The Critical Elements of the Patch Management Process
Today most security incidents are caused by flaws in software, called vulnerabilities. It is estimated that there are as many as 20 flaws per thousand lines of software code.
Learning to Build an IT Innovation Platform
Information Technology (IT) pervades every aspect of a firm's value chain as a vast electronic network of interconnected applications and data. Managers perceive the immense potential of this complex infrastructure to enhance products and processes and create altogether new ones.
Global Software Development: Where Are the Benefits?
Global Software Development is increasingly becoming the normal practice in the software industry.
Ranking Billions of Web Pages Using Diodes
Because of the web's rapid growth and lack of central organization, Internet search engines play a vital role in assisting the users of the Web in retrieving relevant information out of the tens of billions of documents available.
How to Harness Petaflop Performance
Several petascale computers are up and running, and others are sure to follow. All of them face many unique challenges in trying to harness a petaflop.
Practice Makes Perfect, Even For Brain-Controlled Prosthetics
Those who learn by repetition rely on "muscle memory," a sense that practice trains muscles to perform specific actions without thought. But does muscle memory exist if no actual muscles are involved? According to a paper published in the peer-reviewed journal PLoS Biology, the answer is a clear "yes." These findings strengthen hope for the future of brain-controlled prosthetics, or "neuroprosthetics", and may aid the development of robotic body extensions whose control is truly intuitive.
Award-Winning Paper Reveals Key to Netflix Prize
When the organizers of the Netflix Prize contest announced late last week that one team had met the requirement for the $1 million Grand Prize, Yehuda Koren, a member of the seven-person multinational team, was in Paris to present a paper at KDD-09, the 15th ACM SIGKDD Conference on Knowledge Discovery and Data Mining. The ideas he laid out won the conference's Best Paper Award — and, not coincidentally, had much to do with reaching the contest's target of improving the accuracy of Netflix movie recommendations by 10 percent.
Open, Closed, or Clopen Access?
A frequent question I hear about Communications, and about ACM publishing in general, involves its access model. I am asked: "Why don't you adopt the open-access model?" Good question! Why don't we?
Inspire with Introductory Computer Science
Mark Guzdial's Viewpoint "Teaching Computing to Everyone" (May 2009) was interesting reading but included several implications, possibly unintentional, that should be corrected.
Sharing Ideas, Writing Apps, and Creating a Professional Web Presence
Greg Linden reveals his new approach to reading research papers, Mark Guzdial discusses how to encourage students to write computer programs, and Tessa Lau shares her ideas about the importance of Web visibility.
My old boss was thrilled the first time he saw the image of a spinning globe online. But that was long ago, when Web users were explorers, the Internet was a place of discovery, and an animated .gif could muster boyish enthusiasm. Expectations are much higher and far more sophisticated now that users have visited […]
Contemporary Approaches to Fault Tolerance
Thanks to computer scientists like Barbara Liskov, researchers are making major progress with cost-efficient fault tolerance for Web-based systems.
Several software projects are narrowing the performance gap between browser-based applications and their desktop counterparts. In the process, they're creating new ways to improve the security of Web-based computing.
Barbara Liskov muses about the creative process of problem solving, finding the perfect design point, and pursuing a research path.
Jon Kleinberg is honored for his pioneering research on the Web and social networking.
Among this year's distinguished honorees are Barbara Liskov of Massachusetts Institute of Technology and Jon Kleinberg of Cornell University.
A guide to playing the ploys frequently employed by cliché-driven management.
The Five-Minute Rule 20 Years Later
Revisiting Gray and Putzolu's famous rule in the age of Flash.
Steps Toward Self-Aware Networks
Network software adapts to user needs and load variations and failures to provide reliable communications in largely unknown networks.
The Metropolis Model: A New Logic For Development of Crowdsourced Systems
It takes a city of developers to build a big system that is never done.
Probabilistic Databases: Diamonds in the Dirt
Treasures abound from hidden facts found in imprecise data sets.
Technical Perspective: A Compiler’s Story
In the early 1970s, pioneers like Floyd, Dijkstra, and Hoare argued that programs should be formally specified and proven correct. But for the past 40 years, most of the computer science community has discounted this vision as an unrealistic goal.
Formal Verification of a Realistic Compiler
This paper reports on the development and formal verification of CompCert, a compiler from Clight (a large subset of the C programming language) to PowerPC assembly code, using the Coq proof assistant both for programming the compiler and for proving its correctness.
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.
