A bunch of people have posted silly questions about what happens if they get a crash or a virus or something.
All you'd have to do is to have something on the motherboard that resets the memory.
Then you'd have the normal shutdown/reset buttons, and then another button (or combination thereof) that would also wipe the memory in case of bad stuff.
So now not only do they want to take over our computers, they also decide what they want us to say and type?
I mean technically they can put whatever they want in there, but I would have thought that anything calling itself a thesaurus would actually contain a significant fraction of commonly used words and terms. Even the OED has swears in it!
What happens when they do this to the french version? The quebequois will have every second word missing....
Sorry, while it may be true for Pentium series, it is not true for SMP in general.
1) It is actually possible to get better than linear improvement under certain conditions (like if something is already in a shared cache because it was fetched by the other cpu).
2) It is possible to have each cpu schedule itself based on contents of ram.
Yes, there is overhead of having two cpus, but it is very variable dependent on OS and workload.
As long as the gravitational force is exactly opposite and equal to the thrust from the engines, you'll feel no net force. So the greater the engine thrust, the closer you bring the black hole.
Of course, it would only work for a single distance from the black hole, so it wouldn't really work for a plane full of people. And you have to waste energy accelerating the mass of the black hole as well.
No, you have to make the source available to the people to whom you have distributed the software. At that point there is nothing stopping *them* from giving out the source.
There is nothing in the GPL that says I have to give away source to anyone that asks...its just that this is how most people have chosen to do it.
I can charge you a million bucks for my program, but at that point you can then turn around and stick the source up on the internet. There's no guarantee that anyone else will pay for it because they can get it from your site, but there is nothing wrong with me charging a million bucks for them to get the program from *me*, as long as I make the source available to them.
Oh? Why is that? If you can get an unloaded pair between two locations, there is no technical reason that I know of (and I work in telecommunications) why you can't put a DSL modem on each end.
Please explain further with technical objections.

Its not just 35mm cameras that have depth of field--the human eye also displays this effect.
If you hold a finger up in front of your face and focus on it, then anything further away will be blurry.
Yes, the effect is minimized in digicams due to the tiny distances involved, and you'll find that there are a great many photographers using digital cameras who are sadly disappointed by the lack of depth of field.
However, in a computer game I don't think it has any point, because the game doesn't know where you are looking and hence doesn't know what should be in focus. If you were using VR goggles, maybe, but on a normal monitor its useless.
I agree with you that copying material of which you do not own a copy is not allowed in the US.
However, your DVD analogy is flawed. CSS does not "prevent those pirates from bootlegging". It has always been possible to make exact duplicates of the encoded DVD disk, and those copies will play on any DVD player. CSS simply controls who can view it, not who can copy it. The analogy is more that you are charging more for your product in one market then in another and someone figures out a way to import the cheap product to the expensive market.
As for Dmitry, you missed one tiny little thing: Dimitry is russian, and what his company was doing is completely legal in his country.
If you plan your architechture properly, five 9's is not impossible. Redundant equipment, with redundant interconnects, in different physical locations, can achieve (with some work) this kind of reliability. For some telecommunications (911 service, for instance) five 9's is the minimum acceptable level.
It certainly is true. The reasons why there are so many overflows in new programs are that 1) people are lazy, 2) people copy old code, 3) people don't know about it, 4) people don't care (ties in with 1).
Ah, but what you're missing is that it is exactly those broadband providers that want to muscle in on voice traffic. Compressed VoIP only takes 8-13kbit/s depending on what codec is used, so this is a relatively small amount of bandwidth even when compared to a (say) 60Kbyte/s upstream cap.
There is a product already out there for cable companies that takes one cable in and gives 4 phone lines, an ethernet connection, and 2-way digital TV. You can just bet that your local cable company would love you sign you up on this...
So we convert the problem from scanning a spatial array to scanning a frequency array. Don't we still have to analyze the frequencies to figure out which one has been altered?
I suppose that each frequency could go to a parallel detection array, which would then drive some sort of interrupt, however this would seem to become unwieldy as the problem space increases.
Can someone explain further just how the detection of which frequency of light was changed would actually work in practice with a large problem space?
4. If you modify the software or create other software that links against the GPL'd code, your new code also falls under points 2 and 3.
This is the viral aspect of the GPL, as it means that the original GPL'd code "infects" any new projects in which it is included, forcing them to be released under the GPL as well.
Hold the visor in your hands while jotting down notes, and talk into the headset. You get better sound quality than talking into it directly, and the convenience of being able to take notes and talk at the same time.
I think that people are focussing very narrowly on what the definition of an "embedded device" is, so much so that they overlook certain things. Embedded systems are not only tiny things with a few KB of memory...
For instance, a compact PCI board with a G4 chip and a Gig of RAM with dual 100Mbit ethernet ports runs Linux perfectly well and qualifies as an embedded system.
In a case like this the firmware loads the kernel and ramdisk image off a bootp server, you NFS-mount whatever else you need, and whee! you've got a system that is technically embedded and yet can be easily upgraded.

In case people can't read, the previous record was 255 degrees C BELOW zero. The new record is 200 degrees C ABOVE zero.
Where's the problem?
A few points:
Have you ever
a) done audio editing
b) done video editing
c) applied a filter to a 50MB+ image
d) compiled X
e) done any ray-tracing
etc, etc.
Any of these things can suck up vast amounts of horsepower and beg for more.
Also, 2.4 is getting somewhat more sane in recent releases.

Yep, straight out of the Tolkein parody "Bored of the Rings". Can't remember who published it though.
You might want to rethink it a bit yourself.
