<rqou> i love webpki disasters
<rqou> can someone convince me why moving to trust-on-first-use doesn't work?
<sorear> what happened this time?
<rqou> some reseller emailed a bunch of private keys (that they had saved?!) to the CA to force revocation
<whitequark> rqou: because certificates change
<whitequark> even barring that, large websites have a certificate per load balancer or data center
<rqou> yeah? HPKP has a mechanism to handle cert changes
<rqou> and can pin an intermediate
<whitequark> that's not TOFU
<rqou> why not?
<rqou> it can become TOFU if you just ignore whether the cert validates against the PKI and only check HPKP
<whitequark> let's say you TOFU for an intermediate
<whitequark> then your intermediate becomes compromised
<whitequark> what next
<rqou> shrug and do the normal rotation procedure?
<rqou> it's not like revocation really works now anyways
<rqou> offtopic: nonlinear systems are really cool
<rqou> er, they make really cool pictures
<rqou> the diffeq theory is maddening because i'm absolutely no good at it

<rqou> OMGWTF
<rqou> apparently jupyter notebook as a race condition between clicking "print preview" and actually printing
<rqou> and if you hit the race window all of your equations are all f*cked up
<rqou> and on top of this print preview still has some rendering differences
<rqou> not as many as exporting to latex, but still
<rqou> why is this software such a broken piece of sh*t
<rqou> ZOMG
<rqou> clicking print preview vs printing without clicking print preview also has rendering differences
<rqou> this is totally quality software that i wouldn't feel uneasy widely deploying in an academic setting /s
<rqou> three different settings, three completely different rendering outputs

<fouric> looooooool
<fouric> quality python software
<rqou> unfortunately raw latex sucks even harder
<rqou> and somehow jupyter seems to be accumulating all sorts of random features including not-python support
<fouric> "clicking print preview vs printing without clicking print preview also has rendering differences"
<fouric> ok, that's pushing it a bit
<rqou> oh yeah
<fouric> are you *sure* you didn't accidentally bop something lol
<rqou> if i click print preview some of my equations get messed up
<fouric> l'mao
<rqou> if i print without clicking print preview it still triggers the "print mode" stylesheet or whatever
<rqou> so you won't see the menu
<rqou> and the equations will be correct but code boxes will have half of the last line cut off instead
<rqou> apparently there's this weird hidden world of "scientific" software where everything sucks
<fouric> rqou: if you have a few moments would you mind saving this file + your jupyter version number
<fouric> i really want to see this
<fouric> i collect jank as a part-time hobby and this seems like it fits the bill
<rqou> sorry, you have to wait an hour due for academic integrity reasons
<fouric> I can wait however long is necessary lol
<awygle> that is an excellent idea for a hobby
<fouric> ...i know that that was meant to be lighthearted but i think it's actually true
<fouric> if you go around collecting bugs and edge cases and try to figure out why they're arising, you're bound to learn quite a bit about hardware/software
<awygle> no i meant it seriously
<awygle> although i was thinking of it as a shame-stick to beat companies with
<fouric> loooooooool
<awygle> it's like Jepsen for distributed systems
<fouric> hey, who says that you can't have fun, learn things, *and* help dismantle late-stage capitalism all at the same time?!? :DDDD

<pie_> i think i just got fucked by file system not syncing
wpwrak has quit [Read error: Connection reset by peer]
<pie_> more ram = less sync?
wpwrak has joined ##openfpga
<sorear> file buffers are flushed on an interval, and when unsynched data fills a large fraction of RAM
<pie_> then again theres no way things werent written to disk for 3 days so why is that file empty
* pie_ rages in despair
<pie_> also ran out of chocolate
<jn_> pie_: that doesn't sound good. what was supposed to be in that file?
<pie_> just the list of 20 pdfs i had open
rohitksingh has quit [Quit: Leaving.]
<pie_> when i run it manually it works ,dunno if the system runs it wrong or something
* pie_ sigh
<pie_> i set this stuff up specifically because i want to be able to continue relatively seamlessly after a reboot/crash/whatever
<pie_> it usually works
<pie_> but my tmux restore stuff is fucked up again
<pie_> last time it magically fixed itself and idk how to get it working again

<mumptai> did anyone bootstrap a icestrom system, i.e. synthesis running on a synthesiszed system?
keith-man has joined ##openfpga
<jn__> mumptai: i don't think so. i don't know any iCE40-based board with more than a few megabytes of RAM
<mumptai> is the picorv32 capable of running a linux? any mmu, supervisor mode etc.?
<jn__> i don't *think* it implements M-mode
<jn__> no
<jn__> s/M-mode/S-mode/
<jn__> that's what i meant
<mumptai> i guess a 256MiByte SDRAM could be done without too much pain
<jn__> and how would you interface it?
<mumptai> sdram
<jn__> doesn't this require precise timing?
<mumptai> four 512MBit by 8 bit
<mumptai> for a 32bit wide bus
<mumptai> nah, they can be run rather slowly
<jn__> s/precise timing/complicated timing calibration/
<mumptai> that is SDRAM with DDR tyle interfaces
<jn__> 256MiB would be rather nice
<mumptai> any other cpu small enough for hx8k?
<awygle> ZipCPU
<mumptai> capable of running linux?
<awygle> doubt it? they will probably answer more fully at some point, they're quite active on irc
<awygle> picorv32 is a better bet
<awygle> imo

<pie_> lol make a icestorm microkernel
<awygle> i suggested an icestorm accelerator core at one point
<cr1901_modern> I was able to fit ZPU onto a 1k
<cr1901_modern> Of course... it's ZPU.
<mumptai> ohh great, and ontop linux, and logic synthesis
<mumptai> sooo fast
<cr1901_modern> Linux on a stack machine, huh?
<mumptai> and it was probably one of the castrated zpus
<cr1901_modern> correct
<cr1901_modern> Half the insns were microcoded
<mumptai> and instruction fetch only from bram?
* cr1901_modern doesn't remember
<jn__> my favorite tiny CPU design is still J1
<cr1901_modern> J1?
<cr1901_modern> oh the forth thing
<cr1901_modern> I'll pass
<mumptai> anyways, zpu has no passable gcc anymore
<cr1901_modern> passable? I mean, the gcc provided w/ zpu still works
<mumptai> but no c++11
<cr1901_modern> oh
<mumptai> it is a gcc3.something
<pie_> pf. haskell for the zpu then we can talk
