    yeah, and they can't spend massive resources developing estimates for every configuration of hardware in the universe.

    beyond that, the kalman filter's assumptions are really not tenable for this application, even those of the advanced variants. particularly, the process isn't stationary, and the noise terms are not independent. more basic statistics can do just as well; it's really a matter of it not being worth the trouble.

    many of them should ``go backwards'' all the time, as would any half-way honest estimate without an oracle; the installer found a special case and has to run another code branch to replace something that's already been done; download drivers; etc.

    it's just that the ui element won't update for it. no progress bar shows ``actual progress''; they all show percentage to completion. these are slightly different.

    at any rate, the majority of vitamins present in most commercial fruit juices have been added, and are mostly artificial.

    why should i pay for someone to `fortify' my juice with a dime's worth of multivitamin? juice=sugar, and mostly fructose (=`fruit sugar') if that concerns you (it doesn't me).

    if the author is in fact a new yorker, he may have been influenced by some self-congratulatory advertisements the mta put up in the subway a few years ago, implying exactly that their new regenerative braking systems supply a net gain.

  6. a silly logic puzzle, or just flawed writing? on Missouri Legislation Redefines Science, Pushes Intelligent Design · · Score: 2

    1: 'If scientific theory concerning biological origin is taught in a course of study, biological evolution and biological intelligent design shall be taught.'

    2: 'If biological intelligent design is taught, any proposed identity of the intelligence responsible for earth's biology shall be verifiable by present-day observation or experimentation.'

    well, since the second condition is impossible to meet, and is a necessary condition to satisfy the first, it means only that scientific theory concerning biological origin cannot be taught in a course of study. (contrapositive)

    so... does that just mean you can't teach abiogenesis? that is what `origin' means in this context, right? evolution is okay to teach, and doesn't trigger the latter necessary conditions, even though they mention ``biological evolution,'' apparently as a red herring.

    wait. did they mean for this to be a silly logic puzzle, or are they just too stupid to realize what they're saying?

    apples don't have vitamin c naturally, and in fact not much of any vitamin. any vitamins in apple juice have been added.

    no, you don't understand. this is ron paul we're talking about. since ron paul is, by definition, opposed to everything bad and in support of everything good, there must instead be a problem with semantics.

    ah yes, there it is! sure it says ``trademark,'' which literally refers to a registered device for identifying products or services, but what it really means is the totality of someone's likeness, which is the most private of properties because it recapitulates one's own intellect and character!

    phew. glad we resolved that! it's just like the case of those racist newsletters. sure, it looked like either ron paul was aware of it, or was a total idiot who didn't know what his campaign was doing in his own name, but then he cleared it up for us: racism is a form of collectivism, so obviously it would have been impossible for ron paul to have anything to do with it. it follows logically, don'tcha know.

    there are fallacies apart from deductive logical fallacies. if someone offers a prescriptive moral system, it seems reasonable to evaluate it by whether its adherents can follow the system consistently. for example, let's consider the prescription of catholic priests not marrying. sure, it makes sense; no wife means closer to god (if `god' is uncomfortable to you, replace it with `studies' or `devotion'). great, except now they sodomize little boys. there's no logical fallacy there, but it does suggest that the moral system is inadequate in the face of human nature.

    it would be quite easy for me to devise a perfectly logical way of life, which is nonetheless too strenuous or silly for 99%+ or even 100% of the population to obey. further, if, in fact, the system i develop is too difficult for me to adhere to, it does suggest that it's not very realistic to expect anyone else to.

    uh, yeah; since i've justified it about a dozen times, it's certainly a conscious decision by now even if it wasn't when i started, which it was.

    so, once again: the purpose is to emphasize that web forums, like slashdot, are more like chatting than they are like formal writing. in conversation, there is no capitalization. i don't want anything i write here to be taken as an authoritative written statement, so i demarcate by using a pseudonym and not capitalizing.

    though, i've got to admit, i'm getting tired of being slagged over this issue. just keep it up and i might capitulate.

    i agree in part, but really it's a matter of whether your supposed cleverness is actually very predictable, as happened to Feynman's boss. it's really psychology more than it is entropy.

    some people think leetspeak is good enough for obfuscation; they were right a few years ago, but not anymore. extrapolating, it's a bit silly to think that simple padding methods such as the one you stated will never be added to the cracking strategies.

    i'm skeptical about the spelling and grammar checker, but as for the pressure...

    pens have already been developed which don't require noticeable pressure in the first place.

    there are even some for children.

    aren't they messy? not if you use cartridges. also, blue fountain pen ink is usually easily washable, unless you specifically get a variety which isn't.

    won't the dumb kid lose his $20 fountain pen? well, i guess this might be a problem (although somehow we managed before), but i'm sure this accelerometer/vibrator pen would cost a lot more anyway.

    the ergonomics are another advantage. making the pen easier to hold can only improve handwriting.
