We talk with Peter Ullrich about his experience sending SMS messages from a Raspberry Pi Zero using Nerves. We cover what went well, what didn’t and get a glimpse into the current state of Nerves for a newbie when dealing with hardware. Peter also tried Livebook for Nerves and had a great experience with that. We discuss the challenges of hardware systems dealing with the “real world” but see how Elixir makes the process easier to model and think about.

We talk with Chris McCord about his recent announcement that he’s moved to work at Fly.io! We cover what this means for the Phoenix project and ongoing Phoenix development work. He shares why he’s excited about the Fly platform which includes how it replaces his need for a CDN! We also talk about the new Phoenix 1.6 release and all the goodness coming there. This release includes the HEEX engine for validated HTML at compile time, making the auth generators official, a new mailer generator, and the move away from Webpack to esbuild. We go deeper on what the move to esbuild means for existing projects before hearing where Chris wants to put his focus next. We covered a lot, so buckle up!

We talk with Marc-André Lafortune about reducing Elixir project compile times. On larger projects, when a single file like a view template is changed and over 100 files get recompiled, there is something wrong. Marc-André explains how he identified the problems in his project and contributed to Elixir’s mix xref tool making it easier for us to find those problems in our own projects! We cover how these tooling improvements were used to improve the upcoming Phoenix 1.6 and Elixir 1.13! An additional mix xref flag was added to run CI checks on our code to prevent accidentally adding code that slows our compile times.
