Charging Americans for using other peoples' inventions is pretty easy; it is somewhat trickier for foreign governments to charge Americans for the use of American inventions, but this problem is too being solved, by buying up IP-holding US companies instead of US Treasury notes. IP laws may have been contrived to enslave the world, but as America fades from the world scene, they will end up being used to (further) enslave Americans.
(For those who don't already know this: the AK in AK-47 stands for "Avtomat Kalashnikova," was invented by Mr. Kalashnikov, a Russian, and the Kalashnikov rifle is a quintessential Russian brand. There is even a Kalashnikov vodka. So - don't mess with it, or you might get shot.)
I got out of Physics after they cancelled the SSC (the Superconducting Supercollider, now the stupid trench in Waxahachie, TX) but other people went on to work on the LHC. Christ, that was a decade and a half ago! And now it's done, more or less. If I hadn't quit basic research and gone into software engineering, I'd be so frustrated by now... oh wait... shit!
Nearly perpendicular to the wind is still to leeward. To go to windward, the kite would have to pull the boat towards the wind, acting as a wedge. To do that, it would have to generate lateral resistance, which is not possible with either one string or two strings. It requires a mast.
Fin keels are a fad; before them, ships had shallow keels that ran the entire length of the ship, or leeboards. The problem of providing lateral resistance has many different solutions; not all of them involve an increase in draft.
Without cheap oil, people won't be able to drive to the mall to buy the foreign-made junk, so the need to manufacture it will go away along with the need to transport it. Gains in efficiency are a one-time thing, but energy prices can go on doubling ad infinitim. On the other hand, certain key commodities, and some luxury goods, will always need to be imported, and for that we'll need to move freight by sailpower.
These kites are basically like spinnakers, moving the ship to leeward. This technology has been available since paleolithic times, when a dugout canoe could be outfitted with a rag on a couple of sticks. A major advance was made by the Arabs some 2000 years ago, with the invention of the Lateen rig, which is still just two sticks and a rag, but the rag forms a conic section, and pulls the boat towards the wind. Sailing on the prevailing winds certainly is useful, but these kites won't be anywhere near as energy-efficient as the large steel square-rigged freighters that were used to transport coal and other bulk goods around the beginning of the last century. They had a steam engine, but used it to power the winches to tack rig. That's the sort of thing we need; this kite retrofit is just a stopgap.
Well, there's quite a lot of information on this exact subject here and here.
Once sentence summary: A mathematical model exists which accurately predicted the midpoint of oil depletion for continental US (1970), and if you crunch the global numbers, it looks like the world midpoint of depletion is right around now.
Of course, we will only know for sure after it's passed and we are facing a global oil shortage.
The French have done well with their nuclear power plants -- except for a scare this summer as coolant levels dropped because of the heat wave -- but in the medium-to-long run uranium mining will become increasingly difficult and expensive to sustain. Plutonium is also a fuel, and is more plentiful, but requires new plants, and is also a problem as far as nuclear weapons proliferation. Lastly, the cost of nuclear energy does not include the costs of keeping nuclear waste in secure locations for longer than the expected lifetime of human civilization.
It provides process-shared mutexes under Linux -- but we can already do that with spin-locks.
What about process-shared semaphores in shared memory? There's no mention of those in change log or release notes. You could fake semaphores with spin-locks (and lots of spinning) or use SysV semaphores. So that hasn't changed.
Support for dual-CPU boxes? Not yet, apparently.
The NGPT folks had initially thought that they'd make the PTHREAD_PROCESS_SHARED attribute available almost a year ago, so, if you can hack this stuff, and have time, please help them!
Where I work, we have a tradition of naming servers after famous dead musicians. Routers are named after famous gay dead musicians. Our dev server is an Ultra 450 named hendrix. It sure is more fun, and easier to remember, than things like pdq12345. Based on our experience, I wholeleartedly recommend this and similar schemes.

They didn't claim it moves fast, just that it *looks* fast. And, apparently, it raises funds fast too. Mission accomplished, I'd say!

When it's cold, I wear fleece, and if I still feel cold, I pedal a bit harder.
When it's hot, I drink lots of water, and go just fast enough for the wind to cool me off through evaporation.
It's an amazing machine, the human body!
I don't think that the words "car" and "efficiency" belong in the same sentence.
Driving = squandering resources. Once squandered, you get this.
