  2. Re:Kiss HTDV goodbye on Broadcasters Accuse Telecom Companies of Hoarding Spectrum · · Score: 3, Interesting

    It is fairly hard to make a public-interest argument in favor of using scarce(note to spread spectrum and other tech-trick enthusiasts: yes, how limited it is strongly depends on how smart you are about it; but it is finite) spectrum for high-bandwidth broadcasts.

    There are the "public information dissemination"/"cultural goods" arguments, which are reasonably strong; but also amply satisfied by even AM quality voice and smeary NTSC quality video. More video bandwidth is certainly better; but that "better" is simply an aesthetic improvement, not a matter of any significant interest(especially in a world where the bandwidth of blu-ray+USPS is so damn high. There is a value in people being able to get current news/political events/hazard warnings in real time; which is a broadcast specialty; but there is no need to allocate enough spectrum so that they can count the pores on senator scumweasel's nose. For ~$12, you can get 50GB video entertainment chunks mailed to your door, not to mention consoles and HTPCs and all the other non-broadcast uses of HDTVs)

    That said, I'm really not an enthusiast of the "sell it all to Verizon, Ma Bell knows best." theory of spectrum allocation. I'd prefer to see a much stronger support of un or minimally licenced data-transmission spectrum, along the lines of wifi; but with spectrum that doesn't totally blow. Even laboring under those restrictions, wifi has been an amazing success, and the possibilities of future minimal-licensing wireless are really much more compelling than "another bunch of TV channels" or "200mb/s TO YOUR CELLPHONE* *Capped at 5GB/month, overage $10/GB, you're damn right other terms and restrictions apply, see 2,000 pages of fine print for details.*"

    It's more or less undeniable that we are going to run out of low-hanging fruit as time goes on(it is, after all, entirely reasonable to take advantage of the most accessible potential improvements to your technology, which necessarily leaves you with improved technology and a harder set of future improvements). Just imagine how disappointed somebody upgrading from a vacuum tube based system to an IC based one would be with the rate of progress at any point from then on...

    The part where I think Kaku goes right off the deep end is where he predicts dire catastrophe because of this. The notion that there may be certain hard limits, based on the increasingly unhelpful properties of matter as you start working with less of it, isn't a secret to anybody, even if we don't know precisely where the hard limit is waiting... Even when we hit it, all our existing chips will still work, and transistors will still be crazy cheap. They just won't keep reliably getting cheaper at high speed.

    To go with a historical analogy, Kaku makes me imagine somebody during the industrial revolution, standing on a soapbox and shouting about how "Our steam engines cannot keep improving forever, no matter how clever our machinists and engineers, we will hit the Carnot limit for heat engines, and all progress must cease! Disaster! Calamity!" In terms of the physics, that isn't wrong: thermodynamics does place certain hard limits on the efficiency of ideal heat engines. You can tighten your cylinder tolerances and lubricate away friction and insulate all you like; but that's the limit. However, it doesn't follow that no longer being able to expect next year's heat engines to be more efficient than last year's means doom. It just means that you won't keep getting nicer heat engines automatically...

    Among other factors, the Concorde was arguably positioned outside the limits of speed / air-resistance economics... If you look at more recent work in aircraft design, the two big trends are large, high-efficiency, slightly subsonic designs that allow airlines to link major hubs at low cost per unit weight and/or floor space(freeing them to trade off between selling large numbers of cattle-class tickets, or smaller numbers of 'you get your own damn living room' class tickets, or a combination, with minor interior remodeling) and relatively cheap smaller models to cover the peripheral airports that bring travellers to the major hubs at fairly low cost.

    The Concorde is a bit of a white elephant because, due to the engineering constraints of supersonic flight, it is actually pretty horrid inside(only four seats wide, limited overhead compartments, etc.) but extremely expensive. Particularly with the advances in mobile computing, cellular/satellite data links, and so forth(and, on the downside, advances in being hassled by rentacops at the airport), it is kind of a hard sell even for the money-is-no-object crowd for which it is the best economic fit. The big subsonic airliners can offer you a fairly roomy and comfortable environment, with electricity and bandwidth, and a reclining chair and such, for less than the Concorde can offer a faster; but rather more spartan, trip. Unless we see a fairly fundamental shakeup in what business travelers want, it is difficult to imagine enough of them choosing fast-and-spartan to bring the economies of scale even remotely within reach of the "it's huge, and fuel efficient, and you can swiftly adjust the ratio between luxury class and cattle class without changing airframes" designs that are preferred today.

    While the envelope has continued to be pushed in the less cost-constrained military designs, we've actually seen some orphan high-speed exotics there as well. The SR-71, another sweet looking but hugely expensive high speed design, is out of a job now that a mixture of satellites and long-loiter robotic cheapies are doing surveillance jobs. It would appear that very high speed atmospheric operation, while cool and possible, often isn't worth the trouble.

  8. Re:On vacuum tubes. on Michio Kaku's Dark Prediction For the End of Moore's Law · · Score: 1

    I agree that the doomtastic prophecies seem rather overblown. If nothing else, the fact that it is (comparatively) easy to make predictions about the endpoint of Moore's law, and the approximate performance thereof, makes being taken by surprise harder. And surprise, not limitations in themselves, is where complex systems really tend to bite it. We know how large atoms are, we have predictions of varying pessimism regarding how many you need to make a transistor that will actually work, and work often enough that you can fabricate chips out of them in some economically viable way. From there, you can calculate the approximate transistor density of the various endpoints. If those crazy kids in engineering happen to out-perform you, great. If not, that sucks; but you still know where you are.

    Then there is the fact that only certain applications need ever more power. The scientific computing and simulations people are certainly happy to soak up every cycle you can afford to throw at them; but many other applications reach diminishing returns at much lower levels. The end of Moore's law won't suddenly make those stop working, we just won't be able to shrug and say "eh, it'll be twice as fast and half the cost next year." anymore. If our economy is on such a razor's edge that that is going to throw us into global chaos, we have broader issues...

    I'm not quite sure where you are projecting from; but my comment was a quite narrowly focused observation that childhood bullying was of the same 1st amendment salience as late-night disturbance of the peace: that is, extraordinarily minimal and well below the level of concern.

    Now, that said, I have approximately zero confidence that school admin will be able to do much of anything based on this new mandate. In my school experience, adult authority figures were, without exception, useless or worse in dealing with bullies. I doubt that they've improved too much, and now their mandate is supposed to extend to the internet? Good luck with that one, guys.

    However, I really must take exception to your tedious argument-from-cliche and your extraordinarily optimistic take on the level of persistence shown by bullies. Again, in my(admittedly anecdotal) experience, such behavior is far from transient and is, in fact, extremely stable over the 4 or so year horizon that a given school has to deal with. Bullies are sadistic animals and they do not respond to being ignored, or appeals to reason. Violence, however, surgically but intensely applied, had a 100% success rate. You have to speak to them in a language that they understand.

    If Ubisoft can do a slick, mass-market version(even if only for a single instrument, at present) they'll likely have something with a lot more polish and shiny bits, as well as an engine that could be adapted to other instruments if the market so demands. That will likely put nontrivial pressure on the SmartMusic guys...
