As with any PC hardware which implements ACPI (basically every modern system), you use the "power button override." See ACPI v. 3.0b section 4.7.2.3 "Sleeping/Wake Control. The description of the PM1.PWRBTN_STS bit in Table 4-11 gives further details.
In short: press and hold the power button for 4 seconds, and the system will transition straight to the G2/S5 Soft Off state.
This is a tautology. Introducing concepts that are beyond what can be scientifically experienced is useless from a scientific POV, like e.g. the concept of color is useless from the point of view of counting from one to ten.
On the other hand, the concept of color is absolutely critical from the point of view of counting from one to tan.
No, my point was they didn't have to add more signals to increase the speed of ethernet
Ummmm, yes they did. There were two pairs used for 100BaseTX, a transmit pair and a receive pair. This left two pairs left over in a standard ethernet cable. For 1000BaseTX, the two extra pairs are used, and all the pairs are still clocked at the same 125MHz as fast ethernet. The tricks are that they use a more efficient encoding on the wire (giving two bits per symbol per pair), and, more importantly, that they simultaneously transmit and receive on the same pairs of wires, giving full duplex communication at 1 GBps clocked at 125MHz.
Anyway, my nit-picky point was that they did have to add signals to make gig-E work, in addition to using a set of crazy electrical tricks to make it work. I don't think it's fair to imply that Ethernet has near-infinite scalability over copper, or that any other serial protocol will scale infinitely either.
The thing you're missing is that in a modern system with cacheing, single-byte writes to RAM almost never happen. The CPU/cache system gathers all writes in its caches, and only writes out data from the caches when it either needs to make room in the cache for other data or is explicitly told to do so by the operating system.
Since all writes are from the cache, all the writes to memory are of cachelines (usually 16 or 32 bytes), so the memory subsystem just does a write, not a read-modify-write.
I agree that it's a pretty sweet setup, but I don't think he uses it quite so much anymore. Which is probably a good thing, since in his (relatively) new place, his living room is so small that the laptop is about as far away from the couch as the CD changer is.
I've been toying with the idea of calling the BSA about this, just to see the look on their faces when - after a long time - I finally tell them the company I work at is Microsoft:-)
I have been considering ICP Vortex RZ and RS series and AMI Megaraid as possibles, along with the Mylex line of controllers. I would like some opinions, praises and even nightmare stories on any of these.
The parent post would seem to be an opinion, and perhaps even a nightmare story, about the Mylex line of controllers. Way to read, read-boy.

On what do you base your opinion? In my opinion, the universe will end in a brilliant light show, and intelligent beings from other worlds will build a temporally isolated space restaurant to watch the show nightly. But, as noted, this is just my opinion.
Are you sure about that? AC watts are usually measured as RMS power, whereas for AC volt-amps are peak (which for sinusoidal AC is a factor of square-root 2 larger than RMS). In DC, volt-amps and watts are equivalent.
950 Watts x 1.414 = 1340 AC VA
180 Watts x 1.414 = 255 AC VA
1400 VA -> 1340 VA is 4% loss
280 VA -> 255 VA is 9% loss
There are still losses, but I don't think they're as bad as you're saying.
As far as I can see, the encryption issue is just a red herring. Sure, the calls are encrypted on the air, but that's just to prevent casual eavesdropping with a radio receiver.
Vodaphone HAS to be able to decrypt the calls, since the calls may ultimately go out on the POTS network. The issue doesn't seem to be that the wireless network is encrypted, but that there isn't infrastructure in place in the wired base stations of the network for call interception.
Actually, from what I understand, a better analogy would be that NT is to VMS as MS-DOS is to CP/M. IIRC Microsoft hired one of the chief architects of VMS to design NT, so NT was originally fairly similary to VMS. And many, many people have noted that DOS was kind of a hack that MS whipped up to keep IBM from going with CP/M.
Well, maybe this isn't the best analogy either. D'Oh. Maybe next time I should try to support my claims with facts... nah, too much work.

Yeah, I mean how could you possibly fly when something like nerves are involved. Up 'til now, pilots have sat limp and motionless in their chairs.
If the nerves in your arm twitch every time you fart, you're probably gonna have trouble flying a plane with a stick as well.
