Gene Spafford made a couple of files of old mail available to
the list.  One file is a set of mail messages from a mailist
on UsenetII from 1985.  They make for interesting reading in
light of the changes that have happened since the discussion
took place.

Gene's intro message has also given rise to some thought about
what this mailist is all about as well.  More on that later.

The other file is called "rename" and it shows some of the very
early discussions about The Great Renaming, a subject near and dear
to all of us around here at present.

The files are in the ftp login directory I mentioned yesterday. Drop
by and take a look.

vax135 was definitely an early player (there were very good relations
between the vax135 folks who put out UNIX/32V and the ucbvax folks who
got the first beta tape) and I could believe that the Netnews link was
duke<->vax135<->ucbvax.  But the email link was definitely via research.

Somewhere I have on magtape a map or two from the spring of 1981,
back when there were only 30 or so machines on the net.

The oldest map I have (paper, 1/1/82) shows research as a leaf, vax135
as a minor hub (links to cornell, ihnss and harpo.)  This map shows every
machine that got Netnews one one sheet and was only photo-reduced from
about 11x17.

I do have a 9/21/81 map made by Phil Karn, Mr. ihnss (forerunner of ihnp4),
which is not entirely accurate for the time.  It shows chico, ihnss, and
mhtsa as the major hubs, with chico migrating into harpo.

The backbone is first mentioned in the
July 1983 map - it was not mentioned on the Jan 1983 map.
In July 1983 there were both logical maps (showing all hosts) and
geographic maps (showing the biggest host in each city on a US map.)

We did a geographic map only in 1/84, and in 6/84 the only map was a
machine-readable 4 page logical map done by Bill and Karen Shannon -
I had given up on trying to show it on paper, and did the last geographic
map in 6/84.  Bill and Karen continued to put out their machine readable
one on the net periodically.  Now, of course, Brian Reid puts out his
Postscript stuff.

The first links to Canada appeared on the 1/1/82 map (watmath, utzoo,
and 2 machines behind each.)  In 1/83 philabs bridged the atlantic
to connect to mcvax, dutesta, and ukc.  By 7/83 a second link from
ukc to vax135 (non-backbone) existed, and a link from sdchema in San
Diego to basservax in Australia (by magtape once a week!) appeared.

I have this stuff on paper, and can send it to one person who is the
keeper of all this.

There were two "backbones" -- the physical backbone, and the
"political" backbone.   Mark was indeed the ancestor of the physical
backbone, and I was the originator of the "political" (i.e.,
decision-making) backbone.  I guess my earlier mail didn't make that
distinction clear.

Enclosed are some machine-readable maps I got from either Mark or
Steve Bellovin.  Once, when my life was considerably simpler than it
is now, I volunteered to help write a definitive history paper on the
Usenet.  Mark & Steve had both started this paper, but had other
things come up.  I started revisions, lost them in a machine crash,
redid some of them, then had the tide of events sweep away whatever
free time I had available to work on it.  I may get back to it
someday, but not this week. :-)

Anyhow:

Subject: Early Usenet info

Cyrus Rahman, Duke physics grad student,
recently sent me some early Usenet data
on the disks of the old Duke CS PDP 11/70.
(Physics dept. -- where old computers go to die.)

I am including two interesting files.
The first describes the 'duke' site on Mar 11 1981,
the other is a collection of interesting early net articles.
Amongst the articles is the announcement of decvax.
One interesting thing about those articles is their brevity--
some are only two lines long.
Of course, this was probably a sample of only
the most interesting/useful articles.

Also on the tape was a Usenet Invitation paper,
not the original but fairly old (Mar 1981) .
You have probably seen this excerpt, but in case you haven't:
QUESTIONS ANSWERED
IP 1.
Isn't this expensive?
br
Not at all.
Night time phone costs are about $0.50/3 minutes,
in which time uucp can transfer about 3000 bytes of data (300 baud).
Daily polling then costs $15/Month, which is half what Duke pays
just for an office phone.
IP 2.
Can Duke really handle all the phone calls?
br
Sure.  We have two call-out lines: at five minutes/call,
we can handle 24 calls/hour.
Other systems can also perform the call-out function.
Remember this when reading the decvax article.

ac-bugs             : NET.general
"ac" as distributed with V7 has several problems.
1) General terminal names are not supported. All terminals
  except the console must be named "ttynn". This causes
  serious accounting problems as logins on all other terminals
  are mapped into the console.
2) Ac looks for "}" to indicate a new date instead of the
  correct "{".
3) "Midnight" (-d option) is not always computed correctly.
4) Diagnostic messages are incomplete.

       Duke has rewritten ac and fixed these problems.
The new version is available from "duke!~uucp/duke/cmd/ac.c".

Floating-point bug in V7 Unix: NET.general
J. W. Stevenson of Vrije Universiteit in Amsterdam has
discovered and diagnosed a most interesting bug in
V7 Unix.  The problem is that the floating-point registers and
status are sometimes not saved across memory expansion via
sbreak() or stack growth or (less importantly) forks.
The problem only occurs when a swap is needed to
accomplish the expansion.

What happens is that the swap output IO is begun,
and then the registers are saved when the process
calls swtch() from sleep().
It is possible for the image to be written out before
the saving of the registers.

For reasons I do not fully understand situations can
occur in which the bug manifests itself consistently.
It seems to me that the register-saving should be finished
within a few hundred microseconds at most after initiation of IO
while the actual transfer (with ordinary moving-head disks)
will not begin for several milliseconds at least.
Nevertheless we have demonstrated the bug quite consistently;
by the usual sort of coincidence,
one of our machines began showing floating-point problems
the very same week that Stevenson's letter arrived.
(If the controller prefetches a significant amount of
data or if the disk is very fast then the consistency is not
surprising.)

At any rate, as suggested by Stevenson, the problem can be
fixed by adding the following code

       if (u.u_fpsaved == 0) {
               savfp(&u.u_fps);
               u.u_fpsaved = 1;
       }

to the following places in sys/slp.c:

before original line 507, "a2 = malloc(coremap, n);", in newproc();

and, after original line 564, "if(a2 == NULL) {", in expand().

uux bug             : NET.v7bugs
A bug in uux prevents the - option from working with binary files.
To fix it, in uux.c, search for "fputs".  (It's in an if (pipein) {.)
replace the fgets/fputs loop by
               while ((c = getc(stdin)) != EOF)
                       putc(c, fpd);
and declare c somewhere to be an int.  (I put the line
               register int c;
right after the if (pipein).)

Fixing this bug will allow the new uusend program, which will be released
shortly, to work, allowing the transfer of binary files across indirect
uucp links.

col                 : NET.v7bugs
The buffer-flush bug in col(1) that was mentioned in previous news
is due to using an automatic (local) variable for buffering stdout:
       char fbuff[BUFSIZ];
should be changed to
       static char fbuff[BUFSIZ];
(exit() also works since main() will not return before flushing.)
Col(1) is just one of several V7 programs with this flaw.

In the Duke version of stdio one can bypass the problem with
       setbuf(stdout, SYSBUF);
where SYSBUF is a flag indicating buffering is desired.

This is news to me.  At some point I handed off the backbone to Spaf
to keep an official list and ceased to worry about it myself.  I don't
think there were ever two separate backbones.  (Of course, the proposals
I made for a jawbone and funnybone notwithstanding.)

The two backbones were the same, after a while, but I was the one who
started using the the "backbone" as a group to talk about naming,

I guess I'm not explaining this very well....or maybe our

       Gene did not say "2 separate" ... I guess what it all means is
       that wereas you were "physical" (had a spine?  banged your head
       against the wall? :-)  Gene turned it into a political exercise
       (no backbone?)... thus 2 "kind of" backbones existed, one after

Bruce Jones suggested I might want to join this, and pointed me at the

>        (BT) Net goes international (Canada) (Spencer, Templeton)

Actually, if we are being picky, the first (I think) international Usenet
site was a machine whose name I can't even remember:  the Unix system that
Ron Gomes ran at BNR Ottawa.  The reason you've never heard of it is that
I don't think anything was ever posted from it; it was a read-only system
for all practical purposes.  It faded and died later, when Ron left BNR.
Utzoo was second by a couple of months.  I can date that quite precisely
if people are interested:  I've still got our archive tapes.

Yup, I was there, although I don't think I said much.

> Here is some old mail about renaming the mod groups to mainstream.

Incidentally, a major reason offered at the time for merging the "mod"
and mainstream name spaces was that it would make it easier for other
groups to "go moderated", something that was expected to be frequent.
I was against the merger and predicted that "going moderated" would
essentially never happen.  I think I can claim victory on this one.

An interesting side note on this is that almost everyone agreed that
talk.suicide -- whatever it was called in its previous life -- was dumb
and should go away during the renaming... but it was known to be the
plaything of people who were considered dangerous if hassled, so leaving

Actually, this is a good example of Natalie's Law, which Ron N. enunciated
for us in Atlanta when we were scheduling the Great Renaming:  "never set
major cutover dates on or near major holidays".  You want to make big
changes when everybody's at work, ready to deal with the consequences.
So the original schedule, which proposed change days on July 1 (Canadian
holiday, and too close to the US holiday) and Sept 1 (right in the middle
of the World Science Fiction Convention) was delayed two weeks.

San Diego, 1983.  Here's what my old notes say about it:

       Speaking of Usenet bills, \fIdecvax\fR's phone bill last year
       was $250\|000!
       They average 13 hours a day of long-distance calls.
       The main problem was characterized as ``Armando is too soft-hearted
       about letting new sites connect...''.

I can't complain too much, since we were among said sites... initially
with manual dialing at 300 baud!  These soft youngsters :-) have no
concept of the joy with which we greeted our first 1200-baud modem --
it had an **AUTODIALER**.  By common consent, getting it installed and
working took priority over everything else...

I can't remember this either.  utzoo appears on the 1/1/82 map along with
watmath and both look well established, but they aren't on the 6/81 map.

By the way, the 7/82 map does indeed show the backbone (with heavy lines),
I just missed it before.

It's certainly possible that Spaf and I had different ideas about what was
going on with the backbone.  Perhaps he felt he was creating something
else from scratch.  I remember telling people who asked what the
responsibilities of a backbone host were, and I gave them the usual set
about 2-3 links to other backbone sites (if possible), responsive SA,
latest software, able to fund the link, etc.  Then I remember Spaf adding
people to the list who met these criterea, and feeling surprised.  Perhaps
he considered it a separate backbone, but I thought it was the same one.
In any case, I didn't see any problem and I considered the backbone to
be in his hands from then on.

Look more closely:  utzoo is on the 1 June 1981 map.  (Copy on request.)
My records say we joined the net on 13 May 1981.  I think that is the date
of our new-site posting, although I'd have to dig in the archive tapes
to be sure of that.  The oldest article I have handy -- my report on the
V7 ldiv/lrem bug -- is dated 21 May.

I'm certainly willing to have utzoo considered the first international
site; just thought I'd mention that the BNR site has a weak claim on
the title.  Its feed, like our initial one, was from duke.  If anyone
cares, I can probably dig up date and site name.  Given that it never
announced itself and never posted anything, one could argue about whether
it really counts.

So it is - connected to duke, not decvax as I'd originally thought.
My mistake.
