Consider signing up for the Elixir Radar2019-11-08
If you have an interest in the Elixir ecosystem I think the Elixir Radar newsletter is useful resource. I followed it even before I had any real opportunity to work with Elixir or Phoenix but it helped in keeping me up with conference talks, interesting blog posts and assorted other stuff. I recommend it.
They are running a referral campaign until the 30th of November. I could get some Pragprog books which would be fun. If you want to help with that use this referral link.
I've also found Elixir Weekly to be a useful newsletter.
