   The last attempt I'm aware of was over a decade ago now, at the time there was some interest in building the system (kernel+userland) with pcc (Portable C Compiler), ultimately LLVM/clang won out in the end. https://und

   OpenBSD's X distribution (xenocara) is based on X11R7.7 + updated components, it's just a historical naming convention. Other systems have merged X into /usr or /usr/local, OpenBSD kept the install prefix. https:&#

   The final fate of self-hosted QNX was super unfortunate, and poor decision making on the part of RIM/Blackberry. QNX completely dropped support for self-hosted QNX Neutrino development after 6.5 [0], and stopped distributing installati

   One of my favourites, archive filenames containing a colon ':' character cause GNU tar to execute a command, historically rsh (remote shell), but thanks to the Linux alternatives system, is often aliased to ssh. This was added man

   OpenBSD removed the mincore(2) syscall your table lists as "best" 3 years ago. https://marc.info/?l=openbsd-cvs&m=154723400730318&w=2

   musl/dietlibc target the Linux kernel. There are no alternative libc implementations for *BSD, unlike Linux the system provided libc is the only libc that matters.

   kinda indeed. As far as I can tell Intel PKU was only on Server-CPUs/Xeons until at least the 11th Gen (only later models?), and AMD Zen 3. OpenBSD doesn't support protection keys, in any case.

    There was some work done on XOM (eXecute-only-memory) for arm64, but on at least x86 there isn't a separate page table bit for just read permissions, so there's no way[0][1] to express R^X, PROT_EXEC without PROT_READ is not poss

    Well then here's a few more keywords for you. 'jet-lag', 'travel'. Hackathons tentatively take place in airport lounges.

    I played through "Forest's Secret" by bynine which is a non-violent game, reminiscent of classic adventure games.

    Ah well. At least the code/drivers remain in the CVS Attic, perhaps they might be useful for a future NetBSD port. Fun write-up.

    OpenBSD actually had a port to similar Freescale MPC834x boards, but it was discontinued in 2015. https://www.openbsd.org/socppc.html I feel like the author of this post, given their interests and history, might be amused b

    sysclean is not mentioned in the release notes, there is a small mention in the upgrade guide which states it's a package. There's some ongoing discussions that imply it probably shouldn't even be mentioned there. https:&#x2

    Apparently it was inspired by similar work done on DragonFlyBSD for select(2), unfortunately I cannot find any details about their implementation.

    The webzine mentions the OpenBSD 7.1 release, but is a separate story and a worthy glance into the goings on in the OpenBSD community.

    OpenBSD includes firmware it can permissively redistribute, for example as of 7.1, OpenBSD developers spent many months working with Realtek to change the firmware license for rtwn(4), urtwn(4) and rsu(4) wireless devices so that it could b

    OpenSSH and LibreSSL are OpenBSD projects. OpenSSL has nothing to do with OpenBSD.
