    Or they can decide to ban prosthetic limbs just like doping, or at least spin it off into a separate competitive category. Something that you should know about Pistorius. He is able to run because he got his legs amputated as a child, so he still had the mental flexibility to completely relearn moving with prosthetic legs. These limbs also cost a shit load. In other words, the only way to duplicate his performance now is to chop off some 5 year old's legs and make him decide to run as a living. Serious. No one will be able to pull off a Pistorius for at least another 10 years.

  3. Re:waste of money on Lockheed Martin Awarded GPS III · · Score: 2, Interesting

    Lockheed also knows quite a lot about space and satellites. They built the satellite that the Hubble is housed in. They built the rocket upper stage that the Gemini went to space in, they built the Corona series spy satellites, and they built the Atlas V rocket. I'm sure there's more. As someone else pointed out, NASA generally doesn't build stuff. They contract out most things. Because paying companies who want to make money happens to be an excellent way to get stuff built.

  4. Re:How unfair... on Amputee Sprinter Wins Olympic Appeal to Compete · · Score: 2, Interesting

    You have to flex your ankle to use them as springs. He doesn't. If that doesn't convince you, consider this. When you squat up and down, your legs essentially work like springs. Squat up and down. You'll get tired around 20-30 reps. Now imagine an actual spring. It does not get tired.

  5. Re:So where do you draw the line ? on Amputee Sprinter Wins Olympic Appeal to Compete · · Score: 1

    No. But that is a false analogy. Laser eye surgery at best will not allow to see better than the human maximum, nor will it allow to see in a fundamentally different way. Pistorius' legs do. His efficiency is beyond the reach of any human, simply because he doesn't have to flex his large segments of his leg when he lands each stride. His race performance bares it out. He maintains an almost constant top speed for the entire race, something that is impossible for any human runner. His legs are BUILT for running. They are nearly impossible to balance on when walking or standing still. They are almost literally springs. This would be more like giving a shooter a scope, and adjustable laser pointer instead of laser eye surgery.

  6. Re:this is ridiculous on Amputee Sprinter Wins Olympic Appeal to Compete · · Score: 4, Informative

    Normally when running, you tense up certain muscles just before foot strike, so your muscles acts like a spring to release part of that energy afterward. Normally, this means that you get tired cause your muscles are constantly in use (active energy storage). His legs are so set up so that they passively store this energy. He does not need put any effort into that part of the stride.

    Not only that, the leg below the knee's importance in sprinting is relatively minor. Aside that the ankle/calf acting as an active shock absorber, nearly all the leg's energy is spent in the upper leg to drive the entire leg forward. His legs are considerably lighter than real human legs, and very much does make him run completely different.

    Pistorius really does run differently. Because of the way his legs are constructed, his maximal running speed may never reach that of an unamputated human being, but his efficiency is beyond anything anyone else can achieve. He's running speed (measured in 10m segments) is far more consistent then any other runner, because he can maintain his full speed for much longer and with relatively less effort than anyone else.

    This is not to say that he is an amazing athlete. He is. He has overcome incredible challenges, and he deserves recognition. But he does not belong in the Olympics the way that they are formulated right now. His artificial allow him to achieve feats of efficiency that simply cannot be reached with any human body no matter how well born and trained. I feel that many are letting themselves being clouded by the emotional aspect of this issue, and ignoring that this would be like letting someone on rollarblades grafted onto their feet compete in a standard track event.

  7. Re:Easier for totalitarian govts, but not better on China Buying US Directed Sound 'Weapon' · · Score: 1

    Because very little people inside China knows what actually happened. China doesn't really care what the rest of the world knows, as long as it can keep it away from it's own people.

  8. Re:Mixed feelings on this on China Buying US Directed Sound 'Weapon' · · Score: 1

    Not only this, China IS undergoing an incredible economical boom. The country, and nearly everyone in it is getting richer. There are opportunities for almost anyone to try to get in on the money. The Chinese government regardless of its social liberty has become significantly more economically more 'free' than in the past. It's kind of hard to argue against a government that A) you have been taught is the best government in the world and B) Is making your richer.

    Depends what he made the wing out of. If it was fiberglass and/or composites, then probably not very well. If it was metal construction (I don't think it is), then it'll show up fine. It flies at like 200mph max I guess, so it reenters the realm of human aimed guns.

  16. Re:Well since no one else will say it... on USAF Considers Creation of Military Botnet · · Score: 1

    What is destroyed by a botnet? What human lives are put at risk by overloading computers? As someone else stated, key systems should not be on the internet in the first place, while those which remain would certainly cause disruption, but no directly caused deaths. Consider that fact that we've managed to live 100 000 years as a race before we had the internet and computers. We managed multi-million population cities for at least half a century before the internet. This is hardly a weapon of mass destruction. WMD does not mean indiscriminate weapon. All weapons are indiscriminate. You get hit by a bullet, bomb, sword, or rock, you're going to die regardless. You get hit by a botnet, and you're severely inconvenienced.

  18. Re:Great on A Billion-Color Display · · Score: 2, Informative

    I think the grandparent was talking about color resolution not angular/optical (or is it something else?) resolution. There is no arguing that human eyes are fundamentally limited by our lenses, and that gives us a pretty much fixed benchmark for maximal human sight in one measure. But when it comes to distinguishing colors, human vision is far less concrete. The fact that we have an auto adjusting white balance should be enough proof of that.

    Get a 1024 pixel high/wide image. And then make a perfect white-black gradient. You should be able to tell between the two.

    Furthermore, a soldier's role on the battlefield is to achieve an objective. In general, this object involves removing the enemy. The general way to do so is to either kill them, or make them surrender/give up. Sometimes the situation is such that by killing a few selective people, you can make the group give up. Other times, you just have to kill everything coming at you, cause it's the only way. In all cases, better intel means less risk for the grunts. Sure, its not exactly fair. But that's not really the point of war is it?

    It is absolute alright to kill with ever increasing efficiency on the battlefield, providing that the killing is just. If some group of crazy people tried to attack me, I would expect no less than the most efficient way to kill them back. The justness of a death has very little with how 'efficiently' it was carried out. Murder by pointy stick, and murder by bullet is all the same.
