Features
To ensure the timely publication of articles, Communications created the Virtual Extension to bring readers high-quality articles in an online-only format. The following articles are now available in their entirety to ACM members via the Digital Library.
From Idea to Product; How Schools of Education Can Help CS
Daniel Reed discusses how researchers communicate their project ideas to companies and product groups and get them successfully adopted. Mark Guzdial considers whether schools of education could create more high school CS teachers.

ACM Technews Now Available in the Android Market
After the successful launch of the ACM TechNews iPhone and iPad apps last year, ACM now introduces an Android version for both Android smartphones and tablets. ACM will continue to provide new and compatible options for accessing content on these devices.
Improving Brain-Computer Interfaces
Researchers are demonstrating advances in restorative BCI systems that are giving paralyzed individuals more effective ways to communicate, move, and interact with their environment.
A new DARPA program is teaching cameras visual intelligence — how to spot and understand human behavior.
Technology has created new opportunities to connect and interact. Yet, researchers are increasingly concerned that heavy technology usage is changing people's behavior in less than desirable ways.
A high school student wins first prize from ACM for developing a faster keyboard layout.
Opinion Technology strategy and management
Studying the lessons learned from past and present platform leaders.
Opinion Inside risks
Modernizing the Danish Democratic Process
Examining the socio-technological issues involved in Denmark's decision to pursue the legalization of electronic elections.
Opinion The business of software
There are two situations in software testing that scare testers: when they see "too many" defects and when they do not see "enough."
Opinion Viewpoint
Rebooting the CS Publication Process
A proposal for a new cost-free open-access publication model for computer science papers.
Abstraction in Hardware System Design
Applying lessons from software languages to hardware languages using Bluespec SystemVerilog.
Big data is about more than size, and LINQ is more than up to the task.
Verification of Safety-Critical Software
Avionics software safety certification is achieved through objective-based standards.

From Blitzkrieg to Bitskrieg: The Military Encounter with Computers
Expect more cyberwarfare on the conventional battlefield and less against civilian infrastructure . . . assuming containment is possible.
Research and Advances Contributed articles
How computer scientists can empower journalists, democracy's watchdogs, in the production of news in the public interest.
Research and Advances Review articles
Exploring the connection of biology with reactive systems to better understand living systems.

Technical Perspective: Power Efficiency as the #1 Design Constraint
Moore's Law, and associated observations by Bob Dennard, describe key technical foundations of the semiconductor industry. Taking a step back from these insightful assertions, we can see an even bigger picture emerge related to energy usage and power consumption.

Understanding Sources of Ineffciency in General-Purpose Chips
To better understand what improvement in processor efficiency is possible, we quantify the performance and energy overheads of a 720p HD H.264 encoder running on a CMP system. We explore methods to eliminate these overheads by transforming the CPU into a specialized system for H.264 encoding.

Technical Perspective: A Better Way to Learn Features
A typical machine learning program uses weighted combinations of features to discriminate between classes or to predict real-valued outcomes. The art of machine learning is in constructing the features, and a radically new method of creating features constitutes a major advance.
Research and Advances Research highlights
Unsupervised Learning of Hierarchical Representations with Convolutional Deep Belief Networks
There has been much interest in unsupervised learning of hierarchical generative models such as deep belief networks (DBNs); however, scaling such models to full-sized, high-dimensional images remains a difficult problem.
Research and Advances Research highlights
Technical Perspective: Visual Reconstruction
Nearly 460,000 Flickr pictures were used to create detailed three-dimensional geometry and colors of famous landmarks and monuments in Rome, Venice, and Dubrovnik. To computer vision researchers, these visual reconstructions are a dream come true.
Research and Advances Research highlights
We present a system that can reconstruct 3D geometry from large, unorganized collections of photographs. Our experimental results demonstrate that it is possible to reconstruct city-scale image collections with more than a hundred thousand images in less than a day.
