What is SETI@home?
SETI@home is a scientific experiment, based at UC Berkeley, 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.

20 years and counting!
Happy Anniversary! On this date in 1999, SETI@home came online. Since then millions of our volunteers have helped us sift through petabytes of data from multiple radio telescopes. ET still hasn't shown up to the party.
We're not discouraged. We're able to examine less than a tenth of a percent of the radio spectrum, over only 1/3 of the sky and a limited number of additional stars. But our capabilities are increasing every day. In 1999 it took up to a week to process a single workunit on a home PC. Now, on a machine with a GPU, it might only take a few minutes to do a far more detailed and more sensitive analysis. Who knows what the next 20 years will bring?

Long Outage Today
We had to recover the master database on oscar from a backup taken today on carolyn. Oscar is now back to being the master DB and carolyn is once again the replica DB. Things will be a bit slow as the database becomes resident in memory.
