  • Why would you reserve ram for swap???

    You’re hindering the OS’s ability to manage memory.

    Put swap on disk. Aim for it to rarely be touched - but it needs to be there so the OS can move idle memory data out if it wants to.

    Don’t hard-allocate a memory partition for postgres. Let it allocate and free as it sees fit.

    Then the OS will naturally use all possible RAM for cache, with the freedom to use more or less for the server process as demand requires.

    Monitor queries to ensure you’re not seeing table scans due to missing indexes. Make sure VACUUM is happening either automatically or manually.














  • I got news for you:

    • X11 has seen many extensions, competing standards, fragmented implementations, ambiguous “best choices” for users, etc.

    • MacOS and Windows have seen many API changes, deprecations, even wholesale language and architecture swaps.

    • X11 is a 40 year old architecture that is far from optimal.

    • The people doing the work set the standard in the Free Software world. They stopped working on XFree86.

    • Part of the friction getting linux on the desktop is due to X11.

    • You can still run twm and X. No one is stopping you.






  • Lemmy.ml seems to have a clone of most of the “top reddits”, somehow the most subscribed communities out there, and all dominated by one or two posters who post pro-China/pro-DPRK/anti-Western content all day long.

    It definitely is going to confuse newcomers and make a bad first impression. I wonder if they auto subscribe people to those so their propaganda ends up at the top of the communities list.

    Part of the solution is to better inform new users the part of the community name is the host, just like Main St in one city is different from Main St in another city. You choose the city you want to live in first.

    But, it may also be interesting to have the ability for admins to selectively merge like-named communities with other agreeable instance admins, and count subscribers to both as one group.
