    "That's the thing about technology - it serves all masters."

    No, it doesn't. Every technology has a social bias, no technology is neutral. And the Internet is biased into making the life of the revolting people easier, and the life of the government harder.

    Why don't you want to reduce the conductive area (channel and poly sizes) while you increase the thicknes oxide layer? That would recude capacitance and leak rate at the same time, wouldn't it?

    But I guess it would be a bicth to manufacture... Thick and smal layers of oxide, those must be quite hard to corrode at the right shape.

    The paper was rejected because they didn't explain the how the machine is made nor showed the data they adquided from running it. In short, the paper had no information at all.

    They said they'll ship the machine soon. Ok, I'm not holding my breath, but they didn't ask for money, they made an ad.

    They say the machines produce cupper and zinc. Also, they hint about the nuclear reactions happening, and say they have evidence that those reactions are indeed happening. What they don't present is any kind of actual data (and somehow they say they didn't get gamma radiation, while their reactions imply they should).

    Now, fusion of heavy elements and fission of light elements are endothermic, as fission of heavy elements and fusion of light ones are endothermic. You can't make it oscilate, so the universe is safe.

    That's semantic game. Without government there can't be corporations, because what created that entity called "corportaion" is the Law. Without government the things that have the same characteristics of a corporation are called gerrilhas, or gangs.

    Sharepoint solves the wrong problem, but MS marketing makes people trink they want that problem solved. So we get at the worst possible situation, where we get a worse than useless software that is actualy well done (if you don't look to the backend), and your manager wants it. You can't tell him he shouldn't want it, and you can't tell him any competitor is better.

  15. Re:I'll be first to say WTF on Polynomial Time Code For 3-SAT Released, P==NP · · Score: 1

    As was already said, it is polynomial time, not linear. Now just proving that P=NP may not make an algorithm appear out of thin air, but it is quite likely that any proof of that will be done by creating such algorithm. And, by the way, that is the case here, the proposed proof is in the form of an algorithm.

  19. Re:Maybe 3-SAT isn't NP-complete on Polynomial Time Code For 3-SAT Released, P==NP · · Score: 1

    The one problem that all other are deduced from is SAT. 3-SAT is a friendlier version of it, that was proved to be NP-Complete by mapping SAT into it.

    But, yeah, most people try to map 3-SAT into their problems before trying with SAT. That is because 3-SAT is easier to think about, and somebody already proved it is NP-Complete.

    And, by the way, there are bare proofs about NP-Completeness of other problems, without reducing them. People don't like to use them because they are messier than simply mapping 3-SAT into your problem.

  20. Re:What, exactly, is 3-SAT? on Polynomial Time Code For 3-SAT Released, P==NP · · Score: 3, Insightful

    A small correction. The NP-Complete problem is "Is there any input for what it evaluates to true?". NP problems are exclusively yes/no ones.

    Now, if you solve the SAT problem, you can derive an algorithm for calculating the solution space. It will probably take exponential time. You can also derive an algorithm for finding an input that evaluates to true in polynomial time.
