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.

Our Roadmap for Nix
The ‘flake-utils’ readme is a pretty good jumping off point: https://github.com/numtide/flake-utils
I have this or that nitpick with FL and FLP but overall it’s very solid stuff. FLP is a little more “magical”, and that’s not always the best starting out, but you really can’t go wrong with either.

Rust Environment and Docker Build with Nix Flakes
We added two inputs, the first is nixpkgs which lets us specify which version of nixpkgs we should use. There are many thousands of packages in the nixpkg repository, and they are updated often so here will use the unstable branch. We also added flake-utils which helps us generalize the flake to support multiple systems, not just Linux.
-
Getting Started Using Nix Flakes As An Elixir Development Environment
The inputs is how you can import external sources of other flakes into the flake project you have. In other words, any project you may need or tools required to get started, this is where you will define their source. Example below is using the standard nixpkgs and a tool called flake-utils, which provides a set of functions to make flake nix packages simpler to set up without external dependencies.

Flake equivalent to `nix-shell --pure`?
I'm not sure what nix-shell --pure does, but is it equivalent to using a flakes.nix in your projects? Ie i use https://github.com/numtide/flake-utils and direnv to replicate the old shell.nix with a Flakes setup. Per project i have a flakes.nix and a flakes.lock, so it feels just like my old shell.nix setup, but using flakes instead.

Workspace Management With Nix Flakes: Jupyter Notebook Example
A Nix Flake is just an object - check out those surrounding curly braces. This object has two keys, inputs and outputs. The inputs are where we define the flake's dependencies and where to find all the tools we use. This one has two, nixpkgs and flake-utils. Each of these just points to a GitHub URL, and if you follow those links, you'll see each repo provides its own flake.nix. The outputs of each remote flake get piped into the inputs of my flake, so we can use what they provide.
-
How to transition from shell.nix to flake.nix?
You can easily transition your shell.nix (and default.nix) to a flake-based one by using flake-utils and flake-compat. The former is actually unnecessary, but I would recommend it for typical project environments. Unless you have an impure dependency, this transition would be easy.

Is there a way to use flakes to nix run emacsgcc?
Flakes can provide different types of things: - some flakes provide applications that you can nix run, - some flakes provide functions that you can import (e.g. https://github.com/numtide/flake-utils), - some flakes provide overlays to use with nixpkgs (e.g. that emacs-overlay you posted).

Nix – A One Pager
So, its key features are:
1. domain-specific: designed for conveniently creating and composing derivations. This reason alone already justifies a new language, or an embedded domain-specific language (such as the Guile/Scheme for guix), or a mix of both (Starlark, the build language of Bazel embedded in a restricted Python-variant).
2. purely functional: this ties well into the philosophical backing of Nix the package manager, which aims to be purely functional, also known as hermeticity in other build systems (Bazel).
3. lazily evaluated: similar to other build systems (including Bazel), so that you can build only what you need on demand.
4. dynamically typed: this one is controversial. Being dynamically typed—in other words, not developing a type system—gets Nix out of the door first. But users often complain about the lack of proper types and modularity. There are experiments to address this, such as Nickel (https://github.com/tweag/nickel).
It is understandable that a one-pager may not have space for the whys.

10 Ways for Kubernetes Declarative Configuration Management
Nickel:Nickel is a straightforward configuration language aimed at automatically generating static configuration files. Essentially, it's akin to JSON with the addition of functions and types.

Nickel is a programming language. While HCL is just a configuration format, so not really comparable.

Announcing Nickel 1.0, a configuration language written in (and usable from) Rust
As for 'providence', I suppose you meant provenance :) it's been delayed because this was less critical for 1.0 to decide on or to implement (as it: it doesn't break backward compatibility in any way to add this feature in the short term), but this is very much on the roadmap: Issue #235. That's a must-have in a language with merging like Nickel.

Rewrite it in Rust: Kubernetes
Have you considered using a different language for templating? this could be a BIG selling point. Some good ones are cue-lang (though I haven't seen support for rust), kcl or nickel-lang.
