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 Is Not a Low-level Language – Your computer is not a fast PDP-11
True. The code generated by https://cc65.github.io/ is pretty decent but there are a few places where hand-rolled assembler will perform much better when you need it. Although I've made things for 6502-based systems in C with this handy compiler (thanks cc65 contributors!).
Is there something intrinsic to how C handles addressing that makes segmented architectures more painful than they ought to be? Or maybe is there a language where segmented addressing is easier?
I hadn't really thought about it in a while. :)

How did people learn to make games in the 80s
There's tools like cc65 that let you write C code for the NES.

i need some serious help learing the VICE emulator for c64.
You can use any text editor for coding and the tutorial uses cc65 for compiling assembly to machine code.

Has anyone used LLVM/Clang to create modern NES games?
You can use cc65 https://cc65.github.io/ but because you are compiling it in a limit hardware the cc65 has its rules and recommendations to follow in order to get the most optimal binaries, and more specifically I read this when I made the "Pong" game for NES as a practice long time ago https://nesdoug.com/ , I hope it helps, happy coding!

My custom single board computer, 65c02-based with multitasking support
What assembler/tools did you use anyways? Personally I'd recommend ca65 from the cc65 C compiler utility. It's very powerful, open source, and kept updated (unlike a lot of ancient 6502 tools, like WDC's)

A Graphical OS for the Atari 8-bit
It really is a cool project. https://github.com/cc65/cc65
It provides some template configuration files describing different memory layouts. And provides common libraries for input/output.
There's also a LLVM fork for MOS: https://github.com/llvm-mos/llvm-mos
They've got some interesting hacks with ZeroPage memory and register allocation: https://llvm-mos.org/wiki/Code_generation_overview
Interesting if you geek out on that kind of research.
