Re: Random Number Generation -----> Hardware or Software?
Q: Is a Pseudo-Random Number Generator's output functionally
   equivalent to a random sequence?

A: PRNG:   The next number in the sequence is knowable with sufficient
           knowledge.  Not being able to predict the number is due to
           ignorance and has nothing to do with 'random'.

   Random: No amount of knowledge will allow prediction of the
           next number.

But your answer is not the answer to your question.  You claim to be an
engineer.  The correct answer is that PRNG might be functionally
equivilent to a "real" random sequence, depending on the application.
For example "monte-carlo simulation" or even an on line casino.  In some
cases the fact that you could predict the sequence is unimportant, and
in others you have no way of finding out enough information in a short
enough time.  And of course in some applications it really is important
that the sequence be truly random and hence unpredictable no matter
what.

So if you are going to set up strawmen, at least knock them down
properly.

Implying what?  Is this sort of remark relevant?

This is the end of this conversation.

Fine.  Don't let the virtual door hit you in the virtual behind on the
way out.

The comment was reflecting on your .sig where you claim to be an
engineer.  Then you ignore one of the attributes of engineering, where
the requirements of the problem are considered when formulating the
solution and proceed to dis prn in favor of true random when there are
many applications in which the difference makes no difference.

Are you sure you are not a Mathematician traveling incognito?

Alas, I re-installed my OS and changed my news reader recently,
and lost much of my killfile.  It won't take long to identify the
tossers and re-plonk them, though - flamers can't stop from being
flamers.

Your accusation is false.  You can examine my posting record and
see that I don't killfile when I am losing an argument, but rather
when someone stops having a reasoned discourse and engages in
personal attacks.  Perhaps you believe that flaming someone rather
than sticking to facts and logic is "winning the argument", but most
people believe that the first person to engage in personal attacks
has *lost* the argument.

If you believe that the above is incorrect, I invite you to attempt
to win an argument without resorting to personal attacks.  You will
find that this will *not* result is a public killfiling.  Then try
a personal attack with no argumnts of any kind attached, and watch as
I plonk you.

What accusation?  I made a neutral statement, not referring to anyone
specific.  The source of the noise appears to be in the receiver, not the
transmitter.

Are you attempting to flame me by unwarrantedly accusing me of personal
attacks?

No and no.  I made a neutral statement about why I killffile.
The fact that it is in a reply to you shows that you have not
engaged in personal attacks - at least not since I changed my
news reader and had to start a new killfile - and thus are not
includes in the class "killfiled."  If you were, I would not
have seen your post, and thus would not have replied to it.

Doesn't this show that the set of prime numbers is the set of random numbers
?

My abilities are such that, for any set of truly random numbers, of
any length whatsoever, I can predict whether or not each value is
prime with significantly better than 50% accuracy.

Well, about 1/2 the numbers will be even, and not prime, so if you guess
that they are all not prime, then you would be significantly better than 50%
