weekly "Tcl-URL!" summary each Monday morning to a list of
subscribers. That's working out fine, I believe (although
they're generally a quiet, very business-like group, with little
to say).
Here's the bad news: my ISP is having weird, annoying NetNews
outages. For example, I posted article
<6rrdd3$66c$1...@Starbase.NeoSoft.COM> in a timely fashion on Monday
morning, but it appears to have been swallowed up somewhere along
the way to the outside world. I apologize to c.l.t for this; as
a *reader* of "README: Tcl-URL!", I know that a significant part
of its value lies in being able to count on it. Apparently that
won't be possible for a while.
So:
1. A copy of this week's edition follows below.
2. A few words on subscribing for e-mail delivery
appear at the tail of this message.
3. I'm working with my ISP to solve the problem.
4. Does anyone know of a conveniently automatable
way to inject a posting into the Usenet cloud?
I've never looked for one, as I assumed the em-
phasis at DejaNews et al. would be on filtering
out spam, not on facilitating legitimate peri-
odic postings.

If you have access to an NNTP server allowing postings, talking NNTP to
it amounts to a couple of "puts" (see the RFC, it's readable :).
My naive belief was that there were *public* ones around; tell me if I'm
wrong.

I tried the following to use Tcl's http package to post to DejaNews's
web postings page, but it doesn't seem to work successfully -- it
returns a "welcome to DejaNews" of the "your posting will show
up in a couple hours" that I'd usually expect. I'll have to do
some snooping and see if I can see exactly what POST variables I'm
missing. In the meantime, here's the script that will try to
post to alt.test from a "posting.txt" file:

UPDATE UPDATE UPDATE UPDATE UPDATE UPDATE UPDATE UPDATE UPDATE
I think I found a way to automate posting a file via DejaNews.
It requires a valid ~/.netscape/cookies file that has a recent
update (looks like there's some timestamp to expire the
.dejanews.com...DNREG cookie).
You'll want to set up the stuff down in the CONFIGURATION
PARAMETERS section. You also may want to add some form of
error checking...

set subject [lindex $argv 1]

set outfile [lindex $argv 3]

There are at least 4 Tk based NNTP clients listed in
<URL:http://www.teraform.com/%7Elvirden/tcl-faq/part4.html>. It seems like
one could take out the NNTP portions of these and turn it into an extension.
Or just look at Pnews from trn and convert it from shell into tcl...

The topic of GUI builders vs. programmatic interface
construction fascinates me, particularly when informed
by concrete examples and experiments. That's what
Scott Raney, Bryan Oakley, Donal K. Fellow, and several
others contribute in threads most cogently summarized
in
http://x7.dejanews.com/getdoc.xp?AN=383106025
http://x8.dejanews.com/getdoc.xp?AN=384877188
Of course, with Tcl one can have *both* GUI building and
textual rendering ...
"library" is wickedly polysemous, and a particular trial
for those just beginning programming. Larry Virden method-
ically lays out the key concepts in

One suggestion if you're going to continue to post to
newsgroup(s) in addition to distributing via email:
vary the "Subject" header by inserting a date.
Rationale: some users (like me) use a threaded
newsreader and archive infrequently. With no
"Subject" variations, new issues become threaded
with old ones. Since I don't scan the whole list of
headers each day, I was missing most of the issues
of RT-U.
How does that sound to others?

To me it sounds wrong. AFAIK a threaded newsreader isn't simply sorting
by subject, but rather using msg-IDs according to the References-Header.

'Would be sensible, wouldn't it? I have good
evidence that there are readers with every
combination of threading algorithm suggested
by our little scheme: no threading; threading
by ID; threading by subject; and threading by
*both* ID and subject (always with that prece-
dence?). Perhaps a Usenet wiz can detail the
realities.
