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.

Reflecting on the Shake Build System
> hermetic == sandbox which only contains declared deps
Yes, exactly. It also can include other deps like networking. A perfect hermetic build will (for most of the build process) not have access to the network.
> I assume bazel implements this via containers?
Sort of. Bazel's code predates "containers" by ~6 years. Bazel is the build system used at Google (sprinkle on a large amount of asterisks here).
> Also, IMO, this only provides a false sense of safety unless you archive absolutely everything that's inside the sandbox.
Yes, that is what a Bazel monorepo does. You can also include your language's runtime and standard library as part of the build process. See Dropbox's repo for more details on how they do this with Python: https://github.com/dropbox/dbx_build_tools
Some more details about what Google does are available here: https://opensource.google/docs/thirdparty/#
Essentially, everything is built from source (more asterisks here). Since everything is built from source using Bazel you can guarantee that at a certain view of the source repository you can build a reproducible copy of all software in the repo (more asterisks).
One other nice property is you can guarantee that all software in the repo is using a compatible version of each dep: https://opensource.google/docs/thirdparty/oneversion/
The downside is that if you want to upgrade a library that has a breaking change this requires you update a lot of code. The upside is that doing that isn't actually that hard with the tooling available and you can guarantee that you can link together any two libraries in the repo (more asterisks) and have the build succeed without any dep version conflicts. Since you can do this some langauges with runtimes (like JVM language) can see massive speed boosts because they only need to compile changed libraries and can run a `java -cp ... your.jar` to load up deps. You can check out rules_docker for some examples of how this can be used.

Nix: The Breaking Point
I don't think so. The article is probably intended for the Nix community, so the author doesn't need to convince HN that something is going on. If as an outsider you are interested then you need to look into it yourself, the community has no obligation to make their internal conflicts legible to the outside world.
As an outsider myself, it certainly looks like something is going on as more than 20 Nixpkg maintainers left in a week: https://github.com/NixOS/nixpkgs/issues?q=label%3A%228.has%3...

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].
