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.

Writing a Simple Garbage Collector in C (2020)
Boehm GC is mentioned in the article: https://github.com/ivmai/bdwgc
- Boehm-Demers-Weiser Garbage Collector
- Sound like some C stuff
-
Tricking the garbage collector with unsigned longs?
This stuff is all implementation dependent. The Boehm garbage collector has been wrestling with the compilers for years regarding these issues, see its development repo.
-
Any good resources to learn how to implement Automated Reference Counting in C99?
Any kind of automatic GC is going to be rare in C. The only automatic garbage collection that I am aware of is the BDW garbage collector abet that uses mark and sweep instead of reference counting https://github.com/ivmai/bdwgc
- Why isn't there a GCed variant of C++ that'd be functionally like Java, but with C++'s syntax?
-
Small (EXPERIMENTAL RESEARCH) project I made to add a reference counter GC to clang (specifically clang, will change) C
My dude have you heard of Boehm GC

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...

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...
For example,

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].
