Sorry for a bit belated post. I attended GUADEC this summer, in Strasbourg, France. This was my second GUADEC and it was again a great experience.
The keynotes were inspiring and the status updates on GNOME core components were really insightful. I particularly liked the Cheese, Documents/Photos, and GTK+ talks, as I learned a lot of new concepts, along with the ideas behind them. I also found the Python and GNOME talk thought-provoking.
I presented a talk on input-method. It mainly discussed smart input-method features which can be found in other platforms, while exploring ways of improving the current architecture. Afterwards, I had nice chats with Aron and William, working on the same area.
On the BoF days, I was planning I18N BoF, which ended up as a random hacking/chatting session. Sorry about that, but it was fun and there were interesting discussions about translation tools and spell checking.
