Google is challenging you to prove yourself! If you are a programmer (noob, pro, and anything in between) you might wish to accept the challenge and participate in this year's Code Jam.
Google Code Jam is a yearly global coding challenge organized by Google since 2003, in which you can use any programming language you like to solve some algorithmic problems which can range in complexity from easy (Qualification Round) to min-boggling (Finals) eg: this challenge one in 2010, which no one managed to solve. According to the official Google blog, "last year’s champion, Makoto Soejima, was asked to build a house for kittens, serve food to hungry mathematicians, escape from a shady casino and help Goro control his anger."
