  1. Re:Applications? on Closing In On The Quark-Gluon Plasma · · Score: 2, Interesting

    GPS and Relativity? The two are unrelated as far as I know. Although satelite navigation relies on time beacons, relativistic effects due to the velocity of the satelites, or the gravitational field differences, should be insignificant and irrelevant. Please enlighten me.

  2. Re:Price vs Cost on More Incompatible DVDs and CDs Coming Your Way · · Score: 1

    Price points are set based on the results of sales in test markets. But, like you say, the consumer has a choice: Pay, or go without. If more people pay, the price goes up. If more people go without, the price comes down. You're also reght about another thing. We've lost the art of haggling.

    If you're rich enough to get one of these cars, you're rich enough to not have any friends to loan your car to.

    What happens if you leave the lights on and the battery drains? How is the system going to work when there's no power?

    Why is it even possible to leave your lights on in the first place?

  4. Price vs Cost on More Incompatible DVDs and CDs Coming Your Way · · Score: 3, Insightful

    Never, never, never confuse price and cost. The two are independant. The price of a product is what the consumer will pay for a product. The cost is the amount of money it took to produce the product. Right now, the consumer is willing to pay more for music on CD than on tape. That is why the price for CDs is higher. The fact that it costs less to produce a CD is irrelevant. The consumer is willing to pay the higher price.

  5. Re:Black holes must be flat dishes on Non-Spherical Stars · · Score: 1

    I don't know about that one. Imagine two people with ropes, pulling a load. Now, imagine those two people pull at ninety degrees to each other. The load will experience a certain force. Now, imagine the two people pulling with the same force, but this time being only thirty degrees apart. The force on the load is much greater, because the component along the direction of travel is greater, and the force perpendicular is less.

    Now, imagine two points equidistant from the black hole, one above the pole, and one in the equatorial plane. The black hole is going to subtend more of an "arc" from the polar point's point of view than the equatorial point of view. The polar point is going to be pulled from a wide angle. The equatorial point is going to be pulled from a narrower angle. In other words, the equatorial point will have a larger centerward component and a smaller radial component to the gravitational pull than the polar point.

    So, the shape of the isogravitational shell is not going to be spherical, but will be larger about the equator than from pole to pole.

    Thus ends the handwaving lesson for today.

    Yes, maybe. But these keyboards don't have thousands of keys. Either they are using an alphabetic equivalent, or are building the desired character out of component keystrokes.

  9. Re:Wal-mart's business model won't work well here. on Wal-Mart Enters NetFlix's Business · · Score: 1

    I disagree. I think most of WalMart's core customers (middle class urban North Americans) ARE likely to own a DVD player. It's not like they're all that expensive anymore. Most of the ones WalMart sells are below US$200. I don't think the online rental will fly, but I could see an in-store rental scheme working.

    I thought fiddy-cent was a website from which one could download ring tones (for half a dollar each). But Nooo, Fiddy Cent is some sort of "rap artist", I guess. If it doesn't hit my classic rock presets, it's off my radar. Maybe I should broaden my musical horizons... Nah!

  13. Opposable thumbs and palms. on Why Johnny Can't Handwrite · · Score: 3, Interesting

    I seem to be in the minority here. I find cursive to be much faster than block lettering. As a matter of fact, I've lost my lowercase character set when block printing, and I have to "render" them as "graphics" (in other words, I have to think about how they are written, rather than it just being automatic). If I have to do a lot of handwriting, I find that I get cramps faster when block printing, than using cursive.

    What I find more disturbing is that I occasionally find myself using Graffiti symbols instead of the actual block letters.

    Here's an idea. Whenever a party decides to take another party to court, they both put their legal funds into a common pool. Both the defense and the prosecution take their fees from that pool, up to half. If the prosecution wants a high price lawyer, they can have one, but the defense gets one too.

  22. Re:How is this piracy? on DMCA Vs. The Sewing Underground · · Score: 1

    The twitchy point with that idea is what if you did't mean to throw it out. What if the files accidentally fell into the trash (big wobbly stack of stuff, cat, and inconvenient trashcan for example), or if your overzealous significant other decides to clean up "that pigsty of an office". Does the mere fact of it being in the trash mean that you have abandoned claim?

  23. Statisical Challenge of GPS Orienteering on Geocaching Crackdown? · · Score: 1

    86% of all statistics are made up on the spot, usually to support an argument. Remember, the key to making up believable statistics is never use round numbers, and if you're really creative, cite an equally made up margin of error.

    And amazingly, that works 91% of the time :-)

    And Now, back to the discussion...

    Orienteering is about the journey. Geocacheing is about the destination. I lean more to the side of triviality than challenge. Orienteering is about figuring out where the destination is: The challenge of navigation. Geocoding more or less hands you the destination on a silver platter. I mean, a ten metre radius can be searched with a metal detector in what, fifteen minutes? (Most caches are either in metal boxes, or contain metal objects, from the sounds of it.) Where is the challenge?

    As for the park officials... I am sure most geocachers are responsible, conscientious people who do frequently leave less trash than they bring in. I think that educating the park officials and geocachers alike is the key. Geocachers should be encouraged to pack out trash. Park officials should be made aware that Geocachers are encouraged to do this. I don't think geocaching should be banned unless it becomes a problem. One or two people a week isn't bad. Fifteen to twenty people a day is a problem. Moving the cache around, or setting a time limit on it (it will be there on these days) would help alleviate the wear and tear factor.
