I have not thought about seti@home since I was at IBM. I put the new engine up on my machine, but, unfortunately, the servers aren’t sending out work today.

If you have a decent machine, you can use it to search for extraterrestrial Intelligence in its spare time. It automatically stops while you are actually doing something, so it is not going to effect your computing life.

What is SETI@home?
SETI@home is a scientific experiment that uses Internet-connected computers in the Search for Extraterrestrial Intelligence (SETI). You can participate by running a free program that downloads and analyzes radio telescope data.
