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.

SectorC: A C Compiler in 512 bytes
The bootstrap seed, https://github.com/oriansj/bootstrap-seeds/blob/master/POSIX..., is a tiny interpreter that takes a much larger program written in a special-purpose, bytecode-based language. This proceeds in turn once or twice more--special purpose program generating another interpreter for another special-purpose language--until you end up with a minimal Scheme interpreter, which then can be used to execute a C compiler program.
All of this is incredible work, but a minimal C-subset compiler in under 512 bytes seems like a unique achievement.

Ken Thompson: Reflections on Trusting Trust (Turing Award Lecture)
There is also live-bootstrap which uses a similar bootstrap chain to Guix (stage0 -> Mes -> tcc -> gcc), but without needing Guile/guix-daemon binaries etc. The whole thing starts with just a 357-byte binary seed (source)!

Zig is now self–hosted by default
Yeah, it's a binary blob, but it's small enough to be easily auditable. Anyone with some knowledge of x86 assembly can read the annotated version [1] and verify that it does what it claims (which is to convert ASCII hex with comments into binary).
You're right, it also requires a Linux kernel, and of course, you also have to trust the hardware you're running it on. Still, it reduces the amount of stuff we have to take for granted as trusted, which I think is a good thing. (I'm not involved in the project, just an admirer).

stage0-posix was ported to RISC-V
stage0-posix just gained initial support for RISC-V (64-bit). It starts with 392 byte hex assembler, 361 byte "shell" and bootstraps simple linker (hex2), macro assembler (M0). Then it builds cc_riscv64 RISC-V compiler written in RISC-V assembly and uses it to build simple C compiler written in C (M2-Planet). Then it builds a few extra utilities (cp, mkdir, untar, ungz, sha256sum, chmod)

Reproducibility
From a security point of view the only thing that gentoo users need to achieve similar levels of security is a bootstrapped compiler from a known good seed. The source code is already deterministic by definition. After that all you need is a compiler bootstrapped via something like https://github.com/oriansj/bootstrap-seeds which can be independently verified. It would probably be useful to be able to have independent bootstraps arrive at the same binary output for a compiler, but probably only as an option. Ultimately way less work for the same level of security.

Show HN: I made a better Perplexity for developers
It's "Zig" not "Zag". https://ziglang.org/ Zig is under heavy development, but there's a single page https://ziglang.org/documentation/0.12.0/ that is a reasonably comprehensive source of truth about the current state of the language.

Bun - The One Tool for All Your JavaScript/Typescript Project's Needs?
NodeJS is by no means a slow runtime, it wouldn’t be so popular if it was. But compared to Bun, it’s slow. Bun was built from the ground up with speed in mind, using both JavascriptCore and Zig. The Bun team spent an enormous amount of time and energy trying to make Bun fast, including lots of profiling, benchmarking, and optimizations.

ntdll.dll!RtlUserThreadStart()
There are valid reasons to use APIs from NTDLL. Where I disagree with zig#1840 is the idea that it is always better to use NTDLL versions of API. Every other software ecosystem uses the standard Win32 APIs and diverging from that without a good reason seems like a good way to have unexpected behavior. One concrete example is most users and programmers expect Windows to redirect some file system paths when running on WOW64. But this is implemented in Kernel32, not ntdll.

live-bootstrap - Use of a Linux initramfs to fully automate the bootstrapping process
Nim - Nim is a statically typed compiled systems programming language. It combines successful concepts from mature languages like Python, Ada and Modula. Its design focuses on efficiency, expressiveness, and elegance (in that order of priority).
