I gave two presentations at the conference. The first was about Polka, my humane address book for the cloud, which I mostly wrote during the last SUSE hack week. I explained the concept of addressing the problem from the user's side, not from an implementation point of view. Humans don't think about people in terms of vCards, but in terms of groups, pictures, time, and space. The Polka user interface reflects that.
I also did the first release of Polka during my presentation live on stage. So if you want to try it, go to the Polka home page and download the tarball. It's an early release, but it should work quite well. I intend to stabilize it a bit more and then do a 1.0 release. If you find bugs, please let me know.
The other talk I gave was a lightning talk in the Speedy Geeko session. Twenty slides in five minutes. This was fun. There were a nice variety of topics, including bees, fire fighters, and crazy scotsmen. My talk was about Maria Montessori, the Italian educator, who founded the Montessori schools. A lot of the concepts from her philosophy of education have interesting parallels in what we do in open source development.
There were many more talks. I only had a chance to listen to a few of them, but I enjoyed Greg's talk about the Kernel and Tumbleweed (change faster to be more successful), and Martin's talk about Wayland (wait until it's done, and then wait some more). Dominik showed the latest from SUSE Studio in a presentation and we also had the kiosk at the venue, which always is a great way to show, explore, and explain Studio.
Another great thing was that there were so many KDE people at the conference. It shows the strong relationship of openSUSE and its upstream projects, and KDE makes some excellent use of openSUSE, e.g. as base for Plasma Active. This is a great fit, and I think it's hard to underestimate how important collaboration between downstream and upstream is. We'll only win together.
