Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Devbox 0.2.0: Automatic Nix Installer, Plugins, and Background Services
Thinking about it like rpm/deb is where you're getting hung up. Think of it more along the lines of npm, but for your OS (or just your profile in the case of nixpkgs+home-manager).
At the most trivial level, you can set up some packages to install [1][2]. You'll generally come out ahead of classical package managers if you do that and nothing else.
Nix also acknowledges the configuration issue. Think of this like copying some config files using a dockerfile. You can either use literals[3], or use the nix language to generate the config [4] (provided that someone has created the required projection from nix to config).
What this ends up becoming is a single git repo with your entire system setup. My repo gets a bit fancier: I have my home desktop (currently Nixos, but it distrohops a lot), my personal laptop running Ubuntu+intune+nixpkgs for work, and then my work Mac machine (which I am aiming to get rid of). The single repo contains nix configs for all 3, and shares config where appropriate.
I really need to write a blog post about Nix in 2023. The main issue with getting started right now is that the installer requires some convincing to use flakes (not to mention that flakes are disabled by default), and you really should be using flakes.

About using Nix in my development workflow
Using these with home-manager is also really simple. You simply enable nix-direnv[0], and then `use flake` in your envrc[1]. Finally, set up your flake.nix with a dev shell[2] (I'm definitely going to take a look at numtide's devshell).
You'll also need flakes and the nix command enabled first [4] (add that line to `/etc/nix/nix.conf` if you aren't using nixos).
Why use flakes? Mostly because it has a lockfile: there's a really good chance that "works on my machine" is "works on my team's machines." Flakes are also much cleaner than vanilla Nix.

How Google got to rolling Linux releases for Desktops
The nice thing with flake-based NixOS is that it's trivial to cherry-pick unstable onto a stable base. I do a bunch of that in my nixconfigs: https://gitlab.com/jcdickinson/nix

How do multiple versions of the package internally work?
BTW: I personally use direnv with nix-direnv. This basically works by setting your shell with proper tooling when you enter the directory.

I have a few beginner question, what is the difference between nix shell/env and what is the difference between flakes/home-manager?
I'm not sure what you mean by nix env, maybe you are referring to nix-direnv?

Just a reminder to make sure Garbage Collection is running
Although currently I'm using direnv + nix-direnv. Keep in mind that direnv has builtin nix support which is very basic and doesn't do any caching. So you still needs this add-on to preserve roots.

What do you install with configuration.nix and home manager
I distinguish between system level things and user level things, even though I don't really have different users on my machine. I install the bare minimum number of packages + a lot of different drivers in the configuration.nix, and desktop and editor related things in HM. For development environment, I have environment per project using mkShell and https://github.com/nix-community/nix-direnv, which allows you to switch to the specific environment once you cd into the directory. (Although I do have python installed globally with some commonly used packages such as numpy, so I can just start python and write something when I need to, without creating an environment)
-
How do YOU use your PKMS?
I further make my software projects so that when I click a link I go into an environment pre-loaded with their dependencies so dropping in/out of projects is always frictionless. I do this with the reproducibility guarantees of nix, along with glue like nix-direnv and envrc-mode to direnv.

Minimal approach for python devel environment with flake
Personally I use nix-direnv. No longer the need to run nix develop or nix-shell. By setting up a .envrc with either use nix or use flake it will automatically install all the packages from default/shell.nix or flake.nix

Nix and envrc
Direnv is installed using the nix-direnv installation instructions under "Via configuration.nix in NixOS". I read some recommendations that envrc.el is a better alternative then direnv.el, and after some testing I have to agree. (envrc-global-mode) is enabled in my config. This works perfectly with a normal emacs instance.
