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.

Looking at my sql databases, I noticed there’s other identifiers on users and content. Not the url.

It may be that the url is linked to the ID. And that ID can just change.

I’m pretty much a noob. Just a lurker on the matrix chats.

I'm talking purely from an ActivityPub/Activity Streams/Activity Vocabulary/JSON-LD perspective. There are some other local identifiers for things in Lemmy, but those do not matter for the purposes of federation. Any Object that is federated is expected to have an ID that is a URL at which you can make a GET request with the proper Accept header and you will get the latest version of that Object. AFAIK there is no provision for IDs to change.

Understood. I don’t know how the devs intend to overcome that challenge. If if it’s even a realistic goal. I just know it gets discussed often.
