> Dave Thomas, the author of Pragmatic Programmer and Programming Ruby (arguably the book that helped Ruby grow pre-Rails), has written a great book titled "Programming Elixir"

I bought this ebook when it was first released. The level of care Dave has given to it is astounding. I believe he's released at least 10 significant updates to it as the language has evolved.

Maybe he said somewhere on the book's marketing page that he was going to be doing that, but if he did, I missed it. Extremely pleasant surprise.
