The centenary of Alan Turing's birth is being greeted by an extraordinary response, not only in mathematical and scientific circles but in a much wider public arena. It marks the awareness that he was one of the 20th century's seminal figures, whose brief life is better appreciated in the 21st century than in his own.

Salman Khan's simply narrated, faceless home videos on everything from algebra to French history have been viewed half a billion times. Last year, a number of schools began "flipping" their classrooms, having students study Khan videos by night and do homework with teachers by day. His staff has been ramped up to 32, including the recent high-profile addition of Google's first hired employee, programming ace Craig Silverstein. The staff's immediate mission is to further broaden the site's content and improve assessment and feedback features so the Khan Academy experience becomes more interactive.

I went to the GLUE conference to get in over my head. That was my entire goal. I wanted to learn about the technology that helps to stitch together the various parts of the Internet, but I also wanted to spend some time getting to know the people who made that technology do what it does. Over the course of 2 days I met people who made me feel dumb, saw thousands of lines of code and left with a new appreciation for how technology works.

Robert Harvey asks: Occasionally I see questions about edge cases on Stack Overflow that are easily answered by the likes of Jon Skeet or Eric Lippert-experts who demonstrate a deep knowledge of a particular language and its many intricacies. Here's an example of this from Lippert's MSDN blog: You might think that in order to use a foreach loop, the collection you are iterating over must implement IEnumerable or IEnumerable. But as it turns out, that is not actually a requirement. What is required is that the type of the collection must have a public method called GetEnumerator, and that must return some type that has a public property getter called Current and a public method MoveNext that returns a bool. If the compiler can determine that all of those requirements are met then the code is generated to use those methods. Only if those requirements are not met do we check to see if the object implements IEnumerable or IEnumerable. This is cool stuff to know. I can understand why Eric knows this; he's on the compiler team, so it's explicitly in his job description to know. But how do mere mortals, those of us on the outside, find out about stuff like this?

A refrain running through the debate over global warming suggests we need to nothing to slow it, because after all, the climate science predicting more warming could turn out to be wrong. Giordano Bruno was burned at the stake, and Galileo almost was, for objecting to the scientific doctrine that the Sun revolves around the Earth. For two thousand years people believed in systems of physics and astronomy that turned out to be incorrect. And for a few more centuries after that they held to a new celestial mechanics only to see it displaced by relativity theory.

Sergei Skorobogatov, a postdoc in the Security Group at the Computer Laboratory of the University of Cambridge has written up claims that reprogammable microchips from China contained secret back-doors that can be used to covertly insert code:

It was a scene as creepy as a Hannibal Lecter movie. One man was shot to death by Miami police, and another man is fighting for his life after he was attacked, and his face allegedly half eaten, by a naked man on the MacArthur Causeway off ramp Saturday, police said.

A report in the New Journal of Physics shows how the quest for an invisibility cloak is leading to cleverer ways to use and manipulate light. The trick could aid the analysis of complex samples or even communications.

The eminent British scientist James Lovelock, back in the 1970s, formulated his theory of Gaia, which held that the Earth was a kind of super organism. It had a self-regulating quality that would keep everything within that narrow band that made life possible. If things got too warm or too cold-if sunlight varied, or volcanoes caused a fall in temperatures, and so forth-Gaia would eventually compensate. This was a comforting notion. It was also wrong, as Lovelock himself later concluded. "I have to tell you, as members of the Earth's family and an intimate part of it, that you and especially civilization are in grave danger," he wrote in the Independent in 2006.

Results from FIA Aalborg: The Internet of Things (IoT) is one of the most important fundaments for the smart cities, and is becoming slowly but steadily one of the core elements of the Future Internet (FI). In fact, various architectures and approaches from Future Internet such as Cloud Computing (Software as a Service - SaaS), which are being linked with the Web of Things, which is also allowing to define Sensors as a Service (SaaS) are clear examples of this relation between Future Internet and IoT architectures. At this particular point, where the IoT is a reality, where several IoT-based high scale deployments are being carried out such as Rome, and Santander. It is essential to discuss what are the IoT-specific aspects that the FI architecture has to take into account, in order to efficiently map the IoT architectures into an overall FI architecture, and particularly, how to manage rights of the individual (i.e. privacy) and its interaction with IoT objects taking into account aspects like delegation, access control as key aspects in the inclusion of the Internet of Things in the common lives with its total inclusion in the city of the future.

As a serial entrepreneur and dotcom millionaire, Neil Patel can afford to be picky about his choice of luxury residence. But instead of a country mansion, penthouse apartment or gated community in the suburbs, the founder of internet start-ups KISSmetrics and Crazy Egg has set up home in a location he says best suits his hectic work schedule -- the Hyatt Hotel in downtown Seattle. "I bought a place in a hotel because its convenient for me," says the 27-year-old, who often finds himself working more than 70 hours a week.

In 1991, when I was a staff writer for Scientific American, I wrote a letter to Thomas Kuhn, then at MIT. I said I wanted to profile him for Scientific American and "tell readers how you developed your views of the process of science." When he didn't respond, I called. Kuhn was reluctant to do the interview. He distrusted journalists, and he was still peeved by an old Scientific American review of his 1962 book The Structure of Scientific Revolutions. When I persisted, Kuhn asked to see other profiles I had done, and I mailed him pieces on his MIT colleagues Claude Shannon and Noam Chomsky.

ArduGate: a web gateway for Arduino that makes possible to use JavaScript inside the web browser to interact with Arduino. Currently available just for Windows,  however, release for Linux and MAC OS X will be available soon.

Although there is an urban legend that the world will end this year based on a misinterpretation of the Mayan calendar, some researchers think a 40-year-old computer program that predicts a collapse of socioeconomic order and massive drop in human population in this century may be on target

The sustainability crisis has provoked an unexpected and dramatic response from academia. Until now, higher education institutions have tended to focus on sustainability within their own borders. This has predominantly been via sustainability education, research and designing green or carbon neutral campuses.

Are the financial markets rational?  It's a tough claim to make as share prices and bond yields zoom up and down during a single day, hour, or even second, sometimes without any obvious reasons.  Yet for the first time in human history, the markets may be approaching the ideal of rationality that economists have long cherished.

Say goodbye to your mouse and keyboard. Leap represents an entirely new way to interact with your computers. It's more accurate than a mouse, as reliable as a keyboard and more sensitive than a touchscreen.  For the first time, you can control a computer in three dimensions with your natural hand and finger movements. This isn't a game system that roughly maps your hand movements.  The Leap technology is 200 times more accurate than anything else on the market - at any price point. Just about the size of a flash drive, the Leap can distinguish your individual fingers and track your movements down to a 1/100th of a millimeter. This is like day one of the mouse.  Except, no one needs an instruction manual for their hands.

If the Space Race characterized the twentieth century, it's possible the Teleportation Race may characterize the twenty-first. Scientists all over the world are trying to perfect teleportation techniques, for a wide variety of applications including communications technology. (Sorry, this isn't the kind of teleportation that involves sending you through a wormhole to the other side of the galaxy.) And now, a group of researchers led by Juan Yin at the University of Science and Technology of China in Shanghai have published a paper on ArXiv describing how they teleported entangled photons over a distance of 97 kilometres across a lake in China.
