Challenges, Puzzles and Courses in Maths, Logic and Computing
December 12, 2015 1:58 PM   Subscribe

I'm looking for challenges, puzzles and "teach yourself" courses that involve maths and logic, probably related to computing. Ideally I'd like a curated source (mailing list or regularly updated website), but perhaps the best we can do is collect them here. Inside I will give examples of what I mean by "challenges, puzzles and courses".

Thinly-veiled recruitment is fine, but I am looking for something more that online education (like Coursera). There should be a puzzle, challenge or competition aspect, and it has to be free to enter.

IBM Research publishes monthly puzzles. For example, this month's challenge:

"Find a formula to convert the 52 EBCDIC letters into ASCII using no more than 4 operators."

Also, the top post on HackerNews right now is Stockfighter, which launched today. Apparently it's somewhere between a CTF and a stock market simulation.

This is a little outside of what's your looking for, but consider trying some LSAT practice tests, specifically the logic games.
