Well I just program only really. I mainly freelance code for webmasters.

Text Editors (for code editing)
* BlueFish
* Vim
* Screem


Browsers/Compiler (for viewing the results)
* Mozilla Firefox
* IE (wish I could, for testing, but I can't run it on Wine on Linux and I haven't fixed the problem on my Windows drive because I'm just lazy )
* Opera (haven't installed it yet though)

CVS

LAMP (Linux Apache MySQL PHP)

Graphic Editor (occasionally, for web graphics)
* The GIMP
I wish I could get Photoshop
* Inkscape
