Tubes do not theoretically provide for a cleaner sound. Theoretically, transistors can do a better job, but audiophiles have been drooling over tubes for decades now anyway. My theory is that they produce a kind of distortion that sounds good to the human ear.
It's strangely satisfying when some smug dork realizes he has been objectively, absolutely wrong. I look forward to it in your case because it will happen any moment now.
I think you missed the point. He was saying that he has actually tried this kind of thing, and it's not easy. (Note that "simple" and "easy" are not the same thing. Sometimes it takes a lot of effort to make something simple enough to work.)
Another idea is to make LegWay stand up (from a lying position) on it's own. It can't do that right now, because the center of mass is below the axle when it on it's side.
With your interpretation of "on it's [sic] side", the center of mass is not below the axle.
This would seem to imply that, in theory, a very large black hole could have rather low density inside the event horizon.
Yup. For any density, no matter how low, there exists a radius at which a ball of that density will be a black hole. Escape velocity is proportional to sqrt(m/r), and for a ball of uniform density, m is proportional to r^3, meaning the escape velocity is proportional to r.
There are theories that our whole universe is a big black hole. (That's not my idea, but I forget where I heard it.) Maybe that even explains the red shift without the receeding galaxies, I dunno.
Say you have one thread running flat out and another that needs to do 100microseconds of work. With 100 ticks per second you will lose 5 usec to context switching and 9900 usec to waiting for the next context switch. With 1000 ticks per second you lose 50us to context switching and 900 usec to waiting for the next context switch. So you get more work done.
This is not true. When a process/thread has nothing to do, it does not just sit around waiting to be preempted. By definition, if it has "nothing to do", that is because it has yielded the CPU. For instance, if the process does 100us of work and then makes an IO call, it will immediately yield to another process.
Sure, there are some poorly-written apps that do excessive busy-waiting, but they are the exception, and there's not much the OS can do about it anyway.
The only benefit of increasing HZ is latency.

BTW, I'd just like to mention a pet peeve of mine. In the article, they mention that "RedHat shipped their 8.0 kernel at HZ=512". There is no reason whatsoever that this should be a power of two, so I believe it should not be. Powers of two have a magical status in the computer world, but I think you should not give your code this kind of connotation unless you have actually decided that a power of two is the best choice. Otherwise, you should pick a number that reflects the ad-hoc nature of your choice. Powers of ten reflect this better than powers of two. Thus, all else being equal, they should have chosen 500 over 512.

No, but if we bring DNA to Venus, then we may never again know whether it developed there on its own. That's why they're going to crash the Galileo probe into Jupiter to avoid contaminating Europa.
I have no interest in continuing a discussion with someone who must resort to calling me stupid rather than simply arguing the facts. If you must do this, please don't bother replying any more. Well-informed, intelligent people frequently disagree on the importance of scientific discoveries.
Expecting to find high levels of carbon monoxide created by sunlight and lightning, the researchers instead found hydrogen sulphide and sulphur dioxide...
Registers in use at the time of the call is always going to be less than or equal to the number of registers used over the entire function. Thus caller-save wins.
Hey, that's a good point. I never thought of that.

I wish someone would invent an HTML tag for ordered lists that would number the items automatically. ;-)
Where did you get the idea that the software is broken?
Just to clarify, what happens to a 0085 (NEL) character when a Unicode file is saved in an iso-8859-1 or UTF-8 encoding?
Gotta love those lating chapital letters.
Here's more info.
Cheers.

I'm sorry, I don't see your point. Are you saying that finding DNA on Venus would not be newsworthy?
"Nano-anodes"? Have I suddenly fallen into a Mork and Mindy episode?
Don't play lawyerball, son. If they found viruses in Venus' atmosphere, that would still be big news, whether or not you consider them "alive".
Well said! I tried to come up with a good response, but I gave up because I couldn't phrase it as well as you just did.
