    I'd say 1) is a perfect time to mention even a broken clock is right two times a day.

    Argh. A stopped clock is right twice a day, assuming it's a conventional 12-hour clock.

    A broken clock can be wrong all the time. For example, assuming a 12-hour dial clock, consider if both hands have come loose and are now pointing directly at the 6. That is not a valid representation of 12-hour time. For any given position of the hour hand, there is one and only one correct position of the minute hand.

    The minute hand does not carry any addition information - it's simply helpful for obtaining a more-precise reading over a relatively imprecise analog channel (called "glancing at the clock").

    Really, it's like some of the people who post here don't even care about technical specifications.

  2. Some folks eat quinoa and twigs and still have risky acid reflux

    Indeed. I have relatives in this position, more or less - careful attention to diet and regular exercise, but still chronic reflux. It's not always "lifestyle".

    I, on the other hand, am somewhat less careful about diet (though I do eat a wide variety and probably hit all of the nutritional targets that have any actual evidence behind them), and while I do exercise it's decidedly irregular, but my weight and waist size haven't changed in a couple of decades and I don't think I've ever had so much as heartburn. Maybe it's genetics and epigenetics, maybe there's a microbiomic contribution ... but it's not because I lead some ideal lifestyle. Just luck of the draw.

  3. Writing is not for everyone and not everyone will gain even a modest benefit from learning [to write]. Furthermore this is shit that is better left to nobility.

    At what historical moment was literacy the province of the nobility? I can't think of a historical culture where it wasn't either widespread (a modern phenomenon[1]) or largely confined to a clerical class. Who were most assuredly not "the nobility".

    Your claim about mathematics is pretty specious too. While mathematical learning has a complex history in any culture I can think of, I can't think of a single historical instance where that particular claim was the dominant ideological stance on it.

    Of course your overall argument is a pretty weak argument by analogy, even if we accept these claims. And as far as I can see, more people here are arguing that basic coding should be part of the required curriculum, just not a substitute for learning a natural language.

  4. moral hazard on Are Gates, Musk Being 'Too Aggressive' With AI Concerns? (xconomy.com) · · Score: 1

    I'm mystified by the idea that a horizon of as short as 30 years for massive job loss doesn't count as a pressing problem.

    But ahead of that (and far ahead of the hand-wringing over GAI as existential threat), I'm concerned about the moral hazard presented by the increasing delegation of ethical choice to machines. That's happening now, indeed has been for a while, and products like autonomous cars will expand it greatly.

    Delegating ethical choice is popular. Making ethical choices is expensive, both in terms of cognitive load and because they often involve deciding against immediate personal benefit.[1] And they're psychologically unpleasant, particularly when all the options have negative consequences (as in the Trolley Experiment) or where the decider can't find a Nash equilibrium.[2] So there are strong economic incentives to make those delegations.

    And that has a number of unfortunate consequences. It erodes one of our most important functions as thinking creatures. By reducing opportunities to make such decisions in small matters, it eliminates a critical paideia that trains us in making them for momentous ones. It contributes to the gradual conversion of industrial society into an algorithmic Babylonian Lottery, where fewer and fewer people have any insight into how decisions are actually made.

    More leisure time? Sounds like lotus-eating, if you ask me. A lot of people doing little of consequence and avoiding anything difficult.

    [1] Assuming you make the choices that are generally preferred by a well-socialized majority in an environment of relative surplus. Antisocial behavior disorders, poor socialization, and resource scarcity all tend to influence ethical decisions toward selfish and anti-social ("I will pay to hurt you") options.

    [2] Note Nash's Existence Theorem does not include all possible games. More importantly, real-world conflicts aren't always isomorphic to games where the players can find Nash equilibria, either because they're equivalent to a game that formally does not, or because not enough information is available to the players.

    Dijkstra first used the phrase "GOTO considered harmful" in 1968

    Not even then, actually. The title of the letter, as published in CACM, is "Go To Statement Considered Harmful"; and that title was added by the editor. I just skimmed through it again, and unless I missed it, he never even uses the word "harmful".

    He does say that "go to" (boldface in the original) is "too primitive", and refers to its "undesirability" and "disastrous effects" and "(logical) superfluousness".[1]

    But the passive construction "considered harmful" is, just as its most natural interpretation would have it, an indication that someone other than the writer considers it harmful. That someone was Dijkstra; and while he cites others in support of his position, it would have been rather unlike him to step back and crouch behind the passive voice. The man was a first-order curmudgeon, bless 'im.

    How about we say that mathematics is accessible to "Anyone that has the intellectual facilities to master a spoken language" and who really tries?

    That's still rubbish, without qualifying "mathematics" much more narrowly.

    I'm pretty good with mathematics. I have a CS degree (among others). I was doing multiplication in preschool, calculus and recreational mathematics (some topology, number theory, that sort of thing) in high school. In college I did linear algebra, discrete mathematics including predicate calculus and group theory, lambda calculus, statistics - all the usual suspects. On my own I've worked through such things as category theory and algorithmic information theory. I've developed algorithms that required mathematical proofs. I regularly read academic papers with significant mathematical content.

    But it doesn't take me long to find mathematical problems and discussions that force me to study them carefully and work through them on paper, and sometimes look up explanations, to understand them. That's true even in treatments intended for lay readers. Right now I'm working my way through Smullyan's Forever Undecided, which develops the Incompleteness Theorem using doxastic logic, and, man, it seems like every page I have to read paragraphs multiple times and try out degenerate cases on paper before I get what he's saying. Even for something simple like continued fractions I need to be feeling pretty alert and focused, or it just doesn't click.

    I have a much easier time with mathematics than most of the people I personally know, but I have a few friends who are professional mathematicians (in academia or industry), and they fly circles around me. Simply much, much, much faster at picking up new formalizations and grasping their consequences.

    There are vast realms of mathematics ("known" mathematics, for the Realists in the audience) which aren't accessible to me. It'd take me decades to learn an appreciable fraction of them. Some of them I probably can never understand, regardless of how much effort I put into it - and I'm good at that sort of effort. I'm a knowledge worker, after all, and I've earned multiple college degrees, in disparate subjects.

    So claiming that some straightforward qualification indicates a person can "do" math is vacuous. It says nothing useful, because "mathematics" is a tremendously large domain of study (basically the study of all constructions which can be formed by extending some set of axioms using formal productions), and because that domain requires increasing intellectual capabilities as it expands. It might be true that anyone who can learn a natural language can learn arithmetic (though I wouldn't be shocked to learn of a counterexample); it might even be true that any such person can learn basic algebra of real numbers (though that's more dubious). But "mathematics" at large is accessible to only a small fraction of the population.

    (And, of course, most of mathematics in a strict sense isn't accessible to anyone, because most of it is incompressible and large. Chaitin proved that thirty years ago.)

Sure, Facebook and the like can get by with never-consistent kill-them-all-sort-them-later distributed farms of commodity PCs, but there are still some businesses which need a modicum of reliability in their data processing.

    There are probably on the order of 10000 System z installations. Yes, that's a small number relative to x64, but it's still very much "mainstream", particularly when you look at how they're used.

    In practice, System z machines these days are pretty much all running a bare-metal hypervisor (derived from IBM's VM OS, which was the first commercial virtual-machine OS) hosting various "LPARs" (logical partitions, i.e. virtual machines). The OSes in those LPARs - which may be zOS, zLinux, z/VM, z/VSE, TPF, and possibly others - will be "IPL'd" (rebooted) frequently or infrequently, to handle those configuration changes and patches that require it, depending on how the organization likes to schedule such things. The hardware itself and the hypervisor are likely to stay up for years at a time. Hardware upgrades are probably the most common reason for a hardware shutdown.

    That said, z isn't a completely fault-tolerant architecture like Stratus or Tandem (now part of HPE). There are various fault-tolerant options for z machines, but I'm not aware of any configuration that's like Stratus' "open the cabinet and yank out a CPU card" level of tolerance.

  16. If a placebo works, does it become a medicine?

    Not as such, because the placebo effect, by definition, can't depend on the particular placebo administered.

    Instead, if there's a consistent, statistically significant placebo effect for a given condition, we can say that administering a placebo is an effective treatment (to some extent) for that condition.[1] So placebo X doesn't itself get promoted to medicine, but placebos in general can have medicinal effect.

    Of course this means that "alternative" treatments, including magic water, can act as medicine. But the effect has nothing to do with the supernatural or nonsensical theories offered by practitioners,[2] and is usually highly patient-specific, unpredictable, and not very productive (i.e. it usually has little useful effect in terms of prolonging or improving life).

    There's a large body of work on the epistemology of empirical science in general and of medicine in particular. While most of that falls under philosophy, and the rest is in effect meta-science (i.e. how to conduct science so that it's scientific), much of it is actually quite rigorous. Questions like yours have received a good deal of attention. Sometimes the purveyors of pseudoscience like to pretend that these sorts of questions undermine scientific epistemology, but they're just displaying their own ignorance, or being disingenuous.

    [1] Or, more likely, for one or more of its symptoms; if the condition isn't purely psychosomatic, the placebo effect is probably only symptomatic. Of course, we know that for many physical ailments the patient's quality of life and state of mind can have a significant effect on the body's immune response and other healing factors, so sometimes that will have positive effects on the underlying cause as well. To the extent that such effects are measurable in a methodologically-sound manner, they fall under the aegis of scientific medicine as well.

    [2] Or more precisely, those theories have no real explanatory or predictive power, and no advantage over random explanations. And since the epistemological protocols used to concoct them (making shit up and telling a story about it that's attractive to some audience) are arbitrary, they lack confirmability as well.

  17. Ok, so let's continue with that logic. If someone first jabs them with a pin then they will have no problem with someone stabbing them with a knife because they've been "inoculated" against stabbing.

    In the US, you can do your own lead-paint abatement. You can install a home generator and transfer switch. You can put in an in-ground (or in-home) heated pool.

Never roofed one, or done major excavation, but that's about all that comes to mind.

(Half the circuits running into the electrical panel in this house don't have entrance clamps. The upstairs bathroom's sink drain line was unvented. And so on.)

    In any case, DARE[1] shows some regional use of "learnt" in the US, and I dare say[2] that you'd have a difficult time demonstrating that every such use was by someone who is "poorly educated" by any reasonable standard.

    Certainly use of the -t suffix has been declining on this continent for more than a century, though in English as a whole the trend is not so clear. And it's not just the past-tense inflection of verbs, as the rarity of "whilst" in this country shows.[3]

    [2] Heh.

    [3] Etymologically "whilst" is "whiles" + -t, where -t is still in effect a suffix indicating the past tense. But "whilst", a synonym for "while", is pretty much always used grammatically an adverb, even if etymologically it's the simple past tense of "to while" (as in "while away the time"). All this thanks to the eagerness with which English users move words among parts of speech.

    Amen to that. In my experience, the biggest problems with C++ are the vast amount of poor old code, and the large number of C++ programmers who are still using the constructs that were necessary before C++98 - often mixed and matched with newer approaches, so large codebases get increasingly stovepiped.
