  • This is the job for the OS.

    You can run most Linux systems with stupid amounts of swap and the only thing you’ll notice is that stuff starts slowing down.

    In my experience, only in extremely rare cases are you smarter than the OS, and in 25+ years of using Linux daily I’ve seen it exactly once, where oomkiller killed running mysqld processes, which would have been fine if the developer had used transactions. Suffice to say, they did not.

    I used a 1 minute cron job to reprioritize the process, problem “solved” … for a system that hadn’t been updated for 12 years but was still live while we documented what it was doing and what was required to upgrade it.











  • In my experience, the best way to get a cat to come to you is to completely ignore it. More often than not it will come to investigate.

    As best as I can tell, it’s simply impossible for a cat to imagine that you’re not aware of them, like they are hyper aware of you, and ignoring it signals that you don’t think that it’s a threat. Mutual slow blinking may or may not be involved.

    Note that I’m not a cat expert, haven’t lived with a cat since I was eight, but most cats seem to come over to say “Hi” when I’m visiting friends, to the point where owners seem to regularly exclaim that they’ve never seen their cat come over to a stranger.

    YMMV.







  • I joined Reddit because it was an open and moderated collection of communities … then after the blackout due to the API changes, moderators were sent packing and any sense of community that had been created was destroyed.

    I joined both Mastodon and Lemmy and I’m glad I did.

    The communities in both are nascent, but slowly growing, and that seems like a place I’d like to be.

    After Twitter became Xitter, I also joined Bluesky but that feels much more like people ranting and venting, less about making communities.
