    In your terminology, is there any circumstance under which objects in relative motion can be said to be 'aligned'? While I agree that relativistically speaking alignment isn't generally symmetric, I would have thought that this was exactly the situation in which one would have used the word - despite their limited speed, photon paths are the best 'lines' we have.

    Personal freedom, sound economic policy, measured intervention in things that won't look after themselves - isn't this what we used to call 'Liberalism'? All the Libertarians I have encountered labour under the delusion that they are universal experts and that nobody but them (least of all people with actual domain-specific training!) should be doing any resource allocation. They don't want to fund street repairs - in case someone else uses tarmac they helped pay for - let alone science. Certainly a total failure to grasp the notions of insurance and natural monopoly is de rigeur. So ... since you aren't a selfish fool, why do you label yourself this way? Is there some benefit?

    I'm sorry, I know I sound rude, but otherwise intelligent Libertarians are an endless source of frustration in my life.

    Except not. Inverse square has to do with the distance from the source, not the square area of the reflected surface. (An argument can be made that the area of the reflected surface has a relationship to the distance from the source, but it's not the same thing at all.)

    Except yes, because the relationship between distance and cross-section that you consider to be not-the-same-thing is a characteristic property of (flat) three-dimensional space. It's why we get inverse square laws as a default physical behaviour (or rather, inverse square laws and macroscopically 3D space are immediate consequences of the same piece of mathematics the details of which we're still working on).

    Or if you're thinking at a higher level of mathematical sophistication, notice that it's only in so far as the surface is normal to the illumination that we're doing any projection. Even by making strangely shaped surfaces you can't pack more projectable area into three space than the square law permits.

    The inverse square law only applies to an isotropic source - a light that's being emitted in every direction (like a candle). This is why lasers stay bright at a distance.

    All that matters here is light output divided by the square inches of the screen.

    When you say "light output divided by the square inches of the screen" - that's what we call an inverse square law. On account, you see, of the light output being divided by the square - oh, never mind.

  7. Re:Some State Laws Already Address This on Surveillance Rights for the Public? · · Score: 1

    Morally speaking, there is a huge distinction between third party and first party recording. Since other people have vastly better memories than I, I consider it a disability/accessibility issue that I should be permitted to record anything that I see or hear. I think this applies most especially to things that happen in official contexts, not so much because I am concerned about occasional abuses of authority (though I am that), but because conversations that happen in police stations, immigration offices, and government bureaux are often of high criticality, and the law will presume that I have knowledge of what transpired in my presence. Absent a memory or a recording I can refer back to, what use is it if I am informed of my rights? What help is it if I am given advice?

    But this is hugely different from the situation where someone's supervisor is scanning phone recordings after the fact, checking to see if perhaps I shared a dirty joke with a sales representative; or if I plant a recording device on someone to learn things that they have every right to expect are private.

    What then should be admissible as evidence? Everything that is evidence, of course. What is needed there is not a law that an inappropriately made recording is disregarded, but a mechanism to ensure that those who introduce improperly acquired evidence are punished for their crime in obtaining it. The right method of ensuring that the police obey the law is simply to make them subject to it. No strange artificial blind spots are required.

    Of course a recording may be edited. A verbal account may be untruthful, too. This is just one more thing that must be assessed in the course of a trial. A recording is just a representation of a memory, for all the technology involved. As with so many other issues of law, there's no need to mystify, here. The necessary principles were worked out centuries ago.

  8. Re:Ummm. on US Government To Release Electronic Passport · · Score: 1

    I'm being misunderstood. I'm not saying that there's no point in having passports for dealing with foreign countries (although if they adopt the policy that the US advocates, that their documents are checked before boarding for a trip, then in fact the same arguments do apply). But any electronic card passport 'replacement' would not be a conventional passport anyway. Furthermore, the claimed benefits are not benefits for foreign countries, either; they are benefits for Americans returning to the US.

    So, to try again: it's not that passports have no use, but all the new electronic IDs being tossed around recently can be reduced to serial numbers.

    As to the question of a DOS against the border posts—first, there's no need for them to use the public 'net, and second, I will bet you dollars to donuts that if the 'net goes down now and they can't check if you're on the blacklist, the border guards will not let you pass.

    What I really don't understand about the entire discussion is this: what the border guards actually look at is not what's written on your passport; it's what's stored in their database (from which, in the case of your own citizens, the passports were generated in the first place). So all that is needed is a serial number, right? You type your SSN into a keypad (or for that matter, swipe any one of your credit cards—nobody believes that the security establishment pays any attention to data protection laws, anyway), your photo pops up on the guy's screen, and if it's you, you're through. Everything else is either a holdover from the days before networks, or a diversion.

    So ... what's this really about? I ask this not as a tinfoil hat question, but because I'm truly mystified.

    I'll say it again. Now there's an Internet, you do not need to carry ID. The Man already has your file, and it's only because 'biometric' face recognition doesn't actually work yet that you carry any cards at all. There's no reason for cards to hold any data beyond a big number. There's no reason for them to be unique. There's no need for them to encode anything that can be used against you. There's no reason for any of this nonsense.

    The only motivation I can think of for these measures is so that they can charge you more application fees for the new ID. What on earth am I missing?

  12. Re:Flaming to get hits. on Copyright Cutback Proposed As RIAA Solution · · Score: 1

    Yes, of course. Copyright law serves a useful purpose in attacking corporate theft, but pre-Internet measures were already more than adequate in dealing with this. Indeed, it makes sense to scale copyright protections back in duration as social time constants shrink and the technical tools for enforcement advance, rather than extending them—though as I said before, it's important to keep pre-release copyright durations long enough to allow works to be completed. But be that as it may, things like the DMCA and the *AA wars serve no purpose in this regard.

    I'm not sure I agree with you about P2P, however. As I said before, I believe these things to be protocol details, and even saying that P2P tools is a misdemeanor is nonsensical; copyright is about content and not protocol. If someone places a copyright work on their server for distribution, have they done anything wrong? They have participated in a distribution medium, as a library would, for example, but they have made no copies themselves. People who already have a hardcopy of an object have (or should have) a fair use right to an electronic copy, and obtaining it by download rather than by ripping/scanning just makes technological sense. The only 'rights' that have been circumvented are self-help rights that have no place in a society based on the rule of law. People who do not have a right to a copy they make are in many cases infringing the owner's rights by doing so, but it is the download and assembly process, not the P2P protocol or even the uploading peer which does this.

    I seriously believe that in order to preserve and advance our culture, everything possible should be online in non-DRMed form. Authors and artists, both individual and corporate, still deserve our respect and support, but why cripple the Internet to accomplish this, when there are perfectly good laws already in place from many years ago?

    The biggest problem is the erosion of respect for the rule of law itself, and the *AA are complicit in this, as are those who say (with the parent of my original post) "we are the great US of A, why should we care about our legal obligations to our neighbours?"—and the framers of the DMCA, which above all else is legal protection for snake oil, in that it provides legal support for 'copy protection' schemes which in no way protect against copying. The © symbol already exists to alert consumers to copyright, and does not encourage fraudulent 'cryptography', or transfer control of consumers' hardware to corporate criminals (well, other than possibly O/S vendors).

    Five years is clearly too short a cutoff for copyright in general, since it can take much longer than that to write a book, and making it impossible to circulate drafts helps nobody. What's needed is anti-squatting measures where (as is done with book/journal copies made in libraries, I believe) payments for copyright, patents, etc., are made to a central authority at reasonable standard rates; and where 'strategic' obstructive practices result in loss of protection. If someone gets upset about a file or two on your computer (the issue that seems to irk slashdotters the most, though it is 'squatting' on pieces of mathematics and human biology that does us the most real harm IMO), then you can produce your hardcopy original or pay them their buck. It's fundamentally a less serious problem than having a turn signal that doesn't work—perhaps on the order of having an overloud party—and should be dealt with as such.

    Of course, as a separate matter, someone also has to educate the legislators that bittorrent is essentially a protocol, a method of allocating bandwidth, and not a business. I'm truly not quite sure how they've missed that point.

    As to your other point, about sovereignty, I'm afraid I have to point out that you are insane. In your house, who has sovereignty? You, the actual residents, or your neighbours? The answer is you, until you start acting like an asshole and/or breaking the law. When you start killing people, taking prisoners, or (in the present case) stealing people's stuff, the community comes into play—and rightly so. And no, it doesn't matter if you work as a cop (or think you do). The law applies to everyone. Stop whining and behave yourself!

Microsoft's profits come from a small range of technologies and philosophies that are often old at deployment, often weak by design, and fixed by the 'vision' of a small number of powerful people with strong personalities but extremely limited technical competence. Its strategy is to protect those profits, by limiting the extent to which innovation reaches the marketplace. This can be accomplished by destroying competition financially, by acquiring and dismantling competition, by obtaining (through patent law and, if necessary, research) exclusive rights to the technology that would enable competition, by hiring the researchers who might otherwise help the competition, and by actually innovating only as an absolute last resort. This is because change, any change at all, in a Microsoft product, is a tacit admission that the existing version is not already the best it could be. While to normal people progress is just the nature of the technological world, to the personality types who reign at Microsoft it means that they were ignorant and they were wrong, and this is very, very hard for them to accept.

I can't imagine that it makes much difference in this calculation whether someone is a cop or not, except perhaps in that the police are paid to deal with dangerous situations while civilians are not - meaning that a policeman's life may in some sense be worth fractionally less than someone else's, by their own choice.

    As to marijuana laws, I think this is a nice example that we can't get anywhere without more variety in verdicts. Along with 'guilty' and 'not guilty' there's a clear need for 'not proven', 'malicious prosecution' and 'the law's an ass'. This does raise the philosophical question of whether these should be mutually exclusive, since the usual case with marijuana is that all three of 'guilty', 'malicious prosecution' and 'the law's an ass' obtain - the law maybe moronic, after all, and the crime inconsequential and clearly beneath the notice of a policemen lacking other, less appropriate, motivation; but compliance is not something requiring any effort at all, except in a few exceptional cases such as chronic pain management.
