No project is perfect from the start. The real problems are very complicated. While something seems simple and fits perfectly, it may not be. I want to present the most critical and unchanging aspect of each project.

A blog is a great way to learn from your past. You can be your own teacher. Let me show you why I started my blog.

Companies operate in an uncertain environment. Uncertain technology is certainly not something that will interest them. What makes companies decide to use Elixir language?

We have some environmental variables in almost every Elixir application. They change the behavior of the system. They even allow you to reduce variables to be hard-coded somewhere in the depths of the code. I will show how you can use environment variables better.

Based on Erlang VM, Elixir is often limited by a virtual machine’s capabilities or the language itself. One such limitation manifests itself in weak optimization of System.get_env/0 function.
