Is Distributed Computing Being Distributed Badly?
Carl Bialik from WSJ writes "Distributed computing could help researchers studying climate change or Alzheimer's, but SETI@home's search for extra-terrestrial intelligence continues to dominate. Wall Street Journal columnist Lee Gomes says that's a big waste, especially because SETI doesn't seem likely to yield results: 'This continued fascination with living-room SETI comes as professional setiologists concede that early assumptions about the search for intelligent life -- notably those popularized by astronomer Carl Sagan -- have proven naively optimistic. For instance, it's now conceded there is little chance of detecting the "leaking" transmissions of another planet -- its version of "I Love Lucy" broadcasts. Those signals are too weak to stand out from the universe's background noise.' Gomes also traces the origins of SETI@home to Berkeley computer scientist David P. Anderson, and explains that users stuck with the ET search rather than medical investigations in part because of nationalistic competition. Yet Anderson no longer runs SETI@home. 'Instead, he donates his spare computer power to a global warming project. But he doesn't presume to tell others what they ought to be doing with their CPU cycles.'"
of course the WSJ would much rather you where crunching numbers for their drugs companies under the guise of "fighting cancer" or "protein folding" so your results can be turned into their profit (you didnt think that cure/treatment would be free like your CPU did you?)
searching for ET is not profitable so it must be bad
"Instead, he donates his spare computer power to a global warming project"
Does this attempt to determine how much global warming is being caused by donating CPU cycles.
I currently work for a pharmaceutical company, and in a visit to a research lab I learned just how much computing power they throw at these problems. They do have supercomputers, intranet clusters, etc. to try to solve these problems. They are so incredibly complex, however, that those are not enough.

While I agree with the principle here, don't forget that with legalized banking fraud ("fractional reserve banking") they don't have to actually print more money to increase the effective amount of currency; they can simply lower the mandantory reserve ratio. Should the LBF system ever fail, the FDIC will be forced to step in and print massive amounts of paper currency to back all those accounts.
Conversely, credit contraction (higher interest rate & reserve ratio) has a deflationary effect equivalent to that of taking paper currency out of circulation. While I do believe that the long-term trend is toward inflation, indications are that we may be approaching a credit contraction phase, and thus short-term deflation. It may or may not manage to balance out the overall inflationary trend, but it's something to watch for none the less.

Radio SETI is really a waste of time. Optical SETI is the logical choice because;
1) Visible light-emitting devices are smaller and lighter than microwave or radio-emitting devices.
2) Visible light-emitting devices produce higher bandwidths and can consequently send information much faster.
3) Interference from natural sources of microwaves is more common than from visible sources.
4) Naturally occurring nanosecond pulses of light are mostly likely nonexistent, although there are all kinds of radio signals that could be similar to intentional SETI transmissions. Thus Optical SETI does not require grid computing to find signals.
5) Exact frequencies of light are not required, as nanosecond unfiltered light pulses would still outshine the planet's star by over 30 times.
Optical SETI detection out to 100 light-years is doable today, with a bit more work optical SETI out to 1,000 light-years is possible.
