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.

How do I deploy a configuration to a machine with an existing hardware-configuration.nix?
Use flake-utils-plus to easily define multiple systems in flake.nix.and then use the --target-host flag of nixos-rebuild to deploy it remotely.
-
Have a shell command in configuration.nix that runs on nixos-rebuild
If you're trying to handle multiple systems with one config a flake is a significantly better option. I would personally recommend looking at flake-utils-plus and specifically this example config.

Best way to manage multiple home manager configs for both NixOS and non-NixOS systems using flakes?
I looked at some past threads / examples and saw people recommend flake-utils-plus, but after reading the examples I don't understand how I would get home-manager on Darwin or Ubuntu.

Nix: Taming Unix with Functional Programming
Depending on your specific needs, the channelsConfig (modify arguments passed to Nixpkgs) and overlay tooling in flake-utils-plus may be adequate: https://github.com/gytis-ivaskevicius/flake-utils-plus/tree/...

What to do...
For flakes you don't have to set up everything manually there are helper libraries, I use flake-utils-plus.
-
How shall I install a package not found at https://search.nixos.org/packages?
Converting to flakes is not that hard if you use a good library. The documentation is other people's configs, really.
-
I made a thing you can load in Nix repl to get variables from your NixOS configuration
Neat! I've been using flake-utils-plus's implementation until now. https://github.com/gytis-ivaskevicius/flake-utils-plus/blob/master/lib/repl.nix
-
How to use a patched nixpkgs locally?
I use flake-utils-plus based configuration to apply patches on top of nixpkgs where overlays don't suffice.
-
How to downgrade single package?
You can then use the input directly. I am using flake-utils-plus which has this nice overlay-builder:

oh oops, I think I was intending to type "crowd source" but I really met "crowd fund".
I do want to finish my FreeBSD cross PR, but is is hard. We already have NetBSD working, including building the kernel, so I think it is better to start there.
I opened https://github.com/cleverca22/not-os/issues/16 because I think that would be the absolute easiest first step, with the fewest moving parts. But I don't know how kernels, even Linux, are packaged into bootable thingies at all.

What does the minimal version of NixOS consist of?
I also found this: https://github.com/cleverca22/not-os

NixOS 21.05 Released
It's like an OS that has builtin salt/ansible/chef/puppet.
Because Nix language describe the OS instead of what to change/configure it's superior to these tools, and solves the problem that supposedly same machines are drifting apart.
For example if in the CM you tell it to install a package, then change your mind and remove the entry that does it. The package will remain installed.
With NixOS if you remove the package from configuration, it's gone.
I personally really like Nix's building capability. For example I can use it to generate a minimal docker container. It requires some knowledge, but I can also modify compilation options in dependencies (like remove unneeded functionality).
It looks like there's also an option to similarly build lightweight OS images[1]. I haven't tried it yet but looks cool.
Yes, it's extremely powerful once you truly understand Nix.
There are efforts to improve documentation, but it still is lacking (I think the biggest problem is that Nix is so big, not just the OS but it can be utilized as a build system).
Just with NixOS is not exactly clear how can you for example build your custom image.
I think https://nix.dev/ is approaching the documentation from the right direction.
There are also many pieces that people built that you need to find.
For example some things that I found accidentally:
* https://github.com/matthewbauer/nix-bundle
* https://github.com/cleverca22/not-os
Unfortunately those side projects often have even worse documentation.

Is it possible to deploy configuration as code?
You might want to check out https://github.com/telent/nixwrt and https://github.com/cleverca22/not-os as solutions with similar goals. The former is a promising but yet-unfinished way of using Nix to manage a router, while the latter is a similar way of using Nix to generate an immutable OS image.
- Is it possible to replace systemd with runit?
