Elixir: Power of Erlang, Joy of Ruby
summary
Claims Elixir puts a Rubylike syntax on the Erlang VM and gives practical concurrency: demos run in the IEx shell, use pattern matching and recursion to implement len, fib and map, add an ExUnit test, then build a pmap that spawns one process per element with spawn and receive and collects results. Shows hot-swappable modules, metaprogramming via parse-tree macros, and that the parallel pmap actually uses all cores; also notes a laptop CPU has about one billion transistors (~8.25M per mm²).
