I'm a programmer and my machine runs up to 14 hours a day... ;)
Thoughts about SETI and SETI@home
Yes of course we are not alone! I don't think we find them yet but maybe in 100 years. What should we do? I think we make a lot of noice so we do not need to send anymore special... ;) Searching for moons from Jupiter takes a long, long time (9 years I think) before the first could be found. But if they don't start search, they don't find anything. So I think SETI@home is a good thing to help a little - because the computer runs anyway...
