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.

3rd Edition of Programming: Principles and Practice Using C++ by Stroustrup
For a single file script, nix can make the package management quite easy: https://github.com/NixOS/nixpkgs/blob/master/doc/languages-f...

NixOS Is Not Reproducible
Yes, Nix doesn't actually ensure that the builds are deterministic. In fact it works just fine if they aren't. There are packages in nixpkgs that aren't reproducible: https://github.com/NixOS/nixpkgs/issues?q=is%3Aopen+is%3Aiss...

The xz attack shell script
I'm not familiar with Bazel, but Nix in it's current form wouldn't have solved this attack. First of all, the standard mkDerivation function calls the same configure; make; make install process that made this attack possible. Nixpkgs regularly pulls in external resources (fetchUrl and friends) that are equally vulnerable to a poisoned release tarball. Checkout the comment on the current xz entry in nixpkgs https://github.com/NixOS/nixpkgs/blob/master/pkgs/tools/comp...

Debian Git Monorepo
NixOS uses a monorepo and I think everyone's love it.
I love being able to easily grep through all the packages source code and there's regularly PRs that harmonizes conventions across many packages.
Nixpkgs doesn't include the packaged software source code, so it's a lot more practical than what Debian is doing.

From xz to ibus: more questionable tarballs
In this specific case, nix uses fetchFromGitHub to download the source archive, which are generated by GitHub for the specified revision[1]. Arch seems to just download the tarball from the releases page[2].

GitHub Disabled the Xz Repo
True, but irrelevant -- _some packages_, _somewhere_, do depend on xz, which, if built, requires pulling the source from GitHub (see the default.nix: https://github.com/NixOS/nixpkgs/blob/nixos-23.11/pkgs/tools...)
It's not the vulnerability that's a problem right now (NixOS was protected by a couple of factors) but rather GitHub's hamfisted response.
That is the problem.
What are some alternatives?
reflex - Interactive programs without callbacks or side-effects. Functional Reactive Programming (FRP) uses composable events and time-varying values to describe interactive systems as pure functions. Just like other pure functional code, functional reactive code is easier to get right on the first try, maintain, and reuse.
asdf - Extendable version manager with support for Ruby, Node.js, Elixir, Erlang & more
obelisk - Functional reactive web and mobile applications, with batteries included.
Home Manager using Nix - Manage a user environment using Nix [maintainer=@rycee]
Elm - Compiler for Elm, a functional language for reliable webapps.
git-lfs - Git extension for versioning large files
reflex-dom - Web applications without callbacks or side-effects. Reflex-DOM brings the power of functional reactive programming (FRP) to the web. Build HTML and other Document Object Model (DOM) data with a pure functional interface.
easyeffects - Limiter, compressor, convolver, equalizer and auto volume and many other plugins for PipeWire applications
spack - A flexible package manager that supports multiple versions, configurations, platforms, and compilers.
waydroid - Waydroid uses a container-based approach to boot a full Android system on a regular GNU/Linux system like Ubuntu.
