The most popular content on Communications' site is something many readers know nothing about.
Computer scientists are now making intellectual contributions to a wide range of other disciplines, including evolutionary theory, physics, and economics.
Countries use Internet censorship to dominate the political dialogue, but also to create favorable conditions for government-controlled businesses.
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.
Charles P. Thacker talks about the importance of simplicity, reusable tools, thinking broadly, and his practice of Tom Sawyering.
Eric Brewer's latest project involves designing and deploying low-cost wireless infrastructure in developing regions.
ACM joined forces with the British Computer Society to deliver its first academic research conference in Europe.
COLUMN: Technology strategy and management
Choosing between outsourcing and shared services has significant implications for long-term corporate strategy.
COLUMN: Computing ethics
Technological change results in changes in expectations, in this case affecting the workplace.
COLUMN: Legally speaking
Considering the precedent that could be established by approval of the controversial Google book settlement.
COLUMN: Broadening participation
Introducing CMD-IT, a new center focused on synergistic activities related to ethnic minorities and people with disabilities.
Reflections on the (experimental) scientific method in computer science.
COLUMN: Distinguished members
ACM's Distinguished Member Recognition Program recognizes members in three categories: Educator, Engineer, and Scientist. Each category comes with a unique set of criteria.
Maybe it's Fortran. Or maybe it just doesn't matter.
Heat maps are a unique and powerful way to visualize latency data. Explaining the results, however, is an ongoing challenge.
Think you've mastered the art of server performance? Think again.
SECTION: Contributed articles
Innate understanding of concurrency helps beginners solve CS problems with multiple processes executing at the same time.
Interactive computer graphics would rival word-processing and presentation programs for everyday communications.
SECTION: Review articles
A new era of theoretical computer science addresses fundamental problems about auctions, networks, and human behavior.
SECTION: Research highlights
Multithreaded programs that communicate through shared memory are pervasive. Today they are the most obvious route to using multiple available processor cores …
Exploiting the multiprocessors that have recently become ubiquitous requires high-performance and reliable concurrent systems code. However, concurrent programming, which is always challenging, is made much more so by two problems …
As predicted by Intel's Gordon Moore in 1965, the number of transistors that can be integrated on one die continues to double approximately every two years. Amazing to some …
Memory scaling is in jeopardy as charge storage and sensing mechanisms become less reliable for prevalent memory technologies. In contrast, phase change memory relies on programmable resistances, as well as scalable current and …
COLUMN: Last byte
Charles P. Thacker discusses the legendary Alto personal computer, the invention of the Ethernet, and his current research on multicore architectures.
SECTION: Virtual extension
A relatively new form of IS outsourcing, Application Services Provision (ASP), provides applications to multiple entities from its data center across a wide area network.
Most large companies have adopted some form of enterprise resource planning (ERP) system. While the potential benefits of ERP have been extolled frequently, only limited evidence states that implementation of ERP does, on average …
The growing commoditisation of services has transformed the competition for market share from focusing on the quality of services to the creation of memorable experiences. The economic value of the experience economy lies in …
Tagging is gaining much popularity in recent years. Studies have suggested several factors that motivate user tagging. However, to date no quantitative study has assessed the strength of the effects of each motivation on levels …
Computer science applications are becoming more network centric, ubiquitous, knowledge intensive, and computing demanding. This will result in an ecosystem of pervasive applications and services that professionals and end-users …
Student enrollment in college computer science and information technology programs are in a downward trend in most developed countries. This article examines the Cisco Networking Academy to understand what lessons we can draw …
The importance of electronically stored information (ESI) in litigation has increased greatly over the past decade. Managing discovery of electronic information requires close coordination among managers with widely diverse technical …
