500-fold Increase in Data Flow from SETI Telescope 346

coondoggie brings us an article from Networkworld about a flood of new data for the SETI@home project. We discussed something similar a few months ago when a new telescope array went live. The vast amount of processing power required to handle the new data is prompting the SETI@home team to make a plea for more volunteers. Quoting the press release: "What triggered the new flow of data was the addition of seven new receivers at Arecibo, which now let the telescope record radio signals from seven regions of the sky simultaneously instead of just one. With greater sensitivity and the ability to detect the polarization of the radio signals, plus 40 times more frequency coverage, Arecibo is set to survey the sky for new radio sources."

    I thought they were going to shut down Arecibo or move to an array of smaller antenna's or something? Did the plan change or am I making this up?

    I'm just curious how much energy the SETI project has used with zero results thus far. Is the amount of resources and time they are contributing to this cause really worth the incalculable chance they get a signal from an alien civilization? Having millions of PC's running at 100% doing pattern searching seems like a huge waste of energy. I'll run distributed clients myself like folding@home that actually have research results. Usually, only during the winter though (since electric heat is my only option anyway).

    Arecibo? I thought they were closing it? At least they recently lost around 75% of their fundings [slashdot.org].

    Me too. Last time I used it the Linux install involved way too many steps. It is packaged as a 'generic' Linux binary, and left up to the individual to tweak it to fit their particular system. I am quite happy to contribute spare cpu cycles to the project, but at the moment I don't have the spare sys-admin cycles required to setup, configure and babysit the software.

    If they want more people to install it, they need to do something like create a RPM installer and setup a yum repository. If the installation was as simple as 'yum install bonic' plus a simple Python configure script to set the project URL, then ReadHat could/would probably add it to Fedora. Which would mean that 1000's of people would see it listed in the install options, and some of them would probably give it a go.

    The other reason I left was the change in the way that stat were reported. When I started, their website showed a headline figure of number of CPU years in the last 24hrs. To me, seeing that figure increase as the project gained more users was a real incentive to add machines and contribute more to the project. It gave you the warm fuzzy feeling that we were all contributing to what was at the time one of the largest computing projects in the world.

    Now everything is listed as teams competing for 'credits', whatever they are. I didn't join to earn 'credits', I joined to participate in one of the largest collaborative computing projects in the world.

    Spoken like an ignorant minded bigot. As your GP said, Grow up. If everyone gives up one anything considered by others as pointless, nothing in this world would ever get done. While you consider this pointless, others do not. I would rather do both protein folding and SETI.

    I might also argue that protein folding is pointless since all you're doing is saving the life and therefore the DNA of an "inferior" person with a genetic disease. Why save them so they continue to pass on bad DNA? Why not let them die and keep track of their offspring so they don't procreate? As you've said, "It's pointless."

    Well, fortunately, not everyone thinks SETI is pointless, nor does everyone think protein folding is pointless. We would have achieved nothing if people didn't continue their "pointless" pursuits. Remember Gallileo? He said the Earth was round. At the time, others else believed it to be flat. His views were rather pointless too. Why pursue the facts when no one else found value. At the risk of his own life, Gallileo continued his "pointless" pursuit of convincing others that the world was round. Before you start to interject that we know the fact that the Earth is indeed round, I say to you that hindsight is 20/20.

    What may appear pointless to you now may lead to something more important than you can imagine. I say you need to grow up and accept the diverse views that everyone else has. There's room for all that research out there.

    No, he said the earth was not the center of the universe. Buy a history book. The ancient Greeks accurately measured the circumference of the earth about a millennia before that.

    Curing a disease is a short term goal. It means a few people might live because of someone finds out how to cure a disease. If they can afford the cure. For instance 10K people might be saved in the US a year if we could cure malignant melanoma. We could save the same number by preventing 20% of traffic accidents. CJD and vCJD kills so few people that each one makes the newpsaper. CG certainly affects more people, but these are more likely to be attacked from the genetic end. The approach to Alzheimer appears to be early detection and remediation, much like cancer. One wonders how many lives protein folding would actually save. Sure we would like to save lives, but we can probably save more lives by being more careful drivers, if saving lives were really a priority.

    OTOH, look at basic research. How many lives have been saved by the understanding of germs and need to sanitary living conditions and for medical practitioners to wash hands. Who would have predicted that the search for grand unification theory would lead to new and more precise treatments for cancer. I do not know if any useful information will result from the SETI work. What I do know is that dismissing any science as less important than any other science, solely based on the lack on near term practical application, shows a deep and profound lack of understanding of the nature of science. All systemic research is valid, good, and justified. I would also add that some of the least systematic and most haphazard and biased research is medical research.

    Seti's current data explosion is just a small step, once the Paul Allen (Co Founder Microsoft) new array of telescopes and research centres comes online, the data requiring processing will go up by several magnitudes (dont know how they are going to solve that one, maybe ask Larry Page and Sergey Brin if they could "borrow" the spare clock cycles from all the googleplex data centres), unless Paul has also provided a few millions for their own setiplex.

    Actually taking causality into account, haven't we already found them? Now we're just all falling toward the singularity that moment created in the future ::raises pinky to corner of mouth December 21, 2012 anyone?

    2. A negative result in science can be as important as a positive one. If we're the only intelligent life in this part of the galaxy, it might be crucial to know why.
    An anthropologist I spoke with a couple of months ago surmised that our current evolutionary adventure with intelligence is likely to demonstrate soon that it is a dead end. We're rapidly approaching a collision between the vestigial brain function requiring religion (apparently a necessary byproduct of the evolution of the intelligence attribute) and the ecological demands that require us to function rationally -- the antithesis of religion. He believes that, despite the best efforts of those who are aware of the problem, there will be no way to disempower the religion impulse in time to head of the catastrophe that is sure to result from its continued existence.

    If he's right, then the absence of evidence for other intelligent life is, so to speak, a no-brainer.

    That's not to say that it isn't worth striving to avert the catastrophe. After all, what do we have to lose! With that in mind, I've made it my life hobby to constantly look for and implement ways to subvert religion. Sadly, I can't report much success so far, but since I have nothing better to do I'll just keep trying anyway.
