    Anyway, as a region of space gets denser, time slows down, and as the density approaches the density required to become black hole, time just freezes.

    What you will see when looking at a "black hole" is just a region of space with the eventual event horizon of the hole just frozen in time, and as you move outside, time goes through the "molasses" stage, and as you get further away, gets normal.


    Erm, no. See, the perception of time dilation is with respect to the frame of reference of the observer, not of the thing observed. You don't look from a region of low density space into a region of high density space and "see" that their time has slown down.

    If you were outside the black hole observing, then you would see the black hole form instantaneously. Only from the perspective of the black hole's event horizon itself would time be stopped.

    But it would still form -- the "stopping" is only in a relative sense to other frames of reference. The black hole would still form, the perception of the speed at which this occurs is all that varies, and it would be quite fast for anyone observing from "normal" space.

    Nothing is more sickening then the nation getting duped into believing that there are exactly two sides to an issue and that "their" side always shares there opinion while the "enemy" is always wrong and blatantly evil.

    This is why I never join any "club" whether a religious group or a political party or whatever that expects me to tow the line on every issue they're concerned with. Which is every political party (and most religious groups), so I'm not in one. I never agree with anyone 100%, and I'm unwilling to sacrifice my ability to dissent just to feel like part of a group.

    Finally, I know it is almost pointless to bring it up, but I will anyways. The truth is that you have absolutely no idea if the Iraq war is being won or lost. If you looked at the Korean War or World War II and charted the body count, you would find that the closer to victory that the US got, the higher the body count for both sides. The most horrific and bloody battles of World War II were right before the end.

    That's because a lot of the biggest and most decisive battles that involved the capture of key pieces of terrain were right before the end. This is obvious if you look at the strategic position near the end of the war, and without knowing anything about body counts one would still expect them to be higher. Anyone who looked at that strategic position would say that the war was going well for the Allies. This is not the case in Iraq.

    Iraq is not a war like World War II. Word War II was a conventional war between nation-state militaries, Iraq is guerilla warfare conducted by disparate groups, some of whom work together and some of whom hate each other. Things like capturing key pieces of terrain mean nothing -- we're occupying the exact same space that we were in 2003. Increasing body count means only one thing: guerilla attacks are becoming more effective. That is not a good. If those lives came at some benefit, aquiring a key strategic location, or hobbling a key unit of the enemy forces, then you might be able to say it is a sign of good things to come. But it isn't. It's just soldiers being killed in their patrols, in their barracks, doing their day-to-day duty that will be the same tomorrow as it was today.

    "Loss" and "victory" in such a situation are difficult to define. Again, this isn't WWII, where we roll into Berlin and the German government has basically no choice but to surrender. We already occupy Baghdad, and all that means is the guerillas know where to find our troops. When we kill an insurgent, we aren't just eliminating a combatant but inspiring others to sign up against us, often more than we killed. When we drop a bomb and kill innocents, the people we are supposedly there to protect, it is not the same as a bomb dropped on an enemy power's city. One makes a victim out of the population of your enemy. The other turns an alleged friend into an enemy. Productive, vs counterproductive, because it's a conventional war vs an unconventional war.

    It is unclear that there is a military solution to an entrenched insurgency that doesn't involve genocide. Our current military strategy, which of course would not condone genocide, does not appear to be working.

    I do know that anyone who claims to have a crystal ball and can see imminent victory or failure is a stupid fucking ideologue with the historical perspective of a gnat.

    Well, okay, it's true that you can't say that failure or victory are imminent, but it is obvious that it isn't going well to anyone who isn't an idealogue. Arguing that we can't know that Iraq is going badly by making Iraq out to be an analog of WWII when it has basically nothing in common shows a lack of historical perspective, so just be aware before you fall into the same trap.

    The Republican Guard was serious. No, they couldn't stand up on the open field to our ground forces. That's why after we took out three divisions outside the capital, the two divisions guarding the city itself vanished and the Battle of Baghdad never occured. But two divisions of dedicated soldiers don't really "vanish" -- who do you think formed the foundation of the insurgency that took hold days after we declared victory? The Republican Guard isn't just fanatical, they're smart, and "fighting fair" when you know you'll lose isn't very smart.

    It certainly does not mean having more fun with the copyrighted work than the owner wanted to allow you! If he says you can only play it on a certain device, that is his right. That is fully protected by copyright.

    No, it isn't! The copyright owner does not in general have any say over how you use the work. That includes playing it on any player you want to. No, they don't get a say in that. Yes, you can have more fun with the copyrighted work than the owner wanted to allow you. That isn't "fair use", it's just use. Use is not covered by copyright.

    You will notice that the line you quote says that "fair use is any copying of copyrighted material" and then goes on to list things that do in some way involve copying and making derivative works of a copyrighted act which would normally be prohibited. It doesn't list "having more fun with the copyright work than the owner wanted" because that has nothing to do with copyright and hence fair use. So you're right it isn't a good example of fair use, but it is also not a good example of something the copyright holder has the right to prohibit.

    To be clear, there are three classes of "uses":
    1) Those prohibited by copyright, such as distributing copies or making derivative works or public performances.
    2) Those which are nominally prohibited by copyright, but exempted under "fair use" clauses.
    3) Those which are not prohibited by copyright and thus do not need to be exempted by fair use.

    The problem with DRM is that in the name of protecting 1, it prohibits both 2 and 3.

    Of course the ones who are heavily invested in DRM see this as a feature. It allows them to enforce whatever crazy restrictions they want, like limiting the number of times you can listen to a song or charging you rent for songs where they can stop you from listening to the songs if you stop paying, but they are not given the right to create those restrictions based on copyright law. However because DRM enforces copyright law, and DRM also enforces these other restrictions, it creates the illusion in peoples' minds, like yours, that these are all covered by copyright law.

    Well, they're not. Look it up. You will not find anything in copyright law empowering copyright owners to limit the number of times you listen to a legally acquired copy of their song. Copyright law only empowers the copyright owner to say who may or may not distribute the song. That's it.

    By the way, it is legal for someone to distribute a copy of a work with certain stipulations like "you have to return this to the store by Thursday at 11pm", but that's a contract, and it has nothing to do with copyright law.

    But being able to play content in different ways than the copyright owner wanted you to? No way is that fair use. He has every right to be able to charge you extra for that right, just as with other ways of enjoying his work.

    Again, that is not fair use, but it is also not a violation of copyright. He does not have every right to charge me for the right to play the content in different ways, just as he does not have the right to prohibit other ways of enjoying his work. If Stephen King doesn't want me to use legally acquired copies of his books as toilet paper, guess what? Tough shit for him (and tough toilet paper for me, but that's not the point).

    "Not as toothless" is not the same as "secure". A camcorder is just an example of the most basic, everyone-can-do-it method of duplicating the "message". With more sophistication you can duplicate the content quite reliably. The problem is that you have to present an unencrypted version of the content to the user. Let me repeat that: You have to present an unencrypted version of the content to the user.

    On a more practical note, it is already possible to simulate the operation of a TPM chip. It is possible to install a "Trusted" operating system on a simulated computer with a simulated TPM chip. Once you do that, TC is broken. I discussed this possibility with a coworker of mine, who was largely responsible for defining the processor's interaction with the TPM chip. He admitted that this sort of attack is and always would be possible, but required enough effort that the media companies were not worried.

    It has been and always will be about making the amount of effort required beyond what the casual pirate will be willing to do.

    However it is the DRM that prevents you from bypassing the iTunes software and its behavior by using some other software that does not have the same limitations.
