    1 can't happen.

    There's basically one place for energy to go besides heat on the planet. It can be turned into EM and sent outward, and some of it will make it. (Hence lighted cities from outer space.)

    Every other bit of solar energy that's turned into electricity eventually turns into heat, somewhere.

    As almost all the light that's sent into space comes from space in the first place, this isn't really a worry. One solar panel will block more light from reflecting off the dirt back into space than we could possible turn into EM and spend back into space.

    Basically, think of an air conditioner. Operating ten thousand air conditioners will not cause a city to freeze, because air conditions make things hotter on average. Likewise, solar panels make things hotter on average. All you've accomplished is to move heat around.

  2. Re:How to use the spectrum. on Spectrum as Property · · Score: 1
    Nothing in my proposal requires it to use the entire electromagnetic spectrum. Did you not read what I said? I said divide the spectrum into specific frequencies with specific powers attached to them, and then, and only then, let people broadcast anything they want, within those boundaries. (And following a sort of low-level network protocol.) When dividing out the new channels, it would be trivial to say 'Okay, we can't use frequencies X to Y, because they need that to look at the sky.' In fact, you'd have to do that for the military anyway.

    And it wouldn't cause more EM pollution, it would cause less, because we'd be able to broadcast at low powers and not worry about high-powered devices stepping on us on that frequency. Just like you can operate 1000 low-powered cell phones in the same area you can operate 40 CB channels...cell phones broadcast shorter distances, and thus take up less space, not more, in the EM spectrum.

    In fact, it's been pointed out to me that 'repeaters' shouldn't be talking to each other via radio waves, but via wires. At that point, this is basically the cell phone network, with the addition of direct connection between cell phones, and the replacement of cell phones with anything that uses radio waves. Come up with some economic incentive to operate towers, and we'll see all the cell phone towers turn into them.

    Of course, in a sane world, we'd be building our frickin observeries on the far side of the moon in the first place.

  3. How to use the spectrum. on Spectrum as Property · · Score: 2, Interesting
    It's easy, and completely impossible to impliment at this point in time.

    First, divide the spectrum into a million different slices. Specify some of them as high power, and some as low power, some as very long distance, some as fairly long distance, some as short distance, and a few as few very short distance, aka, bluetooth. (You need less as the distance gets shorter, because, duh, everyone can use the same ones.) OSI Layer 1.

    Next, come up with some protocol. It needs a sender address, an optional destination address, and data, and that's it. Include a 'logical link control' to let people move around at will. Automatically negotiate a 'backchannel'. OSI Layer 2.

    Then let anyone broadcast on any power/freqency, anything. But, and this is the key, require them to always negotiate downward to the 'worst' power/freqency that works, unless they have a good reason not to. (Aka, they're a TV station, and they don't want TVs to constantly have to call them back and say 'Hey, up the power a bit more.' Possibly you'd have to license this, but that's not important because most people would use devices that are bidirectional and thus don't need to worry about it, just the broadcast people.)

    But, remember, each frequency has a set power, so if they want to broadcast stronger or lower, they'd need to change power/freqency. And, yes, attennas are designed for certain frequences, so we'd need to have evenly distributed strong and weak ones. (Aka, for every antenna size, we need to make sure we have a 'right next to the tower' power/frequency we can broadcast, and a 'A strong as possible' power/frequency too, that we can both hit with that antenna.)

    Then build an assload of repeater stations. For any power/freqency, with the brains to let us link through them instead of directly. (In fact, if you have these, you can ignore the TV broadcast problem. Just have the TV station aim for these guys. If you can get it direct, good for you, if you can't, get it from them.)

    The problem is that we're trying to solve a technological problem with regulations. There's plenty of bandwidth for everyone. It's just that we build devices that can't move around to get more. If we stop that, if we build some sort of 'airnet' that lets me use a specifically designated low power/freqency when I'm right under a cell phone tower, but flip to what is currently UHF at near-TV station power when I need drive behind a mountain (Thus sucking all my batteries, but that's not important.), we'd never have to worry again.

    And, depending on how smart we design the network on top of this infrastructure, we can magically have cell phones and TV that can tune in radio stations, and direct-connect cell phones. Because there won't be any difference, except hopefully a layer of encryption on the cell phones.

    Actually, every device will need some encryption, or at least authentication. So every idiot can't wander around pretending to be CBS. But, hey, we now have a world-wide wired infrastructure to grab public keys off of. And, really, no reason we couldn't hand out keys over the airwaves...we'd just have to what happens with web browsers now. You can get a signed cert, or you can make your own. In fact, make this part of layer 2, also, just because.

    Of course, no way in hell this will ever happen...it requires throwing out all TVs and radios and cell phones and everything.

    Can vary. You don't pay twice as much insurance because you drive twice as far a week. You remember that 75% of accidents happen within 10 miles of your house? Well, that's a stupid fact, because that's where you usually drive, but most accidents happen before you get on or after you get off the freeway, aka, on 'surface streets'. 15 miles split into 5 three mile trips around the subdivision is much more dangerous than a mile to the highway, a 13 mile trip down it, and amile from the exit.

    While, yes, distance can affect your insurace, it doesn't determine your insurance.

    And the great-grandparent also completely ignored the average damage done in each accident. If a woman gets in a fender bender every six months, but a man totals someone else's car every year, guess which costs more?

Yes, IBM had the source code at the time, but they really didn't do a lot of changes. Think 'user-mode Windows', minus the hardware emulation. (Yes, Windows somehow managed to have direct access to your real hardware, which means that the OS/2 GUI managed to move out the way really quickly.)

    As for Win4Lin, it runs a standard version of Windows, but I could have sworn it loads said standard version into memory and patches it there. I can't find any reference to this on google, though, so maybe I'm wrong.

    WRT the memory space, I meant it was doing trickery to Windows, not Linux. I was under the impression that it didn't do the 'allocate X megs of memory to Windows and pretend that was all there is', but rather it basically made Window's allocate memory from Linux when it needed it, just like other programs. In other words, instead of the generic 'memory emulation' that VMWare does, it installed a memory 'driver' that just talked to Linux and got memory.

    Of couse, I've never used Win4Lin, so I could be completely wrong about all of this. This is just the impressions I got of the differences between it and VMWare. The way you're describing it, it sounds exactly like VMWare.
