  1. Re:non-physical physics on New Clues About the Nature of Dark Energy · · Score: 1

    Planck looked the black body radiation problem and the ultraviolet catastrophe and sent of a postcard claiming that fatal flaw was the assumption that energy was continuous.

    Actually, according to Kuhn (and I tend to agree), Planck actually didn't realize he was making that break from classical physics.

    Planck had worked on the black-body problem for a long time, and only after that time did he cave in to follow Boltzmann's ideas, thinking at the time that the quantization condition was simply a mathematical tool. It took Einstein and Poincare to point out that the use of Boltzmann's technique implied small quantum occupation numbers in the high-frequency portion of the spectrum; i.e. that the Boltzmann approach was actually radically new physics.

    Now, Planck did realize at them time that his introduction of "h" and its failure to be cancelled in the final formula was dramatically new: he was quite proud (justifiably, of course) to have discovered a new fundamental constant. But it took years for the new mechanical implications to become clear, even to him.

    People at the "bottom" have jobs *because* these jobs are part of profitable organizations. Companies that lose money do not provide jobs for long. Nobody owes you a job just because you are a nice guy, or a little guy. You get a job because your labor is being put to use in a profitable way.

    When your community cannot provide a use for your labor, then you should either upgrade your labor or move. That's life. You shouldn't blame some international trade bogeyman that you claim to like except when it hurts you, which seems to be all the time.

    Look at the bright side: at least nobody tried to "ethnically cleanse" you. *That* devastates communities.

    A key concept you are missing is that exporting is the "disadvantage" of international trade. Working to produce goods is not the chief reward in life, being able to *consume* goods is! Other countries sending us stuff we want is the advantage of trade. This country sending out stuff that other countries want is the burden.

    And what "normal cycle" of things are you talking about? International trade is not barter by individuals or individual companies. Just because you personally don't get orders from India doesn't mean that nobody else gets orders from them.

    In fact, to a first approximation, all those U.S. dollars that get sent to India to compensate for software services *have* to come back to the U.S. in exchange for something, because they don't have value elsewhere.

    Like I said, READ ABOUT DAVID RICARDO, who understood these issues much better than you seem to way back in the early 1800s.

    Where are the jobs going to come from?

    From the same place that software jobs came from: new companies developing new technologies to serve new markets.

    Way back around the time of the American revolution, about 90% of the U.S. population was employed in agriculture. Today, the corresponding percentage is something below 5%. My god, all those farmers losing jobs! How could you possibly replace all those farmers?

    The answer is that the farmers became immeasurably more productive (actually, there are still too much farming in America due to wasteful subsidies and trade barriers) while the rest of the population found some other job due to this thing called the Industrial Revolution.

    Does anyone think the U.S. has some huge shortage of farming jobs? Someday, we'll feel the same way about tool-and-die makers.

    If I invented some "magic software machine" that worked in response to e-mail and voice commands to produce software according to specification for a small material cost, then that would be a tremendous boost to productivity. I don't have to spend time and effort coding myself, I just have to work on the specs, and the magic software machine writes and tests it for me.

    Given how much Slashdot can gush over the latest gcc release or Java IDE advancement, you'd think people would recognize this kind of machine as a tremendously powerful tool for eliminating grunt work and speeding development.

    Yet, because the "magic software machine" is actually a bunch of Indian programmers at the other end of the phone/e-mail connection, this is somehow a terrible and destructive thing.

    There isn't some limited amount of "work to be done" which has to be divided among workers. Adding workers to the economy does not reduce the amount of work available for each worker. Instead, it expands the amount that can be produced.

    Your economic thinking is about 250 years out of date, in addition to being wrong. Please download the David Ricardo patch to correct this bug.

    Economics and international trade are most definitely NOT a zero sum game. Importing services from India does not directly impoverish the United States. In fact, it allows the United States to produce more by deploying its labor in *relatively* more efficient ways. Your error is one of composition: simply because one programmer in the U.S. is displaced does not mean that there is a net loss in economic welfare in the U.S.

    Trade barriers hurt the general economy while avoiding dislocation of a very visible but small sector of the economy. Nonetheless, the net impact is NEGATIVE for both the importer and exporter. Trade barriers REDUCE the total amount of economic output that can be generated by the economy. They keep the pie small, while the slice that represents the protected sector stays relatively large.

    If instead, we dropped barriers and redeployed our labor and capital according to the freed market, the total output of the two economies combined will increase. Redeployment is painful, but it is more painful the longer it is delayed. Evidently, too many people in the U.S. are working in jobs that can be outsourced, and not enough people in India are working at those jobs. The people in the U.S. need to find other ways to employ their labor where the rewards are higher. Just like they went into software because they could get jobs there in the past.

    The world is a dynamic place. Trade barriers make things stay the same for a little longer, but only because they impede economic growth.

    Yes, but of course they are flawed. Wolfram fails to present anything *better* in the sense of leading to results.

    CA can generate pretty and "surprisingly" complex patterns. In fact, and this is the one real advance, which isn't *new* in ANKOS, just quoted, you can prove that at least one 1-D CA nearest-neighbor rule can support Turing-complete computing. But only if you found the particular rule in advance by a brute-force search.

    The universe is fully of pretty and "surprisingly" complex patterns. That doesn't mean that a CA can be constructed to explain them, or even if one could, that the CA actually "explains" anything, in the sense of telling us something we didn't already know.

    There isn't any apparent way to make *progress* on any physical problem by using CA ideas. Having to do an exhaustive search to identify "complex" behavior in a 1-D CA means that there isn't yet any a priori method to determine which CA have a potentially interesting property, and which to reject. In which case Wolfram's "program" for future scientific progress is a mind-bendingly *huge* and mindless task, which will, just possibly, provide a CA formula which simulates the universe.

    How are you supposed to identify that CA, however, if you don't *already* know what kind of physics that the CA is supposed to simulate? It's pretty easy to solve a problem even by an inefficient technique when you know what the answer should be. But also unnecessary. And not new.

    SMP hardly "blew away" the competition. It was superior in some ways, but much worse in others. It could not use exact ratios, for instance.

    As far as Mathematica goes, although implemented in C, the language attempts to simulate a pseudo-Lisp, and fails terribly. It absolutely reeks of someone who saw Lisp, comprehended it in an only superficial way, then thought they could do better. When you try to actually use it as a Lisp, its defects (e.g. its special treatement of the "head" of the expression, including the bizzare nature of its pseudo-APPLY) make it impossible.

    Another classic flaw of Mathematica is its idiosyncratic approach to "precision." Yes, it has some advantages in toy demonstrations, but still has big gaping holes just like regular old floating-point.

    It is an important part of the marketing of any experiment to give a compelling, easily understandable civilian and/or military goal which relates to the research being proposed. Marketing is an important part of scientific research, because it leads to funding.

    1) what do you want to achieve
    2) what makes you think you have any way of compelling these alleged violators to grant you what you want in number 1?

    These are the basics of entering into any kind of negotiation, but you haven't framed them at all. It so happens that many lawyers are trained to analyze situations of this kind and give advice. Which makes it all the sillier that you want to resolve this without lawyers. "I have a leak in my faucet. I don't know how to fix it, but I don't want to call a plumber." But I digress.

    If you are the typical idealist who reads slashdot and *still* thinks it is a source of useful information, than the answer to question (1) is probably something like "Force them to release the source for their changes." One has to wonder WHY you care. Do you think they've made changes that will truly benefit the community? Or are you just trying to be a pain in the ass to anyone who doesn't want to play by your rules? (This is my ball, and I'm taking it home...)

    Here's a clue: the world ain't fair. People lie, cheat, steal, murder, and do all sorts of awful things to other people who don't deserve it. In the grand scheme of things, is your library really worth fighting an epic battle over? Does it really hurt you to have people take your code without following the GPL? Why don't you just take it as a compliment that someone would find your code worth stealing, and move on? Don't you have anything better to do with your energy?

    After all, even if these guys did steal your code, your code is still available and open to everyone else. The people who didn't get the source from these violators can still get the source from you, off the web. Are the "victims" really any worse off than they were before?

    Anyhow, even *if* you conclude after careful thought, that your answer to (1) is a worthwhile goal, what makes you think you have any leverage to compel the violators to do what you want? After all, releasing the source is a pretty damn easy thing to do. Perhaps they don't understand their obligations, in which case you have to spend your valuable time educating the ignorant. Keep in mind that one has to be pretty willful to be a software engineer and ignorant of the GPL. And most people don't like comparative strangers showing up on their doorstep to "teach." When a Jehovah's Witness shows up on my doorstep wanting to teach me about his faith, I usually just close the door. Folks who do this kind of thing face a lot of disappointment. They are willing to put up with this, because think they are doing it for God, who will reward their suffering. If you worship RMS, perhaps you feel the same way.

    Another possibility is that they don't want to release the code, either because it is risky to their business (no one would pay us if they saw they could get the same thing for free..., or trade secrets, or what not). In which case you have to make your solution more attractive to them. How? What's in it for them? The chance to walk in the righteous path of GNU? What possible ways can you persuade them to change their mind?

    A third possibility is that they are malicious bastards who stole your code just to make you mad. In which case getting yourself in a tizzy will just entertain them more.

    The ideal of Free Software depends on users and writers of software behaving with a certain integrity. It is difficult to force people to behave well unless they are already so inclined.

    Before you go to much effort, be sure that the effort really will pay off.
