This WordPress 3.6 site is served from an Ubuntu 12.04.1 host running on Amazon’s EC2 service.
The theme is “Twenty Thirteen”, utilizing the “Intuitive Custom Post Order” plugin.
The header image is cropped from the below photo I took while touring the Georgetown Steam Plant. I selected this photo as it demonstrates the value of using simple status indicators even in giant, complex systems (like a steam plant).
