I keep myself gainfully employed to computer science related work. At the present I work for the Air Force Research Laboratory or AFRL supporting the local high performance computing (HPC) effort. That includes things like writing parallel codes with MPI, and building Beowulf clusters.
Aside from my work projects, I also have a lot of code from projects I have accumulated from doing school projects over the past seven years from my bachelors and masters degrees. You never know when you might need to remember how to a double linked list! It might take me a while to get it all sorted out though; I realized that I have over 1.5 GB of code from school.
