  • Captchas are little tests meant to insure that a web form is not being gamed by a program. John M. Willis has a collection of what he deems the Top Ten Worst. Since I'm a geek, I liked this one:

    [Challenging Captcha]

    [It's been a long time since I did that kind of thing, but I think the answer's zero. The π/2 term shifts the sine curve to the right so it has a minimum at x=0, hence the derivative is zero there. Yes?]

  • Lore Sjöberg has the scoop on PowerBocks:
    Powerbocks are devices that you strap to your feet because you feel that it's been way too long since you fell down. They're like stilts, in that they make you a bit taller. They're like springs, in that they help you jump higher. And they're like replica swords, in that they prove you have more money than sense.
    There's video!

  • And in our occasional Aieee! We're all gonna die! series, we have this:
    A spectacular, rotating binary star system is a ticking time bomb, ready to throw out a searing beam of high-energy gamma rays — and Earth may be right in the line of fire.
    Fine. As long as it waits until after Star Trek comes out …
