A journey to Syn v2, a better Erlang & Elixir Process Registry and Group manager

By Roberto Ostinelli / November 18, 2019 / 3 Comments

For those who don’t know it, Syn (short for synonym) is a global Process Registry and Process Group manager for Erlang and Elixir that I’ve written a few years back. It has been around for some time now, and it has served me well on many occasions. Through the years, I’ve built up a series of considerations and ideas for improvement, and now the time has come to put all of these back into Syn.

Syn v2 has been rewritten from the grounds up, and I’d like to share the reasoning and the architectural choices behind this work. Since Syn is written in Erlang, the few portions of the code here below will show Erlang syntax. Don’t let that discourage you if you are an Elixir developer though, as the same principles apply.

Modern Erlang for Beginners: my course

By Roberto Ostinelli / March 13, 2019 / 2 Comments

I remember when I first started learning Erlang, many years ago. There was the fundamental Programming Erlang book by the late Joe Armstrong, the official Erlang documentation, some various books but what really helped me was a screencast from Kevin Smith sold on the Pragmatic Bookshelf’s website.

I am a visual learner, which means that it is much easier for me to learn with videos or by pairing with other people. So, after those years I decided that I wanted to add my little contribution to the Erlang courses that available out there.

I’m pleased to say that as per today my course is live on The Pragmatic Bookshelf. I hope it will help out those who are seeking to enter this fantastic world, or those Elixir programmers who want to understand Erlang better.

EDIT (Apr. 17, 2023): my course was retired from PragProg on Apr. 21, 2020 and moved to Udemy, but is now retired from Udemy as well.
