Unix 50 event at BTL Murray Hill?

by Dan Cross

This just came over another list, and I'm surprised not to have seen anything about it here. Anyone heard about it? https://tech.slashdot.org/story/19/10/12/1625237/bell-labs-plans-big-50th-a… - Dan C.

Fwd: Curious Question from the Ether about use of Upper and Lower case at DEC

by Clem cole

FYI. I sent this to one of the lead DOC people from the old days to see if she knew. Here is her answer. Begin forwarded message: > From: "Janet Egan" > Date: October 11, 2019 at 7:53:16 PM EDT > To: "'Clem Cole'" > Subject: RE: Curious Question from the Ether about use of Upper and Lower case at DEC > > Hi Clem, > > Hmm, I don’t remember whether the style guide addressed that. In the docs for RSX-11M and such I always wrote it “PDP-11”, that is upper case with the dash. I do remember the logo on the machine as always lower case with no dash. The PDP-8 had the same style logo. And you’re right about seeing the lower case on the cover of the handbooks. I have never seen the lower case with the dash or the upper case without it. I don’t think I still have my copy of the style guide. Maybe I’ll take a look around my archives for it. > > What a fun question to be thinking about . > Janet > > > From: Clem Cole > Sent: Friday, October 11, 2019 9:47 AM > To: Janet Egan > Subject: Curious Question from the Ether about use of Upper and Lower case at DEC > > Janet, > I'm part of The Unix Historical Society (TUHS) mailing list and a topic came up that I thought you might be able to shed some light on. The observation was that 'DEC seemed to have a schizophrenic attitude to wrt to use of upper and lower case WRT to the PDP-11 brand,' i.e. sometimes using "PDP-11" and sometimes "pdp11" (but I note rarely if ever PDP11 or pdp-11) . For instance, the logo on the system itself was all lower: PDP-11/40 but DEC documentation mostly used uppercase in the text; but when used on the places like the cover could be either e.g. the "pdp11 peripherals handbook" to transcribe the cover exactly but it uses upper case "PDP-11" several times on pg 1-1 and the same on the binding. But I could not find examples of pdp-11 or PDP11, i.e. if all lower it was with the dash or all upper without. > > Do you remember if there were rules or guidelines and if so what they might have been? > > Thanks, > Clem

Awk for CSV files

by Richard Tobin

I was reminded of this by Larry's comment: > I miss Brian on this list. I've interacted with him over the years, the > one I remember the most was I was trying to do an awk like interface to a > key/value "database". Recently I've had to deal with a lot of data in CSV (comma-separated-value) format. Awk is *almost* prefect for this, but of course doesn't handle the quoting of fields that contain commas. One can usually work around it by finding a character that doesn't occur in the data and converting the CSV file to use that as the separator, but it's not ideal. Awk's input could easily be modified to handle CSV files, but output would be a bit more difficult, because you don't specify field boundaries explicitly on output. One possibility would be a printf() format specifier that takes a field and quotes it appropriately. -- Richard -- The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336.

Re: [TUHS] What was your "Aha, Unix!" moment?

by jnc＠mercury.lcs.mit.edu

> From: Arnold Skeeve > K&R was so dense that my head was swimming after the first read. I learned C from "Programming in C - A Tutorial", by Brian Kernighan, which for some reason seemed to have fallen into desuetude from V7 on (at least, that was the impression I got). Which was a pity, it was one of the best documents I ever read - a breeze to read through, and clear as crystal. Noel

Re: [TUHS] What was your "Aha, Unix!" moment?

by Rudi Blom

Not sure I had an "aha erlebnis" with UNIX. I'd done some testing on a Philips PTS6000 with T.O.S. All assembler code with debugging syslod the most fun (breakpointing code which moves itself in memory). Then I was a user on VAX 11/730, 11/750 with Ultrix which was a bit of a step down. The VAXes run VMS during the week and only in weekends we could place our disk pack and boot Ultrix. Funny feeling to go home when colleagues arrive in the morning. Later "Propriety UNIX" versions based on System III, 7, V. No source. Still had shells, command line, scripts, a bit of programming in C if all else fails (or is too slow). Never liked Windows. In that sense maybe more an 'aha windows' moment to quickly forget :-) Cheers, uncle rubl

Re: [TUHS] What was your "Aha, Unix!" moment?

by Jon Steinhart

Well, I guess mine is kinda weird. I had messed with a number of computer systems a litle bit and then became proficient with 516-TSS as a result of being part of the explorer scout post at BTL Murray Hill in high school. Interesting note is that one of my advisors who wrote a lot of 516-TSS interviewed Ken for his job at BTL. Ended up with a paid job at BTL starting near the end of my senior year of high school. Needed to document my work. Don't remember why, but my group acquired a PDP-11/40 that was across the hall from the 516 lab in building 2 that was running UNIX version 3. I started using roff on it to do my documentation which meant learning ed and a bunch of other tools. Of course, I took the manual home and read it cover to cover and started messing around with the various cool tools that it had and was hooked. Jon

Re: [TUHS] What was your "Aha, Unix!" moment?

by jnc＠mercury.lcs.mit.edu

> From: Warren Toomey > What was your "ahah" moment when you first saw that Unix was special, > especially compared to the systems you'd previously used? Sometime in my undergrad sophmore year, IIRC. A friend had a undergrad research thing with DSSR, who I think at that point had the first UNIX at MIT. He showed me the system, and wrote a tiny command in C, compiled it, and executed the binary from the shell. No big deal, right? Well, at that point ('75 or so), the only OS's I had used were RSTS-11, a batch system running on an Interdata (programs were submitted on card decks), the DELPHI system (done by the people in DSSR), and a few similar things. I had never used a system where an ordinary user could 'add' a command to the command interpreter, and was blown away. (At that point in time, not many OS's could do that.) Unix was in a whole different world compared to contemporaneous PDP-11 OS's. It felt like a 'mainframe' OS (background jobs, etc), but on a mini. Noel

Re: [TUHS] What was your "Aha, Unix!" moment?

by Doug McIlroy

For a contrast in aha moments, consider this introduction to an early Apple (Apple II, I think). When my wife got one, my natural curiosity led me to try to make "Hello world". I asked her what to use as an editor and learned it all depends on what you're editing. So I looked in the manual. First thing you do to make a C program is to set up a "project", as if it was a corporate undertaking. I found it easier to write a program in some other editor than the one for C. Bad idea. Every file had a type and that editor produced files of some type other than C program. After succumbing to the Apple straitjacket, I succeeded. Then I found "Hello world" given as an example in the manual. The code took up almost a page; real men make programs that set up their own windows. Aha, Apple! Not intended for programmers. And that didn't change until OS X. Doug

bwk

by Larry McVoy

I miss Brian on this list. I've interacted with him over the years, the one I remember the most was I was trying to do an awk like interface to a key/value "database". I talked to him about it and he sent me ~bwk/awk which had all the original awk source and the troff source to the awk book in english and french. Ken, Doug, Rob, Steve, anyone, could you coax him onto this list? If you want me to try first I will, I don't know if he remembers me or not. But I can try and then maybe one of you follow up?

Welcome to new TUHS subscribers

by Warren Toomey

All, we just had about a dozen new subscribers to the TUHS list. Rather than e-mail you all individually, I thought I'd use the list itself to say "Welcome!". The TUHS list generally has a high signal/noise ratio on the history of Unix, the systems and software, and anecdotes from those who used the various flavours. Occasionally, we drift a bit off-topic and I'll gently nudge the conversation back to Unix history. The list archives are at: https://minnie.tuhs.org/pipermail/tuhs/ and you should browse the last couple of months to get a feel for what we talk about. Cheers, Warren

My case for video footage of the machine Ken would later use to create Unix

by Warner Losh

https://bsdimp.blogspot.com/2019/10/video-footage-of-first-pdp-7-to-run-uni… is a blog entry where I step through the evidence that the PDP-7 in The Incredible Machine video that was posted here a while ago is quite likely the PDP-7 Ken used to create Unix after its days of starting in Bell Labs films were over...

Old Unix and DWB manuals seeking scanning and a permanent home

by Rich Kulawiec

I've lugged these around for 35-ish years. I'd like to seem them scanned and stored someplace as permanent as can be found, so if someone/anyone could tell me how to facilitate that, I'll package them for shipping. My apologies if this has already been done and I'm simply not aware of it. I have other stuff that probably needs the same treatment, but excavating the alluvial layers that have accumulated will take time.

where are v7 manual scans? license details?

by reed＠reedmedia.net

I am surprised to not find any scans of early (pre-1980) Seventh Edition Unix Programmer's Manual. Does anyone have any? (We do have the source files and I see volume 2 manual scanned from later years.) Also where is a copy the new license introduced with v7? I have copy of 1973 and 1974. Anyone have a scanned later version? from etc/rc: echo "Restricted rights: Use, duplication, or disclosure is subject to restrictions stated in your contract with Western Electric Company, Inc." >/dev/console Thanks, Jeremy C.

History talk in Dallas Texas October 10

by reed＠reedmedia.net

The Dallas Ft. Worth UNIX Users Group will be highlighting the 50th anniversary on October 10, November 14, and maybe in December. http://www.dfwuug.org/wiki/Main/Welcome I will be presenting about the early history next week and then about BSD-specific history in November. Any of you in the DFW area? Any suggestions on anyone local to invite? I am also looking for anyone local who can display old hardware or materials at the event. I only have some old books and training materials from 1980's. Does anyone have scanned copies of early Lions commentary? (Not the 2000 printing, unless it looks identical, please let me know.) I will try to share my slides to this list by end of this week. (I did look at an early draft of Warner's slides, but didn't look at his final slides nor watch his presentation yet. My presentation is from scratch for now.) Jeremy C. Reed echo Ohl zl obbx uggc://errqzrqvn.arg/obbxf/csfrafr/ | \ tr "Onoqrsuvxzabcefghl" "Babdefhikmnoprstuy"

Recovered /etc/passwd files

by Finn O'Leary

Hi, I remember that someone had recovered some ancient /etc/passwd files and had decrypted(?) them, and I remember reading that either ken or dmr's password was something interesting like './,..,/' (it was entirely punctuation characters, was around three different characters in total, and was pretty damn short). I've tried to find this since, as a friend was interested in it, and I cannot for the life of me find it! Do any of you remember or have a link? :) Thanks! -- "Too enough is always not much!"

My EuroBSDcon talk (preview for commentary)

by Warner Losh

OK. I've shared my slides for the talk. Some of the family trees are simplified (V7 doesn't have room for all its ports, for example) Some of it is a little cheeseball since I'm also trying to be witty and entertaining (we'll see how that goes). Please don't share them around until after my talk on the September 20th I'd like feedback on the bits I got wrong. Or left out. Or if you're in this and don't want to be, etc. All the slides after the Questions slide won't be presented and will likely be deleted. https://docs.google.com/presentation/d/177KxOif5oHARyIdZHDq-OO67_GVtMkzIAlD… Please be kind (but if it sucks, please do tell). I've turned on commenting on the slides. Probably best if you comment there. I have a video of me giving this talk, but it's too rough to share... Thanks for any help you can give me. Warner

eqn

by Larry McVoy

So my kid is using LaTex and I'd like to show him what troff can do. For the record, back when he was born, 20 years ago, I was program chair for Linux Expo (which sounds like a big deal but all it meant was I had the job of formatting the proceedings). LaTex was a big deal but I pushed people towards troff and the few people that took the push came back and said "holy crap is this easy". My kid is a math guy, does anyone have some eqn input and output that they can share? Thanks, --lm
