  1. The state of timekeeping is...not pretty... at present, so an improvement would be nice; but it's somewhat hard to argue for something really radical when you could file down some of the really pointy bits by just keeping the deterministic parts of the current time/date setup, and ignoring leap seconds(which will eventually become an issue; but that'll take a least a couple of centuries, so it will be somebody else's problem.) UTC sucks, TIA FTW!

  2. Re:Why can't Microsoft do this? on Tiniest Linux COM Yet? · · Score: 1

    The more curious question is why Microsoft can't sell this. They were perfectly capable of putting together .NET Micro, which runs on fairly tiny stuff, and they've been poking at ambient embedded devices at least since SPOT and various DirectBand receiver devices. More recently, there was "Windows Sideshow", which more or less died without a whisper; but was a serious stab at making semi-autonomous devices, intermediate between ye olde serial LCD and the PDA/Phone/MP3 player that is just here to sync and then leave, work with full PCs in interesting ways.

    On the research side (and even further from commercial success, since as far as I know they never actually deployed it), they put together a proof-of-concept of using a small embedded processor to allow a PC to remain sleeping most of the time, while continuing to behave exactly as normal from the perspective of other devices on the network, by handing off tasks to the embedded device, which could then wake the host PC as needed to pass off results or respond to spikes in demand beyond its capabilities. (They never went beyond a demo, to my knowledge; but this seems like the sort of thing that could get very interesting if you took advantage of the CLR to allow a .NET application to move bits of itself between the host and the slave device, regardless of underlying architecture...)

    Back when they were still flogging warmed-over piles of DOS with a layer of GUI and instability, the big mystery was why Microsoft was so incompetent. What mystifies me now is how they manage to turn massive supplies of money and talent into such comparatively limited success outside of their traditional markets.

    The stated peaks for maximum luminous efficacy (in humans, this obviously varies, sometimes quite markedly, by species) are 555nm when things are well-lit enough for the cone cells to go to work, and 498nm under lower light conditions where it's just the rods doing the work.

  4. Re:That's pretty small. on Tiniest Linux COM Yet? · · Score: 2

    So small, there's no room for mounting holes, aside from the through-hole vias. Is that normal for COMs?

    The ones that expose a substantial number of I/Os often repurpose whatever flavor of DIMM or SODIMM socket is current at the time, since that's a well known, mass produced, connector that can handle the fairly touchy signal integrity demands of RAM and so is probably qualified for most assorted I/O stuff.

    If you don't go that route, the alternative for getting that small is usually some sort of terrifyingly fiddly fine-pitch Hirose connector(Gumstix COMs are good examples of doing this).

    Through-hole limits the number of lines you can break out; but is cheap and hobbyist friendly. Given that volume customers would probably just use the R5350 directly on their product's board, it's probably a fairly logical choice: if they make the board bigger, it becomes less useful for people who really need something compact, and (if you add the additional connectors, USB, ethernet, that the larger board would allow), starts to step on the toes of more powerful devices or re-purposed routers with their casings popped off; while, if they make it any smaller, they'd have to go with some fairly nasty, hobbyist-scaring, connector, at which point it'd just be a low-volume prototyping board for people who are going to go buy bare R5350s instead when production time comes.

    Wasn't the theory behind the Rise Of Embedded Java that companies would move between suppliers fairly rapidly (which they do) in order to keep BoM to a minimum and that those moves would involve disruptive changes of CPU architecture(which appears to be much more rarely the case) thus driving them to write as much as possible in Java for easy porting?

    As it is, ARM doesn't exactly appear to be, um, strongARMing, licensees on fees, at least if the fact that MIPS is more or less standing on a street corner and begging people to care about them, and SPARC might actually be easier to download and burn into an FPGA than it is to buy premade at this point. Doesn't mean that ports are free and fun, since all the exciting details of platform drivers and dysfunctional bootloaders and such haven't been hammered out; but sticking to a single CPU architecture for extended time appears to be easier and cheaper than ever.

    If you want the wired interfaces, and a little case, and need a PSU, because this isn't being integrated into something, it'll cost more.

    Hey, tell that to the manufacturers...

    For the moment, PC monitor is pretty much the compelling use case. There are a few pricey white-elephant 4k video sources; but not many. PCs, by contrast, just see a bigger monitor(barring a tediously long list of, sometimes GPU-vendor, even model, specific gotcha interactions with some of the hacks used by certain 4k displays to cope with the fact that none of the common interfaces are quite there yet for 4k, with Displayport, a monitor trying to use MST can get...interesting. With HDMI, I hope you like 30Hz, because them's the breaks, and I assume that EDID is total garbage, as ever). If you do comparatively lightweight stuff, even a modest GPU can probably drive it without incident. Gaming will require some serious punch; but anything remotely modern can run at the resolution it is told to, if you have the power.

    I don't deny that parents, among others, inculcate beliefs and values; but they certainly don't have a monopoly on that. In the specific case of non-procreation, I'm mostly just going on history: despite the obvious and dramatic handicap not breeding has on passing genes or ideas down to your children, culturally-sanctioned non-breeding breaks out from time to time all over the place, and often exhibits remarkable persistence.

    In some cases, (I don't know if this is coincidence, or whether some underlying factor is involved), like Catholic clergy and monastics in the west, the non-breeders even occupied a social position more or less specifically designated as "Teach beliefs and values to everybody".

    In other cases, it's more of a separation of labor thing: in the context of hereditary power being the default expectation (and frequent cause of messy wars) the use of eunuchs as a civil service class was a drastic, but logical, mechanism for ensuring that, unlike ordinary subordinates, you wouldn't have a constant problem with bits of your authority being taken and handed off to various people's sons.

    These days, there are fewer formalized niches for non-breeders(but also prophylactics that actually work quite well, so the celibacy requirement has been relaxed); but economic pressure (markedly longer delays to reach economic adulthood, employer preference for people who don't have family obligations, two-earner households) seems to be exerting substantial influence.

    My hope is for an equilibrium position that hands as much of the profit as possible to the writers, and the people who do the actual processing work (editing, typesetting, printing, systems administration, etc.) rather than rent-seeking gatekeepers; and I would be highly alarmed by developments that appear to be choking the production of books overall; but I'm much less excited about contract fights that don't appear to reach that level.

Just to get them to earth orbit (and I think this is the LEO figure, not geostationary) is north of $4,000/kg. Human transport to Mars is still a somewhat speculative number; but will certainly be substantially greater than that (and the traveller will consumer many more kg of food/oxygen/etc, so total cost will be higher still).

    Arguably they aren't like any other consumer good: they share a pretty easily identified, and salient, set of characteristics with certain other 'culture products', music, movies, and similar: marginal cost of production is essentially zero, different ones are partial substitutes for one another; but rather weakly compared to other consumer goods, 'brand' affinity follows individual producers (or nominal producers, as in the case of certain heavily-managed tween-pop-to-order acts) rather than companies, and so forth.

    Books aren't some Unique And Sacred Category Unto Themselves; but the characteristics listed above are pretty significantly unlike those of, say, consumer appliances(where marginal cost of production is comparatively high, different ones are nearly perfect substitutes, brand affinity, if any, follows companies while individual designers are unknown, etc.)

    What isn't clear to me (any authors in the house?) is whether the traditional big publishers are, by reason of a certain gentlemanly ossification, allies to the otherwise scattered and helotized writers, or whether this is basically a spat between two would-be-exploiters of authors over who gets the profits.

    Amazon sure as hell isn't in this out of the goodness of their hearts; but they are also not going to waste a penny more than necessary on quaint traditional supply chains, 'remaindered' or 'stripped' books, and anything of the like; but they also aren't going to let any mere customs hold them back when it comes to contractual matters.

    I'd be very, very, surprised to see a belief bred out of a population in a species with such (admittedly flawed at times) high levels of general-purpose cognition. Ideas move between hosts by quite different vectors than genes do, and (in most places, at many points in their history) the limiting factor for human population has not been fertility as much as it has been resources (not necessarily imminent Malthusian Starvationdrome!!!; but when a feudal society resorts to entail and primogeniture, or subdivision of inherited farmland starts to compromise the ability of an heir to actually raise a family on his chunk of Mom and Dad's Farm, that creates strong social upheaval that kicks in before people actually start starving to death.

    Among other strategies, some sort of socially-sanctioned mechanism for skimming off excess children(especially sons, having a bunch of edgy young adult males with limited odds of getting laid or inheriting anything running around is bad for stability). Sometimes you send them to the monastery. Sometimes you send them off to go raise hell in somebody else's country, and so on.

    This isn't universal, some situations are primarily fertility-bounded, and there is very little incentive, expect for really dislikeable specimens, to discourage anybody from procreating; but it's simply a matter of historical fact that various sorts of non-procreative roles (culturally sanctioned, sometimes even valorized) have existed for ages, and all that was back when not procreating meant celibacy, which hardly added to the idea's charm. I don't expect contemporary contraception to reduce the popularity of these roles.
