    Yes, flying is better understood with math, it's a physical problem. I wasn't implying that no explanation at all is better than any model, I was refering to verbal explanation, like when you talk with a best friend, and if he is one of those guys that have a clear understanding of life and you, he'll be able to tell the REAL problem based on the behaveour.

    You are missing something, to have an econometric model the right way, you must first have a teory. if you do not have a theory you can't use econometrics to prove or disprove your theory. Steps for an econometric model:

    - Present your theory or thesis
    - Present the stochastic econmetric model you'll use to test it's validity
    - Estimate coefficients
    - Accept or reject your hipotesis (or refine your theory and go pack to the beggining)
    - Predict

    It has been proved that you make relly great but meaningless econometric models. Like average lenght of women dresses and (can't remember well, but it was something funny) the stock market. I think the correlation was significnt at 99% confidence level... :)

  5. Re:Psychohistory was terrible science on The First Steps Towards Asimov's Psychohistory? · · Score: 2, Informative

    Nobody cares about averages here, you are supposed to predict the future, as in the order in which the coins will land as time passes. If you miss the order the results will vary to a great degree.

    In other words, you could easily predict the NEXT coin flip (i keep on using the coin flip, but i am thinking on the physchohistory of humankind, so this experiments are NOT radom as in a normal coin flip) with near 100% accuracy. But you cannot predict the 10000 coin flip, because to predict that coin flip you'll need to know the exact flips that came before and in what order.

    I think I made a short explanation long, but the point is the original poster does know that statistics work, but NOT so well when future predictions depend on the accuracy of all past predictions. Errors do get accumulated as any time series analist (or any econometrician) will tell you... prediction does lose accuracy as you get further away from "present time"...

    I'd say phychohistory would be possible if and only if ALL individual acctions and all physical fenomens could be traced, and we'd be talking just about physical on a grand scale. We'dd be just attoms in deterministic paths...

  6. I will say it only once... on The First Steps Towards Asimov's Psychohistory? · · Score: 4, Insightful

    For any conceibable behaveour there is a mathematical way of fitting the behaveour with a certain degree of probability. If something is not pure noise, then there must be some way to formalize it, though language itself or in mathematical notation.

    This works, of course, don't add much value because they never explain how or why things are like that. With physics you don't have to explain the basic laws, they "just are", but with everything else, you better have some explanation of some sort because, in reallity, they are nothing more than constructs based on physical constraints.

    On the other side, it might be funny to see how some people could see these formalizations as expressing more or being more accurate than "plain verb" explanation. "If it's hard to understand then it's real science!!" (wrong!)...

    Just my thoughts so (I am biased yes, I've seen to many quantitative economics to believe equations express more just because the math is hard...they usually don't).

    I think it's a great solution, in the variants you described, or being removable (a connector problem, not an HD problem) or being for buffering or standalone if you need extra storage (say 60 GB). In any case, you could have all three options (one internal fixed, a slot for removable variant and a firewire port & mode that activates buffering.

    A plain non-removable big HD consumes a lot and is ugly, and solid state fash cards are really unnecesarily expensive. Of course, who cares, some people will still think they need the solid state solution :)

    It's supposed to be a temporary solution. It being temporary depends on Linux taking off in, among many other markets, the games market. So you need to WineX for linux to take off, and you need Linux to take off before ports start to make sense. It's a double blade knife yes, it could well be the case that games never get ported to Linux, but that is not intrinsic to your reasoning, it depends on other things. For instance, if we get to a point where it's easier to develop under Linux, then having a Linux port will make sense economically. If it never makes sense quility wise and specially, economically, all hope is lost.

  19. One word: competition.... on Corporations Suffer Microsoft Activation Bug · · Score: 1

They don't care spending more money for things that are "supposed" to be profesionally built and supported.

    Of course, the problem is one of non-innovation and superficial analysis. But hey, not many people got fired by not using open source, and surelly a lof of people did got fired because of that. People have prejudices and a carreer to take care, not to mention kids to feed. That's part of the equation too...

    But things gradually change. As long as OSS becomes more and more usefull, early adopters that are wise enough to have a bussines plan that focuses on a real need will reap the rewards. Ofter a while, it will be everyone, but I think we'll have to way a decade or more...

  24. Re:what do you expect on Are Printers What They Used To Be? · · Score: 1

    Personally, I think that they should simply sell the printers without ink (and that it should be mandated). The printer manufacturers would probably love this, as it would let their revenue stream be the ink.

    No, what we need is somewhat the opposite. If their revenue stream is the ink we are fucked, because then all their strategies comes down to trying to change catridge format and circuitry so that no other ink runs reliably with them. And it allows each munufacturer to NOT compete in the "already sold" market (the ink market is somewhat static given an initial market share).

    So, in brief, what we need is to SEPARATE the ink and printer market. If we do that, well be charged what printers cost (expensive printer always better than cheapo ones) and what ink costs (expensive inks and cartridges). Standard sizes and connetors for ink cartridges would be the goal.

    In that fashion, printers manufacturers should me mandated to follow certain rules for allowing third parties to produce geniune legal and quality catridges.
