Seriously, Should I come back to SETI

4000WU's. I finally got mad and left the program when I felt SETI was
rewriting their software to slow down users. They said that they were going
to get more science out of each WU but I felt they were slowing everyone
down because of limits in their servers. If I come back, are we doing real,
productive, science or are we waisting electrons. Thanks for reasonable
responses.

to slow down production. The first clients looked for Gaussian patterns
almost exclusively but the new clients have to extract Gaussians, Pulses,
Triplets and Spikes. They are also doing more detailed scans of the data.
As soon as we are online in the southern hemisphere we will have more work
than we can handle.
If they were truly worried about not having enough WU's to go around they
would not have disconnected from Arecibo.

Seti have tried to balance a lot of things. The greater than expected number
of volunteers has allowed the same amount of data to be processed at least
twice (as in any worthy scientific experiment) and allowed the search to be
widened. Since we don't know where to look, looking in more places because
there are more volunteers with better CPUs can only be good.
At the end of the day you are a volunteer, so you have to make up your own
mind.

Not using a personal computer for a noble scientific cause is wasting
electrons.

I've heard talk that they are widening the research by
a factor of 20 (looking at more of the electromagnetic
spectrum) and will be getting feeds from another radio
telescope in the Southern Hemisphere.
We have all felt a bit of frustration in the past as
this project cranked up, but even the originators never
expected *this* much help. Speaking just for me, I can
cut them some slack. We are only humans, after all...
If there was another project even close to S@h for both
Science and my personal interests, I might go there. I
refuse to make some company richer on my volunteer
efforts, though, or make some government snoopier.
If you come back, welcome back. If not, please let us
know of any project more worthy; I might go with that.

mean that it will take 20 times as long per WU or will they WU be split up
so as they take the same amount of time as they do now.

Now that I'm aware that I can talk about it, I suppose I could fill everyone
in on the current direction things are going (colored a bit with the direction
I'd like them to go).
The first big thing is that observing at Parkes will be different than at
Arecibo. We'll be tagging along on the primary receivers, so we won't be
slewing across the sky like we do at Arecibo. Gaussian fitting goes away
in this observing mode. On the other hand we're on the same spot of sky
for longer, so we can bump up max FFT length to 256k and look at even
narrower bandwidths.
The current plan is for a workunit to still be 1M samples, but to frequency
step across the workunit. The first 256K samples will be at in one frequency
band. The next 256K samples will be in a band 2.5 MHz higher. So in essence
each workunit will cover about 40 kHz rather than the current 10 kHz. Going
to 256K will increase processing time an as yet undetermined amount.
I'm pushing for the new client to be capable of processing Arecibo work
units, so I'm hoping that we'll still keep looking in the north without needing
some people to keep running the old version of the client.
We're still nailing down the details. And we haven't even started client
development at this point. (We're pretty strapped for cash right now, too.
A lot of our funding sources are feeling the economic pinch and some
donations that were to be matched by the university haven't (yet) come
through. So if anyone has some loose change...)
Of course, we send our thanks to those who have given cpu time, advice,
money, equipment, etc.

same size, just more of them. Lets not forget the Southern hemisphere and the
ASllen Array also. Could have enough work for years. Buster

Eric, can you give us a rough idea when we may see some of this
coming down the pike - the new software, the new workunits,
etc... Thanks.
