Hi
We met with Renaud during one week in Lyon, France to work together on Kiwix. This was extremely efficient, we fixed a lots of bugs/feature requests and took many decisions concerning the further development of Kiwix.
Here is the wiki page: http://ur1.ca/9qzbs
We think this type of hackathon, like the informal one we had last year in Haifa, Israel is pretty valuable. We have the wish to organize one running on the same principles next year... maybe with more people and a little bit broader focus (offline meeting, people integrating Kiwix, openZIM, ...). In any case we still want to keep the concept of "planned hackathon", with list of tasks to do. So more a working week with people already involved in the offline than an open hackathon like we know them.
Regards Emmanuel
