I have recently begun participating in the TopCoder 'Arena', where I've made some code that could be of absolutely no monetary value to anyone (except to me, as training). Actually, it's a lot of fun.

Still, I wonder about this company.

It has some connection to the NSA, as advertised on their web page and elsewhere. Does anyone know more details about this relationship? In particular, what does the NSA aim to get out of it?
