{sigh} No, it's a deliberate list configuration. You're absolutely right that that particular list configuration is archaic and essentially never seen (otherwise) on a usable mailing list in this decade, because of the continually rising spam problem. TAG has always been set up to permit non-subscriber posting because of its unique intended role: It's supposed to permit any reader of _Linux Gazette_ to address the mailing list to converse with The Answer Gang. Doing so of course makes it very vulnerable to spam.
You will probably have noticed that some spam does get through my MTA and mailing list software defences. I (as listadmin and MTA owner) then manually analyse ASAP any spam that does so, and take immediate action to ensure that no further mail from that (pick one; whatever seems most effective and least disruptive of legitimate mail) SMTP HELO string, or sending address, or sending domain, or IP will be accepted in the future. That is of course a no-win strategy with unavoidable collateral damage, but it's the best I can contrive under the circumstances.
TAG is the only mailing list with that configuration I know that's not utterly overwhelmed with spam and thereby made useless, so I must be doing something right. But the possibility of it, too, getting overwhelmed is always present.

Tessboxes is a viewer/editor for tesseract boxfiles (used when creating training data for tesseract). http://www.lbreyer.com/tessboxes.html
On the topic of tesseract; there's also http://code.google.com/p/tesseractindic/ which is a version of tesseract adapted to Indian languages.
cuneiform-linux 0.5 was released recently, too; I'll see if I can find the announcement. It now supports hocr.
Mandrake v9.1 on a Dell CPi D300XT
EJB [ejb at intergate.com]
Wed, 19 Nov 2008 13:02:14 -0500
Folks;
Several years ago, on a whim while at an OfficMax store I came across a sale going on regarding Mandrake v7.0 Linux and dis-satisfaction with MS (and the lower sales price) gave me reason enough to purchase the Linux package ... from the view of an owner/operator of several units - best thing I think I ever did. Couldn't believe that Linux software went on as smoothly as it did - and it worked - well mostly it worked but it did it well enough for me to keep an eye on the Linux OS which were available.
Recently I pulled an old Dell Latitude CPi D330XT out of "storage", deciding to keep it as a back up and fully operational unit and once again I've come across an old problem, one I never did solve in the past.
What I have is the following:
. A Dell D300XT laptop with a 10GB HD and 256kRam
. Mandrake v9.1 Linux and MS 98SE for Operating Systems
With disk partitioning, I've set or better, limited the HD space to just 2GB, with Mandrake v9.1 getting the rest of the available HD space. Yes, it does work/fit and very nicely at that but ...
PROBLEM I: SOUND - how do you get Linux to recognize the built-in sound card/chip which is available with these old Dell machines? At present,there is no sound at all and there is little doubt here but that and for want of a better term, "it's there" and it's just a case of finding out how to activate it.
PROBLEM II: PPP - It's timing out. I can get the dialer to dial in to the ISP but there's no data flow going on and the PPP times out. How do I get this software to "click" and connect?
PROBLEM III: SCANNER - I have an old (but very reliable V300 Microtech scanner but I can't get the Linux software system to recognize that the scanner is there. Win98SE will recognize it and operate it and there's no doubt here but that Linux will do it to - if I find and "set all the switches" in the proper manner.
I'm open to any and all ideas and suggestions.
Thanks for your time an interset.

How to get a random file name from a directory
Suramya Tomar [security at suramya.com]
Tue, 25 Nov 2008 00:40:30 +0530
Hi Everyone,
I am working on a collage creation script in bash and am using find to get a list of all jpg files in a given directory. However find always returns the image names in the same order so the collage tends to have images from the same photo set i.e. at a given time it will have the most of the images from a particular subfolder.
What I want to do is get a list of random image file names from the system and then use it to create the collage, so that the collage looks more varied.
Here's what I have done so far to get a random file name:
awk "NR==$(($RANDOM % $(wc -l fi.txt| awk '{print $1}')))" fi.txt
where fi.txt was created using
find . -iname "*.jpg" -true | sed 's/ /\\ /g' >fi.txt
Now, this way works but I have to create a temp file which I want to avoid. Is there some way of getting find to return results in a random order? I tried searching the web but didn't find any useful results.
I am attaching the current version of the Collage creation script with this email to give you an idea of how it works. This version is without randomization of the filenames.
Thanks in advance for the help.
- Suramya
PS: Please do give your feedback/suggestions on how the script can be
improved in addition to a solution

adding key combination in inittab file
J.Bakshi [j.bakshi at icmail.net]
Sat, 1 Nov 2008 11:10:12 +0530
Hi list,
Hope you all are well.
I am trying to modify the /etc/inittab file to add more key combination. One of the reasons is to shut down the system. I have added this line in the inittab
~~~~~~~~~~~~~~~~~~~~~~~~~~~` #shut down wit ctrl+alt+end ce:12345:ctrlaltend:/sbin/halt ~~~~~~~~~~~~~~~~~~~~~~
but "init q" reports
:ctrlaltend: unknown action field
Could any one kindly point out my mistake ? I like to define some more key combination like ctrl+alt+< ; ctrl+alt+s etc to call commands. How can I define these key combination ?
Thanks

seeking suggestion about lftp
J.Bakshi [j.bakshi at icmail.net]
Sat, 22 Nov 2008 22:42:10 +0530
Hello,
Hope you all are well.
I have designed a script which compress some files and store those files in a folder named by date like 10-11-2008 ( for 10th Nov 2008 ) and uploads it in a remote ftp server through lftp. the script runs every day. As the FTP space is little after every 15 or so days the FTP space qouata is full. I like to include a section in the script which will check the folders in the ftp server through lftp and deletes the folders which already 10 days matured.
Can any one suggest me how to do this throug lftp ?
thanks a lot

LWN article: Wikipedia transition from GFDL to CC BY-SA

Of possible interest to LG in that it's another notable episode in the perennial "What's a good free licence for non-software content?" debate.

GFDL 1.3: Wikipedia's exit permit by Jonathan Corbet November 5, 2008
[...] Members of the Wikipedia project have wanted to move away from the GFDL for some time. [...] The presence of the "or any later version" language allows Wikipedia content to be distributed under the terms of later versions of the GFDL with no need to seek permission from individual contributors. Surprisingly, the Wikimedia Foundation has managed to get the Free Software Foundation to cooperate in the use of the "or any later version" permission to carry out an interesting legal hack. [...]
In other words, GFDL-licensed sites like Wikipedia have a special, nine-month window in which they can relicense their content to the Creative Commons attribution-sharealike license. This works because (1) moving to version 1.3 of the license is allowed under the "or any later version" terms, and (2) relicensing to CC-BY-SA is allowed by GFDL 1.3.
LWN articles become available to the general public after eight days, so non-subscribers will be able to read the story starting Nov. 13.

Patent lreversal on "business practice" patents
Ben Okopnik [ben at linuxgazette.net]
Sun, 9 Nov 2008 09:23:47 -0500
[Forwarded from the RISKS digest]
John Oram, Microsoft has a problem, *IT Examiner*, 31 Oct 2008
Much of the patent portfolio of some of the world's biggest software companies has become worthless overnight, thanks to a ruling yesterday by the US patent court.
The US Court of Appeals for the Federal Circuit (CAFC) in Washington DC has decided that in the future, instead of automatically granting a patent for a business practice, there will be a specific testing procedure to determine how patentable is that process.
The decision is a nearly complete reversal of the court's controversial State Street Bank judgment of 1998, which started the stampede for patenting business practices.

[OT] OpenLibrary 'scan-on-demand'
Jimmy O'Regan [joregan at gmail.com]
Tue, 4 Nov 2008 01:25:25 +0000
[Totally off-topic, but we all like to read, right?]
The OpenLibrary is a project from the Internet Archive; in short, they're building a Google Books-type catalogue of titles, integrated with the ability to search the text of those titles that have been made available through the Internet Archive. The coolest thing they have, though, is a 'scan on demand' feature for any book available at Boston Public Library -- if the book hasn't already been scanned, a librarian will put it in the scanner for you: http://openlibrary.org/bpl
