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.

Which assembly to learn for a macbook air m1 ?
Depends on the cpu, as the other user said for M1 processor you'll use ARM64 Assembly, I found this repo with tutorials for Assembly ARM64 https://github.com/below/HelloSilicon

Learning ARM64 Assembly. Need help!
I've just started learning Assembly on my M1 Mac and I was suggested to use this github repo as a reference.

Using ADR in ARM MacOS
I've been trying to learn ARM assembly for my m1 MBA by following along with this book and accompanying GitHub page updating it for Apple silicone. Unfortunately, I am running into the error "unknown AArch64 fixup kind!" when I try to use ADR or ADRP (LDR is not allowed on Apple silicone afik). So, If anyone knows why this error is popping and/or how to fix it, that would be awesome.

Making NetBSD Multiboot-Compatible (2007)
TIL there is a version of UNIX for PDP-7, and PDP-7 did not have MMU, therefore UNIX by definition do not require MMU, and that version of UNIX had been archeologied in a runnable form on GitHub[1]

Where to find the original Unix image file?
I've never heard of a copy being used outside of the original authors' site. However, it can be built from source code and run on a PDP-7 emulator. https://github.com/DoctorWkt/pdp7-unix.

Apple M1 Assembly Language Hello World
Well first of all I was wrong -- the PDP7 did have syscalls, I'm just bad at reading PDP7 assembly and missed the dispatcher. Curiously, it looks like the sequence is entirely different, although there could be some magic that makes the order different than it appears at first glance.
https://github.com/DoctorWkt/pdp7-unix/blob/master/src/sys/s...
It's all just guessing, but I figure the explanation is much simpler -- for PDP11 UNIX, they just kept using the same syscalls up till V7 / 2BSD, and there should have been a sort of "rolling release" binary compatibility. For the VAX, the first port (32v) probably just retained the original numbering since there was no reason to deviate from it, which colored 3BSD and 4BSD, hence {Net,Free,Open}BSD and Darwin and friends.
Worth pointing out that several versions of Linux have rather different syscall tables. 32 bit ARM and x86 are more-or-less matches, with ARM differing on a few early syscalls, while 64 bit ARM and amd64 differing quite dramatically. The old ABI for 32bit MIPS also matches, but both the n32 and n64 ABIs use slightly variant syscall tables. PowerPC 32/64 bit is also a close match, although it has some impedance (I think it matches closer to AIX by design)
At the end of the day, I think the similarity is mostly a mixture of coincidence, system developers being influenced by their bootstrap system's syscall tables, and no real reason to change them up. No reason to not change them, either, since it's pretty trivial to use different dispatch tables for different types of processes, like how the BSD's handle other-OS compat.
