  1. Re:Bull. on Analysis Says Planes Might Be Greener Than Trains · · Score: 1

    And what about the oil products and CO2 used to make the wind farms out of in the first place.

  2. Use Sci-fi propaganda on How Do You Greet an Extraterrestrial? · · Score: 1

    The best way to get an extraterrestrial race to become comfortable with the idea of other races would be to infiltrate their media/communication networks and plant ideas that aliens aren't that scary, and maybe they could be quite nice.
    - Start with "The day the Earth stood still" (or alien equivalent).
    - Move on to some Star Trek like series
    etc.
    Maybe set up some conspiracy theory to get the population to think for themselves. In general, gradually get the populous happy with the idea of aliens.
    Then appear and say hello.
    Kinda like what's been happening on earth since mid 20th century.

    I for one will welcome our new extraterrestrial overlords

  3. Re:Before we get all sweaty about terms on How Software Engineering Differs From Computer Science · · Score: 1

    I agree. Mathematicians have provided the tools for science to use, but that's not what they are there for.

  4. 3D Input but no 3D output on Sony Unveils PS3 Motion Controller · · Score: 2, Interesting

    Did you notice how he kept missing the ball?
    He can control where the bat is in space, but he has absolutely no idea where it is relative to the ball. This may work in combination with 3D TV, but even that will have calibration problems.
    Sony's controller has knows it's absolute position, and the Wii knows it's relative position. The question is, when would you need to know a controllers absolute position?

  5. Re:Windows of opportunity to learn on The Myth of the Mathematics Gender Gap · · Score: 1

    I don't suppose you could list what should be learnt at each age. I'm not picking a fight. I'm genuinely interested. I totally agree that foreign languages should be learnt as early as possible. For example, In your opinion what age should we learn about:
    Maths
    Programming
    Geography
    The opposite sex
    Politics
    Music
    etc...

  6. Re:You can't blame it all on the qunats. on Paul Wilmott Wants To Retrain and Reform Wall Street's Quants · · Score: 1

    If it's got non-zero skew then it's not a Gaussian

    True

    If it's got non-zero skew then it's a skew-normal distribution.

    Not necessarily true. There are lots of other distributions that have a non-zero skew which have CDF's that are much easier to calculate.

  7. Re:That's just fiscally stupid. on Microsoft Raises $3.8B in Bond Sale · · Score: 1

    They still have a net $25bn of cash. This would be hit by inflation.
    If they raise debt and get rid of all their cash then I'd subscribe to the inflation hypothesis.

  8. Malcolms on Test Driving the Wolfram Alpha · · Score: 1

    Does it convert into Malcolm's?
    "A wavelength parcel of ten KH/Z operating in 4 Dimensions equals one Malcolm"

  9. Re:If was the Li's formula on The Coder Behind the Mortgage Meltdown · · Score: 1

    taking into account only single correlation parameter

    That's a single correlation parameter per pair of mortgages. If you have N mortgages then that's N^2/2 parameters.
    This is one reason why people can't agree on a price for the CDO's. No-one can agree on the underlying correlation matrix.

  10. Re:What does it mean to be Linux? on He's a Mac, He's a PC, But We're Linux! · · Score: 1

    I agree with all the above.
    It doesn't even say that you can use it without paying any money. To most new users, that's the number one benefit.

  11. Re:Well, I think on Attempting To Reframe "KDE Vs. GNOME" · · Score: 1

    You could say it is an Open Sores project. So to speak...

    Clap clap
    Bravo!

  12. Re:How Do Militaries Treat Their Nerds? on How Do Militaries Treat Their Nerds? · · Score: 1

    Like cannon fodder.

    I love it!
    Where do I sign?

  13. Re:Yes, it bloody well is. on The Formula That Killed Wall Street · · Score: 2, Informative

    2 dollars are held by the food/energy producer. These are just for bartering. The point of the model was that the final state was the same as the initial state.
    The money in the above economy comes from being able to grow food/produce energy and to be able to do something with it (cook the meal).
    My example was to show that you can create and pay off debt and interest without having to magic more money into existence.
    The graphs could be exponential because production is exponential.
    What you may be alluding to is that the debt the food producer holds could also have been traded, as money. This HAS been magicked into existence and will continue to exist until the debt is paid or defaulted on.

  14. Single Correlation parameter? on The Formula That Killed Wall Street · · Score: 1

    The article keeps going on about a single correlation number. That's only true if there are 2 mortgages, and the copula is a bivariate normal distribution (see page 14 of the paper )
    Real CDO's have more than 2 assets, so the correlation matrix used is key. This is a reason why prices can't be agreed for CDO's. Everyone uses different correlation matrices. Option pricing has a market because Black Scholes only has a volatility parameter to trade around.

  15. Not exponential on The Formula That Killed Wall Street · · Score: 1

    I borrow 1 dollar from you and promise to repay 2 dollars.
    I buy food and energy from you for 1 dollar.
    I cook a meal in my restaurant.
    You eat at my restaurant and pay me 2 dollars.
    I eat the leftovers.
    I return 2 dollars to you.

  16. Jet Pack Trainer on Jet Pack Runs For Hours On Water · · Score: 1

    It would be cheap to learn to fly on this, out in open water where crashing isn't dangerous. Once mastered you could progress to the real, expensive, dangerous, fuel powered jetpack.

  17. Controllers on UK University Making Universal Game Emulator · · Score: 5, Insightful

    How are you going to play the games?
    What is pong without the rotary control?
    Imagine (in 50 years time) playing Wii bowling without the wiimote.
    How are you going to get a light gun to work without a screen that does a full refresh.
    etc.

  18. Doesn't affect me on UK Email Retention Plan Technically Flawed · · Score: 1

    I live in a Faraday cage and only come out to post on slashdot.

  20. Hanging on just long enough... on Michael Crichton Dead At 66 · · Score: 2, Interesting

  22. Re:Why the tone in the summary? on LHC Shut Down By Transformer Malfunction · · Score: 1

    radio-isotope dating

    Much better than online dating!

    I'll get my coat.

  23. Another middleman on Why Starting a Legal Online Music Vendor Is Tough · · Score: 1

    Step back a bit. Why should online vendors be able to profit from someone else's work. Having a record company between the customer and the artist is bad enough, without having to add extra middle men.
    What service does the 'Legal Online Music Vendor' supply? If it's selling other peoples music then it is already obsolete.

  24. Re:slashdot fails at maths yet again on The London Stock Exchange Goes Down For Whole Day · · Score: 1

    Agreed. Statistics are about the future, not the past. The event has occured, so the clock starts ticking again.

  25. eh? on What To Do With All of My Gadget Chargers? · · Score: 1
