Do you wonder if there is life anywhere else in the universe? I do! Do you want to find out? Is your computer often working, without really being in use? Then maybe you should join the SETI@home project!

What SETI@home is about

A group of scientists are scanning a large part (about one third) of the sky with a large radio-telescope from the Arecibo observatory. They're planning to keep that up for about 2 years. All incoming data is recorded in real-time, giving an enormous amount of tape with lots of noise. this has to be sorted out ofcourse.

And that's where YOU come in. The data that is recorded, is then split up in small packets of roughly 340kB, and these packets can be downloaded and processed by the computers of all participants. When you decide to join the effort, you first download a screensaver from the SETI@home homepage, and install it. After installation, you log in and collect your first packet of raw data. The screensaver will start processing it, whenever you're not using your machine. When the packet is completely processed, the screensaver will want access to internet to upload its findings and collect a new workload.

Background-mode, or how to get the most out of SETI@home

When SETI@home is up and running, double-click its icon in the system-tray, then click on "settings" and configure the program to work in background-mode. Also configure SETI@home to switch to blank-screen immediately when the screensaver mode is invoked. The advantage of this mode is, that each package is processed in much less time (up to 4 times as fast). A drawback is that the program uses quite some resources. If you own 400MHz (or faster) PC with 128MB of memory or more, you won't notice much under normal circumstances, but systems with less speed and/or memory may become a bit sluggish.

The sluggishness can be overcome, however:
If your system is not fast enough to comfortably work with SETI@home continuously running, switch to screensaver-mode when you're working, and switch to background-mode when you plan to leave your system for an extended period of time.
