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.

Might be for time synchronization in order to not have to rely on a public NTP server.

What is the advantage of self hosting an NTP server?

After all, it just tells time

Knowing the time is pretty important to (networked) computers

One example:

Another use case: when you look at activities that flow across multiple devices and you're correlating the sequence of events, having every device set to the exact same, ideally correct time makes correlation of events less confusing.

It's for making your computers clocks be very, very close to each other. Not milliseconds close, but nano seconds. That is more important than one might think, especially for networks.

I'm going to have something similar at home at some point, just need to make a few more cable runs so one GPS can see the sky (= more accurate)
