Personal notes from Lonestar Elixir Conf 2019

I just came back from Lonestar Elixir Conf 2019 in Austin, Texas. The conference was a single track, 2 days, with an extra day for an optional training (that I didn’t attend this time). Even not been considered the most important conference in the Elixir ecosystem in the US, the lineup was really great, with 4 keynotes including José Valim (Elixir creator), Chris McCord (Phoenix creator) and Justin Schneck (Nerves co-creator) and great talks.

Getting started with Scenic in Elixir — Crafting a simple snake game

Cool CLIs in Elixir (Part 2) with IO.ANSI

IO.write/2is a cool function, but the real work there is done by the carriage return (\r). Carriage returns are a control character that let you reset the cursor to the beginning of the current line of text, similar to how an old-fashioned typewriter works. There are many other control characters that do a similar job. If you want to learn more about the history of how terminals and command line interfaces came about, I highly recommend this Crash Course on Keyboards & Commend Line Interfaces.

Hey Process, there is a Message for you!

Messages are a fundamental part of concurrency in Erlang and Elixir. In this article I introduce how messaging between processes works. We play with simple examples to see how a process sends and receives messages.

The Versatility of Function Declarations in Elixir

Over the past few months I’ve been lucky enough to use Elixir at work. I wrote some hobby projects in Ruby in the past, so my first surprise was in finding out how differently Elixir behaves despite the syntactic similarities between the two.
