What is Nix package manager?
Nix package manager solves the problem of inconsistent, incomplete package state by enforcing complete state by default. Nix provides atomic upgrades and rollbacks, side-by-side installation of multiple versions of a package, multi-user support, per-user profiles, and improved conflicts resolution. It also has powerful user environment management which makes it easy to work with multiple profiles.
What is Ruby?
Ruby is not just a programming language, but an entire philosophy about programming. It makes programming fun, productive, and rewarding. Most programs consist of code that needs to be organized into functions. And so most Ruby programs consist of classes and modules containing useful functions for interacting with the real world, operating on text, working with objects, creating GUIs, doing system administration tasks, building web applications… you name it. Ruby is at its heart a toolkit for accessing existing libraries like OpenSSL and providing something like Visual Basic style syntactic sugar to make working with them fun.
