In this GitHub repo I’m sharing an example of using Code.eval_file, GenServer and PortMidi to create some sort of music live-coding environment (as featured in an ElixirConfEU lightning talk), where the current “music position” is remembered across reloads.

Make sure to check out the Youtube video I posted to see a demo!

If you ever wanted to take a Raspberry Pi (or any linux-based platform exposing an i2c driver), a connected sensor, and wrap them both into an Elixir program but thought it might be too daunting of a task, this article is for you! In this article, we are going to focus on a simple i2c device that senses temperature and humidity and demonstrate how to write an application that will run as a GenServer. You can use this application (available as a hex archive) to request a measurement in your application by including it as a dependency.

We’ve released a BETA version of our Elixir app monitoring library, scout_apm. Scout instruments Phoenix (controllers, views, and templates) + Ecto, and has support for custom instrumentation.

Detailed transaction traces are collected as well.

We offer generous (I think) free plan. Get started.

We’d love your feedback: lots more is planned.
