I've heard at least one person here report that at least some of the 'safety problems' amount to missing signage, and stuff like that.
... And if one of the missing signs is supposed to read "Turn this valve for emergency shutdown", or worse yet, "Never open this valve" (shades of Joe Versus The Volcano:-) Are the concerns still minor?
I know that particular contrived example is unlikely and rather silly; it's just the other side of your pointing out that we need the whole story. Absolutely agree.
It's more vapor, guys. Send me an email when it has a price. Wake me when the price is 7X a hard disk for the same size. Instant message when it's cheaper than a same size hard disk. Yeah, right. I'll expect that in about 2525.
By keeping the source closed, he is in fact assuming all responsibility for the actions of his code.
I'm not buying that. You can send a ransom note using Microsoft Outlook Express. Do you really think therefore that Microsoft bears responsibility for a user breaking the law by so doing? Both Outlook Express and Bittorrent enable useful activity that is not breaking the law, as well as illegal activity.
As someone who's lost two hard drives in the last year, I don't give a damn about energy efficiency. I want reliability. Thank $DEITY that solid-state drives are finally coming. Just a few more years...
Flash memory (un)reliability and (terrible) lifespan will make you pine for the good old days of super reliable mechanical hard disks.
You're right that frequency and power are different. Mutations require ionizing radiation; basically alpha/beta/gamma rays, neutrons, cosmic rays, etc. Well into the ultraviolet is about the lowest frequency that can be mutationally dangerous - somewhere around 10E-8 m, or thousands of times higher frequency than millimeter wave RF.
All millimeter wave RF can do is heat objects. It can do this promptly and well below the surface. With enough power, it can kill you pretty quickly by simple heating, but that's all. With a well focused beam, your brain could be literally cooked basically before you notice it. But practically speaking there is no intensity or duration of microwaves that causes mutations.
If such a thing exist, which i doubt it does, then why would they use it on protesters? If they have developed this type of technology, then I'm sure they'd deploy them in high priority areas like in the Middle East, China, etc..
Says anyone who understands why we have juries of our peers rather than juries of government-appointed experts, when the latter could incontrovertibly do a much better job of deciding the facts of the case.
Jury nullification, not the USSC or the presidential pardon, represents the final and most effective of the "checks and balances" on government abuse of power.
+1,000,000, DEAD ON!
Absolutely, juries answer to no one and it's one of the most vital pillars of the Republic! The jury in this case was lacking, but the power is there.
Polyvinyl alcohol is derived from vinyl acetate, which in turn is made with ethylene and acetic acid with oxygen and a palladium catalyst. Petroleum is not necessary in any of these steps.
Just out of curiosity, where are you getting your ethylene? Ethylene is produced in the petrochemical industry by steam "cracking". In this process, gaseous or light liquid hydrocarbons are briefly heated to 750-950 C (thanks, Wikipedia). So if it's not from petroleum per se, it's no doubt (in practice) consuming hydrocarbon deposits. Yeah, you could synthesize it. You can synthesize pretty much anything - in the lab. You can synthesize gasoline. But ya gotta figure there's a reason nobody does in practice (with pretty inconsequential exceptions).
Oh, production is energy intensive, too. A typical world scale ethylene plant (about 1.5 billion pounds of ethylene per year) uses a 45,000 horsepower cracked gas compressor, a 30,000 horsepower propylene compressor, and a 15,000 horsepower ethylene compressor.
Flexibility is defined by Young's Modulus, "E". Carbon fiber has a much higher ratio of Young's Modulus to weight, and a higher outright value of Young's Modulus, than aluminum.
How is this statement different from the statement it was a response to, save that it's longer and contains more obscure terms?
Sorry, I unthinkingly left out the rest of it. High Young's modulus equals high stiffness and less flexibility.
I'm inclined to agree, and more importantly, carbon fiber is happening. It's going into all new designs. We're going to see it in cars, too. It's just a matter of time.
Carbon fiber is also a lot more flexible than aluminum and it's lighter.

Like inhaling toxic smoke is going to be your big worry if the PLANE is ON FIRE.
Actually, yes, it is. Carbon monoxide and cyanide gas in smoke is the biggest killer in fires, including aircraft fires.
"Oh crap! The plane is on fire! Make sure not to breathe in case you get poisoned!" Is that really the biggest concern at that point? Seriously?
Actually, poisonous fumes are a prime killer in any fire, including aircraft fires. Cyanide gas, released from burning seat material, has been the agent of death in many cases.
Another standout example is the M2.50 caliber machine gun. The good old Ma Deuce 50 cal. Introduced in 1921, still in service everywhere, and better than anything else in its class. A thousand times better than the piece of crap XM312 slated to replace it.
I wouldn't like to be subdued by any of them, thank you very much...if you're going to give the police a weapon, there's an argument that a gun is better than any of these. Everyone knows that a gun is lethal, so a policeman is going to think carefully before using it on anyone who is not immediately threatening his life. But if the policeman has got a simple non-lethal weapon like this, he's got a strong motivation for "subduing" anyone who happens to disagree with him or who doesn't instantly obey his orders.
Your argument has merit, but on the other hand I am afraid that the policeman will always have ostensible "non-lethal" weapons that cannot be taken away: his fists, his shod foot, and his billy club. Hapless citizens have been killed by all three even though the policeman (ostensibly at least) has no intention of killing them.
Give the policeman this bright light thingie, and (1) if you are optimistic, he has a better first choice if he really doesn't want to cause bodily harm or kill you, and (2) even if you are pessimistic, he is less likely to use more dangerous implements, because it would be harder to explain away in court.
OS X has a hybrid kernel, XNU, a major part of it based on Mach, as well as incorporating sizable bits of FreeBSD, plus Apple bits that are not related to either one. It's not Mach, and it's not FreeBSD.
Follow the links above if you really want to see how the above poster is misrepresenting things
No, dbill, it is you who is misrepresenting, and/or evidently not following the links attentively, or with comprehension. As the other respondents have pointed out, the bug has nothing to do with optical drives. It has to do with large hard-disk copies making the entire system unresponsive. It is a very serious bug. You're of course right that it's not all broken, but there is a serious/crippling flaw here showing up in certain classes of system configurations.

And not as good as the MG-42 either.
Dude, the word is isotopic, not isotropic.
Subdue: verb: 1 : to conquer and bring into subjection.

I said rational mind, moron ... not military mind. Asshole.

Not in a rational mind, it doesn't. Sorry.
