In this post, you’ll learn how to use ETS as a caching mechanism in your Elixir applications, get familiar with different available options, and be made aware of some things to keep in mind.

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.

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).

Last week was amazing. It was our first ever Honeybadger Hack Week. We got to take a momentary break from thinking about exceptions and uptime to focus all our energies on something completely new. We decided as a team to build a small app in Elixir and Phoenix.

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).

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.

Browser development tools - like Chrome Dev Tools - are vital for debugging client-side performance issues. However, server-side performance metrics have been outside the browser's reach. That changes with the Server Timing API. Supported by Chrome 65+, Firefox 59+, and more browsers, the Server Timing API defines a spec that enables a server to communicate performance metrics about the request-response cycle to the user agent.

This month we released a new version of our hex package, which includes a major refactor of the internal client logic as well as some new features, improvements, and bug fixes. We're super excited to share the release of honeybadger v0.7 with you! Here are the highlights.
