    You can pull as many adaptive whatchamacallits out of the signal processing toolbox, but that doesn't change the simple fact that certain wavelengths will be absorbed by the atmosphere before they even get to your ground-based telescopes.

    Certainly true, which is part of the reason newer space scopes focus on things like X ray or IR observation, rather than visible wavelengths. But, even at visible wavelengths, a space telescope can do some things a ground scope can't, like take a continuous week long exposure. A ground based scope can compensate somewhat with a bigger mirror, and thus accomplish a similar shot in a shorter exposure, but it just can't manage that kind of continuous observation. (And, to take a week long exposure with a ground based scope, you'd basically need three weeks worth of observation time, because you can't see that star you want during the day, or when it is obscured by trees near the horizon, etc.

    I think an old school mine would work better and do more damage to the intended target. I don't think you were modded "interesting" for the reasons you think.

    The issue is that while an old school mine could do more damage to whoever stepped on it, there's no particular justification for expecting that it was the intended target. If you want to be sure to get an American in a city full of your countrymen, you don't want to use a standard mine. You'll just kill your own side, and probably never actually hit an American. The issue with an RFID passport sensitive mine is that you can have it only blow when an American walks by. You could even configure it to trigger only with a certain threshold of Americans.

    And, you don't need them to physically step right on a small object like a mine. And, since you don't need any physical contact with the target, you don't need to have your weapon sitting out in the open where somebody can see it. You can hide it much easier. You don't need your own people to be near the bomb when it goes off like if you wanted to have somebody with a remote control watching for an American.

    I don't generally get in a huff about silly threats, but IMO RFID triggered mines in foreign cities targeting Americans would be a reasonable tactic. You need some power, but an RFID reader can run on pretty low power. You can probably get substantial lifetimes on battery. Worst case scenario - just plug it in. I'd expect that sweeping for an RFID reader would be pretty damned difficult, given the low power levels involved, and the fact there there will be similar legitimate equipment in the city as well.

    Geometric view interpolation is not unknown in the labs right now, and in some cases is being researched for exactly the reason you suggest. As another poster suggested, there are certainly some cases where the interpolation will break down. (Put a hand in front of each webcam at the side of your monitor, and it won't interpolate two palms to look like your face, for example.) Another one is that anything transparent makes it impossible to estimate the depth at a particular point because there are actually two depth values there. So, the smoke from your cigarette which is an amorphous volume of semitransparency through which you can see a window, the schmutz on the window, a reflection on the window, and something through the window will just ruin any chance of doing the interpolation properly. When you try to shift the pixel correctly to accomodate for the view shift, you get like seven different answers for what direction it is supposed to go.

It's currently becoming very popular for rendering multipass CG in the effects world, and basically it allows you to render one file which contains separate images for matte passes, diffuse shading, base color, specular lighting, reflection, etc., etc. The new workflows available make this technique suddenly much more popular. And, a lot of studios will render out 32 bit per channel instead of the 10 bit per channel listed in the table you linked. So, multiply the data rates at the top end of that chart by a factor of at least fifteen when talking about CG. Then double it because it'll be done progressive instead of interlaced. Then double it again because you wouldn't render to 4:2:0 - you'd render to 4:4:4. Then quadruple it because you want to work at 4k instead of 2k HD. Then, if you want to work at the high end in 8k, quadruple it again. (Though, not many people are currently working in 8k, and those who are do so at 24p, not 60p. So, the final quadrupling is probably unfair.)
