  1. Why the switch in nomenclature? on Ghost Towns Is the First 8K Video Posted To YouTube -- But Can You Watch It? · · Score: 1

    I know I'm way behind the times when it comes to consumer electronics, but the last time I bought a TV I wanted a 1040p, and kind of assumed that 4k and 8k would have 4x and 8x the vertical density of that. Apparently not; Wikipedia sayeth that it switched from vertical to horizontal resolution.

    Now that I know this, it's not difficult to understand. But I'm curious as to why they'd change naming conventions. Is there any particular reason?

    When was the last time the USA had 3% growth?

    Last year, at 3.7%. And the year before, and the year before, and the year before. The last time it was under 3% was 2010, when it was 2.1%. For the first quarter of 2015, it was an annualized growth of 3.6% (second estimate; the Q2 estimates aren't due until the end of next month).

    The US did, indeed, decline during the recession: growth was flat or negative in 2008 and 2009. But GDP increase year on year has been pretty consistently in the 3.5-4.5% range since the close of the recession. Source.

    Not that GDP is a great measure of economic success, but you were the one who brought it up. Practically all of that GDP increase goes to a tiny percentage of the population, and they fight hard to keep it that way. The rest is treading water or falling back. But as a whole, by the coarse measure of GDP, the US has been doing quite well ever since the end of the recession.

    Cops are more than four times more likely than ordinary citizens to shoot someone who doesn't deserve it in any given armed altercation and kill citizens at 70 times the rate of other first-world nations

    I believe there's a chicken-and-egg thing there. The cops are armed because the criminals are armed. Every time a civilian is shot, we're told that it's because the officers had reason to fear for their life. Even when the civilian is unarmed, the officer gets to use a weapon that can kill at a distance, and they have that weapon at their disposal.

    And they actually ARE at risk: last year, 49 police officers died by firearm (two accidentally). (Another ten by vehicular assault, and two by the kinds of non-gun, non-car kinds of assaults that seem to make the headlines when civilians are killed.) In return, about a thousand people are killed by police. Many of whom, I suspect, were in fact dangerous... because they also have guns. Or at least, might.

    I don't know how other countries avoided this chicken-and-egg problem. Mostly, I suspect, by limiting firearms before mass production made quality, portable, concealable firearms readily available. (I'd be perfectly content with an "originalist" reading of the Second Amendment. Go ahead and issue everybody a black-powder rifle, which is what "arms" meant in 1791.)

    Regardless, I don't really know how to un-screw this pooch. And a thousand civilians will die this year, along with a few dozen police officers, because of it.

    Ironically, once we get past that point, we can actually do away with all of the stop signs. They exist only for humans, who have limited reaction times and can only see line-of-sight. The computers will be able to know where all of the other cars are (at least, the one with transponders). They'll signal, but they'll do it in a far more meaningful way than just a blinky-blinky light.

    They can probably even go considerably faster than the current speed limits, safely. But they probably won't have to, since the those 5-10 mph are rarely big enough to make a significant difference in your arrival time. The only times when it would really matter is when you're making very long trips, and then we'd want to take into account the significant additional fuel costs of driving that much (compared to just leaving a little sooner).

  7. Re:It's not stealing. on Bell Media President Says Canadians Are 'Stealing' US Netflix Content · · Score: 1

    Is it the customer who's causing the copyright violation? Or is it Netflix, for feeding the content to somebody not coming from the US?

    I would assume that Netflix would be considered sufficiently diligent in having attempted to feed it only to US-based IP addresses, but perhaps they have a case against the VPN provider? Or against the customer themselves, not for the copyright per se but for violating the terms of use (which presumably say "You will only use this from America, and not attempt to fool us with a VPN")?

    Perhaps that would be the ultimate way to put it, that the customer is attempting to defraud Netflix, putting Netflix at risk of violating their licensing terms. I'm not sure what the law has to say about such cases, where you've got a chain of causation. It would certainly be wildly inefficient for the providers (all of them) to sue Netflix for violating the terms, then have Netflix attempt to recover the money by suing those who broke their own terms. But that would be, as far as I can tell, the logical chain of events.

It puts him competing with Martin O'Malley for a shot at the VP chair, unless on the off chance something totally tanks Clinton between now and February. Which isn't impossible. (There's also Sanders, but he doesn't want the VP chair and I don't think he really wants to take over if she does tank. He's just trying to force everybody else to run to the left in a party that has run very hard to the center.)

Slashdot, being Slashdot, tried to make news-for-nerds out of it, but all it generated was a lot of the same old talk about the merits and difficulties of switching to metric, all of which is decidedly Not News.

    For some reason, al Qaeda seemed to have a thing for planes. They did try after 9/11, like the Underwear Guy and the Shoe Guy, though both were quite incompetent.

    I suspect it's related to people's general fear of planes, even though they know on a per-mile basis the planes are really safe. The combination of the rather remarkable fact that they fly at all, that people are trapped in them, and the spectacle of many people dying at once seems to attract a lot more attention than it really merits in terms of the sheer calculus of death. Terrorism became really prominent through hijacking and bombing planes. It still seems to hold a fascination.

    It is notable that we haven't seen any attempted bombing or hijacking for quite some time. Perhaps al Qaeda has realized that it's pointless, though they're not really doing all that much against softer targets, either. I think we all know how easy it would be, and how much disproportionate terror it would cause in Americans, and I don't really know why they haven't tried harder.

    The Everest-hole hole is extremely hot, 10^8 K, but it's still radiating so slowly that it'll take 10^21 years to evaporate, so it would be more than enough to destroy the earth.

    I'm not quite sure how to solve for one that would be hot enough to suck in the earth before evaporating, but I see that a black hole that would last 1 second is a mere 70 million kilograms, with a radius of about a picometer.

    It's denser than that. The Schwartzschild radius of a black hole with a mass around 10^15 kg (a rough guess) is about 10^-12 meters (about a picometer). Give or take a few orders of magnitude. Wolfram Alpha has a convenient Schwartzschild radius calculator. The evaporation time for a black hole that big is 10^30 seconds.

    The smaller a black hole is, the denser. The number you give is for a star-sized black hole. There isn't any known way to form grain-of-sand sized black holes, though they might have formed in the very early universe.

    Record albums are kind of the pop equivalent of a symphony. They last roughly the same time, the length of a CD. It's a myth that it was chosen to be the length of Beethoven's 9th, but the intuition seems to be about right: that's about how long people are willing to listen to music before they need a break.

    Not all albums are constructed well, but a good album has some kind of structure and forms a complete unit of music, rather than just being a bunch of songs. It's about as unified as the movements of a symphony. Songs don't quite correspond to movements (a movement is likely to be 15 minutes, a song 3), though as you say there is yet more structure within a movement.

    These attention spans are probably not absolutely fundamental to human nature, but they're at least deeply culturally embedded.

    It is too bad that things seem to have settled in a place that have eliminated long-form songs like Bohemian Rhapsody and Stairway to Heaven (about the length of a symphonic movement, and each definitely composed of sections that are very different musically). I would be very happy to see those return, though songs like those are rare epics, requiring tremendous skill and insight to construct. I don't know if Pandora will want to play them to you, since it means they get paid just once for feeding out bits that they could have been paid 3 or 4 times for, but I suspect that if somebody writes a great song like Stairway there will be demand for it. The streaming services will want to serve that demand, and since they have control over how often it comes up, it may cut only a tiny bit into their profits.

    The crux, as I see it, is that an add-on box is clunky compared to a TV. It's a thing that has to be installed. That's not vastly hard, but it's a power cord and a data cable, and it just kinda hangs off of your TV. That's not elegant. (Note: I don't have an Apple TV, but I don't get the impression that they have any better solution than my Roku does.)

    They can certainly make the software better, but I can see why they would want to sell you an entire television to make the entire user experience just right. It's kinda too bad that it just doesn't add enough value to a TV to make it worth the trouble. Apple has always succeeded best when they could make their solutions elegant, in ways that seem obvious yet nobody had done them until Apple did.

But my phone does a better job, especially since it has wi-fi built in, and I am going to be carrying it around anyway.)

    So I think (and I believe you agree with me) that this is really caused by the investor class failing to invest.

The Fed is offering free money, and instead they're putting their cash into the bank.

The Fed hasn't been willing to go that far (they'd rather that the legislature do it if the investors won't), but they have repeatedly refused to raise interest rates. That's the action they take when they're afraid of inflation; it's the punch bowl they take away when the party gets going.

    Effectively, they have been. The Federal Reserve has been keeping interest rates at levels that should be causing significant inflation. The goal is to prevent a deflationary spiral by pumping up the money supply: when you can borrow lower than inflation, people should borrow and pay it back with tomorrow's less-valuable dollars.

    They've been doing that for nearly a decade now, and it has successfully prevented the deflation, but it's a little baffling that it hasn't touched off more inflation than it has. The consumer confidence is hovering around 100, which should be a decent level for a stable economy. Unemployment is still higher than we'd like but it's well off the bust years.

    My hypothesis is that people have gotten too used to boom economies. If people aren't getting triple-digit returns they don't want to invest. What we've got is a very stable economy, exactly the kind that people should be able to take risks in, but without a real estate boom or dotcom boom or other scheme to get people to dump their whole life savings and then borrow on margin, they just don't bother.

    Stability means that those who have been left behind continue to be left behind. That's the worst thing that can be said about the economy. There just isn't an engine of growth.

    There are a lot of other factors, I'm sure. Europe went mostly for less aggressive measures, and their economies haven't come out as well, meaning fewer markets there. China's growth has ceased to be ridiculous. Oil prices should have sparked some kind of boom, and I've got a nasty cynical feeling that Wall Street is ideologically predisposed not to invest in the emerging energies as much as they should.

    But a lot of it is the catch-22 you mentioned. Consumers and investors each seem to be waiting for the other to go first. We've been technically out of recession for more than five years, and it's gotten past the point where the recovery could be called mere accounting. It's real. But America just hasn't gotten its feet back under it in the way that it usually does.
