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.

"Businesses invest billions of dollars annually in market research studies developing and testing new ideas by asking consumers questions they simply can't answer. Asking consumers what they want, or why they do what they do, is like asking the political affiliation of a tuna fish sandwich. That's because neuroscience is now telling us that consumers, i.e., humans, make the vast majority of their decisions unconsciously. Steve Jobs didn't believe in market research. When a reporter once asked him how much research he conducted to develop the iPad, he quipped, "None. It isn't the consumers' job to know what they want." And according to some measures, the iPad became the most successful consumer product launch ever and Apple went on to become the most valuable company of all-time."

There's a new adventure video capture company in town, and both Zeyez and GoPro would have good reason to be afraid. You may not have heard of Pivothead -- the company has had a remarkably quiet push to market over the last few months -- but the video recording eyewear startup could very well become a household name after its first products hit the market this April for $349. Aurora, Durango, Moab and Recon may offer distinct exterior designs, but they're virtually identical under the hood. Each model includes an eight-megapixel Sony sensor (that reportedly captures higher quality images than the iPhone 4S cam), a four-element glass lens, 8GB of built-in storage, a 440mAh battery (with about an hour of shooting time) and three video modes: 1080/30p, 720/60p and 720/30p. We had a chance to go hands-on with Pivothead earlier today, and took the glasses for a spin on the streets of New York City. You'll find that sample video, along with our impressions, just past the break.

"Before I became a university professor, I had a long career in the entertainment business-first as a concert producer for the likes of Bob Dylan and The Band, and later as producer of motion pictures, including Martin Scorsese's Mean Streets and The Last Waltz. Both the music and movie industries have been utterly transformed by the Internet, in positive and negative ways. But I sense that we're still at the beginning stages of this big shift, and that some of the most interesting developments are yet to come. For example, social sentiment analysis is going to change the game for Hollywood marketing."

Android applications downloaded by as many as 185 million users can expose end users' online banking and social networking credentials, e-mail and instant-messaging contents because the programs use inadequate encryption protections, computer scientists have found. The researchers identified 41 applications in Google's Play Market that leaked sensitive data as it traveled between handsets running the Ice Cream Sandwich version of Android and webservers for banks and other online services. By connecting the devices to a local area network that used a variety of well-known exploits, some of them available online, the scientists were able to defeat the secure sockets layer and transport layer security protocols implemented by the apps. Their research paper didn't identify the programs, except to say they have been downloaded from 39.5 million and 185 million times, based on Google statistics.

Note-I am going to try this for our blog. If you've ever wondered how some website that looks like it was an early draft from the proverbial infinite number of monkeys on infinite keyboards managed to get to the top of a search result page instead of something you actually want to read (or something you've written), you've been victimized by the dark art of search engine optimization (SEO). In the never-ending battle for the top of the Google search results page, and for advertising click-throughs, marketers and bloggers enlist an ever-changing bag of tricks to game search engine algorithms, often with the help of SEO consultants and a collection of tools that track the best tactics of the moment.

It is rather odd how often I hear the expression paradigm shift during contemporary scientific presentations and seminars. The expression was popularized by Thomas Kuhn's book The Structure of Scientific Revolutions. In that book, Kuhn referred to ground-breaking and revolutionary changes in scientific thought as paradigm shifts, but the expression is so over-used today that even minor discoveries are sometimes marketed as paradigm shifts.

There's no doubting the cloud invasion. But the research firm Gartner believes the personal cloud will replace the PC as the center of our digital lives sooner than you might think: 2014. "Major trends in client computing have shifted the market away from a focus on personal computers to a broader device perspective that includes smartphones, tablets and other consumer devices," Steve Kleynhans, research vice president at Gartner, said in a statement on Monday. "Emerging cloud services will become the glue that connects the web of devices that users choose to access during the different aspects of their daily life."

London, UK, June 16 and 17: Open IoT Assembly: "In 2011 Pachube published this attempt at a Bill of Rights for the Internet of Things. Data ownership will continue to be one of the defining issues of this decade. As the Internet of Things matures, clear lines will be drawn as companies bring products and services to market. Business models will be built on one of two philosophies:       *    Controlling a customer's access to their data and limiting its use to a single service. Profiting through vendor lock-in and switching costs/hassle.     *    Maximizing the value that is built on top of data and constantly innovating. Building a product that customers choose based on its own merits.

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.

When the founders of GitHub moved into their swank South-of-Market loft last year, the first thing they did was redecorate. They turned the floor's biggest office into a parody of an executive suite - complete with fake fireplace, plush leather chairs, and a wooden globe that slides open to reveal a bottle of single malt scotch. Hanging from the wall is a painting of a cat, dressed as Napoleon, with five octopus-like legs. They call it the Octocat.

Andrew Pole had just started working as a statistician for Target in 2002, when two colleagues from the marketing department stopped by his desk to ask an odd question: "If we wanted to figure out if a customer is pregnant, even if she didn't want us to know, can you do that?

"The world is anxiously awaiting Cotton Candy's release," said Borgar Ljosland, CEO and founder of FXI. "We've had interest in the any screen computer for everything from portable set top box gaming and entertainment to mobile any screen computing, in addition to a host of specialized medical, automotive and other applications. The size, raw horsepower and combined HDMI, USB and MicroUSB connectivity bring unprecedented flexibility to the portable market.

Gamers angered at the "bleak" ending of Mass Effect 3 have campaigned for an alternate conclusion - and raised more than $70,000 (£44,000) for charity.
