Well, from experience, it is the case in France, Italy, Spain, Switzerland, Austria and Germany. I couldn't say about the Netherlands. But, yes, of course it's a generalization.
I've seen instant coffee in England, now you can argue whether it's in Europe or not.....
In most of continental Europe, if you ask for a cup of coffee you get a watered down expresso, and it comes in a cup that is approximately the size of the "cup" you see on your pot. Drip coffee is almost unknown here and viewed with universal disgust. Can't figure out why; I prefer to have a longer drip coffee than to have a expresso and add so much sugar to it that it barely tastes coffee like many do.
Of course, when given the choice of what size they use to define "cup", manufacturers will choose the one that allows them to claim a higher number, even though no one uses a coffee pot for expressos.
I guess the price drop is news, although my guess (the intro screen discouraged me from RTFA) is that the real real news, since they are talking about it in the context of photonic, is that they have integrated the device on a chip.
Am I the only one to actually like the present system? I like to see the sun when I wake up in the winter, but there's no point in having the sun rise at 3AM in the summer, so I move the clock to have the sun later at night. I could achieve the same by moving my working hours, but moving my clock twice a year is much less of a hassle.
The fidelity necessary for QKD to be provably secure depends on the axact protocol used. BB84, the most common protocol, can withstand a 11% error rate. Quantum cloning is one of the most obvious attacks, but not necessarily the best one.
Also, as other commenters said, quantum cryptography is only secure if the key is used in a OTP.
Following that point of view, we don't know that black holes exist either. However, we have observed (in cosmic rays) particles with more energy than the particles at LHC will create, and these particles did not destroy the earth.
The most things a typical person can easily remember in the short term is seven.
A typical person can remember seven things, which is different than up to seven. For example, a typical person can remember the sequence 37, 65, 12, 13, 12, 98, 4, but probably not more. The Pirahas, on the other hand, probably cannot remember series of number higher than seven because they have no word for it. 65 is a word, therefore one thing, but 65 objects are 65 things, therefore exceeds the 7 limit.
Which means, the mental effort required depends on the word used.
Google Trends plots the frequency of queries, i.e. the number of times information is asked about a subject. Gootrude plots the number of pages found, or the quantity of information google can retrieve on this subject. These are completely different.
Worst. Graphene being 1 atom wide? Graphene is a planar sheet with a honeycomb lattice. I fail to see how you can make a 1 atom wide honeycomb lattice. Unless what they mean is 1 atom thick, but then this is a 1 atom X 10 atoms X 10^6 atoms transistor. This isn't quite the same thing.
What is sent is a qubit, which is a whole lot different than a bit.
The photon could also be sent before the data, and then you would use quantum teleportation to send the information on this photon. However, this is not what they have done here. They're pretty much just sending a photon, and that's it.
However, in this case, what is really interesting is that they were able to detect a single photon, which is a lot harder to do than detecting normal pulse of light (or radio for that matter) containing gazillions of photons. This is necessary for a lot of things quantum, but in this specific case, there is nothing really quantum about it.
Yes, it is. The problem is not that the the's and of's aren't a problem. The problem is that this particular problem can be described, analyzed and solved in a single sentence. For example, the sentence
Words like "the" and "of" pretty much clutter non-smart registers. does the trick. For completeness, maybe I might add "Registers that ignore words like "the" and "of" are more efficient than those that doesn't". If I really wanted to put myself into it, I guess I could do some research and say something like "47% more efficient", but when implementing an algorithm that you know will make your search engine better takes less time than figuring out exactly how much better, you can skip the study part and implement it already.
They wanted to build three millions of those. They can only build 700k because they don't have enough money. Buying one gives them more money so they can build more of them. Each laptop bought means one kid will get a laptop that he wouldn't have got otherwise. Plus, it creates more jobs. No one loses here.
Who told you I was looking for a general purpose computer? I'm looking for a low power-consuming, portable, low-end computer that will have a browser, wifi, a pdf reader, a word processor and possibly Skape (can the XO run Skype?) and that has a real keyboard and screen and is not a cell phone. These things exactly fill the niche between low-end laptops and PDAs. I could get the same price/performances with an old laptop, but chances are that the battery will be used to death and unreplaceable and that I'll be stuck to the wall plug, or that it'll be full of dead pixels, or whatnot. New, even low-end laptops are not available for 399$.
Oh, and your points #2 & #3 also apply.
Or the rest of the world for that matter. Are we not good enough to buy those? I can see the teen from a third world country who worked and saved his money for years to get one of those, only to be told "Sorry, you can't buy it! You need to be given it, and your government has chosen not to give one to you!"

Yes, and for only 279$, you can get a report that does basic maths. Typos included.
Even telecommunication wavelengths APD have been available for a long time. They are mostly used for single photon detection.

Microsoft is an excellent mouse-making company. It's a shame people keep complaining about their failed OS sideline.
Well, I've always used ps then kill PID. What would kill %1 do?

A EEE Pc can hold at 3 hours without problem, probably 4 if you turn the screen off. 6 hours is really optimistic though.

Apparently 1080 allows you to display at 8000x8000 now. That's a use.

I suspect you cannot even begin to comprehend just how wrong you are. But you are. Trust me, you *are*.
Have you ever watched Formula One racing? Would you find it more interesting if the car was "organically attached" to the driver's body? Why?

yeah, well....my laser is bigger than yours!!!!!
(It probably is - in volume.)
State-of-the-art really expensive detectors have dead time of about 50ns. Typical dead times are more like 10us.

No, there are twelve. However, I would expect all of them to use the same blacklist provided by the government.
