Book Description
As our daily lives and corporate well-being become more dependent upon computers, system reliability grows increasingly important. No longer are frequent system outages acceptable. In many cases, failure intervals must now be measured in centuries. Even current fault-tolerant computing systems will fail once every five or ten years. This book is the first in a three-part series on active/active systems. It describes techniques that can be used today for extending system failure times from years to centuries, often at little or no additional cost. The techniques described include splitting a large system into smaller, cooperating independent nodes. Copies of the application's database are distributed across the nodes. It is shown that these techniques significantly reduce the number of system failure modes and increase the level of sparing. As a result, the loss of a single node's capacity occurs far less frequently than the loss of all capacity when the equivalent monolithic system fails. Furthermore, the loss of more than one node's worth of capacity is almost never. Central to these techniques is the requirement that all database copies that are distributed across the network must be kept in synchronism. Several methods available today for maintaining synchronism are described. They include asynchronous data replication, synchronous data replication, and network transactions.

Book Description
"To err is human, to forgive divine," goes the familiar saying. If you have ever aspired to realize the divine within you, you need look no further - within the pages of this powerful book you will find the means to master The Magic of Forgiveness as Dada J.P. Vaswani describes it. What is forgiveness? Why should we forgive? How can forgiveness empower us, heal us, help us to bury the dead past and begin our lives anew? Answers to these and other burning questions are offered here. Dada J.P. Vaswani, whose knowledge of human nature is profound, but, at the same time, compassionate and non-judgemental, teaches us how to apologize with grace; how to forgive with generosity; how to restore damaged relationships; how to overcome resentment and bitterness; how to forgive ourselves when the need arises; and above all, how to forget after we have forgiven someone. It has been said, "We win by tenderness; we conquer by forgiveness." In this book, Dada J.P. Vaswani shows us how we may conquer ourselves - and the hearts of others - by The Magic of Forgiveness!

Book Description
The Bhagavad Gita is a world-scripture with a world message, It is not meant for India alone: it is a "Bible of Humanity". The Gita has an answer to the problems and perplexities of the modern world. The problems of social, national and international reconstruction will not be solved without an appreciation of those deeper values of life which, the Gita shows, are the very structure of Reality. A new Indian nation, a new social order, a new civilisation must be built on the essential teachings of the Gita. The wisdom of the Gita is the hope of a new humanity Sadhu Vaswani, who was regarded by many as an "embodiment of the Gita", a "living Gita", and who was equally at home in the Eastern and Western traditions of thought, gives us in this book the teaching of the Gita in simple words. In the Bhagavad Gita, simplicity is combined with wisdom. The essential teaching of the Bhagavad Gita has been overlaid by controversies which scholars and theologians may understand but not lovers of the simple life. In the present volume, the author has simplified the message of the Bhagavad Gita and related it to the experience and aspirations of the common man. "To the vast majority of men", he says, "life seems to be a meaningless muddle. Not many seem to realise that life, at its noblest, is a yatra, a piligrimage to God: the Infinite is our true Home."

Book Description
This book takes the reader through a journey of how fear of loss progressively creates barriers and bureaucracy that inevitably cause companies to fail -- and what leaders need to do to overcome these seemingly impenetrable walls. The greatest threat to an organization's success is not always the competition. Often, it is what a company does to itself. Because of fear, companies become plagued with barriers and bureaucracy that limit success, crush employees, and infuse frustration and a sense of futility across the enterprise. It starts with a narrowing of focus, which leads to the first level of bureaucracy: parochialism. Parochialism exists when managers and departments begin to view the world through the filter of their own little silo and build walls made of rules and policies to protect their turf. As businesses grow and become more complex, the second level of bureaucracy is reached: territorialism. While parochialism is about protecting a department from outsiders, territorialism is about controlling those inside the silo. The third and final level of bureaucracy is empire building, which is a response to perceived threats to a department's ability to be self-sufficient. These barriers cost organizations a fortune in inefficiency, turnover, waste, and demoralization. Tearing down these barriers is difficult, but it can be done. Parochialism can be eliminated by resetting rules and policies and refocusing on the ultimate mission of the organization. Territorialism can be eliminated by creating true empowerment, along with appropriate levels of accountability. Empire building can be addressed through shared goals and a set of guiding principles that help act as a referee in decision making. But that's not enough. Managers must also create a culture of courage to enable employees to take advantage of these new freedoms and accountabilities. Courage killers must be rooted out and dealt with swiftly and strongly. Finally, leaders must refocus on mission success rather than just checking off their part of the process, manage reference points, and engage employees. By doing all these things, an organization can become fearless and unstoppable.

Book Description
IT WAS ONLY A MATTER OF TIME.... Once widely considered an impossibility--the stuff of science fiction novels--time travel may finally be achieved in the twenty-first century. In Breaking the Time Barrier, bestselling author Jenny Randles reveals the nature of recent, breakthrough experiments that are turning this fantasy into reality. The race to build the first time machine is a fascinating saga that began about a century ago, when scientists such as Marconi and Edison and Einstein carried out research aimed at producing a working time machine. Today, physicists are conducting remarkable experiments that involve slowing the passage of information, freezing light, and breaking the speed of light--and thus the time barrier. In the 1960s we had the "space race." Today, there is a "time race" involving an underground community of working scientists who are increasingly convinced that a time machine of some sort is finally possible. Here, Randles explores the often riveting motives of the people involved in this quest (including a host of sincere, if sometimes misguided amateurs), the consequences for society should time travel become a part of everyday life, and what evidence might indicate that it has already become reality. For, if time travel is going to happen--and some Russian scientists already claim to have achieved it in a lab--then its effects may already be apparent.

Book Description
Build Extraordinary Trust and Lead Your Team to a Higher Plane For former US Air Force Thunderbirds' commander and demonstration leader JV Venable, inspiring teamwork was literally a matter of life and death. On maneuvers like the one pictured on the cover, the distance between jets was just eighteen inches. Closing the gaps to sustain that kind of separation requires the highest levels of trust. On the ground or in the air, from line supervisor to CEO, we all face the same challenge. Our job is to entice those we lead to close the gaps that slow the whole team down—gaps in commitment, loyalty, and trust. Every bit of closure requires your people to let go of biases and mental safeguards that hold them back. The process the Thunderbirds use to break that barrier and craft the highest levels of trust on a team with an annual turnover of 50 percent is nothing short of phenomenal. That process is packaged here with tips and compelling stories that will help you build the team of a lifetime.

Book Description
Johnny Quinn shares his “wild dream” of playing in the NFL, being crushed after getting cut three times, losing $2.6 million in contracts, and blowing out his knee. At age thirty, when most professional athletes are considered “over the hill,” Johnny was competing for Team USA in the sport of bobsled at the 2014 Winter Olympics in Sochi, Russia. This book ushers readers through the valleys of life to the thrills of rocketing down icy mountains at 80+ mph with no seat belt. Discover how the author overcame failure on the road to achieving greatness. From an NFL failure to a US Olympian, Johnny Quinn had a “what’s next” attitude that led him to success he had never imagined. In Push, he looks at failure as a season of life rather than a death sentence. He provides incredible insight into the “what’s next” instead of “what could have been.” We all experience failure at some level; Quinn equips us to embrace change, accept risks, and learn to push through barriers, to live life on purpose.

Book Description
Breaking Through the Access Barrier argues that the policies designed to address inequalities in college access are failing to address underlying issues of inequality. This book introduces academic capital formation (ACF), a groundbreaking new theory defined by family knowledge of educational options and the opportunities for pursuing them. The authors suggest focusing on intervention programs and public policy to promote improvement in academic preparation, college information, and student aid. This textbook offers: a new construct–academic capital–that integrates and draws upon existing literature on influencing access to college practical advice for better preparation and intervention real student outcomes, databases, and interviews taken from exemplary intervention programs empirical research illuminating the role of class reproduction in education and how interventions (financial, academic, and networking) can reduce student barriers quantitative and qualitative analysis of the importance and effectiveness of several major policy interventions. Written for courses on higher education policy and policy analysis, readers will find Breaking Through the Access Barrier offers valuable advice for working within new policy frameworks and reshaping the future of educational opportunities and access for under-represented students from disadvantaged backgrounds.
