username3··on Why tail-recursive functions are loops
> I wrote up a detailed blog post about tail call optimization in Elixir/Erlang and its performance. The TLDR; sort of is that none tail call optimized recursive functions (body-recursive) can be faster and more memory efficient than TCO functions. This is something that I never thought before, that TCO is always faster seems to be a common misconception. My example is also not contrived - it’s an implementation of map.

username3··on Ash Framework – Model your domain, derive the rest
Add an attribute to a model, run `mix ash.codegen`, it creates migrations for you.

You don’t need to create a context file with CRUD functions for your Repo.

See the example repository for the Ash book.
