This was discussed 3 months ago:

It's a different url though.

In a typical "early internet" straightforward way, you can just leave out the "dmr" from the URL and get a listing of some other ex-Bell Labs employees. Although at least two other ones I know about (Ken Thompson and Rob Pike) are missing. Some who you might know that are there include Brian Kernighan (the "K" in "K&R C", co-author of "The C Programming Language" and later "The Go Programming Language") and Russ Cox (I think he's the only ex-Bell Labs person left working on Go at Google after Thompson and Pike retired?).

Hmm; they are missing from the index page, but they do exist: http://cm.bell-labs.co/who/ken/ and http://cm.bell-labs.co/who/rob/

I was wondering who was keeping this site/domain up because I thought Bell Labs no longer existed. Only now discovered it’s owned by Nokia (although at a different domain: bell-labs.com)

The history of the Unix pipe operator linked from this page was interesting: http://cm.bell-labs.co/who/dmr/hist.html#pipes

If that tickles your interest you might enjoy some of Doug' other works

https://www.cs.dartmouth.edu/~doug/

particulary the actively adversial anti-quicksort

https://www.cs.dartmouth.edu/~doug/source.html

I strongly advise the history of C, where he acknowledges some of its gotchas, and why lint was created to help catching them.

Many keep thinking they know better than C's authors.

I can't find this book. Can you link me to it?

Not OP but I think this may be it

https://dl.acm.org/doi/pdf/10.1145/234286.1057834

Found via searching for quoted text in http://csapp.cs.cmu.edu/3e/docs/chistory.html

It is linked from the page, and isn't a book.

Thanks!
