• Show HN: Why is the Amiga so beloved in the demoscene? (2023 essay)
  1 project | news.ycombinator.com | 6 Dec 2023

  Lots of Amiga concepts live on today with DragonflyBSD.

  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)
  2 projects | news.ycombinator.com | 6 Jun 2023

  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.

  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.

• Comparative BSD cheatsheet?

  FreeBSD, NetBSD, and OpenBSD all have a ksh(1) descending from pdksh, while DragonFlyBSD does not implement any ksh.
