An oversimplification. The US, UK, and allies variously broke many cipher systems throughout WWII. Still the US benefitted from this.

What if the Germans were using, say, Windows, Android phones, SSL, Gmail, Yahoo, and Skype, instead of Enigma machines?

I presume you wouldn't say it was "wrong" of the United States to crack the German and Japanese codes in WWII... when US adversaries (and lets just caveat this by saying people YOU, personally, agree are legitimate US adversaries) don't use their own "codes", but instead share the same systems, networks, services, devices, cloud providers, operating systems, encryption schemes, and so on, that Americans and much of the rest of the world uses, would you suggest that they should be off limits?

This isn't so much a law enforcement question as a question of how to do SIGINT in the modern digital world, but given the above, and given that intelligence requires secrecy in order to be effective, how would you suggest the United States go after legitimate targets? Or should we not be able to, because that power "might" be able to be abused -- as can any/all government powers, by definition?

This simplistic view that the only purpose of the government in a free and democratic society must be to somehow subjugate, spy on, and violate the rights of its citizens is insane, while actual totalitarian and non-free states, to say nothing of myriad terrorist and other groups, press their advantage. And why wouldn't they? The US and its ever-imperfect system of law is not the great villain in the world.

Take a step back and get some perspective. And this is not a rhetorical question: if someone can tell me their solution for how we should be able to target technologies that are fundamentally shared with innocent Americans and foreigners everywhere while still keeping such sources, methods, capabilities, and techniques secret, I'm all ears. And if you believe the second a technology is shared it should become magically off-limits because power might be abused, you are insane -- or, more to the point, you believe you have some moral high ground which, ironically, would actually result in severe disadvantages for the system of free society you would claim to support.

Comment: Farmers != Farm Workers (Score 0, Troll) 122

The headline says farmers. The text says farm workers. Very much not the same thing. A farmer is the owner of the farm. A farm worker is generally a hired hand, often (though not always) a migrant, and if so typically from Mexico or farther south.

The story suggests that the multi-drug-resistant bacteria are the result of antibiotic treatment of the animals at the farm. This misses another possibility:

In Mexico, most antibiotics are over-the-counter, much like asprin here in the US. People who feel ill or have some infection often buy and take them. Typically they use them until they no longer show symptoms - then stop, rather than taking a full regimin and killing off all the bacteria. (Why take more of the non-free drug once the symptoms are gone? Waste of money, right?) This is a recipe for creating drug-resistant bacteria.

Of course if an infection is resistant to one antibiotic, a paitent is likely to try another, and another, and so on until they find one that works. THAT's a recipe for maintaining and improving the bug's resistance to the front line antibiotics while breeding resistance to others.

As a result, a substantial fraction of the workers arriving from south of the Mexican border are carriers of multi-drug-resistant baceria.

Meanwhile, a farming operation is likely to give a limited number of antibiotics continuously, so non-resistant infections are wiped out before they can develop resistance, and if they do develop resistance it will be to the particular drugs used, rather than the universe of antibiotics.

Of course, infected workers can infect livestock, just as livestock can infect workers. And infected workers can trade infections around, just as livestock can. (More so, since the livestock tends to be kept separated, to reduce both disease spread and breeding by unintended pairings, limitations that farmers can't impose on their workers - and would be unlikely to try even if they could.)

So it seems to me that responsible researchers would go a bit farther before reporting: Like by doing genetic testing on the strains of bug in the various workers and the livestock, and running models on the results to try to identfy whether the bugs are from the herd or the workers.

I don't see any such work alluded to in this popularized reporting. It seems to just assume that the bugs were developed on the farm and spread to the workers. I hope this is a disconnect between the actual research and the report, rather than an accurate characterization of the research.

Because of the architecture, you have to implement a timer using the processor's built in precision timer/counter. There's one there... You can get sub-microsecond control resolution if you implement it right. The risk is that if you're running a multitasking operating system your timer might get interrupted. Of course, another way to go is to have a secondary I/O processor handle the task and act as the interface -- this is very common when dealing with Intel processor platforms.

Yes, maybe they're all genetically modified self absorbed drug addicts... Eventually they'd get bored and come on over to see if we had better drugs here than they had; something they hadn't tried before. Or maybe they'd just get the munchies and come here looking for better snack food. Or get tired of us bringing down their high with all our fighting; and come by to tell us to "mellow out, man."

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.

Of course I know where it comes from... It's extracted from natural gas as a byproduct and initially helium comes from alpha decay of radioactives, as you say. Producing it through radioactive decay, that's the slow way. Helium is produces in a number of fusion reactions. They don't have to be energetically favorable to produce helium. Now... if you want cost effective, then that's another problem.

You know, the difference between this company and the Titanic is that the Titanic had paying customers.
