StuxNet Was American-Made Cyberwarfare Tool (NY Times) — not even the air gap worked for Iran, “It turns out there is always an idiot around who doesn’t think much about the thumb drive in their hand.”
So Much For The Paperless Society (Beta Knowledge Tumblr) — graph of the waxing and waning use of bond paper in North America. Spoiler: we’re still using a lot.
Magnifying Temporal Variation in Video — 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. This is amazing: track the pulse in your face from a few frames. (via Hacker News)
