I went to bed around 9:30 last night. Woke a few times before waking up at 4:30. I woke up from a dream where I was visiting my university, and so I was lying there thinking about various professors I'd had. I got to thinking about one professor in particular. He taught CS, and I did a research project with him on robot programming one summer. I'd tried to look him up earlier this year because I found out that the company I now work for was the publisher of the book we used for that research project. I was unsuccessful; it looked like he didn't teach at my university any longer, but I couldn't find him. So, lying there close to 5:00, I couldn't get back to sleep, and I couldn't get this professor out of my mind, so I got up to google him. It looks like he's working at Intel, working on a project called Personal Server. I thought about emailing him, but I wasn't sure what I'd say, so I decided not to. Googling also turned up that he'd written a Java patterns book in 2000. So I suppose I could email him just to say hi and let him know that I work for a book publisher now. I really liked that professor, and I had a lot of fun with the research project. He'd designed this language for programming mobile robots, and we wrote a compiler for that language. We also built the robot, but the soldering and stuff wasn't all that interesting to me. Writing the compiler was where the real fun was. I should do more stuff like that.
