Designing Collaborative Systems: A Practical Guide to Ethnography introduces a new 'ethnographic' approach that will enable designers to create collaborative and interactive systems, which are employed successfully in real-world settings. This new approach, adapted from the field of social research, considers both the social circumstances and the level and type of human interaction involved, thereby ensuring that future ethnographic systems are as user-friendly and as effective as possible. This book provides the practitioner with an invaluable introduction to this approach, and presents a unique set of practical strategies for incorporating it into the design process. Divided into four distinct sections with practical examples throughout, the book covers:- the requirements problem; - ethnographic practices for describing and analysing cooperative work; - the design process; and - the role of ethnography when evaluating systems supporting cooperative work. "Of the various perspectives that jostle together under the rubric of ethnography, ethnomethodology has often held the most appeal for designers. Yet, surprisingly, there has not been a systematic explication of ethnography and ethnomethodology for the purposes of system design. Andy Crabtree puts this to rights in a comprehensive, informative, and accessible practical guide which will be of great value to not only designers but also the ethnographers who work with them." (Graham Button, Lab. Director, Xerox Research Centre, Europe) "Not only is the book a must for those interested in bringing a social dimension to the system design process, it also makes a significant contribution to ethnomethodology." (Professor John A. Hughes, Lancaster University, UK)

Building on classical queueing theory mainly dealing with single node queueing systems, networks of queues, or stochastic networks has been a field of intensive research over the last three decades. Whereas the first breakthrough in queueing network theory was initiated by problems and work in operations research, the second breakthrough, as well as subsequent major work in the area, was closely related to computer science, particularly to performance analysis of complex systems in computer and communication science.The text reports on recent research and development in the area. It is centered around explicit expressions for the steady behavior of discrete time queueing networks and gives a moderately positive answer to the question of whether there can be a product form calculus in discrete time. Originating from a course given by the author at Hamburg University, this book is ideally suited as a text for courses on discrete time stochastic networks.

The importance of typed languages for building robust software systems is, by now, an undisputed fact. Years of research have led to languages with richly expressive, yet easy to use, type systems for high-level programming languages. Types provide not only a conceptual framework for language designers, but also a ord positive bene ts to the programmer, principally the ability to express and enforce levels of abstraction within a program. Early compilers for typed languages followed closely the methods used for their untyped counterparts. The role of types was limited to the earliest s- ges of compilation, and they were thereafter ignored during the remainder of the translation process. More recently, however, implementors have come to - cognize the importance of types during compilation and even for object code. Several advantages of types in compilation have been noted to date: { They support self-checking by the compiler. By tracking types during c- pilation it is possible for an internal type checker to detect translation errors at an early stage, greatly facilitating compiler development. { They support certi cation of object code. By extending types to the ge- rated object code, it becomes possible for a code user to ensure the basic integrity of that code by checking its type consistency before execution. { They support optimized data representations and calling conventions, even in the presence of modularity. By passing types at compile-, link-, and even run-time, it is possible to avoid compromises of data representation imposed by untyped compilation techniques.

The most famous suppressed book in computer history * Used as an Operating System textbook at MIT"After 20 years, this is still the best expostion of the workings of a 'real' operating system." --- Ken Thompson (Developer of the UNIX operating system)After years of suppression (as trade secrets) by various owners of the UNIX code, this tome has been re-released, and we owe a debt to all involved in making this happen. I consider this to be the single most important book of 1996. Unix Review, June 1997"The Lions book," cherished by UNIX hackers and widely circulated as a photocopied bootleg document since the late 1970's, is again available in an unrestricted edition. This legendary underground classic, reproduced without modification, is really two works in one: the complete source code to an early version (Edition 6) of the UNIX operating system, a treasure in itself a brilliant commentary on that code by John Lionswith additional historical perspective essays added in 1996.Lions' marriage of source code with commentary was originally used as an operating systems textbook, a purpose for which it remains superbly well-suited (as evidenced by it's ongoing use at MIT).
