Hey everybody and welcome back to Season 2 of the podcast! This season we will be talking about Elixir internals, libraries and the inner workings of the language. In our first episode we are very happy to be joined by Brooklyn Zelenka to start off our journey on the subject with an exploration of her very own Witchcraft.

In this episode we talk to Brooklyn about her history with Elixir, how she got started and what attracts her to it. Brooklyn explains the influence that open source philosophy has had on her career in developing and from there she gives a pretty comprehensive introduction to what Witchcraft is, expanding its key concepts. Although this is quite a high level discussion about Elixir and Witchcraft, we are confident that with Brooklyn's expert help even our most uninitiated listener can get some benefit from our conversation. We also talk about type systems, property-based checking and Dialyzer, so for all of this and more make sure to join us as we kick things off for Season 2!
