在微软垄断下有一件东西永远它永远不会给你――真正的自由。也正是因为这个原因，不少先锋人物站出来反抗微软帝国，并努力建立一种新的操作系统――没有人为的限制，任何人都可以自由地使用。
为了记录这些人的艰苦历程，J.T.S. Moore拍摄了全新的记录片――REVOLUTON OS，向公众介绍这些建立Linux操作系统，奋起反抗垄断的斗士的人生经历。
现在微软已经明显感到了来自Linux的压力。微软的首席执行官去年6月公开表示："Linux 是一种癌症！"。但这丝毫不能影响Linux发展的步伐。
操作系统革命S中记录了Linux的创建人Linus Torvalds以及Richard Stallman, Bruce Perens, Eric Raymond, Brian Behlendorf, Michael Tiemann, Larry Augustin, Frank Hecker, Rob Malda等人的生活经历或者采访记录。

The accelerating deployment of large-scale web, cloud, Big Data, and virtualized computing systems has introduced serious new challenges in performance optimization. Until now, however, little reliable, practical information has been available to IT professionals who are responsible for running these systems efficiently and cost-effectively.
Systems Performance: Enterprise and the Cloud is the solution. Internationally renowned performance optimization expert Brendan Gregg brings together state-of-the-art techniques and tools for analysis and tuning of large-scale web/cloud computing environments.
Gregg focuses on Linux/Unix/Solaris performance issues, while offering proven methodologies and discussing key issues that apply to all enterprise operating systems. Coverage includes:
Modern performance analysis and capacity planning, including key issues such as latency and dynamic tracing
New performance and reliability challenges associated with cloud computing
Methodology, concepts, terminology, tools, and metrics
Key tradeoffs, including problems of load vs. architecture
Tuning operating systems, CPUs, memory, file systems, disks, networks, and busses
Tuning virtualized systems
Programming language issues related to performance — including application profiling for C, C++, Java, and node.js
Benchmarking strategies and pitfalls, including custom microbenchmarking

本书内容基于Linux4.x内核，主要选取了Linux内核中比较基本和常用的内存管理、进程管理、并发与同步，以及中断管理这4个内核模块进行讲述。全书共分为6章，依次介绍了ARM体系结构、Linux内存管理、进程调度管理、并发与同步、中断管理、内核调试技巧等内容。本书的每节内容都是一个Linux内核的话题或者技术点，读者可以根据每小节前的问题进行思考，进而围绕问题进行内核源代码的分析。
本书内容丰富，讲解清晰透彻，不仅适合有一定Linux相关基础的人员，包括从事与Linux相关的开发人员、操作系统的研究人员、嵌入式开发人员及Android底层开发人员等学习和使用，而且适合作为对Linux感兴趣的程序员的学习用书，也可以作为大专院校相关专业师生的学习用书和培训学校的教材。

Device drivers literally drive everything you're interested in--disks, monitors, keyboards, modems--everything outside the computer chip and memory. And writing device drivers is one of the few areas of programming for the Linux operating system that calls for unique, Linux-specific knowledge. For years now, programmers have relied on the classic Linux Device Drivers from O'Reilly to master this critical subject. Now in its third edition, this bestselling guide provides all the information you'll need to write drivers for a wide range of devices. Over the years the book has helped countless programmers learn: * how to support computer peripherals under the Linux operating system * how to develop and write software for new hardware under Linux * the basics of Linux operation even if they are not expecting to write a driver The new edition of Linux Device Drivers is better than ever. The book covers all the significant changes to Version 2.6 of the Linux kernel, which simplifies many activities, and contains subtle new features that can make a driver both more efficient and more flexible. Readers will find new chapters on important types of drivers not covered previously, such as consoles, USB drivers, and more. Best of all, you don't have to be a kernel hacker to understand and enjoy this book. All you need is an understanding of the C programming language and some background in Unix system calls. And for maximum ease-of-use, the book uses full-featured examples that you can compile and run without special hardware. Today Linux holds fast as the most rapidly growing segment of the computer market and continues to win over enthusiastic adherents in many application areas. With this increasing support, Linux is now absolutely mainstream, and viewed as a solid platform for embedded systems. If you're writing device drivers, you'll want this book. In fact, you'll wonder how drivers are ever written without it.

The third edition of the authoritative, practical introduction to the Linux kernel for programmers who want to better understand the Linux kernel and write and develop kernel code. Authored by a well-known member of the Linux kernel development team, with a reputation for a highly readable and focused writing style, this edition has been thoroughly updated and includes improved coverage of all the major subsystems and features of the latest version of the Linux 2.6.xx kernel.
Linux Kernel Development details the design and implementation of the Linux kernel, presenting the content in a manner that is beneficial to those writing and developing kernel code. While the book discusses topics that are theoretical, it does so with the goal of assisting programmers so they better understand the topics and become more efficient and productive in their coding.
The book discusses the major subsystems and features of the Linux kernel, including design and implementation, their purpose and goals, and their interfaces. Important computer science and operating system design details are also addressed. The book covers the Linux kernel from both angles -- theoretical and applied -- which should appeal to both types of readers.
The author, a core kernel developer, shares valuable knowledge and experience on the very latest Linux kernel.
Specific topics covered will include: all the important algorithms, relevant subsystems, process management, scheduling, time management and timers, system call interface, memory addressing, memory management, paging strategies, caching layers, VFS, kernel synchronization, and signals.
An authoritative, practical guide that helps programmers better understand the Linux kernel, and to write and develop kernel code.
* Authored by core Linux kernel developers.
* In-depth coverage of all the major subsystems and features of the new Linux 2.6 kernel.
* Targeted audience includes programmers interested in gaining relevant and timely information so they may further their kernel development skills.
