Language servers are an important part of modern developer tooling. Mitch Hanberg has made this his new focus with gen_lsp, a generic language server behaviour that he then implemented a Credo language server on top of. Yes, that's right, Credo! We learn what that means and what his new elixir-tools Github organization is intended to do. Listen to Mich share his vision for what Elixir dev tools could be like! We get an update on his Temple project, an alternative to Phoenix templates, we learn about an existing Elixir formatter plugin that may reformat code more to your liking and more!

Fly.io: Fly.io is a great place to deploy your next Phoenix application! Check them out!

Rust is a popular lower level language and the community has created a number of libraries to solve different problems. We talk with Jason Stiebs, a Phoenix Core Team member, about how Elixir and Rust can play well together. Jason wrote an article about how he leveraged an image processing library available in Rust by using the Elixir Rustler package. We talk about how Rustler works through NIFs, and we learn how easy using Rustler has become. It's great to understand that we have a powerful escape hatch like Rustler for those times we need it. We also get Jason’s insights into the Phoenix project and talk about the importance of improving the developer experience when a LiveView crashes and more!

Recently Livebook had its first launch week. We met with Jonatan Kłosko, the developer behind most of the exciting new features, to learn what some of these additions are, how they actually work and what's coming with the new Teams feature. Jonatan shares some of his favorite unsung features and where the new apps ability may go in the future. Livebook is an important community project and it's fun getting a deeper look inside!

Hauleth (Łukasz Jan Niemier) takes us deeper into the Elixir and Erlang loggers. He recently closed a 3.5 year old bug on the ElixirLang Github project by unifying the Elixir logger with the logger that Erlang got in OTP 21. We touch on the history, why it took so long, what we should think of the new logging levels, and what the original goals were that he set out to achieve. We also get an introduction to the new logging filters and handlers along with some peeks into future Erlang logging features that may still be yet to come in Elixir!

We go deeper on the Sobelow library, a security-focused static analysis tool for Elixir and Phoenix apps. We talk with Griffin Byatt, the creator, and Holden Oullette, the new maintainer. We learn how and why the project was created, how it works, what it can and can't do, and how to use it in CI pipelines for continuous scanning. Sobelow is a cornerstone project in the community that checks a critical box for certification requirements which means we get to use Elixir when it might otherwise be a hard sell. Join us as we learn more about the project and the people behind it!
