The secret of Nix is the application of the common wisdom of memory management discipline in modern programming language design to the process of building and distributing software.
The payoff is, as with garbage collection in the original case, and immense leap in safety, productivity, and maintainability for software build and deployment systems.
Concretely, Nix and the ecosystem of tools built upon it and each other mean:
- configuration management that never drifts
- upgrades that can always be rolled back in seconds
- servers that don't accrue cruft
- software whose bill of materials comes for free
- an end to version conflicts
- packages which can always be bundled into a minimal container image in seconds
- build artifacts which turn out the same no matter where or when you build them
- software running as-needed, even locally, without having to be installed or manually cleaned up
- a single, simple language capable of defining your entire stack, from building individual assets to managing cloud infrastructure to deploying service-oriented systems
- an end to 'works on my machine' bullshit in their development environments *without* the inefficiencies of virtualization— even on macOS
- user-mode package management for supercomputers and mainframes
- the ability to boot into yesterday's workstation with two keystrokes at boot time
- a time machine for running obsolete software which can't build on modern systems
- a time capsule for software research being conducted today
- the largest, most up-to-date package collection in the world
and much more. The benefits and applications and extensions of Nix are so startlingly vast and diverse because ultimately, the Nix ecosystem is not an iteration on a tool— it's a renaissance. You should join it and start shedding obsolete problems.
Nix solves what Docker merely works around.
