Test flakiness is a common problem across every engineering organization but is often ignored and treated as a simple nuisance. With FlakyCI you can take steps right now to reduce or even eliminate it. It’s a project built with elixir and for elixir.

Last Friday we premiered the first edition of the Subvisual Live Talks, a live stream with a very simple concept: a conversation with interesting guests.

We will stream the second edition on April 23 at 6PM GMT+1 featuring Saša Jurić! Tune in for an hour of fun, Elixir and mostly fun Elixir.

Sometimes you might need to execute code dynamically based - for instance - on the name of a module, akin to code reflection on other languages.

In Elixir one way this can be achieved is by using Erlang’s :code module. As an example, say you want to run a function in a module named MyProject.Foo.

In this guide I present how to quickly make a typical HTML resource come alive using abstraction offered by Phoenix.LiveController. As a bonus I also present how to get Phoenix 1.4 app prepared for Phoenix.LiveView. All wrapped in an approachable step-by-step diff-backed cheatsheet.

This is a first installment in a series about going all-in with Phoenix live views, including as many HTML routes as possible, complete live navigation, integrated authentication solution and perhaps more.

This video series starts from building a basic phoenix app and continues all the way through setting up automated deployment to a Digital Ocean server with GitHub Actions. The videos are in parts:

• Create a Phoenix app with MySQL
• Setup version control with git
• Create and setup a Digital Ocean server
• Install Erlang, Elixir, Node and MySQL
• Install and setup nginx with Let’s Encrypt
• Compile and release the app
• Automate deployment with GitHub Actions

A picture worth a thousand words

I installed Elixir 1.5-rc.0 and gave a new Request Logger a go.

EGO is simple language created for learning purposes. I wrote very basic lexer of Ego in Elixir. All work based on java version of that lexer written by Jarek Pałka and Wiktor Sztajerowski.

One of the great benefits of the way processes work in Elixir is being able to easily opt-in to synchronous or asynchronous behavior. We cover how to do this in a video.

“Design for Scale and Low Maintenance” by Gheorghina at ElixirBerlin’s April remote meetup

Phoenix.LiveController comes in to organize live view code that covers multiple live actions in a fashion similar to how Phoenix controllers organize multiple HTTP actions. It provides a pragmatic convention that still keeps pieces of a stateful picture visible by enforcing clear function annotations.

Learn more about the library & see examples in documentation on HexDocs and get the code from repo on GitHub.

Coming soon: blog post that’ll explain how the library came to life and that’ll guide through converting regular HTTP controllers to live controllers.

Slow recompilation means slow feedback loop and distrupted workflow. Let’s find out how to fix this.

In this episode of ElixirMix, we talk with Alvise Susmel about building Elixir systems that leverage Python image detection on video frames. We cover Ports vs NIFs, using different platforms for their strengths, cool embedded hardware, displaying real time results in Phoenix or Scenic, and much more!
