As it turns out, a good fraction of science is computer programming and scripting. Some of my scientific software is online for public use. I have much more than this (including some very lengthy codes to do detailed modeling of GRB light curves and of GRB and SN photometric SEDs) that I would like to make available during the next year; please ask for details if you're interested.
Astronomical image processing:

Autoastrometry (Fully automated Python astrometry solver)

pzap (Cosmic ray remover for imaging)
