Pump.io is a "social server with an ActivityStreams API". It’s from the same people that originally created StatusNet, which has now become GNU social. Pump.io servers are nodes in a federated social network: when you have an account on one, you can interact with others on that server, but also others with accounts on other pump.io servers. It’s free software, so you can host your own instance and connect to others, wherever their servers may be.

Not everyone uses the Raspberry Pi while it’s hooked up to a monitor like a normal PC. Due to its size and portability, it can be located almost anywhere that it can be powered and it’s widely used as a file server, media centre and for other nontraditional applications. Some of these uses won’t easily allow access to a monitor for easy updates and maintenance. While you can always SSH in, it’s a bit slower than a full web interface that allows for custom commands and a view of the Pi’s performance. We’re using software called RaspCTL, which is still in development, but works just fine for now.
