"Learn at least one new language every year" - The Pragmatic Programmer - David Thomas, Andrew Hunt With this statement in mind, this year I started learning Elixir in my reduced spare time. The chatbot is just an excuse to apply my skills to Elixir and to determine the power of this amazing language. Join me for a hands-on session to discover and learn the Elixir ecosystem: the language, the toolbelt and what the Erlang VM provides to Elixir developers. Sources: https://github.com/wilk/dpc18bot
