Tools stumbled upon…
S5 Web-based powerpoint replacement
I've been replacing Microsoft tools one by one lately... IE was replaced by firebird ages ago. Second went Outlook, replaced by thunderbird (and sunbird... sorta, I don't do much calendaring as a student). Then, I taught myself the Latex typesetting system to replace Word. For class, I started using Matlab... I'm starting to think that can replace Excel.
Trac project management
Trac looks interesting for project management. It combines wikis, a ticket management system and source code control. I recently installed subversion to keep track of assignments... pretty cool... I use TortoiseSVN, a windows shell extension, to check documents in/out of the subversion repository
Winamp
This isn't really new to me... I got tired of itunes. Actually, I take that back. I love itunes. I hate DRM. I used hymn to unlock all the music I bought on itunes (over 700 tracks) and then imported all my music to winamp's library using this tool. Plus, with this plugin, I can manage my ipod in winamp. I still have itunes installed, but for how much longer?
Audioscrobbler
Nice for finding new music... Hard to describe why, but I love this site.
password generator
Clever little javascript for managing passwords... I use it for every site I have to login to.
Greasemonkey
Here's another one that's hard to explain, but that I really love. Basically, this tool (for firebird) allows you to edit others' webpages at will. Look here for some cool applications of the tool. Among others, I have the amazon2melvyl and google scholar monitor scripts installed.
