I made my first IoT Example using a RaspberryPi and Arduino, connected with Elixir using UART Nerves project and Phoenix Framework. Complete post here: http://carlogilmar.me/post/learning-iot/

Extension to Embedded Elixir (EEx), that allows content to be safely embedded into HTML. Handles auto-escaping and safely injecting JavaScript variables.

Last week at ElixirConf, Chris McCord announced a new project called Phoenix.LiveView. I believe this library has the potential to reshape the way many developers build reactive user interfaces on the web. Here’s why.

How to create pipeline modules where you could read them like a poem and know, without going deep in the implementation, how the working flow works.

Supports HTTP/1 and HTTP/2 and isolated configurable connection pools. Heavily used in production for 6 month now!

As part of my ElixirConf talk, I showed off Squabble my new Elixir package for selecting a leader in your cluster. Squabble uses the leadership election part of the Raft Protocol. This was pulled out of ExVenture, my clustering text based multi-player game server.

There is far and way a single type of assertion I’ve see that is responsible for more test flakiness than any other. It’s probably the culprit for more than half of all test failures that shouldn’t fail. But there’s an easy way to make your tests less flaky!

Let’s dive into how I’ve been using the “facade” pattern to simplify and shorten my Elixir modules.

Ecto.Multi, a data structure added in Ecto 2.0, is an extremely useful tool for creating and executing complex, atomic transactions. This very brief guide will cover a few of the most useful methods associated with Ecto.Multi and when to use them.

In this episode of Elixir Mix, the panel talks to Daniel Spofford who is a Senior Software Engineer through Very where he uses Elixir constantly. Check out the episode to get more information about Elixir, Phoenix, Logging, and things to consider when deploying and supporting Elixir applications.

In the week or two leading up to ElixirConf I started trying to see how far I could push ExVenture with concurrent players.

I was able to do three simple changes to go from maxing out at 230 concurrent players to maxing out at 3500 concurrent players on the same machine, 15x more players.

Lots of news for users of the Spandex library for tracing their Elixir applications with OpenTracing and DataDog!

• Spandex 2.2.0 has been released at its new home in the spandex-project organization on GitHub: https://github.com/spandex-project
• The former spandex library has been split into a core library and several optional dependencies to allow you to choose the frameworks you want to trace and the back-ends you want to send the spans to.
• In the future, we envision having support for more OpenTracing-compatible back-ends like Zipkin and Jaeger (contributions welcome!)
• spandex_datadog now supports distributed tracing across services, including priority sampling to ensure your traces are always complete.

Check out the READMEs in the project repos and join us in the brand-new #spandex channel on the Elixir-lang Slack if you have any questions!
