You’ll never watch alone: media and community in the sports bar

This paper positions itself within the ongoing debate about the impact of media on community generated by Robert Putnam’s research. Accordingly, the increasing availability of sophisticated means of communication has led the progressive substitution of indirect interactions for direct interactions in shared space, thereby eroding an essential basis of community. In contrast, other theoretical perspectives have presented communication technologies as either enhancing community by altering the field of possible social interactions or incapable of replacing direct interactions. This debate is addressed through an ethnography of fans who gathered at a sports bar to watch the World Cup. Observations revealed that while televised broadcasts served as a primary motivation for attendance and a centrepiece of subsequent interactions, patrons did not watch alone; they watched with each other.     

Dimensions of variability in embedded operating systems

Design, implementation, and re-engineering of operating systems are still an ambitious undertaking. Despite, or even because, of the long history of theory and practice in this field, adapting existing systems to environments of different conditions and requirements as originally specified or assumed, in terms of functional and/or non-functional respects, is anything but simple. Especially this is true for the embedded systems domain which, on the one hand, calls for highly specialized and application-aware system abstractions and, on the other hand, cares a great deal for easily reusable implementations of these abstractions. The latter aspect becomes more and more important as embedded systems technology is faced with an innovation cycle decreasing in length. Software for embedded systems needs to be designed for variability, and this is in particular true for the operating systems of this domain. The paper discusses dimensions of variability that need to be considered in the development of embedded operating systems and presents approaches that aid construction and maintenance of evolutionary operating systems.
