@mntmn out of interest, what was up with the HDMI on 4k60 and what was the fix?

Graham Sutherland / Polynomial (gsuberland@chaos.social)'s status on Tuesday, 16-Apr-2024 13:10:57 JST Graham Sutherland / Polynomial so as for *why* the PuTTY P-521 bug happened: they wrote the implementation in September 2001, which is a month before Windows XP was released. Win9x had no good random number generator APIs, so they came up with an alternative trick using SHA512 to generate deterministic but non-predictable nonces. but, of course, SHA512 outputs are 512 bits long, not 521 bits, and they just left the other 9 bits at zero, which resulted in this problem. the code was not reviewed since, so it never got fixed.

Graham Sutherland / Polynomial (gsuberland@chaos.social)'s status on Tuesday, 16-Apr-2024 13:10:56 JST Graham Sutherland / Polynomial without digging into the full details of how the determinism stuff interplays with the protocol stack, their solution actually might have worked out ok if they had generated a second hash to fill the last 9 bits.
if they had happened to write this implementation just a month or two later, they could've written it to use CryptGenRandom on XP or later, and fallen back to the deterministic approach on Win9x, and this bug would've been avoided.

(no idea on the specifics)

Graham Sutherland / Polynomial (gsuberland@chaos.social)'s status on Wednesday, 20-Mar-2024 04:05:20 JST Graham Sutherland / Polynomial @mntmn the alignment on that one to the north isn't great either, but that's a surprising level of error for a single misalignment.
if you check other boards, are they correct, or are they also offset and just happen not to be shorting?

Graham Sutherland / Polynomial (gsuberland@chaos.social)'s status on Thursday, 01-Feb-2024 05:07:28 JST Graham Sutherland / Polynomial @foone honestly the board is a really common culprit for this kind of random crash, and it sounds like you've already eliminated everything else. I know it's annoying to RMA but right now it's by far the most likely culprit.
-
Graham Sutherland / Polynomial (gsuberland@chaos.social)'s status on Thursday, 01-Feb-2024 04:19:01 JST Graham Sutherland / Polynomial @foone (honestly at this point I'd just RMA the board given that you've tried two lots of RAM and CPU failures are super rare)

Graham Sutherland / Polynomial (gsuberland@chaos.social)'s status on Thursday, 01-Feb-2024 04:15:01 JST Graham Sutherland / Polynomial @foone I really don't think it's thermals. Sounds like a bad motherboard or PSU. Does memtest return clean?

Graham Sutherland / Polynomial (gsuberland@chaos.social)'s status on Monday, 29-Jan-2024 07:41:56 JST Graham Sutherland / Polynomial there's a saying in electronics that there are two types of PCB designers: people who make antennas on purpose and people who make antennas by accident.
and having looked at a bunch of designs made by big companies recently, I think more PCB designers should go be antenna designers instead, because they've clearly got some innate skill at it which is currently untapped.

Graham Sutherland / Polynomial (gsuberland@chaos.social)'s status on Saturday, 20-Jan-2024 21:20:20 JST Graham Sutherland / Polynomial I swear I've seen at least a dozen people in the last month alone complain about multiple failed components and continuous hardware issues and build quality issues in framework laptops. for how much those things cost it's deeply disappointing to see.
-
Graham Sutherland / Polynomial (gsuberland@chaos.social)'s status on Saturday, 20-Jan-2024 21:20:19 JST Graham Sutherland / Polynomial imma be honest, seeing multiple people report failed motherboards within warranty and then the warranty replacement motherboard failing just outside warranty is not a great look
(especially when this is accompanied by complaints about other hardware issues happening at the same time, like trackpads and displays going bad)

Graham Sutherland / Polynomial (gsuberland@chaos.social)'s status on Saturday, 20-Jan-2024 21:20:17 JST Graham Sutherland / Polynomial with sincere apologies to the folks who work on this stuff who follow me - I know you do really good work - I've kinda lost a lot of confidence that this "open laptop" thing is gonna be sustainable enough to push through and grow into something more mainstream. I hope I'm wrong, but... *sigh* idk. it's just starting to seem like a lot of money for less performance and less reliability and ultimately there's still reliance on the original manufacturer for repairs most of the time anyway.

Graham Sutherland / Polynomial (gsuberland@chaos.social)'s status on Saturday, 20-Jan-2024 21:20:16 JST Graham Sutherland / Polynomial and this makes me very sad because it's such a cool concept that has the right spirit and vibe about it, but I've kinda lost faith that it can be squared with the reailities of producing good quality computing hardware with the kind of reliability and support that is warranted at a pricetag necessary to fund operation.

Graham Sutherland / Polynomial (gsuberland@chaos.social)'s status on Saturday, 20-Jan-2024 21:20:14 JST Graham Sutherland / Polynomial the super-fans who will pay a fortune to use half-broken hardware and mess with warranty replacements several times just because "open laptop" fits their general ethos can only really take you so far
-
Graham Sutherland / Polynomial (gsuberland@chaos.social)'s status on Saturday, 20-Jan-2024 21:20:13 JST Graham Sutherland / Polynomial I think the crux of it is that I'm sure it's possible for an organisation to exist which can build high performance open hardware laptops with excellent reliability at a moderate premium above similar spec'd closed products, with sufficiently capable production pipelines to keep on top of demand and warranty parts, but I'm no longer confident that it's possible to attain that state because you need to make so many things that don't compete first and navigate all that mess and technical debt.

Graham Sutherland / Polynomial (gsuberland@chaos.social)'s status on Saturday, 20-Jan-2024 21:20:12 JST Graham Sutherland / Polynomial organic growth means that such an endeavour takes so long that you end up burned out or swamped under technical (and possibly financial) debt.
artificial growth (like, say, some youtuber with tens of millions of subs says they're investing in your business) means the demand rockets beyond your capabilities and your supply chain is instantly backlogged for years and everything falls apart.
and at any point on this ride you can make one misstep or get tunnel vision and WOMP WOMP you're bust.
