Briefly, a boot loader is the first software program that runs when a computer starts. It is responsible for loading and transferring control to an operating system kernel software (such as Linux or GNU Mach). The kernel, in turn, initializes the rest of the operating system (e.g. a GNU system).GNU GRUB is a very powerful boot loader, which can load a wide variety of free operating systems, as well as proprietary operating systems with chain-loading. GRUB is designed to address the complexity of booting a personal computer; both the program and this manual are tightly bound to that computer platform, although porting to other platforms may be addressed in the future.One of the important features in GRUB is flexibility; GRUB understands filesystems and kernel executable formats, so you can load an arbitrary operating system the way you like, without recording the physical position of your kernel on the disk. Thus you can load the kernel just by specifying its file name and the drive and partition where the kernel resides.This manual is available online for free at gnu.org.

This manual attempts to be a full description of Emacs Lisp. This manual presumes considerable familiarity with the use of Emacs for editing. Most of the GNU Emacs text editor is written in the programming language called Emacs Lisp. You can write new code in Emacs Lisp and install it as an extension to the editor. However, Emacs Lisp is more than a mere extension language; it is a full computer programming language in its own right. You can use it as you would any other programming language. Generally speaking, the earlier chapters describe features of Emacs Lisp that have counterparts in many programming languages, and later chapters describe features that are peculiar to Emacs Lisp or relate specically to editing.This is edition 3.1 of the GNU Emacs Lisp Reference Manual, corresponding to Emacs version 25.2.This manual is available online for free at gnu.org.

As an OpenStack cloud end user, you can provision your own resources within the limits setby cloud administrators. The examples in this guide show you how to perform tasks by using the following methods: OpenStack dashboard: Use this web-based graphical interface, code named horizon, to view, create, and manage resources. OpenStack command-line clients: Each core OpenStack project has a command-line client that you can use to run simple commands to view, create, and manage resources in a cloud and automate tasks by using scripts.You can modify these examples for your specific use cases.Many chapters in this manual contain links to additional documentation resources. These include additional documentation that is available on the system, and documentation available on the Internet.This book is available for free in many languages and different formats on the suse.com web site.

The Python/C API manual documents the API used by C and C++ programmers who want to write extension modules or embed Python. It is a companion to extending-index, which describes the general principles of extension writing but does not document the API functions in detail.

Fundamentally, BitBake is a generic task execution engine that allows shell and Python tasks to be run efficiently and in parallel while working within complex inter-task dependency constraints. One of BitBake's main users, OpenEmbedded, takes this core and builds embedded Linux software stacks using a task-oriented approach.This manual provides information on the BitBake tool. The information attempts to be as independent as possible regarding systems that use BitBake, such as OpenEmbedded and the Yocto Project. In some cases, scenarios or examples within the context of a build system are used in the manual to help with understanding. For these cases, the manual clearly states the context. This manual is available online for free at yoctoproject.org. This manual is printed in grayscale.

GCC 8.0 GNU Compiler Collection Internals documents the internals of the GNU compilers, including how to port them to new targets and some information about how to write front ends for new languages. It corresponds to the compilers (GCC) version 8.0.1. The use of the GNU compilers is documented in a separate manual. See Section "Introduction" in Using the GNU Compiler Collection (GCC). This manual is mainly a reference manual rather than a tutorial. It discusses how to contribute to GCC (see Chapter 1 [Contributing], page 3), the characteristics of the machines supported by GCC as hosts and targets (see Chapter 2 [Portability], page 5), how GCC relates to the ABIs on such systems (see Chapter 3 [Interface], page 7), and the characteristics of the languages for which GCC front ends are written (see Chapter 5 [Languages], page 59). It then describes the GCC source tree structure and build system, some of the interfaces to GCC front ends, and how support for a target system is implemented in GCC.

This gentle introduction to discrete mathematics is written for first and second year math majors, especially those who intend to teach. The text began as a set of lecture notes for the discrete mathematics course at the University of Northern Colorado. This course serves both as an introduction to topics in discrete math and as the "introduction to proof" course for math majors. The course is usually taught with a large amount of student inquiry, and this text is written to help facilitate this.Four main topics are covered: counting, sequences, logic, and graph theory. Along the way proofs are introduced, including proofs by contradiction, proofs by induction, and combinatorial proofs. The book contains over 360 exercises, including 230 with solutions and 130 more involved problems suitable for homework. There are also Investigate! activities throughout the text to support active, inquiry based learning.While there are many fine discrete math textbooks available, this text has the following advantages: It is written to be used in an inquiry rich course. It is written to be used in a course for future math teachers. It is open source, with low cost print editions and free electronic editions.Update: as of July 2017, this 2nd edition has been updated, correcting numerous typos and a few mathematical errors. Pagination is almost identical to the earlier printing of the 2nd edition. For a list of changes, see the book's website: http://discretetext.oscarlevin.com

This document describes how the FreeBSD Documentation Project is organized, how to write and submit documentation, and how to effectively use the available tools.This primer shows how to: Identify which parts of FreeBSD are maintained by the FDP. Install the required documentation tools and files. Make changes to the documentation. Submit changes back for review and inclusion in the FreeBSD documentation.This manual is available online for free at freebsd.org. This manual is printed in grayscale.

The FreeBSD Ports Collection is the way almost everyone installs applications ("ports") on FreeBSD. Like everything else about FreeBSD, it is primarily a volunteer effort. It is important to keep this in mind when reading this document.In FreeBSD, anyone may submit a new port, or volunteer to maintain an existing unmaintained port. No special commit privilege is needed.This manual is available online for free at freebsd.org. This manual is printed in grayscale.

Notice: Be sure the version you are buying has the words Full Color Version in the title. Other versions are in grayscale.Hardcover in full-color - ISBN 9781680920895Paperback in full-color - ISBN 9781680920901In 1995, the NASA Systems Engineering Handbook (NASA/SP-6105) was initially published to bring the fundamental concepts and techniques of systems engineering to the National Aeronautics and Space Administration (NASA) personnel in a way that recognized the nature of NASA systems and the NASA environment. Since its initial writing and its revision in 2007 (Rev 1), systems engineering as a discipline at NASA has undergone rapid and continued evolution. This revision (Rev 2) of the Handbook maintains that original philosophy while updating the Agency's systems engineering body of knowledge, providing guidance for insight into current best Agency practices, and maintaining the alignment of the Handbook with the Agency's systems engineering policy. The update of this Handbook continues the methodology of the previous revision: a top-down compatibility with higher-level Agency policy and a bottom-up infusion of guidance from the NASA practitioners in the field. This approach provides the opportunity to obtain best practices from across NASA and bridge the information to the established NASA systems engineering processes and to communicate principles of good practice as well as alternative approaches rather than specify a particular way to accomplish a task. The result embodied in this Handbook is a top-level implementation approach on the practice of systems engineering unique to NASA.
