  1. Re:Barking up the wrong tree. on More Bad News From The Hellmouth · · Score: 1
    It was pointed out before that this is not "geek profiling".
    A year or so ago, some public official on Long Island was forced out of office after he referred to a group of rowdy, mostly black teenagers as "those monkeys". Activists complained that he had called them monkeys because they were black, but he claimed that he had called them monkeys because they were acting like monkeys.

    Now, I don't mean to defend this guy, since I don't remember the story too well anyway. But I always felt that it was the activists who were racist, not the official. Because they apparently believe themselves that black people are monkeys, when they saw someone call a bunch of black people "monkeys", they assumed it was because they were black.

    So Mr. Katz, do you believe that being "violent" is equivalent to being a "geek"? Apparently you do, because although the MOSAIC folks have only said that the program is intended to detect violence, you assume that they're looking for "geeks".

    If, in fact, a test which is designed to detect violent students happens to flag a lot of geeks, then frankly, maybe geeks are violent. But I don't think this is the case, so it is unfair to imply that this is "geek profiling".

    You know, I don't mean to flame, but I have found all of Katz's recent articles to be fundamentally flawed, and apprently many /. readers have agreed. Is it time to take this guy off the payroll? (If in fact he is on the payroll?)

    (Disclaimer: I think MOSAIC-2000 is a very, very, bad idea. I just disagree with this particular objection. For the real problem here, see Jerf's comment and my response to it.

  3. Re:VB compiled on Zona Research Does Programming Language Poll · · Score: 1
    I doubt anyone is still reading this, given /.'s collective attention span, but I'll provide some facts here anyway:
    Another poster has pointed out that VB executables can be dynamically linked to get the same effect in the right environment, which is nice, but that they are often statically linked with a large runtime and are, therefore, hogs.
    I don't know what post you're referring to, but this is incorrect. VB programs are always dynamically linked. It is impossible to statically link a VB program with any other compiled code. This is something that many VB programmers have been complaining about for years, although I understand the reasoning behind it. (You haven't seen many VB programmers worried about the Y2K bug, have you? That's because MS simply distributed a patched runtime library, and most VB programs were instantly fixed.)
    Getting back to the original issue, which performs better: Java or VB?
    In theory, since VB compiles to machine code (by default), and Java compiles to bytecode (always, AFAIK), VB should be faster. In practice, of course, the quality of the compiler and the runtime is a much more significant factor, so YMMV.

  5. Reproductive strategies on Global Population Implosion? · · Score: 1

    I'm surprised that with all the speculation going on here, no one has yet mentioned the r-strategy vs. K-strategy model of reproduction. It explains this situation nicely.

    There are two different ways that a parent can increase his or her presence in the global gene pool. The obvious one is to have more children (r-strategy). Another way, though, is to work to increase your offspring's presence in the gene pool (K-strategy). Because resources are limited, it inevitably comes down to a choice between more children and "better" children.

    The more an individual's success correlates with the resources that were expended on him, the more useful K-strategy is.

    In "undeveloped" countries, a healthy, well-dressed, college-educated individual isn't much less likely to be eaten by a lion than one who is naked and starving. Therefore, r-strategy is preferable, and the population grows rapidly.

    In "developed" countries, however, things like education and wealth do make a difference in reproductive success. So instead of having lots of children, families have one or two children, and spend a huge chunk of their income on tuition, doctor's bills, etc. The result is a lower rate of population growth.

    This brings to mind an interesting question... How much can the population shrink without compromising the "reproductive fitness" of the species? What happens if college educations become so expensive, and so universal, that very few families can afford to have more than one child? I suppose the population would shrink, until the amount of resources available per person is large enough to support population growth once again.

    Wow, that's an interesting idea, and it just sort of occurred to me now. If that theory really works, then we shouldn't have to worry about population growth... it will stabilize naturally. Anyone disagree?

    pluging data into the continuous function 12 = 6(e)rt (where rt is the exponent and r=present continuous growth rate) solving for T reveales we will reach 12 billion around 2050.
    Yes, but what is your r? (I'm afraid I don't have a calculator handy to figure it out myself.)

    The rate of population growth is the average number of children per family, divided by two. White Americans, for example, are actually averaging less than two children per family these days -- in other words, their population is shrinking. Being that white Americans represent one of the wealthiest populations in the world, it is reasonable to expect that as the "wealth" of the world increases, growth rates will decrease.

    That's the logic behind this story.
  7. Re:Conformance is not the danger! on Software to Predict "Troubled Youths" · · Score: 3
    This test is not dangerous because it will somehow enforce "conformance". The danger is that the test is reliable, but not reliable enough. There are four permutations of "person is violent" (assume for a moment that this is a simple boolean, for the sake of argument), and "test says person is violent." The true danger here is that a large number of people will become "diagnosed" as violent who are not, known as a "false positive". The society will then act on this false information, possibly in drastic and damaging ways. (false negatives aren't half as disturbing; few violent people shoot up schools)
    Just to amplify this point:

    Back at the height of the AIDS scare, clinics that did a lot of AIDS testing often had one or more full-time counselors whose primary job was to convince patients that they do not have AIDS. Many of these patients had gotten positive test results in the past, but later came up negative on more reliable tests.* What these people had trouble understanding is that when you test for something that is very rare in the general population, such as AIDS, there will be far more false positives than true positives.

    So let's say that this test is supposed to flag the 1% of students with the greatest potential for violence, and let's say (very generously) that it's 90% accurate. On this test, 0.9% of those tested will be correctly marked violent. 0.1% will be marked "safe", even though they have the potential to be violent. 89.1% will be correctly marked "safe". And 9.9% will be incorrectly flagged as violent.

    In other words, given this exmple, for every violent student that the test catches, more than ten "safe" students will be incorrectly "caught".

    They may widen their criteria for violent students, which would make the test slightly more valid. However, it is likely that the test will be far less that 90% accurate, increasing the ratio of false positives/true positives even further.

    *I'm not sure if I can back up this AIDS story, so feel free to consider it a fictional example if you wish.

    Don't flame me, I'm not trying to equate this with Linux, it's not "free" in any sense of the word. I only mention it because it shows that Microsoft is comfortable letting outsiders see their WinCE code, unlike most of their other products.

    But the law requires that businesses use reasonable common sense. If K-Mart suddenly got caught selling cocaine, they couldn't get off the hook by claiming that they thought they were selling convenient, individually wrapped flour packets.

  14. Several thoughts... on Woman Avoids $70,000 Online Gambling Debt · · Score: 1

    First of all, I don't think it's fair to look at this as a judgement in favor of the (grossly irresponsible) woman, rather than as a judgement against Visa. The money was only returned to her because Visa wasn't entitled to it, since they offered the loan illegally.

    And it was a loan. I can't think of any definition of "loan" that doesn't fit credit cards. I mean, credit cards, guys?!? You can't argue that Visa had no way of knowing that their loan was going towards gambling, either. They have a record of the transaction, they know this woman's address, and they are subject to the laws of California. So if it is in fact illegal to offer a loan for gambling in California, then Visa is legally responsible. I don't think they have a leg to stand on.

    That's one thing I'm not clear about, though... The article says only that the courts "frown on" loans for gambling. That's awfully vague. Is there a law on the books, or not?

    I'm certainly not defending this law. I think it's absurd, and I think you'd be hard pressed to find a /. reader who'd say otherwise. But absurd laws are still laws, and Visa definitely violated this one.

    This brings up an interesting chain of thought in my mind : could a game like EverQuest (a Massively Multiplayer Roleplaying Game) be developed by the OpenSource community, without people trying to take advantage of the fact that they could hack the rules of the game?
    On the face of it, I don't see why you couldn't just define the interface between your client and server in such a way as to prevent any deviation from the rules. If there is no me.make_invincible() message in the interface, then no amount of hacking the client can make it happen.

    In practice, this doesn't seem to be the way that it works... EverQuest in particular seems to do a lot of rule-processing on the client side, to reduce lag, although most of it is double-checked by the server once the network catches up.

    However, there's a bigger reason why massively multiplayer games won't be open source: Who pays for the servers? Sure, you could set up a company and charge subscription fees to access your server, even though the software is open. But so could I, and so could everyone else. Competition is nice, but it kind of defeats the purpose of a MMO game if it's hosted on 1000 different servers, each with ten people online at a time.
