  1. Different power levels on WikiLeaks Founder 'Free To Leave Sweden' · · Score: 3, Insightful

    Don't trust the government? Smart. Don't trust some guy with a website? Troll.

    I would fix that for you as:

    "Don't trust an organization with $400 billion/year military budget? Smart. Don't trust some guy who's antagonizing the most powerful military organization on earth? Troll."

  3. Re:Put the railgun in orbit on NASA Looks At Railgun-Like Rocket Launcher · · Score: 1

    So wait, you propose that the track and the space craft meet at a delta V of Mach 25?

    Welcome to the world of engineering.

  4. Suse is for business, Ubuntu is for Linux on Shuttleworth Answers Ubuntu Linux's Critics · · Score: 0, Flamebait

    From my experience, the distro that gives less back to the community is Suse.

    I have Suse systems at work and there's always some catch, it never works seamlessly unless you go to a full (paid) Suse solution.

    Ubuntu, OTOH, is nearly transparent, you never feel like you are being obstructed by it. In the worst case, if everything else fails all you need to do is to fall back on some Debian solution that will almost always work in Ubuntu.

    The problem with your idea is that the mouth of the tube should be open, otherwise how would the spacecraft come out? To be open it should need to be in a vacuum, otherwise air would come rushing in. You would need a tube extending all the way to above the atmosphere, let's say a hundred kilometers up.

    An awesome concept, but not simple or cheap.

  6. Re:Put the railgun in orbit on NASA Looks At Railgun-Like Rocket Launcher · · Score: 1

    to 'catch' the track as you say, the space craft must be going faster than it

    No. All they need to do is to be at the same place at the same time.

    The spacecraft is at the top of its trajectory, zero vertical speed, zero horizontal speed. Exactly at the same time the front of the track reaches that same location. A magnetic force catches the spacecraft so it won't fall down. The same magnetic force accelerates the spacecraft horizontally along the track so it will have orbital velocity by the time it reaches the other end.

    The track is bidirectional. It propels spacecraft launched vertically from earth, but it also catches spacecraft coming down. There's a velocity budget to be maintained, it will drop material from orbit to keep its velocity. Where will this material come from? The moon, perhaps. We will have to import mass to the earth as we send mass up.

    Of course, the track must be more massive than the spacecraft it will handle. Version 1.0 will not be able to handle manned spacecraft.

  7. Re:Put the railgun in orbit on NASA Looks At Railgun-Like Rocket Launcher · · Score: 1

    But when you catch the "track" to gain orbital velocity, wouldn't that just decay the track's orbit?

    Sure, but you would also use the track to decelerate spacecraft from orbital velocity to land on earth, which would cause the track to gain velocity.

  8. Speed of light in a simulation on Simulating Galaxies With Supercomputers · · Score: 4, Interesting

    Has anyone else been bothered the fact that energy is quantized?

    Even more significant is that there's an intrinsic speed limitation in a simulation.

    When you simulate a continuous medium by dividing it into small space and time steps, there's a speed "c" that's equal to the space step divided by the time step which cannot be exceeded by anything in the simulation.

  9. Put the railgun in orbit on NASA Looks At Railgun-Like Rocket Launcher · · Score: 2, Insightful

    Sorry, but 10x roller coaster speeds isn't close to Mach 10.

    And even Mach 10 isn't enough, orbital velocity is close to Mach 25. You cannot run at that speed inside the atmosphere, there's no material that could withstand the heat.

    I've seen a much better idea proposed. Put that electric accelerator track in orbit. The energy needed to reach orbital altitude is much less than the energy needed to accelerate to orbital speed.

    One could launch the spacecraft vertically to an interception with the accelerator track, then it would catch the track and get the needed horizontal speed while already outside the atmosphere.

  10. Second Amendment? on Steve Jobs Tries To Sneak Shurikens On a Plane · · Score: 1

    California state law forbids manufacture, sale, possession or import of any shuiken, star, diamond, trefoil or other edged weapon used for throwing. So it's just as well it was confiscated at the airport.

    Let's see:

    "A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed."

    I can't find any exception about shuriken there.

    If it can run Crysis it can simulate galaxies.

  12. Oil industry influence on Canadian Government Muzzling Scientists · · Score: 3, Interesting

    So... have looney Creationists actually gained enough hold on the Canadian government to silence scientific knowledge?

    TFA mentions something about oil sands and mercury pollution in the Athabasca river, so it's most probably work of the oil industry.

    As a bonus, they get silence about floods at the end of the ice age. Any paper about climate is bad for the oil industry, they need ignorance in order to enforce their truth that there is no climate change and if it existed it would not have been caused by CO2 in the atmosphere.

  17. Earth's naturally frozen on Mega-Volcanoes Might Be Detectable On Exoplanets · · Score: 1

    Earth would have remained a frozen snowball 650 million years ago if not for volcanism busting the surface ice apart. Perhaps not coincidentally, the Cambrian Explosion of multi-celled life forms soon followed.

    If it weren't for greenhouse gases, earth would be frozen solid. But there have existed geologic periods when the concentration of greenhouse gases was so high that there was no ice anywhere on earth.

    That goes to show how delicate equilibrium we have, a little bit more or less of those gases is enough to cause wide variations of temperature. Better be cautious.

    Which is a blatant injustice. Once she has agreed to something, she has agreed to it.

    She cannot buy a car and then say "but I didn't know it had fuzzy dice hanging from the rear-view mirror". If she does not want a car with fuzzy dice, she should state it clearly beforehand in a written contract.

    Rape is a serious crime. No one should be convicted of it without proof. Letting the word of the accuser trump the word of the accused inverts all the accepted legal principles.

    If the other person says stop in the middle, you stop. That's a sensible law. It doesn't bring humanity down.

    I don't think sex works exactly that way. How do you stop in the middle of an orgasm?

    The basic premise of sex is that it should only be performed among adults. An adult person would have enough sense to walk out before it becomes an unmanageable situation.

    I don't mean "she had it coming" but if she agreed to having sex with a man and it doesn't turn out exactly as she thought it would, she should have absolutely no right to call it "rape" unless he became physically violent.
