Editorial Pointers

Ubiquitous objects and mobile communication devices are fast becoming part of the invisible fabric of everyday life. While each comes with a unique set of operating requirements, we’ve come to expect them to work autonomously as well as in concert with other devices already part of our personal operating needs. As a result, finding ways […]

The things Peter G. Neumann described as risks in his "Inside Risks" column ("Risks Relating to System Compositions," July 2006) I would generally characterize as stupidity. Unfortunately, too many software-oriented people, especially hackers and other free spirits, take an approach that is the equivalent of playing Russian Roulette, inevitably causing most of their own problems.

Research and Advances Privacy and security in highly dynamic systems Sep 1 2006

The IT community is accustomed to looking at the evolution of computers referring to the "laws" and "theories" of Moore and Bell. However, in the age of ad hoc and spontaneous networking and miniaturization, additional non-hardware-based dimensions may help to influence our conceptions of future developments in computing. The theory of computer-class formation from 1975 […]
