  3. @xtoddx i like dragonfly bsd quite a bit! been a while since i've done any BSD kernel hacking.
  4. @ninh yup. we have some interesting ideas but no spoilers just yet :)
  5. breakthrough: loaded the heap from a core dump from a ruby process into a *different* ruby process, and pointed the ruby internal heap at it
  6. Weight belt wrapped around your face is hardcore http://yfrog.com/33yapmj
  7. at the gym earlier today i saw a guy lift weight with his face.
  8. @ninh gcc does change switch statements to jumps, but that is not what this optimization does.
  9. managed to trampoline an inlined function. it is now getting serious.
  10. @romannurik yup, back in late 07/early 08 if i recall correctly.
  11. @romannurik sorry to say it, but that is like super old news bro.

  17. @fmarmond using what i did i can see what ruby source file and ruby source line an object was allocated at, which is pretty useful.
  18. @fmarmond yeah but that doesnt work well enough for ruby land, is the problem.
  19. @fmarmond malloc_hook wouldn't have helped. i wanted to see where in ruby land objects were getting allocated.
  20. Thanks for the RTs & upvotes every1. Each time I post a new blog entry I'm humbled by the all the RTs & nice comments. Thanks for the love.
