Feb 13, 2012 at 12:00 comment added petrichor +1 This is a very nice question, but do I miss something? The answers involve mostly links to some challenging data sets and open courses. On the other hand, ProjectEuler consists challenging questions of different levels and you increase your skills while you solve them. And you can see the others' solutions after you solve the problem. It is similar to pythonchallenge.com I think. Are you asking something like this? A clarification would be very nice.
