Redundant - no, you can not do that on the fly: your local network use it often. My ISP (sort of a DSL, LAN over phone within aparment complex) checks for it - stops working if I swap a NIC. My office LAN gateway same way - there are reasons not to allow for easy MAC changing on a LAN.

Once I get that baby up and running, I want to be able to restore it whole.
Why? Keep/home separate and backed up, if something wrong, nuke the / and reinstall. In RH (which I use) run autorpm to restore upgrades. It is faster then from tape. (Well, I have and NFS image of the CD, kikckstart diskette and a mirror of all updates again on network. - I do not care what guys in the group did to there system - 15 min and they are back in business - remember there backups can contain the very source of the potential troubles...)
The only things that are needed to be backed up on your personal box are files that you type in with your hands. I do not think you can type fast enough to make a dent even in a 1Gb tape. The rest on your 1Tb hard drive are: a)applications and OS - which are faster to get reinstalled b)Media content (your CDs) that are fault resistant by itself - your CD content has a great deal of redundancy - and can be reinstalled as well. The only need for 1Tb backups are in Tb size database business. For that 2K for DLT drive is not a really big deal.

Actually, it is still very much unknown how RF waves affect a human being. Effects can be pretty weird. But nothing too obviously damaging when the power is too small to heat you up.
Anekdote (but true): When first radars appeared on Russian navy ships, sailors found an ingeneous way to prevent accidents during they stay in port cities. Before disembarking they were standing in front of the antenna for a while - to heat up their testicles, what makes you temporarly sterile. Then off from the ship for some good shagging. The practice was banned soon, of course. These guys were a subject of tests later on, no long term adverse effects other then those of heat were found.
Processor does have enough power to produce damaging radition. But I believe its emmitance is kept low buy design - big reason being to keep down interference and cross-talk: big problem in high frequency design. Do not worry too much.
Why 128-bit? Because if I'm going to have to throw always all my existing technology and go through another period where everything I need to run is considered "legacy" then make it worth my while and jump right to 128-bits! 64-bit is obsolete,even for game consoles. Hell, there are Windows CE portables can have 128-bit Hitachi processors (although again, nothing else in the unit is 128-bit).
It transistor count, my friend. Athlon has 22 millions. Make it 128bit - it would be 88 millions. Two big of a die. Consoles can handle that cause they are simpler.
Other reason is that you would not see too much of a performance increase - 128bit is good if yyou can do a lot of things in parallel - like in SIMD code. Great for specialized graphics chips, not so for a general purpose ones: if you spend you time adding small integers and pushing data in/out memory, it would not help when you integer is 128 vs 32 bit (unless you need >4Gb big address space). Not worth it now.
BTW Athlons have 200Mhz bus, scalable to 400.
Other way to improve in SMP is transputer type processor interconect - like in the next generation Alpha.

Relax. It does not just "start emitting", though emmitance does go up as GHz^4 : pretty fast. Remember that FCC numbers on your equipment?: they mean you are safe. It is being tested for.
You CRT monitor is a much bigger source of troubles. Let's hope that 20inch LCD will come down in price before I go blind...
Don't expect to see beowulf support in your standard RedHat any time soon. According to US export laws, beowulf-capable systems are, for all intents and purposes, munitions.
Yeah, and you can buy a CD with such a system on any street bazaar in Russia.
Stacking bags with explosives under apartment building difficult? Heard of Moscow recently? Or parking a truck in front of a federal building. I would say for indiscriminate terror, lack of guns will lead to far more bloody solutions. Think what would happen in that two dudes had no guns, but just decided to explode the school. Actually, they had a good chance not being caught at all.
... there is a bunch of "technology" companies, that have nothing but lfucking lawers on stuff, who own a few patents, and just sue. They do not produce anything, so they are not interested in cross licensing at all. ... They should be publicly hanged.
Bullshit. Natural science research involves sharing ideas in the same fashion as the Open Source software and it has nothing to do with communism and, I would claim, is quite succesful in the last few centuries. You can get a scientific journal and develop an idea introduced by somebody else without any permissions whatsoever. That coexists quite happily with proprietory technology development. The same with software, now there is common "science" part, and "technology" proprietory part. Principles of knowledge sharing and peer review are much older than communism. That's how human culture works.
... the first area where the idea of free information sharing, peer review and freedom to use and improve on the work of other is used. Millennium of natural science research comes to mind. Somehow I would hesitate to label my fellow physicists - "communists" for giving public access to the data from our experiment. Open Source movement is not different. It is just applying the principle developed by generation of scientists to a new area of human knowledge.

Bus (until now) and cache. 128 vs 512 has a HUGE impact for heavy duty code. Especially when you run several jobs simultaneously.
I observe 10 to 15% difference in execution times.. I never claimed it is for general use applications..
