  1. Re:Major source of corruption is Tax Code not PACs on Steve Wozniak Endorses Lessig's Mayday Super PAC · · Score: 1

    One reason why a progressive tax system is a good thing is the following: In general, you can get a higher appreciation on your assets if you have more of them. In other words, the richer you are, the faster you can increase your relative wealth. If you set up the differential equations for this, you will notice that the system is unstable, and will asymptotically reach a point where very few own almost everything. A progressive tax system counterbalances this effect, so that there can be an stable equilibrium where some are richer and some are poorer.

    Incidentally, this kind of concentration of wealth to a small elite is exactly what we have been seeing in recent decades. Because in practice, the tax systems in most countries aren't really progressive all the way up to the top. If you are rich enough, you either get your income through other means than a salary, which is then usually associated with a lower tax rate, or you escape taxes through more creative measures, like moving your assets to a tax haven.

    What people are saying here is that those claiming that increased gun ownership leads to lower crime rates are using utterly flawed logic. That does not mean that they necessarily argue for the opposite position. In fact, the person you responded to explicitly said that "I'm not arguing for one side or the other".

    Why is it so freaking hard for people on Slashdot to understand the difference between a counterargument and making the opposite claim? There is such a thing as "we do not know".

  3. Re:War of government against people? on America 'Has Become a War Zone' · · Score: 1

    The burden of proof is on the one making a claim. So when someone wants to claim that gun ownership does not increase violent crime, that person has to prove that claim just as much as someone claiming it does. Pointing to other plausible compounding factors is a perfectly valid counterargument. You then have to eliminate those alternative explanations, just like Copernicus had to for his theory to survive.

    You are of course correct that it is a very weak counterargument to simply say that "there could be explanations". But that is not what the GP did. The GP did propose a whole list of other factors that could affect violent crime rate.

    By the standard you are setting, nothing is ever disproved, because there could be variables which have not been taken into account.

    It's more like "nothing is ever proven", which would be a more or less correct statement with regard to science. It is all about trying to come up with inconsistencies or alternative explanations. When you have thrown everything you've got at the theory and accounted for it all, it is usually accepted.

    They use stereopsis for coarse scale depth and photometric stereo (three directions from the looks of it) for finer scale structures. And they seem to be using some tracking target to compensate for motion between these captures. Not a bad idea per se, but I don't think their numbers are particularly remarkable.

    I'm not aware of any 3D capturing technique that captures an object "from all sides", unless it's comprised of multiple individual scanners who's data you then stitch into a single model, or a moving scanner (relative to the object's reference frame, so the object could be the one moving), in which case you're really building the model out of lots of tiny scans at different positions (e.g. sheets). In principle, either of these are more or less orthogonal to the choice of scanner. You could do it with this scanner; you'd just put them all in a box and calibrate the extrinsic parameters using some reference object.

    The only things that I can think of that could be remotely considered scanning from "all sides" would be something that penetrates the object, like an x-ray CT scanner, ultrasonography or something of that sort, but that would be stretching it.

    After having read some on their website, I get the sense that the primary novelty of Fuel3D is not the technology, but who they are marketing it towards. There are plenty of scanners, like the ones you mention, that have equal or better performance characteristics, but they pretty much always seem to be marketed towards either medical applications or manufacturing industries. Fuel3D, on the other hand, have the slogan "Fire up your creativity", visit Maker Faire, and so on. I imagine they hope to break into an emerging market segment before the other guys catch up.

    Also, calling their accuracy, by which they mean noise level on a perfectly flat surface, of 0,3 mm on a 35 cm (diagonal) field of view "extremely high resolution" is quite a stretch. High compared to other cheap scanners, possibly, but at least an order of magnitude worse than industrial scanners of similar format.

    I think it is an interesting concept to combine photometric measurements with geometric stereo in a single handheld unit, trying to get the best of both worlds, so to speak. But it certainly feels like they are overselling it.

    Well, as far as Git is concerned, that would be rather pointless, considering that committing in Git simply means copying an already saved file to a different directory locally. The only thing that protects you from is accidentally messing up the contents of the file and then saving it. And that is assuming that the IDE keeps the entire string of commits, instead of squashing them, creating an insanely bloated version history.

    As is the case with builders of pretty much any sufficiently complex system. The number of decisions and assumptions going into any reasonably advanced software is astounding, and the time spend on each of these is comparatively rather small. Furthermore, compared to other disciplines, I'd say software development man-hours usually involve a significantly higher ratio of "novel" solutions, since reuse of program logic through libraries is fairly easy. If you are an architect drawing a house, or a lawyer writing a contract text, much (though certainly not all) of what you do is repetition of something you have done a hundred times before. By the time a good programmer has solved the same programming problem twice, he/she has already made a library routine out of it. As long as there are humans developing the software, we can't expect perfect code, not today nor tomorrow.

  13. Re:RMS needs to get over the GPL on LLVM & GCC Compiler Developers To Begin Collaborating · · Score: 2

    Another advantage of keeping involved and contributing back is that you get to influence the direction in which the upstream project goes (if the maintainers aren't too obstinate). And through that you make better use of the work produced by people you don't have to pay. Also, contributing a patch back lets you exploit the quality assurance provided by the project, be it explicit or implicit in the fact that your patch will be used and tested in practice by a lot of more people.

    I'd say it makes business sense to contribute back to BSD projects for anything that isn't the core technology of your company. If I run a hypothetical company that makes, let's say, raytracers for CGI effects, the advantages I have by keeping fixes in a logging framework or networking library to myself are very small. Contributing back gains me more. Those things aren't what my company is supposed to be good at anyway.

    If we would be using a BSD licensed raytracing library, on the other hand, then it would be a different matter. But if you are a company whose business case is developing commercial raytracers, you'd better be far ahead of what's available through BSD licensed software in terms of raytracing, or you should ask yourself if you are in the right market. And if you have that expertise and it is what you use to compete, you would keep it in-house under any circumstances.

    So I'd say (smart) companies contribute back whenever it's something that's outside of their core business, and otherwise not. So GPL or not doesn't really make a difference in regard to that -- it's not going to make a company give away what they use to compete, it only makes more companies stay away from your code. Then again, if that's what someone wants, as a matter of principle, then fair enough, it's their choice and I have nothing to say against it.

    This is called the moral rights of a work, and in many countries it has a different time limit than the commercial rights and cannot be transferred from the original author. I am not sure how it would apply to your jingles example, but I know of one case in Sweden where a film maker successfully sued a TV network for showing his film with added breaks for TV commercials, even though the network had acquired the necessary distribution rights, arguing that they had distorted the creative expression of his film (or something along those lines).

Sure people "are always going to do what feels good", including sharing nude pics of themselves to people they love in the expectation that they are kept private. Why should they be punished for it (by ridicule and shame) instead of (by law) the douche bag who intentionally and maliciously spread them? Yes, it's always going to be some risk having nude pics of you exist somewhere, obviously, but so what? You haven't really answered why you think it is such a good idea to allow revenge porn in the first place.

    No, most laws are not there to protect the weak. Some are, yes, but one of the primary purposes of law is to enable trust between individuals. This is what makes society function. If I own a house and hire carpenters to work on it, I can leave them working in the house while I go out, to a great extent because laws ensure that stealing from me is illegal. You could say that, well, you are a rational adult, and if you leave them there by themselves you can suit yourself if they nab stuff -- it's not society's role to prosecute them for it. And yes, we could build such a society. But it would be a completely dysfunctional one where the overhead for doing any kind of business transactions would be so large that the economy would probably collapse.

    I really don't see what the benefit is of allowing idiots to upload nude pics they have gotten hold of, for everyone to see, with the purpose of revenge and causing humiliation. Why is that ever a good thing? Isn't it much better that men and women can have a reasonable trust (not perfect, but reasonable) in that whatever intimate things they record with their girlfriend or boyfriend won't at some later stage get published on the Internet against their will, backed by laws in the same way my possessions are when I hire carpenters?
