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.

HFS Origins: The Turbo File System (2017)
I think NeXT might've written an HFS Standard reader or something, but they used the Apple code for HFS+ so it ended up as a hybrid.

Windows 11 Insider Preview — Rust in the Windows Kernel
Mach message passing and objc message passing have no relation. I don’t think xnu contains much if any objc.

Apple releases a Game Porting Tool, based on open-source platform Wine, which can translate DirectX 12 into Metal 3, a potentially massive step for Mac gaming
here is the kernel source (they have branches for each individual macos release with its darwin kernel ver, macos 13 is ver 8792.xx.x for instance): https://github.com/apple-oss-distributions/xnu

Apple’s new Proton-like tool can run Windows games on a Mac
Apple does plenty of open source stuff. Safari's browser engine, Swift, libdispatch, the XNU kernel used by iOS and macOS, etc. And macOS is generally packed with open source things, like the default shell, zsh. Also, Metal actually predates Vulkan, so Vulkan was definitely not established when they started focusing on Metal. Yeah, they probably should consider supporting Vulkan now, but it's nothing to do with open source. The main beneficiaries of Apple supporting Vulkan would be people porting closed-source games.

Programming from Top to Bottom - Parsing
You can never mistake type_declaration with an identifier, otherwise the program will not work. Aside from that constraint, you are free to name them whatever you like, there is no one standard, and each parser has it own naming conventions, unless you are planning to use something like LLVM. If you are interested, you can see examples of naming in different language parsers in the AST Explorer.

Look ma, I wrote a new JIT compiler for PostgreSQL

Actually, it's implemented in LLVM for years :) https://github.com/llvm/llvm-project/commit/a98546ebcd2a692e...

C++ Safety, in Context
> It's true, this was a CVE in Rust and not a CVE in C++, but only because C++ doesn't regard the issue as a problem at all. The problem definitely exists in C++, but it's not acknowledged as a problem, let alone fixed.
Can you find a link that substantiates your claim? You're throwing out some heavy accusations here that don't seem to match reality at all.
Case in point, this was fixed in both major C++ libraries:
https://github.com/gcc-mirror/gcc/commit/ebf6175464768983a2d...
https://github.com/llvm/llvm-project/commit/4f67a909902d8ab9...
So what C++ community refused to regard this as an issue and refused to fix it? Where is your supporting evidence for your claims?

Rewrite the VP9 codec library in Rust
Through value tracking. It's actually LLVM that does this, GCC probably does it as well, so in theory explicit bounds checks in regular C code would also be removed by the compiler.
How it works exactly I don't know, and apparently it's so complex that it requires over 9000 lines of C++ to express:
