  2. Understanding Quantum Entanglement on Shining a Light on Interplanetary Communication · · Score: 5, Informative

    Here is how so-called photon "teleportation" works. This should explain why nothing happens faster than light, and why otherwise this isn't causality-destroying voodoo.

    You have a source that spits out pairs of polarization-entangled photons. Each particular photon is random -- it'll either be "horizontal" or "vertical" with 50% probability each. But, entanglement means that when one member of each pair is vertical, the opposite member of that pair is horizontal, and vice-versa.

    Because of the way QM works, we can't know the polarization of any particular photon pair in advance -- we only know when we pass the photon through a filter and then try to detect it. Both the filter and the detector change the photon, though, so any photon that we measure becomes completely worthless to us thereafter.

    So, we know that our photon pairs always have opposite polarization, but we don't know the exact state for each pair in advance. Now, let's cheat a bit and peek behind the veil, pretending we know the state of each photon in a sample stream. I'll use a 0 to encode one polarization state and 1 to encode its opposite:

    Stream 1: 0010110101
    Stream 2: 1101001010

    Now, right off the bat, suppose we read Stream 1 here and send Stream 2 to Mars. By looking at the values we read locally, and flipping each bit, we know what data Mars will receive. But, there's no way we can inform Mars of the contents of the bitstream ahead of time, because nothing travels faster than light.

    So, what's all this quantum teleportation stuff about? Well, it's like this. Our Stream 1 and Stream 2 above are random, so they're useless to us for transmitting anything but white noise. But, we can do a cool trick and transmit information in that white noise. We can't exceed lightspeed with it, but we can guarantee that the information can't be undetectably intercepted.

    Let's add in Stream 3, which contains data we want to transmit. I pick an arbitrary message -- suppose I want to send alternating bits, like so:

    Stream 3: 101010101010

    Now, I want to send Stream 3 to Mars, but I want it encrypted in the randomness of Streams 1 and 2. To do this, I read in Stream 1 and perform an operation on each result based on the contents of the corresponding bit in Stream 3: whenever a bit in Stream 3 is a 1, then I flip the result that I read in from Stream 1. Otherwise, I keep the Stream 1 bit unmodified:

    Stream 1: 0010110101
    Stream 3: 1010101010
    Stream 4: 1000011111

    So, Stream 4 now contains the data I want to send, mixed with the randomness in one of the two entangled streams. By itself, Stream 4 is meaningless. Also, Stream 1 has been destroyed by reading it. So, I can only decrypt Stream 4 using the data I have from reading Stream 1 -- or by using Stream 2.

    Now, I send Stream 2 to Mars unmodified. Anyone reading that stream destroys it and gets random data out of it. Using a separate beam, I send Stream 4 to Mars. Anyone can intercept this and get the data out of it, but it's useless without Stream 2. At the receiving station, they can combine Stream 2 and Stream 4 using a variation on the rule used to encrypt the data, to learn the contents of Stream 3, and they can be guaranteed that the data wasn't intercepted without them knowing about it:

    If someone intercepts Stream 2, reads it, and substitutes in another random photon stream, then the decryption on Mars will fail, and so the interception will be detected. If someone intercepts Stream 2, reads it, and manages to make a passable copy to beam to Mars, the time delay will be detected. (Not only that, but QM "no cloning" says you can't make a good enough copy anyway.).

    In all of this, nothing at all is happening faster than light. The veil of QM simply says that we can't know the contents of Stream 1 and Stream 2 until we measure them. When we do our encryption operation, we are putting useful data behind that veil, and when we "teleport" the data to the destination, we are getting it back out from behind that veil. But we still have to send everything at light speed.

  4. A Cow Says "MOO!" on Coding is a Text Adventure · · Score: 4, Interesting
    MOOs were like chat rooms, except the members of the community could create new objects by programming them into the virtual world in a dedicated programming language, shaping the game as it went along.
    MOO is interesting for a lot of reasons. It merges the concept of an object in the programming sense with the concept of an object in the game world sense, and it merges the concept of a method call with a game action.

    For example, you might instantiate a class, and the object created then becomes an in-game object that you can manipulate like any other. It inherits its data and behaviors from its parent. But, that object is also a class that you can extend, and others can be instantiated from it.

    In MOO, when you type a command, the game engine matches your command against "verbs" (methods ) found on the object representing you in the game world. The first word of the line you typed becomes the command to match, with the rest of the words being parameters. (You can also specify that verbs not be matchable, only allowing them to be called from within code). It's possible to have verbs that work either as commands or are callable from within other verbs.

    If you want to add a new command to yourself, you just add the verb and program it. If it's something to be shared, you copy it to an appropriate ancestor, then delete your own copy; you and everyone else inheriting from that ancestor gains the command. (There's security in place; if you're an administrator you can do anything but if not then you need the cooperation of the owner of that ancestor object or an administrator.)

    Ultimately, a MOO is just a scripting language and virtual machine, with a network interface and some security features to allow collaboration without granting all programmers full read or write access to each others' code and data. Implementation of the player / room / carryable object paradigm is done in the scripting language, not the engine itself. It's flexible enough to write Web servers in, and pretty damn fast for a language where everything is late-bound and weakly typed.

    Interestingly, while most MOOs used internal mail and public forums, and would send email for various purposes (coded right in the scripting language), and many of them listened for HTTP connections and translated part (or all) of the game world into HTML, none of the efforts to create large MOO networks (a la IRC) ever got very far.

    Fuck television stations. Fuck advertising revenues. Fuck people in general, because they've allowed marketing in general, including advertising, to completely brainwash them.

    In the U.S., most over-the-air broadcast channels and all of the non-premium cable/satellite channels fill up every hour of airtime with 20 minutes of advertising. And most idiot Americans who watch four hours of TV a day put up with it, getting fatter on their lazy asses, letting those precious minutes of their lives melt away into oblivion, passively taking in messages about products they don't want and don't need and probably will buy anyway and then let go to waste.

    Suppose you watch just two hours of TV a day, five days a week, for your entire life. If you live 70 years, that means you will have wasted away four years of your life passively putting up with marketing people's pandering to your baser instincts and treating you like a sheep to be shorn of a little wool every now and then.

    Just think! You're eighty years old on your deathbed, senile, drooling, with a nurse to put a bedpan under you every now and then and to sponge the stink off your decaying body. In a rare moment of lucidity, those four years hit you like a ton of bricks and the shock of all that time simply wasted causes your weakened heart to burst, hastening your demise.

    Time is the one thing we can't get back. Now, I firmly believe that television entertainment is an enriching way to spend some time. At the very least, if I choose to watch a couple hours of it, that's what I've chosen to do with some of my time. Giving up a third of it to stupid advertising is simply horrid; time is more valuable than money. You can always work to get more money, but there's no putting more sand into the top of the hourglass of your life.

    Ever since the invention PVR, I absolutely refuse to watch TV that isn't prerecorded, and I skip commercials religiously. I recover 20 minutes per hour of TV watching time. If I choose to waste those 20 minutes, then at least it's my choice, and it's not time given up to some faceless machine who thinks I need a new deodorant.

    Why the hell do people like spam filters, popup blockers, and commercial-skipping time-shifted television? Because somewhere deep down inside those coagulated lumps of protein people call brains, they realize that their time is the most precious thing they have; and that anything that diverts their attention from what they really want or forces them to waste their time doing something they didn't sign up for is a soul-sucking parasite threatening to drag them down further towards the bottom of the cesspit that is the human condition.

    I'm glad that the big entertainment companies are finally starting to get with modern technology. Nowadays you can buy an entire season of a show on DVD, not long after it finishes airing. If you're patient, you can get the whole thing commercial-free (you don't even have to be alert with your remote to skip the evil time sink commericals!) at a really cheap price per episode. Now you can get individual shows on your video iPod. How I look forward to the day when I can just order the programming I want, watch it when I want, and not have to put up with all the insipid adverts.
