  1. Re:Stuff happens; learn from it. on NASA Finds Critical Assembly Fault in Shuttle · · Score: 1

    Things will go wrong. Learning how to cope when the evil wind blows is critical. In this case, we now know that the thing can be flown with one actuator in upside down. If the bottom one malfs, swap it out in orbit with the top one, and you still might get home.

    Um, not likely in orbit. From the article:

    Discovery flew safely 30 times with the defective actuator since its first launch August 30, 1984, and no one suspected a problem until the actuator was taken apart to check for corrosion.

    We're talking about an assembly that has to be taken apart to get to the offending part. That assembly is part of another assembly, and so on... most likely, getting to it requires a large winch to connect to the rudder itself as you unbolt it from the vertical stabilizer, and disassembly of several massive, yet intricate parts.

    On every spacewalk I've seen, just turning a bolt requires intense physical and mental effort. Not likely to replace this particular part in space.

    Besides, note when the fault will present itself:

    When a shuttle returns to Earth, the rudder brakes the craft to a speed that is safe for landing. [...] the faulty actuator could not have handled the most extreme forces during landing if it had been in the bottom position.

    By the time the thing fails, you're already a flying brick that can do very little but fall with style.

    You're main point is well taken -- we're learning as we go along. Just nit picking about the details, that's all.

    Prevention? Against groups for whom "getting caught" is a negative, sure. But last I heard, the groups we're most worried about don't care whether they are identified. And as for getting caught -- the 9/11 hijackers didn't care about getting caught, 'cause their final reward would come with the act itself.

    As important as this research is, it shouldn't be confused with any sort of "prevention". That's the same sort of pre-9/11 thinking that made us think that planes were safe, because hijackers would behave with their own self-preservation as a goal. If your goal includes your own death, capture isn't a deterrent... if it includes spreading fear of your organization, identification is desirable.

    As a casual fan of science, this looks way cool for detecting viruses* that we already know about, by using the antibodies that attach to the virus protein as the detection agent. But aren't we limited to viruses for whom we've already isolated antibodies?

    I wonder how hard it will be to expand this into a more general virus detection/identification tool?

    My company has configured our PC-based/network-controlled Norton antivirus to be very aggressive in deleting possibly bad content. So aggressive, in fact, that it detected a virus signature in my Eudora .mbx file before Eudora had a chance to move the attachment to the appropriate directory. Poof! My whole Inbox is gone!

    The reply from Data Security: "Eudora is not an approved application. Get rid of it." This was back when Outlook would still auto-execute from the preview pane.

    Be careful what you ask for... you just might get it.

    * In the "just enough facts to be dangerous" department, they'll point out that its size can't be determined directly -- that it depends on assumptions about the planet's albedo. If it's darker than expected, then it'll be bigger than expected. Ergo, the scientists are conspiring (as usual) to make it smaller than Pluto. Their "scientific" conclusion: it's the brown dwarf companion to Sol that they've been predicting all along.

    Take board games as an example. How many ways can you move a playing piece from point A to point B? Isn't Life just the same as Monopoly, which is no different from Trivial Pursuit, which is an obvious ripoff of Chutes and Ladders?

    You get the idea. Those four games hugely different variations on the same "platform" -- a flat piece of cardboard. What's more, they're still around after decades. Monopoly keeps coming out with special editions that are no more than "different cars" in GTA-LXXVI -- but they still sell.

    And a stroll down Toys-R-Profit's game aisle shows a dizzying variety of board games. Many of them are lame variations on the theme (roll 1d6 to see if Barbie gets a good parking space at the mall) and won't last a year. But while they're around, someone will buy them, and next year we'll have another lame variant.

    What's sad is that we're seeing the end of the beginning. We 30-somethings watched video games go from homebuilt to primitive to amazing... to commodity. I expect the children of the 1860s experienced the same thing with board games.

    The funny thing is this article in the "related links" section: 'God particle may not exist'

    In that December 2001 article, we have statements like this: "Their conclusion is that there was nothing in the data at all to suggest the Higgs is out there - certainly not at energy masses of up to 115 Gigaelectronvolts (GeV), way past the level of 80 GeV where the boson was expected to show itself."

    Contrast with March 2004: "Dr Renton cites indirect evidence taken from observations of the behaviour of other particles in colliders that agrees with the figure of 115 gigaelectronvolts for the mass of the Higgs boson."

    The great thing, though, is how science done right is self-correcting. As soon as this boson was declared unlikely, researchers apparently began to attempt to prove that it did exist. Now that there's a theory that it exists, more researchers will begin trying to prove them wrong. Eventually, with all the facts out in the open, science will discover something approaching the ideal theory, which will likely be something unexpected.

    It's like Microsoft vs. open source... find a bug in Windows, and it takes 9 months to patch it. Find a bug in Linux, and someone will patch it the same day...

    Interestingly, I just listened to someone discuss the awesome power of a sight that fewer and fewer people have seen: nuking the Earth.

    On NPR's Fresh Air, former Secretary of the Air Force Thomas Reed talked about his new book, At the Abyss: An Insider's History of the Cold War. In addition to his policial role, he was for a while a "consultant to the director of Lawrence Livermore National Laboratory, a well-known center for nuclear weapons research." As such, he helped design nuclear weapons, and was present during their testing.

    He pointed out that witnessing an above-ground nuclear detonation was itself a life-changing event, and that the experience colored the decisions of all who saw and felt it. The light, he said of a Christmas Island blast, wasn't just bright -- it was all-enveloping, even through the way-beyond-dark goggles. And the instant blast of heat, that made you want to run away, anywhere, just to get away.

    But nuke tests are now performed underground, where the awesome power is visible only as instrument ticks and a dimple in the ground. As the old scientists die, there are fewer and fewer people who have witnessed a nuclear blast as it would occur in the above-ground world.

    The whole concept is so abstract, we can now discuss the idea of blowing one up on another planet, without even breaking into a sweat. Unfortunately, there are plenty of folks in the militaries of the world who can do the same sort of abstract thinking in reference to their own planet.

    Fair enough. Except I realized that when I signed up for Dish, I also thought some of the channels aren't worth paying for. But in this case, Dish sees things differently:
    Allowing customers to substitute channels or add a favorite channel to their package would force us to raise prices. To prevent this, we do not allow channel substitutions. We strive to make satellite programming as affordable as possible. Our packages have been setup in balance with cost effectiveness and consumer demand. One way to help keep our customer?s programming costs low is to provide stations in packages, rather than ala carte.
    Apparently, Dish wants it both ways. Packages are a great idea when Dish forces them on me, but not acceptable when Viacom forces them on them.

    The aforementioned 8-year-old got it right: "They're just fighting like 3-year-olds over a toy, aren't they?" And picking which side to root for is about as silly.
