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 Template Library
This is cool! I've seen this C-with-templates used in the past with ".X" headers but haven't used the technique myself. Having something based on STL might help people to center on one library instead of constantly reinventing collections in C (which I've also done for some structures, and open sourced though I don't recommend using it: https://github.com/nitrogenlogic/nlutils).

OpenBSD System-Call Pinning
Well since https://www.openbsd.org/ still says
> Only two remote holes in the default install, in a heck of a long time!
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.
- Une nouvelle mise à jour de Systemd permettra à Linux de bénéficier de l'infâme "écran bleu de la mort" de Windows, mais la fonctionnalité a reçu un accueil très mitigé

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.

"<ESC>[31M"? ANSI Terminal security in 2023 and finding 10 CVEs
Actually, I got it wrong, too many vulnerabilities in flight. They did fix it: https://github.com/openbsd/src/commit/375ccafb2eb77de6cf240e...
