Daily Drip has easily been one of the most helpful resources on my journey to better understand Elixir and the Phoenix web framework.
Taylor Dolezal Software Architect

With any language there are so many details to learn. What functions are built-in? How should I structure my code? What tools are available for improving my workflow? It’s rare to find one source that can answer so many of these questions, but DailyDrip does this and more for Elixir.
