I’m doing a 7-part screencast that deep-dives into how Elixir (yup, that’s elixir, not erlang) does processes.
Prerequisites are understanding Elixir syntax, content ranges from beginner to “ready to become and advanced Elixir programmer”.

Amazing series! Can’t wait for the following episodes.
Aetherus
I love it! And I did learn something from the series. Thank you.

This is awesome! Thank you!
However, I noticed that it’s recommended to run tasks under Task.Supervisor.. But in that case looks like it loses
$callersand Mox fails to define an expectation in the caller’s process and I have to:set_mox_globaland forget about running tests withasync: trueAny suggestion?

Haha you got ahead of me I will address that
my solution is that Elixir Std Lib should support that out of the box (and it would also be nice to have GenServers forward callers via an option too). If you absolutely must have a solution, I wrote this library: https://hexdocs.pm/multiverses/Multiverses.DynamicSupervisor.html
Note that a Task.Supervisor is actually a DynamicSupervisor

Hm. I took a second look at it and Task.Supervisor.start_child should be setting callers correctly:
