I'll take you up on that bet, how much money do you want to put on it?
I had thought something similar about the Apple displays until a guy at my work got one. I went to go look at it just to prove to my self that my 22" Mitsubishi 2060u was a way better monitor... I was blown away. I have never seen anywhere near such a beautiful picture. It was amazing. I just kept saying, "wow."
At any rate, $1050 is not between $750 and $1000 for future reference, so don't let the sales guys get you on that one next time.
Okay, keep your pants on man. Go to google and type "Airport 3.4" and see what the news stories are. Notice they all are titled things like "fixing [...] 3.4" or "improving [...] after installing 3.4" or "[...] uninstal[...]"
Actually the reason you change keys is two fold. The less important reason is the one you state (it is almost imposible to guess a key). the more important reason is that the key give away information about itself with every bit you transfer past its length. I.e. perfect security is to transmit every 128 bits with their own 128 bit key. This is often not pratical, so the next best thing to do is to change keys often.
To minimize probblems you could transmit (via trusted courier) once a month enough keys for several million per day (this would fit on a CD) and then just switch every hundred microseconds. The only advantage of the quantum criptography machine is that you don't have to trust a courier OR public/private key encription.
Right, but it looks like the detector has to be 100% efficient, otherwise, how do you know if you got a zero (no photon) or if the photons just got absorbed somewhere? As far as I know, there no 100% efficient counter (cooled PMTs can be close, but not that close).
No, a social attack can work on a much higher level than this would work (think the master password to the accounts). Social attack is far and away the most serious security holes that anyone has.
Secondly, even if they were related, you're appear to be suggesting we might as well not bother patching one future security hole because a different one also exists? Thats crazy. We should tackle all security risks, not just one particular one.
No, the question is one of resource allocation. At present, there is no known (implementable for less than billions within 50 years) method of factoring these large prime numbers that are used to store the keys, so why spend money on this when you could actualy prevent a security hole. Your right, if money was ininite, all security holes should be worked on. As is, we should work on holes that have a possibility of causing a leak in the next 50 years.
Lastly, socially engineered attacks are most often people giving up a PIN or forging a signature.
It's not what is most common, it is what costs the bank the most after it happened. That is social engeneering.
It look to me like you could use a beam splitter to defeat this--unless it is a single photon, in which case I don't understand how you don't loose lots of data.
Also, both the transmission point and the end point need to know what the polarization is going to be before hand...if you know that, why not just use that sequence as your encription key?
Well, you have to admit, that is a security improvement... now people must be closer to your base station to try access it.

Contrary to what the article says, I actualy have to say that I took a class from some of the world's best respected oceanographers and they didn't see this as out of the qeustion in the near term. they thought the melt rates were so great that the water could stop sinking in the near term.

You can also use clear tape to tape a piece of white paper over the LED (or several), this is drastically decrease the intensity, but still let you see the LED if you look directly at it.
There is the whole energy efficiency things too. New York for example is switching its stop lights to save energy.

Actually, pure greens are fairly new...this is the only reference I can find, but I recenly interacted with some people who work in a field where we were dieing for pure green LEDs for a long time, and they just recently got them.
" Seeing as our Constitution enumerates the powers given to the Federal government, while specifically stating that all other powers are inherently reserved for either the states or the people."
I'll bet if we went over every inch of the Federal government with a fine-tooth Constitutional comb, we'd be able to cut the Federal budget in half simply by eliminating aspects which are illegal to begin with.
okay... Show me how to trim half from these programs (2003 budget numbers):
Interest on the debt ($181,000,000,000)
Social Security ($472,000,000,000)
These add up to about 1/3 of the budget and neither has hardly any management costs (less than a few percent). If you want to see the raw data, look at the white house's budget page. They are in the summary tables section.
My criticism is not minor, it is a critical blow to his argument. If the Supreme Court really did say that income tax is unconstitutional, they why would the people most familiar with those rulings, and with the best access to the court not change their behavior. If they don't have to pay the taxes, then there is no punishment waiting for them, they would just stop. Presumably, there would be no legal fees for them either (they are more than capable of defending them selves).
Not true. All the money you have when you die, you can keep. It's only if someone else want's to receive it that they have to pay taxes on the amount in exces of 3.5 million dollars.
You pay tax on money you do earn... why complain about receiving money that you did not earn and being taxed on it?

I guess my problem with this technology is that it is too expensive to be used by any but those with the most resources, but least necessary for them.
I was suprised, but they generate only one photon per pulse. Otherwise, your right, it doesn't work.
Right, but it looks like the detector has to be 100% efficient, otherwise, how do you know if you got a zero (no photon) or if the photons just got absorbed somewhere? As far as I know, there no 100% efficient counter (cooled PMTs can be close, but not that close).

Please give it to this guy too...
My monitor at work has this problem. I just taped over the LED and now everything is fine.
I have no idea where you got this idea... there may be some that are auto adjusting, but most you can adjust just like all other lights.
