  • rspamd is used nowadays. Add sieve filtering to automatically move mails with a 7.0 or higher to a spam-folder. Manually move mails there that haven’t been detected and move mails out of the spam folder that have been falsely detected (personally don’t have any false positives with rspamd).

    Then set up bayes learning with rspamd, either when mails are moved between folders or every few hours.






  • Honestly, that’s what most web API’s are. You are just pushing data around. The “hard” part is that everyone has their own opinions on how it should be formatted.

    And of course the minor inconvenience of having to give the user a way to make data entry easy, convenient and consistent.

    But deep down it’s all spreadsheets. The faster you can wrap your head around that the easier programming is for you.



  • I’ve got a really obscure one.

    Anyone here heard about FLI4L? Floppy ISDN for Linux? Built from the ground up to be usable on your really old PC as a router. Originally it fit on a single floppy disc and was able to turn a 386 into a modem or ISDN router. Later they added the ability to route between LANs and DSL.

    By now the requirements have been raised to super beefy 586 PCs. It probably doesn’t fit on a floppy disc anymore.






  • I was and still am on HDD. The CPU was upgraded as well. I migrated to a new server.

    The main culprit was the database. As far as I’m aware Lemmy is missing some indexes and due to the ORM they used didn’t always have optimised queries. Now with 64 GB RAM the whole database (almost 30 GB) fits in there fixing most of those issues.

    The real fix will probably come with Lemmy 1.0. They radically changed the database layout and queries.

    Image proxying wasn’t bad for performance. Just storage space. It was growing really really fast. Now that only I am using it to host the pictures I uploaded it is still much too large (24 GB). But its directory structure is so convoluted that I can’t really debug it. My stuff really shouldn’t be taking up more than a few hundred MBs.

    I am the only one using this instance. I am subscribed to a hundred communities or so. I am always pretty up to date with my Lemmy versions.





  • I run an instance just for myself and it was a nightmare on HDD and 16 GB RAM. It was slow as molasses. Supposedly the database layout will be fixed with the 1.0 release that is just around the corner.

    Since I upgraded to 64 GB it’s been pretty smooth. Still wild that that is necessary for a single user.

    Also, disable image proxying. I have no idea what pict-rs does but it seems to be too much.

    You should consider running Piefed instead. It’s not as resource hungry as Lemmy.
