I assume you know of the technique to set the parallel equivalent of all
the resistances on the V+ input to the same on the V- input, so equal
offsets are generated?

Yes. Can't do it here, as the particular circuit has a varying impedance on
the V- input (simple audio mixer).

It's good practice to ac couple that input. Then you won't have loads of DC gain
to worry about. Don't add an R on the +input since it degrades noise.

NE5532 is a typical choice for this application. Use NE5534 if you want slightly
better noise.

Make the mix and feedback R's <10k for a decent thermal noise contribution.

For your own peace of mind, this habit you have of citing "bad"

in the preface to AoE 3rd ed.

Nah, folks are more than welcome to come visit me anytime at my lab

We can do stem-cell research here.


There is a difference between withholding government funding for

Let's not forget all of the "cord blood" research and banking being
done, just for the stem cells. Private research, private monies.

As an example see:
http://www.nysun.com/article/2226

I haven't checked - is there some law against it, or is it just not

getting a handout? Because that's a good point - there are way too
many government handouts, and one of the major problems with them is
the way they somehow transform into "entitlements." Like, I'm entitled
to a chunk of your paycheck, just because the government is doing the
stealing for me.

That 'uber' is maybe significant. Did you recall that even the German

No alternative so long as folks feel the need to vote strategically. (I
wouldn't even *want* a libertarian, but that's another thing.) Change the
voting system and then there will be some chance for good impact, I think.

'memes' is a concept that is used by Dawkins in a set of books on
evolution. Memes represent little chunks of information, which he claims
are affected (similarly to biological systems) by natural selection. His
favorite example is the joke. Its told to others (ie, it 'reproduces'),
competes with other jokes (there is only so much time to tell jokes) and
changes seemingly randomly. As it changes, if it gets worse, it stops
getting told (it dies out), or if it gets better than other jokes, it is
told to more people, thus reproducing itself more effectively.

Actually, memes do not have to be small.
Religion in many of its forms, esp those with extensive mythology, are memetic
in nature.

The Gods are memes with personality.
They can also possess intelligence (although not as we know it etc) as anyone
who has played Ouija can testify.

With that in mind, there is something I've never quite been able to
understand in the character LCD data sheets.

For example, in the canonical Optrex manual
http://www.optrex.com/pdfs/Dmcman_full.pdf
on page 15 (section 1.7.5), and many others where they show the bit
contents of a control byte, there is a row of numbers below the byte; in
this example "123 14444244443 14444424444443".

I'm sure this is crystal clear to everyone but me, but I just can't seem
to decode the meaning. I've implemented drivers for several 8-bit micros
without "getting" it but it is frustrating not to know. Any ideas?

There is no claim, its a fact. Do you copy ideas? End of story.

The phrase "End of story." is obviously a successful, highly evolved

I agree with this, if you take Kerry at face value from what he is saying.
However from the pratical standpoint, Kerry allready has a lot of votes
from the progessive side and alienating these voters would be hard. What
Kerry has to do to win is to get some Bush voters to switch sides. I'm not
going to go into why there are so many Bush voters, my best guess has to

Yeah, like the welfare programs that made the first microprocessors
financed
by
the Feds.


Except that they weren't.

Ok, your right, the 4004 was developed for a calculator. However, how much
university and public funded research went into being able to make the
4040? I should have said the kind of welfare that helped to develop the
microprocessor and made it what it is today.

I could have added the kind of welfare that started the internet.

I think I made my point even with the error!

Not at all. In which case was the value of the money involved increased
by being filtered through three layers of bureaucracy? In what way did
anyone get more bang for the buck by vampirizing the taxpayer to feed
an army of parasites?

I'll go with "That government is best which governs least."
