Thinking Elixir Podcast

After covering the news, we share a live recording of the show from the Lambda Days conference. It was a lot of fun! We covered topics like learning and teaching Elixir, functional programming, strengths of Elixir over Erlang, the developer tooling, why Elixir is awesome even when not building distributed systems, and much more!

Alexandre Minette shares his adventures with LiveView as he builds a personal finance tracking application. We cover his use of hooks to integrate Javascript libraries that give him the UX he wants. He shares some tips and resources for finding Javascript libraries that work well with LiveView. Alex pushes browser locale data up to the server to customize rendering dates and times for a fun and different approach. We also get his perspective on using Flutter for Mobile development and where he thinks it fits with web technologies like LiveView.

Tyler Young from X-Plane talks with us about how he added a new MMO feature to the popular flight simulator using Elixir. He shares some behind the scenes information on how it was created and how it’s been working in production. We learn about the single modest server that supports all the mobile users right now. I loved hearing how Tyler found working with Elixir to be super productive. He took on a major new feature that he expected to take over a year but was able to deliver it in less than half the time. He did all the Elixir work himself and was new to it!

José Valim visits and finally publicly reveals what Project Nx is! He and others have been working on it for 3 months and he's finally ready to unveil it. José will speak more about it at the LambdaDays conference, demonstrating it with code and announcing the release and availability of the OpenSource code. Nx stands for "Numerical Elixir". The Nx project brings a unique numerical mode to Elixir along with GPU support. This important work lays the foundation for a powerful new era with data science in Elixir! Listen in as Jose discusses the details of how this works, how it came about, the goals of the project, what this means for the community, and what comes next.

We talk with Allen Wyma about a Postgres PubSub feature and how it plays nice with Elixir. We dispel the idea that you should always use Phoenix PubSub just because it's there and we cover the value of learning what's built-in to tools like the postgrex library. Allen shares how Postgres PubSub elegantly solved a problem for him and he gives tips for using it. We also talk about teaching Elixir through Allen's YouTube videos and teaching in person with his Teach Me Code efforts.
