The Windward Collegiate Programming Cham
- the first intercollegiate programming code war, with multiple teams competing from most of the top computer science colleges in the country. We have invited the 22 schools that appear on the various top 10 lists and so far CMU, Cornell, Illinois, Maryland, MIT, UMASS, Harvey Mudd, Purdue, Stanford, Univ of Toronto, and Wisconsin have accepted while 8 others are considering it.

another set of challenges
- Facebook runs a continuous set of graded programming challenges, mostly as a recruitment tool. but obviously they can't force you to work there if you don't want to. www.facebook.com/careers/puzzles.php

Bitwise 2010
- Bitwise is a state-of-the-art online programming contest. The contest is time constrained and posed with some of the toughest programming and algorithmic challenges in a short span of 12 hours. Bitwise was started in the year 2001 by the 4th year undergraduate students of CSE Department, IIT Kharagpur. The contest provides programmers across the globe a platform to compete and test their abilities to develop efficient algorithms for engrossing real-life problems within a given time constraint. Over the last five years, the contest has become extremely popular around the world. In Bitwise 2k9, over 3000 teams participated from over 50 countries. Registration is free and open to all. Contestants need to solve a set of problems posted on the site using C or C++. The solutions are evaluated, not only on the basis of correctness, but also on their execution time and space complexities(FAQs).
