  • tetha@feddit.detoLinux@lemmy.mlWhat exactly does systemd do?

    I mean to a certain degree, I can understand if people find a problem with Poetterings approach of doing things !CORRECTLY!. Like, systemd-resolved resolving A-records with multiple addresses ina deterministic fashion because it’s not defined not to be deterministic, and because actual load balancing would be better. It’s not wrong, but it’s breaking everything. And it got patched after some uproar. And there are a few things like that.

    But at the same time - I don’t think people appreciate how hard doing process management right on linux can be, especially if the daemon to run is shitty. Like, init scripts just triggering the shutdown port on a tomcat - except the tomcat is stuck and not reacting to the normal shutdown port and now you have a zombie process and an init script in a fucked up state. Or, just killing the main process and for some reason not really removing the children, now there’s zombies all over the place. Or, not trying appropriate shutdown procedures first and just killing things, “because it’s easier” - except my day just got harder with a corrupt dataset. Or, just trying soft and “Pwease wexit Mr Pwocess” signals and then just giving up. Or having “start” just crash because there was a stale PID from an OOM killed process around. Man I’m getting anxiety just thinking about this.

    And that’s just talking about ExecStart and ExecStop, pretty much, which I have done somewhat correct in a few init scripts back in the day (over months of iteration of edge cases). Now start thinking about the security features systemd-analyze can tell you about, like namespaces, unmapping syscalls, masking parts of the filesystem, … imagine doing that with the jankyness of the average init.d script. At that point I’d start thinking about rebooting systems instead of trying to restart services, honestly.

    And similarly, I’m growing fond of things like systemd-networkd, systemd-timesyncd. I’ve had to try to manage NetworkManager automatically and jeez… Or just directly handling networking with network-scripts. Always a pleasure. Chucking a bunch of pretty readable ini-files into /etc/systemd/networkd is a blessing. They are even readable even to people rather faint on the networking heart.

    And even password based disk encryption can be defeated with 2-3 physical accesses if an organization wants to hard enough. Keyloggers can be very, very sneaky.

    At that point you’d have to roll something like Yubikey-based disk encryption to be safe, because this re-establishes control over some physical parts of the system. Until they find the backup Yubikey you had to not lose all data by losing the primary key you’re carrying around to maintain control over it.

    It’s not a battle the defending side can win.


  • Catan just feels weird. The thing is - and I kinda validated that recently by watching highlevel competetive play of the catan base game, but: You only have like 2-4 meaningful decisions in a game. The rest is just follow through and dice.

    And these things aren’t that hard to see at a decent level. And when you make these decent decisions, you mostly just win. Even with the robber, there’s limited counterplay to these good initial choices. This makes it hard to play casually as well once you know the good things.


  • I’m more of a specialist and a rule lawyer.

    I mostly have a small collection of games ranging from easily explained to really huge. Like, I have Flashpoint, or Pandemic, or Betrayal at the house on the Hill. All of these are games you can understand well enough in 1-2 rounds of going if you know boardgames a bit. And then there are things like Junta, Arkham Horror, Eldricht Horror, Battlestar Galactica, considering to get the new dune game. Those are great, but a lot harder to get into.

    But that’s a quality my current gaming circle likes. I can pick up a lot of rulesets and digest them decently quickly, because I’ve played a lot of games, and a lot of complicated games over the years. Like, if you’ve dealt with MtG and Dominion, you’ve seen 90% of deck building concepts and rules. Some P&P RPG experiences in 2-3 frameworks cover a lot of ground for a bunch of game rules. You kinda learn how rules tend to be written, how rules tend to be designed, and how rules are usually intended to be and that helps processing rulesets quicker.
