Well suited to medium-scale general purpose computing, the Unix time sharing operating system is deservedly popular with academic institutions, research laboratories, and commercial establishments alike. Its user com munity, until recently a brotherhood of experienced computer profes sionals, it now attracting many people concerned with computer appli cations rather than the computer systems themselves. This book is intended for that new audience, people who have never encountered the Unix system before but who do have some acquaintance with computing. While helping beginning users get started is the primary aim of this book, it is also intended to serve as a handy reference subsequently. However, it is not designed to replace the definitive Unix system docu mentation. Unix operating systems now installed in computing centers, offices, and personal computers come in three related but distinct breeds: Seventh Edition Unix, Berkeley 4.2 BSD, and System V. These differ from each other in details, even though their family resemblance is strong. This book emphasizes System V, while paying heed to its two popular cousins. It also includes a few facilities in wide use, but not included in the normal system releases. Individual details, of course, must be found in the manuals supplied with each system."

This volume contains the proceedings of an international workshop on "Experiences with Distributed Systems" held September 28-30, 1987, at the University of Kaiserslautern. The workshop was jointly sponsored and organized by the Sonderforschungsbereich 124 "VSLI-Entwurfsmethoden und ParallelitAt" and the European Network Center (ENC) of the IBM Corporation, Heidelberg. The objective of the workshop was to bring together researchers who had gathered substantial experience with the implementation of distributed systems. The emphasis was put on the exchange of (good and bad) experiences with existing concepts in distributed system design rather than presenting new ideas. Participation in the workshop was by invitation only. The presentations can be roughly categorized as reports on a specific project or reports on experiences with a certain topic accumulated through several projects. Other lectures treated general topics such as fault tolerance, design principles for distributed languages and systems, and distributed databases.

Die Leistung von Computersystemen ist die ausschlaggebende Groe fur ihren Einsatz. Zur Messung der Leistung wird sehr oft das Benchmark-Verfahren als Standard-Tool eingesetzt, obwohl allgemein bekannt ist, dass die entsprechenden Ergebnisse nur eine sehr beschrankte Aussagekraft haben - dafur spricht naturlich ihre starke Orientierung an der Praxis. Modellbildende Techniken werden haufig zu Recht als "Mathematik-lastig" empfunden und suggerieren zudem eine Genauigkeit jenseits der Realitat. Dabei liegt es auf der Hand, dass beide Standpunkte sich erganzen und zusammen eine wesentlich bessere Messung, Analyse und Bewertung gestatten. Anhand dieser Konzeption erlautert der Autor bessere Methoden zur Leistungsbewertung von Computersystemen.

This volume contains revised versions of presentations at the International Workshop on Analogical and Inductive Inference (AII '86) held in Wendisch-Rietz, GDR, October 16-10, 1986. Inductive inference and analogical reasoning are two basic approaches to learning algorithms. Both allow for exciting problems and promising concepts of invoking deeper mathematical results for considerable advances in intelligent software systems. Hence analogical and inductive inference may be understood as a firm mathematical basis for a large variety of problems in artificial intelligence. While the papers on inductive inference contain technical results and reflect the state of the art of this well-developed mathematical theory, those devoted to analogical reasoning reflect the ongoing process of developing the basic concepts of the approach. The workshop thus contributes significantly to the advancement of this field.

This volume contains the proceedings of the Second International Conference on Rewriting Techniques and Applications, "RTA 87," held in Bordeaux, France, May 1987.

A good introduction to a new product or concept is vital. This is particularly true for a versatile software system such as UNIX. UNIX provides the depth and intelligence to make your computer work hard for you. It will help you create software and help you use your office automation equipment to create and edit documents. For your intro duction to UNIX, you want a great little book. That is what this work is meant to be. This book is designed for non-computer specialists, especially for executives, ad ministrators and managers who want to make better use of their software specialists and experts. The way this Springer edition has come to be published is itself a story. Back about 1980, the founder and president of one of the more successful microcomputer companies, Mr. Kazue Ishii of CEC, wanted to start somethig that would be brilliant, sophisticated, innovative, and which would grow steadily. Out of many proposals, the one he accepted happened to be mine. The proposal was to build a family of network workstations for computer-aided design/manufacturing and office automation. UNIX was to be used as a software generator. But he had a hard time understanding UNIX, what good it is and how good it is ... Spending a significant amount of time with a popular computer columnist, Miss Yukari Shirota, I compiled this book for him. I found this book generally useful for top executives, managers, planners and office administrators whose background is outside software engineering. Dr.

With this book, Christopher Kormanyos delivers a highly practical guide to programming real-time embedded microcontroller systems in C++. It is divided into three parts plus several appendices. Part I provides a foundation for real-time C++ by covering language technologies, including object-oriented methods, template programming and optimization. Next, part II presents detailed descriptions of a variety of C++ components that are widely used in microcontroller programming. It details some of C++'s most powerful language elements, such as class types, templates and the STL, to develop components for microcontroller register access, low-level drivers, custom memory management, embedded containers, multitasking, etc. Finally, part III describes mathematical methods and generic utilities that can be employed to solve recurring problems in real-time C++. The appendices include a brief C++ language tutorial, information on the real-time C++ development environment and instructions for building GNU GCC cross-compilers and a microcontroller circuit. For this fourth edition, the most recent specification of C++20 is used throughout the text. Several sections on new C++20 functionality have been added, and various others reworked to reflect changes in the standard. Also several new example projects ranging from introductory to advanced level are included and existing ones extended, and various reader suggestions have been incorporated. Efficiency is always in focus and numerous examples are backed up with runtime measurements and size analyses that quantify the true costs of the code down to the very last byte and microsecond. The target audience of this book mainly consists of students and professionals interested in real-time C++. Readers should be familiar with C or another programming language and will benefit most if they have had some previous experience with microcontroller electronics and the performance and size issues prevalent in embedded systems programming.
