Where the Internet Lives: The First-Ever Glimpse Inside Google’s Data Centers. So it really is a series of tubes.
For the first time ever Google has posted dozens of rare photographs inside and around its data centers revealing the absurd level of organization, energy and design that goes into powering some of the largest, most powerful systems plugged into the internet. My absolute favorite aspect is the color-coordinated design of their infrastructure as it correlates to the Google logo. What wonderful attention to detail. See many more photos of their eight data centers and Street View imagery of their Lenoir, NC data center at Where the Internet Lives. All photos by Connie Zhou.
Computer Science Unplugged. This activity uses Unplugged-style activities to introduce the idea of database queries, and leads to "plugged-in" experiences as follow-up.
It has been contributed by Mark Dorling, Digital Schoolhouse, in the UK. From the abstract: This report gives details of a series of computing lessons designed to relate fundamental concepts of database use and design to children in Primary and Secondary Education (ages of 6 to 16). The skills and concepts developed in these les- sons begin at a very simple level but progress to cover abstract concepts such as Relational Databases. The series has been aligned to match the scope, range and targets recommended in the Computing At Schools document A Curriculum for Computing.
