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.

Comparative BSD cheatsheet?
Another interesting list is https://github.com/jpdasma/unix-cheat-sheet, although it doesn't seem to be entirely correct (it says OpenBSD has mount_nullfs, but I can't find anything similar in 7.1).

Show HN: Why is the Amiga so beloved in the demoscene? (2023 essay)
Lots of Amiga concepts live on today with DragonflyBSD.
https://www.dragonflybsd.org/
And it’s shockingly performant (on par with Linux, sometimes even better), given the tiny development team.
Messaging passing, etc are core Amiga ideas that exist today only in Dfly.

FreeBSD at 30 years: Its secrets to success
Love FreeBSD but ...
Really wish there wasn't a split between FreeBSD & Matt Dillon 18-years ago (DragonflyBSD), since DragonflyBSD is so strong and yet FreeBSD hasn't benefited from it's innovations.

The Linux kernel will fix some peculiar argv usage in execve(2)
There are three things I expect to find in mailing list discussions before going off and reading them:
* Someone suggests that the kernel return EINVAL for null or zero-length argument vector. Someone else then comes up with a mad but very real mainstream program that relies upon the system call succeeding.
* Someone points out that the SUS requires that argv[0] be non-null. Someone else tries to weasel a difference between "shall" and "should", overlooking the SUS rationale that the leeway given is in the string contents, not that it is permitted to be outright null.
* Someone suggests in all seriousness that this behaviour be retained for historical compatibility.
For reference:
* FreeBSD just returns EINVAL for a zero-length argument vector, https://github.com/freebsd/freebsd-src/commit/773fa8cd136a57... . This came from OpenBSD.
* A null argument vector has been EFAULT in FreeBSD since 2004, when someone noticed that the manual disallowed this, https://github.com/freebsd/freebsd-src/commit/7700eb86e7740c... .
* DragonFly BSD has been fixing up a zero-length argument vector by adding in a dummy non-null argv[0] since 2005, https://github.com/DragonFlyBSD/DragonFlyBSD/commit/66be6566... . It introduced EFAULT for a null argument vector at the same time.
* Illumos has returned EFAULT for a null argument vector since at least the point when it went open-source in 2005.

A modern replacement for Redis and Memcached
I find it remarkably rude to name your business product the same as a long-established open-source project.

I think I may have outgrown computers
Ay wanna give dragonflybsd a go? Link
- Would the BSD operating system benefit from a microkernel architecture.

BSD operating systems, which is your favorite?
DragonflyBSD: Forked from FreeBSD 4.8; amongst other things, provides HAMMER, a "high performance filesystem with built-in mirroring and historic access functionality", and virtual kernels.
