75: RabbitMQ and Commanded at Simplebet with Dave Lucia
We talk with Dave Lucia about Simplebet’s use of RabbitMQ and Commanded for solving unique real-time problems. We learn how Simplebet uses Elixir when creating real-time sports betting markets. We also learn what CQRS systems are, how the Commanded library supports that in Elixir, and how Commanded pairs well with RabbitMQ. Dave talks about moving away from Kafka to RabbitMQ and how that made sense for their use cases. Also valuable, Dave shares where they have found the “dragons” in their design. A helpful discussion that helps identify when CQRS systems might be a tool to use when solving our own problems. Also, Simplebet is betting on SurfaceUI for front-end design in a big and interesting way as well!

74: New to Elixir and Women in Tech with Miki and Kate Rezentes
We talk with mother/daughter team Miki and Kate Rezentes about their experiences learning and working with Elixir and as women in the tech industry. Miki presented “Greasing the Wheel of Adoption” at ElixirConf. Her focus was on the people aspect of adoption and we had a great time going deeper on that topic here. Kate, who is just starting her career as a developer, talks about ways we can share tech with the young people around us. We get their ideas and suggestions for ways to support women in tech, young people learning tech, and more!

72: TypeCheck with Wiebe-Marten Wijnja
We talk with Wiebe-Marten Wijnja about his project TypeCheck that provides a new kind of runtime type checking for Elixir applications. The syntax builds on your existing spec types so it still works for dialyzer but adds additional compile time created checks. It also works for generating property based test data. This feature comes out in a new ability called "spectest". Like doctests, you can have automated checks that verify the function adheres to the spec! We also cover how TypeCheck allows writing type declarations for other libraries like Ecto and Plug. There are some interesting ways for people to contribute! A very interesting library!

71: LiveView and the 7-GUI Tasks with German Velasco
We catch up with German Velasco then talk about how he learned of the 7-GUI Tasks online challenge and how he wanted to see how LiveView could approach it. We talk about his ElixirConf presentation and how the idea of modeling state impacted his solutions to these problems. We go over what these common UI patterns are and how LiveView is able to approach them differently. We talk about Chris McCord’s idea of “Live Apps” and how LiveView really is different from what other languages and communities can do. We discuss using LiveView to implement UI patterns that it wasn’t designed for and how that process has gotten better over time and much more!

70: PardallMarkdown with Alfred Reinold Baudisch
After a big news section, we talk with Alfred Reinold Baudisch about his project PardallMarkdown. It's a reactive Elixir server that reads markdown files, compiles them to HTML, stores them in an ETS table, and serves them up. It's a different take on serving markdown files for a blog. It can also be used as a wiki and supports deeply nested hierarchies. An interesting feature is it can be used as a library inside your own Phoenix application to provide blog posts or other "static" content.
