  1. Re: How would this get rid of power cords? on Step Toward Liberating Electronic Devices From Their Power Cords · · Score: 1

    Actually its not - a reasonably high capacity car like the Model S has no significant issues with charge time. A ridiculously small number of people drive over 250 miles in a day, the notion that not supporting them directly is a "major hurdle" is just plain incorrect. The number of people who drive over 250 miles a day who can't take 20 minutes or so every few hours to top up at a Supercharger station is even smaller, but we're already well into statistical insignificance at this point.

    Its akin to claiming that since some people need to tow horse trailers, the small towing capacity of every modern mid-sized sedan is a "significant hurdle" that will prevent their adoption.

    As someone else pointed out, it's even MORE appropriate given what he said in the sentence: “Supercapacitors store ten times less energy than current lithium-ion batteries, but they can last a thousand times longer.". That's a good way to contrast 10 with 1000, and it's said eloquently, making perfect sense to probably 99.9% of the population.

    There are two problems with that theory. First, the storage capacity and the duration aren't actually comparable numbers. Second, if they were, you'd want to be comparing them at a factor of 10,000 - if the original sentence leads you to "contrast 10 with 1000," as you say then its poorly constructed. Contrasting "One tenth with one thousand," or "0.1 with 1,000" written numerically, would actually be the correct goal of the sentence.

    All of that ignores the fact that the storage capacity varies with size but the amount of time does not, so its even more ridiculous to try to compare those numbers in the first place.

    > In that example? "A quarter of a percent", by a long shot.
    So you're saying that "400 times less" is more complex than translating from two languages into "a quarter of a unit normalized to 100", then taking the reciprocal of one quarter and applying it to 100 to give 400?

    Yes, because people use phrases like "a quarter of a percent" all the f'n time, but have to stop and think about what "400 times less" means. Its the same way that I never use the "compact" form of time intervals like bi-weekly and semi-monthly because it takes an order of magnitude less processing power for most normal humans to understand the more lengthy "every two weeks" and "twice a month" phrases instead of figuring out what some rarely used expression means.

  4. Missing the point on I Want a Kindle Killer · · Score: 5, Insightful

    I believe that the Kindle is an excellent device primarily because it does one thing - its an eReader. I don't normally write all over my paper books and have no desire to do so on the Kindle either. Far from a luddite, I've got a ton of technology devices, but sometimes simple task-focussed pieces are better. My paperwhite is easy on the eyes, the battery lasts for a long time, its very lightweight, and I never have to troubleshoot it or wonder why its various components aren't playing well with each other.

    Not every device needs to expand its footprint until all are equal. Want to read on a Fire or an iPad? Feel free. Don't try to turn the regular Kindle into a poor version of one of those.

    That's all well and good, but what rolls off the tongue quicker and is less ambiguous for other numbers? For example, "one three hundred and seventieth", or "three hundred and seventy times less"? The latter is clearly superior.

    In that example? "A quarter of a percent", by a long shot.

    Look, if we don't have to be accurate, then we can use much, much quicker and smoother language. We do, however, and while "three hundred and seventy times less," is easy to say, its hard to think about.

    More to the point the goal of language, especially in a technical setting, is to convey ideas in a the way most likely to be understood by the listener, not they way more convenient to say by the speaker, outside of a very few situations.

    It does that if and only if there are no other iMessage-enabled devices that can read it. One of the things that I enjoy about the feature is that I can use Messages on my laptop if I'm working, and my phone doesn't go bananas either reporting that it got texts or expecting me to deal with a sea of notifications - they're there in the history, but even if my phone is turned off or not on a network (happens a lot on planes that charge per-device for wifi) I can text to/from my laptop and nobody knows any different.

    Figuring out when someone's phone is gone "for good" is a remarkably easy social problem but a very difficult technical one. Making it even easier than it is today for someone to Apple when their phone is gone is the solution, not some terribly complicated heuristics. Of course, that still requires someone to do something, which they'll complain about - but such is life.

    PCs that are as powerful as the most powerful phones are so damn cheap that - since you're probably syncing everything on your phone out to clout storage anyway - you may as well just have a cheap PC permanently bolted to whatever workstation you have your monitor and keyboard on. It doesn't cost very much more, its far more convenient, and it lets you optimize the experience and applications in each case without making compromises.

    The issue with BitCoin isn't the acquisition, its the storage and spending. Giving each student easy access to a university-run "bank" with safe backed-up storage and good access would be a big step in the right direction. Having everywhere in MIT that accepts dollars also accept BitCoin would do far more.

    The reason that the dollar works - that all currency works, really - is that people need it to interact with the government. Make BitCoin the easiest way to interact with MIT (for daily use stuff even) and people will use it, which will force them to acquire it, which will entice more people to take it, etc.

    And yet, simultaneously, is quite different from the "anti-vaccination" position the article claims she has or held. As I said, she's wrong about the science, but that doesn't mean that she's lying about her position.

    When she's on record as saying things like "If you give us a safe vaccine, we'll use it. It shouldn't be polio versus autism." (and she is), to me that's as good as saying, "The current polio vaccine causes autism." Other classic Jenny quotes that don't jibe with her current stance:

    "Without a doubt in my mind, I believe that vaccinations triggered Evan's autism."

    "People are also dying from vaccinations. Evan, my son, died in front of me for two minutes. You ask any mother in the autism community if we'll take the flu, the measles, over autism and day of the week. I think they need to wake up and stop hurting our kids."

    So yeah, she's not anti-vaccine, she just doesn't feel that the current vaccines are safe and that you shouldn't take any that aren't. That's not misrepresenting her position, that's just repeating her words.

    For the subset of kids who suffer the same issues as your son, even assuming they could hit at any time during those first six months, the normal CDC schedule of vaccines at birth, 1, 2, 4 and 6 months means that there's a 2.7% chance of the effect hitting on the day of a vaccine. You mention that the affect was the day after the vaccine, so if we could only the same-day and next-day chances, that's covering 5.4% of the child's life.

    Those are actually pretty good odds, considering that we rarely hear specific timing about kids affected outside of a normal vaccine schedule. I'm very sorry that your child was affected, and as a parent of two myself thoughts like that scare me as well, but I'm not seeing an evidence of causation here.

  25. Incorrect on London's Public Bike Data Can Tell Everyone Where You've Been · · Score: 3, Insightful

    From TFA: "What may surprise you is that this record includes unique customer identifiers, as well as the location and date/time for the start and end of each journey."

    The unique ID? Yeah, maybe that's a problem, likely not that big a deal but also easy enough to get rid of (although if we do that, we lose the ability to track joined journeys, identify frequent vs. infrequent users, &c. But that's not the point here.

    Identifying which bike stations you check a bike out from and return a bike to is very different from identifying your movements across London. Very different indeed. I'd argue that you do have an expectation of privacy when you stop along the way to get a cup of coffee, a bit of nookie, or a gyro. As a public transportation user, though, your checkin and checkout actions are totally different than your route.

    In fact, it'd be damned useful to be able to see and show that you did - or did not - retrieve or return a bike at a particular place and time. Its also useful to be able to tell where that bike went in the future.

You couldn't, however, tell whether or not they liked it, if they read it in the bathtub, or if they let their SO read a page or two along the way.
