Definitely agree some of the "using erlang libraries in Elixir" guides on the internet are 10/10 confusing. It'll be good to have this as a resource on Google in the future! I spent quite awhile figuring out how to implement a SSL TCP server, with PSK and only a subset of cipher suites... a good long while.

Also related, I really like the `active` (GenServer example in this post) socket approach because then you're just writing a TCP server that acts like any erlang message provider. Of course there's some difficulties related to that but it makes the code very straightforward to understand and manage.
