  1. Err, it doesn't look like it on New Asteroid Becomes Earth's Biggest Threat · · Score: 1

    On May 4th 2102 Asteroid (2004 VD17) looks like it is about 2AU away from Earth based on this site: http://neo.jpl.nasa.gov/cgi-bin/db_shm?sstr=2004+V D17&group=all&search=Search

  2. Re:WTF? on Near Light Speed Travel Possible After All? · · Score: 2, Insightful

    What if, after you have been accellerating for months, but are still at only 50% the speed of light, you hit a 1 lb chunk of rock/dust/ice that fell off some asteroid...
    50% of speed of light = 1.5 x 10^8
    1 pound = 0.4536 kg
    Kinetic energy = (5.1 x 10^15)
    Ouch.

    You'll only take that amount of energy if the entire kinetic energy is transfered to your ship. I'm guessing, at that speed, the rock will just pass through your ship creating a nice cylindrical hole. Any thoughts?

  5. Idea of "planet" is outdated? on New Tenth Planet Has a Moon · · Score: 2, Interesting

    IMHO, since we are having such a debate as what is a planet and what is not, then the notion of a planet has outlived its usefulness. Out of all of the large rocks orbiting the sun, why select some to be called planets and others not? Is there a need to draw such a distinction? Labelling some objects as planets and others as not is as ridiculous as deciding upon "x" meters of string to be known as a standard long or short piece.

    If you say we need "planets" so that objects may be easily classified, then I sat that the application of the data determines the measurement for classification. And there are countless measures such as size, mass, distance from the sun, eccentricity, angle from the ecliptic, or any combination of these and more.

  6. Arrow has contradicted himself on When More Information Isn't a Good Thing · · Score: 2, Interesting

    After RTFAing...

    How about the service offered by LegalMetric LLC, a start-up founded by patent lawyer Greg Upchurch? Contemplating a patent-infringement case in Delaware? For $795, Mr. Upchurch will tell you which judges rule most swiftly and which tend to favor patent holders. Making a motion for summary judgment? Mr. Upchurch can tell you how the judge has ruled on similar motions versus his peers.
    - Will possibly make apparent significant biases of one judge over another, and allow procedures to be setup which monitor or train judges to become less biased?

    Imagine a place with uncertain weather where food is plentiful in rainy spots, but not in others. Residents, in essence, buy insurance. The lucky feed the unlucky. No one starves. Then it becomes possible to buy accurate weather forecasts. One who buys the forecast knows whether he needs insurance or not; he profits. But the total amount of food available is unchanged. And if everyone buys the weather forecast, the insurance market becomes impossible.
    - Knowing where food can be produced and where it cannot can help people choose where to live. Perhaps even develop a more effecient way to produce the food.

    If deciphering the human genome allows each of us to know the precise odds of contracting a dread disease, life and health insurance will be very tricky.
    - Identifying which genes lead to diseases is the first step to preventing/eradicating them at the genome level for everyone.

    The only time that "too much information" could be harmful socialy, as Arrow put it, is when that information is shown to a minority and withheld from the majority. In fact, this is the lack of information that is not beneficial.

    Ultimately what Arrow is trying to say is that information given to one party but withheld from another can be detrimental to the later. Seems common sense to me.

  7. This is why /. editors keep post electic universe: on Supernova 1987A Decoded · · Score: 1

    It's to slashdot the site, nuking it off of the face of the earth.

    Electric Universe is a well-known crackpot site, built on the most absurd pseudoscience. They're the same outfit that predicted a large explosion when Deep Impact hit Tempel 1.

    As usual, the /. editors display their utter inability to distinguish between science and pseudoscience. Idiots.

  8. I'd love to oblige on Earth Departure Movie From MESSENGER Spacecraft · · Score: 2, Funny

    I think slashdot news posters must *love* to get people posting comments about their links getting slashdotted. So, here is another rant... "ah, slashdotted already".

    Either that or they have a running king-of-the-hill contest on who can slashdot a site the fastest.

  9. Example of AI helping understanding on Artificial Intelligence for Computer Games · · Score: 1

    AI _can_ help with data reduction, but not understanding.

    TD-gammon is a classic example of how AI has improved the understanding of a particular subject of study. Gerry Tesauro created an AI backgammon player that not only rivaled the best grandmasters of the time, but also allowed a new strategy of oppening play to surface as the dominant style.

    http://www.cs.ualberta.ca/~sutton/book/11/node2.ht ml:TD-Gammon learned to play certain opening positions differently than was the convention among the best human players. Based on TD-Gammon's success and further analysis, the best human players now play these positions as TD-Gammon does

  10. Is *he* a good programmer? on Hiring Good Programmers Matters · · Score: 1

    Or look at the iPod. You can't change the battery. So when the battery dies, too bad. Get a new iPod. Actually, Apple will replace it if you send it back to the factory, but that costs $65.95. Wowza.

    and then

    Apple made a decision based on style, in fact, iPod is full of decisions that are based on style. And style is not something that 100 programmers at Microsoft or 200 industrial designers at the inaptly-named Creative are going to be able to achieve, because they don't have Jonathan Ive, and there aren't a heck of a lot of Jonathan Ives floating around.

    If he considers the inability of easily replacing a battery inplace of style a good feature of the ipod product, then I will never ever want to buy his software.

  13. Programming technique is flawed on Is Programming Art? · · Score: 1

  14. Good article on Our Brains Don't Work Like Computers · · Score: 1

    What the hell are people complaining about? I say good post Roland. I find this article quite interesting. I have always thought that given two stimulii the human brain would process those stimulii in parallel, and only synchronise upon the process of making a descision. This very interesting research shows that we can only process one stimulii at a time. As a result, perhaps we could create neural networks and artificial brains that are more powerful than humans much sooner that anticipated.

  15. Re:Where's the Sony PS3? on 25th TOP500 List Released · · Score: 1

    The graphics constitutes 1.8 Terraflops of the ps3's 2 Terraflops, hardly what can be called useful computation. I have a pencil on my desk that can do easily over 200 Exaflops by maticulous "calculation" of how photons that hit it should be absorbed or reflected to create the stunning diffuse, specular and anisotropic lighting that I am observing.

  16. No limit? on $100,000 Poker Bot Tournament · · Score: 2, Interesting

    I heard that no-limit is much harder for a computer than limit poker. A player must calculate percentages with limit poker, and bluffing is obviously limited, thereby reducing the "human intuition" aspect and increasing the simple number crunching aspect. If the AI poker tournament is no-limit it will make things very interesting.

  18. Re:Another great review: on Review: Star Wars Episode III · · Score: 1

    Perhaps the "prophecy of the one who will bring balance to the Force" was misinterpreted after all: Perhaps the prophecy was really fulfilled not by Anakin destroying the Sith order, but by Luke humanizing the Jedi ethic.

    Anakin did restore balance to the Force. There was an over abundance of light side Jedi, and only a few dark side Jedi. At the end of episode three, there were two Sith (Palpetine and Darth Vader) and two light side Jedi (Yoda and Obi-Wan). So, in fact, the prophecy was fullfilled, from a certain point of view.

  20. Re:Regarding Lightsabers on The Feasibility of Star Wars Tech · · Score: 1

    The way I understood it in the movies, is that the Force is everywhere. Midichlorians are just an interface between living things and the Force. So Jedi simply "talk" with the midichlorians to use the Force, much in the same way that you "talk" with neurons in your body to use your muscles.

  21. Interesting that... on Cassini Confirms New Moon of Saturn · · Score: 4, Interesting

    the waves caused are asymetric, as if the moon is moving faster than the immediately surrounding debris. But thats impossible, because it would move the moon to a higher orbit, or the debris to a lower one, right? Can anyone explain this seemingly wierd phenomenon? Also notice the waves caused on the inner darker ring, what is the cause of that?

  25. Re:Either way. on Hitachi Predicts 3D Hard Disks by Year's End · · Score: 2, Funny

    Hmm, you'll have to be more specific. How compressed should the Library of Congress be, or in what encoding? Setup a code where 0 is null and 1 represents the Library of Congress. Then the whole Library of Congress can be fit into a single bit, in this case on a 200GB hard drive you could store around 1600G Congress Libraries.
