I found that there are some people on GitHub that collect source codes from early UNIX ages, like first compilers, first shells, or PDP7-UNIX. Just to made them available in one place (slightly decentralize access to them) – I decided to create gitlab.com account `UNIX-history` for them.

You can find there source codes from 1970, nicely commented and manually formatted, before this all happened.

Sudo has an easter-egg that’s disabled by default. It can insult you each time you provide incorrect password. Just like that:

[sudo] password for agilob: 
You can't come in. Our tiger has got flu

[sudo] password for agilob: 
You do that again and see what happens...

[sudo] password for agilob: 
You can't get the wood, you know.

[sudo] password for agilob: 
Speak English you fool --- there are no subtitles in this scene.

[sudo] password for agilob: 
I think ... err ... I think ... I think I'll go home

[sudo] password for agilob: 
Where did you learn to type?

[sudo] password for agilob: 
stty: unknown mode: doofus

[sudo] password for agilob: 
Listen, burrito brains, I don't have time to listen to this trash.

[sudo] password for agilob: 
sudo: 3 incorrect password attempts
