you know those threads where someone posts a bit of slow ruby code, then
people rework it until it’s orders of magnitude faster?
what’s the BEST one you can remember?
thanks.

I liked the one I posted with my writeup of making png.rb faster with
RubyInline since Dominik (sp?) gained similar speedups with pure-
ruby. I think the pure-ruby speed-up ended up within an order of
magnitude of the selectively-optimized RubyInline version. Instead
of making the operations faster, Dominik changed the data structures
slightly for speed to reduce work.

I tried to apply dominik’s changes and the problem was that they
broke a lot of stuff. I don’t see his numbers as being entirely
valid, but his approach was.

Sorry for being completely OT but it just stroke me:
Do your students know to read the ML before the exams?
Cheers
