I find it highly entertaining to read all of the knee-jerk responses that say that anyone who buys Intel is an idiot, a victim of Intel propaganda or that AMD is the target of a dark conspiracy. In the real world, there are often other considerations in selecting a CPU other than game benchmarks. If you like AMD systems, fine. That doesn't mean that anyone who makes another choice is a luser.
Go ahead, mod me down. I've got plenty of karma points to burn.
Regardless of the operating system, how can you make a high availability system out of a PC? PCs are designed to be cheap, not reliable or maintainable.
When I think of high availability, I think of systems with redundancy and hot backups that can switch to alternate hardware in a few seconds if a failure is detected.
Try using an old version of UNIX, like V7. It was still a research operating system and the philosophy was that users were mature and trustworthy enough not to do stupid/hostile things. There were many ways for a user to screw up the system. The program crashes when you feed it an input line of 4096 characters? Well, don't do that! That philosophy becomes untenable you put the system on a public network and give accounts to large numbers of immature college students.
The government, through the judiciary, can refuse to enforce terms of private contracts that are against public policy. This is how discriminatory restrictive covenants on property deeds were rendered ineffective. The deed may say "the property may not be sold or leased to Blacks or Jews", but the courts will not enforce that restriction. See Shelly v. Kraemer.
My company has an expensive dedicated digital telephone network in house, and I can't imagine that it does anything that a standard Ethernet couldn't.
There is one important thing that your expensive digital phone system has over standard Ethernet, reliability.
Most telephone systems are designed to be reliable and fault-tolerant. Most data networks are designed to be fast and cheap. They are optimized for different goals.
You don't need the ISO or a CD. You can download two floppy images, reboot your computer and install from the network via the ftp install option. It takes a while over a 56K modem but it does work.
The Shuttle can't be automatically landed. The landing gear can only be deployed by the crew. Landing the Shuttle without the landing gear deployed is considered to be non-survivable.

After everybody started hijacking airplanes to Cuba, the FAA started putting armed sky marshals on selected flights. I'm not sure if they still do that.
If you visit the military installations on Hawaii, such as Schofield Barracks, home of the 25th Infantry Division, you can still see bullet holes in some of the buildings from the Japanese attack on Pearl Harbor. They were intentionally not repaired.
It's standard procedure in the U.S. Army to order "route step" (unsynchronized marching) while crossing a bridge. I suspect the bit about sympathetic vibrations causing a bridge to collapse is mostly an urban legend, at least for modern bridges. This

describes a structural failure of a hotel walkway during a dance. From what I remember, the cause was found to be inadequate design and construction of the walkway.
Another problem with the AM and FM bands is that the only politically acceptable digital broadcasting system seems to be IBOC (in-band on-channel). This means that broadcasters would use their existing frequency allocations to broadcast an additional digital signal along with the analog signal. This keeps the power and money in the hands of the existing broadcasters and keeps out the riff-raff (i.e. you).
It isn't "their spectrum" in the first place. They hold licenses to broadcast in the public interest and convenience. The licenses are not a property right, they are a privilege that can be modified or terminated at any time. Sometimes they forget that.
You can get more power out of nicad batteries. They have lower internal resistance than lead-acid batteries. When I was in the military, I saw them used for high current applications like starting helicopter jet turbines and rotating turrets on armored vehicles.
I think the problem is that email is too cheap. There is no incentive to limit its use to important matters. In a corporate setting, you get email to the whole company about J. Random Loser being appointed assistant manager of widget inspection, baby showers, retirement parties, lights on in the parking lot and other trivia. These may be important to small groups of people, but they get sent to everyone. There is no incentive to limit the distribution to the people who really care about the subject of the email.
I recently read "The Case of the Toxic Spell Dump" by Harry Turtledove. It isn't great literature, but I thought it was entertaining. The book is part mystery, part fantasy and part science fiction. It is set in Southern California, in an alternate world where magic has taken the place of technology. The hero is an employee of the EPA (Environmental Perfection Agency) who is investigating possible leakage from a toxic spell dump. Like technology, magic produces hazardous waste that must be disposed of properly. Technology still exists, it's just that magic is cheaper and simpler for many tasks. Nuclear weapons have been replaced with megasalamanders. The military has its own secret and sophisticated magic R&D program.

It gets worse. I've seen Windows 9x used for servers.
There are perfectly good reasons to buy an Athlon or a P4. Which one to select depends on what your needs are. There is no "wrong" choice.

Let's see, ESR is "much worse" and "taking political advantage of the situation", because you strongly disagree with him. How convenient.
Right. The slut was asking for it.

It's called satire.

The space pen's development was funded by a private company.
These days, your bank account could also be accurately described as "just bits on a server".

My guess is that it is a cheap form of stealth, to reflect radar pulses up instead of down.
We are already dropping concrete bombs on Iraq's air defense installations. A water bomb should be easy.
