  • UNIX Version 7 Volume 1
    UNIXTM TIME-SHARING SYSTEM: UNIX PROGRAMMER'S MANUAL Seventh Edition, Volume 1 January, 1979 Bell Telephone Laboratories, Incorporated Murray Hill, New Jersey PREFACE Although this Seventh Edition no longer bears their byline, Ken Thompson and Dennis Ritchie remain the fathers and preceptors of the UNIX² time-sharing system. Many of the improvements here described bear their mark. Among many, many other people who have contributed to the further ¯owering of UNIX, we wish especially to acknowledge the contributions of A. V. Aho, S. R. Bourne, L. L. Cherry, G. L. Chesson, S. I. Feldman, C. B. Haley, R. C. Haight, S. C. Johnson, M. E. Lesk, T. L. Lyon, L. E. McMahon, R. Morris, R. Muha, D. A. Nowitz, L. Wehr, and P. J. Weinberger. We appreciate also the effective advice and criticism of T. A. Dolotta, A. G. Fraser, J. F. Maranzano, and J. R. Mashey; and we remember the important work of the late Joseph F. Ossanna. B. W. Kernighan M. D. McIlroy __________________ ²UNIX is a Trademark of Bell Laboratories. INTRODUCTION TO VOLUME 1 This volume gives descriptions of the publicly available features of the UNIX² system. It does not attempt to provide perspective or tutorial information upon the UNIX operating system, its facilities, or its implementation. Various documents on those topics are contained in Volume 2. In particular, for an overview see `The UNIX Time-Sharing System' by Ritchie and Thompson; for a tutorial see `UNIX for Beginners' by Kernighan. Within the area it surveys, this volume attempts to be timely, complete and concise. Where the latter two objectives con¯ict, the obvious is often left unsaid in favor of brevity.

  • An Introduction to the X Window System Introduction to X's Anatomy
    An Introduction to the X Window System Robert Lupton This is a limited and partisan introduction to ‘The X Window System’, which is widely but improperly known as X-windows, specifically to version 11 (‘X11’). The intention of the X-project has been to provide ‘tools not rules’, which allows their basic system to appear in a very large number of confusing guises. This document assumes that you are using the configuration that I set up at Peyton Hall † There are helpful manual entries under X and Xserver, as well as for individual utilities such as xterm. You may need to add /usr/princeton/X11/man to your MANPATH to read the X manpages. This is the first draft of this document, so I’d be very grateful for any comments or criticisms. Introduction to X’s Anatomy X consists of three parts: The server The part that knows about the hardware and how to draw lines and write characters. The Clients Such things as terminal emulators, dvi previewers, and clocks and The Window Manager A programme which handles negotiations between the different clients as they fight for screen space, colours, and sunlight. Another fundamental X-concept is that of resources, which is how X describes any- thing that a client might want to specify; common examples would be fonts, colours (both foreground and background), and position on the screen. Keys X can, and usually does, use a number of special keys. You are familiar with the way that <shift>a and <ctrl>a are different from a; in X this sensitivity extends to things like mouse buttons that you might not normally think of as case-sensitive.

  • Solaris 10 End of Life
    Solaris 10 end of life Continue Oracle Solaris 10 has had an amazing OS update, including ground features such as zones (Solaris containers), FSS, Services, Dynamic Tracking (against live production operating systems without impact), and logical domains. These features have been imitated in the market (imitation is the best form of flattery!) like all good things, they have to come to an end. Sun Microsystems was acquired by Oracle and eventually, the largest OS known to the industry, needs to be updated. Oracle has set a retirement date of January 2021. Oracle indicated that Solaris 10 systems would need to raise support costs. Oracle has never provided migratory tools to facilitate migration from Solaris 10 to Solaris 11, so migration to Solaris has been slow. In September 2019, Oracle decided that extended support for Solaris 10 without an additional financial penalty would be delayed until 2024! Well its March 1 is just a reminder that Oracle Solaris 10 is getting the end of life regarding support if you accept extended support from Oracle. Combined with the fact gdpR should take effect on May 25, 2018 you want to make sure that you are either upgraded to Solaris 11.3 or have taken extended support to obtain any patches for security issues.

  • A Survey of Distributed File Systems
    A Survey of Distributed File Systems M. Satyanarayanan Department of Computer Science Carnegie Mellon University February 1989 Abstract Abstract This paper is a survey of the current state of the art in the design and implementation of distributed file systems. It consists of four major parts: an overview of background material, case studies of a number of contemporary file systems, identification of key design techniques, and an examination of current research issues. The systems surveyed are Sun NFS, Apollo Domain, Andrew, IBM AIX DS, AT&T RFS, and Sprite. The coverage of background material includes a taxonomy of file system issues, a brief history of distributed file systems, and a summary of empirical research on file properties. A comprehensive bibliography forms an important of the paper. Copyright (C) 1988,1989 M. Satyanarayanan The author was supported in the writing of this paper by the National Science Foundation (Contract No. CCR-8657907), Defense Advanced Research Projects Agency (Order No. 4976, Contract F33615-84-K-1520) and the IBM Corporation (Faculty Development Award). The views and conclusions in this document are those of the author and do not represent the official policies of the funding agencies or Carnegie Mellon University. 1 1. Introduction The sharing of data in distributed systems is already common and will become pervasive as these systems grow in scale and importance. Each user in a distributed system is potentially a creator as well as a consumer of data. A user may wish to make his actions contingent upon information from a remote site, or may wish to update remote information.

  • Chapter 1 – 15 Essay Question Review
    Chapter 1 – 15 Essay Question Review Chapter 1 1. Explain why an operating system can be viewed as a resource allocator. Ans: A computer system has many resources that may be required to solve a problem: CPU time, memory space, file-storage space, I/O devices, and so on. The operating system acts as the manager of these resources. Facing numerous and possibly conflicting requests for resources, the operating system must decide how to allocate them to specific programs and users so that it can operate the computer system efficiently and fairly. Feedback: 1.1.2 2. Explain the purpose of an interrupt vector. Ans: The interrupt vector is merely a table of pointers to specific interrupt-handling routines. Because there are a fixed number of interrupts, this table allows for more efficient handling of the interrupts than with a general-purpose, interrupt-processing routine. Feedback: 1.2.1 3. What is a bootstrap program, and where is it stored? Ans: A bootstrap program is the initial program that the computer runs when it is powered up or rebooted. It initializes all aspects of the system, from CPU registers to device controllers to memory contents. Typically, it is stored in read-only memory (ROM) or electrically erasable programmable read-only memory (EEPROM), known by the general term firmware, within the computer hardware. Feedback: 1.2.1 4. What role do device controllers and device drivers play in a computer system? Ans: A general-purpose computer system consists of CPUs and multiple device controllers that are connected through a common bus.
