Yech. I can't do ragtime very well. Actually, I can't play anything
very well (mostly self-taught). Of course, it's not me as I prefer to
blame the instrument.

Some ancient and full of mistakes live MP3's of my elevator music,

I don't know why you would want to "see" me play. 3-5 minutes of my
banging on the synthesizer would certainly be rather boring. Well,
maybe a short YouTube video.... Yet another project.

Unfortunately, I think that the skill levels of many editors, don't match
those which you seem to possess.

During a Unix book edit and ordeal, I was rather amazed to discover
that I was being paid more as tech editor than any of the authors
involved in the production. The result was predictable. The authors
produced garbage and I was expected to clean up the mess. Even worse,
the authors were paid by the page, which provided the incentive to
produce voluminous garbage and excess verbiage.

I think that many believe that just because
an article has been passed to them for 'editing', it must then be altered
and generally 'messed about' in order to justify the fact that it *has* been
passed to them, and that they have earned their fee.

Correct. By definition, everything I touch is improved by my
involvement.

I have had articles
that I've written, totally mauled by an insensitive hand.

I haven't done that to any articles. However, I have done the same to
science fiction business plans and project proposals. The only
difference between those and articles is the amount of money involved.

Words and phrases
that I've chosen very carefully have been changed or removed, resulting in
(sometimes) a complete reversal of the intention of a whole paragraph, let
alone a sentence, indicating that the editor had no understanding of the
subject material, nor the people who were its targeted readers.

Yep. I was once interviewed by a local newspaper reporter on some
technical subject. When the article appeared, I didn't recognize any
of my quotes, statements, or allegations. It was as if someone else
had been interviewed. I correctly deduced that this was normal.

For many years afterwards, there were various attempts to interview me
on similar technical topics. Instead of honestly stating my opinion,
I changed to irreverent humor, arcane analogies, and bizarre
statements, all calculated to drive the editor(s) insane. I may have
been successful because the local newspaper sold out and left town.

I have also had grammatically correct structures changed into ones that are
not, and correct spellings changed for wrong ones.

Incorrect spelling is a great way to distract the reader from the
topic. Spelling errors are instantly perceived by the reader, while
logic error, political agendas, and editorial bias take much more
effort.

By the same token, I
became very close to the editor of one magazine that I wrote for, and he
told me that my copy was a pleasure for him to work with, because the only
'editing' that he ever had to do to it, was an occasional slight precis-ing
of a paragraph to make the article fit the space available. This was always
done very carefully and sensitively so as to impact on the content as little
as possible.

Editors lie. I know because I'm an occasional editor. I suspect that
your editor wanted something from you and found flattery to be
effective.

I think that one of the main problems with the publishing industry in this
regard, is that these days editors tend to be self-employed contractors who
find themselves editing a great deal of very varied subject material, so
have to employ the same basic 'one size fits all' techniques to those works,
and that's where it can go wrong. In days gone by, an editor was an employee
of the magazine, and usually had a deep understanding of both the subject
matter and the people who would be reading it.

Not really. I was never asked to edit something with which I was
unfamiliar. On the business plan reviews, it was always on a subject
with which I was totally familiar. The one review where I fell flat
on my face was a rush job on an unfamiliar product area. In the book
reviews, the publisher actively searched for experts in the field to
do the reviews. Lack of familiarity might be a problem in popular
magazines and newspapers, but for technical articles in technical
publications, the tech editors are usually quite familiar with the
technology. The style/grammar/spelling/fit editors may have been
non-technical, but they are not suppose to change the meaning or
technical content.

As a slight aside, you mention that some people write as they speak. Some of
the best technical publications that I have read, have been written in this
style. One that springs to mind was a booklet on repairing Bally pinball
tables, written by one of Bally's in house service team. It was written
exactly as one engineer would talk to another, and was both amusing and
practical. A perfect joy to read.

"As one engineer would talk to another.."? Was the booklet all in
acronyms?

I suspect that you haven't read many depositions or stenographic
records of court proceedings. People do not speak in anywhere near as
precise a manner as they write. The resultant transcripts are often
redundant, fragmented, and ambiguous. There are authors that can
write in a "home style" manner, intended to sound like a personal
discussion. The idea is to put the reader at ease and present the
topic from a non-threatening position, rather than from an
academically correct lofty position. It consists of adding prefixed
and suffixed phrases to each paragraph or section that sound like
conversation. Books written by those with considerable customer
contact experience tend to write like that. If there's room, such a
"home style" is usually left after the various edits. If the
publication needs space, it's the first to be removed. I once ghost
wrote an article for a radio magazine. When the article appeared, a
paragraph of radio lingo had been added to the front and rear. To
make room, two important paragraphs were excised. I was not thrilled.

I think that you do yourself an injustice, Jeff. I rather liked your playing
on those clips. A little 'strident' or 'full' in places, but I think your
touch is quite nice, and it's certainly a lot better than some I've heard
who are supposedly professionals ...

Thanks. Long ago, I wanted to do music full time. I was advised that
there were plenty of engineers that play music in their spare time,
but no musicians that do engineering in their spare time. I got the
point and concentrated on engineering and ignored music.

A little 'strident' or 'full' in places, but I think your

Of course it was harsh and loud. I was trying to kill the
synthesizer. As with poetry, I do my best work when I'm angry and
irate. I've been told that I do the emotional content or "feeling"
part fairly well. Now, all I need is some target practice hitting the
correct keys. The problem is that the more I practice, the worse I
play. Can't win.

break loose before the SMD package broke. must be some damn good
epoxy,wish
I knew who makes it and where to get it!


Belt and braces , to take the mechanical strain off the solder? To scrape
back the epoxy to a clean board , the action of a soldering iron tip on it,
was like the normal reaction of solder-iron heat to epoxy, goes powdery .
Perhaps its bright red as a warning

Red? Sounds like somebody used Loctite Red, (permanent liquid gasket
compund).

I've never seen epoxy used to hold a part to a PC board. A tiny dot
of a red glue was used on our boards, and it would release when you
desoldered the transistor leads. Any rework at the factory level used
very thin solder wick to remove the solder, and a very thin curved
'dental pick' to lift each lead while the joint was still hot. If the
glue was still holding, you touched the transistor with the soldering
iron to free it. If you worked fast enough, the glue was loose when you
unsoldered the last lead.

If I can find my old rework tools, I'll make a video & put it on
Youtube. I'm finally able to spend a little time in my shop, after 5+
years of health problems.

That sounds like the standard thermoset glue used in PCB assembly.

Have seen thermo curing glue used when SMD and leaded components are
used in a mix on a single sided PCB.
First step in production was to place all glue dots for smd.
Then place all SMD components and cure glue in a reflow oven.
Then place all leaded components and run through the wave solder machine.
In this proces both SMD and leaded components are soldered at the same
time and the glue is to assure that the SMD components do not fall of
during soldering.

BTW the glue was red.

That sounds likely , a mixture of SMD and thru-board componentry on this
pcb. More glue than the dot that would normally be used just for holding SMD
in initial placement.

There was another feature of it I'd noted but dismised ,thinking it was just
due to thin film "dilution" of the colour. The exuding glue blobs around the
SMDs was bright red but the underlying thin material was more beige or peach
in colour - perhaps a side-effect of reflow oven and air exposure while
curing

Thank you. It's just hot & humid in Central FLorida at the
moment. We recently had several days of heavy rain, and a couple
sinkholes in this county from the rain. The problems on the east coast
are north of here. Some areas around Washington DC are without
electricity & running water after recent storms. Luckily, they'll never
run out of hot air.

Ocala and Panhandle-area got the worst of it,with a lot of new sinkholes.
It's a bummer when a big hole opens up next to or under your house and
things start falling into it,your foundation and walls crack,or part of
your home literally breaks off.

Central Florida(Orlando area) didn't fare too badly. Our drought had kept
the lakes and retention ponds low so there was plenty of room for all the
water. We're still 2.5" below normal for rainfall.

Hi Jim

I've visited the area many times over the years, and have been there at most
times from winter, through early and late spring, and through into autumn
(fall I guess that is your side). I have only been once right in the summer,
and I found it a bit too humid for me. I seem to remember that it poured of
rain at three o'clock every afternoon for about a half hour, and then dried
right up again. I think we had some pretty damned good thunderstorms as
well.

It's going to be a big bunch of us again this time. Just had a grandchild
presented, and another due in about five weeks, so it will be a full three
generations thing. Would have been four except my mother died a little while
back. She loved it there (and Vegas !). She was well into her eighties and
still enjoyed jumping on a 747 and flying across the Atlantic

Are you actually in Orlando itself ? We usually take a house for a couple of
weeks in Kissimmee, way down Poinciana Blvd at Cumbrian Lakes. Maybe we can
meet up for a beer or something while I'm there ... ?

yeah,that's typical Florida summer....

did you know that the "lightning capital" of the US is centered in this
area? Also,the lightning power density here averages twice that of
lightning up north.

I'm way north of Orlando,in Seminole County,while Kissimmee is in
Osceola,on the south side of Orange County where Orlando is.
Plus,I don't drink any more,got tired of it,I stopped about the time the
blood alcohol limits went from 0.1 to .08 and I had just got my Concealed
Weapons Permit too.
But thanks for the invite!

Hey,while you're here,try to visit Skycraft Surplus;I-4 at Fairbanks in
Winter Park.
It's a neat electronics surplus store,has a big rocket on the outside,and
some dummy practice bombs and missiles hanging from the ceiling inside.
Unfortunately,they don't have lots of old test equipment like they used to
have.I used to enjoy seeing all the used TEK scopes and other stuff they
had.

I'm still trying to figure out why epoxy was used to hold a SMD on the
board? thermal-conductive epoxy?


I've never seen epoxy used to hold a part to a PC board. A tiny dot
of a red glue was used on our boards, and it would release when you
desoldered the transistor leads. Any rework at the factory level used
very thin solder wick to remove the solder, and a very thin curved
'dental pick' to lift each lead while the joint was still hot. If the
glue was still holding, you touched the transistor with the soldering
iron to free it. If you worked fast enough, the glue was loose when you
unsoldered the last lead.

If I can find my old rework tools, I'll make a video & put it on
Youtube. I'm finally able to spend a little time in my shop, after 5+
years of health problems.


Glad to hear you're feeling better Michael. How is it in Fl at the moment?
We're seeing pictures on the TV here of widespread flooding and power loss
down the eastern seaboard, I think they said ??


Thank you. It's just hot & humid in Central FLorida at the
moment. We recently had several days of heavy rain, and a couple
sinkholes in this county from the rain. The problems on the east coast
are north of here. Some areas around Washington DC are without
electricity & running water after recent storms. Luckily, they'll never
run out of hot air.

Yep, that torrent inflicts the whole world. It is a component of the
Santa Ana winds what inflict Lost Angeles from time to time.
