The article is about why the author switched from Arch Linux to NixOS, a Linux distribution based on the Nix package manager. The author explains the benefits of Nix, such as:
- Reproducibility: Nix packages are built from pure functions that specify their dependencies and configuration, so they can be reproduced on any system with the same results.
- Atomicity: Nix operations are atomic, meaning they either succeed completely or fail without affecting the system state. This makes it easy to roll back to previous versions or configurations if something goes wrong.
Isolation: Nix packages are installed in isolation from each other, avoiding conflicts and allowing multiple versions of the same package to coexist.
- Declarativeness: NixOS allows users to declare their system configuration in a simple and readable language, and then automatically generates and applies the necessary changes.
The author also compares Nix to other package managers, such as pacman, apt, and Homebrew, and shows how Nix solves some of the common problems they face, such as dependency hell, impurity, and manual intervention. The author concludes by saying that Nix is the new Arch, because it offers a similar philosophy of simplicity, flexibility, and control, but with more reliability and elegance.
