    On today’s show, we welcome Justin Schneck and Frank Hunleth, luminaries from the Nerves team! We take a dive into the world of Nerves with them, covering themes of performance, problem-solving, transitioning to hardware, and breakthroughs in the field. We begin with a conversation on how Elixir handles performance issues on the range of devices they support and Frank gets into how the team solved an early boot time discrepancy between a PC and a Raspberry Pi board. Other big themes for today are ironing out the kinks in the system registry model and merging Erlang and into hard real-time. After squeezing some information out of the guys about their use of ugly code hacks we get into some visionary decisions as well as things the team wished they could have done differently at Elixir (see the release of the new networking stack). Finally, we end off with what Frank and Justin are excited about as far as developments in the Nerves community, so be sure to plug into this one!

    Our theme this season is working with Elixir, and joining in the conversation today is Brad Traylor from Podium. Brad shares his expertise in hiring and training for Podium, a position he is passionate about since it gives him the opportunity to work on the people and tech side of things. We begin by hearing a bit of Brad’s background, when and how he was first introduced to Elixir and the standout qualities that attracted him to Podium. He discusses the hiring process, including what he looks for in an engineer, why they don’t recruit much but rather work with referrals, the step-by-step of onboarding new devs and the resources he recommends to anyone in the industry.

    Today on Elixir Wizards we are joined by none other than José Valim, the inventor of Elixir! Coming from the Ruby on Rails world, José found his way to functional programming and we hear all about the evolution of his philosophy and thought process around the time of the creation of the language. He gives us some great insight into why functional programming is so appealing to him and the problems he wanted to solve by creating Elixir. We chat about other languages and his use of Erlang, Elixir's three biggest influences and some important characters in the story. José also shares a bit of personal, behind the scenes stuff about his schedule and how he tries to stay as productive as possible. We finish off the chat, talking about performance and the measures José has taken in this regard. For all this and more from a true Elixir wizard, be sure to tune in!

He explains some of this application and the functionality and improvement it offers and the big difference the machine learning models make to this work.
