  1. Kilogram is a mass not a weight on US Objects To the Kilogram · · Score: 4, Informative

    Newton is a weight. The summary (and the Fox article) are incorrect, while the NIST article correctly refers to the reference mass.

    No, inductive transfer has been used in a few implanted devices, although supplying the wattage necessary for an LVAD is a challenge. Keeping the coils in place is rather trivial, as these people need to wear accessory belts/vests and external battery packs.

    I know of at least one artificial heart manufacturer that was using the technology.

  3. OS 2.1 on Android vs. iPhone 4 Signal Strength Bars Comparison · · Score: 5, Interesting

    After I got my iPhone 3G the very next software update included a change to the "bar algorithm" that was marketed as "improving user understanding of the signal meter" or somesuch. It was in response to user complaints of low signal strength, and somehow (miraculously) the reception improved... more bars.

    So they're rolling back this change?

    4. Support for soft hypens.

    I was just looking at this problem yesterday. It's amazing that the soft hyphen bug has been open since 1999, and still hasn't been dealt with. But if I read the Bugzilla comments correctly (check out bug #9101) this will be fixed in the next major Gecko release, which will be used in Firefox 3.0. So the seven-year wait is almost over.

    Of course, there's going to be a bit of bump when the capsule hits the atmosphere, and there's also the bit of a trick about getting the thing oriented so the capsule if flung upward...

    You don't need to fling the capsule upwards, you need to fling it horizontally such that it doesn't hit anything. To get into orbit you do not go "up", you go sideways as fast as you can. The advantages of being high up are:

    1. the atmosphere is thinner which means there is less aerodynamic drag on your vehicle, and
    2. there are less things to hit.

    Being "in orbit" is essentially falling without ever hitting the ground.

    Also, Dojo's annoying because it requires you to add non-standard attributes to your HTML in order to identify widgets. For example:

    dojoType? widgetId? Those ain't gonna pass no validator THIS little programmer knows of.

    Dojo's widgets can be defined using a separate namespace, "dojo", so your XHTML will validate. As in: <button dojo:type="Button" dojo:widgetId="helloButton">Hello World!</button>

    I did that when I passed up buying an album because of the copy protection. EMI's customer service apologized for the problem with the CD and told me how to return it for a non-defective copy. Note that I hadn't bought the CD (my entire letter was a "this is why I won't buy any of your music" complaint), and I assume the "non-defective copy" would include the same copy protection I was complaining about.

    Your brain does a good job of filtering out continuous (or anticipated) background noise, including a heartbeat. It's similar to the upside-down world experiments where they have people wear CCD glasses which present an inverted image of the world around them... the brain adjusts for the new reality. (And, in fact, you'd be sending a right-side-up image to the optic nerve, because what it sees is inverted/mirrored. Push your eye in the bottom left; watch black spot appear top right.)

    Either way, these devices are very noisy, even if they don't have mechanical valves (and use porcine valves or polymer valves instead).

    Since you seem to know about these things- Why does it have to be continuous flow? If we can make an artificial heart that runs constantly, why can't we make one that turns on and off once every second or so?

    The continuous flow design is "mechanical engineer friendly" in that cyclic operation causes problems with everything from stress analysis to fluid dynamic analysis. It's overall more complicated.

    That being said... there is evidence that indicates the body needs pulsatile flow from the heart. I've read papers which claim the conducting arteries (those are the larger vessels in the arterial system) degenerate if they don't see pressure waves. There are also people who claim that some of the biorhythms are based on the heartbeat.

    The body is complicated.

    I think the reason people want that is because it indicates a certain level of humility. GWB tries to do the whole "man of the people" thing... this stubbornness makes him look like a cock. Would you accept this sort of behaviour from one of your friends?

    Actually, both Kerry and Nader answer "part one" of the question, which is "when are you allowed to change your mind?" Read the first sentence of the question!

    EVERYBODY ignores "part two" of the question which is "please give one example."

    Frankly I think Kerry's answer to "part one" is decent: when you're wrong, admit it, i.e., change your mind.

    Nader gives the same general answer to "part one" but it's very mean spirited, and used more to attack than state facts. And his answer to "part two" is so laughable I'd have preferred he'd kept his mouth shut. How he saw the light and changed his hot-dog eating ways doesn't matter to me IN THE LEAST.

    So... I rank the responses differently. Kerry wins, because he answered part of the question and not the other. I'll pretend he missed the last sentence. Bush comes in second, because I'll pretend he felt the question was a personal attack. Nader comes last because he turned the question INTO a personal attack, and then indicated that his hot-dog eating was at the same level of decision making as all of the stuff he proceeded to slam Bush for. That's a huge disconnect, IMO. I'd rather he'd have let "part two" slide, like Kerry did.

    No, you idiot. The GPL CANNOT be invalidated like this, because it is not a contract. The GPL (and the MIT/X11/BSD licenses too) basically says this: Copyright law grants me, the author of this work sole distribution rights that I am voluntarily waiving provided you agree to these terms. If you DON'T agree to these terms then you have all rights as granted to you by the law.

    Alright, quit the name-calling and explain to me how, if the GPL was found invalid in court, any GPLed software could be distributed. Copyright reverts to the original owner, and I can't distribute their stuff without permission. "Their stuff" in this case refers to almost everything on my friggin' computer, including the kernel!!!!!

    Ya, I have every right granted to me under copyright law, which is absolutely no right whatsoever. That's the entire point of copyright, and the entire point of copyleft.

    The authors of the software have a right to give me a copy, but SuSE doesn't; they haven't been assigned copyright. What happens to the software SuSE gave me if it turns out the GPL is invalid, and they didn't have a right to distribute it?

    THE GPL IS A LICENSE, NOT A CONTRACT!

    That's totally peripheral to my point. The entire FS foundation is built on a license which had (until recently... see Netfilter post by lfourrier above) never been tested. And yet we (rightfully) expect people to respect the GPL. Imagine the GPL was invalidated... we would end up with a giant stinkin' mess until a new license could be worked out.

    Likewise, EULAs haven't been thoroughly tested either. But arguing they're invalid just because they've never been worked over is like arguing I can violate the GPL simply because it hasn't been vetted. I'm trying to show how the shoe can end up on the other foot. And apparently failing miserably at it. :)
