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.

I kind of want to self host a lemmy instance. What are the requirements for a single user lemmy instance?

I did this for a while. However, after subscribing to several groups, there was constant disk activity and it ate network bandwidth. After two months I’ve stopped my server and went back to using a public instance.

How intensive was it exactly?

I didn’t notice any big drops in network or CPU performance. Usually, because other network traffic had priority. But my server’s HDD constantly rattling along got me thinking that it wasn’t worth it. There are several other containers running on that box and I don’t have that much HDD activity with them.

There are postgres settings to reduce disk writes. There's a max size and a timeout to write to disk. By default these values are on the lower end I believe.

Yeah, but I didn’t want to fiddle with some custom settings. The same official postgres container works great with other apps.

Yeah works good until its under load which federation does have. Matrix and Lemmy both got like 20GB of RAM dedicated to the database on my servers.
