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.

NixOS + Haskell best practices circa March 2023

Pulling themes from a git project: the nix way?
Flakes work. An alternative is niv which was once popular and provides a good developer experience.
-
What are the biggest Pain Points with NIX? And what makes it worth the pain?
Essentially you can just think of it as a standardized default.nix/shell.nix with built-in Niv integration.

Our Roadmap for Nix
I agree that the FP part is not the only issue. It's that the community feels a bit more academic/I'll fix this for myself in the way that works best for me.
You can indeed achieve some reproducibility with Docker. It's tricky though, as you'd have to pin exact package versions of software. If you'd `FROM ubuntu:$VERION`, and would run an `apt-get update`, you're not guaranteed to get the same software.
Nix is like ZFS, as that it breaks the wall between two previously distinct area's. Those being building software, and installing/configuration software on your OS. It's quite different from the snapshot-everything methodology that Docker uses. Yeah, one can split in multi-stage images etc, but than you'll be keeping track of which dependencies need to be moved between the stages yourself, in a manner that cannot be abstracted away, so you're doomed to repeat the same patterns over and over again.
People also state that LVM + ext3 is more than sufficient compared to the complexity of ZFS. They miss out on the fact on how much more fine grained solutions are possible with ZFS.
I've used niv [0] before flakes arrived, and am actually still using that instead of flakes. The experimental nature of them has scared me away from them, as I'm not daily involved in this ecosystem at the moment.

Simplest way to set up neovim
You can use something like Niv to manage additional sources. I use it to fetch some Emacs packages, for example ligature.el. Then you update the package using $ niv update.
-
Unstable vs Stable channels
One thing that made this easier was switching from using Nix channels to explicitly pinning my dependencies with Niv. I honestly never fully understood how channels worked, and it's just much nicer to have everything specified in my Git repo. The exact commit of Nixpkgs that I'm using is in my sources.json file, so "reverting" just means checking out an older commit of my configs from Git then running nixos-rebuild switch. If I were redoing my dotfiles today I'd probably use Nix Flakes rather than Niv, but I suspect that Niv is still an easier option to get started with.

Remove unused niv packages
Does someone know of a way to remove unused pinned packages via [niv](https://github.com/nmattia/niv)?
-
How to downgrade single package?
Pin nixpkgs, and version control it. If you're using flakes, then just version control the flake.lock alongside your configuration. If you're not using flakes, you can use niv to easily pin nipxkgs, at the expense of some boiler plate.
- Compiling emacs is killing me

Ditch Your Version Manager
This... This is laughable. How do I install ruby 2.6.8? Oh, there's no ruby_2_6_8, because of course there isn't. And this could be difference between a secure system and all your base are belong to us.
And they call this reproducible builds?
And that's before getting into the ridiculous
--- start quote ---
All the software that we installed depends on the specific version of the nixpkgs channel that we installed on our system [whose only version is a commit hash in a git repo]
--- end quote ---
So you need an extra tool [2] for, quote, "painless dependencies for Nix projects."
Yes, sure. I'm definitely ditching my version managers in favor of this tool, that hasn't solved these issues in 18 years of its existence.

Fish and nix develop question
I have a wrapper function that just maps to dev to make life easier: https://github.com/dmadisetti/.dots/blob/template/dot/config/fish/functions/develop.fish
-
Possible to make a machine independent NixOS configuration/flake?
Never fully got it to work, so I just encrypt my secrets when I build my isos: https://github.com/dmadisetti/.dots/actions/runs/5055636638/jobs/9072093945
-
Hardware configuration in nix flake dotfiles?
I have multiple files for each machine based on hostname. I have CI strip my config of all system specific information for general distribution. For reference: https://github.com/dmadisetti/.dots
-
Using current flake setup with WSL2
I build a wsl image: https://github.com/dmadisetti/.dots/blob/template/nix/machines/wsl.nix
- Diving straight into flakes with no channels?
-
how to store secrets needed at install time
What I do: Keep secrets in a separate git repo as a flake, and have a stub flake, that can be overridden: https://github.com/dmadisetti/.dots/tree/template/nix/spoof
-
Rice NixOS?
My dots
-
(maybe) ex arch user need some help to understand
I have a script that will symlink my dotfiles in (github:dmadisetti/.dots/setup.sh), because you also end up with weird RO permissions if you do it through Nix. I think this is fine. It also means that you aren't stuck with Nix
-
Have a shell command in configuration.nix that runs on nixos-rebuild
The way I manage multiple systems is with a wrapper: https://github.com/dmadisetti/.dots/blob/template/dot/config/fish/functions/snix.fish
-
Arch user, convince me to hop to Nix
The only thing that is semi manual is setting up disks on first install (something you'd still have to do with arch). You can still script that: https://github.com/dmadisetti/.dots/blob/template/scripts/run-install.nix.sh
