Difference Engine: Harnessing Memory Redundancy in Virtual Machines
Virtual machine monitors are a popular platform for Internet hosting centers and cloud-based compute services. But main memory is not amenable to multiplexed hardware resources and is often a bottleneck in achieving higher degrees of consolidation.
Technical Perspective: A VM ‘Engine’ That Makes a Difference
The past decade has witnessed a renaissance in server virtualization. Diwaker Gupta et al. present a novel approach for significantly improving the efficiency of virtualized servers.
Nonparametric Belief Propagation
Probabilistic graphical models and algorithms for approximate inference have proven to be powerful tools in a wide range of applications in statistics and AI. However, applying these methods to models with continuous variables remains a challenging task.
Performance Evaluation and Model Checking Join Forces
A call for the perfect marriage between classical performance evaluation and state-of-the-art verification techniques.
Sensor-equipped bicycles are providing valuable data to cyclists, city planners, and computer scientists.
Computational neuroscientists are learning that the brain is like a computer, except when it isn't.
Thinking Clearly About Performance, Part 1
Improving the performance of complex software is difficult, but understanding some fundamental principles can make it easier.

Innovations in playing the game "Go" using Monte Carlo Tree Search and parallel algorithms.
Seven Principles For Selecting Software Packages
Everything you always wanted to know but were afraid to ask about the decision-making process.
Looking Beyond Stereoscopic 3D’s Revival
Researchers working in vision and graphics are attempting to develop new techniques and technologies to overcome the current limitations in stereoscopic 3D.
Rights For Autonomous Artificial Agents?
The growing role of artificial agents necessitates modifying legal frameworks to better address human interests.
How a Service-Oriented Architecture May Change the Software Development Process
Software development practices have evolved substantially during the past decade. As so called "agile" approaches have gained more acceptance, the service-oriented approach to IT architecture has become an important alternative to traditional software development.
thinkflickrthink: A Case Study on Strategic Tagging
The growth both in quantity and diversity of online communities across the World Wide Web, along with a number of new technologies that enhance both social interaction and content management, have bred an array of increasingly participatory practices.

Robotics will inspire dramatic changes in the CS curriculum.
Personal Robots: Newest Cs1 Teaching Tool
The Institute for Personal Robots in Education has developed a curriculum, software, and plug-in board for an off-the-shelf personal robot that it hopes will make computer science more tantalizing to undergraduates.
Q&A: From Single Core to Multicore
Charles P. Thacker discusses the legendary Alto personal computer, the invention of the Ethernet, and his current research on multicore architectures.
Is Computer Science Truly Scientific?
Reflections on the (experimental) scientific method in computer science.
Interactive computer graphics would rival word-processing and presentation programs for everyday communications.
ACM joined forces with the British Computer Society to deliver its first academic research conference in Europe.
Mainstreaming Augmented Reality
Advancements in computer vision, object recognition, and related technologies are leading to new levels of sophistication in augmented-reality applications and presenting new ways for humans to relate to the natural world.
Technological change results in changes in expectations, in this case affecting the workplace.
Shape the Future of Computing
ACM encourages its members to take a direct hand in shaping the future of the association. There are more ways than ever to get involved.
Get InvolvedCommunications of the ACM (CACM) is now a fully Open Access publication.
By opening CACM to the world, we hope to increase engagement among the broader computer science community and encourage non-members to discover the rich resources ACM has to offer.
