    Once you know the characters that the password consists of, the possible combinations are very limited. You can try every combination in a few seconds.

    But if you include a "delete" keystroke, you can include an arbitrarily large number of characters that don't appear in your password.

    They see the value in it, that's why they copy these items so quickly. They don't see the cost in it because there are no regularly enforced laws requiring them to pay.

  5. Street Safty on Student Killed Driving Solar Car · · Score: 0
    The vehicle's design is not really street-safe - this will be a problem as more efficient, lighter cars share the road with Hummers.

    This may be off-topic, but I think someone has to ask whether it's more in the public's interest to armour the fuel-efficient cars so they can withstand a Hummer, or make the Hummers more safe to get hit by.

    But you *are* moving. It just happens that your movement is cancelled out by the floor.

    It's not your velocity that causes motion sickness, it's the acceleration. The floor only "cancels" your relative velocity, as your frame of reference is moving with you; but not the acceleration, which you sense relative to a inertial frame of reference, which is essentially stationary.

  9. Re:Already done in practice... on Breeding Race Cars With Genetic Algorithms · · Score: 1
    This is already done in practice to optimize individual *parts* of a car.

    This has also been done in practice to optimize driving lines. There is an article in Auto-technology that shows that the classical paths are not the best unless you have a lot worse braking than acceleration.

  10. Re:what it shows ... on Breeding Race Cars With Genetic Algorithms · · Score: 1
    what it shows is that genetic algorithms are nice for parametric optimisation, but not for breakthrough innovation.

    This is true for every optimization method. If you allow the algorithm to "innovate" all you are doing is adding more dimensions to the parameter space.

    Roundup is not patented, IIRC

    Right, it was patented, but the patent expired a few years ago, so Monsanto had to drop the price of Roundup to compete with generics. They make their money off of technology fees.

    Their competition comes from Bayer Crop Science, whose "Liberty Link" system uses the proprietary (read: expensive) Liberty chemical (glufosinate).

    10% of the jobs are computer science jobs. These usually entail designing/optimizing algorithms or interfacing with "sciency" types like engineers(gasp), physicists and chemists.

    Good point, although I'd say that a good portion of that 10% are engineers, physicist and chemists, who teach themselves how to code a fuzzy controller by starting from scratch (and being forced to interface with (gasp) computer science people to get it to work right. )

    This statement is wrong several ways.

    I don't want to get too in depth about this, because there's so little reliable info to base assumptions on, but my understanding of the fact that he can "use an optical sensor to 'switch on' the 'stator' (electromagnet) for a fraction of each RPM" means that somehow he gets his advantage by pulsing the current to each winding once per cycle in sync with the motor speed (not a positive and negative pulse or sine wave). This would imply that he's using a DC source, not AC. In this case, the supply voltage is constant, so the average power is this voltage times the average current (RMS not required).

    But unless he actually publishes something, who really knows?

  17. Re:Quiet PCs? on Japanese Inventor's Motor Uses 80% Less Power · · Score: 1

    While there does seem to be problem with Minato's power calculations, I'd be surprised if this is the explanation. As long as he's using a constant voltage supply, the average input power can be calculated from the average current, which is what a standard multimeter will show if the current is fluctuating quickly and periodically. This is the power calculation that, I'd imagine, Minato is using to back his claims.

    While the average mainland Chinese is very poor, I think you're missing the fact that there are a lot of "nouveau riche" in China who want to buy the most expensive phone out there in order to impress their friends. Whenever you buy something in China, one of the first questions is, "How much did it cost?" and more expensive is better.
