A key question, though, is whether this kind of detection system can realistically block terrorists from bringing seemingly innocuous liquids past security and combining them later to deadly effect.
The simple answer is: No.
The more complex answer is: No, but it doesn't have to. There are no "seemingly innocuous" liquids (or, more general, "substances") that, when combined, form a feasible explosive. Explosives need an oxidizer (or be self-oxidizing, like nitroglycerin or TNT), and any substance with these properties is not innocuous, especially in the quantities needed for causing enough destruction to down the plane.
However, I wonder why no terrorist has brought two liters of hydrochloric acid on board. I would guess you can wreak quite some havoc with that, especially if you know where the vital control lines of the plane are.
*sigh* And I'll be flying to the States next month. What an experience to look forward to.
If one were to input this common bacteria into a operating nuclear reactor, would that mean that the reactor would clean itself the longer it operated?
No, it would simply mean that the bacteria die due to the high temperature. It's hot inside an opeating nuclear reactor.
If you put your stuff in your checked baggage, many times it will break open due to the pressure changes. Nice mess you have then.
Yeah but... shh... don't tell anyone, the same thing is going to happen if the stuff is in your carryon. The cargo hold is pressurized the same was as the cabin.
Fun stuff to try (well, before this whole mess): Close plastic bottle at cruising altitude. Watch bottle get crushed during descent. Wee.
Also, if you check your bag into the hold the 'plane simply WILL NOT take off without you.
However, this does not mean that the opposite is also true. The plane will take off with you on board, even if your checked bags are on the plane to Moscow.
And money is fine and dandy, but when you arrive in a unknown city in the evening and have an important event (business meeting, family reunion) on the next day which requires you to be up early and well rested, extensive shopping trips are out of the question.
Yeah, but do you need to use it on the plane? Why the hell do you need to bring it in your carry on?
Because the carry-on the the only thing you're guaranteed to have when you arrive at your destination. Your checked bags might arrive later, much later, destroyed, or never.
Only completely clueless people assume they will have access to their checked bags when they arrive at their destination.
When I travel I always list my "criticals" when I leave the house, and it doesn't take long:-
1.. Tickets
2.. Money
3.. Passport
Just wait until the airline sends your checked bags to Siberia by accidents and you're stuck at you destination without fresh underwear and clothes for a few days.
Basically, yes. What makes things interesting is that the exact amount of "too much" and "too little" (which is bad, too) varies drastically from individual to individual. And specific people can also have adverse, sudden reactions to the different anaesthetic agents.
(like anything else - alcohol for example).
Alcohol is usually self-administered and there are some natural safeguards against having too much which require a bit of training (drinking) to circumvent.
Let's just say that the most risky part of most surgical interventions is the general anaesthesia. That's why you need physician whose only purpose it is to monitor the status of the anaesthesia and the patient.
If you make your "second best" products by starting with your "best" products and then doing something to them which makes them less desirable so you can sell them for a lower price, you are effectively using labour to subtract value.
I think you didn't understand that yet.
The "best" product has been verified to work 100% correctly as the "best" product.
The "second best" product wasn't up to the specs of the "best" product, but isn't bad enough to be thrown away. Maybe not all of the pixel pipelines worked 100%, maybe its power consumption is too high at the frequencies of the "best" product, etc. Some of these specs might be irrelevant to the customer, that's why he might try and run the thing at the "best" specs.
And then there's the issue of having cheaper components on the card to produce a cheaper version. Even if the same GPU is used, it will run slower if paired with slower (cheaper) memory and/or a narrower (cheaper) memory bus. Or the GPU can only be clocked more slowly if paired with a slower (cheaper) cooling solution.
The implication is that if you hadn't done the downgrading work {which must cost some money}
The "downgrading" work actually consists of testing if the chip actually works, and under which conditions it will work reliably. So just skip that part and solder it in anyway ?
Does this (no formula) mean kids can't ride and there won't be any screaming brats on our flights? (God can only hope)
No. It will mean that all infants on board will be screaming non-stop. Ever heard a hungry (no, not cranky, _hungry_) baby cry ? You better bring earplugs. And hearing protection.
... oh, wait. They won't let you board with any of that. Looks like you're screwed.
I don't want to hear how the US targets innocents ever again.
No, they don't do that. No identified innocent is targeted by the US.
The trick is to skip the identification part. Targets are to be considered non-innocent until identification (and verification of identification, and triple-check of identification).
I remember last time they shot an innocent brasilian IN THE BACK, and it was discovered months later, and with chance, that he wasnt a terrorist.
No no no. They discovered minutes later that they had just shot a random guy.
What they discovered months later was that they weren't actually to blame for it. Well, a little, but there were too many people involved in the shooting to blame the death on a single person. Even whoever pumped seven bullets in the guys head was not at fault because all the information he had was that the guy was a dangerous terrorist.
Didn't Britain just introduce a terror threat level system a few weeks ago ? And right here is the chance to crank up the threat level a few notches ! The person in charge must be thrilled.
Another reason why they are unwilling to release the information might be because it would prove that they have been bullshitting us for a long time.
Dude, that's just, um, plain BS.
It is pretty well known what is on the cards and what the hardware can do. If you buy the 300 buck version, you're getting a piece of hardware that is guaranteed to deliver the bang of the 300 buck version. If you're buying the 150 buck version, you're getting guaranteed 150 buck performance - however, you may twiddle with the card in various ways (raising core/memory frequencies and activating additional pipelines) and maybe get lucky and have the thing run as a 300 buck version. The instances in which this works are pretty well known (most famous example: Radeon 9500 to Radeon 9700 pro mod) and have absofrickinlutely nothing to do with closed-source drivers. The nasty secret conspiracy you're painting on the wall here is neither secret nor a conspiracy, but just standard business practice.
Howevery, oddly enough, both NV and Ati ceased having OS drivers around the time their chips got put into Microsoft game consoles. Coincidence ?
Encode the really important stuff as DNA and add it to the genome of various critters (preferably some ubiquitous bacteria among them). Let reproductive behavior do the rest.
Of course, we need to make sure that the really important stuff does not contain an 'eradicate humanity' sequence by accident.
Or maybe they just believe that, you know, the US was unable to get a person to the moon in the 1960s and 1970s. Nothing to do with aliens, pyramids, evolution or creationism, just that they couldn't and didn't do it.
Why of course the US wasn't able to get a person to the moon. That's why they borrowed all those German rocket scientists, who were out their jobs anyway after launching rockets at London became unfashionable.
The Earth will be sterilised by the red-giant phase of the sun, in about 5 billion years.
Actually, Earth will be too hot to support life in just a measly one billion years due to the increase in the sun's luminosity as it ages. Until then, we should be able able to haul our collective asses of this rock or we're toast.
Of course, humans might just make this place uninhabitable for themselves in a much shorter timespan.
Using this stuff does not require finding the exact source of the bleeding,
However, I think you need to be able to _access_ it. Internal injuries are, well, internal and do not necessarily bleed outside the body. To use this stuff, you will have to cut a hole into the patient first, and of course know where and how to cut.

I think you've got cause and effect mixed up there. Let me fix that.
"There is something inherently wrong with the system when those who are more likely to be dishonest than the general population rise to the top."
What makes you think they have not done so yet ?
No, it would simply mean that the bacteria die due to the high temperature. It's hot inside an opeating nuclear reactor.
Yeah but

So, whatch gonna do when they find out about the first terrorist plot that involves terrorists stuffing explosives up their colon ?
"Just don't fly or bend over." ?

Actually, after 30 hours straight driving, the least of your worries should be whether the guy is going 75 or 100 mph.

Great. I would love to see the person who came up with this crap cough up some actual numbers.
So, critical means the chance of a major terrorist attack is how many percent per day ?
I bet they couldn't.
I think you didn't understand that yet.

"Clairvoyant"
At last ! Playing hundreds of RPGs over the course of two decades finally pays off !
That's because we evolved to benefit from them.
And pray why would none of the new species that arise be useful to man?
Because they evolved to benefit from the mess we leave behind, and they're probably not going to be similar to what we are used to benefit from.
