  1. Yes, a paltry 5% on Microsoft Dumping License Fees For Windows Phone? · · Score: 1

    Yes, a paltry 5% of the one billion cell phones sold in 2013.

    5% of 1B...let's see...carry the knot...I make it a truly pathetic 50,000,000 units sold. Insignificant indeed. Especially when you compare it to the gargantuan sales of personal computers in 2013 (82M units). No comparison at all.

    My last three laptops cost about $300 each. Last cell phone (Nexus 5) cost $400. No comparison there either.

  2. Nonsense on Men And Women Think Women Are Bad At Basic Math · · Score: 1

    Good singers very much know how to sing, and how to teach. I have received instruction from a number of them.

    My father taught, and was very good at math. I also teach, and used to teach math to my fellow students in high school.

    Being good at math is like being a good programmer -- iterative process, more than one way of doing things, things build on other things. Not something that everyone is good at, but not something that "you can't teach because you are good at it".

  5. Re:A Natural Consequence on Einstein's Lost Model of the Universe Discovered 'Hiding In Plain Sight' · · Score: 1

    Wiki: "Theoretical calculations showed that a static universe was impossible under general relativity". So I'm not so sure about that remark either.

    Later on that same wiki page: "Problems with the steady-state theory began to emerge in the late 1960s, when observations apparently supported the idea that the universe was in fact changing: quasars and radio galaxies were found only at large distances (therefore could have existed only in the distant past), not in closer galaxies. Whereas the Big Bang theory predicted as much, the Steady State theory predicted that such objects would be found throughout the universe, including close to our own galaxy."

  6. No on Can Science Ever Be "Settled?" · · Score: 1

    No, it is how we stretch ourselves.

    Every single person here learns word(s)...from everywhere, including this site. Are we supposed to jam them in a can under the sink?

    Only a jerk would complain about someone trying to use a new word, a word they might not be intimately familiar with.

    Someone used "dimensionful" and I proceeded to use it a bunch of times (in a physics paper) right after I read it.

  7. The modern teaching technique on Mathematicians Are Chronically Lost and Confused · · Score: 1

    "Guess and go" -- the modern teaching technique. Not in a good way. This is seriously what they are teaching kids today.

    I'm not sure why the word "teaching" is still used. That movie title comes to mind: "I Can Do Bad All by Myself" -- interesting that both movies with that title on IMDB are rated in the 3's.

    They don't teach phonetics. Kids in middle school don't even know how to do long division. WTF.

    FWIW, I am not big at being able to derive things. My idea of studying is to work through the problems. If I don't understand a group of them, THEN I dig back into the theory.

  8. Sports on Feds Now Oppose Aereo, Rejecting Cloud Apocalypse Argument · · Score: 1

    What about sports? Worth making "an appointment", to me.

    It is funny how the /. crowd will talk about how live music is where it is at. Forget about CDs, perform and sell T-shirts.
    But when it comes to sports, we are supposed to...watch it on DVD? Or via some LoQ YouTube put out at some random time in the future?

    Where is the consistency?

    Plus, ever try to watch sports when you know the result? Or try to avoid learning the result for a day while you wait for it to be put up online?

    Also, as soon as you try to replace TV with something else, there are always holes. Trying to replace DVDs with BluRay and there will be holes in your library...forever.

    These things can co-exist. They do for me. But I can understand if some can't afford $50/month for Comcast TV. Just don't make it seem like there is only one choice.

  9. Same experience on Comcast Turning Chicago Homes Into Xfinity Hotspots · · Score: 1

    Bunch of calls. I had tech questions about their product. They had no answers. Gave me the run around. One person even hung up on me.

    My question was whether I could turn off the wifi permanently, or would it always default on after a reboot. Never got an answer.

    The other question I have is the wireless radiation level. My new NetGear puts out 22,000 microwatts per meter squared.

    Anyone taken a meter to their Comcast router? With multiple bands I bet it is also in the 20,000 range...

  10. Except Costco on RadioShack To Close 1,100 Stores · · Score: 1

    Except Costco. A Costco is flat-out cheaper. Almost every time, and especially on the core products we all buy every week. Combine that with the convenience and it is very hard to beat them. I no longer try. If they have it, end of story. Otherwise, start checking at other stores.

  11. How about the weird sell on RadioShack To Close 1,100 Stores · · Score: 1

    Speaking of HD, and Lowes. I chose Lowes because it was more convenient -- I went past it every day -- and it had the item I regularly bought.

    Anyway, I went for the Lowes credit card, and save on each purchase. Whoop.

    The totally bizarre part is every time I am at the cashier, they always ask if I have a "My Lowes" card, or some such thing. They never give me a few features and benefits -- just confuse the snot out of me.

    If I already have the discount CC, why would I want some other probably spamalishus card?

    Other than that, no other weirdness in the whole story. No random selling. Just helpful staff (as I have found at HD as well).

    ...I think they blew it on the discount CC. Should have gone the Target route of a "custom in-house finance" card, so that they track everything (I'm sure) in exchange for that 5% discount. Also, Red card shoppers warp through the checkout. Smart. I don't care for Target in many ways, but they also show they know what they are doing in many others.

  12. Exactly right on Physicists Test Symmetry Principle With an Antimatter Beam · · Score: 1

    Others have challenged you on this, but those same techies would agree that old tech never dies, it just co-exists alongside new tech. The same happens in physics.

    What amazes me the most is how people will go off and try to prove some conjecture of some theory...when the larger theory has massive flaws. It smacks of graduate students and research dollars.

    At least part of the cause, IMO, is that simple things are small, and complex broken things are big. And there is a lot of time to fill in a 45 minute "hour" of televsion. Or a 300 page book. So trotting out the old theories is what almost every physicist does. You do that enough, and you will start to smell like a museum but by then it is too late to change. The tar pit has you in its grasp.

    My new theory of physics.

    Well, the Smart meters call home, so they could be like a cell tower, no? And it is almost in your house. So the reception should be excellent.

  18. I'm curious on Ford Dumping Windows For QNX In New Vehicles · · Score: 1

    I'm curious if there is a standard or definition of what real-time is. Seems to me this is a moving target -- I imagine today's RTOS are much better than ten years, that are much better than twenty years ago, etc.

    I can see that you don't want major lags, but is this defined with a percentage? Or is there just a relative comparison -- this OS is better than that one?

    For me personally I would want hard numbers -- "This OS has a guaranteed response time of xx msec." Is that done?

  21. Wiki defn. on Supernova Secrets Seen In X-Rays · · Score: 1
    Wiki:

    The distinction between X-rays and gamma rays has changed in recent decades. Originally, the electromagnetic radiation emitted by X-ray tubes almost invariably had a longer wavelength than the radiation (gamma rays) emitted by radioactive nuclei. Older literature distinguished between X- and gamma radiation on the basis of wavelength, with radiation shorter than some arbitrary wavelength, such as 10â'11 m, defined as gamma rays. However, with artificial sources now able to duplicate any electromagnetic radiation that originates in the nucleus, as well as far higher energies, the wavelengths characteristic of radioactive gamma ray sources vs. other types, now completely overlap. Thus, gamma rays are now usually distinguished by their origin: X-rays are emitted by definition by electrons outside the nucleus, while gamma rays are emitted by the nucleus.

  23. Re:This explains quantum physics on Mathematician: Is Our Universe a Simulation? · · Score: 1

    There are thing smallers/shorter than [the Planck length]

    What I get from wiki is: "According to the generalized uncertainty principle (a concept from speculative models of quantum gravity), the Planck length is, in principle, within a factor of order unity, the shortest measurable length â" and no improvement in measurement instruments could change that."

    This sounds a lot like "if there is anything smaller, we will never know.

    Care to elaborate on how you know there are things smaller than the Planck length?

  24. Re:Production cost on On the Practicalities of Counterfeit-Proof Physical Bitcoins · · Score: 3, Informative

    The Fed pays for coins in that (1) they don't get free money handed to them and (2) they can't accrue interest on coins in circulation.

    My point, that I recalled from memory slightly incorrectly, apparently, is that coinage is a tiny, incidental business. That all involved want to limit.

    Paper money, on the other hand, is what national debt dreams are made of.
