I am a general geek. I use Linux and Windows, and have some knowledge of UNIX in general, as well as more specific knowledge of BSD, Mac OS and Mac OS X. I know C++ and Java, although I'm not highly skilled in either. I also know a little of several other languages, usually enough to understand the general idea of code, albeit not enough to write it.
I use KDE, Amarok, Blender, The GIMP, Inkscape,OpenOffice.org, &c.
I love userboxen, but organizing them in some way which makes sense is impossible.
