Elixir Outlaws

This week Chris and Anna discuss forever projects, privilege, and preparations for GigCity Elixir.

This week Amos and Chris recap their favorite talks and experiences from ElixirConf 2019.

The hosts talk about preparation for ElixirConf. Chris starts talking about Humidity for far too long before Amos pulls the ripcord. Chris mentions his breakthrough with Norm and Amos wonders if Chris has any thoughts about how to work through mental blocks. Chris talks about running and how useful pi-holing the elixir forum and twitter can be.

This week kicks off with a discussion of database indexes, Datalog, and Datomic. Amos wants to talk about error handling and when to report errors to an external service. He thinks that the goal should be to get the reported errors to zero, and Chris thinks that’s not possible. Chris explains the ways that he reports metrics and errors to collection services. The conversation moves to circuit breakers and common patterns for handling overload in service calls. Chris and Amos wrap up with some tips for debugging production problems with the scientific method.

This week kicks off with a discussion about San Francisco's iconoclastic - but also incorrect - name for a specific coffee drink. Amos is, as they say, coming in hot and launches full bore into a discussion about the elixir forum’s moderation policies. Chris is primarily concerned about the angry letters they’re going to receive. The hosts discuss the benefits of moderating a community. They all agree that moderation is a good thing and helps a community stay healthy, but they also agree that silently editing people's posts is like, kinda creepy. Anna brings up the topic of “forever projects” and how draining they can be. She asks the guys if they have any solutions for scaling projects that don't have a defined "end". The hosts discuss burnout, the pain of invisible work, and how people can help create a more vibrant and rich community.

This week kicks off with an explanation of Chris’s so called grooming habits. Amos explains how to properly cook fried eggs. The guys remember the early days of the show and comment on how their audio quality was somehow even worse back then. Amos is trying to figure out the best way to give back to the community. The discussion moves towards the social contracts of open source which Chris thinks is a thorny topic. Chris encourages people to contribute in whatever way they feel is best even if it means not writing code. Chris rails against the programming communities obsession with hero culture and the toxicity of “rockstar programmers”. The guys discuss ways to try to build successful teams. Spoilers: the first step is not to hire a bunch of people who want to build RPC when all you need is a blog.

The hosts this week are coming in cold. Amos and Chris are drinking Starbucks, although Amos seems much more upset about it than Chris. Anna has finally returned from her vacation in Japan only to find that her microphone stand no longer works correctly. Anna describes her longest Monday ever and Amos explains why he can’t sleep on planes. Chris has been doing nothing exciting besides not sleeping and keeping his children alive. The conversation moves to design by contract and data specification layers. Chris discusses the libraries he’s been working on and also does a pretty great internet voice. Chris and Anna talk about their upcoming elixirconf talks and how they’re happy to see more diversity in the speaker lineup for elixirconf. This leads to a discussion of other conferences and how they pick speakers. Finally the hosts wrap up with a pitch for LazyRiverConf occurring simultaneously with ElixirConf.

This week Elixir has been uninstalled from Amos’s laptop and Chris is reading books and writing C. Chris explains why he still chooses to write C and why most people don’t need to manually manage memory. During the main topic Amos describes a problem he’s having with Tesla and Hackney. This leads to a discussion about how to build systems that can handle failure. Amos brings up Let It Crash and where it applies. Chris provides some insights into building stable systems and how supervisors influence design.

This week Amos is back from his yearly vision quest and Chris faces the problem of being interested in too many things at once. Amos discusses some experiences using Broadway and GenStage which gives Chris an excuse to bring up Little’s Law (as if he needed one). The main topic this week is observability. This topic is motivated by Amos’s latest book: Behind Human Error. Amos provides a brief rundown and Chris talks with authority about things he really doesn't understand. The guys discuss the importance of setting goals for your services and how those goals will inform your metrics gathering and alerting strategies. The show wraps up with some tips on benchmarking and profiling.

4th wall break Hey everyone, we're still wrestling with audio gremlins. This week is based on the raw audio from our call so you'll hear some artifacts in there. I just wanted you to be aware in case you're sensitive to that kind of thing. We've solved this problem so going forward this shouldn't happen again. -Keathley Notes This week starts with some serious discussion about the nature of hammocks, podcasts, and the Coriolis effect. The main topic this week is implicit vs. explicit. Chris argues that an implicit apis tend to be better apis. The hosts discuss where the lines should be drawn between making an operation explicit and hiding the internal complexity of the system. Chris describes how we should think about building a system in layers and how to avoid breaking changes.

This week kicks off with Chris chastising Amos about always being late. The hosts discuss the value of time and recent conference trips. The discussion shifts towards talk preparation techniques, the value of speaking at conferences, and some tips for new speakers. Chris takes control of the show and does a hard pivot towards the main topic this week; the overuse of processes and state management. Chris explains that most people can get by with a lot less OTP then they think. He and Amos discuss ways that they see OTP misused or overused, the nature of scaling systems and the dangers of building stateful services.
