AMD also has to deal with their past history of an association with flakey motherboards and chip sets. I don't care if it is the fastest, or cheapest, if it doesn't deliver rock-solid reliability, I'm not going to buy it. That's something that many of the AMD fanboys don't understand. They care more about overclocking, neon lights, and fps in the latest games.
"Pornography" is legally meaningless. It covers a great deal of material that does have first amendment protection. It's usually used as a rhetorical device to imply that the material in question has no social value, and that anyone who defends it must be depraved.
You might have better luck with ranging based upon propagation delay. If you know the locations of the base stations, and the transmitted signal contains a time reference, you can measure the delay between the transmitter and receiver. This assumes that each node has an accurate clock. Another approach is for the base station to transmit a carrier modulated by a PN sequence. The mobile station takes the output of its receiver (the PN sequence) and feeds it to the modulator in its transmitter. The base station compares the transmitted PN sequence to the received PN sequence to make a delay measurement. After subtracting the known delays in the system, this gives you a round-trip delay measurement.
GPS receiver technology has improved dramatically in recent years. New receiver designs have greatly improved the sensitivity of GPS devices. The new receivers can acquire the GPS signal in many places that were hopeless with older receiver designs. Much of this research was spurred by the need to identify the location of cellular phone handsets for emergency services. It will take a few years for the new chips to show up in production hardware. When it does, you can expect GPS to work in many more places than it does today. Making it small enough and power efficient enough for your wrist watch may take a bit longer.
Democracies often have similar problems. Try driving in Washington, D.C. The mayor and his cronies have low-numbered plates. Then there are special plates for Senators, members of Congress, diplomats, diplomatic staff, etc. These people are almost immune from getting tickets. They might get temporarily detained if they mow down a troop of girl scouts while drunk. They park when and where they please. I used to live near an embassy and they would park their cars on the sidewalk of the street I lived on when they were having a party. The police couldn't ticket or tow them.
In many places, they can get reprimanded, or even fired, if they get too many complaints about their driving.
If you see a cop do something really stupid, make a note of the car number, location and time. File a written complaint with the police department.
Some departments have an institutional culture of ignoring traffic laws and department procedures in non-emergency situations. Others insist that their officers set a good example for the public.
Inspection stickers are easily forged or illegally transfered from a compliant vehicle to a noncompliant vehicle. I've seen people swap whole windshields to get a "tamper-proof" inspection sticker on their car.
I'd run random spot-checks and seize any vehicles that were missing the required equipment. That gets people's attention.
Nice rationalization. "It's not highly skilled drivers like myself that are the problem, even though we routinely ignore speed limits, and other traffic laws, it's those damn slowpokes who get in our way."
More than you might think. I've seen an increasing number of devices that come with switching power supplies, either internally or as a replacement for "wall wart" power supplies. Improvements in ICs for switching power supplies have made them cost-competitive or cost-superior to many traditional power supplies. See here for an example.
1+ kW processors used to be common, back when processors were built from hundreds, or thousands, of chips. Cooling wasn't that difficult. You just needed a source of chilled air at positive pressure. The power density was low, so all you needed was a steady flow of air over the IC packages.
Modern switching power supplies are much more efficient than the old linear power supplies. Some are better than 90% efficient. How much copper are you going to have to buy to keep line losses less than 10% at 12V?
Thermal coefficients of expansion. Changes in physical and electrical properties of materials. Reductions in chemical reaction rates.
Materials become brittle. Batteries don't work. Lubricants congeal. Differing thermal coefficients of expansion cause poor contact or mechanical failure from stress. Parameter shifts in electronic components can exceed design specifications.
It's a real problem. That's why a lot of equipment is installed in an insulated box with a thermostat and an electric heater. Extreme cold can cause permanent failure.
I've seen the same thing in many other organizations. There isn't any funding to hire real systems administrators, so it gets done in an ad-hoc fashion.
Get off your high horse. Plenty of Europeans are drinking Budweiser and other American brands. It just goes to show that beer snobs can be found in every country, while the common man drinks what he pleases.
It doesn't have to be that way. They can put 39 Mbps of data on each 6 MHz digital channel. That's enough for 2 or 3 HD video streams, or a bunch of high quality SD video streams.
My local PBS stations multiplex multiple SD programs on a 19 Mbps over-the-air channel during the day. I was pleasantly surprised by the quality of the video.
You may get "upgraded" to digital cable whether you like it or not. Digital cable makes much more efficient use of the bandwidth on the cable distribution system. Some cable companies have said that they plan to remove all of the analog channels from their systems. They are waiting for digital STB prices to fall to the point where they can afford to give them away to their analog customers.
If you want to test the proficiency of pathologists, you are going to have to send them live samples of real diseases. The trick is to not select samples of diseases that have an excessively high risk of starting a deadly epidemic if accidentally released.

Thank you for proving my point. I say I want "better". You say it's "faster" and "cheaper".

No. It was designed to make DARPA research more efficient by improving communication and sharing resources and tools.

Lots of interrupts and context switches.
The human brain has a very good liquid cooling system. It dissipates about 25 watts.

That's why I always keep a can of electron grease in my toolbox. It helps to prevent lasers from overheating and seizing.

You forgot the bit about the hamsters being accelerated through a Higgs field.

Hollywood does get it right on occasion, see Tora! Tora! Tora! vs. Pearl Harbor.

Great! Will it will run OS/360 MFT? Time to dust off those JCL decks.
