Download or read book The Multics System written by Elliott Irving Organick and published by MIT Press (MA). This book was released on 1972 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides an overview of the Multics system developed at M.I.T.—a time-shared, general purpose utility-like system with third generation software. The advantage that this new system has over its predecessors lies in its expanded capacity to manipulate and file information on several levels and to police and control access to data in its various files. On the invitation of M.I.T.'s Project MAC, Elliott Organick developed over a period of years an explanation of the workings, concepts, and mechanisms of the Multics system. This book is a result of that effort, and is approved by the Computer Systems Research Group of Project MAC. In keeping with his reputation as a writer able to explain technical ideas in the computer field clearly and precisely, the author develops an exceptionally lucid description of the Multics system, particularly in the area of "how it works." His stated purpose is to serve the expected needs of designers, and to help them "to gain confidence that they are really able to exploit the system fully, as they design increasingly larger programs and subsystems." The chapter sequence was planned to build an understanding of increasingly larger entities. From segments and the addressing of segments, the discussion extends to ways in which procedure segments may link dynamically to one another and to data segments. Subsequent chapters are devoted to how Multics provides for the solution of problems, the file system organization and services, and the segment management functions of the Multics file system and how the user may employ these facilities to advantage. Ultimately, the author builds a picture of the life of a process in coexistence with other processes, and suggests ways to model or construct subsystems that are far more complex than could be implemented using predecessor computer facilities. This volume is intended for the moderately well-informed computer user accustomed to predecessor systems and familiar with some of the Multics overview literature. While not intended as a definitive work on this living, ever-changing system, the book nevertheless reflects Multics as it has been first implemented, and should reveal its flavor, structure and power for some time to come.

Available in PDF, EPUB and Kindle. Book excerpt: Operating systems provide the fundamental mechanisms for securing computer processing. Since the 1960s, operating systems designers have explored how to build "secure" operating systems - operating systems whose mechanisms protect the system against a motivated adversary. Recently, the importance of ensuring such security has become a mainstream issue for all operating systems. In this book, we examine past research that outlines the requirements for a secure operating system and research that implements example systems that aim for such requirements. For system designs that aimed to satisfy these requirements, we see that the complexity of software systems often results in implementation challenges that we are still exploring to this day. However, if a system design does not aim for achieving the secure operating system requirements, then its security features fail to protect the system in a myriad of ways. We also study systems that have been retrofit with secure operating system features after an initial deployment. In all cases, the conflict between function on one hand and security on the other leads to difficult choices and the potential for unwise compromises. From this book, we hope that systems designers and implementors will learn the requirements for operating systems that effectively enforce security and will better understand how to manage the balance between function and security.

Download or read book A Primer for Computational Biology written by Shawn T. O'Neil and published by . This book was released on 2017-12-21 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Primer for Computational Biology aims to provide life scientists and students the skills necessary for research in a data-rich world. The text covers accessing and using remote servers via the command-line, writing programs and pipelines for data analysis, and provides useful vocabulary for interdisciplinary work. The book is broken into three parts: Introduction to Unix/Linux: The command-line is the "natural environment" of scientific computing, and this part covers a wide range of topics, including logging in, working with files and directories, installing programs and writing scripts, and the powerful "pipe" operator for file and data manipulation. Programming in Python: Python is both a premier language for learning and a common choice in scientific software development. This part covers the basic concepts in programming (data types, if-statements and loops, functions) via examples of DNA-sequence analysis. This part also covers more complex subjects in software development such as objects and classes, modules, and APIs. Programming in R: The R language specializes in statistical data analysis, and is also quite useful for visualizing large datasets. This third part covers the basics of R as a programming language (data types, if-statements, functions, loops and when to use them) as well as techniques for large-scale, multi-test analyses. Other topics include S3 classes and data visualization with ggplot2.

Available in PDF, EPUB and Kindle. Book excerpt: This volume describes General Electric Corporation’s venture into developing second and third generation mainframe computer systems. The General Electric Corporation (GE), which began its life as the Edison Electric Co., was long involved in electrical appliances and industrial machines. It was also a founder of the Radio Corporation of America, which eventually became one of its competitors, and developed many electrical systems in order to control different types of industrial machines. Its breakthrough into computing came with its winning bid to provide the computing systems for the Electronic Recording Method of Accounting) system developed for the Bank of America by the Stanford Research Institute. The success of this project led GE to develop the GE-200 series which was the foundation for commercial timesharing. The GE-235 was selected by Dartmouth for its Dartmouth Time Sharing System (DTSS), an innovative academic time-sharing system. BASIC was developed on the GE-235 computer system under DTSS. GE enhanced it to develop its Mark II/III Time Sharing System, apparently the first commercial time sharing service in the world. GE develop the GE-300/-400 systems for industrial process control. The GE-600 series replaced the GE-200 series and demonstrated innovation in time-sharing systems. The GE-645 was selected to host Multics, which was developed by MIT. However, GE felt that it could not compete in computing against IBM, Univac, and other mainframes competitors, so it folded its tent and sold its Computer Division to Honeywell, Inc. Nevertheless, GE will be remembered for many innovations which continue to be used in modern computing systems.

Download or read book A Paging Experiment with the Multics System written by F. J. Corbató and published by . This book was released on 1968 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The paging algorithm currently used in the Multics system is described in considerable detail. This algorithm can be viewed parametrically such that at one extreme it has a page removal strategy of first-in-first-out (FIFO) and at the other extreme a removal strategy of least-recently-used (LRU). Two brief experiments are described where the effects of parametric variation were observed with results which indicate that a particularly simple case of the algorithm gives efficient performance.

Book excerpt: Over the past two decades, there has been a huge amount of innovation in both the principles and practice of operating systems Over the same period, the core ideas in a modern operating system - protection, concurrency, virtualization, resource allocation, and reliable storage - have become widely applied throughout computer science. Whether you get a job at Facebook, Google, Microsoft, or any other leading-edge technology company, it is impossible to build resilient, secure, and flexible computer systems without the ability to apply operating systems concepts in a variety of settings. This book examines the both the principles and practice of modern operating systems, taking important, high-level concepts all the way down to the level of working code. Because operating systems concepts are among the most difficult in computer science, this top to bottom approach is the only way to really understand and master this important material.
Download or read book Linux and the Unix Philosophy written by Mike Gancarz and published by Elsevier. This book was released on 2003-08-15 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unlike so many books that focus on how to use Linux, Linux and the Unix Philosophy explores the "way of thinking that is Linux" and why Linux is a superior implementation of this highly capable operating system. This book is a revision and expansion of a computer science classic. Every chapter has been thoroughly updated with Linux coverage. Linux and the Unix Philosophy falls squarely between the "softer" texts on iterative software design and project management and the "how-to" technical texts. Thus far, no one has come out with a book that addresses this topic, either in the Unix space or the Linux space. Linux and the Unix Philosophy covers the same ground as the first edition, while it also presents bold new ideas about Linux and Open Source. · Concise list of philosophy tenets makes it a handy quick reference · Anecdotal examples personalize the book for the reader · Conversational style makes it easy and joyful to read

Download or read book Software written by Kim W. Tracy and published by Morgan & Claypool. This book was released on 2021-09-20 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Software history has a deep impact on current software designers, computer scientists, and technologists. System constraints imposed in the past and the designs that responded to them are often unknown or poorly understood by students and practitioners, yet modern software systems often include “old” software and “historical” programming techniques. This work looks at software history through specific software areas to develop student-consumable practices, design principles, lessons learned, and trends useful in current and future software design. It also exposes key areas that are widely used in modern software, yet infrequently taught in computing programs. Written as a textbook, this book uses specific cases from the past and present to explore the impact of software trends and techniques. Building on concepts from the history of science and technology, software history examines such areas as fundamentals, operating systems, programming languages, programming environments, networking, and databases. These topics are covered from their earliest beginnings to their modern variants. There are focused case studies on UNIX, APL, SAGE, GNU Emacs, Autoflow, internet protocols, System R, and others. Extensive problems and suggested projects enable readers to deeply delve into the history of software in areas that interest them most.
