    Does anyone know if these things are sterile?

    They will probably be sterilized (spayed/neutered) before they are sold. That is becoming standard practice among breeders of pedigreed cats.

    Schematics simply don't exist any more.

    The chips that go into digital radio contain logic that has been synthesized from behavioral models. No one, not even the architect of the chip, ever sees a gate-level schematic or logic diagram.

  4. Re:Refractive index on New Ceramic Lensed Exilim Ex-S100 · · Score: 2, Interesting

    It seems that the properties of a ceramic lens offer only marginal benefits to a camera, particularly one with such a small lens in the first place.

    Reduced weight and greater resistance to scratches would be of great value in eyeglasses. Where can I get Lumicera lenses to put in front of my eyeballs?

  5. Re:"Inspired by Konrad Zuse" on Mechanical Pong · · Score: 1

    Zuse was probably inspired by pinball machines, which appeared earlier in the '30s. Relays and solenoids were being mass produced to meet the demands of telephone companies around the world, and it is only natural that inventors would take advantage of their availability to construct all sorts of clever devices. It is logical that games came before computers because of their mass appeal, which meant that they could be quickly turn a profit for their inventors.

    To say that this game was inspired by Konrad Zuse is to ignore the entire history of electromechanical games.

  6. I Think We're All Bozos on This Bus on RFID Not Just for Kids · · Score: 1

    Have you ever listened to "I Think We're All Bozos on this Bus"? If not, consider it a missing piece of your cultural heritage. It's more relevant (and accurate) today than it was 25 years ago. In Firesign's world, theme park gets freaked out by YOU!

  9. Re:Slightly OT - Human Hamster Wheels & Energy on Hamster-Powered Night Light · · Score: 3, Informative

    On a treadmill, an adult male can probably sustain a power output of about 100W. For humans, bicycles are more efficient than treadmills. I've generated an average power of 200W for 2 hours on a stationary bike and I'm a middle-aged geek, not an athlete.

    People are usually interested in this to figure out their calorie burn rate. Here are the conversions:

    1 dietary calorie = 1000 calories = 4186.8 joules = 4186.8 watt-seconds = 0.001163 kWh

    Human efficiency is 20-25%, so you can calculate that you actually burn 4 or 5 dietary calories for every 4000 J of mechanical energy you produce.

  12. Re:Hmmm... on Disney Launches Fireworks With Compressed Air · · Score: 2, Insightful

    OK, that's a good rationale. I must admit, when I first saw the headline on "quieter fireworks", I thought it was another wrongheaded Left Coast idea.

    However, if the launchers can be quicker to set up, consume less material and be more reusable, that will lower the cost of putting on a display, which leads to bigger and better fireworks for everybody. I'm all for that.

  13. Re:Pretty... on Sun to GPL Project Looking Glass · · Score: 1

    The power of a 3D presentation is useless if it is only used to present a window manager, which is basically a 2D concept.

    The rotating windows are cute, but notice that the user's POV doesn't change. They haven't even attempted to model a space through which the user can move. Workspaces need to become rooms--places with purpose and organization and distinctive style. Humans can manage huge amounts of complexity if it is arranged in a 3D space; that's what humans are supremely adapted to do. Give us an information landscape that is at least as well-suited to our abilities of spatial organization as our homes, offices, buildings and cities.

  14. Re:Not exactly solid linking on Do Music and Language Obey the Same Rules? · · Score: 3, Interesting

    There is a lot of theory in this area that does provide a more solid linking that the article suggests. The research in this area has been going on for a long time and has gone far beyond the ideas mentioned in the article. For anyone seriously interested in the subject, a good place to start is with "A Generative Theory of Tonal Music" by Fred Lerdahl and Ray Jackendoff. Originally published in 1983 and reprinted in 1996, this book has been the foundation for a lot of subsequent work. It's not an easy read, but
    much of it should be comprehensible for those who have experience with computational linguistics and a reasonable familiarity with Western music.

    I would add, however, that one should not confuse the fact that music contains structure that is amenable to many of the same analytical methods as natural languages with the rather vague notions of how it "speaks to us". It doesn't appear that music has symbolic and semantic systems that are anything at all like natural language.

  15. Re:What about art? on Realistic Human Graphics Look Creepy · · Score: 1

    ...humans seem to be capable of creating artificial pictures of themselves. The point, as I see it, is that game developers are just particularly bad at it.

    I agree, but I think they can improve.

    I did RTFA and I think the author articulated a very real problem and immediately reached for the easy (and wrong) conclusion. Rather than backing away from realism and going back to cartoons, 3D modelers need to perfect their craft. The real breakthroughs will come when they rediscover what painters and sculptors knew 400 years ago. I don't think that it's impossible. They certainly shouldn't give up just when they're starting to get close, just because the intermediate results are a bit creepy.

  16. Re:Wow, what a paradigm shift on Looking Into The Power Architecture Future · · Score: 2, Insightful

    I beg to differ. It's relevant to the self-esteem of the average consumer,
    when comparing his purchase to that of his neighbor.

    I find it ironic that MIPS were dropped from most advertising, in part, because
    they were misleading, so manufacturers went back to quoting clock frequency, which
    is even moreso.

    I've helped do it. Occasionally, pins spec'd as "VCC" or "GND" are not power pins at all, they're
    inputs that put the processor into a different configuration. The same chip is sold with different
    part numbers (and at a different price). In some cases, the mode pin is tied off inside the package,
    but in other cases, it's brought out. You would only need to check the impedance to discover it.

  21. Any Better Reviews Out There? on 13 Energy Drinks In 3 Sessions · · Score: 5, Interesting

    It would be good to know exactly how much caffeine is actually in some of these drinks. I'd also like to see some taste panel results or surveys.

    I've found that one or two of these will keep me from falling asleep after a three- or four-hour ride and a hot shower. I don't drink it before the ride, because keeping my heart rate under control is essential to maintaining speed on a long ride. Caffeine will give you tachycardia if you're pushing the edge of the anerobic threshhold.

    Some of these drinks taste really foul. I've found that Red Bull does the job, but it doesn't taste very good. SoBe Adrenalin Rush tastes worse. KMX tastes ok, but doesn't have any kick, as far as I can tell. The best combination of taste and effect that I've found is AMP, but I'd like to hear some other opinions. The article was humorous, but it wasn't informative.
