Controlling fps with requestAnimationFrame?
...ling at 5 FPS: http://jsfiddle.net/m1erickson/CtsY3/
This method works by testing the elapsed time since executing the last frame loop.
Your drawing code executes only when your specified FPS interval has elapsed.
The first part of the code sets some variables used to calculate elapsed time.

Why does GCC generate such radically different assembly for nearly the same C code?
...
This is the nature of compilers. Assuming they will take the fastest or best path, is quite false. Anyone that implies that you don't need to do anything to your code to optimize because "modern compilers" fill in the blank, do the best job, make the fastest code, etc. Actually I saw gc...

Modern Java is one of the fastest languages, even though it is still a memory hog. Java had a reputation for being slow because it used to take a long time for the VM to start up.
If you still think Java is slow, see the benchmarks game results. Tightl...
Why does NULL = NULL evaluate to false in SQL server
...f NULL you think of “NULL” (string) then you probably want a different test of equality like Postgresql's IS DISTINCT FROM AND IS NOT DISTINCT FROM

Why would you use an ivar?
... CFAbsoluteTimeGetCurrent();
for (unsigned i = 0; i < kRuns; i++) {
testIVar = i;
}
cft = CFAbsoluteTimeGetCurrent() - cft;

cft = CFAbsoluteTimeGetCurrent();
