Oh man... worst trips ever. Budapest to Paris. 2+ hours of boredom. Transferring at Paris. 30 minutes of rushing. Paris to Madrid. 2+ hours of boredom. You get the idea.
Highlights include arriving late for the train to Seville and missing the second plane on the way home, which meant having to spend a night in Paris (since it was the last plane flying to Budapest yesterday). At least the evening was well-spent, tracking the Hungarian elections live via SMS and drinking all-you-can-drink French wine.
I enjoyed last year's GUADEC a lot more: it was more organized and the talks were more interesting and exciting. I think this is partly due to the fact that for the most part of the last year, everyone was busy with GNOME 2, thus no new stuff was created.
Of course, the best parts were the informal discussions during breaks, lunches, walks, etc. One thing that delighted me particularly was when I was talking to DV and he said "So I see you're playing with XSLT?". He reads my diary and even remembers it!
murrayc had a talk on gtkmm, which looked quite bad at the beginning when it turned out that 90% of the audience had never used GTKmm before and most of them wasn't even particularly experienced in C++. However, later during the day lots of people were expressing their sorrow over missing it because of the Ximian party the night before -- having your talk scheduled against sleeping sure sucks. Also related to the C++ bindings: the Meekster mentioned it in his talk when speaking about the future of Bonobo -- so I guess now we're "canon".
