  3. Re:Worthless security lightened on TSA To Allow Laptops In Approved Bags · · Score: 1

    Before 911 and massive official paranoia, Heathrow worked like this: while your baggage is in the scanner, you go through the detector, get a pat-down if it beeps, and keep going without one if it doesn't.

    That was before everyone went crazy. On one flight I was on, everyone went through the detector, and everyone got a pat down. Whether the machine beeped or not made no difference to anything. I still wonder why the machines were powered on.

  5. Re:HP on Laptops With Certain NVidia Chips Failing · · Score: 1

    My dv9000-series laptop with a 8600m GS (that's a G84M core) failed a few months ago, with the screen regularly not showing anything on boot up, or either loosing the screen or getting kernel panics in the nvidia driver after a few minutes running. Clearly a failed GPU. HP UK was very good about it, picking up and returning it by courier (with a new motherboard) within a week of me phoning them. I've heard nothing about extending the warranty, however, which comes to an end in a few days.

    Which country are you in, and how did you get the warranty extended?

  6. Re:A few points to consider on Nukes Not the Best Way To Stop Asteroids, Says Apollo Astronaut · · Score: 1
    You assume an asteroid has to hit the surface to do serious damage.
    .

    I might also point that a very large blast is not much of a threat if it is too far above the surface of the earth.

    I presume you refer to the blast of a disintegrating asteroid (the nuclear stuff would all happen thousands of kilometres away).

    The atmosphere is thin. There is no "far above the surface". Imagine the Tunguska Event occurring over a populated area. The most popular theory has a 15Mt explosion (approximately Hiroshima) happening 5-10 kilometres up, caused by something as small as 50 metres across.

    The object responsible for the Cretaceous-Tertiary event, which is everyone's favourite worst-case mass-extinction nasty, was most likely about 10 kilometres across, so (plenty of) city-flattening 50-metre fragments seem pretty believable.

    You do not really want to blow the asteroid to bits if you can possibly avoid doing so. I should also point out that many asteroids are not hard enough to embed a missile in, and many will need to be pushed really quite gently if they are not to break up.

    So the control column moves the control surfaces by pulling on strings just like a 1920s aircraft?

    All large modern aircraft, including civilian airliners, are under a varying amount of computer control. For example, no modern airliner would require that the pilot on a transatlantic flight continually manually adjusts the heading for several hours to compensate for the wind. May aircraft can be landed automatically, and indeed some cannot be landed by the pilots in extremely low-visibility conditions. In many Airbus aircraft, it is not possible to control some aspects of the aircraft manually; for example, in certain aircraft the autothrottle is always on.

    The current level of computer control is made safe by very careful testing and by much redundancy. There are usually at least two fallback systems for each component, and these are often designed by different groups to reduce the probability of all failing for the same reason. Wikipedia's article on Fly-by-wire systems is rather interesting.

    From the Wiki page:

    In 1984, the Airbus A320 was the first airliner with digital fly-by-wire controls.

    You're out of date by almost a quarter of a century. Please don't call people "idiot".

    We still don't have computers that don't crash frequently, or have various other software problems. ATMs with blue screens are a common occurrence. One computer glitch in a robocar could cause many fatalities.

    No, you mean you don't see computers that don't crash frequently, because people prefer cutting-edge to stable, for the machines they actually have to deal with. How the hell do you think air travel works without thousands of fatalities a day?

  16. Re:um, radiation on Full Body Scanners Installed In 10 US Airports · · Score: 2, Interesting

    Another student of physics here. You can make pretty much any frequency of radiation you like by moving electrons at that frequency. The difficult part tends to be how to move them about that fast. :-)

    Efficient emission and detection of Submillimeter radiation has not been practical for very long, which may be why you haven't heard of it. It's most often refered to as Terahertz Radiation.

    If you want stories of people being purposefully mislead, they outright lie about these things in Heathrow airport, London.
    The signs tell people that the machine uses a "very low dose of x-ray radiation". I was picked for a random security check, and given the choice of the scanner or a manual search. The manual thing sounded kind of scary, so I went for the scanner, in the full knowledge that it involves someone looking at my naked body.

    Now, because it sounds a bit frightening and was very new then, they were obviously instructed to reassure people about it, so when I insisted on seeing the images, they let me (they showed me the shot from behind, presumably in the hope i wouldn't realise they'd obviously looked at my cock). It was very obviously a Terrahertz-band scanner, but the staff and all the signs stated it was an x-ray machine, because everyone is used to those.

    Guess not everyone is a physics student who knows that X-rays are more dangerous than T-rays! I wouldn't have gone in the machine if I hadn't been totally sure that the ionising radiation was a lie.
