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.

Nix is the ultimate DevOps toolkit
Thanks for the response!
> This is difficult to answer without knowing more details.
The situation specifically is the ROS ecosystem, where metadata is managed in these package.xml files:
https://github.com/ros2/rclcpp/blob/master/rclcpp/package.xm...
The federated nature of the ecosystem has led to a culture where it's very normal to be building dozens of these at once, in the same workspace together, often from multiple repos (the repo above has four in it). So there are several build tools which automate the work of examining a source workspace and building all the packages within it in the correct topological order, respecting build_depend tags. The newest of these tools (colcon) has actually made the package.xml optional in many cases, as it can examine CMakelists, setup.py, BUILD, etc, and discover for itself what the dependencies are.
Your "distribution" of ROS is formed by listing all the packages and repos in this big file, for which there is other tooling to manage pulling dependency sources, whatever: https://github.com/ros/rosdistro/blob/master/foxy/distributi...
Anyway, so the existing ROS/nix efforts (1) seem to basically consume all of this package/distribution metadata at once and generate a giant parallel structure of nix definitions (eg https://github.com/lopsided98/nix-ros-overlay/blob/master/di...), which I fear would be completely opaque to users and any system which required everyone to leave behind these existing workflows would be an immediate non-starter.
I think the ideal scenario (and what it would look like if I built this myself based on debs) would be that you could source the "base" workspace as usual (enter the nix-shell?), and check out source, build packages as usual with colcon, the usual workspace-building tool, but there'd be an extra plugin/verb/flag for it, which would make it build each package as a nix package instead of into the usual installspace. The verb would generate the nix definitions on the fly, and probably handle the invocation and build-parallelism side of it as well.

miasma
I don't know. Have been using colorbuddy for ages now and it has always done exactly what I want. I don't need the "instant reaload" that lush advertices, doing :source on the colorscheme file, does the same for me to preview changes instantly. This is my theme, in case you need something to start with: - https://github.com/pinpox/nixos/blob/main/home-manager/modules/nvim/lua/config/pinpox-colors.lua

Bluetooth headphones problem
I can't remember why I put that workaround in there, might not be needed any more. The above config is part of my dotfiles, I use my Bose blueutooth headphones by connecting them via the blueman-applet if the don't pair automatically

Including third party flakes in a NixOS (or Home Manager) configuration flake
Here is an example from my config : I'm using an external flake called "matrix-hook", which is a little tool I wrote and have put in a separate flake. It get's included here. I am then passing self to each of the nixosConfigurations here, this allows me to import the module from the external flake in the configuration.nix of the host where I want to use it.

NixOS for selfhosting?
Yep, I have two different modules with defaults for server and for desktop. Host-specific settings are set in the according /machines//configuration.nix file. Most stuff is modularized into modules that can be reuesed and enabled at will.

Nix-rice: rice your system with nix
Yep, I'm using the toJSON function already. The problem I had, was that not all applications use JSON as configuration format. Also the nix code gets very long, if you have to write the whole template as a string, which I find quite unreadable. Mustache is a pretty simple frequently used templating language, here is an example template that get's rendered by the nix code above.

Ricing with NixOS?
My system uses a uniform colorscheme defined here. Configs for all applications I use read that and use the same colors. The wallpapers are randomly generated by a tool I wrote, it also automatically matches the colorscheme. Icons and symbols are colored the same way for awesomeWM.

My neovim config with a colorscheme created with nix
In case you are interested I use this and this to generate colorschemes, awesome config and a matching wallpaper

Dumping Tmux
Check out wezterm it has replaced tmux for me. Very active development, fast and just the right amount of features for my taste. It is configured in Lua, so if you are doing that for neovim already, it's another plus. I use it in combination with awesomeWM. My (not very special) config is here if you need something to start with.
