    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.

    Based on more than forty interviews with Steve Jobs conducted over two years--as well as interviews with more than 100 family members, friends, adversaries, competitors, and colleagues--Walter Isaacson has written a riveting story of the roller-coaster life and searingly intense personality of a creative entrepreneur whose passion for perfection and ferocious drive revolutionized six industries: personal computers, animated movies, music, phones, tablet computing, and digital publishing. Isaacson's portrait touched millions of readers. At a time when America is seeking ways to sustain its innovative edge, Jobs stands as the ultimate icon of inventiveness and applied imagination. He knew that the best way to create value in the twenty-first century was to connect creativity with technology. He built a company where leaps of the imagination were combined with remarkable feats of engineering. Although Jobs cooperated with the author, he asked for no control over what was written. He put nothing off-limits. He encouraged the people he knew to speak honestly. He himself spoke candidly about the people he worked with and competed against. His friends, foes, and colleagues offer an unvarnished view of the passions, perfectionism, obsessions, artistry, devilry, and compulsion for control that shaped his approach to business and the innovative products that resulted. His tale is instructive and cautionary, filled with lessons about innovation, character, leadership, and values. Steve Jobs is the inspiration for the movie of the same name starring Michael Fassbender, Kate Winslet, Seth Rogen, and Jeff Daniels, directed by Danny Boyle with a screenplay by Aaron Sorkin.

    Building upon that record and the recollections of other F-4G Wild Weasel aircrew, the authors show a slice of what life and war was like during that time. The pawns in the game, the ones that had to actually do the fighting and dying were the hundreds of thousands of men and women who left their homes and families to live for seemingly endless months in the vast, trackless desert while the world stage-play unfolded. To them, the war was deeply personal. At times, the war was scary; at other times, it was funny as hell. Usually, if you survive the former, it turns into the latter.

    His claim that “harnessing the forces of nature was the only worthwhile scientific endeavor" both impressed and enraged the scientific community. Eventually, his peers could no longer dismiss his eccentricities and began to view him as a crackpot — a potentially dangerous one. Although Tesla’s work was a major factor in the success of the second Industrial Revolution, he died alone, impoverished, and largely shunned by the scientific community that once hailed him a genius. Beset by visions, without a wife or children, Nikola Tesla’s brilliant mind changed the world, even though at the time of his death he passed unnoticed into obscurity. Some of the topics covered in this book include: Childhood Education and Early Career Patents and Politics The Eccentric Genius Tesla’s Coil and the Niagara Contract Influential Friends and the Lure of Flight The Wardenclyffe Tower 1914 and Beyond And much more!

    It was not until moments before landing that anything went wrong. Coming in to Heathrow Airport, the plane suffered inexplicable loss of power to both engines, and it was suddenly likely that the plane would plough into a built-up area outside the airport, with the loss of all lives on board. Peter tells us in graphic detail his thoughts and actions when he managed to help save the plane at the last moment thanks to a flash of inspiration that led him to change the position of the wing flaps, which appeared to gain the vehicle enough precious time to make it over the perimeter fence and land on the grass, short of the runway. For both Maria and Peter, their lives following the crash have resulted in experiences that they never would have expected to have happened. There isn't a handbook with rules to follow after a crash so the subsequent aftermath was laced with events that could have been handled better from all sides, which lead to Maria and Peter having to find strength inside them that they had never needed before. A little more than a year later, they have used these strengths to begin a new chapter in their lives; starting with leaving British Airways and celebrating a second chance to enjoy life.But there are still nights when they find themselves awake, crying about what could have happened on that fateful day.

    For years, experts have argued over the tiny details of exactly how they do what they do, and how their various components interact. What's undeniable is that, far more than being just a loudness booster the unique combination of tubes, capacitors, resistors, and transformers in these amps can contribute enormously to the quality of sound derived from any electric guitar. In this thorough and authoritative book, Dave Hunter cuts through the marketing hyperbole, and the blind faith, and supplies all the information you need to choose the right amp, and get the best from it. The book also features exclusively conducted, in-depth interviews with leading figures in the tube amp-building world - including Ken Fischer, Mark Sampson, and Michael Zaite - and even provides full instructions on how to construct your own high-quality tube guitar amp from scratch.
