Well, there is the option of having two networks; one for NFS booting, the other for inter-machine communication. Of course, this isn't really relevant for this question as it's about using existing systems in a Uni. However, for a planned system, it might well be a viable option, but a 1000 node cluster booting at the same time might be, ah, problematic!:)
Yup, there are very unsafe, especially for any small mammal who thinks hiding between the lights will save it. They ain't called "hedgehog killers" for nothing...
I actually wrote my own stuff for this while I was working at a Uni. Quotas were held in a PostgreSQL database (which means you don't have to worry about file locks etc) and I used ghostscript to do page counts of everything which was printed (there's some stuff on this on the web; basically you add a few lines of postscript to the end of the job which prints out the number of pages in the PS/PCL doc). Text documents were kludged to be #pages=lines/80 (or something)
It worked pretty well, apart from some issues with certain printer drivers where my scripts didn't pick up the fact it was postscript so it counted the number of lines/80! For graphics, this gave some very skewed results, but that was fixed easily enough. Wish I'd kept the scripts; they took me a while to write...

I rise to the bait... I can't think of any case in recent history where a British football fan has murdered another fan in the stadium. In fact, the most recent case I can remember about a football fan being murdered was the Leeds fan killed in Turkey when they were playing against Galataseray(sp?).
As for the elderly citizens being left forgotten, you should see the furore at the moment where one woman's case has been hijacked as a political pawn by the main parties. Bloody politicians...
Well, I have to agree that Icewind Dale was highly linear; do that dungeon, go to base, go to another dungeon... etc...
Baldur's Gate I was much better, and BGII follows that vein with various side adventures and other stuff. BGII adds to this with some of the side adventures being class dependant (e.g. my fighter/mage had to take on some apprentices). I dunno how Neverwinter Nights will turn out, but it should be interesting. I know of someone who played BG online and thoroughly enjoyed it.
You could argue that since it doesn't happen on intel systems it is an Athlon bug...
Basically, it seems that someone figured that the GART shouldn't worry about the CPU potentially caching 4MB pages and simplified their circuits accordingly. Unfortunately, they forgot to tell OS developers (NB: I wonder if this affects other OSs like the now doomed Solaris/x86 or *BSD?) causing these problems.
Yup, PIV's are memory bandwidth hungry (which is why I cringe when I see P4s with SDRAM). Fact is, this 'economy' decision is what drives consumer PCs; the average sensible consumer should accept the lower clock speeds of the Athlon (even if he sees behind the marketing numbers) if he saves a few hundred bucks.
If RDRAM can get its prices down to closer to DDR, it might actually compete properly. Until then, AMDs lower prices and the lower price of DDR ram is going to wipe Intel's ass on value for money.
We've seen sustained throughput of around 65% on gigabit and fast ethernet systems (i.e. 8MB/sec on 100Mbit, 80MB/sec on gig ethernet, and that's without jumbo frames which should increase the throughput of gigabit even more.
And no, this is not some fancy test lab, but a real network with various switches etc in the way.
It's fairly standard, like it or not! It also throws a fair bit of data around, which should give an indication of performance. In any case, it's probably what most desktop users are concerned with!
The DB reindex is a good test of paging as well, however.
Could well be possible; AFAIK, SETI throws around a fair bit of data, so it might do some paging. If it 'invariably' killed your machine, it should be easy to test using the boot options.
That's a rather naive assumption; it assumes that a 4KB page takes the same amount of time to move as a 4MB page. Admittedly, there will be 1024 times as much loop activity in order to move 4MB, but that probably isn't the real bottleneck, which would be memory/disk bandwidth. Also, you may gain some efficiency if you only want to move say 512KB.
In short, you're better off with 4MB pages if it's stable, but I don't know by how much. I guess some benchmarks would be easy enough to do; e.g. run Q3A with and without the mem= options.
I'd also like to know if I'm affected or not; I've been getting some hangs on starting X (the system locks up with the NVidia logo on screen) and I'd like to know if this is related...
Ah, the good old ST vs Amiga wars of olde; they followed on quite handily from the Speccy vs C64 vs Amstrad wars. Technically, both were quite similar in abilities, but the Amiga blitter chip held the edge for sprite work and IIRC it had more colours. STs still hold a niche in their builtin MIDI capabilities and I believe some are still in use in various places. Hey, they're good enough, so why replace them? You don't need a 2.2 GHz PIV to send some (fairly basic) signals to a keyboard (contrary to what Intel might have you believe; come on, how is a faster CPU gonna speed up your internet connection?????).
As for NZS, ah, good game; can't remember the music for it, unfortunately, but my favourite music was always Monty on the Run on the C64.
Hrm, they mention the C64, but completely miss out the humble Speccy and Amstrad C64. Worse still, they omit the Amiga and ST as well.
Still, it's interesting to see how many of these companies start out; Nintendo started out selling playing cards, moved to computer games and then went back to cards with Pokemon (gotta buy 'em all!).
My particular favourite line was regarding "Death Race 2000": "Public outcry against video game violence gains national attention". This in 1976...
The problem with X11 is, in part, the separation of client/server; this causes extra latency and a heap of context switches. It probably also has a lot of extra cruft that a new drawing model could avoid.
As everyone says, though, trying to get away from X11 is very difficult as practically every GUI application on linux/Unix uses X11, so it's got a lot of momentum.
It's probably a good idea to run your 'hacked' linux under a virtual system such as VMware or user mode linux; that way you can do quick reboots without losing your MP3 player, email client, web browser, IDE (VIM+gcc, right?).
It also means that when you screw things up (if you don't, I'd be surprised; I bet even Alan Cox screws up now and again), you won't lose anything. And don't give me anything about ext3; if you screw up enough in the wrong place, your filesystem is hosed.
Of course, the problem with overclocking something like a speccy or C64 is that you're likely to speed up the gameplay of anything you're running! These systems didn't have the same kind of clock as modern PCs so timing was handled by running NOPs (or whatever). Instead of increased frame rates (or possibly as well as), you have a game running twice the speed! Sometimes you might want that, but you probably don't.
As an aside, I bought a game ages ago that must have been written for a 386/486 and ran it on my P233 (as it was at the time). The game was unplayable because of the speed. I dread to think how it would run on my Athlon 1800+XP... *shudder*
Don't diss Graffiti. I've had a go with it and found it much easier to work with than the handwriting software on Pocket PC 2000 (both the builtin stuff and the version on the additional CD I've got).
It wasn't meant seriously; I posted that as a tongue in cheek comment:)
FWIW, I work in a large oil company (it's not hard to find out which if you want to search) where we work with a range of things, although my area is Unix (with a bit of Oracle thrown in). I read Slashdot regularly and even post now and again, despite linux being rare in our company (apart from a 1024 node cluster doing seismic processing).
Ah, that's the point; you're asking about "business people", not "nerds" or "geeks". You need to aim things at the intellectual level that believes that ripping off suppliers of their intellectual property/copyright is OK and anyone who attempts to enforce IP/copyright/trademarks is eeeevil...
Now to see how long it takes to get moderated down as "troll" or "flamebait" - since I have full karma, I don't care.
Here in the UK we have several providers of ADSL, quite happily competing. In fact, I get my ADSL connection from a comparitively small firm, Nildram. This is despite the incumbent telco monopoly of BT doing its best to screw it up and Oftel largely being a wet fish.
Availability is less than stellar, but it's getting better.
NB: UK users should check ADSLGuide for info on ADSL in the UK.

Yup, saw that one. My friend summed it up in 4 words: "Less sex, more fighting!"

It has relatively high latency, but it has much higher bandwidth which is what the PIV wants.

That seems to be Ali specific; my mboard is an Asus (and so it the GF3, FWIW). However, thanks for the pointer, I'll give it a try.

There's also the maxim that companies keep writing more foolproof software, but the world keeps building better fools.
