I was thinking about this, and I wondered if I might ask you guys.
How about starting a small problem marathon on Stackoverflow?
Basically, I post a programming related problem (original, not stolen from projecteuler), every day and people post solution the person to post the first, correct solution will be accepted.
And, it would be nice if people could upvote the accepted answer, especially if it was a really difficult problem. The problems will not be something like "Go write an APL compiler", instead, smaller pieces of code (nothing over 200 LOC in Python or something to solve). The problems also will not use anything that is not cross-platform (networking, GUI, etc.) Sometimes, I might post something that's tied to a particular language. Languages can be any, I know Java, C and C++ the most, so, answers in those languages are best reviewed (I'll try to find others to review them, however).
Would this be okay with the SO mods and stuff? Does the community think its a good idea?
If everyone is fine with it, then I'll post detailed rules and stuff.
