Thinking Elixir Podcast

Michael Davis explains Slipstream, a Phoenix channels websocket client library that enables Elixir applications to become a client of a Phoenix channel on another server. Out of this work, an underlying websocket library was created built on mint, which has now officially become part of the mint project. We talk about other libraries in the same space and why Slipstream was created. Michael was also involved in the recent Tree-Sitter Elixir work that Github celebrated and he shares some insight into that work as well!

Dominic Letz did something I thought was impossible. He got an Elixir application packaged up, approved, and available through the Apple App Store on iOS devices. The application runs Elixir on the device, creates a web view, and hosts Phoenix LiveView pages. They went further and created a bridge to integrate with more of the platform specific features of the device. Is Android your preferred platform? They have it running there as well and in the Google Play Store. We talk about how it works, challenges overcome, and where it is now. They also created several Github projects that show how to do this yourself to create a cross-platform desktop application and apps for Apple and Android mobile devices. Very cool! They want your help to make it even better.

Dave Lucia released version 2.0 of AvroEx, an Elixir library for working with Avro protocols and schemas. To understand Avro, we need an overview of the whole Kafka-centric flow! He gives us a taste of the Enterprise soup of JVM tools used for populating data lakes, all for the business benefit of data analysis and machine learning. We may work on Elixir systems that are tasked with hooking into this other Enterprise-y world and getting an overview of the pieces and awareness of the tools available can really help out! Dave also shares his goal of creating a new Markdown parser for Elixir and updates us on the next chapter of his professional journey.

José Valim returns for part 4 in our 5 part series as we count down to the 10 year anniversary of the Elixir project we know and love! In Part 4, we talk through the Elixir releases of 1.10, 1.11, and 1.12. We go deeper on the philosophy of “explicit vs implicit” and how that informs many design decisions about the language. We learn about how Elixir and Erlang loggers were unified, how matching on map keys in guards enabled receives block enhancements, how common date sorting bugs were solved with Enum.sort improvements (that you should really listen to), the improvements to application config, how exceptions work in Erlang and Elixir and much more! A packed episode!

The recent announcement of Rustler Precompiled prompted a lot of interest and questions. We talk with Philip Sampaio to understand what he created and what problem it helps solve. The project helps lower the bar for using Rust libraries for NIFs in Elixir making it possible to see more libraries using Rustler in the future. He explains what prompted the work initially and how projects can benefit from it. We discuss what it means for internal company projects and especially for libraries. He explains how the project addresses the many architecture and platform combinations too. We end with learning about his sample CI project that shows us how to set up our own CI systems to use it.

We talk with Tobias Pfeiffer about his popular performance benchmarking tool Benchee. We learn about why he created it, what's special about it, and the big features in the latest release. It was 2 years between this release and the previous one. Tobi talks openly about the technical challenges that compounded with personal challenges, feelings of obligation, anxiety, and the drive for perfection. As developers, many of us struggle with these same issues and it helps just hearing that we're not alone.

We talk with Mitchell Hanberg and learn about why he created the alternate Phoenix templating language called “Temple”. He explains how Temple works, some of its unique benefits and where he's going with it in the future. Mitchell also took over maintenance of the testing project Wallaby from Chris Keathley.

José Valim returns to continue with part 3 of our 5 part series as we count down to the 10 year anniversary of the Elixir project we know and love. In Part 3, we talk through the Elixir releases of 1.7, 1.8, and 1.9. We talk about the unification efforts between Elixir and Erlang. These came through changes to error stacktraces, how documentation is stored, a unified logger, and more. We learn how features like Mix.target made a big difference for the Nerves project. We also hear the call for contributors to help bring a few remaining date/time features to Elixir. The big feature in Elixir 1.9 was the addition of deployment releases and the early efforts at managing config for releases. We thought this would be a short episode but found there was a lot to talk about and learn!

We talk with Tetiana Dushenkivska, the creator of Elixir Cards, a series of Elixir flashcards with multiple ways to use them. We talk about why she created the cards, how they helped her, and how others have used them. We talk about learning models and the importance of repetition for memorizing things. Tetiana shares how LiveView is used in the creation of the cards and more! David shares how he used the cards for fun drills at meetups and Tetiana fondly recalls a tournament held at a previous Elixir conf. She also shares what she's working on now for a future online learning system.
