You are right, as actually tested by a colleague using a power meter. With his normal, mostly white, desktop - 26W. Unplug the video so the monitor goes into "No Signal", which this particular monitor did not timeout - 28W. Not a great difference, but definitely going the opposite way to TFA.
I read it - or at least I recall reading it - somewhere in one of Stephen Jay Gould's popular books. That gives you only about a dozen hefty volumes to search through.
Unless Amazon's patent specifies exactly how they make it scalable, that is a matter of the implementation. If they have so specified, then the patent covers more than distributed storage with web services interface - in which case it is justified. But it appears that this is all they have patented, so they have locked people out from producing better (cheaper or even more scalable) lookalikes.
Poor fellow - quoted out of context as always. What he actually said was words to the effect that "Anybody who refuses my budget increase must think that everything that can be invented has already been invented" i.e. the exact opposite of what eveybody thinks he said. He was applying to Congress for a bigger budget.
Both are right, but the previous point is, IMO, more right. The amount of flying you can do depends upon the mass of fuel loaded and then the mass burned. Even before the plan has built, the Specific Fueld Consumption of the engines is specified in thryust generated for mass flow of fuel.
Actually, it is a Latin word, meaning "slime". But since it is a collective noun, it probably does not have a plural, just as we rarely refer to "slimes". It is probably thiord declension, in which case the plural is virus, rather than first, which would give virii.
Edges chip, as it says in TFA. As it is, the thing is "only" accurate to a few hundred atoms, so exact crystal boundaries don't matter. When they have another couple of orders of magnitude of accuracy, the suggestion you make may be sensible. For the moment, it is just a lot better than what has gone before.
But when wear and tear have damaged the first one (and they are making two), you can use the same process to make another one, which will, because it depends only on the mass of the silicon atom and the diameter of the sphere, the same (to the accuracy of the sphere). And you can tell someone on the other side of the world, or the universe, how to do the same without having to fly yur lump of metal across the world.
While the Earth is very round compared to most things, it is not round compared to these. The spheres on Gravity Probe B, previously the nearest to perfect spheres, were reported to be so round that if they were scaled to the Earth, the maximum deviation from abyss to mountaintop would be 12 ft. These are even rounder.
As TFA said, the reason for a sphere is that anything with edges can get chipped. The accuracy of the sphere is 35nm, which is still significantly larger than the crystal lattice of silicon, which is of the order of 0.1nm. The variation on the diameter of the sphere is therefore of the order of 350 atoms.
The second is not defined n terms of the speed of light. The second is defined by a certain number of cycles of the light emitted by a particular transition of the caesium atom i.e. in a manner than can, in principle, be replicated anywhere in the universe. The objective of this is to define the unit of in terms of the mass of the silicon atom. The speed of light is them used to give you the unit of length, and all three fundamental units are defined in a way in which, for example, we could transmit them to an alien civilisation so we could talk meaningfully about physics.
And you are you going to determine if you have x atoms? It will take a long time to count them out. That is the point of this project: to create an object, the sphere, whose number of atoms is known as precisely as possible. If it is a perfect sphere, its volume is precisely known. And if the crystal spacing of silicon is known (which it is, very well), then you have a very precisely known number of silicon atoms. This means that you have a macro-scale object, suitable for use in a balance or equivalent, whose mass is known in terms of unique natural substance rather than an arbitrary lump.
But this does not provide so much protection. A Raid 50 consisting of two Raid 5s ganged together in Raid 0 is still vulnerable to a double failure in one half of the array, weareas a Raid 5 DP could handle any two drives failing.
Except that it is possible to have dual parity RAID, and the code is available for Linux. In this case, you need two disks to fail before you lose your data. However, calculating the data for the second redundant disk is *much* more CPU intensive than the first, so you don't want to do this unless you really, really, value your data or have a lot of cycles to throw away. Some commercial dedicated Raids also do double parity.
Almost as bad as the engine of my car. Lumps of metal hurling themselves up and down hundreds of times a second, accelerating and braking over and over again. Tolerances of a hair thickness running at hundreds of degrees and expecting tom be kept oiled without burning the oil. Fires meing lit ans extinguished ijn millisecond. Camshafts? Valves? Timing chains? All expected to keep in exact step? It'll never work, I tell you. And if it does, it will only run for minutes before something in the whole haywire mess breaks.
No. Terrestrial is catching up with Hubble in the visible, but terrestrial cannot see into the IR - full stop. SD0o there is much more untapped science in the IR than in the visible. Our preoccupation with the visible is highly speciesist. Anyway, you won't lose your pretty pictures of exploding galaxies: most of them are false colour or so highly processed as to amount to false colour.
The cost of the JWST is about the same as two Stealth bombers or less than a a dozen Strike Fighters. While I know there is not a straight tradeoff, I regard the Value for Money as fantastically better.
Hasn't this already happened to people who are on the "No Fly" list because they share a name with someone the authorities suspect (maybe rightly) of being a terrorist?
I read a report recently on a proposed Bosporous tunnel between the European and Asian halves of Turkey. This is a notoriously active zone. But the report reckoned that, provided you don't actually cross an active fault, a tunnel can be made proof against all expected earthquakes. This tunnel would run about 20 miles from the big fault across northern Turkey which has caused so many earthquakes in past decades and is expected to cause a Big One in Istanbul soon.
On the Chinese problem: at least they mark their pages where censorship has occurred, unlike Yahoo and MSN who do it silently. And censoring the pages of google.cn was the only way they could get inside the Great Firewall. The Chinese language version of google.com is uncensored - but residents of China with insufficient net-fu cannot see it. IMO, the path Google chose was the least evil in an evil world. Either Google with censorship visible, or other search engines (particularly including Chinese government ones) with censorship hidden. At least the Cjhinese paople can wonder what is being hidden.
As for collecting data: it is not evil until they use it for Big Brotherish purposes. Like fire, data is neutral. You can use it to warm yourself, or to burn heretics. If Google start selling personal data, or using it in house for intrusive purposes, they are not guilty of evil. Not all people who buy guns do so to shoot their wives.
Detroit autoworkers have been getting laid off for decades, and Detroit and the traditional US Big 3 are in crisis. I don't see the crisis at non-Big 3 US plants, not at overseas plants. CS jobs are, to some extent, being offshored - but that is not what the original article was about - it was about CS as a concept. And I think the offshoring, while real, is overstated.
No particular company has a right to live for ever - see Borland, Netscape etc. But because CS jobs move from the old companies to the new ones, it doesn't mean they are disappearing. Google employs a lot more CS people today than it did five years ago.
A lot of us buy off-the-shelf cars. That doesn't mean that there are not a lot of "real" engineers developing those cars. There are also lots of small specialist marques, customizing shops and so on, using real engineers. And - Shock! Horror! - people sometimes work on their own cars without employing a professional. Software is the same
The number of people who make their living by making computers do thing is expanding fast. Not all of these are Computer Scientists. The number of Computer Scientists is probably still rising, or at least staying the same. But they are getting hidden in a huge cloud of configurers, web designers and so on. And so it should be - computers are becoming standardized and reliable. But it is only relatively, not absolutely, the CS is disappearing.

Lighter, cheaper, and more likely to save your life, you could buy a smoke hood.

They have already been locked out from the name gmail in the UK, and have to give googlemail.com names to UK users.

This is the most perfect crystal ball ever! We can see the future better than ever before!

Something like using "Yankee" or "Yank" to refer to all Americans. But we wouldn't do that, would we?
