    I've heard the theory suggested that engineering knowledge(and accompanying social and technical organization) is exactly what allows a civilization to suddenly die out.

    Technology(speaking in the broad sense, including things like complex social structures, bureaucracies, and so forth) is extremely powerful; but also makes it fairly easy to get locked-in to brittle trajectories where(even if alternatives are theoretically possible), your only real approach to any problem becomes "do whatever it is we already do; but more, and harder". This often goes poorly. Worse, you have usually managed to build a population that depends on your complex social structures, which makes for a fun die-off if they should come loose.

    When the Roman legions stopped being a net gain, through plunder and Romanization, and started to become a liability(since they couldn't expand the borders any further, and spent most of their time fighting civil wars to install one emperor after another), Roman civilization as a whole never really came up with an alternative. They pretty much just raised more, tried harder, passed a few more laws to try to preserve the status quo. Long-view, they were following a doomed path, proximately, though, they didn't really have a whole lot of options. Any emperor who adopted a "fewer legions" policy would find himself replaced with extreme prejudice by somebody willing to do the opposite.

    I don't know how the Mayans went down; but complexity quite possibly helped them along.

    I doubt that it's the plumbing per se; but a rise in interlocking technical and social complexity really helps if you want to "go under" in a way dramatic enough for history to notice.

    Barring fairly rare events(like the sudden appearance of really nasty plagues, or an advanced culture showing up and gunning you down, or both), low-complexity cultures don't really "collapse" in any useful sense. They wax and wane a bit, some years good some years bad, and they may undergo various sorts of linguistic and genetic shifts due to warfare and migration; but they aren't specialized enough for things to really go to hell.

    If you have interlocking specialization, though, you have entire institutions, and populations, that are basically dependent on large numbers of other structures and people for their continued existence. This makes it fairly easy for the right push to, instead of "reducing the hunter-gatherer population by ~10%" do something more along the lines of "catastrophic mass starvation, entire cities abandoned to the flames, the capital investments of 200 years annihilated within months".

    PDF/A is indeed the sane specification(though it has a few friends for slightly different purposes; but offering similar levels of standardness and sanity).

    Trouble is, though, Adobe has very little incentive to stick to that(if some customer demands it, they obviously have an incentive to be able to emit sane PDF/A; but not much to stop there). Since the core, sane, bits of PDF are a royalty free standard, and Reader is free as in beer, Adobe only makes money if people buy the expensive versions of Acrobat, or heroically expensive "enterprise document workflow solutions" and so forth. Thus there are two pernicious forces at work: 1. If Adobe's de-facto PDF "standard" didn't keep sprouting tentacles of various sorts, it would be easier for competing products to reach parity, or "almost as good but a lot cheaper" status, and erode Adobe's profits. 2. Because Adobe's bread-and-butter involves worming their way into various horrible and convoluted enterprise document/form scenarios, their customers probably give them a lot of weird(and, outside of the customer's specific context, basically terrible) feature requests.

  8. Re:Umm? on Moore's Law Will Die Without GPUs · · Score: 2, Interesting

    Certainly, there are challenges to Moore's law, either fundamental physics or sheer manufacturing difficulty; but they have nothing to do with what the transistors are for(aside from modest differences if the issues have to do with manufacturing difficulties: If your 10nm process is plagued by high defect rates, it is probably easier to build SRAM, with tiny functional blocks, test for bad ones, encode the bad block addresses in a little onboard ROM, and have the motherboard BIOS do some remapping tricks to avoid using those than it is to build CPUs, with large functional blocks, and get pitiful yields).

    As for applications, there are definitely huge numbers of them that will see little or no benefit from more cores(either because their devs are lazy/incompetent, or because customers won't pay enough for them to justify the greater costs of dealing with hairy parallelism bugs, or because they depend on algorithms that are fundamentally linear). However, because of servers and virtualization, the demand for more cores should continue unabated on the high end for as long as vendors are able to deliver. If your enterprise has tens or hundreds of thousands of distinct processes, or tens of thousands of distinct VMs, you already posses a crude sort of parallelism, even if every single one of those is dumb as a rock and can only make use of a single core.

  9. Umm? on Moore's Law Will Die Without GPUs · · Score: 5, Insightful

    Obviously "NVIDIA's Chief Scientist" is going to say something about the epochal importance of GPUs; but WTF?

    Moore's law, depending on the exact formulation you go with, posits either that transistor density will double roughly every two years or that density at minimum cost/transistor increases at roughly that rate.

    It is pretty much exclusively a prediction concerning IC fabrication(a business that NVIDIA isn't even in, TSMC handles all of their actual fabbing), without any reference to what those transistors are used for.

    Now, it is true that, unless parallel processing can be made to work usefully on a general basis, Moore's law will stop implying more powerful chips, and just start implying cheaper ones(since, if the limits of effective parallel processing mean that you get basically no performance improvements going from X billion transistors to 2X billion transistors, Moore's law will continue; but instead of shipping faster chips each generation, vendors will just ship smaller, cheaper ones).

    In the case of servers, of course, the amount of cleverness and fundamental CS development needed to make parallelism work is substantially lower, since, if you have an outfit with 10,000 apache instances, or 5,000 VMs or something, they will always be happy to have more cores per chip, since that means more apache instances for VMs per chip, which means fewer servers(or the same number of single/dual socket servers instead of much more expensive quad/octal socket servers) even if each instance/VM uses no parallelism at all, and just sits at one core = one instance.

  13. Re:Please refrain from pedophile jokes... on Church Turns To Facebook To Find Priests · · Score: 1

    It isn't the pedophilia per se(which, while tragic, is expected at a certain level in any situation where an adult population has the opportunity to interact with children), it's the institution-wide, endemic coverup and enabling of that pedophilia that (rightly) makes the catholic church a target of derision.

    Some percentage of priests are going to be pedophiles, inevitably, because some percentage of adult males are. However, that doesn't mean that you deliberately conceal them from law enforcement as part of some bullshit assertion that canon law takes precedence over secular law. Nor does it mean that you deliberately circulate the problem priests around, to provide them with fresh victims and, cynically, give them assignments where they are likely to have access to the weakest and most vulnerable, and least likely to be able to cause a scandal, targets...

    Now, incidentally, I strongly suspect that priests are more likely than the population at large to exhibit sexual preferences that would displease orthodox catholic teaching on the subject(though, not all of which are, by any means, of legal or ethical concern. Homosexuals who prefer consenting adult partners make the church sad; but are neither legally nor ethically a problem). The logic of my suspicion can be understood by the following analogy:

    It is highly likely that, on average, priests as a population have either less interest in money, or less of a belief that they would be able to obtain it, than otherwise demographically equivalent people. The reasons are fairly simple: Priesthood doesn't pay all that well, given the amount of training and effort it requires. Thus, anyone who becomes a priest is either super-gung-ho about priesthood, doesn't care much about money and what it can buy, or doesn't think that they could earn much money elsewhere(making the opportunity cost low), or some combination of the above.

    Priesthood imposes a "sexual opportunity cost" similar to its monetary one. Thus, one would follow similar logic and expect that priests are either more gung-ho about priesthood than non priests, less interested in sex generally(just lower libido) than non priests, or have sexual preferences that they (as catholics conservative enough to consider priesthood) could not have satisfied even without a vow of celibacy(thus making the opportunity cost of a vow of celibacy low). If you would just love to marry a nice catholic girl and have a bunch of kids, a vow of celibacy is a serious cost. If you are gay, or polyamorous, or a pedophile, or otherwise of unapproved taste, you cannot licitly(within catholic teachings) have the sex that you want in any case, so a vow of celibacy is a minimal cost.

    Since humans are way better at deciding to resist temptation in the future than they are at resisting temptation in the present, this more or less ensures that a fair few sexually atypical individuals will end up in the priesthood, under the optimistic impression that they will remain celibate. Now, again, many of them are both legally and ethically unproblematic to society at large. A priest is having an affair, homo or heterosexual? Not our problem. Some of them are legally clear; but ethically dodgy(your classic "father confessor 'counseling' wives looking for advice about their marriages" situation. All legal, consenting adults and so forth; but pretty clear abuse of position). And then you have the pedos and the rapists, for whom the church has been disturbingly willing to cover.

However, that (quite simple) function is also a huge driver of Flash installation. Basically, if you want to watch video on the web, you need to install Flash. Once you have flash, you bolster Adobe's install base stats, serve as a target for much more sophisticated Flash-based applications, and bolster Adobe's efforts(through AIR) and similar to have a quasi-unified webapp/desktop-app runtime based on Flash and their various content creation tools.

    Microsoft has its own, competing quasi-unifed webapp/desktop-app runtime, based on .net, winforms, and the like. Unlike AIR, it much more closely ties the user to Microsoft, and Microsoft platforms and technologies. Therefore, they want to destroy AIR and Flash.

    By indicating support for HTML5, which will support the relatively trivial video use cases(youtube style stuff, without Serious DRM mandated by paranoid content providers), they substantially reduce the motivation of users to download Flash and corporate IT departments to install and support it. Since Silverlight comes by default in newer MS OSes, they get increased marketshare vs. Flash/AIR.

    Since HTML5 makes possible advanced web applications, but still lags in easy tools vs. Flash or Silverlight(which won't stop Google and their ilk; but will stop Joe Flash Monkey, or Bob corporate intranet developer), HTML5 can be safely supported without destroying Silverlight.
