    Understanding the design, implementation, and workings of Mac OS X requires examination of several technologies that differ in their age, origins, philosophies, and roles. Mac OS X Internals: A Systems Approach is the first book that dissects the internals of the system, presenting a detailed picture that grows incrementally as you read. For example, you will learn the roles of the firmware, the bootloader, the Mach and BSD kernel components (including the process, virtual memory, IPC, and file system layers), the object-oriented I/O Kit driver framework, user libraries, and other core pieces of software. You will learn how these pieces connect and work internally, where they originated, and how they evolved. The book also covers several key areas of the Intel-based Macintosh computers.A solid understanding of system internals is immensely useful in design, development, and debugging for programmers of various skill levels. System programmers can use the book as a reference and to construct a better picture of how the core system works. Application programmers can gain a deeper understanding of how their applications interact with the system. System administrators and power users can use the book to harness the power of the rich environment offered by Mac OS X. Finally, members of the Windows, Linux, BSD, and other Unix communities will find the book valuable in comparing and contrasting Mac OS X with their respective systems. Mac OS X Internals focuses on the technical aspects of OS X and is so full of extremely useful information and programming examples that it will definitely become a mandatory tool for every Mac OS X programmer.

    A significant amount of research and subsequent progress has been made in these fields. The advancement made in the understanding the underlying physics has enabled the development of several interesting applications. In these applications, semiconductors like Silicon, Gallium Arsenide exploit the charge of the electron and ferromagnetic materials make use of the spin of an electron. If these two interesting properties of semiconductors and ferromagnets can be used in conjunction, several exciting applications can be envisaged.;This new domain where such materials are being researched has been termed as Diluted Magnetic Semiconductors (DMS). The biggest challenge in the development of these materials was to put the idea into practical reality. The invention of a novel low-temperature epitaxial process in the late 1980's enabled the realization of the DMS concept and ushered a renewed interest throughout the scientific community.;Gallium Manganese Arsenide has been a test bed for understanding the underlying science behind DMS. A major challenge in the practical utility of DMS materials has been the very low Curie temperatures. The present thesis work discusses the experiments conducted at the Nanofabrication facility and the magneto-transport laboratory at the University of Arkansas. GaMnAs samples were grown using the LT-MBE process, and the samples were characterized using X-Ray analysis. A deeper insight into the magnetic and transport properties of these materials was acquired through low temperature SQUID and Hall Effect measurements.

    With its simple commands, flags, and parameters, a well-formed command-line application is the quickest way to automate a backup, a build, or a deployment and simplify your life. As Ruby pro David Copeland explains, writing a command-line application that is self-documenting, robust, adaptable and forever useful is easier than you might think. Ruby is particularly suited to this task, since it combines high-level abstractions with "close to the metal" system interaction wrapped up in a concise, readable syntax. Moreover, Ruby has the support of a rich ecosystem of open-source tools and libraries. Ten insightful chapters each explain and demonstrate a command-line best practice. You'll see how to use these tools to elevate the lowliest automation script to a maintainable, polished application. You'll learn how to use free, open source parsers to create user-friendly command-line interfaces as well as command suites. You'll see how to use defaults to keep options simple for everyday users, while giving advanced users options for more complex tasks. There's no reason a command-line application should lack documentation, whether it's part of a help command or a man page; you'll find out when and how to use both. Your journey from command-line novice to pro ends with a look at valuable approaches to testing your apps, and includes some fun techniques for outside-the-box, colorful interfaces that will delight your users. With Ruby, the command line is not dead. Long live the command line.What You Need: All you'll need is Ruby, and the ability to install a few gems along the way. Examples written for Ruby 1.9.2, but 1.8.7 should work just as well.

    Sick of the weather, perennial colds and their increasingly routine lifestyle, they’d all been getting restless. Finally, Guy and Juliet broke in spectacular style – they re-mortgaged their house and bought a yacht. Her name was Forever.The plan? To pick up Forever from her mooring in the Leeward Antilles off the coast of Venezuela, and sail around the West Indies before crossing the Atlantic back to Scotland. This was despite the fact that Guy, skipper of the expedition, had almost no sailing experience.Travelling around the lush tropical islands of the Caribbean and up the waterways of America, the family had countless sublime moments as they discovered the freedoms of sailing – anchoring in deserted bays, night passages under star-studded skies, and entering New York by water, greeted by the Statue of Liberty. But there were also testing times as they grappled with seasickness and bad weather, coping with young children at sea and learning to run a large, complex boat. Far from being the idyllic escape they’d envisaged, the journey forced Guy and Juliet to draw on reserves of courage and endurance they never knew they had.Wry, funny and buccaneering, this is a compelling tale of bravery and endeavour, out on the open sea.
