If you are looking for a huge webserver or FTP server or such, then maybe a Content-addresable switch is the thing for you, and you really don't NEED a "beowulf" cluster to achieve your goal.
I recently set up a "web farm" of 10 Linux boxes, using off the shelf Compaq DL580 servers (running SuSE linux, pretty much straight out of the box). The magic component that made it a "cluster" was the Content-addressable switch which sent incoming web traffic in a load-balanced fashion to the 10 stock web servers.
Finally, the serial consoles of all 10 were run to a terminal server hooked to a stock DL360 running Red Hat for access to the consoles of the 10 servers, if necessary.
I can have that up for you in 3 days from receipt of the hardware:)
What the "nodes" consist of - the article wasn't very specific - two multi-processor PC's per rack cabinet - sounds a lot like the RS-6000 based "nodes" that ASCI White uses. Those are two per rack cabinet, each with 8 CPU's and a shared memory structure - sounds similar.
As for 1000 years of weather prediction, fine, but can it accurately predict the weather TOMORROW is what I want to know:)
I noticed with interest that Cat Stevens' Morning Has Broken is on the list - I can't see any jet/building/bomb/terror/death references in it at all...
Your wish is their command... The Market-roids are already lining up an onslaught of the Battlebots R/C action figures and happy-meal inserts as we speak. I saw tonight's Battlebots and they are selling the crap already. One semi-cool thing, though, the builders of the bots they are modelled after supposedly get some cut from the profits. Hmm...
They tried something like what you are suggesting. Instead of interesting it proved to be, as the English say, "a crashing bore". The truly autonomous robots had to take the time to map the arena area, and search around for the other bots hit-or-miss. Each match took MANY hours to complete, most a draw. Yawn!

Did you read the WHOLE article? Non-mobile Duron prices are discussed at the END.
A PDP-8 can't run Unix - or even C-based re-entrant programming, because it has (had?) no Stack Pointer! You needed at least a PDP-11 to run Unix. A 286 could (and DID) run Unix - remember Xenix?
Brings to mind, in a former life, I was co-author of a public domain program, and also found the FSF/GNU to be too restrictive. The program was a composite of snippets of public domain code from wherever, and there was no way to sort out who wrote what parts, what was PD and what was original, etc. So, we had to say "NO" to to RMS himself. That was a drag! - I like and respect RMS and to have our program asked to become GNU was quite a compliment, but ah, well "the devil's in the details..."
The GNU versions of utilities, as was mentioned, have now become a superset of the original utilities that they replaced - who would give up bash for funky 'ole sh (even ksh?)?? It is a symbolic victory, nothing more. The richness of driver support for the Linux Kernel is another example - the hardware support for SCO/SysV pales in comparison.
I personally owe a big Thank-You to IBM for publishing the BIOS standard and the assoicated "Blue Book" (PC Hardware Technical Reference). Those two books enabled me to understand PC hardware and the underlying reasons (the BIOS) why stuff actually did what it did. The knowedge gained by reading those texts enabled me to have a successful career reparing PC's down to COMPONENT level (ancient by today's standards - but then a Floppy drive cost $450.00, you HAD to repair them, not just throw em away). Of course, in later years and lives, I graduated on to software and programming, but the Assembly language knowledge in the Purple book still is a foundation for most of the systems and low-level programming that I do today. Now that IBM is embracing Linux and its community, more the better!! Thanks, IBM!
It didn't sound like it was the paint. It sounded like the metal was an amalgam of magnesium and some other cheaper (and non-flammable) metal, probably 'pot' casting metal. That's why it took so much more heat to get it started.
Oh, sorry, I see you had your sense of humor surgically removed. I shall refrain from further uses of humor since your damaged brain cannot distringush it from normal conversation.
You're thinking backwards. No resistance means VERY LOW not VERY HIGH. The LOWER the resistance the HIGHER the current flow. If you put a large (say 1 Meg Ohm) resistor across a suppy you get very low current flow. If you put a very small (under 1 ohm, like a superconductor, say) resistance across the same voltage you get LOTS of current flow and since the superconductor is the load that's where all that energy goes. Blammo!
Actually, a Xenon strobe or Arc discharge lamp when firing creates a plasma arc that has an approximate effective resistance of about 1 ohm. Trust me on this one, I used to design strobe lights for a living. 500 Jolts into 1 ohm develops a current of 500 amps according to Mr. Ohm. Waaaay less than 10 KA...
If you read the first couple of posts, a software based keylogger would be problematic because of multiple O/S's - are you (the FBI) going to install one per boot partition? Plus, the other problem is they would be pretty easy to detect to a computer user with half a brain:
.
Snippet of "New" CONFIG.SYS:
.
blah;
DEVICE=C:\FBI.SYS
blah;
.
.
assuming DOS... Which most anti-virus software would choke on... No, it's gotta be a hardware logger, or radio transponder in the keyboard/CPU.
No doubt, They went out to Best Buy and got a duplicate, embedded the bug, then painted it with fake Chee-to's (TM) orange dust, Pizza Sauce and Jolt Cola (TM) stains, and surreptitiously replaced it with the original - Didn't anybody see The Soprano's Lamp Episode?
If you read into the test parameters, 10^4 A - (that's 10,000 AMPS folks!) If you pump that much current into any superconductor, for the brief moment before it vaporizes, it will radiate all up and down the spectrum from DC to Cosmic Rays, and will probably emit some freq's we havent discovered (observed) yet, including ones that act like gravity(ons). That's more or less what the Star Wars (Reagan's, not Lucas's!) X-Ray pulse laser was all about (but it used a nuke for an energy pulse instead of 10KA).
A company I worked for in a former life made Video Inspection systems for the printing industry. I was a design engineer there, and they decided one day to fire my boss (and friend), the Director of Engineering there. The new director was a smug bastard and he and I didn't see eye-to-eye, so, eventually, he had me fired. Talking to a former co-worker about 6 months later, I heard that the wonderful new hardware system that this new director had designed to replace all the stuff I had designed DIDN'T WORK! The new director couldn't fix some major bug in his new system, and he B.S.'ed the owner of the company that all was well right up to the morning of a MAJOR industry trade show. From what I heard he was fired on the spot! Sometimes the karmic wheel turns slowly...

Gist: Isn't it a federal crime to screw with the data on someone's computer without the owner's permission? This seems tantamount to a virus or trojan altering web content recieved locally, without the owner's knowledge or permission. This might be nullified by the tiny 6-point shyster type in their "license" agreement verbiage, however, if you "agree" to let them screw with your stuff. If not, we may have an solution.
Solution: Have the authors/producers arrested and drawn and quartered, per the new anti-hacker laws.
We'll have toys fighting toys - He who dies with the most wins! So we have unmanned tanks being shot at by unmanned AV's, being shot at by automated SAM sites, which is fine, until someone runs out of toys. Then a human shoots back at the UAV, and then what?? Right back into conventional war as soon as the toys are gone. Better living through technology. But there's always the possibility that war breaks out and no one shows up...
I was in the video industry back in its heyday, and worked for several game manufacturers in the Chicago area. Taito had designed in an RS-232 port on their 'American' system (Qix, Zookeper, Space Dungeon, Kram, Electric Yo-Yo). Damn shame they never wrote firmware to use the port, though. Supposedly they had plans to up/download accounting info, diagnostics, even new game code via that port. Also they discussed using them for back-to-back game connectivity (2 player, 2 cabinet games) like some of the new driving games that are interconnected. This unfulfilled vision was back in 1983. Funny thought:
