A fun post on how to apply many concepts in computer science into your daily life.

The skills you need are your intelligence, cunning, perseverance and the will to test yourself against the intricacies of multi-threaded programming. Each challenge below is a computer program of two or more threads. Your objective is to exploit flaws in the programs to make them crash or otherwise malfunction.
