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.

A huge problem are developers who lack a fundamental understanding of how the internet even works. I've had to explain how short, unqualified names resolve vs how fqdns resolve. Or why even you may not be able to reach another node in your proverbial cluster, because they are on different subnets. Or, why using GUIDs as hostnames is a generally bad idea, and will cause things to fail in unpredictable ways, especially with deeply nested subdomains.

GUIDs?
Could you expand on that topic? :)

Why would someone want that as their hostname???
I'd understand mountpoint but that?
