    Gatto said something in one of his writings IIRC to the effect of, "So you take 25-35 four or five year old children, throw them together in an environment with minimal meaningful adult supervision (especially at recess), and you expect them to form any sort of healthy society? Why on Earth would you get anything but a horribly disfunctional, destructive, fundamentally childish society?"

    Which matches my experience pretty well. It is this society the non-homeschoolers are claiming is so wonderful that it is somehow vital that we all grow up in it, on which I call "Bullshit". It is so easy to graft higher levels of society down on children that just about the only way to raise the uncivilized hellions that we do is to segregate them the way we do.

    I've talked to several homeschooled children, well socialized, and had actual conversations with them, despite a ten-year gap. I've only rarely had that kind of luck with public-schooled children... sometimes, certainly, but a lot of them are so stuck in their school culture they are unreachable.

    The home schoolers are almost immune to television culture manipulation, too, from what I've seen. Tied to a real, adult culture (suitable adjusted for children), instead of an isolated peer culture, leaves them a lot more able to think for themselves; I'd bet even the religiously raised ones do better in the "thinking for themselves" department.

    This is one of those books you have to let percolate a bit before passing (negative) judgement against it; I first read the book just as I was getting my Master's degree and it is hard to come to grips with the idea of just how much of your life has been wasted by the system. A lot of you are still in school and the cognitive dissonance can still be bad for you.

    And I was even one of those who would attack the schools on other grounds, mind; I was open to the idea it was flawed, hell, I knew it was flawed, but just how deeply and how deliberately sent me into shock.

    Give it a try; more of my opinion in the above link, though I won't trouble Slashdot with it. Gatto really puts his case together well.

    Also, I observe there are a lot of Slashdotters who reflexively assume home schooling is some sort of evil. Make sure you first satisfy yourself that the institutional schooling we now have is not itself a form of evil, perhaps even worse. Having read both sides of both issues, at this point I consider not home schooling borderline child abuse. Most of the homeschooling flaws pointed out by people, such as the ever popular (and unfounded in my experience) "lack of socialization" is correctable, with parental effort. The flaws in institutional schooling are not; indeed, they are assumed "beyond reproach". What amazes me about the human spirit is how many escape the system as I did without a crushed spirit, not how well it works.

    Well, maybe you decide you understand what's going on, and therefore that particular variable can't possibly be important, or you overlook it, or the variable isn't reported correctly etc.

    But when they go to analyse it, they will be completely baffled. They'll probably be able to peg the chips as where the magic happens, and they might be able to see the traces on the chips, but their best chemical analysis of the day will tell them that the chips are pure silicon. Which will most likely result in some highly fallacious theories about the potential properties of pure silicon crystals... which will only be put to rest hundreds of years later when someone finally replicates doped-silicon transistors.

    It has always been a viable theory that cold fusion is possible, that P&F were onto something, but that we didn't have the technology to know what to look for, or if we did have the tech, we had no clue what to apply to the problem. Nano-scale properties of the metals could have been in play, and people attempting to replicate the experiment may have been nowhere near in the ways that matter.

    The burden of proof remains on those who claim to have it, and I remain skeptical. But I'm the real kind of skeptical, the "show me the evidence and I'll believe", not the "I tried your experiment once and it failed, now I will publically mock you, make sure you never work in science ever again, and never again even consider trying another experiment of this type" kind. I have always been uncomfortable with the deeply unscientific way the cold fusion incident was handled, and I don't mean by P&F. Scientists need to be able to have a fluke in their experiments that may not be immediately replicable without running them out of town on a rail.

    I don't think it's fair to place this solely on music. There are many things far louder than your average concert.

    While we'd have to wait for the science to be sure, I think attributing it on the music is fair. Your other loud sounds are noisy, in the spectrum sense. Only music (that I can plausibly think of as a routine occurance) will blast all the energy into a relatively tight frequency distribution. It is very plausible that this could have an effect.

    While the global volume of a drag racer and a loud rock concert maybe the same, I would imagine that the rock concert could have a lot more energy right at, say, 30Hz, and if you're an unlucky smoker who happens to have a resonance frequency in your lungs there, well, that could be a problem.

    (Remember, folks, Star Trek to the contrary most things do not have a strong resonance frequency, especially soft things. However, as you pump more and more energy into some object, even a very weak resonance that would normally never be noticed could be enough to tip you over the edge. Your lungs won't have any strong resonance frequency that someone could play to "tear your lungs apart" at a really low volume level, but if you've already compromised them by smoking you might just rip something in there. Eventually, loud sound starts to look like an explosion from an instantaneous perspective...)

    Yes you do. Otherwise you might just as well say "it is decided by the flip of this coin", without specifying whether heads or tails means it will halt.

    No he doesn't; Welpa explicitly said one program, and he is right in that case. The Halting Problem is that you can't create a program that does it in all cases. Any finite number of cases can be solved by a lookup table. Populating it may take some work in the real world but in the math world we can just assert its existance confidently.

    Some people then take this to mean since computers are finite, the halting problem is not an issue in real life. These people miss that the lookup table will be exponentially larger then the machine the table works for, which means it is still a real problem, since the problem is always larger than the machine, for any size machine.

    The point of the article completely went over your head.

    No, it didn't. You are magically invoking parrallelism, and hoping the magic of the brain lies there, rather than in how the nueral networks work. Which betrays a serious lack of comprehension of how the brain works, and as a result, your fancy scheme falls down from axiom one.

    If you pursue this, I personally guarentee you will have more "algorithm-based" problems than those of us in the mainstream.

    I understand how your scheme works. I've seen other graphical languages that differ primarily by the fact they will solve real-world problems better.

    Like I said, wake me when you have a better solution to a problem. With your comprehension of biology and computer science, I'm not holding my breath. For instance, this rather breathtaking claim:

    In COSA, there is only one algorithm... at the application development level, it is all synchronous software objects.

    Yes, I saw that, but your objects are algorithmic. I saw AND gates and OR gates and other gates, built up into more complicated objects. Welcome to the world of algorithms. That is not how the brain works. This is why I said that you may have hidden the algorithms from yourself, but I still see them, plain as day. Parallel graphical languages have been done, and they weren't a magical path to bug-free programming.

    Put another way, your objects trivially serialize into LISP programs, with a small handful of custom functions.

    BTW, I am very open to alternative formulations that solve fundamental problems in new ways, so you really shouldn't discount this as some close-minded person desperately clinging to what they know. I know software sucks. However, I see every reason to believe that your scheme will be a massive net negative. You've created another scheme that avoids problems as long as you stick to the simple samples but won't scale into even the simplest real-world problem, which is the same problem all of the previous general-purpose graphical languages fell into. You see there's a problem, like the rest of us, but you have only a vague and fuzzy sense of what it is, and as a result your solution doesn't even begin to make progress.

    Worse; the sound is dissapating into the environment at your belt buckle, but will be directed into your ear if you have it at your ear when it goes off. You can probably tack on another 3-10 dB for that, depending on the phone's construction. (Wide range there because I don't know the numbers, just the effect; for that matter it may come out over 10, I'm just not confident about it.)

    The inverse square law is for a perfectly spherical emitter in an obstacle-free environment (a sea of air), in reality it can be a bad over- or under-estimate, depending on whether the sound is being directed toward or away from you. This is one of those cases where it an under-estimate, possibly a very bad one, because the sound is fairly directional by design, and when held to your ear, it is directed right into it.

    As the sound gets more and more directional, the drop-off approaches 0; you can never reach that, but if you've heard about those ultra-sound based speakers that use non-linearity in the air to create audible sound, one of several reasons they are cool is their ability to be highly directional (higher frequencies can be more directional), so you can beam sound across a football field if you want, since the sound's directionality borrows the characteristics of the ultra-sonic frequencies.
