How to Sell Elixir AGAIN (2023)

Presented by Evadne Wu at Code BEAM Lite in Stockholm, Sweden on 12 May 2023

Synopsis

We have celebrated 10 years of Elixir and also nearly 25 years of Erlang since the open source release in December 1998.

Most of the libraries that were needed to make the ecosystem viable have been built, talks given, books written, conferences held and training sessions provided. A new generation of companies have been built on top of the Elixir / Erlang ecosystem. In all measures, we have achieved further reach and maturity than 5 years ago.

# Toggle all currently 'Active' network servcies (e.g., Wi-Fi, Ethernet
# connections, etc...) to "restart" them. We'll ignore any already 'Disabled'
# services, and toggle all of the others to 'Disabled' and then back to
# 'Enabled'. This has been found helpful when your VPN won't re-connect after
# undocking and re-docking your MacBook, for example.

The 5-minute backpack demo

Here's what I carry in a Tom Bihn Synapse 19 bag when I travel for 1-to-n days. In general, I optimize for low-weight items, with a secondary focus on reducing maintenance. You can peruse a gallery of pictures, too.
