  2. Re:Not "really" P2P on MPAA Scores First P2P Jury Conviction · · Score: 2, Insightful

    Agreed, this is not the same as what all those other cases are, but you can be pretty sure that the MPAA is going to try and make it look like it to the general public. Unfortunately, I must agree with the conviction -- this really is clearly wrong (I am not commenting on the sentencing). It was being distributed before the movie was even showing in theaters! This clearly crosses the line of copyright law in both spirit and letter, unlike those other cases.

    Correct, assuming that the ice is floating in the water. In other words, the water level of water containing floating ice will not change if all that ice melts.

    The prediction of rising sea levels is based on the fact that a lot of ice is sitting on land. If the ice on lands melts and runs into the ocean, it will raise the sea level. Nothing is being removed from the ocean to compensate for the addition.

    But this study shows that they are centered near the correct value, even though the person doesn't know what that value is.

    This study shows not that multiple guesses are centered on the correct value, but that the average of those guesses are closer to the correct value than either guess alone (on average). The averaged guesses could still be far from the correct value, but they are merely less so than the individual guesses.

  6. Re:The moon does a lot of different things... on Mars Had an Ancient Impact Like Earth · · Score: 1

    Actually, the moon, by displacing a large portion of the mass, has prevented the earth from being as tidally locked to the sun as it should be.

    According to Wikipedia, the Moon has a mass 0.0123 times that of the Earth. Hardly "a large portion". I do grant that the Earth can not be locked to the Sun, since the tides created by the Moon are significantly larger than those created by the Sun.

    However, the Earth should tidally lock to the Moon, which is observed in the slowing of the Earth's rotation, as mentioned. This slowing force is related to the size of the tides and the orbiting period. As our day is significantly longer than either a month or a year, the orbiting period is negligible. The tides are not negligible, and since the tidal forces exerted by the Moon are larger than those of the Sun, the Moon is slowing us much more than the Sun would alone. In other words, the tidal friction between the Earth and the Moon is larger than the friction between the Sun and a combined Earth/Moon would be.

    One reason that "Mercury is tidally locked" (it isn't, it is in a 3:2 resonance) and "Venus almost is" is because they are far closer to the Sun, and the Sun's tidal forces are correspondingly larger. Another possibility is an impact on Earth increased its rotational speed.

    Tell me, what else do you think is incorrect?

    Alright, I'll bite. First, AC said "questionable", not "incorrect". I know I am skeptical of 3, 5, and 6. For 3 and 5, do you have references? I do not think they are incorrect, but rather that they seem like speculation. 6 seems implausible, for it seems to assume that (1) the Moon and the Earth can from the same pool of material, (2) that the volume of the Moon is large enough to affect the ratio of metals in the Earth, and (3) even granting (2), that the variation of the ratio of metals made it into the crust instead of staying distributed throughout the rest of the Earth.

  7. It may be inflated... on Only One Quarter of the Planet To Be Online By 2012 · · Score: 1
    These numbers are not all that reliable. It is often the case in developing countries the definition of "penetration" (word from TFA) is something like "someone in the village has it", or is within 5 miles. Electricity is often measured by the population that lives in cities and villages where there exists a customer.

    Case in point: my wife and I were in Laos visiting her relatives. We were going to a village, and I wanted to use our video camera there. I asked if there was electricity there, and was told "yes", so I did not bother charging the battery. When we got there, this is what ensued:

    Me: Can I plug this in here?
    Them: No, we do not have electricity.
    Me: Okay, who's house can we go to to plug this in?
    Them: No one's. No one has electricity.
    Me: But I thought you said there was electricity here!
    Them, pointing at the electricity lines coming into the village, which terminate at a big transformer box on a pole: We do have electricity here, it's just that no one has been able to pay to have it connected yet!

  13. Re:Um... What? on Fastest-Ever Flashgun Captures Image of Light Wave · · Score: 5, Informative

    Ok, first you have this coherent photon beam. This means that they are all traveling at the same direction. So how do you take a picture of THAT?

    In a different way that a standard photograph.

    You are bombarding the photon beam with photons,

    No, you aren't. That doesn't make sense.

    What they do is have the laser pulse travel through something they call a "chirped mirror". This packs the photos from the laser pulse into a smaller space. This then travels through a neon cloud, which then creates a flash of light. This flash of light is the "shortest-ever flash of light".

    To photograph this flash of light, they direct it into a second neon cloud, which ionizes atoms, releasing electrons. Those electrons are then recorded. Multiple flashes were required to produce enough electrons to build up the image shown in the article, so what you really have is an image of many flashes overlaid.

    I actually use Subversive, since it is an incubating Eclipse project. However, I may switch to Subclipse if Subversive keeps being sluggish. Also, I tend to be rather conservative about tools upgrades, which means that I often wait for a shaking out period before upgrading, and I certainly don't use release candidates. :-)

    There is an important piece that is going to keep me from being able to use it for a while:

    Before upgrading to 1.5.0, please take note of the following: * Due to various improvements made to the working copy library, the working copy format has changed. Using Subversion 1.5.0 on any working copy created by previous versions of Subversion will SILENTLY upgrade your working copy, which means that previous versions of Subversion will no longer be able to read it. I use multiple clients on my machine, and they all are going to need to be able to use 1.5 before any of them can.
  17. Re:Multi-layered security on How To Build a Quantum Eavesdropper · · Score: 1

    If the 'eavesdropper' can only make 'imperfect' copies then it seems to me using multiple levels of security would defeat the eavesdropper. For example private key encrypted data being tunneled over the quantum channel. Using this technique they would get a copy of imperfect encrypted data - which would be impossible to decrypt even if you had the private key . Remember that, even in the ordinary case, the receiver does not receive a perfect transmission, which implies that there must be some tolerance for error. An encrypted data stream would require error correction so the receiver could decrypt it. Therefore, for your idea to work, the level of error correction available must be such that the receiver can recover from errors, but the distortion from the imperfect copies makes error recovery impossible for the eavesdropper.

    As I did not read the paper, I do not know if this simply reduces to the original problem or not.
