To my loving girlfriend, Anne-Laure, who once again put up with entire evenings and weekends spent on my PC. This is the second time I've done that to her, but she put up with me anyway and kept on smiling (most of the time). I still don't know how.
To my wonderful daughter, Eléna: I have to admit, I'm addicted to your laugh and smile, something you did every time I showed you the projects I was working on. Again you found a way of telling me when I needed to stop and spend more time playing with you (by unplugging and randomly rewiring my breadboard projects), but coming back home at the end of a long and difficult day to see you smiling and jumping into my arms gave me more energy than you can imagine.
