This week Jose Valim joins the outlaws to answer questions from the community.

The conversation starts with a discussion about the current state of dialyzer and future plans to add a type system to elixir. Jose laments some of the decisions to include dialyzer types directly into Elixir. This leads to a discussion of new tools being built for deployment and for metrics gathering. Chris asks about efforts to make it easier to use elixir libraries in erlang and ways that we might be able to share more libraries across ecosystems. Jose discusses plans for extending the functionality of GenStage and Flow in order to help people build more robust data pipelines.

Finally, Jose describes his recent adventures into livestreaming and tries to convince the hosts to livestream the podcast.

Special Guest: Jose Valim.

This week Anna and Chris decompress from GigCity Elixir. They discuss several of the talks including a talk by Stu Halloway about what open source maintainers owe to communities. This leads to a discussion on how to have productive conversations about open source projects. Chris laments some of the ways that he's interacted with the community and Anna pushes for ways to facilitate constructive communication.

This leads to a discussion about good ways to build modules and libraries that can be easily taught to newcomers.

After introducing themselves for the first time in the shows history, James presents several questions for the guests. This leads into a discussion about dependencies, when we should rely on them, and how we should evaluate them. James turns the conversation to a discussion about Anna and Chris's talks at GigCityElixir.

This week starts off with a discussion about Amos and Chris’s recent trip to Strangeloop and the great talks they saw there. There’s a brief interlude into airports and the World Famous sponge display in the Chattanooga airport.

The main topic this week: How do we handle complexity when designing software. Chris, excited after reading Philosophy of Software Design, gets exceptionally fired up about software design and the tradeoffs that programmers make. The hosts discuss the nature of software developers and the ways that programmer culture influences those decisions.

The hosts turn to discussing the recent changes in Ecto which is mostly Chris ranting for 15 minutes because he doesn’t get it (those who dislike rants will want to turn off their podcast players).

• Understanding Formal Specifications through Good Examples — Formal specifications of software applications are hard to understand, even for domain experts. Because a formal spec- ification is abstract, reading it does not immediately convey the expected behaviour of the software.

This week Amos and Chris discuss a fun absinthe bug and try to determine how to pronounce "leex". Chris describes his frustrations with REST and why building clients for REST apis is probably the worst thing ever.

In the main topic this week, Amos expresses his frustration with Purely Functional Data Structures and understanding amortized time analysis. Chris attempts to provide some clarity by describing the physicists method.
