SETI@Home Version 3.0 Client Preview

Is SETI@Home Worthwile?

[Siqnal 11]

This is not a trivial question. Firstly, SETI@Home uses the Aricebo Radio Telescope. This is a very nice dish for radio astronomy, but useless for SETI work. It's far too small. The smallest useful dish or array will be the hectare array, being built by the SETI Institute. Aricebo will only be able to detect signals from nearby stars that are: (a) at LEAST as strong as our most powerful RADAR, (b) SUSATAINED for a substantial period of time, (c) containing information on a carrier wave, (d) orbiting a planet or star, with no compensation for motion

In short, leakage (the most likely sort of signal to be found) will be invisible, actual RADAR type devices will be screened out (too short a duration and no information content), and any civilisation advanced enough to WANT to locate other civilisations by sending deliberate signals are likely to be filtered, by being screened out as local interference through a lack of doplar shift.

Methinks that SETI@Home is ingenious, but is using the wrong telescope. And it'll be finished before the RIGHT telescope has been built & put on-line.

As for "Open Sourcing" SETI@Home, it was, to start off with. The original UNIX client was GPLed. Hardly anyone bothered to do anything with it, and so they closed the source & shoved it over to a commercial house. Don't blame them - look to yourself first.

Having said that, SETI@Home's attitude has been somewhat attrocious. They've been going on about security, when that was never the cause of them going non-Open Source. Progress was. And part of that is their fault. They refused to set up a CVS repository, did VERY slow (and low-quality) releases, and basically impeded themselves at every turn. They should have done a damn sight better than that. Yes, there were only a few people there, which is EXACTLY WHY they needed to use CVS, rather than relying on manually testing every e-mailed patch, and rolling a fresh tarball by hand every few weeks or months.

Honestly, if SETI@Home has shown anything, it's shown that we should be less worried about intelligence "out there" and rather more worried by the lack of it down here.
