  1. Re:Seamless Math Next? on Detecting Faked Photographs Gets Easier · · Score: 4, Interesting
    One could read into these lines that the ability to fake photographs was great until anyone could do it. Now that we know how easy it is to fake photographs, we no longer implicitly trust messages...but we will trust mathematically authenticated fake photographs because math is infallable.
    Or you could read into them that when it was rare and difficult to fake photographys, most of the photographs you saw were genuine, so you could place a decent amount of trust in what you were seeing. Now that faking photos is easy and commonplace, you can no longer place much trust in photos. With mathematically verified photos, you can place more (though not complete) trust back in the photo. It isn't foolproof but the level of assurance is significantly higher.



    Or you could realize there's inherent error in any statistical method, and that with a little bitof foresight, this error could be expoited to provide false results. The best detector of falsified photography is still a well-trained human eye. The key to knowing whether or not to trust images is to train your eye.

    just nitpicking:
    Unfortunately, due to the very construction, the closer two hammers were, the easier it was to jam the typewriter if you pressed both at the same time. E.g., if you pressed Q and W at the same time, the machine would pretty much always jam, whereas pressing Q and P at the same time would almost never jam.
    Since every key must strike the same location for proper text alignment, simultaneously pressing two keys will guarantee a jam. However, it is easy to see how when closely timed, a larger distance between levers does reduce the likelihood of jamming.

    why not just say 'a is 36'? :p

    nah, really, there are ways to do it that aren't very clunky. Perhaps "a is the sum of three and six, four times" or "a is four times the quantity three plus six" would work. Both convey the appropriate meaning concisely and leave little room for misunderstanding.

    On the same note, I've read that the classical Greek mathematicians used no shorthand in their works. That's really sobering when you consider how much of our understanding of algebra and geometry can be traced back to them.

    Personally, the thoughts in my mind as I read resemble mathematical shorthand do not resemble the shorthand. It is simply too abstract for me to internally digest without translation into meaningful ideas. (incidentally, I've recently been introduced to group theory and while it is clearly useful in the context which its been introduced -- QM in a chem class -- I find myself really unnerved by the seemingly arbitrary shorthand on which it is established)

    yeah, but the EZ bake bulb's filament burns at something like 5000-6000 Kelvins to put out enough infrared to do its cooking. The pentiums, by comparison, will run around 325-340 K, and the wavelengths emitted will be far too long to be useful for cooking. By Wien's Law, the peak wavelength would be around 8.5 micrometers whereas with tungsten filament bulb. With the nature of the falloff toward the blue side of the peak radiation in the Stefan-Boltzman distribution at a given temperature, almost all of the energy would be wasted at wavelengths too long to really heat most substances. You would need good thermal contact to do it at those temperatures.

  9. Re:I hate beer snobs on Keeping Your Keg Cool Sans Ice · · Score: 1

    > a lot of microbrews kick serious ass.

    Indeed. Stone Brewery's Old Guardian, Arrogarnt Bastard, and Double Bastard Ales are excellent. Anything from Pete's Wicked is good (well, I've only had their brown ale but people say their strawberry blonde is just as good), and Old Rasputin, IMHO, even beats Guinness Draught. The annual belgian style ales from Lagunitas can make any summer after more blissful. And I'll almost never turn down anything brewed by Firestone, although I don't know if they're considered a microbrew.

    btw, anyone else find it really funny that the 'I hate beer snobs" poster user so many acronyms? Clearly, the implication is a poor taste in beer rather than any anti-snobbery opinions because the lack of accessibilty in posts over-using acronyms is itself quite snobbish.

    actually, as a Californian, I'll tell you exactly what happened with the power comapnies: The back-end suppliers were de-regulated without removing the rate caps from the market-end. The result was definately NOT privatized electricity, and absolutely doomed to fail whether it was constructed in a communist or capitalist environment. The idea of having every company owned and run by the government (pure communism) is just as bad as the idea that government should have no power to break monopolies (pure laissez faire capitalism). In both cases, power accumulates to an unacceptable degree within the hands of too few people. Examples: Soviet Russia. Sorry to break the news, but it fell. Another example: Debeers. Diamonds are practically worthless. The only reason they get such a high asking price is that one company controls over 90% of the world's supply and they can keep it lower than demand. It's the same game OPEC plays.

    Progressivism is definately the wrong term for a theory that demands cradle-to-grave governmental hand-holding. It's not forward thinking. It's simply restoring the monarchial powers of state without simply giving the throne to a single family. It is just as conservative wanting the government to step aside and allow the establishment of a corporate fiefdom.

    I don't think you understand what I meant. Tactically speaking, the soldier is in a neutral stance. metaphorically, it's like having the fire selector set to safety. his finger is out of the trigger guard and he is not exhibiting any sort of agressiveness. I think the best way to say it is that he is carrying his rifle. The rifle may be pointing but he is not pointing it. By comparison, the agent in the Elian photo had his weapon shouldered and was indeed pointing it (although even in that case, his pointed finger outside the trigger guard indicated quite a safe position, as well.)
