I'm a mathematical physicist expecting to finish his Ph.D. this summer. I'm not having any luck with academic positions, so I'm getting ready to try industry. Note that I am not at all sure what kind of position I want. Finance? Sure. Consulting? Yeah, why not? R&D somewhere? Yup. BUT...my computer skills are, I think, pretty underdeveloped. (In fact, one of the reasons I went after academia in the first place is that my computer skills seemed too crappy to land a nice industry position; I think industry is a better fit for me than academia anyway.) I've used Mathematica a lot, but it doesn't seem very many people care about that. So what should I do? I took a class on C in college and did very, very well, and so I suppose I could (and probably should) brush that off a bit...but what else?
