This is an old picture. I think I was 23 in the picture. It was taken at my sister's wedding.
Thoughts about SETI and SETI@home
1. Yes, I think it is highly likely that extraterrestrial life exists. In all honesty, I do not believe humans will discover it in such a dramatic way as Hollywood depicts. It seems a lot more likely to me, humans will eventually travel to another planet outside of our solar system. The first life they might encounter on such a trek is more likely to be a simple organism as opposed to inteligent life. But I still believe inteligent life exists. I just think it will take much more time to discover due to it's likely rarity.
2. Yes, humans should transmit a beacon. I think the movie "Contact" had it right, the beacon should be something simple like prime numbers transmited in pulses (similar to the way radios send morse code, continuous wave, CW).
3. I got into seti@home in 1999 when a friend mentioned it to me. He then e-mailed me with the link and I started processing work units. Nothing too exciting about that. But I am very impressed with the whole concept of shared computing power. Since my computer is almost always running (a vast majority of the time spent idle) I figured I would give it something to do.
