2019-09-01T00:00:42 < Cracki> shoulda made him an amazon button that joins, speaks, and leaves
2019-09-01T00:00:48 < srk> sounded like fun at the time, we were in the basement with thick cieling and walls, he was just a bit too sensitive :)
2019-09-01T00:01:14 < Cracki> let me tell you how bass frequencies can travel through solid concrete
2019-09-01T00:01:22 < srk> yet we found a compromise but he started to play unfair by calling cops first :)
2019-09-01T00:01:41 < srk> I know, maybe he was just sleeping on top of our sub
2019-09-01T00:02:01 < srk> (instead of complaining politely)
2019-09-01T00:02:04 < Cracki> all I hear and feel from them is the bass. everything above a few hundred hertz just disappears quickly in air or the brickwork
2019-09-01T00:02:23 < Cracki> let me tell you about cops
2019-09-01T00:03:06 < Cracki> I asked the fucker downstairs once very politely, at 1am midweek, to tone it down. he got aggressive and continued.
2019-09-01T00:03:31 < srk> well yeah, that's a different story
2019-09-01T00:04:54 < Cracki> the one hackerspace I checked out once was in a really old industrial building. down the corridor were some artists, apparently living there even tho zoning says it's illegal. they complain about the noise at night.
2019-09-01T00:05:05 < Cracki> I see why they would, but they can't call the cops
2019-09-01T00:05:28 < srk> well it's a problem to find a good place in the city
2019-09-01T00:05:52 < srk> city was aware about noise issues and decided to do shit about that
2019-09-01T00:06:28 < Cracki> damn, can't find any place that sells wasp or hornet nests
2019-09-01T00:06:37 < Cracki> (apart from empty and fake ones)
2019-09-01T00:06:58 < srk> we eventually moved into commercial space where noise is not an issue anymore but the rent is way too high for non-profit space and its turning the hackerspace into cowork/sweatshop shite
2019-09-01T00:07:39 < Cracki> I'd rather have a productive space than a space that lets hobos shower there regularly
2019-09-01T00:08:09 < srk> it's way more complicated ;)
2019-09-01T00:08:12 < Cracki> I'd advise any space to NOT have a shower
2019-09-01T00:08:17 < Cracki> only a water hose
2019-09-01T00:09:10 < srk> ever visited a squat?
2019-09-01T00:09:12 < Cracki> anyway, spaces attract people that exploit them. I'd rather use work facilities for such stuff.
2019-09-01T00:09:35 < Cracki> the only reason for me to visit a squat would be to evict the inhabitants
2019-09-01T00:10:24 < srk> yeah, ppl who try to exploit a hackerspace, that's one of our main problems I would say
2019-09-01T00:11:18 < Cracki> cz ic
2019-09-01T00:11:21 < Cracki> haskell on mcu
2019-09-01T00:11:23 < karlp> catphish: that's what windex and wvalue are for, the interfeace/index parameter
2019-09-01T00:12:46 < srk> I've visited a squat in Vienna and the shared spaces and kitchen were much cleaner than our space looks most of the time. it also had a cool garden with bar 
2019-09-01T00:13:41 < Cracki> i really wonder how squats work... the structure and discipline should be foreign to the inhabitants
2019-09-01T00:13:42 < srk> different culture, doesn't attract greedy fucks and they actually care about their surroundings, culture, other ppl :)
2019-09-01T00:14:10 < Cracki> I think the larger, in number of people, a "space" becomes the harder it gets to coordinate.
2019-09-01T00:14:26 < Cracki> people actually live in a squat, so that limits the number of people naturally.
2019-09-01T00:14:26 < srk> yes
2019-09-01T00:14:43 < Cracki> a space has a lot more but "smaller" interests, so the most obnoxious ones win
2019-09-01T00:15:33 < srk> our space started as a small one with lots of anarchists, now it turned into totally different thing which actually needs rules to work
2019-09-01T00:15:55 < emeb> New toys in the mail today: https://www.aliexpress.com/snapshot/0.html?spm=a2g0s.9042647.0.0.7d5f4c4dnNX3AY&orderId=104993734489571&productId=33044331902
2019-09-01T00:16:06 < Cracki> my sense of fairness is difficult to express.
2019-09-01T00:16:07 < srk> but some dick ppl have troubles with respecting even the written ones
2019-09-01T00:16:14 < Steffanx> that page is dead emeb?
2019-09-01T00:16:15 < Cracki> kick out then
2019-09-01T00:16:20 < Cracki> unless the rules are shit
2019-09-01T00:16:37 < srk> we wil remind them politely first
2019-09-01T00:16:40 < Cracki> rules must be debatable
2019-09-01T00:16:44 < srk> of course
2019-09-01T00:16:52 < BrainDamage> a good rule is one that you're implicitly compliant by acting as a reasonable individual
2019-09-01T00:16:53 < Cracki> "because I say so" is the most infuriating bullshit ever
2019-09-01T00:17:05 < emeb> Steffanx: try this: https://www.aliexpress.com/item/33044331902.html?spm=a2g0s.12269583.0.0.5f956730Y4Uttq
2019-09-01T00:17:17 < BrainDamage> 2nd link works
2019-09-01T00:17:21 < Steffanx> better
2019-09-01T00:17:37 < emeb> basically an F401 "Blue Pill"
2019-09-01T00:17:41 < emeb> w/ USB-C
2019-09-01T00:17:48 < Cracki> cute, F4 on a gumstick
2019-09-01T00:17:54 < emeb> yup
2019-09-01T00:17:57 < Cracki> look for robotdyn, they have F303CC on a gumstick
2019-09-01T00:18:13 < Cracki> price's maybe 10% more
2019-09-01T00:18:58 < emeb> Plugged in. USB DFU bootloader works fine.
2019-09-01T00:19:13 < Cracki> ah! f401 does 84 mhz
2019-09-01T00:19:24 < emeb> Yes. A bit faster than F303
2019-09-01T00:19:26 < srk> BrainDamage: well we've had to establish a rule to ask before smoking in presence of othe people and it feels kind-of redundant as most reasonable ppl don't need such reminders

2019-09-01T00:20:02 < Cracki> boss wonders how much better an F303 will be compared to an atmega88... hahaha I could have done some magic on the atmega, if it had more than 8k flash
2019-09-01T00:20:56 < Cracki> smoking indoors? I would have banned that already
2019-09-01T00:21:53 < Cracki> implication is that weed smokers are discouraged too
2019-09-01T00:22:10 < Cracki> in a space with tools, intoxication can be dangerous
2019-09-01T00:22:22 < Cracki> I'd apply the same rule to alcohol above beer too
2019-09-01T00:22:42 < srk> yeah, we were weed smokers mostly but some ppl need to put shitload of tobacco into their joints as well
2019-09-01T00:22:51 < Cracki> in that space I used to visit they had a few heavy drinkers, i.e. needing 40+% stuff regularly
2019-09-01T00:23:02 < Cracki> ban tobacco then :P
2019-09-01T00:23:43 < srk> yep, you need to be reasonable and not use CNCs or lathes when intoxicated, that's obvious for most ppl but one accident and all goes to shit
2019-09-01T00:23:45 < Cracki> once these idiots drank and there was a "sword" (metal bar ground "sharp" with a wooden handle) and the one wanted to chop the other dude
2019-09-01T00:23:56 < srk> aww
2019-09-01T00:23:58 < Cracki> I hear there was some blood, but not enough to splatter
2019-09-01T00:24:02 < srk> lovely
2019-09-01T00:24:03 < Cracki> I would have LOVED to see that
2019-09-01T00:24:12 < srk> related https://en.wikipedia.org/wiki/Alcohol_belts_of_Europe
2019-09-01T00:24:12 < Cracki> particualrly because both were jerks
2019-09-01T00:24:17 < srk> :D:D
2019-09-01T00:25:16 < Cracki> these weirdos were definitely in the vodka category, although pretty damn close to france
2019-09-01T00:25:58 < Cracki> accident implies using these tools but being too intoxicated to do it right
2019-09-01T00:26:22 < Cracki> THEY were stumbling drunk and could have simply walked into the tool rack

2019-09-01T00:28:03 < srk> well, natural selection :)
2019-09-01T00:28:04 < Cracki> I'm perving the pics on your wiki. what you guys need is some drywalls to partition that space
2019-09-01T00:28:12 < Cracki> indeed
2019-09-01T00:28:51 < srk> yes, if we manage to pay the stupid high rent we might get to that
2019-09-01T00:29:43 < Cracki> from our student council moving I learned that equally partitioned levels suck. before we had a large room for assemblies and smaller ones for work. now we have no choice.
2019-09-01T00:29:51 < Cracki> turn it into a strip club
2019-09-01T00:30:03 < Cracki> I'm sure some of you are sellable
2019-09-01T00:30:20 < Cracki> or maybe beef up on the makerspace side of things
2019-09-01T00:30:42 < srk> I'm joking we need to fix the sound system and add temporary meth lab 
2019-09-01T00:30:45 < Cracki> a whole rack of 3d printers. you almost literally print money.
2019-09-01T00:30:55 < Cracki> meth lab sounds good
2019-09-01T00:30:58 < srk> few parties and its solved

2019-09-01T00:32:17 < Cracki> that's a good idea actually
2019-09-01T00:34:30 < Cracki> nice neighborhood. I like these houses' facades. only shit where I live.
2019-09-01T00:35:05 < Cracki> *cries* you have trams too
2019-09-01T00:36:04 < srk> yep, was good. we also had few for kicad, openscad.. there are lockpicking workshops running now. I've did some workshops on git & nixos, wanted to do haskell and embedded recently but now I'm bit disgusted by some non-reasonable individuals :)
2019-09-01T00:36:37 < Cracki> how unreasonable are they
2019-09-01T00:37:02 < catphish> karlp: my understanding is that the definition of windex is dependent on the value of bRequest, but the values of bRequest are dependent on the class, but the class varied between interfaces, so how is one supposed to resolve it?
2019-09-01T00:37:03 < srk> trams are cool :D pity there's shitty cycling infra
2019-09-01T00:37:29 < Cracki> topography looks cyclable
2019-09-01T00:37:52 < srk> we will see in the upcoming days/weeks as we step-up the game
2019-09-01T00:40:20 < catphish> karlp: it's the order of resolution that bothers me, the definition of windex is specified in the class documentation, but how do i know what class is being addressed until i know the interface?

2019-09-01T00:46:14 -!- ekaologik [~quassel@p5DC6BD9E.dip0.t-ipconnect.de] has joined ##stm32
2019-09-01T00:46:15 < karlp> I think you're overthinking it.
2019-09-01T00:49:40 < catphish> karlp: i am thinking it as much as possible
2019-09-01T00:49:58 < catphish> but i need an order to process things
2019-09-01T00:50:34 < karlp> so look at request type.
2019-09-01T00:50:39 < karlp> it's onyl a class request if it says it is.
2019-09-01T00:51:06 < catphish> first i look at bmRequestType, this tells me it's a class request
2019-09-01T00:51:22 < karlp> then you look at request.
2019-09-01T00:51:31 < karlp> then that says how you interpret windex/wvalue.
2019-09-01T00:51:43 < karlp> and if you should bne expecting data or not.
2019-09-01T00:52:00 < catphish> then i look at bRequest, but... the values of bRequest are  defines according to the class specification, how do i know what class is relevent?
2019-09-01T00:52:39 < catphish> how do i know if bRequest is according to CDC, or mass storage?
2019-09-01T00:52:56 < Thorn> catphish: class is specified in your device or interface descriptor
2019-09-01T00:53:47 < catphish> Thorn: right, but how do i know which interface the reuest refers to?
2019-09-01T00:54:29 < catphish> assuming i have a CDC and a mass storage interface, how do i know which one the request refers to?
2019-09-01T00:57:08 < Thorn> catphish: wIndex in the setup packet will be set to your interface # iirc
2019-09-01T00:59:22 < catphish> Thorn: that's my understanding too, but afaict the meaning of wIndex is defined only according to the value of bRequest, not globally
2019-09-01T01:00:27 < karlp> yes, but they'll overlap.
2019-09-01T01:00:35 < karlp> "this won't be a problem"
2019-09-01T01:00:45 < Thorn> if bmRT is CLASS | INTERFACE then (1) wIndex is the interface # and (2) bmRequest is decoded according to the relevant class spec, correct me if I'm wrong
2019-09-01T01:00:46 < catphish> perhaps it's the case, that in ALL setup packets, wIndex refers to the interfaace number, but that assumption hurts my brain
2019-09-01T01:00:49 < karlp> if you compare them all you can see the same thing used in the same way, across different request types.
2019-09-01T01:00:59 < karlp> it's not an assumption, it's documentation....
2019-09-01T01:01:11 < Thorn> catphish: no, only if the INTERFACE bit is set in bmRT
2019-09-01T01:01:29 < catphish> if that's specified somewhere, i'm happy
2019-09-01T01:01:40 < karlp> you're dealing iwth classes, they're documented.
2019-09-01T01:02:47 < Thorn> everyone's favorite businessman shopping for commerical real estate in Manhattan, live on youtube https://www.youtube.com/watch?v=VsPnnE0AwAI
2019-09-01T01:03:20 < catphish> if it's the case that when bmRequestType specifies a class interface, then wIndex *always* specifies the interface ID, then i'm happy
2019-09-01T01:03:41 < karlp> all the standard interface and endpoint requests use windex for interface/endpoint
2019-09-01T01:04:15 < karlp> you can then look into the classes you care about, and see if they decided to break that, just to fuck with you, or whether they were sane.
2019-09-01T01:04:26 < catphish> karlp: if that's the case, then i'll make that assumption, but doesn't this seem very barkwards?
2019-09-01T01:04:34 < karlp> no?
2019-09-01T01:04:58 < karlp> I meanb, you get 4 bytes wiuth all you need... and then optionally "data" for stuff.
2019-09-01T01:05:29 < catphish> the point is that i don't know the class until i read wIndex, but the meaning of wIndex is defined by the class
2019-09-01T01:06:03 < Thorn> "The wIndex field is often used in requests to specify an endpoint or an interface." usb20.pdf section 9.3.4
2019-09-01T01:06:13 < catphish> "often"
2019-09-01T01:06:16 < karlp> yes, but your class is not going to do anything dumb just to break you.
2019-09-01T01:06:32 < karlp> "this isn't a problem"
2019-09-01T01:06:38 < catphish> why would anyone design it this way :(
2019-09-01T01:06:52 < Thorn> lol >asking that question about USB
2019-09-01T01:07:07 < karlp> catphish:so what would you have changed then?
2019-09-01T01:07:37 < catphish> i'll assume then that wIndex specifies the interface ID in all cases
2019-09-01T01:07:42 < karlp> no. it doesn'ðt
2019-09-01T01:07:49 < karlp> it does for _interface_ requests
2019-09-01T01:08:03 < catphish> sorry, yes, i meant all interface requests
2019-09-01T01:08:10 < karlp> in all standard requests, and probably all class ones you care about.
2019-09-01T01:08:21 < karlp> and you can go and look at the class docs for the two you care abou tand cheackk, easily.
2019-09-01T01:08:34 < karlp> and you only even have to do that check, if you're doing composite devices.
2019-09-01T01:08:59 < karlp> and given that people hve been rolling composite device sfor years, you can pretty much rely on "this isn't a problem except in my mind"
2019-09-01T01:09:14 < catphish> "so what would you have changed then?" << i'd add an explicit byte to specify the interface or endpoint id after bmRequestType
2019-09-01T01:09:45 < karlp> so you want to waste shit then :)
2019-09-01T01:09:57 < karlp> that byte is called windex ;)
2019-09-01T01:10:21 < catphish> but the meaning of windex is class specific :(
2019-09-01T01:10:27 < catphish> it's circualr
2019-09-01T01:10:29  * karlp sighs
2019-09-01T01:10:40 < karlp> find me a class that breaks, and then I'll care.
2019-09-01T01:11:15 < karlp> the classes basicalyl got told, "here's some stuff, you really should keep the same style as the standard"
2019-09-01T01:11:20 < catphish> i realise now that every class defines bindex to be the interface id, but that's a horrible assumptio
2019-09-01T01:11:22 < catphish> n
2019-09-01T01:11:45 < karlp> I mean, in _Ötheory_ the classes could define new requests that clash with the standard ones too, but they _don't_ because that would be _dumb_
2019-09-01T01:12:09 < catphish> that's not how protocol encapsulatuon is supposed to work :'(
2019-09-01T01:12:36 < karlp> go cry to your cs professor and stop working in the real world?
2019-09-01T01:13:00 < Thorn> oh look
2019-09-01T01:13:01 < karlp> dont' think of classes as encapsulation, but more "let's not put all the pages of the document in the same document"
2019-09-01T01:13:03 < Thorn> Requests may be directed to the device, an interface on the device, or a specific endpoint on a device. This
2019-09-01T01:13:03 < Thorn> field also specifies the intended recipient of the request. When an interface or endpoint is specified, the
2019-09-01T01:13:04 < Thorn> wIndex field identifies the interface or endpoint.
2019-09-01T01:13:20 < Thorn> authoritative enough?
2019-09-01T01:13:28 < catphish> but how could something so dumb pass so many major vendors approval
2019-09-01T01:13:46 < karlp> because it's actually not a problem, just in your head? I can say it again if you like :)
2019-09-01T01:13:54 < Thorn> I assume "When an interface or endpoint is specified" refers to bits in bmRT
2019-09-01T01:14:04 < catphish> Thorn: actually yes, where is that?
2019-09-01T01:14:22 < Thorn> usb 2.0 9.3.1
2019-09-01T01:14:59 < catphish> Thorn: if that's a requirement, that changes everything :)
2019-09-01T01:15:33 < karlp> you didnt' even read it first? you just decided it was broken and complained?

2019-09-01T01:17:52 < catphish> karlp: i'm working according to a variety of tutorals, actually the official specs are much more useful, and while i'm looking at the class specs, i haben't looked at the central USB spec
2019-09-01T01:18:19 < karlp> ahh.
2019-09-01T01:18:30 < Cracki> usb.org/documents is certainly a lot of stuff
2019-09-01T01:18:56 < Cracki> those plaintext-looking fields are actually comboboxes
2019-09-01T01:18:59 < catphish> there's a lot of information, and the official specs don't have the best google-fu

2019-09-01T01:19:41 < catphish> but when i do find the official specs, the information seems superiot

2019-09-01T03:34:18 < Cracki> I had this atx psu for room lighting here... I thought it was just the silent type but its fan didn't manage to spin up. when I gave it a little push it whined unbearably

2019-09-01T03:41:39 < Cracki> I honestly thought it would run without the fan for the few watts I was asking... another psu I salvaged had 1200 rpm minimum at zero load. it wasn't the silent type.
2019-09-01T03:44:19 < specing> Yes, they just don't want to power down their fans
2019-09-01T03:44:27 < specing> I have such consumer gear as well
2019-09-01T03:44:33 < Cracki> ordered some of these 8-pin 12v power headers you see on dual socket mobos, half of one is  P4 connector. they're said to be good for 7-8 amps per pin, so a P4 is already rated for 192 watts.
2019-09-01T03:46:09 < Cracki> 336 watt for the 8-pin "EPS12V"

2019-09-01T07:33:07 < englishman> i hope you are as rich as a chinaman
2019-09-01T07:33:30 < aandrew> still gotta buy a monitor or two out there, and probably a variety of parts since I won't know what I need utnil I'm out there
2019-09-01T07:33:43 < aandrew> englishman: yeah it's not cheap out there that's for damn sure
2019-09-01T07:34:05 < aandrew> found cheap flights between abbotsford and london though (like $200 per leg)
2019-09-01T07:34:07 < englishman> if you thought ontario taxes were high wait til you see BC
2019-09-01T07:34:08 < aandrew> so that's not bad
2019-09-01T07:34:27 < jadew> you do this often?
2019-09-01T07:34:35 < aandrew> jadew: first time
2019-09-01T07:34:40 < dongs> oh my god opensores is truly aids
2019-09-01T07:34:54 < englishman> 20 is pretty good
2019-09-01T07:34:56 < englishman> 200
2019-09-01T07:34:57 < dongs> wget.exe has been broken for years doing wget -r / -m to grab a bunch of files in a folder
2019-09-01T07:35:00 < dongs> and then
2019-09-01T07:35:03 < dongs> i saw some shit recommending httrack
2019-09-01T07:35:06 < dongs> holy fucking shit
2019-09-01T07:35:17 < dongs> this is the worst fucking peice of shit i have ever seen
2019-09-01T07:35:19 < aandrew> oh my inspection microscope is staying too, so I have a couple clip on magnifiers for a cell phone, that's gonna be pure ass but I'm not risking damaging the microscope trying to go back and forth
2019-09-01T07:35:35 < aandrew> dongs: heh
2019-09-01T07:35:40 < jadew> dongs, httrack is a mature piece of software
2019-09-01T07:35:49 < jadew> *opensource software
2019-09-01T07:36:10 < englishman> i think that the httrack website was written fully in gedit
2019-09-01T07:36:10 < aandrew> motherfuck I have some kind of infection in my eye
2019-09-01T07:36:16 < dongs> i think you misspelled manure
2019-09-01T07:36:35 < englishman> maybe you should clean your microscope eyepiece
2019-09-01T07:37:24 < dongs> judew
2019-09-01T07:37:27 < dongs> it has a max transfer rate
2019-09-01T07:37:32 < dongs> which is a REQUIRED number
2019-09-01T07:37:36 < dongs> and its in BITS/SECOND
2019-09-01T07:37:45 < jadew> lol, I don't think so...
2019-09-01T07:37:48 < dongs> and the entry seems to stop entering after about 250k/sec
2019-09-01T07:37:57 < dongs> judew, i am trying to fucking use it right now
2019-09-01T07:37:57 < jadew> I think I used it recently too, don't remember that
2019-09-01T07:38:09 < dongs> i blanked out max transfer shit and it was going at 24k/sec
2019-09-01T07:38:13 < dongs> i filled it wiht 99999 until it beeped
2019-09-01T07:38:16 < dongs> and its maxing out at 250k
2019-09-01T07:38:17 < jadew> maybe you have the new and improved version
2019-09-01T07:38:19 < dongs> fuck this nigger shit
2019-09-01T07:38:21 < dongs> ill just click links in chrome
2019-09-01T07:38:29 < dongs> opensores garbage
2019-09-01T07:38:30 < Cracki> yeah httrack is 90s software
2019-09-01T07:38:40 < Cracki> and they haven't rewritten it since then
2019-09-01T07:38:49 < jadew> I made an extension for downloading everything
2019-09-01T07:38:55 < dongs> just shift-deleted that shti
2019-09-01T07:40:12 < jadew> found it, let me remember what it does, maybe it's going to help you a little
2019-09-01T07:40:42 < Cracki> just wget it :P maybe curl can do that too but who knows
2019-09-01T07:41:02 < jadew> I think I made this extension to extract the links so I can wget them
2019-09-01T07:41:13 < Cracki> wget can do spidering iirc
2019-09-01T07:41:24 < dongs> it doesnt work on my current shitty vps dont know why
2019-09-01T07:41:27 < dongs> it only downlaods one file and stops
2019-09-01T07:41:27 < dongs> i dont care
2019-09-01T07:41:32 < dongs> ill just click links in chrome
2019-09-01T07:41:34 < dongs> im not in a rush
2019-09-01T07:42:23 < Cracki> -l <max level>
2019-09-01T07:42:33 < dongs> thats not the problem
2019-09-01T07:42:41 < dongs> i am literalyl giving it a crappache "index of" page
2019-09-01T07:42:54 < Cracki> hm
2019-09-01T07:42:54 < dongs> -m -np -nd -c http://nigger.com/crap
2019-09-01T07:43:02 < jadew> http://5.12.176.60/stuff/download_links.zip
2019-09-01T07:43:04 < dongs> it works on all other sites but not this shit and i dont care to figure it out
2019-09-01T07:43:16 < Cracki> maybe it has a robots.txt you have to tell wget to fuck
2019-09-01T07:43:23 < dongs> its my fucking site
2019-09-01T07:43:26 < jadew> you go to extensions, enable developer mode, load unpacked and it adds a small icon
2019-09-01T07:43:34 < jadew> then you can filter out all the links it finds
2019-09-01T07:43:37 < jadew> (with regex)
2019-09-01T07:43:52 < Cracki> wget might get a domain name from the server, and only wanna spider that, but not the plain IP...
2019-09-01T07:43:56 < jadew> and you can either copy them and do a wget or ask chrome to download them all
2019-09-01T07:44:08 < Cracki> nvm he posted something with IP
2019-09-01T07:44:56 < jadew> it's a chrome extension btw
2019-09-01T07:47:30 < jadew> http://5.12.176.60/stuff/download_links.jpg
2019-09-01T07:47:45 < dongs> what does download all do
2019-09-01T07:47:53 < dongs> doesnt chrome have a limit of like 6 downlaods per site
2019-09-01T07:48:10 < jadew> it will try to download them all
2019-09-01T07:48:12 < jadew> but be careful
2019-09-01T07:48:36 < jadew> if you don't have a set folder (and it's set to always ask where) it will ask you for every file for the location
2019-09-01T07:50:16 < jadew> I think it was an example extension, not really sure how much I changed
2019-09-01T07:52:19 < jadew> hmm, probably not much, the coding style is stupid
2019-09-01T07:53:37 < Cracki> I think the 6 downloads limit is a concurrent connections limit really
2019-09-01T07:53:51 < jadew> yeah
2019-09-01T07:53:53 < Cracki> and it might even be enforced by the server, not chrome itself
2019-09-01T07:54:28 < jadew> ok, I didn't write it
2019-09-01T07:54:35 < Cracki> it might queue them up, or it might choke
2019-09-01T07:54:35 < jadew> found the original source
2019-09-01T07:55:06 < jadew> looks like I needed it to navigate to all the links so I added that option

2019-09-01T09:11:49 < ThatDamnRanga> If there's one thing that irritates me about mbed... It's the fact they seem to have decided that all objects need FULLINITIALISATION at compile time -_-
2019-09-01T09:12:13 < ThatDamnRanga> Wtf would be the harm in having a default construction and an init function /available/
2019-09-01T09:13:39 < ThatDamnRanga> I don't necessarily want to turn on a peripheral until I've checked that the user wants it enabled...
2019-09-01T09:22:44 < Cracki> can't use RAII but you can still create the instance later and work with pointers
2019-09-01T09:23:16 < Cracki> well you could... assuming they have proper ctors on thsoe things

2019-09-01T10:57:28  * grummund wonders how to go about creating stm32 projects from scratch
2019-09-01T10:57:50 < grummund> like where are you getting gcc linker script and startup code from?
2019-09-01T11:08:45 < srk> you look for 'baremetal' examples 
2019-09-01T11:12:17  * grummund already has a working example but is curious to know what others do
2019-09-01T11:12:47 < srk> I generate all the stuff from cubemx database and svd files
2019-09-01T11:32:25 < dongs> what stuff
2019-09-01T11:37:06 < jpa-> you know, the stuff
2019-09-01T11:42:42 < srk> parts of linker script, startup code (vector table), all the registers

2019-09-01T13:55:23 < ThatDamnRanga> how does /anything/ disappear from ali
2019-09-01T13:57:29 < Thorn> another example: siglent scopes
2019-09-01T13:58:21 < Thorn> and not just scopes, siglent signal generator that I got from ali has been gone for at least a year
2019-09-01T14:01:12 < Steffanx> The one you hack from 40 to 120mhz?
2019-09-01T14:01:19 < Steffanx> Megahurtz
2019-09-01T14:01:32 < Thorn> yes
2019-09-01T14:02:55 < Thorn> maybe lecroy or whatever brand it was didn't like a cheap OEM version being available
2019-09-01T14:03:04 < ThatDamnRanga> Hmm. I've not looked at those. I'm still eyeing up a Rigol scope
2019-09-01T14:03:23 < ThatDamnRanga> I've been getting away with not having a scope of any kind for like 7 years... Not anymore
2019-09-01T14:04:08 < jadew> Thorn, maybe it wasn't worth it so they removed it?
2019-09-01T14:04:12 < Steffanx> I have one too Thorn. Such lunix hacking
2019-09-01T14:04:25 < jadew> or they couldn't source it anymore because siglent gets more money if they sell directly in Europe?

2019-09-01T14:07:38 < jadew> and 100+ MHz
2019-09-01T14:08:56 < Steffanx> That's why you remove some file from the lunix fs and you change 40 to 120
2019-09-01T14:09:31 < Steffanx> It's some zynq based device. arm cores run lunix
2019-09-01T14:09:47 < Steffanx> Or core. Not sure if multiple cores.

2019-09-01T14:41:01 < marble_visions> s/has/does/
2019-09-01T14:43:14 < marble_visions> with the timing register i can modify the clock signal (duty cycle, etc), but i don't see how i can insert a delay between start and address, and between address and first byte

2019-09-01T21:21:30 < jadew> just measured one from ebay and it was 5.9 degrees out at 0 C
2019-09-01T21:24:20 < Thorn> is it 2 wire? long cable?
2019-09-01T21:24:59 < jadew> not extremely long, so I don't think it accounts for the 2 ohm difference
2019-09-01T21:25:40 < jadew> using 4 wire probes to connect to the wires of the sensor
2019-09-01T21:25:51 < Thorn> well even class B is supposed to be within 0.5°C @ room temp
2019-09-01T21:25:52 < jadew> maybe I should cut one up and measure the wires, so I can remove them from the measurement

2019-09-01T22:15:11 < catphish> today's usb question, i'm trying to receive a packet that has a setup part followed by a payload, but i can't work out the correct way to receive both parts, how should this be done on the stm32?
2019-09-01T22:17:26 < catphish> i get an interrupt, and the stm32 has only buffered the first 8 bytes (the setup) packet, the remaining half seems to come in later, do i need to wait for both interrupts?
2019-09-01T22:33:15 < kakimir> Steffanx: why do drives spin up randomly in my NAS?
2019-09-01T22:33:19 < kakimir> nobody is using it

2019-09-02T00:08:45 < catphish> sorry to trouble you again, but i have a question that i stupidly can't find an answer to, how am i meant to respond to CDC interface control requests (such as SetLineCoding)
2019-09-02T00:09:16 < catphish> i want to say "yes, i've set the line settings" but i'm totally missing where these replies are documented
2019-09-02T00:11:02 < aandrew> I've been geeking out to gps disciplined oscilators all afternoon
2019-09-02T00:11:55 < aandrew> found a cheap one on ali that seems to be well liked and then there's a cheap time interval coutner that will get me down to 60-80ps 
2019-09-02T00:19:50 < karlp> catphish: I don't think there is a reply. you do as you're told, period.
2019-09-02T00:20:44 < aandrew> that's correct (according to my memory) -- you store what you were asked to set somewhere but nothing more than just the usual USB ACK
2019-09-02T00:20:59 < aandrew> then when the PC asks you what your settings are you just give it that same info back (if it even asks)
2019-09-02T00:21:11 < catphish> karlp: okie dokie, maybe i'm missing something else, i get "failed to set dtr/rts" errors in my kernel log
2019-09-02T00:21:33 < aandrew> line coding, baud rate, flow control... all of it is irrelavent if you're not actually doing something uart-ish on the other side

2019-09-02T00:24:04 < catphish> just looked at another CDC device, it doesn't respond to that request, guess i've been worrying needlessly, i'll move on to the actual data exchange

2019-09-02T09:15:41 < jadew> I just bought a controleo3
2019-09-02T09:16:13 < jadew> finally started working on my oven controller and realized I really don't want to do that
2019-09-02T09:17:00 < jadew> that cleared up a couple of days I bet
2019-09-02T09:17:49 < dongs> or you could have bought a proper reflow oven
2019-09-02T09:17:50 < dongs> jesus christ.
2019-09-02T09:17:53 < dongs> autism overload
2019-09-02T09:19:12 < jadew> from what I hear a convection oven with a controller is better than those T-9xx ones
2019-09-02T09:19:32 < jadew> and I don't want to pay several k for a proper one
2019-09-02T09:20:33 < jadew> I'm considering also trying vapor phase soldering, apparently all you need is a deep fryer and a bit of piping for the cooling system
2019-09-02T09:20:53 < dongs> vapor phase stoning
2019-09-02T09:21:00 < jadew> but that's only good for like 1 board
2019-09-02T09:21:24 < jadew> (because they don't fit)
2019-09-02T09:21:41 < jadew> if you have smaller ones, you could probably do larger batches
2019-09-02T09:22:05 < jadew> one of the advantages of vapor phase (that makes me want it) is that the boards come out clean
2019-09-02T09:22:19 < jadew> apparently that thing is also a very good solvent for flux
2019-09-02T09:22:29 < jadew> so you don't have to clean them afterwards
2019-09-02T09:24:55 < jadew> anyway, I already have the oven and it's all wired up
2019-09-02T09:25:01 < jadew> all I needed was the controller

2019-09-02T11:49:25 < jadew> what's that translucent/white flux that everyone seems to be using?
2019-09-02T11:49:35 < dongs> yeah iw anna know that too
2019-09-02T11:49:36 < jadew> seems higher quality than the shit I'm using
2019-09-02T11:49:38 < dongs> chinagirl refused to send it to me
2019-09-02T11:49:43 < dongs> apparentely cant be shipped
2019-09-02T11:49:47 < dongs> i might have to ask again
2019-09-02T11:49:50 < jadew> why not?
2019-09-02T11:49:53 < dongs> donno
2019-09-02T11:50:21 < day> jadew: a gel like flux from a syringe?
2019-09-02T11:50:25 < jadew> yeah
2019-09-02T11:50:53 < jadew> from what I've seen it doesn't burn up easily when you heat it, so it's less messy
2019-09-02T11:50:55 < day> i have one from chipquick iirc. but am not a big fan of it
2019-09-02T11:51:09 < jadew> why not?
2019-09-02T11:51:32 < day> basically what happens is the gel helps align the part, then the gel melts and the component swims away :P
2019-09-02T11:52:09 < dongs> its not for soldering, its for removing
2019-09-02T11:52:10 < dongs> or rework
2019-09-02T11:52:16 < dongs> and you dont use it on 0402 resistors
2019-09-02T11:52:22 < dongs> more like connectors or large ICs
2019-09-02T11:52:24 < jadew> yeah
2019-09-02T11:53:27 < day> it has no problem letting a 32pin qfn chip float
2019-09-02T11:54:54 < day> im sure one can make it work somehow. but i personally prefer fluid flux.
2019-09-02T11:56:18 < Cracki> oh, people recommend flux? so far I know I don't need to bother with the convenient cheap aliexpress stuff because that might just be literal snot

2019-09-02T11:57:25 < Cracki> the rossmann repair dude recommends amtech nc 559 tacky flux https://store.rossmanngroup.com/index.php/amtech-nc-559-v2-30-cc-16160.html
2019-09-02T11:57:26 < jadew> and you can find fake one on bangood too
2019-09-02T11:57:46 < Cracki> I'd buy fake if it isn't too fake
2019-09-02T11:57:49 < jadew> https://www.youtube.com/watch?v=iKDAmY9Rdag
2019-09-02T11:58:21 < Cracki> I'd buy from mister rossmann but international shipping from MURICA for a syringe of the stuff is a bit excessive
2019-09-02T12:00:07 < dongs> Cracki: delete that url immediately
2019-09-02T12:00:15 < dongs> fuck rossman and fuck his retarded faggot shot
2019-09-02T12:00:16 < dongs> fuck rossman and fuck his retarded faggot shop
2019-09-02T12:00:20 < day> omg
2019-09-02T12:00:23 < dongs> (shot is right too, thats what I want to do to him
2019-09-02T12:00:30 < day> it cant be.
2019-09-02T12:00:39 < day> dongs and me having the same opinion? D:
2019-09-02T12:01:05 < Cracki> lol
2019-09-02T12:01:06 < jadew> $2 for a freaking needle?
2019-09-02T12:01:10 < jadew> what kind of a ripoff is that
2019-09-02T12:01:11 < Cracki> ¯\_(ツ)_/¯
2019-09-02T12:01:15 < Cracki> he has to beat them off with a stick
2019-09-02T12:01:27 < Cracki> he sits in manhattan
2019-09-02T12:01:33 < jadew> right
2019-09-02T12:01:34 < Cracki> everything is 10x as expensive there
2019-09-02T12:01:40 < jadew> I can buy 100 needles for $2
2019-09-02T12:01:55 < Cracki> sure you can, but he can ask this price because people take the offer
2019-09-02T12:03:35 < jadew> https://youtu.be/iKDAmY9Rdag?t=245
2019-09-02T12:03:41 < jadew> that's where the reviews start
2019-09-02T12:04:43 < dongs> is this a rossman link
2019-09-02T12:05:04 < day> no it's safe
2019-09-02T12:05:52 < dongs> god damn that shit looks amazing
2019-09-02T12:05:58 < dongs> i need to figure out why chinagirl cant send me that shit
2019-09-02T12:06:02 < dongs> wahtever garbage flux i have just becomes yellow
2019-09-02T12:06:06 < dongs> and doesnt flow
2019-09-02T12:06:15 < jadew> dongs, same here
2019-09-02T12:06:24 < day> i think his best video is where he talks about insurances, and why they are totally bad. the guy is completely dillusional
2019-09-02T12:06:46 < dongs> the best video of rossman would be the one where he gets swatted on live stream
2019-09-02T12:06:48 < dongs> and shot
2019-09-02T12:06:51 < Cracki> chinagirl can't send you murican made snot
2019-09-02T12:07:09 < day> filmed on an apple product
2019-09-02T12:07:32 < Cracki> so... what's his arguments as to why insurance is bad? any qualifiers on that statement?

2019-09-02T12:30:37 < day> Cracki: iirc. it came down to "insurances are bad, because the insurer always get more out of it than the buyer on average." Which obv. isn't incorrect per se. But this logic obviously fails for things like car liability insurance, healthcare insurance etc.
2019-09-02T12:31:07 < jadew> I've always got more from my car insurance
2019-09-02T12:31:36 < jadew> had two cars that got totally wrecked in accidents (while parked)
2019-09-02T12:32:01 < jadew> on the first one I got the insurance only ~2 months earlier and got more for the car than what I paid
2019-09-02T12:32:34 < jadew> on the second one I got less, but I still got a lot of money
2019-09-02T12:32:47 < day> you could make the same argument pro gambling :P
2019-09-02T12:32:56 < Cracki> d'oh, insurance _means_ you pay to get rid of risk
2019-09-02T12:33:10 < Cracki> that's an obvious point. if you can take the risk, insurance is pointless.
2019-09-02T12:33:21 < jadew> yeah, I think he might be right tho
2019-09-02T12:33:22 < day> yes
2019-09-02T12:33:29 < day> no
2019-09-02T12:33:32 < jadew> statistically speaking, you're better off without insurance
2019-09-02T12:33:48 < Cracki> it's simple math, add in someone's risk aversion/readiness and you have a decision
2019-09-02T12:33:48 < day> yes IF you can take the risk
2019-09-02T12:34:15 < day> which 99% cant in medical/liability cases
2019-09-02T12:34:25 < jadew> yeah, being able to take the risk should be part of the equation
2019-09-02T12:34:40 < jadew> yeah, medical insurance is ok
2019-09-02T12:34:48 < jadew> car insurance - not always
2019-09-02T12:35:01 < day> car liability - always
2019-09-02T12:35:24 < day> heck it's mandatory pretty much everywhere i believe
2019-09-02T12:35:42 < jadew> in here it's mandatory to have insurance for damages you might cause
2019-09-02T12:35:44 < jadew> not for your own car
2019-09-02T12:35:58 < day> yeah that is what i mean with liability
2019-09-02T12:36:03 < jadew> insurance for your own car can easily buy you a new car in a couple of years
2019-09-02T12:36:12 < day> i dont have that either
2019-09-02T12:36:29 < day> if i cant insta rebuy my car, then it isnt in my price class
2019-09-02T12:38:15 < Cracki> let's say my house burns down with a chance of 10% per year, and that costs me a million. if I have 100k at the bank, which is the *expected* cost per year, I still can't take the chance because I'm fucked if it happens.
2019-09-02T12:38:51 < jadew> but it's not 10%
2019-09-02T12:38:59 < Cracki> 2.71828%
2019-09-02T12:39:27 < jadew> it's probably way less than the chance you have to die while taking a walk
2019-09-02T12:39:27 < Cracki> also let's make it 200k at the bank, so I'm comfortably above expected cost, but comfortably fucked if it happens.
2019-09-02T12:40:05 < Cracki> if I had 100 houses, and 100*200k at hte bank, I *would* expect on average 100*0.1 = 10 houses to burn down a year, and that'd cost me 10 million, but I have 20 million at the bank, so I'm ok
2019-09-02T12:40:15 < Cracki> the chance of 20+ houses burning down is remote.
2019-09-02T12:40:36 < Cracki> compared to the poor shmuck who just has a single house, I am a lot better off
2019-09-02T12:41:05 < Cracki> big numbers smooth things out
2019-09-02T12:41:12 < Cracki> that's insurance.
2019-09-02T12:41:31 < Cracki> wealth is insurance. if you don't have wealth, you have to pay for it.

2019-09-02T12:43:22 < jadew> the odds of something happening makes it a scam
2019-09-02T12:44:19 < jadew> we take chances all the time
2019-09-02T12:44:48 < jadew> for example, in the case of car insurance, instead of pay for car insurance, you could invest the money yourself
2019-09-02T12:44:54 < jadew> (the ones you'd pay for insurance)
2019-09-02T12:45:15 < jadew> over a life time, even if you lose a car or two, like it happened to me, you're still going to come up ahead
2019-09-02T12:45:37 < jadew> and after you have a fund that covers another car, you don't have to put more money into that fund again
2019-09-02T12:46:36 < jadew> Haohmaru, I did and dongs wants to know too
2019-09-02T12:46:49 < jadew> I saw that video and now I know
2019-09-02T12:46:52 < Cracki> flux here
2019-09-02T12:47:05 < Cracki> cheap/free shipping to central europe please
2019-09-02T12:47:15 < Cracki> >made
2019-09-02T12:47:24 < Cracki> how do you make it
2019-09-02T12:47:35 < Cracki> i'd like it to not just run off
2019-09-02T12:47:36 < jadew> spit and polish
2019-09-02T12:47:40 < jadew> emphasis on the spit
2019-09-02T12:47:55 < Cracki> ic ic
2019-09-02T12:48:07 < Cracki> that was what people say chinesium flux is made of
2019-09-02T12:48:21 < jadew> Haohmaru, got a video?
2019-09-02T12:48:25 < jadew> (of the flux working)
2019-09-02T12:48:27 < Cracki> citric acid, does that need cleaning afterwards?
2019-09-02T12:48:45 < Cracki> hmhm
2019-09-02T12:49:28 < Cracki> how long until it damages things? seconds, minutes, hours, weeks?
2019-09-02T12:49:37 < jadew> Cracki, the anc one is available on tme
2019-09-02T12:49:41 < Cracki> good
2019-09-02T12:49:46 < jadew> https://www.tme.eu/ro/en/details/anc559tf_30/fluxes/amtech/
2019-09-02T12:49:51 < jadew> kinda expensive tho
2019-09-02T12:50:01 < jadew> considering other options work the same
2019-09-02T12:50:17 < jadew> Haohmaru, what happens if you don't?
2019-09-02T12:50:40 < jadew> does it turn toxic when burnt?
2019-09-02T12:50:44 < Cracki> hm, looks tolerable. my electronics online shop is asking ~70% of that for off-brand snot
2019-09-02T12:51:00 < jadew> Cracki, heh
2019-09-02T12:51:31 < Cracki> I might ask boss to order some next time
2019-09-02T12:51:37 < Cracki> I dunno what he uses
2019-09-02T12:51:53 < Cracki> yeah fuck rosin flux for electronics work
2019-09-02T12:52:15 < Cracki> for soldering ok, for rework I like the snot
2019-09-02T12:52:39 < Cracki> some ethanol doesn't do the job?
2019-09-02T12:53:00 < Cracki> ethanol in a bowl, then brushie brushie and some sloshing back and forth?
2019-09-02T12:53:06 < Cracki> yes water first
2019-09-02T12:53:12 < jadew> I actually have a problem with the rosin flux inside solder wire
2019-09-02T12:53:14 < Cracki> then alcohol to displace water
2019-09-02T12:53:49 < jadew> SMA connectors are a bitch to solder and I ended up heating that flux so much that it turns dark on the PCB
2019-09-02T12:53:54 < jadew> and it's difficult to clean too
2019-09-02T12:54:14 < jadew> I have to keep the board maybe 10 minutes in the ultrasonic tank
2019-09-02T12:54:59 < jadew> Haohmaru, weird, I never noticed that
2019-09-02T12:55:03 < Cracki> I see chipquik. is that acceptable?
2019-09-02T12:55:12 < jadew> day said it sucks
2019-09-02T12:55:27 < Cracki> I haven't decided if I trust that guy
2019-09-02T12:55:42 < jadew> lol Cracki 
2019-09-02T12:55:44 < day> as i said, imho the chipquik works fine as a flux, just be aware of the floating effect
2019-09-02T12:55:54 < Cracki> ah that, understood
2019-09-02T12:56:33 < jadew> Haohmaru, I know, but it's not something I enjoy doing
2019-09-02T12:56:46 < jadew> I want to spend as little time as possible on the assembly process
2019-09-02T12:58:41 < jadew> Haohmaru, that problem is caused by the flux in the solder wire, not the one I'm adding
2019-09-02T12:59:07 < jadew> oh, the flux isn't causing any issues if it remains there, but it's ugly
2019-09-02T12:59:35 < Cracki> why the fuck is flux labeled as "lead-free"? is there leaded flux?
2019-09-02T12:59:46 < Cracki> I see chipquik lead-free on digikey
2019-09-02T12:59:55 < Cracki> yes, flux, not solder paste
2019-09-02T13:00:14 < jadew> Cracki, lower qty & cheaper: https://www.tme.eu/ro/en/details/anc559v2_10/fluxes/amtech/nc-559-v2/
2019-09-02T13:00:14 < Cracki> or is that for leadfree solders and takes care not to fuck those up
2019-09-02T13:00:16 < Cracki> ah
2019-09-02T13:00:18 < Cracki> curious
2019-09-02T13:00:27 < Cracki> it's speshul
2019-09-02T13:00:45 < Cracki> nice
2019-09-02T13:00:51 < jadew> it's probably a temperature thing
2019-09-02T13:01:00 < Cracki> sounds plausible
2019-09-02T13:01:49 < Cracki> fuckers sell 5g leadfree for 10.72, and 10g regular for 14, as if you don't look at how much you get for the money
2019-09-02T13:02:12 < Cracki> cba
2019-09-02T13:02:27 < Cracki> I'd rather spend the money than get set up for chemistry
2019-09-02T13:02:52 < Cracki> bottle of ipa and wipes to clean the table is enough for now
2019-09-02T13:03:04 < Cracki> >jar
2019-09-02T13:03:15 < Cracki> where would I get a jar? should I order gamer girl pee?
2019-09-02T13:03:54 < Cracki> I'll buy a jar of jam
2019-09-02T13:04:04 < Cracki> looks close enough to flux anyway
2019-09-02T13:04:28 < Cracki> does look interesting, this "lyutenitza"
2019-09-02T13:05:21 < Cracki> if anyone here is crazy enough to try it, I want a video of it
2019-09-02T13:07:40 < Cracki> no, apple jam
2019-09-02T13:07:53 < Cracki> I'd expect the sugar to cause trouble
2019-09-02T13:08:08 < Cracki> unless ou can find apple jam with no sugar... which I can't imagine
2019-09-02T13:08:18 < Cracki> ... there must be sugar-free apple jam
2019-09-02T13:08:23 < Cracki> with sweetener
2019-09-02T13:08:41 < Cracki> that is probably just structural
2019-09-02T13:09:13 < Cracki> I mean to make it viscous
2019-09-02T13:10:34 < Cracki> brb, buying plexiglass from a warehouse because both hw stores only have polystyrene and seem too dumb to order anything else

2019-09-02T19:16:50 < jadew> aandrew, yeah, that's pretty cool
2019-09-02T19:16:58 < jadew> saw it a couple of days ago
2019-09-02T19:17:31 < jadew> Steffanx, you never said, how is that eyepiece graticule?
2019-09-02T19:21:51 < Steffanx> Uh?
2019-09-02T19:22:19 < jadew> the one for the microscope
2019-09-02T19:22:54 < jadew> is my memory failing me?
2019-09-02T19:23:14 < Steffanx> Uhm, I'm not sure what you're referring to. I recall I planned on buying something on aliexpress, but I'm not sure exactly.
2019-09-02T19:23:38 < jadew> it was a long time ago
2019-09-02T19:23:56 < jadew> I thought you got one
2019-09-02T19:24:10 < Steffanx> It was some special eye piece for something, but... what was it?
2019-09-02T19:24:25 < jadew> it was for measuring under the microscope
2019-09-02T19:24:43 < Steffanx> Ah yes. No I guess I never purchased it
2019-09-02T19:24:58 < jadew> problem is that you have to calibrate it whenever you want to use it and it's a bit of PITA
2019-09-02T19:25:06 < jadew> probably works best with fixed objectives

2019-09-03T00:08:53 < karlp> I'm seriously considering setting up a project that automaticalyl squirts water at them.
2019-09-03T00:09:22 < karlp> we have some braindead cat that turned up in the neighbourhood last winter/spring that things it should be shitting on the pavers
2019-09-03T00:10:26 < karlp> mawk: I've said it before, and it seems to be slowly becoming true, even though I hoped I was wrong, 802.15.4 is legacy.  only used by things that got rolled out early.  btle and bt mesh are eating it, and wifi's eating the rest.  
2019-09-03T00:12:52 < Thorn> karlp: what if the cat complains to his big brother https://www.instagram.com/p/B161Qp4l9KN/

2019-09-03T00:15:28 < karlp> the gains are small and getting smaller
2019-09-03T00:15:41 < karlp> there's been wayyyyyyy mor emoney into getting btle lower power because of phones,
2019-09-03T00:15:56 < karlp> 802.15.4 is still "but we already were? but now ... similar?"
2019-09-03T00:16:16 < qyx> but but but 2.4G
2019-09-03T00:16:21 < karlp> they spoke a lot abotu thread, but what's come out of it?
2019-09-03T00:16:39 < karlp> 2.4G what? all theh original 802.15.4 is 2.4G.
2019-09-03T00:16:57 < karlp> adding a subgig phy spec was a desparate attempt to try and regain some niche
2019-09-03T00:18:06 < mawk> for critical applications I wouldn't trust bt
2019-09-03T00:18:15 < mawk> you see critical CVE everyday
2019-09-03T00:18:20 < karlp> why would you not trust bt, but you woudl trust 802.15.4?
2019-09-03T00:18:35 < karlp> you see cves for bt because people are using bt, and people have bt hardware 
2019-09-03T00:19:02 < mawk> it's about design and the number of stages in the bt stack
2019-09-03T00:19:05 < karlp> you _reallllly_ think that all that "secure" 802.15.4 is secure?
2019-09-03T00:19:08  * karlp laughs

2019-09-03T00:24:37 < qyx> what would you trust

2019-09-03T00:29:16 < qyx> ah nice, did you implement the exact algo from the RFC?
2019-09-03T00:29:37 < Thorn> just took the reference implementation
2019-09-03T00:38:37 < catphish> oh my god this is maddening, has anyone ever killed themselves from trying to implement USB?
2019-09-03T00:38:50 < veverak> I suspest a lot of people
2019-09-03T00:39:39 < zyp> haha
2019-09-03T00:39:56 < zyp> catphish, where are you stuck?
2019-09-03T00:40:49 < catphish> my host is echoing back bytes received from my device, i don't know it's doing that, it's an odd distraction, my device isn't recognising completed interrupt in transfers, and overall, my attempt to stream some text is stalling after a few small transfers
2019-09-03T00:41:06 < zyp> karlp, I've yet to see bt mesh in the wild, but I got the house full of zigbee
2019-09-03T00:41:17 < zyp> but I might be behind on the newest toys :p
2019-09-03T00:42:14 < zyp> catphish, echoing? how so?
2019-09-03T00:43:30 < catphish> so, i've implemented a CDC (virtual serial port), it just endlessly streams "ABCDE\n" to the host on its "data in" bulk channel
2019-09-03T00:43:55 < catphish> this works, a few of those strings reach the host, but several other confusing things happen
2019-09-03T00:44:13 < zyp> do you got some shit like a getty running on the host? :p
2019-09-03T00:44:31 < catphish> one is that the host is sending back individual bytes "A" "B" "C" to the data out bulk channel
2019-09-03T00:44:56 < catphish> i'm using linux's cat, it probably shouldn't do this

2019-09-03T00:45:48 < kakimir> hello night pump
2019-09-03T00:46:00 < zyp> side question; why do you bother with CDC ACM?
2019-09-03T00:46:13 < catphish> i just want it to work out of the box
2019-09-03T00:46:29 < zyp> want what to work?
2019-09-03T00:46:50 < catphish> i want my device to show up as a character device in linux
2019-09-03T00:46:55 < catphish> that's all realy
2019-09-03T00:47:20 < catphish> so i can cat it, and receive log text from the device
2019-09-03T00:47:42 < Getty> zyp: i am not running, in best case i am walking, but most often just sitting around <badumtss>
2019-09-03T00:47:55 < zyp> hah :)
2019-09-03T00:48:12 < catphish> the second problem is that i don't think interrupt in transfers are working properly, after an interrupt in transfer occurring, i don't get a success interrupt for it
2019-09-03T00:48:25 < zyp> interrupt?

2019-09-03T00:50:14 < catphish> "interrupt in" transfers ie data sent to the host by the device when the host makes an interrupt endpoint request
2019-09-03T00:50:34 < zyp> so that's an unrelated problem?
2019-09-03T00:50:52 < catphish> unrelated to the echoing problem, yes
2019-09-03T00:51:04 < catphish> the data seems to get sent, but the stm32 doesn't set the flag to say it was successful
2019-09-03T00:51:06 < zyp> do you treat bulk and interrupt differently? I assume the same works for bulk?
2019-09-03T00:51:24 < catphish> yes, the exact same code works for bulk
2019-09-03T00:51:45 < zyp> weird, I don't think they are different from a device perspective
2019-09-03T00:52:01 < zyp> AFAIK the main difference between bulk and interrupt is how the host schedules polling of them
2019-09-03T00:52:13 < catphish> i don't think so either, the type is specified, but the RM says they work the same
2019-09-03T00:52:24 < zyp> (interrupt gets reserved slots, bulk is best effort)
2019-09-03T00:53:17 < catphish> that's my understanding too

2019-09-03T00:55:28 < catphish> hadnt seen any need to do host side programming
2019-09-03T00:55:39 < catphish> but it seems like i might need to, if only for testing
2019-09-03T00:55:41 < zyp> ACM is cool enough to make a device that works with legacy software, but fuck making new stuff with it
2019-09-03T00:56:15 < catphish> the only reason i'm doing ACM is to learn USB and get soemthing working without having to worry about host side programming
2019-09-03T00:56:39 < zyp> plain USB gives you framing and reliability, ACM throws that out by layering a dumb bytestream on top of it
2019-09-03T00:56:47 < catphish> when it works, i will be throwing it away and writing a mass storage device
2019-09-03T00:57:13 < catphish> i want a byte stream though, it's like the most basic test case
2019-09-03T00:57:37 < catphish> at least it would be if it weren't for this interrupt endpoint nonsense
2019-09-03T00:57:42 < catphish> and control, and etc
2019-09-03T00:57:46 < zyp> useful for text output, annoying for protocol parsing
2019-09-03T00:57:57 < catphish> indeed, for now i just want hello world
2019-09-03T00:58:15 < zyp> why not make an easy libusb hello world instead?
2019-09-03T00:58:48 < catphish> well i might have to at this point, but cdc is making too many weird things happen at once

2019-09-03T01:00:15 < karlp> I'm not following latest toys either :)
2019-09-03T01:00:17 < catphish> is this why a million usb serial adapters aren't even CDC?
2019-09-03T01:00:27 < catphish> even though it's literally designed for the purpose
2019-09-03T01:00:41 < zyp> karlp, also the xiaomi shit I'm using for temperature sensors

2019-09-03T01:01:07 < catphish> i wonder if there's an off the shelf libusb frontend i can use to test stuff
2019-09-03T01:01:46 < zyp> ACM is fine, but you're adding extra moving pieces
2019-09-03T01:02:30 < catphish> i'm not trying to :(
2019-09-03T01:02:31 < zyp> also, libusb is super easy, I like using the python wrappers to make direct requests from interactive python
2019-09-03T01:03:34 < catphish> never occurred to me there'd be high level language bindings, if i can ruby-usb that'll be ideal
2019-09-03T01:03:44 < catphish> can convert to C later :)
2019-09-03T01:04:25 < catphish> and of course, i can, lovely
2019-09-03T01:05:21 < zyp> python-libusb is something like «import usb.core» «dev = usb.core.find(idVendor = x, idProduct = y)» then use dev.get_active_configuration() to get endpoint objects, then just ep.read() or ep.write()

2019-09-03T01:07:57 < zyp> isn't this pyusb?
2019-09-03T01:08:04 < zyp> and then the other one is python-libusb1?
2019-09-03T01:08:26 < karlp> instead of "I feel like it should work with cat /dev, even if now I'm pulling in a whole history of linedisciplines and baked/cooked formatting and expections of line buffering and ....."
2019-09-03T01:08:42 < zyp> :)
2019-09-03T01:09:04 < karlp> yeah, your paste looks like pyusb, I've heard good things about pythonlibusb1 too, but *shrugs*
2019-09-03T01:09:04 < zyp> I'm aware of two libusb wrappers for python, and I tend to use a mix of both
2019-09-03T01:09:15 < karlp> I've even used lua-libusb1, works ~same as well too.
2019-09-03T01:09:22 < karlp> fuck writing shit in c for desktop linux
2019-09-03T01:09:52 < zyp> IMO python-libusb1 is nicer but requires more boilerplate to get started
2019-09-03T01:10:11 < karlp> is it just "nicer" because it's more like the libusb api docs?
2019-09-03T01:10:29 < zyp> so I tend to use pyusb for dead simple stuff and python-libusb1 for stuff that benefits from event handling and callbacks
2019-09-03T01:10:47 < karlp> I mean, I went and used the libusb1 version to try out async transfers, and I coulnd't get any extra perf out, despite all the extra boiler plate
2019-09-03T01:10:55 < zyp> https://paste.jvnv.net/view/tFJlT
2019-09-03T01:11:07 < karlp> I have a version of ~most of the gadget0 tests in the libusb1 style somewhere for something I was trying to test.
2019-09-03T01:11:38 < karlp> oh no, it was, "this is a timing thing, pyusb won't be able to do that" "use libusb1 to demonstrate failure, see that it fails just as easily with pyusb too..."
2019-09-03T01:11:59 < fenugrec> sounds familiar
2019-09-03T01:12:31 < karlp> yeah, you were involved :)
2019-09-03T01:12:36 < karlp> I'm not sure there's even a solution yet :)
2019-09-03T01:13:02 < kakimir> https://pr0gramm.com/top/3397390
2019-09-03T01:13:10 < zyp> I think the advantage becomes apparent once you want to have more than one transfer scheduled at the same time
2019-09-03T01:13:21 < zyp> e.g. while waiting for traffic from multiple endpoints
2019-09-03T01:13:30 < karlp> hrm. shit.
2019-09-03T01:13:34 < fenugrec> I'm foggy on the details, was that the buffer corruption one ? fix was simple, no ? just sent BUFCON or whatever properly

2019-09-03T01:49:22 < catphish> my only complaint would be that it was too easy
2019-09-03T01:57:04 < catphish> interrupt transfers work fine with libusb, clearly i was just doing CDC wrong
2019-09-03T01:57:09 < catphish> never mind :)

2019-09-03T02:07:04 < catphish> i just found a pdf, it's pretty poorly written anyway
2019-09-03T02:07:18 < aandrew> ldr r3, =0x40023800
2019-09-03T02:07:24 < aandrew> ldr r3, [r3, #4]
2019-09-03T02:07:31 < aandrew> ubfx r3, r3, #16, #2
2019-09-03T02:07:35 < aandrew> adds r3, #1
2019-09-03T02:07:40 < aandrew> lsls r3, r3, #1
2019-09-03T02:08:00 < aandrew> first two put the contents of address 0x40023804 into R3, right?
2019-09-03T02:08:59 < Thorn> no, the address is @ 0x40023800
2019-09-03T02:09:07 < aandrew> no, #4 is the offset
2019-09-03T02:09:21 < Thorn> or is that the literal syntax
2019-09-03T02:09:24 < aandrew> the literal value 40023800 is put in R3
2019-09-03T02:09:41 < aandrew> then the contents of address@r3+4  put in R3
2019-09-03T02:10:00 < aandrew> oh wait, this thing jumped on me
2019-09-03T02:11:23 < aandrew> wtf
2019-09-03T02:11:27 < aandrew> nevermind that
2019-09-03T02:11:32 < aandrew> ldr r3, =0x40023800
2019-09-03T02:11:37 < aandrew> ldr r1, [r3, #4]
2019-09-03T02:11:43 < aandrew> ubfx r1, r1, #6, #9
2019-09-03T02:11:48 < aandrew> movs r3, #0
2019-09-03T02:11:57 < aandrew> ldr r0, =0x01d7840 (25MHz)
2019-09-03T02:12:05 < aandrew> umull r0, r1, r1, r0
2019-09-03T02:12:17 < aandrew> so r3 has the value 0x40023800
2019-09-03T02:12:30 < aandrew> the *r1* is supposed to have whatever is at the address [r3+4]
2019-09-03T02:12:38 < aandrew> but oone shows *r3* getting that value
2019-09-03T02:12:46 < aandrew> step the first instruction, r3 has 0x40023800
2019-09-03T02:13:01 < aandrew> step the next and *r3* now has 0x2940c619
2019-09-03T02:13:03 < aandrew> wtf
2019-09-03T02:13:27 < aandrew> it's all getting the right values but they're in r3 not r1
2019-09-03T02:13:38 < aandrew> (btw ubfx is a pretty slick instruction)
2019-09-03T02:14:39 < aandrew> then movs r3, #8 changes R6
2019-09-03T02:14:45 < aandrew> I think ozone is on fucking crack

2019-09-03T10:08:11 < Cracki> I am dithering about when to leave. I have some time on a laser cutter and 3d printer scheduled for 3h from now.
2019-09-03T10:10:01 < Cracki> also googling power outlets. I know european/german outlets have no polarity as such, but the french have defined which one is N and which is L
2019-09-03T10:12:57 < Cracki> schuko is reversible and not marked at all but maybe there's code saying "L is left, N is right" or something
2019-09-03T10:17:34 < Cracki> beheaded extension cord for psu shows wires colored such (angled wall plug, tail down), so I'll stick with that
2019-09-03T10:20:40 < qyx> yes, it is L on the left
2019-09-03T10:20:46 < qyx> but afaik this is not mandatory anymore
2019-09-03T10:20:51 < qyx> at least here
2019-09-03T10:28:22 < Cracki> I'll have to find an opportunity to probe all the outlets. I'll beep the extension cords too...

2019-09-03T10:29:38 < sync> yes, but that
2019-09-03T10:29:44 < sync> 'd be illegal now
2019-09-03T10:29:49 < Cracki> what would
2019-09-03T10:29:52 < Cracki> touching lamps?
2019-09-03T10:30:05 < Cracki> or unearthed lamps?
2019-09-03T10:30:12 < dongs>  < Cracki> you feel a hum on your skin when skin contact is very light
2019-09-03T10:30:17 < Cracki> 2-pin is still legal and sold around here
2019-09-03T10:30:20 < dongs> i get this whenever i touch my laptop when i plug it into stuff in taiwan
2019-09-03T10:30:27 < Cracki> awesome
2019-09-03T10:30:40 < sync> yes, but most lamps are now three pinners
2019-09-03T10:30:43 < Cracki> I used to have a laptop with 2-prong wall plug too. it was ass.
2019-09-03T10:30:46 < sync> or at least double isolated
2019-09-03T10:30:54 < dongs> it sorta feels like your finger is flying over the material
2019-09-03T10:31:05 < dongs> the staticky thing makes it slide smoother or something
2019-09-03T10:31:11 < Cracki> tbh I don't know why this lamp's metal frame would have any contact with its wires
2019-09-03T10:31:23 < Cracki> the whole cord goes through the frame
2019-09-03T10:32:03 < dongs> wtf
2019-09-03T10:32:04 < Cracki> yeah feels funny. I'm glad that's all it feels like because it's a gentle warning.
2019-09-03T10:32:09 < dongs> seedstudio shipped my order from this morning
2019-09-03T10:32:20 < Cracki> they must be bored
2019-09-03T10:32:44 < dongs> Ya
2019-09-03T10:34:50 < Cracki> meh time to shower. let's see if that fablab has suitable crimping pliers
2019-09-03T10:39:10 < dongs> me too
2019-09-03T10:39:33 < dongs> 9V batts is about the max i go for tho
2019-09-03T10:39:41 < dongs> that gives a nice jolt
2019-09-03T10:45:32 < Cracki> we have these 4.5v flat things. they do an angry tickle. I didn't dare lick a fresh 9v ever
2019-09-03T10:46:05 < Cracki> I could try one of the empty 9v from the smoke alarms... they drop to zero if you wave a 100k at them

2019-09-03T10:47:52 < Cracki> spring only between terminals, or spring + tongue between them?

2019-09-03T13:56:40 < Thorn> cheap as in cheap or cheap?

2019-09-03T13:58:32 < karlp> Thorn: is the the amoeba shit?
2019-09-03T13:58:36 < dongs> yes
2019-09-03T13:59:36 < Thorn> is there a wi-fi module that does wi-fi? so that I can connect it to a MCU and run lwip there
2019-09-03T13:59:52 < Thorn> no custom dev env / SDK / ardweeno / shit
2019-09-03T14:00:23 < englishman> esp32 and at commands?
2019-09-03T14:04:24 < dongs> thorn, any SDIO wifi module i guess
2019-09-03T14:04:26 < dongs> but it wont be cheap
2019-09-03T14:05:28 < emeryth> esp8266 is literally an sdio wifi chip

2019-09-03T14:14:15 < jadew> I didn't remember the name of a fighter properly so I searched for "jumbo beard fight" and got kimbo slice
2019-09-03T14:17:00 < Cracki> the sdio-wifi bridge thing is particularly explained in "esp12f" and similar derivative hw docs
2019-09-03T14:29:09 < Thorn> can I connect multiple slaves to an SDIO bus (like SPI)?
2019-09-03T14:29:14 < zyp> dongs, how's my shit coming along?
2019-09-03T14:34:14 < karlp> what, you want multiple wifis? what else you gonna get in sdio?

2019-09-03T14:36:56 < Thorn> karlp: eMMC for example
2019-09-03T14:37:36 < karlp> it might be, but I've only seen it on board schematics on differnet sdio channels altogether
2019-09-03T14:38:17 < Thorn> say my host mcu has 2 sdio controllers and I want 3 sdio slaves: a µSD card, an eMMC, and a wi-fi module
2019-09-03T14:39:35 < karlp> I'd say you're doing it wrong already then :)
2019-09-03T14:39:57 < Thorn> what is wrong about it
2019-09-03T14:41:29 < karlp> why both sd and emmc?
2019-09-03T14:41:58 < karlp> use usb for either sd or wifi?
2019-09-03T14:43:56 < Thorn> that's usb host + usb hub + usb sdio controller
2019-09-03T14:44:19 < Thorn> overengineering, the best kind of engineering
2019-09-03T14:44:22 < Cracki> Thorn, would simple SPI be an option for two of those
2019-09-03T14:44:43 < karlp> you said you had 2 sdio controllers? you got them both on usb?
2019-09-03T14:45:01 < Thorn> if I can put the wi-fi on SPI that would be great
2019-09-03T14:45:32 < karlp> they do, if you want to pay more than thorn's monthly wage
2019-09-03T14:45:32 < Cracki> sdio was created to talk to devices plugging into the SD slot that aren't simple sd cards
2019-09-03T14:46:47 < Cracki> see section "ganging cards together" https://en.wikipedia.org/wiki/SD_card#SDIO_cards
2019-09-03T14:47:03 < Cracki> so it might be possible
2019-09-03T14:48:15 < Cracki> even they say it's a bus for multiple devices https://www.sdcard.org/developers/overview/sdio/index.html

2019-09-03T21:13:11 < PaulFertser> Cracki: what CAD are you using?
2019-09-03T21:13:23 < Cracki> inventor
2019-09-03T21:13:41 < Cracki> fusion has better features earlier (or at all) but I want my files local
2019-09-03T21:15:29 < Cracki> fusion has this "timeline" view. it's a direct improvement upon inventor's list of features.

2019-09-03T22:21:44 < catphish> so maybe, when we have a functional democratically elected parlaimentary government again, we'll think about getting it done

2019-09-03T22:22:26 < Steffanx> but im done with it as well. its dominating the news.

2019-09-03T22:36:20 < Cracki> have you "mounted" them (at least given them a letter) or are they simply known to windows as network locations?

2019-09-03T22:53:04 < Cracki> it works on physical disks, partitions, images... all the same
2019-09-03T22:53:14 < Cracki> might come with the tools you need
2019-09-03T22:54:07 < Cracki> if you want to mount it as a physical disk: https://www.osforensics.com/tools/mount-disk-images.html
2019-09-03T22:55:09 < Cracki> no guarantee that it allows to mount files on a network share
2019-09-03T22:55:25 < kakimir> diskpart can add over network
2019-09-03T22:55:31 < Cracki> another option: iscsi with support from your freenas
2019-09-03T22:56:17 < Cracki> newer windows seems capable of mounting its own disk image formats https://docs.microsoft.com/en-us/powershell/module/storage/mount-diskimage?view=win10-ps
2019-09-03T22:56:21 < kakimir> I already did it to use converted .vhd as physical drive only to notice it doesn't even have partition table
2019-09-03T22:56:41 < kakimir> I maybe need to check if toolkit can see that
2019-09-03T22:56:53 < Cracki> try winhex on the file
2019-09-03T22:57:22 < Cracki> I'm not a fan of those shoot-and-forget tools. winhex can look for signatures too.
2019-09-03T22:58:12 < Cracki> it's not good (at all) at editing partition metadata. it has "templates" you can apply to mbr and gpt structures but then you have to calculate values yourself
2019-09-03T22:58:19 < Cracki> it is good at finding things

2019-09-03T23:10:26 < Cracki> you could just buy a huge disk for the image and directly attach it

2019-09-03T23:11:50 < Cracki> what's the trouble, did something fuck file system headers?
2019-09-03T23:12:39 < Cracki> if the partitioning is gone... ntfs stores header and footer and those reference each other so *that* can be recovered. ext prolly does something similar
2019-09-03T23:15:11 < kakimir> iirc first 8GB are not accessable
2019-09-03T23:15:28 < Cracki> mbr is a linked list, so if you can recover/recalculate the mbr, all the rest magically reappear
2019-09-03T23:15:54 < Cracki> readout error from disk? something overwrote the data?
2019-09-03T23:17:11 < Cracki> if it's ntfs, you might be in luck. the header sector is mirrored at the last sector. the allocation table might have a mirror too, can't remember.

2019-09-04T00:40:44 < catphish> (l4 not f4)
2019-09-04T00:40:59 < day> did u design that parallel to usb board?
2019-09-04T00:41:05 < catphish> yes
2019-09-04T00:41:10 < day> nice
2019-09-04T00:41:33 < catphish> better pic of the board https://i.imgur.com/TEDFmct.jpg
2019-09-04T00:42:24 < catphish> it's designed to read / write unusual / proprietary floppy disk formats that can't be read by a PC floppy controller, initially amiga disks
2019-09-04T00:42:51 < day> o0
2019-09-04T00:42:54 < catphish> super simple pcb design :)
2019-09-04T00:43:19 < day> but you dont seem to have alterned the device itself, so wouldnt a custom driver be sufficient for that?
2019-09-04T00:43:25 < day> altered*
2019-09-04T00:43:56 < catphish> the drive is standard, but the controller is custom
2019-09-04T00:44:29 < catphish> PCs (and PC USB floppy drives) have their own controller that can only read PC-formatted disks
2019-09-04T00:44:50 < day> but you are interacting with the drive through its original  parallel interface right?

2019-09-04T00:48:19 < catphish> it's a pretty simple interface really, just a few GPIOs for stepper motor control, and pulses of data
2019-09-04T00:49:15 < catphish> just needs some fancy software and timers to decode the data

2019-09-04T02:49:22 < catphish> dumb question - can i reset a general purpose timer using any of its 4 gpio inputs?
2019-09-04T02:50:08 < catphish> i'm trying to measure the time between pulses on TIM2_CH3 and missing how to set up the reset
2019-09-04T02:51:07 < karlp> hrm, time to reassign pins on this pciex connector again :)
2019-09-04T02:54:15 < catphish> i want ITR2 maybe
2019-09-04T02:58:45 < catphish> oh, i can't that's unfortunate :(
2019-09-04T03:01:28 < catphish> TIM2 is 32 bit though, so i can just subtract the previous value of TIM1->CCR3 each time
2019-09-04T03:03:47 < karlp> what are you trying to reset? have one pin be the trigger for counting, and another to automatically manage resetting it?
2019-09-04T03:07:01 < kakimir> how to end email?
2019-09-04T03:07:09 < kakimir> when I'm eager to hear from them
2019-09-04T03:07:36 < kakimir> when it's seriousness level: getting a job
2019-09-04T03:08:29 < Thorn> "I've got job offers from google, facebook and amazon, so please respond quickly if you want to have a chance at hiring me"
2019-09-04T03:09:00 < catphish> karlp: i just want to count the time between pulses, i'd normally do this by having the same pin assigned to both capture input and timer reset, but unfortunately i designed this board with the input connected to a pin that can't reset the timer
2019-09-04T03:09:20 < catphish> so instead, i will let the timer run free, and just measure the difference between capture values
2019-09-04T03:09:33 < Thorn> kakimir: read this https://www.freecodecamp.org/news/ten-rules-for-negotiating-a-job-offer-ee17cccbdab6/

2019-09-04T04:09:57 < Thorn> so esp-idf is actually using lwip for tcp/ip? at least some good news
2019-09-04T04:15:47 < dongs> englishman: none, isnt ADUC thier mcu line shit
2019-09-04T04:16:24 < dongs> but they always used some garbage cores that nobody knows about
2019-09-04T04:20:07 < catphish> looks like usb-fs is indeed just about fast enough to stream this raw (4Mbps) data :)
2019-09-04T04:21:18 < Thorn> any recommendations on esp32 modules, there are https://www.aliexpress.com/item/32988186010.html and https://www.aliexpress.com/item/4000087125084.html etc.

2019-09-04T04:23:59 < Thorn> WROOM is the original one?
2019-09-04T04:24:02 < dongs> so its all about ESP32 now?
2019-09-04T04:24:06 < dongs> the other ESP is ded?
2019-09-04T04:24:11 < dongs> still same garbage core right?
2019-09-04T04:24:18 < englishman> works with coresight
2019-09-04T04:25:14 < dongs> Xtensa LX6
2019-09-04T04:25:16 < dongs> whats coresight
2019-09-04T04:25:44 < englishman> who cares how garbo the core is when it runs at 240MHz
2019-09-04T04:25:48 < rajkosto> tracing part of cortex cores ?
2019-09-04T04:26:10 < rajkosto> you can get cortex m4 that run way faster englishman

2019-09-04T04:26:26 < englishman> not for $2 in a fcc'd module with bt and wifi
2019-09-04T04:26:43 < rajkosto> its still not ARM architecture right
2019-09-04T04:26:48 < englishman> st's bluetooth only shit with closedsores f0 inside is like $10

2019-09-04T04:32:59 < Thorn> yeah RMII signals going into the WROOOOOOOOOM
2019-09-04T04:33:56 < englishman> An IEEE-802.3-2008-compliant Media Access Controller (MAC) is provided for Ethernet LAN communications.
2019-09-04T04:33:56 < englishman> ESP32 requires an external physical interface device (PHY) to connect to the physical LAN bus (twisted-pair, fiber,
2019-09-04T04:33:56 < englishman> etc.). The PHY is connected to ESP32 through 17 signals of MII or nine signals of RMII. The following features are
2019-09-04T04:33:56 < englishman> supported on the Ethernet MAC (EMAC) interface:
2019-09-04T04:33:56 < englishman> • 10 Mbps and 100 Mbps rates
2019-09-04T04:33:57 < englishman> • Dedicated DMA controller allowing high-speed transfer between the dedicated SRAM and Ethernet MAC
2019-09-04T04:34:05 < Thorn> maybe I should delegate both wi-fi and ethernet to the esp32 in my controller project and let the stm32 run user programs and communicate with slaves

2019-09-04T12:26:26 < PaulFertser> dongs: WSL is kinda "Wine" in reverse, that is, it runs "lunix" programs on windows natively.
2019-09-04T12:26:40 < dongs> PaulFertser: there is literally not a single lunix program I want to run in windows
2019-09-04T12:26:46 < dongs> this is generally the fact with any opensores software
2019-09-04T12:27:03 < jly> that reminds me of my 20 minutes of running a hackintosh
2019-09-04T12:27:05 < dongs> like, lunix dorks spend years dreaming how to run program X that exists and works on windows
2019-09-04T12:27:10 < dongs> but the reverse is .... ???
2019-09-04T12:27:23 < PaulFertser> And WSL2 seems to be a para-virtualised Linux kernel running on Windows.
2019-09-04T12:27:27 < dongs> there are no windows users who cry all day hoping to run some lunix shitware

2019-09-04T13:15:08 < salcedo> nah
2019-09-04T13:15:40 < salcedo> those vespa mandarinia hang out in low areas  and almost nonexistant at high altitudes
2019-09-04T13:17:07 < salcedo> your oxygen level theory is inversely proportional to what the hornets actually do

2019-09-04T13:18:43 < karlp> so, those big wasps are at low altitudes? with more o2?.... 
2019-09-04T13:19:39 < salcedo> "They prefer to live in low mountains and forests, while almost completely avoiding plains and high-altitude climates. V. mandarinia creates nests by digging, co-opting pre-existing tunnels dug by rodents, or occupying spaces near rotted pine roots."
2019-09-04T13:21:39 < salcedo> Haohmaru: there's no need to go to those places to see your wasp friends though.
2019-09-04T13:21:52 < salcedo> they'll come to us.
2019-09-04T13:22:44 < salcedo> i'm already seeing larger insects here
2019-09-04T13:23:10 < salcedo> yea
2019-09-04T13:23:48 < salcedo> rapid climate change + global JIT food delivery = insects from other countries that previously would mostly die off here are able to survive here now.
2019-09-04T13:23:50 < day> i cant say im seeing bigger insects here. the biggest spider type here is sizeable, but it has always been around
2019-09-04T13:23:56 < salcedo> so we're going to start seeing moar bigger
2019-09-04T13:25:33 < day> nice
2019-09-04T13:25:38 < salcedo> or avocados
2019-09-04T13:25:54 < day> how far north are you?
2019-09-04T13:26:16 < salcedo> the interesting thing about insects being introduced rapidly into areas where they never existed before is that they disrupt the local ecosystems in ways we don't fully understand.
2019-09-04T13:26:49 < salcedo> yea. it even applies to vegetation
2019-09-04T13:26:58 < salcedo> what we do know is
2019-09-04T13:27:12 < salcedo> we start seeing dyoffs of shit that affect our economies
2019-09-04T13:27:25 < salcedo> and you know what the typical solution is?
2019-09-04T13:27:26 < salcedo> plastic
2019-09-04T13:27:33 < salcedo> just throw some plastic at the problem, that'll fix it.
2019-09-04T13:28:50 < day> we have incinerator trucks with giant vacuum suckers here to deal with certain caterpillars :D
2019-09-04T13:30:16 < salcedo> here in ohio, they fly planes around that drop quadrillions of tiny plastic slivers into the air
2019-09-04T13:30:46 < salcedo> yep
2019-09-04T13:30:52 < salcedo> because plastic solves all problems in 'murica
2019-09-04T13:32:16 < salcedo> nah don't do that yet
2019-09-04T13:32:39 < salcedo> we're supposedly using "organic" flakes now... since about 3 years ago
2019-09-04T13:32:50 < salcedo> they biodegrade now
2019-09-04T13:33:42 < salcedo> "SPLAT GM-O is a relatively new product that has become an alternative to the traditionally used pheromone impregnated plastic flakes.

2019-09-04T13:34:04 < jly> full take care do everything 
2019-09-04T13:34:37 < salcedo> see Haohmaru ? we crop dust ourselves with plastic flakes
2019-09-04T13:34:59 < salcedo> so now that you know that's going on. imagine what kinds of other shit is going on too?
2019-09-04T13:36:09 < salcedo> crop dusting the forests with pheromone impregnated plastic flakes in order to control population (of gypsy moths) by disrupting their mating...

2019-09-04T17:36:08 < tctw> it is more likely that you'll get help from somebody if you can explain the issues you're facing / ask specific questions that can be answered.

2019-09-04T18:47:58 < Cracki> the c# tutorials i'm watching rn do a 4-function calculator that "parses" expressions. the dude hasn't heard of tokenization. if he did, hand-rolled topdown parsing would be trivial to write.

2019-09-04T18:49:47 < karlp> I've some of that beningo other advice, and some of it is fine, reasonable fundamental stuff, but fuckme, that strstr json parsing got on my nerves
2019-09-04T18:50:15 < karlp> Thorn: oh yeah, the quality of http server shit I've seen for esp1488 and friends is...... special.
2019-09-04T18:50:22 < Thorn> bootcamp graduates. juniors who have been exposed to programming for the first time 3 months ago. "we're Software Engineers but we don't need no stinking engineering approach!"
2019-09-04T18:52:16 < Cracki> software engineering is actually a craft but there are no trade associations that I know of
2019-09-04T18:52:30 < Cracki> nothing that guards the reputation of the title
2019-09-04T18:53:24 < Cracki> nvm, software developer (system integration or apps development) are vocations with training around here
2019-09-04T18:53:43 < Cracki> still, you don't get that with 3 months of bootcamp, but with 3 years of school and training on the job
2019-09-04T19:08:01 < zyp> I mean, I could totally make a hack that just looks for the presence of a string in a packet to determine commands, but I wouldn't call that json parsing
2019-09-04T19:09:39 < zyp> on the other hand, it'd be pretty easy to make a super dumb json parser that just extracts a single key from a json document
2019-09-04T19:12:47 < englishman> yeah
2019-09-04T19:12:53 < englishman> strstr

2019-09-04T19:14:02 < zyp> no, I mean, you could just traverse the json tree recursively skipping every element until you're at the path you're looking for and then return that
2019-09-04T19:14:17 < Cracki> right, that's probably what many embedded ones do
2019-09-04T19:14:37 < Cracki> the other way would be to parse the tree properly and call visitors/handlers for every element
2019-09-04T19:14:39 < zyp> that way you don't have to mess around with memory allocation shit to hold a parsed json message
2019-09-04T19:14:48 < zyp> yeah
2019-09-04T19:15:15 < Cracki> depends on the situation :P
2019-09-04T19:15:26 < zyp> I mean, it's the same idea, just with nop-visitors
2019-09-04T19:16:04 < englishman> sounds complicated and with no benefits over using strstr
2019-09-04T19:16:10 < Cracki> smart text editors don't load the whole file at once either. they scan it once, noting the beginning of every line, and possibly even condensing that if it's too many millions of lines
2019-09-04T19:16:25 < Cracki> that's how you can view 100 GB log files
2019-09-04T19:17:10 < Cracki> you have trees elsewhere too. in wav/riff files, mp4/mov, mkv, ...
2019-09-04T19:17:26 < zyp> englishman, well
2019-09-04T19:17:42 < Cracki> looking up a chunk means skipping through the "directory lists", same thing
2019-09-04T19:17:47 < zyp> the strstr approach assumes that the search string would not appear in any other sense than the one you're expecting
2019-09-04T19:18:04 < Cracki> that strstr looks like it looks for the presence of particular VALUES
2019-09-04T19:18:10 < zyp> whereas extracting a key makes no assumptions
2019-09-04T19:18:11 < Cracki> I didn't see that it looked for keys
2019-09-04T19:18:16 < zyp> yes
2019-09-04T19:18:41 < zyp> if you have a command enum like that, it might work out well
2019-09-04T19:18:41 < Cracki> kinda dumb, you can't send any numbers or arbitrary strings, just uniquely tagged "enums"
2019-09-04T19:18:51 < englishman> well if you didn't want to turn a led on then why did you write LED_ON
2019-09-04T19:18:53 < zyp> but if you have numeric command codes, good luck
2019-09-04T19:19:06 < Cracki> if that's so, just send the strings as a list without all the json?
2019-09-04T19:19:25 < zyp> yeah
2019-09-04T19:19:26 < Cracki> using strstr is debatable, but what they do with it is just fail
2019-09-04T19:20:07 < zyp> I think what they do is reasonable enough, they just make too much bullshit out of it
2019-09-04T19:20:25  * karlp unsubscribed with prejudice
2019-09-04T19:20:31 < englishman> you have to strstr for the whole key/value pair and check for every combo
2019-09-04T19:20:48 < zyp> that's not gonna work

2019-09-04T19:20:57 < Cracki> now I have to figure out how to glue this bunch of plexiglass panels into a box arrangement, while keeping all the edges clean, and without it slipping away all the time or smearing glue where it doesn't belong. I'm informed enough to use sticky tape to hold it together temporarily
2019-09-04T19:21:24 < zyp> I mean, if you make the whole key/value pair your searchstring, you add assumptions about whitespacing
2019-09-04T19:21:35 < zyp> that's a lot worse
2019-09-04T19:21:44 < Cracki> yuck whitespace
2019-09-04T19:22:09 < zyp> json allows whitespace, parsing json means ignoring whitespace differences
2019-09-04T19:22:26 < Cracki> "just" remove all whitespace before parsing, like old fortran did
2019-09-04T19:22:29 < Cracki> nothing can go wrong
2019-09-04T19:23:09 < zyp> how do you distinguish between whitespace in strings and whitespace between tokens?
2019-09-04T19:23:14 < Cracki> exactly
2019-09-04T19:23:57 < salcedo> there's no need to
2019-09-04T19:23:59 < Cracki> and fortran had syntax where if you just remove whitespace, it could glue together words, and that sometimes produced a proper "keyword" and sometimes an identifier, and if you made a typo... you were fucked
2019-09-04T19:24:26 < Cracki> one could strstr for each string separately and then look for what's between (just whitespace or not)
2019-09-04T19:24:33 < Cracki> whitespace and :
2019-09-04T19:24:59 < Cracki> but then you have an ini/conf basically, no tree structure

2019-09-04T19:56:03 < Cracki> I could grep my logs and guess but cba

2019-09-05T11:12:09 < Cracki> ah. if you don't have a scope, at least click yourself one of those fx2 based cheap logic analyzers.
2019-09-05T11:12:26 < Cracki> and a multimeter too :P
2019-09-05T11:12:43 < ThatDamnRanga> LOL. I have a meter. Just have no idea where my ancient 10MHz CRT scope is
2019-09-05T11:13:11 < ThatDamnRanga> Rigol is on the list... but this project has required enough of an outlay to strain my finances already
2019-09-05T11:14:11 < Cracki> with a meter you can already debug if the f4 is even touching the bus or not
2019-09-05T11:15:00 < ThatDamnRanga> I see SCL clocking, I don't see much happening on SDA, but... the update frequency of the meter is only 1hz
2019-09-05T11:15:14 < Cracki> does it have a bar graph
2019-09-05T11:15:32 < Cracki> send 0101010101 and hope that it shows you 3.3V * 0.5
2019-09-05T11:15:42 < ThatDamnRanga> Bahaha. Mate. It's a basic multimeter. 
2019-09-05T11:16:05 < ThatDamnRanga> It was purchased for work on mains circuits.
2019-09-05T11:16:11 < Cracki> ¯\_(ツ)_/¯
2019-09-05T11:16:19 < Cracki> still, try the 01010101
2019-09-05T11:16:29 < Cracki> unless you get a bus error already
2019-09-05T11:16:39 < ThatDamnRanga> will give it a crack shortly, I've elected to distract myself to avoid stabbing my eyes out :P
2019-09-05T11:16:42 < Cracki> that is, i2c bus
2019-09-05T11:17:02 < Cracki> mbed + f4, there must be working examples
2019-09-05T11:17:17 < Cracki> discoboard I assume?
2019-09-05T11:17:41 < ThatDamnRanga> nucleo446re
2019-09-05T11:18:03 < ThatDamnRanga> And the working examples all use i2c1, which is unavailable because I'm using the canbus modules
2019-09-05T11:19:44 < Cracki> https://os.mbed.com/forum/mbed/topic/4808/
2019-09-05T11:19:55 < Cracki> that's why I say verify using a known example
2019-09-05T11:20:03 < Cracki> without canbus or anything else
2019-09-05T11:20:09 < Cracki> break it down
2019-09-05T11:21:55 < ThatDamnRanga> Yep. Looking through that article all looks good. I was already using 0xA0 because datasheet :P
2019-09-05T11:22:18 < ThatDamnRanga> I'll give it another round shortly. and might bite the bullet on that scope

2019-09-05T13:10:59 < ThatDamnRanga> Can confirm I definitely don't. It's a breadboard, after having had magic smoke issues with a custom board (but not on the EEPROM)
2019-09-05T13:11:42 < ThatDamnRanga> Because I can see the circuit without glasses?
2019-09-05T13:11:57 < ThatDamnRanga> and yes. Trace resistances are 2.16Kohm for SCL and 2.15Kohm for SDA
2019-09-05T13:14:20 < ThatDamnRanga> 10k with power off
2019-09-05T13:16:53 < ThatDamnRanga> Circuit has literally been reduced to its most basic form. One eeprom, one nucleo, two resistors, a breadboard and a buncha jumpers
2019-09-05T13:17:55 < karlp> so examples work then right?
2019-09-05T13:18:27 < ThatDamnRanga> negative
2019-09-05T13:22:24 < ThatDamnRanga> Meh. I'll sleep on it. I'm not gonna get far without waveforms
2019-09-05T13:22:47 < dongs> try making gpio OD and manually clock out stuff on scl/sda to unstick your slaves
2019-09-05T13:23:07 < dongs> if your code is fucked and you power shit up and it tries to send stuff and hangs the slave, then nothing will work after that even if you reset the board
2019-09-05T13:23:15 < dongs> you are doing this with a proper debugger right
2019-09-05T13:23:22 < dongs> or just upload and pray
2019-09-05T13:23:23 < ThatDamnRanga> *dies laughing*
2019-09-05T13:23:34 < ThatDamnRanga> see above. mbed. 'proper debugger' is not a thing in that land

2019-09-05T13:25:00 < PaulFertser> ThatDamnRanga: actually, mbed bootloader includes CMSIS-DAP/DAPLink proper debugger functionality.
2019-09-05T13:25:27 < PaulFertser> And of course nucleo board comes with on-board stlink which is a proper debugger too.
2019-09-05T13:25:54 < ThatDamnRanga> PaulFertser, you're correct. But they support meaningful debugging on like 1-2 of the nucleo boards
2019-09-05T13:26:12 < PaulFertser> ThatDamnRanga: if you like GUIs then you can use GNU MCU Eclipse with proper debugging for any board.
2019-09-05T13:26:13 < ThatDamnRanga> anything else is battling through vscode, which after testing..... doesn't exactly work properly either

2019-09-05T13:43:00 < zyp> anybody need 100pcs STM32L052R8T6? ordered wrong and got the qfp64 instead of qfp48 by accident
2019-09-05T13:45:29 < Orson> Hello! Anyone here used SWO trace with F103 chips? I got a small project I wanted to do bare metal style, but I ran into this issue. I've programmed the registers as per the Ref. man, but my logic analyzer shows zero activity on the PB3 pin. I then switched to a nucleo board and tried one of the examples from Exlipse ARM MCU package which apparently should print stuff to the trace, but there is zero activity on the pin.
2019-09-05T13:46:19 < Orson> It goes as an (O)utput pin in the docs, so I didn't try to tie it anywhere and just looking on it with a saleae analyzer.
2019-09-05T13:46:48 < Orson> Maybe someone who has successfully used SWO can share some piece of the project as a starting point for me?
2019-09-05T13:46:54 < Orson> Thanks.
2019-09-05T13:48:21 < karlp> you don't do anything at all in your code.
2019-09-05T13:48:34 < karlp> you just tell your debugger that's collecting the trace to configure it.
2019-09-05T13:48:41 < karlp> or via gdb scripting.
2019-09-05T13:48:57 < karlp> in your code you just write to the traceports.
2019-09-05T13:49:49 < karlp> eg, targetttign stimulus 0 for printf: https://github.com/libopencm3/libopencm3/blob/master/tests/shared/trace_stdio.c
2019-09-05T13:53:54 < srk> orbuculum has some example gdb scripts
2019-09-05T13:53:57 < dongs> how do i find exact model of STM32 thats connected to SWD
2019-09-05T13:54:51 < Orson> The thing is, I haven't investigated if the st-link and the nucleo I have have the SWO pin connected even. I wanted to see if there is any activity at all because at first I had a natural reason to suspect my own setup code. But now when I tried one of the premades for the nucleo board I'm beginning to suspect that I somehow misunderstand this whole SWO trace thing
2019-09-05T13:55:22 < dongs> >  Anyone here used SWO trace with F103 chips? I
2019-09-05T13:55:24 < dongs> yeah, always
2019-09-05T13:55:30 < dongs> works fine. but i use a proper debugger (jlink)

2019-09-05T14:01:54 < PaulFertser> Orson: nucleo is able to capture SWO output, but you need to check the manual to see if it's connected by default. IIRC, the solder bridge is off so by default you receive SWO from the external target connector, not from the target mcu.
2019-09-05T14:02:13 < Orson> I'm using F103
2019-09-05T14:02:47 < dongs> PaulFertser: how do i find out which STM32 i have connected?? i thought there was a device ID or something
2019-09-05T14:03:01 < zyp> there is
2019-09-05T14:03:03 < dongs> where is it
2019-09-05T14:03:10 < zyp> IIRC DBGMCU block
2019-09-05T14:03:12 < dongs> i see flash size register, i thought it was in that category
2019-09-05T14:03:14 < dongs> oh
2019-09-05T14:03:16 < zyp> next to UID
2019-09-05T14:03:29 < dongs> DBGMCU_IDCODE
2019-09-05T14:03:29 < dongs> ah
2019-09-05T14:05:39 < karlp> PaulFertser: my copy of the nucleo64 manual doesn't ahve any bolding for it being on/off by default. 
2019-09-05T14:05:44 < karlp> Orson: is SB15 on or off?
2019-09-05T14:05:48 < dongs> 0x20036410 and flash_size is 0x80 is 128k so its F103RC
2019-09-05T14:06:58 < karlp> I've gotta expect that to be on by default.
2019-09-05T14:07:00 < PaulFertser> 410 is medium density f1, yes.
2019-09-05T14:07:19 < ThatDamnRanga> my SB16 is on
2019-09-05T14:07:24 < ThatDamnRanga> err... whoops
2019-09-05T14:07:35 < ThatDamnRanga> SB15 is also on, on the 446RE
2019-09-05T14:07:41 < Orson> Yeah, SB15 is bridged, and it looks like the correct line
2019-09-05T14:07:56 < karlp> and you ahve a nucleo, not some china psueod stlink?
2019-09-05T14:08:01 < karlp> then your hardware is fine
2019-09-05T14:08:07 < Orson> Shouldn't I be just able to see the trace in the ST-Link utility?
2019-09-05T14:08:12 < karlp> yes.
2019-09-05T14:08:21 < ThatDamnRanga> karlp, you're talking to him or me?
2019-09-05T14:08:23 < dongs> did you acutally enable trace
2019-09-05T14:08:38 < karlp> I have no real care about yoru i2c on mbed sorry ranga
2019-09-05T14:08:42 < Orson> Hm how do I know if the nucleo is genuine?
2019-09-05T14:08:53 < dongs> um, pretty sure nobody caresa bout cloning those
2019-09-05T14:08:59 < ThatDamnRanga> karlp, that's so blunt I'm surprised you're not Finnish
2019-09-05T14:10:08 < PaulFertser> ThatDamnRanga: why do not you try libopencm3 instead of mbed? And use debugging facilities that you do have?
2019-09-05T14:10:25 < dongs> does libopencm3 even support F446
2019-09-05T14:10:36 < ThatDamnRanga> PaulFertser, partly because it'd require refactoring nearly a megabyte of code :P
2019-09-05T14:10:38 < dongs> im gonna guess it doesnt support more htan halfe of the periperhasl on it
2019-09-05T14:11:09 < PaulFertser> ThatDamnRanga: still you can use debugging without online-IDE or something like that, you can build it all locally with GCC-based toolchain, right?
2019-09-05T14:11:09 < ThatDamnRanga> Yes, yes, stupid me for writing most of the application before getting the periphs working, I know
2019-09-05T14:11:24 < ThatDamnRanga> PaulFertser, bugger the online IDE lol. I'm using Mbed Studio
2019-09-05T14:11:44 < ThatDamnRanga> I'm not chucking my code in some website and hoping it doesn't get sold to the highest bidder
2019-09-05T14:11:45 < PaulFertser> ThatDamnRanga: debugging targets doesn't depend on specific board...
2019-09-05T14:12:31 < PaulFertser> ThatDamnRanga: if your studio generates a regular ELF you can debug it with any IDE you like. Even visualstudio (with visualgdb or whatever it's called).
2019-09-05T14:13:08 < ThatDamnRanga> PaulFertser, Yeah, the issue usually lies around getting the IDE to accept said ELF file without demanding an entire project
2019-09-05T14:13:21 < ThatDamnRanga> I'm about to attempt an approach utilising sw4
2019-09-05T14:13:27 < dongs> use a standalone debugger like ozone then.. oh, wait.. you are using brokebitch st-link
2019-09-05T14:13:38 < PaulFertser> ThatDamnRanga: I'm just using plain GDB + OpenOCD, works with any ELF.
2019-09-05T14:13:48 < dongs> yeah but LOL at using "plain gdb"

2019-09-05T14:16:28 < PaulFertser> dongs: indeed, though sometimes plain gdb skills help me to not waste time when debugging remotely.
2019-09-05T14:18:13 < PaulFertser> dongs: I have a feeling I spend more time reading datasheets and thinking rather than actual interaction with the debugger where an IDE could help. I've tried Keil in action, and Eclipse, it didn't feel like a real boost in productivity.
2019-09-05T14:19:17 < ThatDamnRanga> karlp, my trust for automagical code creators is uh... minimal... I'm used to register-bashing from scratch. my time with AVRs predates arduino. But these ARM thingys are a bit more complex

2019-09-05T17:39:24 < Ecco> I'm reading the datasheet of an LCD controller, and it says "Digital power (VDD1) : 1.8V ~ 3.3V" and "Analog Power (VDD2) : 2.7V ~ 3.3V"
2019-09-05T17:39:50 < Ecco> So I'm wondering : why two different power inputs?

2019-09-05T20:26:48 < nuxil_> im using hal and have a question. using. __HAL_RCC_GPIOA_CLK_ENABLE(); will enable the gpio clock. but is there a way to see if its alreay set? or do need to mess around reading registers for that?
2019-09-05T20:26:56 < Thorn> karlp: is that a stm32 used in a pci-e interface?
2019-09-05T20:27:13 < jpa-> nuxil_: why do you want to know if it is already enabled?

2019-09-05T20:29:06 < Mangy_Dog> Fucking hell this had really done my head in... Trying to figure out a strange bug where a value was being placed into a varible i had from nowhere... No idea at all, i was following my code and simply couldnt find where this value came from... But then i change the variable name from x1 to something else... and low and behold the bugs gone... I can only assume x1 and y1 are vars being used 
2019-09-05T20:29:06 < Mangy_Dog> somewhere in a library or in the core system... But no idea why the compiler didnt throw a wobbly at that. Whats really strange it should have said the var was already used. But nothing came up. Its only when i made the var global that i started getting strange assignment errors and it started to twig that it might have been used in a core library... anyway changing worked and 3 hours wasted
2019-09-05T20:29:07 < nuxil_> jpa-, well. im writeing my own code for a 4x4 matrix keypad. consider this code. http://paste.debian.net/1098946/ in Matrix_KeyPad_Init.. you see i call the enable gpio clock functions alot. 
2019-09-05T20:29:53 < nuxil_> woundering its ok to do so, "it works tho" but was woundering if i should see if the clock is running already so i dont need to recall it.
2019-09-05T20:30:03 < jpa-> nah, it just sets a bit in register
2019-09-05T20:30:20 < jpa-> no harm in calling it again - though you could just enable all four to start with
2019-09-05T20:30:40 < jpa-> it's not like you save any detectable amount of power by leaving one off
2019-09-05T20:30:52 < nuxil_> alright,
2019-09-05T20:32:25 < salcedo> nuxil_: why Hal_Delay(1) after reading every pin?

2019-09-05T20:47:42 < PaulFertser> Mangy_Dog: probably you have that variable in another object file. Is that a global? How is it defined and declared?

2019-09-05T20:54:35 < Mangy_Dog> paul thats what was happeniing
2019-09-05T20:54:41 < Mangy_Dog> but it wasnt a var i declared
2019-09-05T20:54:49 < Mangy_Dog> there was a pre exsisting var somewhere
2019-09-05T20:55:01 < Mangy_Dog> maybe in a library im using or in the duino core 
2019-09-05T20:55:03 < Mangy_Dog> who knows

2019-09-05T21:04:34 < Mangy_Dog> i prefer c++ and what i know ill keep my serial.write/print/println and not have to learn some strange new hal methods
2019-09-05T21:05:24 < nuxil_> c++ is more strange :p
2019-09-05T21:07:53 < Mangy_Dog> :p
2019-09-05T21:09:27 < nuxil_> my setup is simple. i installed that cubemx thingy. i use it to create a Makefile template including stuff like hal. and the rest of the tool chain is just my fav editor and a cmd to run make with gcc.  
2019-09-05T21:09:47 < nuxil_> basically just followed this guide to install the gcc tools. https://www.jann.cc/2013/10/10/embedded_development_with_open_source_tools_on_windows.html

2019-09-05T21:12:53 < PaulFertser> Mangy_Dog: it can't be a compiler warning because it can only be a linker warning, add this to your LDFLAGS: -Wl,--warn-common -Wl,--fatal-warnings

2019-09-05T21:13:50 < Mangy_Dog> because my eclipse setup just doesnt want to use my stlink to program with

2019-09-06T00:39:07 < Cracki> Mangy_Dog, segger ozone
2019-09-06T00:39:39 < Cracki> or eclipse mcu stuff (truestudio/cubeide)
2019-09-06T00:40:08 < Cracki> any reason you subject yourself to needless pain?
2019-09-06T00:42:14 < Steffanx> Good good kakimir  
2019-09-06T00:42:29 < kakimir> it doesn't want to boot
2019-09-06T00:42:37 < kakimir> sweet
2019-09-06T00:42:40 < Steffanx> Awh
2019-09-06T00:42:45 < Steffanx> What did you break?
2019-09-06T00:42:59 < kakimir> it just gets confused if I add disks
2019-09-06T00:43:09 < kakimir> it hangs to bootloader
2019-09-06T00:44:09 < kakimir> oh I see freenas screen now
2019-09-06T00:44:29 < kakimir> I had to connect monitor
2019-09-06T00:46:45 < Steffanx> Haha
2019-09-06T00:46:53 < kakimir> why it boots forever after adding disks?
2019-09-06T00:47:02 < Mangy_Dog> going to try ozone
2019-09-06T00:47:33 < kakimir> Steffanx: since I said it doesn't want to boot now it's at "kernel start"
2019-09-06T00:48:37 < kakimir> it's totally stoned

2019-09-06T00:53:43 < kakimir> my first alert
2019-09-06T00:53:47 < kakimir> someone sold me shit
2019-09-06T00:55:04 < kakimir> no.. that was 9PM
2019-09-06T00:55:11 < kakimir> hmm
2019-09-06T00:55:12 < Steffanx> Hm
2019-09-06T00:55:15 < Steffanx> Lol
2019-09-06T00:55:17 < kakimir> hmm
2019-09-06T00:55:28 < kakimir> I just installed them drives
2019-09-06T00:55:55 < Steffanx> But it complains about your boot pool
2019-09-06T00:56:06 < kakimir> why won't it tell shit
2019-09-06T00:56:10 < kakimir> what is the problem
2019-09-06T00:56:35 < Steffanx> Somewhere it shows a tiny bit more info

2019-09-06T00:56:43 < Laurenceb_> this is now a designated Brock Turner appreciation board
2019-09-06T00:56:49 < Steffanx> Otherwise you can go commandline
2019-09-06T00:59:25 < Mangy_Dog> so other than ozone as that makes my computer catch fire for some reason
2019-09-06T00:59:35 < Cracki> use keil
2019-09-06T00:59:43 < Cracki> use cubeide
2019-09-06T00:59:47 < Mangy_Dog> other debugger programs so i can see memory use contents and useage amount
2019-09-06T00:59:49 < Cracki> use watever
2019-09-06T01:00:01 < Steffanx> Ozone sets your windows scheduler tick to 1ms. 
2019-09-06T01:00:10 < Steffanx> Good fun.
2019-09-06T01:00:45 < Steffanx> Which also affects other apps
2019-09-06T01:01:03 < Mangy_Dog> D:
2019-09-06T01:01:14 < Mangy_Dog> well it simply blue screene dmy computer
2019-09-06T01:01:17 < Mangy_Dog> sooooooo not usign it :p
2019-09-06T01:01:52 < Steffanx> Do you even have a jlink?
2019-09-06T01:02:51 < Mangy_Dog> na stlink in swd mode
2019-09-06T01:03:05 < Steffanx> Today while I was working on some usb mass storage bootloader thingy I also had jlink trouble.
2019-09-06T01:03:18 < Cracki> stlink china clone, or on some discoboard? discos and nucleos can be turned into jlink OB
2019-09-06T01:03:31 < Mangy_Dog> heh the chinese clone
2019-09-06T01:03:39 < Steffanx> For some reason it stop working properly. Until I plugged the device (the one I was doing the code for) into another pc
2019-09-06T01:03:43 < Cracki> it might work on those as well, havn't tried
2019-09-06T01:03:56 < Mangy_Dog> theyre usually pretty good but my wireing is for swd only
2019-09-06T01:04:00 < Mangy_Dog> on my project
2019-09-06T01:04:08 < Steffanx> For some reason the usb device messed with the jlink (or entire windows usb stack)
2019-09-06T01:04:15 < Mangy_Dog> fun
2019-09-06T01:04:16 < Cracki> if you have a china clone, cut one 5v pin and hook it up to the swo pin
2019-09-06T01:04:31 < Cracki> the firmware already spports it, but the pin is unconnected
2019-09-06T01:05:20 < Cracki> some board layouts let you cut the upper 5v pin after the via, so it's free and the lower one still has 5v
2019-09-06T01:05:35 < Cracki> some don't, so you get to lose 5v completely
2019-09-06T01:05:40 < Mangy_Dog> the projects already powered so i dont use teh 5v
2019-09-06T01:06:06 < Cracki> I find the 3.3v convenient sometimes
2019-09-06T01:06:15 < Mangy_Dog> sure if you need to power the mcu
2019-09-06T01:07:10 < Mangy_Dog> ok so cube ide is an eclipse program
2019-09-06T01:07:17 < Mangy_Dog> branch
2019-09-06T01:07:57 < Cracki> everyone uses eclipse. truestudio/cubeide, whatever nxp/freescab calls it, ...
2019-09-06T01:08:10 < Cracki> all the work has been done, they just have to brand it
2019-09-06T01:08:38 < Mangy_Dog> so how do i find the memory viewing tools of this then?
2019-09-06T01:08:41 < Mangy_Dog> cubeide
2019-09-06T01:09:04 < Cracki> you set up your project
2019-09-06T01:09:17 < Cracki> you "debug" it, not launch/run it
2019-09-06T01:09:31 < Mangy_Dog> isnt there just a tool i can load up? i really dont want to transfer my project over to this
2019-09-06T01:09:39 < Cracki> then it switches into the debug perspective and hopefully already opens some panels for registers, memory, etc
2019-09-06T01:09:45 < Mangy_Dog> :/ i dont want to debug i need to see the system utilisation
2019-09-06T01:09:50 < Cracki> that would have been ozone
2019-09-06T01:09:57 < Cracki> "utilization"?
2019-09-06T01:10:14 < Mangy_Dog> IE the memory mapping and how much memory is being used at run time
2019-09-06T01:10:24 < Cracki> is an rtos involved
2019-09-06T01:10:30 < Mangy_Dog> freertos
2019-09-06T01:10:41 < Mangy_Dog> i think im hitting a memory cap and i need to see for sure
2019-09-06T01:10:41 < Cracki> you ask the impossible
2019-09-06T01:10:45 < Cracki> use a proper ide
2019-09-06T01:10:49 < Cracki> there are no shortcuts
2019-09-06T01:10:57 < Mangy_Dog> ...
2019-09-06T01:11:05 < Cracki> freertos has apis to tell you these things :P
2019-09-06T01:11:15 < Mangy_Dog> im not asking the impossible... being able to view the memory status of an mcu is pretty standard
2019-09-06T01:11:29 < Cracki> stlink utility has a BASIC debugger
2019-09-06T01:11:32 < Mangy_Dog> or at least is usually
2019-09-06T01:11:36 < Cracki> shows registers, stack ptr among them
2019-09-06T01:11:39 < Mangy_Dog> actually the stlink util isnt showing anything at all
2019-09-06T01:11:42 < Cracki> you can poke all the memory
2019-09-06T01:11:53 < Cracki> you're not holding it right
2019-09-06T01:12:34 < Mangy_Dog> and for your information... I am using a propper ide. If cubeide is a propper one so is the flavour of eclipse im already using and spend months setting up
2019-09-06T01:12:57 < Cracki> proper meaning some company puts _some_ effort into supporting it
2019-09-06T01:13:20 < Cracki> truestudio can show you freertos stats. they probably didn't invent that, so you can have it in vanilla eclipse
2019-09-06T01:13:42 < Mangy_Dog> if you could tell me the plugin ill install it
2019-09-06T01:13:49 < Cracki> you just gotta track it down. I have no idea how eclipse works, if it has an "addon manager" or whatever
2019-09-06T01:13:56 < Mangy_Dog> it does
2019-09-06T01:14:02 < Mangy_Dog> but i need a name
2019-09-06T01:14:26 < Cracki> you need a google https://mcuoneclipse.com/2017/03/18/better-freertos-debugging-in-eclipse/
2019-09-06T01:15:02 < Cracki> cubeide has this too so it either works with stm32 right away or there's some recipe out there to make it work
2019-09-06T01:15:49 < Cracki> brb dicking around

2019-09-06T01:30:23 < Mangy_Dog> hmm clearny missing something

2019-09-06T01:30:41 < Mangy_Dog> isnt there a connect device promt?
2019-09-06T01:30:47 < Cracki> read teh post?
2019-09-06T01:30:55 < Cracki> you have to run it under the debugger
2019-09-06T01:31:00 < Mangy_Dog> yeah it doesnt mention it
2019-09-06T01:31:02 < Cracki> it's not for simply fucking around
2019-09-06T01:31:10 < Cracki> they assume that you don't do your own thing

2019-09-06T01:32:57 < cracki__> obviously
2019-09-06T01:33:12 < cracki__> because they assume that you run/debug things inside eclipse that you built inside it
2019-09-06T01:33:22 < cracki__> it's an ide, not a mind reader
2019-09-06T01:33:28 < Mangy_Dog> Then what do i need to install then>?
2019-09-06T01:33:39 < Mangy_Dog> i thought the plugin i was installing was the debugger

2019-09-06T01:34:28 < cracki__> you do have eclipse for mcu set up so you can build your code inside it and have it use the stink to upload to target and run it?
2019-09-06T01:34:47 < Mangy_Dog> no
2019-09-06T01:34:59 < cracki__> *shrug*
2019-09-06T01:35:05 < Mangy_Dog> i have sloeber for eclipse setup... which i can build for but it cant see the stlink so i have to use arduino to upload with

2019-09-06T01:35:35 < cracki__> I'm gonna keep shrugging
2019-09-06T01:35:45 < Mangy_Dog> then thanks for the help
2019-09-06T01:35:54 < cracki__> you might wanna fix things instead of evading them and using arduino
2019-09-06T01:36:09 < cracki__> ozone was the closest to a standalone debugger I know of
2019-09-06T01:36:14 < cracki__> if it bluescreens, that sucks
2019-09-06T01:36:29 < Mangy_Dog> you might want to actually tell me things or try to help without being a pain in the arse and only hint at ideas rather than actually say something
2019-09-06T01:36:36 < cracki__> but "gnu mcu eclipse" should definitely be able to work somehow
2019-09-06T01:36:47 < cracki__> k then :)

2019-09-06T01:40:10 < salcedo> there's like a world of diff between something like arduino ide and eclipse
2019-09-06T01:40:35 < Mangy_Dog> but thats not the issue
2019-09-06T01:40:41 < Mangy_Dog> i have eclipse working mostly

2019-09-06T01:40:52 < Mangy_Dog> so i cant upload via that

2019-09-06T01:43:19 < Mangy_Dog> fucking rude tbh
2019-09-06T01:43:31 < Mangy_Dog> catphish carbs are easy
2019-09-06T01:43:39 < Mangy_Dog> usually...
2019-09-06T01:43:56 < grummund> is it a discovery board?
2019-09-06T01:44:00 < Mangy_Dog> though tbh... your bike has a carb?
2019-09-06T01:44:04 < Mangy_Dog> grummund no
2019-09-06T01:44:10 < Mangy_Dog> its a custom stm32f103 board
2019-09-06T01:45:13 < grummund> with stlink?
2019-09-06T01:45:27 < catphish> Mangy_Dog: it seemed fairly easy, there are a couple of concerns though, i had to guess the setting for what i think is the "idle mix" screws
2019-09-06T01:45:32 < Mangy_Dog> basically the issue is i think im hitting a memory limit as ive started getting strange values appearing in a variable... but i really shouldnt be hitting the limit yet the program isnt that big. But i am using freertos and an hid library... and i want to see if theyre really taking up that much memory or if its coming from something else
2019-09-06T01:45:54 < catphish> Mangy_Dog: it has 4 carbs!
2019-09-06T01:46:07 < Mangy_Dog> usually if its a common brand bike the air mix or fuel amount screws are easily lookupable

2019-09-06T01:46:27 < Mangy_Dog> "shudder"
2019-09-06T01:48:42 < catphish> Mangy_Dog: i didn't actually think to look it up, instead i just set them by feel the same as they were before i disassembled, hopefully it'll be ok
2019-09-06T01:49:09 < Mangy_Dog> well if you got it wrong youll find out when a fire appears under your seat :p

2019-09-06T01:49:54 < catphish> clearly it's not :)

2019-09-06T01:51:44 < catphish> whether i succeed in fixing it or not, i'm probably going to buy a new one, can't decide between 2009 or 2019 :)
2019-09-06T01:52:08 < catphish> obviously would prefer 2019, 2.5x the price
2019-09-06T01:52:13 < Mangy_Dog> yeah
2019-09-06T01:52:24 < catphish> i love the zx6r though, will def get the same again
2019-09-06T01:52:27 < Mangy_Dog> though wow just checked youre bike si 105bhp the cbr im after is 94 D:
2019-09-06T01:53:45 < catphish> it's absurdly fast
2019-09-06T01:54:04 < Mangy_Dog> tbh i rearly go over 80
2019-09-06T01:54:12 < Mangy_Dog> on a quiet empty motorway
2019-09-06T01:54:22 < Mangy_Dog> im usally a good dog
2019-09-06T01:57:14 < catphish> the reason i rebuilt the carbs is that my bike decided to no longer start hot, most people blamed the float valves
2019-09-06T01:57:36 < catphish> so figured it was worth a try, also got a new battery, new filters, new fuel pump, something ought to work :)
2019-09-06T01:57:41 < catphish> will find out tomorrow
2019-09-06T02:07:35 < kakimir> catphish: how does your bike respond to choke?
2019-09-06T02:08:04 < kakimir> was the bike shit when you bought it or is it recent?
2019-09-06T02:09:44 < catphish> kakimir: recent development, it's been running perfectly for 5 years
2019-09-06T02:09:58 < catphish> then this summer suddenly no hot start
2019-09-06T02:10:12 < kakimir> how do you store it over winter?

2019-09-06T02:11:27 < catphish> (poor thing)
2019-09-06T02:11:32 < catphish> i don't have a garage :(
2019-09-06T02:11:33 < kakimir> gasoline?
2019-09-06T02:11:35 < catphish> yes
2019-09-06T02:11:39 < kakimir> full tank?
2019-09-06T02:11:45 < catphish> yes
2019-09-06T02:11:55 < kakimir> premium or what we call 98octane here?
2019-09-06T02:12:07 < kakimir> E5
2019-09-06T02:12:07 < catphish> i think i usually run it on 95
2019-09-06T02:12:12 < kakimir> E10?
2019-09-06T02:12:21 < catphish> E5 (95)
2019-09-06T02:12:30 < kakimir> oh you have such option :o
2019-09-06T02:13:07 < catphish> sometimes E5 99
2019-09-06T02:13:21 < catphish> but afaik none of my vehicles need > 95
2019-09-06T02:13:55 < Mangy_Dog> i dont look after my bike enough :/
2019-09-06T02:14:05 < Mangy_Dog> i need to strip and sand blast the swing arm
2019-09-06T02:14:06 < catphish> clearly neither do i
2019-09-06T02:14:11 < Mangy_Dog> i had it ourside most of the time
2019-09-06T02:14:15 < Mangy_Dog> not covered
2019-09-06T02:14:22 < Mangy_Dog> even during some of teh winter D:
2019-09-06T02:14:39 < Mangy_Dog> i ride it a lot and its such a pain to lock it up in the store room
2019-09-06T02:14:59 < Mangy_Dog> i do want to setup a little shed for it though
2019-09-06T02:15:05 < Mangy_Dog> but its money i dont have
2019-09-06T02:15:07 < kakimir> my bike is covered in SHIT
2019-09-06T02:15:47 < Mangy_Dog> well im starting to get a decent dusting of rust on teh swing arm :/
2019-09-06T02:16:43 < kakimir> catphish: when will you measure them clearances?
2019-09-06T02:16:52 < Mangy_Dog> well got a new problem managed to intergrate openocd into eclipse but now my prgram wont build inside eclipse :/
2019-09-06T02:16:55 < Mangy_Dog> fails with errors
2019-09-06T02:17:14 < catphish> kakimir: only if my carb rebuild and fuel pump replacement doesn't help
2019-09-06T02:18:03 < Mangy_Dog> but its gone 12 im tired goign to bed
2019-09-06T02:18:11 < Mangy_Dog> will have another go at it tomorrow
2019-09-06T02:18:17 < catphish> good idea :)
2019-09-06T02:19:43 < kakimir> float needle valves may be the issue
2019-09-06T02:19:55 < kakimir> if it's carburetor
2019-09-06T02:20:07 < catphish> kakimir: that's what most poeple suggested on forums
2019-09-06T02:20:16 < catphish> kakimir: i've replaced them ll tonight
2019-09-06T02:20:39 < catphish> will find out tomorrow if it worked, unless i broke the carbs in the process of rebuilding them
2019-09-06T02:21:18 < catphish> but yeah, the main thing i did was replace the float needle valves entirely
2019-09-06T02:21:47 < catphish> alse the idle fuel mix screws, because they were corroded and the maintenance kit i bought came with replacements

2019-09-06T12:33:46 < catphish> PaulFertser: no, it won't start hot under any circumstances
2019-09-06T12:34:52 < catphish> i don't have many ideas left, will replace the fuel pump and filter since they need doing anyway, after that either it's electrical (the wiring or coils) or it's valve related (check the clearance)
2019-09-06T12:38:56 < karlp> specing: what's the phone that's being precious about the usb cables?
2019-09-06T12:39:07 < PaulFertser> catphish: before replacing the pump and filter you can just get a PET bottle and feed the carb(s) directly?
2019-09-06T12:39:39 < PaulFertser> catphish: doesn't your carb have means to attach a transparent tube so that you can look and see where exactly the fuel level is?
2019-09-06T12:40:12 < catphish> PaulFertser: maybe, but i don't have the necessary pipes to hand, and i've for the pump and filter on the way anyway, though i must say, attaching the tank to test every time sucks, wish i did have the pipe / bottl
2019-09-06T12:40:31 < PaulFertser> catphish: do you have a vacuum attachment to the fuel valve on the tank?

2019-09-06T12:41:09 < catphish> yes
2019-09-06T12:41:41 < catphish> err, maybe not
2019-09-06T12:42:04 < catphish> it's very simple, there's a tap, with one outlet, and then a bretaher pipe, nothing else
2019-09-06T12:42:43 < PaulFertser> catphish: a breather pipe on a tap?
2019-09-06T12:42:57 < catphish> sorry, no, just on the tank itself
2019-09-06T12:43:15 < PaulFertser> catphish: anyway, easy to check, open the tap while tank is not connected to the carbs and see if the petrol flows :)
2019-09-06T12:43:41 < catphish> oh, it certainly does, i let some run out just to make sure when i started
2019-09-06T12:43:57 < catphish> also, the bike runs just fine when it's running, and starts fine from cold
2019-09-06T12:44:01 < PaulFertser> catphish: then I'd check if you have proper spark when hot. I understand it should be there if the bike runs when uninterrupted but nevertheless worth checking and seeing. And you'll also see if the spark plug is wet with petrol.
2019-09-06T12:44:08 < catphish> so doesn't really feel like a fuel issue at all
2019-09-06T12:44:30 < catphish> spark when hot seems like the most likely problem (though again, it runs fine hot, just wont start)
2019-09-06T12:44:37 < PaulFertser> catphish: what colour is the spark isolator after it runs for a bit on idle?
2019-09-06T12:45:12 < catphish> that's nontrivial to check, but they seemed pretty clean / golden when i replaced them
2019-09-06T12:46:04 < PaulFertser> Another reason to make a temporary tank out of a bottle
2019-09-06T12:46:56 < PaulFertser> catphish: hm, how about trying a fully charged battery? I know sometimes it's enough to turn the crank but not enough for proper ignition, especially when the mixture is suboptimal.
2019-09-06T12:47:11 < catphish> tried a fully charged battery and a brand new one
2019-09-06T12:47:14 < PaulFertser> And when cold probably your reach mixture is right on spot.
2019-09-06T12:48:11 < PaulFertser> catphish: hm, can it be something odd like a stuck decompressor or some such?
2019-09-06T12:48:41 < catphish> i have no idea what that is
2019-09-06T12:49:07 < PaulFertser> Automatic decompressor keeps the exhaust valves open till certain RPMs are reached.
2019-09-06T12:52:14 < catphish> someone swears the problem on this particular bike that causes it is "valve seat recession"
2019-09-06T12:53:16 < PaulFertser> What's the mechanism?
2019-09-06T12:53:30 < PaulFertser> I mean, how exactly do they explain the problem?
2019-09-06T12:54:22 < catphish> they didn't provide any explanation :)
2019-09-06T12:54:48 < catphish> but there's a lot of talk of this being caused by valve clearances being out
2019-09-06T12:55:36 < PaulFertser> But you can check valves' clearences easily, right?
2019-09-06T12:55:44 < PaulFertser> And you're supposed to do it every now and then anyway.
2019-09-06T12:56:40 < PaulFertser> I've read that with modern engines valve clearance when cold and when fully hot is about the same, and it's only during the warm up phase when it changes.
2019-09-06T12:56:43 < catphish> "easily" is relative, it's a DIY job, but does require a fair amount of extra parts / tools
2019-09-06T12:57:01 < PaulFertser> Feeler gauges and a wrench?
2019-09-06T12:58:30 < catphish> well basically yes, plus the valve spacers
2019-09-06T12:58:36 < PaulFertser> catphish: btw, when hot is the starter rotating the engine "easily" or does it have any visible difficulties? Do you smell petrol from exhaust pipe after trying that? 
2019-09-06T12:58:42 < catphish> plus disaseembling the bike *again* :(
2019-09-06T12:58:54 < PaulFertser> Spacers would be needed when you decide to change the clearance, not for checking ;)
2019-09-06T12:58:56 < catphish> yes, easily, and yes, it seems rich
2019-09-06T12:59:13 -!- Laurenceb_ [~laurence@140.141.208.46.dyn.plus.net] has quit [Ping timeout: 245 seconds]
2019-09-06T12:59:23 < catphish> i'm just reading about people with aftermarket exhausts (like mine) and being too rich
2019-09-06T12:59:49 < catphish> but it seems to come back to valve clearance too
2019-09-06T13:00:43 < PaulFertser> With throttle open carbs' idle system doesn't play much role, the flow should be fully limited by the jets (so the needles shouldn't affect anything as well).
2019-09-06T13:01:06 < PaulFertser> Did you try starting it with throttle fully open and keeping the starter running for like 5 seconds or so?
2019-09-06T13:01:43 < catphish> yes
2019-09-06T13:02:15 < catphish> sometimes opening the throttle does help, other times it doesn't, it always seems to turn over more easily with the throttle open (dunno why that is)
2019-09-06T13:02:53 < PaulFertser> So basically your current theory is that valve seats got worn out somewhat and that the clearance is too low (or not present at all) and so the valves are not opening enough?
2019-09-06T13:03:19 < PaulFertser> With throttle open it's much easier to "suck" mixture :)
2019-09-06T13:03:28 < catphish> i actually don't know how valves clearances affect performance, so my theory is not that well developed
2019-09-06T13:03:50 < catphish> i'm only reading about what others say has resolved identical symptoms
2019-09-06T13:04:10 < catphish> which comes down to a combination of "too rich" or "valve clearances)
2019-09-06T13:05:30 < PaulFertser> You can tell if it's too rich or not by looking at spark plugs after letting it run for a bit. 
2019-09-06T13:05:43 < PaulFertser> catphish: btw, have you sync'd your carbs?
2019-09-06T13:06:35 < catphish> i have not (i don't have a pressure gauge), they almost certainly need doing, but wasn't thinking it was related to this problem
2019-09-06T13:07:06 < Mangy_Dog> ok if im going to start using this cubeide then... and i transfer my code over to its workspace... How do i get it to use the stm32duino core library?
2019-09-06T13:07:36 < PaulFertser> You can DIY a suitable device with a transparent tube filled with a liquid. You do not need to know the pressure, you just need to know if it is not equal.
2019-09-06T13:08:02 < PaulFertser> Mangy_Dog: just add all of its files to the project, that'd probably work.
2019-09-06T13:08:13 < catphish> i could DIY some tubes i guess, yeah
2019-09-06T13:08:13 < PaulFertser> (.c , cpp and .h files)
2019-09-06T13:08:19 < Mangy_Dog> D:
2019-09-06T13:09:23 < Mangy_Dog> that wont work btw as there still needs to be a board/chip select menu 
2019-09-06T13:09:53 < PaulFertser> Mangy_Dog: use appropriate -D preprocessor switches
2019-09-06T13:10:40 < Mangy_Dog> sloeber for the most part sorts that out all you do is give it a list of hardware cores and there file locations and you then can select the stup in your project like in arduino ide...
2019-09-06T13:12:49 < Mangy_Dog> though installing those debugger tools into slober seem to have killed thebuilder... my projects no longer build inside eclipse
2019-09-06T13:12:56 < Mangy_Dog> billions of errors
2019-09-06T13:13:03 < Mangy_Dog> (38)
2019-09-06T13:13:34 < Mangy_Dog> but it still indexes perfectly fine for writing
2019-09-06T13:13:44 < PaulFertser> Probably the errors are easy to fix?
2019-09-06T13:14:33 < Mangy_Dog> not really
2019-09-06T13:15:03 < PaulFertser> catphish: I meant the valves are not closing due to lack of clearance. Because if you had too much clearance you'd hear it when starting cold.
2019-09-06T13:17:54 < Mangy_Dog> if youc an make heads or tails of this be my guest https://pastebin.com/wGH26j0W
2019-09-06T13:18:54 < catphish> PaulFertser: thanks, i'll keep reading about it all :)
2019-09-06T13:19:39 < PaulFertser> catphish: sometimes I'm kinda happy my bike has just one carb and I can easily check the spark plug without disassembling anything at all ;)
2019-09-06T13:19:54 < PaulFertser> (and remove the carb too)

2019-09-06T13:42:31 < PaulFertser> catphish: I assume you trying to start it without choke when hot, right? I wonder if your carbs have additional system to make the mixture richer when "cruising" (I assume that means engine braking), it has its own membrane.
2019-09-06T13:42:38 < catphish> PaulFertser: just tried one more time, disassembled, set the mixture screws to what is generally considered default, started it and it ran great, when it reached 88 degrees idling, it cut out, won't start
2019-09-06T13:43:00 < catphish> i am indeed starting it without choke
2019-09-06T13:43:11 < catphish> i've only usually needed choke in cold weather
2019-09-06T13:43:21 < catphish> though it often helps when cold
2019-09-06T13:43:41 < PaulFertser> With throttle open the mixture screws do not have any say...
2019-09-06T13:43:54 < catphish> that's good to know, that was probably pointless then :)
2019-09-06T13:44:42 < catphish> well i'm basically back to some kind of compression / valve issue then
2019-09-06T13:44:55 < catphish> or possibly an electrical issue (bad coil making bad spark when hot)
2019-09-06T13:45:27 < PaulFertser> But sparks you should be able to check (after dismounting the fuel tank, yes...)
2019-09-06T13:45:44 < PaulFertser> And also the colour says a lot about the mixture.
2019-09-06T13:46:13 < PaulFertser> You can really tell it right away which cylinder gets what quality mixture.
2019-09-06T13:46:29 < PaulFertser> catphish: https://www.tuningmatters.com/wp-content/uploads/2014/07/xspark-plug-lean-rich-optimal-640x360.jpg.pagespeed.ic.9YXGhu6d7U.jpg
2019-09-06T13:47:29 < PaulFertser> (though I guess this pic is mislabled, when fully white it means lean mixture, when brown-ish it's optimal, when black it's rich)
2019-09-06T13:48:08 < PaulFertser> (lean mixture makes everything too hot, so the isolator becomes super-clean)
2019-09-06T13:50:01 < PaulFertser> And of course your spark plugs should be of suitable type for the target engine temperature.
2019-09-06T13:55:18 < PaulFertser> catphish: probably a silly idea but does it start (at all) by pushing on gear, without starter?
2019-09-06T13:56:47 < catphish> PaulFertser: this is a big heavy bike, i'm not inclined to try
2019-09-06T13:58:25 < englishman> saw some dudes on the freeway last night trying to do just that
2019-09-06T13:59:55 < PaulFertser> catphish: you're supposed to ask someone to help you with that. My old 1200cc car was relatively easy to push-start even alone.
2019-09-06T14:00:20 < englishman> why don't you pay a professional a couple hours to mess with it? it could be something easy
2019-09-06T14:00:40 < englishman> and then you won't have to do anything
2019-09-06T14:01:10 < PaulFertser> How to tell a professional from an undereducated fraudster?
2019-09-06T14:01:31 < englishman> clean floors and lots of turnover
2019-09-06T14:03:24 < PaulFertser> When I asked for professional help around here with fixing the spark plug thread I was asked for more money than a whole new cylinder head costs! And it can be swapped even without dismounting the engine from frame!
2019-09-06T14:03:45 < catphish> well, i could pay someone, but at this point it doesn't seem economically viable to do so
2019-09-06T14:04:41 < PaulFertser> I bought a V-coil and did it myself in 30 minutes on a parking lot.
2019-09-06T14:04:47 < englishman> maybe you can give it to laurenceb, he'll be bored soon and will need a project
2019-09-06T14:06:07 < catphish> i'm inclined to give it to whoever wants to collect it :)

2019-09-06T15:08:44 < catphish> PaulFertser: it's not that hard to brake withut ABS, you just let off the brake a touch if you start to skid or stoppie
2019-09-06T15:09:07 < catphish> PaulFertser: yes, it's only happened to me once, but under heavy braking in the dry, yes, the rear wheel will raise
2019-09-06T15:09:16 < catphish> it's both terrifying and awesome (if you live)
2019-09-06T15:09:58 < PaulFertser> catphish: I know the theory :) I'm not sure I'll be able to execute it properly when I face the real need for it though :/
2019-09-06T15:11:02 < catphish> PaulFertser: the only time i did it, i was in 100% autopilot, something pulled in front of me, i paniced, yanked on the brake, started the stoppie, somehow through sheer luck/instinct i managed to control it
2019-09-06T15:11:16 < catphish> i would never wish to repeat it
2019-09-06T15:11:23 < PaulFertser> Some EU research shows about 30% death reduction when comparing same bike models with/without ABS.
2019-09-06T15:12:01 < catphish> the best way to live is to pay more attention in the first place :)
2019-09-06T15:12:08 < catphish> but yeah, i will be looking to get ABS next time
2019-09-06T15:13:23 < PaulFertser> catphish: I would guess you'd be going to practice hard braking in different conditions (wet/dry) in a safe spot (probably big empty shopping centre parking lot) every once in a while.
2019-09-06T15:14:14 < catphish> i often practice approaching lights when there's nobody behind me
2019-09-06T15:15:17 < PaulFertser> On my shitty bike in dry conditions I can neither skid nor lift the rear :/ I have a feeling it's just a weak braking system combined with reasonably decent tyre rather than some malfunction.
2019-09-06T15:24:11 < ThatDamnRanga> Whelp. I solved the problem in my sleep last night
2019-09-06T15:24:17 < ThatDamnRanga> but I can't remember the solution
2019-09-06T15:24:42 < ThatDamnRanga> ... It's at this point I've decided to take a couple days off, insomnia combined with dreaming about it... not good xD
2019-09-06T15:25:38 < ThatDamnRanga> also catphish, not familiar with the problem, but correctly tuned bike carbs will need the choke to start and for the 30 seconds following, at 25c.
2019-09-06T15:26:19 < ThatDamnRanga> also, there are EFI conversions available for the ZX6 engine, it may be worth your time

2019-09-06T16:51:39 < karlp> just kicad export of the pcb.
2019-09-06T16:51:52 < dongs> ah.. altipro has that collision stuff built in
2019-09-06T16:52:02 < dongs> you can import steps into existing pcb :p
2019-09-06T16:52:41 < karlp> yeah, that's what I've done

2019-09-06T16:55:25 < PaulFertser> The got to be some gotcha, no way soldering pro can't do this board without mistakes in 60 minutes time.
2019-09-06T16:55:33 < dongs> right??

2019-09-06T16:56:15 < dongs> it was open to the public
2019-09-06T16:56:27 < dongs> PaulFertser: cuz they're reveresd on pcb
2019-09-06T16:56:32 < dongs> one is up one is down
2019-09-06T16:56:34 < dongs> prolly for torlling
2019-09-06T16:56:36 < dongs> trolling
2019-09-06T16:56:38 < dongs> but yeah even then
2019-09-06T16:56:49 < PaulFertser> + mark on silk is pretty obvious though
2019-09-06T16:57:40 < PaulFertser> What's the smallest component? Is that R6 like 0402?
2019-09-06T16:58:02 < dongs> that looks like 0402 yea
2019-09-06T16:58:07 < dongs> and 0603 led next to it

2019-09-06T17:07:23 < PaulFertser> Are they probably given a board full of mistakes and the task is to rework it? Rotate the QFP part etc.
2019-09-06T17:07:53 < PaulFertser> Doesn't look like that from the video
2019-09-06T17:08:31 < dongs> the world REWORK championship is, yes
2019-09-06T17:08:40 < dongs> the hand-soldering one i linked the pdfs from is just assemble
2019-09-06T17:08:48 < dongs> the video, 1st guy starts with a blank board and those parts on tape

2019-09-06T17:10:53 < PaulFertser> Probably those are just random trade show participants?
2019-09-06T17:11:03 < dongs> no, there was preregistration.
2019-09-06T17:11:09 < dongs> you register, they send you a blank oard + parts
2019-09-06T17:11:14 < dongs> you assemble + time and send back
2019-09-06T17:11:21 < veverak> hmm
2019-09-06T17:11:21 < dongs> then they choose to take you in or not
2019-09-06T17:11:32 < veverak> do you put checksum at the end of uart messages?
2019-09-06T17:11:32 < dongs> the deadline for that was in july, so i missed that.
2019-09-06T17:11:39 < veverak> or, what is cool to use these days?
2019-09-06T17:11:49 < dongs> veverak: NMEA has checksums after *

2019-09-06T17:13:32 < veverak> xor of bytes it is
2019-09-06T17:26:30 < dongs> man i wanted to open a cube project
2019-09-06T17:26:34 < dongs> and it wanted to update
2019-09-06T17:26:38 < dongs> and today STs site is slow as crap
2019-09-06T17:26:43 < dongs> now its leeching 300megs of shit at like 250k/sec
2019-09-06T17:29:37 < PaulFertser> veverak: why would one do xor of bytes, why?..
2019-09-06T17:30:41 < veverak> why not?
2019-09-06T17:30:58 < veverak> I mean, it should be enough (as low enough chance of collision) and is fast to compute
2019-09-06T17:31:37 < PaulFertser> Are you on a super-constrained target or what?

2019-09-06T17:36:19 < Mangy_Dog> Is there something else I need to do inside freertos for it to allow the analyzer to read data?
2019-09-06T17:55:51 < catphish> Mangy_Dog PaulFertser sold it :)
2019-09-06T17:56:52 < PaulFertser> catphish: wow! Congrats!
2019-09-06T17:57:18 < catphish> well, not a great win, but at least i can stop worrying about it, and start looking at new ones
2019-09-06T17:58:42 < Mangy_Dog> :o
2019-09-06T17:58:44 < Mangy_Dog> cool
2019-09-06T17:58:48 < Mangy_Dog> i assume you mean solved it :p
2019-09-06T17:59:15 < PaulFertser> catphish: so what was it?
2019-09-06T17:59:27 < catphish> no
2019-09-06T17:59:30 < catphish> i mean sold it.

2019-09-06T17:59:38 < catphish> lol

2019-09-06T17:59:51 < catphish> sadly not a typo :)
2019-09-06T18:03:18 < PaulFertser> How long were you struggling with it?
2019-09-06T18:04:27 < Mangy_Dog> you sold the carb?
2019-09-06T18:04:36 < Mangy_Dog> the one you were trying to fix?
2019-09-06T18:05:37 < PaulFertser> The bike
2019-09-06T18:06:04 < Mangy_Dog> ooohhhhhhh
2019-09-06T18:06:11 < PaulFertser> Probably got convinced he needs ABS ;)
2019-09-06T18:11:15 < BrainDamage> I'd love to have an optional abs on my mountain bike
2019-09-06T18:12:11 < BrainDamage> treshold braking is rather tiring when the road conditions continously change, your posture also changes the load on the brakes so you have to consider that too
2019-09-06T18:17:35 < karlp> fucking net ties, how do they work.
2019-09-06T18:17:35 < PaulFertser> On dirt/gravel abs might do more harm than good.
2019-09-06T18:18:01 < karlp> I thought this would give me named nets so I could lay them out, but still just drop a big "gnd" pour and have the nettie sort out that thy all go togther.
2019-09-06T18:18:15 < karlp> but no, no I've got a little pad footprint for the nettie.
2019-09-06T18:18:38 < BrainDamage> PaulFertser: that's why I said optional
2019-09-06T18:18:40 < karlp> am I meant to route say, gndd manually, and just tie it at one point to the big gnda pour?

2019-09-06T19:44:56 < Cracki> lots of actors in their 50s somehow still look good
2019-09-06T19:45:07 < Cracki> must be all the baby blood
2019-09-06T19:45:32 < specing> A lot of make-up combined with photoshop?
2019-09-06T19:46:17 < Cracki> video editing isn't that good yet
2019-09-06T19:46:58 < roomba> yea it's just good lighting and make-up and stuff
2019-09-06T19:47:10 < Cracki> they do a lot by just keeping their skin tight
2019-09-06T19:48:53 < jadew> there must be some makeup in there too
2019-09-06T19:49:06 < jadew> she looks way too young to be 50
2019-09-06T19:52:36 < Cracki> did ya watch house ms? lisa cuddy's actor was around 50 when she did the cheerleader striptease
2019-09-06T19:52:57 < Cracki> there is medical magic to firm up bodies
2019-09-06T19:53:05 < jadew> looking it up as we speak
2019-09-06T19:53:23 < Cracki> infant blood, as I said
2019-09-06T19:54:03 < BrainDamage> there's also selection bias, if she didn't look young, she wouldn't have got the role
2019-09-06T19:54:57 < jadew> Cracki, can't find it
2019-09-06T19:55:13 < jadew> BrainDamage, yeah
2019-09-06T19:55:48 < BrainDamage> many actors retire early as they start to age

2019-09-06T19:56:26 < jadew> really? leave while you're ahead kind of thing?
2019-09-06T19:57:35 < jadew> Anyone who looks like that and says she hasn’t done any kind of enhancement isn’t telling the truth.
2019-09-06T19:57:50 < jadew> ok, I'll believe that
2019-09-06T19:57:53 < Cracki> "no surgery" means no knife
2019-09-06T19:58:09 < jadew> ah, I see
2019-09-06T19:58:13 < Cracki> doesn't mean it's not a replicant
2019-09-06T19:58:44 < Cracki> grey's anatomy, most of them are in their late 40s to early 50s
2019-09-06T19:58:57 < Cracki> and they are still passed of as 30s
2019-09-06T19:59:15 < jadew> jezz...
2019-09-06T19:59:38 < jadew> as a guy, you get a lot more attention as you get older
2019-09-06T19:59:49 < Cracki> guys age gracefully
2019-09-06T19:59:57 < Cracki> if they don't let themselves go
2019-09-06T20:03:38 < jadew> I've noticed that a lot lately, but sadly I started losing hair
2019-09-06T20:03:59 < Cracki> look up elon musk now vs in his paypal days
2019-09-06T20:04:13 < Cracki> somehow he either gained back hair or had a forehead-plasty or something
2019-09-06T20:04:33 < jadew> heh
2019-09-06T20:05:03 < jadew> I have a friend who has been bald since he was in his early 20s and managed to grow it back with some treatment
2019-09-06T20:05:11 < Cracki> if all else fails, do what the book store owner does: https://steemitimages.com/640x0/https://pbs.twimg.com/media/DEzQy2nXgAA1boJ.jpg
2019-09-06T20:05:23 < jadew> I could ask him for what he did, but I'm not sure I want to trouble myself with that
2019-09-06T20:05:36 < jadew> I can just shave it every 4 weeks or so
2019-09-06T20:05:37 < Cracki> ah, it's just a proper hair cut that doesn't flare out the sides: http://staticimg.albanydailynews.com/wp-content/uploads/Elon-Musk.jpg
2019-09-06T20:06:13 < jadew> ok, he was bald
2019-09-06T20:06:39 < Cracki> they say it's a transplant https://www.hairguard.com/elon-musk-hair/
2019-09-06T20:06:49 < jadew> lol
2019-09-06T20:08:17 < Cracki> hah they took hair from a stripe around the back of his head, like a band between the ears

2019-09-06T20:09:15 < jadew> how old was he?
2019-09-06T20:10:00 < Cracki> he's 48 now, paypal was 1999-2000
2019-09-06T20:10:05 < Cracki> so... around 30
2019-09-06T20:10:29 < jadew> so there's hope for me too
2019-09-06T20:10:38 < Cracki> the video where the strip is visible looks recentish because it's about the boring company
2019-09-06T20:10:50 < jadew> I can take some of the hair that recently started growing on my belly
2019-09-06T20:10:53 < Cracki> hope meaning you pay someone to rearrange your hair
2019-09-06T20:10:57 < Cracki> hahaha
2019-09-06T20:11:24 < Cracki> that might look more like pubic hair than anything else
2019-09-06T20:11:45 < jadew> haha, that would look awkward, yeah
2019-09-06T20:11:54 < Cracki> besides, imagine the impression you make when you're bald but otherwise hairy as fuck
2019-09-06T20:12:48 < BrainDamage> that's actually somewhat common
2019-09-06T20:12:50 < Cracki> keeping it short like an english lawn says "I'm civilized but a brute at heart"
2019-09-06T20:12:56 < Cracki> the body hair, that is
2019-09-06T20:13:04 < BrainDamage> the same hormones that cause hair loss cause body hair growth
2019-09-06T20:13:40 < jadew> BrainDamage, no way! I wanted to say that I observed that the hair loss started about the same time when hair started to grow on other parts of my body
2019-09-06T20:13:46 < jadew> that's such a bad deal...
2019-09-06T20:13:50 < Cracki> typical male pattern baldness. hits transsexuals too, when they still hope to grow long feminine hair... and get a huge forehead instead.
2019-09-06T20:14:07 < jadew> lol
2019-09-06T20:14:19 < jadew> that must suck so bad
2019-09-06T20:14:27 < Cracki> monk heads in skirts, it's hilarious
2019-09-06T20:15:28 < Cracki> oh, elon owns x.com again, bought it from paypal for "sentimental" value
2019-09-06T20:15:52 < Cracki> I'm sure spaceX is just the first part of a huge X-themed conglomerate of futuristic things
2019-09-06T20:16:35 < Mangy_Dog> what have i got wrong on here? the return val; is throwing an error
2019-09-06T20:16:40 < Mangy_Dog> https://pastebin.com/PBDn2LQ4
2019-09-06T20:17:01 < BrainDamage> the function expects a void return
2019-09-06T20:17:13 < Mangy_Dog> i need to set function to a datatype
2019-09-06T20:17:32 < jadew> you quit half way through the tutorial?
2019-09-06T20:17:42 < Cracki> I'll hold my tongue
2019-09-06T20:17:46 < Mangy_Dog> i forgot
2019-09-06T20:18:34 < Cracki> ok I'll not; that's not "throwing" an error, the compiler already refuses to compile this, with a very precise message saying that you try to return a value from a void function
2019-09-06T20:18:58 < Mangy_Dog> actually the error said returned null
2019-09-06T20:19:04 < Cracki> also the math will fuck up
2019-09-06T20:19:05 < Mangy_Dog> anyway fixed now
2019-09-06T20:19:13 < Mangy_Dog> why?
2019-09-06T20:19:22 < Cracki> either use some parens or another /100
2019-09-06T20:19:42 < BrainDamage> because only the second operand gets the /100
2019-09-06T20:19:52 < Cracki> sure why not
2019-09-06T20:20:07 < BrainDamage> Mangy_Dog: learn operator precedence
2019-09-06T20:20:25 < Cracki> knowing is not the issue, he assumes precedence when doing * and +
2019-09-06T20:20:28 < BrainDamage> or just pretend your code is (((lisp)))
2019-09-06T20:20:55 < Cracki> if you want (((lisp))) use clisp
2019-09-06T20:21:10 < Mangy_Dog> its amazing, with some tact you could say all that without coming across as insulting
2019-09-06T20:21:11 < Cracki> it has one of those seven pronged candle thingies
2019-09-06T20:21:11 < jadew> I never used lisp, is it good for anything?
2019-09-06T20:21:41 < Mangy_Dog> and yes made a little mistake... sorry. I havnt done any programming for a good few months before getting back into this project. and i forgot.
2019-09-06T20:21:48 < Cracki> lisp is different. the value is probably in the libraries and the community.
2019-09-06T20:22:20 < Cracki> the language itself isn't for convenient scripting, so doesn't have any syntax like python does, but it does have ways to extend syntax
2019-09-06T20:23:22 < Cracki> in a venn diagram with other languages, it's definitely not a subset or superset
2019-09-06T20:23:54 < Cracki> lisp got hyped in the 80s when artificial intelligence raced down the logic and symbolic manipulation deadend
2019-09-06T20:24:23 < BrainDamage> lisp is useful to read SICP
2019-09-06T20:24:47 < Cracki> it kept its popularity because it gave people dynamic typing when there were no feasible languages with that feature
2019-09-06T20:25:20 < BrainDamage> also, with / being lower priority of + and *, that code would not have problems without parenthesis, ofc it makes little sense to have * and / having different priorities, but it's not automatic
2019-09-06T20:25:20 < Cracki> if you wanted a read-eval-print-loop, you used lisp

2019-09-06T21:42:34 < catphish> PaulFertser: i was struggling with it for about 2 weeks, did a lot of work this last week, but ultimately got fed up of guessing and spending money on non-fixes
2019-09-06T21:42:56 < catphish> i'm not a mechanic, and the bike isn't worth enough to pay one
2019-09-06T21:43:13 < catphish> ultimately i just want one that works :)
2019-09-06T21:45:17 < PaulFertser> catphish: what are your usecases btw, and how many kms per year do you ride?
2019-09-06T21:58:17 < catphish> PaulFertser: fun fast commuting / travelling to sports events when the weather is good, about 2,000 km/year
2019-09-06T21:58:35 < catphish> any generally getting places fast when i don't feel like sitting in traffic
2019-09-06T21:59:47 < PaulFertser> catphish: wow, even I do 5-6 kkm per year, and that means riding just about 6 months of it :)
2019-09-06T22:00:06 < catphish> i ride only have the year, and only half the days of the week
2019-09-06T22:00:09 < catphish> *half
2019-09-06T22:01:05 < catphish> less the times when i can't ride it because i'm an idiot and forgot to get its annual inspection
2019-09-06T22:01:13 < PaulFertser> catphish: why only half the year, are you in canada or something? :)
2019-09-06T22:01:25 < catphish> i live in the UK and don't like riding in the rain
2019-09-06T22:01:36 < catphish> nb. it's always raining here
2019-09-06T22:02:13 < PaulFertser> Oh heh, makes sense then. I usually ride from the time I'm kinda sure there's no ice on the road till I'm sure there might be some in the morning.
2019-09-06T22:03:37 < catphish> the way i ride in comparison to my skill level doesn't suit wet roads
2019-09-06T22:03:46 < PaulFertser> Aren't your cops strict enough for any fun fast commuting to be effectively impossible?
2019-09-06T22:03:52 < catphish> a new bike with ABS may improve that ratio
2019-09-06T22:04:04 < catphish> lol no
2019-09-06T22:04:39 < PaulFertser> So what do you plan for the next bike? MT09?
2019-09-06T22:04:54 < PaulFertser> I've heard it's fast and really fun.
2019-09-06T22:05:03 < catphish> this is a shortlist of ideas right now: https://paste.ubuntu.com/p/ZTBqt4xxxy/
2019-09-06T22:05:43 < PaulFertser> Triumph Speed Triple
2019-09-06T22:06:14 < PaulFertser> j/k, I understand you're on budget.
2019-09-06T22:08:53 < PaulFertser> catphish: are you happy having all the plastic? I thought it's too easy to damage, and what's real advantage for relatively short commutes anyway, why are you not looking at naked streetfighters?

2019-09-06T22:13:22 < catphish> PaulFertser: i like the coloutful plastic, i can't explain it, i just like it
2019-09-06T22:13:28 < PaulFertser> And I've also read people prefer V/L-twins for fun, thanks to torque at lower RPMs.
2019-09-06T22:13:46 < catphish> also, most of the fastest bikes have the plastic
2019-09-06T22:13:54 < catphish> also, i prefer very high RPMs
2019-09-06T22:13:56 < PaulFertser> You already had 4-cylinder inline enginer, probably it's about time to try something else?
2019-09-06T22:14:29 < catphish> my interest can largely be expressed as a value of acceleration :)
2019-09-06T22:15:36 < PaulFertser> Those bikes are good for track racing indeed, but for street hooligans probably not so efficient.

2019-09-06T22:30:49 < PaulFertser> I'm not suggesting you try V-max even though it's the most acceleration you can get for the price ;) But while you're at the crossroads I guess it'd make sense to try looking past your beloved 600cc sportbikes :)

2019-09-06T22:34:46 < catphish> the VMAX is on there, 3.3s :)
2019-09-06T22:35:06 < catphish> it's ugly as all hell though by my 90s standards
2019-09-06T22:35:25 < catphish> i likes my plastic
2019-09-06T22:36:15 < PaulFertser> Probably you'll like track training too? Much safer than riding on streets, and probably even more fun.
2019-09-06T22:41:40 < catphish> almost certainly, not easy to find the track / time though
2019-09-06T22:43:51 < PaulFertser> Boost your skills to avoid something like http://www.youtube.com/watch?v=m0rQ8s1lKxQ&t=382
2019-09-06T22:49:50 < catphish> oops
2019-09-06T22:51:42 < catphish> they literally just drove off the road
2019-09-06T22:52:11 < catphish> looks dumb but insanely easy to do if you don't train yourself to look round bends properly
2019-09-06T22:52:55 < PaulFertser> Apparently she could ride relatively fast directly following what a person ahead was doing. But when she needed to turn on her own, too bad, lack of cornering training.
2019-09-06T22:53:43 < catphish> i read that most people's accidents happen because they panic and won't turn enough because they don't trust the bike
2019-09-06T22:54:29 < catphish> annoyingly the only (very minor) accident i've had was a result of the opposive, i pushed too hard round a bend, must have been something on the road, and the bike just slid out from under me
2019-09-06T22:54:58 < catphish> annoyingly since then i have less trust in the bike, and have almost understeered (per that video) a couple of times
2019-09-06T22:55:33 < catphish> riding a fast bike is certainly not easy, but for the most part, as long as you plan properly, it's great
2019-09-06T22:55:59 < catphish> poor planning or not paying attention = likely death :)
2019-09-06T22:56:00 < PaulFertser> A low side is usually much safer than any kind of high side.
2019-09-06T22:56:55 < catphish> yeah that's what happened to me, suddenly the bike just wasn't under me any more, i jumped off it and it slid away from me
2019-09-06T22:57:27 < PaulFertser> And on the track you have safety zones where you can skid on your racing gear without damages. Public roads are just not suitable for the kind of riding sportbikers like.
2019-09-06T22:57:38 < catphish> i had nothing more than grazed knees and bruised palms
2019-09-06T22:57:53 < PaulFertser> Loose knee guard?
2019-09-06T22:58:00 < catphish> jeans
2019-09-06T22:58:42 < catphish> not the best protection it turns out
2019-09-06T22:59:07 < catphish> i usually ride in jeans / bike jacket / bike gloves
2019-09-06T22:59:25 < catphish> but will wear full bike suit if i'm planning to ride fast
2019-09-06T22:59:50 < catphish> (oh and always bike boots)
2019-09-06T23:00:14 < catphish> jeans always just seem more practical for commuting
2019-09-06T23:00:32 < catphish> i see kids on bikes with t-shirts on, i have no idea what's wrong with them
2019-09-06T23:01:02 < PaulFertser> Just no fear.
2019-09-06T23:04:04 < PaulFertser> catphish: do you have any moto gymkhana enthusiasts nearby? That might help regain the trust in bikes' abilities to lean.
2019-09-06T23:04:32 < catphish> not that i'm aware of
2019-09-06T23:04:37 < PaulFertser> (with appropriate sliders installed to save the plastic)
2019-09-06T23:04:38 < catphish> i might head to a track some time
2019-09-06T23:04:52 < catphish> or do some offroad biking or similar
2019-09-06T23:05:00 < catphish> get a feel for sliding around on small bikes
2019-09-06T23:05:07 < PaulFertser> gymkhana is what you can do once or twice a week for free, just fun spending time with other bikers on a parking lot.

2019-09-07T00:13:35 < PaulFertser> It's not like it needs to get any data from Earth to complete the landing so if just the telemetry was lost it didn't mean it's not doing the right thing.
2019-09-07T00:13:40 < Ultrasauce> well, its pretty nontrivial to distinguish loss of telemetry due to exploding from loss of telemetry due to one of a thousand other non-explodey things
2019-09-07T00:14:10 < jadew> Ultrasauce, it went off-course tho
2019-09-07T00:14:39 < jadew> I'm sure everyone was hoping that it went off course and didn't plummet into the moon in the next 5 seconds

2019-09-07T01:29:21 < karlp> so I'm ok with aisler.  it'll even be rohs and shit.
2019-09-07T01:30:13 < karlp> the aisler ones will even be enig

2019-09-07T01:48:44 < Mangy_Dog> think im going to remove freertos from my project
2019-09-07T01:48:54 < Mangy_Dog> i can do most of what i need to do with a simple scheduler
2019-09-07T01:49:04 < mawk> ?
2019-09-07T01:49:08 < Mangy_Dog> and it takes next to no memory
2019-09-07T01:49:27 < mawk> just configure freertos to only have the components you need
2019-09-07T01:49:30 < Mangy_Dog> im just having sooooo many issues with freertos right now and i think memory is corrupting somewhere and causing errored values
2019-09-07T01:49:39 < mawk> you're using libc ?
2019-09-07T01:49:43 < mawk> printf, things like that
2019-09-07T01:49:53 < mawk> anything from regular C, that is
2019-09-07T01:50:02 < Mangy_Dog> dont think so
2019-09-07T01:50:12 < mawk> no strlen, no printf, no nothing
2019-09-07T01:50:17 < Mangy_Dog> noe
2019-09-07T01:50:19 < Mangy_Dog> nope
2019-09-07T01:50:20 < mawk> ok good
2019-09-07T01:50:32 < mawk> I don't know if it's possible to run valgrind on stm32
2019-09-07T01:50:39 < mawk> but that's the gold standard of finding memory corruption
2019-09-07T01:50:49 < Mangy_Dog> no idea
2019-09-07T01:51:11 < Mangy_Dog> thats the other thing ive not been able to get any debugging tool to talk to the rtos
2019-09-07T01:51:20 < Mangy_Dog> and i was only using it for the scheduler anyway
2019-09-07T01:51:47 < Mangy_Dog> i can use the simple arduino task schedular to do what i want set my intervals.... sure its not true realtime task shearing
2019-09-07T01:51:54 < Mangy_Dog> sharing
2019-09-07T01:52:06 < Mangy_Dog> but at it will do
2019-09-07T01:52:33 < Mangy_Dog> and i wont have these memory problems :/
2019-09-07T01:52:45 < Mangy_Dog> as theres NO way what ive written has filled up the ram of ny mcu
2019-09-07T01:53:18 < BrainDamage> you're using dynamic allocation?

2019-09-07T09:38:28 < PaulFertser> ThatDamnRanga: while at it, you can order a salea clone to have an 8-channel LA added to your toolbox.
2019-09-07T09:39:45 < PaulFertser> ThatDamnRanga: and btw, regardless of the library you use it often makes sense to read its sources while cross-referencing with the chip family reference manual, and checking peripheral registers directly from a debugger.
2019-09-07T09:40:12 < PaulFertser> And ST can't be trusted with their libraries.
2019-09-07T09:40:27 < ThatDamnRanga> PaulFertser, this was worse... two layers deep into mbed lol
2019-09-07T09:40:40 < PaulFertser> Oh my, congrats for solving it.
2019-09-07T09:40:47 < PaulFertser> Did you send a patch to mbed? ;)
2019-09-07T09:41:02 < ThatDamnRanga> I may do that
2019-09-07T09:41:14 < PaulFertser> LAs based on fx2lp are dirt cheap
2019-09-07T09:41:40 < ThatDamnRanga> thats what this hantek scope is based ion
2019-09-07T09:42:00 < PaulFertser> So it has plenty of logic channels, not two analog?
2019-09-07T09:42:30 < ThatDamnRanga> hmm, I might be getting my wires crossed
2019-09-07T09:42:41 < ThatDamnRanga> it has an unpopulated header for a 16ch LA
2019-09-07T09:42:49 < ThatDamnRanga> but only the two analogue channels are broken out
2019-09-07T09:46:18 < PaulFertser> Devices I'm talking about are basically fx2 breakout boards with suitable probes.
2019-09-07T09:48:21 < ThatDamnRanga> Appears I'm mistaken. https://www.eevblog.com/forum/testgear/hantek-6022be-20mhz-usb-dso/
2019-09-07T09:48:26 < ThatDamnRanga> runs the fx2lafw though

2019-09-07T10:13:42 < ThatDamnRanga> PaulFertser, indeed, when I need oscilloscope mode. Using sigrok when I need LA
2019-09-07T10:13:52 < ThatDamnRanga> (Pulseview is something else)
2019-09-07T10:15:06 < PaulFertser> ThatDamnRanga: Pulseview is sigrok GUI interface, I know :)
2019-09-07T10:16:30 < ThatDamnRanga> nono... "Something else" as in the colloquial form, not the literal form
2019-09-07T10:20:00 < PaulFertser> Ah :)
2019-09-07T10:20:36 < PaulFertser> ThatDamnRanga: how do you like mbed so far (if not for the gotcha you faced)?

2019-09-07T12:04:35 < srk> risc-v fan? :)
2019-09-07T12:05:44 < dongs> i like thier stdperiph
2019-09-07T12:05:49 < dongs> more than ST's
2019-09-07T12:06:09 < srk> stdperiph? what's that?
2019-09-07T12:06:19 < srk> is it possible to buy it somewhere already?
2019-09-07T12:06:20 < dongs> ? are you trolling
2019-09-07T12:06:25 < dongs> GD32V? yeah
2019-09-07T12:06:35 < dongs> seeedstudio ro wahtever has a redpill-like evalboard
2019-09-07T12:06:38 < dongs> with GD32V and LCD on it
2019-09-07T12:06:44 < srk> no, standard periherals? thought they are compatible with STs

2019-09-07T12:06:55 < srk> but looks cool
2019-09-07T12:06:58 < dongs> yes, but ST forced them to rename their stuff
2019-09-07T12:07:06 < dongs> yea that one. it ships sept12 or so
2019-09-07T12:07:11 < dongs> orders from inside china already shipoped
2019-09-07T12:07:12 < srk> nice
2019-09-07T12:07:35 < dongs> > thought they are compatible with STs
2019-09-07T12:07:44 < dongs> yes but ST forced (?) them to rename the APIs and registers
2019-09-07T12:07:48 < dongs> so it didnt look like 100% copy
2019-09-07T12:07:55 < dongs> and as a result they actually improved readability of the api
2019-09-07T12:07:56 < srk> are there any docs?
2019-09-07T12:08:08 < dongs> yes, theres docs/refman/stdperiph/examples/etc.

2019-09-07T12:10:50 < dongs> haha
2019-09-07T12:10:52 < dongs> i wonder if thats eclipse
2019-09-07T12:11:34 < srk> uu, even svd file
2019-09-07T12:11:39 < dongs> yes
2019-09-07T12:13:33 < srk> lol, certainly renamed, are they bit-wise compatible at least so we can rename back? :)
2019-09-07T12:14:10 < dongs> i think so, they were supposed to be binary-ish compatble
2019-09-07T12:14:14 < dongs> xcept i2c peripheral which got fixed up
2019-09-07T12:14:49 < srk> good!
2019-09-07T12:15:24 < srk> old i2c looked terrible anyway, the new one is much easier to implement
2019-09-07T12:20:23 < ThatDamnRanga> Maybe that's what prompted ST to change up their i2c periph
2019-09-07T12:20:30 < dongs> pls no
2019-09-07T12:20:35 < dongs> they had the v2 i2c in F3s or whatever
2019-09-07T12:20:39 < dongs> way before the clones
2019-09-07T12:20:40 < ThatDamnRanga> Ah okay
2019-09-07T12:20:49 < ThatDamnRanga> idk. I didn't know there were clones til now

2019-09-07T14:10:03 < kakimir> I just realized that if I "dd" a full system from hdd to ssd that ssd doesn't know what parts are to be trimmed
2019-09-07T14:10:30 < kakimir> let's say it's a linux system
2019-09-07T14:10:34 < kakimir> what do I do?
2019-09-07T14:13:56 < kakimir> oh wow
2019-09-07T14:14:08 < kakimir> ddrescue had parameter --retrim
2019-09-07T14:15:00 < kakimir> but it's not the trim I'm looking for :o
2019-09-07T14:19:22 < kakimir> how bad it is to erase ssd just by writing zeros?
2019-09-07T14:23:32 < Steffanx> Its useless
2019-09-07T14:23:43 < kakimir> does it nuke the data+
2019-09-07T14:23:47 < kakimir> ?
2019-09-07T14:23:55 < Steffanx> Not entirely.
2019-09-07T14:24:20 < kakimir> hey wow
2019-09-07T14:24:28 < kakimir> imma stupid
2019-09-07T14:24:55 < kakimir> if I dd my hdd there it overwrites shit
2019-09-07T14:25:16 < kakimir> as it's the exact same size
2019-09-07T14:25:24 < srk> Steffanx: why not? you could recover data from hdds if you overwrote them with zeroes, does it hold for ssds as well?
2019-09-07T14:26:48 < kakimir> controller might just store information of zero block size or so
2019-09-07T14:27:08 < srk> true
2019-09-07T14:27:28 < dongs> hmm
2019-09-07T14:27:33 < dongs> huawei iot studio is only 150megs
2019-09-07T14:27:36 < dongs> that cant be eclipse
2019-09-07T14:29:26 < kakimir> it's arduino studio?
2019-09-07T14:29:42 < dongs> heh no it just cli versions of gcc and openocd
2019-09-07T14:30:01 < kakimir> that's it?
2019-09-07T14:32:07 < kakimir> barelly anything to call it a studio?

2019-09-07T15:30:31 < Mangy_Dog> silly question im kinda assuming the awnser is yes but want to be sure... I know arduino atmegas can do it. But i have a feeling i read stm32s cant.... Anyway Is is possible to store configuration (or any data for that matter) into the built in flash at run time? So say i do a calibration of some sensors. And I want to set those values in a space bit of flash... is that possible?
2019-09-07T15:30:44 < Steffanx> such monetized westener, tcth
2019-09-07T15:30:54 < Steffanx> is what mr Thorn would say.
2019-09-07T15:31:18 < Steffanx> isnt that what i kinda said srk? > it's useless.
2019-09-07T15:31:47 < Steffanx> and doesnt a SSD move blocks around? Logical > physical block mapping et all.
2019-09-07T15:33:22 < invzim> Mangy_Dog: yes it's possible
2019-09-07T15:33:27 < tcth> Mangy_Dog, totally possible
2019-09-07T15:33:34 < tcth> Mangy_Dog, google ´´stm32 write to flash´´
2019-09-07T15:33:47 < tcth> Mangy_Dog, if you are using the official CubeHAL stuff: They should have drivers for that
2019-09-07T15:33:55 < Thorn> not "monetized". moneyed
2019-09-07T15:34:01 < Mangy_Dog> not using hal but will see if anyones mae something for stm32duino
2019-09-07T15:34:02 < invzim> Mangy_Dog: get https://leanpub.com/mastering-stm32
2019-09-07T15:34:03 < Mangy_Dog> thanks
2019-09-07T15:34:09 < Steffanx> want me to look into the logs Thorn?
2019-09-07T15:34:21 < Steffanx> there is eeprom emulation libs too, if you want something more fancy
2019-09-07T15:34:23 < Steffanx> are*
2019-09-07T15:34:41 < Mangy_Dog> shouldnt need anything too fancy maybe only need to store 4 or 6 values
2019-09-07T15:34:57 < Mangy_Dog> 16bit values mind
2019-09-07T15:35:04 < Steffanx> no need for wear leveling?
2019-09-07T15:35:04 < Mangy_Dog> so 12 clusters i guess
2019-09-07T15:35:10 < Steffanx> how often do you want to write those values
2019-09-07T15:35:23 < Mangy_Dog> a handful of times in the products life
2019-09-07T15:35:27 < Mangy_Dog> maybe 10 at the most
2019-09-07T15:35:29 < Steffanx> oh ok
2019-09-07T15:35:51 < invzim> some(all?) also have a one-time-programmable section that can be most useful
2019-09-07T15:35:56 < Mangy_Dog> its just joycon calibration data
2019-09-07T15:36:08 < Steffanx> if i only knew what joycon is
2019-09-07T15:36:21 < Thorn> Steffanx: be my guest sir
2019-09-07T15:36:28 < Mangy_Dog> min and max values and maybe a middle value as it seems these sticks arent quite linear in there resistance values
2019-09-07T15:36:38 < Mangy_Dog> steff the analog sticks on game pads
2019-09-07T15:37:58 < Steffanx> Sorry Thorn

2019-09-07T17:54:57 < Mangy_Dog> though he would get super special treatment
2019-09-07T17:55:04 < Mangy_Dog> straight to catd 
2019-09-07T17:55:16 < roomba> Boris Inside(tm) *jingle*
2019-09-07T17:55:24 < Mangy_Dog> bypassing all the usual parole hearings to get to catdpeople normally have to go through
2019-09-07T17:55:41 < Mangy_Dog> so he wont actually whitness how fucking horrific britis jails really are
2019-09-07T17:56:11 < Mangy_Dog> it amazes me how quick MPs who go inside get put to catD
2019-09-07T17:56:11 < roomba> are they horrific tho?
2019-09-07T17:56:15 < Mangy_Dog> yes they are
2019-09-07T17:56:28 < Mangy_Dog> some worse than others some better
2019-09-07T17:56:38 < Mangy_Dog> but there is a really REALLY serious problem with uk jails
2019-09-07T17:56:47 < roomba> do you have uk jail experience you can share?
2019-09-07T17:56:57 < Mangy_Dog> ot going to comment
2019-09-07T17:56:59 < Mangy_Dog> not
2019-09-07T17:57:21 < Mangy_Dog> lets just say this... Suicide rates in UK prisons are at horrifically high levels
2019-09-07T17:57:47 < Mangy_Dog> the UK prison system is at 200-300% capacity 
2019-09-07T17:58:03 < Mangy_Dog> that means cells made for 1 or 2 people are filled with 3 or 4 people
2019-09-07T17:58:20 < Mangy_Dog> The EU law on prisons say cells are meant to be single ocupide
2019-09-07T17:58:25 < Mangy_Dog> unless requested to be doubled.
2019-09-07T17:59:03 < Mangy_Dog> prisons on a daily base break human rights laws, and in many of the worst places guards regularly beat up and assult prisons for the heck of it
2019-09-07T17:59:17 < roomba> that's nearly double the capacity of amerimutt prisons
2019-09-07T17:59:19 < Mangy_Dog> food is of a really poor quality
2019-09-07T17:59:29 < roomba> does UK have private prisons?
2019-09-07T17:59:34 < Mangy_Dog> with mailneutrision being a real problem too
2019-09-07T17:59:54 < Mangy_Dog> theres privately run prisons in the system but theyre often also really bad quality as well
2019-09-07T18:00:12 < Mangy_Dog> as theyre ran to turn a profit which means everything is cut and stripped back
2019-09-07T18:00:16 < roomba> yeah the private prisons often are worse
2019-09-07T18:00:27 < Mangy_Dog> there are one or two though that have been known to be decent
2019-09-07T18:00:43 < roomba> where the rich white collar people go :)
2019-09-07T18:01:04 < Mangy_Dog> malneutrition is an issue... where portions might be reasonable in spome places, the quality of the food is so poor people do not get anywhere close to the neutriants vets and minirals they need
2019-09-07T18:01:20 < Mangy_Dog> no the rich white collar people tend to get sent to a really cushy catD
2019-09-07T18:01:20 < roomba> yes this is very true
2019-09-07T18:01:22 < Mangy_Dog> like i say really quick
2019-09-07T18:01:26 < Mangy_Dog> within days of being put into the system
2019-09-07T18:01:41 < Mangy_Dog> when you have waiting lists going back sevveral years for the normal prisoner trying to get to catd
2019-09-07T18:01:45 < roomba> michelle obama really messed up the prison food here
2019-09-07T18:01:49 < Mangy_Dog> and to get to cat d you have to do a parole hearing
2019-09-07T18:02:11 < Mangy_Dog> but MPs seem to some how get through that aprt of the system really quick
2019-09-07T18:02:11 < roomba> i remember when i first got transferred to the prison where i spent most of my time
2019-09-07T18:02:35 < roomba> the cafeteria was like a god damn restaurant with a salad bar and everything
2019-09-07T18:02:45 < Mangy_Dog> i will say this... id still rather go to a UK prison than an american :p
2019-09-07T18:02:57 < Mangy_Dog> though if i had a choice id go to a scandinavian prison
2019-09-07T18:03:06 < Mangy_Dog> denmark sweeden holland
2019-09-07T18:03:18 < Mangy_Dog> they have the worlds highest quality prisons
2019-09-07T18:03:21 < roomba> then they changed the food system in the prisons (and schools) to a national standard
2019-09-07T18:03:31 < roomba> and the quality of food went to total shit overnight
2019-09-07T18:03:34 < Mangy_Dog> they actualy focus on rehabilitation and not punishment
2019-09-07T18:03:36 < roomba> no more salad bar
2019-09-07T18:04:03 < roomba> and now the only thing that isn't highly processed junkfood is rotten apples and oranges
2019-09-07T18:04:16 < Mangy_Dog> thats sad to hear i rather like her
2019-09-07T18:04:21 < Mangy_Dog> i dont think thats what she set out to do
2019-09-07T18:04:36 < roomba> who. michelle?
2019-09-07T18:04:38 < roomba> no
2019-09-07T18:04:38 < Mangy_Dog> sounds like she wanted to make sure everyone meets a good standard just no one told her that the bar was set so low
2019-09-07T18:04:39 < Mangy_Dog> yeah
2019-09-07T18:04:49 < roomba> i think she genuinely wanted to improve the health and nutrition
2019-09-07T18:04:59 < Mangy_Dog> yeah
2019-09-07T18:05:02 < roomba> but as most things in 'murica... capitalism baby!
2019-09-07T18:05:11 < roomba> the companies that won the contracts are all junkfood companies.
2019-09-07T18:05:17 < Mangy_Dog> nods
2019-09-07T18:05:35 < roomba> so like... while they're technically following the standards she set in place
2019-09-07T18:05:46 < roomba> the reality is - it's all complete garbage
2019-09-07T18:05:51 < Mangy_Dog> yeah
2019-09-07T18:06:13 < roomba> i never even know shit like "buffaloaf" existed. which was basically like this buffalo wings hot sauce infused mystery meat they called "steak"
2019-09-07T18:06:29 < Mangy_Dog> eeesh
2019-09-07T18:06:36 < roomba> i worked in the prison warehouse for a while
2019-09-07T18:06:47 < roomba> and we had a huge freezer where all the frozen stuff would come in
2019-09-07T18:06:58 < roomba> we got a whole semi truck of chicken one time.
2019-09-07T18:07:21 < roomba> every single box was marked with a label that said "test product - not for human consumption" on it
2019-09-07T18:07:29 < Mangy_Dog> fuck
2019-09-07T18:07:33 < roomba> because ... government's gotta save money right?
2019-09-07T18:07:48 < roomba> so me and some of teh other dudes were like "yo this is not good. we're not gonna eat this"
2019-09-07T18:08:24 < Mangy_Dog> did you even get to speak to the governer about it?
2019-09-07T18:08:24 < roomba> they gave us a bucket full of sharpie markers and made us go into the freezer and try to tear off the labels or cover them up
2019-09-07T18:08:26 < roomba> rofl
2019-09-07T18:08:43 < roomba> and we ate that shit
2019-09-07T18:08:49 < Mangy_Dog> :(
2019-09-07T18:09:06 < Mangy_Dog> i dont think they would be allowed to go that far here
2019-09-07T18:09:13 < Mangy_Dog> would be a massive scandle
2019-09-07T18:09:18 < BrainDamage> you should've saved one
2019-09-07T18:09:25 < roomba> that's the thing you don't understand about how prison systems work rofl
2019-09-07T18:09:33 < Mangy_Dog> nonono I do
2019-09-07T18:09:38 < roomba> there is A LOT of crazy stuff like that that goes on.
2019-09-07T18:09:38 < Mangy_Dog> please trust me on this one i do
2019-09-07T18:09:39 < Mangy_Dog> at least here
2019-09-07T18:09:42 < Mangy_Dog> yeah i know
2019-09-07T18:09:44 < roomba> and the majority of it goes unreported
2019-09-07T18:09:55 < Mangy_Dog> the law doesnt exsist inside unless a prisoner does something wrong inside
2019-09-07T18:10:03 < roomba> because the public doesn't care about people in prisons unless it's THEIR family members in the prison.
2019-09-07T18:10:18 < Mangy_Dog> but i do also know theres still enough "decent" staff members in teh system who whistle blow when things go to shit
2019-09-07T18:10:26 < Mangy_Dog> and thats true to
2019-09-07T18:10:38 < roomba> yea
2019-09-07T18:10:43 < roomba> this rcazy thing happened when i was in there
2019-09-07T18:10:59 < Mangy_Dog> honestly though, if food was being fed to prisons thats clearly not even fit for human consumption... that would get out
2019-09-07T18:11:03 < roomba> in the warehouse, we had this seperate locked cage with all kinds of important records
2019-09-07T18:11:14 < roomba> like health records and stuff
2019-09-07T18:11:27 < roomba> they were required to keep them for a number of years and then destroy them.
2019-09-07T18:11:34 < Mangy_Dog> the regular assults on prisons from staff never gets out thats covered up and if a report is written up on it... Its usually the story that the prisoner was violent and started it
2019-09-07T18:11:41 < Mangy_Dog> even if said prisoner doesnt have any history of violence
2019-09-07T18:11:59 < roomba> so every year, we have to go in there and grab all these boxes of records... and it's ultra-controlled. multiple guards watching us.
2019-09-07T18:12:37 < roomba> so we're in there. it's me and one other inmate and like 4 guards supervising us take all these boxes and put them on pallets to get sent to the place that destroys them.
2019-09-07T18:12:46 < Mangy_Dog> if its medical records youd think medical staff would be handlign the destruction of confidential data
2019-09-07T18:12:58 < roomba> the other inmate dropped a box full of records right on my hand and broke my finger
2019-09-07T18:13:08 < roomba> was an accident
2019-09-07T18:13:15 < Mangy_Dog> nods
2019-09-07T18:13:24 < roomba> so i ended up going to the prison doctor
2019-09-07T18:13:30 < roomba> which is actually better than the US healthcare system rofl
2019-09-07T18:13:52 < Mangy_Dog> again depends on the prison but most Uk prisons have NHS staff
2019-09-07T18:14:03 < roomba> i remember screaming in pain and like "shit i think it's broken" and the guards were like "alright lock it up lets go! you gotta go to medical!"
2019-09-07T18:14:09 < Mangy_Dog> who are usually respectful and decent people
2019-09-07T18:14:24 < roomba> so i went to medical and got xrays and they gave me treatment for it and put me out of work for 2 weeks
2019-09-07T18:14:52 < roomba> which was awesome. i just hung out and watched tv because they wouldn't let me do anything else.
2019-09-07T18:15:08 < roomba> 2 weeks later i return to work
2019-09-07T18:15:31 < roomba> i'm chilling at the desk because my hand wasn't healed yet
2019-09-07T18:15:44 < roomba> and SIS raids us
2019-09-07T18:15:53 < roomba> SIS = special investigatory supervisors
2019-09-07T18:15:54 < Mangy_Dog> SIS?
2019-09-07T18:15:56 < Mangy_Dog> ah
2019-09-07T18:16:08 < roomba> they're like an internal prison FBI
2019-09-07T18:16:17 < Mangy_Dog> noids
2019-09-07T18:16:19 < Mangy_Dog> nods
2019-09-07T18:16:29 < roomba> rounded us all up and threw us in "the hole"
2019-09-07T18:16:46 < roomba> no phone calls. no mail.
2019-09-07T18:17:02 < roomba> and no explaination as to why we are in there. and said "you're all getting transferred to maximum security"
2019-09-07T18:17:15 < Mangy_Dog> D:
2019-09-07T18:17:28 < roomba> after like 3 weeks of sitting in there with no contact with anyone
2019-09-07T18:17:39 < roomba> the grab me and take me to an office and a bunch of SIS officers are in there
2019-09-07T18:17:48 < roomba> and said they're charging me with new crimes
2019-09-07T18:18:13 < roomba> here's what happened
2019-09-07T18:18:15 < Mangy_Dog> D:
2019-09-07T18:18:38 < roomba> when that accident occured and i got sent to medical, the guards were flustered and weren't paying attention.
2019-09-07T18:19:06 < roomba> they left an entire pallet (wrapped in plastic) of sensitive medical records and employee records or something
2019-09-07T18:19:33 < Mangy_Dog> how could they logically come up with charging you or any other prisoner for the guards fuckup?
2019-09-07T18:19:46 < roomba> according to the SIS dudes, they said they did a search of the warehouse for contraband and they tore open those boxes of records
2019-09-07T18:20:03 -!- kakimir [575d220c@87-93-34-12.bb.dnainternet.fi] has joined ##stm32
2019-09-07T18:20:09 < roomba> and one of the guards found a bunch of documents containing SSNs and other person info on prison staff
2019-09-07T18:20:29 < roomba> being that i was the only one in the warehouse charged with ID theft
2019-09-07T18:20:58 < roomba> they decided to round up all of the warehouse inmates and get them to turn on me and say i got into the records
2019-09-07T18:21:16 < Mangy_Dog> again how could they logically come up with the idea that you or any othe rprisoner was at fault... Your no the one in power they are.... They control everything youre just a flunky... The only ones who should be getting any bollocking is the staff
2019-09-07T18:21:26 < roomba> that's the thing
2019-09-07T18:21:27 < Mangy_Dog> like how would you get private info like that unless its given to you
2019-09-07T18:21:40 < roomba> the guard that tore open the boxes wasn't gonna lose her job over it
2019-09-07T18:21:47 < roomba> so they decided to frame up inmates
2019-09-07T18:22:19 < roomba> the only thing that saved me was 1. i was literally not there and there was a paper trail to prove it. and 2. i made a very crucial phone call when they let me out of the hole.
2019-09-07T18:22:24 < Mangy_Dog> so were you given extr time?
2019-09-07T18:22:29 < roomba> i called a news reporter :)
2019-09-07T18:22:32 < roomba> it was hilarious too because
2019-09-07T18:22:36 < Mangy_Dog> ahh
2019-09-07T18:22:47 < roomba> i'm mid-conversation with the reporter and the phone goes dead
2019-09-07T18:22:55 < Mangy_Dog> they were listning in
2019-09-07T18:23:01 < Mangy_Dog> didnt like what they heard?
2019-09-07T18:23:02 < roomba> and then they called me over the prison loudspeakers to the administration building like 2 seconds later
2019-09-07T18:23:05 < roomba> and they sounded ANGRY lol
2019-09-07T18:23:28 < roomba> so i go up there... and there's this SIS guy who was actualy cool.
2019-09-07T18:24:17 < roomba> and he's like "listen... one of the guards fucked up and they tried to pin it on you. and you breaking your finger saved your ass. we'll drop all of this as long as you agree not to talk to any more reporters."
2019-09-07T18:24:19 < roomba> and that was that.
2019-09-07T18:24:47 < Mangy_Dog> i dont know if i could have accepted that
2019-09-07T18:24:48 < Mangy_Dog> tbh
2019-09-07T18:24:58 < roomba> nah it made sense to me at the time
2019-09-07T18:25:01 < roomba> like i wasn't gonna keep pushing it.
2019-09-07T18:25:08 < roomba> they never fucked with me after that.
2019-09-07T18:25:12 < Mangy_Dog> nods
2019-09-07T18:25:24 < roomba> the prison system is legit scared of bad publicity and scandals
2019-09-07T18:25:36 < roomba> especially if you're a high profile inmate
2019-09-07T18:25:42 < roomba> which i was at the time
2019-09-07T18:25:47 < Mangy_Dog> nods
2019-09-07T18:25:53 < roomba> like national headlines repeatedly. covers of magazines.
2019-09-07T18:25:59 < Mangy_Dog> fun
2019-09-07T18:27:36 < roomba> like 2 years later i ended up in the hole again for punching a microwave oven
2019-09-07T18:27:49 < Mangy_Dog> :(
2019-09-07T18:27:51 < roomba> did you know a prison microwave oven costs $1500 ?
2019-09-07T18:27:53 < roomba> lol
2019-09-07T18:27:58 < Mangy_Dog> cost+
2019-09-07T18:28:30 < roomba> they made me chop down a forrest with a weed whacker all summer for that
2019-09-07T18:28:35 < roomba> not even joking
2019-09-07T18:28:42 < Mangy_Dog> :<
2019-09-07T18:28:43 < roomba> i went through 3 weedwhackers. they caught on fire.
2019-09-07T18:29:05 < roomba> anything that wasn't a tree... cut it down.
2019-09-07T18:29:37 < roomba> then i crashed a truck
2019-09-07T18:29:48 < roomba> but didn't have to pay for that. they just gave me another one.
2019-09-07T18:30:15 < roomba> then i stole a john deere tractor and welded a recliner to it.
2019-09-07T18:30:21 < roomba> and they just laughed.
2019-09-07T18:30:31 < roomba> so you see... prisons don't make any sense.
2019-09-07T18:30:49 < Mangy_Dog> well in the Uk prisons wouldnt get a tractor :p
2019-09-07T18:30:51 < Mangy_Dog> not even in cadD
2019-09-07T18:31:23 < Mangy_Dog> catD is open prions, minimal security... Some dont even have perimiter fences.
2019-09-07T18:31:41 < roomba> that sounds like the same minimum security stuff in the US
2019-09-07T18:31:44 < roomba> no fences
2019-09-07T18:31:57 < Mangy_Dog> more like a controlled village
2019-09-07T18:32:06 < roomba> yes exactly like that.
2019-09-07T18:32:21 < roomba> except where i was, if your job entailed driving a vehicle, you drove a vehicle.
2019-09-07T18:32:29 < Mangy_Dog> nods
2019-09-07T18:32:54 < roomba> they figure if you worked your way down to minimum security, you're not going to jeapordize that "privilege" by doing something stupid.
2019-09-07T18:32:58 < roomba> so they give you a lot of slack
2019-09-07T18:36:07 < Mangy_Dog> but this is what i mean... very very few prisons get catD... heck there are tons of CatD people in CatC because there isnt the space... and you get a MP who goes inside and jumps the queue without even having to go infront of a parol panel and explain why they have changed there life around and can be trusted to go to catD

2019-09-07T18:37:28 < roomba> yea and then they piss off other inmates because they got special treatment

2019-09-07T18:37:49 < Mangy_Dog> well yes and no
2019-09-07T18:38:01 < Mangy_Dog> piss everyone off indeed because of the shear cheek of it
2019-09-07T18:38:11 < Mangy_Dog> and no they dont make any friends
2019-09-07T18:38:21 < Mangy_Dog> but usually no one would do anything because they dont want to get fucked over
2019-09-07T18:38:30 < roomba> yea exactly. that's how it is at the minimums.
2019-09-07T18:38:41 < roomba> so it's all mind games.

2019-09-07T18:45:11 < Mangy_Dog> in fairness this part of the UK doesnt have many buses :p
2019-09-07T18:45:39 < roomba> lol ok so bus therapy is when they transfer you around from prison to prison - usually USP (the highest step before ADMAX - administrative max)
2019-09-07T18:45:47 < Laurenceb_> ah
2019-09-07T18:45:52 < roomba> the idea is to make it so you're never settled - constantly on the move.
2019-09-07T18:45:59 < roomba> it totally lobotimizes you
2019-09-07T18:46:13 < Mangy_Dog> ahhh that would be illegal here
2019-09-07T18:46:20 < Mangy_Dog> pretty sure that goes under cruel and unusual
2019-09-07T18:46:22 < roomba> yea they did that to me for 2 yrs lol
2019-09-07T18:46:26 < Mangy_Dog> :(
2019-09-07T18:46:40 < roomba> and like
2019-09-07T18:46:45 < roomba> you're never in GP (general population)
2019-09-07T18:46:48 < Mangy_Dog> doesnt mean you wont get transfered for reasons
2019-09-07T18:47:04 < roomba> you're spending all of your days in holding cells with like 50 other people
2019-09-07T18:47:10 < roomba> or in solitary confinement cells
2019-09-07T18:47:16 < Mangy_Dog> but usually once youre in your main prison, youll usualy spend the rest of your sentence there
2019-09-07T18:47:25 < roomba> all with 23 & 1 lockdown
2019-09-07T18:47:31 < Mangy_Dog> fun :(
2019-09-07T18:47:40 < roomba> atlanta was the worst i went through there twice
2019-09-07T18:48:14 < Mangy_Dog> :(
2019-09-07T18:49:01 < bitmask> woman in india gives birth to twins at age of 73.  thats just cruel to the children
2019-09-07T18:49:31 < Mangy_Dog> yeah is aw that and thought that was wrong
2019-09-07T18:49:50 < bitmask> I think the father had a stroke the next day too
2019-09-07T18:51:35 < Laurenceb_> pedo
2019-09-07T18:51:54 < Mangy_Dog> D:
2019-09-07T18:52:10 < Mangy_Dog> @ the father that is
2019-09-07T18:54:02 < roomba> shit those kids will be fine
2019-09-07T18:54:17 < roomba> murica kids have no parents most of the time and they turn out alright

2019-09-07T21:02:57 < bitmask> how does exercising work? If you are eating healthy and do just sit ups will your body reduce the fat stores around your abs most? or do you just build up muscle in your abs and the weight loss isn't location specific
2019-09-07T21:05:28 < Cracki> if you want to get rid of fat, you'll have to starve (i.e. energy in < energy out)
2019-09-07T21:05:44 < Cracki> and exercise WHILE doing that makes sure the body doesn't eat muscle instead of fat
2019-09-07T21:05:56 < Cracki> because muscle is easier to "eat up" than fat
2019-09-07T21:06:23 < bitmask> didn't answer the question :P
2019-09-07T21:06:24 < Cracki> fat loss isn't location specific. spot training only trains muscle, doesn't consume fat.
2019-09-07T21:06:33 < bitmask> ok
2019-09-07T21:06:43 < Cracki> doesn't consume fat in specific regions
2019-09-07T21:08:00 < Cracki> so yes, it's possible and common to have a sixpack behind a belly
2019-09-07T21:08:24 < Cracki> the cheapest way to "get" a sixpack is to burn off the fat (and exercise moderately to maintain muscles)
2019-09-07T21:08:44 < Cracki> it's inside you already
2019-09-07T21:09:50 < Cracki> fat deposits store all kinds of waste and drugs and toxins too, so when you starve, all that stuff comes out again
2019-09-07T21:10:16 < jadew> yeah, my PT said the same, fat burning isn't region specific, but there are exercises that help with fat burning
2019-09-07T21:10:17 < Cracki> that's what happens to people in hospitals on their meager meals
2019-09-07T21:10:30 < Cracki> "help with"? do tell
2019-09-07T21:10:34 < jadew> generally speaking most exercises do, but combinations are better
2019-09-07T21:10:44 < jadew> for example, doing crunches while doing something else too
2019-09-07T21:10:50 < qyx> karlp: do you happen to have a drawing with dimensions of the pcie thing? just for cross reference
2019-09-07T21:11:04 < jadew> so basically, something that's using multiple sections of muscles
2019-09-07T21:11:23 < bitmask> I want a rowing machine, my dad used to have one, those things are great for the whole body
2019-09-07T21:12:00 < Steffanx> ok
2019-09-07T21:12:13 < jadew> he was also of the opinion that losing weight is best done by changing your eating habits
2019-09-07T21:12:14 < Cracki> sounds easier and safer than deadlifts
2019-09-07T21:12:24 < jadew> so the exercises are just an extra, like Cracki says
2019-09-07T21:12:47 < Cracki> necessary extra, or else you end up with fat and NO muscle
2019-09-07T21:12:56 < jadew> didn't know that
2019-09-07T21:13:05 < Cracki> that's what everyone keeps saying anyway
2019-09-07T21:13:10 < bitmask> I'm good with my body weight, I just have a small belly now which I want to improve
2019-09-07T21:13:22 < jadew> the only time when I managed to lose weight consciously, I biked about 3 times per week (to the gym) in a very alert fashion
2019-09-07T21:13:25 < Cracki> aha! https://en.wikipedia.org/wiki/Starvation_response
2019-09-07T21:13:34 < jadew> then I did the training until I was close to passing out
2019-09-07T21:13:37 < Cracki> yes, glycogen is gone first, but that's the very first thing
2019-09-07T21:14:01 < jadew> took 6 months to lose ~8 kg
2019-09-07T21:14:04 < Cracki> yeah energy output > energy input
2019-09-07T21:14:10 < Cracki> either eat less or do more or both
2019-09-07T21:14:11 < jadew> and gained 200 g of muscle
2019-09-07T21:14:21 < jadew> so... not impressive
2019-09-07T21:14:35 < bitmask> I dont really want to lose weight, juts redistribute, unfortunately thats no so easy
2019-09-07T21:14:47 < jadew> bitmask, getting a beer belly?
2019-09-07T21:14:53 < Cracki> liposuction is tricky for men with all their visceral fat
2019-09-07T21:15:24 < bitmask> a little bit.  I'm just used to being stick thin my whole life, now I actually have a bit of fat built up.  Maybe just doing crunches will help tighten things up
2019-09-07T21:15:38 < jadew> bitmask, yeah, I'm the same
2019-09-07T21:15:49 < jadew> quitting sweets helps a lot
2019-09-07T21:16:24 < jadew> I used to be able to live on chocolate bars for days
2019-09-07T21:16:31 < bitmask> I never had a sweet tooth until a couple years ago, even as a kid I never ate deserts
2019-09-07T21:16:38 < bitmask> weird how things change
2019-09-07T21:16:45 < jadew> sounds exactly like me

2019-09-07T21:43:31 < Cracki> wp article reads like it happens kinda simultaneously. bone mineral density also decreases, but not getting brittle or anything. sounds more like "I don't need all this muscle to move all this fat"
2019-09-07T21:43:54 < Cracki> also muscles store glycogen iirc

2019-09-07T21:54:11 < jadew> I found what I was looking for, but they cost more than I'm planning to sell this thing for

2019-09-07T21:57:54 < jadew> invzim, I'm looking for an N-type to SMA male connector, stainless steel
2019-09-07T21:58:23 < invzim> never used those, so haven't gone through the pain :)
2019-09-07T21:58:48 < invzim> ususal suspects like lcsc didn't have it?
2019-09-07T21:59:03 < jadew> best I found was $100 :/
2019-09-07T21:59:22 < jadew> invzim, I don't think I checked them for this particular one
2019-09-07T21:59:28 < jadew> I'll have to give them another try
2019-09-07T21:59:54 < qyx> oh coax connectors
2019-09-07T22:00:10 < qyx> if you are a connector super pro now
2019-09-07T22:00:18 < invzim> u.fl not an option?
2019-09-07T22:00:19 < qyx> are there any with IP rating?
2019-09-07T22:00:29 < jadew> qyx, lots
2019-09-07T22:00:34 < qyx> I mean, smaller than N
2019-09-07T22:00:37 < qyx> SMA-like
2019-09-07T22:00:47 < qyx> for rubber antennas
2019-09-07T22:01:00 < jadew> yeah, there are bulkhead ones with o-rings

2019-09-07T23:56:41 < BrainDamage> having plenty of ram helps

2019-09-07T23:57:26 < BrainDamage> and if an update crap things up, I can just roll back
2019-09-07T23:57:28 < roomba> there is no need for 32GB yet. 16GB is about standard if you want to run today's javashit.
2019-09-07T23:57:49 < kakimir> 16GB costs nothing much
2019-09-07T23:57:55 < kakimir> as you have 4 slots
2019-09-07T23:58:10 < kakimir> if you have 2 it's wayy more expensive
2019-09-07T23:58:34 < kakimir> and 32GB with 2 slots yeah even more
2019-09-07T23:58:36 < Steffanx> Lies.
2019-09-07T23:58:57 < roomba> though definitely get 32GB if you plan on using slack AND actually working.

2019-09-08T00:09:34 < jadew> kakimir, yeah, I used to use when doing some tests on a piece of software, which generated thousands of files
2019-09-08T00:14:46  * catphish has chosen a replacement toy https://i.ebayimg.com/images/g/rN0AAOSwTUZdUmR8/s-l1600.jpg
2019-09-08T00:18:22 < Steffanx>  Fancy green.
2019-09-08T00:18:47 < catphish> i like green, same as my old one
2019-09-08T00:19:53 < kakimir> what happens to broken toy?
2019-09-08T00:20:01 < kakimir> lemme guess
2019-09-08T00:20:08 < kakimir> carburetor didn't fix it?
2019-09-08T00:20:53 < ThatDamnRanga> Anyone have any experience with the MCP256x CAN transceivers?
2019-09-08T00:20:57 < catphish> kakimir: exactly that, i totally rebuilt it with new float valve pins, it made absolutely zero difference (apart from maybe idling a bit smoother)
2019-09-08T00:21:19 < ThatDamnRanga> I'm having a very odd issue.... Powering on the chip, by itself, with no other components connected..... results in it getting very hot
2019-09-08T00:21:21 < kakimir> valve clearances then
2019-09-08T00:21:23 < catphish> kakimir: then i decided i was sick of trying to guess at fixes, so i sold it
2019-09-08T00:21:36 < kakimir> sold already?
2019-09-08T00:21:41 < kakimir> that's quick
2019-09-08T00:21:56 < catphish> kakimir: IMO it's almost certainly valve clearances, but that's too much of a job for me, and yes, advertised and sold yesterday
2019-09-08T00:22:06 < catphish> (giveaway price)
2019-09-08T00:22:16 < kakimir> when replacement toy?
2019-09-08T00:23:40 < catphish> seller is on holiday til next weeekend, made a provisional offer on it, will go see it (and hopefully finalize next sunday / mondday)
2019-09-08T00:24:15 < catphish> will have to fill my time with writing code til then :)
2019-09-08T00:25:04 < catphish> and staring lovingly at the photo
2019-09-08T00:25:57 < kakimir> how much?

2019-09-08T00:46:39 < roomba> i was at walmart today and saw a huge truck with rebel flags
2019-09-08T00:46:58 < Laurenceb_> based
2019-09-08T00:46:59 < roomba> this is very common
2019-09-08T00:47:15 < Laurenceb_> my brother has rebel flags and nra hat on his faceberg
2019-09-08T00:47:19 < catphish> which rebel flag? confederate?
2019-09-08T00:47:24 < roomba> yea confederate
2019-09-08T00:47:27 < roomba> and when they got out
2019-09-08T00:47:27 < Laurenceb_> now my dad has blocked him
2019-09-08T00:47:44 < catphish> lol
2019-09-08T00:47:44 < roomba> it was like this 500lb white lady with her super skinny black bf
2019-09-08T00:47:54 < Laurenceb_> lawl
2019-09-08T00:48:08 < Laurenceb_> black guy got cucked
2019-09-08T00:48:12 < roomba> some cans of steel reserve fell out when she opened the door
2019-09-08T00:48:16 < catphish> i'm sure my parents have one of those flags
2019-09-08T00:48:24 < catphish> but i don't think it really means anything here
2019-09-08T00:48:37 < roomba> it's moments like that i wish i still carried a smartphone
2019-09-08T00:48:48 < roomba> because that shit right there was People of Walmart for sure
2019-09-08T00:53:26 < Laurenceb_> I think my stepmum is a qtard
2019-09-08T00:53:39 < Laurenceb_> I'm not going to visit her faceberg tho
2019-09-08T01:01:24 < catphish> my stepdad is cool, he's an electronics engineer :)
2019-09-08T01:01:52 < catphish> good marriage choice by my mum, i suspect young catphish encouraged this
2019-09-08T01:07:15 < roomba> it's very polarized here in my town
2019-09-08T01:07:40 < catphish> what is?
2019-09-08T01:07:40 < roomba> the majority of aged 40 and up are hardcore qtard magatard
2019-09-08T01:08:05 < roomba> and anyone under 40 is hardcore sjw
2019-09-08T01:08:14 < catphish> USA?
2019-09-08T01:08:16 < roomba> yea
2019-09-08T01:09:04 < catphish> yeah i've seen USA has crazy polalization, which IMO means people aren't looking at individual issues
2019-09-08T01:09:24 < roomba> yea that's the whole point of it.
2019-09-08T01:09:33 < catphish> because once you look at individual issues, you quickly find that you don't magically fit one of 2 sides
2019-09-08T01:10:23 < roomba> media tries to keep pushing us to the extremes so we're at eachother's throats and not paying attention to real issues.
2019-09-08T01:10:25 < catphish> seems like a scary tribalistic model that i hope never forms here in the UK
2019-09-08T01:10:29 < ThatDamnRanga> Turns out that the MCP2561 is... reasonably tolerant to having its supply and ground inverted
2019-09-08T01:10:47 < roomba> ThatDamnRanga: for how long?
2019-09-08T01:10:56 < ThatDamnRanga> a few seconds at a time
2019-09-08T01:11:23 < catphish> things got churned up here because of brexit, its totally turned things around because suddenly everyone is divided on a specific issue, and it doesn't fit our existing opposing political parties, it's literally torn apart those parties
2019-09-08T01:11:26 < roomba> hmm i wonder if that is a requirement
2019-09-08T01:11:26 < ThatDamnRanga> I'm fairly certain I cooked the two on the soldered board I made, before I switched to breadboard, though. Yes, I am that blonde sometimes -_-
2019-09-08T01:11:40 < ThatDamnRanga> (one of them emitted the teltale popping noise)
2019-09-08T01:11:55 < roomba> catphish: haha welcome to the club then :)
2019-09-08T01:12:05 < catphish> at the same time, it's almost as dumb to focus on one specific issue as it is to focus on party affilitatiokn
2019-09-08T01:12:13 < catphish> roomba: indeed
2019-09-08T01:12:25 < roomba> as long as we're infighting over pointless political things, we won't bother to fight against the real agendas being pushed.
2019-09-08T01:12:48 < roomba> i.e. global currency, global technocratic governance, global identity, etc.

2019-09-08T01:12:57 < qyx> such caps
2019-09-08T01:13:29 < roomba> looks like audiophile stuff
2019-09-08T01:13:31 < catphish> we've always been good in the UK (partly thanks to certain less biased media outlets) at focusing on issues that really matter, but that's falling apart recently
2019-09-08T01:13:38 < ThatDamnRanga> qyx, purely just a voltage stabiliser?
2019-09-08T01:14:03 < rajkosto> purely bullshit
2019-09-08T01:14:08 < ThatDamnRanga> I like that it's flippable between PCI and PCIe
2019-09-08T01:14:19 < ThatDamnRanga> well, yeah, of course it's BS, but audiophiles will buy it
2019-09-08T01:14:20 < rajkosto> PCI has a 5V rail PCI-E has a 3.3v rail
2019-09-08T01:14:23 < catphish> qyx: WTF? is that just something to help PSUs provide peak current?
2019-09-08T01:14:25 < rajkosto> none of it matters
2019-09-08T01:14:26 < roomba> if it's audiophile stuff, i bet those caps are $50 a piece and the traces are 24k gold - not just plated. all gold.
2019-09-08T01:14:36 < ThatDamnRanga> rajkosto, PCI has both 3.3 and 5
2019-09-08T01:14:40 < qyx> and all bullshit, yes
2019-09-08T01:14:52 < ThatDamnRanga> can't speak for PCIe
2019-09-08T01:15:05 < qyx> +12V too on pcie
2019-09-08T01:15:17 < catphish> that does seem like pure bullshit, who's even running analog interfaces in PCs
2019-09-08T01:15:21 < rajkosto> tons of capacitors like this wont do shit
2019-09-08T01:15:27 < rajkosto> when they are connected via a trace on a mobo
2019-09-08T01:15:32 < rajkosto> through a card edge connector
2019-09-08T01:15:40 < Laurenceb_> I've blown an stm32 in half before
2019-09-08T01:15:44 < ThatDamnRanga> catphish, huge amounts of media production involves PCI/PCIe cards these days
2019-09-08T01:15:45 < Laurenceb_> surprisingly explosive
2019-09-08T01:15:52 < rajkosto> even newish psus providing "in wire capacitors" is better than this
2019-09-08T01:15:54 < catphish> ThatDamnRanga: surely for serious pro audio people are using external ADC/DAC hardware
2019-09-08T01:16:14 < ThatDamnRanga> catphish, actually, other way around. the pros tend to use internal cards, the less-pros tend to use USB gear
2019-09-08T01:16:25 < ThatDamnRanga> it's a bandwidth thing
2019-09-08T01:17:12 < BrainDamage> for audio it's absolutely not a problem of bandwith, just that usb isochron transfer mode is shit
2019-09-08T01:17:20 < catphish> ThatDamnRanga: i find that hard to believe, seems mad to use anything but ADAT
2019-09-08T01:17:52 < catphish> you can have ADAT on a PCIe card, but the analog is still external in a rack
2019-09-08T01:17:52 < BrainDamage> the reason why the external audio cards were so popular is simply on the belief that the pc internals are noisy
2019-09-08T01:18:06 < roomba> https://www.amazon.com/AudioQuest-Diamond-feet-Braided-Cable/dp/B003CT08E4
2019-09-08T01:18:14 < ThatDamnRanga> BrainDamage, and in fairness, if the card isn't built right... they are...
2019-09-08T01:18:26 < catphish> lmao i assume nobody has ever bought that
2019-09-08T01:18:32 < ThatDamnRanga> (And if the PSU is not high enough quality, or the MB's filtering is rubbish, etc)
2019-09-08T01:18:45 < rajkosto> "I was using internal USB card filter for months and value for the money is the best on the market. It has long brake in time 1-2 weeks but after that is quite impressiv"
2019-09-08T01:18:48 < catphish> if youre not using ADAT, use ADAT :)
2019-09-08T01:18:52 < rajkosto> break in time for capacitors ;)

2019-09-08T01:21:58 < catphish> ThatDamnRanga: interestingly that has both analog and ADAT
2019-09-08T01:23:07 < ThatDamnRanga> This shit is well out of my budget lol. I run a well-filtered PCIe sound card, and a couple external interfaces
2019-09-08T01:23:11 < catphish> but only one analog IO, ADAT supports 8 channels, so i can't imagine many people are using the analog IO, i mean who has a studio with just one channel
2019-09-08T01:24:18 < ThatDamnRanga> I see two channels?
2019-09-08T01:24:36 < BrainDamage> even two channels is quite underwhelming
2019-09-08T01:25:02 < catphish> ThatDamnRanga: you're right, stereo, 2 channels
2019-09-08T01:25:04 < ThatDamnRanga> And I mistakenly believed you meant actual tapes, not the optical interface 
2019-09-08T01:25:29 < BrainDamage> those are just DAT without the initial A
2019-09-08T01:25:58 < catphish> lol don't think ADAT and DAT are related :)
2019-09-08T01:26:10 < catphish> ADAT is 8 channel optical audio
2019-09-08T01:26:34 < BrainDamage> actually they are
2019-09-08T01:26:45 < BrainDamage> ADAT was the standard from alesis to wire up DAT
2019-09-08T01:26:47 < ThatDamnRanga> Interestingly, they're very closely related
2019-09-08T01:26:54 < catphish> interesting
2019-09-08T01:26:57 < BrainDamage> but the name stuck
2019-09-08T01:27:00 < ThatDamnRanga> lightpipe is the 'cut out the tape in the middle' evolution
2019-09-08T01:27:07 < catphish> is DAT used for digital audio recording?
2019-09-08T01:27:13 < BrainDamage> it used to be
2019-09-08T01:27:17 < ThatDamnRanga> https://en.wikipedia.org/wiki/ADAT 
2019-09-08T01:27:21 < BrainDamage> DAT stands for digital audio tape
2019-09-08T01:27:32 < catphish> by ADAT, i pretty much always mean lightpipe
2019-09-08T01:27:44 < catphish> never really considered its history
2019-09-08T01:27:52 < ThatDamnRanga> catphish, that's an effective way to confuse a lot of people :P
2019-09-08T01:30:13 < catphish> i guess if one has spare PCIe slots, might as well fill them with capacitors to help the power supply :)
2019-09-08T01:30:16 < BrainDamage> minidisks were also somewhat common for portable high quality registration
2019-09-08T01:30:36 < BrainDamage> catphish: nah. you want your filtering as physically close possible to the user

2019-09-08T01:30:58 < BrainDamage> otherwise, the big loop of the circuit creates high inductance that disconnects the filter at higher freq
2019-09-08T01:31:16 < ThatDamnRanga> I'd rather the filters were on the card. after the regulators
2019-09-08T01:31:21 < BrainDamage> exactly
2019-09-08T01:31:35 < ThatDamnRanga> the idea of having a buttload of stray capacitance on the voltage feeds in my machine scares me
2019-09-08T01:31:53 < BrainDamage> also, you don't need an insane amount of capacity to filter effectively
2019-09-08T01:31:59 < catphish> i don't see how capacitance on power lines is ever a bad thing
2019-09-08T01:32:15 < BrainDamage> it can throw off the SMPS controller
2019-09-08T01:32:18 < ThatDamnRanga> catphish, it is when the load on said lines differs, and your rails de-energise or energise at different rates
2019-09-08T01:32:20 < roomba> word up! time for some CBD and djang rest framework. i'll get this damn stm32 lte hotspot working one way or another
2019-09-08T01:32:31 < BrainDamage> it adds latency on the output regulation
2019-09-08T01:32:39 < BrainDamage> which in turn makes control hard
2019-09-08T01:32:43 < ThatDamnRanga> you can end up with say, the +12v being completely drained, and the +3.3v still being at full power... then things can go pop
2019-09-08T01:32:52 < BrainDamage> the dcdc runs on a loop bandwith
2019-09-08T01:32:59 < ThatDamnRanga> also yes, that, latency is the enemy of PID based regulation
2019-09-08T01:33:18 < catphish> BrainDamage: interesting, i figured more capacitance just slowed down voltage  changes and made regulation easier
2019-09-08T01:33:34 < BrainDamage> it slows down changes, but it also makes control harder
2019-09-08T01:33:36 < ThatDamnRanga> catphish, it slows down the rise when the voltage is too low. It slows down the sink when it's too high
2019-09-08T01:33:58 < BrainDamage> the system is designed to work at a certain freq
2019-09-08T01:33:58 < ThatDamnRanga> it makes the creep away from the correct voltage take longer, but also makes it take just as much longer to get back where it's meant to be
2019-09-08T01:34:06 < ThatDamnRanga> and then suddenly you have overshoot
2019-09-08T01:34:13 < catphish> ThatDamnRanga: that's obviously true, but simularly, you have more time to prevent it getting too high in the first place
2019-09-08T01:34:20 < BrainDamage> also, those caps are connected again by a long line from the psu
2019-09-08T01:34:29 < BrainDamage> so you get all sort of bouncing effects
2019-09-08T01:34:31 < ThatDamnRanga> catphish, assumes the PID is tuned to /expect/ that though.
2019-09-08T01:34:35 < BrainDamage> due to inductance and resonance

2019-09-08T01:34:49 < catphish> BrainDamage: the inductance delay seems like more of a problem
2019-09-08T01:35:18 < BrainDamage> you can thow a smps out of spec by putting too much cap in the load
2019-09-08T01:35:26 < catphish> of course a power supply wants the capacitors as close as possible
2019-09-08T01:35:29 < BrainDamage> and have it enter loop instability
2019-09-08T01:35:56 < BrainDamage> remember that the caps won't sit at the correct voltage always
2019-09-08T01:36:12 < BrainDamage> so your reasoning 'it slows down things' assumes the caps are already at the correct voltage
2019-09-08T01:36:24 < BrainDamage> but the circuit has to turn on, there's also EM interference, etc
2019-09-08T01:36:25 < catphish> i was shocked recently when i realised that an 800W PC power supply is basically putting out 60+ amps on the 12V lines
2019-09-08T01:36:32 < BrainDamage> the regulator has to compensate for it
2019-09-08T01:36:34 < catphish> that's an insane amount of current
2019-09-08T01:36:56 < BrainDamage> most of the power is on the 3.3 and 5V rails
2019-09-08T01:37:05 < catphish> really?
2019-09-08T01:37:08 < BrainDamage> yes
2019-09-08T01:37:12 < ThatDamnRanga> catphish, just imagine the currents involved in a CPU that has a 120w TDP and runs at 1.1v
2019-09-08T01:37:15 < BrainDamage> which then gets downshifted to 1.2 or so near the psu
2019-09-08T01:37:26 < catphish> are you sure, because most graphics cards have a 12V power input
2019-09-08T01:37:38 < BrainDamage> look at the current specs
2019-09-08T01:37:57 < ThatDamnRanga> the 12v rail is mostly used to feed the peripherals, and provide a phase or two of the CPU's power
2019-09-08T01:39:14 < BrainDamage> tldr: sticking a bunch of caps won't necessarily do good
2019-09-08T01:39:24 < BrainDamage> and is likely to make things worse in that configuration
2019-09-08T01:40:01 < ThatDamnRanga> but that won't stop audiophiles buying it
2019-09-08T01:40:23 < ThatDamnRanga> the only thing I can think it /might/ help with, is crappy mainboards where you get bus noise audibly through the onboard audio codec
2019-09-08T01:49:24 < catphish> ThatDamnRanga: the idea of a single IC running at 1.2V 120W is terrifying
2019-09-08T01:49:57 < BrainDamage> catphish: a modern cpu has literally hundreds of supply and ground pins
2019-09-08T01:50:07 < ThatDamnRanga> there's ones that run higher. that's just a fairly common TDP
2019-09-08T01:50:22 < catphish> BrainDamage: makes sense
2019-09-08T01:50:31 < BrainDamage> to be able to distribute current and reduce inductance
2019-09-08T01:50:55 < karlp> qyx: am on holidays, i can give you wjat ive got when im back, should also be abke to verify if it all fits then
2019-09-08T01:51:33 < karlp> qyx: pci express electromechanical pdf is freely available though, if you want more refereneces
2019-09-08T01:54:13 < karlp> jpa-: well, didnt read all of it, but the credits were interspersed with cut scenes with mire story, and i had to let it all roll to get back to play the free ending
2019-09-08T01:55:10 < Cracki> 12V...
2019-09-08T01:55:12 < karlp> and then i saw the license stuff at the very end, and i find that interesting, how its presented and what theynuse, so i started paying more attention and saw nanopb
2019-09-08T01:55:18 < Cracki> cpus get 12v, gpus get 12v
2019-09-08T01:55:53 < ThatDamnRanga> the CPUs regulator gets 12v, the chip itself doesn't
2019-09-08T01:55:54 < Cracki> the pentium 4 has its own P4 connector to get 12v 16a
2019-09-08T01:56:00 < qyx> karlp: enjoy your holidays
2019-09-08T01:56:07 < Cracki> of course but the chip gets ~1v or whatever, nobody's debating that
2019-09-08T01:56:16 < qyx> I grabbed some molex drawings and compared
2019-09-08T01:56:18 < qyx> should be ok
2019-09-08T01:56:36 < Cracki> 3.3/5v supplies a bunch of stuff on the mainboard but most power out of today's psus comes through 12v
2019-09-08T01:58:29 < Cracki> when I used a normal atx psu to supply 12V 3-5A to some pwmed led strips, it whined at the pwm frequency (around 1500 hz)... is that still something that's ok to give a big bypass cap to?
2019-09-08T01:59:12 < Cracki> I realize what that talk about voltage control earlier implies: no overkill
2019-09-08T01:59:38 < karlp> qyx: so far so ggod. long day with the girls but in a lovely appartment in dubrovnik today
2019-09-08T02:01:23 < qyx> islandish sea not warm enough?
2019-09-08T02:01:41 < BrainDamage> yes, you can slap a mF or so
2019-09-08T02:02:15 < BrainDamage> dubrovnik is pretty nice, but it has been assaulted ever since they started filming GoT
2019-09-08T02:02:58 < karlp> split for anfew days nexy then to istria for a week with evem more family
2019-09-08T02:03:04 < BrainDamage> try also split
2019-09-08T02:03:04 < catphish> bi
2019-09-08T02:03:27 < BrainDamage> istria is not that good imo, too industrial
2019-09-08T02:04:12 < BrainDamage> rjieka especially is a chokepoint nightmare
2019-09-08T02:04:15 < karlp> weve got a jumbtron house and pool in the countryside nearnumag for the extended family, it will be fine :)

2019-09-08T13:55:05 < ThatDamnRanga> Something I've never been entirely sure about... for SWD, do I specifically need an ST-Link, or can I use any SWD-capable CMSIS-DAP device?
2019-09-08T13:58:11 < ThatDamnRanga> (I already have the ATMEL-ICE device, etc. Don't really wanna duplicate if I don't have to)
2019-09-08T14:03:15 < PaulFertser> ThatDamnRanga: for SWD you can use any SWD device, and even some device that can just bitbang.
2019-09-08T14:03:58 < PaulFertser> ThatDamnRanga: CMSIS-DAP should work with any SWD target.
2019-09-08T14:04:23 < PaulFertser> But stlinks are common as they come "for free" with nucleo boards.
2019-09-08T14:04:59 < ThatDamnRanga> yeah indeed, and as such I have two here. But they have a non-standard header for the programming
2019-09-08T14:05:24 < ThatDamnRanga> not a 5x2 or 7x2 1.27mm
2019-09-08T14:06:17 < ThatDamnRanga> though to be fair my production boards, I'll probably just use pads instead of a header :P
2019-09-08T14:06:28 < PaulFertser> SWD often needs just three wires so even using jumper wires is ok. Also, many people design their microcontroller boards with stlink connector in mind. 
2019-09-08T14:07:06 < PaulFertser> And it's not hard to make a suitable programming cable to attach standard cortex-m debug connector to an stlink.

2019-09-08T14:09:43 < PaulFertser> ThatDamnRanga: how "mass" is your production going to be?
2019-09-08T14:10:51 < ThatDamnRanga> Remains to be seen. Initial run will be 5-10 units max
2019-09-08T14:11:42 < ThatDamnRanga> Then we'll see what demand looks like
2019-09-08T14:14:13 < PaulFertser> ThatDamnRanga: imho it'd be enough to make through holes for regular pin header and instead of soldering when programming just push it and slightly angle, and it'd be enough for the few seconds an automatic flash+verify operation will take...
2019-09-08T14:18:13 < ThatDamnRanga> Mmm, or use pogos, there's enough meat around the outside of the holes normally to make a good circuit

2019-09-08T14:25:59 < Mangy_Dog> 0x80 and 81 are something else entirely

2019-09-08T14:59:43 < PaulFertser> Just checked, on my laptop I get "MSC SCAN 176" for VOLUMEUP, "MSC SCAN 174" for VOLUMEDOWN.
2019-09-08T15:00:30 < nuxil> 175 mute?
2019-09-08T15:03:20 < PaulFertser> I found "#define KEY_VOLUMEUP 0x80 // Keyboard Volume Up" for HID, but my laptop keyboard is integrated, PS/2, not USB HID.

2019-09-08T16:42:01 < dongs> why? i have a very strict 'need to know' policy on knowledge
2019-09-08T16:42:15 < dongs> and knowing old 'murican comics is quite low on the priorities list for me
2019-09-08T16:42:19 < Mangy_Dog> because it will help you get on in life and interact with... people
2019-09-08T16:42:30 < Mangy_Dog> its not just an old american comic
2019-09-08T16:42:39 < dongs> i can't think of any situation where knowing what the fuck a batman is would improve my quality of life

2019-09-08T16:43:25 < Mangy_Dog> but its still worth knowing about

2019-09-08T17:01:37 <@englishman> also is hip to such pop culture references such as Grendizer
2019-09-08T17:02:05 < Mangy_Dog> hiphoppop about linux feels.... uughhhhhhh vomit inducing.
2019-09-08T17:02:46 < Mangy_Dog> actually no dont know all about it... but! have seen a trailer here or there
2019-09-08T17:02:57 < Mangy_Dog> tbh i know fairly little about it
2019-09-08T17:03:08 < Mangy_Dog> other than it being a japanese anime
2019-09-08T17:03:31 < Mangy_Dog> oh and that theres a movie coming
2019-09-08T17:03:36 < nuxil> hiphop ? lol

2019-09-08T17:03:53 < nuxil> its pop dude
2019-09-08T17:03:57 < Mangy_Dog> its like really lite hiphop for the masses... pop
2019-09-08T17:04:19 < nuxil> u dont like linux??
2019-09-08T17:04:26 < Mangy_Dog> i dont not like it
2019-09-08T17:04:33 < nuxil> you suck :p

2019-09-08T17:04:47 < Mangy_Dog> its ok... i do :(
2019-09-08T17:05:57 < nuxil> why do you not like it?
2019-09-08T17:07:10 < Mangy_Dog> its sometimes an infuriating pain in the arse
2019-09-08T17:07:49 < Mangy_Dog> i know how to just about get around it and can follow guides but fekk i really am not a linux power user at all
2019-09-08T17:13:34 < kakimir> butt pain
2019-09-08T17:13:43 < kakimir> right in the hole?
2019-09-08T17:13:43 < Steffanx> is it bad?
2019-09-08T17:15:18 < Steffanx> is kakimir alright
2019-09-08T17:15:29 < kakimir> since when?
2019-09-08T17:15:54 < Steffanx> his first steps on this earth
2019-09-08T17:23:10 < nuxil> hmm. i have a issue i dont understand. i have this matrix keypad i have hooked up to my gpio header on my nucleo. if i run code "A" it works.. if i implement the keypad code into code "B" project. the resulting key is wrong. not sure what im doing wrong.
2019-09-08T17:23:11 < nuxil> https://i.gyazo.com/bbdb036bd3555dca54ba6f249eab796e.png
2019-09-08T17:23:40 < nuxil> code on the right send the right value over uart. while the code on the left does not work. ie. i press 1 on the pad and it send value 2 over uart
2019-09-08T17:24:04 < nuxil> my matrix_keypad code http://paste.debian.net/1099526/
2019-09-08T17:24:18 < nuxil> i wounder if there is some other settings i have forgooten.
2019-09-08T17:26:28 < fenugrec> nuxil, why are you enabling RCC clocks for *every column*
2019-09-08T17:26:48 < fenugrec> my bad, didn't see init before
2019-09-08T17:27:43 < nuxil> well i was going to put it at the top of the function only make it enable clocks once. but i havent gotten that far yet. 
2019-09-08T17:29:14 < fenugrec> nuxil, in your left project you don't have MX_GPIO_init ?
2019-09-08T17:30:04 < nuxil> nop.. i dont have any other gpio ports used. its setup in the matrix_keypad init functon.
2019-09-08T17:30:19 < fenugrec> ok

2019-09-08T17:31:20 < nuxil> was woundering if there could be something in system_stm32f4xx.c or stm32f4xx_it.c thats messes things up.
2019-09-08T17:31:55 < fenugrec> have you ascertained that your uart is actually setup identically in both cases, i.e. correct speed etc
2019-09-08T17:32:10 < fenugrec> send a dummy 0x55 at init maybe
2019-09-08T17:33:09 < nuxil> both are set to huart2.Init.BaudRate = 115200;
2019-09-08T17:33:48 < nuxil> will try and send a byte after init.
2019-09-08T17:35:42 < nuxil> hmm.. yea if i send a value before the while loop. i does send the correct value. this is strange. 
2019-09-08T17:36:46 < fenugrec> well you can rule out the uart, good
2019-09-08T17:37:26 < nuxil> anywho.. i'll deal with this later. time to do my duty as a citizen and go give my vote. there is an election here. voting polls just opened.

2019-09-09T02:16:26 < Laurenceb_>  /s
2019-09-09T02:16:40 < Laurenceb_> need to work out how to take the bumper off my stupid ford car
2019-09-09T02:16:45 < Laurenceb_> fix or repair daily
2019-09-09T02:17:20 < Laurenceb_> its fixed on using weird plastic coated rivets
2019-09-09T02:18:07 < Laurenceb_> I can drill them out but will need replacements from somewhere, unless I bodge regular rivets into the drilled out plastic cases
2019-09-09T02:18:16 < Laurenceb_> ford at work
2019-09-09T02:19:34 < Cracki> normal people pay for that

2019-09-09T02:21:36 < kakimir> well
2019-09-09T02:21:37 < Laurenceb_> then I need to fix the rust thats all over the subframe
2019-09-09T02:21:47 < kakimir> plastic rivets wont rot
2019-09-09T02:22:05 < Laurenceb_> yeah but there are standard parts to do this job
2019-09-09T02:22:13 < kakimir> btw. you can order them from ebay
2019-09-09T02:22:20 < Laurenceb_> oh cool, link?
2019-09-09T02:22:27 < kakimir> kinda right size and stuff
2019-09-09T02:22:38 < kakimir> I don't have link
2019-09-09T02:22:53 < Laurenceb_> I'll try google
2019-09-09T02:24:44 < Laurenceb_> looks like they are "large flange head" rivets, but the flange is plastic
2019-09-09T02:24:54 < Laurenceb_> guess I could prob just use aluminium
2019-09-09T02:25:22 < Laurenceb_> the ford ones seem to be steel center with glass fibre flange
2019-09-09T02:27:16 < Laurenceb_> I still need to try haxoring the ecu on this thing
2019-09-09T02:27:27 < Laurenceb_> then maybe it will have a good torque curve
2019-09-09T02:27:43 < Laurenceb_> and belch nox over everyone
2019-09-09T02:31:03 < Laurenceb_> at least I fixed the broken boot - the central locking had eaten a sliver of plastic off the plastic coated catch

2019-09-09T02:59:50 <@englishman> Laurenceb_: has jewK stopped using so much coal that electric vehicles are less of an environmental disaster there
2019-09-09T03:04:53 < Laurenceb_> maybe

2019-09-09T11:29:35 < nuxil> :D 
2019-09-09T11:31:16 < nuxil> In my SystemClock function  i have this line at the end.  if (HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_5) != HAL_OK) { Error_Handler(); }
2019-09-09T11:31:20 < nuxil> what is this FLASH_LATENCY_5 ???
2019-09-09T11:31:30 < nuxil> how is it calulated.

2019-09-09T11:31:59 < Ultrasauce> pay no heed to his deflection
2019-09-09T11:33:08 < PaulFertser> nuxil: you're supposed to select appropriate wait states for the flash based on how fast you clock the CPU core.
2019-09-09T11:34:19 < Steffanx> Wanna buy some, Ultrasauce  ;)

2019-09-09T11:36:17 < nuxil> PaulFertser, ok. but how do i know if need to use FLASH_LATENCY_1 or 5 based on my clock?? where do i look up info about this.
2019-09-09T11:37:00 < PaulFertser> nuxil: family reference manual

2019-09-09T11:37:18 < Steffanx> Muh stash: http://imgur.com/a/yufpkrc
2019-09-09T11:37:50 < jpa-> you can go 1 latency step lower to speed up your code a bit and get random crashes every few hours of operation; but below that it will crash immediately
2019-09-09T11:38:18 < jpa-> it's very fun to debug
2019-09-09T11:41:07 < Steffanx> I'd go lpc and use xp libs. Gives you more fun to debug
2019-09-09T11:42:31 < Steffanx> Like delays after enabling a clock. Busy wait loops with a simple counter to delay 250us, but those delays aren't 250us. And randomly your sysclock freq isnt what you expect it is
2019-09-09T11:43:23 < Steffanx> 9 out of 10 boards worked fine.

2019-09-09T13:59:20 < nuxil> i joined this channel when i started messing around with my nucleo.
2019-09-09T13:59:35 < nuxil> only been doing avr's before.
2019-09-09T14:00:10 < zyp> didn't we all do avrs before stm32?
2019-09-09T14:00:29 < nuxil> heh. i suppose
2019-09-09T14:01:38 < zyp> nuxil, may I ask where in norway you are located?
2019-09-09T14:02:02 < nuxil> a bit north of tromsø
2019-09-09T14:02:15 < nuxil> how about you?
2019-09-09T14:02:17 < zyp> ah, nice
2019-09-09T14:02:34 < zyp> I'm from the north myself, but I've lived on the south coast for the past 11 years or so
2019-09-09T14:04:00 < zyp> heh
2019-09-09T14:04:00 < nuxil> ?
2019-09-09T14:06:24 < nuxil> so. do you have any project youre working on?
2019-09-09T14:06:32 < nuxil> *stm32 projects
2019-09-09T14:06:43 < zyp> you being who?
2019-09-09T14:06:47 < nuxil> you
2019-09-09T14:07:45 < nuxil> you zyp.
2019-09-09T14:07:49 < zyp> I've got some finished projects and some unfinished projects, but I can't say I've been working much on either lately
2019-09-09T14:09:26 < zyp> and for the most recent project, I'll probably be going for nrf52 instead
2019-09-09T14:10:28 < Laurenceb_> >not using raspberry pi
2019-09-09T14:10:30 < zyp> I need to do some wireless stuff and I were playing around with stm32wb for the purpose a few months ago, but nrf52 seems easier to work with
2019-09-09T14:11:00 < zyp> Laurenceb_, way too big
2019-09-09T14:11:18 < Laurenceb_> that was a joke
2019-09-09T14:11:26 < Laurenceb_> rpi is a disaster zone
2019-09-09T14:11:31 < Laurenceb_> also >embedded lunix
2019-09-09T14:11:45 < nuxil> ah this nRF its a cortex M4 
2019-09-09T14:13:17 < zyp> yeah, so is stm32wb
2019-09-09T14:14:12 < zyp> to be fair, when I were playing around with stm32wb, it was super fresh and not all the documentation was available yet
2019-09-09T14:14:46 < nuxil> i have 2xPi's, they are mostly useless. but i do use one as a programmer for bare avr chips. the other i got retropi install on with 1400 nes and snes games :p
2019-09-09T14:15:00 < zyp> it should be easier to work with once it's actually documented and I don't just have a pile of example code to work with
2019-09-09T14:15:53 < nuxil> good docs is a must.
2019-09-09T14:16:10 < Laurenceb_> nuxil: rpi with decent PMIC, RTC, and wakeup/sleep might be useful
2019-09-09T14:16:27 < Laurenceb_> in theory BBB was that, in practice it was somehow even worse
2019-09-09T14:17:40 < zyp> the advantage of rpi is that it's so ubiquitous that it has decent software support
2019-09-09T14:17:49 < zyp> but yeah, the hardware is not all that impressive
2019-09-09T14:17:56 < zyp> although the rpi4 seems a decent improvement

2019-09-09T14:52:56 < day> nuxil: nah. i just checked it on google, and accidentally landed in this neighborhood
2019-09-09T14:53:13 < day> the super tiny streets with trees right next to them looks cute
2019-09-09T14:53:24 < Steffanx> Day must be german
2019-09-09T14:53:56 < day> here the streets are twice as wide, then a pedestrian path on either side and then rectangular properties with houses on them :P

2019-09-09T19:32:27 < catphish> if i have DMA copying timer values into a ring buffer, what it the correct way to determine the current pointer in that ring buffer? will "DMA channel x memory address register (DMA_CMARx)" be updated on every transfer? or do i need to calculate it from something else?

2019-09-09T19:37:08 < Thorn> FE1.1 is a nice IC part #
2019-09-09T19:37:29 < Thorn> >Low power consumption 115 mA 
2019-09-09T19:38:07 < catphish> got it - "The current transfer addresses (in the current internal peripheral/memory address register) are not accessible by software."
2019-09-09T19:39:09 < Thorn> catphish: consider using a double buffer instead of a ring buffer. that's how I did it iirc.
2019-09-09T19:41:12 < catphish> what would a double buffer look like?
2019-09-09T19:41:19 < catphish> can't quite envisage how that works
2019-09-09T19:42:07 < catphish> my goal by the way is to stream data from TIM2->CCR3 to USB
2019-09-09T19:42:46 < catphish> my intention was to have a large buffer that gets filled by the timer, and emptied whenever the usb is able to transmit

2019-09-09T19:46:56 < catphish> the answer to my original question seems to be that i can use the DMA_CNDTRx register to determine the ring buffer location
2019-09-09T19:47:05 < Thorn> one buffer is filled, the other is drained. then the buffers switch roles
2019-09-09T19:49:13 < catphish> that makes sense, i think i'm more comfortable with the ring if i can make it work though
2019-09-09T19:51:20 < Thorn> if fits especially well here since you know your usb packet size
2019-09-09T19:52:27 < qyx> w5500 is 132mA at 3V3 low power
2019-09-09T19:52:35 < qyx> or what part it was exactly
2019-09-09T19:55:39 < catphish> Thorn: the downside is that there's no guarentee when usb is ready to send data
2019-09-09T19:56:03 < catphish> so i'm using quite a large buffer to account for usb's bursty nature

2019-09-09T22:32:56 < catphish> Cracki: what i was hoping to do is simply make a precise copy of a disk, but as far as i can tell, this is completely impossible, because of the variation in rotation speed
2019-09-09T22:33:29 < Cracki> ;)
2019-09-09T22:33:51 < Cracki> that's one of the copy protection "mechanisms" they used for floppies, and CDs and on
2019-09-09T22:33:58 < catphish> essentially the end will never perfectly line up with the beginning
2019-09-09T22:34:19 < Cracki> obviously, so the end has to have some buffer so it never touches the beginning
2019-09-09T22:34:50 < Cracki> what do the specs say?
2019-09-09T22:35:06 < catphish> i *assume* that's always the case, the problem is that there's no reliabe way to know where that buffer is
2019-09-09T22:35:16 < Cracki> do they say you have to be perfect, or do they recommend writing at slightly higher density so you never hit the end?
2019-09-09T22:35:30 < catphish> if you could find it, it would be dramatically easier
2019-09-09T22:35:38 < Cracki> "where"? I'm saying buffer in the physical/geometric sense
2019-09-09T22:36:13 < catphish> you're absolutely correct, disks are written slightly denser so that there's a gap between the end and the beginning
2019-09-09T22:36:21 < catphish> the problem is that there's no way to know where that gap is :(
2019-09-09T22:36:25 < Cracki> yes, gap is what I had in mind
2019-09-09T22:36:28 < Cracki> uh
2019-09-09T22:36:39 < Cracki> don't you have a pulse per rotation?
2019-09-09T22:36:45 < Cracki> isn't that used for indexing?
2019-09-09T22:36:53 < Cracki> or do they use a sync pattern?
2019-09-09T22:37:02 < catphish> drives do generate a pulse per rotation, not all disk formats align with it
2019-09-09T22:37:12 < catphish> some use a sync pattern
2019-09-09T22:37:15 < Cracki> so it's a sync pattern that signals the beginning of the track?
2019-09-09T22:37:24 < catphish> sometimes yes
2019-09-09T22:37:29 < Cracki> you had some articles on this, yes?
2019-09-09T22:37:38 < Cracki> do any of them say what to rely on?
2019-09-09T22:37:49 < catphish> so you have to know whether 1) if the disk uses the sync pulse and if not, what the sync pattern is
2019-09-09T22:38:15 < Cracki> is that perhaps fixed for particular sizes, 3.5", 5.25", ...?
2019-09-09T22:38:16 < catphish> without that knowledge, there's no way to make a copy :(
2019-09-09T22:38:23 < catphish> no
2019-09-09T22:38:29 < Cracki> I don't believe you
2019-09-09T22:38:31 < Cracki> find a spec
2019-09-09T22:38:37 < catphish> it's totally up to the software reading the disk
2019-09-09T22:39:59 < Cracki> wikipedia sez >Each sector of data has a header that identifies the sector location on the disk
2019-09-09T22:40:17 < catphish> PCs always use the sync pulse, but other systems can use totally custom formats
2019-09-09T22:40:33 < Cracki> assuming multiple sectors per track, still you can either rewrite the whole track, or attempt to hit that sector
2019-09-09T22:40:47 < Cracki> perhaps that's why floppies get formatted
2019-09-09T22:40:57 < Cracki> so every sector gets a header
2019-09-09T22:41:04 < Cracki> just speculating, cba to read all this
2019-09-09T22:41:15 < Cracki> find the spec. that's the goal.
2019-09-09T22:41:24 < catphish> Cracki: most sane formats have addressed sectors, you're right
2019-09-09T22:41:30 < catphish> but not all floppies use such sane formats
2019-09-09T22:41:37 < Cracki> During formatting, the magnetizations of the particles are aligned forming tracks, each broken up into sectors, enabling the controller to properly read and write data.
2019-09-09T22:41:39 < Cracki> >>>
2019-09-09T22:41:42 < catphish> and some platforms have different formats for different software
2019-09-09T22:42:03 < Cracki> so you have to know the format, or guess it
2019-09-09T22:42:15 < Cracki> and given a format, read the disk
2019-09-09T22:42:16 < catphish> and that's the problem
2019-09-09T22:42:27 < catphish> if you know the format, you're good
2019-09-09T22:42:36 < catphish> but if you don't, you can't just make a 1:1 copy
2019-09-09T22:43:03 < catphish> (like you could with a continuous tape)
2019-09-09T22:43:13 < Cracki> and angular velocity variations prevent you from doing a physical copy?
2019-09-09T22:43:23 < Cracki> do you have statistics on how much that varies
2019-09-09T22:43:40 < catphish> right, because you'd end up misaligning at the end/start of wherever you started copying
2019-09-09T22:44:13 < Cracki> either give your drive an encoder to its spindle or build your own drive that does some absolute position scanning :P
2019-09-09T22:44:29 < catphish> it really depends on the platform, on PC all disks have to use the same format (it's hardwired into the controller)
2019-09-09T22:44:30 < Cracki> misalign by how much, that's the q
2019-09-09T22:44:53 < Cracki> dude, *within* the constraints of the given hardware, you HAVE to make assumptions
2019-09-09T22:45:04 < Cracki> without assumptions you have to have more capable hardware
2019-09-09T22:45:09 < catphish> the platform i'm interested in (Amiga) it's very common for disks to have obscure formats (either for copy protection, or to make maximum use of the space on the disk)
2019-09-09T22:45:22 < Cracki> still you have the assumption of "amiga"
2019-09-09T22:45:28 < Cracki> and *something* reads those disks
2019-09-09T22:45:49 < Cracki> so you specialcase for every "something" there was, is, or coulr be
2019-09-09T22:46:03 < qyx> maybe amiga software
2019-09-09T22:46:17 < catphish> the problem is that a disk could have a totally random sync sequence
2019-09-09T22:46:25 < catphish> only the software on that disk needs to know what it is :(
2019-09-09T22:46:45 < Cracki> either work from a spec or from a stack of actual real existing disks. don't worry about "what if"
2019-09-09T22:47:05 < catphish> well, i'm hoping *most* disks use the same sync sequence
2019-09-09T22:47:08 < Cracki> the software on that disk has to be read first, before it can actually read its own disk
2019-09-09T22:47:21 < catphish> and another big batch use the index pulse
2019-09-09T22:47:43 < Cracki> isn't that a catch 22?
2019-09-09T22:47:54 < catphish> Cracki: right, so track 1 will be in the "standard" format, and that will know how to load the rest of the disk, it's mad, but that's how they rolled in the 90s
2019-09-09T22:48:12 < Cracki> the OS has to be able to read _some_ part of the floppy before it can let the software _on_ the floppy read anything else on itself
2019-09-09T22:48:19 < Cracki> so _some_ part has to be standard
2019-09-09T22:48:28 < catphish> yep, so track 1 will always be in "amiga dos" format
2019-09-09T22:48:32 < Cracki> so you'll have to emulate amiga
2019-09-09T22:48:34 < catphish> after that, anything goes
2019-09-09T22:48:36 < Cracki> execute the disk
2019-09-09T22:49:05 < Cracki> sounds fair?
2019-09-09T22:49:20 < Cracki> just run it, observe behavior, record what it cares about
2019-09-09T22:49:20 < catphish> fair but not practical :)
2019-09-09T22:49:23 < Cracki> lol
2019-09-09T22:49:42 < Cracki> either you record exactly the info that disk cares about, or you record A LOT more info
2019-09-09T22:49:53 < Cracki> but A LOT more isn't feasible with standard drives
2019-09-09T22:50:10 < Cracki> so you better pimp your drive with some encoder
2019-09-09T22:50:32 < catphish> that could work, would have to be an insanely accurate encoder though
2019-09-09T22:50:40 < Cracki> 14 bit good enough?
2019-09-09T22:50:45 < Cracki> that's the magnetic thingy

2019-09-09T22:51:18 < Cracki> plop a radially polarized magnet on the shaft, magnetic encoder perpendicular to shaft, encoder senses direction of field, gives you angle
2019-09-09T22:51:24 < Cracki> some servos do that
2019-09-09T22:51:43 < Cracki> there are two common chips for this, both do 12-14 bits
2019-09-09T22:52:08 < catphish> 14 bits would just about be enough
2019-09-09T22:52:10 < srk> AS5047
2019-09-09T22:52:13 < Cracki> ^
2019-09-09T22:52:16 < catphish> (i think)
2019-09-09T22:52:31 < Cracki> you can work with significantly less bits. you just need to "undistort"
2019-09-09T22:52:32 < catphish> the actual resolution i'm working at is much higher than that
2019-09-09T22:52:42 < Cracki> angular velocity jitter is probably quite coarse
2019-09-09T22:52:50 < catphish> the encoder would be used with a PID to keep things aligned over time
2019-09-09T22:52:55 < catphish> right
2019-09-09T22:53:10 < Cracki> so you have it spin, record signal plus angle, and remap that to linear in software
2019-09-09T22:53:19 < srk> or run PLL :)
2019-09-09T22:53:31 < catphish> PLL sounds good
2019-09-09T22:53:34 < Cracki> writing is a little more fucky
2019-09-09T22:53:49 < catphish> shame the drive itself only generates 1 PPR
2019-09-09T22:53:49 < Cracki> PLL? what do you wanna lock on to?
2019-09-09T22:54:02 < Cracki> the data written to disk might have jitter in it already
2019-09-09T22:54:08 < catphish> you'd lock your data clock to the encoder pulses
2019-09-09T22:54:10 < Cracki> if the drive that wrote it wasn't quite perfect
2019-09-09T22:54:33 < catphish> jitter doesn't really matter
2019-09-09T22:54:40 < catphish> what matters is that the total length is spot on
2019-09-09T22:54:46 < Cracki> drives already do PLL on the magnetically encoded data and that has to be within spec
2019-09-09T22:55:00 < Cracki> how much spot on
2019-09-09T22:55:16 < Cracki> less than a fifth of a symbol per track?
2019-09-09T22:55:34 < catphish> pretty much exactly that, yes
2019-09-09T22:55:38 < Cracki> oh boy
2019-09-09T22:56:09 < catphish> because you need the symbol that lies on the boundary to be the right length
2019-09-09T22:56:12 < Cracki> your pimped drive will be the only one on the planet that can reproduce those disks
2019-09-09T22:56:16 < catphish> or close enough not to upset the reader
2019-09-09T22:56:23 < catphish> lol
2019-09-09T22:56:36 < Cracki> I think it's less work to just run the code on the disk and watch what it does
2019-09-09T22:56:54 < Cracki> not analyze it, just record its i/o
2019-09-09T22:57:04 < catphish> recording its IO is meaningless
2019-09-09T22:57:09 < catphish> it'll just read the magnetic data
2019-09-09T22:57:19 < Cracki> so?
2019-09-09T22:57:26 < catphish> well i already have that
2019-09-09T22:57:46 < catphish> would need to know how it extracts data from that
2019-09-09T22:57:54 < Cracki> hm yes, reproducing that onto another disk would involve knowing exactly what the code cares about
2019-09-09T22:58:09 < catphish> i do think the idea of a high resolution encoder doing PLL would work
2019-09-09T22:58:11 < Cracki> so at least looking at any timing it does
2019-09-09T22:58:32 < Cracki> there is no pll involved if you have an angular encoder
2019-09-09T22:58:42 < Cracki> pll is already involved in tracking the MFM signal
2019-09-09T22:58:49 < catphish> well, you need some kind of PID
2019-09-09T22:59:13 < Cracki> to upsample the angle?
2019-09-09T22:59:22 < Cracki> I see that, yes
2019-09-09T22:59:44 < catphish> basically you need to sync your writing bitstream to the rotational velocity
2019-09-09T22:59:55 < Cracki> rotational position/angle
2019-09-09T23:00:00 < catphish> actually yes
2019-09-09T23:00:06 < Cracki> anyway, yes
2019-09-09T23:00:06 < catphish> the angle is the important part
2019-09-09T23:00:18 < Cracki> and 14 bits is marginal, you say?
2019-09-09T23:00:24 < catphish> but the resolution of the data is much higher than the resolution of the encoder
2019-09-09T23:00:24 -!- jly [uid355225@gateway/web/irccloud.com/x-kmevvgyoqdeeuruq] has joined ##stm32
2019-09-09T23:00:29 < Cracki> I see why you'd want to use a pll to upscale that value artificially
2019-09-09T23:00:50 < catphish> i'm working at 80MHz resolution
2019-09-09T23:01:00 < catphish> rotation is 5Hz
2019-09-09T23:01:06 < Cracki> how many symbols per track?
2019-09-09T23:01:18 < Cracki> how is that measured, symbols per inch? symbols per turn?
2019-09-09T23:01:27 < catphish> so that's 16M (24 bits) of resolution per track
2019-09-09T23:01:37 < Cracki> is it, to use cd recording terms, constant angular velocity, or constant linear velocity?
2019-09-09T23:01:52 < catphish> constant angular
2019-09-09T23:01:56 < catphish> always 5Hz
2019-09-09T23:02:03 < Cracki> so data is more dense on inner tracks?
2019-09-09T23:02:06 < catphish> yes
2019-09-09T23:02:14 < Cracki> I'm talking about the disk, not how you sample it
2019-09-09T23:02:58 < Cracki> ah, it is indeed cosntant angular
2019-09-09T23:03:04 < catphish> i know :)
2019-09-09T23:03:13 < Cracki> I see upto 1 Mbit/s encoded in the MFM article
2019-09-09T23:03:44 < Cracki> so with a little oversampling, say 4-8 MHz, that's done?
2019-09-09T23:03:50 < catphish> the frequency of the actual pulses is 2MHz
2019-09-09T23:04:12 < catphish> no, less than that, 500KHz or 1MHz
2019-09-09T23:05:14 < Cracki> so at that data rate and 5 revolutions a second, a track might have 50k-200k bits
2019-09-09T23:05:36 < Cracki> so yes, 14 bits of angular resolution is a little low, I see why you need a PLL on that
2019-09-09T23:07:04 < Cracki> I find numbers of 300-600 rpm, that's 5-10 rps
2019-09-09T23:07:19 < catphish> that's true, it varies
2019-09-09T23:07:25 < catphish> all the systems i looked at use 5rps
2019-09-09T23:08:45 < catphish> i'm getting confused about these numbers now
2019-09-09T23:09:01 < Cracki> paper, sketch, notes :P
2019-09-09T23:10:12 < catphish> DD disk has 1MB per disk, that's 6250 bytes per track, 50,000 bits per track, which is 100,000 symbols of MFM
2019-09-09T23:10:35 < Cracki> 50kbit/track, that's the number you need
2019-09-09T23:10:40 < Cracki> or 100k symbols
2019-09-09T23:10:41 < catphish> at 5rps that's 500kHz, i was right

2019-09-09T23:11:14 < catphish> or double that (1MHz) for a 2MB HD disk, but i don't have an of those
2019-09-09T23:11:41 < Cracki> so you'd want 4-6 bits of multiplication on top of that 14 bit sensed angle
2019-09-09T23:12:14 < Cracki> 20 bits are ~1 million samples per track
2019-09-09T23:13:39 < Cracki> real world can fuck it up. I wouldn't rely on full 14 bits of precision, or on the PLL multiplication giving you the accuracy to hit it all perfectly
2019-09-09T23:13:42 < catphish> on a related note, i measured a jitter of 50uS per rotation
2019-09-09T23:13:58 < Cracki> you'd be served well by analyzing the track, looking for a quiet piece, and putting your start/end there
2019-09-09T23:14:05 < catphish> which is 25 symbols
2019-09-09T23:15:10 < catphish> that's a good point, if i found a long enough string of no transitions, i'd be absolutely fine
2019-09-09T23:15:25 < Cracki> do you have any disk where tracks have no "quiet section" of at least a handful of symbols?
2019-09-09T23:15:55 < Cracki> I can imagine copy protections that don't leave quiet sections
2019-09-09T23:16:15 < catphish> frankly, i don't have many disks at all right now, i'm just working on the theory, most of the disks i have are illegal copies that use standard formatting and have been overwritten many many times
2019-09-09T23:16:39 < Cracki> lol
2019-09-09T23:16:43 < catphish> i have a few originals, haven't inspected their streams yet
2019-09-09T23:16:57 < catphish> once i have the the theory down, i'll try to copy them
2019-09-09T23:21:11 < nuxil> What would be the best|reccomended way to change the frequency when using the dac as a signal generator? im using the dac with dma triggered by timer6.  should i recalulate and set new value for TIM6->ARR the the wanted frequency i want. or should i recalulate the amount of samples needed with a fixed trigger freq or are there other ways this is done ?
2019-09-09T23:21:51 < Cracki> what accuracy do you need?
2019-09-09T23:22:07 < nuxil> asking me ?
2019-09-09T23:22:08 < Cracki> you might have to do both
2019-09-09T23:22:09 < Cracki> yes
2019-09-09T23:22:41 < Cracki> timer period has granularity, recalculating the sample table (also length) has limits too
2019-09-09T23:22:42 < nuxil> well. accurcy at 1hz as long as its possible. 
2019-09-09T23:23:07 < Cracki> continuously changing, or changing at discrete instants?
2019-09-09T23:23:34 < nuxil> well i want some sweep functionality too at some point.,
2019-09-09T23:23:49 < Cracki> how well do you need it
2019-09-09T23:23:53 < catphish> Cracki: this is the stream from my test disk by the way :) https://nutty.tk/floppydata.80mhz.txt it's not terribly exciting in this form, just a list of MFM timings, this would be enough to emulate the disk, but not enough to write it back to a physical disk without some fancy encoder use
2019-09-09T23:24:08 < Cracki> the basic idea of sweeps is used for generating stepper motor ramps too
2019-09-09T23:24:21 < Cracki> and there people have different approaches as well
2019-09-09T23:24:24 < catphish> to emulate it, you could just play back the timings in a loop
2019-09-09T23:25:59 < Cracki> I don't see any four digit numbers so "quiet zone" might not be that easy
2019-09-09T23:26:28 < Cracki> I'm aware that it gives you a pulse for a magnetic transition, and if there aren't any, the amplifier will see transitions in noise
2019-09-09T23:27:02 < Cracki> what this needs is a histogram
2019-09-09T23:29:30 < Cracki> hah I see three modes (~315, ~470, ~625), each being bimodal itself
2019-09-09T23:32:04 < catphish> so in theory, there should be values of 320, 480 and 640, representing 4us 6us and 8us, which in turn represent 01 001 and 0001
2019-09-09T23:32:59 < Cracki> within 5-10%
2019-09-09T23:33:29 < catphish> because... every 2us is one symbol so a period between rising edges of 4us is a zero followed by a one, and a period of 6 is 2 zeros followed by a one, etc
2019-09-09T23:34:03 < catphish> it's limited to a maximum of 8us between rising edges, so you can only have 3 zeros in a row
2019-09-09T23:36:22 < catphish> some copy protection mechanisms will put a 3us symbol in there just to mess with you, and expect it to read back inconsistently, this is why i must oversample to reproduce it exactly
2019-09-09T23:38:16 < catphish> like this: https://i.imgur.com/YVOkIGX.jpg
2019-09-09T23:39:07 < nuxil> Cracki, how many samples for 1 presiod of a sinus wave would you call desent.. not too destorted. ? im currently using 128. 
2019-09-09T23:39:25 < Cracki> 2 at minimum :P
2019-09-09T23:39:29 < nuxil> lol
2019-09-09T23:39:31 < Cracki> 4-16 sounds usable
2019-09-09T23:39:51 < Cracki> look at how much oversampling stm32 (and avr) peripherals do on uart signals
2019-09-09T23:40:06 < Cracki> in the avr case it's 8-16x oversampling it wants
2019-09-09T23:40:21 < Cracki> and I think that's a solid number already
2019-09-09T23:42:41 < nuxil> i did a once a dds on a avr atmega324, it had 1hz precition upto 32k. then it was 2hz steps upto 65khz and so on :D 
2019-09-09T23:44:21 < Cracki> if you want a sine sweep, figure out the analytic (closed form) solution
2019-09-09T23:44:40 < Cracki> it's a sine of some square of time I think
2019-09-09T23:45:07 < Cracki> that's what you get to turn into ones and zeros. that's what I had to do for a stepper motor acceleration ramp anyway
2019-09-09T23:45:46 < Cracki> same thing I did you would probably have to do, except you keep running down a sine table ever faster
2019-09-09T23:46:11 < Cracki> it involves calculating the time until the next pulse (or sample)
2019-09-09T23:46:38 < Cracki> the time betwen samples/pulses is something like sqrt(t+1)-sqrt(t) times some factor
2019-09-09T23:46:39 <@englishman> Thorn: stt vs mtt iirc
2019-09-09T23:47:15 < Cracki> and *that* you can have the fpu do, or you use a table and some invariants for it
2019-09-09T23:47:45 < catphish> well i'm in 2 minds now about whether to 1) continue to work on this magnetic data streaming protocol 2) write a mass storage device for standard formats first
2019-09-09T23:47:46 < Cracki> and that interval between samples/pulses is what you put into the timer's period
2019-09-09T23:48:05 < nuxil> im already enabled my fpu to do the calcs for sin tables etc.  i checked the asm code and saw the fpu instructions :)
2019-09-09T23:48:15 < Cracki> do mass storage for standard formats. that'll probably give you success quicker
2019-09-09T23:48:56 < catphish> maybe i'll take a breather from the low level disk stuff, learn how to make a mass storage device, implement the standard format, and come back to the raw stuff later
2019-09-09T23:49:16 < Cracki> is there anything briefer than "experience of success" to name the experience of success that rewards you when you've done something?
2019-09-09T23:49:45 < catphish> it's often called "a win"
2019-09-09T23:50:01 < Cracki> when the floppy MSD works, is that a win?
2019-09-09T23:50:06 < catphish> yes
2019-09-09T23:50:11 < Cracki> who lost? :>
2019-09-09T23:51:08 < catphish> this will take a while, i have to learn MSD first :)
2019-09-09T23:51:22 < catphish> but that's ok, this was always one of the 2 goals for the project
2019-09-09T23:51:34 < Cracki> excellent
2019-09-09T23:51:59 < catphish> 1) mass storage device for amiga "ADF" format 2) custom program to read and write "raw" magnetic streams
2019-09-09T23:53:19 < catphish> i'm very happy the hardware works as it should anyway, and is able to correctly stream the 80MHz sampled magnetic data to the PC over USB
2019-09-09T23:53:32 < catphish> that's a lot of steps already
2019-09-09T23:53:41 < catphish> several wins :)

2019-09-10T02:20:11 < Cracki> "striving" also seems to be a good translation, apart from the obvious
2019-09-10T02:36:19 < catphish> i'm still in awe that nobody ever specified dumb standard usb protocols like "text pipe" and "block data store"

2019-09-10T03:07:29 < aandrew> I can't seem to get the cycle counter to do it's thing on F7
2019-09-10T03:07:46 < aandrew> CoreDebug->DEMCR |= CoreDebug_DEMCR_TRCENA_Msk;

2019-09-10T03:08:03 < aandrew> DWT->CTRL |= (1 << 0);
2019-09-10T03:08:07 < aandrew> that should do it
2019-09-10T03:08:13 < aandrew> but DWT->CYCCNT is always zero
2019-09-10T03:08:25 < aandrew> the LAR key is 0xc5acce55
2019-09-10T03:10:05 < dongs> larp key
2019-09-10T03:10:20 < dongs> Thorn: why would you expect them to
2019-09-10T03:10:24 < dongs> USB3 is compeltely different from 2
2019-09-10T03:10:38 < dongs> when you have a USB3 hub and plug in a bunch of USB2 devices, tehy all bunch up over 480mbit link
2019-09-10T03:10:43 < dongs> instead of even touching 10gbps usb3 link
2019-09-10T03:11:08 < Thorn> ok
2019-09-10T03:11:17 < dongs> there ARE chips that do 2.0 > 3.0 aggregation
2019-09-10T03:11:32 < dongs> but you aren't gonna see those in a shitty $10 chinahub
2019-09-10T03:12:14 < aandrew> yeah I occasionally look for those hubs without much luck
2019-09-10T03:12:21 < aandrew> MPP or some kind of acronym like that
2019-09-10T03:13:56 < catphish> Thorn: that's actually really annoying, means you can't put a bunch of high speed USB devices on a single USB 3 port :(
2019-09-10T03:14:05 < dongs> correct
2019-09-10T03:14:40 < rajkosto> i havent seen a single one that does
2019-09-10T03:14:51 < rajkosto> isnt the packet format different for 3.0 anyway
2019-09-10T03:14:58 < catphish> it would be useful to buy a "hub" that was actually a bunch of USB2 ports with usb3 backhaul
2019-09-10T03:15:10 < dongs> i saw some one-off commercial thing that did like 8 2.0 porst to 3.0 for use wiht printers and other shit
2019-09-10T03:15:17 < dongs> trying to find it again
2019-09-10T03:15:24 < dongs> there's an IC that did it by VLI or something as well
2019-09-10T03:15:35 < catphish> not sure if you could do this with usb3, but definitely can with lightning
2019-09-10T03:15:49 < catphish> i've never seen such a hub though
2019-09-10T03:16:08 < catphish> i don't really understand the relationship between lightning and usb
2019-09-10T03:16:16 < dongs> the fuck is lighting
2019-09-10T03:16:19 < dongs> are you an apple faggot
2019-09-10T03:16:30 < catphish> i mean thunderbolt :)
2019-09-10T03:16:45 < dongs> how does thinderbolt help anything
2019-09-10T03:17:02 < rajkosto> thunderbolt is more like pci-e 
2019-09-10T03:17:03 < Thorn> >TT Think Time
2019-09-10T03:17:03 < rajkosto> than usb3.0
2019-09-10T03:17:05 < Thorn> wtf
2019-09-10T03:17:21 < catphish> well, thunderbolt runs over usb-c, i probably mistakenly relate it with USB3
2019-09-10T03:17:31 < rajkosto> and since pci-e usb controllers exist, you can just stick one on there
2019-09-10T03:18:19 < catphish> you can definitely run pcie usb controllers on a lightning port, but i guess that doesn't address the queston of USB3
2019-09-10T03:18:25 < aandrew> catphish> it would be useful to buy a "hub" that was actually a bunch of USB2 ports with usb3 backhaul
2019-09-10T03:18:28 < aandrew> ^^ 
2019-09-10T03:18:30 < aandrew> that is exactly what I wanted it for
2019-09-10T03:18:41 < catphish> can one make a USB port that attaches by USB?
2019-09-10T03:19:03 < rajkosto> wait for dongs to dig up the specific VLI model number that does it
2019-09-10T03:19:24 < rajkosto> the cheap VLI hubs that are everywhere do usb2.0 and usb3.0 separately tho
2019-09-10T03:19:25 < dongs> aandrew: right, and  that existed a few yearsa back, i still cant find the link tho
2019-09-10T03:19:48 < catphish> would be cool to see what device can do it though, i was under the impression it was impossible with a hub, and you'd need to simulate new root ports somehow
2019-09-10T03:19:49 < Thorn> https://slideplayer.com/slide/4460567/
2019-09-10T03:19:55 < catphish> but i'd enjoy being wrong
2019-09-10T03:20:24 < rajkosto> Thorn, the Transaction translator was for converting USB Fullspeed to highspeed
2019-09-10T03:20:44 < rajkosto> since those run over the same wires
2019-09-10T03:20:46 <@englishman> usb2 to 10gige adapter
2019-09-10T03:20:52 < catphish> weird that they didn't bring that forward
2019-09-10T03:21:00 < catphish> (the standard translator)
2019-09-10T03:21:06 < rajkosto> initial usb2.0 hubs didnt have it so full speed devices shared their 12mbps
2019-09-10T03:21:12 < aandrew> dongs: yeah I knew the chip too, it's long gone rom my memory
2019-09-10T03:21:15 < rajkosto> catphish, well in usb3.0 its different wires for superspeed and highspeed
2019-09-10T03:21:27 < rajkosto> so the cheapest way is to do them completely separate
2019-09-10T03:21:39 < rajkosto> the packet format and signalling changed for SS vs HS too
2019-09-10T03:21:46 < rajkosto> as SS is now full-duplex as well
2019-09-10T03:21:50 < catphish> rajkosto: well sure, but that doesn't explain why you can't translate transactions from HS devices over the superspeed backhaul
2019-09-10T03:22:23 < catphish> i'm sure there's a good reason why you can't, or perhaps you can and devices just don't
2019-09-10T03:22:48 < aandrew> VL670?
2019-09-10T03:23:04 < rajkosto> well HS devices have to "upgrade" to superspeed at which point they switch which lines they use
2019-09-10T03:23:47 < dongs> aandrew: yes that
2019-09-10T03:23:57 < dongs> and put that behind a 4 port usb3 hub
2019-09-10T03:24:01 < dongs> or wahtever
2019-09-10T03:25:13 < catphish> anyone sell VL670 passthrough dongles?
2019-09-10T03:25:18 < Thorn> ok now how to signal CDP to the device
2019-09-10T03:25:20 < dongs> is VIA labs any relation to the fags who did retarded AMD motherboards?
2019-09-10T03:25:22 < catphish> that would be a really useful tool
2019-09-10T03:25:34 < rajkosto> FL6000 is a hub that does the translation
2019-09-10T03:25:36 < aandrew> https://web.archive.org/web/20120311221810/http://via-labs.com/en/resources/pressroom/2012/PR120104-usb2expressway.jsp
2019-09-10T03:25:37 < Thorn> I hole I'm not going to need some special hub for that
2019-09-10T03:25:40 < rajkosto> catphish, i can see them when i search for VL670
2019-09-10T03:26:17 < catphish> such chinese
2019-09-10T03:26:38 < rajkosto> https://www.via-labs.com/product_show.php?id=96 these
2019-09-10T03:27:02 < catphish> FL6000 looks like the thing :)
2019-09-10T03:27:42 < rajkosto> for the VL670 it seems you would need one per usb2.0 device
2019-09-10T03:27:52 < dongs> rajkosto: correct
2019-09-10T03:28:06 < dongs> so you put it behind some (VL's for example) USB3 hub chip
2019-09-10T03:28:15 < rajkosto> the fresco logic FL6000 page isnt loading for me
2019-09-10T03:28:21 < rajkosto> but their Q-One tech seems to do the same
2019-09-10T03:28:37 < dongs> ooh
2019-09-10T03:28:39 < dongs> chinkese 
2019-09-10T03:28:40 < dongs> nice
2019-09-10T03:28:43 < dongs> page loaded
2019-09-10T03:28:46 < rajkosto> while integrating it into the hub
2019-09-10T03:28:52 < rajkosto> so you only need one
2019-09-10T03:28:54 < catphish> page loads sometimes :)
2019-09-10T03:29:11 < catphish> this might be what i want, but it might not be, its just a photo https://www.via-labs.com/archive/images/product/VL671_03262.jpg
2019-09-10T03:29:26 < rajkosto> yes but need one per device
2019-09-10T03:29:32 < rajkosto> http://www.frescologic.com/zh/product/single/fl6000/ has it in the hub itself
2019-09-10T03:29:38 < catphish> yeah the hub looks nice
2019-09-10T03:30:12 < rajkosto> both have problems
2019-09-10T03:30:20 < rajkosto> the FL6000 seems to need a custom driver to run in Q-One mode
2019-09-10T03:30:28 < catphish> oh, someone linked that pcb i got the photo of, it it what i hoped
2019-09-10T03:30:29 < rajkosto> while the VL670 doesnt work with all devices you can hook it up to
2019-09-10T03:30:35 < dongs> 'custom driver'?
2019-09-10T03:30:36 < dongs> why would it need to
2019-09-10T03:30:55 < rajkosto> https://github.com/FrescoLogic/FL6000
2019-09-10T03:31:02 < catphish> also, i see VL671
2019-09-10T03:31:06 < catphish> is tha essentially the same?
2019-09-10T03:31:11 < rajkosto> VL671 is the eval board for the Vl670
2019-09-10T03:31:24 < catphish> oh ok
2019-09-10T03:31:29 < rajkosto> or not
2019-09-10T03:31:33 < rajkosto> i see VL671 on the chip itself
2019-09-10T03:31:40 < catphish> yeah thats what i thought
2019-09-10T03:31:57 < rajkosto> good luck finding datasheets/firmware for the VLI parts without being in their cabal
2019-09-10T03:32:02 < rajkosto> sometimes they leak
2019-09-10T03:32:03 < rajkosto> sometimes not
2019-09-10T03:32:53 < catphish> i suspect 671 is a replacment
2019-09-10T03:33:01 < catphish> they don't list 670 on their product page
2019-09-10T03:34:34 < rajkosto> ive used the cheap VLI usb3 hub with only leaked datasheet and firmware found on the net
2019-09-10T03:34:42 < rajkosto> would be nice to have their configurator for the firmware

2019-09-10T11:35:17 < carl0s-> Hi. I just picked up another Chinese dev-board/eval board (Wildfire stm32H750 480MHz thing with lots of 32-bit SDRAM for a framebuffer etc, and shed-loads of pins). Anyway this has come with a CMSIS-DAP debugger. My previous stuff uses an ST-Link v2 (probably a clone, but looks real, unlike the standard cheap clone), and I also have a Black Magic Probe. I'm just wondering, is there any benefit of one over the others? I'm
2019-09-10T11:35:18 < carl0s-> using STM32CubeIDE which is basically TrueStudio evolved as far as I can tell (Eclipse based), and the ST Link has always done what it's supposed to do. All these board seems to be based off a cheap STM32 MCU (205-rgbt6 in the CMSIS-DAP, F103 in the st link, and not quite sure on the BMP.. f103 again I think).
2019-09-10T11:35:19 < carl0s-> but I watched a video of Mike Electronics pulling apart a Microchip ICD v4 debugger, and that thing has all sorts in it.. external ram, flash, MCU, and a bloody great spartan FPGA.

2019-09-10T11:38:16 < PaulFertser> carl0s-: with cmsis-dap you count only on host software to know how to work with the chip. With BMP its firmware needs to know how to program its flash.
2019-09-10T11:41:40 < carl0s-> I see, thanks Paul. I suppose my other question is, what is the Microchip ICD doing with all that FPGA stuff? It must be doing something clever that these $10 STM32 debuggers can't do?
2019-09-10T11:42:09 < ThatDamnRanga> carl0s-, the Microchip ICD is an evolution of what was needed for the old-world MCUs like the PIC
2019-09-10T11:42:22 < ThatDamnRanga> there was no standardised debugging platform etc like with the ARMs
2019-09-10T11:42:53 < PaulFertser> carl0s-: probably autonomous flashing for mass production? Or capture of parallel trace? IDK really, you can check its features to see what it can.
2019-09-10T11:42:53 < carl0s-> Ah, right. So because they have no SWD type stuff, they need all that? It's not actually doing anything any smarter then? I'm not missing out on something that I should be looking for on the ST side ?
2019-09-10T11:43:04 < ThatDamnRanga> it's also set up to cope with many different architectures
2019-09-10T11:43:26 < ThatDamnRanga> some of which only expose traditional JTAG with its many IOs
2019-09-10T11:44:29 < ThatDamnRanga> in short, for your use case, it'll offer fuck all more than anything else :P
2019-09-10T11:44:51 < carl0s-> I see. Thanks very much! I opened up this new CMSIS-DAP thing this morning thinking.. oooh I wonder if it's packed full of fpga cleverness, and there was nothin' in it again, so I just wondered if there was some more advanced stuff I should find out about, but I guess not :-)
2019-09-10T11:44:59 < carl0s-> haha thanks @that

2019-09-10T11:45:54 < ThatDamnRanga> the Atmel/Microchip ATMEL-ICE is literally just a rebadged low pincount SAM chip (aka EDBG) and a bunch of level shifters
2019-09-10T11:47:16 < carl0s-> I'm sort of wondering why this board has come with a CMSIS-DAP (they advertised it as the 'high speed version' for a few dollars more than the other one) instead of an ST-Link v2. Any obvious reason there? The ST Link v2 has the same 20 pin header.
2019-09-10T11:47:45 < ThatDamnRanga> 20-pin?
2019-09-10T11:48:24 < ThatDamnRanga> most SWD headers are 2x5pin
2019-09-10T11:48:56 < carl0s-> yeah 20 pin. Same on my st-link v2. It has jtag and swd in the one I think, plus reset and power etc.
2019-09-10T11:49:57 < ThatDamnRanga> the 20-pin is 7 live pins, plus a whole lot of grounds
2019-09-10T11:50:02 < ThatDamnRanga> (and four NC pins)
2019-09-10T11:50:21 < carl0s-> Ah right.
2019-09-10T11:50:33 < ThatDamnRanga> the ARM 'standard' is 10 pins
2019-09-10T11:51:01 < ThatDamnRanga> has, as best I can see, all the same functionality in a lot less space
2019-09-10T11:52:07 < carl0s-> Both of these boards (my Alientek Stm32F767 one, which I use with St-Link V2 & 20 pin IDC ribbon, and this wildfire stm32h750), use the same connector between board & programmer. it's just that one programmer is an st link and the other is a cmsis-dap
2019-09-10T11:52:32 < ThatDamnRanga> In real world use, you'll likely find them interchangeable

2019-09-10T11:53:02 < PaulFertser> stlink can't do raw jtag, so you can't configure FPGA/CPLD with it, you can't debug RiscV and MIPS etc.
2019-09-10T11:53:42 < carl0s-> oh right.
2019-09-10T11:56:00 < carl0s-> I suppose given that I'm using STM32CubeIDE, (which I assume is just an evolved version of TrueStudio?) it'll be less hassle if I stick with the ST-Link V2. As long as the pin outs match, i.e. it doesn't damage this new board that came with the CMSIS-DAP.
2019-09-10T11:56:51 < ThatDamnRanga> Honestly don't think it'll make any difference one way or another
2019-09-10T11:57:01 < carl0s-> great, thanks.

2019-09-10T12:10:20 < PaulFertser> zoobab: :) then it's no longer an stlink
2019-09-10T12:11:18 < carl0s-> You can flash the ST Link v2 into a mini-JLink or something as well can't you? Or is that just the ones built-in to the Disco boards? I'm pretty sure my L4R9I-DISCo smartwatch style discovery board has an option to reflash the built-in st-link into a segger j-link. Again, not at all sure what benefits that might have to me.
2019-09-10T12:12:25 < zoobab> stm32 can be reflashed with JTAG as well
2019-09-10T12:13:03 < zoobab> I showed 2 bluepills: one as a JTAG adaptor, the other one as a target

2019-09-10T14:00:19 < cdnChrisDvo> hello all; anyone here have experience with the eeprom emulation examples ... I have it compiled up for my stm32f030f4px -- and while it throws no errors and appears to read / write, the read values are untouched from their initializer.  Examples use: uint16_t VirtAddVarTab[3] = {0x5555, 0x6666, 0x7777}; but I'm struggling to find out how these addresses are chosen, any advice ?
2019-09-10T14:01:09 < PaulFertser> cdnChrisDvo: hehe, the library is relatively sane, but the appnote (and this specific example from it) are just fucked-up.
2019-09-10T14:02:52 < cdnChrisDvo> @PaulFertser : agreed, it didn't take much massaging to get it compiled (I'm using HAL, but just imported the non-HAL calls into eeprom.c and a few missing defs ... now just need a little bit more knowledge ...
2019-09-10T14:03:14 < PaulFertser> cdnChrisDvo: I can send you my "fork" of the library (I was using it on F1) with appropriate comments via email if you want it.
2019-09-10T14:04:02 < Cracki> how "virtual" addresses are chosen? they aren't, they are whatever key you want them to be.
2019-09-10T14:04:03 < cdnChrisDvo> @PaulFertser : appreciate that, a link will do :)
2019-09-10T14:04:10 < Cracki> it's a key-value store, kinda
2019-09-10T14:04:17 < PaulFertser> cdnChrisDvo: I got no link, I can just send it to you via email right now :)
2019-09-10T14:04:21 < Cracki> except keys are 16 bit numbers
2019-09-10T14:04:46 < PaulFertser> Cracki: yep, agreed, and that's really weird and not handy. I use appropriate enums for the virtual addresses.
2019-09-10T14:04:53 < Cracki> you get the "journal" character of the construction, yes?
2019-09-10T14:05:12 < Cracki> sure you can choose values that make sense to you
2019-09-10T14:05:18 < Cracki> but you don't have to
2019-09-10T14:05:50 < Cracki> mostly asking him since he showed up here and you have a solution you understand already :P
2019-09-10T14:06:00 < cdnChrisDvo> @Cracki : aah, ok that makes much more sense ... 
2019-09-10T14:06:01 < PaulFertser> The problem is that you need to have everything in sync, you need to not forget to add them all to that VirtAddVarTab.
2019-09-10T14:06:09 < Cracki> uh
2019-09-10T14:06:20 < Cracki> that eeprom emulation doesn't care what values you have
2019-09-10T14:06:31 < cdnChrisDvo> @Cracki : okay, so what is this "journal" character you speak of ?
2019-09-10T14:06:37 < Cracki> you just need to ask for the same "addresses" to get the same values back
2019-09-10T14:06:46 < PaulFertser> It kinda does, it scans the page for all the "possible" keys iirc.
2019-09-10T14:06:56 < PaulFertser> When moving data to another page.
2019-09-10T14:07:14 < Cracki> the "journal" merely means that it appends data in most cases, which saves erase cycles.
2019-09-10T14:07:48 < Cracki> like foo=10, NO foo=20, WAIT foo=7, ...
2019-09-10T14:08:03 < Cracki> and when you ask foo? it tells you the most recent value
2019-09-10T14:08:21 < Cracki> and when a page is full, it takes all the most recent values and writes them to the other flash page
2019-09-10T14:08:48 < Cracki> it doesn't scan for all possible keys
2019-09-10T14:08:51 < PaulFertser> I think they added VirtAddVarTab array specifically for the code that scans for most recent values.
2019-09-10T14:08:54 < Cracki> it scans the entries, keeps track of those
2019-09-10T14:09:20 < PaulFertser> Ok, I might have forgotten the details by now. Or we're talking about slightly different versions of the library.
2019-09-10T14:09:20 < Cracki> hm well yes it has to test all possible keys... unless it can be a little smarter about that
2019-09-10T14:09:28 < Cracki> it's too early for me to think that deeply
2019-09-10T14:09:41 < Cracki> I had some appnote from st in front of me some months ago
2019-09-10T14:10:08 < Cracki> it's entirely possible to scan entries, and invalidate (all-0) an entry once it's processed
2019-09-10T14:10:21 < Cracki> or keep a bitmap of entries, equivalently, so you know when you're done
2019-09-10T14:10:50 < cdnChrisDvo> ok, understood.
2019-09-10T14:11:07 < Cracki> basically, you can store stuff :P
2019-09-10T14:11:30 < PaulFertser> I just made it to look at vaddr = 0 till EEPROM_VAR_CNT which comes last in the enum.
2019-09-10T14:11:34 < Cracki> but you have to use the procedures, no straight pointer/reference access
2019-09-10T14:11:53 < cdnChrisDvo> tracing through I see the call to EE_Format is failing
2019-09-10T14:11:55 < Cracki> it's certainly possible that their reference code is dumb
2019-09-10T14:12:13 < cdnChrisDvo> invalid page I believe 
2019-09-10T14:12:35 < cdnChrisDvo> How does it determine where (physically) to write values into the flash ?
2019-09-10T14:12:48 < PaulFertser> cdnChrisDvo: just use my code ;)
2019-09-10T14:13:24 < Cracki> the ref impl gets assigned at least two pages it can manage.
2019-09-10T14:13:41 < PaulFertser> I add a suitable entry to ld script.
2019-09-10T14:13:53 < Cracki> *that* is important
2019-09-10T14:14:16 < cdnChrisDvo> indeed that seems like the important bits... I've not modified at all my ld script.

2019-09-10T14:42:14 < PaulFertser> cdnChrisDvo: full linker script: http://paste.debian.net/1099841/ but I guess you're just not telling the linker to use the file you modified.

2019-09-10T14:59:49 < Steffanx> But but that isnt the question.  I know the alternatives. I want to know if the license allows me to ignore those alternatives
2019-09-10T15:00:10 < Steffanx> Whether it's a good idea is irrelevant :P

2019-09-10T18:37:00 < grummund> this is the guide i'm following but it stops short of actually flashing from within eclipse

2019-09-10T18:56:52 < Thorn> $8-9k
2019-09-10T18:57:11 < Thorn> right in the comfortable range for dongs
2019-09-10T18:57:40 < grummund> PaulFertser: you can flash the target from within eclipse?  and did you install anything else other than GNU MCU Eclipse itself?
2019-09-10T18:58:11 < PaulFertser> grummund: not only flash, debug. I basically followed his guide to install everything including OpenOCD.
2019-09-10T18:59:30 < grummund> so i guess you manually defined the external tool configuration within eclpse

2019-09-11T02:47:30 < ThatDamnRanga> it was a 'nice to have'
2019-09-11T02:47:44 < ThatDamnRanga> doing all the config via CAN makes more sense in the scope of the project anyway
2019-09-11T02:47:52 < ThatDamnRanga> just more effort on the PC side

2019-09-11T02:49:41 < roomba> 'slim' as a dating profile description = under 300lbs
2019-09-11T02:50:40 < ThatDamnRanga> nah, just where it would mean 'skinny' elsewhere it's closer to the usual 'cuddly'

2019-09-11T05:01:10 < englishman> doesnt look like it has any chips inside. just some dumb pullup resistors, per usbc spec
2019-09-11T05:01:15 < englishman> its usb2 as well so doesnt need a chip
2019-09-11T05:01:53 < englishman> maybe download and read the FREE usb-c spec

2019-09-11T06:47:10 < mawk> you can signal tasks ThatDamnRanga 
2019-09-11T06:47:13 < learningc> stm32
2019-09-11T06:47:17 < mawk> I know stm8 but not stm3
2019-09-11T06:47:18 < mawk> ah
2019-09-11T06:47:21 < mawk> ##stm32 obviously
2019-09-11T06:47:32 < mawk> myself I just read HAL code and reference manuals learningc 
2019-09-11T06:47:35 < mawk> and it goes fine
2019-09-11T06:49:48 < ThatDamnRanga> hmm... Looks like I'm going about this the wrong way
2019-09-11T06:50:34 < ThatDamnRanga> I /need/ the be able to do things in a vaguely multithreaded manner anyway. Can't exactly have the UI stop normal operation. And doing that with ISRs alone risks things clobbering each other
2019-09-11T06:51:37 < learningc> mawk, which reference manual exactly?
2019-09-11T06:52:17 < ThatDamnRanga> the reference manual for the chip of your choice
2019-09-11T06:52:59 < mawk> just wake up tasks from your ISRs ThatDamnRanga 
2019-09-11T06:53:28 < ThatDamnRanga> yeah, that might be a go... it's a rather large change from the singlethreaded way of thinking
2019-09-11T07:06:08 < learningc> I heard the HAL is bloated. Should I bother using it?
2019-09-11T07:06:39 < mawk> at least read it
2019-09-11T07:06:47 < mawk> when you don't get something
2019-09-11T07:06:56 < mawk> bloated is a point of view, use it if you wish
2019-09-11T07:07:13 < rajkosto> hal man bad use cmsis and stdperiph instead
2019-09-11T07:07:51 < mawk> lol
2019-09-11T07:08:02 < mawk> isn't stdperiph the old thing
2019-09-11T07:08:13 < rajkosto> its just functions that write to registers
2019-09-11T07:08:16 < rajkosto> no attempted "abstraction"
2019-09-11T07:08:30 < rajkosto> their parameters are well documented
2019-09-11T07:10:42 < ThatDamnRanga> I believe stdperiph is abandoned/deprecated now
2019-09-11T07:12:57 < rajkosto> its what comes with cmsis for the chips
2019-09-11T07:13:19 < learningc> So what should I use instaed of sdtpheriph?
2019-09-11T07:14:00 < mawk> try HAL for a couple days to learn the interfaces
2019-09-11T07:14:05 < mawk> or use libopencm3 for instance
2019-09-11T07:14:31 < ThatDamnRanga> You've got a number of options. The heavy and 'chip independent' mbed. The HAL which is a bit better. Or drop down a little further to CMSIS if you want something 'abstracted' but not very vendor specific. 
2019-09-11T07:14:49 < ThatDamnRanga> Or you could go all the way down and pretend you're playing on an AVR or PIC and register bash.
2019-09-11T07:15:18 < rajkosto> or use stdperiph which is just functions that register bash for ya
2019-09-11T07:18:13 < learningc> CMSIS is a library?
2019-09-11T07:18:41 < rajkosto> CMSIS are "packs" of c/h files that get copied into your project by your ide for hardware support
2019-09-11T07:18:41 < ThatDamnRanga> CMSIS is a 'standard' (ish) framework that forms part of the ARM standards
2019-09-11T07:19:09 < ThatDamnRanga> basically with the idea that core 'stuff' is really chip-independent... doesn't quite work like that in practice but eh
2019-09-11T07:19:33 < learningc> With CMSIS, I can use it for any stm32 devices?
2019-09-11T07:20:07 < ThatDamnRanga> any ARM devices
2019-09-11T07:20:47 < ThatDamnRanga> Honestly if this is all a bit deep right now, and you'd rather an 'arduino style' approach, check out mbed... and just disable the RTOS
2019-09-11T07:21:07 < rajkosto> whatever you do dont check out stm32duino
2019-09-11T07:21:38 < ThatDamnRanga> lol... An attempt was made, not a very good one, but one was made
2019-09-11T07:21:53 < mawk> CMSIS isn't like the other ones learningc 
2019-09-11T07:21:56 < mawk> it's just the registers and everything
2019-09-11T07:24:42 < learningc> well, I like to play at the register level
2019-09-11T07:24:51 < mawk> just CMSIS then
2019-09-11T07:25:02 < mawk> but LL (HAL's cousin) is fine for that too
2019-09-11T07:25:09 < mawk> it's like an inch above register level
2019-09-11T07:25:19 < mawk> helper functions to set individual parts of a register without the nasty bitshifting
2019-09-11T07:25:34 < learningc> Or can I just access with my own pointers to the register's address?
2019-09-11T07:25:44 < mawk> that's what you'd do with CMSIS
2019-09-11T07:25:54 < mawk> don't inflict that to yourself with magic numbers and everything
2019-09-11T07:25:56 < rajkosto> mawk, isnt that just this https://github.com/nematix/stm32f10x-stdperiph-lib/blob/master/Libraries/STM32F10x_StdPeriph_Driver/src/stm32f10x_i2c.c
2019-09-11T07:26:22 < mawk> that looks like HAL rajkosto 
2019-09-11T07:26:25 < mawk> LL is lower level
2019-09-11T07:26:27 < rajkosto> its stdperiph
2019-09-11T07:26:29 < mawk> yes
2019-09-11T07:26:32 < dongs> LL is disgusting
2019-09-11T07:26:35 < dongs> all the ugliness of HAL
2019-09-11T07:26:38 < mawk> lol
2019-09-11T07:26:39 < learningc> I also want to do some usb communication stuffs
2019-09-11T07:26:39 < dongs> but even less features
2019-09-11T07:26:48 < dongs> and LOL_EVERYTHING_IN_CAPS

2019-09-11T07:26:57 < rajkosto> mawk, i foudn it at a good abstraction level especially if you let the compiler optimize/inline those funcs
2019-09-11T07:26:59 < mawk> you want easy USB but you want register level access
2019-09-11T07:27:17 < mawk> I see rajkosto 
2019-09-11T07:27:47 < ThatDamnRanga> learningc, are you still 'learning c' or is the nick legacy?
2019-09-11T07:27:58 < rajkosto> they convert to a few register writes since all the #defines in stdperiph that you pass into the functions are already setup to match the bits that go into the registers
2019-09-11T07:28:27 < learningc> ThatDamnRanga, It's legacy right now. 
2019-09-11T07:28:53 < learningc> But in C you always have a bit to learn every year
2019-09-11T07:29:03 < ThatDamnRanga> I won't argue with that
2019-09-11T07:30:25 < learningc> Many are also suggesting moving to rust. Is it worth it?
2019-09-11T07:30:56 < learningc> let rust = c;

2019-09-11T08:00:17 < Thorn> learningc: I've always wondered how many of those who tell everyone to use rust are actual electronics designers. (my guess is about 0%)
2019-09-11T08:05:38 < learningc> Thorn, electronics designer at what level? chip design level or pcb design level?
2019-09-11T08:06:08 < Thorn> pcb/system/firmware of course
2019-09-11T08:07:17 < learningc> that's a norm these days

2019-09-11T08:20:07 < ThatDamnRanga> I've defined a function, it takes two arguments

2019-09-11T08:38:08 < qyx> except they may be written wrong
2019-09-11T08:38:29 < qyx> you didn't even paste the code, which should be the first thing

2019-09-11T13:59:15 < jadew> well, they do have a lot of that
2019-09-11T14:00:44 < Cracki> they have a lot of women's cocks too?
2019-09-11T14:00:53 < Cracki> forget I asked, it's netflix
2019-09-11T14:01:22 < jadew> I think this is the first movie I see on netflix that has full female nudity
2019-09-11T14:02:05 < jadew> it's like they screen them out

2019-09-11T14:13:06 < Cracki> Thorn, I say yes because there's no other way to get 60 watts
2019-09-11T14:13:07 < qyx> the built in IC will know

2019-09-11T14:15:42 < Cracki> the whole cable will glow :>
2019-09-11T14:15:51 < Cracki> like in avatar
2019-09-11T14:17:00 < Cracki> boss wanted to put an usb c jack on a new design... gave up because all those pins, even if most can be tied to ground, weren't worth it
2019-09-11T14:17:23 < Thorn> you can get type c connectors with fewer pins
2019-09-11T14:17:39 < Thorn> only power + CC or same + D+/D- but no usb3 data
2019-09-11T14:17:45 < Cracki> he's the cheap type, looking to save cents
2019-09-11T14:18:12 < Cracki> also he has two shops and if they don't have it in stock reliably, he isn't using it
2019-09-11T14:18:21 < Thorn> this looks useful to test cables https://www.aliexpress.com/item/4000077008310.html

2019-09-11T14:20:04 < Cracki> what's the common name for device-side connectors? jacks (vs plugs)?
2019-09-11T14:21:01 < Cracki> yeh I'm seeing usbc sockets (aha!) with 6 pins. i'll let boss know
2019-09-11T14:22:32 < Thorn> yes sockets
2019-09-11T14:24:30 < Cracki> digikey has double-digit-pinned usbc but nothing less, it seems
2019-09-11T14:24:37 < Cracki> at least our digikey
2019-09-11T14:26:45 < Cracki> and his other shop, schukat, appears to have no usb c sockets at all
2019-09-11T14:28:42 < Cracki> even digikey.com has only 14+ pins for any usb c
2019-09-11T14:30:11 < Thorn> check lcsc
2019-09-11T14:30:36 < Cracki> I'd bet they have it. aliex has them.
2019-09-11T14:32:44 < Cracki> lol he'd save a lot if he'd just take a step away from the "german engineering" mindset
2019-09-11T14:40:43 < Cracki> anyone got bad experiences with the "5 bucks / 100 pieces" usb c sockets off aliex or other chinese places?
2019-09-11T14:41:50 < Thorn> I'm using micro B from there without problems
2019-09-11T14:42:04 < Thorn> haven't tried type c yet
2019-09-11T14:47:41 < Cracki> it would sure be nice if usb sockets had standardized footprints you could rely on
2019-09-11T14:50:35 < Cracki> oh. the 6-pin ones are for usb PD only. no usb2 data pins.
2019-09-11T14:57:59 < dongs> there's a good chink type C socket with 14 pins
2019-09-11T14:58:06 < dongs> which has everything except highspeed lanes
2019-09-11T14:58:12 < dongs> and has wide traces for vcc/gnd
2019-09-11T14:58:34 < Cracki> yeh I've seen ~dozen-pin ones. not sure if boss had lost his patience with one of those or the full/dumb-pinned ones
2019-09-11T14:59:18 < Cracki> I'll need to get him away from this stable supply chain obsession

2019-09-11T15:58:15 < Thorn> wtf I just ordered 2 of them
2019-09-11T15:58:28 < Thorn> no cc wires in renders?
2019-09-11T15:58:39 < englishman> quickdongs is 9v I think but all closedsores shit? never used it
2019-09-11T15:59:01 < Thorn> it does say pd in the lot name
2019-09-11T15:59:04 < Cracki> quick, cancel the order
2019-09-11T15:59:07 < englishman> why are you shopping this awful chinese trash
2019-09-11T15:59:30 < Thorn> anyway I ordered socket breakouts, will test
2019-09-11T15:59:58 < englishman> oh it says pd 60w
2019-09-11T16:00:02 < englishman> you should be fine
2019-09-11T16:00:04 < Cracki> it does claim PD and 60 watts. if it doesn't do that when you have it in hand, you get your money back
2019-09-11T16:00:30 < englishman> that's 20v/3a but normally you find 20v/2.25a adapters for 45w
2019-09-11T16:00:39 < englishman> what do you need it for
2019-09-11T16:01:26 < englishman> $2 is pretty good
2019-09-11T16:01:47 < Cracki> maybe it does its own protocol between the plugs and needs only one wire for that.
2019-09-11T16:02:42 < Cracki> nvm, no 5th wire. maybe it's doing fuckery on the usb lines
2019-09-11T16:03:41 < Thorn> at least type a to µb ugreen cables are not awful trash
2019-09-11T16:04:04 < Thorn> hopefully type c aren't either
2019-09-11T16:06:42 < englishman> haven't seen a bad type c cable yet, the usb3 ones are huge tho

2019-09-11T17:35:46 < dongs> However, at the high end, the MPU-9250 VDDIO can be as high as 3.6V, whereas ICM-20948 VDDIO is limited to 1.95V. This may
2019-09-11T17:35:49 < dongs> entail redesign of the power supply to bring the VDDIO voltage in the range of ICM-20948.

2019-09-11T17:35:59 < dongs> why would you release a part with 1.8V VDDIO max
2019-09-11T17:38:05 < Thorn> "we want to support multiple i/o voltages as long as they are 1.8V"

2019-09-11T19:10:25 < zyp> what's the tl;dr on HRTimer?
2019-09-11T19:11:10 < Thorn> apparently just as powerful as TI C28 timers
2019-09-11T19:11:39 < Thorn> good enough for multiphase pwm

2019-09-11T19:12:03 < Thorn> dunno about that
2019-09-11T19:12:59 < zyp> N2HET runs it's own bytecode thing
2019-09-11T19:13:13 < zyp> so you can run logic directly on the timer

2019-09-11T19:14:33 < Thorn> the closest thing I've seen would be the SCTimer in lpc15xx

2019-09-11T19:31:30 < qyx> Thorn: multiphase pwm can be made with a common timer
2019-09-11T19:31:51 < qyx> asl long as current regulation is used
2019-09-11T19:32:28 < qyx> also hrtimer is old, F373 has it too iirc
2019-09-11T19:32:30 < Thorn> what about 3 sine waves 120° apart
2019-09-11T19:33:02 < qyx> sine wave is not pwm
2019-09-11T19:33:08 < qyx> thats a difference
2019-09-11T19:35:29 < Thorn> pwm'd sine waves
2019-09-11T19:42:04 < Thorn> why are they talkiing about builtin resistors in those type c to type c cables
2019-09-11T19:42:28 < Thorn> isn't it supposed to be pass through so that the 2 sides can negotiate with each other
2019-09-11T19:42:37 < Thorn> using PD
2019-09-11T19:43:24 < qyx> probably to mark the cable capability? how is it done?
2019-09-11T19:46:03 < Thorn> need to rtfm more
2019-09-11T19:46:35 < Thorn> also what is the difference between pd2.0 and pd3.0 (I found a cheap type c / pd2.0 v1.2 controller)
2019-09-11T19:52:09 < Thorn> so, mcu with usb, usb hub, 2x power switches, 2x type c controllers, 2x esd protection, 2x type c usb2.0 connectors, and that's a minimum
2019-09-11T19:52:17 < Thorn> suddenly ethernet is easier

2019-09-11T19:54:56 < Cracki> 3 sine waves 120 degs apart?
2019-09-11T19:55:19 < Cracki> yeh use the timer that can do channels 1-3 plus complementary channels
2019-09-11T19:55:43 < Cracki> then set up a sine table for duty cycles, then keep running through that
2019-09-11T19:58:19 < englishman> Thorn: you're not going to get 60W from Ethernet
2019-09-11T19:58:30 < englishman> and if you are, usb-c is probably easier and cheaper

2019-09-11T20:12:07 < zyp> as far as I'm reading the spec, each port can deliver up to 100W (and then there will be 71W available at the end device after cable losses)
2019-09-11T20:12:20 < englishman> cool, they have really stepped it up

2019-09-11T20:13:14 < zyp> for reference, af is 15.4W delivered, 12.95W after losses, at is 30W delivered, 25.5W after losses

2019-09-11T20:17:59 < Cracki> cable radiating 29 watts, nice
2019-09-11T20:18:16 < Cracki> (at max length)
2019-09-11T20:18:32 < catphish> morning
2019-09-11T20:21:38 < zyp> Cracki, if max length is 100m, that's 0.29 W/m
2019-09-11T20:21:54 < zyp> not super dramatic
2019-09-11T20:22:05 < Cracki> indeed not. sounds quite safe.
2019-09-11T20:22:32 < Cracki> maybe it's time to switch to alternating current to combat the losses
2019-09-11T20:22:48 < Cracki> to go into the kilovolts
2019-09-11T20:22:53 < zyp> compare to standard 230V circuits
2019-09-11T20:23:07 < zyp> e.g. I charge my car with 16A on 2.5mm2 conductors
2019-09-11T20:23:08 < Cracki> yeh std mains runs on way more copper tho
2019-09-11T20:23:21 < zyp> that's about 1.7 W/m per conductor
2019-09-11T20:23:52 < zyp> 3.4 W/m for a single phase run, 5.1 W/m for a three phase run
2019-09-11T20:24:26 < zyp> way more copper, but also a couple orders of magnitude more power
2019-09-11T20:27:45 < Cracki> I wonder what happens when you make an ethernet cable dissipate 1.7 W/m
2019-09-11T20:28:27 < Cracki> it'd get hotter than mains wiring because of all the shielding and isolation I'd bet
2019-09-11T20:29:31 < zyp> I'm not sure it makes a difference if it runs through conduit in an insulated wall
2019-09-11T20:30:45 < Cracki> good point
2019-09-11T20:31:45 < mawk> why would it combat loss Cracki ? because it's expensive to make high voltage DC ?
2019-09-11T20:31:57 < mawk> but that's not in the cable itself, that's at the PoE emitter and receiver
2019-09-11T20:32:22 < Cracki> someone tried explaining it to me once. skin effect or something. the copper not actually conducting.
2019-09-11T20:32:35 < mawk> yes
2019-09-11T20:32:42 < mawk> but skin effect makes AC worse than DC
2019-09-11T20:32:52 < mawk> it lowers the effective copper section
2019-09-11T20:32:53 < zyp> that's my impression too
2019-09-11T20:33:15 < zyp> skin effect and inductance causes increasing losses with frequency
2019-09-11T20:33:25 < zyp> whereas DC only has plain resistive losses
2019-09-11T20:33:26 < mawk> but indeed if you factor in the conversion losses of DC to DC maybe AC is better
2019-09-11T20:33:31 < mawk> you just need a transformer
2019-09-11T20:33:45 < Thorn> iirc if the 2 conductors are very close to each other you get something similar to skin effect even at DC
2019-09-11T20:33:56 < zyp> capacitance?
2019-09-11T20:34:08 < Cracki> that might be a historical advantage only. I remember hearing about high voltage dc-dc conversion being quite effective
2019-09-11T20:34:19 < Cracki> at least getting some research love
2019-09-11T20:35:15 < zyp> yeah, I think the traditional AC advantage was because transformers are easy
2019-09-11T20:35:30 < Cracki> otoh 48v isn't so good for connectors already. if someone unplugs the cable at higher voltages...
2019-09-11T20:35:37 < mawk> like free carrier displacement inside the wire Thorn ? because they are close
2019-09-11T20:36:03 < Thorn> something like that
2019-09-11T20:36:04 < Thorn> can't find it in google
2019-09-11T20:38:03 < Thorn> proximity effect probably

2019-09-11T22:13:09 < zyp> and last I tried using a bluetooth headset with a computer, that was a pretty unsatisfying experience, but that was also many years ago
2019-09-11T22:13:39 < kakimir> bluetooth audio is about useless without aptX
2019-09-11T22:13:50 < zyp> works fine with my phone, so I guess computer just had shitty bluetooth
2019-09-11T22:14:20 < zyp> hmm, I think my headset is just too old to have aptx
2019-09-11T22:14:43 < kakimir> bluetooth driver needs to have aptX support
2019-09-11T22:14:45 < zyp> I've got the MM550, I see there's a MM550-X with aptx, so I guess mine doesn't
2019-09-11T22:15:06 < zyp> but eh
2019-09-11T22:15:21 < zyp> it's old and fairly worn out, and I don't use it often nowadays
2019-09-11T22:15:45 < zyp> I'd get a qc35 or something if I used it often enough to justify one

2019-09-11T22:19:07 < zyp> if I were wearing headphones 8 hours a day I would have bought qc35 years ago
2019-09-11T22:19:29 < kakimir> maybe your host devices don't support or have aptx enabled Steffanx
2019-09-11T22:19:38 < Steffanx> it does kakimir

2019-09-11T22:21:43 < Steffanx> Oh now i remember. it's apt-x low latency it doesnt do.
2019-09-11T22:23:17 < kakimir> ?
2019-09-11T22:23:25 < kakimir> aptX but not low latency?

2019-09-11T22:32:12 < zyp> bought MX510 in ~2004, used it until I switched computers in 2008, then I went wireless for a while until one day battery was dead and I dug out MX510 because I needed a working mouse
2019-09-11T22:32:17 < zyp> and then I just kept using it since
2019-09-11T22:32:35 < Steffanx> y no magic apple mouse
2019-09-11T22:32:43 < zyp> I actually think I went through two wireless mice
2019-09-11T22:32:49 < zyp> Steffanx, yeah, that was one of them
2019-09-11T22:32:55 < Steffanx> i see
2019-09-11T22:33:43 < zyp> nice enough except battery bullshit
2019-09-11T22:34:09 < kakimir> logitech made mediocre wireless mouses between mx1000 and mxmaster
2019-09-11T22:34:50 < zyp> I got a M500 for work, works well enough
2019-09-11T22:35:08 < Steffanx> M500 shotgun.
2019-09-11T22:35:50 < kakimir> when do we play CS:GO Steffanx?
2019-09-11T22:36:20 < zyp> people still play that?
2019-09-11T22:36:35 < kakimir> dust2
2019-09-11T22:37:08 < kakimir> I mean I have not heard there would be new CS anytime soon
2019-09-11T22:37:31 < Steffanx> i never played CS kakimir.
2019-09-11T22:37:46 < kakimir> 1.6?
2019-09-11T22:37:49 < Steffanx> i only played TrueCombat:Elite 
2019-09-11T22:37:59 < kakimir> yes
2019-09-11T22:38:00 < Steffanx> which had a remake of dust: https://gamebanana.com/maps/125832
2019-09-11T22:38:45 < Steffanx> best game ever.
2019-09-11T22:38:45 < kakimir> is truecombat:elite still alive?
2019-09-11T22:38:49 < Steffanx> nah
2019-09-11T22:38:54 < Steffanx> some still play it
2019-09-11T22:38:54 < zyp> I've never played CS:GO, but I played the older versions a bit when I were a kid
2019-09-11T22:39:05 < zyp> wasn't any good at it though
2019-09-11T22:39:08 < kakimir> I think it suddenly just died around 2010 or so
2019-09-11T22:39:24 < zyp> 1.4-1.6-ish
2019-09-11T22:39:42 < Steffanx> Talking about TC:E kakimir? Not sure if it was 2010, but yeah it died
2019-09-11T22:39:44 < zyp> IIRC 1.6 was the first version on steam
2019-09-11T22:39:45 < Steffanx> but not really suddenly.
2019-09-11T22:39:57 < zyp> I played that, and a couple of the ones before steam
2019-09-11T22:40:54 < Steffanx> I want them to make games like C&C, Red Alert 1/2, maybe Generals, but they dont seem to do that no more.
2019-09-11T22:41:48 < zyp> red alert 2 was fun, never really liked generals that much
2019-09-11T22:42:49 < kakimir> I mean what is that bullshit that you cannot lay down or peek behind wall in CS
2019-09-11T22:42:54 < MrMobius> I had some kind of ini script for Red Aler where you could control what units each side can build and change all of their attributes
2019-09-11T22:43:09 < Steffanx> Yeah MrMobius
2019-09-11T22:43:13 < MrMobius> so you could make albert einstein a buildable unit and give him the same attack as a tesla coil but 10x faster
2019-09-11T22:43:18 < zyp> I remember I made some custom maps for red alert 2
2019-09-11T22:43:19 < Steffanx> Final Alert <3
2019-09-11T22:43:30 < Steffanx> 2
2019-09-11T22:45:41 < kakimir> BBL>
2019-09-11T22:46:01 < Steffanx> Goodbye mr kakimir
2019-09-11T22:46:29 < zyp> *yawn*
2019-09-11T22:46:49 < zyp> I'm reintegrating a bunch of workcode
2019-09-11T22:47:27 < zyp> used to have four simulink blobs on my platform, finally convinced coworker to bundle them all up in a single blob
2019-09-11T22:47:41 < zyp> so now I get to update everything that interfaces with it
2019-09-11T22:47:50 < Steffanx> Dont you have like 5 months of parental leave time in norway?
2019-09-11T22:48:58 < zyp> more like 12, but there's conditions on taking the leave
2019-09-11T22:49:07 < Steffanx> 12 weeks that is?
2019-09-11T22:49:13 < zyp> doesn't really matter, I'm technically using my vacation time now
2019-09-11T22:49:18 < zyp> no, months, like 50 weeks
2019-09-11T22:49:22 < zyp> split between both parents
2019-09-11T22:49:23 < Steffanx> wut
2019-09-11T22:49:34 < Steffanx> damn
2019-09-11T22:49:47 < zyp> but I might not be able to use any of it :p
2019-09-11T22:53:50 < Steffanx> At least it makes you feel important :(0
2019-09-11T22:53:53 < Steffanx> :) 
2019-09-11T22:54:21 < zyp> anyway, my employer is pretty flexible regarding both working hours and working from home, so I figure I can be flexible in return, getting shit that needs to be done done
2019-09-11T22:54:42 < zyp> so I'm working part time from home this week
2019-09-11T22:55:00 < zyp> hence why I'm working at this hour :p
2019-09-11T22:55:57 < Steffanx> ~22.00 is a good working hour
2019-09-11T22:56:03 < zyp> also, instead of spending my remaining four weeks of vacation all at once, I can instead work part time for a longer period
2019-09-11T22:56:35 < zyp> yeah, I remember when I were a student I were always more productive in the evenings than the mornings
2019-09-11T22:57:32 < fenugrec> any interest here in repair videos ? I'm fixing a 3ph servo drive board, probably going to film some of it
2019-09-11T22:57:52 < Steffanx> Will you talk like rossman?
2019-09-11T22:58:00 < Steffanx> louis.
2019-09-11T22:58:11 < Steffanx> or more like dave?
2019-09-11T22:59:07 < fenugrec> not rossman, although I could complain about the board manufacturer
2019-09-11T23:00:39 < Steffanx> Anyway, idk. i dont watch many repair vids. but perhaps...
2019-09-11T23:01:08 < fenugrec> hehe I don't sound like Dave either, you risk being sorely disappointed
2019-09-11T23:01:32 < Steffanx> Nah you are keeping the expectations low.
2019-09-11T23:02:16 < zyp> hmm, fucking autogenerated struct member names have some random-ish letter suffix and apparently they changed
2019-09-11T23:02:40 < zyp> so even though the new wrapper model mostly exports same buses as before, I need to rename that bullshit
2019-09-11T23:04:39 < zyp> also somehow not all names have that suffix, idk what the point is
2019-09-11T23:05:08 < Steffanx> auto-generated code that is inconsistent? Fun fun.
2019-09-11T23:06:11 < zyp> well, it's been consistent before, I guess it's based on a hash or some shit and now the change was big enough to change the hash input

2019-09-11T23:12:58 < zyp> oh well, this is fairly dumb search and replace work, done with one of the two files that maps network signals to simulink buses
2019-09-11T23:13:39 < zyp> and then it'll be the task that actually runs the models
2019-09-11T23:16:19 < jadew> who was making a pnp machine?
2019-09-11T23:16:23 < jadew> catphish, was that you?
2019-09-11T23:16:31 < catphish> jadew: yes
2019-09-11T23:16:38 < jadew> how did it turn out?
2019-09-11T23:16:42 < catphish> jadew: but i essentially failed
2019-09-11T23:16:55 < jadew> oh, what happened?
2019-09-11T23:17:00 < catphish> jadew: well, it was interesting, but ultimately not useful
2019-09-11T23:17:01 < Steffanx> no you gave up, that's something else as failing
2019-09-11T23:17:37 < catphish> it picked, it placed, i couldn't be bothered to finish it and build feeders
2019-09-11T23:17:51 < jadew> I see
2019-09-11T23:18:00 < catphish> ultimately, it seemed like the setup effort was just too great for it to be useful
2019-09-11T23:18:13 < catphish> was a fun project though
2019-09-11T23:18:25 < jadew> you mean to set it up for a job?
2019-09-11T23:18:36 < Cracki> screw feeders, go all in with the optics and have it pick up birdfeed from a loose tray
2019-09-11T23:19:02 < catphish> jadew: yes, setting up a job
2019-09-11T23:19:10 < zyp> catphish, you wouldn't have a need for 100x STM32L052R8T6 for any of your projects? :p

2019-09-11T23:20:45 < catphish> zyp: sounds unlikely :) i've never produced more than 1 of anything ;)
2019-09-11T23:21:09 < zyp> no wonder you didn't find any need for a P&P :p
2019-09-11T23:21:11 < catphish> my nfc was l0, but i forget which one, and i was too lazy to design a case or software for it
2019-09-11T23:21:46 < zyp> I fucked up the BOM for my new nfc batch and got the 64 pin variant instead of the 48 pin variant
2019-09-11T23:21:47 < catphish> zyp: this is my problem, i never find the interest in finishing any of my designs :)
2019-09-11T23:21:55 < catphish> oops
2019-09-11T23:21:55 < zyp> so now I have a pile of the 64 pin ones to get rid of :p
2019-09-11T23:22:43 < catphish> zyp: my nfc only uses 32 pin :)
2019-09-11T23:23:05 < catphish> https://i.imgur.com/o4ZSdrO.jpg
2019-09-11T23:23:19 < zyp> ah
2019-09-11T23:23:34 < zyp> IMO 32 pin is not worthwhile
2019-09-11T23:23:56 < catphish> it's worthwhile if it's cheap and all you need i guess
2019-09-11T23:23:57 < zyp> last I checked they were more expensive and/or less available than 48 pin and consumes same area
2019-09-11T23:24:34 < catphish> device in its case, i'm glad i got better at cleaning flux https://i.imgur.com/wWqc9K5.jpg
2019-09-11T23:24:52 < zyp> one could argue they are easier to solder, but next to the qfn that matters fuckall
2019-09-11T23:25:09 < catphish> true, never had a problem soldering any of the stm32
2019-09-11T23:25:18 < zyp> if you can't solder 0.5mm pitch qfp, forget about qfn :p
2019-09-11T23:25:42 < catphish> the qfn was hell because of too much solder on the centre pad
2019-09-11T23:26:08 < catphish> hot plate works great, but qfn loves to float
2019-09-11T23:26:19 < zyp> I've mostly gotten burned by shitty footprints
2019-09-11T23:26:43 < jadew> I want a pnp machine that can do 0402
2019-09-11T23:26:45 < zyp> qfn behaves nicely with a decent footprint, behaves like shit with a terrible one
2019-09-11T23:26:55 < jadew> doing that stuff by hand is just annoying
2019-09-11T23:27:04 < jadew> it's like handling specks of dirt
2019-09-11T23:27:33 < zyp> IMO placing 0402 is easy enough, but you need to have good control of the paste application
2019-09-11T23:27:37 < catphish> yeah my problem was the kicad footprint, huge aperture on the paste template on the centre pad :(
2019-09-11T23:27:44 < zyp> otherwise they tombstone too easily
2019-09-11T23:28:02 < zyp> catphish, nah, I'm not talking about stencil, I'm talking about the actual pads
2019-09-11T23:28:03 < catphish> with a solder paste template, i found all passives trivial
2019-09-11T23:28:05 < jadew> zyp, by that you mean not too much paste?
2019-09-11T23:28:16 < zyp> jadew, or just evenly applied
2019-09-11T23:28:19 < catphish> zyp: my problem was the template, too much paste on the pad
2019-09-11T23:28:32 < zyp> sure
2019-09-11T23:28:40 < catphish> large pad is fine, but needs very little paste
2019-09-11T23:29:17 < catphish> though that's an assumption
2019-09-11T23:29:26 < catphish> i've never done it right
2019-09-11T23:29:37 < Cracki> don't get confused, thermal pads like less paste, but 0402 birdfeed is pretty tolerant to how much paste the pads get
2019-09-11T23:29:49 < zyp> https://bin.jvnv.net/file/QW7ZG.png <- here's a board I did many years ago, made three of them
2019-09-11T23:30:04 < zyp> U8 (in the middle of the board) soldered nicely on all three of them
2019-09-11T23:30:23 < zyp> the other qfn in the upper left corner barely worked on one IIRC
2019-09-11T23:30:24 < catphish> oh yeah, passives are trivial
2019-09-11T23:30:37 < catphish> i use 0603, never had an issue
2019-09-11T23:30:38 < Cracki> 0402 is standard even for the "cheap" pnps
2019-09-11T23:30:55 < zyp> Cracki, just prone to tombstoning
2019-09-11T23:30:59 < zyp> is my experience
2019-09-11T23:31:01 < Cracki> biggest worry should be that the nozzle isn't too large :>
2019-09-11T23:31:07 < Cracki> good point yes
2019-09-11T23:31:17 < catphish> my nozzle is probably much too large
2019-09-11T23:31:31 < zyp> I still do 0603 on everything because I got fed up with 0402 tombstoning like eight years ago :p
2019-09-11T23:31:32 < Cracki> I think we "fixed" tombstoning by having them mashed a little more into the paste
2019-09-11T23:31:43 < zyp> even though I don't assemble stuff myself much anymore
2019-09-11T23:31:47 < Cracki> or whoever did the postbake control just dealt with it
2019-09-11T23:32:16 < catphish> i've only ever assembled with tweezers, so meh
2019-09-11T23:32:32 < jadew> I do manual pnp with a vacuum pump
2019-09-11T23:32:58 < jadew> zyp, who does assembly for you? dongs?
2019-09-11T23:32:59 < catphish> that sounds nice, tweezers are actually suck
2019-09-11T23:33:17 < jadew> catphish, I still use them for heavy components
2019-09-11T23:33:29 < zyp> jadew, yes, or people he knows
2019-09-11T23:33:32 < Cracki> wat? I'd use the cup for big chips and tweezers for small stuff
2019-09-11T23:34:20 < Cracki> is a manual pump for small components even feasible?
2019-09-11T23:34:29 < jadew> Cracki, the pump is not manual
2019-09-11T23:34:42 < Cracki> no cup that can compensate non-vertical approach
2019-09-11T23:34:45 < jadew> just the pnp part is
2019-09-11T23:34:53 < Cracki> well yes it's motor-operated but hand-moved
2019-09-11T23:34:58 < jadew> yeah
2019-09-11T23:35:05 < jadew> I move them with a bent needle that I made
2019-09-11T23:35:56 < jadew> http://5.12.176.60/stuff/needle.jpg
2019-09-11T23:36:31 < jadew> I used a medical needle and filed it into that shape
2019-09-11T23:36:37 < Cracki> how gentle of a bend? or did ya fill it to keep it from collapsing at the bend?
2019-09-11T23:36:43 < Cracki> ah filed

2019-09-11T23:42:37 < jadew> too bad
2019-09-11T23:42:42 < Cracki> aaah pls fix lighting. incident angle must be a lot closer to the horizon. you have near noon light there, which causes the reflections
2019-09-11T23:43:09 < catphish> yeah the lighting wasn't great, needed diffusing or angling
2019-09-11T23:43:22 < catphish> the camera was mounted in the back of he head: the samera 
2019-09-11T23:43:23 < Cracki> diffusion doesn't help if it's still in view of that mirror

2019-09-11T23:43:41 < Cracki> basically, move reflections off-picture, so lights must be outside that viewing pyramid
2019-09-11T23:43:57 < Cracki> glad that there's software already
2019-09-11T23:44:07 < catphish> openpnp is cool
2019-09-11T23:44:15 < Cracki> I wonder how bad their code is

2019-09-11T23:45:46 < catphish> it's quite custimizable

2019-09-11T23:46:00 < catphish> the user is expected to build opencv flows
2019-09-11T23:46:19 < catphish> haven't seen that
2019-09-11T23:46:29 < catphish> anyway, i gave up on this long enough
2019-09-11T23:46:44 < catphish> someone with more money than me can build my boards

2019-09-11T23:47:34 < jadew> they're not much different from a 3d printer
2019-09-11T23:48:09 < catphish> there are some i think for a few 1000s
2019-09-11T23:48:19 < jadew> yeah, but that's not 500
2019-09-11T23:48:52 < catphish> even my diy device was around 1000!

2019-09-11T23:52:09 < aandrew> https://www.aliexpress.com/item/4000056182909.html  <-- if I'm reading that correctly, do I supply it with 20V and it will allow whatever I plug in to USB-C to get 5V-20V for charging?
2019-09-11T23:52:32 < Thorn> >Spoof Scam
2019-09-11T23:52:39 < Thorn> sounds legit
2019-09-11T23:53:43 < aandrew> I am thinking it might be the other way, that you plug a USBC power supplying device into it and it says "yeah gimme max volts/amps"
2019-09-11T23:53:44 < Thorn> the 14 pad QFN is probably FUSB302
2019-09-11T23:54:02 < zyp> I think aandrew is right
2019-09-11T23:54:25 < zyp> considering the variant with the A socket
2019-09-11T23:54:46 < Thorn> is that an inductor next to the stm32?
2019-09-11T23:55:05 < aandrew> I'm right which way, that it negotiates max volts/amps and accepts voltage, not supplies it
2019-09-11T23:55:09 < aandrew> Thorn: I think it's a button
2019-09-11T23:55:48 < aandrew> I'm just looking for a little circuit that does the PD shit and creates a supply of whatever the other end wants 
2019-09-11T23:56:09 < aandrew> just the circuit though and maybe the buck reg, not a wall wart (I want to hoook it up to a battery bank and have it supply)
2019-09-11T23:56:31 < aandrew> failing with my search terms though
2019-09-11T23:57:13 < Thorn> oh lol they released the famous tp4056 board with type C
2019-09-11T23:57:27 < aandrew> yep
2019-09-11T23:57:34 < aandrew> I have a bunc hof those, not C though
2019-09-11T23:59:51 < aandrew> it seems the "negotiate pd" which accepts voltage are called "trigger" circuits

2019-09-12T00:01:59 < catphish> USB-PD is awesome
2019-09-12T00:02:05 < aandrew> hm, tps65987 looks like the right IC

2019-09-12T00:02:40 < Thorn> aandrew: that's most likely an overkill
2019-09-12T00:03:02 < aandrew> well I'd need it to be able to tell whatever is doing the power supplying what voltage to output
2019-09-12T00:04:05 < Thorn> something simpler like that fusb302 should do the trick
2019-09-12T00:07:04 < grummund> does dfu-util that work over uart?  afaics stm32f030 has no usb.
2019-09-12T00:07:45 < aandrew> FUSB302 can act as the supply/source?
2019-09-12T00:08:01 < aandrew> looks like it, I think

2019-09-12T17:28:15 < Ecco> Hey :)
2019-09-12T17:28:27 < Ecco> For some reason I think I locked myself out of an STM32G0
2019-09-12T17:28:38 < Ecco> Flash code enters STOP mode really early on boot
2019-09-12T17:28:50 < Ecco> (so I can't attach a debugger)
2019-09-12T17:29:07 < Ecco> and for some reason I can't seem to get it to boot on the internal bootloader
2019-09-12T17:30:02 < Thorn> Ecco: use st-link, enable connect under reset
2019-09-12T17:30:11 < Thorn> (or use j-link which does it automagically if it can't connect normally)
2019-09-12T17:31:59 < Ecco> Indeed, that's a good suggestion, thanks
2019-09-12T17:32:12 < Ecco> Yet, how comes I can't get the MCU to boot on the system memory?
2019-09-12T17:33:15 < Thorn> is it entering the bootloader at all?
2019-09-12T17:33:26 < Ecco> well, no, it's running code from Flash memory
2019-09-12T17:34:08 < Thorn> I'm not sure if g0 has option bytes or whatever to override boot0 but that's one thing to check
2019-09-12T17:36:07 < Ecco> I'll check. Do you know if it's possible to do connect-under-reset using openocd?
2019-09-12T17:36:43 < Thorn> it is afaik but I don't remember off hand how to

2019-09-12T18:58:26 < Cracki> dongs, I'd also be wary of flimsy constructions like the ultimaker 2. the rods bent easily, wasn't especially fond of the print bed either
2019-09-12T18:58:59 < Cracki> oh and the stepper drivers... pick something good or upgradeable, and nothing atmega-based for the mainboard.

2019-09-12T19:02:12 < Cracki> sadly, the old stratasys at the local fablab still has better prints than what they get done with ultimaker 3 and others... probably because the stratasys doesn't let them fuck up the parameters.

2019-09-12T21:50:18 < Steffanx> only for moneyed westeners.
2019-09-12T21:51:56 < qyx> I have a clear L053
2019-09-12T21:52:16 < qyx> should it be visible in lsusb?
2019-09-12T21:52:34 < qyx> I know I could rtfm..
2019-09-12T21:56:48 < qyx> wait what, there is no USB mentioned in the AN2606
2019-09-12T21:58:40 < qyx> so basically fukit, there is no way I could flash a blinky led to this thing
2019-09-12T21:58:50 < qyx> I forgot mini-B cable for stlink

2019-09-12T23:00:27 < jadew> somehow my PC restarted for updates (even tho this behaviour was disabled)
2019-09-12T23:00:43 < jadew> and I've lost all the tabs I had open with "suitable components"
2019-09-12T23:00:47 < jadew> from the day before
2019-09-12T23:02:49 < jadew> I spent at least two hours on that
2019-09-12T23:04:09 < Thorn> I copy all interesting urls into m$ onenote
2019-09-12T23:04:24 < Thorn> + session addon for chrome

2019-09-12T23:09:41 < jadew> I keep notes too, but sometimes I don't :)
2019-09-12T23:14:56 < specing> Thorn: can you accurately measure the depth of the micro-usb plug?
2019-09-12T23:15:06 < specing> like, to +- 0.05 mm?
2019-09-12T23:15:15 < qyx> what browser doesn't offer you tam restore?
2019-09-12T23:15:20 < qyx> *tab
2019-09-12T23:15:25 < jadew> qyx, chrome apparently
2019-09-12T23:15:30 < qyx> poor jadew 
2019-09-12T23:15:44 < Thorn> specing: may caliper is borked. I believe it's 5.0mm
2019-09-12T23:16:11 < specing> Thorn: it can't be 5.0mm
2019-09-12T23:16:19 < specing> all the cables I have are 5.4 - 5.8 mm
2019-09-12T23:21:16 < Steffanx> It's because Ada gives you extra overhead.
2019-09-12T23:25:31 < specing> Lol
2019-09-12T23:26:04 < specing> Actually less, since the compiler knows more about what the programmer meant
2019-09-12T23:29:29 < qyx> adapter speed: 300 kHz
2019-09-12T23:29:33 < qyx> such slow
2019-09-12T23:30:01 < qyx> at least the L053 is alive
2019-09-12T23:35:32 < Cracki> jadew, chrome can do "bookmark all tabs" for a window... and it can restore your session. it has even become reliable.
2019-09-12T23:35:47 < jadew> Cracki, not this time, not sure why
2019-09-12T23:35:49 < Cracki> you gotta set it to restore session tho
2019-09-12T23:35:56 < Cracki> also... win10?
2019-09-12T23:36:01 < Cracki> there are ways to make it stfu
2019-09-12T23:36:02 < jadew> yeah, win 10
2019-09-12T23:36:08 < jadew> I think windows just asked it to close
2019-09-12T23:36:14 < jadew> in which case it wouldn't have had anything to restore
2019-09-12T23:36:18 < jadew> because it didn't crash
2019-09-12T23:36:23 < jadew> it just... closed itself
2019-09-12T23:36:27 < Cracki> w10privacy is what someone recommended to me. it's a mess of a "gui" tho
2019-09-12T23:36:45 < qyx> ff restores tab for me even if I close it
2019-09-12T23:36:52 < Cracki> nah, when windows closes chrome, chrome saves the session. I've never had problems with chrome because windows decided to reboot
2019-09-12T23:36:54 < jadew> I don't know why it rebooted, I have that setting enabled in the policies
2019-09-12T23:36:54 < qyx> but it has to be set
2019-09-12T23:37:08 < Cracki> yes, you must set the behavior. otherwise you get a blank chrome every time you start it
2019-09-12T23:37:15 < Cracki> w10 ignores policies
2019-09-12T23:37:18 < qyx> the same in firefox
2019-09-12T23:37:25 < Cracki> it ignores the "no fucking bing web search" policy too
2019-09-12T23:37:31 < jadew> well, yeah, I don't like it to remember the last session
2019-09-12T23:37:35 < Cracki> you have to block it in the firewall rules
2019-09-12T23:37:38 < Cracki> wat
2019-09-12T23:37:40 < Cracki> you do NOT?
2019-09-12T23:37:56 < qyx> I have a tab counter
2019-09-12T23:38:01 < jadew> no... if I decide to shut down and I haven't bookmarked stuff, it means I didn't care about it
2019-09-12T23:38:05 < qyx> if it reaches 1000, I have to start over
2019-09-12T23:38:14 < jadew> I don't need that garbage showing up when I turn it on again
2019-09-12T23:38:35 < Cracki> chrome has history
2019-09-12T23:38:47 < Cracki> it might even remember the previously open tabs as tabs you can re-open
2019-09-12T23:38:52 < jadew> Cracki, yeah, but I've visited maybe 200 datasheets or more
2019-09-12T23:39:00 < jadew> and only kept like... 3
2019-09-12T23:39:23 < Cracki> I have a screenshot task every 5 minutes
2019-09-12T23:39:32 < jadew> what for?
2019-09-12T23:39:33 < Cracki> helps me keep track of what I do
2019-09-12T23:39:35 < qyx> lol
2019-09-12T23:39:39 < Cracki> exactly for such occasions
2019-09-12T23:39:53 < jadew> sounds a bit excessive 
2019-09-12T23:40:10 < Cracki> if I work on an email, post, article, whatever, and it's in my screenshots, it's written in stone
2019-09-12T23:40:12 < Cracki> why tho
2019-09-12T23:40:18 < Cracki> the storage costs nothing
2019-09-12T23:40:55 < Cracki> i agree, it's a brute force thing to do but eh
2019-09-12T23:41:03 < jadew> do you turn it off when you watch porn, or do you use it to remember what movie you got off off two times ago?
2019-09-12T23:41:14 < Cracki> I'd do 24/7 audio recordings too if I had a mobile device that had the battery for it

2019-09-12T23:42:03 < Cracki> _some_ stuff I delete
2019-09-12T23:42:23 < Cracki> I should maybe move that stuff into encrypted disks regularly
2019-09-12T23:42:52 < Cracki> think of it as insurance
2019-09-12T23:43:03 < Cracki> it's a good idea to record calls too, if it's legal

2019-09-12T23:44:53 < jadew> that tool was great
2019-09-12T23:44:54 < Cracki> i know
2019-09-12T23:45:00 < Cracki> fuck google with a chainsaw
2019-09-12T23:45:07 < jadew> it's legal in here, but you can only use it to defend yourself in court
2019-09-12T23:45:32 < Cracki> louis has some call server set up and routes everything through that
2019-09-12T23:45:51 < Cracki> it also helps to run a rooted android
2019-09-12T23:47:28 < Thorn> type A to type C is a really interesting situation. why didn't. they include a special Rp value for this case
2019-09-12T23:48:04 < Thorn> the cable maker basically has to guess how much current the host can supply which makes no sense
2019-09-12T23:49:12 < Thorn> if there was an Rp value = "type-A" then the UFP could use BCD1.2 to negotiate with the host 
2019-09-12T23:49:23 < Cracki> cashier is a hard job. I give her a stack of 10 bars of chocolate. she counts 12.
2019-09-12T23:49:46 < Cracki> cable maker can play it safe
2019-09-12T23:50:06 < catphish> what kind of monster hands a cashier a stack of products and doesn't tell them how many are in the pile?
2019-09-12T23:50:15 < Cracki> you make it sound as if there is no negotiation for type A, even when it's usb 3.0/3.1
2019-09-12T23:50:30 < jadew> catphish, I rarely count the stuff I take off the shelf
2019-09-12T23:50:39 < jadew> and they have to count them anyway
2019-09-12T23:50:51 < jadew> otherwise you can cheat them
2019-09-12T23:50:54 < Cracki> every time I give her a stack, she throws me the items individually and I have to shove them quickly into my bag
2019-09-12T23:51:08 < jadew> if they trusted you, the cashiers wouldn't be there
2019-09-12T23:51:14 < Cracki> you gotta watch them like a hawk, check that they counted right
2019-09-12T23:51:24 < Cracki> low trust society! no self checkout!
2019-09-12T23:51:48 < jadew> we started having that now
2019-09-12T23:51:50 < Cracki> especially in a place where lots of drunk shits walk in and buy more booze
2019-09-12T23:52:01 < Cracki> haha your country will survive
2019-09-12T23:52:09 < Cracki> mine might not
2019-09-12T23:52:09 < jadew> there are shops where you can scan your stuff directly from your phone
2019-09-12T23:52:15 < jadew> and you just pay on your way out
2019-09-12T23:53:17 < jadew> romania is more tame since we joined the EU
2019-09-12T23:53:23 < Cracki> they should pick one in 100 customers to check if the goods match the slip, and if they do it's all free
2019-09-12T23:53:30 < jadew> all the thieves went to france and the UK
2019-09-12T23:53:32 < Cracki> that would raise compliance like fuck

2019-09-12T23:54:34 < Cracki> 1% free stuff
2019-09-12T23:55:03 < Cracki> it's like lottery. the most tempted ones to steal are those who love lottery
2019-09-12T23:56:26 < Cracki> or make it 10% off or something that *immediately* rewards good behavior

2019-09-13T00:06:15 < BrainDamage> most romanians went to italy and spay, not france nor germany

2019-09-13T00:06:33 < Steffanx> Because reading from a screen sucks arse
2019-09-13T00:06:41 < Steffanx> + all the distractions
2019-09-13T00:07:22 < BrainDamage> in fact here there's strong prejudice against romanians as consequence
2019-09-13T00:07:45 < BrainDamage> there's 'rom camps' at the edge of the cities in pretty filthy conditions
2019-09-13T00:07:52 < Steffanx> And I yet have to see a okish epaper reader that works with books in pdf form properly

2019-09-13T00:09:17 < jadew> Steffanx, I have not problem reading from a computer screen and if I'm on a plane or something, I'm fine reading from my phone
2019-09-13T00:09:28 < jadew> the advantage is that you can take your entire library with you
2019-09-13T00:09:39 < jadew> as opposed to just a couple of books you can carry
2019-09-13T00:10:16 < Steffanx> Especially on a computer there are waaay too many distractions
2019-09-13T00:11:19 < jadew> BrainDamage, I wonder how much of that pie chart is gypsies
2019-09-13T00:11:58 < Cracki> "romanians" is the politically correct way to say gypsies
2019-09-13T00:12:10 < Cracki> at least in countries that can't tell the difference :P
2019-09-13T00:12:23 < Cracki> btw, ebook readers these days have amazing displays
2019-09-13T00:12:45 < Cracki> also user interaction has become better

2019-09-13T00:13:25 < Cracki> because you wanted to rise early tomorrow?

2019-09-13T00:13:43 < jadew> I want to go back
2019-09-13T00:14:02 < Cracki> do it? part-time college maybe?

2019-09-13T00:15:09 < BrainDamage> but this is a pdf
2019-09-13T00:15:15 < BrainDamage> everything is rendered perfectly
2019-09-13T00:15:23 < BrainDamage> including math glyphs
2019-09-13T00:15:39 < jadew> BrainDamage, it looks amazing
2019-09-13T00:16:00 < Cracki> 'go back' implies you have some degree or finished some courses already, so no mandatory math classes to do while deciding
2019-09-13T00:16:19 < BrainDamage> the screen res has 450 dpi
2019-09-13T00:16:52 < Cracki> nice
2019-09-13T00:18:02 < BrainDamage> and it's probably stuff you don't care about, but it comes with root from the factory, as well as the source code for everything
2019-09-13T00:18:08 < Cracki> 56 micron. at 30 centimeters that's 0.6 arc minutes, below the eye's typical res

2019-09-13T00:21:58 < Steffanx> Idk
2019-09-13T00:25:34 < Steffanx> Anyway, what mcu do you have grummund? On some pages it shows the "System View Description" in the resource tab on the pages for the mcu. 
2019-09-13T00:27:44 < grummund> this one is stm32f030, before i was using stm32f103 and somewhere had the svd file for it but now it's lost...
2019-09-13T00:28:12 < grummund> it's for loading in the debugger to resolve the peripheral registers
2019-09-13T00:28:32 < Steffanx> https://www.st.com/resource/en/svd/stm32f0_svd.zip ?
2019-09-13T00:30:06 < grummund> wtf? thanks, how did you find that?
2019-09-13T00:30:39 < Steffanx> i went to the page for a random f0, went to the resource tab, cltr+f "system view". Click :P
2019-09-13T00:31:00 < Steffanx> it seesm you can get the l1/f4 etc by just changing that part in the url.
2019-09-13T00:33:22 < grummund> yeah, thanks.  listed under "HW Model, CAD Libraries & SVD"
2019-09-13T00:36:02 < grummund> ST turned me down for a hands-on workshop.
2019-09-13T00:37:27 < grummund> "To provide the best learning environment, we have limited this event to engineers with basic experience on microprocessor and embedded Linux environment. We are unfortunately unable to allocate you a place in our session ... This is either due to the fact that our capacity has been reached or that our understanding of your expectations from this training is not in-line with the content of this workshop."
2019-09-13T00:37:33 < grummund> :-(
2019-09-13T00:39:08 < Steffanx> You didnt sign up from a work address. or dont you work in the embedded/whatever related business at all?
2019-09-13T00:39:34 < karlp> or , like they said, it was full?
2019-09-13T00:39:45 < Steffanx> or that.
2019-09-13T00:40:14 < grummund> or maybe cos i answered honestly about embedded linux experience
2019-09-13T00:41:34 < Steffanx> And that was? "None"? 
2019-09-13T00:41:37 < Thorn> >To ensure safety in case the I2C interface fails, a TCPC sourcing VBUS higher than 5V shall autonomously stop sourcing VBUS if the Sink is detached.
2019-09-13T00:41:40 < grummund> yep ;-)
2019-09-13T00:41:42 < Steffanx> Should try again and lie
2019-09-13T00:42:02 < grummund> it's prolly fully booked now
2019-09-13T00:42:36 < jadew> bu hu
2019-09-13T00:42:43 < jadew> I missed the admission session to college
2019-09-13T00:42:45 < Steffanx> Was it some mp1 workshop?
2019-09-13T00:42:58 < karlp> Cracki: wheres your source on cthe "corrext" term for roma being romanian? wat?!
2019-09-13T00:43:00 < grummund> yes
2019-09-13T00:43:31 < Steffanx> Romas are from Romania right? :P
2019-09-13T00:43:43 < jadew> Steffanx, funny
2019-09-13T00:44:13 < jadew> believe it or not, some of them are cool people
2019-09-13T00:44:28 < Steffanx> i dont know any of em
2019-09-13T00:44:47 < jadew> I do, but odds are the ones that you might meet are not so nice
2019-09-13T00:45:26 < Thorn> are they EEs
2019-09-13T00:46:19 < jadew> not the ones I've met
2019-09-13T00:46:24 < Steffanx> i mean  "Romani people in Romania" how can they not be from romania. ;)
2019-09-13T00:48:04 < mawk> the last rom I interacted with tried to steal my shit
2019-09-13T00:48:09 < mawk> with the petition trick
2019-09-13T00:48:20 < jadew> what petition trick?
2019-09-13T00:48:20 < mawk> or maybe they wanted a donation for their fake deaf people association
2019-09-13T00:48:22 < mawk> either of these
2019-09-13T00:48:32 < mawk> they come to you with a big paper to sign for a phony association
2019-09-13T00:48:39 < mawk> and they cry and everything to get a donation
2019-09-13T00:48:47 < jadew> right
2019-09-13T00:49:24 < Steffanx> oh those poor woman walking around near the eifel tower etc. mawk?
2019-09-13T00:49:29 < mawk> yeah
2019-09-13T00:49:32 < mawk> or at the airport
2019-09-13T00:49:36 < mawk> it works best on tourists
2019-09-13T00:49:42 < Cracki> it appears that using quotes and the word "politically" is insufficient to convey a message reliably
2019-09-13T00:50:02 < mawk> there's also the tuktuk trick, where they make you pay 4× the indicated price
2019-09-13T00:50:02 < jadew> speaking of that, we went once to visit the eifel tower and decided to rest on the grass
2019-09-13T00:50:10 < Cracki> are you talking about cologne new year's eve?
2019-09-13T00:50:23 < jadew> 2 minutes later, the people I was with were having an argument with some gypsies lol
2019-09-13T00:50:24 < mawk> they make a trip to and back some monument, it says 20€ on the paper, then they say it was 20€ per person for a single trip, so 80€
2019-09-13T00:50:34 < Cracki> has the eiffel tower been surrounded by a glass wall yet? I saw plans for that
2019-09-13T00:50:38 < mawk> yes
2019-09-13T00:50:40 < mawk> I saw it
2019-09-13T00:50:44 < Cracki> excellent
2019-09-13T00:50:47 < jadew> really?
2019-09-13T00:50:50 < jadew> why is that?
2019-09-13T00:50:52 < mawk> it's not that tall
2019-09-13T00:50:55 < Cracki> you can imagine ;)
2019-09-13T00:50:55 < mawk> for terrorist attacks
2019-09-13T00:51:09 < jadew> to contain the blast and only kill the people inside the glass walls?
2019-09-13T00:51:13 < mawk> lol
2019-09-13T00:51:17 < mawk> it's for car attacks I think
2019-09-13T00:51:21 < Cracki> nah, to keep loitering unwanted people away from the only thing that attracts tourist money
2019-09-13T00:51:24 -!- renn0xtk9 [~max@2a02:810d:1540:2448:4caa:d8ea:39a2:4e15] has quit [Quit: Konversation terminated!]
2019-09-13T00:51:25 < mawk> and there is police filtering to get inside the zone
2019-09-13T00:51:39 < mawk> so if you're bearded with a ak-47 coming from under your jacket you can't get in
2019-09-13T00:51:54 < Cracki> fuck gilette I'm never shaving again
2019-09-13T00:51:59 < mawk> lol
2019-09-13T00:52:13  * Cracki shaves with an axe
2019-09-13T00:52:22 < Cracki> *ahem* machete
2019-09-13T00:53:05 < jadew> a couple of months ago when we went to disnayland paris, part of the airport was locked down because someone forgot a bag
2019-09-13T00:53:17 < mawk> yeah it happens in train stations too
2019-09-13T00:53:23 < mawk> bomb squad comes and explodes the bag
2019-09-13T00:53:35 < mawk> paralyzes the whole traffic for half a day
2019-09-13T00:53:44 < jadew> I'd say the terrorists have won
2019-09-13T00:53:45 < mawk> but that's everywhere I guess
2019-09-13T00:53:48 < mawk> yeah
2019-09-13T00:53:52 < mawk> everyone is scared
2019-09-13T00:53:55 < jadew> yeah
2019-09-13T00:53:59 < qyx> anyone used L1/L0 lcd?
2019-09-13T00:54:02 < mawk> defence weapons sales must have seen a big growth
2019-09-13T00:54:13 < mawk> also weapon possession permits
2019-09-13T00:54:16 < mawk> I got one myself too lol
2019-09-13T00:54:22 < mawk> terrorists won on me
2019-09-13T00:54:59 < Steffanx> you know you cant take it to dutchland uh?
2019-09-13T00:55:12 < mawk> yes I can
2019-09-13T00:55:13 < mawk> I have a plan
2019-09-13T00:55:18 < mawk> I just need the dutch embassy to sign a paper
2019-09-13T00:55:23 < mawk> it's called the european weapon card
2019-09-13T00:55:29 < Steffanx> but i dont want you to
2019-09-13T00:55:31 < mawk> :(
2019-09-13T00:55:39 < jadew> hold on, what kind of weapon do you have?
2019-09-13T00:55:42 < Thorn> inb4 Breivik 2.0
2019-09-13T00:55:44 < mawk> I have nothing
2019-09-13T00:55:45 < jadew> a gun?
2019-09-13T00:55:48 < jadew> ah
2019-09-13T00:55:48 < mawk> I just have the permit
2019-09-13T00:56:02 < jadew> that should scare a few people away
2019-09-13T00:56:03 < mawk> to have a weapon I must make 3 controlled shoots / year in front of an assessor
2019-09-13T00:56:04 < mawk> and I made 0
2019-09-13T00:56:27 < mawk> but I can get low tech weapons like ancient guns with black powder
2019-09-13T00:56:29 < jadew> interesting
2019-09-13T00:56:32 < mawk> but I don't think anyone is scared of that
2019-09-13T00:56:44 < jadew> they will be if you shoot one of them
2019-09-13T00:56:47 < mawk> lol
2019-09-13T00:56:52 < mawk> you take like 5 minutes to load it
2019-09-13T00:57:05 < Thorn> whom do you have to kill
2019-09-13T00:57:06 < mawk> pack the powder, put the leads, put the stopper, push with a stick
2019-09-13T00:57:13 < jadew> you go with it preloaded, shoot one and then pretend it can shoot more :P
2019-09-13T00:57:22 < mawk> you can't keep it preloaded or they remove your license
2019-09-13T00:57:22 < Thorn> mr englishman why you don't recommend g0 PD stuff, it looks pretty cool on paper, with firmware available https://blog.st.com/usb-c-pd-ecosystem-stm32g0/
2019-09-13T00:57:32 < mawk> there are random checks
2019-09-13T00:57:43 < jadew> can you carry a sword?
2019-09-13T00:57:47 < jadew> or a crossbow
2019-09-13T00:57:48 < mawk> good question
2019-09-13T00:57:53 < mawk> a crossbow yes, the permit works
2019-09-13T00:58:01 < mawk> but it's not a bearer's permit, you need to keep it locked away
2019-09-13T00:58:04 < jadew> that would be kick ass
2019-09-13T00:58:13 < mawk> even security guards can't get bearer permit's here, only cops (and not all cops)
2019-09-13T00:58:25 < mawk> if a cop shoots a single bullet he is automatically suspended until there is an investigation
2019-09-13T00:58:27 < mawk> it's not the US
2019-09-13T00:58:30 < jadew> I don't think you can get that in here either
2019-09-13T00:58:36 < jadew> but then again, we don't have terrorists
2019-09-13T00:59:07 < mawk> well they tightened gun control with terrorism
2019-09-13T00:59:12 < mawk> they don't want people to arm themselves
2019-09-13T00:59:29 < mawk> arm bearing permit was taken away the day before WW2
2019-09-13T00:59:48 < mawk> never brought back again; the stories goes that it's not in our constitution because it was so evident they didn't have to put it in
2019-09-13T00:59:49 < Thorn> so polandball comics were rght
2019-09-13T00:59:58 < jadew> I think communists did that here
2019-09-13T01:01:43 < jadew> the thought of owning a fire arm scares me
2019-09-13T01:03:35 < Cracki> it's a calculation. what's the chance that you need to defend yourself? what's the chance that the police is there in time to do it for you?
2019-09-13T01:04:11 < Cracki> and that's just the everyday case. muricans have the right to weapons because they had to fight against british rule
2019-09-13T01:04:18 < mawk> there's also the risk between not doing anything vs being threatening to the assaulter
2019-09-13T01:04:22 < mawk> the latter may be more risky
2019-09-13T01:04:29 < mawk> especially if he fears for his own life
2019-09-13T01:05:00 < mawk> so you have to shoot first or something, but self-defense laws are very strict
2019-09-13T01:05:06 < mawk> if you answer to a knife with a gun, you go to jail for murder
2019-09-13T01:05:15 < mawk> it must be strictly proportionnate to the assault nature
2019-09-13T01:05:18 < Cracki> yes. "violence for peace" only works by escalating until the opponent is subdued. it's a gamble.
2019-09-13T01:05:38 < jadew> mawk, same here, and I find that stupid
2019-09-13T01:05:44 < Cracki> almost proportional or you can never get the upper hand.
2019-09-13T01:06:08 < Cracki> they don't allow overkill under the excuse of self defense.
2019-09-13T01:06:18 < jadew> that's their problem
2019-09-13T01:06:39 < jadew> if someone breaks into my house, I'll assume the worst
2019-09-13T01:06:44 < mawk> yeah
2019-09-13T01:06:55 < mawk> once in a while some guy that shot a burglar goes to jail, it makes the news
2019-09-13T01:07:00 < mawk> I think non-lethal weapons are the way to go
2019-09-13T01:07:07 < Thorn> that is bullshit, a knife is a deadly weapon, and there're american police videos where a simulated criminal charges the cop while he tries to draw his gun and shoot. turns out you can take up to 10 steps before you will be shot
2019-09-13T01:07:20 < jadew> mawk, no
2019-09-13T01:07:34 < jadew> it's better to go to jail than risk dying at the hand of a low life
2019-09-13T01:07:36 < mawk> if you need to defend yourself and not go to jail you don't have much choices
2019-09-13T01:07:39 < mawk> yeah
2019-09-13T01:07:45 < Cracki> how can we shoehorn an stm32 into this discussion?
2019-09-13T01:07:45 < mawk> it's not because it's non-lethal that it isn't effective
2019-09-13T01:07:48 < mawk> lol
2019-09-13T01:07:52 < mawk> stm32-protected gun
2019-09-13T01:07:55 < mawk> with fingerprint reader
2019-09-13T01:07:57 < mawk> my next project
2019-09-13T01:07:59 < Cracki> stm32cubeAI for friend-foe-detection?
2019-09-13T01:08:18 < Cracki> a tiny piece of silicon decides whether you meet your maker
2019-09-13T01:08:23 < mawk> lol
2019-09-13T01:08:31 < mawk> I saw ads for that thing in my mailbox
2019-09-13T01:08:37 < mawk> it's a ML framework for stm32 ?
2019-09-13T01:08:42 < Cracki> i really should continue my work on the auto-aiming camera
2019-09-13T01:08:43 < mawk> I would have thought that required a GPU
2019-09-13T01:08:47 < Cracki> it is
2019-09-13T01:08:50 < Cracki> nah
2019-09-13T01:08:59 < Cracki> for inference on simple data like audio, it works just fine
2019-09-13T01:09:05 < Cracki> even camera video
2019-09-13T01:09:06 < mawk> but pre-trained
2019-09-13T01:09:08 < jadew> Thorn, I saw that thing too, with the gun vs knife
2019-09-13T01:09:10 < mawk> you don't train on a stm32
2019-09-13T01:09:15 < Cracki> sure, inference is the execution, forward pass
2019-09-13T01:09:25 < mawk> you can use the dsp ?
2019-09-13T01:09:26 < Cracki> nobody trains on intel cpus either, it's all gpu or more specialized
2019-09-13T01:09:29 < mawk> to make the matrix multiplication
2019-09-13T01:09:32 < mawk> or it's all cpu
2019-09-13T01:09:35 < Cracki> yes they use the dsp parts of stm32
2019-09-13T01:09:38 < mawk> nice
2019-09-13T01:09:54 < Cracki> their cubeAI merely takes a network, condenses it down (uint8 or even less instead of floats)
2019-09-13T01:10:06 < Cracki> and schedules it for best performance on the chosen chip family
2019-09-13T01:10:17 < Cracki> with an eye on caches where available etc
2019-09-13T01:10:26 < Steffanx> so mr BrainDamage is happy with his kobo and scientific books?
2019-09-13T01:10:27 < mawk> you're using it ?
2019-09-13T01:10:31 < mawk> kobo
2019-09-13T01:10:40 < mawk> you're all poor people, I have the superior kindle
2019-09-13T01:10:51 < Cracki> it is flammable
2019-09-13T01:10:59 < jadew> how much is that kobo?
2019-09-13T01:11:12 < Cracki> website said 120-280 muribucks
2019-09-13T01:11:35 < jadew> isn't that as much as a kindle?
2019-09-13T01:11:39 < Cracki> their lineup needs a table for comparison. they all have tolerable screen size
2019-09-13T01:11:44 < Steffanx> So change that to euro and add 20%
2019-09-13T01:11:59 < Cracki> I think the advantages mentioned earlier were a more open system
2019-09-13T01:12:15 < mawk> yeah
2019-09-13T01:12:24 < jadew> ah, right
2019-09-13T01:12:27 < mawk> at least if you know a bit about computers you can unlock amazon purchases
2019-09-13T01:12:34 < mawk> get .epub or whatever from the .azw3
2019-09-13T01:12:51 < jadew> is it bigger?
2019-09-13T01:16:05 < Steffanx> depends on if you get a white or a black one.
2019-09-13T01:16:24 < jadew> hah
2019-09-13T01:26:20 < jadew> any good movies recently?
2019-09-13T01:26:27 < jadew> I'm starving for a good movie
2019-09-13T01:27:40 < specing> jadew: the BBC made a movie about brexit
2019-09-13T01:27:52 < jadew> but I already know about brexit
2019-09-13T01:29:40 < jadew> what's the news on that tho?
2019-09-13T01:29:49 < jadew> did they get a deal? are they still leaving?
2019-09-13T01:30:10 < jadew> last time I checked, they were leaving without a deal
2019-09-13T01:31:25 < jadew> it's gonna suck if they leave without a deal
2019-09-13T01:31:37 < jadew> I'll have to charge my UK customers more
2019-09-13T01:32:30 < jadew> I'm actually considering not selling outside of the EU anymore
2019-09-13T01:32:33 < jadew> too much of a hassle
2019-09-13T01:34:34 < Cracki> meow
2019-09-13T01:35:06 < Cracki> if they leave without a deal you can be sure there will be negotiations afterwards
2019-09-13T01:36:24 < Cracki> I still can't believe nobody in romania has made a business out of handling import/export
2019-09-13T01:36:41 < Steffanx> First week/months are going to be fun though
2019-09-13T01:36:58 < Cracki> that's the brains half of any logistics company
2019-09-13T01:37:47 < jadew> Cracki, there are the regular ones... DHL, UPS, etc
2019-09-13T01:37:50 < jadew> but they're too expensive
2019-09-13T01:38:06 < jadew> I had DHL as a shipping option on my website since the very beginning and nobody has opted for that
2019-09-13T01:38:30 < jadew> and why would they? regular post seems to deliver crap in within 1 week anywhere
2019-09-13T01:38:35 < Cracki> yeah fuck those I mean small and medium sized companies
2019-09-13T01:38:37 < jadew> maybe one week and a half to the US
2019-09-13T01:39:12 < Cracki> I'm thinking of companies that actually talk to you rather than be an opaque machine
2019-09-13T01:39:34 < Cracki> like a travel agency, you see?
2019-09-13T01:39:35 < jadew> it's not a bad idea
2019-09-13T01:39:56 < Cracki> you can book your own flight and your own hotel AND takec are of all the visa bs
2019-09-13T01:39:58 < jadew> I'm sure there would be customers
2019-09-13T01:40:13 < Cracki> but there are agencies that deal in it all day long and they can cut through the bs
2019-09-13T01:40:32 < jadew> but I think it would end up costing the same as DHL
2019-09-13T01:40:37 < Cracki> not that you'd be/become such a company but if you find such a company, or can encourage someone to do this...
2019-09-13T01:40:45 < Cracki> maybe but DHL is headache

2019-09-13T01:41:11 < Cracki> I don't just mean the actual shipping
2019-09-13T01:41:43 < Cracki> iirc you had headaches with customs too. a logistics company handles that too
2019-09-13T01:42:31 < Cracki> it adds cost because of the service, like a realtor adds cost to simply talking to the owner and renting something
2019-09-13T01:43:00 < jadew> yeah
2019-09-13T01:43:11 < Cracki> you outsource your taxes to a tax dude too, right?
2019-09-13T01:44:20 < jadew> yeah
2019-09-13T01:44:37 < Cracki> cold hard calculation. your time vs their price.

2019-09-13T01:46:51 < jadew> yeah, I'll have to look into it
2019-09-13T01:46:56 < Cracki> that's adjacent to those "trade associations" (guilds/chambers of commerce) I blabbered about
2019-09-13T01:47:27 < jadew> I wouldn't mind having someone else deal with the entire shipping process
2019-09-13T01:50:01 < Cracki> I'd drop that market opportunity on some local startup hub. lots of eager young people waiting for a business idea they can find customers for
2019-09-13T01:51:03 < Cracki> one of the problems startups have is that a founder had an idea but there was no market for that... but in the process of shaking trees, they listened to real people having real aches, and "pivoted" towards solving those problems instead

2019-09-13T02:00:53 < Cracki> boss's customer's customer had some PLC and robotic arms in a logistics hangar. all the gear had traffic lights to indicate stuff
2019-09-13T02:01:16 < Laurenceb_> but y they no raspberry pi 4

2019-09-13T02:02:09 < Laurenceb_> hopefully Qt supports rpi bluetooth
2019-09-13T02:02:09 < jadew> neat, kicad has a footprint generator
2019-09-13T02:02:27 < Laurenceb_> Qt bluetooth support actually seems very nice, makes bluetooth work on lunix in fact
2019-09-13T02:02:29 < Cracki> mesmerizing https://www.youtube.com/watch?v=bFaN9_n_7Uw
2019-09-13T02:03:21 < BrainDamage> rpi 3 bluetooth is a special kind of shit in that you need to patch bluez to load firmware
2019-09-13T02:03:27 < BrainDamage> as supposed to the kernel doing it
2019-09-13T02:03:47 < BrainDamage> however, the interface that bluez provides is universal for all the devices
2019-09-13T02:03:59 < Cracki> https://www.directindustry.de/prod/auer-signal/product-14189-1346787.html
2019-09-13T02:04:28 < Cracki> thanks. I had hoped to get my rpi3 to do some bluetooth eventually...
2019-09-13T02:04:57 < specing> broadcomm again getting away with everything
2019-09-13T02:05:07 < Laurenceb_> BrainDamage: so does the Raspberry pi kernel build work ok?
2019-09-13T02:05:41 < BrainDamage> 'yes', it has some idiocies
2019-09-13T02:05:49 < BrainDamage> like no preemption enabled
2019-09-13T02:05:53 < Laurenceb_> ok maybe it will work...
2019-09-13T02:06:13 < Laurenceb_> this whole system is probably going to kill the wambulance alternator
2019-09-13T02:06:19 < Laurenceb_> about 100W total power
2019-09-13T02:07:03 < BrainDamage> I doubt so, if a car stereo can draw more than that ...

2019-09-13T10:19:31 < dongs> $28k for chinese pogopins that sell for $1.50/100pcs and some flexible arms from china
2019-09-13T10:19:54 < dongs> doesnt even look very practical, what if you need to probe more than 4 things
2019-09-13T10:20:11 < dongs> fucking make:r faggots
2019-09-13T10:22:56 < dongs> fuck off nigger
2019-09-13T10:23:11 < dongs> yeah maybe you dont if your probing equipment is that fucking chink saleae clone
2019-09-13T10:23:23 < dongs> but even that shit has 8 channels of garbage
2019-09-13T10:23:43 < veverak> lol
2019-09-13T10:23:46 < veverak> :D
2019-09-13T10:37:32 < Steffanx> But you are a pro right? You work in the business.
2019-09-13T10:55:47 < ThatDamnRanga> LOL Yeah I can't see that being accurate enough
2019-09-13T10:57:06 < day> it's kickstarter people. the only thing it kickstarts is someones bankaccount

2019-09-13T11:07:14 < jadew> ThatDamnRanga, why do you think it's so pixelated?
2019-09-13T11:07:33 < ThatDamnRanga> Yup
2019-09-13T11:08:01 < ThatDamnRanga> Even with a 3D printed jig + pogos I still have some challenges managing the required accuracy to hit a debug connector
2019-09-13T11:11:53 < ThatDamnRanga> Can't imagine aliexpress flexi-arms hitting the contacts on a QFN chip with any kinda accuracy or longevity
2019-09-13T11:12:34 < ThatDamnRanga> (Am I the only one who will always go with the QFP package over QFN still?)
2019-09-13T11:12:41 < dongs> no
2019-09-13T11:12:52 < dongs> if I need to probe shit I will leave testpoints where needed
2019-09-13T11:14:44 < ThatDamnRanga> that's not the reason for my decision tbh. It's the ease of visually checking the quality of the contact with the board, and positioning etc
2019-09-13T11:14:50 < ThatDamnRanga> I don't have an OpenPNP like you :P
2019-09-13T11:16:15 < jadew> yeah, I have the same issue with QFNs, but somehow I ended up with more than I wanted on this board I'm working on
2019-09-13T11:16:20 < jadew> and a couple of 0402
2019-09-13T11:17:15 < jadew> aligning them is just difficult
2019-09-13T11:17:27 < jadew> maybe I should get one of those manual pnp machines
2019-09-13T11:18:01 < ThatDamnRanga> I'm gonna have a bit of room to play with on mine, given the connector on the board is a TE SuperSeal. And it'll have two daughterboard connectors that won't be small :P
2019-09-13T11:18:15 < ThatDamnRanga> so the 15 or so components on the main board can be as big as they want within reason
2019-09-13T11:19:25 < jadew> I needed a couple of more mm to fit more stuff under a shield and had to switch to 0402 and UQFN
2019-09-13T11:23:13 < qyx> qfns are great
2019-09-13T11:23:17 < qyx> no solder bridges
2019-09-13T11:23:37 < jadew> if you managed to align them
2019-09-13T11:23:51 < qyx> they align themselves
2019-09-13T11:24:07 < qyx> wat
2019-09-13T11:26:40 < ThatDamnRanga> I think you're assuming we all have surgeon hands :P

2019-09-13T12:32:48 < jadew> qfp is easy
2019-09-13T12:33:21 < jadew> you heat everything up
2019-09-13T12:34:17 < jadew> you don't need an oven
2019-09-13T12:34:20 < jadew> just hot air
2019-09-13T12:34:30 < jadew> you don't even need paste
2019-09-13T12:34:36 < jadew> you just put a bit of solder on the pad
2019-09-13T12:34:45 < jadew> then you heat it up and put the IC
2019-09-13T12:34:57 < jadew> you put a larger nozzle
2019-09-13T12:35:30 < jadew> 5mm dia?
2019-09-13T12:36:49 < jadew> the tiny nozzle for my station can easily blow away 0603 components, even on the lowest air speed setting
2019-09-13T12:37:35 < jadew> yeah, you only use that for rework
2019-09-13T12:37:51 < jadew> taking things apart while holding them with tweezers
2019-09-13T12:38:21 < jadew> it's good for concentrated heat, but when assembling something you don't need that, especially for ICs
2019-09-13T12:38:45 < jadew> I think the nozzle I use for ICs is 7-8mm
2019-09-13T12:39:21 < jadew> what do you use instead?
2019-09-13T12:44:46 < srk> I've hacked a small syringe to desoldering gun pump for placing MCUs - drill a hole into side of the syringe which so you can plug it with a finger. used the tip and cups from crappy vacuum pen
2019-09-13T12:46:02 < jadew> srk, I'm using the same setup, but with a different tip
2019-09-13T12:46:06 < ThatDamnRanga> Honestly if I go the DIY route, my hands are so imprecise at small movements I'll have to rig something using my VR kit and steppers
2019-09-13T12:47:08 < ThatDamnRanga> I can, and have, soldered DDR and NAND chips by hand. It took too bloody long
2019-09-13T12:47:30 < srk> if you place your hands on the table and practice a bit it's doable :)
2019-09-13T12:47:50 < ThatDamnRanga> srk, I failed handwriting lessons due to fine motor issues
2019-09-13T12:48:19 < ThatDamnRanga> Ironically, give me a steering wheel and I ain't half bad, but those movements are quite a bit larger
2019-09-13T12:48:51 < srk> ah, ok :)
2019-09-13T12:49:18 < srk> there are some ppl using manual pick'n'place machines to aid with positiong
2019-09-13T12:49:25 < ThatDamnRanga> I /can/ hand solder 0603, I've done it more than once, but 5+ minutes per component is a lot of coin lost
2019-09-13T12:49:57 < ThatDamnRanga> I can see manual P&P approaches, especially if we're talking a machine with crank handles and 0.05mm positional accuracy, working fine for me
2019-09-13T12:50:05 < srk> we use diy reflow oven for SMD and just rework bugs when needed
2019-09-13T12:50:06 < ThatDamnRanga> but at that point, I have enough left over 3d printer parts...
2019-09-13T12:50:56 < srk> and then you spend ages fighting with openPNP :D
2019-09-13T12:51:11 < ThatDamnRanga> eh, once you get it right I'm sure it's all G
2019-09-13T12:51:29 < srk> just to be disappointed with the precision of the steppers :D
2019-09-13T12:51:47 < ThatDamnRanga> Eh, how well steppers perform is down to the accuracy of the things they'r attached to
2019-09-13T12:51:50 < srk> which is not that good, especially with cheapo microstepping drivers
2019-09-13T12:51:55 < ThatDamnRanga> with something like that I'd want ballscrews on both X and Y
2019-09-13T12:52:10 < srk> yeah, then it would be too slow :D
2019-09-13T12:52:21 < ThatDamnRanga> ... I don't think so
2019-09-13T12:52:38 < ThatDamnRanga> my printer can move the entire travel of its Z axis in 1.5 seconds... 
2019-09-13T12:52:49 < ThatDamnRanga> it just doesn't ordinarily do so
2019-09-13T12:53:04 < srk> steppers are not good for driving lead/ball screws
2019-09-13T12:53:09 < srk> that's still way too slow for pnp :)
2019-09-13T12:53:26 < srk> and probably pushing your steppers to the limit
2019-09-13T12:53:32 < ThatDamnRanga> Most belt driven OpenPNP systems I've seen place one component every 5+ seconds

2019-09-13T13:15:36 < jadew> man... I hate sourcing cables from china
2019-09-13T13:15:54 < jadew> they have different centimeters
2019-09-13T13:16:37 < jadew> chinese centimeters are are 10 to 20% shorter than regular centimeters
2019-09-13T13:17:17 < ThatDamnRanga> Makes up for australian centimeters
2019-09-13T13:17:23 < ThatDamnRanga> they seem to be 40% longfer
2019-09-13T13:20:58 < ThatDamnRanga> What I love is ordering '2M' cables from local suppliers
2019-09-13T13:21:04 < ThatDamnRanga> they arrive and theyre 6ft cables
2019-09-13T13:21:14 < ThatDamnRanga> like fuck there's 20 centimetres there you dumb cunts
2019-09-13T13:36:24 < jadew> what's even more annoying is that it was an expensive cable assembly (for chinese standards)
2019-09-13T13:36:42 < grummund> Anyone know how you flash a device from inside eclipse gnu mcu?
2019-09-13T13:36:52 < grummund> ... as opposed to debug/run with the programmer attached, which works.
2019-09-13T13:37:40 < kakimir> yes
2019-09-13T13:38:00 < grummund> ok, gimme a clue please. ;)
2019-09-13T13:38:18 < kakimir> I recall you need to manually write load to gdb terminal in the program
2019-09-13T13:38:40 < kakimir> but when I did it - it wanted the path of the .elf
2019-09-13T13:38:47 < kakimir> and then I just gave up
2019-09-13T13:39:28 < grummund> meh

2019-09-13T13:42:31 < kakimir> yes
2019-09-13T13:43:08 < englishman> ThatDamnRanga: one part every 5 seconds sounds pretty good for openpnp.
2019-09-13T13:43:15 < grummund> why doesn't the code just continue to run when the debugger is detached?
2019-09-13T13:43:24 < englishman> it is a make-work project anyway, the goal is not to have a useful machine.
2019-09-13T13:44:59 < englishman> the goal is to make something because you have too much free time and don't know what you want.
2019-09-13T13:45:00 < kakimir> grummund: did you try to turn it off and on?
2019-09-13T13:45:00 < kakimir> what chip?
2019-09-13T13:45:12 < grummund> stm32f030 and yes unplugged it all then re-applied power.
2019-09-13T13:45:37 < grummund> there is a BOOT jumper but i tried it in both positions
2019-09-13T13:46:12 < kakimir> is your reset pin conditioned with external circuit as required per datasheet?
2019-09-13T13:46:47  * grummund presumes so
2019-09-13T13:46:56 < Thorn> https://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/mcu-mpu-eval-tools/stm32-mcu-mpu-eval-tools/stm32-discovery-kits/b-g431b-esc1.html
2019-09-13T13:47:05 < kakimir> also there is some debugging setting that only allows mcu to excecute when debugging
2019-09-13T13:48:10 < kakimir> I don't know the exact mechanics of that
2019-09-13T13:48:38 < ThatDamnRanga> not on the M4/M0 products as best I can tell
2019-09-13T13:48:42 < ThatDamnRanga> they won't run from RAM
2019-09-13T13:48:49 < grummund> is it because the code is using trace functions, and that has nowhere to go with the debugger deteched?
2019-09-13T13:50:07 < grummund> yes that's it
2019-09-13T13:50:21 < kakimir> oh
2019-09-13T13:50:52 < grummund> that's kinda unexpected
2019-09-13T13:53:56 < Steffanx> Semihosting?
2019-09-13T13:55:14  * grummund hasn't figured out what that means yet, but yes.
2019-09-13T13:55:26 < Steffanx> You can always add a check if a debugger is attached and not call your trace stuff when it's not connected
2019-09-13T13:55:45 < Steffanx> There is a bit for that in some register I dont remember the name of 
2019-09-13T13:55:52 < Steffanx> DBGsomething
2019-09-13T13:57:14 < Steffanx> But perhaps F0 (cortex m0) doesnt have it
2019-09-13T13:58:02 < grummund> maybe i'll try the same on F103 and see what happens
2019-09-13T14:01:06 < Steffanx> Semihosting works
2019-09-13T14:01:45 < Steffanx> By adding a break point which your debugger  detects and then reads some memory
2019-09-13T14:01:59 < Steffanx> You still hit the break point without debugger
2019-09-13T14:06:04 < grummund> when creating the project it has options
2019-09-13T14:06:34 < Steffanx> ohno, Haohmaru is a smoker?
2019-09-13T14:06:42 < Steffanx> or a vaper
2019-09-13T14:09:37 < grummund> Use system calls: Freestanding (no POSIX system calls) / POSIX (system calls implemented by application code) / Semihosting (POSIX system calls via host)
2019-09-13T14:09:55 < grummund> Trace output: None (no trace output) / ARM ITM (via SWO) / Semihosting STDOUT stream / Semihosting DEBUG channel
2019-09-13T14:14:13 < Thorn> why power control / overcurrent pins on hubs? so that you can query & control them via usb hub class requests?

2019-09-13T17:51:00 < dongs> so im trying to do TPS63001 in a system with a power switch and permanently tied battery
2019-09-13T17:51:18 < dongs> it seems VINA is drawing non-trivial amount of current even when the system is off (EN pin low)
2019-09-13T17:51:38 < dongs> i wonder if I should connect VINA w/EN for this
2019-09-13T17:52:02 < dongs> there's a hbridge or wahtever for the coil part so VIN is definitely not leaking through the inductor
2019-09-13T17:52:11 < dongs> but VINA is powering some control circuits or wahtever according to diagram
2019-09-13T17:54:05 < dongs> power switch just dicks EN of TPS (and a few otehr chips) between GND and VBAT
2019-09-13T17:58:07 < Thorn> tps6300x is the kind of chip than FAEs will run away from

2019-09-13T20:46:31 < Cracki> he has a couple more :P
2019-09-13T20:46:44 < Cracki> nothing of that caliber (of tree) tho
2019-09-13T20:48:15 < Cracki> only one of his videos I didn't see a point in was where he used a skid steer attachment to screen dirt with 1-inch and 3-inch screens... when there are purpose-built machines for that job
2019-09-13T20:53:29 < grummund> afaict in eclipse 'Run' mode is basically Debug mode without breakpoints, taht is the debugger stays attached until you tell it to stop.
2019-09-13T20:57:04 < Cracki> with a lot more than no breakpoints
2019-09-13T20:57:08 < Cracki> it runs the program.
2019-09-13T20:57:43 < Cracki> the ability to kill the program shouldn't be enough to call it debugging without breakpoints
2019-09-13T20:59:05 < grummund> i suppose it makes sense to stay connected and collect any trace output
2019-09-13T20:59:47 < Cracki> that happens outside of debugging too?
2019-09-13T21:00:00 < grummund> yes
2019-09-13T21:00:06 < Cracki> collecting stdout is a common feature. not considered "trace"
2019-09-13T21:00:35 < Cracki> wait, you're talking about stm32 yes? serial wire output?
2019-09-13T21:01:05 < grummund> there is Debug and Release builds, and then there is Debug and Run modes.
2019-09-13T21:01:26 < grummund> the word Debug used in different contexts
2019-09-13T21:02:00 < Cracki> last I checked (last truestudio) there was only debugging because they didn't bother implementing run mode. you had to set up a "tool command" to do that.
2019-09-13T21:02:06 < Cracki> nobody talks about build types
2019-09-13T21:02:20 < grummund> yeah this is eclipse
2019-09-13T21:02:39 < grummund> "state-of-the-art" it says on the tin.
2019-09-13T21:02:44 < Cracki> so they finally managed to make "run" do something on stm32?
2019-09-13T21:03:30 < grummund> yeah it launches a debug session without breakpoints :p
2019-09-13T21:03:58 < Cracki> that's something at least. I always edit the debugger script to remove the "tbreak main" or whatever it is they do
2019-09-13T21:04:26 < Cracki> eclipse switching perspectives also annoys me because it takes a second
2019-09-13T21:04:54 < Cracki> have they figured out how to keep serial wire viewer logging enabled between debug sessions? it's total bullshit that I have to enable that every time
2019-09-13T21:05:18 < grummund> oh yes that's the other interesting thing... if you remove the breakpoint at main then (assuming no other breakpoints hit) it's impossible to pause!
2019-09-13T21:05:34 < Cracki> nonsense, debug perspective, pause, works
2019-09-13T21:05:52 < grummund> with a breakpoint at main it does yes
2019-09-13T21:06:12 < Cracki> I can't believe it

2019-09-13T21:13:44 < grummund> so basically you click Run, it launches GDB, which flashes and resets the MCU and then sits there capturing trace output.
2019-09-13T21:16:06 < grummund> you edit the code, click Run, it re-builds successfully and then tries to connect tp GDB and fails because the previous session is still running.

2019-09-14T02:55:05 < Mangy_Dog> WELL HUMANS ARE TASTY
2019-09-14T02:55:10 < Mangy_Dog> gah caps
2019-09-14T02:55:24 < Mangy_Dog> nn :)
2019-09-14T02:56:12 < Cracki> have you tasted human flesh recently?
2019-09-14T02:56:30 < Mangy_Dog> well it depends how you put it
2019-09-14T02:56:48 < Laurenceb_> is slack a spy project?
2019-09-14T02:56:56 < Laurenceb_> should I give them my email?
2019-09-14T02:57:01 < Cracki> I can believe it. puppies are tortured because it makes them taste sweeter. humans are living under constant terror too, we must taste amazing
2019-09-14T02:57:18 < Cracki> don't trust slack, don't trust discord
2019-09-14T02:57:19 < Mangy_Dog> :o
2019-09-14T02:57:36 < Laurenceb_> kek discord
2019-09-14T02:57:44 < Laurenceb_> I've yet to work out how discord works
2019-09-14T02:57:52 < Laurenceb_> its just weird and autistic
2019-09-14T02:58:03 < Cracki> obv
2019-09-14T02:58:16 < Laurenceb_> also it keeps glitching out on lunix
2019-09-14T02:58:29 < Laurenceb_> and search seems broken
2019-09-14T02:58:33 < Cracki> these "servers" are only good for leaking enemy camp intel
2019-09-14T02:58:45 < Cracki> shit reinvention of irc, tbh
2019-09-14T02:58:59 < Laurenceb_> yeah
2019-09-14T02:59:02 < BrainDamage> use discord from the browser
2019-09-14T02:59:37 < BrainDamage> also, are you chosing slack yourselfor was it imposed from whatever IT admin you have there?
2019-09-14T02:59:40 < Laurenceb_> ok
2019-09-14T02:59:47 < Laurenceb_> nah nasaspaceflight autists use it
2019-09-14T03:00:01 < Laurenceb_> I think they have blown their chances of getting funding tbh
2019-09-14T03:00:19 < Laurenceb_> they are determined to think they are better than the funding agency
2019-09-14T03:00:24 < Cracki> if you use slack, you blow for funding
2019-09-14T03:00:58 < Laurenceb_> >no we dont have to read the grant guidelines, we are better than that
2019-09-14T03:01:01 < BrainDamage> keybase works as a decent slack alternative fwiw, it even has client side encryption and has free cloud storage up to 120GB
2019-09-14T03:01:34 < BrainDamage> there's a bit of crypocurrency bullshit on the side, but you can ignore it
2019-09-14T03:01:45 < BrainDamage> but it's not compatible with slack
2019-09-14T03:01:52 < Laurenceb_> >no we think the guidelines drawn up by the funding agency are stupid, so we will just ignore them

2019-09-14T03:03:01 < aandrew> holy fuck staples.ca is a pile of steaming dogshit
2019-09-14T03:03:05 < Cracki> bridges are everywhere, between anything. slack, telegram, irc, discord, ...
2019-09-14T03:03:11 < Laurenceb_> we have crossed the autism event horizon
2019-09-14T03:03:11 < aandrew> monday: ordered office chair, folding table, chair mat and table "riser". estimated ship date was monday. payment went through, then ship date became 11-20 days. whatever.
2019-09-14T03:03:19 < Cracki> you want a red streamline, aandrew ?
2019-09-14T03:03:28 < Cracki> haha
2019-09-14T03:03:34 < aandrew> tuesday: table and chair arrive (no warning, just happened to be here). called to ask about the other two items and return the table because I discovered I actually did have room for hte longer one
2019-09-14T03:03:44 < aandrew> on the phone they tell me that the chair mat was cancelled because it's no longer available. I ask why I wasn't notified and you could hear them shrug over the phone. Fine,
2019-09-14T03:03:47 < Cracki> they can't find a logistics company that'll drive the stuff to your door
2019-09-14T03:04:00 < aandrew> whatever. I order the longer table and matching riser, and cancel the shorter riser
2019-09-14T03:04:01 < Cracki> they expect you to have office hours
2019-09-14T03:04:37 < aandrew> thursday: I have to leave for one hour in the day and THAT is the hour that they try to deliver. I called beforehand to make sure they'd go next door to sign for it, also tried to schedule the delivery outside that window "just in case" - can't do it they tell me on the phone that there will be 3 attempts made so don't worry, ok, not ideal but whatever
2019-09-14T03:04:49 < aandrew> oh, forgot wednesday
2019-09-14T03:04:57 < aandrew> wednesday: I get an email that my order was cancelled. no explanation. Order the fucking table again since it was just the table that was cancelled, not the riser.
2019-09-14T03:05:09 < aandrew> back to thursday:
2019-09-14T03:05:14 < aandrew> thursday: I have to leave for one hour in the day and THAT is the hour that they try to deliver. I called beforehand to make sure they'd go next door to sign for it, also tried to schedule the delivery outside that window "just in case" - can't do it they tell me on the phone that there will be 3 attempts made so don't worry, ok, not ideal but whatever
2019-09-14T03:05:19 < aandrew> I get an email at 1:15pm saying the delivery attempt was made but couldn't be delivered, so order was cancelled.
2019-09-14T03:05:22 < aandrew> wtf, I'm pissed now. call and discover there was no delivery attempt, that is just internal code for "it wasn't on the truck". I don't buy it, just reissue the fucking order
2019-09-14T03:05:27 < aandrew> today I get another cancellation notice.
2019-09-14T03:05:32 < aandrew> order the thing on amazon, call staples and tell them to take every single order and shove it
2019-09-14T03:05:37 < aandrew> fucking incompetence beyond measure
2019-09-14T03:05:48 < Cracki> amazing
2019-09-14T03:06:01 < aandrew> all of this because I want a cheap fucking table for the apartment to work on
2019-09-14T03:06:15 < aandrew> home depot could deliver but wants 10-20 days to figure out how to do it

2019-09-14T03:44:28 < dongs> yes
2019-09-14T03:44:33 < dongs> thats whyi used it
2019-09-14T03:44:40 < Thorn> thanks, sounds like what I need
2019-09-14T03:44:55 < Thorn> have you also used FE1.1 etc. hubs?
2019-09-14T03:45:11 < dongs> lol yes once, thanks to dealextreme
2019-09-14T03:45:13 < dongs> never again
2019-09-14T03:45:25 < dongs> if you want a cheap hub just use GL851
2019-09-14T03:45:46 < dongs> tsop version is like 40c

2019-09-14T03:45:55 < dongs> err GL850
2019-09-14T03:46:17 < dongs> (cheaper than FE1.1 trash actually looks like
2019-09-14T03:47:07 < Thorn> yeah I wanted per-port power switch / overcurrent pins, ssop doesn't have that iirc
2019-09-14T03:47:32 < Thorn> but if fe1.1 is shit then I don't have much choice
2019-09-14T03:47:47 < dongs> only lqfp48 version of GL does
2019-09-14T03:48:02 < dongs> well, its shit in the sense that its literally only USB2.0 ful-speed
2019-09-14T03:48:25 < dongs> oh, datasheet claims fullspeed
2019-09-14T03:48:33 < dongs> i must haev had the shit that was FS only
2019-09-14T03:48:45 < Thorn> I only need FS anyway for this project
2019-09-14T03:49:53 < dongs> ok i dk try it i guess. personally i'd use GL even if FE was slightly cheaper cuz i know it works at least ;p
2019-09-14T03:50:06 < dongs> time to drive out, good luck

2019-09-14T16:01:10 < qyx> I confirmed it is not a hw problem, both scl and sda have no transitions
2019-09-14T16:01:25 < qyx> but they can go low/high if I configure them as gpio
2019-09-14T16:01:55 < qyx> so I am suspecting some missing register setting somewhere in PWR or what

2019-09-14T16:41:20 < Laurenceb_> I'm confused by this starship shit
2019-09-14T16:41:22 < Laurenceb_> https://forum.nasaspaceflight.com/index.php?topic=48893.20
2019-09-14T16:41:29 < Laurenceb_> >its not going to the stars
2019-09-14T16:41:33 < PaulFertser> And when I was going through ML course on Coursera from prof. Hinton, it was very exciting, fun and challenging, despite being delivered in a relatively dull tone.
2019-09-14T16:41:38 < Laurenceb_> >its being assembled in the open in murica
2019-09-14T16:41:44 < Laurenceb_> how will they fix the bullet holes?
2019-09-14T16:41:56 < Thorn> Dave isn't really teaching anything anymore (afaik, I mostly stopped watching him)
2019-09-14T16:42:05 < PaulFertser> So I do not think "like that" is super important, Thorn.
2019-09-14T16:42:21 < Laurenceb_> >Dave isnt teaching anything
2019-09-14T16:42:30 < Laurenceb_> imagine being this slow
2019-09-14T16:42:41 < Laurenceb_> he has never taught anything
2019-09-14T16:43:05 < Laurenceb_> he is an australian shitposter
2019-09-14T16:43:06 < BrainDamage> it takes him 1h to explain something that a normal human takes 2 minutes
2019-09-14T16:43:10 < Laurenceb_> yeah
2019-09-14T16:43:18 < Laurenceb_> >normal human
2019-09-14T16:43:29 < Laurenceb_> a new phrase for non australians
2019-09-14T16:43:38 < Thorn> he did have some whiteboard videos and stuff, in addition to lab videos (how not to blow up your scope etc.)
2019-09-14T16:43:45 < Laurenceb_> >insert ED page on australian breeding here
2019-09-14T16:45:09 < Laurenceb_>  "the Australian is formed through selective cross breeding of Aborigines with Irish serial killers"
2019-09-14T16:50:30 < Laurenceb_> oh wow printouts of that page were discussed in the Australian parliament debate on webshite blocking

2019-09-14T16:52:57 < dongs> sup pros
2019-09-14T16:53:54 < antto> anyone know what's this blue circle thing? https://talkford.com/community/uploads/monthly_09_2011/post-60118-0-17204300-1315310590.jpg
2019-09-14T16:54:27 < Laurenceb_> >ford
2019-09-14T16:54:28 < dongs> obviously antenna of some kind?
2019-09-14T16:54:29 < Laurenceb_> uh oh
2019-09-14T16:54:37 < antto> it is part of something that needs to sense the rotation (actually the position of something that rotates)
2019-09-14T16:54:39 < Laurenceb_> I need to fix my ford laters
2019-09-14T16:54:57 < antto> but i wonder how it works
2019-09-14T16:55:07 < Laurenceb_> nice thats one sweet antenna
2019-09-14T16:55:34 < Laurenceb_> looks like circularly polarised patch type thing
2019-09-14T16:55:38 < Laurenceb_> v interesting design
2019-09-14T16:55:45 < Laurenceb_> what is this thing?
2019-09-14T16:55:57 < antto> the other part of this is sorta like this: https://allcarsystem.it/_files/200000711-e2034e3fba/g149-electronic-turbocharger-actuator-turbo-actuator-electric-g149-hella-g-149-actuators-[2]-2304-p.jpg
2019-09-14T16:56:22 < Laurenceb_> oh wtf
2019-09-14T16:56:31 < antto> it's from something that has to do with controling something for a turbo thing in a car
2019-09-14T16:56:39 < Laurenceb_> thats some v pro design
2019-09-14T16:56:54 < Laurenceb_> aha
2019-09-14T16:57:06 < antto> the blue/green circles are supposedly sensoring the position of the thing that rotates
2019-09-14T16:57:10 < Laurenceb_> its capacitively or inductivly coupled
2019-09-14T16:57:11 < BrainDamage> it's a position sensor
2019-09-14T16:57:24 < Laurenceb_> yeah
2019-09-14T16:57:28 < BrainDamage> it's still an antenna, just a nfc one
2019-09-14T16:57:31 < Laurenceb_> yeah
2019-09-14T16:57:43 < BrainDamage> still super pro
2019-09-14T16:57:44 < antto> so it's definately not a potentiometer then ;P~
2019-09-14T16:57:49 < Laurenceb_> is that an stm32?
2019-09-14T16:57:58 < Laurenceb_> antto: it has the same function
2019-09-14T16:58:01 < antto> it's some fancy ST chip
2019-09-14T16:58:05 < Laurenceb_> ah ok
2019-09-14T16:58:10 < Laurenceb_> part number?
2019-09-14T16:58:31 < antto> Laurenceb_,  my point is, do the blue/green circles touch?
2019-09-14T16:58:33 < Laurenceb_> I cant quite see it on the photo
2019-09-14T16:58:36 < Laurenceb_> antoo: no
2019-09-14T16:58:46 < dongs> no they dont need to touch
2019-09-14T16:58:50 < Laurenceb_> prob 1mm or so separation
2019-09-14T16:58:51 < antto> if it's a pot, something would be touching a resistive surface
2019-09-14T16:59:00 < Laurenceb_> no its inductive/capacitive
2019-09-14T16:59:03 < dongs> one of them generates a field and the 2nd one receives it
2019-09-14T16:59:08 < Laurenceb_> prob some mixture of the two effects
2019-09-14T16:59:12 < antto> kewl
2019-09-14T16:59:18 < dongs> and knows rotational position of the other one after doing some calculations
2019-09-14T16:59:30 < Laurenceb_> dunno why they didnt just use a magnet
2019-09-14T16:59:32 < dongs> donno which one generates, i think the green one
2019-09-14T16:59:38 < Laurenceb_> seems overengineered
2019-09-14T16:59:40 < dongs> and blue receives
2019-09-14T16:59:50 < BrainDamage> the blue both generates and receives
2019-09-14T16:59:50 < dongs> Laurenceb_: maybe they wanted a really advanced slipring
2019-09-14T17:00:04 < dongs> what if thre's data going across that
2019-09-14T17:00:04 < BrainDamage> the green just distorts the field
2019-09-14T17:00:07 < dongs> plus position
2019-09-14T17:00:15 < Laurenceb_> yeah green looks like its just passive
2019-09-14T17:00:19 < dongs> and/or control signals
2019-09-14T17:01:36 < BrainDamage> magnetic has some issues with the motor that close
2019-09-14T17:01:44 < BrainDamage> rather, why not optical
2019-09-14T17:01:53 < antto> yeah this thing is located near the engine
2019-09-14T17:02:09 < antto> well.. in a car, most of the interesting things are stuffed under the hood, ya know
2019-09-14T17:03:57 < Laurenceb_> BrainDamage: yeah but mag fields go with 1/r^3
2019-09-14T17:04:26 < BrainDamage> I mean the motor on the left of the pic
2019-09-14T17:04:28 < Laurenceb_> I was looking at raw data from that stepper/servo convertor thing on kickstarter 
2019-09-14T17:04:42 < Laurenceb_> managed very high prevision despite being close to a motor
2019-09-14T17:04:52 < Laurenceb_> *precision
2019-09-14T17:04:58 < antto> so if the malfunctions, it's not easy to figure out what's wrong and fix it then
2019-09-14T17:05:11 < antto> they've thought it's a pot and sprayed it with contact spray

2019-09-14T17:06:59 < Laurenceb_> sounds like a bad idea

2019-09-14T20:41:46 < Steffanx> how is the day
2019-09-14T20:42:36 < kakimir> good
2019-09-14T20:43:02 < PaulFertser> Biking?
2019-09-14T20:43:07 < kakimir> yes
2019-09-14T20:43:37 < kakimir> to city
2019-09-14T20:43:42 < PaulFertser> How are you not scared to ride? There's more than 10 accidents with motor bike each fucking day in Moscow...
2019-09-14T20:44:03 < kakimir> it's not moscow here
2019-09-14T20:44:19 < kakimir> you mean leathal accidents?
2019-09-14T20:44:32 < PaulFertser> Not lethal, those are once a week probably.
2019-09-14T20:44:41 < Steffanx> i always imagine the russian roads to be like they are in the videos all over the web PaulFertser.
2019-09-14T20:44:45 < Steffanx> So 10 isnt a surprise
2019-09-14T20:44:55 < kakimir> russian ghost rider is a legend
2019-09-14T20:45:04 < kakimir> I wonder if he still rides
2019-09-14T20:45:14 < kakimir> that moscow morning hours video
2019-09-14T20:45:42 < PaulFertser> Steffanx: I've been to Israel, it looked similar there. Also I guess Italy might be close, but I didn't see it myself.
2019-09-14T20:46:05 < PaulFertser> Russian ghost rider? I've never heard about him/her.
2019-09-14T20:46:25 < Steffanx> you dont believe in ghosts :P
2019-09-14T20:46:47 < kakimir> https://www.youtube.com/watch?v=tgiAXlS8J3k educate yourself PaulFertser
2019-09-14T20:47:36 < Steffanx> im always sorry for the people that have to scrape the body parts of the road when i see vids like that
2019-09-14T20:48:44 < kakimir> I bet many people have died as indirect result of seeing that video
2019-09-14T20:48:50 < kakimir> many
2019-09-14T20:49:38 < PaulFertser> Opening titles from that video: "Two minutes from a motor biker's life are sometimes more interesting than the whole life of many people."
2019-09-14T20:50:39 < kakimir> PaulFertser: when does putin ban youtubes?
2019-09-14T20:51:11 < PaulFertser> kakimir: it's unlikely to happen in my opinion because too many people would get upset, there's no practical reason to do that.

2019-09-14T21:14:46 < qyx> goign to disable LCD to see if it is the case
2019-09-14T21:15:34 < PaulFertser> kakimir: there was a kid 17 y.o. riding a gsx-1000 and in a similar high-speed filtering situation he got hit and damaged his left arm so only the fingers remained functional. There were later videos from him where he uses his right arm to put his left on the handlebar, grabs the grip and continues with power wheelies and other stupid shit on public roads. Some people just never learn. 
2019-09-14T21:17:04 < qyx> it works.

2019-09-14T21:18:01 < qyx> ok so now the only possibility is to bitbang the i2c or disable LCD when reading the sensors
2019-09-14T21:18:25 < kakimir> PaulFertser: I bet adrenaline played a part
2019-09-14T21:18:35 < kakimir> no pain just keep going
2019-09-14T21:18:39 < PaulFertser> kakimir: also, parents' stupidity
2019-09-14T21:20:29 < kakimir> so his parents gave him that bike to test or to have it generally to drive around?
2019-09-14T21:23:49 < PaulFertser> To ride around. And then when he broke it bought another.
2019-09-14T21:24:09 < PaulFertser> broke as in crashed
2019-09-14T21:24:29 < kakimir> on public roads?
2019-09-14T21:27:17 < kakimir> maybe they had too many children
2019-09-14T21:27:37 < kakimir> let them sort it out themselfs and see if they come through
2019-09-14T21:30:13 < PaulFertser> Yes, of course on public roads. I am not sure but probably he was 15 when he got into an accident on public roads on a 1l sports bike, in February (constantly negative temperatures).
2019-09-14T21:31:07 < PaulFertser> That didn't demotivate him at all and so he carried on till he got into the filtering accident.
2019-09-14T21:31:13 < PaulFertser> No idea what he's doing now.

2019-09-15T04:28:00 < Laurenceb_> aham
2019-09-15T04:28:07 < Laurenceb_> allow me to interject for a moment
2019-09-15T04:28:10 < Laurenceb_> Pedophilia (alternatively spelt paedophilia) is a psychiatric disorder in which an adult or older adolescent experiences a primary or exclusive sexual attraction to prepubescent children.[1][2] Although girls typically begin the process of puberty at age 10 or 11, and boys at age 11 or 12,[3] criteria for pedophilia extend the cut-off point for prepubescence to age 13.[4]
2019-09-15T04:28:12 < Cracki> ah, some "alumni" wants attention and started a shitstorm

2019-09-15T04:46:04 < Cracki> kakimir, you heard yourself?
2019-09-15T04:46:30 < Cracki> if a finn pisses in the woods, does it sterilize the soil?
2019-09-15T04:48:09 < kakimir> moose warning it's calves of danger
2019-09-15T04:49:48 < Cracki> aren't they used to you yet?
2019-09-15T04:51:00 < kakimir> obiviously
2019-09-15T04:51:13 < kakimir> they are comming closer
2019-09-15T04:51:32 < Cracki> they don't fear the piss

2019-09-15T05:00:30 < kakimir> it was fun once I took shortcut through a bush and hear moose sound loud and clear inside the bush
2019-09-15T05:00:49 < Cracki> tyvm for the usb article
2019-09-15T05:00:57 < kakimir> first time I heard the sound and didn't quite know what animal it is

2019-09-15T09:23:42 < emeb_mac> Looks like the flash support was added a few weeks back
2019-09-15T09:23:58 < emeb_mac> but in a dev branch on the zylin git

2019-09-15T09:24:14 < emeb_mac> and I'm not good enough w/ git to know how to grab that version
2019-09-15T09:24:45 < emeb_mac> http://openocd.zylin.com/gitweb?p=openocd.git;a=commitdiff;h=434cf2f8a25a8d082f4c955c21761dcd45570516
2019-09-15T09:26:25 < learningc> I want to do the following. A small application than has few buttons. If I press button 1, it will run another firmware from the flash. Button 2 will also run another application.  The purpose is to have multiple independent functionality for the same board.
2019-09-15T09:31:55 < learningc> Some of the issues I will face are: how to jump to another application on the flash. how to write an application to a random location on the flash. 
2019-09-15T09:35:10 < jpa-> learningc: e.g. dso quad does that, but its code is a bit of assembler mess so probably not very helpful
2019-09-15T09:35:30 < jpa-> basically for compiling & flashing to different places, you just need to edit the start address and length in linker script
2019-09-15T09:36:08 < jpa-> and to jump to application, just do the standard bootloader thing with function pointer: https://github.com/PetteriAimonen/ebike-controller/blob/master/src/bootloader.c#L204
2019-09-15T09:36:20 < jpa-> (or with assembler as i've apparently done there)
2019-09-15T09:41:17 < emeb_mac> jpa-: lol, yes.
2019-09-15T09:41:33 < emeb_mac> got an STM32G431 Nucleo board today.
2019-09-15T09:41:57 < emeb_mac> Has ST-Link V3 on it - uses an F722 instead of F103.
2019-09-15T09:43:05 < emeb_mac> I find it enormously amusing that they've got an F7 part as std equip on these $15 Nucleo boards.
2019-09-15T09:43:22 < emeb_mac> more power than most of the targets on those boards.
2019-09-15T09:43:54 < jpa-> back in 2010 it seemed like a great deal that we got two F1's on a $10 discovery
2019-09-15T09:47:00 < rajkosto> FREE SHIT
2019-09-15T09:47:08 < rajkosto> time to get those new nucleos then
2019-09-15T09:47:10 < rajkosto> just for the V3
2019-09-15T09:47:23 < PaulFertser> emeb_mac: that zylin server is just a code review, it's master branch is identical to all the other official git sources. But to get that additional patch you need to do: git fetch http://openocd.zylin.com/openocd refs/changes/07/4807/3 && git checkout FETCH_HEAD
2019-09-15T09:51:05 < PaulFertser> s/it's/its/
2019-09-15T09:52:13 < emeb_mac> PaulFertser: Thanks! Building now...
2019-09-15T09:52:37 < PaulFertser> emeb_mac: welcome :)
2019-09-15T09:53:18 < emeb_mac> rajkosto: and fwiw - digikey/mouser now have the stlinkv3 mini in stock
2019-09-15T09:53:44 < emeb_mac> same F7-based stlink on a teeny-tiny board w/ header
2019-09-15T09:59:05 < emeb_mac> PaulFertser: OK - that seemed to build OK but programming failed. Will try to chase that down later. 
2019-09-15T09:59:13 < emeb_mac> zzzz time now.
2019-09-15T09:59:20 < PaulFertser> emeb_mac: good night
2019-09-15T10:00:23 < emeb_mac> PaulFertser: thanks for your help.
2019-09-15T10:04:17 < learningc> jpa-, For flashing, I just need to change the start address in the linker only? Or do I need to tell my programmer to put the application at a specific address in the flash too?

2019-09-15T13:18:26 < benishor> hi guys, is there such a thing as non volatile memory in stm32f7? I'd like to save user configurations somewhere

2019-09-15T13:28:51 < qyx> benishor: search for backup sram, backup domain registers, eeprom or emulate eeprom in the flash
2019-09-15T13:29:04 < qyx> it depends on the exact mcu what memory it has
2019-09-15T13:30:34 < benishor> 10x qyx, I'm using a stm32f746 discovery board, so it's stm32f746ng
2019-09-15T13:31:57 < qyx> so if you open the datahseet it says 4KB of backup SRAM for example
2019-09-15T13:32:11 < qyx> which looks like the easyest alternative, if you have Vbat supply available
2019-09-15T13:35:11 < benishor> nah
2019-09-15T13:35:23 < benishor> I guess flash will be the better alternative
2019-09-15T13:40:33 < specing> 4K of backup?!?!
2019-09-15T13:40:35 < specing> wow
2019-09-15T13:40:53 < specing> and here I am with 20 bytes on m0
2019-09-15T13:50:31 < Steffanx> Ada is very memory efficient. You only need 20 bytes at most.
2019-09-15T13:51:43 < jpa-> rust is even more memory efficient, it has 0 runtime memory requirement
2019-09-15T13:51:58 < jpa-> (because it tells me my code is crap before i even get a chance to run it)
2019-09-15T13:53:28 < kakimir> how about C?
2019-09-15T13:54:08 < kakimir> it's a legit question
2019-09-15T13:54:24 < jpa-> there are no legit answers here
2019-09-15T13:55:35 < learningc> benishor, how much memory you need?
2019-09-15T13:56:15 < learningc> jpa-, do you use rust on stm32?
2019-09-15T13:56:56 < jpa-> no, but i know people that do
2019-09-15T13:58:38 < specing> jpa-: its the same with Ada
2019-09-15T13:58:45 < specing> jpa-: once it passes the compiler, it works
2019-09-15T13:59:02 < specing> no or very minimal bugs
2019-09-15T13:59:32 < jpa-> specing: yeah, but the experience is different
2019-09-15T14:00:13 < jpa-> in ada, the constructs are quite high level and if you use them, code is safe even if somewhat inefficient sometimes
2019-09-15T14:00:52 < jpa-> in rust, you can write precisely controlled low-level code, but because it then tries to prove it works, it just ends up refusing a lot of code
2019-09-15T14:01:05 < specing> Err, what? In Ada, one of the few languages with standardised inline asembly? :P
2019-09-15T14:01:19 < karlp> mrus: on holidays sorry. i ciuldnt figure out how to get spi slave with a gpio for chip select.  i couldnt resync the spi rx state machine.  ( or figure it out at least)
2019-09-15T14:01:27 < specing> Ada has both high level stuff (threading) and low level stuff (assembly)
2019-09-15T14:01:34 < jpa-> specing: i hope you are not trying to claim that the safety of ada applies to the low level inline assembly?
2019-09-15T14:01:38 < karlp> im sure it would work with the actual nss pin
2019-09-15T14:01:55 < specing> don't forget it was designed to run on embedded hardware in the first place
2019-09-15T14:01:58 < karlp> no fuller answers for another week sorry
2019-09-15T14:02:24 < specing> jpa-: The assembly interface is there. You are not required to use it, obviously.
2019-09-15T14:02:43 < specing> jpa-: I only use it to turn on/off global interrupts as a means of locking
2019-09-15T14:02:48 < jpa-> specing: i'm just saying, if you want to take advantage of ada's safety claims, you end up using the high-level primitives - but in rust, it is quite normal to use lower level constructs that try to be safe despite that
2019-09-15T14:03:14 < specing> jpa-: which high-level primitives are you referring to?
2019-09-15T14:03:18 < mrus> karlp: thanks for the feedback, appreciate it! Will try to figure out and eventually write stuff down in a blog post or something. This seems to be another hidden treasure of STM32. Enjoy your holidays! :-)
2019-09-15T14:03:23 < specing> if statements? loops?
2019-09-15T14:03:33 < jpa-> specing: data structures
2019-09-15T14:03:35 < learningc> jpa-, another question, when compiling a stand alone application that will run after a bootloader, there will be a startup code. Since there is a startup code for the bootloader part, won't the startup code of the application conflict with the one defined for the bootloader?  In that case, should we create the application without a startup code?
2019-09-15T14:04:10 < specing> jpa-: you mean like records or actual high level stuff like maps, sets, lists?
2019-09-15T14:05:29 < jpa-> specing: maps, sets, lists level - and especially strings
2019-09-15T14:05:50 < specing> jpa-: safety stems from its strong typing, you are not required to use maps,sets,lists to get safety
2019-09-15T14:07:04 < specing> things like the language bitching if your switch/case statement does not cover all the options or if you get an overflow in some arithmetic
2019-09-15T14:07:28 < specing> I actually get warnings about possible runtime errors before they happen - in IDE
2019-09-15T14:07:42 < specing> so I can change the code before actually flashing it
2019-09-15T14:07:46 < karlp> BrainDamage: slack did have an irc bridge but they shutbit down. they have andocumenteded websockets api instead. weechat has a very nice plugin for it.
2019-09-15T14:08:19 < jpa-> most of my refused compilations with rust have been caused by the mutability tracking - compared to "const correctness" in C++, rust is on whole different level; but i'm not sure about ada, i don't remember it having much of mutability tracking
2019-09-15T14:09:48 < benishor> learningc: 1K would be more than enough
2019-09-15T14:11:12 < specing> jpa-: glancing over this https://doc.rust-lang.org/book/ch03-01-variables-and-mutability.html and I'm not sure what this mutability tracking adds over simply marking things as constant
2019-09-15T14:11:35 < karlp> someone remind me latet about thorn/dongs power switch chats to save it
2019-09-15T14:11:41 < specing> while in Ada, variables are mutable by default with the exception of "in" parameters to functions
2019-09-15T14:12:36 < jpa-> specing: it does help with multithreaded code, though IMO going the ada way of message passing would be better
2019-09-15T14:12:40 < karlp> nvm. figured out vi on the phone
2019-09-15T14:12:58 < jpa-> specing: i'm not so sure about the advantages of rust's strict mutability tracking, but it sure adds a lot of effort into designing code
2019-09-15T14:13:45 < jpa-> like, you can't have multiple mutable pointers to one object in rust in the normal case
2019-09-15T14:14:21 < specing> jpa-: so, it adds effort for the sake of adding effort? :P
2019-09-15T14:14:36 < jpa-> it seems so to me - i'm not entirely convinced on rust so far :)
2019-09-15T14:14:44 < jpa-> https://manishearth.github.io/blog/2015/05/17/the-problem-with-shared-mutability/   tries to argue why it's useful
2019-09-15T14:16:12 < jpa-> specing: in my experience, in ada it's much easier to get used to the constructs and ways you are allowed to do things; in rust the ownership tracking (which mutability tracking and lifetime tracking are part of) is so complex that i'm having trouble following it, and the compiler cannot follow it either in all cases
2019-09-15T14:16:42 < benishor> what's wrong with C?
2019-09-15T14:16:48 < benishor> or C++ for that matter
2019-09-15T14:17:06 < jpa-> benishor: crashes
2019-09-15T14:17:11 < jpa-> and undefined behavior
2019-09-15T14:17:13 < benishor> caused by?
2019-09-15T14:17:20 < jpa-> by bad code
2019-09-15T14:17:33 < benishor> well, that's true in all languages no?
2019-09-15T14:17:53 < jpa-> in "safe" languages, the damage caused by bad code can be much more easily limited
2019-09-15T14:18:21 < specing> The C/C++ crashes aren't caused by "bad code"
2019-09-15T14:18:41 < specing> they are caused by ambiguities in the language itself causing you to fall into the undefined behavior pits
2019-09-15T14:18:51 < jpa-> in C,     void set_motor_speed(bool on) { TIM1->CCR = on ? 600 : 0; }    can set TIM1->CCR to 5000 if another piece of code elsewhere has made a mistake
2019-09-15T14:18:56 < benishor> those are relatively few afaik
2019-09-15T14:19:05 < benishor> and you're completely safe if you follow some sane guidelines
2019-09-15T14:19:35 < benishor> jpa-: how?
2019-09-15T14:19:37 < specing> benishor: hundreds of CVEs later...
2019-09-15T14:19:43 < jpa-> (ok, not to 5000, but it can set it to 5400)
2019-09-15T14:20:07 < jpa-> benishor: by having a bool variable somewhere accidentally overwritten by a value that is not 0 or 1
2019-09-15T14:20:49 < specing> That sounds like a hilarious issue
2019-09-15T14:20:53 < specing> got a testcase for it? :P
2019-09-15T14:20:57 < benishor> if your structure is fine then chances you run into that would be extremely small
2019-09-15T14:21:11 < benishor> I have yet to see an instance of that
2019-09-15T14:21:22 < benishor> in 20+ years of writing code
2019-09-15T14:21:35 < jpa-> specing: when fuzzing nanopb i was constantly being hit by it - but i'm not sure what to do about it, except not use 'bool'
2019-09-15T14:22:21 < benishor> how about getting to the root cause of it?
2019-09-15T14:22:37 < benishor> as in who wrote over it?
2019-09-15T14:22:54 < jpa-> root cause is that i've declared the input structs to the library as untrusted data, i.e. shouldn't crash even if there is random data there
2019-09-15T14:23:19 < jpa-> it would be much easier to write code assuming that there is never any error anywhere, but that is not true in real world
2019-09-15T14:23:28 < jpa-> instead, one has to try to contain the damage an error can cause
2019-09-15T14:24:05 < benishor> it depends on the context. if the code is not to be shared in the wild and you control the input you are safe to assume there will not be errors
2019-09-15T14:24:29 < jpa-> that's not true for most code in the world
2019-09-15T14:25:11 < jpa-> almost every system communicates with other systems, or components written by other people - but i really don't trust myself either, i make plenty of bugs
2019-09-15T14:26:53 < learningc> benishor, then either you use the backup sram or the flash. Backup ram needs a battery to keep it. Flash don't. But do you need to rewrite often?
2019-09-15T14:28:05 < benishor> learningc: not often. I would assume an order of writes of 10k 
2019-09-15T14:28:16 < benishor> is that too much for the flash?
2019-09-15T14:28:44 < benishor> jpa-: then let it crash. better have it blow up than silent fail
2019-09-15T14:28:50 < benishor> offensive programming to the rescue
2019-09-15T14:29:33 < learningc> benishor, no, the flash endurance I believe is in 100K if I'm not mistaken. Check the datasheet for flash endurance
2019-09-15T14:29:34 < jpa-> benishor: crash? but it doesn't crash
2019-09-15T14:29:50 < jpa-> benishor: it just sets wrong value to register in a way that one wouldn't expect, and keeps going
2019-09-15T14:30:42 < jpa-> (i know i said "shouldn't crash" but should have really written "shouldn't crash, overwrite memory or act otherwise erratically")
2019-09-15T14:31:17 < karlp> öheh, benishor clearly hasnt been bitten enough by c yet :)
2019-09-15T14:31:36 < learningc> benishor, if you need better endurance you could always alternate the flash location. example, first flash write in area 1, second flash write in area 2, then alternate
2019-09-15T14:31:36 < benishor> I would simply add an extra indirection layer
2019-09-15T14:32:10 < benishor> which would allow me to control the writes on the target register
2019-09-15T14:33:17 < benishor> every problem is solvable if you add extra indirection layers. you gain flexibility at the cost of some performance
2019-09-15T14:33:37 < benishor> learningc: thanks for the tip, it's a good idea!
2019-09-15T14:34:37 < jpa-> benishor: sure, one can solve that particular problem by writing  volatile int foo = on;  to bypass the potential undefined behaviour - but that would be just silly, there are plenty other pitfalls waiting
2019-09-15T14:34:50 < jpa-> if such level of protection between pieces of code is needed, one needs a safer language
2019-09-15T14:39:03 < benishor> my embedded experience is quite limited so perhaps I have yet to run into voracious bugs
2019-09-15T14:39:43 < jpa-> it also totally depends on what kind of stuff you make
2019-09-15T14:40:06 < jpa-> for all the crap i do, it doesn't matter at all if it has some bugs, which is why i just use C and C++ still
2019-09-15T14:40:37 < jpa-> but i certainly hope that people making e.g. safety critical embedded stuff, or anything that communicates with internet, would have better languages available
2019-09-15T14:41:31 < jpa-> and if the languages ever progress to a point where "debugging time saved" is more than "time spent satisfying the compiler", it would make sense to switch
2019-09-15T14:42:39 < jpa-> IMO rust is not there yet - ada might be, but the cost of switching and lack of good libraries etc. makes the threshold high

2019-09-15T20:49:18 < Datz> Hi, I'm using stm32duino and have noticed that ADC values appear to be low when compared from Vcc to gnd. Does anyone else use stm32duino, and has noticed this?
2019-09-15T20:50:17 < Cracki> can you be more precise
2019-09-15T20:52:06 < Datz> Sure, it is outlined here actually: https://github.com/stm32duino/Arduino_Core_STM32/issues/651
2019-09-15T20:53:37 < Datz> Noticed it trying to read a thermistor
2019-09-15T20:56:45 < jpa-> Datz: for 50kohm input impedance, you need a long sample time
2019-09-15T20:56:57 < jpa-> the datasheet recommends max 10kohm input impedance for good accuracy
2019-09-15T20:57:08 < Datz> interesting 
2019-09-15T20:57:19 < Datz> so sample time may be the issue?
2019-09-15T20:58:21 < Datz> let's try it..
2019-09-15T20:58:57 < jpa-> the ADC puts a drain of 4pF * 1.6V * samplerate on the divider, which would quite much match your 0.3V difference if you have the sample time at minimum ~1µs setting

2019-09-15T22:17:30 < Steffanx> Comes with a regulator. At least the efm32gh322somethingsomething does
2019-09-15T22:20:55 < kakimir> yes
2019-09-15T22:21:04 < kakimir> same thing with certain efm8 model
2019-09-15T22:21:11 < kakimir> something something
2019-09-15T22:21:21 < kakimir> and costs like half an euro

2019-09-15T22:24:28 < Datz> Cracki: so looks like I have to put those changes in build_opt.h Seems like I can't just stick them in there under the same syntax?
2019-09-15T22:24:44 < Cracki> why are you asking me
2019-09-15T22:25:02 < Steffanx> lol
2019-09-15T22:25:04 < Cracki> ask these frenchmen who control the project
2019-09-15T22:25:57 < Cracki> they implemented every way to get firmware onto an F103-based board EXCEPT via usb and flash bootloader
2019-09-15T22:26:17 < Cracki> the flash bootloader used to work before ST touched it, then it took them at least a year to get it working again
2019-09-15T22:27:04 < Datz> Well.. at least I know why the ADC values seemed off.. I guess that's a step in the right direction.
2019-09-15T22:27:12 < Cracki> it's supposed to be a fucking arduino, and they're supposed to be flashable through the fucking usb port on the fucking board
2019-09-15T22:27:42 < Cracki> they amaze me.
2019-09-15T22:28:04 < Datz> I don't know enough to complain.. lol
2019-09-15T22:28:26 < Cracki> their first level support isn't even indian
2019-09-15T22:28:47 < Datz> Using an STLink and getting serial out of the usb.. it works
2019-09-15T22:28:51 < Cracki> 'excuse me you have an error in your datashit. changes this to that" and they ask  me what fucking company I represent
2019-09-15T22:29:06 < Datz> heh
2019-09-15T22:32:27 < kakimir> Steffanx: planning to make my first usb device
2019-09-15T22:32:37 < kakimir> usb business card
2019-09-15T22:33:20 < kakimir> I don't know what it will do but it must be slick -> sandwich burried components etc
2019-09-15T22:34:03 < kakimir> it needs to fit inside normal card pockets
2019-09-15T22:34:39 < Cracki> get nfc cards
2019-09-15T22:34:56 < kakimir> nfc business card?
2019-09-15T22:35:27 < kakimir> you tap that with phone and phone says contact information has been received?
2019-09-15T22:35:57 < fenugrec> what was wrong with QR business card
2019-09-15T22:36:03 < Steffanx> its not fancy.
2019-09-15T22:36:23 < Steffanx> dont forget to mount the tqfp package upside down, kakimir
2019-09-15T22:36:30 < kakimir> yes
2019-09-15T22:36:40 < kakimir> and no
2019-09-15T22:36:44 < Cracki> you can make nfc chips do more than just store stuff
2019-09-15T22:36:53 < Cracki> it's just a little low power
2019-09-15T22:37:26 < kakimir> usb businesscard keystroke injector
2019-09-15T22:37:28 < Cracki> no idea about how much power nfc can put into a tag but it might be enough for slow displays
2019-09-15T22:37:45 < Steffanx> what business are you in soon, kakimir?
2019-09-15T22:38:07 < kakimir> I plan to go to layout jubb
2019-09-15T22:38:39 < englishman> data matrix > qr
2019-09-15T22:39:18 < englishman> kakimir: just do a cool design in enig on black 20mil fibreglass
2019-09-15T22:39:23 < englishman> looks amazing
2019-09-15T22:39:33 < englishman> esp with 3/3 clearance
2019-09-15T22:39:59 < kakimir> no usbs?
2019-09-15T22:40:12 < Steffanx> fuck esp
2019-09-15T22:40:34 < kakimir> ENIG without solder mask
2019-09-15T22:40:39 < kakimir> get that old look
2019-09-15T22:40:47 < Steffanx> Recommending to use Keil, Recommending to use ESP. Make up your mind englishman :P
2019-09-15T22:40:58 < kakimir> what is ESP?
2019-09-15T22:41:09 < Steffanx> i assumed some espwahtever module
2019-09-15T22:41:10 < kakimir> other than fun button in car
2019-09-15T22:41:36 < englishman> no usb plug is going to be the thickness of a business card nor do I want to plug a business card into my computer/phone
2019-09-15T22:42:01 < englishman> yeah kakimir enig without soldermask on black 20mil pcb
2019-09-15T22:42:12 < Steffanx> it has been done and worked fairly well...
2019-09-15T22:42:33 < englishman> link?
2019-09-15T22:42:59 < Steffanx> i mean, the pcb style usb connector stuff. Has been some so many times that im not even gonna link it.
2019-09-15T22:43:57 < englishman> not really the thickness of a bizcard tho isn't it 1.2mm
2019-09-15T22:44:14 < englishman> nor the shape of a bizcard
2019-09-15T22:44:21 < englishman> all that shit is dumb
2019-09-15T22:44:26 < qyx> I would ban all those incomplete USB connectors
2019-09-15T22:44:32 < Steffanx> business cards are dumb.
2019-09-15T22:45:18 < kakimir> yes
2019-09-15T22:45:37 < kakimir> I need to get back to freertos project I had a while aho
2019-09-15T22:45:39 < kakimir> ago
2019-09-15T22:46:43 < kakimir> business cards just wear out in the pocket of wallet
2019-09-15T22:46:53 < kakimir> then you throw them away
2019-09-15T22:48:12 < kakimir> pamphlet is better
2019-09-15T22:49:00 < BrainDamage> my personal experience in pitchin sales, people wanted more the business cards than the pamphlets
2019-09-15T22:49:14 < kakimir> yes
2019-09-15T22:49:34 < kakimir> don't give that awkward pile of paper
2019-09-15T22:49:49 < englishman> maybe write a book about yourself and give it away to potential employers
2019-09-15T22:50:02 < englishman> or a large poster
2019-09-15T22:50:06 < kakimir> oh wow
2019-09-15T22:50:16 < kakimir> that is creative
2019-09-15T22:50:27 < englishman> Brew some beer that represents your talents and put your resume on the can
2019-09-15T22:50:42 < kakimir> in china business cards were a ritual of it's own
2019-09-15T22:50:56 < BrainDamage> in japan too, it's considered a proxy of the person
2019-09-15T22:51:11 < englishman> grow some magic mushrooms that make people hallucinate the ideal employee, you
2019-09-15T22:51:11 < BrainDamage> which is insanity
2019-09-15T22:51:14 < kakimir> it must be given with both hands with slight bow
2019-09-15T22:51:27 < kakimir> also received similarry
2019-09-15T22:51:44 < englishman> give away lab mice with your work history encoded into their dna
2019-09-15T22:52:08 < kakimir> you must inspect the card for a while and then put it carefully away in your pocket or so
2019-09-15T22:52:31 < englishman> buy a domain kakimircreates.software and write a moody wordpress blog
2019-09-15T22:52:38 < kakimir> englishman has it figured out already
2019-09-15T22:53:08 < BrainDamage> dust the business card with urushiol oil and protect your fingers with a layer of transparent glue
2019-09-15T22:54:04 < englishman> invite people to a cocaine party on your private Caribbean island then blackmail them using pictures you secretly took of them with underage whores
2019-09-15T22:59:57  * Datz gives up for the day..
2019-09-15T23:02:09 < kakimir> oh wow my mouse is back
2019-09-15T23:02:33 < kakimir> englishman: where do you get all these good ideas?

2019-09-15T23:33:33 < catphish> hey humans, i have a totally off topic programming question, i want to write a network server, it accepts connections, then clients send requests down those connections, the part i'm unclear about is how to allocate memory for these requests, an individual request may be up to 50MB, and they are terminated by newlines, it's not really clear to me how to handle this situation with regard to reading the incoming data and storing it somewhere for 
2019-09-15T23:33:33 < catphish> processing
2019-09-15T23:45:37 < Cracki> wat
2019-09-15T23:45:52 < Cracki> you're being vague. is this a matter of national security?
2019-09-15T23:46:09 < Cracki> https://en.wikipedia.org/wiki/C10k_problem
2019-09-15T23:46:16 < Cracki> you have lots of options

2019-09-15T23:47:53 < Cracki> fork a process, start a thread, some kind of coroutine, some explicit way to handle connection state (not as code simply running as if uninterrupted)
2019-09-15T23:49:01 < catphish> my concern is purely about memory allocation
2019-09-15T23:49:06 < Cracki> fuck that
2019-09-15T23:49:10 < Cracki> just collect it
2019-09-15T23:49:21 < Cracki> what language
2019-09-15T23:49:31 < catphish> ideally C
2019-09-15T23:49:35 < Cracki> lol ok
2019-09-15T23:49:54 < catphish> a client has connected, i see that it wants to send me some data, but i don't know how much memory to allocate because the request could be *any* length
2019-09-15T23:50:13 < Cracki> first distinction: used memory vs allocated memory.
2019-09-15T23:50:32 < Cracki> stl vectors (c++) have that. they don'y reallocate every time you push or pop anything
2019-09-15T23:50:59 < Cracki> make a struct, pointer to memory, size of used, size of allocated
2019-09-15T23:51:24 < Cracki> make some functions that enlarge it either in fixed sized blocks or do a doubling of capacity when needed
2019-09-15T23:51:35 < Cracki> memcpy what you receive into it, adjust "used" size
2019-09-15T23:52:55 -!- futarisIRCcloud [uid222239@gateway/web/irccloud.com/x-vuvjbcrboxyznwmz] has joined ##stm32
2019-09-15T23:52:57 < Cracki> handle return values of realloc properly (i.e. end the connection if it hasn't enlarged)
2019-09-15T23:53:39 < Cracki> I'd tell you to use any other language but C
2019-09-15T23:53:50 < catphish> well right now i have this server in ruby
2019-09-15T23:53:53 < catphish> but it's too slow :(
2019-09-15T23:53:57 < Cracki> fuck ruby
2019-09-15T23:54:20 < Cracki> try anything that's higher level than C.
2019-09-15T23:54:26 < Cracki> and anything that's better engineered than ruby.
2019-09-15T23:54:29 < catphish> so i need a language that can do multithreading and won't take an age to move binary string data around
2019-09-15T23:54:38 < Cracki> multithreading to do what
2019-09-15T23:54:50 < Cracki> nothing takes ages to memcpy data
2019-09-15T23:54:58 < catphish> well multithreading isn't important if one thread is fast enough :)
2019-09-15T23:55:09 < catphish> just to handle more clients
2019-09-15T23:55:18 < Cracki> python has a gil but python's multithreading is still a useful abstraction, especially if libraries release that interpreter lock
2019-09-15T23:55:26 < Cracki> how many concurrent clients 
2019-09-15T23:55:45 < catphish> hundreds (ish)
2019-09-15T23:55:46 < Cracki> (don't bother fucking with python's async/await and whatnot, that's a fucking nightmare)
2019-09-15T23:55:53 < Cracki> k then do threads maybe
2019-09-15T23:56:13 < Cracki> or maybe take a look at what "tcp server" implementations there are
2019-09-15T23:56:38 < Cracki> the py standard library probably has something that does the select/poll and stuff already
2019-09-15T23:56:51 < Cracki> what does a connection do?
2019-09-15T23:56:55 < Cracki> anything complicated?
2019-09-15T23:57:10 < catphish> i could probably alloc the maximum allowed memory size when a client starts to send a request, copy the request into that memory as it arrives, then when the request is finished, free it (and if i over-read, reading some of another request), copy that into a new request buffer first
2019-09-15T23:57:28 < catphish> specifically this program is a redis proxy
2019-09-15T23:57:35 < Cracki> a proxy
2019-09-15T23:57:43 < Cracki> have you looked for redis proxies yet?
2019-09-15T23:58:01 < Cracki> or general kinds of proxy?
2019-09-15T23:58:13 < Cracki> typically you don't have to buffer shit if it's a proxy, just pipe it through
2019-09-15T23:58:14 < catphish> it accepts connections, accepts redis requests over those connections, then proxies them to a redis backend server
2019-09-15T23:58:29 < Cracki> don't buffer anything
2019-09-15T23:58:35 < catphish> streaming might actually work
2019-09-15T23:58:40 < Cracki> it must
2019-09-15T23:58:43 < Cracki> do NOT buffer anything
2019-09-15T23:58:56 < catphish> well i have to buffer something, but perhaps not much
2019-09-15T23:58:56 < Cracki> and DO look for existing software that does what you want
2019-09-15T23:59:01 < Cracki> no you won't
2019-09-15T23:59:15 < Cracki> you read, then you write and make sure you write everything
2019-09-15T23:59:40 < Cracki> sockets are fucky, they may send less than you asked, then you have to make sure to send the remainder, until everything was sent
2019-09-15T23:59:50 < Cracki> same for read. reads can read less than the full buffer (obviously)
--- Day changed Mon Sep 16 2019
2019-09-16T00:00:06 < Cracki> and they often do read less, even if you think you haven't sent that much
2019-09-16T00:00:44 < Cracki> google "redis proxy"
2019-09-16T00:00:47 < Cracki> bunch of result
2019-09-16T00:00:48 < Cracki> s
2019-09-16T00:02:46 < Cracki> do stay away from any "go" code. go is even more of a code money's language than java was meant to be.
2019-09-16T00:02:58 < catphish> lol
2019-09-16T00:03:13 < Cracki> google explicitly states this.
2019-09-16T00:03:38 < Cracki> only reason they don't use java is probably because it required too much understanding.
2019-09-16T00:03:43 < karlp> catphish: fuck doing serverside shit in c until uour proof of concept fails
2019-09-16T00:04:06 < catphish> karlp: my ruby POC just hit its performance limits :)
2019-09-16T00:04:27 < Cracki> if you buffer, I'm sure it'll hit some limits
2019-09-16T00:04:29 < catphish> usually i got Ruby -> C
2019-09-16T00:04:37 < Cracki> does ruby have binary strings or buffers?
2019-09-16T00:04:57 < catphish> ruby has strings, it doesn't necessarily care what's in them
2019-09-16T00:04:58 < Cracki> show some code
2019-09-16T00:05:04 < Cracki> maybe it's not ruby, maybe it's you
2019-09-16T00:05:19 < Cracki> what limits did you hit... specifically?
2019-09-16T00:05:42 < catphish> just the "my code is using 100% of a cpu core" limit
2019-09-16T00:05:56 < Cracki> kek
2019-09-16T00:05:58 < Cracki> show code
2019-09-16T00:06:11 < catphish> it's plausible that i can make changes to avoid so many string duplications
2019-09-16T00:06:20 < Cracki> if it does that with zero or one client...
2019-09-16T00:06:33 < catphish> huh?
2019-09-16T00:06:37 < Cracki> show code
2019-09-16T00:06:43 < catphish> i said hundreds
2019-09-16T00:06:46 < Cracki> pants down
2019-09-16T00:06:49 < catphish> unfortunately this one is nonfree
2019-09-16T00:07:18 < Cracki> the best things in life are nonfree
2019-09-16T00:07:29 < Cracki> that's why god invented dungeons
2019-09-16T00:07:32 < catphish> my question is more specific, how to allocate memory for a line buffered network protocol in c
2019-09-16T00:07:40 < Cracki> told you
2019-09-16T00:07:52 < Cracki> assume a sensible first size, then manage any increase
2019-09-16T00:08:20 < Cracki> the typical implementations either say fuck you to lines beyond a certain size, or they handle it with realloc
2019-09-16T00:08:21 < catphish> i think i can do that, and for overread, i can just copy the excess into a new buffer before freeing the old one
2019-09-16T00:08:28 < Cracki> what's "overread"
2019-09-16T00:08:42 < Cracki> the situation you describe can't happen
2019-09-16T00:08:46 < catphish> so, requests are line-based, they end with \r\n
2019-09-16T00:09:24 < Cracki> before doing a read()/recv(), increase your buffer so it has at least X free, then read into that at the exact location
2019-09-16T00:09:24 < catphish> but if i read(socket, memory, 10240) to get 10KB, i may read into the next request if the client is pipelining
2019-09-16T00:09:33 < Cracki> ah
2019-09-16T00:09:49 < Cracki> you need to split lines
2019-09-16T00:09:54 < Cracki> why do you even care about this, it's a proxy?
2019-09-16T00:09:55 < catphish> right
2019-09-16T00:09:58 < Cracki> stream shit.
2019-09-16T00:10:14 < Cracki> otherwise, yes, you need an fgets() or something on the socket
2019-09-16T00:10:29 < catphish> fgets is basically exactly what i want
2019-09-16T00:10:31 < Cracki> i.e. read/recv, then scan what you got for linebreaks
2019-09-16T00:11:17 < Cracki> then call whatever handles a line with a pointer and length and maybe insert a null in place of the newline (or copy the stuff to another buffer which I find wasteful)
2019-09-16T00:11:43 < catphish> well when the request it done, i really need to free the buffer
2019-09-16T00:11:50 -!- bitmask [~bitmask@c-73-215-237-27.hsd1.nj.comcast.net] has quit [Quit: Bye!]
2019-09-16T00:11:51 < Cracki> whatever's part of the next line you can copy to the beginning of the buffer, or allocate a new buffer and copy there
2019-09-16T00:11:52 < catphish> can't just keep old requests in the buffer indefinitely
2019-09-16T00:12:01 < Cracki> or figure out if redis has a line length limit
2019-09-16T00:12:15 < catphish> right, i was thinking just copy to the start of a new buffer and free the old one
2019-09-16T00:12:21 < Cracki> I'd tell you to consider a ring buffer
2019-09-16T00:12:29 < catphish> redis may have a limit, but i have my own (64MB) that nobody has ever complained about
2019-09-16T00:12:44 < Cracki> but ring buffers assume that code can handle the wraparound
2019-09-16T00:12:52 < catphish> the problem with a ring buffer is that it means all clients will use a minimum of 64MB at all times
2019-09-16T00:12:53 < Cracki> and why do you even linebuffer?
2019-09-16T00:12:59 < Cracki> stop the buffering, just pipe through
2019-09-16T00:12:59 < catphish> (exactly 64MB) at all times
2019-09-16T00:13:38 < catphish> so, the reason for the line buffer is that i need to know where the beginning of each line is so that i can handle some requests in my proxy, and modify others
2019-09-16T00:13:44 < Cracki> you aren't doing anything to the data
2019-09-16T00:13:48 < Cracki> ah
2019-09-16T00:13:55 < Cracki> then you do need this
2019-09-16T00:13:59 < Cracki> at least partially
2019-09-16T00:14:00 < catphish> it's not just a TCP proxy, if it was i'd use haproxy :)
2019-09-16T00:14:12 < Cracki> is there a way to decide what needs doing, BEFORE the whole line has been read?
2019-09-16T00:14:23 < catphish> what it actually does is to prefix poeople's REDIS keys with a prefix to allow them to multihome
2019-09-16T00:14:28 < Cracki> srsly this sounds like even ruby can do it without hitting 100%
2019-09-16T00:14:58 < Cracki> so insert things? no replacement or deletion?
2019-09-16T00:15:49 < Cracki> the only part of this that needs huge buffers is data and you don't touch that, only keys/metadata, right?
2019-09-16T00:16:07 < catphish> this is how i line buffer in ruby https://paste.ubuntu.com/p/kPKCdjJQpV/
2019-09-16T00:16:24 < catphish> it feels efficient, but i'm not convinced it is
2019-09-16T00:16:47 < catphish> i have no idea where my bottleneck actually is though
2019-09-16T00:17:05 < catphish> could be in the redis client library i use for the other end of the connection
2019-09-16T00:17:12 < Cracki> that's for splitting. where do you append?
2019-09-16T00:17:16 < Cracki> use a profiler
2019-09-16T00:17:36 < Cracki> or sprinkle gettickcount/equivalent in your code
2019-09-16T00:17:57 < Cracki> see if you have any busy loops in there
2019-09-16T00:18:03 < Cracki> a read/recv should block, if it's in a thread
2019-09-16T00:18:15 < Cracki> if you have nonblocking read/recv, you need a select/poll
2019-09-16T00:18:22 < Cracki> to only read/recv from those that have data
2019-09-16T00:18:36 < catphish> this is my generic event loop and event loopable socket that i use in all my prototypes https://paste.ubuntu.com/p/BfbGmfqMVN/
2019-09-16T00:19:16 < Cracki> does that busyloop and cause 100% cpu anywhere else?
2019-09-16T00:19:56 < catphish> not at all, it's event driven with linux's epoll
2019-09-16T00:20:06 < Cracki> good
2019-09-16T00:20:07 < catphish> the read/append is a simple @read_buffer << @socket.read_nonblock(1048576)
2019-09-16T00:20:17 < Cracki> you need a profiler
2019-09-16T00:20:21 < catphish> makes sense
2019-09-16T00:20:26 < Cracki> uh
2019-09-16T00:20:37 < Cracki> read_nonblock, is that ever called WITHOUT knowing there's data?
2019-09-16T00:20:45 < Cracki> otherwise this would keep appending empty strings
2019-09-16T00:21:00 < catphish> it's called any time epoll says data is waiting
2019-09-16T00:21:18 < Cracki> throw some timing measurements into everything, if you don't have a profiler
2019-09-16T00:21:32 < catphish> the event loop code is good :)
2019-09-16T00:21:44 < catphish> but something in the redis line handling or proxying is bad
2019-09-16T00:22:11 < Cracki> profile it
2019-09-16T00:22:58 < catphish> this looks handy https://ruby-prof.github.io/
2019-09-16T00:24:46 < Cracki> joutube thinks I want to see this https://www.youtube.com/watch?v=WVz8rvIl_vY
2019-09-16T00:25:00 < Cracki> it's not quite a fox
2019-09-16T00:25:25 < catphish> back to testing and writing codes :)
2019-09-16T00:25:44 < Cracki> I'm confident that ruby can do what you want :P
2019-09-16T00:26:15 < Cracki> I know people who make php do the same things
2019-09-16T00:28:27 < catphish> i'm inclined to agree, i push a lot of data through ruby every day
2019-09-16T00:28:52 < Cracki> if the split turns out to be it, that can be optimized
2019-09-16T00:29:26 < Cracki> search just the new part, get index, split new part there and glue to existing
2019-09-16T00:30:11 < Cracki> better split on \n only then, and don't remove that char from the buffer
2019-09-16T00:35:47 < karlp> catphish: thanks for doing a high level poc first. so lively to see :)
2019-09-16T00:37:11 < karlp> so luvverly, better typing required
2019-09-16T00:38:09 -!- sterna [~Adium@c-95e1e253.016-35-62726f1.bbcust.telenor.se] has quit [Quit: Leaving.]
2019-09-16T00:38:20 < catphish> lol, karlp i write a lot of servers, my ruby is fairly good, i rarely find they need to be changed to low level, but it happens sometimes
2019-09-16T00:38:35 < catphish> but i do wonder if i should make more effort to optimize this first
2019-09-16T00:40:09 < karlp> can you still change the api with the clients?
2019-09-16T00:40:25 < karlp> newline based at 50k sounds problem orone
2019-09-16T00:40:52 < karlp> are yiy trying to do raw tcp or what?
2019-09-16T00:41:39 < karlp> how did you decide it was a memory alloc petf problem? cachegrind?
2019-09-16T00:43:22 < catphish> the frontend and backend API are both redis
2019-09-16T00:43:59 < catphish> i'm proxying redis, adding support for authentication and multitenanting that redis can't provide
2019-09-16T00:44:40 < catphish> so the protocols are set in stone, the commands being newline terminated is annoying
2019-09-16T00:45:24 < Cracki> oh btw, you need to split until there's nothing left to split. multiple lines may be in a single read/recv
2019-09-16T00:45:34 < Cracki> can't remember if the code does that or not
2019-09-16T00:45:49 < catphish> there are some little things i do that could well be costing me big on performance: write(":#{result}\r\n")
2019-09-16T00:45:58 < Cracki> uh
2019-09-16T00:46:02 < Cracki> a format string?
2019-09-16T00:46:06 < catphish> this just wraps a response and sends it along

2019-09-16T00:46:09 < Cracki> I'm sure that'll cost you
2019-09-16T00:46:25 < catphish> but it means an extra string has to be created and immediately garbage collected again
2019-09-16T00:46:34 < Cracki> that shouldn't matter
2019-09-16T00:46:41 < catphish> perhaps
2019-09-16T00:46:44 < Cracki> is result 50 MB or less than a handful of bytes?
2019-09-16T00:46:56 < catphish> can be around a MB
2019-09-16T00:47:02 < Cracki> profiler.
2019-09-16T00:47:09 < Cracki> you need facts.
2019-09-16T00:49:01 < catphish> especially when write does this:   @write_buffer << data.force_encoding('BINARY') so yet another copy of that data :)
2019-09-16T00:49:36 < Cracki> but only of the chunk you received, and only if whatever produces it hasn't already set binary encoding on it
2019-09-16T00:49:51 -!- nashpa [~nashpa@dliviu.plus.com] has joined ##stm32
2019-09-16T00:50:00 < Cracki> unless ruby doesn't check that case and always does a copy
2019-09-16T00:50:39 < catphish> .force_encoding('BINARY') just sets the encoding on the string, not an expensive operation
2019-09-16T00:50:41 < Cracki> what does ruby do when you append a single character/byte to a string ten million times?
2019-09-16T00:50:46 < karlp> im more curious what you didnto leave poc stage....
2019-09-16T00:50:51 < Cracki> print the iteration number every 10k iterations
2019-09-16T00:51:01 < Cracki> it should run linearly, not slow down
2019-09-16T00:51:32 < Cracki> if it does, look for a string builder. that's a common thing in java, unheard of in python because python optimizes this stuff.
2019-09-16T00:53:19 < catphish> appending should be fast, it will indeed append
2019-09-16T00:53:50 < Cracki> my point is whether it distinguishes between allocated size and used size, or not
2019-09-16T00:54:55 < catphish> i have little chance of understanding ruby's heap
2019-09-16T00:57:54 < catphish> i've got profiler output, marvellous
2019-09-16T01:00:33 < Cracki> oh btw, appending to a string in python isn't as bad as in java (where they do a copy every time because they have mutable strings so they aren't shareable)
2019-09-16T01:00:59 < Cracki> but python's io.StringIO is actually linear while += to a string does slow down
2019-09-16T01:03:31 < catphish> well, just took a massive chunk out of the cpu cost by removing logger.debug lines. logger.debug(some_function_that_dumps_data_to_a_string) will cause the inner function to run even when the logger doesn't care :)
2019-09-16T01:03:44 < catphish> so all my debug log was being generated and thrown away
2019-09-16T01:04:07 < catphish> 75% reduction in cpu usage, good times
2019-09-16T01:04:19 < zyp> I thought ruby was a language that already came and went
2019-09-16T01:04:38 < zyp> role replaced by nodejs or some shit
2019-09-16T01:05:01 < englishman> catphish, have you tried go
2019-09-16T01:05:21 < catphish> lol i have not
2019-09-16T01:05:24 < englishman> I haven't done anything big with it but to pass things between programs it's really handy
2019-09-16T01:06:06 < zyp> people make a lot of neat stuff in go, and I've looked at hacking on some of it, but I don't really get the language
2019-09-16T01:07:04 < Cracki> it's not for everyone
2019-09-16T01:07:13 < Cracki> google's better paid engineers don't use it either.
2019-09-16T01:07:19 < catphish> my stuff tends to be high level where performance doesn't matter much, i use ruby because i know it well, or very simple and low level, i use C because of its simplicity
2019-09-16T01:07:19 < englishman> you could pick up the kernighan book to get started, it's a little dated now but covers the language's concepts well
2019-09-16T01:07:33 < catphish> just occasionally i need something high performance and more complex, i get stufk
2019-09-16T01:07:35 < catphish> *stuck
2019-09-16T01:07:47 < zyp> yeah, I've got the same relationship to python and C++
2019-09-16T01:08:52 < englishman> go is pretty nice for that, as a compiled language it has an advantage but the c concepts help you write performant code too
2019-09-16T01:09:02 < catphish> i reduced the CPU cost of my program by 50% (maybe 75%), maybe somewhere in between by removing code that generates verbose log lines and discards them even when logging is disabled
2019-09-16T01:09:06 < catphish> so i'm happy for tonight
2019-09-16T01:09:17 < catphish> but i will likely figure out how to do this properly in C
2019-09-16T01:09:33 < zyp> hah
2019-09-16T01:09:40 < karlp> Cracki: "recent" java, like, anything 5+ doesnt need stringbuilder stuff like the old days
2019-09-16T01:10:09 < catphish> in the meantime i have to debug an OCFS filesystem that hangs from time to time
2019-09-16T01:10:33 < karlp> its worth remembering that shit has impacts, but cargo culting is real
2019-09-16T01:11:23 < catphish> today i ran a half marathon in 1:49 :)
2019-09-16T01:11:42 < englishman> that's quick
2019-09-16T01:11:55 < englishman> congrats
2019-09-16T01:12:23 < karlp> good job!
2019-09-16T01:12:54 < karlp> nice time, first? or furst under two? or what?
2019-09-16T01:14:36 < catphish> it's about the 4th i've done, last couple were around 1:55
2019-09-16T01:14:51 < catphish> so a decent improvement in a few weeks
2019-09-16T01:15:22 < catphish> it wasn't that difficult to go from running 10k to half marathon
2019-09-16T01:15:32 < catphish> my 10k is about 49 minutes
2019-09-16T01:15:39 < turnip420> https://www.youtube.com/watch?v=zDUxktR57u0
2019-09-16T01:16:09 < zyp> most difficult part is getting out and running in the first place
2019-09-16T01:16:34 < turnip420> lol
2019-09-16T01:17:03 < catphish> zyp: for me the main thing was losing weight, it improved my times enourmously
2019-09-16T01:17:54 < catphish> but yes, getting out im the first place i guess even more so
2019-09-16T01:18:13 < zyp> I've got more problems gaining weight than losing weight, so that's not a motivator for me
2019-09-16T01:18:49 < catphish> gaining weight is too easy for me
2019-09-16T01:19:21 < catphish> i love food and essentially have no natural desire to stop eating, so not being obese requires a little self control
2019-09-16T01:20:54 < zyp> last I checked I've lost like 4kg unintentionally over the past few weeks
2019-09-16T01:21:05 < zyp> been doing stuff nonstop since daughter was born
2019-09-16T01:21:15 < Cracki> http://www.pellegrino.link/2015/08/22/string-concatenation-with-java-8.html
2019-09-16T01:21:55 < Cracki> who knows, maybe it got smarter since java 8...
2019-09-16T01:22:56 < catphish> does fgets just repeatedly call the kernel to read(1)?
2019-09-16T01:23:32 < Cracki> libc might itself buffer
2019-09-16T01:23:33 < zyp> doesn't it do buffering?
2019-09-16T01:23:45 < Cracki> so it reads chunks and then splits lines off that
2019-09-16T01:24:00 < catphish> hopefully it has its own buffering / splitting
2019-09-16T01:24:06 < catphish> seems worth a try
2019-09-16T01:24:11 < Cracki> likely
2019-09-16T01:24:38 < Cracki> fgets works on FILE*, if we're talking C
2019-09-16T01:24:41 < catphish> i always get confused with C's "file" objects
2019-09-16T01:24:44 < Cracki> and file* isn't an fd/socket
2019-09-16T01:24:50 < catphish> indeed
2019-09-16T01:25:13 < Cracki> *just "FILE" actually, having pointers to those isn't part of the idea :P
2019-09-16T01:25:13 < catphish> maybe i need a different implementation of gets that works on an fd
2019-09-16T01:25:56 < Cracki> diy. read the socket, split it yourself
2019-09-16T01:26:03 < catphish> or meh, jus write my own buffer and split it
2019-09-16T01:26:11 < catphish> yeah what you said
2019-09-16T01:26:18 < catphish> i'll have a play
2019-09-16T01:26:27 < Cracki> what you do already is perfectly fine (unless ruby's split does anything funky)
2019-09-16T01:26:31 < catphish> it'll probably work great because i'm start
2019-09-16T01:26:35 < catphish> *smart
2019-09-16T01:27:02 < catphish> duplicating what's there now is perfect actually
2019-09-16T01:27:39 < catphish> i can make scanning for the newline more efficient by only scanning what was just appended
2019-09-16T01:27:46 < catphish> and generally go from there
2019-09-16T01:28:04 < Cracki> you're translating to C now? look at strstr and friends
2019-09-16T01:28:27 < Cracki> I think there's strchr too, haven't used any of those for a long time
2019-09-16T01:28:35 < Cracki> you might even use strtok
2019-09-16T01:28:35 < catphish> yeah, i can improve the ruby version to an extent, but ultimately this one will need to be c
2019-09-16T01:28:53 < catphish> and yes, i will make use of libc's string magic
2019-09-16T01:28:58 < Cracki> strtok would null out the separator char and give you pointers
2019-09-16T01:29:14 < Cracki> hah there's no magic to c strings, it's as dumb as it could be
2019-09-16T01:29:32 < Cracki> except for the fucking termination. I'd be happier with pascal strings (length-prefixed)
2019-09-16T01:29:38 < Cracki> there are libs that give you pstrings in C
2019-09-16T01:29:50 < catphish> basically i just want to move everything after the \n to a new string, process the current string, and free it
2019-09-16T01:30:00 < Cracki> it already has malloc/realloc/free and passing structs around is trivial because they're value types
2019-09-16T01:30:52 < mawk> [00:22:56] <catphish> does fgets just repeatedly call the kernel to read(1)?
2019-09-16T01:31:02 < mawk> only if you disabled buffering, and even then I think it's implementation defined
2019-09-16T01:31:05 < catphish> i'm probably not terrible at C, but it takes me a while to get my head around how i'll do something
2019-09-16T01:31:11 < mawk> the libc could choose to use O_NONBLOCK and read everything in chunks of 4096 bytes
2019-09-16T01:31:17 < catphish> handy
2019-09-16T01:31:23 < catphish> that's what i'll do
2019-09-16T01:31:41 < catphish> you don't even need O_NONBLOCK for that, read will return partial data afaik
2019-09-16T01:31:51 < mawk> yes if you want to read everything as soon as possible but not want to block the program, you use O_NONBLOCK
2019-09-16T01:31:54 < mawk> no
2019-09-16T01:31:55 < mawk> read() will block
2019-09-16T01:31:59 < mawk> unless the file is over of course
2019-09-16T01:32:01 < catphish> only if there's no data
2019-09-16T01:32:11 < mawk> yes, if it's a plain file it will stop at EOF, but not with a pipe/socket
2019-09-16T01:32:19 < mawk> with the latter it will block your thread
2019-09-16T01:32:20 < Cracki> read will block if there is no data. it will happily give you the data that is there and return right away, even if it's less than you wanted
2019-09-16T01:32:42 < mawk> yes in case of signal if you disable signal restart for instance
2019-09-16T01:32:45 < catphish> it's not really defined though, it can block as long as it wants and give you as much as it wants
2019-09-16T01:32:49 < Cracki> ugh signals
2019-09-16T01:32:50 < mawk> so you should check how much bytes you got and restart the read
2019-09-16T01:33:02 < Cracki> right, impldef strikes again
2019-09-16T01:33:24 < catphish> no setting it nonblock does seem sane
2019-09-16T01:33:41 < mawk> well it will probably block anyway catphish if you read and there is not enough data available
2019-09-16T01:33:45 < mawk> unless it's the end of file
2019-09-16T01:33:58 < mawk> unless you set O_NONBLOCK
2019-09-16T01:33:58 < catphish> i forget what i've observed in real life
2019-09-16T01:34:04 < catphish> but i'll set it to be sure
2019-09-16T01:34:12 < mawk> in real life read() will always block if you request more bytes than available
2019-09-16T01:34:20 < mawk> and often read() will return if you got a signal
2019-09-16T01:34:23 < catphish> are you sure?
2019-09-16T01:34:24 < mawk> but that's the exception not the norm
2019-09-16T01:34:25 < mawk> yes
2019-09-16T01:34:29 < catphish> okay :)
2019-09-16T01:34:33 < mawk> unless the file is over of course
2019-09-16T01:34:43 < mawk> or the other end closed the socket, or the pipe is closed, etc
2019-09-16T01:34:55 < mawk> if the medium is still up, read will block
2019-09-16T01:35:17 < Cracki> he's using sockets tho, not just files
2019-09-16T01:35:25 < mawk> ah, then yes with socket it will definitely block
2019-09-16T01:35:33 < mawk> until the other end closes its socket
2019-09-16T01:35:42 < catphish> the manual just says "It is not an error if this number is smaller than the  number  of  bytes  requested; this  may happen for example because fewer bytes are actually available right now (maybe because we were close to end-of-file,  or  because  we are  reading  from  a  pipe, or from a terminal)"
2019-09-16T01:35:47 < Cracki> and may return less than requested

2019-09-16T02:20:07 < Thorn> the company that made lan8720, usb2514, etc.
2019-09-16T02:20:12 < Cracki> til
2019-09-16T02:20:26 < Thorn> acquired by microchip in 2012
2019-09-16T02:20:45 < Cracki> did they kill it?
2019-09-16T02:21:24 < Thorn> the chips are still available, no idea about new products
2019-09-16T02:21:29 < Cracki> good
2019-09-16T02:21:52 < kakimir> there is some init device function in silabs sample code that like initializes peripheral registers and shiet
2019-09-16T02:22:31 < kakimir> I wonder if these 8051 chips reset all the peripherals
2019-09-16T02:23:03 < kakimir> or if the function is just application specific set
2019-09-16T02:24:09 < kakimir> but yeah that thing is dead simple to drive
2019-09-16T02:26:43 < kakimir> my question is actually that if you have ever seen mcu that doesn't reset all periph registers at reset
2019-09-16T02:28:56 < Cracki> no but that's mcus. if it's a core and the peripherals are off-chip or inside but wired to it as an afterthought, it might not do anything on its own
2019-09-16T02:29:56 < Cracki> what silabs part btw?

2019-09-16T02:37:37 < kakimir> but wrong mcus
2019-09-16T02:39:42 < Cracki> sheet section 3.8 says all registers are reset, so if they provide full init code of all registers, that might be generated and supposed to cover all bits
2019-09-16T02:40:20 < kakimir> it had parts commented
2019-09-16T02:40:36 < Cracki> "contents of ram are unaffected"... if peripheral registers aren't registers but ram locations (?) that might leave them alone
2019-09-16T02:41:16 < kakimir> I need to check
2019-09-16T02:41:22 < kakimir> boot up my code machine
2019-09-16T02:41:36 < Cracki> ah, it also says that module registers are reset, so that should be good
2019-09-16T02:41:52 < kakimir> why I'm so lazy

2019-09-16T02:48:46 < kakimir> this looks nice
2019-09-16T02:49:06 < kakimir> it sets up everything to initial state
2019-09-16T02:49:32 < kakimir> and then you just do whatever you want after init defaults has been called

2019-09-16T03:15:25 < kakimir> no chubby stm32 there
2019-09-16T03:16:18 < Cracki> grind it maybe
2019-09-16T03:17:03 < kakimir> use acid to melt that die out
2019-09-16T03:19:23 < Cracki> I am not sure if their "fomu" (fpga) is an actual fpga, or just the efm32 cortex M running code that emulates fpga

2019-09-16T03:24:18 < Cracki> the mcus i "know" (have handled) are all qfp or qfn
2019-09-16T03:25:11 < Cracki> atmegas and stm32. I've had a literal look at nrf. never had the need (or worked for anyone who did) to have small components
2019-09-16T03:25:13 < qyx> there were PICs with MAC+PHY in qfp48 or so

2019-09-16T04:29:59 < Cracki> I think it even compares favorably in terms of dmips/mhz
2019-09-16T04:30:27 < dongs> where the fuck is even linker script shit in eclipse
2019-09-16T04:30:28 < dongs> holy fuck
2019-09-16T04:30:30 < dongs> this is a total mess 
2019-09-16T04:31:37 < Cracki> heh 153 dmips at 108 mhz, that's 1.4 dmips/mhz, beats the 1.25 (?) dmips/mhz of the cortex m
2019-09-16T04:32:39 < Cracki> st marketing says 61 dmips at 72 mhz, not sure if that's right

2019-09-16T04:33:48 < Cracki> what is
2019-09-16T04:33:54 < Cracki> the busses? no clue
2019-09-16T04:34:02 < Cracki> I guess they have the license
2019-09-16T04:34:23 < kakimir> oh
2019-09-16T04:34:28 < Cracki> or it doesn't matter because they're chinese
2019-09-16T04:34:53 < kakimir> maybe it's possible that they are doing everything legally
2019-09-16T04:34:55 < Cracki> either way, they can make F103 already, and now they can make them with a different core
2019-09-16T04:35:09 < Cracki> *philosoraptor*
2019-09-16T04:35:13 < kakimir> is it illegal to implement a copy of mcu
2019-09-16T04:35:17 < kakimir> and pay for core
2019-09-16T04:35:30 < Cracki> I'm sure they didn't whiteroom-reimplement the stm32f103
2019-09-16T04:35:48 < Cracki> that's way too hard to replicate to this level of detail
2019-09-16T04:36:03 < Cracki> they got their hands on design files from ST, legally or not
2019-09-16T04:36:09 < kakimir> oh

2019-09-16T04:38:35 < dongs> how would i know
2019-09-16T04:39:04 < Cracki> lick the pins, does any of them taste like jews?
2019-09-16T04:39:40 < Cracki> newlib probably sends stdout to nowhere
2019-09-16T04:39:44 < Cracki> find the _write syscall?
2019-09-16T04:40:05 < Cracki> maybe toggling a pin/led is quicker do to

2019-09-16T05:07:53 < dongs> i just used chink parts for mine

2019-09-16T05:08:09 < mawk> that will create a .deb then you can install it grummund , then you can use update-alternatives to point the default java to it
2019-09-16T05:08:14 < grummund> what's wrong with the java i have?
2019-09-16T05:08:33 < dongs> SC8001 and SC7002
2019-09-16T05:08:43 < Cracki> i just installed jdk 12 and gave it a honest chance to optimize looped string append. it did NOT optimize that.

2019-09-16T05:09:20 < Cracki> so fuck those who seem unable to believe me
2019-09-16T05:09:25 < dongs> it does dcp/etc stuff AND current limit

2019-09-16T05:10:32 < dongs> ah

2019-09-16T05:10:37 < Thorn> might be useful in another case though, thanks
2019-09-16T05:10:42 < dongs> why would you need data in a charger?
2019-09-16T05:12:19 < Thorn> it's not just a charger
2019-09-16T05:12:35 < Thorn> it's a wireless coordinator/PLC

2019-09-16T05:18:43 < mawk> how much RAM do you have ?
2019-09-16T05:18:48 < Cracki> I wish it wouldn't randomly overwrite the syscalls.c it now generates... because I have to put shit in there to fix their shit incompatibility between freertos and newlib

2019-09-16T05:19:09 < mawk> yeah
2019-09-16T05:19:16 < mawk> yeah it generates invalid code with respect to malloc locking
2019-09-16T05:19:34 < mawk> best bet is to just not use libc functions when you use freertos if you don't have the time to study all the locking things
2019-09-16T05:19:41 < mawk> or blindly follow the webpage that tells how to do it
2019-09-16T05:19:55 < Thorn> dongs: btw those anpec switches from yesterday have a very wide range of currents for the overcurrent trigger. e.g. for the 2A switch it's 2.1...2.9A iirc. so in the worst case it's almost a 3A switch. so if I have > 1 port I can't really protect my power supply from overcurrent unless it's grossly overspecified
2019-09-16T05:20:02 < Cracki> I think it generates the syscalls.c only when it sees no project files... which i sometimes have to nuke because it flips its shit and complains about not being able to (re)generate those
2019-09-16T05:21:53 < dongs> Thorn: yea there's a few versions with different limit ranges
2019-09-16T05:22:00 < dongs> but yeah they're not exactl precise
2019-09-16T05:22:05 < dongs> worked for my application

2019-09-16T06:22:40 < Cracki> they are rounding with the 36v output yes? or can it indeed approach pass through?

2019-09-16T06:23:44 < Cracki> is their intro text wrong
2019-09-16T06:24:07 < Thorn> probably a typo there
2019-09-16T06:24:23 < Cracki> are we looking at the same datasheet
2019-09-16T06:24:32 < Cracki> abs max ratings 40 volts for vin, vout, ...

2019-09-16T06:25:06 < Thorn> maybe it's a typo in that table lol
2019-09-16T06:25:20 < Cracki> grummund, question is, does it actually work. I've been in those settings. I might need to fuck around with it more.
2019-09-16T06:25:30 < Cracki> typo
2019-09-16T06:25:40 < Cracki> wait
2019-09-16T06:25:42 < grummund> dunno, try it and report back.
2019-09-16T06:25:56 < Cracki> maybe 7.5 is somehow limited by test conditions
2019-09-16T06:26:02 < Cracki> rss1/2 = 1k
2019-09-16T06:26:16 < Cracki> does it boost? vin=12v
2019-09-16T06:26:56 < Cracki> I see no boost/stepup so they might not be as autistically literal as I am with that table

2019-09-16T06:29:52 < Cracki> hahaha that sounds familiar
2019-09-16T06:30:09 < Cracki> eclipse. you have to have the right things selected (as in "focus"), I think

2019-09-16T06:30:48 < Cracki> worth a try but it's still eclipse
2019-09-16T06:32:32 < grummund> i mean in stm32cubemx i set the toolchain as stm32cubeide and then clicked generate code
2019-09-16T06:32:48 < grummund> it loads into eclipse fine

2019-09-16T11:54:13 < grummund> just curious what that is
2019-09-16T11:54:30 < grummund> actually i kinda know what it is but not what it stands for
2019-09-16T11:55:41 < grummund> it's a CMSIS thing, apparently... "The CPDSC file format shares the schema file (PACK.xsd) with the PDSC and GPDSC format..."
2019-09-16T11:56:35 < grummund> "The Pack Description (*.pdsc) Format uses standard XML annotations ..."
2019-09-16T11:56:55 < ThatDamnRanga> Anyone who uses 'standard' and 'xml' in the same sentence is bonkers
2019-09-16T12:00:10 < grummund> aha. it is a "generator package description file"

2019-09-16T16:35:42 < nuxil> ASM question. im trying to load content from an array in memory, "ldr r0, [r2], #4"  and post increment r2 to next dword in memory. however. this synax does not work on my cortex M4. 
2019-09-16T16:35:49 < nuxil> i am getting this error: Error: Thumb does not support this addressing mode -- `ldr r0,[r2],#4'
2019-09-16T16:35:50 < nuxil>  
2019-09-16T16:36:31 < nuxil> whats up with this.,

2019-09-16T16:41:56 < fenugrec> nuxil, M4 core doesn't support that addressing mode ? I'm inclined to believe that error
2019-09-16T16:42:19 < fenugrec> you'll just have to do it in two instructions...
2019-09-16T16:45:28 < Thorn> nuxil: try ldr r0, [r2, #4]
2019-09-16T16:46:20 < nuxil> seems like i want arm mode and not thumb mode
2019-09-16T16:46:31 < nuxil> Thorn, thats not the same.
2019-09-16T16:46:43 < Thorn> cortex-m doesn't have arm mode
2019-09-16T16:46:48 < nuxil> :(
2019-09-16T16:47:17 < nuxil> so your telling me my arm cortex m4, does not have arm mode? 
2019-09-16T16:49:07 < Thorn> trying to switch to arm mode results in a usage fault iirc
2019-09-16T16:49:41 < nuxil> hmm
2019-09-16T16:49:46 < fenugrec> nuxil, PM0214 Cortex-M4 programming manual
2019-09-16T16:49:58 < fenugrec> cortex M4 != full arm ISA
2019-09-16T16:50:08 < Thorn> and arm-v7m arm
2019-09-16T16:50:21 < fenugrec> ah yes, the ARM ARM
2019-09-16T16:50:36 < Thorn> only cortex-a and cortex-r have 2 modes
2019-09-16T16:52:02 < nuxil> well. thanks, thats explains my problem. will need to add a extra instructions. was hopeing i could do my increment in one instuction.

2019-09-16T18:49:46 < englishman> hey pros question on interrupt preemption
2019-09-16T18:51:09 < englishman> if I enter an interrupt and clear its flag, then jump to a higher priority interrupt, if the same lower priority interrupt is fired while in the higher priority one, when the higher one returns, it will jump to the second lower priority interrupt due to tail-chaining, right?
2019-09-16T18:52:46 < mawk> yes that's the whole purpose of NVIC normally
2019-09-16T18:52:49 < mawk> to be able to nest interrupts
2019-09-16T18:53:04 < PaulFertser> englishman: and clear its flag in NVIC or are you talking about clearing the flag of a peripheral?
2019-09-16T18:55:13 < srk> can your cubemx start G0/G4 projects? I would like to see clock trees for these or at least know if they are similar to some of the Fxs

2019-09-16T18:57:17 < mawk> maybe if I update mine too
2019-09-16T18:57:28 < srk> it auto-updates the database but who knows
2019-09-16T18:58:51 < mawk> at least you can download G0 and G4 HAL

2019-09-16T19:00:35 < mawk> clock tree looks similar to what I've seen before

2019-09-16T19:02:37 < englishman> where A preempts B
2019-09-16T19:02:39 < mawk> ah you mean you clear the NVIC flag but before returning you get a new one ?
2019-09-16T19:02:57 < englishman> right, but it isn't in that routine, it's in the higher priority one

2019-09-16T19:04:05 < mawk> ah, then the first interrupt isn't finished yet then

2019-09-16T19:04:40 < PaulFertser> mawk: are you sure an ISR can nest itself in NVIC?
2019-09-16T19:04:45 < englishman> it does a1 b a2 a1, if the a interrupt fires during b
2019-09-16T19:05:15 < mawk> PaulFertser: I meant A1 will be finished normally, then A2 will fire, I didn't meant to say they are nested
2019-09-16T19:05:44 < mawk> ah by higher priority you mean higher number ?
2019-09-16T19:05:49 < mawk> aka lower "real" priority
2019-09-16T19:05:59 < englishman> lower value is higher priority

2019-09-16T19:06:33 < Cracki> kakimir, good stuff, that energy harvesting
2019-09-16T19:06:39 < PaulFertser> mawk: I think englishman is asking about about an ISR getting called for the same interrupt it's already servicing as a result of tail-chaining after getting preempted by a interrupt with more priority (and not in same subgroup).
2019-09-16T19:06:53 < englishman> right
2019-09-16T19:06:56 < mawk> yeah
2019-09-16T19:07:15 < PaulFertser> And an ISR can't preempt itself in any case ever, right?
2019-09-16T19:07:47 < PaulFertser> As any interrupt is in the same priority subgroup as itself.
2019-09-16T19:08:04 < englishman> according to pm0214, when the interrupt flag is cleared in software, the interrupt is changed from active back to inactive
2019-09-16T19:08:11 < Cracki> if you use the same code (ISR) for different interrupts, but that's silly
2019-09-16T19:08:15 < mawk> but you said you cleared the peripheral flag englishman no ?
2019-09-16T19:08:18 < mawk> [18:03:55] <englishman> hmm no, flag is cleared in periph
2019-09-16T19:08:21 < englishman> then the new interrupt a2 is marked pending when it fires again
2019-09-16T19:08:23 < srk> mawk: ok, now just need to figure out how I installed it on linux last time xD
2019-09-16T19:08:38 < mawk> you have a windows style installer in java srk 
2019-09-16T19:08:49 < mawk> you can install as non-root, it will get in your home dir
2019-09-16T19:09:39 < srk> yep, need to patchelf first
2019-09-16T19:09:59 < srk> my distro (nixos) doesn't have /lib64/ld-linux-x86-64.so.2 or similiar
2019-09-16T19:10:05 < mawk> ah, I see
2019-09-16T19:10:05 < englishman> PaulFertser: I'm not sure that applies, because when the a2 interrupt fires, the nvic is servicing b. due to tail-chaining, the a2 interrupt is serviced immediately
2019-09-16T19:10:07 < srk> not even /lib or /lib64 :D
2019-09-16T19:10:12 < mawk> but it's pure java
2019-09-16T19:10:20 < PaulFertser> Cracki: you're correct, indeed, ISR is the code and it can be shared (and there's actually shared code for all unhandled exceptions by default in libopencm3 iirc).
2019-09-16T19:10:31 < mawk> ah no not pure java you're right
2019-09-16T19:10:48 < englishman> then a1 finishes normally when the stack is popped
2019-09-16T19:11:26 < srk> mawk: think I'll just use an extractor which can extract javapack instead of installer

2019-09-16T19:14:02 < mawk> but you have stuff to do after the higher priority call that clears the NVIC flag in the A1 englishman ?
2019-09-16T19:14:24 < mawk> why is it bad that A1 doesn't come back right after the higher priority call
2019-09-16T19:14:44 < PaulFertser> englishman: https://developer.arm.com/docs/103489917/latest/how-to-implement-a-re-entrant-interrupt-within-the-cortex-m-exception-model
2019-09-16T19:14:50 < PaulFertser> It says it can never preemt itself.
2019-09-16T19:15:19 < srk> mawk: got it, you can rm it

2019-09-16T19:16:39 < englishman> PaulFertser: I'm still not sure that applies tho, because of the case when the interrupt fires when in a higher priority interrupt
2019-09-16T19:17:00 < englishman> it's more to do with interrupt chaining than reentrancy I think
2019-09-16T19:17:09 < PaulFertser> englishman: I'd bet on tail-chaining not being able to break those assumptions :)
2019-09-16T19:17:28 < srk> heh, except they've changed that as well /o\
2019-09-16T19:17:31 < PaulFertser> Or they would implement some trick based on that.
2019-09-16T19:17:37 < englishman> I'd hope So, anyway ,iam chasing bugs in old code and this appeared as a possibility
2019-09-16T19:18:20 < englishman> I don't see how the tail-chaining algo could know about the existing interrupt
2019-09-16T19:18:55 < mawk> the page says that if B were a lower priority than A then A would get preempted by itself, aka reentrancy
2019-09-16T19:19:01 < mawk> but your B is higher priority
2019-09-16T19:19:10 < englishman> right
2019-09-16T19:19:21 < PaulFertser> englishman: I'd guess there is some shadow pending bits register or something like that.
2019-09-16T19:19:53 < PaulFertser> Or shadow running ISR register
2019-09-16T19:20:14 < englishman> that implies a shadow stack doesn't it?

2019-09-16T19:22:12 < roomba> the weird pathnames and stuff just seem like insanity
2019-09-16T19:22:13 < mawk> it versions everything to prevent dependancy clash by design
2019-09-16T19:22:18 < srk> yep
2019-09-16T19:22:19 < mawk> it's a nice idea
2019-09-16T19:22:48 < PaulFertser> englishman: I'm not sure I follow, I hope others here are smarter wrt interrupts than me. But I'd guess there's just a register which has bits for currently running interrupts, I see no need for stack.
2019-09-16T19:22:50 < mawk> not even by version, by build ID, so even if two programs require a same version but with different ./configure flags it will work
2019-09-16T19:23:19 < srk> roomba: the issue ppl hit quite often is when you need to run bin from teh internetz but it points to /lib/ld-linux .., ad-hoc patchelf like this and it works
2019-09-16T19:23:24 < englishman> I'd like that to be correct,but I don't see anything in the programming manual that would lead me to believe that
2019-09-16T19:23:42 < roomba> snaps will rule us all soon

2019-09-16T19:25:56 < mawk> lol ARM docs trashing stm32: NOTE: Some third-party code libraries (e.g., the STM32 driver library) change the priority grouping configuration to non-standard. Therefore, it is highly recommended to explicitly re-set the priority grouping to the default by calling the CMSIS function NVIC_SetPriorityGrouping(0U) after initializing such external libraries.
2019-09-16T19:26:05 < englishman> I really think it just pushes the a1 interrupt on the stack then tailchains a2
2019-09-16T19:26:38 < mawk> you can verify that probably
2019-09-16T19:26:56 < mawk> push some timestamps into a stack
2019-09-16T19:29:53 < mawk> ah but it's difficult to provoke
2019-09-16T19:29:56 < englishman> yeah, the pm says the interrupt is marked as inactive when the flag is cleared
2019-09-16T19:30:04 < englishman> so there is a marking scheme,and it is cleared
2019-09-16T19:30:12 < mawk> just set A as pending in B, and see which of A1 and A2 runs first

2019-09-16T21:01:05 < grummund> do you know if the timer is running?
2019-09-16T21:01:23 < Lux> yeah it's running, the input capture events work
2019-09-16T21:03:11 < grummund> and the capture values are plausible for the intended timer frequency?
2019-09-16T21:04:24 < grummund> https://stackoverflow.com/questions/45702430/stm32-timer-interrupts
2019-09-16T21:05:46 < Lux> yeah all that works
2019-09-16T21:05:55 < grummund> you do HAL_NVIC_EnableIRQ(...) as well, right?
2019-09-16T21:06:11 < Lux> i get correct frequency values, just the part with detecting overflows is bugging me

2019-09-16T22:26:33 < Cracki> transmit data?
2019-09-16T22:26:42 < machinehum> 2G coverage might be available... however I'm not sure if the tech will work. Device has to be ~ 27mm dia x 9mm
2019-09-16T22:26:51 < Cracki> still, what data?
2019-09-16T22:27:06 < machinehum> Yeah so there will be an RTC that wakes the device up for a certain time of day
2019-09-16T22:27:21 < machinehum> If there is data, then you have located that tag
2019-09-16T22:27:24 < Lux> yeah for that size you probably won't find a module
2019-09-16T22:27:26 < Cracki> no, what data

2019-09-16T22:27:46 < machinehum> Some simple temp data and things, ook transmission scheme to keep it narrow band

2019-09-16T22:28:07 < machinehum> I'm talking about a couple bytes
2019-09-16T22:28:20 < machinehum> Cracki: it wouldn't require the drone
2019-09-16T22:28:22 < Cracki> just broadcast that in regular intervals
2019-09-16T22:28:32 < Cracki> drone, expensive
2019-09-16T22:28:38 < Cracki> just mount some receivers
2019-09-16T22:29:10 < machinehum> The existing solution gets 1000m on a good day, coverage area is too large
2019-09-16T22:29:34 < machinehum> To mount that many base stations
2019-09-16T22:29:47 < Cracki> so instead you want one station that flies?
2019-09-16T22:29:51 < machinehum> Yes
2019-09-16T22:29:59 < machinehum> Is that absurd?
2019-09-16T22:30:07 < Cracki> and you only care about receiving something inside the drone's radius?
2019-09-16T22:30:26 < machinehum> Yes
2019-09-16T22:31:11 < machinehum> I want to do some simple things to understand distance from the drone, doesn't have to be very precise
2019-09-16T22:31:12 < Cracki> and only for 10-30 minutes at a time, which is the battery life of the drone?
2019-09-16T22:32:02 < machinehum> We can put big batteries on the drone, say it flies around for 8hrs/day. Then chills to charge up.
2019-09-16T22:32:21 < Cracki> is it a quadrotor drone or a winged one
2019-09-16T22:32:29 < machinehum> Fixed wing
2019-09-16T22:32:36 < machinehum> Quad would not be able to do that
2019-09-16T22:32:39 < machinehum> I don't think
2019-09-16T22:32:57 < Cracki> right, that's why I asked for clarification
2019-09-16T22:34:03 < Cracki> and you think the cost of building and operating a drone would be competitive compared to putting up a dozen or however many stations?

2019-09-17T01:38:03 < aandrew> sector 5 is 128k which is large enough for a custom bootloader with ethernet support
2019-09-17T01:38:09 < aandrew> sorry sector 4
2019-09-17T01:38:16 < aandrew> and 5-7 are 256k each which is for the main application
2019-09-17T01:38:27 < aandrew> this is an F756
2019-09-17T01:38:32 < mawk> ah I see
2019-09-17T01:39:01 < aandrew> I could have put a tiny bootloader in sector 0 so I didn't have to change this but that rubbed me the wrong way to have a bootloader select between the main app and the loader/upgrader app
2019-09-17T01:39:42 < mawk> and you have dual bank for the main app ?
2019-09-17T01:39:48 < mawk> so that if upgrading fails the board isn't bricked
2019-09-17T01:39:50 < aandrew> no
2019-09-17T01:39:54 < mawk> ah
2019-09-17T01:39:55 < aandrew> the loader app is never updated
2019-09-17T01:40:02 < mawk> yeah not the loader, the main app
2019-09-17T01:40:12 < mawk> if the main app is corrupted because of power loss during upgrading
2019-09-17T01:40:13 < aandrew> so if flashing fails, the loader won't be able to verify the main app and will not boot it
2019-09-17T01:40:16 < mawk> yeah
2019-09-17T01:40:25 < aandrew> or, if IWDG reboots it a few times, it'll say something's wrong iwth the main app and refuse to boot it
2019-09-17T01:40:38 < mawk> ah, so that's normal
2019-09-17T01:40:42 < aandrew> yep
2019-09-17T01:40:45 < mawk> you plan for potential upgrade fails
2019-09-17T01:40:56 < aandrew> yep, been doing this too long to be optimistic :-)
2019-09-17T01:45:47 < mawk> you could have a compressed read-only version of the main app
2019-09-17T01:45:52 < mawk> to restore if the current one is messed up
2019-09-17T01:45:59 < mawk> even if it's an old version
2019-09-17T01:57:11 < aandrew> yes, but there's no real benefit to that over this I don't think
2019-09-17T01:57:27 < aandrew> the main app doesn't need to know tftp where this does

2019-09-17T05:43:51 < Cracki> when you touch his cursed bones, wear black rubber gloves like louis rossmann does
2019-09-17T05:44:48 < Cracki> kakimir, I'd use less/more, but simultaneously watch ram usage. if they're smart they memmap files.
2019-09-17T05:45:44 < Cracki> as for file appending, I'm sure there's a posixy way to use dd and /dev/zero to append exactly what you want
2019-09-17T05:46:43 < Cracki> I'd need docs for that, but not for doing it with python, so I'd use python
2019-09-17T05:47:34 < mawk> lol
2019-09-17T05:48:15 < mawk> what do you mean use dd and /dev/zero ?
2019-09-17T05:48:25 < mawk> ah
2019-09-17T05:48:31 < mawk> the best way is to add fake zeroes, kakimir 
2019-09-17T05:48:45 < mawk> use blocks of zeroes on the hdd/ssd, but not append real zeroes
2019-09-17T05:48:59 < mawk> the apparent file size will be that of what you want, but the real file size on disk is negligible
2019-09-17T05:49:10 < mawk> plus it's way easier to do that than to use dd and /dev/zero
2019-09-17T05:49:18 < mawk> it's ftruncate()
2019-09-17T05:49:30 < mawk> or truncate in bash
2019-09-17T05:50:03 < mawk> or in python, os.ftruncate(fd, size) or os.ftruncate(file.fileno(), size)

2019-09-17T08:35:46 < aandrew> .W is word, so 32 bytes?
2019-09-17T08:36:22 < Cracki> bits of course
2019-09-17T08:36:22 < turnip420> Isn't a word processor dependent or some shit

2019-09-17T08:36:27 < aandrew> er yes bits
2019-09-17T08:36:43 < Cracki> on cortex m there's no option, it's 32 bit
2019-09-17T08:36:45 < aandrew> so the value of R2 before this instruction is unimportant
2019-09-17T08:36:48 < turnip420> Like it's an 8bit mcu a word is 8 bits
2019-09-17T08:36:53 < Cracki> unless you mean they came up with 16 bit cortex m, or 64 bit cortex m
2019-09-17T08:37:05 < Cracki> even then they'll stick with 32 bits as a "word"
2019-09-17T08:37:23 < turnip420> 8 bit cortex m bro
2019-09-17T08:37:27 < Cracki> yes, R2 seems irrelevant, I'd think so
2019-09-17T08:37:29 < aandrew> R4 = 0x20010f18, so I need to look 0x31 bytes after 0x20010f18 or the dword at 0x20010f49?
2019-09-17T08:37:35 < aandrew> that shit's unaligned
2019-09-17T08:37:43 < Cracki> unless I have a brainfart and the direction of data is the other way
2019-09-17T08:38:15 < Cracki> it indeed looks unaligned
2019-09-17T08:38:34 < Cracki> unless that's doing C-style pointer arith and advancing 0x31 _words_
2019-09-17T08:38:58 < aandrew> now is it reading the address at 0x20010f49 and storing whatever is there into R2, or is it looking at the address stored at 0x20010f49 and putting the contents of *that* into R2?
2019-09-17T08:39:00 < Cracki> (have no assembly ref in front of me and never used cortex ma ssembly before :P)
2019-09-17T08:39:51 < aandrew> the value at 0x20010f48 is 0x00000006
2019-09-17T08:40:02 < aandrew> and whatever is at *address* 6 will generate a fault because I've got the MPU enabled
2019-09-17T08:40:06 < aandrew> and that's in fact what is happenning
2019-09-17T08:40:09 < Cracki> uh
2019-09-17T08:40:43 < Cracki> 3.4.2, str immediate offset?
2019-09-17T08:41:04 < Cracki> http://infocenter.arm.com/help/topic/com.arm.doc.dui0553b/DUI0553.pdf
2019-09-17T08:41:28 < aandrew> yeah, I'm at the non-pdf of that I think
2019-09-17T08:41:35 < aandrew> http://infocenter.arm.com/help/topic/com.arm.doc.dui0552a/BABJGHFJ.html
2019-09-17T08:41:56 < Cracki> I'd say it's reading the address computed by the [], not derefing it
2019-09-17T08:42:26 < aandrew> that form ([Rn, #offset]) is pre-indexed
2019-09-17T08:42:54 < Cracki> is it?
2019-09-17T08:43:00 < Cracki> pre-indexing uses !
2019-09-17T08:43:06 < Cracki> you do the normal thing
2019-09-17T08:43:07 < aandrew> op{type}{cond} Rt, [Rn, #offset]!          ; pre-indexed
2019-09-17T08:43:11 < aandrew> oh I didn't see !
2019-09-17T08:43:15 < aandrew> ok, it's immediate offset
2019-09-17T08:43:48 < Cracki> either way the address would be the same, the ! just changes (?) the register
2019-09-17T08:43:49 < aandrew> The offset value is added to or subtracted from the address obtained from the register Rn. The result is used as the address for the memory access.
2019-09-17T08:44:26 < Cracki> so R2 = *(R4 + 0x31)
2019-09-17T08:44:33 < aandrew> so it is a deref
2019-09-17T08:44:45 < Cracki> sure, it fetches the data from ram
2019-09-17T08:44:49 < Cracki> it's not a double deref
2019-09-17T08:44:53 < aandrew> and I'm getting a hardfault because I enabled the MPU to protect the memory around 0x000000
2019-09-17T08:45:01 < aandrew> hm
2019-09-17T08:45:03 < Cracki> R2 = R4 + 0x31 // would be ordinary math, not load/store
2019-09-17T08:45:16 < Cracki> wait
2019-09-17T08:45:18 < Cracki> what's R4?
2019-09-17T08:45:22 < Cracki> something that's not 6, yes?
2019-09-17T08:45:26 < aandrew> R4 is 0x20010f18
2019-09-17T08:45:34 < aandrew> which is DTCMRAM
2019-09-17T08:45:37 < Cracki> then it reads from 0x20...f18+0x31
2019-09-17T08:45:53 < Cracki> you said it, unaligned. that's probably the problem.
2019-09-17T08:46:04 < aandrew> 20010f48 is 0x00000006 and 0x20010f4c is 0x000000
2019-09-17T08:46:18 < Cracki> then R2 ends up 0x06 I'd say
2019-09-17T08:46:25 < Cracki> or something shifted like that
2019-09-17T08:46:30 < Cracki> of it hardfaults :P
2019-09-17T08:47:06 < Cracki> if this is coming from the mpu, maybe something *earlier or later* does the deref
2019-09-17T08:47:44 < aandrew> before that insn R4=0x20010f18. 0x20010f48=0x00000006/0x00000000
2019-09-17T08:47:46 < Cracki> are you sure you interpreted the program counter right
2019-09-17T08:47:50 < aandrew> if I execute the insn...
2019-09-17T08:48:03 < aandrew> kaboom
2019-09-17T08:48:15 < Cracki> my bet is on unaligned hf
2019-09-17T08:48:21 < Cracki> are you sure it's the mpu?
2019-09-17T08:48:32 < aandrew> no
2019-09-17T08:48:38 < Cracki> disable mpu?
2019-09-17T08:48:39 < aandrew> I would have expected a memmanage fault
2019-09-17T08:49:01 < aandrew> I unroll the stack frame in a hardfault
2019-09-17T08:49:10 < aandrew> PC=0x22288a which is that insn
2019-09-17T08:49:19 < aandrew> gotta look up what R0/R3 is
2019-09-17T08:49:35 < Cracki> oh wait you do a store, so the first argument is stored to ram!
2019-09-17T08:49:43 < Cracki> so so *(R4+0x31) = R2
2019-09-17T08:49:59 < Cracki> maybe change R4 before the store so the address is aligned
2019-09-17T08:50:03 < aandrew> hm
2019-09-17T08:50:06 < aandrew> let me try that
2019-09-17T08:50:26 < aandrew> that offset is fucked, 
2019-09-17T08:50:37 < aandrew> er wait
2019-09-17T08:50:50 < aandrew> no, R4 is 0x20010f18, which is aligned. it's the offset (0x31) which is fucked
2019-09-17T08:51:04 < aandrew> let me change R4 to 0x20010f17 to make the sum aligned
2019-09-17T08:51:27 < Cracki> maybe, or maybe it's assuming the R4 value is off and the arith would give an aligned addr
2019-09-17T08:51:30 < Cracki> yes
2019-09-17T08:51:31 < aandrew> yep you are absolutely right, its an unaligned access
2019-09-17T08:51:46 < Cracki> yay I got something right by never having done it :>
2019-09-17T08:51:59 < aandrew> change R4 to 20010f17, that plus 0x31 is 0x48 which is aligned and what was in R2 is now at 0x20010f48
2019-09-17T08:52:10 < Cracki> you had the alignment idea, all praise to you
2019-09-17T08:52:17 < aandrew> so now the question is why the fuck is that unaligned
2019-09-17T08:52:34 < Cracki> is that compiler generated code?
2019-09-17T08:52:41 < aandrew> yeah
2019-09-17T08:52:51 < aandrew> it's code copied from something that works on the same proc
2019-09-17T08:53:12 < Cracki> uh, assembly copied, or C/C++ copied?
2019-09-17T08:53:15 < aandrew> masically it's memcpy(netif->hwaddr, heth.Init.MACAddr, ETH_HWADDR_LEN), and netif->hwaddr is being unaligned
2019-09-17T08:53:45 < Cracki> then something calculated the R4 wrong
2019-09-17T08:53:54 < aandrew> yeah
2019-09-17T08:54:09 < Cracki> or the old code ran on something that tolerated unaligned access?
2019-09-17T08:54:20 < aandrew> nope exact same proc
2019-09-17T08:54:22 < Cracki> I think i read somewhere, unaligned may be allowed but behaves funky
2019-09-17T08:54:24 < Cracki> oh
2019-09-17T08:54:28 < aandrew> so it's something I've fucked up 
2019-09-17T08:55:56 < Cracki> netif->hwaddr and heth.Init.MACAddr are arrays I take it?
2019-09-17T08:56:04 < aandrew> yes
2019-09-17T08:56:20 < aandrew> it looks like netif->hwaddr is the unaligned one
2019-09-17T08:56:35 < Cracki> packed?
2019-09-17T08:56:45 < aandrew> nope... netif->hwaddr is at 0x20010f48 which is aligned
2019-09-17T08:56:51 < Cracki> o.o
2019-09-17T08:56:51 < aandrew> weird.
2019-09-17T08:57:27 < Cracki> where does the offset 0x31 come from then, if it's getting the addresses themselves
2019-09-17T08:58:11 < aandrew> that is a good question
2019-09-17T09:01:13 < Cracki> R4 is DTCMRAM you said... the beginning of the whole, or the beginning of the address you care about?
2019-09-17T09:01:34 < aandrew> well DTCMRAM starts at 0x200000
2019-09-17T09:01:39 < Cracki> ic
2019-09-17T09:01:45 < aandrew> there are eight packet buffers there
2019-09-17T09:01:49 < aandrew> but heth should not be in DTCMRAM
2019-09-17T09:01:57 < aandrew> netif netiher
2019-09-17T09:02:11 < aandrew> 0x2001... that might be outside of DTCMRAM
2019-09-17T09:02:40 < Cracki> compilers can have bugs. maybe the compiler assumes unaligned is allowed and behaves funky, rather than hardfaulting.
2019-09-17T09:03:04 < Cracki> I'm not sure it was cortex m but somewhere unaligned funky behavior was used to byte-swap data
2019-09-17T09:03:22 < Cracki> any way to permit unaligned access?
2019-09-17T09:03:36 < aandrew> yeah that's not in DTCM
2019-09-17T09:03:38 < aandrew> DTCM is only 64k
2019-09-17T09:03:46 < Cracki> "basically it's memcpy" but there's a little more to it
2019-09-17T09:03:58 < aandrew> but this same code works on another stm32f756 with the same compiler
2019-09-17T09:04:20 < Cracki> do you have that handy to step through and compare?
2019-09-17T09:04:51 < aandrew> interestingly
2019-09-17T09:05:00 < aandrew> netif is at 0x20010f17 <-- unaligned
2019-09-17T09:05:05 < Cracki> wat
2019-09-17T09:06:30 < aandrew> netif->hwaddr is 0x20010f48, but netif itself starts at an unaligned address
2019-09-17T09:06:30 < Cracki> offsetof(netif, hwaddr) is 0x31 maybe?
2019-09-17T09:06:30 < Cracki> lol
2019-09-17T09:06:30 < aandrew> yes I bet ist is
2019-09-17T09:06:30 < Cracki> howww
2019-09-17T09:06:30 < aandrew> well I was fucking with the linker script
2019-09-17T09:06:30 < aandrew> I bet I fucked it up
2019-09-17T09:06:30 < Cracki> indeed the difference is 0x31
2019-09-17T09:06:30 < Cracki> fascinating
2019-09-17T09:07:11 < Cracki> so something rounded R4 from ...f17 to f18, and THEN the store that would be aligned, isn't anymore
2019-09-17T09:07:23 < aandrew> https://pastebin.com/UMXMcPF3
2019-09-17T09:07:32 < Cracki> or no rounding but other bug
2019-09-17T09:07:48 < aandrew> that looks like it should be aligned
2019-09-17T09:09:02 < Cracki> alignment is ensured in line 2 and 11, but in between it might get fucky
2019-09-17T09:09:19 < Cracki> .bss and COMMON, anything weird in there?
2019-09-17T09:09:44 < Cracki> not common, that would only be affected, not affect
2019-09-17T09:11:02 < aandrew> hm, this area of the linker script looks identical to the one that works fine
2019-09-17T09:11:22 < Cracki> get a map of all the data and placement?

2019-09-17T09:13:18 < aandrew> no wait
2019-09-17T09:13:21 < aandrew> that is heth not netif
2019-09-17T09:13:23 < aandrew> netif is on the stack though
2019-09-17T09:13:35 < Cracki> something fucks the stack?
2019-09-17T09:14:01 < aandrew> netif is gnetif
2019-09-17T09:14:11 < aandrew> and that's initialize
2019-09-17T09:14:17 < aandrew> let's see where that is
2019-09-17T09:14:29 < aandrew>  .bss.gnetif    0x0000000020010f18       0x3c obj/lwip.o
2019-09-17T09:14:32 < aandrew> that's aligned
2019-09-17T09:14:55 < aandrew> the debugger's claiming that's 20010f17 though
2019-09-17T09:16:54 < aandrew> oh this is interesting
2019-09-17T09:16:56 < Cracki> step "backwards" mentally or restart? R4 got that value from somewhere
2019-09-17T09:17:08 < aandrew> I break much earlier where I'm passing netif in and it's correct
2019-09-17T09:17:13 < Cracki> !
2019-09-17T09:19:38 < aandrew> wtf
2019-09-17T09:19:57 < aandrew> oh
2019-09-17T09:20:01 < aandrew> no remember I moved it back one byte
2019-09-17T09:20:18 < Cracki> you did?
2019-09-17T09:20:29 < aandrew> yes to see if it was the unaligned access that was doing it
2019-09-17T09:21:28 < Cracki> so the 0x31 _is_ wrong?

2019-09-17T09:21:44 < aandrew> although gcc ought to be aligning struct elements

2019-09-17T09:22:30 < Cracki> but if R4 _is_ aligned, and the struct i aligned (or is it packed?), then 0x31 shouldn't be what the compiler computes
2019-09-17T09:22:56 < Cracki> *struct members aligned or packed
2019-09-17T09:23:09 < aandrew> that's what 'm saying it should be aligned
2019-09-17T09:23:13 < aandrew> there's no reason to pack it
2019-09-17T09:23:58 < Cracki> I'm unaware of ways to make C pack by default, I only know the packed attribute... but there might be a pragma somewhere, who knows
2019-09-17T09:24:13 < Cracki> #pragma pack applies to every structure definition placed after where it is inserted
2019-09-17T09:24:28 < Cracki> quote from stackoverflow
2019-09-17T09:24:35 < aandrew> yeah
2019-09-17T09:24:43 < aandrew> this is buried in hal though
2019-09-17T09:24:56 < Cracki> put a #pragma pack 4 and see if that fixes things?
2019-09-17T09:25:24 < aandrew> I am using -Os here and -Og in the working code

2019-09-17T09:27:22 < Cracki> almost same experience as watching a livestream of louis cursing over a defiled macbook
2019-09-17T09:27:40 < aandrew> it's hwaddr_len before it
2019-09-17T09:27:55 < aandrew> hwaddr_len is 0x20010f48 and hwaddr is 0x20010f49
2019-09-17T09:28:01 < aandrew> so what the fuck is packing it
2019-09-17T09:28:29 < Cracki> and why the fuck is gcc not noticing that it's generating unaligned accesses
2019-09-17T09:28:51 < Cracki> or that it shouldn't because you disallowed that... maybe it does assume that unaligned is allowed

2019-09-17T09:30:10 < Cracki> try permitting it, or tell gcc somehow that it mustn't generate those
2019-09-17T09:30:48 < Cracki> Os might be doing this... and gcc thinks it's ok to misalign because that's default
2019-09-17T09:33:11 < Cracki> can't find indication whether -Os would pack or not. time to experiment :)
2019-09-17T09:34:10 < Cracki> -mno-unaligned-access for a hotfix?

2019-09-17T11:00:13 < Ecco> yeah :-)
2019-09-17T11:00:42 < Ecco> So the power consumption is flat across the acceptable voltage, is that correct?
2019-09-17T11:00:45 < Ecco> sorry
2019-09-17T11:00:47 < Cracki> what operating voltage range are you faced with
2019-09-17T11:00:47 < Ecco> the current drawn
2019-09-17T11:01:03 < Ecco> I'm considering feeding an STM32 with a solar cell
2019-09-17T11:01:07 < Ecco> straight off the cell
2019-09-17T11:01:08 < Cracki> I'd expect it to be "flat enough" but if you look closely it will probably show some trend
2019-09-17T11:01:13 < Ecco> ok
2019-09-17T11:01:28 < ThatDamnRanga> You'll still need to regulate the cell
2019-09-17T11:01:32 < Cracki> current draw depends on whether it's doing anything of course
2019-09-17T11:01:44 < Ecco> Cracki: yes, sure.
2019-09-17T11:01:50 < Cracki> what peripherals are running, and actively doing things
2019-09-17T11:01:51 < ThatDamnRanga> if it is capable of producing more power than the STM draws, the voltage will run off into dangerous levels
2019-09-17T11:02:00 < Cracki> diode
2019-09-17T11:02:16 < Ecco> ThatDamnRanga: Indeed. Well, cells have a max voltage above which currents falls to zero
2019-09-17T11:02:30 < Cracki> yeah maybe grab an appropriate IC that buffers and converts
2019-09-17T11:04:27 < Cracki> this uses aidsfruit's solar charging board https://www.instructables.com/lesson/Solar-Powering-Microcontroller-Projects/
2019-09-17T11:04:38 < Cracki> the ic is a place to start
2019-09-17T11:05:37 < Cracki> >MCP73871
2019-09-17T11:06:18 < Cracki> or are you going for one of those tiny cells in solar powered calculators?
2019-09-17T11:07:47 < jpa-> Ecco: for most digital chips, current consumption is linearly proportional to voltage - because most of the consumption is charging and discharging parasitic capacitances
2019-09-17T11:07:53 < Cracki> watch the open circuit voltage
2019-09-17T11:09:51 -!- learningc [~learningc@mti-37-145.tm.net.my] has joined ##stm32
2019-09-17T11:10:16 < Ecco> Cracki: yeah, I'm just trying to power the STM32 itself
2019-09-17T11:10:39 < Ecco> since little power shall be needed, I was hoping to find a solution without any extra IC
2019-09-17T11:10:53 < Cracki> I think if you dimension it all right, you could operate near the open circuit voltage with variable current draw, so long as it's little enough to maintain a usable voltage
2019-09-17T11:11:07 < Cracki> just staring at this curve here http://www.alternative-energy-tutorials.com/energy-articles/solar-cell-i-v-characteristic.html
2019-09-17T11:12:03 < jpa-> Ecco: e.g. STM32F407 datasheet gives RUN@120MHz 1.8V: 24.7mA, 3.3V: 38mA; 38/24.7 = 1.5, 3.3/1.8 = 1.8
2019-09-17T11:12:38 < Ecco> oh, interesting
2019-09-17T11:12:44 < Ecco> ok, so it's not flat indeed
2019-09-17T11:12:51 < Ecco> it's not super steep either
2019-09-17T11:14:33 < aandrew> hm, interesting. the MPU as I've configured it does seem to fault on unaligned accesses
2019-09-17T11:16:31 < canton7> aandrew, I didn't catch the context, but... have you set UNALIGN_TRP in CCR?
2019-09-17T11:20:03 < aandrew> canton7: https://pastebin.com/xt2LPHQD is the function
2019-09-17T11:20:11 < aandrew> Just taking it apart now to see what the fuck I did again
2019-09-17T11:20:16 < aandrew> basically two overlapping regions
2019-09-17T11:20:28 < aandrew> region 0 = entire address space, full access with execute permission
2019-09-17T11:20:44 < aandrew> region 1 = 1kb @ 0x0 with no permission
2019-09-17T11:21:57 < canton7> aandrew, and what's your problem again? It's trapping on unaligned access?
2019-09-17T11:25:22 < aandrew> yeah
2019-09-17T11:25:51 < aandrew> it's odd though becasue I'm not seeing a way for the MPU to do that
2019-09-17T11:26:05 < canton7> aandrew, and you're sure that's to do with the MPU, and not because you set UNALIGN_TRP in CCR?
2019-09-17T11:28:03 < aandrew> I'm not aware that I've set that, let me check though, good idea
2019-09-17T11:28:15 < aandrew> with mpu_init() commented out, I don't get faults
2019-09-17T11:28:48 < Cracki> maybe the mpu inherently doesn't like unaligned
2019-09-17T11:28:57 < canton7> I'm using unaligned access just fine with the MPU set up
2019-09-17T11:29:00 < canton7> (on an M4)
2019-09-17T11:29:04 < Cracki> hm
2019-09-17T11:29:12 < aandrew> yeah me too when I don't call mpu_init() :-)
2019-09-17T11:29:23 < Cracki> anything in mpu_init that touches anything other than the mpu
2019-09-17T11:29:35 < canton7> aandrew, just covering all the bases: the fault that you get when you don't comment out mpu_init() - how do you know that's because of unaligned access?
2019-09-17T11:30:17 < aandrew> oh, because if I intentionally alter the instruction that causes the fault so that it does not generate an unaligned access, it doesn't fault
2019-09-17T11:30:35 < canton7> aandrew, right, so it's not because you're looking at the details of the fault?
2019-09-17T11:30:45 < aandrew> I don't think so, no
2019-09-17T11:30:51 < aandrew> basically break on the function that will fault
2019-09-17T11:30:54 < Cracki> you had an f7? with external ram? http://www.keil.com/support/docs/3777.htm
2019-09-17T11:30:57 < canton7> OK. I suggest you look at the details of the fault, and see why the hardware thinks the fault happens
2019-09-17T11:30:59 < aandrew> no external RAM
2019-09-17T11:31:04 < aandrew> yeah I was digging into that
2019-09-17T11:31:39 < aandrew> STR.W R2, [R4, #0x31]
2019-09-17T11:31:48 < aandrew> R4=0x20010f18
2019-09-17T11:32:06 < aandrew> so *(R4+0x31) = kaboom
2019-09-17T11:32:21 < aandrew> if I set R4 = 0x20010f17 and execute the same instruction, no problem
2019-09-17T11:32:23 < canton7> (look in CFSR / MMFAR))
2019-09-17T11:32:54 < Cracki> "device" regions want aligned access? https://community.st.com/s/question/0D50X00009q5OZnSAM/hardfault-on-unaligned-access-after-enabling-mpu
2019-09-17T11:33:06 < canton7> that does ring a bell, actually
2019-09-17T11:33:13 < aandrew> that might just be it, I set TEX=0 which is exactly that actually
2019-09-17T11:33:44 < aandrew> although only on region 1, but I see I'm not initializing the entire struct for region 0, a sin for which I'll self-flagellate later
2019-09-17T11:35:24 < Cracki> Ecco, I see 3v cells on aliex with enough milliamps. damn now I'm thinking of ordering one for toying
2019-09-17T11:36:22 < canton7> aandrew, the uninitialised members just get 0-initialised then - no need for flagellation
2019-09-17T11:36:30 < Ecco> Cracki: :-)
2019-09-17T11:37:01 < Cracki> I don't see any that are small enough for a pocket calculator. the 3v 120ma one is ~50x50mm
2019-09-17T11:37:30 < Ecco> Well, 120mA is a lot
2019-09-17T11:37:31 < Cracki> if you need stable voltage, LDO :P
2019-09-17T11:37:32 < aandrew> interesting:  I just stumbled across this: from the same L4/F3/F4 Cortex programmers manual, in the description of the CCR "UNALIGN_TRP" bit, the LDM, STM, LDRD and STRD will *always* fault on unaligned access regardless of the UNALIGN_TRP setting.
2019-09-17T11:37:47 < Cracki> TIL
2019-09-17T11:37:50 < Ecco> is that true on F7 too?
2019-09-17T11:37:55 < aandrew> yeah I am not sure I believe that
2019-09-17T11:38:50 < zyp> englishman, what interrupt theory?
2019-09-17T11:46:59 < aandrew> Cracki: that was it
2019-09-17T11:47:11 < aandrew> fixed the mpu bits soit wasn't seen as device memory and it works again
2019-09-17T11:47:59 < Cracki> til about what the mpu can affect that's more than simple protection :P
2019-09-17T11:48:32 < canton7> Nice one
2019-09-17T11:48:45 < aandrew> yep. TIL for me too
2019-09-17T11:48:48 < aandrew> thanks guys
2019-09-17T11:48:57 < canton7> I vaguely remember reading something about that when I was doing my MPU config, but it didn't apply to the core I was using so I didn't internalise it ><
2019-09-17T11:48:59 < aandrew> I think I got basic bootloadering working now
2019-09-17T11:49:11 < aandrew> test the fpga update mechanism tomorrow
2019-09-17T11:49:45 < canton7> The main gotcha I found was that MPU regions need to be aligned to their size. That little nugget is hidden away, but things go bad if you don't follow it
2019-09-17T11:49:48 < Cracki> >Unaligned LDM, STM, LDRD, and STRD instructions always fault irrespective of whether UNALIGN_TRP is set to 1.
2019-09-17T11:49:59 < Cracki> you had STR tho, so that's in line with what happened
2019-09-17T11:50:28 < Cracki> (Generic User Guide, 4.3.7)
2019-09-17T11:50:58 < Cracki> limitation makes sense, ldm is load multiple registers
2019-09-17T11:51:20 < Cracki> and STRD is two words
2019-09-17T11:52:16 < Cracki> iirc the bus is 64 bit so for any misaligned request of a single word it can fetch both and handle that, but not for multi-word situations
2019-09-17T11:53:16 < zyp> uh, wouldn't it still have a problem fetching across 64-bit boundaries?
2019-09-17T11:53:28 < Cracki> no because it fetches 64 bits aligned to 32 bits :P
2019-09-17T11:53:37 < zyp> does it?
2019-09-17T11:53:42 < Cracki> I think so
2019-09-17T11:54:16 < Cracki> might the that's why they even have a 64 bit bus
2019-09-17T11:54:31 < zyp> heh
2019-09-17T11:55:22 < Cracki> picking 32 bits out of a 64 bit read probably costs zero. there are only 1 aligned case + 3 cases of misalignment
2019-09-17T11:56:15 < Cracki> (I might be totally mistaken about the bus being 64 bit)
2019-09-17T11:57:25 < Cracki> cm4 trm says "32-bit AHB-Lite bus", oh well
2019-09-17T11:58:15 < Cracki> wow, downstairs stoner is lighting up again. he must have woken up just now. he last blazed it 10 hours ago
2019-09-17T11:58:39 < Cracki> aha! wikipedia claims that CM7 has 64 bit busses for instruction and data

2019-09-17T13:58:04 < PaulFertser> The actual substances are different, they just belong to the same class or whatever that's called.
2019-09-17T13:58:23 < englishman> zyp: i'm hunting down a weird bug in some old software. i think it's related to interrupt sequencing. i have two interrupts A and B, B is higher priority. A fires and the flag is cleared (in this case, spi rxne). As it is being serviced B fires. During B, A fires again. So when A returns, the second B interrupt is serviced instead of returning to the first, because the RXNE flag has been cleared, setting the
2019-09-17T13:58:24 < englishman> interrupt back to Inactive in the NVIC, and the NVIC does not touch the stack due to tailchaining. So the order of interrupts becomes A1 B A2 A1
2019-09-17T13:58:50 < englishman> So when A returns -> should read B
2019-09-17T13:59:00 < englishman> the second B interrupt -> A, fuk
2019-09-17T14:00:14 < PaulFertser> englishman: you told me you reset flag in nvic but today you're saying the flag is cleared in SPI peripheral.
2019-09-17T14:00:39 < englishman> yeah, just the rxne flag in spi, i thought i corrected myself yesterday, sorry
2019-09-17T14:01:05 < PaulFertser> np, I might have missed the correction
2019-09-17T14:01:25 < englishman> np
2019-09-17T14:01:54 < englishman> as far as i know that flag and the interrupt line going to the nvic are one and the same (once enabled) but i added it here for clarity
2019-09-17T14:03:18 < PaulFertser> englishman: were you able to somehow instrument the code to prove your tail-chaining theory? If the bug can be reliably reproduced you can set some global volatile bool to true when entering A and to false right before exiting and right before setting it at the beginning you can check if it's already set, in that case halt and wait for debugger?
2019-09-17T14:05:33 < englishman> i should know more today, all i had was a description of the problem and sores, not even hardware or a toolchain (iar)

2019-09-17T14:10:30 < Thorn> englishman: an interrupt should never preempt itself. does that software mess with priorities in realtime?

2019-09-17T14:21:43 < Thorn> >The processor tail-chains if a pending interrupt has higher priority than all stacked exceptions.
2019-09-17T14:21:47 < englishman> Thorn: I don't think it's related to preemption, because the A2 interrupt occurs in sequence after B returns, as expected. I think it's more related to how the nvic keeps track of existing interrupts. once the rxne flag is cleared, and the isr has been preempted by another isr, how does the nvic keep track of the isrs already on the stack? since tail-chaining exists, it doesn't check the stack to see if it
2019-09-17T14:21:48 < englishman> should return to an isr of the same priority. the rxne flag has cleared which I'm pretty sure marks the interrupt as inactive in the nvic. so what's to stop the nvic from chaining to a2 after B?
2019-09-17T14:22:14 < englishman> hmm, is that from the PM
2019-09-17T14:22:16 < Thorn> http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0337e/Babjagdg.html
2019-09-17T14:22:59 < englishman> see, I read that page too, and it's not exactly the same as what st has in the PM for f302
2019-09-17T14:23:26 < englishman> the m4 nvic is a little different, supporting pulse and level interrupts
2019-09-17T14:23:57 < englishman> plus it doesn't expand on how it keeps track of stacked interrupt priorities
2019-09-17T14:24:42 < Thorn> CURRPRI I guess
2019-09-17T14:24:58 < Thorn> it must be the highest of all stacked exceptions
2019-09-17T14:25:04 < englishman> right?!
2019-09-17T14:25:31 < englishman> anyway, the quick thing I told the guy to do is move the flag reset to the end of the isr
2019-09-17T14:25:49 < Thorn> then you can lose A2 (if it's caused by the same flag)
2019-09-17T14:25:57 < englishman> it is, yeah
2019-09-17T14:26:10 < englishman> and hmm yeah
2019-09-17T14:26:14 < englishman> you're right
2019-09-17T14:26:19 < Thorn> loss of an interrupt is probably just as bad

2019-09-17T15:53:17 < canton7> englishman, I don't think you'll get tail-chaining then? http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0337e/Babjagdg.html says "When returning from an exception, the processor is either ... returning to the last stacked ISR if there are no pending exceptions or if the highest priority stacked exception is of higher priority than
2019-09-17T15:53:18 < canton7> the highest priority pending exception" . But in your case, A1 is stacked and A2 is pending, so the processor will return to the last stacked ISR (A1). When A1 is completed, that condition *is* met, and it will tail-chain onto A2
2019-09-17T15:55:48 < mawk> got fired

2019-09-17T20:54:58 < grummund> is it possible to 'brick' a stm32f030 as in will no longer respond to SWD?
2019-09-17T20:59:30 < aandrew> grummund: check the RM to see if you can disable the swd interface (I don't think you can)
2019-09-17T20:59:43 < aandrew> there are read protections but I think they're all fully reversible
2019-09-17T21:02:18 < grummund> this happens with "Set all free pins as analog (to optimize the power consumption)" ticked in cubemx code generator

2019-09-17T21:17:24 < mawk> no it's not possible grummund 
2019-09-17T21:17:35 < mawk> you just have to wire up the physical NRST to your stlink
2019-09-17T21:17:40 < mawk> to force it in SWD mode
2019-09-17T21:17:45 < mawk> or use BOOT0 yes
2019-09-17T21:18:16 < grummund> ah yes i see
2019-09-17T21:18:16 < Steffanx> Do people actually use C11? I've never seen https://en.cppreference.com/w/c/language/generic in the wild for example.
2019-09-17T21:18:44 < mawk> all _Functions like this have lowercase equivalent in the libc normally Steffanx 
2019-09-17T21:18:50 < mawk> _Function is a notation for a C99/C11 builtin
2019-09-17T21:18:52 < mawk> for instance _Exit
2019-09-17T21:18:58 < mawk> but you use exit in practice
2019-09-17T21:19:43 < Steffanx> that's wnot what this page is about..
2019-09-17T21:20:05 < mawk> yeah but I mean if you see it in practice it won't be named _Generic probably
2019-09-17T21:20:17 < Steffanx> the wannabee generics in C11
2019-09-17T21:20:19 < mawk> I've seen the C99 equivalent using __typeof__ and stuff
2019-09-17T21:20:28 < mawk> I use them, often
2019-09-17T21:20:34 < PaulFertser> grummund: with SWD you can connect reset line and use srst_only connect_assert_srst with OpenOCD, then it'll always connect without BOOT0, regardless of flash contents.
2019-09-17T21:20:52 < grummund> yeah i have reset discinnected
2019-09-17T21:22:30 < Steffanx> nah, ive never seen this generic macro ever.
2019-09-17T21:22:40 < grummund> it's not routed through to the 'debug' connector on this little board
2019-09-17T21:23:01 < mawk> what about C17 Steffanx 
2019-09-17T21:23:01 < kakimir> hello evenings
2019-09-17T21:23:03 < grummund> there ought to be a C-- standard, with all the weird stuff removed.
2019-09-17T21:23:04 < mawk> you found cool stuff ?
2019-09-17T21:23:11 < mawk> why grummund ?
2019-09-17T21:23:17 < mawk> just use C++ with no standard lib if you want
2019-09-17T21:23:20 < mawk> no exceptions, no RTTI
2019-09-17T21:23:50 < grummund> so much of it is horse trading between the committee members... you approve my weird feature and i'll approve yours.
2019-09-17T21:23:57 < Steffanx> i never looked at C17 mawk
2019-09-17T21:24:09 < Steffanx> especially since ive not really seen people even use c11 in the wild
2019-09-17T21:24:50 < grummund> i've used the static assert feature
2019-09-17T21:24:57 < mawk> I use gnu99
2019-09-17T21:25:00 < Steffanx> except for that maybe.
2019-09-17T21:25:08 < mawk> I should try your generic thing
2019-09-17T21:25:10 < grummund> and i expect code to be C11 compliant
2019-09-17T21:25:32 < mawk> but I've already used __typeof__ for instance in macros to check return code whichever type they may be, and return that code if it's not < 0
2019-09-17T21:25:37 < qyx_> does msvc support c99 yet?
2019-09-17T21:25:39 < Steffanx> lolyou mawk. C17 doesnt even exist. C18 it is
2019-09-17T21:25:48 < mawk> they said C17 in your page :((
2019-09-17T21:25:53 < Steffanx> hah ok
2019-09-17T21:26:00 < mawk> « This was specified by the C17 DR 481 (which applies retroactively to C11). »
2019-09-17T21:26:15 < Steffanx> oh it does exist it seems
2019-09-17T21:26:46 < Steffanx> but even wikipedia redirects c17 to c18
2019-09-17T21:27:05 < Steffanx> ah " It has been informally named as C17 too. " 
2019-09-17T21:43:43 < englishman> maybe it's like altium versions, where they use odd years for beta versions and even years for versions that aren't total shit.

2019-09-17T22:49:36 < Steffanx> tldr; for sure
2019-09-17T22:49:57 < roomba> Steffanx: i'm trying to mitigate some risk of AI used by HR intelligence companies linking me to my sarcasm/satire/stupidity instead of having real human interaction to decide if i'm a good person or not. if that makes any sense.
2019-09-17T22:50:28 < roomba> so i became a vacuum cleaner
2019-09-17T22:51:02 < Steffanx> you have already been linked to your prev. nick by a few, roomba
2019-09-17T22:51:51 < Laurenceb_> the autism level makes it very clear who you are
2019-09-17T22:52:16 < roomba> a few humans
2019-09-17T22:52:30 < Steffanx> Does a autism-detector work like a gaydar? You have to be one to have it?
2019-09-17T22:52:31 < roomba> i'm banking on the AI not being able to pick up on it as quickly
2019-09-17T22:52:34 < Laurenceb_> only the nasaspaceflight crew could take ten years to fail to connect a microwave oven to a resonator
2019-09-17T23:03:17 < Steffanx> i do understand why you go crazy Laurenceb_. Working on the shaker for over 4 years non-stop..

2019-09-17T23:22:41 < Laurenceb_> her cunning plan was to stick a rpi with phone tethered to it inside the ceiling at police hq then haxor the police database
2019-09-17T23:22:57 < Laurenceb_> what could possibly go wrong
2019-09-17T23:23:22 < Cracki> she'd need to handle everything with gloves, and scrub it with alcohol to be sure

2019-09-17T23:23:39 < Laurenceb_> ikr

2019-09-17T23:48:04 < Laurenceb_> at least space runway makes physical sense

2019-09-17T23:51:28 < Laurenceb_> as the vehicle speed increases, the choked flow around the vehicle stays at mach 1, but guess what? The air is compressed so mass flow increases

2019-09-18T15:12:27 < rajkosto> stuff you would use on pcbs
2019-09-18T15:12:41 < rajkosto> i wanna smear it between a copper and aluminum plate and oven it

2019-09-18T15:55:06 < rajkosto> in that case i can add screw holes and make it out of acrylic
2019-09-18T15:55:18 < rajkosto> cheapest acrylic ?
2019-09-18T16:07:05 < nuxil> solder copper to aluminium? what kind of an alloy are you trying to make :p ?
2019-09-18T16:07:25 < rajkosto> i just have 2 plates i need to be stuck together
2019-09-18T16:08:09 < nuxil> solder pase will no solder them. but help with termal issues. better transfere of heat
2019-09-18T16:08:25 < rajkosto> if i just wanted that i could have used thermal paste
2019-09-18T16:08:42 < nuxil> yea.
2019-09-18T16:08:56 < rajkosto> do they still make "ceramique" gluing thermal paste 
2019-09-18T16:08:58 < rajkosto> maybe that would work
2019-09-18T16:09:12 < nuxil> super glue :p
2019-09-18T16:09:59 < nuxil> but yea. that might work. or just crew the plates together if possible.
2019-09-18T16:11:49 < rajkosto> that would require drilling
2019-09-18T16:13:16 < nuxil> but in teory. solder paste could work. if the surfaces are clean. and press them together when the solder is becoming liquid.  create a vacume between the plates. almost impossible to seperate them after
2019-09-18T16:15:02 < nuxil> using solder to binds stuff together has been used for 100years or so.

2019-09-18T16:50:41 < rajkosto> can you just screw through a hole in acrylic to "tap" it
2019-09-18T16:51:17 < Ultrasauce> it will probably crack if you dont use self tapping screws
2019-09-18T16:51:29 < rajkosto> whats the difference
2019-09-18T16:51:30 < nuxil> yea. acrullic crack easly.. 
2019-09-18T16:52:39 < Ultrasauce> they have a sharper thread profile and a slot down the length to collect the removed material
2019-09-18T16:57:00 < mawk> why doesn't solder work on aluminium ?
2019-09-18T16:57:59 < nuxil> what do you mean? solder works on aluminium. you can bind alu with steel, copper etc fine.
2019-09-18T17:02:01 < rajkosto> with just normal Sn/Pb solder paste ?
2019-09-18T17:07:10 < mawk> why did you say solder paste wouldn't work with copper and aluminium ?
2019-09-18T17:08:54 < nuxil> well my mistake then. i said you cant solder them together. aka make an alloy.  but you use the solder as a binding.
2019-09-18T17:09:06 < qyx> pecause alu is covered with oxides and stuff, you need flux for soldering aluminium!
2019-09-18T17:09:13 < mawk> ah, I see
2019-09-18T17:09:24 < qyx> fuk android kbd
2019-09-18T17:09:37 < qyx> some characters were added
2019-09-18T17:09:40 < nuxil> alot of flux is reccomended :)
2019-09-18T17:10:19 < mawk> android keyboard has π Δ ≈ ≠ and a bunch of other nice characters
2019-09-18T17:10:46 < nuxil> quick google search will give tonz of videos, examples and so on using all kind of solder and flux. 
2019-09-18T17:12:18 < nuxil> but as a sidenote. alu does not play well with other metals. 
2019-09-18T17:13:12 < englishman> android KB also has useless characters like € and é
2019-09-18T17:13:21 < Sadale> quick question. When I'm ordering a stencil, why's the valid area far, far smaller than the actual area?
2019-09-18T17:13:32 < englishman> you need a way to hold the stencil
2019-09-18T17:13:55 < englishman> you could always cut it down if you want
2019-09-18T17:14:09 < qyx> englishman: thats not pekné
2019-09-18T17:14:11 < englishman> but when you get them from China they are made for chinese stencil printers
2019-09-18T17:14:32 < Sadale> I'm ordering from jlcpcb.
2019-09-18T17:15:05 < englishman> and where are they located
2019-09-18T17:15:09 < Sadale> China.
2019-09-18T17:15:30 < Sadale> They allow me to customize my size. My boards is only 100mmx100mm when panalized. Using a 380*280 stencil (with 290*190 valid area) seems to be an over kill.
2019-09-18T17:15:35 < nuxil> isnt 90% of the pcb manufacturers in china :p ??
2019-09-18T17:15:38 < Sadale> https://jlcpcb.com/quote
2019-09-18T17:16:23 < nuxil> no western contry can compete with thouse low prices.
2019-09-18T17:17:15 < mawk> pekné
2019-09-18T17:17:38 < Sadale> I wonder if I should ask them to cut down the size of the stencil.
2019-09-18T17:17:55 < mawk> they most likely did it on purpose Sadale , they would've noticed by now if the stencils are all 3× too big
2019-09-18T17:17:56 < Sadale> wow. That English on the ordering page tho. "To save disappointment, please double check the instructions for ordering before you plance your order. "
2019-09-18T17:18:00 < mawk> since that's like 9× more matter
2019-09-18T17:18:08 < mawk> lol
2019-09-18T17:18:18 < Sadale> mawk, I see. But still, it's too big a piece to fit into my home :(
2019-09-18T17:18:35 < Sadale> It's 380 freaking mm!
2019-09-18T17:18:40 < Sadale> times 280 mm!
2019-09-18T17:18:46 < nuxil> lol
2019-09-18T17:19:44 < englishman> 290*190 stencil area is huge
2019-09-18T17:20:06 < englishman> do you have a 20cm squeegee
2019-09-18T17:20:08 < Sadale> I agree. That's the smallest one they have :(
2019-09-18T17:20:18 < Sadale> nope.
2019-09-18T17:20:33 < Sadale> My boards is only 100mm * 100mm after panalization.
2019-09-18T17:20:47 < englishman> that's the chinese stencil size I order cuz it fits in my chinese stencil printer
2019-09-18T17:21:26 < Sadale> I don't really have a stencil printer. I'm ordering stencil that's to be cut in the PCB fab.

2019-09-18T20:04:58 < PaulFertser> jpa-: hey :) I wonder if you have an opinion regarding englishman's idea of interrupts tail-chaining resulting in "re-entrancy" for a handler.
2019-09-18T20:09:20 < Steffanx> Now you just expect to much of a finnisher..
2019-09-18T20:10:13 < PaulFertser> I know jpa- has deep understanding of the Cortex-M exception model.
2019-09-18T20:16:34 < Steffanx> i wondered how englishman concluded he got  "a1 b a2 a1". Did mr englishman use fancy tracing to see that?
2019-09-18T20:16:58 < englishman> no
2019-09-18T20:17:07 < englishman> I dont even have hardware

2019-09-18T20:18:03 < englishman> even if it isn't that, now I'm curious
2019-09-18T20:18:28 < Steffanx> it cant be that hard to make a test case with a few interrupts

2019-09-18T20:19:35 < jpa-> PaulFertser: can you elaborate?
2019-09-18T20:20:36 < PaulFertser> jpa-: basically englishman thinks that a lower-priority isr a is running and then a higher-priority isr b happens, preempts a and while it's still processing a new a event happens and when b exits the a handler starts running from the start of the proc.
2019-09-18T20:21:04 < jpa-> englishman: to do tracing you just need to have PB3 pin free and have a logic analyzer or usb-usart converter; you can slow down the cpu so that even slow usart can catch the data
2019-09-18T20:21:39 < jpa-> PaulFertser: nah, the basepri register would prevent that, atleast unless interrupt priorities are changed while in interrupt
2019-09-18T20:22:22 < PaulFertser> englishman: jpa-'s tracing: http://essentialscrap.com/tips/arm_trace/
2019-09-18T20:26:19 < jpa-> http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0337e/Babjagdg.html   "The processor tail-chains if a pending interrupt has higher priority than all stacked exceptions."
2019-09-18T20:27:04 < jpa-> not sure if you could really get that situation by changing A into high priority during B interrupt, but at least without changing priority it shouldn't happen
2019-09-18T20:27:31 < PaulFertser> englishman: so get your hands on hardware and debug it properly ;)
2019-09-18T20:28:59 < Thorn> englishman: grep the code for all nvic fuckery
2019-09-18T20:29:18 < Thorn> any and all

2019-09-19T00:15:42 < DisruptiveNL_> Hi I have troubles making my RTOS work with the STM32F429ZI-DISC1. It was working on the STM32F429-DISCOVERY, but this board is not available anymore.

2019-09-19T00:29:42 < Cracki> if you make this like pulling teeth, it will be pulling teeth
2019-09-19T00:30:14 < roomba> RTOS doesn't work and the board isn't available anymore.
2019-09-19T00:30:19 < roomba> Cracki: just fix it ok?
2019-09-19T00:30:20 < DisruptiveNL_> Well the hex I have/had working on the stm32f429i-discovery does not work on the DISC1
2019-09-19T00:30:34 < Cracki> ¯\_(ツ)_/¯
2019-09-19T00:30:57 < DisruptiveNL_> And USART and other pheripherals are having strange behaviour
2019-09-19T00:31:16 < DisruptiveNL_> it ¨goes to idle¨ state but ¨hangs¨ the USART
2019-09-19T00:31:27 < Cracki> work the problem https://www.fastcompany.com/3031498/problem-solving-lessons-from-nasa
2019-09-19T00:32:00 < Cracki> is it the EXACT SAME IDENTICAL chip?
2019-09-19T00:32:26 < Cracki> I'm betting not
2019-09-19T00:33:27 < DisruptiveNL_> STM32F429I-DISC1 order code has replaced the old STM32F429I-DISCO order code.
2019-09-19T00:33:46 < DisruptiveNL_> STM32F429ZIT6 = DISC1
2019-09-19T00:34:30 < Cracki> k then if a binary doesn't work, take all the steps back, start from nothing, test each peripheral individually
2019-09-19T00:35:01 < DisruptiveNL_> https://www.st.com/content/ccc/resource/technical/document/user_manual/6b/25/05/23/a9/45/4d/6a/DM00093903.pdf/files/DM00093903.pdf/jcr:content/translations/en.DM00093903.pdf
2019-09-19T00:35:06 < DisruptiveNL_> Chip is the same?
2019-09-19T00:35:09 < Cracki> do the pcbs look identical?
2019-09-19T00:35:15 < DisruptiveNL_> Yes
2019-09-19T00:35:37 < Cracki> it's broken :>
2019-09-19T00:35:49 < DisruptiveNL_> Haha no the STM demo works

2019-09-19T00:40:30 < Cracki> thanks to these climate alarmists scaring the children shitless I have to plan my friday like it's doomsday
2019-09-19T00:40:52 < Cracki> children are so impressionable. they literally think (1) the world is gonna end (2) they can do shit about it
2019-09-19T00:41:23 < Cracki> DisruptiveNL_, looks like they upgrades the stink
2019-09-19T00:41:45 < Cracki> so it's a good bet that they changed more
2019-09-19T00:42:03 < roomba> yep and maybe even the board layout. traces.
2019-09-19T00:43:06 < Cracki> so far that's all they admit to in that "data brief"
2019-09-19T00:43:14 < Cracki> it's not a "data shit"

2019-09-19T00:51:12 < Cracki> check all fiddly bits
2019-09-19T00:51:20 < Cracki> check all bits you need to circumcise
2019-09-19T00:51:32 < Cracki> check all bits you need to sew shut
2019-09-19T00:51:53 < Cracki> i.e. traces to cut, bridges to solder
2019-09-19T00:52:13 < DisruptiveNL_> realllyyy 
2019-09-19T00:52:17 < Cracki> recompile, try different clock config, maybe it's marginal
2019-09-19T00:52:46 < Cracki> desolder all components, backlight-scan both the board's sides, digitize the copper layers
2019-09-19T00:53:00 < DisruptiveNL_> your link is the same and no Reference sheet
2019-09-19T00:53:06 < DisruptiveNL_> only user manual stuff
2019-09-19T00:53:13 < Cracki> yes, that's all you're gonna get
2019-09-19T00:53:43 < DisruptiveNL_> ....
2019-09-19T00:53:44 < Cracki> you're supposed to investigate the board yourself, no cheatsheet :P
2019-09-19T00:54:06 < DisruptiveNL_> Oww why does NXP sounds really good right now :P
2019-09-19T00:54:09 < Thorn> DisruptiveNL_: use a debugger, find where your firmware crashes
2019-09-19T00:54:18 < DisruptiveNL_> it does not crash
2019-09-19T00:54:20 < Cracki> buy another, see if that behaves differently

2019-09-19T00:55:13 < DisruptiveNL_> there must be it worked really well on the DISCOVERY
2019-09-19T00:55:16 < Cracki> maybe they did something to their stm32f429 chips that used to tolerate your code and now it doesn't

2019-09-19T00:56:12 < Cracki> for ze schipp?

2019-09-19T00:56:55 < Cracki> f429something
2019-09-19T00:56:57 < DisruptiveNL_> The DISC1 has a STM32F429ZIT6 = DISC1
2019-09-19T00:57:09 < Cracki> ah you need old data brief
2019-09-19T00:57:18 < Cracki> is the marking on the chip too shit to read?

2019-09-19T01:00:08 < Cracki> it says f429 disco, or does it say just f4 disco?
2019-09-19T01:00:08 < DisruptiveNL_> ?

2019-09-19T01:12:29 < catphish> they will be empty in production
2019-09-19T01:12:48 < Cracki> hint for the round corners: pick inner and outer radii so they're concentric. makes the wall uniform
2019-09-19T01:13:19 < grummund> yeah the one's along the left edge as pictured
2019-09-19T01:13:42 < Cracki> be careful tho that the slicer doesn't flip its shit because of numerics. a 0.8mm curved wall with 0.4mm nozzle might make it think there's space for 1.999 = 1.0 passes
2019-09-19T01:13:47 < catphish> oh, those, yes those need to be soldered, there's a battery clipped underneath

2019-09-19T01:24:48 < Cracki> "The rdimon library (librdimon.a) is actually built from newlib(libgloss), you can find it in directory "newlib/libgloss/arm/" in newlib package after extracting "gcc-arm-none-eabi-4_6-2012q2-20120614-src.tar.bz2"." https://answers.launchpad.net/gcc-arm-embedded/+question/212673
2019-09-19T01:24:48  * grummund is using it.
2019-09-19T01:25:08 < Cracki> so it's not its own library...
2019-09-19T01:25:40 < Cracki> and what the fuck kinda name is libgloss
2019-09-19T01:26:04 < grummund> if you link with, -lrdimon, then prinft will send via the debugger to the console in your IDE.
2019-09-19T01:26:04 < Cracki> does lennart poettering preside over newlib now? did he decide to change his pronouns?
2019-09-19T01:26:08 < Cracki> ic ic
2019-09-19T01:26:13 < Cracki> without SWO?
2019-09-19T01:26:17 < grummund> yes
2019-09-19T01:26:23 < Cracki> hm okeh
2019-09-19T01:26:47 < grummund> cortex-M0
2019-09-19T01:26:53 < Cracki> that has no traceswo?
2019-09-19T01:27:06 < grummund> hrm.
2019-09-19T01:27:10 < Cracki> idunno
2019-09-19T01:27:15 < grummund> not my board, anyways.
2019-09-19T01:27:22 < Cracki> I wouldn't use semihosting for that if I have swo
2019-09-19T01:27:33 < grummund> why?
2019-09-19T01:27:56 < Cracki> swo is fast and dedicated, semihosting has the debugger poll a section of memory
2019-09-19T01:28:31 < grummund> that explains why it updates once a second regardless of what's printed
2019-09-19T01:28:34 < Cracki> it's out only tho
2019-09-19T01:28:51 < Cracki> so if you want features of semihosting such as moving data _into_ the chip, there's just semihosting
2019-09-19T01:29:01 < Cracki> swo can trigger that tho
2019-09-19T01:29:03 < Cracki> lol no
2019-09-19T01:29:16 < Cracki> the once a second is whatever eclipse's traceswo plugin (or semihosting plugin) does
2019-09-19T01:29:24 < grummund> oh
2019-09-19T01:29:43 < Cracki> at least truestudio 9.3 (the last one)'s serial wire viewer updates at ~1 hz
2019-09-19T01:29:47 < Cracki> and it's awful shit
2019-09-19T01:30:58 < Cracki> i expect that to maybe have a sensible packetizing timeout of 10-100 ms, but not this 1 second seemingly polling behavior
2019-09-19T01:31:43 < grummund> cubemx doesn't seem to support semihosting or swo as options.
2019-09-19T01:32:43 < Cracki> it does
2019-09-19T01:32:47 < grummund> you need to edit the linker options and jump through a couple of hoops to get it to work.
2019-09-19T01:32:51 < Cracki> not quite
2019-09-19T01:32:52 < grummund> hmm, how?
2019-09-19T01:33:23 < Cracki> just a moment, booting cubemx
2019-09-19T01:33:33 < Cracki> https://community.st.com/s/question/0D50X0000BGtk3B/how-to-activate-trace-swo-stm32l412-in-cubemx
2019-09-19T01:33:48 < Cracki> and then you might have to edit something in syscalls.c to use ITM_SendChar
2019-09-19T01:34:03 < Cracki> current cubeshit can't mix freertos and newlib
2019-09-19T01:34:07 < grummund> what about semihosting?
2019-09-19T01:34:16 < Cracki> newlib uses malloc everywhere, but the wrong kind for freertos
2019-09-19T01:34:25 < Cracki> no clue about semihosting
2019-09-19T01:35:53 < Cracki> semihosting is an attribute of how the program is compiled, so that might be found in whatever IDE you use
2019-09-19T01:36:19 < grummund> it's using the makefile output by cubemx
2019-09-19T01:36:52 < Cracki> allow me to give you google's number one result http://shawnhymel.com/1840/how-to-use-semihosting-with-stm32/

2019-09-19T01:37:54 < grummund> like i said, it works but there are hoops to jump through.
2019-09-19T01:38:49 < Cracki> here's a _write that uses ITM_SendChar to enable printf to SWO: https://ralimtek.com/stm32_debugging/
2019-09-19T01:39:35 < Cracki> if you have a stink china clone, it just needs a bodge wire to an unconnected pin for SWO to be usable
2019-09-19T01:39:45 < grummund> segger j-link
2019-09-19T01:40:03 < grummund> but no swo pin on the mcu
2019-09-19T01:40:16 < Cracki> I'm sure it's there, what mcu exactly?
2019-09-19T01:41:10 < grummund> the baby stm32f030f4
2019-09-19T01:41:15 < Cracki> cortex m3/4 have the necessary macrocells, m0 might not

2019-09-19T01:42:10 < Cracki> hm, that could be the case, so no luck for you
2019-09-19T01:42:38 < specing> grummund: don't bother with semihosting, use uart
2019-09-19T01:42:42 < grummund> semihosting works, but no thanks to cubemx.
2019-09-19T01:43:04 < grummund> specing: i'm just experimenting.
2019-09-19T01:45:57 < grummund> gnu mcu plugin for eclipse has a wizard for new project, it sets up the makefile with options for freestanding/semihosted and trace to swo/semihost etc. it all just works out of the box.
2019-09-19T01:46:40 < grummund> except it's based on the now legacy st stdperiph libraries.
2019-09-19T01:48:00 < grummund> so having played with a led blinky using that i though give cubemx a try.
2019-09-19T01:48:12 < Cracki> I think I'm getting high from the fumes the downstairs stoner produces
2019-09-19T01:49:01 < roomba> Cracki: that is most excellent.
2019-09-19T01:49:26 < grummund> could be, it causes paranoia you know?
2019-09-19T01:49:28 < roomba> I read an article today claiming that people who use dark themes are 10% less productive than people who use light themes.
2019-09-19T01:49:39 < Cracki> either the usual stoner moved out and now there's a turbo stoner living there, or the dude had a nervous breakdown and is now selfmedicating like never before
2019-09-19T01:49:57 < Cracki> discriminating against blacks?

2019-09-19T01:50:25 < Cracki> same shit as 4 spaces 1 tab
2019-09-19T01:50:30 < roomba> I'm going to try using a light theme for a while and see how it goes.
2019-09-19T01:50:38 < roomba> see if I "feel" any different.
2019-09-19T01:50:38 < Cracki> 4 spaces is the fascism that's perpetrated in corporate domains
2019-09-19T01:50:43 < Cracki> tabs is what the free spirits use
2019-09-19T01:50:57 < roomba> my level of productivity is so low it's impractical to measure.
2019-09-19T01:51:01 < Cracki> 4 spaces is for blub programmers
2019-09-19T01:51:02 < BrainDamage> just use what the hell you're comfortable with
2019-09-19T01:51:15 < BrainDamage> I use a dark theme on my phone and light on my pc
2019-09-19T01:51:24 < Cracki> ¯\_(ツ)_/¯ the key is tab anyway, all editors can translate or emulate seamlessly
2019-09-19T01:51:50 < roomba> BrainDamage: if you have OLED display, this makes sense to use black themes.
2019-09-19T01:51:54 < BrainDamage> key vs symbol is a different thing, there's no unique map to keycode and codepoint
2019-09-19T01:52:12 < BrainDamage> roomba: yup, more battery life
2019-09-19T01:52:12 < Cracki> the worst an editor can do is not remove all 4 spaces when I backspace a "tab" of indentation, but that's easy to fix
2019-09-19T01:52:27 < BrainDamage> I prefer tab codepoint too
2019-09-19T01:52:37 < roomba> BrainDamage: the science says there isn't any diff in black vs white themes. the backlight brightness is what matters instead.
2019-09-19T01:53:14 < roomba> switching to a light theme is an experiment to see if it helps me focus better. entirely subjective. likely a placebo. but i'm trying it.
2019-09-19T01:53:17 < Cracki> I think I prefer tab character because it's the key I hit, and editors used to suck at dedenting properly with backspace (shift-tab always works)
2019-09-19T01:53:36 < BrainDamage> I prefer tab because it can be handled by machines way better
2019-09-19T01:53:47 < roomba> mind you, i have been using dark themes for _everything_ for ... ever.
2019-09-19T01:53:48 < Cracki> for lighting I go with what's least tiring... and the less surrounding light, the less tiring it is to me
2019-09-19T01:54:11 < Cracki> if the screen isn't the brightest thing in my field of vision, that's tiring
2019-09-19T01:54:17 < BrainDamage> so I don't have to care if this document has 4 spaces for identation or 3
2019-09-19T01:54:26 < BrainDamage> because that's just representation, not the data
2019-09-19T01:54:55 < Cracki> that too, I sometimes like to set tab size lower, sometimes a little wider

2019-09-20T00:34:45 < catphish> today i met a really nice police woman
2019-09-20T00:35:03 < catphish> i can only imagine it was her first week on the job, because she was genuinely happy
2019-09-20T00:35:18 < jadew> did you ask her out?
2019-09-20T00:35:33 < catphish> she was just directing traffic after an accident, but she seemed so happy to be doing it
2019-09-20T00:35:46 < jadew> maybe she was happy about the accident
2019-09-20T00:35:49 < catphish> i assume that after 6 months of being a police officer that all changes
2019-09-20T00:36:11 < Steffanx> Who knows
2019-09-20T00:36:42 < catphish> i did not ask her out, perhaps i should have
2019-09-20T00:37:01 < catphish> i was on a motorbike being "directed" at the time
2019-09-20T00:37:34 < catphish> my new (amazing) bike
2019-09-20T00:37:45 < catphish> </anecdote>
2019-09-20T00:38:14 < jadew> I met a policewoman once too, that was lit up when I asked her a question
2019-09-20T00:38:55 < catphish> was it an inappropriate question? did she truncheon you then arrest you for sexual assult?
2019-09-20T00:39:44 < jadew> if she answered yes, is it still considered an inappropriate question?
2019-09-20T00:40:25 < catphish> they never do
2019-09-20T00:40:43 < jadew> that's true
2019-09-20T00:41:03 < Cracki> >officer arrests you so they can sexually arrest you
2019-09-20T00:41:09 < Cracki> *assault :P
2019-09-20T00:41:21 < jadew> that's not a bad deal
2019-09-20T00:41:33 < Cracki> with a truncheon
2019-09-20T00:41:38 < jadew> heh
2019-09-20T00:42:27 < jadew> I was just thinking now... catphish is right, they never do
2019-09-20T00:43:29 < jadew> with a few exceptions, all my interactions with women involved some sort of game, in order to get to the "yes"
2019-09-20T00:44:29 < jadew> they're probably wired to enjoy watching you work for it
2019-09-20T00:44:45 < Cracki> gay biotechnologists are working on mpreg to solve that exact problem
2019-09-20T00:45:08 < jadew> what's mpreg?
2019-09-20T00:45:12 < Cracki> :3
2019-09-20T00:45:33 < jadew> ah, I got it
2019-09-20T00:45:37 < jadew> lol
2019-09-20T00:46:38 < Cracki> if she chases you, you don't have to work for it
2019-09-20T00:47:00 < jadew> that only happened once
2019-09-20T00:47:08 < jadew> and it freaked me out, not sure why
2019-09-20T00:47:11 < Cracki> that's what "conspicuous consumption" like sports cars and yachts are for
2019-09-20T00:47:57 < Cracki> it freaks you out because a woman chasing a man is a psychological abnormality
2019-09-20T00:48:10 < Cracki> it's not supposed to happen, it indicates insanity
2019-09-20T00:48:43 < Cracki> it's like when you get the creeps when you interact with a psychopath. you sense the danger.
2019-09-20T00:48:56 < jadew> heh, maybe
2019-09-20T00:48:58 < Cracki> they can act but it feels wooden
2019-09-20T00:49:04 < catphish> i've never played such games
2019-09-20T00:49:36 < jadew> catphish, you only say that because it's so natural you don't even realize it
2019-09-20T00:49:45 < catphish> maybe
2019-09-20T00:50:07 < Cracki> if you're habitually playful, you really don't notice
2019-09-20T00:50:15 < catphish> but i'm weird and don't really follow social conventions for the sake of it, it's possible i just got lucky and encountered women who feel the same
2019-09-20T00:50:22 < Cracki> if you've been taught to do what women say, you're fucked
2019-09-20T00:51:14 < kakimir32> rip
2019-09-20T00:52:21 < catphish> it's also possible that being attractive and having a good job is enough :)

2019-09-20T00:53:47 < kakimir32> sorry day
2019-09-20T00:54:23 < kakimir32> how to pick a nick 101
2019-09-20T00:54:23 < Steffanx> Is it?
2019-09-20T00:54:24 < jadew> 3rd one is for the water hose?
2019-09-20T00:55:05 < kakimir32> or halogen gas
2019-09-20T00:55:07 < jadew> so what's that kakimir32? looks like a power supply
2019-09-20T00:55:16 < kakimir32> it is
2019-09-20T00:55:16 < Steffanx> Hows it NASsing kakimir32?
2019-09-20T00:55:20 < jadew> is it one of those cheap DIY programmable power supply kits?
2019-09-20T00:57:33 < jadew> anyone else got a transferwise account?
2019-09-20T00:57:54 < kakimir32> jadew: indeed
2019-09-20T00:58:03 < Steffanx> What is it jadew?
2019-09-20T00:58:15 < kakimir32> Steffanx: not much happening
2019-09-20T00:58:43 < jadew> Steffanx, you probably missed the convo, it's a payment system

2019-09-20T00:59:06 < jadew> you get a debit card connected to your account and payments in any currency get converted at the interbank rate
2019-09-20T00:59:44 < jadew> I was planning to use it to save some cash on the conversion fees
2019-09-20T01:00:23 < jadew> GBP (paypal) => RON (my bank)
2019-09-20T01:00:36 < jadew> and then RON (my bank) => Whatever (online shops)
2019-09-20T01:01:10 < jadew> but they're taking for ever to verify my account
2019-09-20T01:08:48 < kakimir32> Steffanx: my transfers to nas are only 30MBps?
2019-09-20T01:08:55 < kakimir32> encrypted comms?
2019-09-20T01:09:18 < kakimir32> my craptop turns hot and stuff
2019-09-20T01:12:57 < kakimir32> Steffanx: I plan to have 2 x 500G, 4 x 1T, 2 x 2T
2019-09-20T01:13:12 < kakimir32> does it make any sense and can it be configured any way?
2019-09-20T01:13:50 < kakimir32> or let's say 4 x 1T and 2 x 2T
2019-09-20T01:14:09 < kakimir32> can I make one zraid of it that makes any sense?
2019-09-20T01:14:20 < kakimir32> other than striping
2019-09-20T01:15:05 < catphish> today i was puzzled why why wifi speed isn't the same in both directions
2019-09-20T01:16:14 < kakimir32> indeed
2019-09-20T01:16:29 < kakimir32> I noticed it with my wireless bridges
2019-09-20T01:17:06 < catphish> i set up a bridge today between 2 buildings, 40Mbit one way, 80Mbit the other way
2019-09-20T01:18:22 < catphish> the obvious answer would be that the RX end picking up interference would cause slower reception, but weirdly trasmitting from the omni to the directional antenna was slower
2019-09-20T01:18:46 < catphish> i don't think i'll ever really understand RF
2019-09-20T01:20:07 < kakimir32> now I have symmetrical devices in my link
2019-09-20T01:20:09 < Cracki> less reception
2019-09-20T01:20:12 < kakimir32> I should test it again
2019-09-20T01:20:39 < Cracki> directional can do its best to pick up what omni sent, but if directional can direct, omni will pick it up better
2019-09-20T01:21:23 < kakimir32> what did you use catphish?
2019-09-20T01:21:28 < kakimir32> devices
2019-09-20T01:21:34 < kakimir32> exact brand and model
2019-09-20T01:21:37 < kakimir32> just interested
2019-09-20T01:25:31 < catphish> kakimir32: i'm afraid i don't know, at my end was a UBNT nanoatation (a low gain directional CPE device), it was preconfigured by a friend to point to an omni he has on a neaby roof
2019-09-20T01:25:42 < catphish> the omni must me airmax too
2019-09-20T01:25:56 < kakimir32> loco M2?
2019-09-20T01:26:08 < kakimir32> M5?
2019-09-20T01:26:09 < catphish> i guess a rocket
2019-09-20T01:27:01 < catphish> my end is "nanostation ac"
2019-09-20T01:27:32 < catphish> the omi end is some kind of airmax omni, but i don't know the details
2019-09-20T01:28:25 < catphish> "Loco5AC" maye
2019-09-20T01:28:42 < catphish> it's tiny :)
2019-09-20T01:29:00 < catphish> yeah, must be Loco5AC

2019-09-20T03:01:57 < mawk> what if you enable dnscrypt ?
2019-09-20T03:01:59 < mawk> can it see it too ?
2019-09-20T03:02:07 < mawk> I guess yeah, using the rDNS, but less precise
2019-09-20T03:02:38 < mawk> latest firefox has dnscrypt option, maybe chrome too
2019-09-20T03:02:42 < kakimir32> dnscrypt?
2019-09-20T03:02:46 < mawk> dns over tls
2019-09-20T03:02:49 < mawk> prevents the DPI
2019-09-20T03:07:20 < kakimir32> okay it sees netflix too
2019-09-20T03:09:53 < Cracki> might it reverse lookup the IPs that are spoken to
2019-09-20T03:10:48 < kakimir32> maybe something more complex than that
2019-09-20T03:11:14 < kakimir32> okay it sees I did debian/ubuntu update
2019-09-20T03:11:16 < Cracki> sure nothing does just a single thing

2019-09-20T04:26:30 < mawk> so I must peek the type, if it's a dictionnary or an array I must recurse into it
2019-09-20T04:26:37 < mawk> it could be arbitrarily nested

2019-09-20T04:42:52 < dongs> like why would you even do that
2019-09-20T04:42:59 < dongs> lunix has no power management or support for anything mobile properly
2019-09-20T04:44:39 < dongs> like i can see installing lunix on some $200 netbook beacuse youre retarded and watching shit scroll on 80x25 console while atom N1488 tries to compile kernel with make -j 9000 because reasons

2019-09-20T05:10:12 < Cracki> registry doesn't work for that anymore, you must use the windows firewall

2019-09-20T20:48:59 < Cracki> upgrdman, i got that 8widgetpack or something, and then I have a cpu widget and a gpu widget
2019-09-20T20:49:45 < Cracki> all the gadget stuff is original. either it's still in win10 or they took "old" dlls and repackaged them
2019-09-20T20:50:01 < Cracki> *8gadgetpack
2019-09-20T20:50:32 < Cracki> the gpu gadget I have is "(c) 2010 by Orbmu2k"
2019-09-20T20:50:57 < Cracki> for my gtx560 it shows fan, vpu, gpu, ram, two clocks, voltage

2019-09-20T21:58:47 < upgrdman> Cracki, hmm interesting. can the widgets be shoved into the taskbar, or is it just a desktop widget?
2019-09-20T21:59:04 < Cracki> good old gadgets, no taskbar docking
2019-09-20T21:59:13 < Cracki> I have a taskbar widget for battery on my win10 tho
2019-09-20T21:59:33 < Cracki> so that's doable in principle but I haven't looked or stumbled upon anything that shows gpu there
2019-09-20T21:59:44 < upgrdman> k
2019-09-20T22:00:24 < Cracki> nvidia control panel seems to have an option to make it a tray icon
2019-09-20T22:01:08 < Cracki> desktop menu, the two to the right of the file menu
2019-09-20T22:01:37 < Cracki> it's a "rainbow waffle" icon, merely shows whether gpu is active or not, no gauge
2019-09-20T22:02:59 < Cracki> "xmeters" sounds modular, might have a gpu gauge https://www.thewindowsclub.com/cpu-network-disk-usage-xmeters
2019-09-20T22:03:58 < upgrdman> i tired xmeters, no gpu
2019-09-20T22:04:18 < upgrdman> and sadly my laptop is just intel gpu, so nvidia will prolly tell me to suck a dick
2019-09-20T22:04:43 < Steffanx> hah
2019-09-20T22:04:58 < Cracki> the thing I use is "gpu observer". I only use it on desktop tho, I think it added a few watts of drain on my laptop
2019-09-20T22:06:42 < Cracki> hwmonitor can show you numerical gauges as tray icons
2019-09-20T22:06:49 < Cracki> that's not a separate "toolbar" tho
2019-09-20T22:07:19 < Cracki> haven't tried it yet https://www.cpuid.com/softwares/hwmonitor.html
2019-09-20T22:08:02 < Cracki> and might just show temperatures... but it does know other dimensions such as percents and rpms

2019-09-20T22:58:57 < Cracki> dexpot, the virtual desktop thingy, does something slightly different because their grid thing doesn't list as a toolbar in the contex tmenu

2019-09-20T23:56:09 < kakimir32> definitelly not
2019-09-20T23:56:48 < Steffanx> For sure
2019-09-20T23:58:33 < Steffanx> so did you speed up your nas yet mr kakimir32?
2019-09-20T23:58:39 < kakimir32> let's see if there was any ultimate killer tracks in tonights radio playlist
2019-09-20T23:58:59 < kakimir32> I need to diagnose it first but not priority atm
2019-09-20T23:59:07 < kakimir32> what is the bottleneck etc.

2019-09-21T00:00:07 < jadew> aandrew, how's the move?
2019-09-21T00:00:44 < aandrew> jadew: meh. I don't much like vancouver but I'm in the middle of hte city too, if it were Toronto I'd hate it too
2019-09-21T00:00:56 < jadew> heh
2019-09-21T00:05:35 < aandrew> got a workable office set up though: https://imgur.com/a/CQaxK4q

2019-09-21T00:06:14 < jadew> nice
2019-09-21T00:06:21 < jadew> I see you got the ksger soldering station
2019-09-21T00:06:38 < jadew> how do you like it?
2019-09-21T00:06:45 < aandrew> yeah. not bad. I need to see if it has the magnetic sensor or not
2019-09-21T00:07:07 < jadew> it has a switch inside with a ball or something
2019-09-21T00:07:10 < aandrew> it's pretty good. it's no metcal, but I think with a heavier (chisel) tip it'll be good and hot. I have a tiny tip on it atm
2019-09-21T00:07:12 < jadew> magnetic sensor would be nice
2019-09-21T00:07:28 < jadew> I'm using D16
2019-09-21T00:08:25 < aandrew> I've got a JL02 in it right now but have D16 and K tips too (came with three)
2019-09-21T00:08:35 < aandrew> but I mean for the money, it's a very capable little iron
2019-09-21T00:08:51 < aandrew> what's the ball sensor good for? you have to hold it upright or something to shut it off?
2019-09-21T00:09:09 < jadew> aandrew, I'm not sure, I don't think it works very well
2019-09-21T00:09:26 < jadew> there's one with a mercury switch in it, but I didn't want mercury in my chinese iron
2019-09-21T00:09:32 < aandrew> yeah I just did a quick test, it did nothing :-)

2019-09-21T00:43:23 < mawk> cmsis isn't a rtos
2019-09-21T00:43:27 < mawk> you mean keil ?
2019-09-21T00:43:42 < mawk> cmsis is the interface for a RTOS
2019-09-21T00:43:46 < qyx> keil is neither
2019-09-21T00:44:03 < mawk> I mean keil RTX
2019-09-21T00:44:11 < grummund> cmsis was the bait, youtook it ;)
2019-09-21T00:44:26 < mawk> I won you mean
2019-09-21T00:44:59 < grummund> you can use cmsis interface to either, aiui.
2019-09-21T00:45:13 < mawk> yes both implement the CMSIS interface
2019-09-21T00:45:30 < grummund> it's still a choice then
2019-09-21T00:45:48 < mawk> yes
2019-09-21T00:45:53 < mawk> you can use the non-CMSIS interface too
2019-09-21T00:45:57 < mawk> and get more options
2019-09-21T00:46:46 < grummund> cubemx generates code for cmsis with freertos underneath
2019-09-21T00:46:56 < mawk> yeah
2019-09-21T00:46:58 < mawk> their choiec
2019-09-21T00:47:04 < mawk> choiec
2019-09-21T00:47:07 < mawk> choice 
2019-09-21T00:47:07 < mawk> lol
2019-09-21T00:47:27 < mawk> you can erase everything and use the freertos API instead

2019-09-21T00:48:04 < grummund> so freertos wins?
2019-09-21T00:48:56 < mawk> no we said nothing about that
2019-09-21T00:49:02 < mawk> but freertos is free, keil rtx isn't
2019-09-21T00:49:06 < mawk> µOS dunno about it
2019-09-21T00:49:09 < mawk> freertos should be enough for you
2019-09-21T00:49:10 < englishman> surely you mean Amazon FreeRTOS
2019-09-21T00:49:14 < mawk> yes
2019-09-21T00:49:19 < grummund> cubemx also uses an older freertos.
2019-09-21T00:49:19 < mawk> please accept my apologies lord Bezos
2019-09-21T00:49:30 < mawk> what do you mean older ? cubemx uses freertos with the CMSIS interface
2019-09-21T00:49:37 < Cracki> uses freertos v9 or so
2019-09-21T00:49:39 < mawk> ah older freertos, yeah I gues
2019-09-21T00:49:39 < mawk> s
2019-09-21T00:49:40 < Cracki> they're at 10 iirc
2019-09-21T00:50:00 < grummund> cubemx has freertos 9
2019-09-21T00:50:01 < Cracki> 8.2.3 was the last before amzn ate it
2019-09-21T00:50:04 < mawk> anyway since it uses the CMSIS interface you can swap out for the new one, but you won't use new features if you still use the same CMSIS interface
2019-09-21T00:50:12 < englishman> cube freertos works fine
2019-09-21T00:50:22 < mawk> but there is amazon freertos and upstream freertos still Cracki right ?
2019-09-21T00:50:27 < Cracki> no clue
2019-09-21T00:50:28 < mawk> amazon-free rtos
2019-09-21T00:50:30 < mawk> I hope
2019-09-21T00:50:42 < mawk> the freertos guy said it in its "don't panic amazon hired me" blog post iirc
2019-09-21T00:50:51 < Cracki> so it's all owned
2019-09-21T00:51:01 < mawk> yeah they hired the lead dev
2019-09-21T00:51:05 < grummund> amazon freertos has ditched all the old ports
2019-09-21T00:51:14 < Cracki> "extension" https://en.wikipedia.org/wiki/FreeRTOS#Amazon_FreeRTOS
2019-09-21T00:51:36 < Cracki> "stewardship"
2019-09-21T00:53:02 < qyx> grummund: try chibios if you feel adventurous enuff
2019-09-21T00:53:27 < grummund> if you compare the source trees for 'amazon freertos' and 'freertos' only the kernel matches
2019-09-21T00:53:53 < grummund> qyx: i will take a look, thanks.
2019-09-21T00:54:38 < qyx> the bad part was its HAL, but you don't have to use it
2019-09-21T00:54:45 < qyx> also, gpl
2019-09-21T00:54:53 < qyx> but iirc it was changed to apache or so
2019-09-21T00:54:59 < grummund> 'freertos' in sourceforge was slightly ahead of 'amazon freertos' on github when i looked.
2019-09-21T00:56:08 < upgrdman> people still use SF?
2019-09-21T00:56:27 < upgrdman> every time i go to SF the web site is a mess and full of shit
2019-09-21T00:56:47 < upgrdman> i think the only software i use that's still on SF is teraterm
2019-09-21T01:00:24 < grummund> so plain freertos is preferred to using it with cmsis layer?
2019-09-21T01:02:22 < mawk> no
2019-09-21T01:02:34 < mawk> I have no precise opinion on this
2019-09-21T01:02:45 < mawk> using it with cmsis works, until the point you need more, then switch to freertos API
2019-09-21T01:03:01 < mawk> what I don't like I think is mixing the two interfaces, but it's perfectly possible
2019-09-21T01:03:15 < mawk> both sets of symbols are in the global namespaces, use either one
2019-09-21T01:03:29 < mawk> it amounts to the exact same thing, you can read the freertos CMSIS binding source code it's pretty short
2019-09-21T01:03:52 < mawk> cmsis routines do a little more than the raw freertos ones in some cases so it may be convenient to use CMSIS
2019-09-21T01:05:21  * grummund plans to give them all a spin, including µOS++.

2019-09-21T12:01:01 < jadew> hmm, got my controleo3 controller set up, first run, it smoked the boards
2019-09-21T12:01:52 < jadew> I wonder now if the profile was wrong or if the temperature probe was off
2019-09-21T12:02:01 < jadew> maybe I should do a run without boards in it

2019-09-21T12:13:13 < jadew> antto, you should, they're much tastier than if you have them raw
2019-09-21T12:13:46 < antto> no
2019-09-21T12:14:14 < antto> i do have a "party grill" thing, maybe that's similar to a toaster oven

2019-09-21T16:28:15 < dongs> im basically copypasting STM32 code and using it
2019-09-21T16:28:24 < englishman> so it even has nvic etc
2019-09-21T16:28:26 < englishman> ?
2019-09-21T16:28:28 < BrainDamage> riscv lacks standardized periferials yet

2019-09-21T16:34:03 < Steffanx> not unlikely.
2019-09-21T16:34:32 < dongs> nice thing, BFF setting on GD32 SPI doesn't require peripheral reinit
2019-09-21T16:34:46 < dongs> so i can switch between 8/16bit data modes with a couple instructions
2019-09-21T16:35:51 < dongs> i forget if that was a requirem,ent on F1, it definitely was on F3
2019-09-21T16:36:00 < dongs> that you had to disable SPI before switching mode
2019-09-21T16:41:44 < dongs> ah called DFF in F1
2019-09-21T16:41:48 < dongs> and yeah, SPI must be disabled to switch it
2019-09-21T16:41:51 < dongs> but not on GD32.

2019-09-21T23:38:34 < karlp> qyx: hence not really thinking it fits well. motivation is that the peripheral support code is "same" just s/arm-none-eabi/riscv-blah-wop/g

2019-09-22T00:45:31 < qyx> yes
2019-09-22T00:45:46 < qyx> actually .hr, .hu, .sk
2019-09-22T00:45:57 < karlp> we managed a double the other day. drove to triest via slovenia for the afternoon, got tickets in both countries :)
2019-09-22T00:45:57 < qyx> or through slovenia and austria
2019-09-22T00:46:25 < BrainDamage> there's actually a super weird thing where hungarian and finnish have the same root

2019-09-22T00:47:13 < karlp> trieste was better than I expected. and way mor eheavy industry fallout than rijeka, despite what BrainDamage said, at least on the roads we drove...
2019-09-22T00:47:44 < antto> NSFW: https://i.imgur.com/FoEJQcS.mp4
2019-09-22T00:47:47 < BrainDamage> more or less?
2019-09-22T00:48:12 < karlp> trieste had more disused wasteland
2019-09-22T00:48:17 < karlp> rijeka had less.
2019-09-22T00:48:25 < karlp> but we just drove through rijeka on the freeway.
2019-09-22T00:48:49 < BrainDamage> trieste is pretty industrial, yes, especially slighy past the city center
2019-09-22T00:48:50 < karlp> triest had way more, way bigger, way.... everything, but some reallllly nice rusty dead industry skeletons
2019-09-22T00:48:53 < BrainDamage> there's a big refinery
2019-09-22T00:49:05 < BrainDamage> near venice too
2019-09-22T00:49:44 < BrainDamage> rijeka is a nightmare for the traffic if you go through
2019-09-22T00:49:57 < karlp> got a nice squat toilet in triest too, hadn't seen them since I was in turkey
2019-09-22T00:50:10 < karlp> rijeka was perfectly smooth for us traffic wise at least.
2019-09-22T00:50:21 < karlp> we just freewayed all the way through.

2019-09-22T00:50:33 < BrainDamage> yeah, the traffic's inside
2019-09-22T00:50:42 < qyx> aren't squat toilets quite common in italy too?
2019-09-22T00:50:52 < BrainDamage> in old buildings, yes
2019-09-22T00:50:55 < qyx> at least I encountered them along highways
2019-09-22T00:51:26 < qyx> or idk if it is actually squat toilet, just a hole in the floor
2019-09-22T00:51:57 < BrainDamage> there should be risers for the feet and possibily a corrugated surface to prevent slip
2019-09-22T00:52:04 < BrainDamage> and hopefully water drainage ...
2019-09-22T00:52:06 < karlp> last time I was in italy I got a lot of toilets that had no seats, but were still "western" but this was straight up classic squat.
2019-09-22T00:52:15 < karlp> yeah, "proper" squat, not jus a hole.
2019-09-22T00:52:28 < BrainDamage> yeah, toilet vandalism is rampant here
2019-09-22T00:52:56 < BrainDamage> most people just plain refuse to enter a toilet that doesn't have a caretaker
2019-09-22T00:53:02 < karlp> yeah, that was how the lack of seats was explained to me around napoli
2019-09-22T01:14:41 < roomba> midieval kings and nobles were rife with disease and mental disorder due to their lavish lifestyles. contemporary western culture is like, "we can live like that, and just take pills to solve all the problems of such a lifestyle"

2019-09-22T02:32:48 < jadew> wth is toilet vandalism?
2019-09-22T02:33:13 < jadew> and why are other toilet goers afraid of it? are they getting picked on?
2019-09-22T02:33:23 < jadew> or it's because of the state the toilets are in?
2019-09-22T02:34:19 < roomba> typically walmart employees will "vandalize" all the toilets except one, and smear hepatitis over it.
2019-09-22T02:34:27 < roomba> they're just doing thier job
2019-09-22T02:34:47 < jadew> so toilet vandalizing it's a think in the US too?
2019-09-22T02:34:56 < jadew> they destroy the toilets?
2019-09-22T02:35:09 < mawk> they misuse the toilet
2019-09-22T02:35:16 < jadew> they shit on the floor?
2019-09-22T02:35:16 < roomba> yea it's not really vandalism
2019-09-22T02:35:19 < mawk> like they forget there is a button for flushing
2019-09-22T02:35:27 < jadew> right
2019-09-22T02:35:32 < roomba> it's more like the majority of people have no basic hiegene
2019-09-22T02:36:14 < roomba> just think. you're sitting on a seat that someone else had their bare ass on
2019-09-22T02:36:21 < roomba> only minutes prior
2019-09-22T02:36:29 < jadew> I am not
2019-09-22T02:36:34 < roomba> and in the US, those people are sweatting HIV and herpes and hepatitis
2019-09-22T02:36:47 < roomba> some of them might even have open sores on their ass
2019-09-22T02:37:01 < jadew> I put toilet paper on the seat even if it's in a luxury location
2019-09-22T02:37:11 < roomba> you sit there, and the poures of your skin are soaking that shit up - and it eventually reaches your blood stream
2019-09-22T02:37:40 < mawk> lol
2019-09-22T02:37:46 < roomba> jadew: same
2019-09-22T02:37:53 < roomba> i have it down to a science
2019-09-22T02:37:54 < mawk> some toxins go through skin, but not really bacteria
2019-09-22T02:37:59 < mawk> I think
2019-09-22T02:38:14 < mawk> but the dirtiness sticks to the skin
2019-09-22T02:38:17 < mawk> you carry it everywhere
2019-09-22T02:38:24 < jadew> correct, also most viruses don't make it through the skin
2019-09-22T02:38:30 < jadew> certainly not the ones he listed
2019-09-22T02:38:53 < jadew> and you don't find them in bodily liquids either
2019-09-22T02:39:01 < jadew> maybe herpes
2019-09-22T02:39:48 < roomba> i'm not willing to take the chance
2019-09-22T02:39:58 < roomba> how would you study it?
2019-09-22T02:40:18 < roomba> maybe it's possible to train apes to sit on a toilet?
2019-09-22T02:40:34 < roomba> you can't exactly tell a test group of humans "here sit on this AIDS toilet"
2019-09-22T02:40:49 < mawk> take herpes cream and put it on guantanamo prisoners as part of an underground military study
2019-09-22T02:40:55 < mawk> like they always do in the US
2019-09-22T02:41:26 < roomba> that's not a controlled enough environment
2019-09-22T02:41:52 < roomba> how do we know if the herpes came from the cream on the toilet seat or from another inmate or a guard?
2019-09-22T02:42:23 < roomba> nature is cruel. human nature is nature.
2019-09-22T02:42:58 < roomba> so it's plausible that even gitmo guards are raping inmates on the regular
2019-09-22T02:44:50 < jadew> odds are it's not even rape
2019-09-22T02:45:21 < jadew> anyway, let's change the subject
2019-09-22T02:46:13 < jadew> what are some new and good movies?
2019-09-22T02:46:26 < roomba> that is an invalid question
2019-09-22T02:50:48 < jadew> I hate VAT

2019-09-22T12:22:45 < Steffanx> This rap comes from a time certain people were still self employed. Now they're all corporate monkeys. Which creates a different kind of (in)sanity.

2019-09-22T14:19:05 < catphish> grr my usb endpoint is too slow, i need to learn how to double buffering
2019-09-22T14:33:23 < zyp> really? IME it's easy enough to refill the buffer before the host repolls
2019-09-22T14:33:49 < zyp> but of course it depends on the latency of your application and everything
2019-09-22T14:44:24 < dongs> sup dongs
2019-09-22T14:44:39 < zyp> sup sup

2019-09-22T14:45:25 < Steffanx> tha sky
2019-09-22T14:46:24 < Steffanx> there?
2019-09-22T14:49:25 < Steffanx> that's not much
2019-09-22T14:55:14 < srk> zyp: pretty much, I only put .data and heap to ccm if available
2019-09-22T14:55:41 < srk> is .data + .bss good indicator of sram usage?
2019-09-22T14:56:42 < zyp> depends how much stack and heap you're using
2019-09-22T14:57:01 < srk> indeed
2019-09-22T14:57:06 < zyp> .data + .bss makes up static sram usage, stack and heap makes up dynamic
2019-09-22T14:57:33 < srk> wish there was a better way to inspect binaries than objdum
2019-09-22T14:58:12 < zyp> size?
2019-09-22T14:59:51 < srk> yeah but that won't tell me which parts of the program are using the most mem
2019-09-22T15:00:43 < srk> ah, nm & size
2019-09-22T15:02:52 < catphish> zyp: interesting, i got the impression from the docs that it simply wasn't possible to do full speed that way
2019-09-22T15:04:31 < catphish> i'm trying to send around 4Mbps, it's mostly ok but sometimes my buffer overflows
2019-09-22T15:05:02 < catphish> i realise that bulk transfer speed isn't guarenteed, but i feel that 4Mbps should be maintainable with a modest buffer
2019-09-22T15:05:20 < catphish> i'm using an 8kB buffer and 64k packets
2019-09-22T15:05:26 < catphish> *64 byte packets
2019-09-22T15:06:45 < zyp>  FS USB has a theoretical maximum of about 9.7 MB/s of actual throughput
2019-09-22T15:07:07 < zyp> 19 packets of 64B each per frame
2019-09-22T15:07:24 < catphish> maybe i'm just pushing it too far streaming at 4Mbit
2019-09-22T15:07:48 < zyp> sorry, Mb/s, 1.2 MB/s
2019-09-22T15:08:03 < zyp> I don't see any reason it shouldn't be able to do 4 Mb/s
2019-09-22T15:08:21 < catphish> for the most part it works, but sometimes it can't keep up
2019-09-22T15:08:25 < catphish> i guess that's to be expected :(
2019-09-22T15:08:28 < zyp> I haven't done any benchmarks myself on what I can do
2019-09-22T15:08:36 < catphish> since the throughput is never guarenteed
2019-09-22T15:08:47 < zyp> well, that's the point of bulk
2019-09-22T15:09:00 < zyp> if you want guaranteed capacity, go with isochronous
2019-09-22T15:10:28 < catphish> i haven't looked at isochronous
2019-09-22T15:11:34 < catphish> perhaps i'll look again at whether double buffering is actually required to maximize throughput
2019-09-22T15:11:37 < catphish> i believed it was
2019-09-22T15:12:25 < catphish> but i can't think of any sane reason it should be, as long as you fill the buffer before the next poll
2019-09-22T15:13:49 < catphish> i fear my requirements are probably just unrealistic
2019-09-22T15:14:20 < catphish> while 4Mbps is possible in theory, relying on it is clearly a problem
2019-09-22T15:24:26 < srk> zyp: FreeRTOSes heap_5 can span multiple regions - https://www.freertos.org/a00111.html#heap_5
2019-09-22T15:26:14 < catphish> looks like an isochronous endpoint with a 512 byte payload would achieve 4Mbps
2019-09-22T15:26:35 < catphish> and since i'm streaming, that makes sense, i'll try it

2019-09-22T19:10:56 < catphish> Laurenceb_: excellent
2019-09-22T19:11:06 < Laurenceb_> kek
2019-09-22T19:11:16 < catphish> of course i don't believe you
2019-09-22T19:11:20 < Steffanx> There?
2019-09-22T19:15:47 < catphish> ugh, this double buffered flow is complex
2019-09-22T19:17:17 < Laurenceb_> oh yeah that
2019-09-22T19:17:27 < Laurenceb_> I never finished that
2019-09-22T19:17:46 < Laurenceb_> sorry - I discovered the AC97 issues before I got buffering solved

2019-09-22T19:25:16 < Laurenceb_> none
2019-09-22T19:25:28 < Steffanx> It was all wasted?
2019-09-22T19:25:29 < Laurenceb_> audio is much faster
2019-09-22T19:26:05 < Laurenceb_> yes, babbyshake is a waste of time
2019-09-22T19:26:09 < Steffanx> much faster as in development time? 
2019-09-22T19:26:10 < Steffanx> No way.
2019-09-22T19:27:06 < Laurenceb_> yes
2019-09-22T19:27:24 < Laurenceb_> no need for libusb crazyness
2019-09-22T19:28:05 < Steffanx> whokay. iirc you had a shitload of trouble with the audio part on the host side
2019-09-22T19:28:28 < Laurenceb_> not really - it was more the gui and stuff
2019-09-22T19:28:39 < Laurenceb_> and incorrect st documentation for their usb stack

2019-09-22T19:53:03 < catphish> specifically i can't really work out how one can give *both* buffers to the hardware peripheral, since it seems that it would be necessary to do so in order to allow it to move seamlessly from one to the other
2019-09-22T19:54:37 < Steffanx> someone must have done it.
2019-09-22T19:54:41 < Cracki> you give each in turn
2019-09-22T19:55:14 < Cracki> damn, I forgot what I read on it already...
2019-09-22T19:56:10 < Cracki> the trick seemed to be that the interrupt that handles a received block hands the empty buffer to the peripheral quickly, and processing the received block can take the appropriate time
2019-09-22T19:56:30 < Thorn> someone told me that if a part is specified from -40°C it doesn't mean it will start up at 40°C. is it actually true?
2019-09-22T19:56:44 < Cracki> there were two bits you juggle to indicate to the peripheral if the buffer is good to use or not (flow control)
2019-09-22T19:57:17 < Cracki> I think you actually did tell the peripheral about both buffers, but those flags govern flow
2019-09-22T19:57:19 < catphish> the problem i'm seeing is that there are 2 bits, one says which buffer the hardware is using, and one says which buffer the software is using, at the moment the hardware finishes using one, it'll want to use the other, but it can't because the software is still marked as using it
2019-09-22T19:57:30 < Cracki> Thorn, storage or operating?
2019-09-22T19:57:40 < catphish> you can't get "ahead" and hand the second buffer to the hardware in advance
2019-09-22T19:57:41 < Thorn> operational temperature range
2019-09-22T19:58:18 < Cracki> catphish, the hardware has a little time for a handler to run before it actually needs the new buffer... I think
2019-09-22T19:58:59 < Cracki> Thorn, one could argue that operating doesn't include startup but that's silly. I think if it doesn't start up within operating temperature, it's faulty
2019-09-22T19:59:26 < Thorn> apparently these requirements are different for commercial vs military grade parts
2019-09-22T19:59:28 < Cracki> external crystal might have different operating temp
2019-09-22T19:59:35 < Cracki> yes, binning
2019-09-22T19:59:41 < Thorn> no sources were provided to me though
2019-09-22T19:59:53 < Thorn> so I'm trying to find them if they exist
2019-09-22T19:59:54 < Cracki> so someone made shit up? :P
2019-09-22T20:00:06 < Cracki> is there at least authority behind the one who claims these things?
2019-09-22T20:01:06 < Cracki> catphish, if one bit is for "used by software", you just set that the other way so the next buffer isn't used by software, so the peripheral can use the buffer?
2019-09-22T20:01:14 < Cracki> it had this truth table. one state was illegal.
2019-09-22T20:04:03 < catphish> Cracki: the problem in my mind is that by setting it the other way, you're then telling it that you're using the previous buffer (the one the hardware needs to use first)
2019-09-22T20:04:26 < catphish> Cracki: ideally you'd want to flip the bit after the hardware has committed to using the first buffer, but before it needs the second one
2019-09-22T20:04:41 < Cracki> you have the RM in front of you?
2019-09-22T20:04:44 < catphish> yes
2019-09-22T20:06:07 < catphish> RM0394 page 1530
2019-09-22T20:09:56 < Cracki> When the application packet buffer usage is over, the software toggles the SW_BUF bit, writing ‘1 to it, to notify the USB peripheral about the availability of that buffer
2019-09-22T20:10:26 < Cracki> in my rm (0316) but I guess it's similar/same
2019-09-22T20:11:07 < Cracki> this implies that it goes from "claiming" this buffer, to claiming the currently peripheral-"owned" one
2019-09-22T20:11:22 < Cracki> those words aren't right, but close to right
2019-09-22T20:11:44 < Cracki> those are just bits. their meaning is only defined as a group
2019-09-22T20:13:03 < Cracki> their "truth tables" might not be explaining the reality that well
2019-09-22T20:13:11 < Cracki> this needs a state machine
2019-09-22T20:14:23 < Cracki> STAT bits are involved too
2019-09-22T20:15:46 < catphish> i was thinking that by writing SW_BUF, you'd end up creating the situation where SW_BUF==DTOG
2019-09-22T20:16:16 < Cracki> consider when you do that, and when the peripheral does it
2019-09-22T20:16:21 < catphish> the manual states indeed "the software toggles the SW_BUF bit, writing ‘1 to it, to notify the USB peripheral about the availability of that buffer" but the truth tables imply that this is a bad ide
2019-09-22T20:16:21 < Cracki> that makes a difference
2019-09-22T20:16:23 < catphish> *idea
2019-09-22T20:16:34 < Cracki> this is shit documentation
2019-09-22T20:16:50 < Cracki> I'd experiment, see if it works
2019-09-22T20:16:59 < Cracki> also hunt for code that claims to work with double buffering...
2019-09-22T20:17:23 < catphish> yeah i guess i'll carry on looking and experimenting and put the RM down for a whil
2019-09-22T20:17:25 < catphish> thanks!
2019-09-22T20:17:55 < Cracki> don't trust me. I haven't done this, only looked at it and then gave up caring becaue what I have has been good enough

2019-09-22T21:22:53 < zyp> for some reason Brother has decided to replace the 102mm wide tape I've been using with a 103mm wide tape
2019-09-22T21:24:56 < Steffanx> i escaped aaages ago Thorn
2019-09-22T21:25:41 < Steffanx> and ##*-offtopic was more your thing
2019-09-22T21:27:09 < Steffanx> and 103 doesnt fit, zyp?
2019-09-22T21:28:40 < Cracki> if brother did that, they did it because it still fits in their devices (or they're dumb) so you aren't using a brother device
2019-09-22T21:29:04 < Cracki> wanna install a razor blade that shaves off a millimeter?
2019-09-22T21:30:07 < Steffanx> what does mr zyp use the labels for that the extra 1mm is an issue?
2019-09-22T21:30:16 < zyp> Steffanx, it does, but original firmware and drivers for my printer didn't support it
2019-09-22T21:30:22 < Steffanx> ah
2019-09-22T21:30:31 < zyp> and the upgrade process was silly as fuck
2019-09-22T21:30:41 < Steffanx> windows only?
2019-09-22T21:30:53 < zyp> nah, just underdocumented
2019-09-22T21:31:26 < zyp> anyway, I kinda got it to work, now the only issue left is that the paper size selections are broken
2019-09-22T21:31:54 < zyp> if I select the old 102mm-sized labels I've always been using, printer complains about wrong paper size and won't print
2019-09-22T21:32:19 < zyp> and if I select the new 103mm option, it also complains, because for some fucked up reason that's apparently 104mm
2019-09-22T21:33:17 < zyp> so I need to make a new custom paper size, and those are not available in the Chrome print menu, so it kinda breaks my workflow
2019-09-22T21:37:53 < zyp> but whatever, if they're gonna be like that I'm just gonna buy some clone rolls of the 102mm tape

2019-09-22T22:27:22 < R2COM> i got my TIM3 configured with xor input for hall sensor, and for now just testing it with sig gen. just one channel, just to see it trigger an interrupt but even though TIM3 and clocks and interrupt setting enabled and clock configured right i cant see interrupt being triggered
2019-09-22T22:27:41 < R2COM> might be some trivial stuff missing but all things set up properly
2019-09-22T22:27:58 < kakimir32> R2COM is alive
2019-09-22T22:28:31 < R2COM> yo
2019-09-22T22:30:31 < kakimir32> how is innovation?
2019-09-22T22:30:39 < kakimir32> how is life?
2019-09-22T22:34:27 < R2COM> so, my sys clock is solid 48M (verified), my TIM3_clock = 48M / (47+1) = 1M [cuz PSC=47 for TIM3], now if i want say...set TIM3 period to 50ms (which is 20hz), then i put value TIM3_period = (1M/20)-1 = 49999
2019-09-22T22:34:46 < R2COM> so the period is larger than my 2ms period signal fed from signal gen
2019-09-22T22:35:04 < R2COM> so technically, if i enabled interrupt and all those settings in, i need to be able to trigger TIM3 interrupt
2019-09-22T22:35:23 < R2COM> kakimir32 its ok, innovating furiously
2019-09-22T22:37:58 < R2COM> so when TIM3 is configured with XOR setting from ch1,2,3 it actually generates interrupt upon any of those inputs change
2019-09-22T22:38:07 < R2COM> at least according to DS
2019-09-22T22:42:09 < R2COM> need to smoke on ref man more i guess
2019-09-22T22:42:29 < R2COM> their default lib code has all kinds of TIM examples except just the one i need

2019-09-23T01:11:27 < mawk> I'll come by plane
2019-09-23T01:11:31 < mawk> then I start ASAP if they take me
2019-09-23T01:11:47 < mawk> I will need to move all my things from paris to delft in no time
2019-09-23T01:11:51 < mawk> and I have no driving license
2019-09-23T01:12:01 < Steffanx> Hm
2019-09-23T01:12:51 < Steffanx> Better get to it then. Lessons in dutchland are €€€
2019-09-23T01:13:12 < Steffanx> Same as the exam(s)
2019-09-23T01:13:42 < Steffanx> Unless the theory exams are too difficult for you as well
2019-09-23T01:14:20 < mawk> here it's around 1000€ for the full package, same in NL ?
2019-09-23T01:14:55 < effractur> NL is at least 2k

2019-09-23T01:15:02 < BrainDamage> o_O
2019-09-23T01:15:10 < qyx> I got b/am for 300€ in 2008 here
2019-09-23T01:15:21 < BrainDamage> here you're required to pay only for the exam
2019-09-23T01:15:23 < effractur> for lessons and exam etc
2019-09-23T01:15:31 < BrainDamage> which is 300 bucks
2019-09-23T01:15:48 < BrainDamage> lessons will cost you from 500 to 1000 depending how long
2019-09-23T01:16:07 < BrainDamage> but it's perfectly doable to do it yourself
2019-09-23T01:16:09 < effractur> if your good you can do it for ~1000 but most people it costs around 2k
2019-09-23T01:16:14 < Steffanx> Nah 1700 here effractur ;)
2019-09-23T01:16:22 < mawk> 1700 = 2000

2019-09-23T01:16:55 < Steffanx> Big business 
2019-09-23T01:17:15 < BrainDamage> are you allowed to practice with a senior driver privately?
2019-09-23T01:17:23 < mawk> in FR yes
2019-09-23T01:17:35 < mawk> but you need the smaller exam for that, it's 200 or 300€
2019-09-23T01:17:37 < Steffanx> In dutchland. No
2019-09-23T01:17:51 < mawk> then you do 2 years with a senior driver, and you've got a probation license for 1 year
2019-09-23T01:17:59 < Steffanx> Unless it's on private property
2019-09-23T01:18:08 < mawk> and then if you didn't drive over an old lady you get the full license
2019-09-23T01:18:15 < BrainDamage> private property you don't even need a license
2019-09-23T01:18:31 < Steffanx> Yeah that's why you can practice :P
2019-09-23T01:18:47 < BrainDamage> a probational license here gives you 6 months of practice, you get one after passing the theory
2019-09-23T01:18:51 < effractur> and after your get your license you are a starting driver for the first 5 years
2019-09-23T01:18:54 < BrainDamage> and you can renew it
2019-09-23T01:19:22 < BrainDamage> back when i did there was no 'amateur driver', now's 2 years here iirc
2019-09-23T01:19:27 < Steffanx> Here you have something like that as well  but I recall that's only for people < 18 years old
2019-09-23T01:19:49 < effractur> Steffanx: for <18 you can get your licence but someone has to be next to you
2019-09-23T01:20:02 < effractur> but you still need to pay for the lessons 
2019-09-23T01:20:07 < BrainDamage> you can practice with the probation license with anyone which holds a license for longer than 10 years
2019-09-23T01:20:08 < Steffanx> Sure
2019-09-23T01:20:20 < BrainDamage> I remember practicing with my father
2019-09-23T01:21:24 < effractur> at least in NL you pratice in the area where you also will have your exam

2019-09-23T01:24:39 < effractur> BrainDamage: afaik
2019-09-23T01:25:12 < BrainDamage> the insurance is on the elder driver's responsibility
2019-09-23T01:25:44 < Steffanx> I dont really mind. Already forgot about the costs
2019-09-23T01:25:49 < BrainDamage> you get extra charges if an amateur driver got in an accident under your supervision
2019-09-23T01:26:36 < Steffanx> And the cars have dual pedal stuff. So not too much can go wrong
2019-09-23T01:26:39 < BrainDamage> but tbh, as long as you're reasonable, it's hard to, also amateur drivers here expose a giant P sign on the back of their cars
2019-09-23T01:27:12 < BrainDamage> so you steer clear / avoid endangering them

2019-09-23T03:58:55 < steve> on the F769 discovery kit, regarding audio output, if I write a square wave to the output buffer and increase the frequency, when it gets past 10khz it becomes a nice sine wave, and then higher than that, ie. toggling the output every sample, no output appears at all.  The only thing I can think of is the RC filter on the codec output (20ohm and 100nF in series, shunted to ground). But even with that I 
2019-09-23T03:59:01 < steve> shouldn't get zero output for a max frequency square wave.  any ideas?

2019-09-23T04:11:53 < Cracki> have you investigated that codec?
2019-09-23T04:12:36 < Cracki> what do you consider "zero output"? what's "max frequency"?

2019-09-23T04:16:37 < steve> anyway, https://pastebin.com/9x6JTkPy  shows how I fill up a buffer with a square wave.  If I increase the frequency any higher, eg. mod 8, there is zero output.  Anything higher than mod 10 works.  I tried this with different sampling frequencies, 22k, 44k, 48k, 96k.  Interestingly, 96k behaves the same way, even though the mod10 square wave is too high to hear.  and again, note that they show up as nice

2019-09-23T04:31:59 < steve> mawk it's in the pastebin
2019-09-23T04:32:02 < Cracki> I would expect him to do his %8 the same way he does his %10
2019-09-23T04:32:17 < Cracki> still, there aren't enough facts here to find the contradiction
2019-09-23T04:32:30 < mawk> it's mod 10 in the pastebin steve 
2019-09-23T04:32:33 < mawk> ah
2019-09-23T04:32:50 < steve> yeah i change 10 to 8 or whatever
2019-09-23T04:32:54 < Cracki> my expectation is entirely unfounded :>
2019-09-23T04:33:07 < mawk> ok, so you reject 5, 6, 7, 8, 9 and you accept 0, 1, 2, 3, 4
2019-09-23T04:33:10 < steve> more interesting, changing to a sine wave like thsi:      buf[i] = 32000.0*arm_sin_f32(2*3.14*i/8.0);
2019-09-23T04:33:17 < mawk> for mod 10, that's a 50% duty cycle
2019-09-23T04:33:32 < Cracki> why is your buf floats, but you don't have them normalized to +-1 but apparently as signed int16?
2019-09-23T04:34:25 < mawk> for mod > 7 your code should kinda work steve 
2019-09-23T04:34:54 < mawk> for mod 8 you accept 6 7 and you reject 0 1 2 3 4 5, that's a 1/3 duty cycle, it shouldn't be all 0s
2019-09-23T04:35:50 < steve> lol, it was implied that you change the 5 to a 4.  eg.  i%10>5 , i%8>4, i%6>3
2019-09-23T04:36:10 < mawk> "whatever" didn't imply that
2019-09-23T04:36:16 < mawk> but alright
2019-09-23T04:36:31 < Cracki> steve, would you share exactly how you determine that the outputs for lower frequencies are good?
2019-09-23T04:36:37 < Cracki> what amplitude, dc offset, etc

2019-09-23T04:37:13 < mawk> lol
2019-09-23T04:37:26 < mawk> for %8 > 4 that's still not not a 50% duty cycle by the way
2019-09-23T04:37:27 < steve> so turns out I can get a higher frequency using the sine wave

2019-09-23T04:37:48 < Cracki> it's a mystery
2019-09-23T04:40:21 < Cracki> why do you use floats, does that codec want them or does it want sint16?
2019-09-23T04:41:08 < Cracki> I'm assuming it uses i2s, so that's integers
2019-09-23T04:41:17 < Cracki> so you fill a buffer with floats there, but then you'd have to convert again
2019-09-23T04:41:36 < Cracki> I'm guessing the problem is in a place you haven't shown yet
2019-09-23T04:41:58  * Cracki needs to start running a meter and billing people

2019-09-23T04:42:24 < Cracki> watching louis rossmann videos, and how he has to deal with yelp trolls, is heartbreaking
2019-09-23T04:42:42 < Cracki> the world would be a better place if he had a trap door and fire pit to drop people into
2019-09-23T04:43:11 < Cracki> I hope the new place has a nice street side trapdoor they can use
2019-09-23T04:43:18 < steve> ok here it is:  so a 2pi*n/16 sine wave is 24kHz, amplitude 1V as expected.  And then 2pi*n/8 is much less amplitude, like 200mV.  So it makes sense that going any higher than that will appear as zero
2019-09-23T04:43:42 < Cracki> see, what's what I was worried about
2019-09-23T04:43:59 < steve> so it must be that RC shunt on the codec output, or some internal anti aliasing in the codec, but I searched for "
2019-09-23T04:44:05 < steve> "alias" in the codec datasheeet, dosen't appear
2019-09-23T04:44:11 < steve> both "alias" and "filter"
2019-09-23T04:44:35 < Cracki> 2pin/16 is 24 khz?
2019-09-23T04:44:39 < Cracki> 2pi/8 is 48 khz
2019-09-23T04:44:51 < Cracki> that's already at nyquist limit for a 96 khz DAC
2019-09-23T04:45:14 < Cracki> so I would very much expect this to drop off by 3 dB right there
2019-09-23T04:45:26 < Cracki> needn't, but would be within sane design goals
2019-09-23T04:45:42 < Cracki> did you expect to get anything above 48 khz out of a 96 khz codec?
2019-09-23T04:45:51 < steve> why would you expect that?  from a anti aliasing filter?
2019-09-23T04:45:58 < Cracki> no, from simple performance goals
2019-09-23T04:46:24 < Cracki> the rc lowpass was way above that so it makes no noticeable dent ehre
2019-09-23T04:46:46 < steve> which RC?  did you check the schematic?
2019-09-23T04:46:57 < Cracki> is the codec 96 khz sampling?
2019-09-23T04:47:23 < steve> yes
2019-09-23T04:47:42 < Cracki> then, by nyquist, you get at most 48 khz out of it
2019-09-23T04:47:54 < Cracki> because one sine wave needs at least two samples
2019-09-23T04:48:22 < Cracki> go above, you get aliasing that looks like mirroring: 49 khz comes out as 47 khz and so on
2019-09-23T04:48:34 < Cracki> 47 khz and 1 khz even, I think
2019-09-23T04:49:11 < Cracki> anyway, you saw that amplitude drops, and not at all suddenly
2019-09-23T04:49:15 < steve> you're confusing sampling and DACs
2019-09-23T04:49:30 < steve> a 96kHz DAC can output a square wave of 48kHz
2019-09-23T04:49:32 < Cracki> merely the words
2019-09-23T04:49:38 < Cracki> and that's exactly what I said
2019-09-23T04:49:50 < Cracki> and you got 0.2V at 48 khz
2019-09-23T04:50:05 < Cracki> that's -2.3 dB
2019-09-23T04:50:09 < steve> there's no reason why a 96kHz DAC can't show a nice 48kHz square wave.  I guess it's due to the RC filter
2019-09-23T04:50:50 < Cracki> perhaps, but that rc's values wouldn't have that effect so early
2019-09-23T04:51:08 < steve> which RC are you talking about?  the schematic shows 20ohm and 100nF
2019-09-23T04:51:28 < Cracki> that
2019-09-23T04:52:06 < Cracki> 80 khz cutoff frequency
2019-09-23T04:52:07 < steve> yep, I believe that is it.
2019-09-23T04:52:16 < Cracki> and cutoff usually means -3 dB
2019-09-23T04:52:21 < steve> how do you get 80kHz?
2019-09-23T04:52:22 < Cracki> and we're still some distance away from that
2019-09-23T04:52:29 < Cracki> 1 / (2 pi R C)
2019-09-23T04:52:55 < steve> hmm that's a regular RC filter, this is an RC shunt.  are you sure it's the same formula?
2019-09-23T04:53:21 < Cracki> I don't even have the schematic open
2019-09-23T04:53:38 < Cracki> you want me to see something, link it :P
2019-09-23T04:54:22 < Cracki> I see the schematic
2019-09-23T04:54:24 < Cracki> looks odd
2019-09-23T04:54:50 < Cracki> dump it into falstad and simulate?
2019-09-23T04:54:52 < steve> I like what this says:  https://keisan.casio.com/exec/system/1258032632  , it says 80 ohms at 20kHz, 1500 ohms at 1kHz
2019-09-23T04:59:57 < steve> well I'll say case closed.  hope you learned something Cracki, Mr. "i should charge for my time and I chat like a 12 year old" :P
2019-09-23T05:00:26 < Cracki> and what's that
2019-09-23T05:00:43 < Cracki> what did you learn?
2019-09-23T05:03:25 < Cracki> great, now I need to teach my script to check nickserv identification...

2019-09-23T14:00:16 < karlp> BrainDamage: what is "T and S parking" ?
2019-09-23T14:05:07 < BrainDamage> it's how the common ways to park are called here, it's the pattern of the movement that the car makes when you pull in in reverse to park, the first one when the parking lot is orthogonal compared to the road, the second when it's parallel
2019-09-23T14:06:36 < karlp> gotcha
2019-09-23T14:11:26 < antto> i think i did a T kind of parking today
2019-09-23T14:12:07 < antto> how do you say kaufland in dongsish dialect?
2019-09-23T14:15:18 < BrainDamage> wrt the square wave, you need to include at least 2-3 harmonics in order to see something 'square like'
2019-09-23T14:15:37 -!- Sadale [~Sadale@unaffiliated/sadale] has joined ##stm32
2019-09-23T14:15:39 < BrainDamage> and a squarewave has only odd harmonics, which means 1st, 3rd, 5th etc of the fundamental
2019-09-23T14:15:44 < karlp> kaufland is a proper noun, there's no translation required....
2019-09-23T14:16:03 < antto> o_O i can't believe this
2019-09-23T14:16:16 < BrainDamage> so in order to see a square you need at least 5x the bandwith 
2019-09-23T14:16:17 < karlp> you should probably capitalize it though....
2019-09-23T14:16:38 < karlp> (if you _meant_ kaufland the store, not a generic big grocery or something)

2019-09-23T15:58:20 < mawk> I don't understand BrainDamage , you're saying this for an ADC right ?
2019-09-23T15:59:05 < mawk> if it's for a DAC you don't feed it with fourier coefficients, you feed it with the values you want to see; even with that you can't do a square wave without 5f bandwidth ?
2019-09-23T16:08:58 < dongs> there's a 8pin G0?
2019-09-23T16:09:32 < mawk> yes
2019-09-23T16:09:35 < dongs> cool
2019-09-23T16:09:37 < mawk> stm32g030j6
2019-09-23T16:10:21 < mawk> but they say no availability from distributors
2019-09-23T16:10:23 < mawk> too new maybe
2019-09-23T16:10:31 < mawk> "please contact our sales office"
2019-09-23T16:35:15 < BrainDamage> mawk: you feed a time signal, and yes, nyquist's theorem is actually not about sampling but about *reconstruction*
2019-09-23T16:38:22 < BrainDamage> the output signal is the input signal which is a train of dirac deltas, scaled, and then filtered by a lowpass filter to cut off the higher repetitions but the 1st
2019-09-23T16:38:52 < BrainDamage> ( this is not 100% correct because a real dac uses a zero-order hold which slightly distorts ), but it doesn't change the reasoning
2019-09-23T16:39:30 < mawk> ah
2019-09-23T16:39:37 < mawk> ok I see
2019-09-23T16:39:37 < BrainDamage> the lowpass filter is called a reconstruction filter, and it's 100% necessary for the dac to work
2019-09-23T16:40:08 < mawk> yeah
2019-09-23T16:40:27 < mawk> because otherwise the sum of diracs is a sum of shifted copies of the signal
2019-09-23T16:40:40 < mawk> and we want the first

2019-09-23T16:42:32 < BrainDamage> so once your square goes into the reconstruction filter, all that's left is the fundamental
2019-09-23T16:42:43 < BrainDamage> so you get a sine @ the output
2019-09-23T16:43:18 -!- fenugrec [~fenugrec@24.105.71.66] has joined ##stm32
2019-09-23T16:43:33 < mawk> so that's why you need to feed the "imperfect" square 
2019-09-23T16:43:39 < mawk> as a sum of its first harmonics
2019-09-23T16:44:17 < karlp> are you guys saying that if I feed 0,4096,0,4096 to the stm32 dac I won't get a "square" (with slopy edges defined by the dac's slew rates) at all?
2019-09-23T16:44:39 < BrainDamage> if you have a proper lowpass filter at the output, you'll get a sine
2019-09-23T16:44:53 < BrainDamage> if you don't, then there's the lowpass filter from slew rate, etc
2019-09-23T16:45:21 < BrainDamage> which will still chop higher armonics, but not as much as what a normal dac should have for analog reconstruction
2019-09-23T16:45:45 < mawk> but if the square is low frequency enough you won't get a perfect sine, you will get a square looking thing ?
2019-09-23T16:46:10 < BrainDamage> yes, the more harmonics fit into your filter's bandwith, the more square it'll look
2019-09-23T16:46:12 < mawk> if like the first 5 harmonics are below the cutoff frequency
2019-09-23T16:46:16 < mawk> alright
2019-09-23T16:46:20 < nuxil> karlp, 12 bit. its 4095 max 0-4095 = 4096 stps.
2019-09-23T16:46:42 < nuxil> not 4096 :p
2019-09-23T16:47:51 < nuxil> 4096 will probably overflow. so no it will not be a squar :p
2019-09-23T16:48:15 < Ultrasauce> it will be a perfect square wave with amplitude 0
2019-09-23T16:49:03 < karlp> nuxil: whatevs man. :)
2019-09-23T16:50:02 < nuxil> ^^
2019-09-23T16:50:13 < BrainDamage> oh and his case of shunt filtering, the filter's cutoff depends on whatever's impedance is attached to
2019-09-23T16:50:29 < BrainDamage> so it's not clear what freq it started kicking in

2019-09-23T17:12:47 < mawk> I believe he just misread the schematic and it was a regular RC filter no ?
2019-09-23T17:16:43 < zyp> wouldn't any unbuffered filter be affected by the load impedance?
2019-09-23T17:16:57 < mawk> yeah
2019-09-23T17:17:09 < mawk> if it's not buffered and the load isn't very high impedance the voltage will just collapse
2019-09-23T17:17:25 < mawk> depending on the DAC construction I guess
2019-09-23T17:37:00 < BrainDamage> not just the partition, the pole will shift too
2019-09-23T17:37:23 < BrainDamage> because the pole will be (Rfilt + (Rin//Rout)0 * C
2019-09-23T17:37:46 < BrainDamage> while the zero will remain the same at Rfilt * C
2019-09-23T17:38:58 < BrainDamage> so the transfer function will look like a backward -\_ with a lower ceiling when the zero kicks in
2019-09-23T17:39:11 < BrainDamage> err, ditch the backwards
2019-09-23T17:39:34 < BrainDamage> as in, in high freq case, it'll just be a voltage divider

2019-09-24T03:26:48 < Cracki> >triggered
2019-09-24T03:30:22 < jadew`> yesterday I asked about some inventory management tools
2019-09-24T03:30:47 < jadew`> found one that I think has spyware in it or something fishy
2019-09-24T03:30:57 < jadew`> every couple of seconds it has network activity
2019-09-24T03:34:09 < jadew`> I ended up improvising something
2019-09-24T03:34:33 < jadew`> it's still work in progress, but at least I know how much of something I should have

2019-09-24T03:54:45 < Cracki> the world is full of tradeoffs.
2019-09-24T03:55:27 < Cracki> NIH/bespoke costs. off the shelf doesn't fit perfectly. something in the middle... eh.
2019-09-24T03:55:46 < BrainDamage> my major problem with inventory software is my own lazyness in using it
2019-09-24T03:56:21 < jadew`> yeah, same here, but it's good enough for ballpark figures
2019-09-24T03:56:54 < Laurenceb_> keek Musk is messaging his autistic Latina thot hareem
2019-09-24T03:57:01 < Cracki> you can always go wilder. I am doing my (sugary fizzy drinks) with google shits. I could automate the inventory taking (sensors, computer vision, ...)
2019-09-24T03:57:02 < jadew`> with my little db, I now know how many of something I ever ordered
2019-09-24T03:57:10 < Laurenceb_> hes got Martian population sorted
2019-09-24T03:57:49 < Laurenceb_> make Mars Mexico again
2019-09-24T03:57:50 < jadew`> so if I see that I got 500 resistors of one kind and I know I only used ~100 in production, odds are I still have enough, so I don't have to buy them again
2019-09-24T03:58:56 < Cracki> >input: 4.2 meters of empty tape
2019-09-24T03:58:57 < Laurenceb_> inb4 he loads the cargo bay with Latina thots and it blows up
2019-09-24T04:01:15 < Cracki> look up some 90s/2ks pop music on yt. lots of girls dancing to it.
2019-09-24T04:01:55 < jadew`> like this? https://www.youtube.com/watch?v=IM-ky0uLFbI
2019-09-24T04:01:55 < Cracki> I wonder what I have to search to get cute guys dancing like that
2019-09-24T04:02:04 < jadew`> Cracki, that ^
2019-09-24T04:02:23 < Cracki> mixed bag
2019-09-24T04:02:26 < jadew`> yeah
2019-09-24T04:02:29 < Laurenceb_> Cracki: Shia dancing
2019-09-24T04:02:31 < jadew`> lots of guys doing shuffle dancing
2019-09-24T04:02:33  * Cracki hits > to get 1.25x
2019-09-24T04:02:56 < Cracki> this but guys pls https://www.youtube.com/watch?v=QQSYo_pC-QA
2019-09-24T04:03:29 < jadew`> I watched that earlier today
2019-09-24T04:03:34 < jadew`> it's in my daily playlist
2019-09-24T04:03:38 < Cracki> I'm spoiled. I can't watch most music at 1.0x
2019-09-24T04:04:08 < Cracki> the resonators in my skull must be speshul
2019-09-24T04:04:49 < Cracki> I wish there were some prof who could supervise what I'd really like to do: work a little on temporal speech compression
2019-09-24T04:05:35 < Laurenceb_> https://www.youtube.com/watch?v=mbUDLZ5zpIM
2019-09-24T04:05:40 < jadew`> increase sample rate and reduce pitch?
2019-09-24T04:05:48 < Cracki> watno
2019-09-24T04:05:58 < Cracki> chrome et al already have pitch maintaining time stretch
2019-09-24T04:06:03 < Cracki> but that's linear.
2019-09-24T04:06:43 < jadew`> sorry, decrease sample rate and reduce pitch
2019-09-24T04:06:52 < Cracki> speech isn't. you can squeeze pauses a lot for some speakers. further improvement by re-articulating phonemes. think handwriting but fucking with the strokes so they look a lot more intelligible, yet still your handwriting
2019-09-24T04:07:26 < jadew`> that would be cool
2019-09-24T04:07:30 < jadew`> my videos suffer from that
2019-09-24T04:07:42 < Cracki> the usual algorithms take windows and slide them into each other like reptile scales, with some wiggle room for best correlation
2019-09-24T04:07:52 < jadew`> I could use some software that makes me sound normal
2019-09-24T04:08:08 < Cracki> if two adjacent windows, and only those, contain vital phonemes, and they get mixed together, you lose info
2019-09-24T04:08:19 < BrainDamage> I'm going to quote you out of context with that
2019-09-24T04:08:28 < Cracki> low amplitude phonemes suffer too, if they get "sat on" by louder neighbors
2019-09-24T04:08:29 < jadew`> lol
2019-09-24T04:09:00 < Cracki> me? try. I'm curious what I said there that could have any particular effect when quoted ooc
2019-09-24T04:09:32 < jadew`> it's what I said
2019-09-24T04:09:40 < Cracki> if you want something that makes you sound "normal", I'm sure deep learning can do something like that already
2019-09-24T04:10:45 < Cracki> what I wonder is how much effort it would be to learn to understand unnatural voices. we can learn to distinguish animal sounds. those have totally different voice boxes.
2019-09-24T04:11:33 < Cracki> I'm thinking, take human speech, analyze, transform/rearrange (frequency shift?). like taking a flat parking lot and stacking it up into a multi-level garage
2019-09-24T04:11:44 < BrainDamage> https://github.com/CorentinJ/Real-Time-Voice-Cloning
2019-09-24T04:11:56 < BrainDamage> feed in dave samples
2019-09-24T04:12:41 < jadew`> jeez, that's great
2019-09-24T04:15:01 < Cracki> apropos ds9, they had one episode where they used holotech to fake video footage
2019-09-24T04:15:53 < Cracki> part of that iirc was automatic translation that hid nuances in the speaker's words
2019-09-24T04:17:07 < Laurenceb_> anyone here ever used Elmer multiphysics?
2019-09-24T04:17:08 < Cracki> it isn't much further until you can have DL do realtime translations. there are networks that understand text upto literal world building (it seems to have imagination)
2019-09-24T04:17:20 < BrainDamage> 3 years ago
2019-09-24T04:17:23 < BrainDamage> it was a mess
2019-09-24T04:17:43 < Laurenceb_> yeah I only got NaN from the solver
2019-09-24T04:17:55 < Laurenceb_> but that was a while ago
2019-09-24T04:18:03 < BrainDamage> what are you using to generate your meshes?
2019-09-24T04:18:05 < BrainDamage> gmsh?
2019-09-24T04:18:06 < Laurenceb_> I'm thinking of using it for the space runway
2019-09-24T04:18:09 < Laurenceb_> yeah iirc
2019-09-24T04:18:18 < Laurenceb_> havent tried anything yet
2019-09-24T04:18:44 < Laurenceb_> the runway thing is really complex,but I found some examples of all the constituent things I need...
2019-09-24T04:18:58 < Laurenceb_> I need runtime remeshing and moving submeshes
2019-09-24T04:19:08 < BrainDamage> or pirate comsol >.>
2019-09-24T04:19:37 < Laurenceb_> yeah
2019-09-24T04:19:54 < Laurenceb_> this is taking multiphysics to the limit
2019-09-24T04:20:34 < Cracki> so long as you don't need relativity or quantum physics
2019-09-24T04:20:48 < Laurenceb_> yeah
2019-09-24T04:21:22 < Laurenceb_> just spacecraft at 6km/s with 1T field moving inside a metal foil tube that gets distorted by it
2019-09-24T04:21:33 < Laurenceb_> all interacting
2019-09-24T04:21:45 < Cracki> lotsa finite elements
2019-09-24T04:22:33 < Laurenceb_> hopefully not NaN or Inf elements
2019-09-24T04:22:50 < mawk> you've got a bunch of symmetries here Laurenceb_ right
2019-09-24T04:23:09 < mawk> ship is a simple sphere, tube is infinite cylinder
2019-09-24T04:23:27 < mawk> no need for meshes
2019-09-24T04:23:34 < mawk> nobody will verify your work anyway
2019-09-24T04:23:34 < Laurenceb_> yeah there are algebraic solutions to that situation
2019-09-24T04:23:39 < mawk> nice
2019-09-24T04:24:32 < Laurenceb_> I want to look at asymmetric ship entry
2019-09-24T04:24:58 < Laurenceb_> which rapidly gets really complex
2019-09-24T04:25:38 < BrainDamage> I imagine there's going to be a bunch of weird shit on the transition to the mag field
2019-09-24T04:26:14 < BrainDamage> normally mag brakes are somewhat negligible in size compared to the whole thing
2019-09-24T04:26:30 < BrainDamage> here the whole hull would get eddy currents
2019-09-24T04:27:13 < Laurenceb_> yeah it all gets pretty weird
2019-09-24T04:27:23 < BrainDamage> if you add the heating from drag and the currents, then it'll be `fun`
2019-09-24T04:27:31 < Laurenceb_> everything is interacting with everything else so it all needs to go into the multiphysics
2019-09-24T04:27:37  * Laurenceb_ zzz
2019-09-24T04:29:01 < Cracki> does it simulate shit melting?
2019-09-24T04:29:28 < Cracki> lattice structures breaking up? material weakening? :D
2019-09-24T04:29:47 < BrainDamage> it does mechanical deformations
2019-09-24T04:30:05 < BrainDamage> but I'm not sure if it has a model of temp weakening

2019-09-24T12:26:10 < dongs> why the shit are you shopping for resistors at mouser
2019-09-24T12:34:50 < zyp> he couldn't resist
2019-09-24T12:36:31 < dongs> literally that
2019-09-24T12:36:40 < dongs> i mean, china reel is $3 for a reel of 0402
2019-09-24T12:36:49 < dongs> you're lucky to get 100 resistors on cut tape for $3 from mouser
2019-09-24T12:37:55 < dongs> my china cut tape comes in super fancy ziplock bag with a label too
2019-09-24T12:45:27 < rajkosto> will RTV silicone hold together a metal plate and acrylic plate

2019-09-24T12:48:09 < qyx> china reels would be in a week in the better option if they was not being stuck at customs
2019-09-24T12:48:54 < qyx> ok, I lie, few days
2019-09-24T12:48:58 < qyx> farnell would be tomorrow

2019-09-24T13:06:12 < specing> Well, not sure if farnell does that or not, but arrow sorted by qty 1000+ price
2019-09-24T13:06:37 < specing> I like LCSC, their pricing seems deterministic

2019-09-24T14:31:14 < roomba> it's one of the cheap ones but not as bad as the _other_ cheap ones.
2019-09-24T14:31:32 < roomba> works as advertised, which surprised me.
2019-09-24T14:31:41 < roomba> however. i noticed something interesting about it.
2019-09-24T14:31:53 < roomba> on the bottom, there is a slide switch for power.
2019-09-24T14:32:26 < roomba> when it's turned off, it leeches power like crazy. battery drains after about a week.
2019-09-24T14:32:53 < roomba> i wonder if maybe that switch turns off the backlight only?
2019-09-24T14:33:38 < roomba> or maybe it's the battery itself? never had a device that had this behavior.

2019-09-24T14:38:15 < englishman> dongs: yeah
2019-09-24T14:38:32 < Cracki> must be the heating switch. I see no other reason for it to "leech power like crazy"
2019-09-24T14:38:44 < englishman> dongs: should i install 1903 or wait for 1909
2019-09-24T14:39:41 < roomba> Cracki: me neither. but it does. going to take it apart one of these days and try to learn why.
2019-09-24T14:39:58 < Cracki> does it have memory
2019-09-24T14:40:08 < Cracki> does it retain memory while off
2019-09-24T14:40:22 < Cracki> does that switch affect that maybe

2019-09-24T14:44:37 < Cracki> do car mechanics actually do that or is that just engineers trying to make their less braincellishly gifted cousins in trade?

2019-09-24T14:46:07 < Cracki> I watch yt videos of a dude doing "property maintenance" with "heavy" machinery. digging dirt, spreading dirt, cutting trees

2019-09-24T14:46:56 < Cracki> he has a golden retriever. adorable.
2019-09-24T14:47:11 < Cracki> also the drone footage is excellent
2019-09-24T14:47:28 < Cracki> good stabilization is worth it
2019-09-24T14:47:47 < Cracki> same with louis rossmann's nyc realtor non-hidden camera
2019-09-24T14:49:10 < Cracki> smartphones these days have multiple cameras and depth sensing too. there must be an app for SLAM, scan rooms like a hololens and measure them
2019-09-24T14:49:45 < roomba> did you see rossman own that real estate lady with one of those bosch sq ft. measuring devices?
2019-09-24T14:50:59 < Cracki> I am following closely
2019-09-24T14:51:09 < qyx> Cracki: thats my dream job
2019-09-24T14:51:20 < Cracki> I'm sure she was just "following orders", i.e. post this number and those words
2019-09-24T14:52:03 < Cracki> and the 1800sf were including basement, but as he said, that's all bullshit because the price is for just the shop floor
2019-09-24T14:52:40 < Cracki> their weird pricing... dollars per sqft is per year, but dollars per area is per month
2019-09-24T14:53:33 < qyx> his john deere is nearly ded
2019-09-24T14:53:41 < Cracki> and then I saw number for $/sqft that are around 1000 rather than 100 or 70 is what he finds fair. must be extremely flexible (assraepy) there.
2019-09-24T14:54:03 < roomba> yeah. they price it to what the market will withstand and then try to justify it with broken math
2019-09-24T14:54:06 < Cracki> don't delay, build your container castle today
2019-09-24T14:54:53 < Cracki> in a market, your price never needs justification except for "demand outstrips supply ¯\_(ツ)_/¯"
2019-09-24T14:55:05 < Cracki> ergo, it's not a market, it's usury or something
2019-09-24T14:55:19 < Cracki> prices are falling. they all just haven't realized.

2019-09-24T14:59:17 < roomba> and two houses soon to be mine, which i'll spin into a couple more houses when the next recession hits and the prices go down.
2019-09-24T14:59:25 < roomba> to convert into more rentals
2019-09-24T14:59:26 < Cracki> nice
2019-09-24T14:59:44 < Cracki> sounds successful enough :P
2019-09-24T14:59:52 < roomba> barely lol.
2019-09-24T15:00:14 < roomba> i helped get the two we have now but they barely break even.
2019-09-24T15:00:35 < roomba> property taxes are insane on one of them
2019-09-24T15:01:18 < roomba> the one i live in was under $30k coming out of the last recession
2019-09-24T15:01:46 < roomba> 2 story + basement + 3 br + 2 bath. backyard.
2019-09-24T15:03:21 < roomba> houses are the way to go when times get rough. especially in rural areas. sooooo cheap. and then when things get better, you're sitting on >$100k in equity.
2019-09-24T15:05:19 < Cracki> surely those living there don't make the demand ebb and flow, so what does? city rats?
2019-09-24T15:07:01 < roomba> demand goes away because economy gets bad
2019-09-24T15:07:12 < roomba> foreclosures
2019-09-24T15:11:06 < qyx> roomba: wuth $30k for a house
2019-09-24T15:12:10 < roomba> the one i'm in now was $30k. the one my sister is in was $40k.

2019-09-24T15:44:19 < roomba> lol gdpr
2019-09-24T15:45:28 < roomba> far enough away from a city to make it economically impractical to work there, close enough to not be in the middle of nowhere
2019-09-24T15:45:49 < roomba> let's just say if you wanna go grocery shopping around here, you make a day out of it.
2019-09-24T15:46:05 < qyx> I am asking because it is very hard to buy such house here for that price
2019-09-24T15:46:10 < qyx> and thats middle-east eu

2019-09-24T15:49:50 < roomba> yea
2019-09-24T15:50:00 < roomba> the contrast is sharp
2019-09-24T15:50:50 < roomba> you're either in the city eating avocado croutons and paying 50%+ of your income on rent or you're in fentanylville with super cheap living costs and no jobs.
2019-09-24T15:51:25 < Cracki> the closest you get to feeling "murican" in europe is driving through agricultural areas. europe doesn't have those vast woods anymore.
2019-09-24T15:51:55 < Cracki> nvm, it's really just distances.
2019-09-24T15:52:47 < roomba> lol you don't know what corn fields are until you drive through iowa
2019-09-24T15:53:39 < roomba> they're massive
2019-09-24T15:53:55 < Cracki> :)
2019-09-24T15:54:02 < roomba> it's like going to see the ocean... but it's corn.
2019-09-24T15:55:10 < Cracki> those big combines were invented in america because you have the vast flat spaces there. not so in europe. here we develop steel-studded rubber wheels so you can drive your mower on 100% slopes
2019-09-24T15:55:44 < qyx> heh
2019-09-24T15:55:57 < roomba> dude those combines are so big. have you ever seen one irl?
2019-09-24T15:56:00 < zyp> I like the term «going to see the ocean»
2019-09-24T15:56:18 < zyp> to me, the ocean has always been right outside, not something you'd have to go see
2019-09-24T15:56:25 < Cracki> never irl. I know they've been growing to 15-20 meters/yards now
2019-09-24T15:56:53 < Cracki> if you live 5 km off the coast, going to see the ocean is a bike ride
2019-09-24T15:57:04 < Cracki> if you live 500 km off the coast, you go on youtube
2019-09-24T15:57:46 < qyx> it is like saying going to climb some 2000m+ mountain
2019-09-24T15:58:03 < Cracki> I live in a place where they call an asphalt road "gracht" (which is supposed to be a waterway) and the widest "river" is something you can jump over and nobody ever drowned in

2019-09-24T18:02:37 < jadew`> so... it turns out that you can't ditch the paypal conversion fees
2019-09-24T18:03:11 < jadew`> it's set up in such a way, that it's not flexible with the currency
2019-09-24T18:03:27 < jadew`> I can't withdraw GBP for example
2019-09-24T18:03:52 < jadew`> I have to convert it on their platform and withdraw RON or EUR
2019-09-24T18:04:09 < jadew`> if you were based in the US, you could only withdraw USD
2019-09-24T18:05:22 < jadew`> and while it can withdraw to a VISA card in a different currency, all these new online banking things that offer great currency conversion offer only mastercard :)
2019-09-24T18:10:54 < englishman> yeah to do transactions in USD i use a USD account in my canadian bank and use USA routing info
2019-09-24T18:11:15 < englishman> i dont think they do foreign currency transactions to banks at all
2019-09-24T18:11:44 < jadew`> yeah, that's what it looks like
2019-09-24T18:14:05 < BrainDamage> in the past, at least when paying, you had the option if to chose to do conversion or not
2019-09-24T18:14:13 < BrainDamage> it was pretty hidden, but was there
2019-09-24T18:14:17 < BrainDamage> not sure now
2019-09-24T18:19:38 < jadew`> now too, but for withdrawal it's not possible

2019-09-24T23:22:45 < zyp> and there's also a couple meters of city-owned land between my yard and my neighbor's yard
2019-09-24T23:23:17 < englishman> zyp, did you finance your egolf
2019-09-24T23:23:45 < zyp> yes, is by finance you mean got a loan to buy it
2019-09-24T23:23:48 < zyp> if*
2019-09-24T23:24:00 < englishman> that is exactly what i meant
2019-09-24T23:24:04 < englishman> what was the interest rate?
2019-09-24T23:24:44 < zyp> at the moment it's 5.85% p.a. effective
2019-09-24T23:24:51 < zyp> it's been changing a bit
2019-09-24T23:24:54 < englishman> really
2019-09-24T23:25:18 < zyp> but still, car loans here are usually around there
2019-09-24T23:26:08 < englishman> good to know thanks
2019-09-24T23:26:17 < zyp> why?
2019-09-24T23:26:51 < englishman> i got offered 3.3% and was wondering if it was any good
2019-09-24T23:27:31 < englishman> in dollar value it seemed ok, it would cost me x to borrow y and i was ok with that amount
2019-09-24T23:28:09 < zyp> I think the dealership had an offer for a better rate, but that one required me to put down a significant amount
2019-09-24T23:28:43 < zyp> and I could basically pick between that and a free set of snow tires, so I went with the latter and got a loan from my bank
2019-09-24T23:29:09 < zyp> for 100% financed
2019-09-24T23:29:23 < englishman> 100% wow
2019-09-24T23:30:23 < zyp> well, yeah, I bought the car shortly after getting a job after having been unemployed for a while

2019-09-25T00:16:35 < jadew`> wth...
2019-09-25T00:16:43 < zyp> not sure how well it works in practice

2019-09-25T00:17:40 < zyp> I think there's some crypto involved, idk
2019-09-25T00:18:15 < qyx> yes, that hpna has aes128 and you have to pair them
2019-09-25T00:18:17 < kakimir32> speed penalty
2019-09-25T00:18:23 < qyx> also it cannot travel across inductors

2019-09-25T00:18:34 < qyx> so it is probably blocked by the power meter

2019-09-25T01:04:15 < kakimir32> *none of them were of any use* ?
2019-09-25T01:06:16 < zyp> I thought modern browsers already stored tabs well enough

2019-09-25T01:36:39 < catphish> i just ordered some av2 (tp-link 2 gigabit version), will how it fares, had mixed results with the previous generation
2019-09-25T01:37:25 < kakimir32> with wifi ap?
2019-09-25T01:37:34 < kakimir32> or just wired
2019-09-25T01:38:11 < catphish> just wired, actually i really can't figure out how best to wire up my house
2019-09-25T01:38:22 < catphish> but got a pair of the wired ones cheap so thought i'd test
2019-09-25T01:39:34 < catphish> if it's good enough i might buy several wifi eqipped ones, or just have a couple with unifis discretely plugged in
2019-09-25T01:40:31 < catphish> i just ripped out all my surface mount cabling to redecorate
2019-09-25T01:41:20 < kakimir32> those are cheap
2019-09-25T01:41:24 < kakimir32> and work
2019-09-25T01:41:32 < kakimir32> just works
2019-09-25T01:42:39 < catphish> what are?
2019-09-25T01:44:44 < kakimir32> just wired homeplug av2 bricks
2019-09-25T01:44:49 < kakimir32> tp-link
2019-09-25T01:45:37 < catphish> i wasn't sure whether to make the jump to the wifi ones, would be super neat to insall
2019-09-25T01:46:11 < kakimir32> additional price is not much
2019-09-25T01:46:21 < kakimir32> but those are usually just 802.11N
2019-09-25T01:46:37 < kakimir32> which is meeeh!
2019-09-25T01:47:59 < catphish> this is the one i want https://www.tp-link.com/uk/home-networking/powerline/tl-wpa9610-kit/
2019-09-25T01:48:00 < kakimir32> I mean pair of bricks is like 40-50eur or so and throw 20eur more at it and you have pair with another brick featuring 802.11n
2019-09-25T01:48:39 < kakimir32> oh
2019-09-25T01:48:40 < kakimir32> AC
2019-09-25T01:48:48 < catphish> 2Gbps powerline + 11ac

2019-09-25T01:51:28 < catphish> but seems a downgrade from my unifi-ac-lr
2019-09-25T01:56:49 < kakimir32> it is
2019-09-25T01:57:31 < kakimir32> indeed
2019-09-25T01:58:54 < catphish> i'll stick with unifi then, one where my router is, and then i'll use the av2000 wired devices to put a second one at the other end of the house, should be plenty
2019-09-25T01:59:21 < catphish> even if the powerline sucks, all my main areas are in range of he primary one :)
2019-09-25T02:01:15 < catphish> i paid £45 for the pair of wired "av2000"bricks, hopefully they're good
2019-09-25T02:16:23 < kakimir32> do you have single phase home electric system in uk?

2019-09-25T04:10:03 < roomba> Cracki: nope
2019-09-25T04:23:22 < specing> maybe its a european-sized stove, like, real tiny

2019-09-25T09:12:20 < R2COM> also stupid default code for some reason assumes "normal" state for init structure, and if thats the case it never calls MSP function

2019-09-25T12:58:32 < BrainDamage> the EU is/was part of this
2019-09-25T12:58:43 < BrainDamage> free trade zone means similar economical policies

2019-09-25T13:00:24 < BrainDamage> customs as entity makes sense to maintain some degree of protectionism, then ofc the actual implementation can contain a ton of silly bullshit

2019-09-25T13:02:08 < jadew`> they don't even open most packages, so it's not like they check the insides
2019-09-25T13:02:59 < BrainDamage> many countries have some part of their economy where they cannot feasibly compete with others, yet they want to maintain in order to keep some independence / reduce external influence
2019-09-25T13:03:21 < BrainDamage> eg milk production in northern countries is considerably harder than in souther
2019-09-25T13:03:57 < jadew`> BrainDamage, right, that would make sense, except china is destroying electronic manufacturing in the EU and nothing is done about it
2019-09-25T13:03:57 < BrainDamage> customs block everything, but then will be lax with a cathegory of goods that are likely to not impact it
2019-09-25T13:04:32 < BrainDamage> yes, we're selling out in order to keep our current lifestyle
2019-09-25T13:05:18 < BrainDamage> protectionism comes at the cost of being uncompetitive and slowing down development
2019-09-25T13:06:17 < BrainDamage> the EU gets away in the internal market by imposing hard limits on production and inflict sanctions
2019-09-25T13:06:44 < BrainDamage> italy got hit many times with sanctions because our factories were simply producing too much, crippling northern
2019-09-25T13:06:50 < BrainDamage> this created a lot of social unrest
2019-09-25T13:07:06 < jadew`> yeah, they did that here too
2019-09-25T13:07:14 < BrainDamage> I'm pretty sure a similar situation happened in the north for other goods
2019-09-25T13:07:15 < jadew`> they basically killed entire industries
2019-09-25T13:07:28 < karlp> you want to go back to how it was before?
2019-09-25T13:07:46 < jadew`> karlp, for me it would be bad
2019-09-25T13:07:56 < jadew`> I benefit from the free trade
2019-09-25T13:07:58 < karlp> this is better, and some of those industries probably deserved to be killed off.
2019-09-25T13:08:04 < BrainDamage> no, at least for italy, it'd be an extremely stupid thing
2019-09-25T13:08:23 < BrainDamage> we live off exported goods and have little prime materials
2019-09-25T13:08:23 < karlp> BrainDamage: I know, I wasn't really expecting anyone to say they did want to go back :)
2019-09-25T13:09:03 < BrainDamage> there's people here who actually say they want to leave eu because they focus on the restrictions rather than see them in balance with the benefits
2019-09-25T13:09:34 < jadew`> that's probably because they're more affected by the restrictions than the benefits
2019-09-25T13:09:54 < jadew`> or that's how they see it
2019-09-25T13:10:18 < karlp> sometimes, (here) it seems that it's more they want to be able to do things privately, without bid, rather than being "restricted" by eu fair competition and transparency...
2019-09-25T13:10:45 < karlp> they want all the benefits of the single market, but don't actualyl want anyone to come here and outcompete them in that single market...
2019-09-25T13:11:24 < karlp> ZOMG someone with a name that isn't icelandic might be a better farmer than someone with the right spelling of their name?!?!?!! we MUST BAN THIS MONSTROUS DEVELOPMENT!
2019-09-25T13:11:47 < karlp> stupid ranty politications
2019-09-25T13:11:55 < jadew`> right, we had that here too with software companies, complaining they can't compete for developers because external companies, that settle here, are paying them more

2019-09-25T13:12:51 < BrainDamage> people just need to realize that now the scope of the movement is EU wide instead of country wide

2019-09-25T13:13:04 < Cracki> I'd trust markets for that more than some government acting for special interest groups. this is far away from free-market cartels and monopolies.
2019-09-25T13:13:42 < karlp> BrainDamage: yeah, I think more poeple are realizing it, but it's a change for some people still :)
2019-09-25T13:13:45 < BrainDamage> you can only do that when the market starts on an even ground
2019-09-25T13:13:53 < BrainDamage> which is simply impossible
2019-09-25T13:13:59  * karlp loves eu mobile roaming
2019-09-25T13:14:22 < Cracki> simple mass PCBA in china is a good idea. if you need one-offs or special specifications, local will be a cheaper or faster option ¯\_(ツ)_/¯
2019-09-25T13:14:34 < jadew`> karlp, in here Vodafone found a loophole and made it so it's not available on all plans
2019-09-25T13:14:53 < jadew`> it was available for about a year or so, but they changed that
2019-09-25T13:14:54 < Cracki> it's getting bad when you can't find anyone to PCBA locally at a reasonable price AND something prevents you from using chinese services
2019-09-25T13:15:31 < jadew`> Cracki, it's not just that, it's the mere competition coming out of china
2019-09-25T13:15:31 < Cracki> screwing consumers over? you need a government agency to combat that
2019-09-25T13:16:09 < jadew`> which, leaving production costs aside, it's unregulated
2019-09-25T13:16:20 < Cracki> hm right, romania and china compete on comparable technological levels, but vastly different cost of work
2019-09-25T13:16:39 < karlp> jadew`: so tell them you'll report them to efta, and then do so.
2019-09-25T13:16:42 < jadew`> that means you have to produce while following some very strict rules, while they don't
2019-09-25T13:16:55 < Cracki> that too :S
2019-09-25T13:16:57 < jadew`> you have to offer warranty and customer support, they don't
2019-09-25T13:16:59 < karlp> sorry, esa, not efta.
2019-09-25T13:17:16 < jadew`> karlp, I should report China?
2019-09-25T13:17:26 < karlp> I was talking about vodafone and the eu roaming
2019-09-25T13:17:35 < jadew`> ah
2019-09-25T13:17:39 < Cracki> maybe those rules need to change so you aren't as screwed as you are
2019-09-25T13:18:01 < jadew`> I'm sure others did it, the thing is that if the romanian law has that loophole, they'll abuse it until it's gone
2019-09-25T13:18:08 < jadew`> and it might take years until it's gone
2019-09-25T13:19:39 < karlp> you could exercise the four freedoms and move somewhere less romanian? :)
2019-09-25T13:20:13 < jadew`> karlp, yeah, but that's the situation everywhere in Europe
2019-09-25T13:20:30 < jadew`> was actually considering the US, but I don't know... it's too far
2019-09-25T13:20:53 < karlp> I'm still just talking about mobile roaming and local implementations of regs
2019-09-25T13:20:57 < zyp> hmm, Xiaomi A3 still doesn't have NFC
2019-09-25T13:21:21 < karlp> a2 had less features than a1 too iirc, 
2019-09-25T13:21:30 < jadew`> karlp, ah
2019-09-25T13:21:35 < karlp> I wouldn't buy a new one without nfc now.  it was a nice to have when I got mine.
2019-09-25T13:21:39 < zyp> and since last time I looked at a xiaomi phone, NFC has went from a thing that I use now and then to a thing I use pretty often
2019-09-25T13:21:47 < karlp> yar,  indeed :)
2019-09-25T13:22:08  * karlp shoudl go back to this power sequencing glitching spi clock on boot instead of offtopic chatz....
2019-09-25T13:22:16 < zyp> my bank got android pay support a few months back, I'm using that everywhere that has touch payment enabled now
2019-09-25T13:22:54 < zyp> for some reason not all places in norway has it enabled yet, even when the terminals support it
2019-09-25T13:23:16 < zyp> but when I went to poland in july I didn't even get my wallet out of the pocket even once
2019-09-25T13:23:38 < jadew`> jeez... they just sent me another form to fill :/
2019-09-25T13:23:54 < BrainDamage> here cash culture is pretty strong, but nearly everywhere you'll get a POS with CC and NFC
2019-09-25T13:24:13 < jadew`> one of the questions on that form is "What does the final user do?"
2019-09-25T13:24:38 < jadew`> how the hell should I know that? he's just a guy who bought something from me... ffs
2019-09-25T13:24:49 < BrainDamage> what's the product?
2019-09-25T13:24:55 < BrainDamage> is it test instrumentation?
2019-09-25T13:25:07 < BrainDamage> is it some sort of module?
2019-09-25T13:25:08 < jadew`> BrainDamage, yes
2019-09-25T13:25:19 < BrainDamage> then just say it's lab equipment
2019-09-25T13:25:24 < jadew`> it's a module, a prescaler for frequency counters
2019-09-25T13:25:35 < zyp> BrainDamage, I haven't used/carried cash much at all since I switched to my current bank 12 years ago, getting rid of transaction fees
2019-09-25T13:25:37 < jadew`> good idea
2019-09-25T13:25:46 < BrainDamage> then say it's a product meant to be integrated into a larger system
2019-09-25T13:25:48 < BrainDamage> if it's a module
2019-09-25T13:25:55 < zyp> when it doesn't cost anything to pay by card, there's no reason not to do that for everything
2019-09-25T13:26:39 < BrainDamage> I still prefer cash for menial things because it let me have a pretty solid feedback on the amount I'm spending
2019-09-25T13:27:07 < BrainDamage> supermarket and stuff goes through digital np
2019-09-25T13:27:29 < zyp> only time I don't use cash is when I go to jp, because they are weird about accepting foreign cards

2019-09-25T13:46:02 < jadew`> they have different categories based on sampling rate
2019-09-25T13:46:11 < jadew`> what a fucking waste of money
2019-09-25T14:01:04 < jadew`> here's another example of how stupid this whole thing is: there are no bookmarks

2019-09-25T14:07:06 < mitrax> hi
2019-09-25T14:08:06 < mitrax> i'm having a weird problem, openocd fails to flash with an "error waiting for target flash write algorithm" error. Oddly enough it works with the st-link utility, i'm having two boards in a batch that behave that way, the others work fine with openocd
2019-09-25T14:09:11 < zyp> is reset hanging?
2019-09-25T14:09:37 < mitrax> that's not the only problem on those two boards, the mcu apparently crashes on start (stuck in hard fault handler) as soon as the program uses the external xtal oscillator... but assuming there's something wrong with the quartz, that can't be related to SWD programming can it?
2019-09-25T14:10:55 < mitrax> zyp: no, after a reset it seems to be running once flashed with st-link, but crashed, i'm not 100% certain though 
2019-09-25T14:12:00 < sync> huh, I wonder how android pay works

2019-09-25T14:24:40 < zyp> mitrax, that doesn't look running to me
2019-09-25T14:25:08 < mitrax> zyp: I definitely have an oscillator problem on those board since if i keep running on the internal oscillator instead of switching to HSE the program runs (when flashed with st-link), but that shouldn't affect SWD programming should it? 
2019-09-25T14:25:37 < zyp> it's in lockup, which means it couldn't even trap the hardfault
2019-09-25T14:25:48 < zyp> which is what would happen if the flash is empty
2019-09-25T14:25:57 < zyp> so I'm not convinced it's actually flashed
2019-09-25T14:26:33 < mitrax> zyp: it is, if i read the flash with st-link and it matches the binary

2019-09-25T14:40:03 < karlp> yeah, I used to always laugh at the expiry dates on my cards when I lived in teh us.
2019-09-25T14:40:08 < zyp> I think I got a photo somewhere
2019-09-25T14:40:10 < karlp> no fucking chance they would ever last that long
2019-09-25T14:41:53 < englishman> usually it's shady bars and corner stores that have old terminals. and home Depot for some reason
2019-09-25T14:42:33 < englishman> the magstripe isn't actually used, all terminals have chip, but it's hard to use chip and pin with a phone
2019-09-25T14:42:38 < englishman> so magstripe is useful again

2019-09-25T20:30:17 < karlp> antto: tell me about it.
2019-09-25T20:30:25 < karlp> just got finished with an online chat with them,
2019-09-25T20:30:42 < karlp> found out that the differences between two I'm interested in is nylon 46 vs 66,
2019-09-25T20:30:51 < karlp> they don't mention that in their datasheets or product literature anywhere.
2019-09-25T20:31:52 < antto> well, today i went thru a few SAMTEC connector datasheets, while they were all stylized the same way, i found the much hard to figure out a part number for the combination i need
2019-09-25T20:32:48 < antto> aaaaand when i did, figured there is akchually no stock at all for any combo
2019-09-25T20:32:49 < antto> duh
2019-09-25T20:33:37 < karlp> samtec only has stock at samtec, don't even try finding it at digikey
2019-09-25T20:33:43 < karlp> samtec is a real cahnnel favourite too :)
2019-09-25T20:34:03 < karlp> a lot of it is made on demand.
2019-09-25T20:34:06 < antto> yeah i wondered why it sounded familiar
2019-09-25T20:34:21 < karlp> englishman ran into issues with them claiming stock, then having to manufacturer it when he actually ordered
2019-09-25T20:34:27 < karlp> they do crazy shipping things too
2019-09-25T20:34:48 < karlp> like ship a handful of tiny connectors in a meter long triangular tube, 15cm on a side and shit
2019-09-25T20:35:02 < antto> nah, i need something immediately available, this is one of those projects that has already been sold to the client.. before it even eggzists
2019-09-25T20:35:05 < karlp> bright side, you actaully _can_order direct from them, unlike amphenol et al
2019-09-25T20:35:37 < antto> amphenol looks huge and spilled over the globe
2019-09-25T20:35:57 < antto> they appear to have bough a bunch of manufacturers or something
2019-09-25T20:36:24 < antto> at least their part names make more sense than wurth electronics'
2019-09-25T20:39:11 < karlp> not sure I'd agree.
2019-09-25T20:39:19 < karlp> both use long strings of numbers with no clear ordering guides
2019-09-25T20:40:15 < antto> hm, maybe i've only seen a very tiny fraction of amphenol connectors

2019-09-25T20:42:28 < Steffanx> so i was looking for some corner clamps (not sure if that is a proper english name, but whatever). Found this: https://static.gamma.nl/dam/39428/41 
2019-09-25T20:42:32 < Steffanx> why that looks 3d printed.
2019-09-25T20:46:39 < kakimir32> welding clamp 90degrees
2019-09-25T20:46:57 < kakimir32> welders angle clamp
2019-09-25T20:48:09 < Steffanx> but it's just for wood.
2019-09-25T20:48:20 < Steffanx> very lightweight wood

2019-09-25T20:49:46 < Steffanx> i dont want those anyway, reviews are fucking terrible.

2019-09-25T22:00:09 < sync> zyp: basically they wanted to shove old shit cars out of the cities and introduced the plaque, but then the police said they are too busy to enforce it during running traffic
2019-09-25T22:00:55 < Steffanx> sync, soon you will no longer enter dutchland btw. We'll drive too slow for you. They have real plans to make the high ways 100km/h.
2019-09-25T22:00:56 < zyp> Steffanx, sure, if you want, doors are sold separately so you can select the style you want
2019-09-25T22:01:02 < zyp> naturally for shelves I won't bother with doors
2019-09-25T22:01:06 < sync> and the police is not responsible for offences on parked cars, so only the public orer office deals with it
2019-09-25T22:01:14 < sync> and they will not deal with foreign cars

2019-09-25T22:02:06 < zyp> well, it was just 5€ anyway
2019-09-25T22:02:06 < srk> ideally also cities to like 30km/h 
2019-09-25T22:02:11 < Steffanx> fuck no
2019-09-25T22:02:22 < zyp> Steffanx, also wat, why?
2019-09-25T22:02:35 < specing> yes, cities should be limited to 30km/h
2019-09-25T22:02:40 < Steffanx> NOx issues.
2019-09-25T22:02:41 < specing> ideally to 25km/h
2019-09-25T22:02:57 < zyp> we're going the other way here, politicians are pushing for higher speed limits
2019-09-25T22:03:04 < specing> ideally all cars would be banned
2019-09-25T22:03:26 < zyp> max used to be 100 km/h, got increased to 110 some years ago and they're pushing for even higher on new roads
2019-09-25T22:03:50 < Steffanx> Yes, but you dont have the emission "issue", zyp
2019-09-25T22:03:57 < Steffanx> because of the many EVs
2019-09-25T22:05:37 < zyp> speaking of, how's EV sales going in .nl?
2019-09-25T22:05:50 < Steffanx> idk. not well i think.
2019-09-25T22:06:09 < zyp> last I checked you guys were #2 after norway (in europe)
2019-09-25T22:06:13 < Steffanx> dutchies are not really into buying new cars.
2019-09-25T22:06:23 < Steffanx> and the 2nd hand EV market is smallish
2019-09-25T22:06:31 < zyp> that's a problem here too
2019-09-25T22:06:43 < Steffanx> our EVs are mainly hybrids i think.
2019-09-25T22:07:04 < Steffanx> i dont see em much in this region. Sometimes a tesla, perhaps a leaf.
2019-09-25T22:07:19 < Steffanx> But it might even the the same cars i see all the time.
2019-09-25T22:07:46 < zyp> it's just that EVs are so cheap to use here that paying more for a new EV rather than a used ICE car will pay itself off fairly quickly
2019-09-25T22:07:50 < sync> zyp: I can see why
2019-09-25T22:07:56 < Steffanx> i would buy a EV, but ... getting a loan for a car, nah thanks.
2019-09-25T22:08:37 < sync> I ripped up finland and down norway a few years ago on my motorcycle and I almost fell asleep sometimes because the streets were so empty, straight and slow
2019-09-25T22:08:47 < Steffanx> hah
2019-09-25T22:09:10 < zyp> my rule of thumb is that an EV costs about a fifth in electricity per km of what a gasoline car costs in gasoline
2019-09-25T22:09:30 < zyp> sync, where did you find straight roads in norway?
2019-09-25T22:10:04 < sync> that was more of an issue in .fi
2019-09-25T22:10:16 < Steffanx> How much is a liter of gasoline and what about diesel?
2019-09-25T22:10:36 < Steffanx> and electricity is probably pretty cheap there
2019-09-25T22:10:38 < zyp> I'm not keeping track
2019-09-25T22:10:59 < zyp> last I checked gasoline was in the range of 15-17 NOK/l or so
2019-09-25T22:11:06 < Steffanx> oh about the same as here.
2019-09-25T22:11:09 < zyp> diesel a bit cheaper
2019-09-25T22:11:35 < zyp> electricity is under 1 NOK/kWh most of the year
2019-09-25T22:11:48 < jpa-> sync: even in finland, there is usually a new straight road and a few decades older, curvy road to everywhere
2019-09-25T22:14:06 < sync> yeah, EVs are now more expensive to run than a diesel/gas engine here due to electricity costs
2019-09-25T22:14:21 < zyp> I think best case electricity for my car is around 0.1 NOK/km
2019-09-25T22:14:30 < zyp> i.e. around 1 EUR per 100km
2019-09-25T22:14:44 < Steffanx> in dutchland that would be around 2-2.5 then.
2019-09-25T22:14:46 < Steffanx> still not tooo bad
2019-09-25T22:14:59 < zyp> yearly average is probably significantly higher though
2019-09-25T22:15:17 < sync> yeah jpa-, sometimes it wasn't an option to take a detour tho
2019-09-25T22:15:21 < Steffanx> Still sad a pack of 8 stroopwaffles is cheaper than a L of diesel or gasoline.
2019-09-25T22:15:23 < zyp> both electricity prices and consumption is higher in winter
2019-09-25T22:15:36 < sync> just fill up in germoney Steffanx
2019-09-25T22:15:37 < zyp> oh, stroopwaffles
2019-09-25T22:15:45 < zyp> I need to order a load of those some time
2019-09-25T22:17:15 < Steffanx> sync, what's diesel there? Google says 1.25e. Not really worth the < 5 euro.
2019-09-25T22:18:19 < sync> last week it was about 1.2
2019-09-25T22:18:31 < zyp> speaking of EVs in germany; fun fact: I spent a grand total of 6.25€ on charging in germany when I went there
2019-09-25T22:18:48 < Steffanx> just ping me zyp. I'll order my sister to get me a full box of waffles right from the distributor. :)
2019-09-25T22:19:42 < Cracki> zyp, is it that heavily subsidized or didn't you drive that much?
2019-09-25T22:20:02 < Cracki> normal electricity costs an arm and a leg here
2019-09-25T22:20:11 < zyp> a bunch of the fast chargers didn't even require payment, idk why
2019-09-25T22:20:34 < zyp> I paid 5€ at one and 1.25€ at another, the rest were all free
2019-09-25T22:20:50 < englishman> maybe they realized if they asked for electronic payment, noone would pay, and noone makes coin-operated chargers
2019-09-25T22:20:54 < zyp> and I didn't pay anything extra to charge outside the hotel the places that were available either
2019-09-25T22:21:25 < englishman> since like 3 people in germany own electric cars, it's actually cheaper to give the electricity away than deal with payment processing
2019-09-25T22:21:37 < zyp> something like that
2019-09-25T22:21:52 < zyp> I assume it's subsidized in some way or another to get more people to buy electric cars
2019-09-25T22:23:28 < sync> yes and no
2019-09-25T22:23:35 < zyp> for comparison; I paid 38.48€ for charging in .nl
2019-09-25T22:23:43 < sync> only building the charging points is subsidized

2019-09-25T22:46:34 < zyp> but fast charging also pays for the infrastructure, not just electricity, so it's not directly comparable
2019-09-25T22:47:14 < zyp> and the bulk of charging is home charging, throwing in some expensive fast charging now and then doesn't mean much in the big picture

2019-09-25T22:50:47 < specing> electricity here is ~0.15 eur/kWh with taxes
2019-09-25T22:51:43 < englishman> now that is expensive
2019-09-25T22:51:46 < specing> They are ultimately shooting themselves in the foot by turning off nuclear power plants and making the price skyrocket
2019-09-25T22:52:02 < englishman> the fast charging, not so much, charging at 50kW takes some hardware
2019-09-25T22:52:31 < specing> you want electricity to be cheap, so that people heat their homes with 0emissions AC instead of with fossil fuels

2019-09-26T00:59:42 < jadew`> I'll have to write an app note or make a video (you can still link videos on ebay) where I explain that they will have a lot of loss at those frequencies, based on the cables and connectors they'll use
2019-09-26T01:01:00 < jadew`> also the fact that the sensitivity specification is affected by the connector option they buy the prescaler with, doesn't seem to be particularly clear, even tho it's mentioned in the datasheet (with pretty pictures)
2019-09-26T01:06:55 < machinehum> huh
2019-09-26T01:07:09 < machinehum> Yeah 8Gz has lots of hz's
2019-09-26T01:09:43 < jadew`> I mean... I have this on the product page: "For a better understanding on how the choice of connector affects the sensitivity, make sure to read the "Connector selection" section from the datasheet. To take advantage of the rated sensitivity, across the entire frequency span, you will need either the SMA option or the Low Loss TNC option. The base BNC and TNC assemblies will decrease the sensitivity by a
2019-09-26T01:09:45 < jadew`> couple of dB at around 8 GHz.

2019-09-26T01:19:25 < jadew`> ah, right, so they didn't bother to optimize them

2019-09-26T02:38:36 < jadew`> on the other hand the big mac was kinda tasteless and I thought they messed it up

2019-09-26T13:46:15 < karlp> so, 10uF is cheaper in 0805, but 4.7uF is cheaper in 0603.  nice to know where the inflection point is I guess.
2019-09-26T13:49:48 < karlp> that's exactly what my point was.  "bigger" capacitance is either less reliable or more expensive in the smaller packages, but where...
2019-09-26T13:51:02 < BrainDamage> yes, cost of process vs cost of package
2019-09-26T13:51:19 < BrainDamage> the inflexion point is where one takes over the other

2019-09-26T14:13:06 < karlp> fuckin kicad proud of their text files allowing diffs.
2019-09-26T14:13:15 < karlp> updated kicad, changed a footprint, saved.
2019-09-26T14:13:39 < karlp> thousands of lines of diffs because the newer version has re-ordered shit within the file for "reasons"
2019-09-26T14:14:29 < karlp> of course, you need to be on dev version to have actually recent features.
2019-09-26T14:14:34 < karlp> no release contains push/shove.
2019-09-26T14:16:19 < karlp> did you even fucking read what I said?
2019-09-26T14:17:14 < karlp> so.... re-ordering files is somehonw for you how to be able diff things?
2019-09-26T14:17:26 < karlp> it's literally what I'm complaining about making it harder to diff things.
2019-09-26T14:18:12 < karlp> they've literally moved every fp_line block from before fp_text blocks, to after fp_text blocks.  within the same indent level.  
2019-09-26T14:18:26 < karlp> it's not alphabetical anymore, so it sure feels like just being splatted
2019-09-26T14:18:41 < karlp> and it's resulted in gratuitous diffs of thousands of lines from no change
2019-09-26T14:19:35 < karlp> honestly, as far as I can tell from the diffs, they went from alphabetical within section to reverse alphabetical within sections.
2019-09-26T14:22:26 < sync> I think there are releases that include PNS

2019-09-26T16:58:44 < jadew> nothing changed
2019-09-26T16:59:00 < jadew> and you can find them cheaper at farnell (of all places)

2019-09-26T17:22:31 < karlp> it's ended up being ~€30 pcb+stencil (shipping included), vat on 30€+30€ (we didn't believe that shipping could be zero, so we've used a table to assign it) plus oh,,,,, let's just sway another €60 in "handling" hahahaha suckers...
2019-09-26T17:23:03 < karlp> including a nice 20€ charge for actualyl delivering it.
2019-09-26T17:23:22 < karlp> jadew: ordered from mouser this morning, price was lower once I logged in :)
2019-09-26T17:23:49 < jadew> I'm already logged in :)
2019-09-26T17:24:03 < karlp> and then aisler included "trust me, I'm a maker stickers" because, who wouldn't want them thrown in!
2019-09-26T17:24:09  * karlp is winning today
2019-09-26T17:24:18 < karlp> at least the pcbs and stencil look good.
2019-09-26T17:24:25 < karlp> gotta focus on the upside....
2019-09-26T17:24:36 < jadew> nice

2019-09-26T17:49:22 < karlp> the fees are just "fuck you, and fuck you again, and oh yeah, fuck you once more"
2019-09-26T17:49:58 < karlp> there's a bit of law we found that says that shipping has to be included in the vat bassis, even if it wasn't paid, and should then be "calculated"

2019-09-26T17:59:14 < benishor> which was crap compared to jlcpcb
2019-09-26T17:59:47 < benishor> so I sent an email to Felix with pictures and I got back "thanks for the headsup and the pictures.

2019-09-26T18:31:06 < benishor> one that would arrive faster
2019-09-26T18:31:21 < benishor> I can't say it took less than shipping from china
2019-09-26T18:44:15 < karlp> yeah, shipping was fast_er_ but not by much, though it largely seems to be because they just don't work weekends :)
2019-09-26T18:44:20 < karlp> so business days really mean that.
2019-09-26T18:44:44 < karlp> pcb specs are much higher than china boards, though, I'll give them that.

2019-09-26T20:06:12 < jadew> how much more do you end up paying with aisler?
2019-09-26T20:06:54 < jadew> for example, jlcpcb costs me ~80-100 USD, with shipping and taxes for 4 designs of 10 boards each
2019-09-26T20:07:17 < jadew> unfortunately, jlcpcb quality fluctuates from one order to the next
2019-09-26T20:07:23 < jadew> so you don't really know what you're getting

2019-09-26T20:19:02 < antto> but for short production time it gets pricy
2019-09-26T20:19:20 < karlp> "here" ?
2019-09-26T20:19:35 < antto> and they are local, so i don't know how the shipping and time delays will turn out if you order from outside
2019-09-26T20:19:38 < antto> karlp .bg
2019-09-26T20:19:38 < karlp> "Within no time, every member of the Internet of Things will be powered by the limitless, decentralized neutrino energy grid that is taking shape all over the planet"
2019-09-26T20:20:06 < karlp> antto: I even ordered pcbs from olimex back in they day whent hey did that.
2019-09-26T20:20:27 < antto> micron20 is one of the places, we ordered once from them, PCBs were gud, they have gud reviews on their website
2019-09-26T20:21:17 < antto> hard-tech is the other place, we order from them the past bunch of times, quality is gud, the soldermask positioning was bett0r than allpcb's "advanced production mode"
2019-09-26T20:21:22 < antto> which surprises me
2019-09-26T20:22:02 < antto> when i learnt about olimex, they had already stopped doing PCBs for mortalz
2019-09-26T20:22:16 < antto> and i wasn't kicading back then either
2019-09-26T20:22:27 < karlp> micron20 prices are wayyyy out of line :)
2019-09-26T20:22:48 < karlp> before even finding out abotu shipping
2019-09-26T20:22:56 < antto> yeah but tbh i liked the boards they made, their green soldermask was a noice shade of green
2019-09-26T20:23:23 < antto> like not very saturated, slightly yellow-ish maybe
2019-09-26T20:23:28 < antto> very gud green
2019-09-26T20:23:38 < antto> i don't have OCD, honestly
2019-09-26T20:24:25 < karlp> hardtech similar.  I'm sure they're fine, but just no advantages over even aisler.
2019-09-26T20:25:03 < antto> yes, as i said, they are eggspensive, but.. we haven't had any fuckups
2019-09-26T20:25:13 < antto> oh sh*t, i didn't censor that
2019-09-26T20:25:21  * antto hides behind the curtains
2019-09-26T20:25:26 < karlp> well, I've only ever had shipping niggles with anyone else anyway, so it's not fuckups I'm cocnered about
2019-09-26T20:25:37 < karlp> I'm just wanking over, in the scheme of things, small amounts of money
2019-09-26T20:26:26 < antto> now we ordered from allpcb, coz price, and the boss said "okay, enough with hard-tech, these are cheaper"
2019-09-26T20:27:35 < antto> speaking of .bg .. if you ever see "sirius-pcb" - close the tab immediately
2019-09-26T20:27:48 < antto> no, close the whole browser and run away without looking!

2019-09-27T00:51:53 < jadew> for those of you who have pushed more products out than I have: if you have a product that works well, but you know there's room for improvement and you can make it really good, do you release it with the problems and work them out in future revisions, or do you get it to a state where you're completely happy with it and only then start selling it
2019-09-27T00:51:55 < jadew> ?
2019-09-27T00:54:16 < Steffanx> No, you make it V2 :P
2019-09-27T00:54:26 < jadew> the thing I'm talking about... I've been working on it for several years and I know there are some issues to tackle, I know I can correct them, but at the same time I also want to put it on the market and see how it does, before I sink any more time into it

2019-09-27T00:54:42 < jadew> Steffanx, yeah, that's what I was thinking, but I'm not sure it's the right call
2019-09-27T00:56:15 < jadew> I mean, I would document every flaw, but then people might be turned off by that or have those specs stuck into their head and avoid V2 because of that
2019-09-27T00:57:10 < jadew> if I decide to work the kinks out, I'm looking at another 3-4 months delay
2019-09-27T00:57:48 < jadew> there's custom machining involved, and because it's a RF board, there's little I can hack on the spot, for every test there's usually a new board
2019-09-27T00:58:57 < karlp> ship it. sell them a new and improved version later.
2019-09-27T00:59:07 < karlp> tryt not to end up sitting on too much v(n-1) inventory

2019-09-27T01:00:20 < jadew> that sounds like a decent plan
2019-09-27T01:01:01 < jadew> my nature compels me to get everything to work as perfect as possible, but I know that's counter productive at times

2019-09-27T02:06:02 < aandrew> jadew: I have my mixdown.ca/redmine for issue tracking (you don't see my internal projects) so I don't forget about them and if I want I can come back and address them later, using the issue tracker to jog my memory/prioritize

2019-09-27T02:31:56 < jadew> aandrew, yeah, I have lots of todo lists and issue documentation for everything
2019-09-27T02:32:36 < jadew> I agree, I don't have to obsess over it
2019-09-27T02:33:14 < jadew> it's already extremely good
2019-09-27T02:34:31 < jadew> oh well, time for bed, tomorrow I'll have to start looking for suppliers that can produce my front panel
2019-09-27T02:36:36 < aandrew> well... I've got a GPSDO, an AD9959 DDS eval board, an ADF4351 eval board, a little LNA, some attenuators and a bunch of semirigid SMA jumpers. enough stuff to half ass enough RF to be dangerous
2019-09-27T02:37:29 < aandrew> oh and there's an ERASynth Mini waiting for me to pick it up too, along with a LimeSDR mini
2019-09-27T02:37:30 < jadew> nice
2019-09-27T02:37:50 < aandrew> I need a decent VNA and I think I'm pretty much set for most 433-2.4GHz shits
2019-09-27T02:38:10 < jadew> the limesdr should be able to do some VNA stuff
2019-09-27T02:38:22 < jadew> btw, I have a product for that
2019-09-27T02:38:36 < aandrew> yeah, I've not been having much luck getting Lime to do anything useful, but i think it's because I'm trying to use it with OSX
2019-09-27T02:38:43 < aandrew> oh? what's that?
2019-09-27T02:38:47 < jadew> https://cojotech.com/media/datasheets/LMT-030-2%20-%20Datasheet.pdf
2019-09-27T02:39:09 < jadew> it's so you don't fry it during experiments
2019-09-27T02:39:15 < aandrew> a nice little limiter, yes
2019-09-27T02:39:18 < aandrew> that's your build?
2019-09-27T02:39:23 < jadew> yeah
2019-09-27T02:39:31 < aandrew> nice. what's inside it?
2019-09-27T02:39:48 < jadew> diodes
2019-09-27T02:39:54 < aandrew> interesting
2019-09-27T02:40:12 < jadew> extremely tricky to get those specs
2019-09-27T02:40:19 < aandrew> I do not doubt it
2019-09-27T02:40:29 < aandrew> where do I buy such a thing so that you get the money
2019-09-27T02:41:03 < jadew> if you decide you need one, I'll give you a big discount
2019-09-27T02:41:16 < jadew> dpm
2019-09-27T02:41:26 < aandrew> how much do they normally sell for? I have no idea
2019-09-27T02:41:52 < aandrew> oh wait it's righ ton that website

2019-09-27T05:55:29 < ColdKeyboard> I'm trying to figure out something; When I have laptop connected, and using ADC to get the value from the current transformer, I get ~0 when there is no current draw and about ~1500 when my water kettle is turned on. However when I disconnect the laptop, when everything is off, I'm reading ~1000 on the ADC...
2019-09-27T05:55:51 < ColdKeyboard> My laptop is battery powered so it's not connected to earth ground
2019-09-27T05:56:41 < ColdKeyboard> Curious what could be the cause of this since this is the only delta (connecting FT232 to the board and to my laptop through USB)
2019-09-27T06:01:43 < Cracki> wat
2019-09-27T06:03:14 < ColdKeyboard> I have his board that has differential amplifier for current sensor (https://www.amazon.com/ZIYUN-Transformer-Principle-Electricity-Consumption/dp/B01FBMFZCO) and output of that amplifier is fed to the STM32F072's ADC
2019-09-27T06:03:19 < ColdKeyboard> *this
2019-09-27T06:04:21 < ColdKeyboard> Weird thing is that when board is connected to my laptop via USB2UART converter, it's working as expected. But when I disconnect the USB2UART converter, the values seem to go completely out of whack
2019-09-27T06:08:41 < Cracki> grounding issues
2019-09-27T06:08:49 < Cracki> or what
2019-09-27T06:09:43 < Cracki> so what, it does 0~30A AC -> 0-1V?
2019-09-27T06:10:07 < Cracki> you must have hooked it up shoddily?

2019-09-27T06:19:07 < Cracki> "out of whack" sounds very much like bad wiring
2019-09-27T06:23:57 < ColdKeyboard> Seems like grounding issue but I'm not sure how connecting a laptop, that is battery powered removes that issue?
2019-09-27T06:32:53 < Cracki> I'd say it's the usb connection that helps
2019-09-27T06:32:59 < Cracki> or maybe power is shit
2019-09-27T06:33:02 < Cracki> probe it
2019-09-27T06:33:17 < Cracki> how do you even power that thing if it's not attached to the laptop

2019-09-27T07:14:36 < Cracki> so the adapter might be to blame
2019-09-27T07:15:11 < Cracki> you need to mention such things first, i.e. when you remove something (laptop), what you replace it with (phone charger)

2019-09-27T22:13:05 < kakimir32> so I have ntfs file system MFT mirror found in the image
2019-09-27T22:13:12 < kakimir32> there is no primary anything left
2019-09-27T22:13:16 < kakimir32> also no mbr left
2019-09-27T22:15:00 < kakimir32> how do I reconstruct it?
2019-09-27T22:15:19 < kakimir32> it needs to be done manually with these "templates"
2019-09-27T22:15:37 < kakimir32> you input values into fields and location where you want the thing
2019-09-27T22:16:40 < kakimir32> it applies the tempate to the image per your parameters set
2019-09-27T22:23:47 < qyx> englishman: I am using this http://www.ti.com/lit/gpn/bq28z610 and I am not able to bootstrap it
2019-09-27T22:23:55 < qyx> or better, idk how should it behave
2019-09-27T22:24:35 < qyx> if I short the mosfets, battery voltage appears on the pack output, the chip boots and tries to keep the mosfets on
2019-09-27T22:24:44 < qyx> but somehow the gate voltage collapses
2019-09-27T22:25:43 < qyx> I am suspecting the 10M resistors
2019-09-27T22:26:53 < qyx> I mean, I used 1M, it may be the cause

2019-09-27T22:53:15 < Cracki> I looked at a freshly created ntfs partition and checked what patterns I saw
2019-09-27T22:53:24 < kakimir32> oh
2019-09-27T22:53:33 < kakimir32> this one is from win xp or so
2019-09-27T22:53:52 < Cracki> I think the first and last sector are identical, and I had a template for this that let me enter values
2019-09-27T22:54:09 < Cracki> you could send it to rossmann repair group :>

2019-09-28T06:12:59  * jadew is learning how to deal with a device that's running at a high temperature
2019-09-28T06:13:14 < jadew> interesting things happen
2019-09-28T06:14:09 < jadew> in this case some characteristics change permanently over the first couple of hours of operation
2019-09-28T06:33:23 < ColdKeyboard> I asked this last night but the router crashed and I got disconnected and went to sleep after...
2019-09-28T06:33:24 < ColdKeyboard> I have this circuit that is being powered by 5VDC coming from USB charger -> https://i.imgur.com/O5Nthgc.png
2019-09-28T06:33:35 < ColdKeyboard> When I have my laptop connected and reading the UART output, ADC value is around 1500 when load is turned on and about 50-100 when it's off.
2019-09-28T06:33:45 < ColdKeyboard> However, when I disconnect my laptop, the ADC goes out of whack and reports 1200 ADC when there is no load
2019-09-28T06:33:56 < ColdKeyboard> My laptop is being battery powered when connected to the board so there should be no earth ground reference.
2019-09-28T06:34:05 < ColdKeyboard> Anyone experienced something like this before or knows what could fix this?
2019-09-28T06:34:50 < ColdKeyboard> I'm getting the ADC values from STM32F070's built in ADC but I don't think anything's wrong with the ADC
2019-09-28T06:42:06 < machinehum> CT1 is where your analog signal is coming in?
2019-09-28T06:44:09 < ColdKeyboard> Yes, it's one of those current transformers

2019-09-28T06:53:08 < machinehum> Also don't people normally drop a CT over a resisor and sample the voltage

2019-09-28T06:53:19 < machinehum> In a differential fasion?
2019-09-28T06:54:22 < ColdKeyboard> I'm trying to wrap my head around the fact that board that is powered by the phone charger, works fine when USB2UART is connected to _battery powered_ laptop, and then goes out of whack when you remove the USB2UART but still use same charger, same sensor, same circuit... everything is left the same
2019-09-28T06:54:51 < ColdKeyboard> And yes, you would usually want to drop the voltage over a resistor and have a ESD diode to protect the CT and your circuit
2019-09-28T06:55:29 < machinehum> what is this USB2UART you speak of?
2019-09-28T06:55:54 < machinehum> How are you reading the ADC?
2019-09-28T06:56:12 < machinehum> Through gdb?

2019-09-28T07:02:09 < ColdKeyboard> It's FTD232 breakout board that I connect GND and RX to my board and then other end goes to my laptops USB port
2019-09-28T07:02:32 < ColdKeyboard> I'm printing ADC values over UART and also logging them over BLE
2019-09-28T07:05:00 < machinehum> So how do you know your ADC values get fucked up
2019-09-28T07:05:11 < machinehum> if you disconnected the ftdi
2019-09-28T07:08:14 < ColdKeyboard> I read the value ove BLE

It isn't enough that the Romans erected great building when Germans lived in primitive mud huts, no, we must dig up these mud huts and proudly prove that we were throwing stone axes when Greece and Rome had the highest level of culture. We really should do our best to keep quite about this, present day Romans must be laughing at us.

2019-09-29T06:27:11 < nuxil> I got my timer6 triggering @ N freq. How can i calculate the execution time of my code within the interrupt handler? can i use DWT and the Cycle Count Register?
2019-09-29T06:27:36 < nuxil> something like this http://paste.debian.net/1103230/ ?
2019-09-29T06:29:30 < nuxil> and if so. assume the code takes 200 cycles.  do i use my trigger freq or timer freq to cal the total time ?

2019-09-29T06:31:31 < dongs> ur quite a madlad there
2019-09-29T06:31:48 < nuxil> i know
2019-09-29T06:32:59 < nuxil> just wanted to see result. ofc i dont use that in my code.
2019-09-29T06:33:07 < dongs> debugging is a thing you know
2019-09-29T06:33:53 < dongs> when I want to know timing of things and its more than oen thing i usually just make a struct debug{} or something with a bunch of ints in there, make it global and watch in watch window during runtime
2019-09-29T06:33:54 < nuxil> debugging is nice until you see a B instrucs. 
2019-09-29T06:34:12 < nuxil> is it like 2 cycles. 3 cycles 4 cycles :p
2019-09-29T06:34:18 < R2COM> use visual watch in VisualGDB
2019-09-29T06:34:41 < R2COM> not sure about how down in cycle difference you can go tho
2019-09-29T06:34:52 < jadew> roomba, thanks, I'll check it out
2019-09-29T06:34:54 < nuxil> B is 2 or 3 or 4. depends.
2019-09-29T06:35:16 < nuxil> it can be either of them. depends on next instrucs etc.
2019-09-29T06:43:36 < dongs> nuxil: teh fuck are you on? if you want cycle count between entry/.exit to interrupt, do what you do, then stick teh difference into a global var/struct and watch that sthi in debugger

2019-09-29T07:27:08 < jadew> what do you guys think it's a better idea for a front panel? paint or sticker?
2019-09-29T07:27:37 < jadew> some of the older pieces of test gear seem to use paint, but I'm not sure if it's liquid paint or powder
2019-09-29T07:28:36 < jadew> new ones have either printed plastic or sticker
2019-09-29T07:29:35 < jadew> the problem with the sticker is that I have to apply it myself and I'm not sure if I can align it well
2019-09-29T07:35:39 < dongs> judew, why not just use chinapcb for front panel
2019-09-29T07:35:51 < dongs> mask + silkscreen
2019-09-29T07:35:52 < dongs> done
2019-09-29T07:36:13 < jadew> dongs, not pro enough
2019-09-29T07:36:17 < dongs> how so
2019-09-29T07:36:29 < jadew> I need countersunk holes
2019-09-29T07:37:07 < jadew> but yeah, that would be nice
2019-09-29T07:37:17 < dongs> https://www.takachi-el.co.jp/products/EXPE no you just need enclosures like this
2019-09-29T07:37:46 < dongs> i'm using the orange one wiht front panel w/pcb and its amaze
2019-09-29T07:38:21 < jadew> that looks good, but it's too late now, I already chose an enclosure and everything is designed around it
2019-09-29T07:38:38 < jadew> how much is that enclosure in qty?
2019-09-29T07:38:40 < dongs> anyway sticker works. or pay your enclosure place to silkscreen it
2019-09-29T07:39:05 < dongs> lke 25bucks or something , cheap enough for me
2019-09-29T07:39:06 < jadew> yeah, those are the choices, sticker or the enclosure mfg to paint and silkscreen
2019-09-29T07:39:11 < jadew> yeah, that's good
2019-09-29T07:39:30 < dongs> i've done silkscreen with them it looks amazing but like 20 cases qty becoems something like 600bux with silkscreen

2019-09-29T07:52:43 < dongs> wait is that 3d dicked
2019-09-29T07:52:55 < dongs> hm i'd say for that kinda setup youre gonna have to payup for stencil
2019-09-29T07:52:55 < jadew> only the bumper
2019-09-29T07:53:05 < dongs> stickers on that would look gay as fuck
2019-09-29T07:53:23 < dongs> unless you can get some reverse -transfer stickers where you have the bottom adhesive and then peel off top clear stuff and the letters remain
2019-09-29T07:53:23 < jadew> yeah, I got a quote for the entire box + painted panels + stencil
2019-09-29T07:53:59 < jadew> with sticker I was thinking an entire sticker (with the white bg included)
2019-09-29T07:54:10 < jadew> what you see there is actually a sticker, but I don't like it
2019-09-29T07:54:18 < jadew> it's not sticky enough and not thick enough
2019-09-29T07:54:28 < jadew> I want one with matte plastic over it
2019-09-29T07:54:38 < dongs> oh, you mean entire front panel is a sticker?
2019-09-29T07:54:41 < jadew> (to make it scratch resistant)
2019-09-29T07:54:42 < dongs> like the tek control panel
2019-09-29T07:54:43 < jadew> yeah
2019-09-29T07:54:47 < dongs> which is matte
2019-09-29T07:54:47 < jadew> exactly
2019-09-29T07:54:48 < dongs> ya that would work
2019-09-29T07:55:51 < jadew> think it would be better than paint?
2019-09-29T07:56:02 < dongs> yeah if that kinda matte vinyl sticker yes
2019-09-29T07:56:04 < jadew> my concern with paint is that it might scratch away
2019-09-29T07:56:31 < jadew> while with the stickers I'm afraid I won't line it up nicely and it will look like shit
2019-09-29T07:57:29 < jadew> and of course, to try either it costs ~600 EUR
2019-09-29T07:58:06 < jadew> because that's the MOQ for the boxes, with or without the paint/silkscreen
2019-09-29T07:58:42 < dongs> why wouldnt it line up nicely
2019-09-29T07:58:46 < dongs> are stickers from same place?
2019-09-29T07:58:50 < jadew> no
2019-09-29T07:59:11 < jadew> actually, I didn't ask if they do stickers
2019-09-29T07:59:34 < jadew> but I assume I'll have to make the holes like... 0.2 mm wider and crap like that
2019-09-29T07:59:40 < jadew> to account for alignment errors
2019-09-29T08:17:24 < dongs> but they're all covered by a hex nut or somethign anyway
2019-09-29T08:17:46 < dongs> acutally i think on tek, the front panel STICKER holes are on-size and underlying plastic is bigger
2019-09-29T08:18:04 < dongs> so you actualyl have to make your underlying material bigger hole and then precision-cut vinyl
2019-09-29T08:18:14 < jadew> dongs, yeah
2019-09-29T08:18:19 < jadew> just a bit bigger
2019-09-29T08:18:39 < jadew> but aligning it is a bitch
2019-09-29T08:18:57 < dongs> not really
2019-09-29T08:19:01 < dongs> its just a sticker man
2019-09-29T08:20:02 < jadew> I guess I'll give it a try and see how it goes
2019-09-29T08:20:35 < jadew> I'm sure I'll get at least a couple of them right

2019-09-29T09:53:58 < dongs> nah nothing just the price
2019-09-29T09:54:06 < jadew> because amphenol does some of the best connectors
2019-09-29T09:54:13 < dongs> 23c for amphenol vs 2c for china clones

2019-09-29T11:18:49 < dongs> oh the swithc? i donno its good, has wide grab even for SMT and 2 boss pins so its harder to tear off
2019-09-29T11:19:11 < dongs> ive been using a chinaname for it but finally tracked down the manufacturer/datasheet
2019-09-29T11:19:23 < dongs> also known as LY-A03-01
2019-09-29T11:29:17 < karlp> is that U254-051T-4BH23-S2B footprint compatible with the amphenol one?
2019-09-29T11:29:23 < dongs> almost
2019-09-29T11:29:31 < dongs> its like 0.1mm +- in places
2019-09-29T11:29:44 < dongs> i extended the footprint and amphenol 3d model still fits
2019-09-29T11:29:49 < dongs> so I think its prolly OK

2019-09-29T12:24:58 < jpa-> though apparently bluepill is not very well supported by micropython currently, i've used stm32f4 nucleo
2019-09-29T12:27:55 < dongs> why teh fuck would you use python for i2c on a fucking mcu
2019-09-29T12:28:01 < dongs> retarded fucking hipsters

2019-09-29T12:29:58 < Jak_o_Shadows> dongs, I just want to test some of the hardware out - the i2c slaves and what they do.
2019-09-29T12:30:28 < srk> we've considered writing something like slcan for spi/i2c so you can get standard device interface on linux and tunnel over uart to mcu
2019-09-29T12:30:35 < dongs> i guess im lucky i have USB bridges with i2c master on them that i've wrritten stuff for so I can use it from any code easily
2019-09-29T12:30:53 < dongs> so i dont have to do anything retarded like python

2019-09-29T14:27:17 < Jak_o_Shadows> Why do people use stuff like the bus pirate then?
2019-09-29T14:30:54 < jpa-> because the GUI's for various ftdi i2c devices tend to suck
2019-09-29T14:31:33 < Jak_o_Shadows> Fair enough
2019-09-29T14:31:59 < jpa-> secondary reason: if you need some fast roundtrip action like "read value, write value depending on it", with usb you usually get ~1ms latency
2019-09-29T14:32:25 < jpa-> whereas even slowish micropython running on stm32 can get down to ~1us
2019-09-29T14:43:23 < Jak_o_Shadows> yep.
2019-09-29T14:48:28 < jpa-> smbus devices are particularly annoying to debug with, as they have pretty short timeouts for everything

2019-09-29T16:41:08 < catphish> morning
2019-09-29T16:41:20 < Steffanx> Gooday mr catphish
2019-09-29T16:41:32 < dongs> fuck off with dmy and shit.
2019-09-29T16:41:36 < dongs> Y/M/D is the one true way
2019-09-29T16:41:47 < dongs> 2001/09/11
2019-09-29T16:41:52 < Steffanx> ok
2019-09-29T16:43:25 < roomba> what about mdy?
2019-09-29T16:43:47 < Steffanx> even worse.
2019-09-29T16:43:58 < dongs> mdy is OK cuz murica but ymd is best
2019-09-29T16:44:25 < roomba> seconds from unix epoch is even better than best
2019-09-29T16:44:36 < Steffanx> Yes because everyone can remember that.
2019-09-29T16:44:41 < dongs> literally nobody gives a fuck about lunix epoch
2019-09-29T16:44:57 < dongs> around lunix time 2427389746276 they said lunix was gonna be on desktop
2019-09-29T16:44:59 < dongs> LOL
2019-09-29T16:45:15 < roomba> lunix makes a great desktop
2019-09-29T16:45:27 < dongs> desktop->doorstop
2019-09-29T16:45:30 < Steffanx> Wouldnt 2427389746276 overflow on the average lunix computer?
2019-09-29T16:45:30 < dongs> if so, agreed
2019-09-29T16:46:54 < roomba> you're biased against the lunix presumably because your life path made more sense on windows
2019-09-29T16:47:09 < roomba> there is nothing wrong with lunixes.
2019-09-29T16:47:16 < roomba> they have their place
2019-09-29T16:47:39 < Steffanx> one thing windows still cant do right though? This spot lightish thingy when you hover over a date when you click on the clock is still broken
2019-09-29T16:48:03 < Steffanx> It's better since last update, but still broken.

2019-09-29T16:49:38 < Steffanx> it's the only relevant windows atm.
2019-09-29T16:49:47 < rajkosto> wrong
2019-09-29T16:49:54 < roomba> they care more about roomba'ing up user data than making a good OS. i anticipate a mass exodus soon to the lunix.
2019-09-29T16:50:11 < specing> Oh wow, people still use windows in 2019?
2019-09-29T16:50:19 < specing> Someone tell them its 2019 already
2019-09-29T16:50:28 < roomba> all the ST stuff runs on lunix.
2019-09-29T16:51:02 < Steffanx> but lunix isnt written in Ada. Fuck off with lunix.
2019-09-29T16:51:15 < roomba> even works on archlinux. it used to be rare to see proprietary stuff like stm32cubemx run on anything but ubuntu.
2019-09-29T16:51:36 < specing> Steffanx: at least its FOSS
2019-09-29T16:51:43 < specing> thats like ... halfway there :P
2019-09-29T16:52:14 < specing> Steffanx: iirc, US DoD actually mandated the Ada compiler to be GPL
2019-09-29T16:52:34 < roomba> i learned recently that there is a fork of vscode that removes as much telemetry as possible. that's actually a thing.
2019-09-29T16:52:45 < Thorn> that's why gnat costs 5 figures for commercial use?
2019-09-29T16:54:07 < specing> Thorn: someone has to fund its development
2019-09-29T16:54:52 < specing> and you can use it commercially without an AdaCore license, you just have to have your own runtime library, iirc

2019-09-29T18:11:12 < dongs> not identifying as a supplier
2019-09-29T18:11:17 < tcth> alright
2019-09-29T18:11:18 < tcth> anyone else?
2019-09-29T18:11:26 < dongs> i'd imagine any of the current stuff from cypress/whoever works just fine
2019-09-29T18:11:38 < dongs> hell, if you dont care about HAL, you can prolly just use a stm32g0
2019-09-29T18:11:50 < tcth> I assume making a 100W charger is not going to me much more complext than making a 20W one, right?
2019-09-29T18:11:59 < dongs> yes, its just negotiation part
2019-09-29T18:12:11 < dongs> for the voltage/current

2019-09-29T18:23:36 < tcth> yeah, I was just starting to look into that
2019-09-29T18:23:40 < dongs> you'd need 24V psu and another richtek dcdc to step down 5/9/12/20V
2019-09-29T18:23:56 < tcth> seems difficult to come by
2019-09-29T18:23:56 < Steffanx> digikey seems to have it.

2019-09-29T18:24:56 < tcth> dongs, where did you get the ´and another dcdc step down´ from?
2019-09-29T18:25:09 < tcth> ah, their shit is proprietary to their other shit
2019-09-29T18:25:12 < dongs> the 'DC-DC converter' block in top right
2019-09-29T18:25:16 < dongs> nah its not
2019-09-29T18:25:31 < dongs> i mean dude, they're just adjusting VFB voltage
2019-09-29T18:25:40 < dongs> you could nigger it up with any existing dc/dc but why not just use shit that works
2019-09-29T18:25:59 < tcth> I assume the stuff at the bottom (provider schematic) I´ll simply omit? The USB MUX / PD MUX and Audio stuff
2019-09-29T18:26:23 < dongs> yes all those are useless
2019-09-29T18:26:40 < tcth> I wonder if I even need any MCU on this

2019-09-29T18:31:49 < tcth> like flyback and stuff
2019-09-29T18:32:06 < Laurenceb_> because it can do voltage conversion?
2019-09-29T18:32:42 < Steffanx> why dont you just clone a chink psu?

2019-09-29T18:33:35 < dongs> its same as the ti or richtek part
2019-09-29T18:35:40 < dongs> haha STUSB thing just sets up multiple dividers on GPIO bits and then adds them up
2019-09-29T18:35:43 < dongs> to change FB voltage
2019-09-29T18:35:54 < dongs> yeah actualyl STUSB is super easy to use

2019-09-29T18:37:25 < dongs> thats same as richtek thing, with a 24V PSU which gets stepped down to required voltage by using shitty generic dc/dc converter

2019-09-29T20:51:10 < Laurenceb_> in theory
2019-09-29T20:51:18 < Laurenceb_> maybe it will be fixed by usb4
2019-09-29T20:51:59 < Steffanx> sure, but .. what Laurenceb_ said englishman
2019-09-29T20:52:29 < englishman> uh what does usb4 have to do with pd

2019-09-29T21:03:19 < Steffanx> and not the standard notebook/laptop crap
2019-09-29T21:03:31 < englishman> of course
2019-09-29T21:04:02 < Steffanx> i dont
2019-09-29T21:04:15 < Laurenceb_> my thinkpad has it, only it doesnt work
2019-09-29T21:04:32 < roomba> you better be running arch on that thinkpad

2019-09-29T21:05:07 < Steffanx> my laptop thingy has it too, but i yet have to find a compatible charger. Never really looked into one myself, only read about people having issues.

2019-09-29T21:06:21 < qyx> speaking of power delivery, is there any offgrid prepper
2019-09-29T21:07:02 < Laurenceb_> >offgrid prepper USB class?
2019-09-29T21:07:03 < qyx> isn't there lack of electricity in englishland
2019-09-29T21:07:43 < Laurenceb_> preppers are weird and stupid
2019-09-29T21:07:43 < Laurenceb_> like if there was a nuclear war I'd just hangout in local disused rail tunnels after raiding supermarket
2019-09-29T21:08:04 < roomba> offgridUSB
2019-09-29T21:08:10 < Laurenceb_> preppers would build a godzillion dollar bunker that would be a magnet for criminals
2019-09-29T21:08:20 < roomba> i keep my shit off grid
2019-09-29T21:08:53 < Cracki> >rail tunnel
2019-09-29T21:08:57 < Cracki> >magnet for criminals
2019-09-29T21:09:23 < qyx> if there is a nuclear war, your life is fukd
2019-09-29T21:09:48 < Cracki> mutually assured destruction. not gonna happen

2019-09-29T21:10:00 < qyx> so idk if a bunker of a rail tunnel is a solution
2019-09-29T21:10:07 < Laurenceb_> someone should trigger that PERSON Stallman by calling him StallMAN 
2019-09-29T21:10:07 < Laurenceb_> wrong
2019-09-29T21:10:11 < Cracki> I do wonder... some nations with nukes, if they dropped one on europe, would immediately get protection from murica
2019-09-29T21:10:47 < qyx> roomba: are you making 230V out of it
2019-09-29T21:10:56 < roomba> qyx: 120V yes
2019-09-29T21:11:10 < roomba> i have a small inverter that can be used to power and charge laptop
2019-09-29T21:11:21 < englishman> what do you mean you cant find a compatible charger Steffanx
2019-09-29T21:11:29 < roomba> previously i was using a 12V power supply but it caused battery expansion in a laptop
2019-09-29T21:11:31 < englishman> did it not come with a charger
2019-09-29T21:12:08 < roomba> so even though using an inverter is less efficient, it's safer on laptops battery than using some chink power brick
2019-09-29T21:13:47 < qyx> I am trying to shop for inverters in EU and it seems that 3kW+ offgrid is unobtainable
2019-09-29T21:14:08 < qyx> maybe except victron
2019-09-29T21:14:55 < roomba> be weary of the 1kw+ ones

2019-09-29T21:15:34 < roomba> the majority of them - even the so-called quality ones will explode if you try to use them with large power tools or appliances
2019-09-29T21:16:14 < qyx> I have a 1kVA one and it is good even with circular saw and stuff
2019-09-29T21:16:29 < qyx> sofar
2019-09-29T21:16:35 < roomba> yeah circular saws and grinders and stuff are ok
2019-09-29T21:17:12 < roomba> i'm talking like stationary bandsaws and stuff
2019-09-29T21:17:53 < roomba> thuogh imo if you're requiring 1kw and beyond for anything other than refridgeration, you're doing it wrong.
2019-09-29T21:18:12 < roomba> get a generator for the big shit
2019-09-29T21:18:26 < roomba> it's cheaper and less risky of exploding your inverter
2019-09-29T21:18:57 < qyx> fridge is ~100w only with some spike during strtup
2019-09-29T21:19:32 < qyx> also, my inverter is properly fused
2019-09-29T21:20:00 < qyx> but Ill search youtube for "exploding inverter"

2019-09-29T21:20:24 < englishman> literally first google search result
2019-09-29T21:21:10 < qyx> mhm
2019-09-29T21:23:21 < englishman> victron looks nice and not too expensive either

2019-09-29T23:30:37 < qyx> karlp: I need to investigate with a scope, I have two usb->rs485 converters and two modbus slaves handy, invertek optidrive and that chinesium mppt
2019-09-29T23:31:08 < qyx> the invertek works with the first converter (ftdi + rs485 transceiver)
2019-09-29T23:31:46 < qyx> the mppt charger not.. (with the same rs485 converter), only 0x00 or 0x01 bytes are received
2019-09-29T23:32:26 < qyx> and the other way around, with the other rs485 converter, neither of the devices work
2019-09-29T23:32:52 < qyx> also, I was not able to communicate with the two converters connected together
2019-09-29T23:33:35 < qyx> so I am suspecting the mppt charger and the other rs485 converter to be both broken, although not in the same way

2019-09-30T00:47:02 < bitmask> did you sand it or did it come off the cnc that smooth?

2019-09-30T04:08:33 < jadew> spoke to an electrician at a wedding today
2019-09-30T04:09:08 < jadew> he works at the electric power company and he said that when working on the 20 kV lines they can't approach it too fast
2019-09-30T04:09:22 < jadew> they have to go slow, otherwise they risk getting electrocuted
2019-09-30T04:10:10 < jadew> I didn't understand the processes tho
2019-09-30T04:10:16 < jadew> (didn't ask either)
2019-09-30T04:10:51 < Cracki> >electric altar
2019-09-30T04:10:57 < jadew> lol
2019-09-30T04:11:06 < Cracki> sounds like superstition
2019-09-30T04:11:30 < Cracki> has anyone ever been struck by lightning for not approaching deferentially?
2019-09-30T04:11:46 < jadew> well, apparently the lather they use to climb there has a built in slowness when it approaches that height
2019-09-30T04:12:08 < Cracki> besides, they shouldn't approach live 20 kV anyway. that's what those big switches are for.
2019-09-30T04:12:22 < jadew> I assume sometimes they have to do it

2019-09-30T04:13:10 < jadew> he mentioned a distance of 1.5 m

2019-09-30T04:13:30 < Laurenceb_> lmao wtf
2019-09-30T04:13:33 < jadew> said that within that range, if you approach it too fast or move away too fast, you can get electrocuted

2019-09-30T04:16:14 < jadew> when I was in school we were taught not to make too big steps around fallen wires
2019-09-30T04:16:32 < jadew> I guess it could be a similar thing
2019-09-30T04:16:36 < jadew> Cracki, yeah
2019-09-30T04:16:41 < jadew> 50 Hz @ 20 kV
2019-09-30T04:16:44 < Cracki> *that* i understand. resistance of ground is higher than your own, so current might go through your legs if they're too far apart
2019-09-30T04:16:54 < jadew> or rather 20 kV @ 50 Hz
2019-09-30T04:17:16 < jadew> Cracki, yeah, but at 20 kV we might be talking about electric field gradients
2019-09-30T04:17:18 < Cracki> so no argument for static charge in any way
2019-09-30T04:17:28 < Cracki> yes, electric field gradient
2019-09-30T04:17:39 < jadew> although, they do change constantly... at 50 Hz
2019-09-30T04:17:45 < jadew> so I'm not sure if that's it either
2019-09-30T04:17:55 < Cracki> right
2019-09-30T04:18:03 < Cracki> but what's 50 hz anyway
2019-09-30T04:18:20 < jadew> 20 ms
2019-09-30T04:18:26 < jadew> it's fast
2019-09-30T04:18:27 < Cracki> eons
2019-09-30T04:19:09 < jadew> yeah, I don't know if that's faster or not than a fast movement :)
2019-09-30T04:20:39 < jadew> he said that it doesn't matter what you're wearing (protective gear or not), it will "get" you
2019-09-30T04:21:11 < Laurenceb_> interesting

2019-09-30T04:21:18 < jadew> which is why none of them is wearing protective gear
2019-09-30T04:21:28 < jadew> (I'm kidding)
2019-09-30T04:39:54 < Cracki> sounds ever more like superstition
2019-09-30T04:40:49 < jadew> if it's field related (and it would have to be) then there's not much protective gear that could be of any use
2019-09-30T04:40:55 < Cracki> can't get people to move with intent near dangerous things unless you scare them
2019-09-30T04:41:29 < Cracki> if it's field related, distance should be a factor, but not speed
2019-09-30T04:41:34 < jadew> you think it's a tactic to keep them safe?

2019-09-30T04:42:10 < jadew> next time I'll meet him, I'll ask more
2019-09-30T04:42:12 < jadew> he's a relative
2019-09-30T04:42:36 < Cracki> maybe it's taught in trade school, they should know why it is
2019-09-30T04:43:30 < jadew> maybe it's how fast the arc can extend once it starts going?
2019-09-30T04:43:42 < jadew> *how far
2019-09-30T04:44:31 < jadew> so if you by mistake get close enough to start it, you'd have to get back to ~1.5 m away to stop it?
2019-09-30T04:44:36 < Cracki> that's beyond human time scales
2019-09-30T04:44:43 < Cracki> ah that?
2019-09-30T04:44:46 < Cracki> not sure
2019-09-30T04:45:17 < Cracki> either way, if you have a thread of plasma on your skin that MAINTAINS itself, you're unlikely to still have good motor control
2019-09-30T04:45:50 < Cracki> if it's high frequency, skin will tingle, but 50 hz isn't nearly high enough

2019-09-30T04:48:56 < Cracki> the density and proximity of antennas is because it propagates so shit, not because they need more power

2019-09-30T04:53:09 < Cracki> I need to look up his credentials. he must have won them in a lottery.
2019-09-30T04:53:35 < jadew> his explanation is that EMF activates some channels in the cells
2019-09-30T04:53:53 < jadew> his exact words: "some channels"
2019-09-30T04:54:04 < Cracki> at what dose
2019-09-30T04:54:10 < Cracki> he doesn't say
2019-09-30T04:54:20 < Cracki> sure, a microwave oven activates all kinds of shit
2019-09-30T04:54:30 < jadew> I'd like to know what channels those are
2019-09-30T04:54:32 < Cracki> sure, if you eat a pound of salt you're dead
2019-09-30T04:54:57 < jadew> actually, from what I hear a microwave oven will just heat you up

2019-09-30T04:57:35 < jadew> there's no mention of power tho
2019-09-30T04:57:42 < Cracki> of course not
2019-09-30T04:57:44 < jadew> how strong does that field has to be?
2019-09-30T04:58:08 < jadew> if they tested it on a rat that was sitting inside an MRI... then sure
2019-09-30T04:58:27 < jadew> but incident waves hitting your skin... they're going to stop there
2019-09-30T04:58:51 < Cracki> no quantitative statements so far
2019-09-30T04:59:36 < jadew> sort of like free energy, where they're measuring either voltage or current, but not both

2019-09-30T05:02:54 < Cracki> for some truth one would have to hunt down the references and check them
2019-09-30T05:04:48 < jadew> if what that guy had was true, he would have presented the figures himself
2019-09-30T05:05:29 < Cracki> it certainly seems that electric and magnetic fields have some effect on immune system and whatnot
2019-09-30T05:05:48 < Cracki> I opened the first reference. they play with magnetic fields on the order of milliteslas
2019-09-30T05:06:23 < Cracki> don't see frequencies so far
2019-09-30T05:06:36 < Cracki> it's like "OMFG bananas are radioactive, don't touch them"
2019-09-30T05:09:40 < Cracki> here's something with 1 mW/cm2 and MHz ranges https://pdfs.semanticscholar.org/eccb/73f1d0ff3d417621d81e1a0589b6556e0838.pdf
2019-09-30T05:10:05 < Cracki> if all of that is true, it applies to all the radio we already have
2019-09-30T05:11:00 < jadew> I'll have to read it tomorrow when I'm fully awake
2019-09-30T05:11:02 < jadew> what does it say?
2019-09-30T05:11:34 < Cracki> lymphocytes affected. I think their action was depressed. don't have the concentration to be sure.
2019-09-30T05:11:42 < jadew> EMF nurtures cellular growth?
2019-09-30T05:11:54 < jadew> I see
2019-09-30T05:11:56 < Cracki> they do talk about effects strongest for certain frequency bands
2019-09-30T05:13:29 < Cracki> so if he says he wants more studies, sure I'm all for that.
2019-09-30T05:14:29 < jadew> yeah, that paper seems interesting
2019-09-30T05:14:36 < jadew> I think I'll move to the country side
2019-09-30T05:14:59 < jadew> and have my lab in the next room

2019-09-30T05:18:24 < jadew> even told my wife - not sure how much she enjoyed that :P
2019-09-30T05:18:25 < roomba> who watching with?
2019-09-30T05:18:31 < roomba> oh
2019-09-30T05:18:36 < roomba> ok don't watch midsommar with wifey
2019-09-30T05:19:05 < jadew> another drama/trhiller?
2019-09-30T05:19:06 < roomba> or don't watch it yourself. unless you wanna get mindfucked
2019-09-30T05:19:09 < jadew> why not?
2019-09-30T05:19:16 < jadew> really?
2019-09-30T05:19:18 < jadew> now I'
2019-09-30T05:19:22 < jadew> now I'm curious

2019-09-30T05:22:00 < roomba> other ones i just watched that were kinda ok: arctic, captive state
2019-09-30T05:22:44 < Cracki> this pall guy is the only one who publishes on this topic. I haven't seen coauthors in his papers yet.
2019-09-30T05:22:53 < jadew> I'll check them out, thanks
2019-09-30T05:23:08 < roomba> Cracki: i think that's because research like this is probably not well funded?
2019-09-30T05:23:23 < Cracki> every reference he uses just sticks to biochemistry. he's the one linking that to neurological effects.
2019-09-30T05:23:35 < Cracki> research like that probably IS well funded
2019-09-30T05:23:43 < Cracki> NIH and such fund that stuff I'm sure
2019-09-30T05:24:24 < Cracki> this is a study on mice, but AGAIN just using low frequency radio https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0197054
2019-09-30T05:25:04 < Cracki> I want a study that progressively nukes mice and I want to see the range from placebo to LD50

2019-09-30T12:50:27 < zyp> I got one of the poe things that I used to pad a farnell order once, but I don't got a poe-capable rpi yet

2019-09-30T12:59:01 < Ecco> Hi :)
2019-09-30T12:59:14 < Ecco> I'm trying to guesstimate the power usage of an eink panel
2019-09-30T12:59:28 < Ecco> I quite don't know where to start, I couldn't find a good datasheet
2019-09-30T12:59:41 < zyp> start by defining a usage pattern
2019-09-30T12:59:55 < zyp> the point of eink is that they don't consume any power when they are in a steady state
2019-09-30T13:00:12 < Ecco> yep
2019-09-30T13:00:21 < Ecco> this I understood
2019-09-30T13:00:29 < Ecco> but I was wondering how much current would be drawn and for how long
2019-09-30T13:00:39 < Ecco> to update, let's say, a 10x10 pixel area
2019-09-30T13:00:59 < zyp> IIRC you need a boost converter to drive them, so I figure efficiency of that would factor into the equation
2019-09-30T13:01:10 < Ecco> ok
2019-09-30T13:01:18 < zyp> and startup/shutdown times, again depending on your usage pattern
2019-09-30T13:01:30 < Ecco> indeed
2019-09-30T13:01:35 < Ecco> https://www.eink.com/product.html?type=productdetail&id=17
2019-09-30T13:01:49 < Ecco> this for example seems to have everything needed in the module
2019-09-30T13:01:55 < Ecco> but there's no datasheet :(
2019-09-30T13:02:21 < zyp> well, there is, they just don't give it to you
2019-09-30T13:02:49 < Ecco> yeah :)
2019-09-30T13:02:57 < Ecco> This one they even sell a dev kit of
2019-09-30T13:02:59 < Ecco> https://shopkits.eink.com/product/2-9%cb%9d-epaper-display-el029tr1/
2019-09-30T13:04:38 < jpa-> Ecco: it will also depend hugely on the display size
2019-09-30T13:04:52 < Ecco> Ok, makes sense
2019-09-30T13:05:10 < Ecco> But I'm having a hard time getting some actual numbers
2019-09-30T13:05:12 < jpa-> on 800x600 panel, it takes ~100mA during the update, which is from 100 ms to a second depending on if you need grayscale and how clean
2019-09-30T13:05:20 < Ecco> ok
2019-09-30T13:05:22 < jpa-> (100mA @ 3.3V)
2019-09-30T13:05:58 < Ecco> I assume the power consumption is proportional to the size of the updated area
2019-09-30T13:06:02 < Ecco> is that correct?
2019-09-30T13:06:05 < jpa-> you can also update slower which will kind of take less power, except you will need to run the boost converter longer so any losses will add up
2019-09-30T13:06:33 < jpa-> the time taken for update is proportional to the updated area height (number of scanlines)
2019-09-30T13:06:38 < jpa-> width doesn't matter
2019-09-30T13:06:43 < Ecco> oh, ok, that's fun
2019-09-30T13:07:25 < jpa-> but the power consumption during that time is higher the more transistors there are total on the scanline, so for bigger displays it both takes longer to update and the current during it is higher, so O(n^2) or perhaps even O(n^3)
2019-09-30T13:07:35 < Ecco> oh, ok
2019-09-30T13:09:46 < jpa-> boost converter efficiency will vary a lot based on your supply voltage; for 3.3 -> ~20V boost, the efficiency is below 50%; but if your system had e.g. 12V battery, it could be ~80% efficient
2019-09-30T13:10:21 < zyp> is the boost stuff voltage or current regulated? could you just run a 20V battery? :p

2019-09-30T13:12:00 < jpa-> zyp: voltage regulated
2019-09-30T13:12:13 < zyp> is it very picky on voltage?
2019-09-30T13:12:42 < jpa-> if you want to use predefined waveforms for accurate grayscale, it is kind of
2019-09-30T13:12:54 < jpa-> but otherwise not really
2019-09-30T13:13:13 < jpa-> the one i used wanted +22V, -20V, +15V and -15V

2019-09-30T22:22:08 < catphish> this is starting to get annoying now, i've changed my name, but banks seem intent on only opening accounts matching what's on my passport
2019-09-30T22:22:13 < catphish> i guess it's time to get a new passport
2019-09-30T22:23:08 < qyx> why are they even interested in your passport?
2019-09-30T22:23:21 < qyx> I have never had any passport in my life
2019-09-30T22:23:26 < catphish> dunno, just standard policy i guess to make sure your name is right
2019-09-30T22:23:31 < catphish> they'd also accept a driving licence
2019-09-30T22:23:41 < qyx> don't you have an ID card?
2019-09-30T22:23:49 < catphish> no such thing in my country
2019-09-30T22:23:53 < qyx> O-o
2019-09-30T22:23:56 < qyx> weird
2019-09-30T22:24:38 < catphish> in the UK, there's no central database of people per-se
2019-09-30T22:25:59 < catphish> there's birth records, tax records, driving licence records, passport applications, but no official documentation of "identity", you just exist
2019-09-30T22:27:12 < catphish> but because of modern crime i geuss, banks have started requiring a driving licence or passport to have some traceability of who you are
2019-09-30T22:29:02 < Steffanx> Why on earth would you change your name, catphish
2019-09-30T22:29:11 < catphish> as a consequence, there's no official record of what your name is, you can use whatever name you like, but for many practical purposes you have to buy a new driving licence before you can use it
2019-09-30T22:29:22 < catphish> (or passport)
2019-09-30T22:29:32 < Steffanx> You already had such fancy name
2019-09-30T22:30:02 < catphish> it's not that i changed my name, its more that the name my parents wrote on my birth certificate is one i've never chosen to use
2019-09-30T22:30:10 < Steffanx> aha
2019-09-30T22:30:16 < catphish> but it still sticks to me
2019-09-30T22:30:49 < catphish> one day i'll get round to officially asking for a new passport and driving licence in the right name
2019-09-30T22:32:06 < catphish> it's a trivial change anyway "Charles Allen Anson" -> "Charlie"
2019-09-30T22:32:23 < PaulFertser> How about sex/gender marker, is it harder to change?
2019-09-30T22:32:48 < Steffanx> i always asociate the name Charlie with a cat. Blame jly/stvn/crt/whatevernickheuses for that.
2019-09-30T22:32:48 < catphish> that's a complicated question
2019-09-30T22:33:16 < catphish> PaulFertser: in 99.9% of cases, people are going to determine your gender just by looking
2019-09-30T22:33:46 < catphish> PaulFertser: afaik the only case where it would matter if if you had to go to prison, i've heard a lot of people have problems with that
2019-09-30T22:34:45 < catphish> again, this is something that's just copy/pasted from birth certificate to passport, then copied by anyone who insists on looking at your passport
2019-09-30T22:35:27 < catphish> anyway, it seems that i have to go through the dull process of applying for a new passport and writing a letter confirming my new name
2019-09-30T22:35:46 < PaulFertser> catphish: how about getting an official job, I guess the HR looks at the passport or driving license and if the marker doesn't match your appearence it might get problematic? 
2019-09-30T22:36:11 < catphish> PaulFertser: i can't think why an employer would need to know your gender or care
2019-09-30T22:37:38 < catphish> it's illegal to hire based on gender anyway, so i can't think why they'd need proof of it
2019-09-30T22:38:29 < PaulFertser> catphish: many people care about plenty of bullshit, just to have something to chat about. 
2019-09-30T22:39:03 < catphish> employers here are supposed to see some proof of your nationality (to make sure you have EU nationality so you have the right to work here)
2019-09-30T22:39:24 < catphish> but other than that, they don't ask for much
2019-09-30T22:39:25 < PaulFertser> It might change in a month ;)
2019-09-30T22:39:48 < zyp> employers here need your SSN for tax reporting and stuff, and SSNs here are gendered
2019-09-30T22:40:14 < zyp> IIRC one of the digits is odd or even depending on gender
2019-09-30T22:40:48 < catphish> interesting, don't think we have that here, we do have a tax id number, but it doesn't mean anything, just an identifier
2019-09-30T22:41:01 < zyp> not sure if people who gets a legal sex change gets a new SSN though
2019-09-30T22:41:14 < PaulFertser> That's interesting!
2019-09-30T22:41:37 < catphish> we have an SSN (we call it NI number), and it's used as a tax ID, but that's all its used for
2019-09-30T22:41:50 < zyp> ah, indeed, you do get a new SSN if you get a legal sex change
2019-09-30T22:42:07 < catphish> and i don't think it really matters if you don't have one, you just pay tax at normal rate until you get issued one
2019-09-30T22:42:41 < zyp> we call it «personnummer», i.e. person-number
2019-09-30T22:42:56 < zyp> everybody gets one, it's a national ID
2019-09-30T22:43:02 < catphish> i know nothing about legal sex change, but i know most people like to get a new passport (like you would for a new name), dunno if you need proof, you probably do
2019-09-30T22:45:03 < Steffanx> At least your name is like.. genderless. At least it's in this country.
2019-09-30T22:45:10 < zyp> there's like three number series used here, the normal one that starts with your six-digit birthdate, another range that starts with an offset for temporary immigrants, and a third range that hospitals and similar use for patients they don't know the real ID of
2019-09-30T22:45:18 < catphish> well it is, but i'm pretty confident i'm a man
2019-09-30T22:45:51 < zyp> daughter had a bracelet with the latter kind after she was born, before she was assigned the normal one
2019-09-30T22:46:06 < catphish> there's very little need to "prove" your ID or gender here, opening a bank account is the only important one, or maybe a criminal record check for some jobs
2019-09-30T22:46:31 < zyp> so this stuff is used for anything here, medical, bank, tax, drivers license, etc…
2019-09-30T22:46:39 < catphish> other than that, people pretty much just believe you
2019-09-30T22:46:47 < catphish> medical of course doesn't matter here

2019-09-30T22:47:16 < catphish> but yeah, bank, passport, driving licence are the main ones, with he latter two being the only official forms of ID we have
2019-09-30T22:47:21 < zyp> also there's a national people registry that couples your id to your name, so when you get a name change you only need to register it there
2019-09-30T22:47:32 < catphish> that's the part we dont have
2019-09-30T22:47:44 < catphish> you don't have an "official" name

2019-09-30T22:49:34 < qyx> we have something similar like zyp
2019-09-30T22:49:40 < zyp> yeah, countries do stuff differently
2019-09-30T22:50:04 < qyx> 6 numbers from the birthdate, 4 numbers looks random
2019-09-30T22:50:04 < catphish> but of course your're right, if you call yourself "lady bigtits delicious" at a job interview and then they notice your passport (that you show to prove you're an EU national) says "charlie smurthwaite", they're going to think you're a weirdo
2019-09-30T22:50:54 < PaulFertser> I guess those numbers might have some "checksum" embedded.
2019-09-30T22:51:01 < catphish> afaik nobody would do anything with your SSN other than copy/paste it onto tax forms
2019-09-30T22:51:14 < zyp> my wife took my surname after we got married, but she's foreign and didn't bother updating the registry in her home country
2019-09-30T22:51:18 < catphish> don't think UK ones have any cool hidden meanings
2019-09-30T22:51:28 < zyp> so she technically have two different official names, depending on which country you ask
2019-09-30T22:52:12 < qyx> is he japanese
2019-09-30T22:52:15 < zyp> which means that daughter is also getting a dual citizenship, and probably different surnames on each
2019-09-30T22:52:15 < qyx> she I mean
2019-09-30T22:52:34 < catphish> yeah, this is the hassle
2019-09-30T22:52:42 < zyp> qyx, yes
2019-09-30T22:52:57 < qyx> wat, I was not serious
2019-09-30T22:53:01 < catphish> and frankly, i'm just lazy, all i have to do is write to the passport office to tell them my new name (my wife managed it when she married me)
2019-09-30T22:53:03 < zyp> I am :)
2019-09-30T22:53:09 < qyx> :)
2019-09-30T22:53:10 < Steffanx> lol
2019-09-30T22:53:46 < zyp> catphish, we have online forms for that stuff
2019-09-30T22:54:01 < zyp> pretty much all official paperwork is done online here
2019-09-30T22:54:19 < catphish> an online form would be lovely, maybe they have that now
2019-09-30T22:55:00 < qyx> we did a bunch of stuff online this year for the first time
2019-09-30T22:55:24 < qyx> now when we finally have working eIDs
2019-09-30T22:56:01 < zyp> registering daughter's name was also done online, I just logged in and filled out a form, and then wife got an email that she also had to log in and approve it
2019-09-30T22:56:06 < catphish> https://i.imgur.com/MZjhY56.png - that's what the UK passport office wants
2019-09-30T22:56:30 < catphish> ah interesting also - https://www.gov.uk/changing-passport-information/gender
2019-09-30T22:56:33 < zyp> haha, that sounds so backwards
2019-09-30T22:56:43 < catphish> we have a "Gender Recognition Certificate"
2019-09-30T22:56:44 < zyp> that you have to use a new name to change to it
2019-09-30T22:56:57 < catphish> zyp: like i said, there's no "official" name in the UK
2019-09-30T22:57:00 < zyp> here you would register a name change first, then start using the new name
2019-09-30T22:57:13 < catphish> so you use whatever you like, then the official documentation reflects it
2019-09-30T22:57:27 < zyp> as I said, backwards :)
2019-09-30T22:57:30 < qyx> here iit is the other way around
2019-09-30T22:57:45 < qyx> you have to make the change first to oficially use it
2019-09-30T22:57:49 < catphish> presumably historically everywhere worked like the UK
2019-09-30T22:57:58 < qyx> noone is going to give you a driving license for a non recognized name
2019-09-30T22:58:06 < catphish> there must have been a time in history where no country had a central database
2019-09-30T22:58:13 < zyp> oh, we also have official addresses along with the names
2019-09-30T22:58:20 < qyx> we too
2019-09-30T22:58:26 < zyp> some stuff only send you mail to the official addr
2019-09-30T22:58:44 < catphish> but over time i guess people made databases, then eventually started making laws saying you're only supposed to use the name in the database
2019-09-30T22:59:22 < qyx> because otherwise people would do I am groot
2019-09-30T23:00:21 < catphish> of course the crux of the issue is "who cares" and i mean that literally
2019-09-30T23:00:42 < catphish> i mean, some people will have access to a central database, others will want proof, others will take your word for i
2019-09-30T23:00:44 < catphish> *it
2019-09-30T23:01:18 < catphish> the UK just happens to have 3+ different databases, none of which are compulsory
2019-09-30T23:01:40 < zyp> sounds like a hassle to maintain
2019-09-30T23:01:43 < catphish> driving licence, tax, passport (i guess the tax one is compulsory if you earn money)
2019-09-30T23:02:04 < catphish> and yes, in my case i have to update all of them separately, i already told the tax people because they have a simple free online form
2019-09-30T23:02:30 < catphish> now i'm waiting to have a stack of paperwork from the tax people to show the passport people
2019-09-30T23:02:51 < catphish> once that's done, the driving licence people will accept the new passport and update their database accordingly
2019-09-30T23:04:39 < catphish> i'm sure these systems aren't so different, it's just that we have no one single official database of names, nor any laws about what name you can use
2019-09-30T23:05:12 < catphish> i think maye you're not allowed to use honorary titles if you didn't earn them :)

2019-09-30T23:08:44 < catphish> i looked at using the ST provided USB library with its mass storage support, but i was a bit confused about how it works, when the PC tries to read a block, it calls a function that expects you to respond with that block of data, that makes sense on the surface, but i don't want to be doing all my work to find the data in that callback :(

2019-09-30T23:21:02 < machinehum> I guess that would need to be integrated into the RTOS?
2019-09-30T23:21:36 < machinehum> Because async would need to fuck with the PC

2019-09-30T23:42:40 < zyp> coroutines are a form of cooperative multitasking and might eliminate the need for any form of preemptive multithreading
2019-09-30T23:42:50 < specing> zyp: or you could use Ada. It has had threading for the past few decades
2019-09-30T23:42:56 < zyp> so you might not really need much more of a rtos around it
2019-09-30T23:43:34 < machinehum> But you can do coop multitasking in a normal rtos anyways...
2019-09-30T23:43:47 < machinehum> Any everyone just uses priorities

2019-09-30T23:44:13 < zyp> specing, I prefer languages invented after people figured out too much verbosity is annoying
2019-09-30T23:44:49 < specing> zyp: Ada is not that verbose
2019-09-30T23:44:58 < zyp> machinehum, yeah, just saying you can often drop all that once you've got coroutines
2019-09-30T23:45:00 < specing> However, Ada was designed to be readable
2019-09-30T23:45:03 < specing> unlike C++...
2019-09-30T23:46:00 < zyp> languages that uses shit like begin/end for delimiting blocks are too verbose.
2019-09-30T23:47:22 < machinehum> Yeah it would be cool if it was just build into the language
2019-09-30T23:47:40 < machinehum> I wonder if there's going to be a giant function stack or something
2019-09-30T23:47:41 < specing> I could say the same about languages that use {} for delimiting blocks
2019-09-30T23:47:52 < specing> you should use Python
2019-09-30T23:47:53 < machinehum> I think that's how js does it
