Copyright does not apply when the work is created by a government employee in the performance of his duties. When the work is contracted out, a copyright is created that may be assigned to the government by the contractor per the terms of the contract.
I'd vote for (3) Responsibility without authority. You have a whole building full of "important people" and political hacks who believe that rules and procedures are only for the little people.
So they're democratically elected terrorists. How many rockets did they launch at Israeli civilians today? If Mexico was doing that to the United States, Mexico City would soon be glowing in the dark.
High-resolution is great and wonderful, but what about the unwashed masses with older systems? I'd rather see a video play smoothly in medium resolution, rather than see it stutter in high resolution. The newer codecs seem to choke on older systems. My Mac can handle MPEG-2 without problems, but it has difficulty with some of the newer videos.
How so? You've replaced the AC input to the power supply with a DC input, at a lower voltage and with increased transmission losses. Whatever the input, it gets converted into AC in the voltage regulator.
You can get extremely reliable radio links if you are willing to do some research and spend some money. Weather, in a statistical sense, is predictable. AT&T did this when they designed and built microwave relay systems. They installed antennas that could handle high wind loads and link margins were set at levels that could cope with extremely bad weather. The same can be done with satellite links.
How large is that pool of potential upgraders? From what I've read, the vast majority of computer owners never upgrade the operating system on their computer. They stick with what they have until it's time to replace the computer. With Vista's problems, there is even less incentive to upgrade. Some people, like developers, may have to buy a copy of Vista so that they can test their software for compatibility.
I bought a copy of Vista. I wanted to try it out and found someone who was selling a non-retail version at a large discount. It turned out to be largely a waste of money. For everyday use, I'm sticking with XP until Microsoft gets their act together.
Why? Low voltages are inefficient for power transmission. To provide well-regulated power to modern circuits, you need a voltage regulator that is physically close to the circuit. Pick up a modern motherboard and you will see one or more DC-DC converters used to power the CPU and other circuits.
I don't think so. The spacecraft transmitter's frequency is phase locked to the frequency of the signal received from the ground station. Since it can't transmit on the same frequency as the ground station, there's a circuit in the spacecraft's RF system that takes the incoming signal and multiplies it by a constant to produce the outgoing signal. So it may be receiving at 2.2 GHz and transmitting at 2.0 GHz. That's 20 cycles out for every 22 cycles in. The incoming signal is used as a frequency reference for generating the outgoing signal.
Normally, the ground station collects data on range, range rate (doppler), and where the antenna is pointing. The antenna has shaft encoders that give high-resolution measurements of the direction it's pointing in. With some complicated mathematics, this data can be used to figure out the exact position and velocity of the spacecraft. To get a more accurate measurement, data from multiple ground stations around the world is collected and processed. In addition, you already have at least a rough idea of the spacecraft's position and velocity, which was used to point the ground antenna in the right direction, so you aren't starting from scratch.
The range isn't an issue, it's how accurately they can measure doppler. The standard technique is to transmit a special signal to the spacecraft, which retransmits it to the Earth, like an RF mirror. This allows them to use extremely stable ground-based oscillators, like Hydrogen masers. This signal can also be modulated with a PN code to allow precise range measurements.
If you take Economics 101, you might find out that it isn't always true. Sometimes sales drop when prices are reduced. The Wikipedia article on supply and demand has references to cases where the normal rules don't work.
Have you looked at high school graduation rates lately? There are millions of Americans that never received a decent education, and have limited skills. Plus, there are many Americans that are willing to do seasonal or part-time work, such as in agriculture, because they want to earn some extra money. Many of my cousins did this when they were young adults and didn't have an education and a career.
Because that's what the government ordered. You may know that it's a piece of crap that will never work properly, but any decisions on modifications, redesign or cancellation are made by the customer. The customer gets what he wants, even if he is an idiot.
One reason all those crap jobs have such lousy wages is that employers know they can always hire illegals, who are in no position to complain about wages or working conditions. I'd rather pay more and see an American citizen get the job.
According to the professor who taught my astronomy class, the Earth's climate will be tipped into thermal runaway, like Venus, long before the Sun becomes a red giant. Solar output increases steadily as the Sun ages. It's only a matter of time, like a few billion years, before it overwhelms the Earth's ability to regulate its temperature.
The trick would be doing it without killing the battery life, which would get noticed. There's also the issue of unexpected RF emissions being noticed by the user. The speakers on my computer often make funny noises when a GSM phone is nearby and sending or receiving SMS messages.

What's the biodegradability of this stuff? All we need is some modern version of DDT, working its way up the food chain.

Please turn in your nerd card, and quietly exit the room.

Fsck you, you don't know me and I resent you projecting your own prejudices on to a complete stranger.

Interrupt loads can be greatly reduced by switching to a polling-driven architecture. See FreeBSD.

It isn't that hard. You watch the phasing meters and tweak the generator speed until it's in phase with the grid, then close the breakers.
