  1. Re:Init alternatives on Devuan's Systemd-Free Linux Hits Beta 2 (theregister.co.uk) · · Score: 3, Insightful

    The biggest improvement over antique boot systems ...

    That there is the heart of the problem, an attitude that anything old is necessarily bad. That your otherwise calm and reasoned presentation allowed this pejorative to slip in belies the psychological bias that underlies the wide arguments on the subject.

    Lest we forget, Linux as a whole turned 25 recently. That's antique. Are you giving up the entirety because it's old? Your favorite editor is probably (just based on popularity) is either emacs or vi / vim. They are very, very old (heck, I've been using emacs since the early 1980s!). Are you dumping them because they are old? I hope you see why calling something "antique" is ill-conceived.

    Now to make sure that my point is being made clear, allow me to be explicit: old does not necessarily mean bad, but it does not necessarily mean good, either. Things that are old now were once shiny and new, and weren't necessarily an improvement when they were introduced. But change merely for the sake of change -- which seems to be what was behind debacles in KDE, Gnome, systemd, and Wayland to name a handful -- is wasted effort. For systemd in particular, the primary argument for using it seems to be parallel init, something that as many others have pointed out really isn't much of an issue these days since (a) Linux is generally stable enough that reboots are rare (although there are specific use-cases that benefit, like demand-based VM creation), and (b) computers have become generally fast enough that reboots are inherently speedy.

  2. Yes, sure, an interesting thought experiment, I suppose. Maybe. If you're the sort of psychopath who likes to pull legs off of small insects and animals just to watch them die. And, if that's the case, well, you need to be removed from direct contact with society and should be seeking treatment, possibly including protection from yourself. There is no legitimate use that comes to mind for a USB-killer other than to intentionally destroy property (unlike, say, a firearm which has legitimate uses beyond the raw ability to kill or maim). Moreover, it would seem to be targeted toward public-facing USB ports which are, in general, a public good, and destroying a public good brings us back to the psychopath issue.

    For everyone else, well, that sort of creative energy is useful put to more positive efforts.

  3. Re:Can you see Google's Code? on Google Search Results Have Liberal Bias, Study Finds (thedenverchannel.com) · · Score: 1

    Do not ascribe to malice that which can be explained by ineptitude. Or something like that.

    My understanding is that the result on Google, both displayed search results and auto-completion suggestions, are based on a large number of factors including (wait for it) your personal past history of typing, and the most popular results.

    Assuming that a "voting for ..." search would autocomplete with both main candidates equally assumes that there are as many people typing one candidate as the other. That is an unfounded assumption that is likely false. I searched a few times for a third-party candidate and lo! my autocomplete changed. The horror! Bias! Lynch them! Or, wait, maybe if I were searching for widgets that might be a good idea. Maybe if I were looking for somewhere to vacation, that might be a good idea. Maybe under circumstances that are not so emotionally incendiary, we might want exactly this behavior because it works very well.

    Any evaluation that demonstrates bias and is shocked by the results (or merely reports them) must prove unequivocally that the assumption of a lack of fundamental underlying bias in the data exists. A fundamental equality of data (e.g. the same number of web sites for the two candidates, the same number of twitter posts, etc.) is unlikely to be true in any of the cases being discussed in this thread.

    In other words, the original posting is not news. It is, to use the current vogue terminology, fake news. Lying with statistics. Click bait. Something to be ignored.

  5. Re:yes they should on Slashdot Asks: Should The US Abolish The Electoral College? · · Score: 1

    I'd also say guys like Nate Silver and Sam Wang may want to find something else to do, because this, even though I didn't believe, did end up being a Brexit-style vote, where traditional demographic models failed utterly and the pollsters and aggregators by and large got it wrong.

    Just because the models missed one election does not mean the models are useless, nor that they can't be improved. I'm sure that there is going to be a ton of analysis -- and rightly so -- to revise the models to the point that they would have accurately predicted the outcome. You don't abandon a solid, useful mechanism just because you encountered an exceptional case.

  6. The assumptions, from Noether's theorem stating that symmetries imply conservation laws, are that the universe is smooth, in the mathematical sense of smooth being that space is infinitely divisible. We know that last part isn't true: you cannot measure position to an arbitrary precision in the universe.

    Last I understood, the experiments that wanted to prove space to be quantized have not produced positive results as of yet.

  7. I've been saying for years (probably could find my posts saying as much on Slashdot, were I less lard-assed) that there are two things that are going to screw DeBeers utterly and completely.

    1. Diamond is a really quite nice semiconductor. Lots of good things about it.

    2. The semiconductor industry produces single crystal ingots that dwarf a typical natural stone by, what, three orders of magnitude, at five to seven nines of purity. They know how to make big, ultra-pure crystals in vast quantities much, much better than Mother Nature. And they do it at low prices, too.

    Once the semiconductor industry kens on to the idea of using diamond rather than silicon, it is game over for DeBeers.

    Heck, there's already a huge market in industrial diamonds. I've noticed some jewellery designers starting to use them, too. Just a question of time until the death knell for DeBeers, and they know it.

  9. Subtle distinctions, British vs. American English on UK's Brexit Cannot Pass Without Parliament Approval (aljazeera.com) · · Score: 1

    Every now and then there's a phrase that's put forth in British English that has us Americans gob-smacked. For example, back when the Grexit was all the talk, and there was discussion in the British press of the "potential failure of the Greek government" we Yanks were all up in arms because those words mean "failure of the society's mechanism for sovereign rule." Failure of the government, in American English, only happens during things like revolution or invasion.

    But to Brits, and those more familiar with the Parlimentary system, it means (to continue in American English) that the current executive-branch administration has lost power and a new administration will need to be elected through the normal mechanisms of the still-functioning political structure.

    A phrase in the summary above makes sharp the distinction: "Plans for Brexit are being challenged in a case with major constitutional implications, hinging on the balance of power between parliament and the government." Americans would think, "what? Huh? Isn't parliment part of the government?" A translation that would make us Yanks understand it better would be something like, "... the balance of power between the executive and legislative branches of government."

  10. Doublespeak explained on Phil Schiller Says the MacBook Pro Doesn't Need an SD Card Slot (theverge.com) · · Score: 1

    To paraphrase Phil's explanation: "we couldn't figure out whether SD or CF cards were better, so we decided to do neither."

    And that's despite the fact that essentially every currently available consumer, prosumer and professional camera supports SD cards or some high-capacity variant thereof. As a semi-pro photographer (meaning I get paid to shoot events, but that's not how I earn all of my income), I have not used a CF-only camera for something like 10 years now. Heck even Canon's flagship 1D has supported SD since MkII back in 2004.

    One is lead to the speculation that the real reason was to shave a few pennies from manufacturing costs by eliminating SD support.

    I use the Fn keys every day to switch between virtual desktops (and thus between applications, as I use each of my F1-F12 desktops for a separate application; can't figure out why everyone doesn't do that since it's gobs faster than using the mouse or Alt-Tab). I won't ever, ever be buying a computer that lacks the function keys. Ever. It would be highly counter-productive to do so for me. If I were forced to use such a keyboard, it would only serve to engender deep resentment to the manufacturer who created such an abomination, and the organization that required its use.

  13. Is the smart thermostat we see today the same one that was there yesterday?

    I bet this can be demonstrated to be equivalent to the halting problem. The question should be really: here are the spcifications of a certain device (whether dictated by the manufacturer, or determined empirically): does the present device match them? With every query from here to eternity? Under all circumstances? That smells like the halting problem.

    So, in other words, you can never be completely certain of the answer, only confident up to specific bounds. Maybe that's good enough, but $50K for that kind of work is not, and the amount of effort involved for the general case, is not. A good solution for the problem is going to be the sort of thing that would take a startup into a medium-to-large corporation.

    But there are really much better ways to avoid the problem in the first place. I mean, to paraphrase a processor of mine, we don't need a microprocessor in every doorknob. Just don't use the damned things. Your fridge does not need to be on the net. Nor do your chairs. Nor each door in your house. Your washing machine works perfectly well without being on the net. So does your garage door. The risks of putting highly insecure interfaces on such items just does not justify the potential benefit.

    No kidding. I have a pretty sophisticated self-specializing application that we rely on in my lab. It occasionally needs to create a semi-custom C program to run a particular computation with new parameter settings. It's so fast to generate the few thousand lines of C code and compile them that you barely notice the times when it needs to spin a new specialization of the code versus running an already-compiled version.

    The key is that it means a recent connection between the depths and the surface, and that would be huge for simplifying exploration.

    I know what I'm about to write is armchair science, and I do look forward to reading the full peer-reviewed article, but it's a pretty tall assumption that the plumes have the same composition as the subsurface ocean. We have now seen plumes all over the place, even from the surface of comets. It seems a little too much like assuming what we want to hear is true to state that the plumes are coming directly from the oceans. Furthermore, even if they are, whatever process creates the plumes is unlikely to maintain the chemical composition in unaltered form. While it will certainly be important to study the plumes for their own sake, without evidence of the mechanism driving them, it's going to be a hard sell to say that such study would allow us to examine the subsurface oceans in anything but an indirect way.

  17. Why do you think they won't be as loud as a helicopter? Fewer smaller rotors are louder than a single larger rotor pushing the same amount of air. The amount of weight is going to be approximately the same (or are these air taxis relying on a technological breakthrough that the helicopter industry hasn't yet found?), so the amount of lift required is going to be the same, thus the amount of displaced air per unit time will be the same. Many smaller rotors will need to spin faster and be louder than a single rotor that provides the same thrust.

    Think 80 mm PC fans versus 120 mm fans.

    Through a number of phases of the modern age, different airlines have attempted to offer air-taxi services from the three main airports around NYC to Manhattan. The economics would seem to make sense at first blush. The relative distances, potential market demand and locations make sense. And, yet none of the big airlines still offer these ad-ons to their mainline service, while, at the same time, they have offered significant incentives to attract big-money customers. The natural conclusion is that the devil is in the details and there must not be sufficient demand or market support for the routes to make financial sense. Not the least of which is that the fraction of the population who feels comfortable riding in a helicopter is small (consider how many people intensely dislike propeller planes, and then understand that helicopters are worse in nearly every way for ride experience when compared to jet flight).

  19. More silent? How can they be more silent? Silent means they make no noise.

    That said, VTOL aircraft are far, far from quiet. Even if you made them battery powered (good luck with that, as the power densities required are really pretty serious) to eliminate most of the power plant noise, they would still be damned loud due to the massive amount of air that needs to be thrust downward in order to move the craft upward. How much air? Equivalent to the weight of the craft. All the time. More, if you want to move up. Given that air is substantially less dense that most flying crafts, this means heaploads of noise. No matter how you cut it, aircraft are loud, close up, as long as you are depending on displacing air to provide thrust.

    A few small air bubbles, while not ideal, are not as bad as you might think. An important reason that you use the Hollywood-style flick-flick-flick to get air bubbles to the top of a syringe and then press them out is to make sure that you've filled the syringe with the appropriate amount of drug. Whereas 0.2 cc of air probably won't do much to you if injected (and that's a pretty big bubble in a syringe), if you're injecting 1 cc of drug, that 20% difference with versus without bubble can make a big difference in the mount of drug that actually gets delivered.
