Here's a useful technique to ease and speedup conversion
of bitmaps into their PostScript vector equivalents:

Temporarily scale the bitmap to exactly ten times the
number of pixels of vector width.
Then flip it vertically
so that the numbers increase from the top.

Locations of all the PostScript vector elements can be
read by using the pointer for locations, and the box
select for widths. Mentally divide by ten to get your
new PostScript coordinates.


I'll try to work up a demo on this whenever.

There are both powerful advantages and disadvantages to
doing a "Level II" ebook remastering by combining Acrobat
10 with my Gonzo Utilities.

As this new demo clearly shows, Level II is markedly superior
to results you would normally get by using Acrobat 10 alone.
A comparable Acrobat 10 only result appears here.

Files are much shorter and text quality is much higher. Far
fewer fonts are normally required. Full text searching is
provided and maintained through later rework. Image
appearance is much better, and, despite high compression,
can be arbitrarily magnified to any desired resolution without
degradation. Value-added features such as full color, web
links, hyphen elimination, emphasis substitution and such
are easily included. Fill justification is easily preserved
with only the most minimum of text rekeying. Halftone
images are greatly improved and can be made text searchible.

Turning to the disadvantages, if there is some historic, legal,
or IP reason an exact replica of a precyber source is needed,
then the method is largely inappropriate.

Secondly, it is tricky to do more than four or five "easy" Level II
rework pages per hour. Some pages ( especially electronic
schematics ) may take much longer. Thus the project has to be
reasonably profitable
to justify the time and effort. Similar,
problems arise iif many new ebooks are needed in a short time.

Finally, the uniquely high quality of the Gonzo Utilities is based
on them being proudly non-WYSIWIG. If you are not into
"bare metal" machine language programming, then they might
not be at all suitable for you.

We do offer custom Level II rework for both current and
pre-cyber ebook projects, as well as training seminars. You
can email me for details or call (928) 428-4073.

There's some interesting and sneaky tricks you can pull if
you add some unprinting spaces to the justification routines
in our Gonzo Utilities.

The rule is that all leading line spaces will be deleted. If
in the rare instance you want to add leading spaces, preface
them with a |j or |k
. Or both if your layout is extremely
critical.

If you want to force a fill justify on the last line of a page,
add as many spaces as you need, and follow them, again, by
a |j or |k
. Naturally, this takes a last line that is "nearly full"
to start with.

If a command ends up at the end of one line and the action
is supposted to begin on the next one, the command may be
ignored. This can be a problem with web links or bolded
emphasis. The cure is to add one or more spaces to the
end of the previous line
. This will force both the command
and the command action to be together as they belong at
the beginning of a line.

Beyond this tutorial, the best way to study Gonzo is to
view most any of the .PSL files in our GuruGram Library.

Here is a brief example of the benefits of combining  
Acrobat X with my Gonzo Utilities for "Level II"
eBook rework. Full 16K sourcecode is found here.

The improvements in file size, text quality, image quality,
new value added features, and preservation of searchibility
can be stunning.
Especially when starting with a pre-cyber
textbook.

The original Acrobat-only remastering can be compared here,
starting with page 9.

The process begins by scanning the original book pages to
Paint, and transferring these to Axcrobat X for a Level I
eBook remastering. . The text only output is then fed to
the Gonzo Utilities where a "standard font" conversion
can be done much faster, simpler, less infuriating, and more
conviently than redoing a fill justification from within Acrobat X.

Note that no text rekeying is required! When needed at all,
text mods are usually quite minimal.

The benefits of this route is that all text is now unicoded,
and very few fonts will need embedded. Full searchibility
is preserved, even after repeated PDF-->PostScript-->PDF
improvement steps. Text appearance over ClearScan is
generally significantly improved. And Gonzo's three stage
progressive microjustify does a better job than the
original phototypesetting could manage in the print book.

Since exising fonts can be shared, additional text-only
pages can add as little as 2K to your final file sizes.


Value added features are easily included. One example is
to replace italic fonts with tinted and bolded text.

Background speckle vanishes without a trace.

Bitmaps can be improved or outright replaced by

short and compact "raw PostScript" routines. The
original gray halftone boxes did not look all that great and
got considerably worse if you attempted Acrobat's
reduced file option. These got replaced with some
raw PostScript routines that offer color tints, smaller
file sizes, and much better appearance. They also
add full text sarchibility
, which was not available in
the Acrobat original conversions.

The original B/W "pen and ink" drawings were converted
to full color. Mostly in a fast process involving the bucket in
Paint. With care, full color can often end up smaller than
the untined original.

A dilemma exists with Acrobat X's reduced font size
option. In that it largely prevents decent magnification
of any image.
An interesting value added workaround is shown
in our example. In which any size reduced original can be
click expanded into a web delivered master image of
arbitrary quality and appearance. All done with only
a few dozen bytes of additional .PDF code.

Consulting and conversion services available.

December 23, 2010 deeplink respond

Bingo! And Eureka! and Hoo Boy! I may have found
solutions to many of the limits of Acrobat X. For files
that are much smaller, fonts that are better looking,
and new value added. While fully preserving searchibility.

Just use ClearScan to output text to my Gonzo Utilities.
The fill justification font replacement in Gonzo is ridiculously
easier to use than the klutzy and infuriating text replacement
routines in Acrobat X. But you will still have to decide
exactly how much time and effort is justified for what
degree of improvement you want to achieve.

Switching to a standard font eliminates all the hassles
of non unicode and losing the ability to search after a
PDF-->PostScript-->PDF rework.
Better yet, if you
are using ClearScan fonts on a page-by-page basis, there
may be thousands of these in a 300 page precyber
eBook with manditory embedding. Replacable by three or
four fonts total that may not even need embedding. For
a ridiculous reduction in final eBook file size.

Text quality generally goes up somewhat. The Gonzo
Utilities
normally are a very good match that go beyond
the original fill justification. And, while seldom needed,
can force a rare mismatch with either an extra space
or negative kerning.

You can decide how many of which type of images
to improve. Ferinstance. an image might be colorized
and offered in the small size Acrobat "do not exapand"
extreme compression. While clicking on it can give
you an arbitrarily larger and better direct web access
for only a few dozen bytes increase in .PDF file size.

Fax style gray boxes can be replaced with raw PostScript.
For benefits of dramatically smaller file sizes, much better
looking uniform color tints, and new full searchibility.

Other images can be left alone, retouched, or replaced
with raw PostScript for similar benefits. Dramatically
improving most Pre-cyber book remastering.

I'll try to work up a demo on all this in a few days.
The Gonzo Utilities are, of course, proudly non-WYSIWIG,
so they clearly are not for everybody.

Found a few hundred more feet of the Mud Springs
Canal
, acutally inside the "black hole of Central". The
full story is eventually likely to unfold as follows:

The Mud Springs canal is 7 miles long and a feeder to
a 3 mile long Jernigan Canal.
It likely sources from far
up Ash Creek
. Its early portions remaiin unverified, But
a rancher's PVC pipe verifies the route credibility and
there is no sane alternative to "Where else could it
have come from?
"

A case can be made that this was possibly the first of
at least a dozen prehistoric canals. Owing to its entire
route being viewable at once from certain points. And
to the absence of certain fancier features, unusual
terrain, and nonobvious routes of the others.

There is a short stub canal that apparently dumps into
a wash midway at the Mud Springs Expressway crossing.
A possible explanation is that this is for mud control or
dealing with flood overflows.

Further downstream is a large and failed flood control dam.

Smaller and different from Allen Reservoir. The dam completely
runs roughshod over the canal without any accomodation of
any type. Which suggests extremely strong evidence that the
canal is in fact prehistoric
.


A very well definied "hanging" portion follows, going "up"
a wash wall to continue. Just past where the canal once
again reaches the bajada is a strange circular structure.
Very pithouse looking, but probably centuries newer. And
only half a meter from the canal. Until proven otherwise,
this is the "troll house".

Somewhat further southeast, the canal appears to branch to
source the Jernigan Canal. Evidence in this area is somewhat
weak and consists primarily of long linear arrays of dead flowers
combined with the same linear array studiously avoided by the Creosote
Bushes. But all three ends connect to more credible evidence.

A small spur in this area leads to a small and obviously Anglo
tank. This is presumed to be a "steal the plans" and "dig
out an old ditch" similar to Hawk Hollow Tank.

The two canals parallel each other for a surprisingly long time
over very minor spacing. Presumably this was needed as a
"setup" to maintain slope on the two routes. The canals
never seem to get more than 800 feet apart. Sometimes
much closer.

The west spur vanishes into the Black Hole of Central to
emerge as the well defined Jernigan Hanging Canal. The
east spur also vanishes into the Black Hole of Central to
emerge as a well defined continuance that appears to
be headed for river bottomland near the Union Canal.
The final thousand feet is indistinct and largely trashed.

Slopes and terrain inside the Black Hole are eminently
credible. Possible explanations for the absence of hard
evidence are incomplete exploration, sheet flooding, or
stream piracy.

Meanwhile, the Allen Canal enters the Black Hole of Central
from the east. Where it goes and whether it merges with the
Mud Spring canal has yet to be determined. The only other
route would be unlikely as it is heading towards a cineaga.

Kiddies, we are dealing with utterly spectacular world class
stone age engineering here
. Orders of magnitude beyond beyond.

Yet, with one or two grateful exceptions, I cannot seem to interest
the powers that be in the Southwestern Archaeology hierarchy.

Just because I skipped one too many compulsory faculty teas
half a century ago.

At one time, it was outrageously expensive to add color
on top of black and white printing. These days, adding color
to a web ebook reprint is almost trivial. And possibly
second only to live links as potential value added.

Consider these before and after examples. The color version
was done in something like twenty minutes using the bucket in
Paint. We've saved these as .PDF files. Amazingly, the color
version is slightly smaller than the B/W one at just under 200K.
If you do not need click-expand, the Reduced File Size option in
Acrobat can get you down under 24K. And that is with all PDF
overhead .

Some tips: It is common in black and white "pen and ink" drawings
to have white breaks between foreground and background.
These should be eliminated during colorization. One of the ruder
surprises of the paint bucket is that it will "break out" and trash
everything with even one pixel of true white on its border. Always
build "fences" in black or the pour color before using the bucket!


Also, do any resizing or rotations after colorization. Otherwise,
light gray "sugar" is likely to appear. The bucket demands
pure white in its pour area.

Be sure to move the Print Production option into the
Tools menu on Acrobat X. The Preflight Report
Generator
is exceptionally useful. It shows you
each and every font and each and every image
in your file, along with great heaping bunches
of other stuff.

Usually after you have done a preliminary upload
of an eBook, you will want to improve the viewer
experience and reduce the file size
.
How much
time and energy you are willing to spend on
this task very much depends on the potential
value and income return on the posting.


While replacing bitmaps with raw PostScript is
the obvious way to do both, at present I do not
know how to do so without trashing the PDF
search ability. Clues appear in the toUnicode
objects and in Adobe Tech Note 5411.

While Acrobat X Pro's ClearScan does an amazingly
good job at replacing fill justified fonts, it seems to
degrade halftone images, especially gray fills.
These can get unacceptably bad if you use them
with Acrobat's Reduced Size PDF option.


I'm working on a mod to the Bitmap Typewriter
that should allow easy replacement of a gray
halftone with a true gray. This should also allow
text searching, and might provide for color tints
with only a modest file size increase.

Another glaringly obvious problem: New ClearScan
font glyphs are created for each and every page.
Which means that an eBook might have several
hundred "nearly identical" embedded fonts. The
workaround involves substituting one full and
complete and properly uniCoded font on each
and every page.

I'm not yet sure how well fill justification can be
preserved with font substitution.


The Preflight Report may reveal images that are supposed
to be text. These can be gotten rid of by retouching
the original scanned page bitmaps in Paint.

Exporting from Acrobat X to a bitmap can be an extremely
useful tool. You can adjust and edit the bitmap or even change it
to very compact raw PostScript code.

But doing so with the default settings may lead to ratty text, even
after a ClearScan pass during the .PDF reconversion.

The workaround is to get into Preferences-->Convert from PDF
and change either .PNG or .TIFF resolution from Define
Automatically to 600 DPI or higher.

This may lead to enormous file sizes that may need later
adjustment.

December 16, 2010 deeplink respond

If you manipulate bitmap BMP files with Paint or
Imageview32 before sending them to Acrobat, you
may end up with figures that are wildly the wrong size.

The usual cause of the problem is a resolution forced to 96
DPI or missing entirely from the .BMP header.


A simple workaround is to get into Irfanview, then select
Information, and change the header .BMP resolution to whatever
is needed for proper scaling. Make sure this is the last thing
you do before sending the file to Acrobat!

Note that this often will give you much higher final quality than
a simple size reduction . The more bitmap pixels Acrobat has to
work with, the better the final quality.

December 15, 2010 deeplink respond

I've been exploring the new Acrobat X. One of its new
features is an option called "Save as Reduced Size PDF".
An average size reduction of 30 percent is claimed.

Aparrently part ( or possibly all ) of what it does is apply
some sort of extreme compression to any non-text bitmaps
remaining on the page. I found some page files going from 70K
clear down to 29K.
That's the entire .PDF file, not just the
image!

It apparently can do this without degrading "average"
bitmaps. But I found this file reduction scheme unacceptably
degrades some
B/W halftones. Especially ( particularly in the
case of a light gray fill ) halftones that are already marginal.


One workaround seems to be to apply file reduction selectively
only to those pages that give acceptable results
. A second
is to get rid of the halftones, replacing them with grayscale or
full RGB images. Or raw PostScript artwork.

December 14, 2010 deeplink respond

Picked up a Garmin eTrex H personal GPS navigator. It is
proving extremely useful in the Prehistoric Canal
explorations
.

Ferinstance, I can get the GPS coordinates of a place I
want to go off of Acme Mapper. And then go to it
with the eTrex. Or record where I was, again to
Acme Mapper. Or set a waypoint for my 4Runner
in heavy brush and be able to return right to it.

Or purposely cover a loop route to explore twice
the terrain without worrying about exactly where you
are at all times. There also seems to be a highly
subjective "focus factor" that makes it easier to
cover more ground faster with less energy.

List price is around $100. Accuracy is typically
about ten feet. But you can dramatically improve this
by going to differential GPS. Either with a second
unit or a web or commercial service. Differential GPS
works by tracking the reported position of a known
fixed position over time. Correnctions are useful over
tens or even hundreds of miles.

The five buttons make entering alphanumeric data a pain,
but are otherwise intuitive and ergometrically useful.
While the buttons are intentionally hard to press, I
feel they overdid this "feature".

Also nice is reporting such stuff as distance and speed
traveled. As with most GPS, the altitude resolution is
rather crude and largely useless. Hundreds of waypoints
can be saved and stored for later analysis.

More on similar projects here.

December 13, 2010 deeplink respond

It is the tiny details that sometimes can get to you.

Each tiny speckle on a scanned B/W Acrobat original can cost you
over 200 bytes in final file size
. Owing to the object calling a
CCITT Fax Decoding. A dozen of these per page on a 200
page book adds up to half a meg of extra .PDF final file space!

You can spot these by viewing the .PDF file in a text editor
and searching for CCITT. Rows and rows of these means
you have a problem. These also will clearly appear when
you do a preflight report.

One workaround is to scan first to Paint and carefully
remove all the obvious glitches
. Plus, of course, keeping
your scanner glass squeaky clean and unscratched at all times.


Here's a sneaky way to find any hidden glitches: Get
into Acrobat and edit objects
. On a temp work file, delete any
known images, then any known text. Only the glitches should
be left. Remove them by retouching the original bitmap.

The plot thickens till it clots.

There is a 3000 foot or so square patch here I think I'll call the
Black Hole of Central.

Two prehistoric canals clearly go in, and two clearly come out.
But there is not the slightest trace so far of anything inside.

Possible explanations......

1. I could not find a pig in a dishpan.
2. I'm looking for the wrong things in the wrong place.
3. Massive sheet flooding in the past.
4. Stream piracy.
5.
Modern trashing.
6. There never was anything there.

I guess I'll try full transects over the non-obvious portions next.

What is really frustrating is that straight line extrapolations
suggest the two canals cross at right angles!

Two useful tools for eBay image prep and other postproc
are the open lasso and the octant remap.

Replaing the background on any sloped line or curve can
be painful. Instead, use the lasso to grab a portion of the
new background, being careful that its "open" slope
between its start and end nearly matches the slope
you are trying to match
.

If you are working on edging something circular, get a 45 degree
portion of it exactly the way you want. Then flip and rotate
to build the full circle
.

This should be nearly eight times faster than rebuilding the
entire circular outline. If you are careful with your flip and
rotate sequence, each new paste will exactly match the
mirror edge of the previous one.

Here's a method of restoring faded, scuffed, or partially
missing pages such as back covers that can be most
useful when remastering classic books for ebook distribution.

It takes no special skills or software, but is rather labor
and time intensive.

First .BMP scan the cover or whatever in RGB to the highest possible
resolution, preferably 600 DPI. Then get into Paint.

Find the best lowercase "a" on the page and improve it as
best you can. Also upgrade its background. Save a copy of this
letter to a separate alphabet stash.

Copy the letter to your clipboard and use it to replace each and
every other "a" on the entire page
. Then repeat for lowercase
"b", and so on through the entire alphabet. If several fonts are in use,
repeat for each and every font.

If the lettering is really bad, symmetry can help. As can building
new letters out of portions of older ones. Sometimes letter groups
or whole words can be used to make the process slightly more
efficient.


Plain old cut and past techniques can then be used to repair any
background between the letters.

Do the usual gamma, brightness, contrast, and sharpness adjustments in
ImageView32 or Irfanview. Then send your bitmap to Acrobat 10 for
.PDF conversion.

You may or may not want to try ClearScan. This may degrade the fonts on
subtle colors or strange art or few characters. But will give you full text
searching. ClearScan works amazingly well in black and white, but tends to
choke on pastels or anything mottled.

Going from .PDF ---> PostScript ---> PDf while doing
a book remastering has all sorts of stunning potential

A process we might call "un-halftoning" can dramatically
improve most halftones used in book remastering.

Rescan the book pages to the highest possible resolution

This should produce very large oversize halftones. Reduce
the images down to their normal size using ImageView32
or Irfanview.

Poof. All the halftone stuff should vanish as resizing does
its thing with bicubic interpolation. Instead of a black ink
halftone approximation to an image, we have a full gray
image approximation to a halftone!

I'm wondering if the real underlying cause of all of the
perpetual motion ludicrosities of the past few years is
a total failure to understand Fourier Series.

Just about all of the scams and stupidities in one way
or another involved "pulsed dc".

The only tiny problem with this is that there is no
such thing as pulsed dc!
You instead have a waveform
with various ac and dc terms. More often than not,
each term can be separately considered and evaluated.


Ferinstance, only the dc term in a pulsed waveform
( or ac terms that rectify to a dc component ) plays any
role whatsoever in
electrolysis. As guaranteed by
Faraday's Law.

Any low duty cycle waveform is exceptionally easy to
mis-measure, owing to its strong difference between its
average and rms values. Invariably, the wrong measurement
will be low

I still do not have conclusive proof that the prehistoric
Mud Springs canal
exists.
IF it exists, it would be
one of the most significant of Mt Graham water
exploitations. Routing the highest flow rate stream
of Ash Creek "up" and over the largest and most obvious
bajada.

For a projected length of five miles! A case can be
made that this might have been the earliest of the
canals.
Based on the entire route being visible from
its starting point. Which would vastly simplify its
engineering.

The evidence so far: There is an obvious and
( largely ) unarguable half mile solid chunk of the
canal halfway along the route. It even includes
a diversionary canal stub presumably used for
flood control or mud removal.

The Jernigan Canal provides an obvious teminus
for the Mud Springs System. It too is well defined
and unambiguous, but only a quarter mile long. But
any intermediate evidence has yet to be found.
And another canal is within 800 feet but defies
any and all interconnect attempts.

The only rational source for such a large canal
system would seem to be Ash Creek.
And a
rancher has laid a PVC pipe along the route,
both proving its feasibility and raising "stole
the plans" issues.

But once again, any early or diversionary
evidence has yet to be found. The topography
is certainly feasible. 4WD access is rough.
Miles are foot only.

That's not a bug -- its a feature! Going from Acrobat PDF
to PostScript back to PDF can give you all sorts of file
size and image quality improvements. But I was mystified
as to why any search ability was lost in the process.

It turns out that ClearScan glyph search linking is intimately
linked to ClearScan itself.
And that ClearScan demands a
bitmap input and will not work in the presence of other fonts.

Sadly, I do not yet have a reasonable workaround. Font
substitution does not seem to make any difference. And
outputting as a bitmap and reClearScanning would negate
any PostScript benefits.


I have a hunch this might be an unintended side effect of
trying to protect the IP rights of the original fonts.

It will still be several days before I can determine if the
Acrobat 10 behavior will be any different.

November 17 , 2010 deeplink respond

Many hints as to how ClearScan operates can be found
by exporting the .PDF file to PostScript and viewing the
results in an editor or word processor.

Apparently each encountered glyph is numbered with
a sequential name, such as /000, /001, /002 etc. These
names are directly used in a xshow loop.

Even if font substitution is in use, the names remain
the same.
Thus the ClearScan text imaging is fundamentally
different from the usual alphabet based xshow loops.

But surely somewhere there has to be a table matching
glyphs to the font alphabet
. Finding and understanding this
process remains a major mystery.

Found a rather strange local cienega. One that gives
credence to the theory that there were a lot more
springs in the area and they were a lot larger than present.


This one is strange. It has reeds and breifly flowing
water. The water does not appear bitter or warm.

There are no obvious signs of anything prehistoric,
although it is only a thousand feet from a fairly major
habitation site. Curiously, there are no signs of modern
development as well. Such as fences, traps, dams,
or diversions. It is "just there".

An interesting question is whether the Allen Resevoir

"Truth is stranger than fiction" gets even more bizarre
when you wander into Western New Mexico.

The Brushy Mountain Radar Station is South of Mule
Creek at the end of a secret mountain laboratory road
whose access is easily controlled. It started life as a
cold war facility and presumably still sees use for drug
interdiction activity.

Little known is that it includes oversize kitchen and
dormitory facilities. It was supposedly used as a remote
retreat by both the Kennedy and Johnson presidental
administrations. Since then it occasionally has seen such
mundane uses as BLM team building excercises.

BUT and IF you needed to stash some super secret stuff
( such as, say, some extraterrestrial aliens ), the facility is
virtually ready to go.

Even stranger is Terrortown, once known as Playas. This
began as a company town for a long defunct smelter

the Department of Homeland Security for a training
facility for counterterrorism and urban hostage situations.

Truth can certainly be stranger than fiction. As a bunch
of Gila Valley happenings over the years can attest.

One of the most blatant scams was the McEniry Tunnel,
a scheme to tunnel all the way through Mt. Graham.
The gold and silver could simply be scraped off the ceiling
into ore cars, greatly simplifying extraction. At the same time,
zillions of acre feet of water could be recovered, along with
great heaping bunches of electricity. Plus lots of timber.

The entire prospectus, of course, was an outright lie. The
Grahams are precambrian intrusives with virtually zero
mineral content whatsoever. The site today is a plain old
short mining tunnel.

BTW, all the locals have their own favorite spelling and
pronounciation of "McEniry". And love to argue about it.
I'll stick with his signature on the above prospectus. This
is also sometimes called the "Triumph Tunnel Site".

Somewhat further west was the Spenazuma Mine, shortened
from getting "them" to "spend their mazuma". And a
classic example of blatant salting. Today, this is on a private
ranch on which visitation is strongly discouraged.

What might or might not have been a scam was the Bear Flat
Irrigation District.
In which artesian water was run over a
long series of canals and lakes in what today is totally barren
and dry as a bone.

More modern is the saga of the Banana Farm scam. Which older
Thatcher residents do not want to talk about. Also, for some
strange reason, nobody but nobody in the entire Gila Valley
wants to talk about the "Golden Letter" scam whose pyramind
scheme flushed out the entire area during the 1980's.

Yesterday's canal chasing was more or less a debacle,
missing the intended locations by a few hundred feet.

We did more or less prove that the Mud Springs Bajada
route seems viable
and that a rancher ran a pvc pipe
over pretty much the same terrain in what sure looks
like "steal the plans" to me.

The premise so far: If "they" in fact were to exploit every
drop of Mt Graham water, their crown engineering jewel would
be routing Ash Creek water "up" and "over" the Mud
Springs bajada
.

So far, there is a half mile of mid canal "proven" to well beyond
acceptable on-ground evidence. And the Jernigan Canal
"needs" a water source that is topographically compatible.
But any linking proof remains elusive.

Meanwhile, the only feasible source for the mid canal would
in fact be Ash Creek. But, again, linking proof remains elusive.

Just got an email from someone wanting to make a hot
chassis guitar amplifier "safer" by adding an isolation
transformer.

My response, of course, is DON'T EVEN THINK OF IT!

If the amplifier was hot chassis, it was done so to keep things
as cheap as possible. No way could it have even then sounded
decent. And it certainly would not have improved with age.

Low end leaky capacitors, single ended pitiful output, excess
heat, lots of hum, and all. The basic premise of the circuit was to only
moderately electrocute the guitar player
in order to save a
few pennies. The circuit was so bad that special protection
was needed for the preamplifier tube!

An interesting collection of tube type el-cheapo amp schematics
can be found here. Most of these are not even appalling.  

If you like the hum, noise, and distortion that a tube type amp adds
to otherwise clean audio, that's fine
. But the way to do it these days
is to start with a decent Class D solid state amp and add a DSP chip that
purposely emulates your choice of make and model of tube type
hum, noise, and distortion
.

Which, of course, would only be an approximation, because no two
tube amps of the same make and model ever sounded exactly alike.
You can beat this with a decent pseudorandom sequence generator.
Turn the crank till it sounds right.


Best avoid electrocuting the drummer. Better they die in a bizarre
gardening accident
.

Adobe just announced what they are variously calling
Acrobat 10, Acrobat X, or Acrobat 2010. Supposedly
it has further improved its already outstanding ClearScan
OCR techniques. The new code is supposed to be a
lot faster. more compact, and even better looking.

I'm still trying to find out if an Acrobat 9 glitch is a
mistake I am making, a serious bug, or an intentional
crippling:
An obvious post-processing improvement in
acrobat is to replace certain bitmaps with raw PostScript
procs
that are better looking and far more compact. This
also allows substitution of different types of bitmaps,
particularly to improve and upgrade a halftone.

At any rate, if you export from Acrobat 9 Pro to PostScript
and then import back to Acrobat 9, everything works just
fine, except the search ability is completely lost! It is as if
the mapping betweeen the ClearScan glyphs and their
underlying English letters never gets properly exported.

Meanwhile, the cheapest quasi-legal way to buy Adobe
is through the Academic SuperStore. These folks will demand
something that looks vaguely like a pay stub from a school.

Another route is to pick up an older version of Acrobat at
an auction or wherever and then buy and install the much
cheaper upgrade.

At one time, the only popular ways to emphasize text were
underlining, italics, or bolding. Of these, underlining was the
only reasonable option available for hand writing or an
ordinary typewriter.

These days, of course, underlining should be tolerated in the
sccond grade, strongly discouraged in the third, and severely
punished in the fourth. Fortunately, most compulsive underliners
eventually grow so much hair on the palms of their hands that
they no longer can type.


Since color is now essentially free, it has largely replaced
traditional emphasis forms. We will often use blue for links,
brown or aqua for plain old emphasis, purple for sourcecode,
and a rare red for urgency.

It turns out you can simply fake an italic font in PostScript,
largely eliminating any need for them. There are two ways
to specify a PostScript font. One is to simply state the size
as an integer. The other is to use a six element array of
[ wide climb lean high xshift yshiftt ] to create your font.


Ferinstance, /Fontname findfont [10 0 2 12 0 0 ] makefont
setfont
would create a slightly compressed italic font. As
would my Gonzo Utilities equivalent of /font1 /Fontname
[10 0 2 12 0 0 ] gonzofont
.

I'm wondering what our prehistoric hanging canal explorations
can tell us about climatic reconstruction.

The evidence seems to be accumulating that ( even factoring
in our present severe drought ) things seemed wetter then.
And possibly very much so.

Ferinstance, today there is not nearly enough water in Spring
Canyon to justify any canal project. Let alone a major seven
mile long one. Hand built with stone age technology.

And one credible explanation for an early lake in the failed

there are cienega hints there as well as both up and down

MAJOR BREAKTHROUGH!

It turns out that it is ridiculously simple to edit Clearscan
glyphs when you are scanning a book for web distribution.

Completely legal and without any encrypt/decrypt hassles
as well. You can easily end up with absolutely perfect
typography and also exactly preserve fill justfification.

While a bitmap is temporalily involved, it is no worse than
the bitmap you used during your original scanning. All results
eventually end up fully stroked vector and fully searchible.

Have Acrobat 9 pro export a .TIF file for you. Open a new
version of good old Paint, converting its attributes to B/W and
then load the file. Create an optional second similar paint instance
to use as a convenient alphabet stash.

Start with the first character or the first really bad character,
depending on how much time the project warrants. Improve
this character till it is "perfect"

Typically, you will eliminate internal or external collisions, make
the feet smaller and the stems straighter
. You might also make the
character a pixel narrower or shift it a pixel or two sideways.
Mirroring or copying can dramatically improve certain characters.

IMPORTANT: If you change one instance of a character on the
page, be sure to change them all.
Otherwise, your "good" character will
just get averaged in with the bad ones.

When finished, drag the corrected TIF file back into Acrobat 9
Pro and create a new PDF file. If needed, the process can be repeated
as often as you like.

Some of the process can likely be automated, perhaps with B/W techniques
othwerwise similar to our Bitmap Typewriter.

Should a bitmap page end up the wrong size, simply correct its
horizontal and vertical resolution in its header.
One easy way
to do this is with IrfanView.

The more engineering I become involved in and the more of it
I see, the more it gets down to its fundamental definition of
a sense of the fitness of things.


The local prehistoric canals I've been exploring are so utterly
beyond incredibly brilliant that they clearly blow away any high
tech in the Gila Valley to this day. Given the available tools
and technology.

The reason you hang a canal on the edge of a steep sided mesa
is that this makes your slope independent of terrain!
Leading to
astonishing savings in energy and the amount of material that
needs moved.

One of their latest features to be pondered over are cutouts,
apparently used for flood control or mud removal.
Of the eleven
canals of over 30 miles to date, at least three seem to include
these cutout features.

Even more amazing, if the premise was made that their goal
was to totally exploity every drop of mountain stream water,
an extremely conspicuous and difficult site seemed totally
absent. That site has now been found and verified. And appears
to route Ash Creek water "up " and "over" the Mud Springs

Bajada.

We are now so ridiculously far beyond world class that terms like
"second only to Phoenix" or "second only to Tucson" can
clearly be dropped. Engineering a flatland river canal is utterly
trivial compared to mesa hanging.

Field mice are definitely needed. As are toys. Topping the toy
list is a precision MEMS altimiter and, of course, a Draganfly.

Please email me if you want to be part of the team.

One of the continuing surprises of our hanging canal
studies is how much "they" relied both on micro and
mega topographic features. In many cases, an unusual
and highly localized topo feature that is totally counterintuitive
plays a key role in making an entire canal system possible.

One obvious example is where the Deadman Canal
purposely crosses the narrowest and highest point on its
mesa, exactly where a three way switch can be best
used to route water to three wildly different drainages.


Or the several instances where a canal makes a "U" turn
and purspurposely routes itself back UP canyon, contrary
to the predominate mega terrain direction.

Or many instances where "up" is really "down" along a mesa
edge.
The wonderments continue.

October 28, 2010 deeplink respond

I'd forgotten how stunningly simple a technique called
arcto crowding can be to make fancy borders. It is
detailed in our Gonzo utilities and examples can be
found here ( Particularly ATG 59 and 72 ) and here.
( Particularly LC 45B ).

Gonzo has a routine called roundpath that rounds the
edges of any arbitrary path...

/roundpath {/rpdata exch def /rprad exch def
rpdata length 1 sub cvi /rppoints exch def rpdata
0 get rpdata 1 get moveto 2 2 rppoints 2 sub
{/rpvalue exch def 0 1 3 {rpdata exch rpvalue
add get } for rprad arcto pop pop pop pop} for rpdata
rppoints 1 sub get rpdata rppoints get lineto} def

Note that only the internal edges are rounded. The initial
and final data points close on themselves and complete the
figure.

Now for the sneaky part. If you put a box or whatever at
each corner of your figure, the arcto operator may not have
enough "room" to operatate properly.
Giving you a mind
numbing variety of special border effects.

These can be especially useful combined with the Gonzo
superstroke operator or intentionally using negative radia.

October 27, 2010 deeplink respond

The optimal grade for a prehistoric canal is often
something around two percent. Or Four feet of drop
for each 200 feet of reach.

The canal will not work at all with positive slope, and might
self destruct with stronger negative slopes.

The resolution needed is much better than GPS,
especially with low angles on the birds. And older
sport altimeters also have limited resolution.

It turns out there is a new generation of MEMS
pressure sensors that might do the job. Such as
this THREE CENTIMETER (!) one or this
NINE CENTIMETER (!) one. Prices for the
bare sensors themselves are in the $39 range.

Differential operation should be trivial, since you
would simply walk back to your starting point.

Finding suitable terrain would go a long way to deciding
exactly where the "missing" portion of a canal can
or cannot go.

October 26, 2010 deeplink respond

It would be best to replace any line art bitmaps left in
ClearScan with raw PostScript vector procs, but several
yet unsolved problems may prevent this.

Here's an alternate "bitmap improver" scheme I thunk
up that should be fairly easy to implement:

Change the bitmap from B/W to some color mode. I'd
likely stay with full RGB because of our previous tools
and experience in this area.

Get in good old Paint and trace everything you want to
to keep in re
d. Make your image much larger than you
need and stash an ongoing library of useful shapes and
lettering where they can be cut and paseted into position.

Then write some simple raw PostScript code similar
to our postproc tools that scans the bitmap one pixel at a timt.
Replacing all red pixels with black ones and all the others
with white.
Recrop to original size and resave as B/W.

October 25, 2010 deeplink respond

Several of the prehistoric hanging canals seem to have
branches that do nothing but drop uncontrollably off a
mesa edge.

A possible credible eplanation is that these are either
storm cutouts to prevent high flood damage. Or that they
are a maintainence tool to periodically remove mud
from the main canal.


The Allen canal cutout seems associated with considerable
caliche scouring. Suggesting uncontrolled flow. Another
potential use problem is that the bottom of the caliche is
only 1400 feet away from the below-dam canal continuation
on rather unfavorable terrain.  Other uses seem unlikely.

A newly discovered cutout on the Mud Springs canal
is remarkable similar.

Type I font glyphs have long been well and freely
documented in the Type 1 Font Format. I've
written some crude PostScript code to ecrypt,
decrypt, and plaintext convert these glyphs
here and here.
Using my Gonzo Utilities.

A current project around here is finding some
way to post edit ClearScan fonts out of
Acrobat 9.
After some checking and as near
as I can tell, there seems to be additional encryption
added to these font glyphs
. Perhaps because it
would be trivially easy to steal fonts you do not
own using ClearScan.


The usual keys do not work. Nor do the new
"Passwords". I'd expect many glyphs to end with
the closepath 9 and endchar 14. Exhaustive
searches using standard Charstring encrypt
gave no useful results. I suspect they are using
a different pseudorandom sequence generator.


Here's an alternate method towards ClearScan
font editing that does not mess with any "secret"
encryption: Export as a bitmap with the same
resolution as the scanned original. Retouch
the export and use it as a new "original".


Obvious things to retouch are missed OCR
recognitions, improved kerning, and straightening
out problem letters. Often "black space collisions"
can be eliminated by making each and every letter
somewhat less wide by a pixel or two.


Do note that each and every occurance of any
sized glyphs will need replaced, so that ClearScan
will exactly "average" to your new character.


The process can be made a lot faster and a lot
less tedious by also exporting to PostScript and
extracting an absolute character position list.

Techniques similar to my Bitmap Typewriter can
then be used to automate glyph rerplacement.


Chances are that file sizes can also be significantly
reduced with these sort of stunts.


Meanwhile, if you have found a simple and legal
method of reading and modifying a ClearScan glyph,

This cover is very rare and hard to find. I do not seem to have

Found two curious "features" in Acrobat ClearScan.
I'm not sure if I am doing something wrong, if they are a
bug, or if they are an intentional crippling.

If you have the time and dollars available, spending
extra time post-processing an eBook you are uploading
for web distribution should certainly end up worthwhile.

An obvious way to improve a mangy bitmap of line art
is to replace part of all of it with raw PostScript procs.
Besides looking better, chances are the file sizes will
be ridiculously smaller as well.

Using my Gonzo procs.

But if I export PDF-->PostScript, edit, and then
import PostScript ---> PDF, everything weems to behave
just fine, except the text search no longer works! It
is as if the links between the ClearScan glyphs and
their "real" alphabet characters have vanished without
a trace.

Retouching a bitmap might seem best done before any
ClearScan or OCR. And a strong case can be made to
scan into Paint rather than Acrobat 9 because of this.
But if there is any deskew needed at all in the ClearScan
process, permanant "wrinkles" will end up built up into
your bitmaps. Ot they will simply "lean".

I seem to be having problems with the obvious route of
PDF-->Bitmap, edit, then Bitmap-->PDF in that the sizes
often may end wildly different in the process. The
choices seem to end up too big to process or too ugly
to use.

Some more ancient history that came up on our

determined by the INNERMOST conductor or
conductors.

This is no problem on phone or phono jacks.
Or on power line cords. The one that usually
Causes the most confusion is a BNC connector.
Female BNC jacks normally panel mount. Male plugs
normally terminate a cable.

Even more subtle is the type F cable connector.
The inner coaxial cable wire serves as the male

The weekend saw many new canal discoveries.
Which, as usual, created more questions than
they resolved.


Many deep cuts were found in the lower Marijilda
area. Which added strong credence and credibility
towards the Culibra Cut in the Allen Canal
being in fact prehistoric.


The mid portion of the Allen Canal was extended
nearly to the north mesa edge. But it raised a distinct
possibility that the upper and lower reaches are
in fact two different canals.


One question is whether the Allen Resevoir received
most of its obviously high inflow from the upper
Allen canal or from once large but now defunct springs.
The watershed is simply too small and runoff free to
offer other obvious alternatives.

Meanwhile, the upper Allen canal could in fact
end up as the missing source for Jernigan Canal
water. But link evidence to date is sorely lacking,
owing partially to sheet flood damage.

If these two canals are distinct, we might
rename the upper Allen Canal as Spring Canyon
Canal
.

As we've seen, the "find OCS Suspects" selection
does not work in Actobat 9 Clearscan, and it is not
obvious whether it is going to work in newly amnnounced
Acrobat X Pro.

Here are four different routes to find out which text is
nice looking and compact and searchible, and which
remain sloppy unsearchible bitmaps...

RETOUCH METHOD -- Select Tools-->
Advanced Editing-->Touchup Text. Then
mouseover all available text. Solid blue
words will be both smooth and searchible.
White letters are still bitmaps. Words with
white stripes are smooth but not yet serchible
as a single word.

RESIZE FONTS METHOD -- Select Tools-->
advanced editing-->Touchup Text. Then
mouseover all available text. As above.
Then use
Properties to switch to a one point
type size. OCR candidates will remain in their
original positions, small converted fonts
will move.

MAGNIFY METHOD -- Select extreme
magnification and then mouse scan the full
page. Rounded but slightly erratic characters
are compact and searchible. Crude bitmaps
remain just that and likely need fixed.

POSTSCRIPT METHOD -- Export PDF as
PostScript and view in an editor or word
processor. Most smaller bitmaps using the
sepimg operator will be text that still needs
repaired.

The latest buzzword scam de Jour seems to be "Energy
Harvesting"
. And piezoelectricity seems to be their
favorite dead horse being rewhipped.

We looked at piezo fundamentals way back here.


There are two fundamental flaws involved: First,
piezo is an e-field machine, meaning that it has an
infinite source impedance. And thus is inherently
and intrinsically horribly inefficient as an energy
source.


Secondly, all of piezo is fundamentally a capacitor.
Meaning that it only responds to changes and only
produces an ac output
.


Which explains why virtually all piezo uses today
are below the one watt level and have negligible
efficiency
. They also self-destruct if their max
Curie Point temperature limit ( comparable to very
hot water )  is exceeded.


Yet another problem with most energy harvesting scams
is their duty cycle. There is no way in hell thaat cars
running over a sensor can generate useful energy
.

Power yes, energy no.

Too bad nobody knows the difference.

I've been making only limited progress in a goal of
easily editing Acrobat 9 CearScan OCR pages
to further improve them while remastering a book
for web delivery.

There are hints that Adobe has once again gotten
snotty about attempting to protect font glyph paths.

At any rate, if you export a ClearScan .PDF file to
raw PostScript, you can easily read and adjust parts of
it using an ordinary text editor
. It starts out with bunches
of working routines. Then it outputs one bitmap at a time
of amy images it was unable to recognize. Each bitmap
is preceeded by its own clipping interval. And may be
overwritten by OCR recognized text.

You can simply write over or replace these images with
these techniques. Just enter any "paste over" code
before your showpage.
Then redistill. Files can optionally
be shortened by eliminating any images you are going
to overwrite anyway. Many images can be dramatically
shortened by replacing them with "raw" PostScript code.


Following the images are the new fonts, created by
averageing out the recognized shapes of the originals.
This is amazingly powerful and downright brilliant,
especially at preserving fill justification. But some
of the fonts remain hokey owing to limited samples
of limited resolution.


Easy and simple font editing sure would be nice.

For any given font, a list of glyphs is provided. These
glyphs are then placed and spaced as needed to build
up composite text messages
.

However, so far I have been unable to decrypt the
glyphs.
The detailed documentation for eexec or
charstring does not seem to work. Neither does directly
using their defined password.

Please email me if you know what I am missing here.

October 13, 2010 deeplink respond

Some of what I thought was ancient history:

When Adobe first came out with their font
technology, they introduced a bizarre eexec
encryption scheme. Which they thought was
absolutely unbreakable and bulletproof.


I think I was among the first to discover that
eexec had a fatal flaw that any reasonably
patient seventh grader could sight read:


All you had to do is insert an extra character
and the PostScript error reporter would tell
you what was on the stack and what your
"spelling error" was
. With patience, you
could un-eexec just about anything.

And, thanks to the PostScript stack, you
could jump ahead dozens of characters at
any time.

Especially fonts. It was sort of like a safe
combination lock telling you "Uh, try two clicks
to the left".


Adobe long ago decided to publish the
eexec secret encryption in their free Type 1
font Format
text.


While normally done with C language routines,
with two sneaky tricks, you can easily encrypt
and decrypt "regular" eexec in raw PostScript.


PostScript has no explicity defined 16-bit integers
But you can force these with a 65536 mod. And the
high byte can be extracted by a 256 idiv .

One step in either the encrypt or decrypt requires
multiplying a 16-bit word by 52845. Doing so
may exceed the PostScript integer limit of 2^31-1

Fortunately, 52845 can be factored into 10569*5.
Simply multiply by 10569, do a 65536 mod, then
multiply again by 5
. Perhaps like this...

/rstart 4330 store
/c1 52845 store
/c1f1 10569 store
/c1f2 5 store
/c2 22719 store

/decryptcharstring {/r rstart store
{dup /curinchar exch store r 256 idiv xor
buildoutputhexstring  % details omitted

/r curinchar r add cvi 65536 mod c1f1 mul
cvi 65536 mod c1f2 mul cvi 65536 mod
c2 add cvi 65536 mod store
} forall }store

While this does the format book examples beautifully,
I can't yet seem to get it to work on ClearScan glyphs. I
am not sure if I have a mistake here or if Adobe is
once again being snotty about encryption.

A dilemma: Acrobat 9 Clearscan does its OCR by far
the best with a black and white scan. But this makes
halftones dark and murky at best. Halftones prefer
a grayscale scan instead.


A workaround is to rescan the halftones as grays
and then paste them into the final PDF using these
techniques
. And overlaying any bad halftones.

It is always difficult to web remaster decent
halftones.
But there are some tricks you can try to bring them
up from "mesmerizingly awful" to "barely acceptable...

Seek the best alternate source of halftones.
If possible, scan as grayscale and repaste.

Color tints may help. Knock out backgrounds
to white. Untilt to architect's perspective if
applicable.


Outline edges gently with thin grays or blacks.
"Chase" details along their length for
consistency. Make surfaces more uniform.

"Average out" areas. Eliminate any shadows
that are unneeded or murky.

Make sure scans are horizontal! Deskewing
does bad things to halftones.

Try lightening image. Somewhere between
murky dark and washed out gray.

Make open holes white. Use repitition to
make pins or legs more consistent.

Symmetry via mirroring or flipping can
mreplicate the best part overall.

Always try to do your own scans, rather
than relying on others. 600 DPI whenever
reasonable or possible.

Use raw PostScript and my Gonzo Utilities
for enhancement.

Preserve legality and provenance for
anything of historical context.

Replace true circles where needed.
Add extra white or black dots to
darken or lighten.

Make the worst the best. If all else
fails, divert attention elsewhere.

Take half and leave half on the worst
of the corrections.

Well, I wouldn't exactly call it progress, but I did
make a bunch of lateral arabesques in my quest to find
a simple and easy way to edit Acrobat 9 fonts.

The ClearScan in Acrobat 9 is utterly amazing
in its ability to scan pre-computer books and
greatly improve their fonts while fully preserving
fill justification (!)
. Espeically if destructively page
scanned at 600 DPI or higher and with very careful
and utterly flat page alignment.

Per this "still needs improved" example.

But the final fonts still can look rather ratty,
since they are based on an average of ( sometimes )
only a few slooppy samples. It sure would be nice
to reach in and "retouch" or "adjust" all these
fonts to greatly improve them.

So far, I've found five rather gruesome and painful
approaches to the problem...

Export to a TIFF file, repaste all of
the characters in Paint, and re-OCR
with ClearScan.

Export to a TIFF file, repair and
collect the characters using Paint
into your own new alternate font and
selectively replace characters using
the well hidden Properties section of the
TouchUpText tool.

Export to PostScript, read in a text
editor, and modify the font glyphs
as needed. Then redistill. The only
tiny problem here is that the glyphs,
while easily read, are Charstring
encoded. Per these details. Some
simple raw PostScript encrypt/decript
code should be possible.

Snoop around in the Acrobat 9 SDK
to see what can be built up as a custom
plugin. This takes C-language skills.

See if the free Linux based Font Forge can
be understood and adapted.

Please emai me if you find any simpler or easier
to use Acrobat 9 font editing alternatives. Meanwhile,
I'll try to work up a raw PostScript Charstring
encoder/decoder.

It sure would be nice if you could press a magic button
and get a list of all available fonts for your machine,

and press a second one to generate a font sample
catalog of what you have immediately usable.

There seems to be a way to do this in Acrobat 9, but
as near as I can tell so far, the process is extremely
user hostile.

Create a page from OCR using ClearScan. Then
select Tools --> Advanced Editing --> Touchup
Text
. Then select any block of text. Then right
click on Properties. Then Text. Then scroll down.

Presto. A complete list of every font in every
directory that you preplaced in Distiller under
Font Locations
.

The only tiny problem is they seem to want you to
"look but don't touch". Click anywhere else on
screen and Poof gone. Even a screen grabber gives
the wrong answer. No obvious copy and paste.

Hint: Fonts with hyphens in them are likely to be
PostScript. Those with commas are apparently
Truetype. The rule, of course, is to NEVER use a
Truetype font!

The only w
ays I have found so far to extract this list
in machine readable form
are extremely gruesome.

Such as memorizing them one or two at a time and
hand entering them to Wordpad. Or using Cunieform
and clay tablet to make a list by hand. Or typing them
into a laptop or a second computer.

I would think the Acrobat SDK should let you build a
plug in that you can C-Compile to provide this handy
feature. Or possibly I am missing something here.


Obviously, this is an Acrobat feature that certainly
should be provided.

After further testing, there is an alternative that
should work but doesn't: The Acrobat Typewriter tool
also gives you a list of fonts that are slightly easier
to extract. But they only give you Windows XP fonts
and clearly omit any fonts in Adobe directories!


Ferinstance, the Stone font has been installed in my
machine, but the Typewriter feature misses it totally.

This surely is a mistake or a leftover from earlier
versions. For no way would Adobe intentionally
leave their own fonts out in favor of Truetype.

of it should go up in a few hours, and a few days for

The results turned out surprisingly good for a pre
word processing book.
We scanned to Paint at 600 DPI
and then used Adobe's ClearScan for conversion. The
intermediate Paint step gave us flexibility for retouch
and whatever. At 600 DPI, ClearScan performance is
superb, leaving us with 99 percent or better searchibility.

This low budget approach gives us file sizes of 30K per
page, and figures that, while not as good as can be done,
are fully legible and reasonably pleastant to view. The
halftones turned out reasonably viewable and not
overly murky.

There is a deskew feature in Acrobat 9 that is quite
good at realigning text. But it has some possible
side effects
that can cause problems.

Ferinstance, deskewing can make murky halftones
even darker and even worse
.

If you scan to Paint instead of Acrobat 9
( usually a VERY good idea ), any repaired
image artwork may climb or lean on you
after
deskewing or have "Hershey Bar" chinks
in what are supposed to be horizontal or
vertical lines.

Finally, if you happen to have a black or color border
such as the last cover of our RTL Cookbook, the
deskewing may add ugly slanty white lines.

The rule is to make your scan as accurately aligned
as possible so that Acrobat 9 does not do anything
at all in its deskew pass
. Sadly, the finest rotation in
ImageView32 is limited to one degree
increments,
and thus not quite good enough to be useful here.

Also, any image retouching is best done as a second
pass AFTER deskewing
. This can be done by exporting
as TIFF, reworking in Paint, and re-OCRing using
ClearScan.

Managed to get some very meager but apparently
accurate info on the Allen Resevoir
. Which suggests
to me an utterly fascinating posible relationship between
it and the ( presumed ) prehistoric Allen Canal.


Many thanks to Nicole Spence Gibson and
Michael Johnson of the Arizona Department of
Water Resources
for their valuable input.

First the apparent facts:

The dam was built by the Soil Conservation Service in
the 1930's using labor from the PWA and possibly
the CCC.  This was part of the "Gila Project".

In 1948, the overflow pipe became clogged and
nobody bothered to fix it. The dam failed spectacularly
twenty years later in the late 1960's after a heavy storm
overflowed the emergency spillway .


The local rancher/farmer involved was Geral Claridge.

It is not clear why the resevoir was named for a
different local historical clan. Use seemed to be
mostly as a large cattle tank and for recreation,
especially duck hunting. Plus flood control.

No modern irrigation control structures seem
associated with the dam.


The dam held quite a bit of water most of the time,
and even unlikely "water sking" was mentioned
as a common use. Curiously, the watershed for
the Allen Resevoir is quite dry and quite small,

being only a few square miles at most.
There
are no obvious springs or access to Mount Graham
snowmelt or runoff. Heavy monsoon storms would
be limited to a week or two in July.


Followed by my rank speculations:

To me, the
obvious cause of the dam's demise was
neglecting to clean the overflow pipe for twenty years.

The investigation of the failure appears perfunctory
and cursory at best. Specific immediate causes
of the failure appears to be poorly consolidated
materials and improper moisture control during
the dam construction.

Plus, just possibly, a very proud gopher.


To me, the ONLY credible water source for such a
large resevoir would have been cleaning out and
reusing the prehistoric Allen Canal!
As sourced
from a Spring Canyon perennial reach.


The canal itself seems to have been completly covered
by the western abutment of the dam.
Without any
attempt at piping, control, or preserving flow in any
manner. Obliterated at a level significantly above
the lake bottom.

A careful study of the canal immediately above
the dam might resolve some of these issues.
This area is fairly difficult to get to.

A plausible explanation for the name disparity is
that a pioneer member of the Allen clan diverted
an "old ditch" to create a duck pond or stock tank.

In the same manner that the nearby Robinson Ditch
did so to the east. Long before the dam construction.
And presumably, before the Hawk Hollow tank.

My present belief remains that the Allen Canal is
in fact prehistoric.
And that its significant cut
is in fact world class. But that stronger proof is
still clearly needed.

Uploaded a copy of my thesis to our Classic Reprints
Library. On a deep penetrating metal locator.

On one level, this was an outright scam to con Goodyear
Aerospace to pay Arizona State University to bribe Ziff
Davis to buy a story off me.
Which they all did.

The thesis defense consisted of holding the metal locator
near a blackboard rail. Where it said "beep". No further
comment was needed.

On another level, this was one of the first published practical
uses for linear integrated circuits. At the time, "real"
linear IC's were outrageously expensive and hard to use.
So we faked them by creating differential amplifiers by
biasing cheap RTL logic gates into their active region..

While a plain old TRF receiver design that only hinted at
some signal processing opportunities, it completely blew
away existing vacuum tube designs. And did work
reasonably well at finding deep pipes.

Yeah, the upload looks kinda hokey. But I wanted to
preserve the original historical context and flavor. At
the time, most thesis figures had to be done using
traditional pen-and-ink drafting.
So I faked mine mostly
using printed circuit tape and instant transfer lettering
instead.

Which is expected to reveal this is a combined SCS

Supposedly, the original drawings are available in

over the Allen Canal without any provision for access

Which reinforces my belief that the
Allen Canal is in fact prehistoric.

It IS expected that the prehistoric Allen Canal was usurped
as a water source.
This is the only feasible water supply
consistent with long term storage. Otherwise, the watershed
in only a few square miles at most. With no obvious access
to any springs, streams, or mountain runoff.

For obvious reasons, I am going to call the huge canal
cut just northwest of the resovoir Culibra.


Although the amount of dirt moved is comparable to
the Marijilda aquaduct, the sheer size of this project
demands that exceptional effort be made finding absolute
and unquestionable proof of its prehistoric origins.

A sledgehammer method of post-editing Acrobat PDF
files is this: Output to PostScript. using Acrobat 9 Pro.
Opaquely write over the problem areas. Then redistill.

This is particularly handy to retouch or replace images.

After exporting of a single page to PostScript, get into any
old editor or  word processor and find the showpage line
followed by %%Trailer.

Add lots of white space just before showpage. Then insert
your overwriting code, using either raw PostScript or
my Gonzo utilities.

If you are retouching or improving an image, first export
it as .JPG
.
Make sure this is both legal and ethical.

Our usual reminder that current versions of Acrobat do not
let you manipulate disk files unless you first run the program
by doing an Acrodist-F from the command line.


This method will result in a longer file length, and some issues
involving transparency, links, and OCR may remain.

Just got an email from a friend of some Fort Thomas residents
who have some strange rock alignments on their property. Could
these be prehisstoric canals?

Sorry to disappoint, but these are almost certainly totally worthless
CCC busywork boondoggles from the 1930's
that are almost ( but
not quite ) as bad as today's failed economic stimulus ripoffs.


These are usually piled six deep in Fort Thomas. Examples are easily
found on the Black Rock road near the old dump, or on Runway 32
of Eden International Airport. Or especially on bajadas to the North.


Just in the unlikely case the find is real, have them go to Acme Mapper,
and center the cursor on their location, do a page link, and then email
me
the result .

The usual rule is: "If it is obvious, it is CCC."

There is a fundamental mismatch every time you try to use
a CFL compact fluorescent lamp in a track lighting fixture.


Most of the light goes out the side and gets absorbed by a
usually black or dark inside portion of the shade. Leaving
you with horrible efficiency and a largely dark room. Plus
hot fixtures that can raise safety issues.

These were intended for PAR parabolic reflecting incandescent
lamps that output nearly all of their light out the front.

One workaround is to try and paint the inside of the shade a very
bright white. But PAR shaped LED's will be an obviously better
choice as their price drops.

BTW, it is a myth that CFL's are always cheaper than incandescents.
Ferinstance, a closet light will never breakeven. And a case can be
made that CFL's are only clearly cost effective when run a
minimum of four hours a day.

Yesterday's trip pretty much proved that the Allen Canal
is in fact sourced by an apparently still perennial reach of
Spring Canyon
. While there might be some possible modern
rework or maint, it remains primitive and totally free of
any concrete, rebar, or other modern constructs
.

But many questions remain. Especially a strong and thorough
proof that this structure is in fact world class stone age prehistoric.
Most evidence to date clearly supports this conjecture.

Also remaining unanswered is the relation to Hawk Hollow
Tank, Allen Resevoir, Jernigan Canal, and exactly where
this seven mile long (!) canal is in fact ultimately headed. Plus why
there are at least four different architectural construction
styles.


I'll be talking about our hanging canals in this Saturday's
Discovery Park lecture at 6:30 on September 25th.

Finally figured out how to find text problems in Adobe
ClearScan
. The obvious "Find First OCR Suspect" does
NOT work. Instead, an indirect but highly useful process
can be used.

Start with Tools > Advanced Editing > TouchUp Text Tool.
Click on the text you want to test. Then left click and drag
to highlight the converted text words. Or use Select All.

Any uncolored word has not been converted. A word with one
or more narrow white breaks in it has been converted, but will
not be searchible.
A word with a white letter background has
only been partially converted.

Alternately, you can right click and chose properties > Select Font
and then pick any available system font. Preferably one that is
obviously different in size and shape than your original.

Your result should be all of the "good" ClearScan in the new
font and the "bad" ClearScan in the original font.


With a decent initial document and enough resolution, there
should only be one or two error words per page
. Get your
bitmap back into Paint and retouch whatever it was that
made ClearScan barf. Usually a subtle change in spacing,
some blackfill, a white edge retouch, improved kerning, or
substituting a known  good character will work.

Then redo your ClearScan OCR text recognition. If you have
too many errors per page, you will have to rethink your
original document or its scan resolution.


Even with attempted repairs, you may not be able to get
100% of your words searchible. Espeially if the text sample
is too short. Usually it is best to let a few slip by. But you
definitely should get all words readible.


This technique also should let you replace with a "perfect"
font. Some experimenting with font sizes will be needed,
and fill justification will likely not work very well.

================================================

PREHISTORIC "HANGING CANALS" SUBJECT OF NEXT
SATURDAY'S DISCOVERY PARK FREE LECTURE

Some recent archaeological discoveries have revealed an astonishing
series of prehistoric canals just South of the Safford area. These
mountain stream fed canals have the remarkable property that
portions are literally "hung" along the steep edges of remnant
Quatranary bajada mesas. Some as much as ninety feet above
their valley floor.

At least seven hanging canal systems are known. Their total
explored length now exceeds eighteen miles. Other amazing
features of these canals are that some include above-grade
aquaduct portions. Others provide for elaborate switching to
route water between different drainages. And most include
a "breakaway" feature that makes flood repair fast and simple.

The stone age technology involved seems well beyond world-class.
Reaches of at least some of these canals still flow to this day.

Some engineering details on these hanging canals will be
presented as a talk in the continuing fall Discovery Park lecture
series by local author Don Lancaster. This free presentation will
begin at 6:30 PM on Saturday, September 25th in the Discovery
Park Jupiter Room.

The lecture may be previewed at http://www.tinaja.com/glib/hangcan1.pdf
and at http://www.tinaja.com/glib/hangshow.pdf

Everyone is invited to these family-oriented talks. Students of all
ages may qualify for extra credit. 20 inch telescope viewing and
free planetary flight simulator rides may also be available. Discovery
Park is located near the corner of Discovery Park Blvd. ( aka 32nd
street ) and 20th Avenue in Safford, AZ.

A very interesting low cost book scanner can be found here.
And bunches more on lower cost DIY scanners here.

And info on the Scan Tailor here.

Scanning remains best if you can destroy the book or if
your document is already on separate pages. The Clearscan
OCR in Acrob
at 9 is exceptionally useful during the
conversion process.

Othewise, a  high resolution digital camera can sometimes
( with care ) be a better choice.

How high is high? A true one megapixel camera imaging a
flat and correct 10x10 inch B/W area would give 100 DPI resolution.
For 200 DPI, you would need four megapixels and for 300 DPI
you'll need nine megapixels. Or 16 Megapixels for 400 DPI and
you can clearly forget about 500 DPI.


But color processing involves a resolution robbing Bayer Filter.

And other factors besides raw resolution may determine the
camera's image quality. Bottom line: Use 12 megapixels miniumum
and try several cameras to see what works for you.

Acme Mapper can sometimes be a useful substitute for
a GPS receiver. If you do not have differential GPS
available, it can even give you more accuracy!


Even at its "rural" resolution, you are looking at 200 feet
in 70 pixels, or about three feet per pixel. At the "city"
resolution, you have 20 feet in 70 pixels, or well less
than a foot. But the actual data is usually somewhat worse.

The cross in the middle of your image will give you its
GPS location.
These are easily extracted and emailed.

You can also flag various GPS locations. But note that
there is apparently a bug in which the letter sequence
of the flags may change unexpectedly

Properly converting an older printed document from a
thick bound book or a weak Xerox copy is a lot more
complicated than it seems. I'm in the process of
web formatting my thesis and most of my earlier
books and found some rude surprises along the way.

Simply scanning will not hack it. After scanning, you
first should go through some background improvement
and other retouching. After that, you will need some
elaborate OCR. This can make your file sizes much
smaller and allows at least partial full text searching.

Getting into Acrobat PDF format also, of course,
lets you magnify figures, have text read aloud,
combines pages into full documents, and provides
reformatting and other benefits.


Adobe has a feature in Acrobat 9 called Clearscan.
Given a good enough and a high resolution enough
copy, it is utterly amazing what it can do. On the
other hand, it still seems buggy and a still work in
progress.

Clearscan attempts to average out all the character
defects and creates a new font that looks significantly
better.
But I cannot seem to get the Find First OCR
Subject "missed stuff" to work at all.

It also would be super nice to be able to edit your final
font and improve it. Particularly if an old typewriter
was weak in dotting "i" characters. Being able to
globally mark backgrounds would also be super
useful to get rid of Xerox speckle and artifacts.

A minimum of 600 DPI resolution is recommended for
scanning. Using plain old Paint to get from document
to initial bitmap seems to work well. Particularly
since you can easily improve backgrounds before
continuing.
And even attempt to repair the
worst of the lettering.


Needless to say, a squeky clean scanner is a must!

One hint, on Paint at 600 DPI, you cannot view the
entire page at once and may miss some background
problems. Put a separate copy into Imageviewer32 and
adjust its size to whatever is convenient.

It is a good idea to give Acrobat 9 several similar
pages at once to work with. This way, it has a
reasonable number of character samples to use.

You can follow the progress of the thesis project here.

I see something enormously distressing taking place on
the web. Completely ignored and of profound significance:

Only history that has a champion survives the web!

Ferinstance, you can easily find the rules for Mad
Magazine's 43 Man Squamish from their June 1965
issue. .

But Sallen and Key's crucial 1955 paper defining the entire
world of Active Filters is not freely available anywhere!
Heathkit schematics are readily available from dozens
of web sources, while details on automotive diagnostic
interfaces are few and far between.

In other words, trivialities survive while essential defining
documents go begging.


One obvious solution: MANDATE that all scientific papers
older than three years have free web access from multiple
sources!
It is way past time to stake the gatekeepers to an
anthill.


Note that most published scientific and quite a few technical
documents are paid for with your tax dollars. YOU own
these and should have every right to freely access them.


A second obvious solution: Restrict copyright to 36 months
renewable once upon careful review to an individual, and
to 18 months nonrenewable to any corporation or heir. With
manditory free web conversion afterwards.

Yeah, I am trying to not be part of the problem. Many
classic reprints appear here, with others in the works.

The National Inventory of Dams did approve my password

What is really amazing is that there is apparently ZERO
overlap in county, state, and national dam directories.

I am mildly curious: Even with "oops, it broke", how do you lose
a 500 foot long, 30 foot high dam with a lake behind it?

And hide every written document on it anyplace ever?

And instill in the locals not the slightest clue nor the least
interest that it exists? Even when you can almost throw a rock

We get lots of requests for efficiently drawing a smooth
curve through multiple dots.

This is amazingly more complicated than it seems. Especially
when the dot positions are beyond the capability of the math
used, when continuity with other dot groups is needed, when
the dots represent fuzzy data, or when fast and efficient
computation is required.

I thought we might list a few resources here, and possibly
eventually make a GuruGram out of it.

A key doncument on solving the problem with cubic splines
can be found here. This is not easy reading.


A cubic spline intro tutorial can be found here.

We have long had some curvetracing routines in our Gonzo
PostScript utilities
. These were based on using weak and
inefficient splines, one per dot pair. They were rather
painful and tedious to use in that you had to enter a X value,
a Y value and a slope at each point.

It occurred to me that you could sometimes fake the
slope by using the previous point, the present point,
and the next point to temporarily draw a circle. The
slope at the present point is often a good fit. Some
more details of this improvement appear here.


It is almost always possible to draw a cubic spline
through four points, as shown here. Since there
are usually an infinite number of splines that can
do this, an optimization process can be used. This
is often the shortest spline as well.

Things get considrably uglier when trying to fit
fuzzy data with lots of points to a single cubic
spline. Some details are here on a least squares
optimization routine. Some of the points may be
missed per the details here.


Details on finding the minimum distance from a
point to a cubic spline appear here.


And on the length of a cubic spline here.

And on subdividing a cubic spline here.

You can always draw a power series through n
data points, but the behavior between  points can
end up surprising, and certain limits ( such as
overshooting 1 or 0 ) may arise. Per the details
you'll find here.


Many of the approaches may need solution of
nxn linear equations. Per these details and
these complications.

I seem to be having an outrageously difficult time finding
anything at all about Allen Reservoir, a spectacularly failed
and quite large dirt dam two miles southwest of Thatcher.

Yeah, there's lots of web sites that lavishly praise the fishing
at a spot that has been bone dry for decades. And dozens
more will give you the exact GPS locations.

The geneologcal historian for the Allen clan never heard of
who built it or why. The historical society president is in the
hospital. The SCS ignores completly my local and national
emails. And the national dam directory has locked me out
because they apparently think I am a terrorist intending to
further destroy an already completely destroyed dam.

All I am really looking for is proof that a canal the dam
completely obliterated and ran over at its western abutment
is in fact prehistoric
. The CCC does not seem to be involved
as there is waay too much dirt and not the slightest trace of
fancy rockwork.

There is a thirty foot hole in the dam, likely caused by a
very proud gopher. I suspect the owners do not want to
own up to it, because they apparently destroyed a perfectly
good seasonal duck pond in one of the usual government
boondoggles.

I suspect the houseboat franchise may be available.

Leave it to the Military to point out to me via email
that a Epiphany is usually overwhelmingly positive,
while a "Holy Shit Momement" can be either very bad
or very good.

Some personal examples...

Way back when I was first developing our
curvetracing routines, I decided to use
Mickey Mouse as a subject. Halfway
in the development process, about 2:15
AM, I entered ONE wrong coordinate.
And Mickey instantly got an appropriate
sized and positioned erection! Sorry, but
for obvious reasons, code ( with or without )
is not available.


I witnessed a tanker rollover in Phoenix
that created the usual movie-style fifty
foot fireball. In the length of time it took
to say "Holy Shit", the fireball blew itself
out, leaving the rest of the zillion gallons
of diesel fuel below its flashpoint.


For decades I had been finding tantalizing
hints that Magic Sinewaves were in fact
real. Sure enough, at 3:15 AM a waveform
popped up with all low harmonics precisely
zero. The Holy Grail was found!


Finding a continuance of the prehistoric Allen
Canal
in an unexpected place, superb
preservation, and world class size was a
recent example.


But the most recent "Holy Shit Moment" was
realizing exactly WHY the prehistoric obsession with
hanging canals halfway up the sides of mesas:
This made the slope INDEPENDENT of the terrain!
And, factoring in the available technology, makes
the LBT look like a tinkertoy set.

The Central Arizona Grotto of the NSS is having a fiftieth (!)
anniversity bash. Due to a groundswill of popular demand,
I was asked for some comments. Which I'll repeat here...

==================================

I guess Bee and I have been long term CAG members since
1967 or so. We were attracted to the Grotto by an Arizona
Highways
story. We had done some minor caving in Bear Cave
and elsewhere in Pennsylvania and wanted to know more about
Arizona's Pivot Rock cave.

I was never a gonzo supercaver. That award surely should go first
and foremost to Jerry Hassemer. Or at least to his dog Suzy.
With such illuminaries as Ron Bridgemon, Pete Delaney,
Bob Buecher, Dwight Hoxie, Tom Strong, and Lang Brod
( and dozens of others ) certainly in the running.

Over the years, I was often the grotto vice president and edited
the Cave Crawler's Gazette newsletter for three years. In those
days, properly doing a newsletter involved an awesome amount
of time, effort, and cost. I still hope to get these newsletters up
on the archive of my website at http://www.tinaja.com . A classic
cover involved the DISMAL I, a "Diet Smith" magnetic car
levitator that really was Pete Delaney and a pair of crutches
standing in a garbage can. Overlayed on an impressive cliff. Such
photo edits were a lot harder before PhotoShop.

We often hosted grotto meetings, sometimes involving a "who
turned out the lights?" drunk Saint Bernard. One of the grotto
meetings was literally sixty five feet in the air on the Gentry
lookout tower near Heber.

While we regularly attended CAG events even after moving first
to Parker and then to Thatcher, my primary "loyalty" was always
to the ARA. As I felt that outreach from the cave community was
(and very much still remains) a crucial issue. We probably hosted
more ARA paper regionals than anyone else, mostly at EAC or TFD.

My biggest Arizona cave "find" was the extension Jerry Hassemer
and I made to Dum Ditty cave. I remain convinced major wet passage
remains beyond its present terminal crawlway.

Finding virgin passage remains one of the ultimate highs of the
caving experience. Out of state, I was involved in finding thousands
of feet of virgin passage in California's Lilburn Cave. But this was
largely a trivial task at the time. Bee and I also did some fuzzy
elephant research in Natural Trap cave in Wyoming as part of a
scientific expedition. Where I managed to blow up a cave pack
full of spent carbide. We also played a negligibly minor role in
Kartchner development.

My focus was often on the Redlake area. We did quite a bit of
pumping both in Redmond and Bear Sprinhgs. I am convinced
there is a lot of potential remaining in Bear Springs and in Hot
Dog pit. There still is a largely unchecked lead half a mile
northeast and above Hot Dog in a slanty entrance that just might
lead to big time new cave. The crucial issue of the area remains
Pishiboro heading South to the Frog Pond with Columbine's
water source remaining an enigma. Bear Springs may remain
the key to the puzzle.

One major effort for little return was the search for Mescal Pit.
Dozens of trips and one regional were made to the Sombrero Butte
area, eventually finding a minor 95 foot pit in precambrian limestore.
A second unfound "rocks roll forever" pit, tentatively named
"Strawberry Awful", is rumored a mile to the northwest. You can't
get there from here. This did eventually lead to the exploration and
mapping of El Diablo. Which remains in the most spectacular
scenery in Arizona and involves rather challenging hiking.

I was also overly enameled of El Capitan canyon. While only
"almost" a caving experience, it remains a "must visit" for any
caver. The "next" El Capitan Canyon is likely to be San Carlos Falls.

There are many long term legends of Arizona caving. But four of the
more persistent are the "hall tree", "Bee and the flamethrower",
the "watermelon caper" and the "jawbone of the ass". Seems Greg
Lazear had a hall tree he no longer wanted, so he hid it in a remote
and secret Arizona cave. Other cavers found it and rehid it elsewhere.
Over and over and over again. Simply referring it as "it" and carefully
never mentioning what it was or its history. It probably has been in more
caves than anybody and probably recirculates to this day.

Bee was in Peppersauce Cave once and kept asking "Is my lamp lit?"
At the time her carbide light was putting out a foot long flame. Turns
out that caving with prescription sunglasses on can be suboptimal.

Students of Dave Thayer knew he was planning a Grand Canyon river
trip the next week, so they backpacked and preburied a watermelon,
pineapple, crutons, a silver fingerbowl, and, of course, beer in the sand.
Only to lose track of time and having to sleep on the Tonto Rim in garbage
bags on the way back up. One participant who was brand new to caving did
not notice anything out of the ordinary when they handed him a watermelon
and asked him to backpack it. The prank ended up an overwhelming success.

A jawbone of an ass was found at the bottom of the Grand Canyon and
placed in the pack of a known volatile caver. Who was furious about finding it.
After SIX TIMES of refinding it in his pack, he violently threw it over the
redwall. Sure enough, it ended up back in his pack and it made it all the way
to the rim. Requiring heroic physical effort on the prankee.

This has been an unusual year for desert wildflowers locally.
Some say the best in forty years.

Fall flowers are often relatively rare and minor. But we now
have a spectacular bloom of something. Possibly Isocoma
Tenuisceta
. Who their friends call burroweed, shrine jimmyweed,
or burrow goldenweed.

What is mind boggling is this: In two smaller areas, a very
conservative calculation leads to ONE HUNDRED BILLION
(with a "B" !) blooms.

They have been around for several weeks now.

This borders on "several" or "an adequate supply".

The latest report on pv solar panel prices is found here. Where we
see pricing holding steady at $3.50 per peak panel watt for the summer.


This pricing level, of course, GUARANTEES that pv panels today
remain a humongous gasoline destroying net energy sink
. This price
is SEVEN times that required for pv panels to become an utterly

pointless "paint it green" transfer scam. AKA the "holy grail"
of one dollar per fully burdened installed system watt.

And are NOT in any manner renewable nor sustainable.

For net energy breakeven at ten cents per kilowatt hour amortization,
and genuinely becoming a useful energy source, the price has to drop
by a factor of FOURTEEN to twenty five cents per peak panel watt.

Found another small chunk of the Allen Canal. While
there still are some "minor" gaps of 15,000 feet or
so, evidence is finally preponderating that this in fact
is one entity
. And quite likely is prehistoric.

Running over TEN KILOMETERS (!) from Spring Creek
to the Jernigan site. The middle half is astonishingly large.
But mostly in "badlands" style terrain that is fairly easy to
dig or scrape. As before, the engineering is astounding.

Age hints are accumulating. There are full size barrel
cacti growing in the wind blown fill in the canal center.
A spectacularly failed flood control dam ran right over
the canal without any regard to access. As did an
apparent CCC Hawk Hollow Tank project. Apparently
very old fencing slices through twice without concern. As
does a major and historic dirt road.

There flat out were not enough historic pioneers to take
on a task like this. And they certainly would have mentioned
it in their carefully kept famiily records. While the prehistoric
population is estimated to be near the present of 30,000.

And it would be much easier for an early historic rancher or
farmer to"dig out an old ditch" than it would to engineer a
world class project from scratch in their spare time.


Proof of age and continuity remains elusive, but should be
forthcoming

any scientific discovery, it raises more questions than it

IF this is a continuance of the prehistoric Allen canal, it
is huge, has a different architecture, and appears well east
of where it was expected. But it IS a hanging canal.

If historic, CCC, or modern, it makes no sense at all

As we have seen here, a key major advance in
publishing in general has been to typeset first and
edit second
. Rather than the other way around.


I very strongly feel that the solution to the current
scholarly publishing debacle is that we should always
publish first and peer review second
. And NEVER the
other way around
.

Such as the Wesrch Model.

If something is wrong with what you said, you fix it.

Instead of the present system that involves years of
delays, gatekeeper greed, and journals so expensive
and so elusive that even most libraries cannot afford
a subscription.

ALL scholarly papers over three years old should be
freely and instantly web available from multiple sources.
Without any access restrictions whatsoever.


Failure to do this will result in traditional scholarly
endeavors pricing and otherwise restricting themselves
out of the market. And out of business.

Fortunately, there are moves underfoot to guarantee
government funded research to become freely available
after a reasonable quarantine delay.

The old peer review model no longer works. Live with it.

Revised and updated our Prehistoric hanging Canals of the
Safford Basin.

The source and sink of the Allen Canal is taking form but
remains uncertain. It appears a CCC "steal the plans"
rebuild/adaption of Hawk Hollow Tank straddles the original
prehistoric canal. About 12,500 feet remain to be visited.

The hanging part is sort of vague in that its route is less
steep than the original canyon bottom. It is, however, very
well defined.
And accomplishes the same tasks as a true
hanging canal route would
.

Turns out that nearly all of the hanging canals are newly threatened
by a proposed realignment of US 70 well south of its present
urban route.
A major alignment study appears on the web, but
I cannot refind it. Apparently it was a scanned copy that does not
allow search terms. Prehistoric considerations are not even

These are world class archaeologcal features that very few

There is a terrible, terrible Google Analytics bug that is

The symptom is that any visitor sees an unwanted and certainly

least, is maddengly infuriating.


There are apparently three factors that cause the bug:
(1) A website host failing to place the analytics link at
the VERY END of their website code. (2) Google response
being slow and creating a 403; and (3) Firefox gagging on
a Google 403.


Naturally, everybody will blame everybody else. Meanwhile,
it is your website that gets trashed.

I may have found a credible explanation for why the prehistoric
canals
were all purposely hung on the edges of steep sided
mesas:

Doing so gives precise control of canal slope INDEPENDENT of
terrain!!!!!
And minimizes cuts and fills.

Which would ( and probably does ) represent utterly brilliant
engineering.


The gently sloping top of a mesa makes a suitable canal
surface, while the steep sides let you precisely control the
initial slope. Taken together, these might form an unbeatable
combination for transporting water long distances.

Apparently they bought a "large" from the canal

It also does not hang nearly as much, ending up "only"
twenty feet or so up in the air.
Total length is about
a quarter mile and it is used as a "local" to link two sets

Two interesting stunts could improve video editing.
We might call these scripting the script and editing the
editor.

Naturally, you should save your edits often. You should
also do as much with the edits as possible, avoiding any
and all reuse of MP4. For edits of an edit can lead to
blotchy titles, poor sound, and other problems.

Yes, generation loss is much, much less with digital
video. But it is not gone completely.

At any rate, a plain old Wordpad reminder script can
keep track of which saved version does what. This is
particularly useful for preserving start, end, and length
points for latter clip inserts and upgrades.

Thus scripting the script.

The .vpj files created by the VideoPad editor are simple
plaintext lists of clips used, time sequence, and sound
mods.
These are surprisingly short, typically only a
few K long. They are easily read and modified with
Wordpad or any other text editor.

Hand modifying a .vpj file could have lots of interesting
uses. Ferinstance in changing a video clip name for
an update. Or upgrading a .JPG to a true .BMP. Or
changing a directory for a new but similar project.

Thus editing the editor.

I'll eventually try to work up a GuruGram on all this.
Other GuruGrams are listed here.

I'm having troubles proving such is so with the prehistoric hanging
canals
. At present, the Allen Canal delivered water somewhere
to an unknown location and purpose. The Jernigan Site
obviously needs a major unknown water source.

The two are 5000 feet apart with a reasonable slope between
them. But with three intermediate stream crossings. The area
is hard to access partly because of a locked gate on a dam and
is patrolled 24/7 by roving bands of Gila Monsters.

There are possible other Jernigan sources and Allen sinks.
None of these seem compelling. Sheet flooding could have
long ago complicated the picture.

Org. The initial title page of our new Intro To PostScript
video
was looking awful. And, amazingly, did not get any
better with a full bitmap rather than a .JPG still.

It turns out that MP4 files have to have at least four
frames before they can get up to speed on any change.

And your first frame may look awful if it is just sitting
there waiting for your viewer to hit the play button.

The workaround is to start with a nondescript frame of
pretty much a single color, fade into your title background,
and then fade to the actual title
.

I've been fighting a really obscure bug involving running
the Acrobat Distiller on Windows XP. Not sure if it is only
my machine, or something others can use. But here goes...


As we have seen here, Acrobat Distiller makes an
outstanding host based general purpose PostScript
interpreter.

Starting with Acrobat 8.0, Adobe has default locked out most
disk access on Distiller. Bypassing some obvious abuse
potential.


Their published workaround is to run "acrodist-f" from the
command line
. This restores full disk access to Distiller.
Unfortunately, their early docs wrongly told you that acrodist-f
disables, rather than enables access.

At any rate, acrodist-f normally works just fine for enabling
and is essential for most of my PostScript-as-language apps.

But it would stop working for me for weeks at a time but only
for certain XP users. The bug and the cure may go something
like this: The windows command line apparently will refuse
to process acrodist-f if the previous command resulted in an
error!


An apparent solution is to type HELP from the command line.
Or some other known good thing for it to do. This seems to
restore proper operation.

VHS video to online distribution...

0. Be sure you have lots of disk space available.
    Make sure any free software has been upgraded
    to allow MP4 saves and eliminate other hassles.

1. Convert the VHS tape to a computer readable
     digital format, possibly by using a dubbing
     dual VCR/DVD machine.

2. Convert to .MP4 format using Leawo or
    similar software.


3. Make sure all artwork clips end up at the
    needed final resolution. One good route
    with hires originals is to crop and reduce
    to 4X, blur strongly with Imageview32,
    reduce to 1X, and gently resharpen.

4. Edit and produce your .MP4 video using
    Videopad or a fancier program.

5. Upload to a suitable website or YouTube.
     Make sure your participant.

Here's some of the "figure improvement" techniques we are
using in our ongoing update of the Introduction to PostScript
video.

Much of the work is being done with plain old Paint and Imageview32.
Helped along by our Bitmap Typewriter.

We purposely picked the iPod resolution of 320 by 240, first because
of the challenge of getting good lowres results, and second to keep
the file sizes down. It is very important that all stills and titles have
the native resolution you are seeking
.


It is also super important to minimize any and all high frequency
info in your images
. Fail to control this, and the results will be awful.

We typically would start with a high resolution original and crop it as
tightly as possible. Also considering a pan or a double shot to show
what is needed. Some tints or color were added wherever they could
indeed add to the result.

The hires original was then reduced to FOUR TIMES the needed
final resolution. Typically this would be 1280 pixels wide or 960
pixels high. If the original was not in a 4:3 format, the critical height
or width
gets used.

Now for the sneaky part: You have to get rid of higher frequencies
or the results will look awful. Add some very significant BLUR to the
4X image!
Perhaps four or more clicks. Then reduce 4:1 to 320x240
and gently resharpen.


If the final is too narrow or two short, get into Paint and click on
Attributes
. Reset to 320x240 and recenter. Always stay in
the .BMP format till one final .JPG save.


In general, the blur-resize-sharpen dramatically makes light lines
darker and heavier
. And even eliminates many dropouts.


The 4,752 perspective bricks in the bulding proved to be a problem
and created severe Moire issues. This was gotten around by
replacing the bricks with an indinstinct lowres texture.
Taken in context,
this does not look too bad.


Should have some viewable results shortly.

Found some supporting evidence that suggests the Allen
hanging canal is in fact prehistoric. Or at least "fairly old".

In three separate places, there are large barrel cacti growing
directly in the middle of the filled canal path.
Considerable time
would likely be needed for the canal to fill, germination to take
place, and the cacti to grow to these large sizes.

It might be interesting to study the fill particles to try and see
whether they are wind or water borne. If wind based, this would
likely add considerably to the age of the last use.

It still is not clear where the canal is headed. Part of the area
to the north is largely alkali and more or less badlands. And
the one known habitation site is pretty much to the north and
west, with several drainages in between.

Total length of the canal seems to be approaching five or more
miles. Construction style and energy levels definitely seem
consistent with prehistoric. And the number of manhours
involved boggles the mind.

As does the world class engineering.

Here are some of the steps we are going through in our
making our older Intro to PostScript video available online:

The analog VHS tape first needs converted to a digital
format that is computer readable
. While there are quite
a few adaptors and systems available, the easiest is to
go with is a Magnavox combination VHS/DVD dubbing
recorder ZV427MG9 . These are available from
Walmart for just over $150.


It is super important your choice allows DVD recording
from VHS
. The magic word is "dubbing" The output
will be a computer readable DVD/R with files in the
digital MPEG2 format.


The "best" modern format for online distribution is
probably MP4. A $30 MP2 to MP4 converter
is available from Leawo and seems to work just
fine for us.


Next, a MP4 resolution has to be chosen. We decided
to go with the highly limited but popular 320x240 format
since it is iPod compatible, has small file sizes, and
gave us quite a challenge in reformatting stills and
titles.

The low resolution is not quite as bad as it sounds.
Compared to NTSC (Never the same Color) tv,
it allows wall-to-wall useful info. Because there is
no wraparound and no retrace. Plus much better
chrominance/luminance separation since there
is no longer any luminance. And, of course, no
copy-to-copy degradation.

It is super important the all stills and titles have
exactly the needed resolution!
Otherwise they will
look awful. More details in a day or two.

A video editor that is newly MP4 compatible will be
needed. We found the free Videopad editor somewhat
limited but more than useful for this current project.

The ISP provider on your website may have to make
a change or two to allow video downloading. Such
as giving .MP4 file extension permission
. And
YouTube may have length limitations.
We are not
quite there yet, but it should be only a day or two.

The sixth hanging canal is real! Haven't found the

Size is the usual meter wide by ten or twelve centimeters
deep. We can call it the Allen Canal for now. Have only
explored half a mile or so in the middle of the bajada, so
it is still  unclear where it comes from or where it goes.

Or what its ultimate purpose was.

Best present guess is that it sources somewhere near
Hawk Hollow Tank or Upper Central Wash and delivers
somewhere near Allen Reservoir. Some parts may be
barely visible on Acme Mapper. But remain unchecked.

We are in the process of converting and uploading our
original Intro to PostScript video both to the Guru's Lair
and YouTube.

Boy, things sure have changed. This was originally done
three years before the initial Video Toaster release.
Video at that time was outrageously crude and expensive.

Especially -gulp- any frame by frame editing.

We started off by finding a hungry rural video outfit that
specialized in vids of people falling off horses. The
best available cheap reasonable quality at the time was
a system called Industrial Betamax. Analog, of course.

The taping session ended up poorly promoted, so it wound
up being single camera shot with an audience of only three
people. After the shoot, we hijacked an entire community
college English class and had them pass around all the
handouts
and pretend they were interested in them.

We managed to include such advanced state-of-the-art
special features as zooms, video titling(!), awful music loops, and
special effects such as inserted still images(!). Wowie Gee!

The video house ended up losing our master tape. So, all we
had  left was a fairly mangy VHS copy to work with for the
current processing.

So, yeah it is kinda hokey. But it remains a historical record
of the early days of PostScript.
The tools and techniques
shown were utterly mind blowing revolutionary at the time.

We are trying to improve the video by shortening it to
only the PostScript Show and Tell part and redoing the
titles, stills, and possibly the horrible music. The portions
on getting started with PostScript, toner cartridge refilling,
Kroy Kolor, and binding systems may become additional
"historic record" videos if there is enough interest.

We are only halfway through the conversion process, with
everything now digital and in computer. Full details will
show up here soon when we get everything worked out.

Extending our Magic Sinewave calculators to higher
values beyond n=23 are likely to create problems with
Gauss-Jordan stability issues.

Stability is caused by coefficient blowups that eventually
can easily get far beyond the range of even 64-bit math.

One sledgehammer cure might be to go to 128-bit math.
Since only subtraction, division, and translation are needed,
the routines might not end up too ugly.

High nxn blowups are very much dependent on the column
and row positioning in the original equations. Messing with
the colums gets ugly fast, but rows can be interchanged in
any order
without changing the solutions.

A Monte Carlo approach might work. In which you shuffle
your rows several dozen to several hundred times
and then
pick one with the least coefficient buildup.

I've been exploring a different route in which you progressively
find the best next row position
. Eventually creating a list of
optimal or near optimal row sequences. You then do the
Gauss-Jordan reduction on the best choice on the list.

At any time you will have a candidate row and a column of
interest. The coefficient in the candidate row gets subtracted
from each remaining row to create a distress value. The
distress value gets normalized in the next step, sometimes
causing coefficient blowups.

A distress value of +1 or -1 will cause no coefficient blowup.
An absolute distress value less than one will cause blowups.
The smaller the distress value is, the worse the eventual blowups.
Because of the unity normalization in the next step.

It is not immediately clear what an absolute distress value greater
than one will do, but it usually should reduce blowups. Further
the odds are good that any extremely small normalized value will
get "swallowed" in its upcoming subtraction
.

The algorithm might proceed as follows: The distress value is
modified by abs dup 1 lt {1 exch div}{1.0} ifelse creating a
nastyness factor of unity or higher. The nastiness factor
is calculated for all remaining rows and least square summed
and square rooted. Creating a potential blowup index.

The process gets repeated for each candidate row and the
row with the lowest blowup index goes on the sequential
row lis
t. I should have some demo code shortly .

Got several requests for more info on color organs.
Reprints on several classic construction projects can
be found here. And good old number one here. I am
working on eventually uploading quite a few more.

But, except for rock shows and night clubs, these are pretty
much obsolete
. Since you can do so much more so much better
with a computer based display driving an HDTV.

There's also a bunch of technical issues that were never
properly solved with the previous batch of color organs...

DYNAMIC RANGE -- The dynamic range of
lamp brightness is ridiculously less than that
of most music. An automatic level control or
automatic gain control would help bunches.

As would very heavy audio compression.

LINEARITY -- Dynamic range is further
compromized by extreme nonlinearity of
most light bulbs. One cure might be table
lookup
linearity correction. In which incremental
(or log?) changes
of input level produce some equally
incremental changes in output light.

RFI -- Astonishing levels of radio frequency
interference are produced by classic color organ
systems. This can be reduced by extensive inductive
filtering on the power lines. Another and possibly
better solution is to go to reverse phase control
techniques where the light goes on at the beginning
of each power half cycle and then is turned off
in inverse proportion to the audio strength. This
demands power MOSFETS rather than SCR's
or triacs.


DISPLAY ISSUES -- Getting fully saturated colors
is tricky unless you go to lasers or LED's. Heat
management can be a problem. And the static
light positioning can easily and quickly become
boring. This is likely a fatal flaw.

AUDIO FILTERING -- Early active filters could
certainly be improved, and digital filters would be
even better. But best of all would be elaborate
computer signal processing in which each instrument
would be assigned a color
, rather that colors being
frequency specific.

I'd be happy to assist others in developing a new generation of
color organ related devices, but it is extremely unlikely that the
interest and the funding would be there.

May have made some progress on the Gauss-Jordan
stability problem. Easing this may be needed if our
Magic Sinewave Calculators are to be extended significantly
beyond their present n=23 limit. Some of which already need
a 46x46 linear equation solution.

It turns out you can interchange any two "lower" equation
rows that are not yet fully processed
. Without changing any
results. The trick is then to decide which is the "best" remaining
row to currently process.

Some of these will cause significant coefficient expansion and
others will not. Compare the present improvement candidate
against all that remain and see how bad the expansion is
. Then
select the best present candidate.

After doing a "column of interest" subtraction, a new number will
remain that will get normalized in the next step. The closer this
number is to unity, the less of a buildup problem it will create
.

You can establish a figure of merit by using abs dup 1 lt {1 exch div} if
to produce a number that is "the closer to unity, the better". You can
then do a rms summing and square rooting of all terms from the candidate
row pair to get a"term expansion" value.

You then pick the candidate row that has its lowest overall term expansion
value
. Typically, one or two candidate rows will be much lower than
the others, and will contribute the least to degrading stability.

The process can be repeated for the remaining rows. Only a few hundred
passes may be needed, because each winner gets removed from the
remaining candidate pool.

I've got some demo routines in the works.

There's a glitch in our search for the easternmost Saguaro
cactus: The latest finds do not appear to be Saguaros at all.

Instead, we have about a dozen mystery cacti that are six
feet tall, about a foot in diameter, no arms, and perfectly
vertical. The spines are sort of fishook and sort of triangular
but much smaller and not nearly as curved as most barrel
cacti. Pleating is only moderate.

Saguaros this height would usually be smaller in diameter
and have even finer straight needles.

I've never seen a fishook or a barrel cacti remotely this high.
Most would also tend to be fatter, more pleated, and pointing north.

There was a big flap in the media about some Brit who
was arrested for shilling on eBay

Since shilling is not possible on eBay, I do not understand
what the big deal was.

Firstoff, in the US, shilling is in no manner illegal. The
Uniform Commercial Code specifically allows it when
preannounced or during a distress sale. Otherwise, the
draconian remedy is that the price drops back to the
preshill level.
Nothing more.

The reason that shilling does not work on eBay are that
its two essential elements of mark demeanor feedback and
auctioneer bailout are not present. In a live auction, the
shill must carefully watch the mark and know when to quit.
A "winning" shill, of course, loses. Thus the auctioneer must
be ever vigilant with an "I'm sorry sir, I could have sworn
you had your hand up".

Further, a 100 percent defense against misguided shilling
attempts on eBay is to simply proxy bid your max ONCE
very late in the auction.


If the price is too high, you simply do not bid. If the price
is still acceptable, then it does not matter in the least to you
how the price got to that point.


A third reason shill bidding does not work on eBay is
that whoever is stupid enough to try it will be making
enough other dumb mistakes to guarantee failure
.

A little known characteristic of Gauss-Jordan reduction
may limit the maximum number of pulses per quadrant
we can put into our Magic Sinewave calculators.

As the "n" in an nxn equation increases, the ratio of
largest to smallest coefficients gets wildly out of hand.

This is called the "stability" problem. Ferinstance, at
our n=23 BEFF, coefficients will range from 1 to over
5 million. You can read these coefficients from the
Debugging Gauss Reduction box in the calculator.

The problem triples or so with each increase of n, so big
problems can reasonably be expected somewhere around
n=30.

We already are arranging the equations "low angle columns
first"
for early near unity coefficients. And a row sequence of
alternating low-high
seems to dramatically limit the problem.

To push the limits, some sort of 128-bit math routine may
be needed. Or some gaming such as a progressive build
where the next row is selected for its least buildup
. Only
it is not at all clear what an optimum strategy would be.

A "real" mathematician could be of help here. Please

One of the least noted and horribly significant factors involving
changes in technical ( and other) writing is that we now
typeset first and edit last
. Brought about by typesetting
now being fast, cheap, under total author control, and
utterly trivial.


In the olden days, woe be unto an author who dared suggest
changing one word after typesetting. Or - gasp - having the
temerity to even suggest a possible arrangement between the
words and artwork layout in their story.


A similar earth-shattering paradigm shift is now occuring in
peer reviewed scienctific publication. Instead of peer reviewing
and then publishing, we are now going to publish first and then
peer review last.

For it is now utterly trivial to revise an already "in print" paper.


Another name for this is the "Wiki Method" and one champion of it  
appears here.
The Wiki Method can be characterized by starting off
mesmerizingly awful but rapidly converging into results that clearly
are often better than traditional peer review, ludicrously faster, and
now much more available to a much wider audience at insanely lower costs.

The traditional peer review publishers, of course, brought this on
all by theirself through their monumental stupidity and greed. It
might now take a competent researcher ten years go get approval
for traditional publication. Then then may have pay several thousand
dollars for this "right", and the final price of the journal is now so high
that the author's own library cannot afford a copy.

Plus, of course, the author's intellectual property is outright stolen.

And reprints of the article end up outrageously expensive and monumentally
difficult for an average individual to even find out about, let alone  access.

To me, traditional scholarly publishers no longer serve any societally useful
purpose whatsoever. Plain and simple, they are obstructionists standing
in the way of useful research dissemenation. Their only hope for
survival at this late date is to make any and all papers over three years
old available at zero cost with zero need to jump through any hoops
whatsoever.

I remain utterly amazed at the new thumb drives, even
those that are a miniscule 4 gigibytes. For as little as $4.

Back when I started some of this game, 110 baud was
ultra high speed, because it was much faster than most
people could type. Transmitting 4 Gigabytes at 110 baud
would take nearly 13 years. No wonder there was
immense pressure to up comm speeds to 150 baud.

At that time, magnetic core memory was a nickle a bit.
A thumb drive done in magnetic core would cost 1.60
billion dollars at eight bits per byte. More like ten-bil-
with-a-b if inflation adjusted. The "thumb" part might
end up a tad on the largish side as well.

At any rate, I'm wondering if thumb drives cannot

Here's the sourcecode and a demo plot of a new version
of some "shake the box" code useful for magic sinewave
optimization.

Whenever you quantize the Magic Sinewave math, what
were true zero harmonic reductions typically rise into the
-65 decibel region. It turns out a very few "neighboring"
magic sinewaves might end up somewhat better.
Perhaps
gaining you one to ten decibles reduction in total distortion
as well as "flattening" out the other zeroed harmonics.

The PostScript code checks out the nearest 147,420
neighbors of your selected sinewave by selecting up to
four pulse edges and then increasing, decreasing, or
leaving them the same by one resolvable increment.

Typically, a dozen results will be lower and two or
three might be useful. Some will have better amplitude
errors and some slightly worse. These can be substituted.

Note that the first uncontrolled harmonic will be
considerably larger than the zeroed ones
, although
never larger than the fundamental. Filtering and
control of this harmonic will dramatically further
reduce the lower zeroed harmonics.

Much more here.

I thought we might review some of the fundamental
Magic Sinewave numbers to see where they came from.

Early analysis made it obvious that extreme word sizes
were needed for effective magic sinewaves. Which
strongly suggests using one microprocessor for the
magic sinewave generation
and some other source for
a reference frequency that becomes the microprocessor
clock.

A ratio of a 10 MHz clock for a 60 Hertz output was
chosen
. Mostly because this was typical of earlier
PIC microprocessors.

Let's see. 10 MHz divides by 4 to 2.5MHz to become
a typical instruction cycle. Dividing by 60 for 60 Hertz
would give 41666.667 ideal clock cyles per power
cycle. One quadrant would then be 10416.667 cycles.

The number of cycles has to be an integer and should
include a factor of three for three phase compatibility.

Rounding down to 10416 clock cycles per quadrant
does this with only negligible frequency ratio error
.

This quantization level typically will increase the
zeroed harmonics to -65 decibels or better. "Nearby"
quantizations can sometimes improve the total distortion
by 2 to 10 decibels using a "shake the box" technique.


Of the 10416 clock cycles per quadrant, the widest
zero spacing on a BEF8 will typically be around 1224
counts, while the widest one spacing will often be
around 1655 counts.

Thus, somewhat less than an 11-bit delay accuracy
will be needed for a BEF8 at 10 MHz for "zeroing"
below -65 decibels.
Which nominally might double
to 12-bits for fewer pulses per quadrant.

12-bit resolution can be gotten out of an 8-bit micro
by use of some sneaky factoring tricks. Such as
calculating most of a result and using table lookup
for any residue. Delay solutions are much cleaner
if a 16- or 32-bit microprocossor is used instead.

In light of the "Let's use pelicans to sop up the oil"
Gulf crisis, it is refreshing to see at least some other
major corporations taking their risk assessments seriously.

Copper mines have these huge vats of kerosine sitting
around. Now, kerosine does have a high flash point and
it is hard to set off, but hoo boy if it goes up.

The original concept was to rename the kerosine as
"raffinite" and tell everybody that it did not burn.
A recent multi million dollar fire in Morenci revealed
some possible suboptimalities in this approach.


Which severely challenged the resources of half a
dozen volunteer fire departments. And was made
considerably worse by poor ICS.


At any rate, our local mine is now doing aggressive
risk management
. This includes mutual aide agreements,
preplanning, realistic disaster drills, much better ICS, on
site foam inventory, huge tankers ( 10X the size of normal
ones! ) and, most importantly, getting management's attention.


But I am wondering if some thinking outside the box
cannot make some simple and relatively low cost process
changes that would minimize the fire risk or eliminate
it entirely.


Ferinstance, could another nonburning liquid be floated on
top of the kerosine? Could floating balls such as are used
elsewhere in electroplating minimize the surface area?
Could some sort of an anti-flash screen be placed above
the vats?

Could lids be provided? Either all the time or falling
down from fusible links? Could effective firewalls
be placed between the four facilities? Could firefighting
wall and roof access be improved? Barriers every now
and then above the tanks? Could CO2 enrichment or
oxygen depletion above the tanks help any?


Actual out-of-pocket costs would likely be offset by
sharply reduced insurance payments, government
safety or environmental grants, and tax incentitives.

Or, the Ansul folks are really good at putting out grease
fires. Could they be persuaded this is really nothing
but a huge Mexican Resaurant kitchen?

Here's a faster and simpler scheme to reduce the distortion
on a quantized magic sinewave. It is based on allowing a
slight amount of amplitude jitter in trade for typically 2 to
10 decibels of distortion reduction of the "zeroed" harmonics:

Say you are after amplitude 0.53. Solve in "milliamplitude"
steps from 0.52950, 0.52951, ... 0.53000, ... 0.53049, 0.53050.
This will give you 101 Magic sinewaves that typically will
group into a dozen or so different distortions.
Pick the lowest.

This method is much faster than the older "shake the box"
scheme of checking out the nearest 100,000 candidates.
It also tends to better "level out" the harmonic amplitudes.
But might not be quite as optimal.

The calculator should be modified for the exact quantization
in use.

A caller asked when and where our Bitmap Typewriter and

The Bitmap Typewriter is intended to deliver the highest possible

expecially suitable for retouching text on images used in eBay

Per examples here, here, here, and here.

For larger font sizes, use of Adobe's Cleartype in a PostScript or
Acrobat PDF context is often more than suitable.

If your goal is to provide the highest possibly legibility on a small
handheld device, then subpixel techniques eclipse the full pixel
capabilities of the Bitmap Typewriter.

But subpixel techniques will NOT work with a CRT monitor
or any other analog display! They also are very display specific
in that they depend on the exact display stripe sequence and its
color count. There also may be IP issues.

The Alabama grits harvest seems to be nearing

The prefrered commercial grits tree is often gritus
arborus (domesticus)

Seeds and cuttings are normally tightly controlled by
the Grits Cooperative, and is somewhat similar to
hops distribution.

These are often preannual, but some  growers in

frost threatens.

Apparently military surplus has now gotten even
much worse than it has been. To the point of being
largely useless.

We saw a few years back how they moved everything
from Southern Arizona 900 miles to Northern Utah to
save on costs. There are, of course, no roads between
Southern Arizona and Northern Utah.

Apparently in a coverup of their stupidity, they removed
the map showing these absurdities from the web. The
initial problem was that it was costing them $1.65 to
dispose of each $1.00 in sales.


After that, there was an attempted massive recall of
getting back already sold commercial test equipment.
Followed by the leading mil surplus remarketer adding
an utterly obscene $150 minimum order.

The reasoning apparently is that if a terroriest bought
up a bunch of thirty year old commercial HP test instruments
and scattered them around at night, you could bark your shins
on them something fierce.


As near as I can tell, virtually zero test instruments or triwalls
of electronic or pneumatic goodies remain available

Here's an interesting "add a ruler" scheme for
improving alignment of portions of knocked out
bitmaps as might be used in eBay images:

Place an appropriate single horizontal or vertical line
of contrasting color well into the background.
Holding
Paint's shift key down guarantees exact alignment.

This is particularly useful for dealing with an interrupted
edge. Or with alignment of mirrored subimages.

When cutting or pasting, include the line in the object
being transferred.
Then adjust things for a perfect match
and alignment. Finally, erase the line.

How do you identify an integrated circuit with nothing but
the empty holes on a pc board it is intended to fit?

In general, this can be impossibly difficult. The chip might
be obsolete, or it might be flash programmable. In which
case knowing the part number does not help in the least.

First and foremost, try punching any part numbers into
Google. Or another search engine. Then try to use the
sci.electronics.design newsgroup.

OEM's Trade can be exceptionally useful, as can the
selector guides from Mouser, Newark, and others.


In this case, some serendipity and luck gave a
reasonable answer. The narrow DIP-24 is a rather
unusual footprint, and knowing the chip has something
to do with PWM dual bridge drivers helped bunches.

Checking the ground pins gave six of them in unusual
locations. Along with a very strange supply pin location
and an on-chip oscillator obvious source.

Candidate manufacturers
can then be isolated. Allegro
kept recurring. Searching their 13 offerings quickly
isolated their $3.92 A3992 as a probable candidate.

A weekly trade report of pv panel pricing can be found
here. In which we see present panel-only costs of $3.40
per peak watt.

This is a mere 13.6 times the breakeven point where panels
will cease being gasoline destroying net energy sinks and
actually may ultimately be capable of delivering fully burdened,
and subsidy free net energy that is renewable and sustainable.

Pricing is dropping rapidly. In part because of subsidies
expiring and removing ripoff opportunities.
But what is
interesting is extrapolating the price structure from the
previous year.  

Prices dopped in half over the previous two years. IF the
present trend continues, this would be $1.70 in two years,
0.85 in four, 0.43 in six and under breakeven in eight.


Given new CIGS developments, such price dropping
predictions would appear reasonably ballpark.

A mere decade or two after that is all that might be
needed to pay for all the previous pv energy losses,
subsidy scams, tax credits, and their amortiztion.

I was asked what I feel are the crucial issues of alternate
energy today. I see four of them...

NET ENERGY -- Not one net watthour
of pv electricity has ever been produced and no
conventiontial pv technology is ever likely to
do so. The belief that pv panels today are in
some manner renewable or sustainable or green
is an outright lie. Per this analysis.

EXERGY-- This measure of energy quality
determines whether a concept or process
can ever hope to be competitive. Excess
loss of exergy is comparable to 1:1 exchanging
US Dollars for Mexican Pesos. Ferinstance,
hydrogen via electrolysis flat out ain't ever gonna
happen because of the staggering loss of
exergy. There ALWAYS will be more intelligent
things to do with the electricity.  Per this analysis.

DOLLAR/ENERGY EQUIVALENCE-- Each
economic transaction clearly has an energy cost
associated with it. Utilities often contractally set
this equivalence near a dime per kilowatt hour.
Thus, spending dollars can be thought of as being
the same as spending gasoline or similar conventional
energy resources. You can keep score either way.  
Per this analysis.

DESPICIBLE SUBSIDIES-- It makes zero economic
or environmental sense to pay people to put business-
as-usual gasoline destroying net energy sinks on
inappropriate rooftops. Worse, the true costs of
the subsidies is nearly certain to set back the
time of net alternate energy breakeven by as
much as five decades. Per this analysis.

A preliminary version of a new Nonzero Bridged NZB Magic Sinewave
calculator can be found here.


This will shortly be moved over to our main Ultra Fast Magic
Sinewave Calculator found here with its tutorial here.

Sure enough, this is the fourth of the single phase magic sinewave familiies.
Just as the Regular Magic Sinewave has its first problem harmonics of
opposite sign to the Bridged Best Efficiency, the NZB magic sinewave
has its first problem harmonics of opposite sign to the Best Efficiency
magic sinewaves.

This family is also tunable by shifting p1s over a surprisingly wide range.
The REG and NZB families are somewhat less efficient than BEF and
BBE in that they zero out two fewer low harmonics. All four families
require 2N amplitude values stored for N pulses per quadrant.

Whether this cancellation can be exploited for filter simplification
remains to be shown
. Tuning seems to make the cancellation nearly
perfect at least for amplitudes of 0.8 and lower.

Additional "n" calculator values await funding or buyout.

I'll try to work up more of a review once the dust settles.

A preliminary version of a new Regular Magic Sinewave
calculator can be found here.

And it contains a rather astonishing surprise. The algorithm
holds p1s constant and lets all other edges optimize. This
is done to get the same number of variables as equations.

As a redundancy workaround.

The process seems to work, but it also appears you can now
TUNE p1s over a surprisingly wide range!.
Which says thaat
carrier pulses in a magic sinewave do NOT necessarily need to
be excactly spaced. Which in turn suggests zillions of new
possibilities.

One problem is picking the "correct" value of p1s given an
infinitude of choices. Chances are the "best" value will be
that which exactly meets the exact apportionment of the initial
amplitude goal.

At least at 0.53 amplitude, it is now possible to tune the
regular magic sinewave to have its first problem harmonics
to be the exact opposite of a similar Bridged Best Efficiency
one! This might enormously simplify and improve filtering.

Sadly, this appears to be "too good to be true". Every
cancellation attempt to date has introduced cosine terms,
subharmonics, or similar problems. But tuning does open
up a whole new world of opportunities.


And, if exact carrier spacing is not needed, there might be
whole new worlds of magic sinewaves remaining to be explored.

Our early analysis of Regular Magic Sinewaves was
largely dropped after our ancient and primitive "series II"
calculator
. Because the Best Efficiency Magic Sinewaves
seemed to do everything Regular did plus they zeroed out
another two low harmonics for free.


It turns out there may still be some interest in regular
magic sinewaves because they (sometimes exactly and
sometimes roughly ) complement the Bridged Best
Efficiency ones. Suggesting that some cancellations
or spectrum spreading to simplify filtering may be
possible. Sadly, all explorations to date of cancellation
have introduced more problems ( such as subharmonics
or cosine terms ) than they solve.

Regular magic sinewaves seem to have a dilemma. So far
they seem to need, say 15 equations in 16 unknowns and
thus have redundant solutions. I've found no way to exactly
write a guess-then-improve solution as used for the others
in our Ultra Fast Magic Sinewave Calculators.

However, I am exploring a scheme that may work. It says
to hold one pulse edge constant, optimize, then hold a second pulse
edge
. Rinse, lather, repeat. Early results seem promising
but bugs remain. .N
ot the least of which is whether
cosine terms will rear their ugly head.

Stay tuned as the drama unfolds.

Here's yet another way to look at why there are different
varieties of Magic Sinewaves. Which suggests yet another
family or two of them that yet have to be found and proven useful.

All of magic sinewaves appear to be based on distortionless
modulation of a carrier
. No distortion, no harmonics. At least
at low amplitudes, the spacing of the carrier pulses has to
remain constant.


Consider eight pulses per quadrant. Our earliest pulse
would have to center on 0.000 or 5.625 degrees. And end
on 84.375 or 90.000 degrees. With intermediate pulses
centered as expected.

Four cases...

0.000 to 84.375 -- Best Efficiency
0.000 to 90.000 -- Bridged Best Efficiency
5.625 to 84.375 -- Regular
5.625 to 90.000 -- New guy on the block.

We might call the new guy "nonzero bridged". It is not
clear yet what its features will be. Chances are it does
not bring much new to the table.

Note that any 0.0000 pulse will have very little amplitude
and will completely cancel itself when integrated.
This
is where our "free" extra cancelled harmonics come
from in the BEF and BBE cases.

The Delta Friendly Magic Sinewaves use a different
carrier structure. In which half the pulse edges are needed
to cancel triad harmonics.

It seems to me the fatal flaw is that any loading of the

control drive input.
And thus, unless both input sources
are nearly identical in relative power and torque, the
main input will drive the control input backwards.

Are there other Delta Friendly solutions to Magic
Sinewaves
than the 4k+3 of 3, 7, 11, 15... ?

I've been unable to find any so far, desptie repeated
searches both recently and in the past. The obvious
candidates of 4, 8, 12 ... seem to converge back to the
above series with one pulse width of zero and no
benefit in rejected harmonics.

So far, there are four flavors of Magic Sinewaves
known: Best Efficiency and Bridged Best Efficiency
that offer the highest possible number of low harmonics
zeroed for a given number of energy robbing pulse
edges; Delta Friendly that are fully three phase compatible
and require only half the coefficient memory but zero out
only 3/4 as many low harmonics, and Regular that started
it all but rejects two less harmonics than the Best Efficiency
ones.

Regular does retain the curious property that its first
unwanted harmonics are opposite in sign to BBE
. So
far, I've found no way to exploit this obvious "too good
to be true" property without introducing other gotchas
and limitations.

Similarly, no obvious tricks with spectrum spreading or
cancellation have yet been found that have compelling
advantages. Despite a lot of wheel spinning effort to date.

My present prediction is that there are bunches more
possible magic sinewaves, but finding them will prove
difficult.
And their benefits may end up questionable
or marginal compared to the original four.

The calculation math behind our new magic sinewaves
of yesterday is unbelievably hairy. Fortunately, all you
really need is the list of results from the calculator that
gives you the position and width of each needed pulse.

Just push the button and turn the crank.

An executive guide to Magic Sinewaves appears here,
with insider secrets of three phase magic sinewaves
here and a development proposal here.

Three phase magic sinewaves ( such as DF19 or DF23 )
have to meet the exacting needs of three phase power
systems. As a result, half of their pulse edges seem
to be needed to force all triad harmonics to zero
. This
leaves fewer ( about three quarters ) rejectable low harmonics
compared to the best efficiency variations. But has a
hidden benefit of needing only one half the coefficient
storage.


When the delta friendly equations are reviewed, a new
and half size smaller set of equations can be transformed.
After calculations, the smaller set gets transformed back
to the original equations.

These equations are solved by first making a good guess
and then using a sneaky trig identity to repeatedly
improve the results. Thanks to a fast converging powerful
algorithm and new advances in JavaScript, the results are
remarkably fast in Firefox and nearly instantaneous
in Chrome. Typically a fraction of a second.

Related canals go many dozens of miles and involve literally
tens of thousands of related "grid" and "mulch ring" structures.

The current R&D fund stealing alternate energy scam
de jour is a storage scheme that involves a box of hot
rocks, a box of cold rocks, and utterly, laughably outrageous
efficiency claims.


I was asked for my views on this. I have not studied it in
depth, but...

Firstoff, storage is NOT a current alternate energy problem.
Synchronous pv inversion to the power line is a currently
usable and completely solved solution that should suffice for
at least the next two decades. Nothing comes even remotely
close for simplicity, efficiency, cost, reliability, lifetime,
safety, or effectiveness.

Secondly, all that matters is NET renewable energy. Not one
watthour of which has been produced, at least by conventional pv.
Any time or effort spent not on this goal is time and effort wasted.
As are subsities that pay people to put gasoline destroying net
energy sinks on inappropriate rooftops. Net alternate energy
can be anticipated eight years after pv panel costs drop under
twenty five cents per peak watt. Until then, it is in no manner
renewable nor sustainable.

Their key question is whether a dozen regional storage units
are installed and under long term test.
With measured results.
I suspect not and thus their efficiency claims are overwhelmingly
likely to be utterly bogus fantasies. But still as good a way as
any to steal tax dollars.

Some of the problems I feel may be likely involve the way they
ran roughshod over Carnot's Law. Heat pump efficiency tends
to drop dramatically with delta-T.
Which is why domestic heat
pumps demand resistance heat emergency backup.

A second problem is that insulation becomes problematic with
very high or very low temperatures
. Radiation losses involve
the fourth power of any temperature
difference.


But I predict the gotcha that will get em is thermal impedance.
Which dramatically raises the effective low storage temperature
and lowers the effective high storage temperature. I predict
the gravel charge and discharge times will prove utterly excessive.

More on similar topics here and here.

This clearly has certain "looks like a duck, quacks like a duck"
elements. Per this discussion.

I've pretty much convinced myself that nobody cares
all that much about high tech anymore
. If an accurate
observation, the implications are staggering.

Free community high tech lectures largely go
vastly underattended. Local middle school science
fairs usually observe that "rocks get warm in the
sun". Compared to other areas whose students are doing
homemade gas chromatography or DNA replication .

Our local community college dropped their electronics
program because the football team needed the money.
Seems the subsidy of $384 for each hometown spectator
was not nearly enough.

One reason that high tech employment ( with very few
exceptions ) is not of local interest is the absence of a
unified school district.


And the reason that there is no unified school district
( forgetting temporarily that the clan wars of the 1880's
are still being fought ) is that there would not be enough

    achieving competitive capabilities well beyond
    net energy breakeven at the fully burdened
    system level.


    pv economics are overwhlermingly dictated by
    power utility avoided peaking costs which today
    average ten cents per kilowatt hour retail. This
    translates to a parity "holy grail" breakeven of
    one dollar per total fully burdened SYSTEM watt.

    Present panel costs are $3.50 per peak watt.
    For a significant net energy contribution, 25
    cents or less per peak PANEL watt is required.
    Thus, present costs are FOURTEEN TIMES
    that required for net energy production.

    Subsidies that pay people to put known defective
    gasoline destroying net energy sinks on inappropriate
    rooftops are not only wildly nonproductive, but they
    also are nearly certain to SET BACK pv net energy
    breakeven by as much as FIVE DECADFS. Per
    this analysis.

    Very dramatic developments in potential pv cost
    reductions are on schedule and in process but
    remain fraught with peril. Their immediate
    consequences are likely to be pv becoming even
    MORE of a short term net energy sink ( due to
    investment ) and to virtually guarantee that any
    conventional pv system bought today will NEVER
    serve out its intended lifetime without abandonment
    or major upgrades.

One of the most infuriating hassles of local prehistoric
exploration and site surveys is that the CCC often built
useless water control structures directly on top of or
adjacent to prehistoric originals.


Separating the two is sometimes obvious, but there are
times and places where the overlap is appreciable.

Fingerprints are reputed to last 40 or more years on
undisturbed solid surfaces. I'm wondering if the bottom
sides of CCC rocks may have fingerprints while prehistoric
ones may not.


There's bound to be a master's thesis here for somebody.

eBay has apparently just changed the details on

especially when used as an image theft detector.

Apparently eBay only visits your website when
a user requests an expanded image photo. The
regular photo is apparently internally provided.
Thus, your log will only report expand requests.
But these should be a useful indicator of total
site visitation. And certainly should flag many
attempts at image theft.

On the other hand, you will only get reports on
those offers for which you provided larger images
on your own website
.

There are two different formats in use, depending
on whether the listing is current. A noncurrent
listing will be of form...

      http://cgi.ebay.com/ws/eBayISAPI.dll?
      ViewItem&item=290210415168


and only gives you the item number. The
actual item description would take some
fancy programming involving a number-
to-description table lookup.

The current listing is more useful and
more friendly and informative....

An equally frustrating and disrupting "steal the plans"
example was the CCC
. Where they repeatedly built their
own checkdams directly on top of prehistoric examples.

In general, the differences are obvious on larger
structures. But it can be infuriatingly difficult to
decide which origin the smaller dams belong to.

CCC projects tend to be larger, longer, higher,
and more linear. They tend to be more visible
on aerial photos, Their rocks often appear to
display exceptional stone masonry workmanship.
Dams may include filled rock spillways.

Prehistoric projects tend to be less anal and much
more attuned to the land. They often will be
ill defined and incomplete. But most of all, the
prehistoric structures all have a well defined
use and strongly directed purpose.
Most of the
CCC structuresf are outrightly pointless boondoggles.

CCC projects often will have rusty oil cans
associated with them. Or rebar stakes. Or concrete.
Or, in one case, Alberto's Signature.

I just found a bunch of small dams that seem
to have both CCC and prehistoric commonality.
They sure look prehistoric, but there clearly
are a pair of larger CCC projects half a mile
upstream.

Local residents are quite adament that our hanging canals
are originals from the 1880's. They get extremely upset
with the suggestions that Granddad "stole the plans" from
preexisting 13th century prehistoric waterworks projects.

To "real" archaeologists, the evidence is quite compelling
for prehistoric origins. I'll go with Ockham's Razor on this
one and stay in the prehistoric origin camp.

Any engineering project will show evidence of the tools used.

The typical Home Depot of the 1880's would include mule
rentals, scrapers, picks, shovels, concrete, various chunks
of cast iron, and prybars.

I'd expect 19th century projects to be wider with larger
and sloppier spoil piles.
Along with at least hints of
concrete or iron. The same project done with nothing
but sharp rocks in the 13th century would likely show
a "zen like" absolute minimum disruption of the fewest
and smallest rocks and soil being moved as little as
possible.

This "zen solution" certainly seems to be the case to me.

The "tops of mesas" certainly suggests agave cultivation
rather that midwestern crops brought in the 19th century.

The very point of farming on the bajada when bottom lands
are readily available also makes no 1880 sense.

The serviced fields also seem exceptionally small and
irregular with a conspicuous lack of linear rows.


And we do have several examples where "one half"
of a canal system was adapted to modern practices
with concrete, piping, and iron headgates. With the
other half absolutely pristine early technology.

A confused viewer is a gone viewer. And very few

not found error.

Finding bad links on a large site can be a monumental
task. Getting under a one percent error rate will
often prove difficult.
But continually checking anything
that is even remotely your fault is essential.


Here's some tools I found useful for checking
large websites...

   CUSTOMER COMPLAINTS -- These should
   be dealt with first and foremost. Because they
   usually are obvious and real.

   THIRD PARTY TESTING -- A continuous
   background policy should be in place to relentlessly
   hund down and stomp out problems.

   W3C LINK CHECKER -- A free online service.
   But can be slow on broken links and misses some
   because of robot exclusion rules.

   YOUR OWN LOG FILES -- The referral portion of
   your log files can often tell you where the problem
   is originating from. But may not catch all errors if
   the reporting is 404 specific.

   ACCUMULATED LOG INFO -- By saving daily
   log error reports and totalling them with some sort
   of scripting language, the more significant errors
   will pile up and the lesser ones average out.


   CUSTOM SEARCH AND DESTROY -- A PostScript
   routine can easily compare a list of 404 phrases against a
   collection of host based web files. No actual web access
   is required and no response delays are involved. This
   routine is still under test. Earlier code is found
   here and here.

  PDF LINKS -- Adobe keeps changing their link checker
  with each release of Acrobat. Some are ready to go and
  others demand a C language compile. Try several
  editions to find what works for you. An alternate is
  found here.

  BEWARE ASP PROBLEMS -- What a typical .ASP
  file delivers may be wildly different than the program
  itself. Always check for includes. At the very least,
  the line numbers may end up different.

  THE SEARCH DOG -- The windows XP search dog
  can also test all files for error url's. No web access is
  required and the process can be very slow if many
  files are involved. But can give an overnight solution.


  WAITING -- Sometimes the problem will simply go
  away. As caches get updated, and topic popularity
  changes. Or as third party access attempts change.

I continue to be utterly fascinated by our prehistoric
hanging canal systems. Whose 1300 AD engineering
makes the LBT look like a tinkertoy set.

There are at least four, ( and possibly many more ) of
these enigmatic systems whose reach extended
many dozens of miles. Here's a typical example.

Portions even included aquaducts that were significantly
long and well above grade. The largest known of which is
abo t four feet high and over two hundred long!

These canals would usually start at the lowest
reliable water source in a mountain fed canyon.
And then create the illusion of going UP the
steep side of a mesa.
Sometimes being as much
as 90 feet above the surrounding terrain!

In reality, the mesa slopes were such that the
UP illusion was in fact an optimal water feeding
slope.
The tops of the mesas were rather poor
and extremely rocky soils. And, after all that
trouble and effort, the water sort of "fell off"
the point where the mesa ended.

Often included was a simple switching system
that let the water be routed to two or three
wildly different ultimate locations. Amazingly,
two of these systems still flow to this day.
But seem to have no major current ag uses.

Often, the areas served are of little modern
interest. Without even jeep trail access, let
alone significant ag development.

Obvious questions, such as what crops were
involved ( a "least objectionable" guess is agave ),
how the water was actually used, what sort of "transit"
device was used for slope engineering, and the
relationships between the canals and other ag
features  ( such as grids, mulch rings, and aproned
check dams ) that remains unclear and enigmatic.

Some of the most significant developments in
all of Southwestern Archaeology thus remain
pretty much hidden in the Gila Valley.

A preliminary paper appears here. Others are
in process. But the entire area remains wildly
understudied and underappreciated.

Additional champions ( and, of course, funding )

There was a recent "natural energy" landlord lein
forced sale. Based in machines that got warm in the
sun, and created supposedly recoverable pressures
as "free" and "clean" energy.

I'm wondering if some fundamental questions were
never asked of the right people that could clearly
have avoided this disaster. Such as "If it is such
an obvious idea, why has nobody thunk of it before?"


Ferinstance, let's start with Carnot's Law that
tells us that any heat engine with a low delta-T is
guaranteed to end up woefully inefficient.

Or that any thermodynamic system has its T-S
Diagram
whose area plots the temperature against
entropy and whose internal area sets the efficiency.

Or that cascaded inefficiencies multiply when several
working fluids are involved in a thermodynamic cycle.


Or that "solar anything" is unlikely to acheive more
than 5/24th the efficiency of any competing system
that
runs full time. ( Based on a 1 kW peak panel only
producing 5 kWh per day ).

Or that you have to think closed loop where each and
every portion of a full cycle is considered and not
the power stroke by itself.

Or that amortization dollars represent destruction of
existing conventional energy
. Making the overwhelming
majority of  alternate proposals gasoline destroying net
energy sinks.

Or that low duty cycles dramatically scale dollar costs.
If the energy production phase is only a small fraction
of the total cycle phase, costs go up to where they are
no longer competitive.

Such systems may in fact succeed in stealing federal
and state dollars. But there is no way in hell they can
represent any long term net energy solutions.

We've looked at the perils and pitfalls of pv solar panels
here. In which we have seen that not one net watthour of
pv solar electricity has ever been produced.
And that the
panels to date are in no manner renewable nor sustainable.


True net energy production can be anticipated eight years
or so after the fully burdened and subsidy free panel
costs drop under twenty five cents per peak watt.

Claims of "breakeven" usually wrongly treat a subsidy as an
asset,
rather than a much larger liability. For every $1000
tax credit, taxes elsewhere have to be charged much more
because of the "iceberg effect". A $1000 tax probably
requires a societial old energy burden of at least $3000, and
sometimes much more.

But there is an even sneakier and more insidious gotcha
in pv panel breakeven costs. We might call this the
"8-track factor".
As in 8-track music tapes.

As with most electronics, pv panel technology is improving
at a mind-boggling rate. There is unlikely to be ANY
interest at all in today's technology a very few years
from now. Thus, a gasoline destroying net energy sink pv
panel installed today is exceptionally unlikely to serve out its
full intended lifetime .

The case could thus be made that any present pv panel unable
to break even in five years or so will NEVER break even!

Because the new stuff replacing it will be so much better.

I've been asked about those "penny auction" sites.

These are in no manner an auction. They are simply
a gambling "slot machine" with an utterly outrageous
house percentage take
. They are also a tax on the
monumentally stupid.


In a penny auction, you buy the rights to bid, often
around a doller per bid. Prices start at one penny
and increase at one penny per bid.
The final award
price is usually very low, perhaps a few hundred
dollars for a new automobile or ten dollars for a
laptop.


Let's assume the site buys a laptop for $300. How can
they make a profit if it only sells for $10?
Well, each
bid was sold for something around a dollar. So, there
were 1000 bids to get from a penny to the ten dollar
final price. Their laptop sells  for $1010 and thus will
generate an outrageous profit.

The site also lets you bid on bids. Thus "squaring"
their potential return!
Ferinstance, say 100 bids
normally sell for $100. They open at a penny and
close at, say $19. Thus, they sell their 100 bids for
$1919 instead of the usual $100. Their cost per
bid is, of course, ZERO!

The kicker is that most bidders lose most of the time,
blowing their bid dollars for NOTHING in return.

Is this a scam? The "house take" on this gambling
operation is so ridiculously high that there is no need
whatsoever to cheat.
Yet cheating is trivially easy by
not shipping or shipping a defective or obsolete product.
Or by shilling or using automated response bots.


The entire operation is clearly online gambling, plain
and simple. At a vig that would cause a Las Vegas
Casino operator to be tarred and feathered and run
out of town on a rail.

Some stats can be found here. Of the hundred or so
penny auctions, over half of them have folded
. And the
top three have most of the market share.

An interesting ploy might be to bet on which site is going
to fold next.
Poor participation might dramatically
improve your odds. But a folding site is likely to
shill or non deliver, so the risk can be higher.

Here's an update on our current Magic Sinewave status:

Magic sinewaves are a newly discovered class of math functions
that can dramatically improve the quality and efficiency of digitally
derived sinewaves for such tasks as synchronous inverters, motor
drives, pv panels, and electric vehicles.


Magic sinewaves generate the fewest low harmonics consistent with
the minimum number of switching transitions for the highest possible
efficiency. As guaranteed by their underlying math.

Our main magic sinewave library is found here, an intro tutorial here,
an executive guide here, a development proposal here, an ultra fast new
calculator here, and prototype chip info here.

At present, the program is awaiting funding and available time for
expansion. 
Current activities include extending the calculator for
longer sequences and expecially delta friendly three phase magic
sinewaves.

Newly competitive 16- and 32- bit low end microcontrollers are
also now being investigated for their ability to simplify time delays
that are exact to a single cycle, have 12-bit or better precision, and
require very low overhead.

Spectral analysis is being further expanded and explored. Using both
newer versions of Sigview and significantly upgraded test equipment.

A possible new class of "GGMS" magic sinewaves was discovered
a few months back that would further dramatically improve harmonic
performance. Sadly, the initial enthuasiasm for this technique may have
been unwaranted.
Further exploration to date has shown only modest
performance gains. Caused primarily by introduced subharmonics caused
by the cancellation process itself. Solutions to this issue may or may not
be forthcoming.

The previous magic sinewaves certainly remain an outstanding and fully
proven opportunity.

You can email me for further details on your participation.

As we've seen a number of times in the past, there are
several good reasons to no longer accept checks and
especially money orders for your eBay selling venture.

Firstoff, checks and money orders convert what would
be an instant "outtahere by lunch" closure into what
may or may not happen weeks or months into the
dark distant future.

Second, Paypal has clearly run away with all the marbles
and clearly has become the best mainstream method of
dealing with online payments.

Third, a case can be made that anyone still using checks
or money orders just might be a felon, a flake, or an
otherwise problem oriented individual.

Fourth, many requests for check or money order payments
tend to be for very low dollar amounts. The foremost rule
to success on eBay with cheaper items is "no pissing around".

Getting circular areas to look decent on bitmapped art
can be tricky. It certainly takes a lot of practice.

This file gives you some circular patterns that are
fairly easy to use.

A second technique is to use Paint's circle or ellipse
tool to work over a white background. You can then
cut and paste a circle or ellipse segment transparently
onto your project. Note that holding the shift key
down creates circles rather than ellipses.

If you are working oversize with a high enough resolution,
you might create a red ellipse or circle and then edit
it to your needed colors. Chances are the rest of the circle
can be eliminated by suitable cutting and pasting of nearby
pixels.

Finally, powerful circle and Bezier cubic spline tools are
available in the PostScript language. You might be able to
create a PDF file and then convert it to a bitmap. Which
in turn gets cut and pasted as needed into your final art.

I'm a great fan of Ockham's Razor that says "The
simpliest explanation is often both the best and the
most correct."


Curiously, the correct spelling is in fact "Ockham"
and not "Occam". And we don't know his last name.
"William of Ockham" just tells us where he lived. As
if referring to me as "Don of Thatcher".

At any rate, I just "discovered" another local
hanging canal. It, of course, was there all the time.
Just in a place that nobody ever bothered to look.
And reachable only by cowpath.

It is astonishingly similar to a prehistoric canal
in the next canyon over
that also is hung 90
feet in the air on the side of a difficult mesa.

Ockham's razor suggests strongly that this in
fact has prehistoric origins
just like the other
one. There is no particular reason for anglo
pioneers to hang water works on the sides of
mesas. But if they already were there, then
"stealing the plans" may sort of make sense.

An expanded and updated GuruGram #92 on Bitmap
Circular Lettering
is now available. With its sourcecode
here.

This picks up our latest techniques of creating a catalog
page usable for circular dial lettering
and such. Per this
newest example which should appear on eBay shortly.

The concept is based on our "throw another million calculations
at it" such as we have used on our Magic Sinewaves and our
Fun With Fields projects. And expanded upon here.

Our Gonzo Utilities make it simple and fast to create
rotated text in PostScript. A page of all possible rotations
of all possible dial characters is created. Then, almost all
of them are "thrown away", leaving the good stuff.

72 rotations would give you 5 degree changes,a worst
case accuracy of 2.5 degrees, and an average error just
over one degree.

Colors in Paint or whatever are 256 times those in
PostScript
and thus transferrable by a simple scaling.

After creating the PostScript utility code, a recent
edition of Acrobat is used to save as a .BMP bitmap.

The bitmap resolution is chosen to create lettering
that is two to five times oversize. The lettering then
gets reduced in Imageview32 or a similar program
to provide antialiasing. TIFF to BMP conversion
can be done in Paint or elsewhere.

The process is "good enough" for larger point
sizes. The Bitmap Typewriter can still give "better"
results at extremely small point sizes. But is
far more tedius to use if numerous rotations are
needed.

Boo Hiss, part two. They did it again.

A new theoretical ( but unproven ) method of using far
less ( 50:1 reduction ) silicon for pv panels may end up
competing with  new CIGS techniques. In which nano
wires are embedded in plastic.

But the hype headlines here are screaming 85 to
96 percent efficiency.
When they really mean is
"almost as good an efficiency in unproven theory
as traditional silicon  pv".  And possibly 14 percent
real world
if they are lucky.

Turns out there is only one frequency of light
( in the near infrared ) that can be efficiently converted
by conventional silicon. Longer wavelengths are ignored and
become heat. Any "spare change" of shorter wavelengths
are also ignored and become heat.

The absolute theoretical limit is around thirty percent,
and the real world cuts this in half. There are possibly
ways to beat this limit using quantum dots and tetrapods.

Compare this hype against this paper. Or this Slashdot

Some of the more unusual features of local ag water
works are "switches" that route irrigation water to
several different locations, canals that travel along
the highest (!) portions of a mesa or bajada, and
pioneers who "stole the plans" and overlaid historic
projects directly over prehistoric canal routes.

All of which are "mountain stream" driven, rather
than involved with the Gila River floodplain.

The "Robinson Ditch" is an interesting area that
meets these criteria. And its absence of roads and
presence of cliffs may lead to some hidden surprises.

Frey mesa water can be routed to the Robinson Ditch,
to the Blue Ponds, or to Sheep Tank. The ditch itself
follows a logical but tortuous route and sometimes is
top of mesa or bajada and sometimes at the bottom.

There are hints of prehistoric ag on the satellite

Acme Mapper and others have apparently switched to

there is reduced detail and reduced info on many of
their "free" online maps.

Apparently their"for sale" maps may have better resolution

Also conspicuously absent from the web is any page that

topo and satellite imagry in any ratio

As we've seen before, our Bitmap Typewriter can be most
useful for improving ultra small lettering on bitmaps for
eBay product photos and elsewhere.

But the code can be a little awkward to use for rotated text
as might be needed for, say, a test equipment dial.


Instead, a useful alternative that works well at least for larger
point sizes is to note that Acrobat 9 has an ability to save
to a higher resolution bitmap.


Use the export image tiff option. With a higher resolution.

The strategy is simple enough: Create an intermediate bitmap
that has any and all rotations of any and all needed text.

Either in "raw" PostScript or using my Gonzo Utilities.

Here's an intermim example done to five degree resolution.

Boo. Hiss.

Recent developments at Bloom may or may not lead to
some improved fuel cell technology. But the 60 Minutes
coverage and other media and hype claims are clearly,
ludicrously, and absurdly "not even wrong".

The Bloom device is a stationary fuel cell that runs off
of natural gas. These have long been available but have been
only cost effective when heat cogeneration can offset all
the high costs, slow load reactions, and limited efficiencies.

Hospitals and laundries have been a useful match.

Purported potential advantages of fuel cells is that they
beat the Carnot thermodynamic limit. Yet none does so
today, and the latest of combined cycle modern power plants
are routinely now exceeding a 60 percent thermal efficiency
.
A figure that will be very hard to significantly beat. The best
theoretical hydrogen based fuel cell efficiency ( not remotely
approached today ) is 83 percent.

Fuel cell sizes are not all that small or "silent" when the gas
circulation machinery and synchronous inverters are
considered. The Bloom costs are so outrageous that their
customers have to steal over half their funds from local and
federal government subsidies, grants, and tax credits.

Claims that "we saved $100,000" on electrical costs almost
certainly do not fully and properly account for amortization
and true fully burdened costs. Most especially if the true
"iceberg" costs of subsides is honestly considered.
The
best use today for a fuel cell industrial user is as emergency
power backup.

Fuel cells have traditionally had short lifetimes and performance
degradion issues caused by contaminents. Extensions for fuels
beyond ultra clean natural gas have yet to be shown.
Such
contaminents as the sulfur in diesel fuel are particularly
troublesome. And, even on a hog farm, biogas is pretty much
limited to running their own ventillators. And, of course, if the
fuel includes carbon, carbon dioxide is a likely byproduct. So,
many pollution issues remain unresolved.

The hype implied that the fuel cell is a power production facility.
It is not. All it is is a natural gas ( or other super clean fuel ) to
electricity CONVERTER.
You still need a fundamental source of
net energy before you can convert it. And some sort of a pipe
to deliver it. And somebody else to buy the old net energy off of.

Comparing a fuel cell to a pv array is clearly ludicrous, and
even the media epsilon minuses should realize this. A fuel
cell is a method of converting existing energy. A pv panel
( at least in theory ) can eventually become a true NET
energy source.

Claiming that fuel cells can get you "off the grid" is also
ludicrous. As more and more net alternate energy sources
( which the fuel cell clearly is not ) emerge, the grid becomes
more and more important for brokering sources that may
be time-of-day or presence-of-wind dependent.


And, even if it looks like a pipe, it is still a "grid".

16 or even 32 bit microprocessors may end up the better choice
for our Magic Sinewaves if they are cheap enough. A key requirement
for Magsine sourcecode is that it can generate a time delay beyond
4096 cycles ( 12-bit accuracy ) to precisely one cycle accuracy.


With absolutely minimum overhead.

When attempted in an 8 bit envirnoment, "two stage" techniques
involving factoring are needed. Typically with most of the delay
being done by calculation and the remainder by table lookup.
Leading to "pinch points" in the code and making for much more

Got an email from an individual who lives near a "fast
flowing river". They were wondering how much hydro electricity
they could recover. The quick answer is "somewhere between
negligible and miniscule".
Almost certainly not enough to pay
for the equipment and its amortization.

The math can be enormously simplified by a curious equivalence:
A foot pound of potential energy is pretty much the same size as
a Joule ( or watt-second ) of electrical energy .
In fact, at a 73
percent conversion efficiency, they would be identical.

There are 3,600,000 Joules ( or roughly the same number of
foot pounds ) in a kilowatt hour. Or ten cents worth of electricity.

The slope of most rivers is amazingly low. Thirty feet per mile
is often considered whitewater.

Some other equivalences useful for your math: Power is the time
rate of energy consumption. A watt of power is one Joule per
second,
or one watt second per second. A gallon of water weighs
about eight pounds. "Pints a pound the world around". There are
7.5 gallons or 62.4 pounds of water in a cubic foot
. Water flows
in CFS can sometimes be found is sites like this one.

The usual problem with low head hydro is that enormous
quantities of water have to flow through the water wheel
or
other recovery device. Which makes for outrageously large
and expensive equipment costs.

Many of the uv-c lamp ballast combinations we are
refurbing seem to have a curious common problem:
Per the approximate schematic, the rightmost 2N2222
transistor seems to be blown. And possibly done so during
preliminary product testing.


The 2N2222, of course, is a bulletproof  "cast iron"
and
"gold standard" industrial mainstay. While used in
two other locations in the ballast, only the ( apparently )
gently used rightmost transistor in the schematic seems
to get trashed.

I am guessing that a startup transient does something
wildly wrong to pin 3 of the 53HD420
. Creating a
destructively avalanching situation. Which could
have even been the direct cause of the SMT bankruptcy
from whence these came.

There is as much as 400 volts lurking elsewhere in
the 53HD420.

One apparent fix is to replace the 2N2222 and place
a 2200 Ohm or so resistor in its collector circuit.

This might reduce any avalanching current to the
point where it may be less destructive.

But a better approach is to defeat the entire time
delay on dropout feature
by cutting the foil to the
rightmost 2N2222 collector. This converts the
ballast into a simple power-on becomes lamp-on
circuit.

The theory on uv and regular fluorescent lamps
is simple enough: Warm up the filaments and then
briefly apply a higher voltage to "strike" the plasma
arc. Then switch to a current regulated lower voltage
for normal operation.

The schematic for the uv-c ballast lamp combinations
we are in the process of refurbing appears somewhat
mysterious. At first glance, it seems a resonant RLC
circuit provides "Q multiplication" for high voltage
during initial heating. And then gets largely shorted
out by the plasma for normal operation.

The only little puzzle is this: The resonant frequency
of the LC combination seems to be around 124 kHz while
the main drive waveform is a 34 kHz square wave
.

Even if resonant at the fundamental, the voltage rating
of the resonating capacitor would be much too low. The
Q is apparently above 20, which could lead to 4000 volts
of maximum multiplication. And the resonance frequency
would exactly have to match the drive frequency without
getting into component tolerance problems.

What really seems to be happening?

The voltage across a series capacitor in a RLC circuit
is not obvious.
It starts out equaling the input amplitude
at very low frequencies, goes through a resonant peak,
and then eventually drops to zero at very high frequencies.

If run below its resonance frequency, the entire supply
voltage and possibly more appears across the capacitor
.
In this circuit, the 170 v peak square wave should be more
than enough to strike the plasma in the warming bulb.

The RLC circuit is thus  purposely run well BELOW its
resonance frequency
. At resonance, the voltage
buildup would be unacceptably high. Its resonance
frequency is apparently carefully chosen to NOT be
near any harmonic of the fundamental square wave.
Thus it is purposely spotted between the third and
fourth  harmonic. And largely tolerance insensitive.

Some further circuit hints may appear here.

Our testing of a large lot of ultraviolet lamps and
lamp /ballast assemblies is leading to some interesting
test setups and procedures.

The ballast schematic was traced by removing
the bulb for convenience using solder braid and
then backlighting with one of the new ultra cheap
LED flashlights. A new 2X Ottlight also proved
pricey but handy.

Splitting a ballast and bulb and adding a T5
four pin socket
lets you separately isolate whether
a problem is bulb or ballast related.

The ballasts are very much a hot chassis item and
fireworks will result if you use a scope ground
improperly.
I seemed to be out of stock of isolation
transformers, but I did find a 110/220/440 transformer
that was useable by splitting the 220 volt outputs and
using them at 110.

An interesting check of the crucial resonant startup
circuit can be done by using a sweep generator in the
30 kHz region
. The level and be lowered to the required
less than 0.3 volts peak to peak and the source impedance
reduced to 5 Ohms or less by a 10:1 attentuator.

One issue appears to be the resonant starting frequency
differing from the driver square wave frequency. This
is still under study. We have literally hundreds of DOA
units that should be easily repairable.

A "classic" 60 Hz fluorescent startup circuit should also
give an independent check on bulb operation. Most any
transformer primary that limits ac current to 300 mils or
so at 80 volts should work. A pushbutton connects the
filaments initially and its release should produce a
high voltage flashover transient to provide the initial
plasma.

problems with these units from a SMT bankruptcy.

One problem in understanding is that Lorenz Force equations
have to be used instead of Faraday Induction equations. A
second is that you cannot tell when or if a uniform magnetic
field is rotating
. Per this classic paper. Or this simple
experiment

I know of no commercial homopolar devices for sale, and
their last practical use was many decades ago. These days,
it is cheap, efficient, and trivial to convert regular ac or dc
levels into low voltage high current when and where needed.


Counter EMF's and conservation of energy is alive and well,
in all homopolar devices. Just as would be expected.

Org, part II. A database revision to Spyware Doctor apparently
removed more of our Internet Security 2010 virus. All ugly
messages are now gone, and none of the original filenames
seem to remain present.

The only obvious remaining trace is that green wallpaper is
forced on the desktop
and the Desktop Change feature is
locked out of the Control Panel. Apparently this applies only
to one user
and should be fixable by creating a new user and
moving one file at a time to their account.

I'm still going to wait a few days to see what Spyware Doctor or

Despite some good firewalls, use of Firefox only,
passing Shields Up with flying colors, and extreme
downloading care, we managed to pick up the
Internet Security 2010 virus. Most likely from a
video download site.

The virus trashes your desktop wallpaper then gives you
all sorts of bogus and unremovable "infected" messages
to try and con you into a "we can remove this" paid
subscription. The virus is highly infuriating but not
especially destructive
.

Legitimate methods of at least reducing this virus are
available through Spyware Doctor. or Malwarebytes.
Otherwise, manual removal can be dangerous and painful.

However, my first attempt at using Spyware Doctor
apparently removed most of the virus files and any
detection of them. But left the desktop wallpaper
trashed and one ugly message remaining.


If you have any suggestions on how to fix this
problem, please email me. Present strategy is to
wait a few days and see what shows up on the
newsgroups. Or if Spyware Doctor cleans up their
repair with new updates.

Most wallpaper would have a .png, .jpg, .gif, or
.bmp extension that can easily be cataloged with
the Windows XP search dog. With the theory you
could simply replace it with something benign.
Nothing obvious came up on first try here.

Again, please email me with your solution.

What is the math behind the "dollar per peak watt" holy
grail of pv panels?

Well, the dollar per peak system watt is the price level at
which a pv panel ceases to be a gasoline destroying net energy
sink and finally at long last becomes totally pointless.


Taken in pv totality, not one net watthour of silicon pv panel
electricity has ever been produced!

At this price level, the panels, of course, remain NOT in any
manner green, renewable or sustainable.

Assume you have a system that produces 1000 peak watts at
noon. And that a utilitiy's avoided cost afternoon peaking is a
dime per kilowatt hour. A one kilowatt peak panel can thus be
expected to produce five kilowatt hours per day realistically.
Equal to fifty cents worth of peaking electricity.

Per this amortization shedule, an investment for ten years at
ten percent that costs fifty cents per day would be $1135. Or
( nominally ) just over a dollar per peak watt.

Naturally, that is the total system cost, INCLUDING the
synchronous inverter, all labor, maint, compliance, and
installation. To reach this holy grail level of a dollar per
peak watt, the  actual panel costs would likely have to drop under
fifty cents per peak watt.


At the dollar per peak system watt level, it makes no sense
for a utility to buy in, because all they would be doing is selling
a conventional peaking watt for a dime and using that same dime
for buying a dime's worth of pv solar. AKA "paint it green".

In general, since the utility has much better economics than small
scale individuals, it makes even less sense for an individual to buy
in at the dollar per peak watt system level.


To become a genuine renewable and sustainable net energy source,
system costs would have to drop significantly below the holy grail level.
Perhaps a quarter per peak panel watt to actually displace traditional
peaking sources.

It likely would take many years after the quarter per peak panel
watt is reached before any long term actual energy breakeven is in fact
reached. And with new CIGS investments, net pv energy flow is bound to
get a  lot worse before it imporoves.


The California initiative ripoff alone is likely to set pv energy breakeven
back by as much as half a century!


Up to that point, the panels remain gasoline destroying net energy sinks
that are not in any manner renewable nor sustainable.
And certainly
not green.

Much more here.

Some of the solid state ballast circuits for fluorescent
and uv lamps involve fascinating new engineering. Here
is an approximately correct schematic for the ballast
we are providing for several of our eBay uv lamp offers.

And a paper on somewhat similar circuitry appears here.

One key component is an ultrasonic self-oscillating half bridge
driver
such as the International Rectifier IR53HD420. This
converts a pair of line power supplies into a 163 volt square
wave, typically at a 35 kHz or so rate.

The square wave is fed to an inductor. The inductor can be
much, much smaller than a traditional ballast because of the
higher frequency. It also can be quieter and more efficient.

During the preheat startup, the inductor is resonated (!) with
a suitable capacitor in series with the bulb filaments.
After
startup, the inductor acts as the usual current limiting ballast.
With the bulb's plasma largely shorting out the capacitor.

The ballasts are very much a "hot chassis" circuit. An
isolation transformer is a must
when viewing any scope
waveforms. Otherwise, connecting a scope ground lead is
certain to cause fireworks.


We have both short wavelength uv-c bulbs and ballasts
available here.

It is the greasy whistle that gets squeaked.

Our state legistlature has, in their infinite wisdom,
closed both a local state park and their fire marshall's
office.

Yeah, it is easier to bitch when your own ox is getting
gored. But the loss in state sales tax would dramatically
and clearly exceed the park's budget deficit.


The fireman certification program to date has resulted
in dramatic improvements in volunteer orginizations.
With substantial reductions in insurance premiums for
most of the state. Stopping such things as arson investigation,
school safety programs, and annual and regional fire schools
also seems equally and monumentally stupid.

Yeah, there's major budget issues. But cutting things on the
basis of who will bitch the least cannot possibly end up optimal.

I was recently asked for my views on "global warming".

After many decades of careful observation here in the southwest
over such things as flood and fire frequency and severity, overgrazing,
species invasion, overbuilding, water management, and drought,
I firmly believe that...

Climatic and weather VARIABILITY are dramatically
on the rise and will continue to become worse
for the forseeable future .

Much, if not most of the increase in variability
appears to me to clearly be man caused.

Business as usual will no longer hack it.

We better fervently HOPE that the majority of the
problem is in fact man caused; Otherwise, it will
surely end up MUCH harder to fix.

Yes, the situation is enormously complex. Yes, outright
mistakes will be made. Not to mention unintended consequences
and hidden agendas. But, at least to me, doing nothing would be the
gravest and greatest mistake of all.

My own feelings are that "carbon free" is a monumentally
stupid goal.
"Carbon neutral" makes infinitely more sense.

And that silicon pv panels are an outright scam. When taken
in their totality, not one net watthour of pv energy has ever
been produced!
As proven by not one power utility yet using them
for fully burdened, subsidy, R&D,and greenie free profitable peaking
energy. The panels remain a gasoline destroying net energy
sink and will likely remain so untill eight years or more after their
fully burdened price drops under twenty five cents per peak
watt
.

Meanwhile, the entire scam is in no manner green, renewable,
nor sustainable. It ain't even close.

More here and here.

May you live in interesting times.

Much historical and engineering data is about to "poof gone"
vanish unless new web champions can be found.
The impact
on this on American engineering cannot be oversstated.


For the new paradigm is that "Iffen it ain't on the web cheap
or free, it doesn't exist".


Tremendous strides are being made in some areas. Ferinstance,
All of Desert Magazine can be found here. And much of Heathkit
here. HP ( now Agilent ) is aggressively making most of their legacy
documents available free on the web. While Tektronix has released
theirs to the public domain for low cost availability.

Sometimes who owns what becomes muddled, and things can end
up as catch can. While rights to Popular Electronics and Radio
Electronics
remain available ( Contact the Marana, Arizona city
council! ) , no champion has emerged to offer all of everything.
Although myself, Jeff Duntemann, and Michael Holley and others
are hosting various bits and pieces for our own nefarious needs.

But obstructionists like the IEEE and Elsivier steadfastly insist in
shooting themselves in the foot by refusing to make any and all
technical papers over three years old freely available on the web.

One recent example that begs for a champion: The first road over
the Big Lue mountains in Greenlee county ran smack into a volcanic
piton core. So they simply tunneled thru it, similar to the holes
through California's redwood trees. That photo used to be piled
six deep here in the Gila Valley. Yet I've found it impossibly
difficult to locate on the web
. Surely it is public domain.

The tunnel itself is long gone, having been trashed when the
road was more recently paved. And thus a tunnel-in-the-volcano
champion is sorely needed.

And still at a sensitivity level detectable with our
current technology. And new candidate star systems are
being contacted at a cube law rate, while the energy
levels are only dropping square law.

If you try Googling on a topic that is "too thin", you might end
up with mostly false hits or "wildly wrong" responses.

It seems that I mentioned a company with an odd name spelling

they were clearly in the "what are they on and where do we get

Somebody Googled them, and we ended up in slots #2 and #3
in the response! They ended up calling me and insisting that I
was a source of supply for their "action at a distance" utter
