Well, will have to play with this awhile... never attempted to use
finereader with existing scans... and not having much luck working something
out--I expected it to be more straight-forward...

Warmest regards,
John

The original scans are 300 dpi grayscale, PGM (portable graymap)
format. Easily translated to TIFF.

The data in the PDF itself is 300 dpi one-bit-deep black&white data,
compressed... converted from the grayscale data via thresholding.

Dave:

Are you familiar with microsoft reader... it reads ebooks in something of a
"paperback style." I am not sure if there is a counterpart in the Linux
world... are you dual boot?

Warmest regards,
John

I've got reasonable bandwidth resources, so I've put up the 'printer'
version as a straight PDF download, for those who don't have bittorrent
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!

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.

The documentation at BitTorrent.com points out that downloads may not
work, or may be quite slow, if you're behind a NAT and don't arrange
for port forwarding of inbound connections from your peers. In this
situation, you can end up being unable to exchange data with some or
all of the peer sites you try to connect with.

As I understand it, this shouldn't affect the seeder I'm running,
since it already has a complete copy of the file and doesn't insist on
a tit-for-tat exchange of data. However, it's possible that there may
still be some issues, with some NATs or firewalls.

Both my tracker, and my seeder clients, use the BitTorrent 4.01
reference implementation, and neither is behind a NAT. I've been able
to transfer successfully from a system here at work which *is* behind
a NAT, and the transfer went quite efficiently. So, it's possible
that the problem lies at your end, although that's not a certainty.

My system _does_ react rather strongly, in defense, against systems
which appear to be trying to port-scan it for vulnerabilities or
trojans... it'll slap down a hard IP filter against such systems and
will appear to "vanish" from the net.
