The contest for this year is to write a program to print a frequency count in lexical order of all programs entered on standard in. This program should have no external dependencies, look reasonable, but should run much slower on one OS than another. Bonus points if the trick you use to do it can be passed off as a bad coding practice if you're caught.
Cheers,
Ben
