The exact LP filter is implementation-dependent, but it should cut everything that's above half the sampling frequency. Then, "instantanuous" sampling is made.
A sampled signal is represented by equally-spaces impulses (delta) of various amplitudes, which is the same as multiplying the low-passed signal by an impulse train.
First, the anti-aliasing filter doesn't just "smooth the signak over the sampling period", it has a much wider effect. Theoratically, it would be a perfect low-pass filter: "sin(t)/t", which has an _infinite_ response (Of course, practically we approximate infinity with something smaller;-) ).
As for using a "first-order linear predictor for digital-to-analog conversion", the cost/complexity of building a good analog linear predictor would far exceed any gain you'd otherwise have...
A "sample" is meant to represent the value of a signal over a period of time, not at an instant in time
No, no, no. A sample is an instantanuous value, not an integration. The reason why sampling is not sensitive to very short (compared to sampling frequency) is that there is normally a (anti-aliasing) low-pass filter before the sampling operation.
As for transmitting the value and "time it stays the same", I'd suggest you first get more familiar with the sampling theory before innovating...

The conventional wisdom being trade with China will ultimately change China's communist ways
I think you don't get my point: what is your problem with communism? The problem with both Cuba and China about dictatorships (sp?) and lack of freedom, not about communism in itself. You have communist dictators, you have capitalist dictators. None of them is better in my opinion.
Communist and terrorists are one in the same in many peoples books. Arabs are not. It's people like yourself whose attempts to associate the latter with the former that is truly disgusting.
OK, I will assume you unintentionally totally misunderstood my point here. I'm saying that those who say "communist=we must eliminate" and thow who say "arab=we must eliminate" ARE BOTH EQUALLY DEAD WRONG. There is currently a kind of "arab=terrorist" witch hunt, a bit like the previous communist witch hunt.
For your information, I have several arab (christian) relatives (so I slightly know what I'm talking about here), but I don't have a communist party membership card.
There has been a HUGE amount of venom spewed in the U.S.' direction on slashdot of late, and I find that distressing.
Maybe that's because Slashdot is not "only american" after all... Come on, get over it. As hard as it is to take it, not everybody in the world loves the United States. Since US has been involved (for better or worse, I'm not judging here) just about everywhere, you should expect that not everyone is happy about that (as shown in the middle easy for example).
While I believe that nothing can *justify* the 09/11 attacks (or the ones before, or any terrorist act for that matter), they can be *explained*. Regardless of what you think is wrong or right (which sometimes depends on you opinion and on where you live), the US couldn't maintain its current foreign policy without expecting any bad consequences. Note that I'm not trying to *justify* the 09/11 acts here (they can't).
I would compare this to the guy (wrongly or not) pissing off all of his neighbors in a "badly frequented" area. One day or another he'll end up with some broken bones. While nothing can justify him being beaten up, the guy sure asked for it...
In the U.S. at least, everyone is certainly entitled to voice their opinions -- including those critical of the U.S. itself. But that doesn't mean everyone that disagrees with you is wrong.
Or maybe you forgot about the US attempt to prevent other nations to trade with Cuba with the (now dead I think) Helms-Burton (sp?) bill.
I wonder why the US is still trading with China, they too are COMMUNISTS! It's funny how you don't even need to say how someone (or some country) is bad, you can just say COMMUNIST... or ARABS, or TERRORISTS (which is probably the same as the previous in the american dictionary). These are just buzzwords, the same as in the McCarty/Nazi/whatever era.
What war??? (Germany+Italy+Japan) vs. (US+UK+France,...) is a war. US vs. Usama bin Laden IS NOT! Or maybe the Oklahama bombing should have been considered a civil war? The thing is you've got a president who's been dreaming of declearing a war just like his daddy did and now he's happy cuz he can...
It's like those people who shout "We must bring Usama back and try him in our courts!" That's absolutely ridiculous. We didn't try Hitler, nor would we have even considered it if we captured him.
Had Hitler not committed suicide, he would probably have judged, just like all the other SS/
Nazi/... is Nuremberg (sp?)... or just like McVeigh was.
So as for you main point: "I'm sick of hearing all of this anti-Americanism on Slashdot.", all I have to say is that you have the right to think the US is the best country in the world and the only real democracy and the country that will protect the world... Just remember that, as much as CNN wants you to believe that it the case, most people outside the US don't watch CNN and often have a slightly different opinion (correct or not).
Yes, that's because MS proposes to install not only Windows, but expensive versions of Office and lots of stuff like that. I think the hardware ended up as less than 20% of the total cost (including software, "support",...).
I'm not that sure. They'll have to choose between 20 PC's with MS software on them or 100 PC's with Free Software on them. Not to mention that with the MS deal, they end up in 5 years with 20 PC and NO software at all.
I think you're doing things in the wrong order. First have the list take off, then if there's too much noise, add restrictions. What you're doing now is like installing an "everything-proof" lock on a house that's not built yet.
What's the point of making the archive private? If you want people to start subscribing/posting on your list, the first thing to do is to make the archive available.

Yeah, but GIF/PNG make huge screenshots.
That mostly depends on the content of your screenshot. If you're using a theme with a lot of gradients, JPG will be smaller. However, when all you have is a couple different colors and large areas with *exactly* the same pixel value (as is common for not too fancy themes and simple applications), the GIF will be much smaller than JPG, with a much better quality at the same time.

Seems like I was wrong about KDE 2 not having anti-aliasing, but my point remains: I think it's bad to make screenshots as JPEG. JPEG is better than GIF/PNG for pictures, but when you want to keep sharp (to the picel) edges and don't have that many colors (compared to a "continuous" image), GIF/PNG are usually better.

Actually, I understand that one of the most important difference between KDE 2 and KDE 3 is anti-aliasing. Unfortunatly, they only have JPEG screenshots, so it's almost impossible to notice the anti-aliasing because of how JPEG works. JPEG encodes pictures in the frequency (DCT) domain, so it has a normal tendency to slightly blur (low-pass) the image (which is OK in most circumstances), which makes is also roughly what the anti-aliasing does.
However, PNG (or GIF, but if you don't mind the patent issues) would have been a good alternative, as it doesn't have that low-pass effect since it just works by quantizing values (colormap) before a lossless compression (which is the patented part in GIF). Anyone have GIF or PNG screenshots?
It isn't enough for RMS to promote his ideas of what "free software" should be about. Now he has to censor everyone else and become the thought police?
