Hallo and welcome to this little node in the interwebs. Its main purpose is to test how well the Raspberry Pi 2 performs as server for a Friendica node, so don't expect to find much more here, except maybe a log of the performance and some notes about the setup.
You can find much more content, e.g. my blog, at diekershoff.net. With the move of the server to the RasPi the very old content (e.g. my old blog) vanished... sorry for that.
