16:14:07 < Ultrasauce> chrome/ium definitely targets multiple hardware acceleration apis, both directly and via ffmpeg

2020-02-28T16:47:29 < upgrdman> Ultrasauce, using android as a wifi webcam. the apps i've found just expose mjpeg over http.
2020-02-28T16:48:14 < upgrdman> which for me is good, since i just want to funnel image data into my TelemetryViewer program, so this might be more efficient to decode than h265 or whatever. or not?
2020-02-28T16:49:07 < upgrdman> mjpeg is definitely helpful sicne the frame are independant. i can rewind time without having to render all frames since last keyframe, etc.
2020-02-28T16:49:51 < Ultrasauce> more efficient is doubtful but that usecase is compelling yeah
2020-02-28T16:49:59 < upgrdman> k
2020-02-28T16:50:16 < Ultrasauce> if i had to guess, the cpu->gpu transfer is as bad for perf as the software decoding
2020-02-28T16:50:55 < Ultrasauce> but eliminating that in windows probably would require switching to dx

2020-02-28T16:51:44 < Ultrasauce> honestly the low hanging fruit here is probably just decreasing the resolution
2020-02-28T16:52:21 < upgrdman> when profiling, sending the uncompressed R8G8B8 bytes to the gpu is plenty fast. main bottle neck is cpu decode speed, and on my weaker laptop, the pixel fill rate is a minor bottleneck but not critical
2020-02-28T16:53:06 < upgrdman> ya. but i want muh 4k :) i can easily work around by using threads to decode multiple frames in parallel, and display them with a little latency. but would perfer not to do that.
2020-02-28T16:53:39 < jpa-> upgrdman: what jpeg decoder are you using? there is a lot of variation between different libraries
2020-02-28T16:54:12 < upgrdman> it looks like the java opengl lib im using has some helper classes to import a jpeg into an opengl texture, and they wrote their own jpeg decoder. guess i should try it and see if it's faster. looks to be all on cpu, but maybe its better.
2020-02-28T16:54:17 < jpa-> chromium can use hardware-specific mjpeg accelerators
2020-02-28T16:54:56 < Ultrasauce> lol is it a decoder written in java
2020-02-28T16:55:16 < upgrdman> jpa-, right now i just tried the one built into java "ImageIO.read()"
2020-02-28T16:55:45 < upgrdman> Ultrasauce, inorite. but with modern jvm's, the JIT compilers are decent

2020-02-28T18:18:18 < zyp> no, HNP/SNP is OTG role swap
2020-02-28T18:18:30 < zyp> not sure it's relevant anymore now with USB-C
2020-02-28T18:18:37 < nn7> I see. OK thanks.
2020-02-28T18:18:53 < zyp> but backtrack a bit, what is the context here?
2020-02-28T18:19:09 < zyp> all OTG capable stm32s have built in DP pull-up
2020-02-28T18:19:09 < nn7> I have a board I just made and I'm having trouble getting USB bootloader showing up as a valid device in Windows.
2020-02-28T18:19:09 < karlp> still pretty relelvant if you'r enot using usb-c dude :)
2020-02-28T18:19:17 < karlp> except that does anyone every do it anyway?
2020-02-28T18:19:33 < zyp> karlp, who the fuck does OTG on anything but usb-c nowadays?
2020-02-28T18:19:33 < karlp> does it have a rom dfu bootloader? can you enter that?
2020-02-28T18:19:44 < nn7> that's what I'm trying to get to.
2020-02-28T18:19:49 < nn7> But I think I saw it work once.
2020-02-28T18:19:52 < karlp> zyp: anyone with existing hardware?
2020-02-28T18:20:03 < nn7> I've hooked up an external stlinkv2 and the chip is alive and happy
2020-02-28T18:20:17 < karlp> scribus crashes trying to insert a unicode +- char. good job.
2020-02-28T18:20:38 < nn7> I have 22 ohm resistors on both data lines and a 1.5k pull-up on DP
2020-02-28T18:21:09 < zyp> remove the 1.5k pull up
2020-02-28T18:21:17 < zyp> that's internal
2020-02-28T18:21:33 < nn7> Is that a change from the F303 to the F411?
2020-02-28T18:21:55 < zyp> it's a change between the device-only and the OTG-capable usb peripherals
2020-02-28T18:22:46 < Thorn> do you ever need external pullups with stm32?
2020-02-28T18:23:03 < nn7> now Windows doesn't see the device at all
2020-02-28T18:23:10 < Thorn> I've never needed one with any type of usb core
2020-02-28T18:23:12 < nn7> (after removing the 1.5k)
2020-02-28T18:23:35 < zyp> Thorn, yes, the ones with v1 of the device only core doesn't have internal pullup
2020-02-28T18:23:42 < zyp> v2 does
2020-02-28T18:24:07 < zyp> i.e. anything otg-capable and anything from f0 on and newer won't need an external pullup
2020-02-28T18:24:27 < zyp> f1/f3 and l1 IIRC will need an external pullup
2020-02-28T18:24:42 < Thorn> oh ok that's possible, I don't think I've ever tried to being usb up on f103 or something as old
2020-02-28T18:24:46 < zyp> except f3 has a weird split where some parts got v1 and some parts got v2
2020-02-28T18:24:48 < Thorn> *bring
2020-02-28T18:24:58 < nn7> ok. I removed the 1.5k and now windows doesn't notice the device being plugged in.
2020-02-28T18:25:15 < nn7> plugging in an stlink verifies the device is alive.
2020-02-28T18:25:26 < zyp> that explains why windows couldn't recognize the device type before
2020-02-28T18:25:55 < zyp> if the internal pullup is not enabled, you're probably not running any usb-firmware that would handle requests
2020-02-28T18:26:10 < nn7> I have the boot jumper installed
2020-02-28T18:26:10 < Thorn> nn7: do you have enough of the driver implemented to enumerate?
2020-02-28T18:26:16 < zyp> so external pullup makes windows see there's a device, but it doesn't reply
2020-02-28T18:26:24 < Thorn> or are you trying to use dfu bootloader?
2020-02-28T18:26:26 < zyp> nn7, do you have a crystal?
2020-02-28T18:26:39 < nn7> I have an 8mhz resonator
2020-02-28T18:27:05 < zyp> are you able to try whether the serial bootloader works?
2020-02-28T18:27:28 < nn7> How would I accomplish that?
2020-02-28T18:27:43 < zyp> hook up to a uart, see if it answers
2020-02-28T18:27:58 < zyp> i.e. the uart that the bootloader uses

2020-02-28T20:03:50 < kakimir> is there stm32 chips with fifo usb endpoint and external fifo port + control logic to drive ie. sram with that fifo?
2020-02-28T20:04:21 < kakimir> to say: like fx2 but stm32
2020-02-28T20:05:03 < zyp> f4?
2020-02-28T20:05:56 < kakimir> it has logic to control we and oe and increment fifo pointer?
2020-02-28T20:06:24 < zyp> the OTG_HS instance includes DMA, and if you hook up SRAM or whatever to FSMC I believe you should be able to have the usb core DMA directly into or out from it
2020-02-28T20:06:47 < kakimir> also reflect fifo address to external pins.. I expect 9 or more
2020-02-28T20:07:00 < zyp> no.
2020-02-28T20:07:30 < zyp> the usb core and FSMC are independent things, you'll have to provide some software glue yourself
2020-02-28T20:07:56 < kakimir> it's not about software if I want incrementing address lines
2020-02-28T20:07:58 < nn7> A 7.5k pull-up on NRST is ok?
2020-02-28T20:08:03 < kakimir> it just is or isn't
2020-02-28T20:08:06 < kakimir> nn7: yes
2020-02-28T20:08:20 < nn7> I'm really confused why my STM doesn't seem to be going into bootloader mode
2020-02-28T20:08:23 < zyp> ah, if you just want incrementing then that's no problem
2020-02-28T20:08:47 < zyp> FSMC basically maps an external SRAM into the internal memory map
2020-02-28T20:09:02 < zyp> and the USB DMA will write sequentially into that
2020-02-28T20:09:26 < kakimir> write and read no problem?
2020-02-28T20:09:41 < kakimir> what kind of performance to expect?
2020-02-28T20:10:21 < kakimir> I think fx2 could do 24M writes per second or 48M reads per second
2020-02-28T20:10:50 < zyp> I haven't used USB DMA, but I've had the CPU shovel data from USB to FSMC
2020-02-28T20:10:51 < zyp> https://paste.jvnv.net/view/AkpbY
2020-02-28T20:11:18 < jpa-> tcth: are you sick yet?
2020-02-28T20:12:15 < zyp> I don't know what sort of performance you'd get, but I'd guess the USB bus would be the bottleneck
2020-02-28T20:12:31 < tcth> jpa-, not yet
2020-02-28T20:12:43 < jpa-> with 8-bit SRAM the SRAM bus might be bottleneck, but with 16-bit SRAM it should be fast enough
2020-02-28T20:12:48 < tcth> just ate a deep frozen pizza for good measures
2020-02-28T20:12:55 < jpa-> of course the manuals have the timings so you can calculate it
2020-02-28T20:12:59 < kakimir> jpa-: how about buffering
2020-02-28T20:13:22 < jpa-> buffering what?
2020-02-28T20:13:38 < zyp> the usb fifos would provide a buffer
2020-02-28T20:13:58 < kakimir> sorry jpa. *zyp
2020-02-28T20:14:09 < kakimir> zyp: how big endpoint buffers?
2020-02-28T20:14:32 < zyp> configurable, IIRC you've got 4k total to work with
2020-02-28T20:14:45 < zyp> you need at least 512B per endpoint, since that's minimum packet size
2020-02-28T20:14:52 < zyp> or, actually
2020-02-28T20:15:00 < jpa-> why would buffer size even matter if it is just going to sram anyway?
2020-02-28T20:15:01 < kakimir> 64
2020-02-28T20:15:18 < kakimir> sram is shared
2020-02-28T20:15:28 < zyp> when you're using DMA I think the usb core can actually start a transfer before the whole packet is in the fifo
2020-02-28T20:15:43 < zyp> kakimir, 64?
2020-02-28T20:16:05 < kakimir> in high-speed mode
2020-02-28T20:16:11 < zyp> USB FS has 64B MPS, USB HS has 512B MPS
2020-02-28T20:16:20 < kakimir> sorry FS
2020-02-28T20:16:36 < zyp> well, if you're talking about FS the entire discussion is moot
2020-02-28T20:16:48 < zyp> you could bitbang sram fast enough to saturate FS USB
2020-02-28T20:16:55 < nn7> is there a way I can use the STLINK utility to determine if my STM32 is in the bootloader or not?
2020-02-28T20:17:10 < zyp> nn7, check the address in the PC register
2020-02-28T20:17:19 < nn7> fffffffe
2020-02-28T20:17:21 < zyp> should be 0x1fxxxxxx IIRC
2020-02-28T20:17:24 < nn7> the chip has bever been programmed
2020-02-28T20:17:30 < zyp> fffffffe is lockup
2020-02-28T20:17:31 < jpa-> ffffffffe is double-fault or something
2020-02-28T20:17:38 < jpa-> typical for unprogrammed chips
2020-02-28T20:17:47 < Thorn> double fault lockup
2020-02-28T20:18:00 < nn7> but it would be different if in the bootloader?
2020-02-28T20:18:06 < zyp> nn7, you have boot0 high, right? how about boot1?
2020-02-28T20:18:37 < zyp> there's three boot modes; flash, rom bootloader and ram
2020-02-28T20:18:57 < zyp> flash is boot0 low, the other two are boot0 high and selected with boot1
2020-02-28T20:19:02 < zyp> don't remember which is which
2020-02-28T20:19:11 < nn7> "boot1"?
2020-02-28T20:19:19 < zyp> selecting ram boot with boot1 would probably also put you in lockup
2020-02-28T20:19:31 < zyp> yeah, boot1 is a side function of one of the normal gpios
2020-02-28T20:19:34 < zyp> check the datasheet
2020-02-28T20:19:45 < nn7> ahh... pin 28
2020-02-28T20:20:08 < jpa-> i always wondered why someone would want to select ram boot with a pin
2020-02-28T20:20:15 < nn7> it's floating
2020-02-28T20:20:31 < zyp> figure out if you want it high or low, then add a pullup or pulldown
2020-02-28T20:20:50 < zyp> jpa-, yeah, it's pretty dumb
2020-02-28T20:22:03 < kakimir> usb-dma uses shared bus to transfer to FSMC?
2020-02-28T20:22:27 < jpa-> bus matrix, there is no shared bus in most of STM32's
2020-02-28T20:22:40 < kakimir> oh
2020-02-28T20:22:42 < zyp> yeah, I'd expect it to have it's own master port on the crossbar
2020-02-28T20:22:47 < nn7> AH HA! PC 0x1fff4252
2020-02-28T20:23:03 < zyp> that sounds like bootloader
2020-02-28T20:23:10 < nn7> That might explain why it seemed to work once and only once
2020-02-28T20:23:16 < zyp> yeah
2020-02-28T20:23:21 < jpa-> though on some devices such as STM32H7, the transfer would go through D2->D1 shared inter-domain bus
2020-02-28T20:24:01 < kakimir> but f4 uses bus matrix?
2020-02-28T20:24:11 < jpa-> but considering you only need one 4-byte transfer every 20 bus cycles, not much of load
2020-02-28T20:24:41 < jpa-> yeah, f4 has only one domain
2020-02-28T20:24:52 < Thorn> T - 2 h. https://www.youtube.com/watch?v=2Wzagx8kC7s
2020-02-28T20:25:48 < jpa-> SRAM on FSMC on STM32 is somewhat slow though, IIRC it takes a minimum of 6 cycles per write
2020-02-28T20:26:47 < nn7> thank you everyone for your help!!
2020-02-28T20:28:50 < jpa-> FMC is faster in that it has the write buffer so it will execute the writes back-to-back
2020-02-28T20:30:14 < jadew> BrainDamage, the two new ncov patients in Romania are also from Italy, but one of them didn't come from the quarantine zone

2020-02-28T20:31:12 < kakimir> so which chip to get jpa-?

2020-02-28T20:33:11 < zyp> jpa-, even in sram mode?
2020-02-28T20:33:41 < jpa-> kakimir: STM32F427 should have FMC i think
2020-02-28T20:33:57 < zyp> yes
2020-02-28T20:34:06 < zyp> FMC came with f42x line
2020-02-28T20:34:11 < zyp> and I believe f7 also got it
2020-02-28T20:34:23 < jpa-> zyp: yeah - difference being that with FSMC you first wait for the external transfer to complete and only then it finishes the internal AHB transfer and the next transfer can start
2020-02-28T20:35:39 < zyp> interesting
2020-02-28T20:36:10 < zyp> f42x and f40x are pin compatible, so there's a simple upgrade path there
2020-02-28T20:36:18 < jpa-> at least that is how it felt like it works - it's not very clear in docs how the AHB transfers are timed in relation with the external transfers, but there is no mention of any kind of buffer either
2020-02-28T20:37:17 < jpa-> yeah, and FMC control registers are also mostly compatible with FSMC registers
2020-02-28T20:40:43 < zyp> jpa-, you know some fpga stuff, right? what's a reasonable way to sync to an oversampled self-clocked signal? (FS USB, oversampled 4x)
2020-02-28T20:42:21 < jpa-> the phy from opencores i used did it this way:  https://github.com/PetteriAimonen/dso-quad-usb-analyzer/blob/master/fpga/usb_rx_phy.vhdl#L205
2020-02-28T20:42:55 < jpa-> but basically i'd just look for a change in the signal, and if it is too early or too late, skip clock cycles in your clock enable divider
2020-02-28T20:43:35 < kakimir> how much there is FMC buffer? 
2020-02-28T20:43:59 < jpa-> what does page 1600 of RM0090 say?

2020-02-28T20:47:09 < jpa-> zyp: also if you are reading the USB-FS signals as two single-ended signals, there is the trouble that sometimes one of them can change state 1 bit before the other - i used a hack like this to avoid trouble  https://github.com/PetteriAimonen/dso-quad-usb-analyzer/blob/master/fpga/edge_matcher.vhdl
2020-02-28T20:47:23 < kakimir> can FMC do direct transfers from one sram to another sram?
2020-02-28T20:47:48 < jpa-> kakimir: what's direct? DMA controllers can read from FMC and then write to FMC
2020-02-28T20:48:06 < kakimir> so that data never enters the system
2020-02-28T20:48:10 < kakimir> it's just clocked
2020-02-28T20:48:11 < zyp> jpa-, I've considered that possibility to, I figure a simple solution is to just require a signal to be stable for at least two 48MHz-cycles
2020-02-28T20:48:27 < jpa-> kakimir: no, that's not what it does; just bitbang the signals if that's what you are aiming for
2020-02-28T20:48:57 < zyp> lik:, if(state == prev_state) out_state = state; prev_state = state;
2020-02-28T20:49:07 < jpa-> zyp: you mean both signals (D+/D-) to be stable?
2020-02-28T20:49:13 < zyp> yes
2020-02-28T20:49:15 < jpa-> yeah
2020-02-28T20:49:35 < zyp> would delay everything one cycle, but I figure that doesn't matter

2020-02-28T21:32:22 < antto> the F?
2020-02-28T21:32:32 < zyp> yes, DoF is decided by aperture
2020-02-28T21:32:37 < antto> i know
2020-02-28T21:32:57 < antto> the beercan goes down to F/4 (and it's fixed across the zoom)
2020-02-28T21:32:58 < PaulFertser> :) it's artistic and all but not highly informative y'know
2020-02-28T21:33:11 < zyp> antto, that's up, not down
2020-02-28T21:33:22 < antto> i didn't *want* bokeh on this, i was just too lazy to put my F/1.7 lens
2020-02-28T21:33:30 < zyp> remember, it's a fraction
2020-02-28T21:33:41 < zyp> try f/16
2020-02-28T21:33:57 < PaulFertser> antto: it's not about bokeh, it's about that most of your board is defocused and you're supposedly showing the board
2020-02-28T21:34:07 < antto> no
2020-02-28T21:34:12 < zyp> (also, f/1.7 would give you more bokeh)
2020-02-28T21:34:15 < PaulFertser> antto: so if you closed the aperture we'd see more
2020-02-28T21:34:21 < antto> the interesting bits were in focus (green led, programmer)
2020-02-28T21:34:50 < PaulFertser> Green led already out I'd say
2020-02-28T21:35:14 < zyp> yeah
2020-02-28T21:35:33 < antto> yes, i was doing the shot hand-held, with poor light, so i opened it up to max, and went for that distant angle to get reflections from the monitor, i got to 1/20 shutter speed which is acceptable for handheld
2020-02-28T21:37:50 < antto> if i wanted to show the actual stuff on the board i'd make a better pic, like this:
2020-02-28T21:37:52 < antto> https://i.imgur.com/eZlyR8N.jpg
2020-02-28T21:38:03 < zyp> that's still pretty shit
2020-02-28T21:38:17 < antto> it's at a fancy angle for fancyness
2020-02-28T21:38:20 < PaulFertser> But we love you nevertheless antto 
2020-02-28T21:38:31 < Steffanx> What kind of camera is this antto?

2020-02-28T21:40:13 < zyp> you should use an appropriate pcb stand, like this: https://bin.jvnv.net/file/3jZMb.JPG

2020-02-28T21:41:18 < antto> but i bought two vintage minolta lenses
2020-02-28T21:41:22 < zyp> lens is more interesting than camera
2020-02-28T21:41:39 < zyp> most modern camera bodies can get nice results with a decent lens
2020-02-28T21:42:28 < zyp> hmm
2020-02-28T21:42:36 < zyp> my old pcb photos are kinda shitty too
2020-02-28T21:42:46 < zyp> https://bin.jvnv.net/file/r1ChW.JPG <- bad DoF
2020-02-28T21:42:54 < zyp> good lighting, but bad DoF
2020-02-28T21:42:59 < PaulFertser> I guess antto would be happy to make future PCB shots with a tilt shift :)
2020-02-28T21:43:05 < antto> i needed the camera to take photos and videos, and to have manual controlz
2020-02-28T21:43:32 < zyp> https://bin.jvnv.net/file/E08pl.JPG <- this one is pretty good, I'd say
2020-02-28T21:43:34 < antto> tho i don't actually use M mode, A mode is gud enough since i can lock the eggsposure
2020-02-28T21:43:55 < zyp> depends what you're shooting
2020-02-28T21:43:55 < antto> tilt shift is fancy
2020-02-28T21:44:11 < zyp> I use M or A depending on what
2020-02-28T21:44:39 < zyp> A for most stuff with natural light, M for flash photography
2020-02-28T21:45:01 < antto> ah, i don't liek flash
2020-02-28T21:45:10 < zyp> do you have a decent flash?
2020-02-28T21:45:19 < PaulFertser> zyp: are the through hole pads non-round for aesthetics or because of something else?
2020-02-28T21:45:21 < antto> nah, just the built-in one
2020-02-28T21:45:42 < zyp> antto, nobody likes that :)
2020-02-28T21:45:54 < antto> i shoot at $whatever conditions usually, if i need longer eggsposure i try to set it up to not shake around
2020-02-28T21:45:57 < zyp> PaulFertser, they are octagon pads with teardrops
2020-02-28T21:46:17 < PaulFertser> zyp: I'm not an EE, so asking why
2020-02-28T21:46:26 < zyp> no real reason
2020-02-28T21:46:38 < antto> for filming muh soldering, i used an additional E27 LED bulb hanging on a cable
2020-02-28T21:46:54 < zyp> IIRC this was the last design I did in eagle, played around with some script that added teardrops to all pads
2020-02-28T21:47:14 < PaulFertser> It looks kinda cool

2020-02-28T21:48:24 < jpa-> teardrops on vias adds a bit more margin for shitty drilling, but apparently that script only did pads
2020-02-28T21:48:41 < zyp> oh, I have power led pics too

2020-02-28T21:49:11 < PaulFertser> Talking about E27, I would expect a LED strip on alu bar to have much better reliability because of more favourable cooling conditions. But is it really true when comparing decent E27 bulbs (e.g. IKEA) with "regular LED strip" from eBay?
2020-02-28T21:49:48 < zyp> jpa-, I think I'd say the rework quality is higher than the photo quality :)
2020-02-28T21:50:22 < zyp> nice deadbugged qfn
2020-02-28T21:50:28 < jpa-> PaulFertser: decent E27 bulbs have worked better for me than similar EUR/watt priced mains powered led strip lamps
2020-02-28T21:50:49 < jpa-> the led strip lamps have had crappy power supplies that spew a lot of EMI and some have broken quite quickly
2020-02-28T21:51:10 < zyp> Ultrasauce, I present to you the tower of parallel capacitance: https://bin.jvnv.net/file/m0yyr.JPG
2020-02-28T21:51:40 < antto> zyp i guess you have a proper macro lens
2020-02-28T21:51:43 < PaulFertser> jpa-: I'm assuming one gets a power supply separately, so I'm considering only the LEDs.
2020-02-28T21:51:52 < Ultrasauce> https://youtu.be/cHWs3c3YNs4?t=36
2020-02-28T21:52:00 < zyp> antto, yes, the Canon 60mm
2020-02-28T21:52:33 < antto> well, i use an UV filter with a magnifying glass epoxy-glued onto it
2020-02-28T21:52:42 < antto> ;P~
2020-02-28T21:52:42 < zyp> haha
2020-02-28T21:52:55 < BrainDamage> PaulFertser: leds have crazy high MTBF, the point of failure is nearly always the psu
2020-02-28T21:53:10 < zyp> antto, it's my cheapest decent lens
2020-02-28T21:53:11 < PaulFertser> BrainDamage: unless they're constantly overheating
2020-02-28T21:53:23 < zyp> good macros are prime, so the construction isn't very complex
2020-02-28T21:53:26 < PaulFertser> BrainDamage: and that's what I'd expect in many E27 devices due to size constraints.
2020-02-28T21:53:39 < invzim> polarizing filters get rid of light source glare on PCB's yah?
2020-02-28T21:53:42 < Ultrasauce> its often the dropper cap that goes in those
2020-02-28T21:53:48 < antto> yeah, i make the "better" pics with my prime lens plus this ghetto macro filter

2020-02-28T21:54:14 < antto> but it's not like proper macro
2020-02-28T21:54:14 < zyp> antto, I mean, macros are cheap, you should get one :)
2020-02-28T21:54:26 < invzim> application is purely practical, I get reflections and crap with my microscope
2020-02-28T21:54:49 < zyp> hmm
2020-02-28T21:54:50 < BrainDamage> invzim: some, but not all
2020-02-28T21:54:52 < invzim> as I think the ring-light thingie is not designed for the distance I have
2020-02-28T21:55:05 < antto> nah, i tossed a lot of $$$ recently on this arm corteggz eggsperiment
2020-02-28T21:55:05 < jpa-> PaulFertser: well you don't get power supply separately for E27
2020-02-28T21:55:11 < zyp> apparently the one I've got is $350 now, thought it were cheaper
2020-02-28T21:55:12 < BrainDamage> works better the  more angled the light source is compared to the observer
2020-02-28T21:55:13 < antto> no new toys for me for a while
2020-02-28T21:55:25 < BrainDamage> so if your light ring is tight, you won't see much improvement
2020-02-28T21:55:26 < invzim> BrainDamage: roger
2020-02-28T21:55:33 < jpa-> PaulFertser: but yeah, if you get a separate decent supply for a led strip, it is probably better but also more expensive
2020-02-28T21:55:36 < Steffanx> Ask the bossman for a raise antto :P
2020-02-28T21:55:54 < PaulFertser> jpa-: well, and that's adding to the silliness of the concept, they have to pack decent PSU in pretty small and quite heated space.
2020-02-28T21:56:16 < jpa-> PaulFertser: yeah, and they're doing surprisingly good job at it at ridicuously low prices
2020-02-28T21:56:31 < antto> Steffanx it's not a gud moment now, when muh xmega firmware seems to be suffering from broken stack
2020-02-28T21:56:55 < antto> i'd rather need to inform $boss to buy an atmel-ice
2020-02-28T21:56:59 < PaulFertser> jpa-: indeed
2020-02-28T21:57:07 < zyp> huh, apparently I paid close to $400 for the macro lens, thought it were less
2020-02-28T21:57:16 < Steffanx> I blame your use of c++ antto
2020-02-28T21:57:28 < zyp> but still, it's cheap
2020-02-28T21:57:29 < antto> zyp my minolta prime iirc was 200euro
2020-02-28T21:57:32 < Steffanx> What you use instead antto?
2020-02-28T21:57:37 < Steffanx> atmel-ice is cheapish right?
2020-02-28T21:57:39 < Steffanx> 50$?

2020-02-28T22:00:06 < antto> old minoltas are cheap
2020-02-28T22:00:23 < zyp> my decent lenses are the 60mm macro, 17-55/2.8 and 70-200/2.8
2020-02-28T22:00:26 < invzim> my impression is that a lot of photography guys are like hifi-guys, i.e. finding increasingly subtle errors in increasingly expensive kit

2020-02-28T22:00:49 < zyp> yeah
2020-02-28T22:00:59 < antto> besides the kit lens, i got 50mm/F1.7 and the beercan
2020-02-28T22:01:21 < PaulFertser> Steffanx: xmega is not interesting, it's just pain for no gain these days.
2020-02-28T22:01:32 < zyp> my problem is that I'm mostly too fucking lazy to bring the camera anywhere when I got a smartphone in my pocket
2020-02-28T22:01:41 < antto> PaulFertser xmega is what atmegas should have been
2020-02-28T22:01:58 < Steffanx> i know PaulFertser.
2020-02-28T22:02:18 < PaulFertser> antto: most of that just doesn't matter since long, when the first cortex-m devices hit the market.
2020-02-28T22:02:34 < antto> xmega is easy to learn
2020-02-28T22:02:36 < PaulFertser> antto: and now if you plan to produce something on large scale you have stm8
2020-02-28T22:02:37 < zyp> recently I've been taking the camera off the shelf once a month to snap some monthly photos of the kid
2020-02-28T22:02:43 < Steffanx> the only thing that might be slightly interesting is the event system in combination with the "WEX" to make fancy wave forms/pwm stuff
2020-02-28T22:02:44 < BrainDamage> invzim: btw, polarized filters work due to https://en.wikipedia.org/wiki/Brewster%27s_angle
2020-02-28T22:03:00 < antto> PaulFertser does gcc support those stm8s?

2020-02-28T22:03:18 < PaulFertser> antto: and you get debugging for free with stlink.
2020-02-28T22:03:26 < antto> i have eggsperience with SDCC because of pic only
2020-02-28T22:03:32 < antto> and iirc it doesn't do C++
2020-02-28T22:03:37 < PaulFertser> With PIC it's more painful. Yes, no C++.
2020-02-28T22:03:41 < invzim> BrainDamage: yup, so not much use if you have direct overhead light on a pcb
2020-02-28T22:03:53 < zyp> I don't understand the appeal of stm8
2020-02-28T22:03:58 < PaulFertser> antto: does it matter, are you going to produce like 10k devices or so?
2020-02-28T22:04:12 < zyp> what does it do so much better than avr that it's worth putting up with sdcc for?
2020-02-28T22:04:14 < BrainDamage> invzim: yeah, what you could do instead is add a diffuser medium

2020-02-28T22:04:59 < BrainDamage> invzim: you could try cheap, just take a piece of paper and put it close to the ring
2020-02-28T22:05:10 < BrainDamage> it should improve things significantly
2020-02-28T22:05:37 < antto> xmega is easy to learn, easy to code (SFR structure is spread out nicely), and slightly cheaper than atmegas
2020-02-28T22:05:43 < invzim> I'll give it a go next time, I will prob need more lumen oomphfs
2020-02-28T22:05:49 < antto> and gcc
2020-02-28T22:05:51 < PaulFertser> zyp: and if you do not need super-cheap you can get cortex-m
2020-02-28T22:05:53 < BrainDamage> nah, use https://en.wikipedia.org/wiki/Wrapping_tissue
2020-02-28T22:05:57 < zyp> PaulFertser, yes
2020-02-28T22:05:59 < PaulFertser> atmega is not nearly super-cheap these days

2020-02-28T22:06:55 < Steffanx> Some attinys arent actually too expensive.
2020-02-28T22:06:55 < antto> xmegas pack moar stuff and are slightly cheaper
2020-02-28T22:07:09 < specing> the smaller stm32 are cheaper than equivalent atmegas and pack a bigger punch
2020-02-28T22:07:10 < Steffanx> it seems they got a bit cheaper since the microchip took over.
2020-02-28T22:07:24 < antto> specing you forgot the "easy to learn" maybe
2020-02-28T22:07:39 < PaulFertser> I wonder if this will work with sdcc https://github.com/JuliaComputing/llvm-cbe
2020-02-28T22:08:08 < PaulFertser> The project looks quite active
2020-02-28T22:08:18 < specing> antto: nah, the stm32 aren't that harder and the tooling is better
2020-02-28T22:08:44 < zyp> how's riscv silicon coming along? I figure they can be made pretty cheap except they won't have enough volume to make NRE costs negligible yet
2020-02-28T22:09:04 < antto> specing are you including IDEs and code generators into this?
2020-02-28T22:09:20 < specing> antto: ?
2020-02-28T22:09:24 < specing> Sure?
2020-02-28T22:09:27 < Steffanx> does antto actually like atmel start?

2020-02-28T22:09:41 < antto> cuz i don't
2020-02-28T22:09:48 < specing> zyp: its being made in the millions
2020-02-28T22:10:04 < PaulFertser> specing: judging from the perspective of someone who doesn't use cubemx and other code generators etc.
2020-02-28T22:10:38 < specing> PaulFertser: I use GPS and write my own code for everything, just like I did back then on AVR
2020-02-28T22:10:48 < Steffanx> Ada on AVR?
2020-02-28T22:11:07 < specing> The only part that is "harder" is that you have to turn on periph, clocks
2020-02-28T22:11:10 < specing> thats it
2020-02-28T22:11:36 < antto> specing for xmega i RTFM'ed the datasheet and wrote my own "periph drivers" i guess, and when i was stuck i've looked into application notes which have eggzample code (which has been ASF) to see how they do it or to steal chunks from it
2020-02-28T22:11:37 < Steffanx> and configure some clock
2020-02-28T22:11:37 < specing> Steffanx: It's possible, but the toolchain is not that actively supported
2020-02-28T22:11:43 < Steffanx> not forget you have flash wait states
2020-02-28T22:11:57 < Steffanx> All kinds of stuff you dont need with AVR
2020-02-28T22:11:57 < zyp> Steffanx, nah, you can just stay on HSI
2020-02-28T22:11:58 < antto> specing if i was gonna do the same on arm cortex - arm is much harder
2020-02-28T22:12:08 < specing> antto: that's what I did on mega and that's what I do on stm32
2020-02-28T22:12:19 < antto> wait, Ada?
2020-02-28T22:12:23 < PaulFertser> specing: just compare the size of the datasheet + reference manual. Clearly much more features make it harder just because you have more choices, more control over things.
2020-02-28T22:12:32 < specing> Steffanx: I haven't had to think about any wait states so far
2020-02-28T22:12:35 < zyp> PaulFertser, no, it doesn't
2020-02-28T22:12:52 < zyp> PaulFertser, you're making an unfair comparison
2020-02-28T22:12:53 < specing> PaulFertser: that actually makes it easier, as you have many ways of going about a problem
2020-02-28T22:13:04 < specing> antto: yes, Ada
2020-02-28T22:13:22 < zyp> PaulFertser, yes, it is harder to make use of every feature that stm32 offers, than what avr offers
2020-02-28T22:13:55 < Steffanx>  specing: You always have to think about it, when it has configuration bits for it. At least read about it to see if you need to change some bits
2020-02-28T22:14:03 < antto> xmega A manual (that describes peripherals, not any specific chip from the family) is iirc 500 pages
2020-02-28T22:14:11 < PaulFertser> zyp: but even when you need the same subset of features you still have to read more and to understand more to make use of them on stm32 I'd say.
2020-02-28T22:14:12 < Steffanx> except when you run of the defaults ofcourse
2020-02-28T22:14:15 < zyp> PaulFertser, but if there's even a point to make the comparison, the relevant project can only use a subset of those that's available on both
2020-02-28T22:14:45 < specing> Steffanx: the hardest problem I had so far was that I made an init routine and forgot to call it, then wondered why it doesen't work
2020-02-28T22:15:08 < specing> Steffanx: the defaults are quite sane
2020-02-28T22:15:18 < antto> basically i agree with what PaulFertser says.. for a guy who knows the language but has no eggsperience with MCUs and sh*t, and who doesn't like vendor IDEs, avr is easier to learn
2020-02-28T22:15:19 < Steffanx> specing: So no PLL stuff for you yet?
2020-02-28T22:15:23 < antto> if you only wanna blink a LED
2020-02-28T22:15:26 < specing> Steffanx: PLL is done by the runtime
2020-02-28T22:15:46 < Steffanx> specing: the runtime?
2020-02-28T22:15:49 < specing> when my code runs, the cpu is already at 48MHz and APB&AHB are already clocked
2020-02-28T22:15:58 < Steffanx> Ada?
2020-02-28T22:16:05 < specing> Steffanx: yes, Ada usually has a runtime wherever it runs

2020-02-28T22:17:10 < specing> Ada is cheating compared to C, indeed :P
2020-02-28T22:17:15 < specing> (or C++)
2020-02-28T22:17:24 < zyp> antto, apart from having to turn on the GPIO clock, blinking a led is the same; write one register to set the pin as output, write another register to set the value of the pin, repeat
2020-02-28T22:17:27 < specing> when the compiler fishes out 95% of the errors out for you
2020-02-28T22:17:42 < specing> that would make it into the final binary with C++
2020-02-28T22:17:52 < antto> zyp yes, i got a blinking LED now, but i cheated
2020-02-28T22:18:04 < BrainDamage> the most unappealing part of ada is the ada foundation
2020-02-28T22:18:20 < antto> i mean, even figuring out the pinout of your peripheral sh*t can be x_x
2020-02-28T22:18:29 < BrainDamage> there's this weird mix of open source and commercial
2020-02-28T22:18:31 < Steffanx> specing: no using some tool that does it all for you and then comparing that to AVR to say STM32 is easier.
2020-02-28T22:18:34 < Steffanx> that is cheating.
2020-02-28T22:18:38 < antto> so many "gotchas" in the datasheet
2020-02-28T22:18:42 < Steffanx> or an unfair comparison.
2020-02-28T22:18:44 < Steffanx> whatever you want to call it
2020-02-28T22:19:19 < antto> datasheet on this cortex M4F iirc is 2000 pages

2020-02-28T22:19:44 < Steffanx> American Dental Association
2020-02-28T22:20:07 < specing> Steffanx: Ada on AVR also has such a runtime
2020-02-28T22:20:14 < antto> i lied, 2129 pages
2020-02-28T22:20:15 < specing> its not cheating, its a fair comparison
2020-02-28T22:20:27 < Steffanx> specing: Did you use ADA on AVR?
2020-02-28T22:20:30 < specing> no
2020-02-28T22:20:48 < Steffanx> Nah Arduino is much easier then.
2020-02-28T22:20:49 < specing> I used AVRs before I learned that Ada existed
2020-02-28T22:21:00 < specing> since then it has been 100% Ada 
2020-02-28T22:21:16 < Steffanx> I did SPI.transfer(x,y) and it just works
2020-02-28T22:21:20 < antto> Steffanx when i learnt about Ada, i wanted to try it on avr, but i couldn't figure it out within 20 minutes so i said "meh, fugg it"

2020-02-28T22:29:13 < specing> there hasn't been a GNAT community release for AVR since 2012 or so
2020-02-28T22:29:16 < mawk> you don't like sketching antto ???
2020-02-28T22:29:20 < PaulFertser> I attached it to my laptop so when my friend came with an AP with certain SSID enabled on his smartphone my laptop saw it in the scan and turned the servo and he got a packet (with 3d-printed shit) dropped from my balcony while I was at work.

2020-02-28T23:40:50 < Thorn> what is this https://www.aliexpress.com/item/32839125762.html
2020-02-28T23:41:15 < PaulFertser> jadew: btw, are you getting flu vaccine yearly?
2020-02-28T23:41:25 < jadew> Thorn, looks like fake stuff
2020-02-28T23:41:33 < jadew> PaulFertser, only got it a couple of times so far
2020-02-28T23:41:45 < PaulFertser> jadew: why?
2020-02-28T23:42:03 < jadew> fitness
2020-02-28T23:42:36 < PaulFertser> Does vaccine interfere with your fitness?
2020-02-28T23:42:42 < jadew> I avoid taking drugs as much as possible, to allow my body to learn how to fight whatever it's fighting 
2020-02-28T23:43:16 < jadew> I meant immune system fitness
2020-02-28T23:43:23 < PaulFertser> But vaccine do exactly that, they allow your body to learn to fight flu.
2020-02-28T23:43:32 < jadew> not really
2020-02-28T23:44:10 < jadew> it doesn't have to deal with the effects
2020-02-28T23:44:46 < PaulFertser> Yes, it teaches to fight virus so when you actually get it you are mostly free from effects because it's killed fast.
2020-02-28T23:44:52 < PaulFertser> Seems to be a good way to handle it.
2020-02-28T23:45:07 < jadew> I know, but it doesn't go through the usual fever cycle and all that
2020-02-28T23:46:06 < PaulFertser> So you prefer to actually go through flu illness?
2020-02-28T23:46:09 < jadew> that said, I'm sporting a runny nose right now
2020-02-28T23:46:15 < jadew> PaulFertser, yeah

2020-02-28T23:48:49 < PaulFertser> jadew: I'm surprised you consider it beneficial for your health, I do not think I remember hearing anyone advocating something like that.
2020-02-28T23:50:43 < jadew> don't know... seems reasonable to me
2020-02-28T23:50:59 < jadew> why take drugs if you can handle it yourself?
2020-02-28T23:51:11 < PaulFertser> vaccines are not drugs
2020-02-28T23:51:23 < jadew> well, I'm not an anti-vaxer
2020-02-28T23:51:50 < jadew> but at my age, flu is not that dangerous
2020-02-28T23:52:35 < Steffanx> Except when its CORONAAAAA
2020-02-28T23:52:39 < jadew> yeah
2020-02-28T23:52:44 < jadew> I'd get a vaccine for that
2020-02-28T23:52:46 < Steffanx> Hah.
2020-02-28T23:52:47 < qyx> common flu is ok
2020-02-28T23:53:01 < qyx> actually I never had >38C for the past ~15y
2020-02-28T23:53:02 < Steffanx> Man flu is the worst.
2020-02-28T23:53:04 < PaulFertser> To me it sounds like you say why protect your hands from cuts with clothing when you can just let the body heal the skin each time you get scarred.
2020-02-28T23:53:26 < jadew> PaulFertser, not really
2020-02-28T23:53:42 < jadew> I mean... if you rarely get cut, sure
2020-02-28T23:53:45 < jadew> don't protect yourself
2020-02-28T23:53:53 < jadew> it's the same with the flu
2020-02-28T23:56:07 < Laurenceb> saw the biohazard suit guys when i was out earlier
2020-02-28T23:56:44 < PaulFertser> jadew: my point is that it's usually assumed that getting vaccinated against flu has benefits and no downsides while going through fever is actually risky and not beneficial in any way.
2020-02-28T23:56:59 < jadew> PaulFertser, yeah, I disagree with that
2020-02-28T23:57:29 < jadew> fever is part of the immune response and it triggers other responses in the body
2020-02-28T23:57:49 < Laurenceb> >triggered
2020-02-28T23:57:58 < jadew> it's not really ok to inhibit it
2020-02-28T23:58:14 < jadew> and I think having those systems kicked into action from time to time is not that bad of a thing either
2020-02-28T23:59:07 < qyx> yeah it is not like dying at 41°C for 3 days
2020-02-28T23:59:13 < jadew> if you just take flu shots and never truly fight a flu virus, when you finally get infected with a real one, your body might try to deal with it like it did with the duds
2020-02-28T23:59:15 < Thorn> >triggers other responses in the body -- yeah such as a cytokine storm 
2020-02-28T23:59:16 < jadew> in lazy mode
2020-02-28T23:59:21 < qyx> but under 38°C it is not recommended to take some serious action
--- Day changed Sat Feb 29 2020
2020-02-29T00:00:20 < PaulFertser> jadew: that idea of yours, is it supported by some statistics, probably pubmed articles?
2020-02-29T00:01:28 < jadew> PaulFertser, I don't know, but given how we tend to adapt to our environment in other aspects, I don't see why it wouldn't happen in this one too
2020-02-29T00:02:48 < jadew> PaulFertser, doctors here are pumping you full of meds from the get go
2020-02-29T00:03:06 < jadew> the first thing they attack is the fever
2020-02-29T00:03:18 < BrainDamage> you're diving deeper and deeper in pseudoscience along your anxiety
2020-02-29T00:03:22 < Thorn> ##antivaxx32
2020-02-29T00:03:49 < jadew> I always assumed fever was good because I learned in biology that the reason we get a fever is because many viruses and bacteria that are evolved to live in humans, can't live if the temperature changes with even 2 degrees
2020-02-29T00:04:03 < BrainDamage> that is wrong
2020-02-29T00:04:10 < PaulFertser> jadew: aren't hey following the established protocols from evidence-based medicine?
2020-02-29T00:04:35 < BrainDamage> with increased temperature the replication rate of T cells increases exponentially, faster than bacterias
2020-02-29T00:04:42 < jadew> PaulFertser, I don't know, I just think stopping a fever from the get go is wrong
2020-02-29T00:04:50 < BrainDamage> and bacterias also do benefit from increased temp
2020-02-29T00:04:59 < BrainDamage> but not as much as your immune system
2020-02-29T00:05:02 < jadew> BrainDamage, ah, so it's just to help the immune system?
2020-02-29T00:05:14 < BrainDamage> it also can go overboard
2020-02-29T00:05:20 < jadew> got it, perhaps that info was wrong, but it's what has stuck with me
2020-02-29T00:05:54 < BrainDamage> your immune system is essentially another autonomous entity that lives with you and makes its own decisions
2020-02-29T00:06:17 < BrainDamage> it can decide that a part of you is a enemy and you get autoimmune diseases
2020-02-29T00:06:20 < PaulFertser> BrainDamage: do you think it's the standard way to treat fever, to stop it right away? I personally just drink water and wait, and if it's too unbearable then I take paracetamol.
2020-02-29T00:06:44 < BrainDamage> at least not here
2020-02-29T00:06:47 < jadew> PaulFertser, I do the same
2020-02-29T00:06:53 < jadew> here they try to stop it
2020-02-29T00:07:37 < BrainDamage> and don't think for a second that your immune system also always knows what's best for you
2020-02-29T00:07:45 < PaulFertser> jadew: idk, in russia many general practice doctors are just incapable. Some even "prescribe" homeopathy.
2020-02-29T00:08:01 < PaulFertser> jadew: is it the same in your country?

2020-02-29T00:08:10 < Mangy_Dog> woohooo
2020-02-29T00:08:15 < Cracki> here, have some shit beetle, diluted by 10^300
2020-02-29T00:08:17 < BrainDamage> inflammation and histamines are another mechanism to increase blood perfusion 
2020-02-29T00:08:19 < jadew> PaulFertser, it is, yes
2020-02-29T00:08:20 < Mangy_Dog> my stm32f103 + ft810 dev kit works
2020-02-29T00:08:35 < BrainDamage> at the same time, they swelling can leave you paralyzed
2020-02-29T00:08:37 < BrainDamage> or dead
2020-02-29T00:09:15 < aandrew> Interesting. STM32 safety library
2020-02-29T00:09:24 < PaulFertser> jadew: that's too bad :/ But that also means that it doesn't matter what they advice. Because you know that false can imply both false and true.
2020-02-29T00:09:58 < jadew> BrainDamage, yeah, I know
2020-02-29T00:10:20 < BrainDamage> a light fever is ok to leave as is
2020-02-29T00:10:33 < BrainDamage> as fever increases, the chances of damage from the fever exceed the benefit
2020-02-29T00:11:07 < jadew> I think 40 °C is where I draw the line
2020-02-29T00:11:10 < jadew> 39 is fine
2020-02-29T00:11:11 < BrainDamage> so it's perfectly ok to take antypirectics ( fever suppressors )
2020-02-29T00:11:15 < BrainDamage> 40 is ER worthy
2020-02-29T00:11:21 < jadew> nah
2020-02-29T00:11:30 < aandrew> I also thought the raised temp was to make it harder for bacteria/viruses to proliferate because it’s outside their optimal temp
2020-02-29T00:11:37 < jadew> you can do even 41-42 for a couple of hours and not die
2020-02-29T00:11:41 < aandrew> Porque no los dos?
2020-02-29T00:12:07 < aandrew> Here we also tend to let a fever persist until “too much time” has passed without it breaking, or it rises into the danger zone
2020-02-29T00:12:32 < BrainDamage> here ER will take you with >40, it's already damage inducing 
2020-02-29T00:12:46 < jadew> BrainDamage, only if it persists
2020-02-29T00:12:51 < BrainDamage> just because you're not in danger of immediate death it doesn't mean you won't have consequences
2020-02-29T00:12:57 < jadew> if you get 40 for 10 minutes and it drops, you're fine
2020-02-29T00:13:26 < jadew> I did have problems from my last fever last year
2020-02-29T00:13:34 < BrainDamage> that's pretty much obvious
2020-02-29T00:13:45 < BrainDamage> but you don't get 10 min temp fluctuations from infections
2020-02-29T00:13:50 < jadew> joint aches - but they went away after a couple of weeks
2020-02-29T00:14:11 < jadew> BrainDamage, yeah, but you can bring it down in 10-15 minutes if it goes over the limit
2020-02-29T00:14:29 < jadew> so it's not a reason to panic
2020-02-29T00:14:51 < BrainDamage> ok, so a potentially life threatening condition is not a reason to panic
2020-02-29T00:15:07 < BrainDamage> while a virus with 0.2% mortality rate for your age bin is
2020-02-29T00:15:15 < jadew> it's not life threatening until you have it for ~5 hours but I'm not sure what temperature it was
2020-02-29T00:15:18 < jadew> 41 or 42
2020-02-29T00:15:21 < jadew> not 40
2020-02-29T00:15:53 < jadew> also, there are really quick ways of dealing with super high fever
2020-02-29T00:16:07 < jadew> cold shower for example
2020-02-29T00:16:10 < aandrew> cold bath is probably the most accessible
2020-02-29T00:16:13 < jadew> yeah
2020-02-29T00:16:28 < jadew> that's enough time for the ibuprofen or whatever to kick in
2020-02-29T00:16:35 < aandrew> anyone here used the STM32 safety library? new contract has me as their safety consultant
2020-02-29T00:16:48 < Cracki> "the safety library"?
2020-02-29T00:17:12 < aandrew> yeah. it’s a lib that basically verifies the peripherals are set up the way you think they are. for IEC 61508
2020-02-29T00:17:20 < Cracki> is that a fancy word for watchdog and stuff?
2020-02-29T00:17:22 < Cracki> ah
2020-02-29T00:17:28 < Cracki> curious!
2020-02-29T00:17:39 < aandrew> https://www.st.com/en/embedded-software/x-cube-stl.html
2020-02-29T00:17:47 < aandrew> no, not the watchdog
2020-02-29T00:17:56 < aandrew> that’s something else again
2020-02-29T00:19:53 < jadew> BrainDamage, https://www.healthlinkbc.ca/health-topics/fevr4
2020-02-29T00:20:07 < PaulFertser> jadew: but you do not rely on "common sense" when thinking about quantum mechanics, so why do you think your judgements about health are better than the statistically sound results from the evidence-based medicine?
2020-02-29T00:20:14 < jadew> "Most healthy children and adults can tolerate a fever as high as 39.4°C (103°F) to 40°C (104°F) for short periods of time without problems."
2020-02-29T00:20:40 < BrainDamage> as you can see your own source cites 40 as the treshold
2020-02-29T00:20:53 < jadew> PaulFertser, because I don't think they've taken everything into account
2020-02-29T00:21:00 < jadew> like long term effects
2020-02-29T00:21:18 < jadew> BrainDamage, yeah, that's my threshold too
2020-02-29T00:21:20 < aandrew> I may also be able to work on the qemu stm32f4 core for this contract
2020-02-29T00:21:33 < aandrew> basically for being able to virtually test the firmware and inject faults
2020-02-29T00:21:42 < Thorn> moneyed western safety consultants
2020-02-29T00:21:45 < Cracki> evidence-based means they show you how they came to their conclusion, so you can verify it. it doesn't mean "believe our conclusion"
2020-02-29T00:22:04 < Cracki> so jadew is wanting to write a grant proposal
2020-02-29T00:22:04 < BrainDamage> aandrew: are you able to emulate peripherials too or just the core?
2020-02-29T00:22:17 < PaulFertser> jadew: I'd expect to find plenty of research regarding long-term effects on pubmed... 
2020-02-29T00:22:20 < aandrew> BrainDamage: it has some peripheral support as well
2020-02-29T00:22:37 < aandrew> BrainDamage: for this I would need eth and timers, not much else
2020-02-29T00:23:03 < jadew> PaulFertser, on vaccines or on fever?
2020-02-29T00:23:16 < PaulFertser> jadew: on all common topics
2020-02-29T00:25:02 < jadew> probably if you searched if it's ok to skip a flu vaccine from time to time, you'd find a lot of pro-vaxer stuff, because of the anti-vaxer movement, so that can all be discarded because the motivations are coming from the wrong place

2020-02-29T00:26:24 < jadew> about the fever - it's worth looking into it, sure, but I've already read a lot on fever because at first, every time my kid got sick, it was a mini crysis, so I've already read a lot on it
2020-02-29T00:26:26 < BrainDamage> if only there were medical journals with peer review from actual scientists
2020-02-29T00:26:35 < jadew> the medical establishment seems to think what I just quoted above
2020-02-29T00:27:02 < PaulFertser> jadew: EBM is about statistics with results reproduced by different labs, so it's not that dependent on the motivations and movement. At least it's not supposed to be, being constructed that way.
2020-02-29T00:28:21 < jadew> I'd still be skeptical if they clearly found that it's better or the same to get vaccinated than to get natural immunity via infection
2020-02-29T00:28:56 < jadew> it's easy to play with the results, and nobody wants to give fuel to anti-vaxers
2020-02-29T00:29:08 < Cracki> so... I have a motor with 2.3mm shaft, and I wanna get an encoder wheel on that. the cheapest I can find on aliex has 5mm center hole. 3d-print some "corks" with 2.3mm hole so I can glue the metal disk in between those on the shaft? alignment will obviously need some fiddling
2020-02-29T00:29:10 < aandrew> I don’t get the flu vaccine. it seems more of a gamble as to whether the formulation is actually useful year to year
2020-02-29T00:29:11 < Cracki> better ideas?
2020-02-29T00:29:16 < Cracki> (one-off, or two-off)
2020-02-29T00:29:23 < jadew> aandrew, agree
2020-02-29T00:30:08 < aandrew> Cracki: I’ve found similar shims to allow you to make a shaft bigger (or the gear hole to be smaller) — mixed results
2020-02-29T00:30:12 < PaulFertser> aandrew: but if chances to win are that high, and you do not lose much by not winning, that sounds still worthy.
2020-02-29T00:30:15 < Cracki> jadew, I think your argument is one level below eugenics :D I see how you worry that the immune system gets cheatsheets and doesn't learn to learn
2020-02-29T00:30:51 < Cracki> the encoder disk is thin metal, I'm not sure I can shim that. the motor I have that has such a wheel... also has plastic "corks" and I think they're glued on and the disk between both
2020-02-29T00:31:18 < BrainDamage> jadew: pretty sure it's better to get vaccinated, for one you won't risk your life, and for second, sickness can leave permanent damage
2020-02-29T00:31:24 < Cracki> a 3d printer isn't gonna be exact, their parts tho might take care of alignment already
2020-02-29T00:31:31 < aandrew> there’s a specific term for that shaft “cork” or shim, I cannot remember the name of it though
2020-02-29T00:31:37 < BrainDamage> while vaccines are super tested to be safe in 99.9% of the cases
2020-02-29T00:31:49 < jadew> BrainDamage, assuming you will have a vaccine for everything that you might encounter
2020-02-29T00:32:07 < BrainDamage> you're always exposed to a hostile environment
2020-02-29T00:32:26 < Cracki> as for vaccination or waiting to become sick: the herd immunity argument kinda solves that. vaccinate as many strong and healthy ones as you can, skip the vulnerable ones, so *they* don't get sick

2020-02-29T00:33:31 < Cracki> what I call cork approaches the disk axially, doesn't "wedge" it against the shaft radially
2020-02-29T00:34:04 < Cracki> a population that's used to "immune system cheat sheets" may develop weak immune systems
2020-02-29T00:34:10 < Cracki> same as with crooked teeth and braces
2020-02-29T00:34:11 < jadew> BrainDamage, I'm not saying vaccines are not tested, but I think it's just not the same, so I guess the question that needs to be answered is how much better (if at all) it is to take the flu and get better by yourself, than to get a vaccine
2020-02-29T00:34:19 < aandrew> Cracki: by what logic?
2020-02-29T00:34:23 < Cracki> braces hide the bad genes, allow them to propagate

2020-02-29T00:34:47 < aandrew> Cracki: immune system cheat sheets don’t shortcut anything, they provide weakened copies of the contagion for your body to safely learn from
2020-02-29T00:35:08 < aandrew> lol crooked teeth is somehow genetically poorer
2020-02-29T00:35:26 < Cracki> it is, isn't it
2020-02-29T00:35:48 < jadew> imo, the common flu is a great practice virus
2020-02-29T00:36:20 < BrainDamage> jadew: now you're formulating conclusions based off an untested hypothesis
2020-02-29T00:36:20 < aandrew> jadew: for flus like it, sre
2020-02-29T00:36:21 < aandrew> sure
2020-02-29T00:36:34 < Steffanx> You guys make it sound like getting a vaccine is very common. Here dutchland its not at all. Unless you have some condition that might affect your immune system or you're just old.
2020-02-29T00:36:38 < Cracki> if it's some serious shit, I'd get vaccinated tbh. if it's the common flu, I'd rather take the week at home shaking and aching than let someone jab a needle in my arm
2020-02-29T00:37:01 < Steffanx> I mean. Some yearly flu vaccine.
2020-02-29T00:37:11 < aandrew> Steffanx: here (Canada) it’s not only common, it’s required for many diseases (measles, mumps, rubella, tetanus, etc.)
2020-02-29T00:37:14 < BrainDamage> here vaccines for the flu are optional and offered for free if you're in a risk cathegory
2020-02-29T00:37:16 < jadew> BrainDamage, until I have my answer for that question, I have to choose one path
2020-02-29T00:37:36 < jadew> same here
2020-02-29T00:37:38 < BrainDamage> jadew: you have an alternative path, inform yourself rather than go off based your guess
2020-02-29T00:37:39 < Steffanx> Yeah that indeed, BrainDamage  
2020-02-29T00:37:47 < AndrevS> Here it's like a flu shot is for the elderly. Young people usually don't get flu shots 
2020-02-29T00:38:07 < jadew> same here
2020-02-29T00:38:08 < Cracki> measles, mumps, tetanus, ... vaccination against that is common here too. kids get it, not sure if adults still need it... or a booster every decade
2020-02-29T00:38:21 < Steffanx> Your here is the same as my here,  AndrevS  :P
2020-02-29T00:38:23 < BrainDamage> for serious class of diseases, vaccines are considered mandatory but wasn't enforce until lately
2020-02-29T00:38:59 < BrainDamage> as vaccination rates dropped, the mandatory become enforced by requiring mandatory vaccinations to be enrolled in public school
2020-02-29T00:39:02 < Cracki> hmmm I think I'll have to 3d-print some shit again
2020-02-29T00:39:17 < jadew> BrainDamage, is the flu among them?
2020-02-29T00:39:19 < BrainDamage> which is perfectly reasonable

2020-02-29T00:39:26 < BrainDamage> no, flu is not a mandatory vaccination
2020-02-29T00:39:36 < BrainDamage> because it's not a life threatening disease in general
2020-02-29T00:39:40 < jadew> yeah, the other ones are mandatory here as well
2020-02-29T00:39:40 < Cracki> flu isn't deadly enough
2020-02-29T00:39:46 < jadew> yep
2020-02-29T00:39:52 < Cracki> because they kill or debilitate a lot more

2020-02-29T00:40:04 < Steffanx> I'm not sure if any vaccination is mandatory here. I recall it's not 
2020-02-29T00:40:08 < Cracki> and the state has a vested interest in not allowing people to turn themselves or their kids into vegetables
2020-02-29T00:40:16 < Cracki> because that costs money
2020-02-29T00:40:46 < jadew> Steffanx, they are here and you can't enroll your kid in school if he's not vaccinated (at least at our school)
2020-02-29T00:40:51 < BrainDamage> the state won't forcibly jam a needle in your arm, but just like you need a driving license to access public roads, you need mandatory vaccinations to access public school
2020-02-29T00:41:12 < jadew> oh, maybe it's similar in here
2020-02-29T00:41:14 < BrainDamage> you can make your choice to live outside the society to not abide its rules
2020-02-29T00:41:30 < jadew> but it's mandatory to take your kid to school
2020-02-29T00:41:43 < Cracki> do you guys have home schooling or private schools
2020-02-29T00:41:46 < jadew> so I guess vaccines are also mandatory, even if indirectly
2020-02-29T00:41:52 < BrainDamage> it's mandatory to take your kid to a school, not public schools
2020-02-29T00:41:56 < Cracki> school isn't always public
2020-02-29T00:42:01 < BrainDamage> you can go to a private institution
2020-02-29T00:42:21 < PaulFertser> Cracki: what if you jab a needle yourself?
2020-02-29T00:42:31 < Cracki> you can take your kid to a school that doesn't have drag queen story hour every day
2020-02-29T00:42:33 < jadew> I don't think we have home schooling, but we do have private schools
2020-02-29T00:42:40 < Cracki> PaulFertser, that I may tolerate.
2020-02-29T00:42:56 < aandrew> Cracki: here it’s a booster recommended every decade for adults, most forget (like me)
2020-02-29T00:43:04 < Cracki> it's like when I was little and my mother still cut my nails. I hated it. because nobody else knows what it feels like.
2020-02-29T00:43:49 < Cracki> yeah when are you gonna step into a rusty nail, that never happens
2020-02-29T00:43:58 < PaulFertser> "drag queen story hour"? What's that?
2020-02-29T00:43:59 < jadew> I did that
2020-02-29T00:44:01 < aandrew> here flu shot is highly recommended and available freely everywhere but not mandatory, and we also have other optional vaccines (chicken pox, HPV, etc.)
2020-02-29T00:44:04 < Cracki> gardening and home improvement maybe, not keyboard work :P
2020-02-29T00:44:10 < jadew> I stepped on a rusty nail as a kid
2020-02-29T00:44:12 < Cracki> PaulFertser, you're blessed for not knowing
2020-02-29T00:44:14 < jadew> didn't get any vaccines tho
2020-02-29T00:44:21 < BrainDamage> the rusty nail is a bit of a myth
2020-02-29T00:44:25 < BrainDamage> rust has nothing to do
2020-02-29T00:44:28 < BrainDamage> just dirt
2020-02-29T00:44:29 < Cracki> I figured :P
2020-02-29T00:44:30 < aandrew> Cracki: that drag queen bs is overblown like most other things in the media
2020-02-29T00:44:33 < PaulFertser> Cracki: probably so. So what's that?
2020-02-29T00:44:34 < jadew> yeah, you can get it from anywhere
2020-02-29T00:44:42 < jadew> got a tetanos shot later on, when I got bit by a dog
2020-02-29T00:44:52 < PaulFertser> Cracki: do they watch some drag queen TV show every day at school or what?
2020-02-29T00:44:52 < BrainDamage> i also stepped on a rusty needle when I was a kid
2020-02-29T00:44:53 < aandrew> I specifically remember a story time with an old woman missing an arm
2020-02-29T00:45:07 < Cracki> PaulFertser, it's when men dressed up as slutty women approach little children and tell them things
2020-02-29T00:45:15 < aandrew> rusty needle? aren’t those things supposed to be stainless?
2020-02-29T00:45:19 < Cracki> literally, in libraries and schools
2020-02-29T00:45:30 < BrainDamage> not injection needle, sewing needle
2020-02-29T00:45:33 < Cracki> chinesium needles may be made from rust
2020-02-29T00:45:42 < PaulFertser> Cracki: what kind of things? How often does it happen? How about the other artists, do they get an hour too?
2020-02-29T00:45:50 < Cracki> heheh
2020-02-29T00:45:51 < jadew> Material: Rust, nickel plated.
2020-02-29T00:46:18 < aandrew> Cracki: you’re blowing it out of proportion as well
2020-02-29T00:46:25 < aandrew> “dressed as slutty women” - honestly
2020-02-29T00:46:28 < BrainDamage> it was a beach house, with several apartment and balconies, the ground below was sand and directly accessing the beach
2020-02-29T00:46:35 < Cracki> that is what drag queens aim for
2020-02-29T00:46:39 < BrainDamage> probably fell from a balcony
2020-02-29T00:46:42 < Cracki> I should know, I'm gay and associate with those people
2020-02-29T00:46:46 < jadew> BrainDamage, did you get a shot?
2020-02-29T00:46:58 < aandrew> it’s a lot closer to burlesque than stripper, but even burlesque is overhyping it
2020-02-29T00:47:15 < Cracki> now that's splitting needles :>
2020-02-29T00:47:16 < aandrew> theyr’e dressed in princess dresses and flamboyant shit but “slutty” is not it
2020-02-29T00:47:18 < BrainDamage> jadew: you get a serum shot, it's not a vaccine
2020-02-29T00:47:30 < jadew> for anti-tetanos?
2020-02-29T00:47:33 < BrainDamage> yes
2020-02-29T00:47:36 < PaulFertser> Cracki: I seriously do not get it. How often and what kind of meetings is organised in Germany public schools?
2020-02-29T00:47:54 < jadew> interesting, what does it contain, do you know?
2020-02-29T00:48:05 < jadew> anti bodies?
2020-02-29T00:48:06 < BrainDamage> it's kind of prepackaged cultivated immune system cells
2020-02-29T00:48:14 < jadew> neat
2020-02-29T00:48:23 < Cracki> https://cdn.christianpost.com/files/cache/image/12/03/120372_w_450_388.jpg
2020-02-29T00:48:55 < Cracki> if I said daily or weekly, that was OBVIOUSLY hyperbole
2020-02-29T00:49:38 < BrainDamage> jadew: it also contains antibodies and antibodies only to stimulate your own immune system response
2020-02-29T00:50:11 < PaulFertser> Cracki: so what about the other artists? Are they also getting their hour to tell kids about their job?
2020-02-29T00:50:13 < BrainDamage> so that it start replicating T-killer cells with the right genetic target

2020-02-29T00:51:14 < PaulFertser> Cracki: so what are they talking about?
2020-02-29T00:51:20 < aandrew> Cracki: you did, but then said the hyperbole was about daily/weekly

2020-02-29T00:53:18 < PaulFertser> I would hesitate if I was to decide whether to admit Keil and Windows propoganda in schools though.
2020-02-29T00:53:18 < jadew> I like them too, but, as a father in the audience, I would have liked it more if the horny creature was played by a woman

2020-02-29T00:53:41 < Cracki> yes, we need schools without windows

2020-02-29T00:53:59 < jadew> PaulFertser, schools are already doing windows, autocad, etc, propaganda
2020-02-29T00:54:07 < jadew> depends on who gives them the best deals
2020-02-29T00:54:15 < Cracki> wish I had autocad propaganda in my school

2020-02-29T00:55:39 < jadew> their input system was great tho, I liked it
2020-02-29T00:55:40 < aandrew> BrainDamage: not carbon. it’s special paper that you put under your original and run thorugh a machine that bathes the papers in this mist of chemical. copy is blue
2020-02-29T00:55:41 < Cracki> we need to draw the line somewhere

2020-02-29T01:46:45 < zyp> nice
2020-02-29T01:48:45 < kakimir> Cracki: yes. and with only one yellow wire from motherboard
2020-02-29T01:48:49 < kakimir> hp crap
2020-02-29T01:48:55 < kakimir> weird stuff like that
2020-02-29T01:49:23 < Cracki> frightening. "one yellow wire" may be rated for 7-8 amperes
2020-02-29T01:49:49 < Cracki> so unless this is a rather low power card, you can melt something or voltage drops

2020-02-29T01:59:37 < jadew> BrainDamage, you asked for more qualified opinions on this: https://well.blogs.nytimes.com/2016/10/28/does-the-flu-provide-better-immunity-than-a-flu-shot/
2020-02-29T01:59:50 < jadew> Further, natural immunity to one flu virus won’t protect you from most other strains of the virus. “If you were infected with a specific flu virus, your natural immunity would be very good at protecting you against that virus or a similar virus in the future,” says Dr. Fry.
2020-02-29T02:00:30 < doomba> Further, propagating assertions that you will get sick will almost ensure that you do get sick.
2020-02-29T02:01:04 < jadew> doomba, what?
2020-02-29T02:01:12 < antto> we should do what M$ does with "viruses"
2020-02-29T02:01:14 < antto> EEE
2020-02-29T02:03:00 < jadew> also, make sure to read the first paragraph of the answer
2020-02-29T02:04:21 < jadew> so skipping the flu vaccine if you're in a low risk category is not that bad of an idea
2020-02-29T02:05:33 < jadew> some comments on that page do make a couple of fair points: if you interact with people that are in higher risk categories and are not vaccinated, you should probably get vaccinated
2020-02-29T02:05:57 < jadew> but the better option would be to have them vaccinated
2020-02-29T02:06:26 < qyx> can vaccination hurt according to the page?
2020-02-29T02:06:31 < qyx> (I did not read it yet)
2020-02-29T02:06:56 < jadew> qyx, it doesn't address that

2020-02-29T02:17:52 < zyp> do you have hair like that?
2020-02-29T02:17:57 < jadew> funny
2020-02-29T02:18:07 < doomba> jadew: i'm a firm believer in the pseudo-science of mind over matter. the mind controls the immune system, like everything else in the body. when the mind is constantly attacked with negativity and fear-porn, the immune system will "accept defeat" and lead to physical ailments.
2020-02-29T02:18:51 < Cracki> the mind controls the hair color
2020-02-29T02:18:56 < kakimir> wher lurence
2020-02-29T02:19:07 < doomba> the same goes for constantly attacking the body with unnatural medications and sanitizers.
2020-02-29T02:19:13 < doomba> soaps, shampoos, etc.
2020-02-29T02:19:17 < Cracki> they took him! to the quarantine brothel!
2020-02-29T02:19:28 < doomba> which is why i only use all-natural soap, toothpaste, etc.
2020-02-29T02:19:45 < jadew> doomba, you mean that argile based toothpaste?
2020-02-29T02:19:52 < jadew> ffs... it's like brushing your teeth with sand
2020-02-29T02:19:57 < doomba> no. i use baking soda and peroxide basically.
2020-02-29T02:20:02 < doomba> tooth powder
2020-02-29T02:20:08 < doomba> not toothpaste
2020-02-29T02:20:24 < doomba> not only do i think it's healthier, but it lasts forever. so it's much more cost effective.
2020-02-29T02:20:26 < Cracki> brb powdering my teeth
2020-02-29T02:20:32 < jadew> lol Cracki 
2020-02-29T02:21:01 < doomba> the abrasiveness of the powder works better than toothpaste imo
2020-02-29T02:21:07 < Cracki> dunno, I'm too lazy to mix my own tooth-something. I just buy product and consume
2020-02-29T02:21:19 < doomba> Cracki: me too. i buy the powder
2020-02-29T02:21:37 < doomba> and for soap, i use the 32oz bottles of dr. bronner. they last months.
2020-02-29T02:21:45 < jadew> we use a different toothpaste every time
2020-02-29T02:21:46 < Cracki> I'm a little angry. there seem to be two types of "soda"
2020-02-29T02:21:56 < jadew> one week we had one that was black
2020-02-29T02:21:57 < Cracki> (not counting the soda that's a beverage)
2020-02-29T02:22:14 < doomba> it's kind of amazing that if you get the right stuff, your total spending on hygeine products goes way down and you feel cleaner and it's better for your body and immune system.
2020-02-29T02:22:16 < qyx> Na2CO3 and NaHCO3?
2020-02-29T02:22:20 < jadew> once you started brushing you would look like a zombie
2020-02-29T02:22:22 < qyx> or something like that
2020-02-29T02:22:27 < Cracki> yes something like that
2020-02-29T02:22:35 < Cracki> and the one is good for baking, the other for other things, ...
2020-02-29T02:22:56 < jadew> doomba, I'll have my wife look into it
2020-02-29T02:23:04 < Cracki> and you have to know the context to know which to use
2020-02-29T02:23:27 < doomba> when you're constantly spreading unilever products all over your body, your skin gets all out of whack. that shit seeps into your blood stream. the fragrances "feminize" you and do all sorts of other neurological things to make you docile and susceptible to illness - which further requires you to buy more products, pharma and otherwise.
2020-02-29T02:23:32 < doomba> it's a perpetual "upsell"
2020-02-29T02:23:35 < jadew> she should know enough chemistry to be able to come up with a new toothpaste
2020-02-29T02:23:47 < jadew> could be good for prepping
2020-02-29T02:23:53 < qyx> :D
2020-02-29T02:24:01 < jadew> instead of buying toothpaste, you buy cans of powders
2020-02-29T02:24:08 < doomba> jadew: look up ecodent
2020-02-29T02:24:18 < doomba> it's a good tooth powder brand. shit lasts forever.
2020-02-29T02:24:28 < Cracki> inb4 government arrests you for having kegs of powder
2020-02-29T02:24:28 < qyx> zyp: did you look into stm32mp1 by any chance?
2020-02-29T02:24:30 < doomba> toothpaste is a joke
2020-02-29T02:24:32 < jadew> hah, so there is already something like that hehe
2020-02-29T02:24:40 < doomba> i'll never go back to toothpaste
2020-02-29T02:24:45 < zyp> qyx, read through some docs a while ago, why?
2020-02-29T02:24:59 < qyx> if reasonable at all
2020-02-29T02:25:10 < doomba> i also dry shave with a safety razor
2020-02-29T02:25:13 < qyx> it is bga :S
2020-02-29T02:25:25 < doomba> using blades made in russia and germany
2020-02-29T02:25:33 < doomba> because they're the best!
2020-02-29T02:25:52 < zyp> qyx, and you get to route ddr ram :)
2020-02-29T02:25:58 < qyx> that too
2020-02-29T02:26:26 < doomba> no shaving cream - and the blades last for months before they get too dull. so you spend $15 for enough blades to last you like 3 years.
2020-02-29T02:26:33 < zyp> I figure that goes for any SoC, if you want something easier get a module
2020-02-29T02:26:45 < zyp> seems to be quite a few mp1 modules now
2020-02-29T02:26:52 < qyx> also you either get 0.5mm pitch balls nicely spread on the perimeter or a full grid of 0.8mm ones
2020-02-29T02:26:57 < qyx> idk which one is worse
2020-02-29T02:27:07 < zyp> how many balls?
2020-02-29T02:27:17 < doomba> the normies spend $50 on blades every month. and they wonder why they're still broke with their 6-figure learned-helplessness javascript jobs
2020-02-29T02:27:21 < qyx> 257 minimum
2020-02-29T02:27:35 < zyp> hmm, gonna look up the footprints, hang on
2020-02-29T02:27:46 < Cracki> doomba, have an electric razor and I buy a new cutting head maybe once a decade
2020-02-29T02:27:58 < Cracki> that fucker has been with me for at least 15 years
2020-02-29T02:28:12 < doomba> haha yes i have an electric razor too for cutting my hair
2020-02-29T02:28:24 < zyp> okay, so 257 0.5mm or 354 0.8mm
2020-02-29T02:28:27 < qyx> same here, never bought new cutting head
2020-02-29T02:28:30 < Cracki> I have one of those too. can't reach *all* the hair I'd like to trim :>
2020-02-29T02:28:35 < doomba> yep
2020-02-29T02:28:44 < Cracki> brb buying robot parts
2020-02-29T02:29:09 < Cracki> lotsa balls. how many rings of 0.5mm spacing?
2020-02-29T02:29:31 < Cracki> 0.8 sounds "doable" if current state of the art is 0.1mm traces and 0.2mm vias
2020-02-29T02:29:45 < zyp> 354 0.8 looks easy to do on 4L
2020-02-29T02:29:58 < qyx> zyp: you would need 0.05mm trace/clearance for 0.5mm pitched one
2020-02-29T02:30:08 < qyx> pad dia is 0.35mm
2020-02-29T02:30:19 < zyp> pretty much all signals are in the outer four rings, all the center ones are power/gnd
2020-02-29T02:30:33  * qyx looking
2020-02-29T02:31:04 < Cracki> I remember that one pdf where they present various fanouts. four rings was one of the first (and "simplest") fanouts
2020-02-29T02:31:12 < Cracki> I think tehy took two planes for four rings
2020-02-29T02:31:13 < zyp> all the ddr pins are neatly sorted on the right side too
2020-02-29T02:32:12 < zyp> Cracki, if you can run one trace between pads or vias, top layer takes outer two rings, second routing layer takes the next two, then each layer past that adds another ring
2020-02-29T02:32:22 < Cracki> ye
2020-02-29T02:32:50 < zyp> so 4L is enough for four rings
2020-02-29T02:32:59 < zyp> signals on top and bottom, ground and power on inner planes
2020-02-29T02:36:25 < qyx> but if I had to do bga with ddr, I would rather look into allwinners
2020-02-29T02:36:40 < qyx> if china ever returns to normal
2020-02-29T02:37:13 < kakimir> I'm planning to use bga stm32
2020-02-29T02:37:21 < zyp> I still wanna do a fpga board with a sodimm socket
2020-02-29T02:37:27 < kakimir> qfp so ugli
2020-02-29T02:38:27 < zyp> ddr sodimms are a triple digit number of signals, so that's gonna be fun to route
2020-02-29T02:38:39 < qyx> also, why are there such low limits on the amount of dram
2020-02-29T02:38:54 < qyx> mappable on the stm32mp1 for example
2020-02-29T02:39:09 < qyx> it has AXI, shouldn't it be easy to support more?
2020-02-29T02:39:15 < zyp> 32-bit address bus?
2020-02-29T02:39:29 < qyx> but still only 1G supported
2020-02-29T02:39:51 < zyp> you need to fit all the memory mapped peripherals somewhere too
2020-02-29T02:40:09 < qyx> they say 64bit amba axi
2020-02-29T02:40:16 < qyx> idk what does this mean
2020-02-29T02:40:21 < zyp> I think that's data width
2020-02-29T02:40:22 < zyp> not address
2020-02-29T02:41:28 < zyp> speaking of width, apparently ddr3 got 11 signals per byte lane, and a sodimm is 64-bytes wide, so that's 88 signals
2020-02-29T02:41:46 < zyp> and then a bunch of address and control signals as well
2020-02-29T02:42:58 < qyx> it has hardware virtualization O_o
2020-02-29T02:43:59 < zyp> hardware virtualization is just a fancy way to say dual level MMU

2020-02-29T05:01:16 < englishman> here's a theory
2020-02-29T05:01:23 < englishman> most people who have coronavirus aren't even tested
2020-02-29T05:01:29 < englishman> because it is so harmless
2020-02-29T05:01:41 < englishman> of the people sick enough to get tested, the death rate is a rather high 2%
2020-02-29T05:02:19 < englishman> you probably already caught coronavirus and got better because coronavirus ain't shit
2020-02-29T05:09:32 < emeb_mac> interesting idea
2020-02-29T05:11:01 < emeb_mac> about 4wks ago wife & I went to a convention in a nearby city - lots of folks from all over the world there. Got back home and a few days later we both came down with flu-like symptoms. 
2020-02-29T05:11:13 < emeb_mac> (note we both have had this year's flu shot)
2020-02-29T05:11:46 < emeb_mac> took ~1wk to get over the fever & aches, several more weeks to get over the coughing etc.
2020-02-29T05:12:11 < englishman> who goes to the hospital for the flu anyway
2020-02-29T05:12:17 < emeb_mac> right?
2020-02-29T05:12:39 < englishman> i had the same thing, just coughing up the last oysters now
2020-02-29T05:13:00 < emeb_mac> and of course here in the US the (unreliable) CV test costs like $4k
2020-02-29T05:40:33 < catphish> englishman: what's the theory? those just seem like facts
2020-02-29T05:41:02 < englishman> as factual as any other theory: reading it on the internet = truth
2020-02-29T05:41:32 < catphish> i imagine you'd know if you *didn't* have it though
2020-02-29T05:41:48 < catphish> flu is unpleasant, even for fit healthy adults
2020-02-29T05:44:29 < englishman> so are taxes
2020-02-29T05:45:03 < catphish> true that
2020-02-29T05:45:26 < catphish> know any good ways to avoid them?

2020-02-29T08:01:30 < upgrdman> if the p-mos was weaker, i could understand the rising edges always being slower, but on the right side of that eye, the rising edges are plenty fast.
2020-02-29T08:11:51 < upgrdman> o nm, i guess it because of expo fall off or rise. the last half of the edges takes longer.

2020-02-29T16:21:03 < Cracki> are you asking how to do pcb surgery
2020-02-29T16:21:22 < Mangy_Dog> no firstly is there anyway to get into rgb mode without those pins
2020-02-29T16:21:40 < Cracki> so you're asking about the operation of some IC?
2020-02-29T16:22:00 < Mangy_Dog> cracki have you read the post? its all very clear
2020-02-29T16:22:03 < Cracki> browse data sheet
2020-02-29T16:23:38 < Cracki> there is no link to any data sheet for an IC, only shop link and another shop link
2020-02-29T16:23:51 < Mangy_Dog> no
2020-02-29T16:24:03 < Mangy_Dog> the shop link shows all th datasheets on that page
2020-02-29T16:24:08 < Mangy_Dog> the second link is direct to the init code
2020-02-29T16:24:30 < Cracki> is the init code relevant? you're asking... if this thing can be talked to solely via i2c, right?
2020-02-29T16:24:46 < Mangy_Dog> No
2020-02-29T16:24:51 < Mangy_Dog> you clearly havent read my post

2020-02-29T16:34:49 < invzim> coil in bucks, do you need to go into the nitty gritty or is it a bit like decoupling that you find 1 or 2 value of caps that work 99.9% of the time?
2020-02-29T16:35:45 < invzim> http://www.ti.com/tool/BUCK-CONVCALC - nice excel tool, but doesn't really agree with datasheets I think
2020-02-29T16:37:30 < doomba> usually the datasheets have a chart with part numbers for recommended coils to use

2020-02-29T16:40:15 < invzim> sheet suggests something like 30uH
2020-02-29T16:41:16 < doomba> then you gotta find out switching current
2020-02-29T16:41:32 < invzim> but that depends on actual load no?
2020-02-29T16:42:10 < doomba> yeah so you want to know the maximum switching current and your tolerable ripple current under the load you expect
2020-02-29T16:43:02 < doomba> "When selecting the inductor, make sure it is able to handle the peak current without saturation at the highest operating temperature. "
2020-02-29T16:43:56 < invzim> yeah, that's but the inductance.  Sheet seems to suggest that higher loads requires less inductance
2020-02-29T16:44:27 < invzim> no, current :)

2020-02-29T16:45:38 < Laurenceb> simulate the starship with javascript
2020-02-29T16:45:40 < zyp> invzim, peak current scales with load current
2020-02-29T16:45:58 < Laurenceb> use agile
2020-02-29T16:46:26 < zyp> invzim, consider this; peak current feeds the load plus enough current to charge the cap
2020-02-29T16:46:48 < zyp> cap charging current depends on duty, which depends on Vin/Vout relationship
2020-02-29T16:48:52 < invzim> An intuitive way of thinking about lower load=higher inductance req?
2020-02-29T16:49:59 < invzim> wait, is nominal output current same as quiescent current?
2020-02-29T16:51:04 < invzim> no, that makes it all messed up

2020-02-29T17:04:11 < doomba> AIOSH = Artificial Intelligence Occupied Synthetic Humanoid
2020-02-29T17:07:16 < Thorn> invzim: in my experience the higher Vin - Vout the higher the required inductance. another factor is where you want the dcm/ccm threshold to be
2020-02-29T17:08:43 < invzim> Thorn: math, intuition or testing?
2020-02-29T17:09:02 < Thorn> math applied to multiple deesigns

2020-02-29T17:12:54 < invzim> allreet, guess I will have a few prototypes of this thingie before it works the way I want :)
2020-02-29T17:16:54 < Thorn> buck is the  topology that is the least sensitive to inductance so most values will work as long as you don't saturate the core too much

2020-02-29T19:00:48 < Cracki> fewer students have a car to buy lots at a time
2020-02-29T19:01:18 < doomba> jpa-: yea that's the diff. i'm not in a city but i'm in an area where people don't need to think ahead when they shop - because they're not driving 2 hours to go grocery shopping.
2020-02-29T19:01:24 < jpa-> kakimir: eh, this channel has been ##corona32 for over a month already
2020-02-29T19:01:26 < Cracki> pandemonium more than pandemic
2020-02-29T19:01:42 < kakimir> when I lived in a city once I drove a bus 200meters to my appartment because I had too much shoppings
2020-02-29T19:01:59 < kakimir> and I paid 2euros
2020-02-29T19:02:10 < jpa-> i should have stocked up on PCBs, i almost ran out this month due to the pandemic
2020-02-29T19:02:10 < qyx> heh at parent's house, if they start to eat what their basement contains, it should last for few months
2020-02-29T19:02:46 < qyx> I can't get sama5d27 SOMs :(
2020-02-29T19:03:06 < jpa-> i could probably also catch enough fish to feed us :P
2020-02-29T19:03:32 < jpa-> once the full apocalypse hits and we are the only surviving people in the city, that is
2020-02-29T19:05:12 < englishman> I think I have food for 2 years

2020-02-29T19:06:27 < jpa-> Cracki: 70 degrees should be enough, but i'd recommend 75 deg C to be sure unless you're after the culinarist fleshy feel of a good human steak

2020-02-29T19:07:06 < kakimir> how is electronics components and pcb?
2020-02-29T19:07:09 < Cracki> fits nicely with the guesstimated 10%
2020-02-29T19:07:15 < kakimir> if I wanted to order in a week or so
2020-02-29T19:07:42 < jpa-> kakimir: jlcpcb seems to be picking up speed now, lcsc worked fine, digikey etc. were never affected anyway
2020-02-29T19:08:00 < Cracki> would surprise me if people "hamstered" electronics staples
2020-02-29T19:08:04 < doomba> my last jlcpcb order shipped in a day - but i'm still waiting for it to be delivered.

2020-02-29T19:09:26 < qyx> I am going to order components when submitting PCBs for manufacturing
2020-02-29T19:10:18 < qyx> it starts to occur that a component is not available anymore when the boards arrive
2020-02-29T19:10:30 < qyx> so I am not able to assemble few prototypes
2020-02-29T19:10:47 < jpa-> i always do that anyway, as the shipping times are close enough
2020-02-29T19:11:12 < qyx> meh, mouser comes in 2 days, tme in 1 day, PCBs in a week or two
2020-02-29T19:11:31 < qyx> but mouser is undeterministic nowadays for some reason
2020-02-29T19:12:19 < qyx> they are starting to have shortages of some common components I use

2020-02-29T19:48:59 < kakimir> i said it before

2020-02-29T19:49:27 < kakimir> and I have learned a lot about them

2020-02-29T19:52:06 < englishman> 32bit parallel bus = 32 sma connectors in a row
2020-02-29T19:52:14 < jpa-> zyp: just happens to
2020-02-29T19:52:41 < zyp> I have no idea how many days I've got food for in my house
2020-02-29T19:53:25 < kakimir> 0-1
2020-02-29T19:53:53 < zyp> and it also depends how you count
2020-02-29T19:54:25 < zyp> we normally buy 20kg bags of rice, and you could technically survive pretty long on that
2020-02-29T19:55:12 < jpa-> yeah, i'd be counting calorie intake only and even that at the basic level and not heavy exercise level
2020-02-29T19:55:57 < englishman> how long can you survive on 1200 calories a day or more importantly how long will you keep the will to live
2020-02-29T19:57:01 < zyp> according to a google search, rice is 4 calories per gram, so 20kg of rice alone provides 40 days worth of calories
2020-02-29T19:57:36 < Steffanx> Fresh water and rice is all you need.
2020-02-29T19:58:04 < jpa-> englishman: sometimes i can barely keep the will to live in normal situations, so that might be too much to ask for :P

2020-02-29T20:01:30 < doomba> but you'll live
2020-02-29T20:01:50 < doomba> i've gone 18 months with only about 1500 calories per day.
2020-02-29T20:02:12 < jpa-> zyp: surprisingly there seems to be a difference between depressed finn and happy finn
2020-02-29T20:02:26 < doomba> i was pretty weak. not REALLY week but definitely did not have much strength.
2020-02-29T20:02:38 < Steffanx> why would you do that doomba?
2020-02-29T20:02:38 < jpa-> zyp: but maybe it is one of these cases that "all those foreigners look alike" when you haven't trained to detect the subtle differences
2020-02-29T20:02:48 < doomba> Steffanx: didn't have a choice. was in jail.
2020-02-29T20:03:09 < jpa-> they don't give enough food in jails there?
2020-02-29T20:03:24 < doomba> though when i transferred out of that place to a place where i could get more calories, my strength came back really fast. it only took like 2 weeks and i felt "normal" again.
2020-02-29T20:03:47 < doomba> jpa-: privately run jail. so no.
2020-02-29T20:04:17 < Steffanx> Nice way of managing people :)
2020-02-29T20:04:26 < doomba> they give only enough food so people don't die
2020-02-29T20:04:33 < doomba> i lost over 100lbs

2020-02-29T20:07:02 < zyp> apparently we've got 15 confirmed cases in norway now
2020-02-29T20:07:49 < zyp> I take that as a sign I shouldn't be worried about going to japan in a week, since 15 is a larger amount of norway's population than 241 is of japan's population
2020-02-29T20:07:54 < Steffanx> dont die zyp

2020-02-29T20:52:12 < zyp> I used 1811 kWh in january and 1650 kWh in february
2020-02-29T20:54:33 < Thorn> electric heating?
2020-02-29T20:54:36 < zyp> then again I don't seem to have a lot of seasonal variation, so I guess I'm not really using so much energy for heating; https://bin.jvnv.net/file/swnER.png
2020-02-29T20:54:37 < englishman> 8.5MWh heat, 1.15MWh cars, 0.6MWh hot tub, 0.4MWh hot water tank
2020-02-29T20:55:47 < englishman> low -25.91°C, high 8.61°C
2020-02-29T20:56:54 < qyx> BrainDamage: actually I want to play with a fiber bragg grating sensor
2020-02-29T20:57:31 < qyx> I am thinking of a LED + two detectors with overlapping spectral responses

2020-02-29T21:40:18 < aandrew> got kicad schematics are ugly as fuck
2020-02-29T21:40:38 < aandrew> I used to think Eagle was bad, but kicad actually beat them on the ugliness scale
2020-02-29T21:40:48 < qyx> I like them
2020-02-29T21:40:50 < qyx> can you show?
2020-02-29T21:41:21 < aandrew> any kicad schematic
2020-02-29T21:41:23 < aandrew> never seen a nice one
2020-02-29T21:41:48 < qyx> https://i.imgur.com/BiHHljO.png
2020-02-29T21:41:51 < qyx> imo not that bad
2020-02-29T21:41:53 < aandrew> fucking bright colours on white, text on top of text, big grid dots
2020-02-29T21:41:58 < aandrew> that's not bad
2020-02-29T21:42:03 < qyx> thats kicad
2020-02-29T21:42:08 < aandrew> fonts are still ugly but at least readible
2020-02-29T21:42:11 < aandrew> legible
2020-02-29T21:42:38 < qyx> it just wants a bit of playing
2020-02-29T21:42:48 < qyx> but yes, defaults settings are ugly
2020-02-29T21:42:50 < aandrew> https://i.stack.imgur.com/OtbiA.png shit like this

2020-02-29T21:43:38 < englishman> haha
2020-02-29T21:43:56 < englishman> what the shit is that
2020-02-29T21:44:04 < englishman> how come not every junction has a dot
2020-02-29T21:44:23 < englishman> also what is a net name
2020-02-29T21:44:35 < qyx> englishman: yeah that tps is great
2020-02-29T21:45:09 < englishman> NRF204LOL
2020-02-29T21:45:55 < aandrew> I like every junction having a dot, although I also subscribe to "do not ever use 4-way junctions unless absolutely necessary" as well so dots aren't necessary

2020-02-29T22:37:32 < zyp> IIRC in eagle dots had to be placed manually, is kicad also like that?
2020-02-29T22:39:16 < zyp> ah, the junction englishman appears to seems to be multiple wires hooking up to a schematic pin
2020-02-29T22:39:21 < Thorn> Altium Disaster seems to place dots whenever it feels like it
2020-02-29T22:39:42 < Thorn> even when the 2 wires are assigned to 2 different named nets
2020-02-29T22:40:00 < zyp> Thorn, whenever more than two wires connect to a point, which is the sane default
2020-02-29T22:40:42 < zyp> i.e. if they are connected, there's a dot
2020-02-29T22:41:15 < Thorn> IIRC when I draw a wire that crosse another it doesn't join them, but then when I select and move a part if schematics it starts putting dots on those junctions
2020-02-29T22:41:24 < Thorn> s/if/of/
2020-02-29T22:41:46 < zyp> if you move a part so the pins intersect a wire then yes, it will connect and thus form a dot
2020-02-29T22:42:27 < zyp> imagine it connecting and not showing a dot
2020-02-29T22:42:49 < zyp> (like that kicad screenshot)

2020-02-29T23:11:32 < jadew> math models are suggesting 57 million dead this year alone, from the ncov
2020-02-29T23:11:46 < jadew> that's worse than the spanish flu
2020-02-29T23:12:15 < jadew> unless somehow it gets stopped or delayed enough
2020-02-29T23:13:23 < Thorn> first death in the US is a 19 y.o. football player
2020-02-29T23:13:24 < jadew> actually, between 25 million and 57 million, assuming a death rate between 1% and 2.4%
2020-02-29T23:13:45 < jadew> Thorn, yeah, heard that he was young
2020-02-29T23:14:34 < Cracki> why did he die
2020-02-29T23:14:38 < Cracki> aids?
2020-02-29T23:14:43 < Cracki> drugs?
2020-02-29T23:14:58 < Cracki> fucked up body?
2020-02-29T23:15:25 < Cracki> jadew, you're assuming that everyone gets it. I would say that's not the case.
2020-02-29T23:15:47 < Cracki> cases in wuhan are far far away from covering the population
2020-02-29T23:15:51 < jadew> the math models are suggesting that 30% of the world population is going to get it in the first year
2020-02-29T23:16:50 < Cracki> hubei: 66k confirmed cases, 58.5 million
2020-02-29T23:17:20 < jadew> let's wait for the results from europe
2020-02-29T23:17:24 < Steffanx> and there we go AGAIN.
2020-02-29T23:17:26 < Cracki> that's 0.11% so far, at ground zero
2020-02-29T23:17:42 < Thorn> they turned it into a prison, most people weren't working. that is unsustainable long term
2020-02-29T23:18:09 < Cracki> ok, pick a region
2020-02-29T23:18:20 < jadew> Italy
2020-02-29T23:18:22 < Cracki> I'd like to see any region with above 1% infected
2020-02-29T23:18:28 < jadew> let's see what happens there
2020-02-29T23:18:36 < Thorn> other regions are just starting
2020-02-29T23:19:10 < jadew> so far, several people that came from no-risk regions in Italy, have tested positive in here
2020-02-29T23:19:27 < jadew> which suggests the situation is much worse than reported
2020-02-29T23:19:46 < Cracki> someone speculated that many more people are infected but the sickness progresses so mildly that they don't suspect anything and don't seek medical care
2020-02-29T23:19:50 < jadew> by several, I mean 2 :P
2020-02-29T23:20:05 < Cracki> how much food have you stocked yet

2020-02-29T23:20:29 < jadew> I thought her how to maul them to death
2020-02-29T23:20:41 < jadew> we don't have guns
2020-02-29T23:20:43 < Cracki> is she a... dog?

2020-02-29T23:21:27 < jadew> hah
2020-02-29T23:22:04 < jadew> I think that rather then getting there, the quarantine would get lifted and we'll just sacrifice 5% or whatever of the population
2020-02-29T23:22:35 < jadew> I don't expect more than 1 month quarantine on a large scale
2020-02-29T23:23:20 < Cracki> if you're older than 50, I'd go pick a box to rest in and decide who's my favorite nephew
2020-02-29T23:23:34 < jadew> haha
2020-02-29T23:23:39 < Cracki> otherwise... hope to inherit!
2020-02-29T23:24:51 < Cracki> according to this, the murican death is a 50yo with preexisting illness https://www.nbcnews.com/news/us-news/1st-coronavirus-death-u-s-officials-say-n1145931
2020-02-29T23:24:54 < Thorn> what if it becomes seasonal and will serve the same role the cliff edge did in Sparta
2020-02-29T23:24:58 < Cracki> any source for the "19yo footballer"?
2020-02-29T23:25:46 < jadew> Cracki, my wife read the same thing, but apparently the information got changed on worldometer
2020-02-29T23:25:46 < BrainDamage> if it becomes seasonal then eventually we'll build immunity to the most virulent form by genetic pressure
2020-02-29T23:26:11 < jadew> yeah, it will become like the flu or it will mutate into a milder variant
2020-02-29T23:26:37 < BrainDamage> near all the population of eu has uber strong resistance to the plague too
2020-02-29T23:26:39 < Steffanx> or it will mutate and kill us all.
2020-02-29T23:26:46 < jadew> or that
2020-02-29T23:26:50 < Steffanx> At least we're finally done with it when it happens.
2020-02-29T23:27:17 < jadew> BrainDamage, I wonder if the swine flu helped at all with the immunity
2020-02-29T23:27:27 < BrainDamage> I'd be much more concerned if a haemorragic fever becomes airborne
2020-02-29T23:27:34 < BrainDamage> those have ~90% mortality
2020-02-29T23:27:40 < Cracki> the 19yo footballer is a case, not a death, right, Thorn ?
2020-02-29T23:27:52 < BrainDamage> plus death by bleeding through every orifice is not my idea of fun
2020-02-29T23:27:59 < jadew> lol
2020-02-29T23:28:02 < Steffanx> Not BrainDamage?
2020-02-29T23:28:16 < Thorn> still better than drowning in your bed
2020-02-29T23:28:44 < BrainDamage> one does not exclude the other, you can choke on your vomit or blood
2020-02-29T23:28:51 < Cracki> do handstands, evacuate your lungs
2020-02-29T23:29:13 < Cracki> I'd buy bondage gear now before the normies do a run for it
2020-02-29T23:29:28 < Thorn> Cracki: iirc someone on twitter said today he died and Trump called him a she
2020-02-29T23:29:42 < Cracki> did anyone check between the legs
2020-02-29T23:29:49 < Steffanx> oh twitter, trump.. we need facts :P
2020-02-29T23:30:11 < Cracki> does this mean trans critters die of the virus?
2020-02-29T23:30:18 < BrainDamage> Cracki: I had to evacuate my own lungs once
2020-02-29T23:30:24 < BrainDamage> as in I was drowning
2020-02-29T23:30:34 < Cracki> water from outside or from own body?
2020-02-29T23:30:52 < Cracki> what worked best to accomplish the task?
2020-02-29T23:31:24 < BrainDamage> lucky I was near the shore, swam there, barely lifted myself up and coughed a lot of water
2020-02-29T23:31:46 < BrainDamage> also, now I can tell you that you really do that woosh sound you hear in the movies in the first breathe
2020-02-29T23:32:26 < BrainDamage> also lifting yourself while wearing 18kg equipment is no easy task
2020-02-29T23:32:30 < BrainDamage> esp while drowning
2020-02-29T23:32:44 < Cracki> sounds like military training
2020-02-29T23:32:48 < Cracki> or scuba diving
2020-02-29T23:32:57 < BrainDamage> I was scuba diving
2020-02-29T23:33:14 < BrainDamage> ironically it wasn't the regulator that broke
2020-02-29T23:33:34 < BrainDamage> I did check all the diving gear
2020-02-29T23:34:00 < BrainDamage> it's the plastic breather, the one that looks like a pipe that broke in the wrong moment
2020-02-29T23:34:17 < BrainDamage> you use that while swimming on the surface to save on tank usage
2020-02-29T23:34:38 < BrainDamage> it broke while I was power swimming and I ended up swallowing a few L of water
2020-02-29T23:35:13 < BrainDamage> the guy that was paired with me ( unless you're a professional, you always swim in pairs ) was super concerned
2020-02-29T23:35:52 < BrainDamage> ironically if my mouthpiece broke underwater it'd have been easier, because I could just flip and use the spare regulator
2020-02-29T23:36:11 < BrainDamage> while on surface your flotation device is fully inflated, and is quite cumbersome
2020-02-29T23:36:24 < BrainDamage> and prevent you to flip over
2020-02-29T23:36:58 < Cracki> I figured turning upside down underwater would let you drain your lungs suitably... unless something keeps you afloat
2020-02-29T23:43:01 < englishman> hey BrainDamage i got a police issue beretta 92s
2020-02-29T23:43:16 < BrainDamage> ohh, does it have burst fire mode?
