159: Langchain with Elixir and Safe Ecto Migrations
Thinking Elixir Podcast
Elixir 1.16: A New Type System
ElixirConf US 2023 keynote talks on how to work around type system. Andrea Leo party has released V 2.0 of Corsica, which is a library for handling cores requests. If your AWS RDS database fail after upgrading it's probably due to a SSL certificate validation problem. And this will eliminate some warning messages about how Ecto couldn't verify certificates or something like that.
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.
