  1. Re:23% revenue growth! on Amazon's Ambitious Bets Pile Up, and Its Losses Swell · · Score: 1

    This is a strange claim. Building a warehouse or any other infrastructure spending is an expense and will affect the profits, of course.

  2. asteroids? on How NASA Steers the Int'l Space Station Around Asteroids & Other Debris · · Score: 1

    What would an asteroid be doing in a near-Earth orbit?

  3. Re:correlation on USPS Discriminates Against 'Atheist' Merchandise · · Score: 1

    I am sure 9 vs 1 is a statistically significant difference.

    Whether the nature of branding affects the results remains unproven, as you say.

  4. Re:The best chess programs do not learn on DARPA Tackles Machine Learning · · Score: 2

    I never said that chess was machine learning.

    >And google search and translate isn't really learning, they're just statistical systems that given the best result based on the data they've gathered.

    And what exactly is your definition of learning?

  5. Re:This headline pops up every few years on DARPA Tackles Machine Learning · · Score: 1

    Machine learning and more broadly AI has had tremendous success recently. Google search is some sort of machine learning program. Pretty useful, no?

    I am not even talking about speech recognition, chess machines, auto-focus in your camera and so on.

    > You don't state why, but I'm guessing for intimidation/control purposes.

    Correct.

    > It is also in the FSB's interest to have people underestimate their powers so they will be incautious, using systems they believe are secure which the FSB can crack.

    I doubt it. Perhaps for NSA it is true, but most of FSB's power is based on raw force and intimidation, not any particular competence.

    And people who are really serious about security would use more secure systems in any case.

  7. caveat emptor on Russian FSB Can Reportedly Tap Skype Calls · · Score: 1

    This is a report in a newspaper citing unspecified sources. Moreover, it is in FSB's interest to have people believe that they are more capable/powerful then they really are. A large grain of salt is definitely in order.

    Clinton did not inhale. Now we know the reason.

  9. Re:Authors are lawyers on Are Plastic Bag Bans Making People Sick? · · Score: 1

    Not quite. The liquid will dry up pretty quickly and the chances of contamination will decrease dramatically. Certainly, the chances are higher than in a single use bag, but not that much higher. Moreover, what percentage of food poisoning is due to the in-bag contamination? I don't have any data but hard to imagine it being very large.

  10. Re:Authors are lawyers on Are Plastic Bag Bans Making People Sick? · · Score: 2

    Presumably, raw meat and such would be in a plastic bag or package within the reusable bag and whatever leaks would be a small amount.
    After that it needs to touch something that you eat raw without washing too much. It is not impossible, but does not seem too likely to cause problems. Certainly, the same thing can happen within a single use bag.

    The authors, on the other hand, are claiming huge percentage increases in food poisoning. Had to believe.

    Even if it is neither of those it can still be a win if it is non-toxic or easy to dispose of.

  13. Re:Like Obama? on Ask Slashdot: Will You Shop Local Like President Obama, Or Online? · · Score: 1

    In every modern society many services are provided by the government and cannot be provided by a private enterprise. Is it possible in principle -- how do I know? Is communism possible? There is not law of nature saying it is impossible, but there is no reason to think it is possible either.

    Are you saying that property tax is not paying for road building/maintenance?

  15. Re:Like Obama? on Ask Slashdot: Will You Shop Local Like President Obama, Or Online? · · Score: 1

    Well, property tax is also a tax. As far is the rest of the fees, I think only a very small portion of the road system is covered by that.

  16. Re:Like Obama? on Ask Slashdot: Will You Shop Local Like President Obama, Or Online? · · Score: 5, Insightful

    The point is that you cannot live in a modern society without using certain government services (at the federal, state or local levels) paid by taxes.
    To say that every service can be provided by a commercial enterprise is plainly ridiculous.

      There are certainly alternatives to the income tax, e.g., sales tax, property tax, etc. Each one of them has advantages and disadvantages.

    > I don't take services from the government.

    You don't use roads. That's impressive!

    >Aren't support vector machines provably more powerful than ANNs?

    In a sense yes. Both (non-linear) SVM's and Neural Nets are universal approximators. However, SVM's can be shown to converge to the ground truth given sufficiently many observations. No such result exists for neural networks. zz

    Well, real numbers are inherently very problematic from the computational point of view.

    > (b) using real numbers (real, not floating-point) would give a trans-Turing capability.

    Not sure what it means -- a Turing machine is not even capable of storing a single (arbitrary) real number.

  21. Re:from library to the cloud on Kurzweil: The Cloud Will Expand Human Brain Capacity · · Score: 1

    Both accuracy and permanence, unlike human memory.

  22. from library to the cloud on Kurzweil: The Cloud Will Expand Human Brain Capacity · · Score: 1

    This is by no means a new phenomenon. A library expands human brain capacity far beyond its natural limit.

    However a library has three basic limitations:
    1. It is not always available.
    2. The time to access any specific piece of information can be slow.
    3. The library is read-only

    The cloud has already overcome all three of these limitations to a large extent -- it is ubiquitous (available on cell phones and other portable devices), the search is far more efficient and the storage is possible (relatively easy).

    However the gap between the ease of storage/access/interface to human memory and the cloud is still quite large.
    The new technology will make this gap narrower and at some point in the future it may even disappear completely. Perhaps one would be able to bring up information just by thinking about the key concepts, words or images.

    The sun produces more energy in a millisecond than our civilization has used since the beginning of time.
    There is no scarcity of resources per se, just the scarcity of our ingenuity to devise methods to capture it.

    NASA is getting a significant amount of money and the payoff for much of it (manned space exploration, in particular) is questionable, while thousands of times more expensive than SETI.

    The frank answer is that we do not know how aliens may be talking to us (if at all).
