This year was a completely new experience for me. I've been visiting devoxx (and javapolis before) since I was a student. I know I skipped one year since then and that's probably it. Most of the t-shirts I still have. Some are gone though (too bad).
This year however I was on the other side. I was able to work along with the devoxx team! I'll get back to this post soon with more information of what I really did and how I experienced that. Need to recover first.
Talking about robotics and the future track of Devoxx. My ArduPilot session got a lot of attention. The BOF room was completely full and I didn't see much people leaving during the talk either. I had a flight instructor on the front row. Great to have some interaction and to be challenged! Too bad my demo failed at the end. I had everything with me twice so I could always use the backup instead. However I ran out of time before I realized my gear was not working and I needed the backup.
The NFC/Arduino/Raspberry PI/NodeJS project was also a success. We handled over 10k votes with this system. Still a few bugs to fix for Devoxx 2013. We're on it!
