In any case, I do agree that it's not worth the money. Not because it's snake oil but because non-quantum computing will probably never break RSA. And if it turns out that entangling qubits to each other is exponentially difficult, then RSA should be able to keep well ahead of those as well.
That's really how it works. For each bit you just randomly pick a basis and measure it. Later the sender announces the true basis and if you measured the wrong one then you just throw that bit away.
Remember, this is cryptographic key exchange, not encryption. We already have a perfectly unbreakable cipher, one-time-pad. QC solves the problem of coming up with the pad itself.
E: That sounds cool! But wait, how do *we* know whether to read the polarity or frequency of a given bit?
S: Oh, no problem, you send that information ahead of time on another channel!
Ah, that's where you're confused. You reveal the basis vectors AFTER, not before. And you reveal them publicly, perhaps via radio broadcast, NOT over a secure line.
You can't store and forward because you don't know which basis to store!
That is disgusting, though unsurprising. And it probably accounts for why there aren't any coupons if cable subscribers are being deliberately misled en masse.
I find it surprising and disappointing that a community of scientists, engineers and other educated people such as Slashdot have such an odd view on science. Now, I'm not entirely convinced of GW myself. But the general line of reasoning seems to go "since Nostradamus was wrong, then clearly Susan Solomon is wrong as well". That is about as valid as saying that Einstein has to be wrong, because alchemists and clerics have been wrong countless times about the nature of the cosmos.
Surely the point of this research is add another data point to the sum of our knowledge, and to encourage innovative solutions that she hasn't considered. NOT to drive the public to hysteria. From TFA: "I guess if it's irreversible, to me it seems all the more reason you might want to do something about it." (emphasis mine)
If you find 1000 Americans and total up their health care expenditures, it will total $2 million. 25% spend nothing, 25% spend a ton, and 50% have $2000 insurance so the median cost is $2000.
If you find 1000 Canadians and total up their health care expenditures, it will total $1 million. The 10 richest people out of the 1000 cover $1.8 million of that, so the median cost is $202.
Actually most developed nations with universal health care pay about HALF what we do per capita. Germany tops out the list at about 75%. I can't say that nationalizing would make it cheaper, but I can't imagine it possibly getting any worse.
You're correct, the correct phrase is 'under Democrat control'. 'under Democratic control' is just as wrong as 'under Republic control'
In any case, in the American system there are for all practical purposes only two parties. There are things they both agree on (increasing spending) and things that are strictly divided along party lines (reproductive rights), and practically nothing that's a gray area.
If that sounds absurd to you, then now you know why we all just vote for the tallest candidate and go back to drinking beer.
There are four fundamental circuit variables: current, voltage, charge and flux.
Resistance relates voltage and current.
Capacitance relates charge and voltage.
Inductance relates flux and current.
Memristance relates flux and charge.
Thus M is the 'missing relation'. I'm not so sure I buy it either, but that's where they're coming from. Perhaps LTI was just an incredibly useful coincidence.
Even with a complete set of blueprints it would be much easier to start from scratch than to try and build a Saturn V. For a small example, log on to newark.com and try to order some magnetic core memory. Similar situation for all the mechanical components, not to mention the required expertise that's been lost.
At TMI about half the core melted and formed a puddle at the bottom of the pressure vessel. Even though they eventually pulled their heads out of their asses and saved the day, that is most definitely an "issue".
Disclaimer: That's not to say that we haven't learned anything in the 40 years since TMI was designed. I find it absurd that we stopped making nuke plants. We should be building shiny new safe ones so that we can decommission all the old time bombs.
I'm glad all the whining us Linux fans are doing is paying off. Everybody's jumping on the Linux-supporting bandwagon, if only to stop us from telling all our friends and relatives and strangers that $COMPANY are a bunch of evil meanie heads.

I suggest you RTFWA rather than argue further.
If I may take a moment to be a smartass: Assuming your P4 has a 25 watt power supply, the internet is about infinity times faster.

Milhouse 893,000 results.
Does this mean Milhouse is a meme???
What isn't quantum about exchanging quanta of light, and what isn't cryptography about computing a shared secret?
That is disgusting, though unsurprising. And it probably accounts for why there aren't any coupons if cable subscribers are being deliberately misled en masse.
This transition only affects over-the-air broadcasts! If Cox is pulling your analog then it's a pure coincidence.

While we're on the topic of burning karma to point out moderation flaws, your post definitely deserves a -1 No Sense of Humor. Get over yourself.
The reception is worse because the ATSC stations can't transmit at full power until the NTSC stations go dark. ATSC interferes with NTSC reception.
RoHS is an EU standard restricting, among other things, lead solder. Most devices sold in the US comply simply to avoid separate assembly lines.
Anyway to address GP's point, lead-free solder has gotten WAY better even in the last few years.
All figures pulled out of wazoo:

I know that we pay way more for administrative overhead and for drugs. Probably a lot of malpractice dues in there too.

As stormydragon pointed out, I included the passives but forgot the two supplies:
A current source relates charge and current.
A voltage source relates flux and voltage.
There are four fundamental circuit variables: current, voltage, charge and flux.
Resistance relates voltage and current.
Capacitance relates charge and voltage.
Inductance relates flux and current.
Memristance relates flux and charge.
