I am currently working on a basic course about #Linux for people in my local Makerspace.
Ofcourse, you can't really understand Linux without knowing how the state of Unix where in the 80's and 90's - so ofcourse, I am spending atleast 20 minutes talking about it.

What is an aspect that I should'nt miss?
Ofcourse, I'll bring up #GNU and the role if played for the success of the Free Operating System that most of us refers to "Linux" today.

Anything else?

Huh. I lived some of that history.

* Ken Thompson et al develop Unix at AT&T "without institutional support" (1978)
* The source code escapes.
* BSD is developed from it by hippies in Berkeley
* Stallman invents anarchy license
* Some crazy guy in Finland writes a viable kernel while Stallman's back is turned
* SCO Group tries and fails to gain control of Linux. CEO dies in obscurity
* Ruthless corporate interests continue to attempt control and exploitation with limited success.

That's cool! I was'nt even born...

Your list is basically what I have written so far, with some memes to appeal to a young and bored audience.

Very Kewl! My boss was tryin' to make SCO Unix work on his PC back in the late '80's. It was a long and ultimately futile battle.

I worked on HP-UX and AIX after cutting my teeth on RT-11, RSTS/E, and VMS. Unix was definitely easier and more fun, even with the various misfeatures IBM and Hewlett-Packard put into it. My first actual Linux distro was Slackware in around 1995. I never looked back.
