RAND did a report on the use of space based weapons, Space Weapons Earth Wars. It has some interesting analysis of the practicality and performance of space based kinetic energy weapons, both artificial and natural. See Appendix B. A tungsten sphere with a radius of 1 meter, entering at 11 km/s and 60, will retain 34% of its kinetic energy and 99% of its mass to impact. The impact will release the equivalent of 422 tons of TNT in kinetic energy.
With large objects, the presence of the Earth's atmosphere is irrelevant. It causes some minor heating on the surface of the object. It doesn't slow it down or deflect it by an appreciable amount. Try running a car into a brick wall at 200 kph. Now put a thin layer of foam rubber on the brick wall and repeat the test, see any difference?
Windows 98 has the advantage of allowing an application to directly access I/O ports and memory mapped registers on I/O cards. This means that you are not forced to write a device driver to do I/O. The system can be setup to run a single application, with Windows providing the GUI and network stack. The end-user only sees the provided application, and is never given the chance to run any other programs or to modify the system.
Although they will probably use IP to transport voice data between their switches, that does not mean that any of the data will travel over the public Internet or that the end users will use IP. All this does is change the design of the subnet used to transport voice data in between toll switches, not the interface between the toll switch and the end user.
They were lucky. I remember an accident in the southern United States where a DC-9 tried to fly through a severe thunderstorm with hail. Both engines were destroyed and the plane crashed, killing everyone on board.
One of the problems is that a liter of water doesn't weigh the same in different places. The isotopic composition of the hydrogen and oxygen varies by location. A liter of water isn't a uniform collection of 1H and 16O atoms. There are varying amounts of 2H and 18O.
A 150 grain bullet from a 30-06 rifle can reach 9330 feet (2844 meters) when fired straight up. Julian Hatcher, who became the Chief of Ordinance for the U.S. Army in World War II, investigated this and many other ballistics questions.
The charging scheme in the USA actually predates analog and digital cellular telephones. Back when a mobile telephone was a suitcase sized Motorola FM radio transceiver in the car's trunk, the owner of the mobile telephone paid for the airtime of all calls placed to or from his car. All calls were placed through a mobile operator who was responsible for setting up the calls and filling out a charge slip for each call.
A friend who used to work in Pakistan told me that they had continual problems with some of the more industrious local residents "recycling" sections of their land-based cable links. Every time a link went down, they would send out a truck to check for missing cable segments.
Reliance isn't having problems with its technology, it is having political, business and regulatory problems with the rollout of their service. The incumbent service providers are trying to use all means at their disposal to prevent Reliance from gaining a foothold in the mobile communications market. Telecommunications companies are typically run by lawyers and accountants, not engineers.
Ethernet is CSMA/CD, not CSMA. The collision detection mechanism arbitrates access to the medium, it is not there for flow control. Collisions are not bad.
There are certain types of algorithms where a 64-bit chip will be twice as fast as a 32-bit chip, assuming that the instruction times are identical. These algorithms are based on doing large numbers of single-bit logical operations in parallel.
Many years ago, I had the experience of reading the source code for the device drivers in a multi-user DEC operating system. It was very enlightening. The engineers who wrote the drivers assumed that all of the hardware was buggy, unreliable junk. They wrote code that expected the hardware to fail or lock up, and took the appropriate corrective action. If an operation timed out, the driver would reset the controller and reissue the command.
UNIX had the opposite philosophy. The hardware was expected to work perfectly. This led to situations where a DEC operating system would run reliably on a particular machine for months at a time and UNIX would crash within minutes on the same hardware.
ASICs and DSPs are two different categories of chips. ASICs are highly specialized for a specific task, say a MPEG-2 encoder. DSPs are general purpose processors that are optimized for number crunching.

If you live in the USA, the Bill of Rights enumerates your right of free speech. That does not make it an absolute right. Try exercising your right to free speech on my property and I will have you arrested for trespassing.
You are assuming that the average citizen is interested in listening to "peace and justice" advocates, where "peace and justice" is a modern code-word for flaming leftist, and has little to do with peace or justice.
Most of the so-called Independent Media Centers are left-wing circle jerks and outlets for propaganda. They make the Fox News Channel look fair and balanced in comparison.

Do you know why Rush Limbaugh and Fox are popular? No, it isn't because their audience is stupid and/or brainwashed, or because of a conspiracy by "The Man". A large proportion of the American public is conservative and likes their shows. If Noam Chomsky could get the same ratings as Rush Limbaugh, the corporate whores in the radio industry would broadcast his show coast-to-coast. Their agenda is making money, not pushing a particular ideology.
Old bills and coins are still legal tender, although they are worth more than their face value as collector items. You can no longer redeem gold and silver certificates for gold and silver, but the certficates are still legal tender.
"All coins and currencies of the United States, regardless of when coined or issued, shall be legal-tender for all debts, public and private, public charges, taxes, duties and dues."
High-end systems, from IBM and other vendors, are capable of transparently dealing with RAM failures. They can detect and correct errors, even if caused by the total failure of a DRAM chip. They include built-in spare DRAM chips that can be electronically swapped for bad chips. The memory boards can be swapped out when it is convenient for the customer.
I own several books that give step-by-step instructions on how to commit acts that are felonies under federal law. The authors and publishers have a first amendment right to publish this information, even if acting upon it would be a crime. Why should a book on hacking the xbox be any different?
You might try a better radio. Radios designed for shortwave listeners, amateur radio operators and commercial/government users, are usually much better than the typical off-the-shelf consumer units. They are less prone to front-end overload and they have better selectivity and shielding. If one station is the cause of your problems, you might try putting a notch filter (band reject) filter in your antenna feed line, tuned to the frequency of the offending station.
