writes with this excerpt from an IDG story about the creation of an Android fork
made just for Google's modular cell-phone project
: A special edition of Android had to be created for the unique customizable design of Project Ara, said George Grey, CEO of Linaro. ... Android can already plug and play SD cards. But Grey said additional OS functionality is needed for storage, cameras and other modules that are typically inside smartphones, but can now be externally added to Project Ara. A lot of work is also being done on UniPro transport drivers, which connect modules and components in Project Ara. UniPro protocol drivers in Android will function much like the USB protocol, where modules will be recognized based on different driver "classes," such as those for networking, sensor, imaging, input and others. Some attachable parts may not be recognized by Android. For those parts, separate drivers need to be developed by module makers through emulators. "That will be need to be done in a secure system so the device can't do damage to the system," Grey said. Project Ara is a very disruptive concept, and it turns around conventional thinking on how to build phones, Grey said.Read Replies (0)

writes "Using an Oculus Rift virtual reality headset, Microsoft Kinect, a camera, and a handful of electrical stimulators, a London student's virtual reality system is showing users what it's like to swap bodies. Looking down, they see someone else's arms and legs; looking out, it's someone else's point of view; and when they move their limbs, the body they see does the same (those electrical stimulators mildly shock muscles to force a friend to mirror the user's movements). It's an imperfect system, but a fascinating example of the power of virtual reality. What else might we use VR systems for? Perhaps they'll prove useful in training or therapeutic situations? Or what about with robots, which would be easier to inhabit and control than another human? The virtual body swap may never fully catch on, but generally, virtual reality will likely prove useful for more than just gaming and entertainment."Read Replies (0)

An anonymous reader writes: Amazon has waged a constant battle with publishers over the price of ebooks. They've now publicly laid out their argument and the business math behind it. "We've quantified the price elasticity of e-books from repeated measurements across many titles. For every copy an e-book would sell at $14.99, it would sell 1.74 copies if priced at $9.99. So, for example, if customers would buy 100,000 copies of a particular e-book at $14.99, then customers would buy 174,000 copies of that same e-book at $9.99. Total revenue at $14.99 would be $1,499,000. Total revenue at $9.99 is $1,738,000." They argue that capping most ebooks at $9.99 would be better for everyone, with the money split out 35% to the author, 35% to the publisher, and 30% to Amazon.

A recent post by Instapaper's Marco Arment suggests that design flaws in Apple's App Store are harming the app ecosystem
, and users are suffering because of it. "The dominance and prominence of 'top lists' stratifies the top 0.02% so far above everyone else that the entire ecosystem is encouraged to design for a theoretical top-list placement that, by definition, won’t happen to 99.98% of them." Arment notes that many good app developers are finding continued development to be unsustainable, while scammy apps are encouraged to flood the market.
"As the economics get tighter, it becomes much harder to support the lavish treatment that developers have given apps in the past, such as full-time staffs, offices, pixel-perfect custom designs of every screen, frequent free updates, and completely different iPhone and iPad interfaces. Many will give up and leave for stable, better-paying jobs
. (Many already have.)"
Brent Simmons points out the indie developers have largely given up the dream
of being able to support themselves through iOS development. Yoni Heisler argues that their plight is simply a consequence of ever-increasing competition within the industry
, though he acknowledges that more app curation would be a good thing. What strategies could Apple (and the operators of other mobile application stories) do to keep app quality high?Read Replies (0)

Apache is behind a huge percentage of the world's websites, and the Apache Software Foundation
is the umbrella organization that provides licensing and stucture for many other well-known open source projects ranging from the Apache Web server to Apache OpenOffice to small utilities that aren't household names but are often important to a surprising number of people and companies. Most of us never get to meet the people behind groups like the Apache Software Foundation -- except today we tag along with Tim Lord at OSCON and chat with Apache Software Foundation Executive Vice President Rich Bowen
-- who is also Red Hat's OpenStack Community Liason. (Alternate Video Link

sends word of new quantum mechanical research
in which a neutron is sent along a different path from one of its characteristics
.First, a neutron beam is split into two parts in a neutron interferometer. Then the spins of the two beams are shifted into different directions: The upper neutron beam has a spin parallel to the neutrons’ trajectory, the spin of the lower beam points into the opposite direction. After the two beams have been recombined, only those neutrons are chosen which have a spin parallel to their direction of motion. All the others are just ignored. ... These neutrons, which are found to have a spin parallel to its direction of motion, must clearly have travelled along the upper path — only there do the neutrons have this spin state. This can be shown in the experiment. If the lower beam is sent through a filter which absorbs some of the neutrons, then the number of the neutrons with spin parallel to their trajectory stays the same. If the upper beam is sent through a filter, than the number of these neutrons is reduced.
Things get tricky when the system is used to measure where the neutron spin is located: the spin can be slightly changed using a magnetic field. When the two beams are recombined appropriately, they can amplify or cancel each other. This is exactly what can be seen in the measurement, if the magnetic field is applied at the lower beam – but that is the path which the neutrons considered in the experiment are actually never supposed to take. A magnetic field applied to the upper beam, on the other hand, does not have any effect.Read Replies (0)

writes: U.S. civil rights leader Rev. Jesse Jackson called on the Obama administration Monday to scrutinize the tech industry's lack of diversity. "There's no talent shortage. There's an opportunity shortage," Jackson said, calling Silicon Valley "far worse" than many others, such as car makers that have been pressured by unions. He said tech behemoths have largely escaped scrutiny by a public dazzled with their cutting-edge gadgets. Jackson spoke to press after meeting with Labor Secretary Tom Perez for a review of H-1B visas, arguing that data show Americans have the skills and should have first access to high-paying tech work. Jackson's Rainbow Push Coalition plans to file a freedom-of-information request next month with the EEOC to acquire employment data for companies that have not yet disclosed it publicly, which includes Amazon, Broadcom, Oracle, Qualcomm and Yelp. Unlike the Dept. of Labor, Jackson isn't buying Silicon Valley's argument that minority hiring statistics are trade secrets. Five years after Google's HR Chief would only reassure Congress the company had "a very strong internal Black Googler Network" and its CEO brushed off similar questions about its diversity numbers by saying "we're pretty happy with the way our recruiting work," Google — under pressure from Jackson — fessed up to having a tech workforce that's only 1% Black, apparently par for the course in Silicon Valley.Read Replies (0)
