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.

LKM Relocation ressources
As far as I know, kernel modules are ordinary relocatable ELF executables, so the best resource will be the ELF specifications. The ARM-specific parts can be found here.

Cortex M7: get MSP using inline _asm algorithm checkup
Yes, that would be the case when your code's entry-point executes, and from then on it is your responsibility to maintain the alignment. It has nothing to do with AHB. This advisory has some examples of what can go wrong if your stack isn't 8-byte aligned. The alignment does not make much of a difference in your little function, but it's something to keep in mind as you write more complex code.

Raspberry Pi Pico: What is this obfuscated code(?) doing in its boot ROM?
Normally you'd save more than just PC as AAPCS (https://github.com/ARM-software/abi-aa/blob/main/aapcs32/aap...) mandates stack to be aligned to 8 bytes for "public interface" functions. But this is is not a "public" function so it's fine to only save lr here.
"bx lr" is only used on it's own when the function doesn't call another function (altering lr), and doesn't need to save any registers.
If you see pop {lr}; bx lr then that's code that's being compiled to explicitly support Armv4 (e.g. Arm7TDMI)

What can I expect to happen if I print a character above CHAR_MAX?
The Arm Procedure Call Standards have "Arm C and C++ Language Mappings" sections that all say char is an "unsigned byte".

This Week in Rust #412
eabi: many pages in this official ARM repository define it as "An ABI suited to the needs of embedded, and deeply embedded (sometimes called free standing), applications." It seems to be the name of an ABI, or maybe the ABI, that code compiled for ARM chips is expected to use? Except there's also AEABI, the first A stands for ARM, and that's something different? ARM's naming conventions confuse me endlessly.

PyPy Project looking for sponsorship to add support for Apple Silicon
> Apple changed some things that impact PyPy, like the register uses and ffi calling conventions.
I thought everyone who used 64-bit ARM used ARM's AAPCS64 (https://github.com/ARM-software/abi-aa/blob/master/aapcs64/a...), so the register usage and FFI calling convention should be the same as on Linux and Windows. What did Apple do that would affect the PyPy JIT?

Create a Custom GitHub Action in Rust
If you haven't dipped your touch-typing fingers into Rust yet, you really owe it to yourself. Rust is a modern programming language with features that make it suitable not only for systems programming -- its original purpose, but just about any other environment, too; there are frameworks that let your build web services, web applications including user interfaces, software for embedded devices, machine learning solutions, and of course, command-line tools. Since a custom GitHub Action is essentially a command-line tool that interacts with the system through files and environment variables, Rust is perfectly suited for that as well.

Why Does Windows Use Backslash as Path Separator?
Here's an example of someone citing a disagreement between CRT and shell32:
https://github.com/rust-lang/rust/issues/44650
This in addition to the Rust CVE mentioned elsewhere in the thread which was rooted in this issue:
https://blog.rust-lang.org/2024/04/09/cve-2024-24576.html
Here are some quick programs to test contrasting approaches. I don't have examples of inputs where they parse differently on hand right now, but I know they exist. This was also a problem that was frequently discussed internally when I worked at MSFT.

I hate Rust (programming language)
> instead of choosing a certain numbered version of the random library (if I remember correctly) I let cargo download the latest version which had a completely different API.
Yeah, they didn't follow the instructions and got burned. I still think that multiple things went wrong simultaneously for that experience. I wonder if more prevalent uses of `#[doc(alias = "name")]` being leveraged by https://github.com/rust-lang/rust/pull/120730 (which now that I check only accounts for methods and not functions, I should get on that!) so that when changing APIs around people at least get a slightly better experience.

Show HN: Fancy-ANSI – Small JavaScript library for converting ANSI to HTML
Recently did something similar in Rust but for generating SVGs. We've adopted it for snapshot testing of cargo and rustc's output. Don't have a good PR handy for showing Github's rendering of changes in the SVG (text, side-by-side, swiping) but https://github.com/rust-lang/rust/pull/121877/files has newly added SVGs.
To see what is supported, see the screenshot in the docs: https://docs.rs/anstyle-svg/latest/anstyle_svg/
