is a pretty good place to start.
I also recommend the book, "Erlang and OTP in Action." Don't fall into the trap of trying to reinvent the things OTP provides.
But a question: It says it's using Erlang 13B. Do you recommend using a newer version, or trying to compile/finding an old binary version of 13B? (I mean, is Erlang 16 compatible with 13, or they tend to break things?)
(I'm sure I'll find this out eventually when I start the tutorial, but it's always good to know this kind of things beforehand)
The thing is, elixir is really just erlang with some extra features (which are really compelling to me) and some syntax changes that make it much more readable to non-erlangers. (or at least, I believe it would.)
But secretly, you're learning erlang. And afterwards the transition between the two will be seamless (Because they're really the same language.)
