It integrates with existing Subversion repositories; for example, you can browse the code in your repositories with Trac (it'll be displayed syntax-highlighted), view diffs between revisions etc. etc. Additionally, you get a wiki (e.g. for project documentation), as well as a built-in bug-tracker a la Bugzilla, all integrated nicely into a single piece of software...
It's Free Software, of course (the license changed from GPL to revised BSD somewhat recently)...
A few words on the installation:
apt-get install trac.
trac-admin /path/to/environment/myproject initenv. You'll be asked where your svn repository resides, what's the name of the project etc.
/path/to/environment/myproject/conf/trac.ini, and change the header logo/URL, the default component/priority/issue-owner and more.
trac-admin /path/to/environment/myproject. Type "help" for um... help.
So far I've set up ca. 7-8 Trac instances for various projects and I'm quite happy with it. While I was at it, I also created a tiny Trac article in the German Wikipedia.
You might have already noticed, but I'll re-iterate nevertheless: the Drupal project has released Drupal 4.6.4 and 4.5.6 which fix three security vulnerabilities. Everyone running a Drupal site is advised to upgrade, as always.
Multiple people were mighty busy yesterday preparing, finalizing and testing the patches and advisories. I was one of them, although I was more like lurking around trying to look busy ;-) Anyways, I have sent the respective advisories (DRUPAL-SA-2005-007, DRUPAL-SA-2005-008, DRUPAL-SA-2005-009) to the "usual suspects" today: Bugtraq, Full Disclosure, and the php-sec mailing list. The advisories have already been picked up by Secunia and a bunch of other security sites...
Btw: I finally received news that my domain was transferred to my new web hoster today, which led to a short downtime. Everything should be fine now. If you notice any problems, please drop me a note.
Looks like Google and Odeo are getting some competition.
OMFG! Only yesterday I said there's no really nice Flash website out there. I might have to reconsider.

The annual report from usability expert Jakob Nielsen:
I agree with all of them, especially number 3 (Flash). I'm starting to like most of the AJAX sites popping up around me, but I have yet to find a Flash site which I really like.
