Since the first Kitchen Hackathon was fun, we're doing the second one this Sunday (June 19th).
Again, the goal is not to be productive as such, but to introduce a few friends to what we do around Wikipedia, have a few beers, pizzas, enjoy the sun (we hope) and talk between techies. In the process, we might actually close a few bugs, but that's a side benefit.
That being said, if you know of some issue who might benefit from some more love during one day and that are reasonably easy to understand for someone without too much WMF background, send them my way!
We might have people who are familiar with Python, Puppet and PHP. And most of all that are ready to learn about things they do not understand yet.
Have fun!
