hey azonenberg, random observation: i think your Coolrunner-II dev board has too much capacitance
<rqou>
iirc usb limits the effective capacitance to 10uF
<azonenberg>
oh the vbus rail?
<azonenberg>
yes, i have zero inrush limiting
<lain>
it's ok
<lain>
nothing obeys that
<azonenberg>
you cant make any kind of reasonable smps with 10uf input cap
<lain>
iirc the spec is specifically that you can't present >10uF capacitance without inrush limiting... or more specifically, the purpose, iirc, is to prevent inductive kick from unplugging cables
<lain>
if you suddenly unplug a long usb cable with >10uF on the other end, there's a pretty huge inductive kick that can damage things
<rqou>
"nothing obeys that" <-- just like the suspend current limit?
<rqou>
also, bad excuse because the xc2 board doesn't even have an smps :P
<balrog>
lain: has anyone retested it?
<balrog>
that's kinda old, might be from factory firmware (which had numerous bugs)
<lain>
balrog: I'm curious about that as well
<lain>
in particular my Switch hasn't exploded when used with other USB-C compliant chargers, etc
<azonenberg>
rqou: what about the "dont pull more than 100 mA until you negotiate high power"?
<azonenberg>
you know how much obeys THAT?
<azonenberg>
:p
<rqou>
lol

random question: is there any kind of standard for what pins an "arduino-like" is supposed to have?
<rqou>
or does everyone just yolo it?
<pie_>
i honestly havent figured out what arduino even means
<pie_>
not that i tried too hard
<pie_>
my best conjecture to this point is something you can program via the arduino ide :P
<jn__>
my guess: "standards?? just copy the pinout!"
<awygle>
it's always weird to me when programs working hard consume Exactly Two hyperthreads
<awygle>
like, if you're parallel, grab ALL the cores! that's what they're there for! and if you're not parallel... how are you using the second core/hyperthread?
<pie_>
xD
<awygle>
maybe this is how "maximum turbo mode on one core" is being reported or something
<lain>
awygle: on my old desktop I had to pin a game to a single physical core (two logical cores because hyperthreading) to get smooth gameplay, because although the game took advantage of all my cores, it wasn't parallel enough and it only ran smoothly when using a single core to get turbo boost
<lain>
using more than one core, it quickly hit thermal limits and couldn't turbo anymore
<awygle>
lain: i suppose that's not unreasonable. sounds like badly implemented parallelism though.
<lain>
yeah
<lain>
that game's code was uh.. magical, I'm sure. given the network sync issues.
<lain>
I still miss it though :( it got shutdown in december, before even getting out of beta. I archived all versions of it that were ever published on Steam and started cracking the DRM (which requires talking to their server before the game will even /start/), but I haven't had time to poke it lately
<pie_>
what game was it
<lain>
I'd like to preserve it but it's gonna be a long road lol
