    The domains move at about 100 m/s. Light moves through an optical fiber at about 200,000,000 m/s. Assuming that your scheme was possible, it would represent a 2-million-fold increase in latency (at the physical layer). It would take a packet 12 hours to get from New York to Los Angeles, giving a round-trip time of about a day.

    Aside from the fact that it would be completely useless, it's also impossible. The internet is packet switched, not circuit based. There's almost never a complete, continuous "track" between a sender and a destination, although the sending to the loopback address is a significant exception.

    The big advantage is that there are only 26 letters used in English which can each be written in upper or lower case and print or script. Two days is ample time to learn how to read and write letters.

    There are tens of thousands of characters with varying stroke order and stroke placement. Each character may have many variant forms and there are many different styles of written characters. What percentage of those characters might someone conceivably memorize and learn to write correctly in two days? Is two days even enough time to learn how to hold a brush correctly?

    This comment is a bit ridiculous. Most Japanese people living in urban apartments don't have both a washing machine and a clothes dryer. The only available place is one's veranda. That's where everyone hangs their clothes. That's where she hung her clothes. It's definitely on the small side, but there are actually apartments with as little floor space as two tatami (3.64m x 1.82m), so sometimes just buying a dryer isn't an option.

  4. More Details. NOT a regular Streetview Photo... on Woman Sues Google Over Street View Shots of Her Underwear · · Score: 5, Informative

    Someone took a picture of her underwear and posted it on Google Streetview...

    Here's the original article.

    From the original article in the Mainichi Shinbun, "It seems that someone posted the picture of her underwear on the internet.[...] She said, "If it had been an exterior view of the apartment that's understandable, but that a photo of my underwear drying on the veranda should appear is strange no matter how you look at it."

    Again, this isn't just a case of something weird showing up on Streetview, according to the woman in question. Her paranoia is a little more understandable considering that she claims someone took a picture of her underwear and went to the trouble of posting it where she would likely find it. Being concerned about harassment or stalking isn't completely unreasonable.

    Some other details that were left out of the English article include that the woman in question is from Fukuoka City in Fukuoka, that she's in her twenties, that she was fired from the hospital were she was working, that she lived alone at the time of the incident, that she found the photo this Spring, that she filed suit in November in Fukuoka District Court and that opening arguments were heard on December 15th. As of December 15th, Google was hurrying to verify the facts of the case.

  5. Re:NK releases a statement like this regulary on North Korea Says War With South Would Go Nuclear · · Score: 1

    There was a large Korean population in Japan during the last years of the Japanese Empire. Many of them stayed in Japan after the conclusion of Pacific war and after the Korean War, the resident Koreans were allowed to register as citizens of Korea, but open affiliation with North Korea was made illegal. Despite this, approximately a quarter of resident Koreans have ties to pro-DPRK organizations, in particular Chongryon. Among other things, Chongryon operates pachinko parlors that generate revenue for the DPRK and it runs the 60 schools that teach DPRK ideology to Korean students in Japan. Chongryon's presence in Japan is effectively an extension of North Korea into a first world country, so its importance to the DPRK would be hard to overstate.

    There are probably more web developers among the approximately 150,000 pro-DPRK Koreans in Japan than there are North Koreans with any access to the internet, so it shouldn't be too surprising that such websites are hosted and maintained in Japan.

    Fuel isn't explosive and the capacitors only store at most enough energy for one round at a time, and, during a cycle of firing and charging with a fixed amount of power, will store less than half of that on average. Compare that to a traditional ship's magazine, which holds all the rounds that the ship might need in the period between being resupplied. On top of that, instead of storing high explosive warheads, the ship can store completely inert penetrators.

    Conventional wisdom has once again survived the onslaught of someone with just enough information to draw the wrong conclusion. You seem to have discovered that ordinary soap doesn't kill bacteria. Great, but that's not what soap is used for.

    Pathogens are typically transmitted in droplets of fluid or on the surface of small particles. (Soap won't help with a direct exchange of fluids, either with parasites or members of the same species.) Washing removes pathogens by removing the foreign matter in which they are present on the surface of the skin. Further, only the skin's outermost layer of dead, keratinized cells and oil is directly exposed to bacteria. Ordinary washing with ordinary soap removes a portion of these dead skin cells and sebum, taking a percentage of surface bacteria with it.

    You're "magically clean" after washing because there are less bacteria present. It's not necessary to kill that which can be easily removed.

  10. Re:You know... on Students Banned From Bringing Pencils To School · · Score: 1
    There are few ideas that are unqualifiedly bad. The fifth commandment actually says

    Honour thy father and thy mother: that thy days may be long upon the land which the LORD thy God giveth thee.

    A reason is specified for honoring one's parents. It's implied that doing so will result in long life. While it is possible to interpret this as God requiring action and threatening divine enforcement, it is also possible to see this text as an implication that long life is a natural result of honoring one's parents. Assuming that, God is merely exhorting this behavior for the benefit of the reader.

    Is it reasonable that honoring one's father and mother would result in a long life? In an often polygamous, highly patriarchal society with wealth concentrated among few older males, parental affection was a child's only practical hope for survival, let alone prosperity.

    There's no mention of abuse in the original, but considering the text in that context lends it a pleasantly fatalistic tone. Even if it's one's fate to suffer at the hands of one's parents, premature death is the only alternative to honoring them.

    Money and many other goods are traded in discrete quantities, so their utility functions are not concave, by definition. (Concavity is a property of the derivative.)

    Your so-called "concavity" is just a result of some assumptions about the behavior of the utility function as quantity increases without bound. Carefully review the derivation of the "law of diminishing returns" to see why. (I'm sick of making obvious counter-examples, but imagine a safe that requires three sticks of dynamite to blast open. Anything less than that has no value to the task at hand.)

    Elementary results typically make the many assumptions for clarity or in order to render calculations tractable. Don't bring them into a discussion unless you understand what assumptions were made and why.

    This is the arrogance that I mentioned. You're trying to tell me what $0.50 is worth to me.

    You can't possibly know the value of money to others. There are real world scenarios where your assumption doesn't hold. Suppose my life long goal is to own an ice cream parlor. I have enough money to pay my bills and exactly one extra dollar left at the end of the month. I would die before $12 per year was enough to start a business and I have enough money to meet my immediate needs, so a net change of $0.50 really is worthless to me. On the other hand, gambling allows me to have a miniscule, but real chance of getting the capital that I need.

    It's exactly these scenarios in which, depending on a person's values, needs and income, gambling can be rational.

    If you think that $0.01 is worth something to everyone everywhere, try handing out pennies and see how it goes. I await your report.

    The intentional abuse of legal authority by police officers, prosecutors and judges should be a capital crime. No other crime so greatly and directly injures the rights of the public as a whole while simultaneously destroying the ability of the people to defend those rights through legal recourse.

    The small risk of danger to fellow citizens and property damage caused by a single instance of speeding is routinely used to justify everything from excessive fines up to felony charges of reckless endangerment. In contrast, the irreparable damage inevitably done to both individual and public well-being, rights and liberty caused by a single act police or judicial corruption certainly merits more severe punishment of those responsible, but in practice is almost entirely unpunished.

    Though there are exceptions, even serial killers rarely have more than 15 victims. Over the course of a career, how many criminal cases does one judge try, for how many indictments is one prosecutor responsible, and how many arrests does one police officer make? In total, how many life-times of imprisonment, deprivation and suffering does each of those represent? Of course this is in addition to the actual loss of life due to beatings, cases of positional asphyxia, shootings and tasings administered by police and lethal injections administered by court order.

    Further, such acts demonstrate that the offender does not respect the rights of other citizens, which is the fundamental compromise upon which cooperative, mutually beneficial societies are constructed. Persistently ignoring and willfully violating others' rights is the essential core of antisocial personality disorder—a condition for which there is no treatment. Barring major advances in psychiatry, rehabilitation is simply impossible.

    There exists no graver crime. There exists no criminal with less hope of reintegration into society. If capital punishment is ever justifiable, it is justifiable in such cases.
