My ancient history includes …
… old Usenet discussion group
(those that are software related are most likely me.)
In the dark ages I was familiar with
DEC’s VAX/VMS - it
was not called OpenVMS then -
PDP-11 and way, way
I have been a long time Linux user
(my first exposure was to something called Linux
Universe, I still have my first Red
Hat Biltmore disks around here somewhere). Prior to that I knew
Ultrix fairly well.
In this century I have been dabbling with AWS, Debian, and macOS.
