This is a preview of things to come in Serenum Release 5. A new update for my OS that I am relentlessly crunching on to complete.https://samhsmith.com/serenum/

Not my video. Just felt it fits here for more discussion. Personally I do like the idea of more/better sandboxing for apps.

    I don’t understand this guy’s argument at all. First of all, he isn’t using any shell that I know about, he seems to have invented his own, and the command line arguments he uses are specific to his own shell. He doesn’t explain how these command line arguments work in terms of POSIX system calls, so I can’t follow along with what he is actually doing. As far as I can tell, these are security issues with his own software, not with Unix or Linux.

    If you are worried about file mutability, you can use ZFS or BTrFS or BCacheFS. All of these filesystems have a snapshot function, so if any changes (e.g. file encryption by ransomware attackers) are made you can reboot and roll back the changes, unless the attackers figure out a way to get root access and delete your snapshots. But if an attacker has gained root access to your computer, that is a much more serious issue and not really in the scope of filesystem security or file mutability.

    The snapshot and rollback feature also exists in NixOS and GuixOS, where your operating system kernel and all software installed is part of a snapshot that can be rolled back, if the system becomes unbootable, you can rollback from within the GRUB boot loader. Again, all software installation is managed by a service that runs for you at root level so you never need sudo to install software, and the software you install never effects any other user or the operating system. So the only way to hack this is to gain root access and alter the content of the Guix or Nix “store” database with malicious code, but again, root access is a much bigger issue than what we are talking about.

    So yeah, the argument stated in this video makes no sense to me.

      So yeah, the argument stated in this video makes no sense to me.

      I kind of took it that in traditional way of installing things apps can read/write pretty much anywhere in the users home. I also did not follow his shell example.

      Yeah, watched a few vids with this guy…not interested. He doesn’t believe in FOSS, he talks about Linux, MacOS, and Windows all being dumpster fires, but his solution is to build his own OS from scratch, using Latin…and run it on a Chinese RISC-V board that he is charging people $200 and doesn’t open source the hardware or software.

      Has hardcore TempleOS vibes, the difference is that this guy seems to take himself and his idea way too seriously. And his defense of why he thinks all modern mainstream OSes are doomed is…nothing. He doesn’t give any. He literally says in his interview that, “it should be obvious, if you can’t see it, you’re just blind I guess.” Slight paraphrase, but you get the gist. He backs that statement up by talking about how Discord screen share crashes a bunch on his Linux distro.

      Joined his Discord, saw a several people talking about how great Latin is and had a bunch of weird Roman empire theming, idk, just not great vibes.

        It’s not Unix-based either.

        https://en.m.wikipedia.org/wiki/SCO–Linux_disputes

        On August 10, 2007, a federal district court judge in SCO v. Novell ruled on summary judgment that Novell, not the SCO Group, was the rightful owner of the copyrights covering the Unix operating system. […] After the ruling, Novell announced they had no interest in suing people over Unix and stated “We don’t believe there is Unix in Linux”

        https://en.m.wikipedia.org/wiki/Linux

        Linux (/ˈlɪnʊks/ LIN-uuks)[11] is a family of open-source Unix-like operating systems based on the Linux kernel,[12] an operating system kernel first released on September 17, 1991, by Linus Torvalds.

          But on the same links you sent are saying:

          A Linux-based system is a modular Unix-like operating system, deriving much of its basic design from principles established in Unix during the 1970s and 1980s.

          What difference are between “*-based” and “*-like”? If the meaning are the same then I’m right, if Unix-based means must be like a fork directly from Unix and not just a copy build from 0, then yeah, you are right. And I think based and like are the same meaning.

          Edit:
          I also found this image: https://en.m.wikipedia.org/wiki/File:Unix_timeline.en.svg

          Unix timeline: Unix timeline where Linux is also present

          Edit 2:

          I just asked to ChatGPT and seems the AI can explain this:

          “Unix-like” and “Unix-based” are terms used in the realm of operating systems, particularly in relation to the Unix operating system and its derivatives. While they may seem similar, they convey slightly different concepts:

          Unix-like:
          - “Unix-like” refers to operating systems that resemble Unix in terms of design, behavior, or functionality, but may not necessarily be directly derived from the original Unix codebase.
          - These operating systems typically adhere to Unix-like principles and may incorporate similar features, commands, and programming interfaces.
          - Examples of Unix-like operating systems include Linux, FreeBSD, OpenBSD, and macOS (which is based on a Unix-like kernel called Darwin).

          Unix-based:
          - “Unix-based” specifically indicates operating systems that have a direct lineage or heritage tracing back to the original Unix operating system developed at Bell Labs in the 1970s.
          - These operating systems often have their roots in the Unix codebase, either through direct licensing agreements, re-implementations, or forks of the original Unix source code.
          - Examples of Unix-based operating systems include various commercial Unix variants such as Solaris, AIX, and HP-UX, which have historical ties to the original Unix.

          In essence, while both terms relate to systems that share similarities with Unix, “Unix-like” suggests a broader category of Unix-inspired operating systems, while “Unix-based” specifically denotes those with a direct lineage or relationship to the original Unix system.

          So you are right, and they probably wanted to mean Unix-like. But we could still say based as both has some kind of relationship, and that’s why Linux it’s on Unix timeline from wiki.

            So far my claims are:

            1. Linux is not Unix

            2. Linux is not “based” on Unix

            I’ve proven both claims using respected sources.

            From your reading, the missing clarification you are looking for is “POSIX”. Most people don’t know what POSIX is, that’s why it reads “Unix-Like” for general audiences. If Unix didn’t exist another synonym would supplement.

            Back to my original point – the OP, a layman, probably in good faith and though a honest misunderstanding, repeated a false claim that was resolved in a International 10+ year lawsuit in 2007.

            It’s literally mal-information. But hey in sure your elders think that a Xbox, PS5 and Computer are all “Nintendo’s or whatever”.

    Better sandboxing would be great. Wasn’t there a story earlier in the week that a missing environment variable in a desktop theme erased someone’s entire user directory? That shouldn’t really be possible.
