  1. Re:What about Google driverless car? on Software Bug Caused Qantas Airbus A330 To Nose-Dive · · Score: 1

    There are limits on the number of G's that are allowed and it will adjust the deflection of the elevator accordingly. Similarly, there are limits on the bank angles.

    The limits are mostly there to prevent unnecessary stresses on the airframe and make the aircraft last longer.

    The limits are reduced by flipping a switch or when sensor errors are detected, right down to direct flight mode which allows the pilot to do anything he wants (almost...really really stupid things like vertical dives are still prevented but in theory you could barrel roll one)

    The Airbus will also change the throttle to the engines without moving the throttle levers.

    I find that hard to believe. It simply doesn't work as a user interface to have the sticks not reflect the throttle (nb. this is true of any absolute input device)

    eg. Imagine the human puts the sticks at minimum and the machine puts the engines at 60%.

    If the human moves the sticks forward a notch then how should the engines respond? Should they go to 70% or should they drop down to 10%? Maybe they should they stay exactly as they are because the machine knows best?

    Electric motors are cheap, Airbus engineers aren't stupid, I'm going to demand a citation...

    It's a standard "defensive driver" technique to look behind you at a light in case you get rearended.

    What are you supposed to do in the one second warning you get? Hit the gas and speed into the middle of the intersection?

    (Assuming your car has enough power to get out of the way in a single second, which I doubt...)

    If you want to defend yourself against that then maybe you could sit with your arms folded and your head pressed against the headrest whenever you're stopped.

    What's wrong is that they live in hope that one day, somehow, they'll cross the line and be on that gravy train full of free money.

    In America it's called "The American Dream". It's why things like the outrage against wall street and the bankers is a few people in tents when it should really have far more pitchforks, lynchings and burning mansions.

  6. Re:No (First Post?) on Do Slashdotters Encrypt Their Email? · · Score: 1

    What we need is clients that do it all seamlessly in the background - the first few emails you send to anybody are used to do key exchange then after that it's encrypted. All the extra gobbledegook attached to the email is stripped off before you see it.

    Microsoft could easily have put it into Outlook by default and the world would have followed.

    I don't normally go in for conspiracy theories but in this case I think the reason that this isn't being done really is down to visits by the guys in the black SUVs.

  8. Re:LOL on Hard Drive Makers Slash Warranties · · Score: 1

    My experience is the opposite. I've had mostly WD drives for the last few years (a few Velociraptors and some other multi-terabyte ones for backups) and they're all fine.

    Drives that have died on me have been Samsung and Hitachi (quite a while ago...I haven't seen a hard drive fail for years).

    To me hard drives have always seemed to be a complete lottery. Avoiding a specific manufacturer is pointless. Look around: everybody posting here is avoiding a different manufacturer and all for the exact same reasons.

  9. Re:LOL on Hard Drive Makers Slash Warranties · · Score: 1

    All I see related to that is "Failure rates are known to be highly correlated with drive models, manufacturers and vintages [18]. Our results do not contradict this fact,"

    They also refuse to point the finger at anybody.

    When the study was published I remember reading some other stuff about the reason they didn't point the finger is because every manufacturer had ups and downs so calling drives from XXX 'unreliable' would be pointless because in the next six months they might get better while the 'most reliable' goes into a tailspin.

    Damned if I can find a link to that now though so you'll have to take my word for it. Or not...no skin off my nose.

  10. Re:LOL on Hard Drive Makers Slash Warranties · · Score: 4, Informative

    Yep. The Great Google Hard Disk Study revealed that no brand was "more reliable" than any other.

    Every single manufacturer had troublesome batches and/or models. No brand was immune to this.

    FWIW the single biggest factor they found which correlated to failure was heat. If your drive runs hot then expect trouble.

    Nope. Samsung used somebody's else's operating system (Android) and put it in a form factor which:
    a) Had been done before Apple did it

    Oh, hatchbacks don't count. You want an actual separate, trunk area of the car? I see...

    I don't think it's really more secure though. People who go around breaking into cars usually carry tools. If they want in they'll get in.

    Plus a window is much easier/cheaper to fix than a mangled trunk lid and broken trunk lock.

    Your country is weird....it's like you deliberately don't want people to buy small cars.

    Almost all cars over here are 'compact' or 'subcompact' but I can't think of one that doesn't have a trunk big enough to do the weekly shopping. Even a Smart Car trunk (one of the smallest I can think of) would hold half a dozen laptop bags.

    Guy in TFS says he doesn't have a trunk. I'd probably just take the backpack with me if I was that bothered.

    I've owned cars with no trunk but I never saw a car with a rear seat and a trunk too small for a laptop...

    If it was me I'd put a dummy laptop on the seat and put the real laptop on the floor with a black cloth over it.
