What makes Plan9 different: https://posixcafe.org/blogs/2024/07/27/0/ Why Plan 9 by Russ Cox https://pdos.csail.mit.edu/~rsc/plan9.html History and Motivation http://pub.gajendra.net/2016/05/plan9part1 Plan 9 from Bell Labs http://9p.io/sources/plan9/sys/src/ GitHub https://github.com/0intro/plan9

Source code for the curious: https://github.com/0intro/plan9/tree/main/sys/src/cmd/mk

Source for the mentioned script: https://github.com/0intro/plan9/blob/master/rc/bin/who. Also, other utilities implemented as scripts are fshalt (P9's shutdown), kill, lookman (P9's apropos), uptime and whois.

The program is still in Plan9. http://9p.io/magic/man2html/1/p https://github.com/0intro/plan9/blob/master/sys/src/cmd/p.c

No, it wasn't. Pcc is just kencc ran through a special mode and with special APE libraries. It has nothing to do with S. C. Johnson's pcc. > The pcc command acts as a front end to the Plan 9 C compilers and loaders. http://man.cat-v.org/plan_9/1/pcc http://doc.cat-v.org/plan_9/4th_edition/papers/ape https://github.com/0intro/plan9/blob/master/sys/src/cmd/pcc....

Dennis Ritchie explained that it is Plan 9 CPU server in drawterm. You can find a list of dictionaries available on Plan 9 inside Bell Lab at https://github.com/0intro/plan9/blob/7524062cfa4689019a4ed6f... Unfortunately only "pgw" and "roget" are publicly available. The rest are likely died under the onslaught of copyright.

The Plan9 Source code https://github.com/0intro/plan9 > A Professor of Computer Science gave a paper on how he uses Linux to teach his undergraduates about operating systems. Someone in the audience asked 'why use Linux rather than Plan 9?' and the professor answered: Plan 9 looks like it was written by experts; Linux looks like something my students could aspire to write. But see also the HN thread : Code which every programmer must read before dying https://news.ycombinator.com/item?id=2466129

Lisp and ML represent quite different models of computation. For a register machine, C can be pretty beautiful. It's funny you talk about parsing command line options. Plan 9 solved that problem well with the arg(2) macros. [1] In fact, Plan 9 in general is a premier example of really clean and elegant ANSI C-compatible code.

I've been reading about Plan 9 lately but I am still missing why exactly (or more-or-less) Plan 9 (and Research Unix, similarly) fell out? From what I've read it seems like the lack of ubiquity forced the Plan 9 guys out of Plan 9 and back into Ubuntu or OpenBSD. From their discussions of rc, etc it seemed like the lack of users caused them to move away from it until it just completely fell apart... But I'm not sure? And where is Plan 9 now? If I want to get involved should I look into 9front? Inferno? Or this guys github mirror [0] because the Plan 9 website is down? I understand these are some smart guys, but the cat-v website makes a ton of divisive statements and "leaves it as an exercise to the reader" to figure out why they hold these views. The trolling isn't awful, but in general, I'm having a really tough time fighting my way int
