DEPARTMENT: Editor's letter
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?
DEPARTMENT: Publisher's corner
This issue marks the first anniversary of the completely revamped Communications, so I thought it would be appropriate to report on how we're doing so far.

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.
Computer technology has enhanced lives in countless ways, but some experts believe it might be affecting people's ability to think deeply.
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.
Why the Google Book Search settlement agreement under consideration could result in an extensive restructuring of the book industry.

In one scene from The Matrix
, two leaders of the human resistance are trapped on the roof of a skyscraper. The only means of escape is by helicopter, which neither can operate …
Autonomous helicopter flight is widely regarded to be a highly challenging control problem. As helicopters are highly unstable and exhibit complicated dynamical behavior, it is particularly difficult to design controllers that …
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 …
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 …

The "Internet of Things," once reality, will have to rely on a global IT infrastructure that provides information about all those "things" in a secure and reliable manner. The EPCglobal Network is a proposal for a widely distributed …
Wireless service providers have invested heavily in upgrading their networks to the next generation standard (3G). However, consumer interest in data services does not paint a rosy picture for the providers.
The literature in the field of project management, especially the literature about risk, is particularly rich in advice about addressing software failure …
Since SCADA networks were initially designed with little attention to security, they can be easy targets of attacks by terrorist groups.
Decades of evidence reveal a shockingly low success rate for software projects. Although the record is slowly improving, much work remains before software project success becomes the norm rather than the exception.
In modern information societies, the ethical integrity and accountability of IT professionals is particularly important, given the extensive reliance of individuals as well as organisations and governments on various forms of …
