The reason why I suggested ethylene glycol alone in a liquid cooling system is that it's non-conductive with a more than passable heat capacity. Mixing in water brings back the risk of conductivity (any impurities of an ionic nature and it's conductive...)- while it'd work better than water alone or antifreeze alone, it's not what you're striving for with antifreeze alone.
I know that. However, it's NOT conductive (Like with all cases of water except high-purity distilled...) and while it's not as effective as water, it's still more effective than convective cooling (because air has a lousy specific heat capacity even compared to ethylene glycol)- it'd work fine. I'd not take chances with a leak and water...
Alcohol wouldn't be exposed to fire and stuff inside your computer (unless you've got worse problems...:-)
i.e. a refrigerator- that's extreme and a commercial company does the same thing (Kryotech). That is not the same thing as a phase change heat pipe and radiator (The device referred to in the article)- it's moving the heat, but it can't get the chip below ambient.
They're using heat pipe technology to move the stuff about- that doesn't mean water. Furthermore, radiators do NOT mean water is involved- alcohol or ethylene glycol work rather well in radiator applications (which is why I keep wondering what these people are thinking when they run liquid cooling systems with water.
This whole mess was due to his lack of a careful reading of the boilerplate. It was loosely set up so that the interpretation that CRC's legal team came up with (Which was that MathWorld was infringing on thier copyright). They kept asking for money, using a lawsuit as leverage, according to the blow-by-blow account on MathWorld- this isn't about infringement, this is about cash, pure and simple. In the end, Wolfram caved because it was cheaper to give the cheating SOB's what they were asking for than to fight for the principle of the thing.
If my job doesn't depend on something from CRC Publishing, I'm NOT buying it anymore.
Try an iPaq running Linux/*BSD and an 802.11 card- if they can afford a laptop, they probably can afford the slightly cheaper and even less obtrusive palmtop computer.
Almost all modern apps require hacks like MMX and 3DNow? (Realize that while you're using either of those, you can't use the floating point pipeline because it uses some of the same paths as the SIMD engine. Also note that it costs cycles to switch back and forth and if you're not doing LOTS of matrix math, you're not going to use them- you're going to use hand tuned floating point/integer code.) How many really, really use them? Not a lot of them, in reality.
x86 has hacks to get SIMD instructions, limited register spaces, weaker floating point, etc. AltiVec is a more rational scheme and PPC CPUs have much more useful register sets and rational instruction sets, and it's floating point is nearly twice as fast.
Hacks do not a "Porche" make. To use your analogy completely, the x86 is a Mustang GT to the PPC's Porche. Both will get you there. Both go fast- but one is higher performance and handles better.

Isn't used to paying for software? Riight. If it's worth something, I buy it or pay for support from the people providing it. I don't use what I don't pay for or get legitimately through other channels (freebies from companies, beta copies, open source, etc.)- most of the Linux crowd is the same way, what makes you think we'd use pirated copies of things?
The reason for the problem with Loki's multifaceted- there's the delay, there's the fact that a majority of the Linux crowd's impatient (yes, that's the word for it) and has the luxury of dual booting (unlike the MacOS crowd...), the relative dearth of driver support for 3D cards until recently, and how expensive it is to license AAA titles (I personally think they bit off more than they could safely chew in a year's time...).
Doesn't matter where they have/don't have a monopoly- if they're using thier monopoly position or resources to move into other markets, it's going to be covered by the setllement. They're using their monopoly status to work their way into the console market (Don't for a second believe that they're not- if they weren't leveraging Win32 to get there, they'd not even be a considered system option...) so it's probably going to be considered part of the whole shebang.
The clue is the MB1030 Ver 2.0A on the motherboard. (BTW, My current employer is responsible for the design and software that was on those- it's QNX based for that model, subsequent models used our own homegrown Linux distribution...)
I've got 5 of these things sitting on the floor of my office right now. There's more elsewhere in the space- it's my understanding we're planning a fire sale on these and a few other things on EBay shortly.
1) It's not as simple as plugging a HD in, despite the availability of an IDE header- the box can only accomodate a laptop HD at best. It also needs a special cable to adapt the 40 pin to the 44 pin on the HD (and you DON'T have a standard power header for the standard interface either...)
2) He used a Disk-On-Chip instead of an HD.
3) $299 gets you a box with a Fansink and a nifty space heater with a moving HD and NO TV interface- or you spend $299 on an embedded system with no moving parts whatsoever and a TV interface built into the box.
4) It could be argued that this could be a hack as there's at least a few of these boxes floating about that were shipped as set-top boxes (I know, my employer used to sell the boxes, rebranding them for people like NetFrontier, etc.)
The Allwell 1030n is a National Semiconductor Geode based machine, not the Celeron that he claimed he bought.
Go to the Allwell website and look up the STB1030N from the products pulldown. Right now, they're selling these things for "router appliances" and really cheapo set-top boxes. In the router appliance arena, they're not too bad; in the set top box arena, they're weak (though usable for many things.).
I did, however, say that some things didn't need network transparency or the indirection caused by all the trips to the server and back. Doesn't matter if it's unix domain sockets or network sockets (which is picking nits, BTW)- it's still indirection and a lot of it that things like SHM doesn't fix (If it did, why do we have things like V4L support and DGA in XFree86?).
Any time you're using any sort of RPC mechanism, you're adding some sort of indirection (and if SHM was so great, why are people using DGA with things like xawtv?)
Network transparency for a tuner card, DVD player, many video games, etc. is verging on irrelevant- you're wasting loads of energy and efficiency for something that will, under almost all cases, never ever be used in that manner (I challenge you to play Quake 3 via remote- you'll not be doing very well...). For those things, peak performance is what matters.
You've got a server machine with all those shared libs, right? Does an X terminal need those shared libs locally on itself to operate or can you get things like KDE to run on the X terminal session? No? If it's a "no", those shared libs are an application interface to X to make it easier to use its protocol accordingly.
Another experiment for you...
Take those shared libs and the apps that use them. Rip out the XFree86 server and replace it with a GGI or the XDirectFB server. So long as your apps don't use DGA or SHM (and maybe even then...) your apps will still work largely the same- why? Because, X, at its heart, is a protocol not shared libraries, etc. It has to be for it to all work transparently over a network with so many differing GUI rendering targets.

They seem to largely take a beating and keep on ticking. When the PS2 pre-rollout occured, they had nearly all the kiosks working with no hitches. What's going on with the XBox is not going to fly with most of the market- no matter what people think otherwise.
If it's hanging/BSODing now, do you REALLY think anyone's going to buy off on it? (At least the demo units for the PS2 work well...) Yes, those are neato games, but there's always other companies out there willing to fill that void MS is making right now.
Pot's largely harmless if you know it's pharmacology.
Cocaine is damn dangerous as are all the opiates.
Many of the halucinogens are dangerous as well.
All the deleriants (e.g. scopalamine) are very dangerous.
Dangerous in the sense of serious bodily harm in the form of easy overdose, injury to oneself because you're very definitely not in control of yourself, etc.
I don't agree with all the thinking they have, but some things are beyond ill-advised.
Look in any truck stop. You'll find pirated tapes and CD's in a Lossless format for sale.
All it takes for it to happen online is someone to use shorten and a fat pipe to allow downloading/uploading. MP3's, WMA's, TVQ's, and Ogg's merely make it easier with the need for a fat pipe lessened.
They're on the brink of obsolecence right now- bandwidth is high enough to make it a real problem for them, they're pissing off the artists left and right, and they're beginning to see the pissing off of the consumers themselves.
I just wish they'd die or adapt quickly- all this tar-pit thrashing about they're doing right now is going to make things ugly for everyone, including themselves.
However, I think we're on our guard and there's going to be many watching out for that one- this was being ran in stealth mode for a while before we caught wind of it. Hell, Hollings isn't talking to anyone about it other than the backers of the proposed bill.
