cr1901 changed the topic of ##yamahasynths to: Channel dedicated to questions and discussion of Yamaha FM Synthesizer internals and corresponding REing. Discussion of synthesis methods similar to the Yamaha line of chips, Sound Blasters + clones, PCM chips like RF5C68, and CD theory of operation are also on-topic.

joey 🏳️🌈 castillo sur Twitter : "one last artifact. Actually from inside yesterday’s thing. Remember these? PCMCIA cards. Technology from a pre-USB era. I guess dongles accomplish this now, but still, it was cool to add ports right there on the side of your computer.… https://t.co/vBvyBKB77w"
<whitequark>
heh
<cr1901>
Foone: Ngl, I did not know what DIVX was until yesterday :D!
<cr1901>
Apparently the codec named itself after the format as a joke
<Foone>
possibly. that is often reported but I'm not 100% sure it's been adequately sourced

>PCMCIA Pre-USB
<KitsuWhooa>
~if only usb was reliable~
<KitsuWhooa>
also, expresscard
<tpw_rules>
cr1901: remember mpeg cards?
<KitsuWhooa>
there were discrete mpeg cards?
<KitsuWhooa>
I've only seen asics bundled in graphics cards for DVD playback
<tpw_rules>
yeah i had a pcmcia one for my laptop
<KitsuWhooa>
huh, neat
<cr1901>
tpw_rules: I've seen ISA JPEG accelerators, but not MPEG ones
<tpw_rules>
i wonder if i still have it. i still have the laptop it would have gone into
<ZrX-NoMs>
I've got this PCMCIA antivirus accelerator.
<andlabs>
PCMCIA: the first wave of the IBM PC tech invasion onto other platforms
<andlabs>
followed swiftly by PCI and then USB
<andlabs>
of course

cr1901: divx is fun. one of my Stupid Dreams is one day crack at least one DIVX disc
<Foone>
it's not THAT hard, it's only 3DES. It still won't be happening any time soon, though
<sorear>
3des is pretty hard though
<Foone>
oh yeah. it's not simple, but it's within possibility.
<Foone>
you could currently build a small supercomputer and solve a given 3des in a few months
<Foone>
so I'm assuming that with improvements in computing power and algorithms, if I could solve it for a few months and 100,000$ now, in 10-20 years I'll be able to solve it for a reasonable amount of time and money
<sorear>
if my math is right 2^112 block calculations is 500,000 years of the current worldwide bitcoin network, assuming a 3DES test is the same as a SHA256
<sorear>
or are they using the weaker version of 3des
<Foone>
apparently with the Sweet32 attack you need 2^36.6 blocks
<sorear>
that's a data volume attack against CBC
<Foone>
yeah. with per-volume keys that's not going to be likely to work, because they're only like 5gb
<Foone>
but yeah the DIVX is proably not using CBC

Foone: i guess the keys were stored with the company?
<Foone>
yeah
<Foone>
delivered over modem
<sorear>
lots of DES-era stuff in finance and media has weird bespoke key management schemes
