Re: [TUHS] "9 skills our grandkids won't have" - Is this a TUHS topic?

by Michael Kjörling

On 30 Jun 2022 23:14 +1000, from sjenkin(a)canb.auug.org.au (steve jenkin): > What are the 1970’s & 1980’s Computing / IT skills “our grandkids won’t have”? Tediously typing computer programs into their (or others') systems from listings in printed magazines bought in and brought home from a store (by which I mean the physical, brick-and-mortar kind), only to spend anywhere from minutes to days figuring out why the program doesn't do what the magazine says it will, if it even works at all. This thread should probably be on COFF, not TUHS. -- Michael Kjörling • https://michael.kjorling.se • michael(a)kjorling.se “Remember when, on the Internet, nobody cared that you were a dog?”

Status of classiccmp.org - take two

by Tomasz Rola

Alas, it seems like classiccmp.org is no good again. This time, when I open it, some dialog box pops up asking for a word. In the background below it, there seems to be something like a web panel... -- Regards, Tomasz Rola -- ** A C programmer asked whether computer had Buddha's nature. ** ** As the answer, master did "rm -rif" on the programmer's home ** ** directory.

Status of classiccmp.org?

by Warren Toomey

All, does anybody know the status of classiccmp.org? It's been down for a few days and I'm already missing the cctalk list. If it's a issue of hosting, and someone has Jay West's e-mail address, then I could host the list on minnie. I've just done the mailman3 upgrade with mailman2 running concurrently to provide old-school list archives. I'd be happy to give Jay access to the system. Cheers, Warren

A talk on the origin of Colossus

by David Barto

https://www.youtube.com/watch?v=WCeLTWPCEFI At about 45 minutes it is interesting history about early computing. The Computer History Museum has released 21 videos from a 1976 conference. https://computerhistory.org/playlists/international-research-conference-on-… I’ve only watched the one, and I’m sure the others are interesting as well.

Grep has gone overboard

by Dave Horsfall

I remember when the documentation was easy to read, but now... I'm trying to find a regex i.e. as used by GREP to find all words in "badugly" with each letter used only once and all are 7-letter words i.e. they are all anagrams; perhaps it's my age (I hit 70 soon, after decades in Unix) but I cannot seem to find a way to restrict the count i.e. each letter used only once, but in any order. I'll guess that it involves some obscure use of "{}*\" etc, which I've never really grokked... Ta muchly. -- Dave

Another COFF test e-mail

by Warren Toomey

All, I had someone ask if they had fallen off the COFF mailing list. So this is a test e-mail to ensure the COFF list is working OK. Cheers, Warren

Archives of the COFF mailing list

by Warren Toomey

All, now that the COFF list has migrated over to the new mailman3 system, I should point out where the list archives are now available. They are: https://minnie.tuhs.org/mailman3/hyperkitty/list/coff@tuhs.org/ - new mailman3 format https://minnie.tuhs.org/pipermail/coff/ - old mailman2 format https://www.tuhs.org/Archive/Documentation/COFF/Mail_list/ - same as above, but in a format that makes it easier to download All mail to the COFF list should, eventually, end up in all three places. Cheers, Warren

Oops, re hello to COFF

by Warren Toomey

All, if you got a strange 'hello' message on the COFF mailing list, my apologies. I have mailman3 set up on the new "minnie" machine, and I am going to also set up a mailman2 instance. The idea is that mailman3 will do the normal list processing and have its own archive using the Hyperkitty software. But mailman2 will be subscribed to the list, so mail can be also archived using the old pipermail software. That way, I can import the existing TUHS and COFF mailing list archives and augment them, rather than lose them entirely. I thought I'd deleted all the COFF subscribers on the new "minnie" system, but I can see in the logs that some test e-mail might have escaped. Cheers, Warren

Re: [COFF] [TUHS] conventions around zero padding in ip4

by jnc＠mercury.lcs.mit.edu

> [the TIU] was definitely one of the first 4 TCP implementations done There may have been some other early ones; see e.g. IEN-3 Jon Postel "Meeting Notes 15 August 1977". I was thinking of the TCP's which showed up for the first TCP Bakeoff, on 27 January, 1979. > From: Lars Brinkhoff > Any idea when the TENEX implementation was made? > These files seem to be from 1982: 1982? That's almost up to Linux time, in early internet time! :-) It's like 'dog years'; a year back then was an aeon! OK, to start with, a few 'definitions': TCP 2 - the earliest version that was really implemented much; no separate IP layer TCP 2.5 - basically the same as TCP 2 (packet formats, algorithms), but with things re-labelled into 'TCP' and 'IP' TCP 3 - variable length addresses (later discarded, sadly) (The archaeology in the IENs is a little complicated, because meeting notes aren't in temporal order, IEN-number-wise. E.g. the notes for the meeting on 2-4 August 1978 (the first one I went to, BTW) are IEN-53, which came out on 21-Aug-78; but the notes for the 14-15 July 1977 meeting are IEN-65, which came out on 5-Aug-78.) Anyway, about the first details about the TENEX TCP implementation (done by Bill Pluumer, whom we have now sadly lost) I could find are in IEN-67 ("Meeting Notes - 30 & 31 January 1978"): https://www.rfc-editor.org/ien/ien67.pdf where he reports that an implementation of TCP-2 (in the OS, not in a user process, as an early version was). In IEN-53 ("Meeting Notes - 2,3&4 August 1978"): https://www.rfc-editor.org/ien/ien53.pdf Action Items 6 and 7 refer to 6) the installation of presumably somewhat working TCP 2.5's at SRI, BBN and SRI, and 7) the installation of test version of TCP 4 at BBN. Finally, IEN-57: https://www.rfc-editor.org/ien/ien57.pdf by Bill Plummer, "Provisional TCP Development Plan" (for TENEX/TOPS-20 TCP) gives sime interesting details. Noel
