Where I live, old people are rarely the cause of accidents. It's mostly young men, aggressive drivers, drunk drivers, inexperienced drivers, and people who are not paying attention to their driving.
There's a reason that my insurance rates are much lower than those who think that speed limits are a plot by "The Man" to take their money, and that they are NASCAR material.
I've ridden in those "commercial airline seats" on military aircraft. The seats were OK, but the deafening noise and horrible climate control made the flights a miserable experience.
One of the reasons that many Americans were reluctant to get involved in World War II was their experience with World War I. After World War I, British propaganda was publicly exposed as a pack of lies, a cynical effort to mold public opinion at home and abroad, and to get America to enter the war. This destroyed the credibility of European news sources with many Americans, who felt that they had been duped by Allied propaganda.
You can't do that to the Mayor. The higher the position, the less likely that the person occupying it was hired based on their qualifications for the job.
Who is going to benefit from this? From what I've read, this was the era in which it was common for record producers to acquire all rights to the song in exchange for a flat fee.
If your local radio station really cared about audio quality, they would shoot the program director and rip out their Optimod boxes. Most broadcast stations in the USA butcher their audio.
One problem is that the SSMEs are not restartable. It's possible that they could be redesigned and requalified for in-orbit restart, but it would be insanely expensive.
It's those traction motors. They are notorious for emitting a magnetic field that is strong enough to erase magnetic tape. If they can move a train, they can erase your tapes. The same thing used to happen to couriers transporting 9-track magnetic tapes in NYC via the subway.
Amateur packet radio commonly uses Bell 202 style modems, which are both 1200 bps and 1200 baud, only half-duplex. I believe they are also commonly used in credit card verification terminals. The Bell 212A was full-duplex, 1200 bps, and 600 baud.
I've done work on recovering data from old analog tapes. You could clean up the signal by running it through a DC-blocking filter, which is a high-pass filter with a very low cut-off, and a software AGC with a short time-constant. Some of the noise can be eliminated with a low-pass filter. There isn't much that can done to eliminate speed variations. The best thing that you can do is to write a demodulator routine that can track the speed variations and has generous allowances for timing errors in the signal. Looking for zero crossings works OK on relatively clean signals. For more challenging material, you want to integrate over the time period of each bit.
Decades ago, I read an excellent book on Concurrent Pascal by Brinch Hansen. I was sure that similar features would soon become a standard part of modern high-level languages. I'm still waiting.
Single threading, like used on old versions of Windows, does have some advantages. It avoids a lot of concurrency related problems that most programmers are not properly trained to deal with. If everyone follow the rules, it's efficient and performs well.
I was recently reading a paper on multi-core processors and the future of programming. It pointed out that many multi-threaded programs work fine until they are run on a real multi-processor system where multiple threads can actually run simultaneously. At that point, strange timing-related bugs often appear that are very difficult to replicate and diagnose.
I don't think so. The problem with the F-117A is that it's designed to deal with radar systems that have their transmit and receive antennas at the same location.
What happened to the good old days when chip vendors would fall over themselves to give you data sheets, application notes, and anything else you might need to use their products in your design? NDAs were for things like information on unannounced products.
I think the problem was that you couldn't express an editorial opinion without opening the television studio's door to every wacko in town. While the original intent may been good, the result was that most stations avoided doing anything that was even mildly controversial.
How would you like it if you owned a newspaper and you couldn't write an editorial without supplying equal space to anyone with an opposing view?
The receiver circuits are much more complex than the transmitter circuits. It has to do decoding for error correction, which is always harder than doing the encoding. The major problem with ATSC tuners has been handling multipath. A great deal of effort and money has been spent on improving the performance of the tuners under conditions of severe multipath. That's why the latest tuner designs work so much better than those designed just a few years ago. Besides R&D and design costs, the transistor count has increased. Despite that, the end user cost has greatly decreased. The first ATSC tuners were more than $1000 and their performance was terrible on real-world signals. The previous generation of boxes cost more than $200. The current boxes are a bargain and a good example of how mass production can drive down costs and prices.
I don't think the situation in Iran will improve until the people follow the example of other countries that took measures to destroy the political and economic power of the dominant organized religion.

The nautical mile makes some sense. It's one minute of arc along a meridian of the Earth.

Bad idea. The Moon has a lumpy gravitational field. This makes it very difficult to keep anything in a stable orbit. Look up lunar mascons.

That's quite impressive for the time. I wonder if it was designed by an engineer or programmer who was moonlighting from a job at JPL.

You mean, give the robot a stick and program it to violently assault its opponent?
Now introducing the 2008 GE/FANUC Thug-o-matic 5000!!!

How about the Ford Motor Company? They were infamous for their heavy-handed interference in the lives of their workers and their families.
That doesn't work when the lineman takes your pair and gives it to a paying customer.
Iraq did have multiple WMD programs. The arguments are about how far they progressed and when they were terminated.

They aren't "much simpler". An ATSC tuner is a very complex device. Only recently have chipsets with good performance and low cost become available.
