I know there are a number of us who code, at least for fun. Most of the coding I do now is stuff that interests me. A couple years back, I wrote an app to compute the molad, today I installed Ubuntu and did a command line base-to-base conversion, bases 2-36 (strictly with vi). I know there's some reinventing the wheel here, but the point is to think through a rather simple problem, and code it.
A year or so ago there was an interesting problem in the Math thread that I coded on CppDroid (way too hard to use), but I was hoping we could share ideas on a dedicated thread.
Any programming questions should be directed to stackoverflow or the like, not discussed here.
