Haven't seen a thread on this before so I'll start one. The Raspberry Pi 2 is really a marvel. For $30 you get a 90MHz quad-core processor and 1GB RAM on a Linux platform. The platform also comes standard with an ethernet connector, 4 USB ports, HDMI, and a micro SD slot. I picked up my first one today with a 32GB memory card. I intend to install a Tomcat Server and a database as support to the D3.js data visualizations that I've been working with lately. I'll post occasional updates as I go along. Feel free to jump in with your projects or ideas. Let the games begin! First step is to install the OS. This is a good video.
