Comment Especially: The paint. (Score 1) 113

The gas bag itself was flammable; it wouldn't have mattered what gas was in it, when it disintegrated

In particular: The paint. It contained a mix of powdered aluminum and iron oxide pigments, in sufficient concentration to maintain a redox reaction.

You and I know this mixture as "thermite". It's really hard to get the reaction started - but an electric discharge can do it. (They tried to tether it with an electrical storm approaching. That would make one hell of a spark when the charged envelope comes near to connecting to the grounded mast - which is about when the fire started.) Once it's started, the reaction is essentially impossible to extinguish. The aluminum steals the oxygen from the iron oxide. The heats of formation of the two oxides differ so much that the energy released leaves the resulting elemental iron as an orange-glowing liquid and the aluminum oxide incandescent white-hot.

Comment That is a misreading of the Supremacy Clause: (Score 4, Informative) 213

You are bound by the treaties your country signed.

Yes: You, and the states, and their courts, are bound by them (to the extent they are clear or were implemented by federal enabling legislation).

In fact, they have more legal weight in the US than laws passed by your own Congress.

NO! They have EXACTLY the same weight as federal law. Both treaties and federal law are trumped by the Constitution, and both are also creatures of Congress, They can be modulated, and destroyed (at least in how they are effective within the country) by congressional action.

The idea that they're any stronger or more permanent than federal legislation comes from a (very common) misreading of the Supremacy Clause:

This Constitution, and the Laws of the United States which shall be made in pursuance thereof; and all treaties made, or which shall be made, under the authority of the United States, shall be the supreme law of the land; and the judges in every state shall be bound thereby, anything in the constitution or laws of any state to the contrary notwithstanding.

This says that the Constitution, Federal Law, and Treaties trump state law in state and federal courts. It says nothing about the relative power among the three.

The misreading is to interpret "all treaties made ... shall be the supreme law of the land ..." to mean that treaties effectively amend the constitution. This is wrong. You can see it by noticing the same kind of misreading also makes federal law equivalent to a constitutional amendment - which it clearly is not.

In fact the Supreme Court has spoken on the relation between the Constitution and treaties: In Reid v. Covert, 354 U.S. 1 (1957), the Supreme Court held stated that the U.S. Constitution supersedes international treaties ratified by the U.S. Senate.

Treaties are abrogated, at the federal level, all the time, and there are a number of mechanisms for doing so.

There are three professions where being untruthful is the key to success: Lawyers, salespeople, and marketing. All three are hired to portray their client in the most favorable light possible, and the very best ones lie through their teeth. The worst of these three are the marketers because they have legions of psychologists and scientists trying to figure out the best way to lie to people.

Yes! You're both presenting a perfectly defensible argument against marketing and reinforcing my original point! Because geeks tend to abhor marketing, we dismiss its significance, and are perennially gobsmacked as to why an intrinsically emotional, manipulatable species is so susceptible to emotional manipulation.

So long as humanity is what it is, reason will only ever get you so far. You either need to blow the doors off with a staggeringly amazing thing, or come to terms with the fact that every single entity who might care about your thing has feelings, and bending those feelings in your favor can work wonders.

It's not all bad, though; emotional manipulation works under much the same constraints. Unless you're a Level 80 Snake Oil Salesman with a hat full of luck, you're going to have a very hard time making your thing last if it doesn't live up to the hype--and your reputation will suffer for it.

The only real feature of note was Apple Pay, which might finally make NFC payments take off in the US. It's been a technology that should have hit it big a couple of years ago, but has never seen much consumer buy-in for some reason.

It's pretty straightforward, to my mind. With the exception of all but the most staggering technological advancements, widespread adoption of new technology typically requires:

  1. a sound implementation,
  2. a robust support infrastructure, and
  3. an effective marketing campaign.

Geeks, for a variety of reasons, tend to respect the first, grok the second, and abhor the third. I personally believe it's what drives our perpetual cycle of incredulity on this subject--because we so detest the last part of this equation, we refuse to see its importance in getting all those squishy, distracted, emotional bags of water to adopt cool new stuff.

NFC has never had the effective marketing campaign in the US, and only kinda had the support infrastructure. The iPhone has incredible inertia on the marketing front, and Apple have clearly done the legwork on building a good starting lineup of financial institutions and retailers for Apple Pay. It remains to be seen whether this'll be sufficient to make NFC catch on, but it's easily the closest we've come to covering all three of the bases above.

Now they have the guide printed on the box but I can remember when i was a kid they didn't.

Some off them had maps at least as far back as the '50s, and probably much further.

A classic was the "Whitman Sampler" - an assortment of their products with a handy map. In addition to being a tasty and relatively low-priced collection of their products, it let a family divide them up according to their individual preferences, and gave you the names of each, so you could (at least hypotheically) buy boxes of just the ones you like.

(I say hypothetically because I never saw boxes of the individual candies being carried in the stores that sold the samplers.)

Comment Re:RT.com? (Score 1) 540

It's an important difference.

Fox News is a right-wing punditry operation. They spin everything that happens in a light that promotes the viewpoints of US right-wing policy. If right-wingers are in power, they spin to the government's favor, and otherwise spin against the government.

RT is a literal government propaganda outlet. They have a story of what they want to tell people happened (regardless of whether it did or not), and tell people that it happened, to the point of routinely hiring actors as interview subjects. (side note: the Russia media really needs to get a larger acting pool, though... it's funny but sad when the same actor claims to be several different people for different stations in the same week).

If you see something inflamatory claimed on Fox, it's almost certainly spun. Possibly outright false, but unlikely - generally just highly spun. If you see something inflammatory claimed on RT, it's almost certainly false. Possibly just heavily spun, but generally willfully outright false.

Example: Fox News will pick random true stories from around the country, overplay them, and tell you that there's a War on Christmas. RT will hire a woman to play a refugee from Slavyansk to weepingly tell you that the Ukranian army is crucifying children in the town square to torture their mothers before killing them.

Well, I have to say, I've noticed something about Russia, and also about most (but not all) of the other former USSR states: the exact same sort of thing has kept happening under capitalism. Things like injecting a mother of a dead soldier with a tranquilizer on-camera when she spoke up during a press conference on the Kursk disaster, assassinating dissidents with polonium, arresting and outright assassinating journalists, sham trials to sieze assets either for the state or for Putin allies, heavy media censorship and the requirement for all major blogs to register as media outlets, elections so rigged that Chechnya went 99.59% for "The Butcher of Grozny", and on and on. It's no different today.

So, basically, the presence of these things says nothing about communism; it says that Russia has a history of strongmen leaders who confiscate peoples' belongings, outlaw dissent, condemn people without fair trials, and so forth. And when you look at these third world communist states, you usually find that their third world capitalist brethren rarely behave any better.

I think that communism, at least in its pure form, is terrible as economic policy. But one can easily run the risk of over-conflating.

But regardless of the pressure, when the helium leaks out, it will not be displaced by air. It will leave behind a vacuum. The helium will leak out, but nothing will leak in to replace it.

(Except maybe hydrogen, but there's not much of that in your local air.)

So your metal parts vacuum-weld and tear themselves apart starting at the contacting surfaces, and adding lots of hydrogen to the air around the drives just makes the parts become brittle on their way to failure.

Helium balloons are a minor part of the overall picture. The overwhelming majority of uses are industrial, such as cryogenics. The problem is that they don't recover it. If you want to make a big impact on the helium consumption rate, hard drives is pretty much one of the least effective places you could focus - focus on industrial recovery.

Note that humans will never "run out" of helium. Even if we assume that space-based resource extraction becomes realistic, one can always refrigerate it out of the atmosphere. Or more accurately, refrigerate everything else out and leave the helium behind. There's only a tiny bit in the atmosphere, but for important uses it'll remain a possibility. I saw page that says that neon is $2 per liter. If you're refrigerating neon out of the atmosphere, pretty much all that's left is helium, so you're co-producing it, at a ratio of 3.5 to 1. If we assume that helium demand vastly outpaces neon demand, then the helium cost would be $7 per liter. And maybe less in mass production.

That's not really an absurd price for many uses - such as hard drives. On the other hand, it's dramatically more than today's prices at about $0.005 per liter! You're not going to be making helium blimps at $7 per liter. But if industry learns how to recapture and reuse, they should manage.

(Of course, humans probably wouldn't have to resort to helium extraction from the atmosphere for centuries, pretty much any gas coming out of the ground will be richer in helium than the air)

Comment An overregulated province anyway... (Score 5, Informative) 184

Ontario is so overregulated that actions like this are practically ingrained in the culture of bureaucrats.

The government has a monopoly on all liquor sales. You aren't even allowed to buy certain cough medicines unless there is a licensed pharmacist on premises, even though while they're busy in the back you can just grab the stuff off the shelf. All stores MUST be closed on certain statutory holidays even if there are people willing to work those days, and the store is fined heavily if it opens anyway.

All of this is, of course, theatrics designed to garner the perception of an effective government while the Ontario government debt has risen by a third or $90B over the last five years alone. And they're worried about regulating foreign OTT services? I predict spectacular failure as it has been for the longest time in the province.

What original AC is saying is that our current medicine doesn't resemble Star Trek style ... We drop blanket bombs into our bodies with the expectation that the evil bits will die a whole lot faster than the good bits, and by the time the evil bits are dead, the good bits are still in a good enough shape to regenerate.

No that is NOT what we do for practically anything but chemotherapy for most cancers (where the difference from normal tissue is very small - a few mutations in signaling systems) and the main difference is that being stuck in reproduction mode makes them somewhat less robust.

Antibiotics are all about targeting one or another chemical mechanism that has one form in the target organism when its equivalen has another - or is absent - in human tissue. There are a LOT of drugs that have been discovered or designed, and the collection consists of enormous numbers of "magic bullets" that each target just one, or a small set, of systems found in particular pathogenic lifeforms, with either negligible, or far lower, side-effects on other systems.

Sure many antibiotics hit a wide range of NON-human life - pathogens and others - because THEY share susceptable versions of the target system or contain systems that are strongly side-effected. Sure the doctors sometimes have to pick drugs with bad side-effects because those are the best choices they have. But the characterization of antibiotic and antiviral drugs as "blanket bombing" has been out of date for more than half a century.

I'm not lying, that's the actual size, something like 420k. It may have been a bit shorter playtime, perhaps 20 seconds (I didn't time it), but still, it was quite small.

Nobody said videos on Facebook are Blu-Ray quality. But you seem to have weird concepts about how big videos need to be to be good enough quality for a web page. Just as a test, I took an original high quality full-motion video of a concert, reencoded it with ffmpeg, audio codec aac, vbr audio quality 0.5, video codec x264, preset veryslow, cf 33, resolution 512x288 (half original size), 20 seconds. File size? 420k. Of course the video from facebook was darker and quieter, so one would expect it to compress better. If we give my sample concert clip an allowable size of, say, 550k, then I can up audio quality to 0.7 and cf down to 30. Either way, the resultant clip was fine, the sort of thing you'd expect to see on a Facebook wall.

Anyway, the key point is, Facebook feeds aren't loading you down with 50 meg videos, they're little couple-hundred-k clips, the same size as animated gifs. And while I haven't measured it, they don't appear to start streaming until you scroll down to them, and look to stop after you scroll away.

Comment Re:Taste like chicken? (Score 1) 107

Recent research has shown that chickens are the closest living relative of T. Rex.

Do you have a reference for the research?

If it's true that T.rex is closer to chickens than to pheasants, peafowl, and other Phasianinae, it would mean that the Phasianinae family dates back to before the K-T disaster.

This was all over the mainstream press last April. I was echoing their over-simplified characterizatoin of the research.

It's actually "closest living relative among the set of genetic databases they tested", I.e. chickens, sheep, etc. Chickens happened to be a bird they tested, with aminno acid sequences far closer to those of the collagen recovered from T. Rex - nearly identical, in fact, than those of things like mammals. So don't expect this to re-write taxonomy - or to mean that chickens were any closer - or farter - from T. Rex than their close relatives such as phesants.

Of course there's other evidence that birds were around well before T. Rex. So it may turn out that chickens are closer relatives to T. Rex than, say, bluebirds. (Or maybe bluebirds will turn out to be closer, once they're compared.)
