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.

BTFS (BitTorrent Filesystem)
Just the other week I used Nix on my laptop to derive a PXE boot images, uploaded those to IPFS, and netbooted my server in another country over a public IPFS mirror. The initrd gets mounted as read-only overlayfs on boot. My configs are public: https://github.com/jhvst/nix-config

Use nix-shell or systemPackages
You should look into configuring your neovim with home-manager. This wraps the tools needed for various language servers in a way that solves your concern. Upside is that now you can also move the whole neovim configuration into servers etc., if you prefer that, just by importing your neovim configuration. I have done this in my configuration.

NixOS 22.11 “Raccoon” Released
Plugging my own thing here, but I have been experimenting with a Nix configuration for gaming only. My configuration is here (for Nvidia, which does not work without tinkering as AMD does) : https://github.com/jhvst/nix-config/blob/main/nvidia.nix
First, this is a whole system specification. This means that executing this on Nix will build you a whole OS image. You can build the image if you have Nix by running the first line on file. You can also use Docker with the instruction on my README: https://github.com/jhvst/nix-config
Back to elaborating on the Nix file from the gaming perspective. First, we have the overlays. These are like patches to the packages, and really useful for gaming because it allows building important packages like mesa from the source tip. This is particularly useful when new games or GPUs are released. Same thing for wayland: Nvidia and its proprietary drivers need some patching, but it's possible to get wayland (and sway) to work this way.
Then, I have taken the reproducibility of Nix to a next step in my opinion, and made the system stateless. This means that it runs from the RAM. It is easy to create installation media like kernel, initrd, and rootfs because you have all the steps to create the distribution. This means that here, Nix works as a meta-distro like Gentoo, on top of which you develop your own. Running from the RAM means that theoretically, if you have a working config, and two people with different hardware runs it, then they should have the same experience. If you look at ProtonDB, you often find that some people claim that game X works on their machine with drivers and mesa of Y and Z, but there is no way to copy their configurations because it's certain that the user has made some stateful changes which they have forgotten hence left undocumented, which is the reason it works for them. If everyone would be using Nix, you could reproduce their system and possibly fix your own, but this is not tractable with most OSs.
If you like to test my changes, you can read more about my approach here: https://github.com/NixOS/nixpkgs/pull/203750
For testing I distribute Nvidia as documented here: https://github.com/jhvst/jhvst.github.io/blob/main/ramdisk.m...
However, I have developed it bit further: if you manage to get into an iPXE shell, you can write `boot -a http://boot.ponkila.com/menu.ipxe`, then select the second option which is Nvidia (proprietary drivers), and with some waiting you will get into a shell prompt to which you can write `sway --unsupported-gpu`, which will launch sway. Cmd+Enter opens a prompt to which you can write `steam`, which will open Steam. Then, you have to mount some drive on another shell with `mount`, and add this as a Steam library via Steam's UI. Then you can play games. I use this on AMD and I have been very happy.

NixOS on Raspberry Pi 4 & enabling Ethernet over USB
You will need to have a DHCP server which has to be configured with ARM 64 bit file name option to point to the efi/boot/bootaa64.efi in the TFTP server alongside option called UEFI HTTPBoot URL which has to point to the RPI_EFI.d file from the ipxe project builds. Unfortunately, I have no idea how to apply the DHCP settings unless you happen to run pfSense, which has the option under DHCP server settings. If you manage to do this some other way, you can then add a file called autoexec.ipxe to the efi/boot folder. You can generate the autoexec.ipxe file by running the following script, for example: https://github.com/jhvst/nix-config/blob/main/minimal.nix (the command to run it is in the first line of the file).

Use nix-shell or systemPackages
Rustup works as is. Though note that Nix supplants all such toolchain installers such as Rustup, nvm, etc. I.e. instead of Rustup there is fenix.

Can rustc generate identical binaries, with the same hash, from the same souce code?
Fenix ( https://github.com/nix-community/fenix ) has tooling or picking a specific toolchain or even nightly. You can then build with the following nix code:
- Fenix: Rust toolchains and rust-analyzer nightly for Nix

Annoucing fenix monthly, Rust toolchains updated 1st of every month
Fenix monthly is a new branch similar to the main branch, but only updated on the 1st of every month, for cases where you want to use rust nightly but don't need it to be updated very often.
- Fenix - Rust toolchains and rust-analyzer nightly for Nix
- Show HN: Fenix – Rust toolchains and Rust-analyzer nightly for Nix

Why this overlay doesn't work?
The issue should be fixed once the nix-vscode-extension and fenix patches are merged. The latter will happen automatically once CI passes.

Have a few questions about NixOS
4. I would suggest Mozilla's Rust overlay or fenix or similar instead of Rustup - that would be more of the "Nix-way" to acquire the toolchain and you can still manage multiple versions. Not sure what the Ruby equivalent is, I don't do Ruby.

Oops, I Did It Again...I Made A Rust Web API And It Was Not That Difficult
To follow along, you'll need a stable Rust toolchain. See the install page for instructions to install rustup for your platform. You should prefer this method to your distribution's package manager. If you're a NixOS freak, I recommend fenix.
