Excellent contribution...

I am interested, did you use fine reader for scanning or another? And, did
you use adobe to create the .pdf or other free software? Is the .pdf text
searchable (in text format) or not (in graphic format?)

Warmest regards,
John

The work was done using only noncommercial (freely-distributable)
software tools... the SANE scanning software, NETPBM image-processing
programs, The GIMP for manual image processing, and GPL GhostScript to
create the PDFs. I wrote a bunch of custom scripts to perform some
higher-level functions (e.g. automatically levelling, centering, and
"bleaching" the pages).

The text is not searchable. I don't have access to OCR software which
can do the job with acceptable accuracy, nor the time required to
proofread the whole book and correct the inevitable errors. The PDF
text is all in graphic format.

The original scans are 300 dpi grayscale, PGM (portable graymap)

The data in the PDF itself is 300 dpi one-bit-deep black&white data,

Not familiar with it, don't really care to be. I have a policy of
avoiding the use of Microsoft software on my systems except when no
decent alternative exists.

I am not sure if there is a counterpart in the Linux
world...


Adobe Acrobat Reader has a "continuous, facing" display option - pairs
of pages side by side - which I suspect is close to the "paperback
style" to which you refer. Works fine with the PDFs I'm distributing.

are you dual boot?


No, I don't trust that mode, for a couple of reasons. Some M$
operating systems are known to rather aggressively overwrite or
destroy other OS's partitions or boot blocks, sometimes without asking
or warning. And, given all of the security exploits against Windows
and Explorer and etc. floating around, I feel safer not allowing
Windows to have direct access to my hardware.

I do occasionally run Windows (usually Win98) in a VmWare virtual
machine, with a virtualized hard drive, for things like tax software,
ham-radio programming utilities, etc.. That way, it's running safely
in user mode, can't get to the real hardware, and I can wipe it and
start over from a checkpoint save without affecting the rest of my
system.

Getting it down to 1 meg would necessarily sacrifice almost all of the
detail in the photographs - they'd be unviewable. 1 meg might be
enough space for the text, and possibly for the black&white charts and
line drawings (as bitmaps) but the photos would be lost.

The pics would be converted to .jpeg... the text, in an efficient ebook
format, would be held compressed--very small... I did say one-meg+, I was
thinking about the pics (graphics) when I included the '+'... black and
white compresses very small, gray scale not as well... still, 33 megs is
HUGE! I don't see it being any larger then 3 megs at worst case... 1/10 is
good...

The reason it's 33 MB and not 1 MB is because the .pdf file is
basically a bunch of pictures, one of each page. That's also why it's
not searchable, and why you can't cut and paste text out of it.

33 MB is on the small side for books scanned like this.

In comparison, the Bible is only 1.34 MB in size in text format after
being compressed (http://www.gutenberg.org/etext/10) -- and it's a big
book. Even War and Peace is only 1.16 MB
(http://www.gutenberg.org/etext/2600).

In order to get it under 1 MB, you'd generally have to use some sort
of OCR software to convert the picture of text into text. I presume
there would also be some pictures, and they'd have to be stored as
pictures, of course.

Unfortunately, good OCR software is hard to find, and I know of no
software that could take a book, scan it, convert it to text and
images as appropriate, and do it accurately enough that a human
wouldn't need to proofread the entire document carefully. And that is
a very large job.

The reason it's available with BitTorrent is because that allows lots
of people to download it relatively quickly without totally sucking up
his bandwidth. It may be a bit more work to download than something
that's just a link on a web page, but it works nicely once set up.

In any event, scanning and distributing out of copyright books like
this is a worthy endeavor. Thank you!

Looks like there's a few other radio related works on Project
Gutenberg. Go to `http://www.gutenberg.org/catalog/world/search' and
search for `radio' for a list. None seem to cover antennas
specifically, but ` The Radio Amateur's Hand Book' looks interesting.

John Smith May 23rd 05 06:10 AM

Fine Reader has no equal, still must be proof read, but I am always
surprised how accurate it is, when pages have been scanned at high enough
pixels... 200 is good, 300+ is excellent... it is smart and knows pictures
when it sees them... all this is easy to suck into word and put a book
together rather quickly... microsoft provides a FREE (what was Bill
thinking!) plugin for Microsoft Word which will construct a .lit ebook from
any word doc and presto... you have a ebook of excellent format--and even
with pics--small...

The guys on the #ebooks chan on the undernet servers of IRC used to provide
such books and info on how to create them--it is where I picked it up at...
they create books in all formats... but for quality and size, .lit is what
appeared best to me... microsoft provides a FREE (what was Bill
thinking?--again!) reader to read them, called "Microsoft Reader."

Warmest regards,
John

Hi Doug,

Also from Gutenberg (along with several dozen other titles) is my copy
of Casanova's Memoires (which fits in my Palm Tungsten E as an ebook).
It runs to 3.9 MB (about two feet of bookshelf space). No pictures by
the way.

You might consider being a bit less quick to toss off those
stereotypes, John. They can blind you more than they illuminate.

Probably about 90%+ (at the very least 80%) of all computer users are
windows based... I simply think of the biggest audience (greatest
good-greatest number, America used to be like that--I miss it...)


.... and all of those Windows users can, if they choose, view PDF
documents. "Portable", y'know? The Adobe software is free, and works
fine.

What I'm not particularly interested in doing, is creating a
non-portable (Windows-specific) version. Why restrict the usability?

If you want to do so, go right ahead... as long as you comply with the
simple "noncommercial, share and share alike" copyright terms on the
PDF, you can create a further derivative work to suit yourself.

I'll be curious how many tens, or hundreds of hours of work it takes
to develop a suitably-high-quality textual representation of this
book. Do let us know!

I go between Linux and Windows as necessary, my recreation machine is
Slackware based (mp3s, movies, personal coding, etc...) ... Mac I avoid
(but, they can run Linux)... those guys (Mac'ers) are worse then Bill when
it comes to proprietary rights and control...


And that's pretty much why I stopped using (and developing software)
for my Mac, put it into retirement, and switched to Linux. (Could
have been a *BSD derivative, but there was a big two- or three-way war
going on within the *BSD camp at the time).

.pdf is great, but huge...


By today's standards?

I thought you were more interested in the free sharing of info than fighting
operating system wars...


I am. You raised the subject, and I simply answered the question to
explain why I'm not personally interested in doing what you want.

I've done what I set out to do - get this work back into public
availability, in a useful form. If that form does not suit your
desires, that's your issue, not mine, and you're free to correct the
situation.

John Smith May 23rd 05 07:26 AM

Dave, I said an excellent contribution on your part--few will do as much,
here I just repeat what I have already said...

Nothing wrong with .pdf, except it is too large... and in the case of all
graphic content--not text searchable... .lit just gets things a bit more
right, the format is easier to read, and it provides "text to speech", it
will read the book in audio for you--even the visually handicapped can
"read" it... and it is all free to make and read... (well, you have to have
MS Word access)

I have access to a scanner which, if the back rib is cut off a book, and
pages freed, scan a whole thick book in minutes--I have hand scanned books
on my home scanner, a high speed scsi HP, and it does take a bit of time and
effort--I am sure you did the same with the book you are speaking of, and
know well that task... on a fast computer, conversion of a page by fine
reader is seconds... it really just depends on how good the scanned images
are... much less than 5 secs a page for good quality--scanned images...

I was hoping the "bookworms" on Linux would have come up with a compatible
reader for Linux for .lit--I haven't searched--but is an excellent format to
just ignore for petty battles--however, MSs' rights on it may make this
impossible...

However, there are other routes to take too, one is .html, all platforms can
read it and there are ebook creation tools which create to this format (pics
can still be .jpeg's)--and can be read with any browser, ms word, the
freeware star office for linux, html editors, etc...

We live in the land of computers--no task is impossible--many roads all lead
to the same destination(s)... a good broad picture of what is available is
good to have... I am sure I have not been able to find all which is
available... still got the eyes open...

The ONLY "fault" I was finding is the size... download time... storage on
disk (forget floppies, fill up a zip disk, cdrom quick with books that size,
etc)...

I did not intend for you to see my comments as a "slur", rather I respect
your work and your contribution... and like I said on my first post here,
THANKS!!!

I think "Linux Warrior" is accurate... even your post I respond to here
seems to mention and reinforce your commitment to Linux... no big deal...
the corp. I work for does work in both Windows/Linux, I don't have an option
to ignore one or the other, I have no real problems with Windows XP,
Microsoft finally started doing something right... I came from the
commandline prompt in UNIX, then to DOS... was shocked when Linux went
GUI... but got used to it quickly...

Nothing wrong with Linux Warriors... one of my best friends is a general in
the army...grin I just think of myself as living in a "neutral country"
(like Sweden) when it comes to religious and political commitments to an
OS...

Warmest regards,
John

You might consider being a bit less quick to toss off those
stereotypes, John. They can blind you more than they illuminate.

Probably about 90%+ (at the very least 80%) of all computer users are
windows based... I simply think of the biggest audience (greatest
good-greatest number, America used to be like that--I miss it...)


... and all of those Windows users can, if they choose, view PDF
documents. "Portable", y'know? The Adobe software is free, and works
fine.

What I'm not particularly interested in doing, is creating a
non-portable (Windows-specific) version. Why restrict the usability?

If you want to do so, go right ahead... as long as you comply with the
simple "noncommercial, share and share alike" copyright terms on the
PDF, you can create a further derivative work to suit yourself.

I'll be curious how many tens, or hundreds of hours of work it takes
to develop a suitably-high-quality textual representation of this
book. Do let us know!

I go between Linux and Windows as necessary, my recreation machine is
Slackware based (mp3s, movies, personal coding, etc...) ... Mac I avoid
(but, they can run Linux)... those guys (Mac'ers) are worse then Bill when
it comes to proprietary rights and control...


And that's pretty much why I stopped using (and developing software)
for my Mac, put it into retirement, and switched to Linux. (Could
have been a *BSD derivative, but there was a big two- or three-way war
going on within the *BSD camp at the time).

.pdf is great, but huge...


By today's standards?

I thought you were more interested in the free sharing of info than
fighting
operating system wars...


I am. You raised the subject, and I simply answered the question to
explain why I'm not personally interested in doing what you want.

I've done what I set out to do - get this work back into public
availability, in a useful form. If that form does not suit your
desires, that's your issue, not mine, and you're free to correct the
situation.

So when are you going to stop talking and do it? Otherwise take what's
available and stop whining and putting down other people choices (i.e.
SHUT UP). 99% of us couldn't care less what your opinions are- as in
"sharing them" - you've managed to insult and alienate many people here

I've got reasonable bandwidth resources, so I've put up the 'printer'

available. http://www.r-bonomi.com/radio/

The server does impose limits on transfers --
it rate-limits that file to 16kbyte/second,
so the download will take almost an hour.
it will also allow no more than 4 simultaneous downloads.
It gives a polite error, if the session limit is reached

Enjoy!

John Smith May 23rd 05 05:55 PM

Well, gee, I was so enjoying the fact you were out there reading my posts,
what a disappointment now that you have went and dropped me in the old bit
bucket...

And, gee, I did come here just to sit around and idolize everyone... guess
my coarse nature prevents that--oh well, we all have to work with some kind
of handicap--guess we will all survive...

Thanks for pointing out your opinion(s)--I will surely keep it/them in the
back of my mind... perhaps at some future date it/they will be useful, no
knowledge is without merit...

Don't attribute more to me than I am capable of though, can't really take
the credit for "alienating" anyone--they all have free wills and do as they
please--really, I don't have that much control over people--it is really
their strengths and weaknesses which limit or raise them to the heights they
find themselves standing at... thanks for being so flattering though...
unless you meant I should suffer others "control freak" natures--then I must
decline...

Since I have been in the exchange of text, here is this thread-all I have
gotten is a list of won't work, shouldn't work, isn't supposed to work and
might be illegal or offensive to "radio gods"-I don't work that way-indeed,
if the purpose of this is to stop anything-it has exactly the opposite
effect. I can tell from the lack of young and dynamic minds here that you
have been successful, either by intention or not, at quelling all but
conversations revolving around tried and true ideas and in the discussion
and worship of ancient texts-which are obscure and difficult to obtain and
hinder learning by those very facts. interesting way to "run a ship" but not
very conductive to getting anything done. I think most tire of this and
move on-leaving a bunch of grouchy old farts that wish to get back to
worshiping some ancient ham/author that wrote a book/article a few decades
ago. and not be bothered with having to think. not surprising that amateur
radio reflects what is done/said here... and suffers for it.

While this may please some-it does not please me-one must ignore this all
and move on. if you or any others need "ego stroking" perhaps there is
already such a newsgroup thread, or, one could be created. I am almost
positive you will find what you want there-certainly, if not, you will be
left alone there--most likely with others of your ilk--perhaps this will
generate a need to start up a mutual admiration society, and another
newsgroup thread will spring to life.

Warmest regards,
John

Many thanks for doing that, Robert! If your server keeps stats, could
you let me know how many downloads it sees over the next few weeks? I
admit to being curious.

FWIW, the BitTorrent tracker reports a total of 60 completed downloads
so far - 21 of the smaller ebook version and 39 of the printer-
optimized version. I find that to be a very satisfying response, for
a day and a half of distribution of an admittedly obscure text... I'm
glad so many people were interested.

I'll be leaving the BitTorrent tracker and seeders running for the
forseeable future. HTTP access is certainly more convenient for most
folks, and for handling sporadic occasional downloading. I may shift
my home system over to doing both sorts of distribution at some point
in the future, when I'm fairly sure that the rush is over.

Thank you both - especially Dave, for taking all the trouble to produce
such good-quality scans.

Of *course* it keeps stats. What fun would it be otherwise? grin

In the 2-1/2 hours since I posted the notice, I've had 7 full downloads,
and a couple of aborted ones.

And one guy _did_ get turned away for a bit, because there were already
4 downloads running. :)

Drop me an email to remind me, when you want to see the numbers.

Note: I've got a psychic mail-server. The address on the postings _is_
valid, but it accepts mail *only* from inside a newsreader, in reply
to an article I posted. Amazingly effective at eliminating 'spam'. :)
The reject notice does provide a work-around, for those who need it, too.

Trying to get the torrent with no success. And I know it should work,
got Lineox Enterprise Linux with it recently.

Odd, and interesting! I had a similar report from someone else last
night.

On the other hand, I just went to the link myself, fetched the torrent
file, and my BitTorrent reference client launched itself and started a
download of the -ebook version with no problems at all.

What client are you using? Are you behind some sort of NAT gateway or
other firewall?

The tracker shows me three downloads in progress - my own (of the
-ebook) and two others (of the -printer). I'm getting about half of
the download bandwidth, though, so it may be that one of the transfers
is stalled for some reason.

TorrentStorm, behind a NAT, but that has never been an issue before.
