The problem with password schemes based upon songs, poems, books, etc. is that a sophisticated attacker has access to the same material. Many years ago, when "book codes" were popular, spy agencies kept libraries of common books that were likely to be used by the people they spied on. Today, it would be trivial to build a library of song lyrics and use it as a source of test keys.
I was trained to do electronics repair in the old days, when you diagnosed the problems down at the component level and replaced the bad components. It required substantial amounts of training, a shop with a lot of expensive test equipment, complete technical manuals for everything that the shop repaired, and a substantial inventory of spare parts.
Time is money. It is much cheaper to nuke the problem by attacking it at the highest level. That means that major assemblies get swapped out if they are defective, often the entire unit. For software problems, reformat and reinstall. If you didn't backup your data, tough shit.

I've had good luck with buying quality AM/FM/SW radios, like Grundig's YB400. Even if you never listen to SW, it does a nice job on AM and FM. In general, you get what you pay for. Don't expect good performance from a cheap radio.
A good FM radio costs considerably more than $2. It needs a well-designed RF input stage, frequency-synthesized tuning or a very stable VFO, and good IF filters. Most consumer-grade FM radios turn to shit in a hostile RF environment like found in many urban areas.
Besides the awful playlists, annoying DJs, and excessive number of ads, there's the issue of audio quality. Most FM radio stations aggressively use "modulation optimizers", which are multi-band compressors/limiters. The result is music with no dynamic range and a tonal balance that has little resemblance to the original recording.
I don't think so. You are subject to FCC regulations while you are in San Diego. In the border areas of Canada and Mexico, there are often additional restrictions due to treaties signed by the two countries concerning radio regulation and operation.
The trick is to have the base station antenna mounted on top of a tall tower or building. That is usually more important than transmitter power for long-range communications. The goal is to have a direct line-of-sight between the base and the mobile.
The military uses 225-400 MHz for air-to-ground communications and for navigation aids. That's a bright idea, jamming the United States Air Force. It's not like they could make your life miserable or anything.
Many of the places that most people would not like to live. Limited population densities, limited use of technology, and a government that will ignore the law, for a price.
Call up your local Motorola dealer and they will be happy to let you know about private radio systems that are legal, licensed by the FCC, and have long range.
Do you plan on repealing the laws of physics and information theory?
Regardless of the evil cell phone companies, the RF spectrum is a limited resource. The widespread use of high-power cordless phones would quickly exhaust that resource, and far fewer people would be served than with a well-designed cellular system. Cellular radio technology was developed because the existing technology (high-power VHF/UHF FM) did not have the capacity to support more than a very limited number of mobile phone subscribers.
Digital vs. analog is irrelevant. If it causes interference to a licensed radio service, the FCC can seize the equipment, hit the offender with major fines, and in extreme cases, refer it to the Justice Department for criminal prosecution.
The small businesses profit from accepting credit cards in a number of ways. Extra business from card holders, quicker reimbursement when compared to checks and other non-cash instruments, and lower costs of cash handling. Handling cash has it own costs and security problems.
It's annoying because the credit card issuer's merchant agreement specifically says that the merchant can't require ID for a credit card transaction. Those are the rules. If you don't like it, complain to the credit card company.
You not only have rights, you also have obligations. Part of being a citizen is the acceptance of those obligations. You have to pay taxes and serve on juries. If the Congress decides that it is necessary, you may be drafted into military service. There is no free lunch.
There is a difference between being able to run a new operating system in generic mode and running the new operating system with all of the laptop-specific features that were supported on the machine when it was shipped. Little things like power management, special keys and indicators, sleep/suspend/hibernation, non-standard i/O devices, may stop working properly when a tweaked and customized OEM version of Windows is replaced with a generic version of Windows.
Installing a new release of the operating system often means that every application on that system must be tested, which requires time and money that does not exist or is in short supply. You can't just install a new release of the operating system and hope nothing breaks.
My experience with laptops has been that the manufacturer only supports it with the version of the operating system that was originally installed on the laptop. They have no interest in expending any effort on updating the laptop-specific software to be compatible with newer releases of the operating system. That means that you are stuck with whatever came on the laptop until it finally dies. From the manufacturer's point of view, the "solution" is to buy a new laptop.
The Communist Party should be glad that there are still people who care about politics, even if they have "wrong" ideas. Unlike many of their fellow citizens and party members, who only care about getting rich.
The digital channels can be packed more tightly in the available broadcast bands without causing unacceptable levels of interference. This is because the new modulation techniques used for digital television are much more resistant to noise and interference. With digital television, you can put more stations in the same band or the same number of stations in a smaller band. Each station still uses 6 MHz, there is just less unused space between stations.
The end result is that the FCC is going to recover spectrum by lowering the top end of the UHF band, as they have done several times in the past. That is how the 800 MHz cell phone bands were created. The original plan also would have recovered the VHF bands but that was killed by lobbying from the broadcasters.

It looks like a modern version of trompe l'oeil, without all the pesky work involved in learning how to paint.

You have to use the right species. Some species aren't too particular about not eating healthy tissue.
