In episode 109 of Thinking Elixir, we talk about a new library in the Nx ecosystem under active development called NxSignal by Paulo Valente. We talk with Paulo to learn what a DSP (Digital Signal Processor) is, how it works, and touch on the kinds of problems it can solve. We learn about his involvement in Nx, where the library is going, and some unusual ways he’s applied it. He also shares how he’s using Nx Explorer on production to clean up and process financial data returned in a JSON API and much more!

Learn all about functors and their benefits, then create a protocol for functors in Elixir. https://blog.appsignal.com/2022/07/26/how-to-write-a-functor-in-elixir.html

The cost of developer time is expensive, you don’t want to waste it! One of our goals in a day-to-day development is to optimize things, and that’s exactly what we should do to our CI’s to reduce badly spent developer time and engage him in something more productive.

In this talk I’ll guide you through some steps we implemented in CI at Curiosum, as well as propose a local CI setup that can be shared across your team. In short: check as much as possible in automated way, and do not waste a time on things you don’t have to in Code Review and daily development.

Paraxial.io protects your Phoenix application from malicious bots. Similar products are reCaptcha and Cloudflare, neither of which are designed for Elixir. Bots are the cause of security incidents such as credential stuffing, credit card fraud, and email spam, causing major problems for application owners.

Starting today, the Paraxial.io beta is open to new users, no invitation necessary. We have published a detailed guide that walks you through how to protect your Phoenix application with Paraxial, via a simple mix dependency.

This article explains Application start phases in live by creating applications and adding lines of code. At the end of this article you will learn more about the Elixir application and its start phases in depth.

I was setting up a new laptop for Elixir development and I opted for “the clean install” approach. Getting VS Code all setup and configured took a bit of tweaking! I wrote up what I learned and the final needed bits into a recipe. Please feel free to share with people new to Elixir and Phoenix development so they can have a smoother experience.

Part 2 of adding authentication to Phoenix LiveView.

In episode 108 of Thinking Elixir, we were surprised to see how well Elixir and Phoenix performed in the Stack Overflow survey results for 2022! Elixir came in as the #2 most loved language and Phoenix as the #1 most loved framework! And this was their first year appearing as official choices in the survey! We discuss what it means, what we can learn from it, how it compares to other languages and frameworks and what it may indicate for the future. We also discuss ideas to help support and grow the community.

Let’s see how code predictability plays a crucial role in a project’s short and long-term health. We will use Elixir’s built-in features for this, like the pipe operator, tuples, and with blocks.

v0.30.0 of Wallaby has been released. https://github.com/elixir-wallaby/wallaby/releases/tag/v0.30.0

Are you familiar with credential stuffing attacks? Maybe you have heard about the dangers of password reuse, and even implemented defenses in your own Elixir/Phoenix apps. Have you ever tested the defense?

In this post, learn how credential stuffing works by writing your own testing program in Elixir. If your Phoenix application stores sensitive data, this is an excellent project to see if your current controls are working.

In episode 107 of Thinking Elixir, we caught up with Alex Koutmos, a co-host on an Elixir podcast, book author, and OpenSource library creator. We talk about some of his well known libraries like PromEx, but then go into some of his potentially lesser known ones like Doctor, Replug, Unplug, and MJML EEx. I’m happy to learn more about MJML EEx, an email formatting library for improved cross-mail client readers! We talk about the Nerves Weather Station book, and his new book project Elixir Patterns that makes heavy use of Livebook. Come enjoy a deeper visit with an Elixir community contributor!

This blog post summarizes my biggest lesson learned from writing Elixir for 5 years: distinguish expected errors and unexpected errors.

So we can safely ignore the unexpected and let it fail. The only errors our business logic need to handle are the expected errors.

Adding authentication to an app that uses LiveView is a little different than a plain old Phoenix app. In this episode, we’ll look at LiveView auth using the ‘on_mount’ and ‘live_session’ functions.

In episode 106 of Thinking Elixir, we learn how the SonicPi project has been letting people live code musical performances for years. Sam Aaron joins us to talk about the project and how Elixir is playing an increased role. The project uses multiple languages and frameworks, in fact, Joe Armstrong created the Erlang portion for handling the concurrent IO needs. We talk about where the project is, what’s new in the upcoming release, and more about the future of Elixir with the project. LiveView as a UI for jamming with your friends in a distributed musical performance tool? Cool! We also talk about SonicPi being used in the education space and introducing kids to coding and much more!
