@hoernchen72 #coff ? Habe ich seit Jahrzehnten nicht mehr in freier Wildbahn gesehen. Hm, auf #Ultrix/#MIPS muss das damals gewesen sein. Auch #Parix für #Transputer hat es benutzt.

Often forgotten by people is the period in between. The people who cloned Linux and the (GNU) "shell" around it often worked from samizdat doco about 1970s Unix.

In the 1980s and early 1990s, there were a whole bunch of commercial #Unix flavours: #Xenix, HP/UX, #AIX, #SunOS, #Ultrix, OSF/1, AT&T System 3, AT&T System 5, ...

#Illumos, which came from #Solaris, which came from SunOS, is actually still around.

"What is a delay slot? Well, back in the day it was considered cool to expose your CPU's pipeline to the world. Just kidding, it was just a way to save some more transistors."

"The CPU has a register called, literally RANDOM which is supposed to be constantly incrementing, every cycle."

#introduction

#hello people. Ståle from Norway. I've been doing tactical and strategic #infosec and #irt in #HigherED for the last seven years. It all started with a bunch of diskettes and c.o.l.a. in 1993, and since then I've worked as a sysadmin. Mostly unix-es, but also Windows. This includes project management, #monitoring, #architecture, designing an #operations center and touching a bunch of technologies over the years. I still code a little #shell and #python. Been using #cfengine and #tivoli with a smile.

A memorable moment still is opening 7 xterms and compiling X11R6 for #sunos #solaris #hp-ux #ultrix #irix #linux #digitalunix and managing the configuration and security of tons of servers and clients centrally. This must have been 2000 or so.

These days I tend to like logging and #siem frameworks like #elk, teaching users and management how to make smart choices, general config management and hardening, IAM-stuff and the essential symbiosis between #sysadmin stuff and infosec stuff. #isms. #policies. #architecture.

I also like #photography #lego #rpg #larp #cooking #politics #society #emacs #languages #puns. A lot nicer than the picture. He/Him.
