Book Description

Cross-platform development is a kind of holy grail, and Trolltech’s Qt toolkit may well be the most promising solution yet to this development challenge. Qt is widely used for the development of GUI applications as well as console tools and servers, and it’s especially appealing to programmers who need to write cross-platform applications to run on Linux/Unix, Mac, and Windows machines without having to rewrite for each platform.

The Book of Qt 4 offers an in-depth explanation of Qt 4 that goes beyond the common focus on C++ programming. Author Daniel Molkentin uses practical examples to explain features like the signal/slot concept and the event system, as he guides you through developing applications with and without Qt’s graphical GUI builder, Qt Designer. And as a core KDE developer, Molkentin’s head is full of real-world problems and solutions that he peppers liberally throughout The Book of Qt 4, making it a resource that you’ll consult time and again. You’ll find coverage of:

• Tools for creating dialogs
• GUI design with the Qt Designer
• Widget layout and dialog construction
• Data visualization using Qt’s model/view concept
• The QtSql module and the graphics library Arthur
• File handling, XML, processes, and network connections
• Databases and threading
• Event handling and using drag and drop Download Now »

Book Description

You’ve experienced the shiny, point-and-click surface of your Linux computer—now dive below and explore its depths with the power of the command line.

The Linux Command Line takes you from your very first terminal keystrokes to writing full programs in Bash, the most popular Linux shell. Along the way you’ll learn the timeless skills handed down by generations of gray-bearded, mouse-shunning gurus: file navigation, environment configuration, command chaining, pattern matching with regular expressions, and more.

In addition to that practical knowledge, author William Shotts reveals the philosophy behind these tools and the rich heritage that your desktop Linux machine has inherited from Unix supercomputers of yore.

As you make your way through the book’s short, easily-digestible chapters, you’ll learn how to:

• Create and delete files, directories, and symlinks
• Administer your system, including networking, package installation, and process management
• Use standard input and output, redirection, and pipelines
• Edit files with Vi, the world’s most popular text editor
• Write shell scripts to automate common or boring tasks
• Slice and dice text files with cut, paste, grep, patch, and sed

Once you overcome your initial “shell shock,” you’ll find Download Now »

Book Description

OS X and iOS Kernel Programming combines essential operating system and kernel architecture knowledge with a highly practical approach that will help you write effective kernel-level code. You’ll learn fundamental concepts such as memory management and thread synchronization, as well as the I/O Kit framework. You’ll also learn how to write your own kernel-level extensions, such as device drivers for USB and Thunderbolt devices, including networking, storage and audio drivers.

OS X and iOS Kernel Programming provides an incisive and complete introduction to the XNU kernel, which runs iPhones, iPads, iPods, and Mac OS X servers and clients. Then, you’ll expand your horizons to examine Mac OS X and iOS system architecture. Understanding Apple’s operating systems will allow you to write efficient device drivers, such as those covered in the book, using I/O Kit.

With OS X and iOS Kernel Programming, you’ll:

• Discover classical kernel architecture topics such as memory management and thread synchronization
• Become well-versed in the intricacies of the kernel development process by applying kernel debugging and profiling tools
• Learn how to deploy your kernel-level projects and how to successfully package them
• Write code that interacts with hardware devices
• Examine easy to understand example code that can also be used in your own projects Download Now »
