How to add an image to a gist

1. Create or find a gist that you own.
2. Clone your gist (replace <hash> with your gist's hash):

   # with ssh
   git clone git@gist.github.com:<hash>.git mygist
   
   # with https

git clone https://gist.github.com/.git mygist

IMPORTANT: Ignore the out-of-date steps below for getting Chromium keys.

Instead, read this up-to-date guide (Jan 2023) written by @LearningToPi.

P.S. Thank you to every contributor below who provided tips over the years on what should be a straightforward process: setting up Chromium for local development.

Long live the web!

Elixir installation guide

Version numbers should be the ones you want. Here I do it with the last ones available at the moment of writing.

The simplest way to install elixir is using your package manager. Sadly, at the time of writing only Fedora shows the intention to keep its packages up to date. There you can simply sudo dnf install erlang elixir and you are good to go.

Anyway, if you intend to work with several versions of erlang or elixir at the same time, or you are tied to a specific version, you will need to compile it yourself. Then asdf is your best friend.

Ruby Metaprogramming Guide

Note: This guide works with Ruby 2.6+ through Ruby 3.x, with modern Ruby 3.x features highlighted where applicable. Core metaprogramming concepts remain consistent across Ruby versions.

This document has been collaboratively updated and modernized through an interactive process with Claude Code, revised with examples, visual diagrams, and Ruby 3.x compatibility.
