  • It had two buildings. Is that difficult to understand or what? Historically they were separate schools built close together. (Probably a boys and girls school but I don’t remember)

    Each had a main part that was a single corridor on 4 floors with classrooms off it. There were extra bits that weren’t part of the main corridor, too, which weren’t as tall, and the main part also wasn’t all classrooms; in one building the bottom floor was, I think, just toilets and changing rooms, then admin offices, and only then were there classrooms, but I can’t remember for sure. In the other building there were 3 complete floors of classrooms and I think one half floor, with the rest of the bottommost floor occupied by a gym.

















  • An overarching principle of security is that of minimum privilege: everything (every process, every person) should have the minimum privileges it needs to do what it does, and where possible, that privilege should be explicitly granted temporarily and then dropped.

    This means that any issue: a security breach or a mistake can’t access or break anything except whatever the component or person who had the issue could access or break, and that that access is minimal.

    Suppose that you hit a page which exploits the https://www.hkcert.org/security-bulletin/mozilla-firefox-remote-code-execution-vulnerability_20230913 vulnerability in Firefox, or one like it, allowing remote code execution. If Firefox is running as root, the remote attacker now completely controls that machine. If you have SSH keys to other servers on there, they are all compromised. Your personal data could be encrypted for ransom. Anything that server manages, such as a TV or smart home equipment, could be manipulated arbitrarily, and possibly destroyed.

    The same is true for any piece of software you use, because this is a general principle. Most distributions I believe don’t let you ssh in as root for that reason.

    In short: don’t log in to anything as root; log in as a regular user and use sudo to temporarily perform administrator actions.

    P.S. your description of the situation shows you don’t know the nature of vulnerabilities and security - if you’re running servers then this is something you should learn more about in short order.


  • If you federate with something too massive though it has undue weight on the entire system. It is likely to be Embrace, Extend, Extinguish again, and it’s reasonable to want to avoid that.

    For people who don’t remember, the pattern would be something like:

    1. Federate and use the existing ecosystem to help you grow and to grow mutually (Embrace)
    2. Add new features that only work locally, drawing users away from other instances to your own (Extend)
    3. Defederate - the remainder is left with a fraction of the users since many moved away, so the users on the local instance don’t care. (Extinguish)

    It depends whether 2 actually succeeds at pulling users in. Arguably most people already on the Fediverse are unlikely to jump ship to Facebook, but you have to consider what happens in a few years if it’s grown, but Facebook is a huge name which makes people less likely to join other instances.
