Thus far, a few tools have been brought to bear.

My primary computer is a 2.66 GHz Core2 Duo desktop with 6 GB of RAM I built my freshman year.  It runs Server 2008 R2, available free to students from Microsoft Dreamspark for scholarly purposes such as these.

This machine hosts a CentOS virtual machine running on VirtualBox by the now-defunct Sun Microsystems. CentOS in turn hosts this website, Eclipse, and the Android SDK.

The setup sits behind an old Pentium III box running IPCop, a simple Linux-based firewall.
