159: Langchain with Elixir and Safe Ecto Migrations

Mark and David share what's caught their interests and focus. Langchain is a popular framework in JS and Python communities for building services that knit together different services enabling people to quickly build impressive demos. Mark talks about the parts of Langchain that interest him and how he's been building ways for Elixir apps to play in that space too. We also catch up with David’s job change, moving, and talk about his ideas around using Oban for managing data migrations in a new way.
