As seen, many tricks and some technics are found and used in Algorithmic Competitive Programming. They don't have enough academic value for lack of induction, abstraction, theory or application. But these are still of some use, especially for juniors and young students before entering university.

These materials are everywhere on the Internet, from blogs to contest tutorials. Maybe some of the below could help?

• An index for current important materials, organized by categories in CS and Competitive Programming.
• An electronic journal (like IOI's and CCF-NOI's) for these toys. (To take place of those boring training courses in college, maybe.)
• A global discussion platform (like AoPs or StackExchange?)

Please comment if you know any of the above existed.

I'm just discussing the probability :) Thanks!
