Also, many people don't seem to realise that Intel has many advantages over AMD a few that spring to mind are:
And good thing that they don't. As most of those "advantages" seem to be in your imagination.
Less power consumption (which makes a large difference over 20,000 desktops and 1000 multiprocessor servers)
Indeed, with 20k processors, this makes 452kW (avg), 614kW (max) difference. To AMD's advantage, that is.
Self shutdown - if the heatsink falls off an Intel processor, it throttles itself down until it stops, if required, so that it doesn't burn, whereas an AMD chip just burns.
New Athlon systems do shut themselves down if overheating.
Less heat - this is a major issue in a datacenter
Production of heat is directly proportional to power consumption, so AMD wins here as well.
Descent cache levels - 2Mb in the current Forster chip set Xeons.
AMD does not have any chips with huge cache, true, and it may lose some of the server market due to this, but on desktop machines, nobody uses these.
Nothing. Except maybe stop whining, but then, go ahead and whine if you want. Not that it's going to help.
If you are as you claim, and download few movies and some software now and then, you shouln't be anywhere near the 30GB/Month limit so this doesn't even affect you.
Indeed you get what you pay for, and if you wish to get guaranteed three hundred gigs a month on 1Mb line, then you pay for it and you pay LOT MORE than you are paying now.

Plain old text is not plain text. FAQ claims the following:
HTML Formatted: You determine the formatting, using allowed HTML tags and entities.
Plain Old Text: Same as "HTML Formatted", except that
is automatically inserted for newlines, and other whitespace is converted to non-breaking spaces in a more-or-less intelligent way.
Extrans: Same as "Plain Old Text", except that & and are converted to entities (no HTML markup allowed).
Code: Same as "Extrans", but a monospace font is used, and a best attempt is made at performing proper indentation.
So it seems that "Extrans" (whatever that is supposed to mean) would have done the job...
When they say there is no GUI they DON'T mean there is no _shell_ (explorer.exe), but that there is no graphic environment at all. Explorer needs that to run, and so does XFree for windows.
If you'd have WinNT license (which you would need to legally use a part of windows, maybe not even then if EULA prohibits taking something out and using it "stand-alone"), then why not run that windows instead?
I would rather wait untill technology advances farther and then...
Technology doesn't advance by itself.
Nor does the existing technology (and we have technology enough to do anything you mentioned) become any cheaper if there is nobody to use it while it is still expensive, and refine and test it enough for someone with less resources to use.
You are still spewing out your mass-produced junk probes hundred years from now if you are not willing to shell out some cash for more ambitious goals. No way around that.
Even though there are, what, at least 10000% more accidents involving standard airplanes than space vehicles. After all, space flight is rocket science.:)
I wouldn't be so sure about that percentage. At least if you put it into the perspective. Sure, there have been lot more plane crashes than fatal orbiter problems, but there are helluva lot more planes as well. If we have (these numbers are invented) 1000 aircraft and 10 of them crash and 100 rockets/shuttles/whatever and 2 of them blow, then planes are 50% safer.. there's just lot more of them so accidents still happen more often.
Rocket science or not. I'm not dissing the space progress, but I'd be willing to claim its safer to fly on a plane than on a Shuttle, they don't need to worry about heat shields or rocket engines failing.

Hey, what can you expect? Slashcode is written in perl.
As for sentient unmanned aircraft...well, at that point I think I'd be more worried about losing control of the world entirely rather than a few random bombings. Once sentient computers are possible it is pretty reasonable to assume humanity's trek is effectively over. (whether or not humans go on living, they won't be relevant)
Sentience of a hypothetical electric computer would be so vastly different from that of carbon based life forms (that would be humans) that I don't see why one would immediately make the other totally irrelevant, they could very well complement each other.
Well, only time will tell whether the bad scifi flics (and you) have it right.
I think Morrowind got the "engine" right, so to speak, in making it first person, the character traits, advancement, alchemy, etc.
I don't much like first person engines, NWN apporoach wins here - but that's a matter of taste, and as we are talking about 3D engines here, it shouldn't bee too hard to have one that has both decent 3rd and 1st person modes.
Skill/advancement system of morrowind is wonderful, even if in some aspects foo easily exploited (it's a bit - okay, no, helluva boring to for example to buy some herbs and mix 'em into potions, sell, repeat and in no time, you've got your alchemy skill at 100%, not to mention a shitload of money).
And it is extensible too, haven't really looked very deeply into the devkits of either, but both of those games have them, and both are good.
What it most misses is multiplayer, preferably as MMORPG as the world is huge. The guild system for example is nice, each guild has lots of subquests for advancing etc, but think how really great it would be if those giving you tasks would be other people (higher in rank than you) playing, and the quests something more dynamic instead of only predefined scripts (whether they are created by Bethesda or someone with editor). NWN DM client and mp cababilities COULD probably accomplish something like that... yes, combination of those two games would really rock.
Fast forwarding IS editing just as much as filtering is. Other is skipping parts of the movie by hand, and the other does it automagically.
Both are editing, and both are your goddamnit own decision and unless you are somehow redistributing your edited film, nobody should have ANYTHING to say about it.
All that is dependent on how you view it. The clone may not be constructed of the same particles original was (but then, neither is the original after some time), but it has exactly the same memories, and consciousness, if it is indistinguishable from the original, then by all means it IS the original. It remembers stepping into the teleport booth as you, and it remembers stepping out of it as you. Like a digital copy, neither of the copies is any more "real" than the other, and it's not possible to know which is original.
Of course if you believe there is something more to being "real you" than energy and matter patterns in our brains, like "soul" somewhere that goes into heaven or hell as your original body is destroyed, then the copy won't be you.
Some radio stations still use them today, [denon.com] that is, ones that haven't totally moved their music collection onto computer.
They are also used in DVD-RAM disks... dunno whether anyone uses those anymore, now that DVD(+-)R(W) has surfaced.

It's a very GOOD advice in general, always! That is, assuming you go and get your brains from wherever they are, and think for yourself. Advice is just that, an advice, and can and must be adjusted to suit the circumstances.
Nothing in the comment "it would be nice if you would bother to patch the machines" forces you to blindly assume that it says you need to apply any patch nanosecond after it rolls from Microsoft, or if there are known problems with it.
Go ahead, do your QA, and apply the patch after that. If it was patched six months ago, there is no excuse to not have done that QA by now, if it was only recently as some say, then it may very well be acceptable to still be testing it, but that doesn't negate the fact that generally having patches installed is and will always be a good practice.
He didn't deny that it FLIES, but was skeptical about the other promised things.
Short, tethered test flights on very low altitude tell nothing about either of those.

As it is, we have no firewall, and our SQL server is open to the net because the web server has to be. Oh, and obviously we don't have a VPN running because that would be too expensive.
And what prevents you from running for example an iptables or an equivalent for whatever OS you are using on that same machine and only allow inbound traffic into tcp 80, if you really can't afford any external firewall box?
What about order entry for Lands' End and Amazon? Those are all database queries. Dear God, I hope they're not using MS SQL for that.
Database queries, yes.
Database servers on public Internet? NO!
Those DB servers of amazon etc are in their private intranet, and only their web servers can access them - your browser does NOT do any sql queries directly, the web frontend is responsible for that.
how about if there is a worm without a fucking patch? and how about if the patch just came out? you blindly patch servers without a QA process? sounds like msce advice to me.

Why would someone need to know how to compile software? Assuming our fictional newbie is using a popular distro and knows someone who knows things, he can get a precompiled and packaged version from eg. freshrpms, and I'd be guessing there is equivalent for debian and mandrake as well.
figure out the appropriate command-line options, etc.
Which would be... exactly what? Mostly, command-line options are not needed except for finetuning that our fictional dumbass does not need or want to do anyway. "mplayer filename" is enough.
As for the GUI, I also wouldn't recommend it, for most of the reasons noted in Jamie's rant.
Once you've got movie running, you don't need any stupid GUI to eat screenspace, and basic keyboard navigation takes six or four keys: arrows, F, and space.
Anyone can memorize that, especially as they are very logical choices for what they do.
Tried to walk a semi-linux-literate person through it, and he still has no working MPlayer.
No doubt he doesn't if you forced him to try to compile it himself and use the GUI version.
I don't now why, or when the trend has started (maybe it's reading, left from right...), but direction "right" is generally associated as more, or forward, and "left" as backwards.
So light and left arrows as fast forward buttons do make perfect sense, they are intuitive and logical.
Space is pause in LOTS of video players, whether they are on linux and not, so copying it is also perfectly logical, since it's the first place someone that has used any video player at all will search. Not only that, but it's biggest key and easy to find and press quickly. F stands for fullscreen, but maybe the fucktard can't spell.
What exactly DO you find to be not logical and unintuitive in those "assorted keyboard commands", all four of them?
Worst of all, the troll is (or so it seems, I've never heard of "JWZ" before) emacs freak, and HE has guts to comply about few simple keyboard commands? Did he forget to take his medicines or something?
How is it economical to speed-bin a chip and connect it to slower ram on an expensive PCB, just to prop-up the prices of the highend part?
It IS economical because manufacturing costs may well be bit higher now, but R&D costs are what pays most in these things, and they are effectively HALVED by designing only one board.
In addition, it's latest and finest out there, and it's a goddamnit luxury item. ATI can charge whatever they want for it and its price has nothing to do with manufacturing cost of itself, or it's lower end brethren. More with those aforementioned RD costs. High-end items always have their prices sky-high, they are not meant for average user. That's how capitalism works, if that doesn't fit you, tough.
I was just refering to the hardware method in my post. The software method, while easier, is also a risk. Well, the hardware method is DOUBLE risk, if that's how you put it. First you risk totally screwing it up physically, and after that, you risk exactly the same as with software.
The software method attempts to push the card beyond its factor tested limits. Most of the chips on the 9500's probably can remain stable at 9700 speeds but you're in danger of frying your memory, as stated above. It doesn't force neither core nor memory to 9700 speeds, it only enables the extra pipelines, after that, you can overclock as far as you deem it safe.
And usually, unless the user is most stupid person on the whole world, overclocking is no risk - those things tend to be very unstable and have image artifacts everyone can clearly see well before any damage can occur, if you don't understand that and turn the speed lower again and something goes wrong... well, there's a price to pay for stupidity.
