Well, you need at least some digital logic to convert it
into a number. There is a paper by intel on their design for
a random number generator based on such noise sources.

That would be all of them in this case. :-)

When you deny that important numerical algorithms were developed in a
particular language, how is the dispute not about the development of
algorithms?

>But if you want original development, try

You still are doging the point in dispute. Nobody claimed that everything
was developed in Algol, that most algorithms were developed in Algol or
that Algol was the first language to be used to develop algorithms. You're
attempts to change the subject remind me more and more of your friend
David Frank.

Sampling speed is another critical factor. If sampling
exceeds the bit flip rate, then it becomes less "random" ;-)

Here's another example.
Don Shell published his algorithm in machine code.
(A High-Speed Sorting Procedure, CACM, July 1959, p. 30-32.)
