You may or may not have heard of Eventum… it’s an issue tracking system that MySQL AB uses to manage its technical support.
Eventum’s history in a nutshell:
It was written by Joao Prado Maia, and it was already looking rather nifty before its first official release! However, MySQL support needed more, and nothing else came even close to being suitable.
After some talks, Joao and Eventum both joined MySQL AB, Joao continuing to work on Eventum (now joined by Bryan Alsdorf) and Eventum was released under the GPL license.
When doing talks at user groups and conferences, recently I’m often getting feedback from users who tell me that they use Eventum for their own internal or external needs, and that they really like it!
So that’s great news. Of course, systems such as these are always subject to your individual requirements and also your way of working. It may or may not suit you. But if you’re interested, do take a peek.
