Welcome back to the SmartLogic Podcast where we talk about the latest developments and best practices in the web and mobile software industry. In continuing with our theme of Elixir Internals, we’re having a conversation about the inner workings of one of the most popular Elixir libraries, Credo, and we are joined by the author René Föhring.

René shares the story of how he was introduced to Elixir while doing his PhD and looking for a new programming language and then shares the philosophy and inspiration Credo was developed on. Wanting Credo to be a less rule-based, authoritative code analysis tool and more user friendly, René focused on creating it to act as a type of digital mentor to the many developers out there who do not have a human mentor. He also shares about some of the launching hiccups, what he would have done differently had he been given another opportunity and some of the most important lessons that he has learned working in the open source community. Be sure to join us for all the inside info!
