I don't know if I've mentioned that I finally went and checked out a copy
of AoE from the local library. Well, not actually all that local - it was
about half-way to Corona - But anyway, I've just got to the part about the
R-2R ladder, and I _finally_ "get" how those suckers work!

Thank you, Win Hill and Paul Horowitz! :)

Cheers!

Hey, buy the damned book. It's worth it.

Ugly grey color, though.

Don't know about your neck of the woods but the one I saw this afternoon
Click to expand...
browsing the shelves of a new bookshop, was on sale at Ł50.00. Unless an
individual is very well financed then it is simply not affordable. What
price knowledge?.
That book was one of a selection of 12 electronics books and 15 maths books.
They sat next to the racks containing 700 programme users books (yep I
counted 'em and why does a Cisco router course need a total of 6000 pages?).
These in turn sat next to the 'philosophy' section containing a staggering
820 books!.
The magazine area held about 2000 titles. Not one electronics mag' but
spoilt for choice if I was a bartender or flower arranger.

The future is here, looking decidedly rosy and good for business :).

Hacienda Heights.
I just looked at the Yahoo map, and apparently, it seems like
60 miles because the straight line would be over a mountain. ;-)
If you want to see where Hacienda Heights is relative to Whittier,
then look here but zoom to 4:

Recently cruised the Computers section of Borders Books. There were
precisely ZERO books on the hardware of computing, and thousands on
software. A shrink-wrapped set of "Microsoft .NET Foundation" took an
entire shelf section by itself, roughly 8000 pages, for a mere $240.

Makes me nostalgic for the days when mere mortals could write
programs.

Hmmph - I was recently quoted 170 UKP (about $300) for a copy of
an out-of-print technical book.

You still can. Get any version of any subset of Visual Studio (even the $99
single-language one) and lots and lots of documentation is on disk --
everything you need. I think it's also on the web. How does Microsoft sell
those enormous boxed sets of books?
Click to expand...
Some people just deal better with paper books. $240 isn't much for
something that you are going to be spending hours and hours with (no
hooker jokes, please). I prefer them (books), but not to the point of
wanting to pay for them and store them (in most cases- I still have
about 60 linear feet of bookshelves and quite a few files close at
hand, with much, much more in the archives). My two 20" 1600x1200 LCD
panels are still not enough resolution and the reading position is not
optimal in all cases. Maybe I'm old-fashioned, I met a young
entrepreneur this week who reads using a projector aimed up at the
ceiling in his bedroom (or so he says, I've only seen his pretty-much
paper-free office/lab).

But I don't want lots and lots of documentation! That's the point.

Actually, I do program a lot, embedded 68K assembly and PowerBasic on
PCs. Windows is insane... more effort goes into the operator interface
and dealing with the OS than goes into solving the problem at hand.

Since you have it in front of you....
Look up "Floating Paraphrase Amplifier" and tell me what page it is
on.
I do not remember seeing it, but it HAS been a long time.

That's "Floating Paraphrase Parser" and your memory is not playing
tricks.
That is not in AoE; it is in RFC-1855.

But then the program is easy to use, which is the payoff. Do you
really relish the appearance of a DOS screen on a program you didn't
write? How will the editing work? How do you go back to change
something 3 steps back? Ugh.

PowerBasic! When I have any problem that I have to do more than a
couple times, or any fairly complex equation, I just whip out a little
program, and then I can tweak it, and save for future use. I've also
done a lot of analog+digital simulation in PB, like weird semi-digital
PLLs or statistical things. Today I'm going to try my latest:
WAFFLE.BAS, a program that reads an optical signal waveform from a 20
GHz Tek sampling scope, compares it to an ideal target waveform, and
iteratively tweaks a 4 GS/S arbitrary waveform generator to make the
optical waveform match the target. I wonder if it will converge.

If you buy PB3.5, I'll send you some of my programs as examples.

John

Is there a difference between Power Basic and Visual Basic?

...Jim Thompson
Click to expand...

Well Microslop makes VB, and PowerBasic makes PB. PB is actually
evolved from Borland TurboBasic. It compiles anything in about 0.1
seconds and executes something like 20x as fast as VB. It uses the old
INPUT..PRINT paradigm, like all the classic DOS and other Basics.

It is a clean modern language, with all the fancy CASE and WHILE type
structures, formal subs, labels, and pointers if you care for that
sort of thing (I'm a flat, state machine, GOTO programmer myself.)
Inline assembly, too. I like the Dos3.5 version because it has nice
inherent graphics, but there's also the Console Compiler, the 32-bit
version that has the TCP/IP and email hooks and stuff. I've used that
to do stuff like rom image builders that need megabyte arrays. There's
also a Windows version if you'd enjoy learning a few thousand API
calls.

Hey, my arbitrary waveform thing converged the first time I tried it.
Seriously cool.
