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.

I was dropped off at birth on this backwater planet called Earth. It is inhabited by many forms of life including a dominant form of sentient being...


Low available work.
For a couple of reasons, the result table has grown to the point where it no longer fits in main memory. That has been slowing the validators and assimilators, which is causing the result table to grow further.

We'd like to get it down to a manageable size before our Tuesday outage. To that end we are throttling work generation to a rate at which the table size is shrinking. We hope that this rate will increase as the table gets smaller.

So for the next few days work will be hard to come by (but not zero).

Why do people run SETI@home?
Check out Stars in Their Eyes?, a research paper from the University of Geneva about why people run SETI@home.

Some server issues today...
It's the Friday before a holiday week and the servers know it.

The file system containing the beta project uploads directory is having problems, so beta is down until further notice.

This problem may be affecting the rate at which the main project can handle results, so the validation and assimilation queues are getting large, which may affect the rate of work generation.

New paper on observing "Clarke Exo-belts"
Dr. Korpela and his colleagues Prof. Shauna Sallmen and Ms. Kaisa Crawford-Taylor have published a new paper today in the Astronomical Journal about whether astronomers be able to detect belts of satellites circling planets around other stars. Unfortunately, the answer is that even the thickest satellite belts will be very difficult to see with current technology. Even the James Webb Space Telescope will find it difficult.

If, like most sentient beings in the Galaxy, you don't have a subscription to the Astronomical Journal you can see a preprint of the article at arXiv.org.
