31st March: World Backup Day 2013


World Backup Day is a day for people to learn about the increasing role of data in our lives and the importance of regular backups.

This independent initiative to raise awareness about backups and data preservation started out — like most good things on the internet – on reddit by a couple of concerned users. Let’s make this happen!

This tool provides information about traffic to our services around the world. Each graph shows historic traffic patterns for a given geographical region and service. You may select a region and then choose a service to view each respective graph. Graphs are updated as data is collected, normalised and scaled. By showing outages, this tool visualises disruptions in the free flow of information, whether it’s a government blocking information or a cable being cut.

Eulerian Video Magnification for Revealing Suble Changes in the World

Our goal is to reveal temporal variations in videos that are difficult     or impossible to see with the naked eye and display them in     an indicative manner. Our method, which we call Eulerian Video     Magnification, takes a standard video sequence as input, and applies     spatial decomposition, followed by temporal filtering to the     frames. The resulting signal is then amplified to reveal hidden information.     Using our method, we are able to visualize the flow     of blood as it fills the face and also to amplify and reveal small     motions. Our technique can run in real time to show phenomena   occurring at temporal frequencies selected by the user.
