The Foul Side
Some of you may have noticed the ~11 hours of intermittent downtime that codekoala.com experienced from early on the 24th of January to just a little while ago. I was doing some work on my django-tracking application, which somehow seemed to break my site. CodeKoala.com uses PostgreSQL as the database backend, and as soon as I tried to apply the changes to django-tracking to my site, everything just seemed to die.
The weird thing was that the site would work if I put it on a sqlite or MySQL backend. I didn't change the database schema at all as part of my changes to django-tracking, so it made absolutely no sense. I was in touch with WebFaction's awesome support squad for a good deal of today trying to get things sorted out. We tried just about everything we could think of, short of porting the entire site to a different backend or restoring a recent backup.
Just as things were looking very grim, I tried this command: ./manage.py reset tracking. Voilà! The site started working again. I guess I just had some super funky junk in my tracking application's tables.
On the Brighter Side
As a result of all this work and toil, you all can now enjoy django-tracking 0.2.7! There were a lot of minor code optimizations that went into this release. The biggest change, however, is the fancy "active users map" that you see here.
This feature allows you to display a map of where your recently active users are likely to be based upon their IP address. A list is also available below the map with displays further information about each active visitor. The page updates itself every 5 seconds or so, which means that if a visitor hasn't been active for 10 minutes (or whatever your timeout happens to be), their marker will disappear from the map and their entry in the last will go away too! Pretty dang fancy if you ask me!

So folks!! Please play with it!
