  1. @nk @lg we just figured something out that will make us all feel stupid tomorrow.
  2. @fennn just for the week :)
  3. Reading, writing, and debugging x86_64 assembly at @twitter
  4. added backtraces to ltrace so you can see where your shit is getting called from.
  5. i really like libunwind. it is really easy to use and even provides ptrace callbacks for me.
  6. fun day hacking with @tmm1 @nk and @lg at the @twoffice
  7. @igrigorik official devs or people who hack on ruby vms? if the latter i know two :)
  8. @bmizerany @rtomayko disas that shit
  9. @jnewland you can also just use ltrace or strace.
  10. who else is hiring for ruby/C in SF? (via @jakedouglas)
  11. @bmizerany fuck yeahhhh im not scared
  12. my skull is not functioning properly but i THINK this is the earliest i've been awake in SF... ever.
  13. wow some one actually used my force_dca hack. cool.
  14. asm("int $0x3\n") is the single most useful line of inline asm. if you know no asm, commit that line to memory asap.
  15. @vhokstad it does. -dbg packages.
  16. @aryaasemanfar ofc you sacrifice portability, but very worth it, imho.
  17. @aryaasemanfar yeah but polling is no fun :) using netlink and connector you get immediate notification when your app dies thats >>> polling
  18. @aryaasemanfar to get asynchronous notifications of when processes fork or die. way better than polling over and over.
  19. @aryaasemanfar does bluepill have support for connector?
  20. I just really hate when things segfault and I cannot gather a useful backtrace to fix it. Maybe I can convince debian to stop stripping bins
