Livebook for Server Admin Tasks

Livebook, initially Elixir's version of Jupyter Notebooks, has evolved into a powerful tool for various uses. One such use is creating runbooks, which are routine procedures and operations carried out by system administrators or operators. By connecting a local running Livebook to a remote live Elixir system on Fly.io, users can perform tasks like finding an account and making it admin, generating revenue reports, and more. The notebooks can be version controlled, kept up-to-date, and shared among the team as they are plain markdown files.
