    This report summarizes the viewpoints and insights gathered in the Dagstuhl Seminar on Atomicity in System Design and Execution, which was attended by 32 people from four different scientific communities: database and transaction processing systems, fault tolerance and dependable systems, formal methods for system design and correctness reasoning, and hardware architecture and programming languages. Each community presents its position in interpreting the notion of atomicity and the existing state of the art, and each community identifies scientific challenges that should be addressed in future work. In addition, the report discusses common themes across communities and strategic research problems that require multiple communities to team up for a viable solution. The general theme of how to specify, implement, compose, and reason about extended and relaxed notions of atomicity is viewed as a key piece in coping with the pressing issue of building and maintaining highly dependable systems that comprise many components with complex interaction patterns

    From “the dialectics of nature” to the inorganic gene

    Get PDF
    The concept of projection from one space to another, with a consequent loss of information, can be seen in the relationships of gene to protein and language description to real situation. Such a transformation can only be reversed if extra external information is re-supplied. The genetic algorithm embodying this idea is now used in applied mathematics for exploring a configuration space. Such a dialectic – transformation back and forth between two kinds of description – extends the traditional Hegelian concept used by Engels and others of change as resulting from a resolution of the conflict of two opposing tendencies and provides for evolution of the joint system

    The Dagstuhl Perspectives Workshop "Online Privacy: Towards Informational Self-Determination on the Internet" (11061) has been held in February 6-11, 2011 at Schloss Dagstuhl. 30 participants from academia, public sector, and industry have identified the current status-of-the-art of and challenges for online privacy as well as derived recommendations for improving online privacy. Whereas the Dagstuhl Manifesto of this workshop concludes the results of the working groups and panel discussions, this article presents the talks of this workshop by their abstracts

    Ronald Gonzalez: Private Collection

    Full text link
    In Ronald Gonzalez’s latest series of sculptures, old leather satchels, small antiquated appliances, dulled tools, bicycle handles, shoes, a fencing mask, an accordion, a bicycle seat, a toaster and helmets, among other various found parts and outdated detritus are combined to evoke the heads and torsos of human-like forms. The viewer identifies the components at once as what the objects literally are as well as the specific body parts they figuratively describe. As such, his art calls for an exercise in perceptual shifts that allow for more than one visual interpretation. While some objects are manipulated, others are left intact, as Gonzalez creates paradoxically human and strangely inanimate assemblages.
