  2. Re:Hmmm .... on Physicists Gear Up To Catch a Gravitational Wave · · Score: 5, Informative

    LIGO works by measuring the distance between two tracks set at right angles. A passing gravitational wave would momentarily change the length of one leg or the other, or both, in characteristic ways.

    It measures the distance with a laser beam. It splits the beam, and sends them down the two tracks. They bounce off mirrors, and when they return, they interfere. Changes in the length will change the interference. That means that they can detect changes at distances on the order of a single wavelength of light.

    That's an interferometer, the I in LIGO. At its core, it's the same thing that Michaelson and Morley used to look for aether, and failed to find it. The trick is that this has to be even more sensitive, because the expected changes are even smaller and the contraption itself is much bigger (4 km, versus a few meters). They have to exclude all kinds of potential interference, from passing trucks to earthquakes.

    I suppose it may well go "ping" when it spots a gravitational wave, and they'll end up comparing it to other experiments. But they'll get more than a ping; they'll get a signal of the changing lengths that they can use to map the size of the wave, and even a hint of its direction.

    For some reason, he didn't head off to Newfoundland; he went at tropical latitudes. If he was trying to follow a line of latitude due west to Asia, he was going the VERY long way. If he hadn't bumped into something along the way, he'd have been deeply screwed.

    The direct route from Portugal to Japan would have taken him northeast. He probably had suspicions that the northeast passage wouldn't work, but the further north he went, the better. He'd have been better off going to Newfoundland. He would have failed to find the northwest passage, but he couldn't know that, either.

    The explanation that he thought it was smaller would account for that. If he was going based on his suspicion that there might be something that far south, he had little evidence to support it, and was really staking his life it. It certainly paid off in spades, but that could easily have been a lie he paid for with his life.

    As you say, "Andy Canfield" is kind of a red herring there. It's really the operational/instrumental definition of "is there some connection between this key and some object or information I want?" I'm not sure there really is any meaningful way to do that in the general case. It needs to be reconsidered as an array of different questions about why we care about identity in the first place.

    Right now a lot of the notions of identity are really badly defined. "Identity theft" happens because lending institutions are legally allowed to connect your physical body (which can be punished in a variety of ways) to various intangible measures of identity with extremely thin degrees of proof.

    Music is further made odd by the amount of money being spent to create demand. There's an enormous amount of marketing and advertising. Although there is some interest in the "long tail" of music, most of what people are willing to pay for comes from a well-oiled machine that has focus-grouped and promoted the bejeezus out of it.

    That costs a lot of money, and it's aimed at getting people to take part of their overall budget and put it into music that could otherwise be spent on many different alternative goods: different entertainment, food, materials, education, retirement, etc. They're also vying for a limited factor of people's time budget: while songs can be done in parallel to other things, there's only so much attention, and they can listen to only so many songs.

    A lot of factors enter into the economic model, and it goes far beyond just "supply and demand" even before you get the thumb on the scale of artificially-produced (and highly imperfect) scarcity.

    Code can, in theory, be made largely unhackable. The more features it has, the harder it will be, and there's always the five-dollar-wrench hack, but nothing in theory prevents people from securing the code.

    The law is always going to be hackable. Any significant law is always going to be far more complicated than code. It's dealing with people, not computers, who have far more different modes of operation.

    The law will always end up relying on a certain amount of goodwill from the people. We'd love to have the law say, "Look, just don't be an asshole," but defining "asshole" turns out to be tricky, and there will always be somebody willing to be just-asshole-enough to be legal.

    Worse... the law is retroactive: if you break it, the courts do something. Computer security prevents you from doing the illegal thing. That inherent delay creates inherent injustice. The delay also costs money. We've seen time and time again that it's been cheaper for companies to pay the extortion than to defend against it.

    So I think that yes, they are evil, and not merely hackers taking advantage of a broken system. Even the best possible system is imperfect. We rely on human beings to engage in a certain amount of decorum, if only for the game-theoretic reason that too much incivility results in a breakdown and they lose.

    Frequently, the patent trolls are breaking the law themselves, and counting on the delay to get away with it. That's pretty directly evil. And taking advantage of ambiguities in a system that must inherently be ambiguous, I'd say that's equally evil.

    Simply calling them "evil" doesn't really accomplish anything, of course. But it doesn't make them smart. The system is easily hacked. Anybody could do what they do. They're more akin to script kiddies than hackers.

    And that's precisely why YouTube is the go-to place even for a lot of copyrighted content: they're willing to play ball with the copyright holders (and arguably, roll over and play dead). That gives them access to a broad array of copyrighted content (like music videos) while ensuring that some revenue ends up in the hands of the copyright holder (if not the artist) by keeping out the copies.

    Other sources will always be patchy; YouTube will be the go-to source. Even for material they don't wish to host on YouTube, many people will go searching there for it first, and they can provide an advertisement (such as a trailer) that links them to their own preferred site to buy/rent the content.

    Others can try to break into that game by playing nice with the big studios, which heavily promote their own content and that drives a lot of eyeballs. But most people don't want to distinguish between that and the cat videos; it's all just entertainment.

    I'd be interested in reading the source to see what the argument is. Off the top of my head, the Irish Potato Famine strikes me as a pretty real famine. It was certainly exacerbated by political pressures, and they were growing monocultures in the first place because of the pressure for productivity. But it was a real crop failure, and they learned to reduce their dependence on a single crop.

    Certainly it could have been handled better, and far fewer people would have died. But I still think the death toll would have counted as a famine, or at best a famine barely averted by aid. I'd put it in a different category from starvation caused by war or corruption. Even the Great Chinese Famine could be chalked up to politics without too much of a stretch, but there are still crop failures due to drought and disease.

    Since the agricultural revolutions of the past few centuries and especially the last few decades, we're so awash in food that aid will always be stymied by people rather than lack of calories. But I'd put the tipping close closer to 40 years than 400.

    It's conceivable that there's a reason for it. The road as a whole should be a major arterial, but it's got an awful lot of stop lights. (This is just outside of Washington, DC, which has practically no proper arterials.) At rush hour, allowing people to go faster on this section than the overall speed of the road would be worse for traffic.

    What's really needed is to substantially restrict access to that road and make it a highway, though I'm sure that the businesses and residences along that road would hate it. The problem is systemic: there are no arteries and nobody wants to turn their stretch of road into one. There are zero interstates, so the roads are under a variety of local jurisdictions. I'm sure plenty of people complained to the county and state about that segment of road, but it's just a disaster for the whole region to deal with. And so it isn't.

    Er, anyway, that's kinda beside the point, which is really that what's needed is for the traffic engineers to design for steady flow and for people to follow it, even if they'd be more comfortable at some other speed, especially when lanes are limited.

    It's best if people all move at more or less the same speed. It keeps them better spaced. People driving much slower than that can cause as many difficulties as people driving much faster.

    We recognize the dangers of driving too fast, and most people try to keep it to near the speed limit, at least as long as the limit is set properly. Some are set very badly, and that's hazardous. You get a mix of people traveling at a safe but illegal speed with people obeying the law.

    Fortunately, I've found that most speed limits aren't too badly off. I'm sure there are jurisdictions where they're deliberately mis-setting them as revenue generators, but I don't encounter many of them. (I can name one not too far from my house, where a four-lane divided road with minimal access has a 30 MPH speed limit... and a speed camera on a big downhill leg. That's going to get people killed, because everybody who knows about the speed limit jams on their brakes and goes 25. And the road is a major arterial, or it could be, if they didn't deliberately limit the flow rate so badly. The road is, of course, a nightmare at rush hour and a speed-trap revenue source the rest of the time.)
