Agree with your good suggestion, and extend with rosalind.info for kinda the same experience but for bioinformatics instead of math. Now what I'd be VERY interested in is an implementation of a list of "Like Project Euler, but for X" where X is all manner of things. WRT various values of X, I know there are periodic security challenges but nothing long term/permanently ongoing, I'd greatly enjoy being proven wrong. I'd be particularly personally and professionally interested in "Project Euler for HFT". How about "Project Euler for VLSI design"? Yeah, yeah, If I want it, I should do it, and its true I probably could, other than the lack of infinite spare time.
