A brief history of Erlang and Elixir

Telecommunications and the web worked in different ways for years: until recently, the former was all about latency, concurrency, and long-running connections, while the latter, with HTTP, was just about “hits” on ephemeral connections. But the web evolved rapidly, and the things that were important in telecommunications became important for the web, too. https://www.welcometothejungle.co/articles/history-erlang-elixir

Exop on StreamData

A story about how I was inspired by Andrea Leopardi’s talk “Property-based testing is a mindset” he gave at ElixirConfEU 2018 in Warsaw, Poland, and what is ExopData as the result of this inspiration.

Exop + StreamData = ExopData - a tool which helps you generate data and write property-based tests.


Easy Concurrent Locking for Erlang/Elixir

This is a tiny library I threw together as I realised it would be useful in a couple of scenarios. The source is in Erlang, making it easy to use in both languages, and has example usage in both.

My Advent of Code 2018 Recap


In this blog post, I wrote about what I learned from AoC 2018:

  • Stop Thinking, Start Solving (Don’t get paralyzed by complexity estimations)
  • Functional thinking (a.k.a Streams v.s. Recursion)
  • Don’t Use Processes for Encapsulation (To spawn, or not to spawn?)
  • Binary Search FTW
