That is really exciting!
more content is coming, but i took a break to produce a week on neural networks with elixir that's coming out next week.
It starts with the beta for Phoenix 1.3 and is still being updated on a quasi regular basis. You can join the Elixir slack channel and there is a specific Firestorm channel to catch regular updates.
Also, is course complete or is there more content coming?
Does the Firestorm screencast start off using 1.3 or is it still going from 1.2 -> 1.3.
