  1. Re:NG, what happened to you on Felix Baumgartner Prepares for Supersonic Skydive Attempt in New Mexico · · Score: 1

    Did you keep those droplets warmed to 37C? Baumgartner's skin will probably be a lot colder than that, but membranes in his mouth and throat will be kept pretty close to internal body temperature.

  2. People aren't good at estimating risk on To Encourage Biking, Lose the Helmets · · Score: 1

    In general, people aren't good at estimating risk. Most of the time biking is safe, and you don't need a helmet. But if you do crash, you are quite high above a very hard surface, so landing on your head can easily cause a concussion or worse.

    So if you ride carefully and avoid crashes, maybe you don't need a helmet? Well, that's where bad risk estimation comes in. In many years of riding I haven't crashed often, but I was never expecting it: once my front wheel got stuck in a rut, once a stick on the road flipped up into my spokes, once a taxi driver who was looking the wrong way drove into me. My wife has crashed less (she lost control on a patch of loose gravel once), but she got a concussion from it. (She wasn't wearing a helmet; I think it would have made a difference.)

    I don't think people should be forced to wear helmets, but I think they're taking stupid risks if they don't. Brain injuries take a long time to heal, if they ever do.

  3. Re:How high can it shoot? on The US Navy's Railgun Program · · Score: 0

    You just don't have enough imagination. If you want to put a projectile into orbit from your imaginary railgun, and can't get it high enough for a gravitational slingshot, just *hit* something (another projectile, a satellite, whatever) in such a way that it bounces off
    in the right direction, or the two things stick together.

    No need for a rocket motor, just careful aiming (and a bouncy or sticky, but not very brittle, projectile).

  4. Re:How high can it shoot? on The US Navy's Railgun Program · · Score: 1

    Pretty high, but not into orbit. Orbital velocity is about Mach 23, and escape velocity is about Mach 33. The imaginary railgun only goes to Mach 10.

  5. Re:Rainbow tables on Hotmail No Longer Accepts Long Passwords, Shortens Them For You · · Score: 1

    Yes, they probably did that from the outset. Other posters have said that's exactly what they did; I haven't checked, but it seems like a credible explanation, and doesn't require cleartext passwords to be stored.

    (The only way would be if they had anticipated such a change way back when the hashes were generated, and they generated a 16 character hash along side a full hash, and so now they are just switching which hash they use.)

    That's not the only way. Another way would be that they silently dropped all characters after the 16th, then formed a hash from what was left.

  7. The journal gives a better headline on Scientists Say Organic Food May Not Be Healthier For You · · Score: 4, Informative

    If you go to the Annals of Internal Medicine web page, they advertise the paper with this headline: "Are Organic Foods Healthier? There is little evidence that organic food is more nutritious but it may have fewer pesticides and antibiotic-resistant bacteria."

    This seems like a much fairer evaluation of the results than the NPR or Slashdot headline.

    At least if you're paying Microsoft for the service, they're obliged to fix it.

    Can you show me where they guarantee to fix bugs? All I've ever seen is a denial of liability. They'll say it performs "substantially as advertised" for 90 days, but no more than that.

    On the other hand, most open source software explicitly denies all warranty, but is still more responsive to bug reports.

  13. Re:Corporate tax... not sure. on Taxes Lead Angry Birds Maker Rovio To Consider Move To Ireland · · Score: 2

    Corporations have many of the same rights as citizens. Why shouldn't they have some of the obligations?

    You say your government does nothing of value with the taxes it collects. Do you ever use the health care system, the legal system, the education system or the transportation system? Those are paid for mostly by taxes at various levels. Most research in Canada is funded from taxes, because the corporations won't. The government does a lot of things with my money that I don't like, but in the main, they are reasonably well spent.

  14. Re:More than once on Venus To Transit the Sun In June, Not Again Until 2117 · · Score: 1

    I've seen a reduced aperture used to view the moon, but I've never seen that done for viewing the sun. It would have to be a really small hole (a lot smaller than your iris; you can't look directly at the sun, can you?), and you'd lose all your resolution.

    Maybe you're thinking of a pinhole camera, where you use the pinhole instead of a telescope to project a solar image.

  18. Re:Misleading headline on Open Source Project Licenses Trending Toward Open Rather than Free · · Score: 1

    You can choose to change your license on new code. However the code that is already release will remain GPL and can continue under someone else's leadership.

    Sure, someone could continue a GPL fork of what has already been released. But I've got no obligation to continue to distribute source code. I'm sure there are lots of small projects where *nobody* has the source but the original author, and in those cases, nobody would be able to fork it without the author's cooperation.

    That's why this "survey" is so useless: they say 56% of projects, but don't define what constitutes a project. I bet most of them have no users at all.

  19. Re:Misleading headline on Open Source Project Licenses Trending Toward Open Rather than Free · · Score: 5, Informative

    If you're speaking "technically", you're wrong. If I release a project under GPL, I can release it under any other license I like later.

    The only time I am tied to GPL is if I choose to incorporate someone else's work into my project, and they don't want to change licenses.

    So on a big project with lots of copyright holders, it is nearly impossible to switch to a more permissive license, but that's because it's so hard to get a big group of people to agree, not because the GPL doesn't allow it.

  22. Re:Community on Open Source Advocates' Attitudes Toward Profit · · Score: 1

    Your analogy is wrong too. You say it's like

    the facility owners of the homeless shelter telling the volunteers that they're now going to be a motel, and thank them for all their help making it a great facility, but buh-bye.

    But if the project was open source, the code at the time of the split is still available, and anyone else could take over. So it's more like the facility owners decide to retire from running the shelter, and offer it to anyone else to take over. The former owners want to go into a for-profit business, but there's nothing to stop you from taking over the work they used to do.

    Users of open source software owe the developers a lot more than the developers owe them.

  23. Re:Blackjack is the only game I play on Blackjack Player Breaks the Bank At Atlantic City · · Score: 1

    It isn't hard to put together a scheme that wins more than 50% of the time, if the losses are bigger than the wins. The standard doubling up scheme does that:

    Bet $1 at even odds the first time, and keep doubling your bet until you win, run out of money, or hit the maximum bet, then quit. If each bet has a 45% chance of winning, and you're allowed to play 5 times (i.e. the max bet is $16), you'll come out ahead 19 times out of 20.

    The problem is that when you come out ahead, you're ahead by $1; when you lose, you lose $31.
