Elixir, The story

Start your week right with some Elixir inspo. Have you seen Elixir: The Documentary yet? A couple of years ago, Honeypot produced the Elixir origin story, which explores how it came about and how it has grown since its creation (spoiler: it’s thanks to you, Elixir dev). Definitely worth a rewatch if you’ve seen it already ;)

The BEAM marches forward

The BEAM is the virtual machine that Erlang and Elixir runs on. It is widely cited as a battle-tested piece of software though I don’t know in which wars it has seen action. It has definitely paid its dues in the telecom space as well as globally scaled projects such as Whatsapp and Discord.
