    Lorinda Cherry, an ex-member of Bell Labs, passed away. She did well-known tools such as dc, bc or eqn. This post from Doug McIlroy on TUHS is a nice technical biography.

      dc -e "2 3 7 499 1543873789841 2d3 7d181 21617 42743 54909343 503569221839329 34232707540093883 891665010438258643967299***********1-*****P"

        Unfortunately I doubt Lorinda’s dc would work for this. Looking at V7 and V8 source code: https://minnie.tuhs.org/cgi-bin/utree.pl?file=V7/usr/src/cmd/dc/dc.c https://minnie.tuhs.org/cgi-bin/utree.pl?file=V8/usr/src/cmd/dc/dc.c the numbers on the stack are represented by a list of char each less than 100, and P simply print out each char in reverse order.

          Yeah. It works with GNU dc, which is fantastic. It’s great how good code can start simple and humble.

            This works in 9front and plan9port, as the dc(1) there is very similar to V7 and V8.

            dc <<.

        Less technical and detailed (but with some distinct stories and quotations):


        Some other material:

        I’d be curious to see her appearance on the Today Show that McIlroy mentions. She and Nina Macdonald were on in May of 1981 to talk about Writer’s Workbench, but so far I can’t find any video.

          V10 has WWB: https://minnie.tuhs.org/cgi-bin/utree.pl?file=V10/cmd/wwb

          I guess UNIX’s license pretty much doomed its existence? What exactly is its license? Anybody knows?

          1. 4

            Originally, none at all. As I understand it, V9 and V10 never escaped Bell Labs until 2017, so they were private IP..

            Post-2017, there’s a public statement that “Alcatel-Lucent will not assert its copyright rights with respect to any non-commercial use” of Research Unix, which somewhat resembles a license, but in any case wouldn’t allow derivatives to be released under any OSD-compatible license.
