    Why so? Do you work with lisp languages? I’ve been recently fiding learning [e]lisp a con since it’s basically a domain specific language. Only Clojure has a bit of commercial opportunities, but even then it’s better to learn JavaScript/TypeScript for its greater use cases. Also, if I wanted to play with functional programming I’d go Haskell, Lean, or even Shen.










  • It all began with Nix software build system and package manager; they needee a way to build, compile software in a reproducible way. That is, if it builds on my machine, it should build on yours too given some constraints. Then they build a whole package repository for such sofware or package definitions, Nixpkgs, that can be build or retrieved using Nix package manager. Nixpkgs grew to be a repository for enabling runnig an GNU Linux OS on it: NixOS. It is declarative in the sense you write what it should contain like packages and behaves like system services. For example, see https://git.sr.ht/~misterio/nix-config.

    Atomic in the sense that when you want to change system’s configuration or state, everything should suceed in that update, otherwise fails; it is everything or nothing. This enables storing previous and current system revisions, so can rollback to previous state.

    Nix plus things like flakes, nix shell, enables a build inviroment akin to containers, but much better, correct, and flexible.

    Haskell is just an ecossytem Nixpkgs support.
