Sorry to reply to myself, but... people like to rail on MS claiming that they don't document their interfaces - poke around MSDN a bit.

Their versions of php and apache are both incredibly old (1.3.27 or 1.3.28 is current for apache, and PHP just released 5 RC1 with 4.3.x being current) - I hope they set up apache to lie about its versions.
It is very precise on an absolute scale (as in, compared to the size of things we normally deal with, the accuracy is very high).
However, you need to operate at the bleeding edge, so the actual features themselves are VERY small - small enough that a few atoms misplaced here or there can start to have a noticeable effect. If you wanted better yields, you could use larger features, but you'd sacrifice performance.
I trust my parents not to deliberately install something stupid. It's the accidentally-clicked-yes-to-that-IE-dialog kind of problem I'm worried about.
It's not often that users like that legitimately need to install software. Change their account type from "Administrator" or "Power User" to just "User", and they'll be much safer. For when they DO need to legitimately install something, you could let them have the administrator password.
I really have to wonder about that "240kg" number. Assuming a density equal to water, that gives us 240 liters, or 63.4 US gallons. That works out to about 1.5 barrels of oil. At $37 per barrel of crude oil, we have $55.50 in the oil alone.
The article doesn't specify the type of fossil fuel, but if it is anything other than crude oil, the price goes up. Also consider that fossil fuels are less dense than water, so it's actually going to be more than 1.5 barrels.
You can get a 17" CRT for about $80 from newegg (or around $50-70 using froogle). That doesn't leave much room for anything else if you want to make any money as a manufacturer.
Why can't I get my liquid nitrogen cooled 24 Ghz ahtlon64 then? I thought we weren't capable of making gates that would switch that fast?
Your CPU has paths more than one gate long that have to switch each cycle. Even if you DID design a processor with 1 gate per pipeline stage, you'd still need more than 41ps just for the clock-to-q (time it takes the data to come out of a flip flop) and setup of the next flop (time before the clock arrives that the data needs to be valid).
x86 allows for non-executable areas of memory if you take advantage of segments. Unfortunately, lazy OS writers (both MS and the linux crowd) decided that managing segments was too difficult, and just set the code segment to encompass the whole address space, nullifying the potential advantages segments provide.

This is especially good, when you look at Pentium 4 processors with Northwood cores vs Prescott cores - at the same clock speeds, the Prescott is generally slower, but you don't see that in just the GHz.
AMD to expand, add Austin jobs Chip maker leases additional office space in Northwest Austin.

Chip maker Advanced Micro Devices Inc. has leased additional office space in Northwest Austin and plans to add more engineers there this year, a spokesman said Wednesday.
It will be the company's first expansion in several years.
AMD has leased an additional 36,000 square feet at 9500 Arboretum Blvd., which houses the company's Personal Connectivity Solutions division. The company previously had 56,000 square feet there.
The operation, which employs a few hundred people in Austin, designs low-power chips for Internet appliances, television set-top control boxes and Internet access devices.
AMD spokesman Drew Prairie said the company expects to complete construction of the new space this spring and begin phasing in new workers, with a focus on design engineers.
The company employs about 3,000 people in Austin.
CB Richard Ellis represented the landlord, Pac Trust, in the transaction.
all Xbox games must access the hardware the DirectX APIs and XTL libs, rather than writing direct to hardware registers/ports.
But the rest of the code will still be x86 - everything BUT the API calls will have to be translated / emulated. It would be the same amount of work as running an x86 linux binary of an OpenGL game on a PowerPC linux box.
it can't be handled by any input APIs (Win32/DirectInput)... it gets handled directly by the keyboard driver.
Close, but not exactly correct. It gets handled by "msgina".dll, which is loaded before logon, before anything else. msgina hooks the keyboard IO, and then traps any ctrl+alt+del presses before they reach other running programs. Modified versions of msgina.dll can be used to allow other programs to receive ctrl+alt+del presses.
This page gives a brief explanation of how things like Novell catch ctrl+alt+del, by replacing msgina.dll.
What do you think happens as the light bounces off your walls? Unless it goes out the window, it all ends up as heat as the light gets absorbed due to imperfect reflection.
I use the suite. For one thing, the suite has quicklaunch, which was removed from Firebird a while back. Another reason is that last I checked, running Moz Browser + MailNews uses less ram than running both Firebird + Thunderbird. I also like the Moz interface a little more than FB.
No, the actual instruction set is not visible to anything except Transmeta's instruction translation code.
It might be possible to port the linux kernel to their VLIW architecture, and add a kernel module to do the x86->VLIW translation, but I don't know enough about how it works to make any speculations.

You are the traffic jam, but you don't have to be.

That already exists, and has for a long time.

How about an explanation of the numbering system right from the horse's mouth

Under the Debug menu (I think), is an option "Detach all processes", which lets you close the debugger and not kill IE.
I use the suite. For one thing, the suite has quicklaunch, which was removed from Firebird a while back. Another reason is that last I checked, running Moz Browser + MailNews uses less ram than running both Firebird + Thunderbird. I also like the Moz interface a little more than FB.
Why? Do you have more info on this for the curious?
No, the actual instruction set is not visible to anything except Transmeta's instruction translation code.

Low-priority processes can use 100% of the processor so long as no other processes are waiting for the CPU.
