Let's see...

* Javascript (+jQuery and MooTools) / HTML / CSS
* PHP (+ Smarty), Perl
* Apache / Lighttpd, MySQL
* general Linux administration (it helps that I'm a full time Linux user)
* Java
* Bazaar
* Make
* XML parsing
* general lexing and parsing (surprisingly how often it comes up, and how few programmers are able to do it)
* database design
* basic mastery of bitmap and vector image editing, sound editing and video editing and transcoding

I'm probably forgetting a few things, but these cover the basics.
