Many chips are never designed to meet military or space specifications: the extra certification is very, very expensive and there are design compromises between performance and ruggedness. Furthermore, the testing you suggest for space qualification, if failed, results not in a mil-spec component but a component that has been destroyed by the test. In some cases, samples of a given batch are heavily tested to verify the batch, but those devices are considered damaged and not sold.
Some rad hard type devices are of no interest to consumer design due to the poor performance caused by the compromises involved in achieving hardness. Rad hard devices aren't designed as often due to the small market, and the design is more difficult and takes longer, and certification takes time, too. Thus, the devices are older technology. Additionally, rad-hard parts (the actual transistors inside the ICs) are bigger physically than conventional devices, which also means they can be fabricated on older technology equipment. Thus, with respect to current commercial technology, space-qualified devices are often older technology.
There are many aspects to radiation hardness. Radiation can flip one or more bits, resulting in bad data or program crash. Radiation can cause latchup, which will last until power is cycled; if the design is bad, latchup can fry a part. Rad hard parts are designed to be resistant to latchup. Really bad radiation can damage a part that isn't even powered.
A laptop can live through bit flips, and with luck it can live through latchup, and be functional after power cycling. Spacecraft control generally has to be always on; power cycling in not an option. Thus the design requirements for spacecraft control must be much stricter.
The problem with airplanes is that they don't back up very well. I don't know how smart CFIT systems are, but I doubt that they can warn you not to fly into a box canyon, where sometimes there's no way to avoid a crash.
The types of ultrawealthy are pretty diversified. http://www.forbes.com/wealth/billionaires/list. 2 of the top 5 are software, but there's industrial, financial, steel, and retail. If the 4 Walton heirs in the top 25 were combined, they'd top the list.
According to wikipedia, the wire recorder was invented in the late 1890s, was patented in the US in Nov 1900, and never saw widespread use. Peak use was between 1946 and 1954.
Any company that knows you consulted a lawyer against your previous employer will automatically reject you as a candidate for employment. Nobody likes a whiner and whiners are terribly destructive of morale and productivity.
Mentioned near the bottom of the article's page is a group of 8000 year old trees discovered in Sweden in 2008. This makes them well older than the religious nutcase claim that the universe is about 6000 years old. Thus the article is well within Slashdot's flamebait threshhold, and belongs here.
Paint porn on the inside of an egg which also contains the transmitter. Make a little hole in the egg for viewing. He'll hold it to his eye for minutes at a time.
Frys is a bad place for suckers and fools, but if you go in as a careful and knowledgeable consumer, the benefits outweigh the deficiencies. The bargains outweigh the occasional flaws, and I had no problems despite making perhaps 50 purchases.
Justice applies to individuals and individuals only. If there is something in so-called "social justice" that does not mean justice for each and every individual, then it's not justice and the term "social justice" is self-contradictory. If "social justice" means justice for each and every individual, then the adjective "social" is superfluous, and is being used to confuse. In ether case, use of the term is unwarranted and dishonest.
Supermarket self-pays work, but they're not as effective as you think. Random people are nowhere near as fast as trained cashiers. I've seen 4 automated check-outs all empty while there are lines at the conventional checkouts. The only place I've seen where the self-pay is clearly effective is WalMart.
When people are out of work for so long without a support system in place, they become mischievous
Well, four things might happen: they die, they live off savings, they turn to crime, or they do any legal thing they can for whatever they can get (which is called work, and they fall out of the category.)
With a support system in place, what they do depends upon the nature of the support system. Private charities tend to monitor those they help, and try to get them back into a productive condition. With government support systems, there is much less monitoring, because the government has the perverse incentive of power, so some of those on the government dole turn to mischief because they aren't monitored. Such mischief includes such things as crime, political campaigning, and riots.
The fact that solar power is not a total solution now does not mean it won't be in a couple of hundred years when mined petroleum fuels become impractical, or in however many thousands of years when mined fissionable fuels become impractical. Speculating on the eventual technology is not to my point; we'll find something, whether it's fusion or solar powered reconstruction of petrochemicals. There's good reason to believe than proper use of man's mind will increase individual wealth for millennia to come.
if the next extinction event brings us to a place where launching is not possible
That condition would be something like: everything on earth is dead, the earth has been scrubbed clean down to magma, the sun is too weak to make solar power possible.
Your engineering textbooks contain all the equations, formula, and methodologies you need to learn to get a degree
I vividly remember my acoustics professor pointing out errors in the textbook. If I hadn't taken notes, I wouldn't have been able to identify the particular error later on; If I relied on the textbook I would have been screwed.
Math texts don't always provide derivations, which have to be obtained by taking notes on the lecture. Then study those notes to learn the derivation and pass the test. Unless you're as smart as the guy who did the derivation the first time, possibly after weeks or months or years of struggling, don't expect to be able to do it yourself.
I have a copy, and it's an invitation to suicide. The two primary subjects are making explosives (including dangerous, unstable stuff like nitroglycerine) and making mind-degrading drugs. It's hard to imagine a worse combination. Even the author, in the wisdom of adulthood, has deprecated the book.
Do you understand that the -400% life you consider as a possibility means it would have failed before it was built, and possibly before it was designed?
Your right turn on red example is defective, because he would most likely be hit by someone going straight, through a green light. The guy with green has the right of way, which should be clear to anyone with a legally obtained license.
Increasing wealth inequality will leave the lower class with nothing to spend on entertainment.
Do you stop to think before you post? There are myriad forms of entertainment available to poor persons, and that has been the case back into prehistory when most people were so poor that by today's standards they would be considered to have zero wealth. Modern technology has brought on many more forms of entertainment that can be had extremely cheaply. If you can't afford a deck of cards or a radio, most libraries throw out more books in a year than I can read in a decade. Within 10 miles of where I live there are 20 free music concerts a year, and probably 100 within 25 miles. There are free fireworks displays. The local library has well over 100 "events" a year (mostly preschooler "storytime"), and other libraries are similar. Most towns have recreation departments and maintain parks and organize sports.
If you can't find almost free entertainment, the problem is not lack of money, it's lack of mind.

I'd steer clear of anyone involved in bones and sheep.

The opposite of free trade is slavery. Would you like to explain how slavery is a solution to our problems?

Carbine, perhaps. Carbine does not imply rifling, but it does imply something in the short size among long guns, but longer than a handgun.

Just to raise a finer point: the old USSR required internal passports to move about the country.
