Welcome! This website is hosted on my home server, a Raspberry Pi 2 Model B. It is running Raspbian Jessie Lite, a version of Debian. You can see this machine in the photo below, just one power connector and an ethernet port, in a Pi-Blox case.
There are a few things running on this machine, such as an eggdrop IRC bot, which can be seen in our IRC channel by typing !commands. The bot uses TCL to gather data from the shoutcast servers XML stats every 30 seconds. Statistics such as listeners and whats currently playing can then be shown in IRC when a user says a trigger such as !info in the channel. I also run a personal IRC bouncer using sbnc on the machine, a secondary DNS server for my websites and a few other services.
It is connected to a 76Mb↓ 19.5Mb↑ fibre internet connection.
Its quite amazing what you can do with the little Raspberry Pi as a server and it uses less power than my router!
