If you can find an algorithm(source code in JavaScript or C(i dislike debugging complex C code, but i like to write low-level bithacks which require C)) where
1.Performance is ultimate concern
2.Algorithm can be tested many time per hour
3.Its provides a useful effect,feature or some other result which depends on performance.
I'll copy it to my script folder and optimize it,
if it works better, i'll post it on /prog/ and my subreddit.
