Low-pass filtering will not reconstruct the input sine wave as you believe. I have uploaded a short
SPICE analysis of the first 10us of the waveforms in your first example, (http://euphoria.org/home/help/nyquist.html)
As you can see, the output waveform after low-pass filtering resembles more closely the "connect-the-dots" stick figure than it does the sine wave input signal.
Site A and C are correct. There is a problem with the url for site B.
Site C shows a nice input/output waveform but does not address the problem of how to achieve it.
Site A and C show you cannot reconstruct a waveform with two samples per cycle. In fact, as one site mentions, if the samples happen to fall on the zero-crossing, the resulting output is zero regardless of the amplitude of the sampled waveform.
Tektronix and Hewlett-Packard use 4 to 5 samples/cycle in their discussions on sampling scopes. The more samples/cycle, the better.
Finally, another human who understands how valuable a real keyboard is. I find the old 84 much faster and easier to use than the later versions. The Ctrl-Alt-Caps keys seem to be located to break your fingers every time you try to use them.
Does anyone know where to get an 84-key AT keyboard these days? I purchased 6 new ones many years ago, hoping they would last the rest of my life.
Unfortunately, I seem to be living longer than planned, and I'm down to my last one.
I was wondering how an IP company with no fab could end up with sweeping patents on all the current memory designs: SDRAM, DDR, RDRAM, etc. How could they do all the work needed to create these technologies, and what was the rest of the industry doing at the time?
The answer is simple. Outright theft. The Register posted an article on Hitachi's response to the Rambus suit. Rambus stole the work of the JEDEC community and patented the information obtained in the meetings.

My biggest problem is finding things that I know exist somewhere on a site. If you could improve searches, you would get a big win.
Another thing would be a simple change to browsers so the do not open a new page as soon as you click on a link. Just change the color of the link to indicate the download is in progress. In fact, the link could be made into a small progress bar showing how much of the download was complete.
That way, a viewer could select several pages he wants to see, and go to the first one that is ready.
This would save a lot of time on long SlashDot pages!
Clearly fraud. If you wanted to track someone this way, you would have to add a precise atomic clock for timekeeping, and put them in orbit so all the GPS software would function. Not very practical.
They are deliberately misleading investors with buzzwords that sound interesting, but cannot possibly lead to anything.
Another example - they predict the market will be worth 100 billion dollars. They give no justification for this figure, or even define a relevant market. But if you are going to protect a 100 billion dollar market, you need more than one single patent. You need thousands.
Clearly, the real problem is the limited range of numbers used to moderate a post. This can be fixed.
I propose increasing the range from the current level to plus and minus infinity.
I realize this will create problems when post approaches either limit - it will take the entire computing capacity of the universe to express the number.
But hey - computers are getting faster every year.
Also, the actual limits at infinity should be reserved for direct correspondence from dieties and representatives of higher powers.
These people know who they are, and will have no problem adjusting their level no matter what we do.
Agree. I understand the desire to maintain freedom of speech and avoid the appearance of censorship, but this crap is getting out of hand. It is wasting everyone's time and making./ look foolish.
Why not specify "Fair Use" conditions that automatically assign a special category to "first post" and the use of profanity. And enforce it.
If anyone want to read this junk, they can change their filter limits. The rest of us shouldn't have to put up with it.

Correction. Site D shows the nice input/output waveforms.
Had it correct in the original, before Windows crashed.

Sounds like they took a page from the Microsoft operating manual.

It looks like Microsoft may follow the Open Source model in the dozens of suits pending:
1. Settle Early
2 Settle Quick
MRM
Trying to store the date as a byte doesn't save memory.
If you use the word alignment option in your compiler, it still takes up 2 or 4 bytes depending on the definition of a word.
If you don't use alignment, you pay a severe penalty in accessing variables.
His bio claims he has 11 patents.
A search at USPTO for "DR. RANDELL MILLS" as inventor gives the following result:
Searching 1976-1999...

A search using "RANDELL MILLS" gives the same result.

It is violation of Patent Law to claim a patent has been granted when it is still pending.
