As I said in my recent review, I generally had a blast making my way through Uncharted: Golden Abyss on the PlayStation Vita. Despite some annoyances with the system's touch-screen and tilt-based controls, I had a good time working through the shooting and climbing sections and being rewarded with some well-acted witty banter in the cut scenes. But despite my overall enjoyment, there was still one point in the game where I was so frustrated I was ready to turn it off and never return. And while this frustration was probably at least as much my fault as the game's, I still think it would have been nice, and much less frustrating, if the game had offered just a little help getting me past that point.

Facebook's pending initial public offering gives credence to the argument that personal data is the oil of the digital age. The company was built on a formula common to the technology industry: offer people a service, collect information about them as they use that service and use that information to sell advertising.

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.

"Salman Khan's dream college looks very different from the typical four-year institution. The founder of Khan Academy, a popular site that offers free online video lectures about a variety of subjects, lays out his thoughts on the future of education in his book, The One World School House: Education Reimagined, released last month. Though most of the work describes Mr. Khan's experiences with Khan Academy and his suggestions for changing elementary- and secondary-school systems, he does devote a few chapters to higher education."

As a child I used to read my grandfather's Popular Science and Popular Mechanics magazines. The constant promise and inevitable disappointment of amazing technologies that mostly never materialized (a problem likely exacerbated by my focus on the amazing and outlandish ones) made me skeptical of futurist predictions. It is somewhat strange then, that I now commonly find myself a proponent of futurist visions equally as grand as those that once made me a cynic. But I'm not alone in seeing the near future as a quickly changing technological landscape. In their recent book Race Against The Machine: How the Digital Revolution is Accelerating Innovation, Driving Productivity, and Irreversibly Transforming Employment and the Economy, MIT's Erik Brynjolfsson and Andrew McAfee* offer a similarly sweeping view of how technology is, and will be, shaping our future

SANTA BARBARA-"Maybe we're just too dumb," Nobel laureate physicist David Gross mused in a lecture at Caltech two weeks ago. When someone of his level wonders whether the unification of physics will always be beyond mortal minds, it gets you worried. Since his lecture, I've been learning about a theory that seems to confirm Gross's worry. It is so ridiculously hard that it could be the subject of an Onion parody. But at the same time, I've been watching how physicists are trying to power through their intimidation, because the theory promises a new way of understanding what space and time really are, at a deep level.

Scaling College Composition by AUDREY WATTERS on 22 APR, 2012 I've been thinking a lot this week about two seemingly unrelated news items. The first, the research by David Shermis and Ben Hamner that found that automated essay grading software performs comparably to human graders. (See the Inside Higher Ed story.) The second, the official unveiling of Coursera, the latest online learning startup to spin out of Stanford, that promises to offer a full course catalog, including many classes in the humanities. (Here's my write-up of the news). The connection: scaling how we assess student writing.

Medical researchers around the world will from Friday have access to information on half a million Britons, with the release of the globe's largest collection of human health data.

Certain About Nothing In "US Corporates Shy to Offer Guidance," the Financial Times reports that those who are at the economy's front lines have a less than clear vision of where things are headed:

A few months back, we talked about the challenges faced by libraries in the era of ebooks, digital information and shrinking budgets. An emerging idea, now being pioneered at one New York state library, is to offer 3D printing facilities to enable constituents to develop and innovate new ideas and products. The Fayetteville Free Library of Fayetteville, NY recently has assumed a new mission in efforts to serve its constituencies with 3D printing facilities. The "FFL Fab Lab" is a space set aside with 3D printing technology, which seeks to encourage innovation and learning of the concept. At the foundation of the FFL's Fab Lab will be a MakerBot Thing-o-Matic 3D printer, donated to the library. The Fab Lab's 3D printer uses plastic as its raw material.

Let's say you have two hosts, somewhere out on the Internet: Maybe dedicated servers, maybe Amazon EC2 or Rackspace instances, maybe a mix of the above. Now assume it's your job to provide secure, encrypted connectivity between two services running on those hosts. If those services do not use an encrypted protocol by themselves - such as non-SSL capable SMTP mail servers - then the standard answer has always been: "Use stunnel or OpenVPN!". While both of those are good, cross-platform solutions which can forward unsecure traffic over an encrypted tunnel, I believe that they come not only with administrative overhead, but also introduce a significant performance hit. I believe that there are now solutions that are easier to use, more flexible and most importantly, deliver much better performance. In this article, I will compare stunnel performance  characteristics with vCider's virtual private network solution (sign up for use with up to 8 nodes is free). You will see that vCider not only offers more flexibility and is easier to use, but also provides significantly better network performance and reduced CPU load. For my test, I have created two Ubuntu instances on Rackspace. Please note that both stunnel as well as vCider can work across network and cloud provider boundaries.

"Are more people doing wrong or are more people speaking up? Retractions of scientific papers have increased about tenfold during the past decade, with many studies crumbling in cases of high-profile research misconduct that ranges from plagiarism to image manipulation to outright data fabrication. When worries about somebody's work reach a critical point, it falls to a peer, supervisor, junior partner or uninvolved bystander to decide whether to keep mum or step up and blow the whistle. Doing the latter comes at significant risk, and the path is rarely simple. Some make their case and move on; others never give up. And in what seems to be a growing trend, anonymous watchdogs are airing their concerns through e-mail and public forums. Here, Nature profiles three markedly different stories of individuals who acted on their suspicions. Successful or otherwise, each case offers lessons for would-be tipsters."

"Academia.edu, a social network for scholars, is unveiling a new feature today that its founder Richard Price hopes will help address part of the "credit gap" for research. Academia.edu allows users to upload and share their research papers, and the site is launching its Analytics Dashboard for Scientists today that Price says will let scholars see the "real-time impact" of their work. Academic publishing has long been a black-box in terms of both who's reading and who's citing. Publishing in journals may be expected (required, even), but the delays in the publishing process can make it challenging to ascertain how much influence work has. "It typically takes about 3 to 5 years for citations to actually appear back in the process," argues Price, pointing to the lengthy time between researching, writing, peer-reviewing, and publishing."
