Well, technically, electronics doesn't have a wearout mechanism, so it should be able to last a million years. However, what does it in is mechanical failure - evaporation of volatile componds causing shrinkage of plastics, rust in ceramics and metals and bonding between dissimilar materials. Over time, things tend to crack up, to put it simply and that process is accellerated at higher temperatures. At really high temperatures, above 100 Celsius on the outside, the inside of a component may be 30 degrees higher and then migration of impurities will occur in silicon junctions, leading to faulure.
To protect electronics you can do a few things - keep the temperature down and provide it with clean power. So do run the fans and use power bars with built in spike arrestors and if a desktop machine, use a UPS.
No, don't turn the fans off. You'll actually experience discomfort when typing, since hot air will rise through the keyboard in some spots, burning your fingers. You need a minimal amount of air flow to prevent that.
To get the drive to spin down, you have to stop all processes that are writing to it unnecessarily. The solution is to stop the syslog process. If the machine is working fine, then there is no reason to keep syslog going, then set the spin down time to 2 minutes. That will also increase battery life by a large amount. I do that on my Notebook. Using a RAM disk won't make any diff - most things end up in RAM pretty soon - the memory manager on modern UNIX systems will take care of things for maximum performance, so you don't need a RAM disk.
I am presently trying to quiet down a MiniITX machine. It has a pair of howling fans in it. I found that a 47 Ohm resistor in series with the fan will reduce the noice to a whisper and still run the machine nice and cool. So, I had to do some measurements.
A 1 inch miniature fan uses about 60mA at 12V. So running at full tilt, it consumes about 0.72W of power. The minimum setting where it will still start reliably, is about 6V at 50mA, so the power is about 0.3W. So, from that you can see that the power consumption of miniature fans is negligible - almost nothing.
The performance of the little fans vary a lot, but the power consumption of even the worst fan I measured, is still negligible. I am actually typing away on this little machine right now, and I think one fan needs a bigger resitor - still too noisy - need to turn the soldering iron back on...

Automatix doesn't break any laws. It is just not compatible with the GPL. That is why you have to download and run it yourself, Canonical cannot include it in the default install.
All I can think is that you haven't actually used Ubuntu, Mandriva, Xandros, Suse, Fedora or any one of a whole zoo of easy Linux systems in the last five years or so. installing software on any modern distribution is super easy. I don't think it can be made any easier.
You don't have to launch them - put a nuke in a submarine and drop it in the mud of an enemy harbour, then phone the prez and tell him that it would be wise for him to start negotiations...
A multi bladed fan means higher rotational speed and better efficiency than a two or three bladed design. A big 30 inch fan will provide several hundred Watt in a stiff breeze.
Even a 12 inch fan for a light truck will provide enough power for fluerescent lighting in a little sea/lakeside cabin. A fan for a Dodge Dakota costs about $110 and will make a nice battery charger.

Finally, that nursery rhyme makes sense. I always wondered why the poor weasel has to go 'pop'. The cruel bastards...

0.3W to 0.75W per fan, depending on speed. Negligible - almost nothing.

Hmm, it *is* possible to lock a WinXP Pro machine to the point that malware won't install itself, but it is damn difficult to do so. Here is a link:h /windowsserver2003/ccc/default.mspx

That will make it a little easier to convince people to install Linux systems.
So, does the Wayback machine keep exploits forever?
You mean 'Windows' and 'Word'?
Linux is still in need of one.

The Debian developers are lazy and FOS. Moz caught them out and now the Debian devs are all surly and in a huff about it. Figures.

Yup, that should fly really well past all the privacy laws, antivirus and antispyware programs.

Well obviouslyu those bursts were alian nuclear tests from billions of years ago... ;)
