Thank you Matt, David A, Dan, Jeff, Josh Von Korff, Robert Bankay, Kevin Douglas, and anyone I forgot.
You scientist At SETI@home show outstanding dedication to keep this project on line. Best wishes and peace Byron.

Because there's no tapes to split, and so no work to download?, Setiathome has only been going for just over 11 years!, because you're using a new account, and haven't linked your classic account to it?

I sure like to hear, what's going on in-- and how the Project makes progress.

Can only agree with Byron.

Gotta remember, the folks @ SETI are working on fixing problems, they look in from time to time, however right now they are more worried about fixing the problems they had over the last few days. Hang tight, I'm sure one of the crew will post eventually. Matt has gotten a bit burned out from doing it daily, Eric posts every now and then, the others I don't know. I know many folks want to be kept up to date on whats happening behind the scene's, me personally, I'd rather them fix the problem, then tell us what happened after the fact, not while they are in the middle of trying to fix things. The longer it takes them to fix things, the longer the project is down.

Thanks for all the hard work put in. Just a question: Has anyone modeled what we would sound like, say, a million light years away? The earth is rotating, moving around a star moving around a galaxy, and antennae are purposely designed not to propagate omnidirectionally (favoring instead the intended audience direction) a listener would only hear many of them when they happened to be tangentially located, that is on the horizon of Earth with respects to their Arecibo. What would we actually sound like?

... Has anyone modeled what we would sound like, say, a million light years away? The earth is rotating, moving around a star moving around a galaxy, and antennae are purposely designed not to propagate omnidirectionally (favoring instead the intended audience direction)

The effects of "dispersion" of a transmission propagating through space, and of "Doppler shift" due to the Earth's trajectory and rotation, are all included as part of the seti search. That's what all the 'dechirping' and FFTs are all about.

However, the possible search is so vast that we must make assumptions that ET want their transmissions to be found. From that, we can then make a very much smaller search to look for transmissions that are purposefully intended to be found.


a listener would only hear many of them when they happened to be tangentially located, that is on the horizon of Earth with respects to their Arecibo. What would we actually sound like?

With our present technology and understanding, and following the example of how our terrestrial transmission technology is developing, we simply would not hear anything.


For our own transmissions, it might be possible to detect the various high power military and interplanetary radar transmissions many light years away. The most powerful is Arecibo's radar!


Keep searchin',
Martin

You're welcome, and welcome to the biggest search on earth!

Don't be put off by the various transient data supply problems. The (remarkably few) people at Berkeley are juggling vast amounts of data on a workload that is a Distributed Denial of Service attack for most systems. All on a whole load of Frankenstein bolted-together and donated servers that would make for quite a reality-TV spectacle!

Regardless, the Science is still good and there's many aspects to the experiment, including us...

There is very serious Science with the search and analysis algorithms. An important part of that is with Berkeley getting the "Nitpicker" up and running. Boinc itself is an experiment on how you can run a vast compute project on minimal resources, such as s@h...

And Boinc is designed for such hiccups, hence the option of selecting 'backup' projects or sharing resource with other projects so as to stay usefully idle.


Keep searchin' and Happy Crunchin'!

Regards,
Martin


Ooops... The forums are the "Reality-TV"! ;-)
