Monitoring the Erlang VM With AppSignal's Magic Dashboard

Today, we will dive into one of the hard parts of using any monitoring - making sense out of all the data that is emitted. We think this is one of the hard parts. And being developers building for developers, we think a lot like you do – we think. Pun intended. Nowadays, we monitor AppSignal with AppSignal (on a separate setup), so we are still dogfooding all the time. We still run into challenges as you do, often before you.


How to Get Your Elixir Application Ready for CI/CD

In today’s post, we’ll go over what continuous integration and continuous delivery are, the benefits that come along with employing CI/CD, and some best practices that you should follow. We’ll also explore a wide array of Elixir ecosystem tools that can help you create top-notch CI pipelines. In order to experiment with a handful of the tools that we will be discussing, we’ll use a Git hooks Elixir library to execute our CI/CD validation steps, but on our local machine.


How to Use Broadway in Your Elixir Application

In today’s post, we will be covering the Elixir library named Broadway. This library is maintained by the kind folks at Plataformatec and allows us to create highly concurrent data processing pipelines with relative ease. After an overview of how Broadway works and when to use it, we’ll dive into a sample project where we’ll leverage Broadway to fetch temperature data from https://openweathermap.org/ in order to find the coldest city on earth.


Typespecs and Behaviours in Elixir

Today, we will dive into Typespecs and Behaviours. These are two Elixir features that we are ecstatic (pun intended) about. They are great examples of built-in features in Elixir that help get some of the advantages of statically typed code. Alright, let’s set the scene. Elixir is a dynamically typed language. This means that the type of each variable is not checked at compile-time, but rather at run-time. Like most things, this comes with advantages and disadvantages.


How to use Mint, an awesome HTTP library for Elixir - Part 01

Mint is a shiny new Elixir package which allows you to make HTTP requests using the HTTP 1 and HTTP 2 protocols. It can transparently handle ALPN (Application Layer Protocol Negotiation), which essentially means that it can figure out if a server uses HTTP2 or HTTP1 on its own. It also comes with an optional dependency on a castore package which verifies the SSL certificates of the servers (that you connect to).


Elixir Overview and Tutorial (as told in a Wizard fable)

Interested in Learning the Elixir language? Join us in this entertaining Elixir tutorial and overview. This post will spin a yarn about an ambitious wizard, Alatar, and his quest to revamp a magic web storefront using Elxir. We will observe Alatar decide on Elixir as his development platform, and follow him on the journey of learning and implementation. Along the way, he will utilize several frameworks written for Elixir (including Phoenix, Ecto, and Poison).


Wrapping Up ElixirConf 2018

I'm on the 6:10pm Amtrak Cascades out of Seattle, scheduled to arrive in Portland at 10:00pm. After two intense days in Bellevue, I'm exhausted, but wired. A group of young guys two rows up are loudly discussing their favorite AWS services; I wonder if they're also returning from ElixirConf, but then I remember that this is Seattle—half the city works in tech.
