Collected advice on Unix CLI Design & Implementation (Alan Coopersmith's Weblog)

A Solaris-specific view on Unix tool design. (Not always followed in the past -- I have not-very-fond memories of a Sun disk array where the admin command was "rm6".)

Tilde.Club: I had a couple drinks and woke up with 1,000 nerds — The Message — Medium

"This computer ran a Unix-based operating system. It was located somewhere in Virginia. I went to bed. When I woke up 100 people were asking for accounts." An author discovers the social aspects of Unix systems; there are actually lots of shared machines like this around, quietly keeping groups of people happy. (bookmarks.offog.org is running on one...)

Mark Williams Company sources

Coherent is now free software. The source tree is a bit of a mess -- but it has version control information back to 1990 for much of the code, so it'd be eminently suitable for a reconstruction project at some point. (However, I don't think there'd be much point in trying to resurrect the utilities for modern use; they're full of arbitrary limits...)

The EdgeBSD Project: About EdgeBSD

Another NetBSD branch, using Git as the VCS. (It's not clear to me what the "desktop based on DeforaOS" thing is about...)

LSX Unix Restoration page

FreeMiNT - SpareMiNT Wiki

"FreeMiNT is a free, open-source operating system for 16/32bit Atari computers and clones, based on the original MiNT by Eric Smith and officially adopted by Atari Corp. It is compatible with TOS, but adds a lot of new functionality not available in any other TOS-compatible operating system."

dspinellis/unix-history-repo

A merged Git repo containing the source history of Unix from the earliest C versions up to present-day BSD. Very neat!

EtchedPixels/FUZIX

Alan Cox's extended version of UZI, a SysV-ish Unix for 8-bit microprocessors. (I'm trying to persuade myself that it doesn't need a BBC Micro port...)
