This week kicks off with some standard dad-cast about kids, eye glasses, and problems with being dizzy. Chris tries to steer the conversation towards the main topic of the week: Umbrella apps. Chris and Amos provide some context for umbrella apps and explain the ways that people tend to use them. Chris talks about his experience building phoenix applications and what he values when designing systems.

Anna joins half-way through and provides an impromptu opinion on umbrella applications. She provides a status update on the goings on of San Francisco and its current weather patterns.

Chris and Amos finish up with a recap of their discussions and some ways that they grow systems over time.

This week the hosts are joined by special guest, friend of the show, and author of Elixir in Action Saša Jurić. The conversation kicks off with a discussion of protein poisoning before quickly turning to Elixir in Action. Saša explains his motivation and process for writing.

After this the conversation moves towards Saša’s custom CI service he’s been building. Saša explains the major benefits of using elixir and erlang for these sorts of tasks. He talks about his dream of being able to utilize erlang with no other dependencies.

This week we dive into Amos’s frustrations with emacs. Chris talks about the nature of optimizers and how addictive micro-optimizing can be. There's a lot of bird trailing before the main topic kicks off around 18:25.

The main topic this week is Private Modules. Chris doesn’t think his opinion matters but Amos wants to talk about it anyway. Amos doesn’t know why we need this so Chris tries to provide some context. This eventually leads to a conversation on warnings and how they get surfaced in Elixir. Chris maintains that he’s ambivalent and Amos wants to think about it more. At the end of the show Chris provides some pretty great tips for getting over stage fright before a talk.

Hey y’all it’s Chris. Just wanted you to know that we had a bunch of technical issues with this call. Both mine and Anna’s recordings were corrupted somehow. We’re still looking into why. Because of this the audio quality changes at around the 20 minute mark. We fell back to using the zoom call audio which we typically only use as a reference for lining up all of the other tracks. I just wanted you to know in case you’re sensitive to that kinda thing.

This week kicks off with a discussion of the holidays, the plight of climate change, and the impending loss of Florida. Amos steers the conversation back towards elixir and his experience building a shell for his current client. Chris describe’s his current experience writing Rust. While he acknowledges that Rust is a good language he doesn’t feel like Rust elevates the paradigm of programming enough. Amos asks the other hosts what they look for in packages or libraries. This leads to a discussion of how to design deeper apis while leveraging stateless operations. Chris explains how they’re using stateless patterns in vapor.

Elixir cards are available by tweeting at @elixiroutlaws and @elixircards on twitter with the hashtag #vapor. You can explain to Chris why he's wrong about rust or whatever.

This week kicks off with a discussion on the merits of being punctual and valuing people’s time. The conversation takes a detour into Chris and Amos’s experiences working at the big blue rectangle known as Walmart.

This leads into the main topic for this week which is unit testing. Amos starts off with some definitions and Chris explains why if you’re gunna write a unit test you should actually be writing property based tests. The hosts wrap up the discussion by weighing the tradeoffs of different styles of testing.
