    While developing elixir web apps sometimes we’ll find the necessity of generating encrypted tokens, these can be used in transactional emails (account confirmation, password resets, etc.) or for other purposes.

  • Server processes in Elixir

    Elixir is a functional programming language with built in concurrency based on the actor model, this creates an easy way to parallelize work as a side effect.
