Haven’t watched it yet, but looking at the table of contents and transcript - it looks like it would be a good intro for those who are brand new to Elixir.

I’d love to see an intermediate version, which gives a lot of advice about how to set up supervisors and work with all the other goodness that OTP gives us. Also, something that gives some advice on how to design and structure applications would be awesome. As someone who is a little beyond the basics, I find myself often wondering how I should lay out my modules, what things belong as genservers/agents, how to set up robust supervision trees, etc.

They do a free trial of 200 minutes/10 days which would be enough for that course

With Visual Studio Dev Essentials you get 3 months, that’s what I’m using
