Any race able to contact us or travel to get here is likely to be far more ethically and morally advanced that we are - it will, after all, have survived the equivalent of a nuclear age of technology without annihilating itself, and must therefore have a high degree of moral thinking.
This assumes however that morality and ethics have no "upper bound," that one can continue to advance up the moral ladder indefinatly. Where does this lead us however? There is no fundamental good and evil and moral structures simply grow out of the needs and necessities of society; they are there because they help us survive, help replicate and stengthen the meme. Evolution, and the universe in general, does not need morality to function. It seems to me that the logical conclusion of the moral progression is a realization of the inherent insignificance and ambiguity of our existance.
Perhaps this is why we have seen no ET life; its not technology that is lacking: billions of years have been available for a trans-galaxial society to form, rather it is a limit on meaning and reason./opinion?
"Turing is the man who created the concept of an "universal machine" which would perform various and diverse actions when given various sets of instructions. In other words, he laid out in the 1920s the foundations of software."
Actually the turing machine served as the basis of the first hardware, not software. Its really the theoretical basis for the entire computing model. I don't mean to be picky, but I have my Automata Theory final in 5 hours and I just spent all night studying for it..
this used to be true, but not anymore. Now that Bob has a 120GB hard drive he just downloads 50 led zepplin songs to his shared folder and doesn't listen to them.
I have had the pentium-M Thinkpad T-40 which has an larger battery option for about a year now. Runs for 8 hours with (5 with non-stop music/games), not cheap though.
what did you expect? be glad you got any credit at all, some good schools do not give credit at all; the test is too easy to be worth much college credit.
what about mobile computing? I think that the OS will be highly scalable, particularly because they are not willing to give up the growing (whats the percentage now?) laptop market, nor all of the lower end compuers.
uhm.. yea.. unless you think the people at Redmond are writing code that writes code that writes code, etc.. I don't see how the growth of the size of windows/office is going to be exponential.. There is no way that they code so fast they write anywhere NEAR a TB of code. sorry..
there may be a small amount of noise very near the space of focus, but similar things will happen with the ultrasound technique as well. Everywhere outside the space however, will have no signal (perhaps small amounts of noise) because the sum of the signals at this point will be random and will cancel (assuming a large number of signals).
not so. The point is that if a single beam gets muddied, thats fine. Only *one* location will have the focused signal from all of the different beams; the rest of the space will be nullified to nothing. The point is in the summation.
When is the beam a good thing?
You are right about the "take it out of box" part however..
you would be right to be skeptial. The idea is still in the research phase, however the results are extremely promising and powerful.. the best I can do for you is this: http://www.ncbi.nlm.nih.gov/entrez/query.fc gi?cmd= Search&db=PubMed&term=time%20reversal%20acoustics% 20AND%20hasabstract[text]%20AND%20English[Lang]
The reason that I know about it at all is because I know several people who are directly involved... give it about a year though =]
Unlike what most here probably believe, patents are not the problem. Microsoft will not be able to patent Linux out of existence.
they are not THE problem, they are one piece of the complete picture. Other pieces include (among other things) MS market share dominance, MS 'open' standards, MS lawyer crew. Combine all of these things together, and MS does have the ability and the intent to lock Linux out of market. Patents are an important part of this equation. IMO the article is right.
will dominate this market, because there is a new technique in acoustics that will eclipse the ultrasound method. Using something called time reversal, you can pinpoint the output of sound to a single location in 3 dimensional space, focusing around objects, people whatever; no beam, no drop off.
This focusing can be done with more than just sound waves however, and the first applications are in medicine, however, it does apply to sound as well.
The basic idea is that if you create a sound from some source location, and record all of the noise at another location, then play this noise signal backwards from the recorded location the sound will reappear in the one spot from which it was originally played. An analogy is that if you take a pool ball, put it right in front of a pocket, and then bounce it outwards really hard, letting it bounce against the walls multiple times, but noting the exact location of the last bounce of the ball, then if you reshot the ball at the exact spot where you last saw it bounce, it would go back in the whole.

you can't just multiply (S*P) and (s*L*I*C).
flip 2 coins, each has probability of landing on heads 1/2, yet its not always (2*(1/2)==1) the case that one lands on heads.
but then, I'm just being an ass, and this isn't at all important because the equaltion breaks down to:
x = chance of ET
where x is number between 0 and 1.

very nice =]
command and conquer on that thing would be a nightmare to play..
damn.. thats awesome; I had no idea this tied in with physical laws; but then we glossed over the proof in class..

you would have to pay for all of the jacks and tearing up the plane to wire it..
function calls? are you serious?
this guy is the father of automata theory..
you are right though, he should be on the list.
do you forward all of your email to gmail too.. like 2 copies?

I can burn my mp3s as many times as I want.. =]
becuase there is officially a limit on the number of times you can encode your files on to CD (used to be 10, lowered to 7).

remove ths space.

do you know if that offer is still available? (I just set up a blogger account...
