  1. Re:yay math on Scientists Create Battery That Charges In Seconds and Lasts For Days (telegraph.co.uk) · · Score: 3, Informative

    Without giving the voltage, those numbers are pretty meaningless. Power = Volts * Amps

    Lightning has a huge power at 2A because it's millions of volts.

    A high-end microprocessor can draw about 100A, but only at a little over 1 volt.

    Your circuit breaker will trip at 15A, but at 120V. That's 1800W. If this capacitor is only charged to about 1.5 V like a typical battery, the 600A would only be 900W.

    Thus, you could easily charge it from a standard outlet. It would require a beefy power supply similar to those in large servers, though. I think that most people would opt for a cheaper power supply that could still charge their phone in a minute or two.

    That issue is simple to deal with, and was solved a century ago.

    The parties in WWI who had battleships that were too precious to loose in combat simply kept them in port for the duration of the war.

  4. Re:Cold, heartless liberal bean counters on Google Search Results Have Liberal Bias, Study Finds (thedenverchannel.com) · · Score: 5, Insightful

    Liberals speak of what they desire *could* be, and very often of how things *should* be. Conservatives focus much more on the cold, hard facts of how things *are*. So much so that it often makes discussions difficult:

    Your describing what conservatives *should* be, not what they are.

    In reality, their "cold hard facts" are often aren't facts at all, but are instead per-conceived postulates. Thus, so much emphasis on "faith" and "principles", objective evidence be damned.

    They are also usually focused less how things *are*, than on how they think things *were*, as interpreted through some distorted rose-colored filter.

    Almost all of the water that goes into beef production is used to grow the corn the cows eat, Einstein. The amount that cows drink is negligible.

    The water used to grow corn ends up evaporating, so sewage treatment is completely irrelevant to this issue.

  14. Re:Black holes orbiting each other? on A Naked Black Hole Is Screaming Through the Universe (gizmodo.com) · · Score: 1

    They're not outside the escape velocity of the sum of the two entire galaxies. So they'll both stay in some orbit within the combined galaxy.

    As they do, they keep encountering smaller star systems, which often get flung off in random directions. The net effect of these random encounters is to slow down both black holes relative to the center of mass of the combined galaxy, similar to friction. As they slow down, they sink towards the center. Eventually, they fall into orbit around each other and continued "friction" causes them to get closer until they merge.

    A trend I've spotted: The desktop version of some websites are now also optimized for mobile.

    There's a little three-stripe menu in the corner, a bunch of icons with no hint about what they might represent, and a list of about 30 words in a huge font. The rest of my 24-inch monitor is filled with white space.

    To get any further information, I need to click icons to dig down and get fed little batches of a few more words or pictures.

  17. It will be trivially easy to disable China's entire army of robot enforcers.

    1. Sneak into the supercomputer base. This is usually possible by jumping onto the back of a delivery truck.

    2. These facilities always have air ducts connecting every room. The ducts are always well lit, and at big enough for two people to crawl through them abreast. Jump into the nearest duct, find the supercomputer, pull out the grate that is just resting on the ceiling, then jump down onto it.

    3. Nobody will be in the room at first, but for excitement, you'll probably be detected about now. You still have plenty of time before they actually arrive, however. Connect whatever gadget you brought (depending on your era, it might be a 5.25" floppy, or a MacBook, or some kind of solid-state crystal). Search through menus as the guards get closer; just as they arrive, find the magic command and destroy the supercomputer's operating system. Bonus points if the hardware starts to explode.

    4. Make your escape. Mission accomplished. The robots all freeze in their tracks just as they were about to execute your comrades.

  18. Saying it's "pure bullshit" is the same as saying human behavior doesn't follow any sorts of discernible patterns and is effectively random.

    Once parameters go outside the bounds of economists' preconceived models, it is effectively random. This has been demonstrated time and again throughout history, with one unforeseen economic panic after another.

    Who was playing up all those scares in the first place anyway? It was those same damned economists that you think have some kind unique of insight into society. As I said, it's all 100% bullshit.

  19. That's wonderful advice, given that the field of economics is pure bullshit. It's the poster boy for a cargo cult science.

    I did spend a little time studying the field of AI back during one of its initial popularity fads. At the time, I quickly concluded that it was also bullshit, and went into other areas.

    However, hardware capabilities and costs have both improved by about six orders of magnitude in the intervening years. By brute force, if nothing else, AI is no longer quite bullshit.

    This stuff isn't science fiction any more. It's in active development.

  20. Machinery that actually gets widely used can usually be operated by a regular person with a modest amount of training.

    What "operators"?. The whole point of AI is to get rid of operators.

    So someone who can't do extremely valuable work can still do enough to get by and live an OK life.

    No, for many people there won't be anything they can do that some machine can't do cheaper. They will have no jobs at all.

  21. provides opportunities for people to move to new places and get new jobs.

    That's the whole issue. In the past, automation displaced some boring jobs. Now it threatens almost every job in existence, other than "wealthy heir".

    Exponential increases in the complexity and capability of the automated machinery will make the old argument of "people have always found new jobs when they are replaced" moot. To be employable, you have to be better than machines at doing something of value, as well as be competitive with other people who can do those tasks. Already, some people don't match those requirements, and in the future, probably most people won't.

    Whether or not *you* think it's too early to worry about the issue now is irrelevant.

Maybe the circuits were just overloaded, but my phone was still useless while it happened.

    They very well may have had *less* uptime than a decent ISP has now. The main difference is that with almost constant use of the internet, you're more likely to notice any outages and get annoyed.
