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.

lol - i just presented it in class 1 hr ago! but, as you correctly point out
- it's the concept which is valid, if not the implimentation.
ps. presented hoe too.
cheers.

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

We have not succeeded in answering all of our questions.
In fact, in some ways, we are more confused than ever.
But we feel we are confused on a higher level and about more important things.
