    SDI worked, it defeated the Soviet Union. That was all it was intended to do. For all the risk that nuke wielding terrorist nations, and even China, might pose, that's a tiny percentage of the thousands of nukes that the USSR had ready to go. (Sure, Russia still has plenty of those, but they are far less likely to use them. We're not exactly worried about Britain or France's nukes, either.)

    They'll build bigger missiles or lighter warheads. ... The best way for them to increase that number is to just build more nukes,

    All those approaches cost money. Lots of it. Nuclear and missile technology is expensive, especially if you want it to work when and only when desired. It also takes time to develop and deploy. Buying time is worth doing, because the rules of the game may suddenly change (as witness the USSR in the fall of 1991).

    As for whether it would "really" work if push came to shove, that's irrelevant. As Sun Tzu tells us, defeat occurs in the mind of the enemy. If he believes the defense may work well enough to spoil his offense, he will not launch it. If he doesn't believe that and launches an attack, then even if the defense turns out to be an amazingly 99% effective (nothing is 100%) we have a mess on our hands. (And the enemy is toast.)

    Those are pretty damn funny! I note you didn't discuss the effect on the launch vehicle, i.e. the engineering effort to get some of your gizmos to actually work.

    And none of your techniques (save the last, sort of) address boost-phase intercept (eg by airborne laser or orbital-based kinetic interceptor.)

    1 - That will nicely fry the rest of the attacking missile fleet electronics and the neutron pulses may well mess up the fissionables in them. You basically have the attackers do a self-inflicted Spartan/Sprint (look 'em up) defense on themselves.

    2 - Warhead heat shields fail from thermal shock, warheads disintegrate on reentry. And, lookdown sensors from satellites see very obvious cold spots against the warm background of Earth and relay the coordinates. And, the LN2 plumbing (and LN reserve) reduce the payload, thus range, of the LV.

    3 - Again, multiple sensors in different locations have no problem differentiating flares from RVs, and the weight of the flares and ejection mechanism reduce payload/range. Flares do NOT weigh "almost nothing", neither does the ejection mechanism. If they do weigh almost nothing, they'll lag behind the RV as soon as it hits upper atmo.

    4 - Only "a little bit of engineering". Clearly you're no engineer. It adds weight (reducing range and payload), it really messes up targeting (oh well, if the nuke targetted for Los Angeles detonates in Death Valley, no big deal). Some of the designed and tested kinetic interceptors deploy to a rather large structure a lot bigger than "a few yards".

    5 - Clouds in vacuum disperse pretty damn quickly, both from internal and sunlight pressure. And the denser LV will soon leave the cloud behind in the extreme upper atmo. Besides, the cloud disperses predictably, so we just have a bigger target for the interceptor to aim for the center of. (If the cloud is dispersed directionally, again you've messed up the warhead trajectory and targetting.)

    6 - Now that really messes up the targetting, especially if the tether breaks (or is broken by the interceptor). Deploying it is no engineering triviality in the few minutes of ballistic coast that the warhead has, either.

    7 - Inflatable decoys are trivial to differentiate from the real thing, even if you manage to give them the same thermal characteristics (careful choice of materials, paint, etc) they react differently to sunlight pressure, atmospheric drag (even very tenuous), or being pinged by a laser beam.

    8 - An intercontinental missile is always going to be more expensive than a much smaller interceptor. You need to add in launch and command infrastructure on the attacking side, too. If you go the cheap route and base your decoys at obviously non-nuclear missile launch facilities (consider the relative security and command and control infrastructures), then the defender can ignore missiles tracked as launched from those sites.

    9 - Yes please! That greatly simplifies the interceptor's job -- just home in on the strobe lights and radar transmitters.

    10 - Again, rockets launched from known decoy sites can be ignored. If you want to convincingly make a decoy site look like the real thing, it's going to cost as much as making the real thing.

    Nobody is claiming that a missile defense would be 100% effective -- any more than a bulletproof vest is 100% effective. But if someone is going to be shooting at you, you'd probably want one. Further, protective gear (or missile shields) are effective against accidents or single (or few) shot attacks.

    Nothing is going to significantly protect against an all-out attack (although the severity can be reduced), the only hope there is to discourage the attack from being launched in the first place. This is much easier to do if the attacker knows that a significant portion of the attacking missiles won't make it to their targets, and that he cannot prevent a certain, devastating retaliation. Ultimately the potential attacker has to be convinced that he has more to lose than to gain by attacking.

    Unless you know what the OS is doing, you don't know that it isn't diddling with the data every time you make a system call to e.g. save that data to disk.

    Now, if it's an off-the-shelf OS, it ought to be possible to wipe the voting machine clean and re-install with some other copy of the OS plus the app, and have it work the same. That's testable.

    Of course if there's any chance of collusion between the voting app vendor and the OS vendor ("if memory location X is set to 1234, then system call foo() will do secret behaviour Y"), then the OS has to be open.

    I don't think the state regulators care about the OS but rather the software used to control the voting machine.

    Given that it costs orders of magnitude more to defend against an ICBM as it does to build one,

    That's far from a given. There are many ways to interfere with an ICBM attack, THAAD is just one, and is one of the last resorts if other methods (airborne laser attack on the ICBM booster, coast-phase interception, etc) let something through.

    The point, though, is that it messes up the attacker's planning. He can no longer count on every ICBM (less normal malfunctions) getting through, he has to figure that only some percentage will get through, and some targets may not be hit at all. This raises the stakes considerably -- a knock-out first strike becomes impossible, unless one is willing to spend the money on enough more ICBMs (or to toughen them up to resist counter attack) to again give the attacker overwhelming odds.

    Not to mention that countermeasures against the defense system are trivial,

    Right, don't mention that, because it isn't true. That canard was trotted out in the 80s, and some of the suggestions were positively ludicrous. (For example, it was suggested that defending against boost-phase laser attack was simply a matter of "spinning the booster". Consider the dynamics of a rapidly rotating cylinder of liquid fuel (as were Soviet ICBM boosters) on top of normal launch stresses. No laser required, the thing would probably disintegrate of its own accord. Decoys? Yes, please! To fool modern sensor technology, the decoy has to be roughly the same shape and mass as a real warhead -- so every decoy launched is one less real warhead for a given launch capacity.)

    The cold-war defeat of the Soviet Union was exactly for this reason: they couldn't afford the spending to maintain their ICBM force at their desired threat level in the face of the various defensive strategies.

    Now, you have a valid point with "we're sending them $Billions more resources every quarter in exchange for trinkets", which certainly wasn't the case with the Soviet Union. We could hope that this raises the standard of living of the Chinese to the point where they feel they have too much to lose themselves to start a war, but given the totalitarian government, there's no guarantee. Meanwhile, given a choice, try to avoid buying Chinese goods. (Yeah, good luck.)

  13. Re:Dinosaurs aren't really reptiles. on Grass Grazing In Dinosaurs Confirmed · · Score: 1

    If you consider birds to be (even if via dinosaurs) reptiles, then clearly such minor physiological characteristics as endothermy vs exothermy don't enter into it. Sure, if you're just going by the number and location of holes in the skull, then dinosaurs (and thus birds) are reptiles.

    But to most people -- and granted it's a lay definition -- a reptile isn't determined by the makeup of its skull but by being a vertebrate that is (a) cold blooded, (b) egg-laying and (c) more or less scaley (no hair or feathers). (And differentiated from amphibians by not having an aquatic stage or by laying eggs on land). Birds certainly don't qualify under (a) or (c), and it's becoming more clear that many -- perhaps most -- dinosaurs didn't qualify under (a) and some not under (c) either.

    No doubt much of the resistance to the latter ideas is due to calling dinosaurs "reptiles" and the consequent image of a dinosaur as a rather large but yet cold-blooded scaley (or at least, featherless) beast. This masks (in popular perception) the gradual transition of vertebrate species over the last couple of hundred million years -- there's a perceived "giant lizards to sparrows and pigeons" transition at the K-T boundary, which makes evolution harder to grasp.

    (I'm no paleontologist myself, although I spent many hours amongst the collections of the ROM in Toronto as a kid. One of my 7 year old boys has wanted to be a paleontologist since about age four, and can probably recognize more dinosaur species than I can.

    Certainly not in the sense that most people think of reptiles (snakes, lizards, etc). To say dinosaurs are (or rather, were) reptiles, you might as well also say that birds are reptiles and even that mammals are reptiles (descended, as they are, from mammal-like reptiles like cynognathus or dimetrodon, and indeed monotreme mammals still lay eggs).

    Indeed "dinosaur" itself is a rather vague catchall term, meaning anything from "any Jurrasic to Cretaceous animal not obviously a fish, bird or mammal" to its more technically correct meaning "a member of the order Ornithischia or Saurischia, and certainly excluding pterosaurs or pleisiosaurs".

    Alas, we're pretty much stuck with the imprecise terminology that was first popularized. Consider how surprising the article would be if the title were "Grass Grazing in Therapods Confirmed", vs the more accurate (given TFA's contents) "Grass Grazing in Sauropods Confirmed".
    If they'd found grass in Tyrannosaur droppings, I'd be amazed! (As it is, evidence of late Cretaceous grass is still surprising, conventional wisdom is that grasses arose in the Tertiary.)
