  1. Re:YRO? on School-Lunch Monitoring System for Parents · · Score: 0

    But if they give it to them under a certain condition, then the kids have to obey that condition. It's the same for gifts to adults, BTW; if I give you 10 dollars under the condition that you use it only to buy pizza, then you have to buy pizza or give me the money back. And I may also demand a way to control that you really only used it for pizza (e.g. by showing me the bill from the pizza service).

  2. Re:but what does "indeterminate" mean? on Researchers Control the Flip of Electron Spin · · Score: 3, Informative

    It means the spin does not yet have a determined value. And this can indeed be checked. There are probability inequalities (the so-called Bell inequalities, named after Bell who found them) which must hold if the result of measurement should be pre-determined for each particle. The laws of quantum mechanics violate those inequalities, and experiments by Aspect have shown that nature obeys quantum mechanics also in this respect (the violation of the Bell inequalities has been measured).

    If those measured correlations mean interaction between those systems or not depends on which interpretation of quantum mechanics you prefer. Since there are interpretations where you don't need such an interaction, it's clear that you cannot use it to instantaneously transmit information with this effect (otherwise such interpretations couldn't possibly exist).

  3. Re:what happens when the elecron is "entangled" .. on Researchers Control the Flip of Electron Spin · · Score: 3, Informative
    My question now is: are they still connected afterwards!

    No. The measurement destroys the entanglement.

    Ok, which way must I hold my ferromagnet to get good luck? Because a ferromagnet actually works through a strong bias of spins in one direction ...

  5. Not exactly ... on Researchers Control the Flip of Electron Spin · · Score: 5, Informative

    The title of the linked-to article in Physical Review Letters is:
    "Voltage Control of the Spin Dynamics of an Exciton in a Semiconductor Quantum Dot"
    (Emphasis by be)
    Now an exciton is something quite different from an electron.

    Remember, this is the same government that tapped the phones of the Black Panthers in the 1960's, arrested innocent people, killed innocent people, overthrew the democratically elected president of Chile. Our government stinks with evil.

    GWB is in power since the 1960's? :-)

    Actually the term I know for "free as in beer" software is "Freeware" (note that there's no "soft" in between).

  9. Re:If your child was kidnapped... on GPS-tracked Clothing · · Score: 1

    Read again: "If kids were usually wearing such clothing ..."
    The probability of the child wearing it would be much higher than the child not wearing it (that's what the "usually" part implies), so the kidnapper would do so just in case.

    One possible solution to the "naked child problem" was already given. Another would be to hide the child so that it cannot be seen from outside (e.g. use a mini transporter).

  10. Re:If your child was kidnapped... on GPS-tracked Clothing · · Score: 1

    No, that's assuming they don't want the child's position to be tracked any more. Which is, of course, a common desire for all kidnappers.

  13. Re:Taco speaks English as a first language? on History of Netscape and Mozilla · · Score: 1
    So when someone writes hard-to-follow, yet syntactically correct, spaghetti code its not their fault others can't read it? I'm sorry but a writer has a responsibility to make thier sentences easy to parse.

    Strange, I didn't have any problems to parse it. And I'm not even a native English speaker.

    BTW, speaking about the writer's responsibilities ... using "its" instead of "it's" and "thier" instead of "their" isn't exactly helpful in parsing :-)

  15. REXX with other backends on O'Reilly on the Virtues of Rexx · · Score: 1

    One nice thing about REXX is its "outside environment" concept. This basically anables it to be added to about anything which accepts commands. For example, EMX's gdb port for OS/2 added REXX support. This way, you could actually write "debug scripts". See an example in this usenet posting.

    all it's provided competitive options for are either tools that pretty much everyone uses, like text editors, or stuff that's of interest to programmers, like computer operating systems and associated tools.

    I would have put operating systems in the class of stuff that pretty much everyone uses. How many computer users do you know who don't use an operating system?

    You didn't specify the OS.

    On Linux, there definitely is (Ok, I didn't test it, but I can't imagine what could go wrong). The scroll wheel is usually mapped as "mouse button" 4 and 5. Bind those globally with the appropriate modifier keys in your window manager configuration to an execute command which executes a command to up/down the volume (e.g. for alsa, "amixer sset Master 1%-" on modWhatever+button4 and "amixer sset Master 1%+" on modWhatever+button5 should work (untested)). If you are using Gnome or KDE, there might also be a way to directly access the corresponding volume control applet from your Window manager.
