  the official ubuntu server book 2nd edition: Ubuntu and the Reconstitution of Community James Ogude, 2019-05-16 Ubuntu is premised on the ethical belief that an individual's humanity is fostered in a network of human relationships: I am because you are; we are because you are. The essays in this lively volume elevate the debate about ubuntu beyond the buzzword it has become, especially within South African religious and political contexts. The seasoned scholars and younger voices gathered here grapple with a range of challenges that ubuntu puts forward. They break down its history and analyze its intellectual surroundings in African philosophical traditions, European modernism, religious contexts, and human rights discourses. The discussion embraces questions about what it means to be human and to be a part of a community, giving attention to moments of loss and fragmentation in postcolonial modernity, to come to a more meaningful definition of belonging in a globalizing world. Taken together, these essays offer a rich understanding of ubuntu in all of its complexity and reflect on a value system rooted in the everyday practices of ordinary people in their daily encounters with churches, schools, and other social institutions.

Linux Application Development is divided into four parts. Part 1 introduces you to Linux(the operating system, licenses, and documentation. Part 2 covers the most important aspects of the development environment(the compilers, linker, loader, and debugging tools. Part 3-the heart of the book-describes the interface to the kernel and to the core system libraries, including discussion of the process model, file handling, directory operations, signal processing (including the Linux signal API), job control, the POSIX(termios interface, sockets, and the Linux console. Part 4 describes important development libraries with interfaces more independent of the kernel. The source code from the book is freely available at http://www.awl.com/cseng/books/lad.

  the official ubuntu server book 2nd edition: Understanding the Linux Kernel Daniel Pierre Bovet, Marco Cesati, 2002 To thoroughly understand what makes Linux tick and why it's so efficient, you need to delve deep into the heart of the operating system--into the Linux kernel itself. The kernel is Linux--in the case of the Linux operating system, it's the only bit of software to which the term Linux applies. The kernel handles all the requests or completed I/O operations and determines which programs will share its processing time, and in what order. Responsible for the sophisticated memory management of the whole system, the Linux kernel is the force behind the legendary Linux efficiency. The new edition of Understanding the Linux Kernel takes you on a guided tour through the most significant data structures, many algorithms, and programming tricks used in the kernel. Probing beyond the superficial features, the authors offer valuable insights to people who want to know how things really work inside their machine. Relevant segments of code are dissected and discussed line by line. The book covers more than just the functioning of the code, it explains the theoretical underpinnings for why Linux does things the way it does. The new edition of the book has been updated to cover version 2.4 of the kernel, which is quite different from version 2.2: the virtual memory system is entirely new, support for multiprocessor systems is improved, and whole new classes of hardware devices have been added. The authors explore each new feature in detail. Other topics in the book include: Memory management including file buffering, process swapping, and Direct memory Access (DMA) The Virtual Filesystem and the Second Extended Filesystem Process creation and scheduling Signals, interrupts, and the essential interfaces to device drivers Timing Synchronization in the kernel Interprocess Communication (IPC) Program execution Understanding the Linux Kernel, Second Edition will acquaint you with all the inner workings of Linux, but is more than just an academic exercise. You'll learn what conditions bring out Linux's best performance, and you'll see how it meets the challenge of providing good system response during process scheduling, file access, and memory management in a wide variety of environments. If knowledge is power, then this book will help you make the most of your Linux system.

This book also helps you identify and fix the “unknown unknowns” of complex performance: bottlenecks that emerge from elements and interactions you were not aware of. The text concludes with a detailed case study, showing how a real cloud customer issue was analyzed from start to finish. Coverage includes • Modern performance analysis and tuning: terminology, concepts, models, methods, and techniques • Dynamic tracing techniques and tools, including examples of DTrace, SystemTap, and perf • Kernel internals: uncovering what the OS is doing • Using system observability tools, interfaces, and frameworks • Understanding and monitoring application performance • Optimizing CPUs: processors, cores, hardware threads, caches, interconnects, and kernel scheduling • Memory optimization: virtual memory, paging, swapping, memory architectures, busses, address spaces, and allocators • File system I/O, including caching • Storage devices/controllers, disk I/O workloads, RAID, and kernel I/O • Network-related performance issues: protocols, sockets, interfaces, and physical connections • Performance implications of OS and hardware-based virtualization, and new issues encountered with cloud computing • Benchmarking: getting accurate results and avoiding common mistakes This guide is indispensable for anyone who operates enterprise or cloud environments: system, network, database, and web admins; developers; and other professionals. For students and others new to optimization, it also provides exercises reflecting Gregg’s extensive instructional experience.
