  1. Give me a track point (and git offa ma lorn) on Touchpad Meets Morphing Keyboard · · Score: 2, Insightful

    This seems really neat and all. However...

    I have experience with two laptops. One had a touchpad, the other had both a touchpad and a trackpoint.

    When I only had a touch pad, I carried around an external mouse (well, trackball; Logitech Marble Mouse to be exact)---and I dreaded the times where I'd forget to bring it along and have to use the touch pad. With my current laptop which has a track point, I don't even think about whether I should bring along an external mouse---the track point works great and it's more convenient to not have to plug anything in. [and with edge scrolling and infinitely wide edges, the touchpad now works as a "scroll pad".]

    Granted, it the touchpad-only laptop was el cheapo and perhaps the touch pad wasn't the greatest. But still---track points are really great input devices (at least the one I have), and they're small enough to fit on practically speaking anything.

    So why bother with turning your keyboard into a touchpad? I imagine the user might trace a vertical line, intending to move the mouse around, but the device going "oh, r-f-v-space, what an interesting key combo." Or the user pawing and poking the keys somewhat less than straight, and the device not picking up on it. It seems... with my experience of touchpads, this seems like it could be dangerously full of fail and meh.

  4. Yeah, the arguments stink on US Gov't. Ending Its Hands-Off-the-Internet Stance · · Score: 1

    If users do not trust that their credit card numbers and private information are safe on the Internet, they won’t use it.

    And the current system works fine, so that's an argument for government hands off, right? Or maybe it's an argument for tightening credit/debit card security? I mean, the crypto for transmitting credit card numbers works fine as is...

    If content providers do not trust that their content will be protected, they will threaten to stop putting it online.

    Then the pirates will have the online distribution market all to themselves. Yeah, I'm sure the legit content distributors are going to like that.

    If large enterprises don’t have confidence that their network will not be breached over the Internet, they will disconnect their network and limit access to business partners and customers.

    Any sane large organization should realize that it will have security incidents. I see an abundance of organizations online today. So this is an argument for... what, exactly?

    If foreign governments do not trust the Internet governance systems, they will threaten to balkanize the Domain Name System which will jeopardize the worldwide reach of the Internet.

    Uh-huh. And the US having control of the root zone engenders trust exactly how? I see this as a great argument for less US gov involvement.

  6. The precise definition of the mandelbrot set. on Scientists Develop Financial Turing Test · · Score: 1

    The quintessential chaotic system, mandelbrot's fractal, is just such an example. You take any imaginary number c = p(1).

    The way I always heard it is you define f_c(z) = z^2 + c. Then you compose f_c with itself n times (for n = 0, 1, ...), and evaluate f_c^n at 0. So f_c^1(0) = f_c(0) = 0^2 + c = c.

    Then you say p(n+1) = p(n)^2 + p(0), and you examine the value of p(infinity) for various values of c.

    Eh, $\infty \not \in \mathbb{N}$. You examine the values of p(n) for all n.

    This will draw the famous mandelbrot fractal.

    To be exact, a point c is in the mandelbrot set if there exists a K such that for all natural numbers n the norm of f_c^n(0) is at most K.

    It other words, by iterating (z -> z^2 + c) you never get further away from (0, 0) than a distance of K.

    Side remark:

    Say I'd give you 5 consecutive digits and ask you for the position in pi. Since there are infinite solutions to this question, it's not actually predictable

    So you're saying I can't tell you what the answer is before... well, before what?

    Also, since you're asking for the unique solution, your question is bogus. Why do you ask it?

  7. Maybe you want quantum computers? on What Is Time? One Researcher Shares His Exploration · · Score: 1

    Now imagine a computer that uses a reversible logic system that is reversible, would that computer have a time-symmetric operation?

    Well, quantum computers work something like that.

    You may want to think of the state of a classical computer as a bit vector, a member of {0, 1}^n for some n. In the same vein, the state of a quantum computer is a member of C^{2^n} for some n; it's a 2-to-the-n-dimensional complex vector. Oh, and it has length 1.

    The state transformations you can do are described by unitary matrices; in particular, they are invertible. Say you apply U to a state x and get a state y. Applying U^{-1} to y will still take time, though (is my understanding; but I'm not certain). And you can do a measurement which loses information.

    So, quantum computers are maybe not exactly what you want, but you might want to look into them.

  15. And they'd be right on iPad Will Beat Netbooks With "Magic" · · Score: 0

    For some people here at /. Apple could give you money for taking an iPad (or any other Apple device) and they'd still complain that they didn't get enough money.

    It takes time carrying out that transaction. Maybe I could earn more doing something else with my time.

    Maybe I have to fill out a contract with Apple to get the money, and I'm worried about the contract. Maybe I'm worried enough that I need a lawyer to read and understand it for me. That costs money.

    Apple of course needs to compensate for that, and the transaction time, and a little more, for me to accept.

    Okay, I'm stretching the argument thin, and it only works for unrealistic values of transaction cost and donation size, but there are rational reasons for saying no to free money (with or without the extra free iConsumerElectronics).

    And doesn't it go the other way around as well? Aren't there a few Apple lovers who'd complain about getting too little money if someone gave them money and a Windows/Linux CD?

    I may be completely misreading you, but what you're saying sounds something like this:

    The solution to fragmentation is to create a new, better and unfragmented platform to compete with everybody else.
