 <p>
 Hurrah, I've just contributed my first code back to the <a href="http://trac.edgewall.org/">Trac</a> project. I've created a workflow for the 0.11 release which adds a simple "testing" state to tickets before they are closed. For the Trac addicts amongst you, it's available at <a href="http://trac-hacks.org/wiki/TestingWorkflow">Trac Hacks</a>. I'm rather proud of it, because it's actually the first workflow hack on the site!

 Since January, I've worked at the [Open Data Institute](http://www.theodi.org), which has been a really great experience. As well as being a non-profit with a mission to make the world better, which is already a huge win as far as I'm concerned, the organisation also puts a massive emphasis on culture and people. For a small enterprise (less than 20 people), this is amazing, and I've never seen anything quite like it anywhere I've worked.
