    True enough, there's certainly a different degree of "like" between dynamic and static in that respect.

    I admit I am an analog person and my digital design classes were a long time ago (in internet years). Sorry if my information is out of date.

    Well a long time ago in Internet years might put that right around the time of the Alpha? It was one chip that I know made heavy use of dynamic logic in order to reach such high frequencies before others did. It seemed to fall out of favor mostly for complexity and manufacturability reasons. And what is compared to that the minor problem that it makes silicon debug harder when you can't down-clock the chip too much because then the dynamic logic stops working. :P

    I also think these small super low power chips are far and away more interesting, and more important to our future lifestyles, than speed demon behemoths.

    Your current multigigahertz processor relies on dynamic logic. Dynamic logic does not work at subthreshold (roughly below 1V). This chip almost certainly uses static logic and will not be as fast as a modern CPU no matter what the voltage.

    Gigahertz speeds are not impossible for static logic, in fact most modern processors are in their vast majority (and perhaps entirety, though I couldn't prove it) static logic, and perform quite a bit of logic in a single clock using static circuits. 45nm transistors are really fast, they don't necessarily need the tricks (and design complexity, and manufacturing risk) of dynamic logic to get to high speeds. Maybe the double-clocked ALUs in the Intel P4 series used it for example, but otherwise static logic rules the day.

    Certainly you're right that it's unlikely that this chip would clock that high regardless of voltage. Static logic likes super-threshold voltages too. :P

    The electrical characteristics of a CPU are somewhat more complicated than those of a resistor. True, but in fact a chip's power does scale with the square of the voltage. At a gross level you can approximate the chip as a certain constant resistance for static power, aka leakage, and as an RC circuit with a given constant for dynamic power, which scales linearly with frequency as well. Nobody actually does that, they just measure the power consumption and know that they the number is proportional to voltage squared and frequency.

    Of course I just knew some jackass was going to use this fact to try to downplay the achievement. Okay, yeah, every computer engineer knows that to reduce power by four you drop the voltage by half, but the trick is actually making this work. That's why not every chip runs on 1E-20 Volts, Mr. Anonymous Idiot.

The fact is that in order for the military to maintain its edge technologically, it needs the broadest possible base of pure and applied sciences, regardless of apparent military use, from which to draw. Climatology, material science, medicine, physics, chemistry, all contribute in critical ways to keeping our military top of the line.

After all, you make more money with monopoly sales and monopoly markup than you do in a competitive market, even if you're the market leader.

    If Microsoft fully supported ODF, then it may happen that a great deal of people who would not consider anything but MS Office today due to requiring Office compatibility would decide that OO does what they need well enough and has the right price. Already many people who don't require perfect MS Office compatibility have made the same decision.

    And if you don't need MS Office, then maybe you don't need MS Windows. The entirety of the Microsoft business model is built upon these two monopolies reinforcing each other by being incompatible with anything else. If either of these monopolies is broken, if software compatibility means that MS Office or MS Windows are merely choices rather than requirements for the majority of people, then MS' days of dominance are over.

    I'm saying, if we decide to go the route of making everyone buy health insurance (as car insurance is mandatory in much of the U.S., for example), I'd consider it acceptable for my taxes to pay that mandatory health insurance cost in some cases. The people that it didn't pay for would buy health insurance as normal.

    Ah, okay. Well that's pretty reasonable, but then again I really don't understand how "mandatory" insurance is going to work anyway -- like there's a huge class of people who can afford health coverage for their families, but just don't want to buy it? From my experience any struggling family has health insurance as one of their #1 things to buy if they can pull in more money. If someone honestly can't afford it, how are they going to comply with the "mandatory" scheme?

    I'm not convinced that approach is better than a socialized system. It's a 'what if?'

    Well I'm unabashedly for a socialized system, but I also think that these half-assed "universal" health care systems are even worse than the current scheme. It just sounds like a way to hand even more money to the insurers, and reduce competition.

    The thing that always sticks with me about socialized medicine (and note, as I say this, that it still may very well be the best available choice) is that to my understanding it doesn't reward preventative measures, and in most implementations the greatest need is always served first. That is to say, if I take great care of my body and am generally in good health but develop a very painful but not life-threatening condition, surgery for me is a lower priority than life-saving lung removal surgery on a lifetime chain smoker with lung cancer.

    Well the first observation I'll make is that in general a government-run program has the opposite problem as a private one with regards to spending: Your private company doesn't want to spend your money on health care, because that means they get to keep it, whereas a government program wants to spend as much as possible because that's how you get more money when budget time rolls around again.

    The second observation I'll make is that as far as using available medical resources goes, it's a greatest-need-first system today, and this is fine with me. The thing is that you're generally waiting just to get a surgeon, and one of my main points is that this need not change because if we eliminate the for-profit middle man, we'll actually be spending more money on actual health care and health care professionals, so at least in theory we could have more doctors and surgeons. To the extent that wait lists are a problem in Canada I believe it is due to them spending far less per-capita on health care.

    So you're unlikely to find yourself wanting for surgeons regardless of your need, in particular because the government is going to be more than happy to hire an extra surgeon and secure more funds in the next round of budgets.

    But how do you create incentives for preventative measures in this system? For a lot of the patients I think this is largely moot, as availability of preventative measures will encourage them to go. It's not like my personal insurance premiums go up if I wait on a problem, my company buys the policy for me so I'm largely sheltered from that. No, I go to the doctor earlier rather than later because I don't have to worry about costs, and I'd rather that they detect the cancer or whatever sooner. It's the people without any health care who are most likely to wait until the problem is acute before going to the doctor.

    From the doctor's end, it's less clear how that works. The only obvious solution is to tie it into the legislation that creates the system, which immediately turns into a byzantine mess as messed up as the current insurance tables.

However we have inserted a for-profit middle man into the picture resulting in only a fraction of that money ending up getting spent on actual treatment.

    Is it really that hard to believe that a socialist system like in the UK can actually be cheaper than the for-profit capitalist system?

    A system in which the public decides to cover the health care expenses of some worthy cases, to my mind, beats the status quo where the public essentially covers everyone by default.

The fact is that the tiger had never before attacked without provocation, and it's nigh inconceivable that it did this time.

    A tiger who has mauled someone before might not even think twice about human prey of this size.

    A tiger who is a man-killer would not think twice about any human prey. Do you have any idea of what kind of prey a tiger can bring down in the wild? The only thing that stops a tiger from being a man-eater is that it doesn't associate humans with prey. But having taken a swipe at a handler does not create a human-food relationship in the tiger. The whole point is that the tiger is reacting to the handler as though they were another tiger who is exerting dominance over them. It's a social relationship, not predator-prey, and thus does not in fact make the tiger more likely to attack other random humans.
