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.

C-Macs – a pure C macOS application
The linked project doesn't use any ObjC files at all. SDL2 has a bunch of Cocoa files[1] so you did use Cocoa even if unknowingly.

Revert "video: Prefer Wayland over X11 (take 2)"
Correct. It's explained here:
https://github.com/libsdl-org/SDL/pull/9345#issuecomment-201...
XWayland has special hooks into the compositors that normal wayland clients don't get.

BBC Basic returns on multiple platforms, open sourced
If that app ran in a 640x480 mode, memory accesses would be just as fast as the VGA applications 25 years ago, correct?
I think there's a lot more going on than that. Here's SDL's current pixel access code:

Games! How they write code for SDL (+ interview with the creator)
We use the code examples throughout the article. The ellipsis characters "...." in the code were added by the author of the article. You can find the source files on the official GitHub of libsdl. In addition, each fragment has a reference to a specific area in the code. By the time this article is published, many errors will have already been fixed thanks to the issues we opened (for example, here and there). However, the links in the examples point exactly to the code you see in this article. Not only do we enjoy teasing developers but we also like making their projects a little bit better!

Chip8 emulator
It's not that difficult, I recently started learning to use graphics APIs myself. OpenGL is for linux, etc., directx for windows and vulkan for all platforms. I read through a bunch of forums yesterday and decided to go for vulkan (here is a link to the sdk) for my next small projects because it can run on all platforms. I would recommend to watch a basic tutorial series (like this one) for the graphics api itself to get an understanding of whats going on. And on top of that I use SDL2 for eventhandling and ImGui for the graphical user interface. Here is a link to a guide for setting up vulkan on your platform in case you would go for it.

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
> There is one way to make the LLVM JIT compiler more usable, but I fear it’s going to take years to be implemented: being able to cache and reuse compiled queries.
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:
