Which million are you talking about? If you mean a US million (1E6) then that isn't so much money and if things got bad enough i'm sure the 1 1/4 million you mention could be raised. But if you mean the other million (1E9), then that is indeed a large sum of money that would be difficult to come by.

Uh... not quite. It takes about 2,000 volts per centimeter of air that you want the current to flow through. I have a 15,000 volt transformer and it can create arcs around 3 inches or 7 1/2 centimeters. To get 20 meters you'd need about 4 million volts. (20m * 2000 V/cm = 4E6 V)
I'm in a similar situation at the library where i work. All the staff here except me run variants of Windows on their desktops. I installed a program called taskzip (do a google search to find it) on the clients and scheduled it to run at 02:00 when no one is around. Taskzip connects to a file server (running Samba) and creates a zip file of all the user's important files. Several people are running Windows 2000 which makes it really easy to configure taskzip since all their files are in "\Documents and Settings". I think taskzip is freeware. It works well for us. If your staff can't be trained to leave their computers on at night for the backup job to run, then in the BIOS set the machine to automatically boot just before the backup. If the BIOS isn't that advanced... then i'm out of ideas and someone else will have to suggest something. Perhaps set up taskzip to run on boot or shutdown or at lunch break or something.
A couple years ago i was having some pain in my wrists and the tops of my hands. I bought a cheap ergonomic keyboard and the pain went away.
At the time i bought this keyboard, there were several brands available from Comp-USA and Best Buy. All the brands looked identical; my guess is they were all produced by the same third-party manufacturer and relabeled as necessary. The one i have has no indication of a brand on it. I want another one for work but haven't been able to find one just like the one i have. Any idea what brands it might be? In hindsight i wish i would have saved the box...
While working for the hardware support office at a university i was taught how to clean keyboards. Most of the time when a keyboard is "broken" it just needs to be cleaned. Here's what you do:
Remove the casing on the keyboard. You'll probably need a Phillips type screwdriver for this. If the case is not easily removed, i don't know. You're probably SOL in that case (no pun intended). Once the case is removed, soak the keyboard in hot water for a few minutes. Swish it around a little until all visible gunk has gotten off. If pop or coffee was spilled in the keyboard, you might need to scrub it a bit. I'd suggest just using fingers to scrub it and do so gently so as not to scrape the electrical traces. Take the keyboard outside and while holding it tightly, swing it around violently to shake all the water out. If anyone happens to see you do this, you'll probably get some funny looks but they won't come too close.;) Once water has been shaken off, let the keyboard air dry before putting it back together. We always set it on top of the intake vent for the building's ventilation system, which dried out the keyboards in a couple hours. If you don't have such a thing, let them sit on a counter for a day and you should be fine. Put the case back on the keyboard and test all the keys.
If a key doesn't work, here's what you do to fix it (if it uses actual push-button switches and not the mushy pads like the cheaper keyboards do--i don't know what to do for those). Carefully pull the key off the switch. If you don't have a tool to do this, gently prying at it with a flat blade screwdriver usually works. Squirt a very small amount of WD-40 into the keyswitch. Press the key many times to work the lubricant in, and then test it. If the switch is still broken, try to find a keyboard with similar switches and transplant a switch. I always try to keep one or two spare keyboards lying around just to steal switches from. Transplanting a switch requires soldering/desoldering ability.

What are the 2.0 kernels still being developed for? I'm not trying to troll, i'm seriously curious. I run 2.4 on my workstations and 2.2 on my firewall (a system based around 2.4 isn't small enough to easily fit on a floppy). Could someone give an example of an application where a 2.0 kernel would be better than a 2.2 or a 2.4?

I know you don't want to reuse an old computer, but when faced with a similar problem that's what i did. I used a 486-133 (AMD CPU) with 16 MB RAM. I didn't have a spare case at the time, but i did have a power supply and a cardboard box. I put the motherboard and power supply in the box, which was sized so neither moves around much. I added a floppy drive, which normally is encased by an anti-static bag to keep it from shorting the motherboard (since the floppy is just laying in the case). For a graphics card i used a circa 1994 or 1995 PCI card. The CPU doesn't have a fan, and to reduce noise further i opened the power supply and removed the fan there. To keep the power supply from overheating, i left the lid off. I added 2 3Com 3C509b cards and 16 MB of RAM. I configured a floppy disk using the Coyote variant of Linux Router Project (http://www.coyotelinux.com/). Although i've set up IP masquerading and firewalling using a full-sized distribution as well as the standard Linux Router Project, Coyote makes it pretty easy so that's what i use now. I've been running the machine for over 2 years without problems. Since it is only a 486 it can't handle 100 mbit, but for a DSL line it works great. Plus i have a computer built in a cardboard box.
Why do some operating systems work under Plex86 while others do not? i.e., once you have a virtualized system why doesn't it run all operating systems right away? Do different systems use different processor instructions that haven't been handled yet?
Most PC games run under Windows. Let's just say for a moment that Windows truly is a "protected multi-tasking system" (even though in reality it crashes often enough to not be worthy of being called "protected" and the multi-tasking gets chunky if you look at it funny). How many people run other stuff while gaming? Not many. They are too busy paying attention to the game, not to some other app. Games tend to be resource pigs. So most people probably shut down whatever other apps they were running anyway. Not only that, but i've found that most Windows games make the system unstable and so you need to reboot when done anyway. So what again is the disadvantage to not booting off of a CD to run a game?
I own two high voltage sign transformers, a 15,000 V 30 mA and a 12,000 V 60 mA. Bought them used for less than $10 from a local sign company. I've used them to fry just about everything i can think of. Gummi bears are kind of neat to fry, and still taste good afterwards. When frying electronics i use a pair of high voltage wires i built with alligator clips on the ends. I clip one to the side of the device to be toasted, and wave the other over the equipment to areas that interest me. If you put an arc directly through a capicitor for long enough they sometimes explode. Most components just melt except for chips which you can draw lightning traces in.
I think the NIC was meant for school and similar environments where for security and anal retentiveness reasons you don't necessarily want people running a mail client.
I work at a library and recently we purchased a NIC for evaulation. The first thing i looked for when booting it for the first time was whether there was an e-mail client. I was glad there wasn't because if there was i would have had to rebuild the CD without the e-mail client. The powers that be who set computer usage policy want patrons to be able to use the web for research, not to spend all day chatting on e-mail. I don't quite understand this since e-mail can also be a research tool, but my opinion doesn't matter since i don't set the policies.

Hard drive space is cheap. I'd rather have to allocate a couple GB more swap than have random processes killed off in an OOM situation.
