[emacs-berlin] Literate dev-ops

[Arthur Leonard Andersen]

That's awesome! Thanks for hinting me to this video again. It was in my
"watch later" list, but I just forgot.

I did not know about the tower of babel. This will simplify many of my
org-files!

You tweeted you'd use this to setup your lambdaisland server.
How do you save config files from an org-mode block to the server?
I know for sure I am overlooking something here... but trying to execute
a yaml block just gives me "No org-babel-execute function for yaml".
