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.

Vulkan Video Extensions for Accelerated H.264 and H.265 Encode
Whilst Firefox may support hardware video decoding, Mesa since March 2022 disables patent encumbered codecs by default[1], and distributions such as Fedora and OpenSuse do not explicitly enable these patent encumbered codecs to avoid possible legal problems. Even Gentoo (built from source code by the user) requires the user to explicitly enable a USE flag (proprietary-codes) to use patent encumbered codecs.[2]
The thought process is that AMD, NVIDIA, Intel and the likes are not providing a patent license with their hardware.[3] They are instead just supplying part of an overall system that together with operating system kernel, display manager software, video player software, etc allows the decoding and encoding of patent encumbered video files. Open source software projects and distributions are concerned they'd be found to be infringing patents by enabling a complete solution out-of-the-box. Hence they put some hurdles in place so that a user has to go out of their way to separately piece together the various parts to form a complete system capable of encoding and decoding patent encumbered codecs.

I like gentoo's package deprecation process
Thank you! I don't live in git and this helps! Normally under gentoo I shouldn't have to. This actual git https://github.com/gentoo/gentoo (as opposed to the gentoo browser view) plus this "checkout the commit" should get me much further. ... And probably deserve some space in the gentoo docs.

OpenBSD System-Call Pinning
Well since https://www.openbsd.org/ still says

I'm assuming not, but I could always be mistaken.

From Nand to Tetris: Building a Modern Computer from First Principles
> building a cat from scratch
> That would be an interesting project.
Here is the source code of the OpenBSD implementation of cat:
> https://github.com/openbsd/src/blob/master/bin/cat/cat.c
and here of the GNU coreutils implementation:
> https://github.com/coreutils/coreutils/blob/master/src/cat.c
Thus: I don't think building a cat from scratch or creating a tutorial about that topic is particularly hard (even though the HN audience would likely be interested in it). :-)

OpenBSD – pinning all system calls
> I don't know how they define `MAX`, but I'm guessing it's a typical "a>b?a:b"
Indeed: https://github.com/openbsd/src/blob/master/sys/sys/param.h#L...
> Then `SYS_kbind` seems to be a signed int.
It's an untyped #define: https://github.com/openbsd/src/blob/master/sys/sys/syscall.h...
I believe your whole analysis is correct, that running an elf file with an openbsd.syscalls entry with .sysno > INT_MAX will allow an out-of-bounds write.

tmux causing ANSI color-response garbage on attaching?
I can reproduce it. And this is the commit that causes the issue: https://github.com/openbsd/src/commit/d21788ce70be80e9c4ed0c52c149e01147c4a823

Sudo-rs' first security audit
This doesn’t really change your conclusion, but I think that’s the wrong file. This is the real doas afaict: https://github.com/openbsd/src/blob/master/usr.bin/doas/doas...
Still just a tidy 1072 lines in that folder though.
I spent 5 minutes staring at your file trying to understand how on earth it does the things in the man page, but of course it doesn’t.

OpenBSD: Removing syscall(2) from libc and kernel
OpenBSD developers are making serious effort to kill off indirect syscalls, the base system is completely clean, take a look at the work Andrew Fresh did to adapt Perl. He write a complete syscall "dispatcher" or emulator for the Perl syscall function so that it calls the libc stubs.
https://github.com/openbsd/src/commit/312e26c80be876012ae979...
The ports tree is also being cleansed of syscall(2) usage, until they're all gone.
msyscall, pinsyscall, recent mandatory IBT/BTI, xonly. OpenBSD is making waves, but people aren't really seeing them yet.
