Selfhosted

A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

Hot on the heels of LCS (https://lemmy.world/post/557346), I bring you Lemmy Post Purger (LPP).

Instances can grow fast, and that can be a problem if you have limited disk space. If you don't mind losing history that your users have not interacted with, LPP can help. It will purge posts along with their comments and media before a certain time period if no comments, likes, or saves exist for users on your instance.

I feel like this ruins the aspect of an archive of information where users can go back through and find useful info similar to SO in a way. Maybe there will be a meta search engine for looking through all of the popular instances?

Generally I agree. But I think there are divergent interests:

  1. Sustainable decentralisation
  2. Archiving as much useful information as possible behind a good global search

At some point these conflict and it makes sense to direct efforts specifically toward one if you want it realised.

Purging to lower costs makes sense for decentralisation.

To have a great archive of human knowledge, at some point it would make sense to have instances or services dedicated to that.

We need a sort of Pushshift for Lemmy. That way Lemmy instances can purge posts for their own survival, while a full archive exists and can be accessed if needed. Best of both worlds. Perhaps the Lemmy project should be working with the Pushshift people to integrate that functionality.

I think it depends on the implementation of this idea, given the nature of federation. It seems like a good place to start.

It's a balance between losing information due to purging old stuff, and losing information due to an instance shutting down entirely from costs being too high.
