  2. Re:At least it should be easy to do on Mandatory Brake-Override Proposed For All Cars · · Score: 2

    Yea! How am I supposed to burn up a set of tires in 20 seconds if I can't do a brakestand? If this rule goes in to effect, people will buy less tires which will mean less profits for tire manufacturers which will result in layoffs! This rule will cost jobs!

  3. Re:Brake override is built-in already ... on Mandatory Brake-Override Proposed For All Cars · · Score: 1

    In ideal situations, yes. However I was able to demonstrate that in both of my well-maintained cars there was a reasonable series of actions that could be taken in which I couldn't stop the car.

    Quick lesson: modern braking systems have a brake booster. This is a system that multiplies the force you apply to the brake pedal using vacuum generated by the engine. The vacuum comes from the air-intake manifold just past the throttle body, where at idle there's roughly a 22 inHg vacuum. Cars also have a vacuum reservoir so that the brake booster works even when the car isn't running.

    So, maybe you already see the problem. The vacuum reservoir is a limited (non-infinite) size. When the gas pedal is all the way down, the throttle plate is wide open and there's virtually no vacuum in the intake manifold. The brake booster still works because of the reservoir. However if you pump the brakes a few times, for instance a tentative "why am I accelerating" tap on the brakes or if you are pumping the brakes in a (pointless) effort to keep them from locking up or overheating, you can quickly "drain" the reservoir.

    I found on both my cars that the first 3 presses of the brake pedal had nearly full effect and would easily stop the car at full throttle. The fourth pump of the pedal was harder but it was still conceivable to stop the car. The fifth pump felt like there was a brick under the pedal and the car kept accelerating because I no longer had any assistance from the brake booster. I was quite literally trying to overcome the power of the engine with just some very inadequate hydraulic mechanical advantage.

    Please do not try this at home.

    It gets around that. The 10-attempt rule is implemented in the UI (unlike on Blackberries) and this "tool" boots the device into recovery mode and attempts passwords directly against the authentication module. It can attempt about 14 passwords per second.

  10. Re:Anything can carry nuclear warheads on DARPA Loses Contact With Hypersonic Glider · · Score: 1

    The problem with ICBMs, as far as I'm aware, is that they are Ballistic. This thing can presumably maneuver in the atmosphere and therefore hit smaller or moving targets. I'm not sure what the current state of ICBMs are, but if all the aiming is done in the boost phase then you're probably aiming at something the size of a city, while this thing could hit a city block or maybe a house. Disclaimer: The above is all speculation on my part.

    Apple users who, in my own experience, are overwhelmingly lefty.

    I don't get this. I've seen this comment frequently in relation to news about "The Daily", but I don't know where that impression comes from. Just about everyone I know owns at least one Apple product, and at least half of them would consider themselves right-leaning. Where has the "Apple users are Democrats/Liberals/lefties/whatever" come from? Would Apple's products be as successful if they only appealed to one political party? And how does one's political party influence their technology purchases and vice verse? Quick, someone find an undergrad who needs a thesis topic!

  18. Re:Power density or energy? on Penny-Sized Nuclear Batteries Developed · · Score: 1

    A power source that lasts forever is suddenly not very useful if it only delivers a few milliwatts

    I'm sorry you think so. I'd gladly take a power source that puts out a small trickle of energy; and I'd plug it into a Lithium Polymer battery. I use my flashlight for a few minutes per day if averaged out, so a few small cells like this could easily keep the flashlight topped off. Many devices that run on batteries have this intermittent power requirement. Then there are devices that only require a small amount of power. How much power does a smoke detector draw? Mine runs on a 9v for a year or more so what is that, 14 milliwatts? I can think of endless uses for something the size of a penny that puts out a few milliwatts.
