By Gerhard Weikum (auth.), Reinhard Wilhelm (eds.)

Informatics - 10 Years again, 10 Years Ahead offers a distinct choice of expository papers on significant present concerns within the box of desktop technological know-how and data know-how. The 26 contributions written through prime researchers on own invitation determine the cutting-edge of the sphere through on reflection over the last decade, offering vital effects, determining suitable open difficulties, and constructing visions for the last decade to come.
This e-book marks extraordinary and festive moments: the tenth anniversary of the foreign study and convention middle for computing device technology in Dagstuhl, Germany and the 2000th quantity released within the Lecture Notes in desktop technology series.

Fire in the Valley: The Birth and Death of the Personal Computer

Within the Seventies, whereas their contemporaries have been protesting the pc as a device of dehumanization and oppression, a motley choice of university dropouts, hippies, and electronics fans have been engaged in whatever even more subversive. keen about the assumption of having laptop energy into their very own arms, they introduced from their garages a hobbyist move that grew into an undefined, and eventually a social and technological revolution.

STACS 2006: 23rd Annual Symposium on Theoretical Aspects of Computer Science, Marseille, France, February 23-25, 2006. Proceedings

This e-book constitutes the refereed complaints of the twenty third Annual Symposium on Theoretical points of desktop technological know-how, STACS 2006, held in Marseille, France, in February 2006. The fifty four revised complete papers provided including 3 invited papers have been conscientiously reviewed and chosen from 283 submissions.

Sample text

Conversely, in mobile applications where the data is being created at the endpoints (say, for example, a remote sensing application) data streams into the system in an erratic fashion to be processed, stored, and possibly acted upon by agents residing in the network. Information flows also arise in other applications, such as data dissemination systems in which streams of newly created and modified data must be routed to users and shared caches. Traditional database query processing systems break down in such environments for a number of reasons: First, they are based on static approaches to query optimization and planning.

First, there is a need for synchronization and consistency support. At the center of any collaborative application is a set of shared data items that can be created, accessed, modified, and deleted by participants of the collaboration. This coordination function must be lightweight and flexible so that many different types of interactions can be supported, ranging from unmoderated chat facilities, to full ACID (Atomic, Consistent, Isolated, and Durable) transactions, as provided by traditional database systems.

The challenges being addressed in the Telegraph project include the development of cluster-based and wide-area implementations of the processing engine, the design of fault-tolerance mechanisms (particularly for long-running queries), support for continuous queries over sensor data and for profile-based information dissemination, and user interface issues. Conclusions Ubiquitous computing is a compelling vision for the future that is moving closer to realization at an accelerating pace. The combination of global wireless and wired connectivity along with increasingly small and powerful devices enables a wide array of new applications that will change the nature of computing.
