    You also have to be able to determine the position of the ball at all times, to determine the "spot" when it's determined by "forward progress", or if the ball crossed the goal line and was then moved back.

  2. Why wall warts on New Energy Efficiency Rules For TVs Sold In California · · Score: 1

    There are several reasons that manufacturers like to use wall warts

    • Using a wall wart makes the powered device smaller.
    • Using a wall wart reduces power dissipation in the powered device.
    • Wall warts are usually provided by a third party, saving engineering cost and time.
    • By using the wall wart, no UL approval is needed for the powered device (usually). The burden for UL approval falls on the wall wart manufacturer, since that's where the risk for fire and shock is located.

    I don't like having to pay for the electricity that keeps a wall wart warm to the touch. The problem is that there are significant advantages for a manufacturer to use a wall wart.

  3. Re:Peoples Republic? on New Energy Efficiency Rules For TVs Sold In California · · Score: 1

    Typically for slashdot, a justice-based approach has not occurred to you.

    If someone breaks a window, you don't force him not to break windows anymore or increase taxes so that the government can fix the window. The perpetrator should (be forced to) pay for replacing the window and for all collateral damage.

    Likewise, the PROVABLE damages (that includes the statistical probability of disease, lower quality of life) caused by a polluting power plant should be paid to those who suffer the damages. Naturally, the costs get passed on to the customers, who complain and look for better power sources. Competition yields a tradeoff between purity and expense, and is in some sense an optimum result.

    Compared to the open-loop application of government force, the result of a justice-based approach seems similar on the surface, but the difference in the details is crucial. Everyone gets what they deserve and pays for the damage they do, even if the damage is done indirectly.

    Thanks for the efficient motor citation. The motor is (thermally?) limited to 1.8 kW (2.4 hp) continuous, 5.4 kW (7.2 hp) for 72 seconds. It weighs 6 kg, or 14.5 kg including wheel and tire. It's very expensive (AU$12000), probably due to low production volume. Multiply numbers by ten for something that might be usable in a production car.

    Atheism brings to the table the lack of a particular widespead class of flaws called religion. It is a lack of a certain variety of irrationality.

    Just as a lack of viruses does not cause health, a lack of religion does not cause rationality. Atheism removes just one impediment to a good life.

    "Ability" is not something that can be acquired, it is something that is inherent. Hands give a person the ability to grab things in a way that no person without hands has the ability to do.

    "Gifted" is a very poor word because it carries with it a lot of baggage. It implies a giver, a god or parent. It implies an obligation to the giver, a lifetime servitude that can never be repaid.

    "Ability" is the word used for someone with a promising future. "Gifted" is the word for a curiosity, a person with a burden, a person that can't make it without his "gift".

    This may be a charitable action by Google. The DOJ has a finite budget, and by helping the DOJ to waste money, Google has weakened the ability of the DOJ to attack other innocent organizations.

  15. Nightfall on New Asimov Movies Coming · · Score: 1

    If the film Nightfalls were based on the story, they couldn't help but be lame. The author had a strong premise (religeon destroying civilization) and he undercut it near the end, refusing let the blame stay where it belonged. Cowardly, I suspect.

    Arthur Clarke had a similar idea (The Star) but developed it in a completely different manner, not really conducive to film. Read it to learn the true meaning of Christmas.

    Fredric Brown had the best treatment of the idea (Answer) and carried it through in a single page. Astonishingly, this could be successfully developed into a good movie.

    Flicker sensitivity varies with brightness level. Eyes integrate at lower light levels, so flicker becomes less noticeable. If flicker bothers you and you can't change the frame rate, you may be able to help yourself by darkening the room and/or the image.

    1000 lines on a 50" screen (30" high) at 8 feet (96 inches) is close to a minute of arc per line. The eye can resolve about 0.3 arc-minute on a static screen under good conditions.

    At 15 feet 1000 lines is about 0.5 arc-minute, not far from the limit of the eye. It should be visibly better than the 480 lines of SD, but only to a careful viewer with good vision.

    Actual analog broadcast NTSC only provides about 300+ pixels of horizontal resolution. At 15 feet (180 inches) those 300 pixels on the 40" wide screen are 2.5 arc-seconds. This horizontal resolution is clearly inferior on any scene with sharp vertical edges.

  20. Re:Supplements on How to Deal With an Aging Brain? · · Score: 1

    Most negative studies of vitamins are flawed in significant ways. For instance, studies showing that more than 400 IU of vitamin E is harmful are using only alpha tocopherol. It's been established for more than ten years that if gamma tocopherol is missing from the supplement, more than 400 IU of alpha tocopherol depletes the body's gamma tocopherol, and that is harmful.

    The idea that an uncontrolled diet provides optimum nutrition is laughable. Intelligent supplementation improves the odds that you're closer to optimum.

  25. Re:Hmmmm on 3 Firms Confess To Fixing LCD Prices, Agree To Pay $585M Fine · · Score: 1

    My tax money buys me civilization.

    This is patently false. For counterexamples, I cite every government on earth.

    A proper government provides a framework in which a civilization can be built. It defines behavior incompatible with civilization (we call these definitions laws) and provides some degree of protection against uncivilized behavior.

    Theft is an uncivilized behavior, and the only distinction between theft and taxation is that the government performs the latter. To maximize civilization, theft needs to be minimized. To do that, taxes must be used to discourage things as bad as or worse than theft, and NO MORE.

    Alas, all governments steal much more than is needed, and use the excess to perform all sorts of marginal or destructive activity. In the United States, more than 85% of the federal budget is destructive toward civilization.
