The purpose of this book is to learn modern C-. The Modern C is C-11, 14, 17 and 20. Organized in themed chapters, this book allows beginners to edsend the language even by reading the chapters in a different order from that proposed by the author. It is the result of several years of work at the ISO standardization committee level, and the following versions, namely C-14, 17 and 20, are only the result of this effort. It should be noted, however, that C-20 is still partially implemented by market compilers, whether It's Microsoft's Visual C, Clang (LLVM) or CCG. On the cloud, everything is Server oriented and Linux reigns supreme. Whether it's multithread or asynchronous programming, with Docker or Azure, it's all about high-availability or hyper-scalabl environments.

Praise for the First Edition: "This outstanding book ... gives the reader robust concepts and implementable knowledge of this environment. Graphical user interface (GUI)-based users and developers do not get short shrift, despite the command-line interface’s (CLI) full-power treatment. ... Every programmer should read the introduction’s Unix/Linux philosophy section. ... This authoritative and exceptionally well-constructed book has my highest recommendation. It will repay careful and recursive study." --Computing Reviews, August 2011 Mastering Modern Linux, Second Edition retains much of the good material from the previous edition, with extensive updates and new topics added. The book provides a comprehensive and up-to-date guide to Linux concepts, usage, and programming. The text helps the reader master Linux with a well-selected set of topics, and encourages hands-on practice. The first part of the textbook covers interactive use of Linux via the Graphical User Interface (GUI) and the Command-Line Interface (CLI), including comprehensive treatment of the Gnome desktop and the Bash Shell. Using different apps, commands and filters, building pipelines, and matching patterns with regular expressions are major focuses. Next comes Bash scripting, file system structure, organization, and usage. The following chapters present networking, the Internet and the Web, data encryption, basic system admin, as well as Web hosting. The Linux Apache MySQL/MariaDB PHP (LAMP) Web hosting combination is also presented in depth. In the last part of the book, attention is turned to C-level programming. Topics covered include the C compiler, preprocessor, debugger, I/O, file manipulation, process control, inter-process communication, and networking. The book includes many examples and complete programs ready to download and run. A summary and exercises of varying degrees of difficulty can be found at the end of each chapter. A companion website (http://mml.sofpower.com) provides appendices, information updates, an example code package, and other resources for instructors, as well as students.

This book provides a comprehensive introduction for those new to Linux device driver development and will have you up and running with writing misc class character device driver code (on the 5.4 LTS Linux kernel) in next to no time. You'll begin by learning how to write a simple and complete misc class character driver before interfacing your driver with user-mode processes via procfs, sysfs, debugfs, netlink sockets, and ioctl. You'll then find out how to work with hardware I/O memory. The book covers working with hardware interrupts in depth and helps you understand interrupt request (IRQ) allocation, threaded IRQ handlers, tasklets, and softirqs. You'll also explore the practical usage of useful kernel mechanisms, setting up delays, timers, kernel threads, and workqueues. Finally, you'll discover how to deal with the complexity of kernel synchronization with locking technologies (mutexes, spinlocks, and atomic/refcount operators), including more advanced topics such as cache effects, a primer on lock-free techniques, deadlock avoidance (with lockdep), and kernel lock debugging techniques. By the end of this Linux kernel book, you'll have learned the fundamentals of writing Linux character device driver code for real-world projects and products.

This is the story of a German-born executive, JK, who immigrated to the United States to aid Bill Gates and Steve Ballmer, Microsofts top honchos to build a commanding software empire. He led Microsofts OEM division that was responsible for sales to PC manufacturers, and drove the deals that made Microsoft Windows the worlds dominating operating system. Find out how much resolve, fortitude, and perseverance were needed to make that part of the PC revolution come true; what strategies were employed to win the Internet browser war; how IBM was beaten; what drove Apple to the brink of disaster; and how shady politicians and hapless competitors eventually goaded the Feds to ensnare Microsoft in a web of antitrust accusations. Peek behind the curtain and be the first-ever outsider to glimpse into Microsofts power nexus. Understand how Microsofts nearly mystical marketing shrewdness and tech prowess are intensely propelled by paranoia and fear of missing the next computing paradigm shift. The press labeled JK Bill Gatess enforcer. No wonder he was called upon as a pivotal antitrust trial witness to defend what loathing competitors labeled Microsofts evil empire. Follow what experts believe was the most protracted, and fierce trial of the century. Relive the courtroom drama, and read the authors critical analysis of the judicial proceedings and their aftermaths. Losing that trial partially started Microsofts demise, and power struggles from within quickened it. Get to know the real forces that altered Microsofts resolve-and fortitude-dominated leadership style. Find out if Windows 8 could be an inflection point, conjuring enough magic to ring in a renaissance and attract the Facebook generation to a born-again modern Microsoft.
