Bits of Wisdom

You know when your program is useful when you spend more time using it then developing it.

Don't free all your malloc's.  Free is a very expensive code no matter how you measure it, and the OS will take care of it when your program exits.  If you aren't coming close to running out of memory, let it leak 'till the program exits and let the OS do the work.  It will make your program run up to ^x16 times as fast.
