Adventures of small toy rabbit lost by a 5-yr-old boy as he sets off on holiday with his parents. The little stuffed toy can communicate with animals but not humans. Has encounters with many wild creatures. Returns to child owner by circuitous route.

An argument that the material arrangements of information—how it is represented and interpreted—matter significantly for our experience of information and information systems. Virtual entities that populate our digital experience, like e-books, virtual worlds, and online stores, are backed by the large-scale physical infrastructures of server farms, fiber optic cables, power plants, and microwave links. But another domain of material constraints also shapes digital living: the digital representations sketched on whiteboards, encoded into software, stored in databases, loaded into computer memory, and transmitted on networks. These digital representations encode aspects of our everyday world and make them available for digital processing. The limits and capacities of those representations carry significant consequences for digital society. In The Stuff of Bits, Paul Dourish examines the specific materialities that certain digital objects exhibit. He presents four case studies: emulation, the creation of a “virtual” computer inside another; digital spreadsheets and their role in organizational practice; relational databases and the issue of “the databaseable”; and the evolution of digital networking and the representational entailments of network protocols. These case studies demonstrate how a materialist account can offer an entry point to broader concerns—questions of power, policy, and polity in the realm of the digital.

Bits and Pieces tells the story of chiptune, a style of lo-fi electronic music that emerged from the first generation of video game consoles and home computers in the late 1970s and early 1980s. Through ingenuity and invention, musicians and programmers developed code that enabled the limited hardware of those early 8-bit machines to perform musical feats that they were never designed to achieve. In time, that combination of hardware and creative code came to define a unique 8-bit sound that imprinted itself on a generation of gamers. For a new generation of musicians, this music has currency through the chipscene, a vibrant musical subculture that repurposes obsolete gaming hardware. It's performative: raw and edgy, loaded with authenticity and driven by a strong DIY ethic. It's more punk than Pac-Man, and yet, it's part of that same story of ingenuity and invention; 8-bit hardware is no longer a retired gaming console, but a quirky and characterful musical instrument. Taking these consoles to the stage, musicians fuse 8-bit sounds with other musical styles - drum'n'bass, jungle, techno and house - to create a unique contemporary sound. Analyzing musical structures and technological methods used with chiptune, Bits and Pieces traces the simple beeps of the earliest arcade games, through the murky shadows of the digital underground, to global festivals and movie soundtracks.

In scientific computing (also known as computational science), advanced computing capabilities are used to solve complex problems. This self-contained book describes and analyzes reported software failures related to the major topics within scientific computing: mathematical modeling of phenomena; numerical analysis (number representation, rounding, conditioning); mathematical aspects and complexity of algorithms, systems, or software; concurrent computing (parallelization, scheduling, synchronization); and numerical data (such as input of data and design of control logic). Readers will find lists of related, interesting bugs, MATLAB examples, and “excursions” that provide necessary background, as well as an in-depth analysis of various aspects of the selected bugs. Illustrative examples of numerical principles such as machine numbers, rounding errors, condition numbers, and complexity are also included.

'Blown to Bits' is about how the digital explosion is changing everything. The text explains the technology, why it creates so many surprises and why things often don't work the way we expect them to. It is also about things the information explosion is destroying: old assumptions about who is really in control of our lives.

This book constitutes the refereed proceedings of the 5th International Workshop on Experimental and Efficient Algorithms, WEA 2006, held in Menorca, Spain, May 2006. The book presents 26 revised full papers together with 3 invited talks. The application areas addressed include most fields applying advanced algorithmic techniques, such as combinatorial optimization, approximation, graph theory, discrete mathematics, scheduling, searching, sorting, string matching, coding, networking, and more.
