  1. Re:Emotion? on Is Programming Art? · · Score: 2, Insightful

    Good art communicates that which cannot be said.

    So a book of poems or prose can never be good art?

  2. Mod the Anonymous Coward parent up... on China Signs Anti-Spam Pact · · Score: 1

    He beat me to it :)

  3. I might as well try an example :) on When Computers Were Human · · Score: 1

    I might as well try an example...

    Using just the first three terms of the infinite summation for the cosine function:

    cos (0.3 radians) = 1 - x^2/(2!) + x^4/(4!) (easy pattern, nice for memorizing)

    So -> cos (0.3 radians) = 1 - 0.3^2/2 + 0.3^4/24 = 0.9553375

    Comparing to calc.exe's cos(0.3) = 0.9553365

    So it was quite a good approximation, and easy to calculate too! (easier than I thought, actually)

  4. Re:parallel processing techniques... on When Computers Were Human · · Score: 1

    I think that a good way to calculate trigonometrical functions on one's head is to use the Taylor series expansion of those functions. Not that it's easy, there are still some quite complicated operations to do, as you can see in the formulas. If one of you ever gets stranded on a desert island and for some reason needs it, I'd just recommend making a table as the ones those "computers" helped calculating :)

    I think it's called complement arithmetic, actually. I may have misunderstood his stament though. What carry are you talking about?

    What if there are people/beings or space-gods inside? Or Daleks?

    Maybe we can apologize?

  9. Friend who studies all kind of space things? on Astrologer Sues NASA Over Comet Probe · · Score: 2, Insightful

    The other comment I've heard, from a friend who studies all kinds of space things, is that he hoped NASA picked their comet-target right, because they probably changed its trajectory in minute ways, and it could come back to haunt us if it happens to be cyclical with a very long period, and NASA didn't know about it, and it came back with something that looks like a collision course in the future.

    Tell that friend who "studies all kind of space things" to study some logic and probabilities too. Since all calculations done show that the comet isn't expected to impact Earth neither with the previous nor with the new trajectory, the probability that we have made it crash Earth in a few million years is the same that we have avoided a future crash.

    No, that's actually the fault of the wallet/large suitcase vendors, didn't you know? ;)

    It's redundant with common feeling and thought of (at least) the /. crowd.

    Although I'm not American, I have to agree... I've just found this, and this. Oh, maybe this calls your attention more.

    So we should sue the guys who invented the internet, TCP/IP, HTTP, FTP, IRC... Let's go for it, I can't think of anything better to make with our money :)

  16. Re:Question... on Britain to Pilot GPS Speed Governors · · Score: 1

    Even a better solution is not to interfere with the driving in any way, until the technology is sufficiently advanced in order to do it when it should be done (which might be many years from now... suppose you were taking someone to the hospital in your car for example). Or at the VERY least, providing a way to override all interference - but this might not be a good enough solution.

  17. Re:Question... on Britain to Pilot GPS Speed Governors · · Score: 1

    Once upon a time, I almost crashed into a car from behind (my fault, all cars were slowing down, it was a curve and I didn't notice until it was a bit too late). If he hadn't noticed and accelerated when I was already breaking behind him, maybe I would have run into him...

    Well, if you're going to such detail, maybe you should add in the costs of the musical instruments too, which are MUCH more expensive than the pc's. And yes, I'm more than aware that some churches have good acoustics for concerts, but for serious recordings with 100-piece orchestras I'm not so sure... Are you?

    And give the editors a break. It's a miracle the site is still operating, let alone somewhat useful given the traffic/abuse they get currently.

    Did you know that they actually get money from operating this site? And they don't even bother to read it :) This dupe is from a long ago compared to most of them, which usually occur with a day or two interval...

    The cost of a broadband connection is about the same as the cost of renting a recording studio? Which planet do you live on, I want to live there too! Or maybe not...

    Plus, did you know that it takes much harder work to become a good musician than to become a good software engineer?
