This week starts with Amos describing the new features elixir 1.7 and Chris explaining some queueing theory. Afterwards Anna describes her experience solving a bug in her crypto-currency exchange. This leads to a discussion on how to find bugs in distributed systems, the dangers of generating data based on types and how to guide generators so they find more bugs.

Anna, Amos, and Chris start this week by discussing the recently released elixir documentary. Amos brings up the virus that was discovered in eslint-scope which detours into a conversation about reading through library dependencies. The hosts eventually make their way to the main topic for this week: How to find the correct restart intensity for your supervisors.

This week Amos kicks off the show by talking about his memory issues and Anna discusses her work on building a crypto currency exchange. The hosts then dive in to the main topic of this week: is Erlang "the most object oriented language" and if so is that a good thing.

Amos kicks off the show by lamenting how old he is. Afterwards Anna, Amos, and Chris discuss the new features coming to erlang/OTP 21. Chris proceeds to bum everyone out by talking about how burnt out and unethusiastic he is about his open source projects. Anna and Amos help to provide perspective and encouragement.

This week the outlaws are joined by Jose Valim and Chris McCord. After working out the confusion of having two Chris's and giving Keathley a timebox for controversial topics Jose and Chris provide some insight into the projects that they're currently pursuing. Afterwards they discuss ways that the elixir community can continue to grow, things that the community is doing well, and areas where we can improve.

Special Guests: Chris McCord and Jose Valim.

This week Anna, Amos, and Chris are joined by special guest and newly appointed Friend of the Show: Michal Muskala. After Michal teaches everyone how to correctly say his name they discuss the recent CodeBEAMSTO and optimizing elixir code for the BEAM. Chris attempts to avoid talking about config but the other hosts are wise to his schemes. Michal offers his opinions and insight into the issues with configuration, releases, and hot upgrades.

Anna, Amos, and Chris discuss the current state of configuration and the new proposals for making configuration behave in less surprising ways. Chris lays out the context and then claims he's going to stop talking. His silence lasts just long enough for Anna and Amos to provide their own opinions on the situation. Chris jumps back in and provides an alternative solution to the configuration problem and explains why it will never be adopted. As the show closes, Chris continues to talk to much while Anna and Amos provide thoughts on how to help educate and grow the elixir community.

• Proposal: moving towards discoverable config files - Elixir News - Elixir Forum — One of the major differences between running your application as a release and as a Mix project is the differences in configuration. Mix evaluates the configuration right before the application starts, releases evaluates the configuration when your application is compiled.
• The Erlangelist - Rethinking app env — What is app env, and what should we use it for?
• Rethinking app env - Discussions - Elixir Forum — This is a spin-off from the discussion about the new config proposal. I’m replying to this post 8 by @michalmuskala separately, to avoid noise in that thread.

This week the outlaws are joined by Friend of The Show, Ben Marx. In between name dropping and sports idioms they discuss OpenTracing, OpenCensus, purely functional data structures, distributed systems, and Amos's experiences with living in the desert.
