    Bad variable names can't be helped, though...
    Well, unless you use a langauge which gets rid of variables and names.
  2. Take the next step... on The Tech Used to Catch Vegas Cheats · · Score: 1
    The odd aren't just stacked in the casinos favor, they also throw out players who win too much. Casinos use the surveillance systems and facial ID systems to detect and bar players who are card counters. Card counters are not cheaters, they are people who are really good at math who carefully observe what cards have been played and place bets accordingly--just as expert poker players do consciously or unconsciously.
    Now take the surveillance one step further. They've already got the camera's everywhere. So just modify your image recognition software to identify the cards as they are dealt out, and add a in a computer with a card counting algorithm. Voilà, now the casino can cheat, and on an automated wide-spread level. Whenever the shoe turns against the house's favor, the pit boss can nod to the dealer and they reshuffle the cards. All your cash are belong to us!

    Sure. Just sell the gas at market value. As a result, only a very select minority of people would be able to drive their cars, and everyone else would be essentially out of luck.
    Well, either it'll be greedy rich people fueling up their jetliners to fly to Paris for cocktails. Or, it'll be greedy rich people trying to make more money by putting the gas towards better uses, like say, for truck's bringing produce to market. (Oh, and you're living in a dream world if you think rich people wouldn't just pay people to have a portion of their ration (what problem were we trying to solve again?))
  4. Eh... on Henrico County iBook Sale Creates iRiot · · Score: 1
    It's like gas rationing back in the 70s. Who was the brilliant idiot who came up with cars waiting in line for gas? Just have one person standing there taking license plate numbers and telling people when to come back at a reserved time. Is it so hard?
    Or, if you want a really radical solution, you could try selling stuff at market value. Voilà, no lines, no need for rationing.

    Yes, but is it recursive?

  6. Re:100nm? on Branched Nanotubes Offer Smaller Transistors · · Score: 3, Informative
    Am I missing something here?
    Yes. The 65nm refers to the transistors gate length, which is only a small portion of the transistor. See some transistor cross-sections. Look at the first diagram, look at the red colored rectangle above and between the two blue regions labeled "S" and "D" (for "Source" and "Drain"). That red part is the gate.

    ...but they don't have a right to copy all of a libraries' book, nor do they have the right to distribute (AKA show to you) any pages from these books
    I guess that means that the Google Cache and the Wayback Machine are illegal.
  8. DrScheme on Best Language for Beginner Programmers? · · Score: 5, Informative

    Give DrScheme a look. Nice graphical IDE, libraries, dead simple syntax. Free. Different language levels to cater to the learning process. And pleanty of introductory texts.

  9. Function length on Hiring Good Programmers Matters · · Score: 1
    I can't recall if it was Pike, Kernighan, Ritchie or Raymond that said function length is a better indicator of quality than indentation.
    Here's an interesting paper which is somewhat relavent to your point...
    Observes from a number of experiments that the fault curve rises logarithmically with function size until reaches a point at around 300 lines of code at which point it becomes quadratic. The implication is that both small and large components are unusually error prone. The paper then develops a mathematical model of reliability based on the properties of the human short term and long term memory which explains this.

  12. Re:That's nice.... on A Video Tutorial of SLIME · · Score: 1
    Haskell syntax is very minimal. It's almost entirely function application by juxtaposition and function application by infix operator. There's not much else to it.
    Not that I disagree with your other points, but Haskell isn't that regular. Or at least the Haskell code that I write is littered with list comprehensions, and do-notation, and lambda abstractions, etc.
  13. Re:Haskell - another write-only language like Perl on A Video Tutorial of SLIME · · Score: 1
    Eh, that was quicksort in the J language. Quicksort in Haskell looks like...

  16. Economics 101... on Calculating the True Worth of Software · · Score: 1
    I hate it whenever I see a sentence that equates the cost of creating software to the cost of copying the software.
    Well, if we go back to Econ 101, we'll discover that in a competitive market, the actual price is driven down to the marginal cost of production and you'll have a hard time recovering your fixed (sunk) costs. So if you want to make money you have to make sure your fixed costs are low or you have no competitors.

    If you think this is bad, then you should plan on being very scared of IPv6 since that will have the ability to give every device a permanent non-NATted IP address that will uniquely identify you.

    And this is paranoia on crack... it assumes that people will ALWAYS do the wrong thing and will ALWAYS try and screw you about, and that customer profiling NEVER results in a better service.

    Your 'rights' are only rights so long as you obey the law.
    I think you've got that backwards. Rights aren't defined by law. The law is only just (and therefore worthy of following) when it respects the rights of individuals.

    No. That's incorrect. At least for those societies which govern themselves under the (English) system of common law.
    As for rights, I feel the major problem we have is that everyone feels everything is a right.
    That's the problem with a government with enumerated powers. Everything is a right, and the government only has limited power to remove those rights from you (after due process of law). Here's some snippets you might recognize...

    The point of DRM is to be in the way when you try to distribute something.
    But what if you want to distribute something to yourself? You know, something far-fetched like ripping a CD to MP3's. Is no one in the future going to want to do something similar? Or maybe there won't be any incompatible DRM schemes in the future, so it will always be possible?

    That's weird, I thought an efficient scientific society would rein those lazy bags of protein who couldn't follow the rules. Seeing how the threats to grammar aren't too thinly veiled. Our collective conscience shouldn't stop us from sufficiently censoring those deficient members of our species. Either we have too much leisure, or too much caffeine in our veins. Our feisty, omniscient ancients are probably very dissappointed in their heirs. Seize the day, or forfeit tomorrow!
