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.

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.
-
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.

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.

What is the upside of using Flakes instead of niv?

Flakes aren't real and cannot hurt you: using Nix flakes the non-flake way
The project uses this overlay: https://github.com/nix-community/emacs-overlay
What that means is if something is broken in Emacs, the community will fix it, and all I need to do is run `nix flake update` to grab the latest commit and then `nix run .#build-switch` to alter my system. Easy.
Thanks for the heads-up on the 404s! I've fixed those links.
In re: to org-agenda, I don't use that as much anymore. But I heavily, heavily using org-roam w/ org-roam-dailies everyday to build my own networked graph of notes. For tasks, nowadays I just use simple docs for projects and Asana to keep a catalog of everything.

NixOS&(Home-Manager) Flake/Overlays Help
Im a newish NixOS user, Ive used it like 20 times before but always quit because I couldnt debug errors, trying not to give up for the 20th time this time lmao; so Ive been trying to learn how to use overlays & flakes for a couple of days now. The ones I want to use/enable are: - Emacs-Overlay - Spicetify-Nix
- My First Impressions of Nix
-
Which package manager should I use?
Nix offers the same advantage through the use of emacs-overlay. Besides, Nixpkgs contains more Linux packages than any other distros. Depending on the user's needs, Nix is another option.
-
It looks like the kellyk Emacs PPA is no longer maintained. Are there any alternatives?
You can use this overlay to get the latest https://github.com/nix-community/emacs-overlay
-
Will any emacs package manager let me audit packages before installing them?
Depending on your goals, emacs-overlay is also worth a look.

How to use Emacs 29 Tree-sitter?
You can install Nix on your mac and use https://github.com/nix-community/emacs-overlay/, which supports all the existing tree-sitter-based major modes OOB.
-
Emacs 29 is nigh What can we expect?
Its great to see both eglot and tree-sitter being merged. However, I am unhappy about the state of 'emacs configurations/distributions' right now. I have been using Doom Emacs, but the development is pretty much stalled there [0], and I don't think there is any distribution that is keeping up with these cutting-edge features (compared to the NeoVim ecosystem, let's say). Somehow it feels like I was seeing a lot more activity about Emacs configurations two-three years ago.
> Compile EmacsLisp files ahead of time
Ooh, this is interesting. Hoping to see a derivation in https://github.com/nix-community/emacs-overlay soon.
[0] I am not complaining though as Doom was the main author's personal config from the get-go. I am just pointing out a void.
