Thank you for bringing this up. I first posted to the list about the project in February 2013 [1], and some of you helpfully supplied me login names I was looking for. Over the past few weeks I managed to solve a difficult problem that was puzzling me, namely how to commit each release snapshot files incrementally, while also ensuring that git blame would work correctly across releases. Having solved the problem, I created a working repository with a some key releases in it, and was waiting to tidy up a few loose ends before coming to the list for more help. Now hat the cat is out of the bag, here are a few things I could need your help. 1. The login names of the following Bell Labs researchers Charles B. Haley E. Schmidt 2. The login names of the following Berkeley authors A. R. Newton Charles Haley Colin L. Mc Master Douglas Lanam D. O. Pederson Ellis Cohen Earl T. Cohen Ivan Maltz Juan Porcar Jeff Schriebman Kurt Shoens Len Edmondson Olivier Roubine R. Dowell Ross Harvey Richard Tuck Robert Toxen Susan L. Graham Zhishun Alex Liu 3. The names corresponding to the following Berkeley ids claudio csvaf denise ecc epg evan fitz fortran harrison lam opcode orange rt 4. The authors of a few relatively large contributions (the numbers are the changed lines associated with the specific release and corresponding total lines).

What code?

Charles Haley

chuck (per 1BSD's winfo, sh.1, cpall.6, where.6, whoison.6)

Douglas Lanam

What code?

D. O. Pederson

Real name is probably "Donald". But what code?

Ellis Cohen

cohen (per 1BSD's where.6 ; I don't think is Earl)

Juan Porcar

What specific code file for Juan Porcar?

Jeff Schriebman

jeff (per 1BSD's winfo)

Kurt Shoens

kurt (per 1BSD's winfo, mvall.6, whoison.6)

R. Dowell

Richard "Dick" Dowell of Hewlett Packard.

Ross Harvey

UCSF Computer Graphics Laboratory

Richard Tuck

tuck (per 2BSD netintro.n)

3. The names corresponding to the following Berkeley ids claudio

The login "dlw" included DLW as part of SCCS commit messages. The claudio entry also says "DLW". So probably David L. Wasley.

csvaf

Alastair Fyfe

denise

Denise Draper

ecc

Eric C. Cooper (login name also is "cooper" later)

epg evan fitz

Dan Fitzpatrick

fortran

I don't see this one.

harrison

Mike Harrison or Susan Graham Harrison (except I don't know timing for that name).

lam

Karen Lam of BBN

opcode

Mark Opperman

orange

Carol Orange

rt

I also don't find "rt"

1BSD pcs 1800 1800

One of the files says "Wirth" and note that other files have spellings like "funktion", "prozedure", "konstant". So maybe all this is from Wirth?

portlib 1701 1781

I think this portlib is from Eric Allman.

opcodes 1580 1580

I guess Thompson, Haley or Joy.

3BSD

I assume you are refering to parts not from 32V...

usr/src/sys/sys 8163 16488

I guess Babaoglu, maybe Juan Porcar, and Joy. Note that the TODO mentions code given to Joy.

usr/src/cmd/f77 5981 17252

I think some of the improvements came from the upstream (November 1978 1.16 vs. January 1980's 2.00).

usr/src/new/libI77uc 4379 5395

Files say originally P. Weinberger and modified by David Wasley.

usr/src/cmd/versatec 3885 4271

sidebyside was written by Joy (per Len Edmondson personal correspondence).

usr/games/advfiles/cave 1772 1772

It was common that some source for games weren't included. Says originally developed by Willie Crowther and most features added by Don Woods (don @ su-ai). And the file says to ask "ark" for questions. I think was in a group called MHTSA (but I don't kno what means).

usr/src/cmd/uucp 1358 7387

Maybe Dave Nowitz?

usr/src/sys/stand 1350 3382

Some of this is just from 32V. I can only guess the changes were from Joy.

usr/src/games/banner.c 1129 1129

Very interesting. Does your research extend into Sun? Because wnj went there and SunOS (not that Solaris stuff) was a "better BSD than BSD". mmap, vnodes, lots of very cool OS stuff happened at Sun that did not happen at Berkeley. No disrespect to Berkeley, they got the ball rolling, in some ways they were the Linux of the day, moving stuff forward while the rest of the world stalled. What was that Ken quote? Something about cat went to Berkeley and came back waving tails? Something like that? Whatever, I've been part of Unix dev for a long time and I'm painfully aware of the pushback that happens when people want to make things better. Berkeley made Unix better. Sun made it hugely better in my opinion. I was there at the tail end, you don't want to talk to me, you want to talk to wnj, rusty, moran, srk. They did some cool stuff. -- --- Larry McVoy lm at mcvoy.com http://www.mcvoy.com/lm
