>From Jim Getty's page on Wikipedia:

"One of his main goals at OLPC was to review and overhaul much of standard 
Linux software, in order to make it run faster and consume less memory and 
power. In this context, he has pointed out a common fallacy among 
programmers today: that storing computed values in memory be preferable to 
recomputing those values later. This, he claims, is often false on current 
hardware, given fast CPUs and the long time it takes to recover from a 
potential cache miss."

I remember this talk early on in the OLPC project. Has anyone checked this 
in relation
to things like sinusoidal oscillators etc? In the case of commom maths 
functions are we
still winning by using table lookup?
