Well, I can put it all in a sentence: Euruko was fun!
The guys that organized the whole thing did a fantastic job for the ~300 geeks in attendance.
I enjoyed my talk on "rutema":http://patir/rubyforge.org/rutema , even while I panicked when I realized that the projector was showing 800x600 instead of the 1024x768 my slides were set for.
It was very nice to put some faces on names and I enjoyed the talks on JRuby, David A. Black's "per object behaviour on ruby" and "Synthesized testing" by my fellow greek George Malamidis.
"Grab the slides":http://www.euruko2008.org/pages/2-program while we wait for the videos.
And while we were at it, I got to fix a few bugs for rutema (never, ever update your gems before a presentation), check if it runs on JRuby (not there yet, but it's coming) and "release":http://patir.rubyforge.org/rutema064.html
