Happy birthday, Grace Hopper and J.F.Ossana!

by Dave Horsfall

Augusta Ada King-Noel, Countess of Lovelace (and daughter of Lord Byron), was born on this day in 1815; arguably the world's first computer programmer and a highly independent woman, she saw the potential in Charles Babbage's new-fangled invention. J.F.Ossanna was given unto us on this day in 1928; a prolific programmer, he not only had a hand in developing Unix but also gave us the ROFF series. Who'ld've thought that two computer greats would share the same birthday? -- Dave

Grace Hopper

by Dave Horsfall

We gained Rear Admiral Grace Hopper on this day in 1906; known as "Amazing Grace", she was a remarkable woman, both in computers and the Navy. She coined the term "debugging" when she extracted a moth from a set of relay contacts from a computer (the Harvard Mk I) and wrote "computer debugged" in the log, taping the deceased Lepidoptera in there as well. She was convinced that computers could be programmed in an English-like language and developed Flow-Matic, which in turn became, err, COBOL... She was posthumously awarded the Presidential Medal of Freedom in 2016 by Barack Obama. -- Dave

Re: [TUHS] C comments

by Doug McIlroy

Very little in language design is so contentious as comment conventions. C borrowed the PL/I convention, which had the virtue of being useful for both in-line and interlinear comments, and did not necessitate marking every line of a long comment. Nobody in the Unix lab had had much experience with the convention, despite having worked on Multics for which PL/I was the implementation language. And how did PL/I get the convention? It was proposed by Paul Rogoway at the first NPL (as it was then called) design-committee meeting that I attended. Apparently the topic had been debated for some while before and people were tired of the subject. Paul was more firmly committed to his new idea than others were to old options, so it carried more or less by default. Besides, there was a much more interesting topic on the agenda. Between the previous meeting and that one, George Radin had revamped the entire NPL proposal from mainly Fortran-like syntax to Algol-like. That was heady enough stuff to divert people's attention from comments. As for inexperiece. The comment conventions of previous languages had not fostered the practice of commenting out code. So that idea, which is the main impetus for nesting comments, was not in anybody's mind at the time. Had it been, nesting might well have carried the day. It probably could have been changed before 1980, but thereafter there were too many C compilers. Then standards introduced even more conservatism. Perhaps Ken can remember whether the notion was ever seriously considered. Doug

DEC compilers (was Happy birthday, John Backus!)

by Paul Winalski

Another DEC compiler that I forgot was the original C compiler for Tru64 Unix on the Alpha. This was done at the DECwest facility in Seattle (which originally had been set up by Dave Cutler). It was a very strict implementation of the ANSI C89 standard--it had no extensions such as K&R support. One customer called it the "Rush Limbaugh of C compilers" because it was extremely conservative and you couldn't argue with it. -Paul W.

Re: [TUHS] c's comment

by Richard Tobin

> Why can't c language comments be nested? For comments that really are comments, what would be the point? For comments that are really removal of code - commenting out - there is a better mechanism, #if (or #ifdef), which does nest. -- Richard -- The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336.

Re: [TUHS] Stories

by Doug McIlroy

> So how was it that so many smart - and somewhat like minded it seems > people end up there? [At Bell Labs] 1. Bell Labs had a great reputation, though it was not at first known for computing. 2. Research recruiters were researchers themselves, not HR people. 3. Recruiting was for quality hires, not for particular jobs; complementary talent was valued. 4. Whom a candidate met on site was determined after s/he gave a seminar; this promoted good matchups. 5. Researchers decided for themselves what to work on--either self- generated or an interesting problem from elsewhere in the company. 6. If you needed to know something in most any field, you could usually find a willing expert to get you on track to an answer. 7. Annual merit review was collegial. No one lost out because of unlucky draw of a supervisor. 8. Collegiality in fact beat that of any faculty I know. Office doors were always open; new arrivals needed only to do good work, not to chase tenure. This culture grew from the grand original idea of the Labs: R&D for the whole of AT&T funded by the whole of AT&T, with a long time horizon. I joined thinking the Labs was good seasoning for academia. The culture held me for 39 years. The premise was viable in the days of regulated monopoly. It has been greatly watered down since. Doug

stories

by Larry McVoy

Ken's story got me thinking about stuff I would still like to learn and his comment about "when I got to Bell Labs"... made me wonder how did Ken, Dennis, Brian, Joe and the rest of the crew make their way to Bell Labs? When I was just starting out, Sun was sort of the Bell Labs of the time (not that Sun was the same as Bell Labs but it was sort of the center of the Unix universe in my mind). So I wanted to go there and had to work at it a bit but I got there. Was Bell Labs in the 60's like that? If you were a geek was that the place to go? I was born in '62 so I don't have any memory of how well known the Labs were back then. So how was it that so many smart - and somewhat like minded it seems - people end up there? --lm
