SETI@home still looking for aliens, finds missing laptop
Software programmer James Melin's wife's laptop was stolen in January. It also happened to be one of 7 computers that Melin had installed the SETI@home software on.
Well, it turned out the thief never bothered to disable the software, and so within a week it shared data with the SETI@home server three times. Melin gave the IP address to the police, who were able to get a an address where the computer was being used from a local intenet service provider, and the laptop was returned.
Melin's wife was duly impressed.
