I don't know how many of you are aware of this, but CodeChef - Online Programming Competition organizes an algorithm intensive programming competition extending over about 10-15 days every month. The next competition is coming up on the 1st of July and will go on till the 13th. As of now, only Indian and US citizens are eligible for prizes, but people from other countries are welcome to participate too Currently they are using SPOJ's(Sphere Online Judge (SPOJ)) systems as the judge. The quality of problems is pretty nice as well. They have about $3000 worth of prizes going out this time round. Hope to see you all there
