The Design and Implementation of the 4.4 BSD Operating System (paperback)

This is the eBook version of the printed book. If the print book includes a CD-ROM, this content is not included within the eBook version. This book describes the design and implementation of the BSD operating system--previously known as the Berkeley version of UNIX. Today, BSD is found in nearly every variant of UNIX, and is widely used for Internet services and firewalls, timesharing, and multiprocessing systems. Readers involved in technical and sales support can learn the capabilities and limitations of the system; applications developers can learn effectively and efficiently how to interface to the system; systems programmers can learn how to maintain, tune, and extend the system. Written from the unique perspective of the system's architects, this book delivers the most comprehensive, up-to-date, and authoritative technical information on the internal structure of the latest BSD system. As in the previous book on 4.3BSD (with Samuel Leffler), the authors first update the history and goals of the BSD system. Next they provide a coherent overview of its design and implementation. Then, while explaining key design decisions, they detail the concepts, data structures, and algorithms used in implementing the system's facilities. As an in-depth study of a contemporary, portable operating system, or as a practical reference, readers will appreciate the wealth of insight and guidance contained in this book. Highlights of the book: Details major changes in process and memory management Describes the new extensible and stackable filesystem interface Includes an invaluable chapter on the new network filesystem Updates information on networking and interprocess communication

Operating and Planning Electricity Grids with Variable Renewable Generation

The paper ‘Challenges and Approaches to Electricity Grids Operations and Planning with Increased Amounts of Variable Renewable Generation: Emerging Lessons from Selected Operational Experiences and Desktop Studies’ focuses on analyzing the impacts of variable renewable energy on the operation and planning of the the power system (mostly, generation system). It is aimed at informing stakeholders in power utilities, regulatory bodies and other relevant audiences, on the fundamentals of technical challenges and approaches to operate electricity grids with renewable energy. It covers renewable energy as a whole, but in particular, focusses on wind and solar energy. It also presents three case studies of countries, including China, Gemany and Spain. The total worldwide installed capacity of wind and solar projects is growing rapidly, and several countries are noticing increased penetrations of wind and solar in their electricity generation mix. In addition to operating experience being gained from adding wind and solar capacity, several grid integration studies have been performed that assess potential grid and operating impacts from adding higher amounts of wind and solar capacity. Perhaps just as important, the electric power industry and those that conduct research on grid integration have not found a maximum level of variable generation that can be reliably incorporated, and it is clear that it is as much an economic question (how much cost in additional reserves or grid impacts is acceptable) as a technical question regarding grid operators’ ability to adapt to the new challenges. In addition, while their contributions to capacity or “firm” power and associated costs are different from those of conventional power sources, variable renewable generation technologies can contribute to long-term system adequacy and security. The paper describes on the contribution of variable power sources to long-term supply adequacy requirements, i.e. how much sources like wind and solar power contribute to “firm supply” in a system. It also describes methods to find out to what extent they contribute and at what cost. It also aims at providing indicative answers to how costs to system operations be determined and when and how an integration study be done to estimate the short-term reserve costs of renewable energy.The concepts in the paper should be of interest, especially to grid planers. For grid operators, the paper summarizes a menu of strategies that the operational practices and desktop research tell about managing wind in a system at different levels of penetration. It also elucidates available strategies, amongst other crucial questions of operational impacts and challenges that operators need to be aware of, to integrate variable generation.

Mechanisms for Reliable Distributed Real-Time Operating Systems

Mechanisms for Reliable Distributed Real-Time Operating Systems: The Alpha Kernel deals with the Alpha kernel, a set of mechanisms that support the construction of reliable, modular, decentralized operating systems for real-time control applications. An initial snapshot of the kernel design and implementation is provided. Comprised of seven chapters, this volume begins with a background on the Alpha operating system kernel and its implementation, followed by a description of the programming abstractions created for the Alpha kernel. The third chapter defines the client interface provided by the kernel in support of the given programming abstractions, while the fourth chapter focuses on the functional design of the kernel. The hardware on which the kernel was constructed, as well as the implications of this hardware on the design and implementation of the kernel, is also examined. The final chapter compares Alpha with other relevant operating systems such as Hydra, Cronus, Eden, Argus, Accent, and Locus. This book will appeal to computer scientists, systems designers, and undergraduate and graduate students of computer science.

Operating Instructions

With the same brilliant combination of humor and warmth she brought tobestseller Bird by Bird , Anne Lamott gives us a smart, funny, and comforting chronicle of single motherhood. It's not like she's the only woman to ever have a baby. At thirty-five. On her own. But Anne Lamott makes it all fresh in her now-classic account of how she and her son and numerous friends and neighbors and some strangers survived and thrived in that all important first year. From finding out that her baby is a boy (and getting used to the idea) to finding out that her best friend and greatest supporter Pam will die of cancer (and not getting used to that idea), with a generous amount of wit and faith (but very little piousness), Lamott narrates the great and small events that make up a woman's life. "Lamott has a conversational style that perfectly conveys her friendly, self-depricating humor." -- Los Angeles Times Book Review "Lamott is a wonderfully lithe writer .... Anyone who has ever had a hard time facing a perfectly ordinary day will identify." -- Chicago Tribune

System Architecture

The pillars of the bridge on the cover of this book date from the Roman Empire and they are in daily use today, an example of conventional engineering at its best. Modern commodity operating systems are examples of current system programming at its best, with bugs discovered and fixed on a weekly or monthly basis. This book addresses the question of whether it is possible to construct computer systems that are as stable as Roman designs. The authors successively introduce and explain specifications, constructions and correctness proofs of a simple MIPS processor; a simple compiler for a C dialect; an extension of the compiler handling C with inline assembly, interrupts and devices; and the virtualization layer of a small operating system kernel. A theme of the book is presenting system architecture design as a formal discipline, and in keeping with this the authors rely on mathematics for conciseness and precision of arguments to an extent common in other engineering fields. This textbook is based on the authors' teaching and practical experience, and it is appropriate for undergraduate students of electronics engineering and computer science. All chapters are supported with exercises and examples.

Operating Rules in Organizations

When economists claim that rules are coordinating devices, they do not explain how those rules operate in the reality of organizational life. Rules do not indicate behaviour, since their most important characteristic is their remoteness from the solution. Thus, rules are merely frameworks for action requiring constant interpretation. This book is grounded in Wittgenstein's understanding of rules as having significance only in the course of their application. It focuses on two kinds of rules - macroeconomic and microeconomic - through detailed case studies of wage indexation and labour productivity.
