It might be overwhelming to dive into the Nix world, but this little glossary should help refine your understanding of the tools you might encounter when starting your journey.

UPD: I wrote one more short article to articulate why I prefer nix over non-nix setups in general: https://dev.to/alexander_shagov/why-use-nix-even-on-macos-786

Nix Package Manager – The core tool that allows declarative and reproducible package management.

NixOS – A Linux distribution built entirely on the Nix package manager. It's better to start with nix package manager alone before switching to NixOS completely.

Ruby on Rails: Rethinking Service Objects

In the Ruby on Rails community, service objects have gained popularity as a way to encapsulate business logic and keep controllers and models lean. However, there's a growing trend of misusing service objects, particularly those with "-er" or "-or" suffixes. This article aims to shed light on poorly implemented service objects and provide guidance on creating more effective, domain-focused alternatives.

Many developers tend to name their service objects with suffixes like -er or -or, such as ArticleCreator or UserAuthenticator. While this naming convention may seem intuitive, it often leads to a procedural style of programming rather than embracing the object-oriented nature of Ruby.
