  4. Re:Got Rice? on The Future of MREs · · Score: 1

    Rice is a low protein food, and, more importantly, doesn't contain the full set of proteins the body needs. 30 servings of rice per day won't sustain your health nearly as well as 10 servings of rice and 10 servings of legumes, nuts, or meat, especially if you're doing anything physical. Also, rice is not particularly dense in vitamins, and, again, does not provide the body with a full set.

I love code cleanup, but I know my limits. I realize the sprintf density may vary from field to field, but hearing the number 5000 will make most people think twice.

    No, it wouldn't. If your C code used sprintf 5000 times, you would find plenty of places where buf is passed in as an argument so that 'n' is not locally known. Rewriting 5000 instances of sprintf and then testing the code paths in a program that used sprintf 5000 times sounds like a big job for little gain. Most sprintf instances are not potential buffer overflows, and there are plenty of other dangerous functions to worry about.

  15. Re:Probability ... on Grok Goldbach, Grab Gold · · Score: 1

    You probably realize that your conclusion is too weak. The probability of finding a counterexample beyond 10^15 decreases so rapidly for every number searched that given a "random" distribution you will not, with almost complete certainty, _ever_ find a counterexample beyond 10^15.

    Asymptotically, your probability is e^(-2n/(log n)/(log n)). The chance of finding a counterexample beyond 10^15 is less than the limit as (N -> infinity) of the integral from (10^15 to N) of e^(-2x/(log x)/(log x)) dx. Since this is hard to integrate, take a simple function that dominates it beyond 10^15, such as:

    10^(-4 * 10^11) * (e^(-sqrt(x))) * 2 * 10^7.5) / e^(-10^7.5) / ( 2 * sqrt(x)).

    The integral of this for x between 10^15 and infinity, if my scribblings are correct, is 10^(-4*10^11) * 2 * 10^7.5 = 10^(-3.99999999992 * 10^11). In other words, the odds are worse than 10^(100000000000) to 1 against finding a counterexample beyond 10^15 (or beyond 10^11, for that matter).

    Without boycotts and media muck-raking, corporations are, indeed, obligated to perform whatever atrocities are necessary in order to maximize profit and future profit for their shareholders. This is why it is extremely important that we continue the boycott en masse. It is one of the few ways that we can collectively speak out against behavior that we see as wrong. This is why some of us boycotted companies like Nike or Nestle who caused suffering in the third world. If you feel a company is acting irresponsibly, you must avoid its products.

    Of course, there is more than just negative reinforcement. I am protesting the present computer patent law system; I have no real grudge against Amazon. If Bezos promptly does the right thing, I will not only resume buying from Amazon, but I will visit their site even more frequently, to more than make up for my current boycott.

    You're not making sense.

    If you're a fan of Microsoft, then sure, the rebate might not be worth it. But if you dislike Microsoft, Office Max, and Packard Bell equally, then you might as well take advantage of it. Say you spend $421.95 for MSN plus a $400 computer that costs $200 in parts and labor, and get a $400 rebate. You are getting a computer that costs (Microsoft + Office Max + Packard Bell) $200 for $21.95. The trio, as a group, is losing $178.05. How the money changes hands within this group is not your responsibility.

    Besides, super-rebates like this are the essence of marketing hype. As long as this tactic is profitable, big companies with deep pockets will have a huge advantages over smaller companies who may have more quality products. One way to discourage this practice is to take a bite out of the profits of the tactic by using loopholes like this. If you care about quality products, taking advantage of this promotion is a moral imperative. Do give your money to people like this, please.

    On the other hand, wouldn't you say that the lack of a published CI in the article is somewhat telling? You would expect that a good scientific magazine would print a 98 or a 99 if it occurred, right?

    The SD for the difference of the means in an 8 vs. 8 test would be approximately half the SD of the standard population's SD, but large CI's ranges for the test will be increasingly greater than half of the same CI for the population because we are dealing with a T-distribution. It will take more than 2.5 SD's for a 99% CI. But you're right; we're just guessing here.

    Another question one might ask is, how many similar tests have been run with no good results, and also, how many similar, plausible correlations were being looked for in the same test? So we may have gotten a 98% likelihood of significance. What if we were measuring 5 variables, any one of which might have independently shown significance but didn't? What if 10 similar tests have been tried by other teams around the world, none of which reported any good results? That's 50 measurements, and it's quite plausible for the null-hypothesis to randomly generate a 98% once in 50 attempts.

    Whatever the statistics come up with, the results will need to be reproduced in order to establish validity. I'd guess that securing further grant money is a primary reason for the press release.

This mentality is prevalent among the young (pre-high school), especially if they have been not been exposed to other races or cultures yet.

  23. Re:SETI@Home... on SETI@Home Says Client 'Upgrades' Are a Bad Idea · · Score: 2

    I have a graduate degree in mathematics, a background in numerical analysis, and I've worked as a programmer and scientist for years in a quantitative science department. Let me pose a random scientific-programming example so that non-scientists can have something to chew on.

    Suppose you want to maximize a function of n variables, where the function is too difficult to differentiate (usually much too difficult). You have transformed these variables to be as nice as possible. Basically, to find the maximum, you will begin a search at some predefined point in n-space (or k predefined points, doing k separate runs). You iteratively attempt to increase the function's value at these points. In each iteration, you might take small pertubations in each direction to try to estimate a gradient. After determining the local topography, you then move your point in that direction, taking a small step, a large step, or maybe a random jump, depending on previous movements or the state of your algorithm. In the end, you will arrive at a local maximum, an inflection, or a boundary. You hope that this is the true maximum for your domain, but the best you can hope for is a heuristic solution.

    This sort of problem, depending on the function topography, tends to be very ... fragile. If you modify your methodology, changing the step sizes or the state criteria, for instance, you will probably change the final local maximum, and then your results will be unreproducible, and much of your statistic analysis goes out the window. Worse, you don't even have to touch the methodology. Change the order of seemingly commutative arithmetic operations and your LHS differs slightly due to different roundoff errors, which (in 64-bits, but probably in 80-bits, too) all too often results in a different local maximum, even for problems that aren't particularly ill-conditioned.

    While many tweakers will be careful to leave mathematical algorithms intact, many others just won't think about this sort of thing, and will poison any data pools their results are aggregated into.

    This said, let me say that there are a _lot_ of scientists who are truly bad programmers, and all too often these people think they are hot stuff. They write brittle, monolithic, error-ridden pieces of garbage that are just painful to apprehend, with plenty of hidden bugs just sitting there. Ugh. An acid test to weed these people out might be, "What do you think of _Numerical Recipes in C_?" If you come from a scientific background and want a good programming job, I think you have to prove yourself, since industry is well-aware of the Numerical Recipes scientist archetype.

    Chances are, the SETI code is at least somewhat ugly, and can really be improved for future releases by open source. NO modifications should be made on an ongoing experiment, but that doesn't rule out an open source next version, with the active communtity serving as alpha/beta testers. There is a lot of interest and a lot of talent out here. All it takes is some openness and sme good management on SETI's part, right?

    And really you're targeting Washington State legislators' integrity based on your own contempt for Microsoft. Face it, every state has its share of conservative representatives who cater to large businesses. Representing one's constituency is part of a congressman's job, and if M$ gets special attention due to its economic effects, it is justified by the number of people who are employed directly or indirectly by the company. The political climate of the area seems to me to be pretty homogeneous.

    To take a particularly conservative example, Senator Slade Gorton doesn't just represent M$ over its competitors, he also represents Boeing over their competitors, logging and farming over and enviromental interests, state fishing over tribal interests. Basically, he's a right-wing fucker; my point is that he's a right-wing fucker across the board, not just a right-wing Microsoft fucker (fuckee?). When it comes down to it, he gets things done for Washington State, and I suppose that's why he continues to win elections.

    Don't think that the congressmen around the country who go after Microsoft are doing so because they care about quality software.

  25. I assume your employer will need HIPAA-compliance on Username/Password - Is It Still Secure? · · Score: 1

    As stated, I believe that a secondary means of authentication is legally required by personnel when transmitting sensitive information. This can be keycard, biometrics, or whatever. The HIPAA requirements will be very gradually enforced, in order to give health organizations time to tackle the often massive changes needed to make their systems HIPAA-compliant.

    Regarding someone's remark about sending biometric information unencrypted: That would definitely be a stupid use of biometrics; sending authentication information in the clear is a violation of HIPAA standards. Biometrics does not obviate the need for a basic encryption infrastructure, whether it is built on PKI, Kerb V, or whatever. It would probably be a secondary mechanism on top of cards or passwords, with information sent only after symmetric-encryption communication has been established. I don't think biometrics can be used as a sole means of authentication.

    Some of my coworkers were examining the encrypted E-mail problem for a more managable set of users -- medical personnel only, for several hospitals. One law, I think also part of HIPAA, states that the IS departments cannot manage be the central key authorities; these have to be run by a third party. We looked at PGP, and we looked at the SMIME variants. The latter, IIRC, suffers from from a recent Netscape/Microsoft implementation divergence making the one's keys incompatible with the other's (how surprising!). I think it was a hassle finding a vendor who wanted to manage PGP private keys for our heterogeneous systems (different browsers, several different platforms). Then you have the doctors to deal with, who do not take kindly to any added complexity to the system, no matter how minor. It is difficult to force them to use a new tool that provides no perceptible benefit to them.

    You should definitely make sure that you know precisely what the legal requirements of your company are, and approximately when these requirements will be enforced. Make them aware of the laws and they will be more responsive to your proposals.
