Just a small niche in the web


There is not much that you'll find here on this server. It is mostly used for the families Friendica node and the personal cloud.

Friendica Node

Friendica is a social communication server that enables you to host your own social-media node. We use it at social.diekershoff.de. Friendica uses the ActivityPub, Diaspora* and OStatus protocols, thus enables you to communicate with a wide range of decentraliced platforms, weaving together a decentralised social-network—the Fediverse—with approx  four  ten million users (source the-federation.info).

You can find my account at tobias(at)social.diekershoff.de.


This niche started out as an experiment on what resources Friendica would need to be run. At that time it was a Raspberry Pi 2B, nowadays it is a RPi 4B.

  • RaspBerry Pi 4B / 8GB RAM
    After five years on a RPi2B it turned out, that the database size had grown so that it did not fit anymore into the 1GB RAM of the older model.
  • Stock Rasbian
    boot from SD, all the system lives on an external USB HDD
  • lighttpd, PHP, MariaDB
