My main current* programming project is a GPS application for my phone, in Java, with Eclipse. I'm also helping my wife with her SQL projects.
In the past, I've done game programming (in C++ and assembly language), Windows testing (C++, C, assembly, scripting languages, etc.), NFS server testing (C, scripting languages), and assorted other stuff.
* In case I move on to other projects without remembering to update my "current project" status, this is what I was working on as of February 2013.
