  1. Story on Army Game Proves U.S. Can't Lose · · Score: 1

    You probably have plenty of funny stories, but I'd like to tell you my roommate's. He was in the Reserves and was out on exercise. At one point they were warned to don protective gear. As soon as the simulated chem strike hit, the nearest ref signaled he was dead. Turned out he'd done everything perfect ... except for zipping his fly. Lesson learned: if you're going to die, at least don't let it be from chemicals attacking your nads.

  2. Re:Squished apart on Fastest Spinning Black Hole Ever Found · · Score: 1

    It was explained in a Scientific American article years back. I think they said something about the curvature of space is strong enough that light is bent into an orbit. Since light travels in a straight line, our typical concept of centrifugal force doesn't make sense anymore. Again, I can't remember all the details and what I do remember seems flawed somehow. As for the squish, I'm not a believer that the object inside an event horizon is a point. From the outside, yeah it's a singularity. But the inside could be anything. So why can't it be distorted by rotation? Again, I'm out of my league.

  3. Squished apart on Fastest Spinning Black Hole Ever Found · · Score: 2, Interesting

    If I remember correctly, centrifugal force as we know it actually reverses near a black hole. Pulling inward instead of outward. A rotating black hole may be compressed further by its rotation. Maybe someone familiar with the phenomena can shed more light.

  4. Re:How does it follow the jet? on The Beauty of Fluid Mechanics In Video and Photos · · Score: 3, Informative

    Quick answer is the condensation isn't following the jet. It occurs in air at the edge of the shockwave. As the shockwave passes, the air returns to the same state.

  5. Re:Toast on Warming a Tiny Piece of Mars For Terraforming · · Score: 1

    Just my point: cooling effects are minimal. To warm the air, you have to have much warmer ground. Uncomfortably warm.

    As for the test you reference, they couldn't figure out what was wrong at first. Mars most certainly has wicked dust storms. Then they added sand. Then the dust bounces right up. There's also an electrostatic effect from dust devils (created by localized heating) which is amplified by the thin atmosphere (nice article in Science News about it).

    Of course the dust could reduce heating at ground level solving the first problem, but heating the atmosphere at ground level was the whole point.

    The idea of heating a ring is to warm air before it moves to where you are, allow some flexibility in heating, overheat during the day, give the air some time to drop dust, and maybe create a very minor boost in local air pressure by using the inrush of surrounding air to compress the central pocket of air. Even then, still a sucky idea.

  6. Re:Why doesn't ISS have an extensible trash module on Astronauts Throw Trash Into Space · · Score: 1

    Yes, I was serious. But it's so ridiculous sounding, it'll never be done. There have been proposals to build refuge modules to use as a bunker in the even of solar storms or potential debris fields hitting the station. For high velocity debris, loose stuff like trash works very well. Similar effect to the thin bumpers used on the outside. For radiation, the proposal is to use water or plastic (organic molecules). Seems that sewage would fit the bill there too. All it takes is a "can within a can" design. Disgusting, but beneficial.

    As far as dealing with atmospheric drag, you were pointing out the down side of what I meant by the double edged sword. But the up side is to increase the time between boosts. Theoretically that shouldn't be needed. Pessimistically, it is. With the space shuttle being retired, there goes a boost method. It wouldn't take many snafus before you'd start missing a timely boost. Is the extra mass of fuel for a boost worth it? Maybe, maybe not. But if that mass is useful in other ways, maybe.

    But mostly it's just funny to think of using human waste as something functional. Chill out and laugh.

  7. Toast on Warming a Tiny Piece of Mars For Terraforming · · Score: 2, Interesting

    I'd be curious how hot the ground would need to be to warm the tenuous atmosphere continuously blowing over it to a comfortable temperature. And wouldn't you risk creating a huge localized dust storm from the strong convection currents? Maybe you could heat a ring of land around the point you are interested in and just wait until all the dust is blown away ... but I doubt it.

  8. Re:Look out on TOP500 Supercomputer Sites For 2006 · · Score: 1

    Thank you for pointing out the obvious. Note that I talked about Sandia and LANL being in New Mexico. LANL has their own supercomputer farms. No mention of LLNL because that would screw up the joke. Do you need any more explanation? Like what manana means?

  10. Re:Why doesn't ISS have an extensible trash module on Astronauts Throw Trash Into Space · · Score: 1

    Actually, even human waste could have value if stored properly. From adding more inertia to the station (a double edged sword) to resist orbital drag, to a mass barrier around critical components (including the astronauts) as protection from orbital debris and radiation.

    Or to put it another way, in Soviet ISS, your crap saves you.

  13. More on "Mechanism of action" on Tarantula Venom and Chili Peppers Share Receptor · · Score: 3, Informative

    From what I've read, capsaicin works by altering the temperature set point for nerves. Sort of like messing up the calibration to temperature. The temperature that causes a burning sensation is lowered to below body temperature. Which also explains why cold drinks tend to help. On a related note, wintergreen oil (and related chemicals) do the opposite: set the cold sense higher. Apparently both work on the same pathway.

    Which makes me curious if anyone has combined chile with wintergreen and what happened.

    How does technology, population size and food production equate to a plague, much less an anthropomorphic deity telling us squat? It's just not that simple. If people would wash their hands more, wear masks, etc, the flu would be almost non-existent. Those are social norms, not technology or population dependent.

    Interesting point. While the US is bound to screw up some day, will the US+ screw up faster or slower? Sort of like MTBF but extended to governance. And you can actually match most of the comments today with RAID levels. Yours is RAID 0. Those who propose splitting off are RAID 1.

    As the owner of a new 2006 model human, I've found the "baby-shit orange" most often results from inserting carrots in the drooling end. Due to defects in design of digestion and skin, said unit also ends up with an orange ass. Which is all well and good, since the manufacturer (aka "mom") does not consider it a problem and in fact thinks it's hilarious.

    I will attest that the wide variety of browns coming from our unit, including orange-brown, matches the Ubuntu theme very well. Close enough that I can almost smell Ubuntu.

  23. Shutdown sequence or improved CF on Which Filesystem is Best for CompactFlash? · · Score: 1

    This might not be practical at this point in the project, but what are the chances of modifying the power-off sequence? If the OS can detect an "off", could you delay actual shutdown until writes are complete? Alternately, maybe someone needs to develop a CF with a small capacitor and RAM cache (or maybe put it on the host side). Host device gets shut down yet the CF still has enough juice (and brains) to finish the last few writes, discarding any partial blocks. Putting it on the CF might even make hot-swapping a little more robust.
