SETI to Upgrade Software, Telescope 246
Professor_Quail writes "Space.com reports that SETI@home is planning to transfer it's operations from Arecibo to another telescope in Australia, where they say lies an increased chance of finding extra-terrestrials. The Australian telescope is more powerful, with a wider view of the sky; scientists are betting that this new telescope will also help find signs of 'shriveling' black holes."

I'm told, admittedly by The Learning Channel, et al, that "each galaxy has a black hole in the center." That makes me wonder...it's probably there for a reason. Yeah, I know- great place to dump the trash....but maybe it's something more. I'd like to think that perhaps they might be connected....and if we could survive the massive gravity, that would be a way around the whole speed-of-light thing, or at least shorten it a lot.
I'll bet that won't make any sense at all in the morning. I'm turning in. Night all!

to be honest i think seti@home will never be used for anything more then crack codes and make calculations. (which is what it partly is being used for anyways)

And of course anything we find will be of such level of intelligence output transmission as is required to be picked up by our receivers. Meaning our receivers are limited as to what type of intelligent life transmission we can detect.
Certainly in all that is really possible, beyond our limited science, there is a greater possibility that intelligent life elsewhere has developed their technology under different conditions and perspectives/perceptions and as such has developed technology differing enough to be somewhat incompatable and therefor undetectable to our receivers.
Then there is the possibility that Intelligent ET life is and has been in our presence for ages, but doesn't want to be so widely known. Consider our own abilities as comparied to another animal and how such other animal cannot comprehend much that we do. Likewise, it is possible that there is such life that we too have such a level of difficulty in comprehending.
What might be a good example of our limitations is that we have yet to openly, as a world population, recognize the limitations and inherent constraints in technology and social advancement that wrongful abstraction manipulation (deception) causes. And as such we as a population whole, do not understand the full power and potential of using such techniques in deception, which are easy to apply and safe from proof, that we can recognize such being applied.
But if we are not alone, that there is a more intelligent life form present, I suspect that they would understand such powers of deception and use it to keep hidden.
In short: Communication between intelligent life forms is a two way process. Anyone got proof they want to communicate with us?
Optimizations (Score:3, Insightful)
"KLAT2's 80/64-bit double-precision performance is around 22.8 GFLOPS, a very respectable number. Then again, using 3DNow!, KLAT2's single-precision ScaLAPACK performance zips to over 64 GFLOPS"
Optimize clients for different architectures. MMX, 3Dnow!, SSE, SSE2, Altivec, Hyper threading, x86-64 etc.
Might be nice to jump from 50 Tflops/s to 150/s just by using processor specific instructions.
Since the client will be open source, users may try it anyway but perhaps SETI could offer some kind of contest to insure the code gets audited properly.
For programmers out there, imagine placing "Optimized code for the largest distributed computing project in the world, resulting in a threefold increase in performance" in your resume.
Being personally responsible for adding 100 Tflop/s to seti@home beats the hell out of running clients on a few idle machines.

I say all this scanning of the skies could be put to equal if not greater use by developing a distributed computing client that scans the skies for possible asteroids that may pose a threat.

WARNING: Upgrades that download automatically without any user intervention? Have they gone "BOINCers?" This is a very bad idea that will create an enormous security hole. My prediction is that most businesses that currently allow seti@home will ban the new BOINC system.

Statistics: The Second Great Evil (Score:2, Insightful)
When anyone starts talking statistics when referencing outer space, I just have to cringe. So, let me get this straight, just so I understand your argument.
1) aliens who use radio waves must be technologically advanced.
2) Technologically advanced aliens would expand to other planets (why? what if they cannot handle weightlessness, what if they don't WANT to?)
3) Said expansion would use relativistic speeds at all times to expand
ergo: We would not recieve signals much before we recieved aliens.
Now, let's look at a simple argument against your _Very_ loose logic.
1) Space is three dimensional. Even assuming your "expansion" theory is correct, you must assume either (a) the species multiplies as fast as they expand radially outward (so that the population density is large enough that they will run into us eventually, as their expansion reaches us.
or (b) they are targeting us as a direction to move towards. Personally, I don't find any plausibility to either of these arguments.
2) You assume that since it only took us several thousand years to get where we are, there would HAVE to be species that evolved before us. There is no proof, anecdotal or otherwise that we, as a species are either late or early comers to the scene. I am resonably sure that to be able to withstand the change needed to create technology, some form of advanced, multi-cellular organism would be required. This requires a long process of evolution, assuming you believe in such.
There are other problems, I won't go into them now....

Perrin5, I think you're missing part of his point. He projects that a healthy spacefaring race would colonize the galaxy in a million years. This part is arguable, but if humans eventually do this that seems to me to be a reasonable estimate of the length of time required.
As to your specifics:
1a. I find completely plausable. Radial expansion at a constant rate is a much shallower growth curve than an exponential! Suppose that humans radically slow our population growth, so much so that the population requires 100 years to double itself. Multiplying our current population by 100 billion (very roughly the number of stars in the galaxy) would take less than 4000 years. I expect that humans (and Alien species X) would not have a problem of not enough population growth. This also could be the expected motive for Alien species X to expand.
2. You completely miss the point, he assumed no such thing. He merely pointed out that given a rough million year timeframe to encompass the galaxy, an unknown civilization would have to be very very recent by galactic time standards for them not to already be here. If you believe his expansion timescale, the first species to achieve spacefaring colonization would be overwhelmingly likely take over the whole galaxy; it would require a huge coincidence for two species to start expanding at times close enough to overlap, given how quickly the takeover is expected to take on a galactic timescale.
