I've seen references to the summer of 1969 Ken starting to write the paper filesystem. Warner

Things like this don't really occur in one day [1] "Unix was born in 1969 not 1974" - dmr Is it fair to say 1/1/1970 is the spiritual christening and the day to celebrate?

Here's a quote from an interview that Mike Mahoney did with Ken Thompson: (http://www.tuhs.org/Archive/Documentation/OralHistory/transcripts/thompson.…) MSM: At what point did you feel you had something here? Thompson: Um, well, the first one was not at all multiprogrammed, and was almost like subroutines on the file system. The read call, the system read call, was in fact the call "read" of the file system and it was very synchronous, just subroutine call to the file systems for these applications. And um there was a very quick rewrite that admitted it was an operating system, and it had a kernel user interface that you trapped across. I really can’t remember what the realization was, I mean, the whole time span, from initially starting with...walking downstairs, down there with the idea that we were going to build a file system. MSM: When was this, do you remember the time? Thompson: Yeah, it was the summer of ‘69. MSM: Summer of ‘69 ok Thompson: In fact um my wife went on vacation to my family’s place in California to visit my parents -- we’d just had a new son in August ‘68 -- and uh they hadn’t seen the kid so (unclear) took the kid to visit my family and she was gone a month to California and I allocated a week each to the shell, to the operating system, the shell, the editor, and the assembler, to reproduce itself. During the month she was gone, which was in the summer of ‘69, it was totally rewritten in a form that looked like an operating system, with tools that were sort of known, you know, an assembler, an editor and a shell. If not maintaining itself, right on the verge of maintaining itself, to totally sever the GECOS connection. So, while we don't have an exact date, it's reasonable to assume that, sometime around July 1969, Unix was at a point where it was self-hosting. Ken is a subscriber to this list, so maybe he might be able to help narrow down the date. Cheers all, Warren

The Roman calendar before was counted ab urbe condita (from the foundation of the city, i.e., Rome) in 753 BC, so that year was the start of their Epoch. I think it is fair to say that our calendar started on 1/1/1970, and not because UNIX was born on that day, but because that day was chosen arbitrary by the Fathers of UNIX. We, as UNIX disciples, should start counting our calendar starting with the UNIX Epoch, so we have 48 and not 2018 now... --Andy
