It is important to us that the Elixir community keeps thriving, and one of the best ways to ensure this is by lowering the barrier to entry as much as possible. Livebook is helping to achieve this aim, and today we are lucky enough to be joined by its developer, Jonatan Kłosko. Jonatan is a young prodigy because while he is still at college, he is working closely with José Valim at Dashbit, and he can solve a Rubik’s cube in under five seconds! After hearing about his college thesis on evolutionary algorithms using Numerical Elixir, we jump into the story of how he met José and started building Livebook. He explains that Livebook is a web application for writing interactive and collaborative code notebooks for Elixir and we hear about the many features he is building into it. From there, Jonatan describes what he loves about Elixir, and we discuss how learning functional programming changes the way we code. Tuning in, you’ll also hear about a bunch of features that make Elixir so great, how its downsides are mostly solved by its extensibility, and some of Jonatan’s other hobbies that help him keep balance in his life. Be sure to sip on some Elixir with us today!
