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.

The Neat Programming Language
It runs on plain C ABI, so you can just define C functions as `extern(C)`, just as you would in D. But you can also use `std.macro.cimport` to import C headers directly. Check out the Dragon demo, https://github.com/Neat-Lang/neat/blob/master/demos/dragon.n... :
macro import std.macro.cimport;

Running the "Reflections on Trusting Trust" Compiler
Funny sidestory: The way my compiler ( https://github.com/neat-lang/neat ) used to build is, two years ago there was an initial compiler that was written in D. And every time you checked it out on a new system, there was a file with a list of breaking commits, and it would:
- git clone itself in a subfolder

Show HN: C3 – a C alternative that looks like C
Sure, but keep in mind it's pre-pre-alpha and the current released version is kind of outdated (ping me if you actually want to try it):
https://github.com/neat-lang/neat
This is more a D-like than a C-like, but it only breaks C syntax in areas where IMO C straight up made the wrong call, like the inside-out type syntax.
The thing I'm most proud of is the full-powered macro system, which is really more of a compile-time compiler plugin system.
A good example of a macro would be listcomprehensions: https://github.com/Neat-Lang/neat/blob/master/src/neat/macro...
You can tell it's just compiler code that happens to be loaded at project compiletime.
`compiler.$expr xxx` is itself a macro, that parses an expression `xxx` and returns an expression that creates a syntax tree that, when compiled, is equivalent to having written `xxx`. It's effectively the opposite of `eval`. In that expression, `$identifier` is expanded to a variable reference to "identifier".
So `ASTSymbol test = compiler.$expr $where && $test;` is equivalent to `ASTSymbol test = new ASTBinary("&&", where, test)`. (This shows its worth as expressions become more expansive.)
All in all, this lets you write `bool b = [all a == 5 for a in array]`, and it's exactly equivalent to a plain for loop. You can see the exact for loop at line 103 in that file. `({ })` is stolen from gcc; google "statement expression".

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...

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].
