500-fold Increase in Data Flow from SETI Telescope

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."

    Protein Folding should take precedence over pointless searches for noise-in-patterns.

      So what are you doing here, wasting your important CPU cycles?

      Protein folding is important, however discovery of ETI ranks up somewhere along with; fire, wheel, tools, calculus.

      Find a protein, you change many lives for the better.

      Find ET, and you change the course of the human race forever.

      I will choose what to do with my extra CPU cycles myself, thank you very much. To me, ET is more interesting.

      (Yes, I should know, it was my computer that discovered the candidate object for SETI@home back in 2004. Got on TV and weekly reader for that. What have YOU done with your spare CPU cycles?)

      My only regret is BOINIC runs so crappy and is so hard to manage (come on, install a program that crashes upon resume, gotta dig out the right profile, gotta figure out how to sign up for projects = fail).

  2. are the cycles really "spare" by atarione · · Score: 4, Insightful

    i was kinda interested in this at one point then when I installed SETI@home i realized that it made my proc max out 24x7 and shoot up to it's load temps (obviously) and of course use more electricity. i decided that I wasn't willing to stress my equipment or pay for the electricity to run this type of software ( I do of course realize you can set the amount of cpu it uses.. but still) I think that all these distributed projects kinda try to gloss over the fact that it isn't free to participate ... and given the $100+ a barrel oil at the moment people that chose to participate should probably be made more aware of what the costs and wear and tear impacts really are.

    People should have a free choice about the causes they donate to. If you made everyone pick Protein Folding, it would be akin to just another tax.

    Just because you think you know what people should do, doesn't mean you do.

  4. oh I dunno by Quadraginta · · Score: 5, Insightful

    There's a logic error here, I think. By this logic, we should do nothing except the very highest priority thing in our life, and society should pour all of its resources into the very most important priority. For example, we should all live in a thatched hut, eat weeds and grubs, wear the untanned raw skins of animals (or just go naked), and slave 18 hours a day so all our labor and energy can go into....whatever the single highest social priority is...curing cancer, fighting war 'n' injustice, whatever.

    Which is silly. The goal of life is maximize overall satisfaction, not accomplish one single highest goal. It's important to rank your priorities, of course, both as an individual and as a society. But the notion that because A is "more important" than B implies ipso facto that A should get all the resources and B should get none is maximally silly.

    Indeed, it's kind of OCD obsessive to always be focussed on pursuing the Top Goal, the kind of thing that when we see people doing it in practise -- giving up everything, including enough sleep and good nutrition, to, say, play World of Warcraft and become the biggest baddest player -- we conclude they need to do some growing up.

  5. How wasteful is SETI? by Darth_brooks · · Score: 4, Insightful

    Fine, I'm burning cycles running a project that may (heck, when it comes to SETI, probably) won't see any tangible results.

    But how is contributing to a project that was the basis for mainstreamed distributed computing any more wasteful than blowing 9 hours a night on WoW? I'd love to see a breakdown of the increased energy usage from a high-end CPU and a good video card vs. a PC that's on anyway and running BOINC when it's idle.

    Screaming "carbon footprint!!" about something as trivial as BOINC is the real waste. Here, I've swapped 80% of the lights in my house for CFL's, and I burned 10 bucks worth of electricity last month (with an electric heater and 4x computers in the house no less!) does make me green enough to spare some processor cycles now?

  7. What seems to be overlooked about SETI by doggod · · Score: 3, Insightful

    I almost never see anyone take note of what I deem to be the only to-date achievement of SETI -- defining a larger and larger region of space where it is known that there are no radio signals indicating intelligent life. Everyone seems to be focused on the expectation -- seemingly bordering on the religious -- that ET life will be found because it just HAS to be there.

    I would note that there is no fundamental reason for this axiomatic proposition, and it makes much more sense simply go with the data rather than stubbornly cling to a belief for which there is so far not a shred of evidence -- much as the creationists do with regard to geology and archaelogy, I would note.

    Maybe sometimes some evidence will appear for ET life. That will be interesting, if so. In the meantime, we have a rapidly growing contrarian body of evidence, so we should accept as our tentative conclusion that we are, in fact, the only life in the universe.
