Have you any idea how much revenue football programs bring in to colleges, both directly through ticket and television rights sales, and indirectly as part of begging alumni for funds?
I suppose there's some chance that those being sued now could in turn sue the manufacturer. It might depend on the particular nature of the contract between them and the manufacturer.
The guy who made the first blue LED won a 1.3 million dollar prize.
Long before modern efficient blue LEDs were invented there were blue LEDs made by various firms, including silicon carbide LEDs commercialized by Cree in 1989 and tinkered with by others, and even a silicon-based blue LED from Sony. They were inefficient and many of them were expensive, so they weren't popular.
The first observation of blue LED action was made in 1923, before anyone understood what was happening. In the late 1960s some blue silicon carbide LEDs were deliberately developed. In the early 1970s, RCA made (but never commercialized) blue and violet GaN LEDs. http://www.sslighting.net/news/features/maruska_blue_led_history.pdf
It's possible to put a whole lot of sophistication into a cubic millimeter (At least several hundred Z80s with current technology, maybe thousands). Put such a device into even a transparent connector and it will never be noticed.
A high gain antenna must be physically large. To a reasonable approximation, the area of the antenna times the power of the transmitter divided by the area of a sphere the radius of which is the distance in question must be greater than the thermal noise power at the specified bandwidth (greater by about 18 or 20 dB to get reliable data recovery, maybe a little less with good error correction). This means a few dozen femtowatts at the receiving antenna for 100 kHz bandwidth.
The choices then become: the receiver is close to the source, or a distant directional antenna is hidden or camouflaged. In either case, that's fine if the computer stays in one place, but if it's portable then the receiver has to be relocated or the antenna re-aimed.
Not impossible, just another difficulty operating inside a foreign land.
You hit the key phrase: masking techniques. Have the switching power supply generate 5 watts of sporadic, random, wideband noise; transmit data with 1 Hz deviation FSK at one milliwatt. You'll detect this how?
A wise or suspicious security specialist would throw out the computer with the noisy power supply just to be safe, but would be quite unlikely to be able to prove that anything subversive was actually going on.
There aren't as many as ten men in the Supreme Court, the White House, and both houses of Congress, combined, honorable enough to do what you suggest. The remainder are split between those who are embarrassed by the publicity and those who don't control it currently but want to.
all the while never actually liberalizing agriculture at home.
I've read all too many examples of tainted food and poisoned toys from China. Inspection isn't without cost, and should be paid for from import duties.
How charmingly naive. You think our allies aren't spying on us, and we shouldn't spy on our allies. Fool.
The NSA shouldn't be spying on US citizens in the US without some good reason to believe they aren't innocent, and then not without a warrant, it's unconstitutional and evil. Outside the US, they shouldn't spy on people they don't have a reason to believe intend to damage the US, because it's ineffective. Anyone outside the US who can be reasonably expected to intend the US harm is fair game, and properly so.
As a side issue, the ends cannot be separated from the means: the means are a part of the end.
How is this modded insightful? For many years, it's been easy to build receivers that are within a fraction of a dB of the thermal noise floor through hundreds of megahertz. (http://en.wikipedia.org/wiki/Johnson%E2%80%93Nyquist_noise describes thermal noise.) Below about 100 MHz, sky noise is even worse than thermal noise.
Doubling the distance at which the signal can be distinguished over noise requires quadrupling the power. Alternately, the bandwidth can be divided by 4. Bandwidth is proportional to data rate. At, say, 10 bits per second, 1 milliwatt can do over 10 miles, as far as the thermal noise floor is concerned. (Note, this is a mental approximation and the actual distance might be much higher.)
Others above have suggested high data rate burst transmission, which requires high instantaneous power but lower average power. This brings a different set of problems. The transmission frequency will have to be high and also the bandwidth; that means the radiation pattern will be uneven and vary throughout the transmitted bandwidth. Getting the whole signal intact is difficult at the fringe reception distance.
Problems do show up. Manmade interference can be much larger than thermal noise. The biggest problem is that no matter what scheme is used for transmission, something has to intelligently determine what data is worthwhile and get that data to the transmitter. Not everything that routinely goes through a USB port is useful, or even intelligible (consider mouse clicks.) Thus, the computer itself has to be compromised - perhaps we can assume the USB plug masquerades as a boot disk to infect the computer?
I suppose it's possible, but I think the difficulties involved in monitoring and sorting through the heaps of received garbage make the idea impractical
Bargain supermarket chains with locations in high crime ghettos find numerous problems beyond the obvious risks of high crime. Inner city expenses are high, and the store has to choose between losing money and coming under political fire for having prices even a little higher in the city store to cover higher costs. The store will be under political pressure to hire politically favored minorities, and nonunion stores will be picketed with the mayor's secret blessing. The percentage of cash customers will be low.
Between the poor profits, the risk of a homicide on the premises, the risk of reputation damage from political attacks, it's just not worth the effort.
Opposition to contraceptives and proper sex education is evil, but it to call it malicious is inaccurate. Opposition to contraceptives frequently comes from religious beliefs, and therein lies confusion too deep to unravel here. Opposition to proper sex education is bad, but is complicated by sex education in government schools being the wrong place, and by some sex education programs being perversion education programs (I mean that in the literal sense of self-damaging=perverse).
FWIW, the history of "family planning" is far from clean, Planned Parenthood was started as a "keep the darkies from reproducing" organization.
Moralism is never pointless, morality is a guide to living, and a proper morality is a guide to living well.
When people are personally responsible, they educate themselves
When people are personally responsible, they have less children
When people are personally responsible, they don't choose whores as an entertainment option
When people are personally responsible, they tend to make above median income
When people are personally responsible, having good sexual education is moot.
Nope, no influence of personal responsibility here.
That's about $160 a week. Daycare for five kids destroys that
OK, Let's play "It takes a village". A group of three poor moms, each with 5 children, get together. Two of them get jobs at Walmart, $160 a week, and pay the third mom $106.66 a week total to babysit. Everyone now has more money, and they're all contributing to the economy. The moms at Walmart get some employment skills, and the one at home dealing with 15 kids probably develops some new skills too. Where is this inferior to three women sitting on their asses, watching Oprah fail at her new business?
Time and again it has been demonstrated that trade benefits both parties, yet still fools decry job outsourcing. It's as if they want to maximize inefficiency.
If you can't make shoes as cheaply as a chinaman, then
you might not be working as effectively as you should
you're being paid too much
you should look for a different job at which you're worth more
you shouldn't try to deprive the chinaman of an opportunity to make an honest living
Foreign trade, unfettered by government meddling, is part of the solution, not part of the problem.

How many people's lives do you wish to use up in tax payments, keeping alive a mass murderer?
Every decision in life is based on incomplete information. That doesn't mean we should be frozen into inaction until all data is certain.
"Judge not, lest you be judged" is the motto of an amoral coward. An honorable man judges, first himself and then others as needed.
Those who make commandments are unfit to command. Those who follow commandments instead of using their own judgement, are unfit for living.
Hey, anonymous coward, show your name when you equate heroes and villains, or be counted among the villains.
Oops! You can't tell the difference, so you don't care.
Initiation of force is evil. Defense against force is good, and the use of force in retribution for initial force is acceptable and just.

Physical access can be subtle. Do you suffer carpal tunnel syndrome? Won't you try my new ergonomic mouse (with embedded spy hardware?)
