Today's tape recovery gem. UBC's PDP-11 UNIX tools distribution ca. 1983 which includes UBC BASIC and their RT-11
emulation. It has a couple of bad blocks, but I couldn't find another copy of this anywhere.
http://bitsavers.org/bits/UBC/
If anyone has a complete copy, it would be good to replace it, but most is better than none of it.
All, I've locked the "Women in Computing" topic in the TUHS list
as it's not specifically Unix and liable to be contentious. Feel free
to continue it over on the COFF list.
E-mail me if you'd like to join the COFF list.
Cheers, Warren

Interesting. Any ideas/thoughts on what was going on, what caused that?

Unless my leg is being pulled, I sent that for pure amusement.
Gcc has a very open mind on the subject, using both options
in the same sentence.

My impression was Doug was passing on a warning about the continued used
of mktemp(3) rather than the continued use of ASCII.

Can people _please_ pick either one list _or_ the other to reply to, so those
on both will stop getting two copies of every message? My mailbox is exploding!

I'm not sure this part is accurate: the two efforts were contemporaneous; and
my impression was they were trying to design the next step in networking, based
on _their own_ analysis of what was needed.

This is I think true, but then again, TCP/IP fell into some of those holes
too: fragmentation for one (although the issue there was unforseen problems in
doing it, not so much in it not being a real issue), all the 'unused' fields
in the IP and TCP headers for things that never got really got
used/implemented (Type of Service, Urgent, etc).

Ah, sorry, I misunderstood your point.
Anyway, this is getting a little far afield for TUHS, so at some point it
would be better to move to the 'internet-history' list if you want to explore
it in depth. But a few more...

I assume you mean 'systems running TCP/IP'? If so, I really don't know,
because for a while during that approximate period one saw many internets
which weren't connected to the Internet. (Which is why the capitalization is
important, the ill-educated morons at the AP, etc notwithstanding.) I have no
good overall sense of that community, just anecdotal (plural is not 'data').
For the ones which _were_ connected to the Internet, then prior to the advent
of the DNS, inspection of the host table file(s) would give a census. After that,
I'm not sure - I seem to recall someone did some work on a census of Internet
machines, but I forget who/were.
If you meant 'systems in general' or 'systems with networking of some sort', alas
I have even less of an idea! :-)

Well, not quite - X.25 was also available on just about everything. TCP/IP's
big advantage over X.25 was that it worked well with LAN's, whereas X.25 was
pretty specific to WAN's.
Although the wide range of TCP/IP implementations available, as well as the
multi-vendor support, and its not being tied to any one vendor, was a big
help. (Remember, I said the "_principle_ reason for TCP/IP's success"
[emphasis added] was the size of the community - other factors, such as these,
did play a role.)
The wide range of implementations was in part a result of DARPA's early
switch-over - every machine out there that was connected to the early Internet
(in the 80s) had to get a TCP/IP, and DARPA paid for a lot of them (e.g. the
BBN one for VAX Unix that Berkeley took on). The TOPS-20 one came from that
source, a whole bunch of others (many now extinct, but...). MIT did one for
MS-DOS as soon as the IBM PC came out (1981), and that spun off to a business
(FTP Software) that was quite successful for a while (Windows 95 was, IIRC,
the first uSloth product with TCP/IP built in). Etc, etc.
