    ⇒ A Measurement Study on the Adoption of Pledges and Unveils in the OpenBSD Operating System

    The paper presents a longitudinal measurement study on the adoption of the pledge and unveil system calls in OpenBSD. These system calls are used to sandbox programs and libraries. Given a dataset covering 19 releases, many programs and libraries were modified to use the system calls already before their introductions in official releases.

    … bzfs is a CLI for reliable ZFS snapshot replication using zfs send/receive and SSH. It is meant for the boring-but-important corner of infrastructure where "probably replicated" is not the vibe.

    The main bit in this release: bzfs can now drive recursive resumable ZFS stream packages …

    Hi! So I have a small VPS with OpenBSD on it and I anticipate that disk space will not be enough, so my question is, if I know that I will never compile the whole system from source, can I just repurpose the space allocated to /usr/obj and /usr/src and mount those partitions where they're needed? Or is this a really really bad idea? It would free up about 10GB (out of 40GB total).

    https://www.phoronix.com/news/Linux-Sched-Ext-Restructured

    Quoting Torvalds:

     create mode 100644 kernel/sched/ext_arena.c
 create mode 100644 kernel/sched/ext_arena.h
 create mode 100644 kernel/sched/ext_cid.c
 create mode 100644 kernel/sched/ext_cid.h
 create mode 100644 kernel/sched/ext_types.h

    Please don't do this disgusting thing.

    There's a reason we have subdirectories: it's to group files together and separate them out

    Using name prefixing instead of directories is disgusting and wrong. If you have this many random sched-ext files, it damn well should be cleaned up and not be this kind of mess.

    I've pulled this, but under protest. Proper hierarchical filesystems have been available since 1965.

    It's blunt, but it did begin with the word "Please".

    His use of the word "disgusting" is, ahem, slightly at odds with this recent observation:

    … Já o Linus sempre foi mais polido, político e mais comercial.

    Translated by Reddit:

    … Linus, on the other hand, was always more polished, political, and more business-minded.

    Today felt pretty decent, or at least comparatively, and maybe only for ~22% of the hours of consciousness...

    ~0530 -> 22:42 ... just need to save this one file to the NFS share... and...

    Seems today is a "No NFS for assholes" day, very astute.

    So no NFS for me; still an asshole, sure sure (only sometimes), but no NFS? So unfair. LDAP/FreeIPA why are you the way that you are? 😕

    Maybe if I threaten the LDAP VM with its existential annihilation, and replace it with a RADIUS + TACACS + NIS (the OG right there, nothing better than a Trainwreck deep into the warm, loving arms, the secure embrace, the Inner Self unleashed - unbounded - staring directly into the eyes of `Network Information Service +` ... NIS+ YES!

    @tribblix @ptribble

    I read that NIS+ was removed from Solaris 11.x (hopefully this is incorrect), in which case... what are your thoughts on the subject? There's no Windows, no SMB, it's just Solaris, Tribblix, OmniOS, Gentoo, {Rocky 9/10, OEL 9/10}, and of course... FreeBSD, also one or two little nodes w/ NetBSD and a Xen box too... lots of boxes.

    So.. NIC+ on Tribblix getting some traction if I decide to reprovision this new workstation w/ the latest instead of Sol 11.4... the video card situation is either a P2200 or A4000, and while those work on Solaris I've not been able to find the right combination of drivers to get these two working with Tribblix. Are those going to work or maybe a RTX 2080?

    NIS+ got removed from Solaris back at the end of 2009. So it got removed from OpenSolaris and thus illumos, as that was before the fork. This was announced long before. As a heavy NIS+ user at the time, we were somewhat dismayed to read the announcement. Sun said it would be no problem, LDAP was a superior replacement. We actually tried LDAP, and to call it an unmitigated disaster would be far too generous. Apart from the excessive hardware requirements, endless bugs, woeful performance, and lack of basic functionality, there was an almost total lack of administrative tooling. My understanding is that NIS itself is also slated for the chop in Solaris 11 at some point. In theory, you could reinstate NIS+ in illumos - we have the whole commit history so reverting 6874309 wouldn't be so bad. Whether you could get it to work properly is another matter.

    Good for you! I've lost count of the number of problems with Nvidia on Linux, whereas AMD's support is simply excellent—or is becoming so… If the situation is better with FreeBSD, so much the better. On OpenBSD, it's better to have an AMD than an Nvidia!

    hardware corruption?! Sometimes, errors occur when the USB connection is physically disturbed. Other times, there's no obvious explanation. I might be hands-off, with my cat nowhere near, at the time.

    Port knocking is mostly a bad idea. But people keep wanting to do it, for some false sense of security. If you don't consider it a security control but a way to keep garbage out of your logs, it might be valid. In my case I'm using an old USG Pro 4 running OpenBSD as my firewall and I'd prefer to avoid writing stuff to the logs, as I'd prefer the flash not to wear out sooner than needed, definitely not thanks to background radiation on the internet.
