  1. @kisasondi That's a pretty good page. You should go read it.
  2. @KevinSMcArthur You're a wanker.
  3. @kisasondi Entropy doesn't get 'depleted' like that.
  4. @KevinSMcArthur There's nothing whatsoever insecure about reusing entropy as long as you have a cryptographically secure RNG.
  5. @DLitz @deathtolamo Yeah, Fortuna is the successor to Yarrow.
  6. @damageboy Not joking, we got bitten by that one horribly.
  7. @kisasondi urandom is just as secure as long as there's enough entropy in the pool. Blocking for mix-in makes it more vulnerable, not less.
  8. @deathtolamo Linux *should* use Yarrow, like FreeBSD does, but it doesn't.
  9. @deathtolamo Here's some info, it's a real disaster - web.archive.org/web/2008100304…
  10. @kisasondi Because /dev/random blocks completely unnecessarily.
  11. @KevinSMcArthur If there's enough entropy in the pool there are no problems.
  12. @deathtolamo It's cryptographically secure, no problems with mere statistical tests.
  13. @eqe @nadiah That's a faulty /dev/urandom. It should block until it gets an initial pool.
  14. Do not use the random access flag! It will cause the cache to never be flushed! fb.me/U3wnnA3V
  15. /dev/random is for wankers. Use /dev/urandom instead.
  16. Hex on the 8x8 board has been solved. fb.me/1UCrhnGYz
  17. My new invention: A connection between a car and a phone, so the phone has access to the car's GPS, compass, and accelerometer.
  18. @mm The Wall Street guys didn't make a whole bunch of money. The horror!
  19. Can someone explain to me what qualifies Ross Levinsohn to run Yahoo? facebook.com/bram.cohen/pos…
  20. @rchen Yeah, a time machine to go back and accept that Microsoft offer. Dumbasses.
