A finalist for the National Book Award! A ferocious firefight with Iraqi insurgents at the battle of Al-Ansakar Canal three minutes and forty-three seconds of intense warfare caught on tape by an embedded Fox News crew has transformed the eight surviving men of Bravo Squad into America most sought-after heroes. For the past two weeks, the Bush administration has sent them on a media-intensive nationwide Victory Tour to reinvigorate public support for the war. Now, on this chilly and rainy Thanksgiving, the Bravos are guests of America Team, the Dallas Cowboys, slated to be part of the halftime show alongside the superstar pop group Destiny's Child. Among the Bravos is the Silver Star winning hero of Al-Ansakar Canal, Specialist William Lynn, a nineteen-year-old Texas native. Amid clamoring patriots sporting flag pins on their lapels and Support Our Troops bumper stickers on their cars, the Bravos are thrust into the company of the Cowboys' hard-nosed businessman/owner and his coterie of wealthy colleagues; a luscious born-again Cowboys cheerleader; a veteran Hollywood producer; and supersized pro players eager for a vicarious taste of war. Among these faces Billy sees those of his family his worried sisters and broken father and Shroom, the philosophical sergeant who opened Billy mind and died in his arms at Al-Ansakar. Over the course of this day, Billy will begin to understand difficult truths about himself, his country, his struggling family, and his brothers-in-arms soldiers both dead and alive. In the final few hours before returning to Iraq, Billy will drink and brawl, yearn for home and mourn those missing, face a heart-wrenching decision, and discover pure love and a bitter wisdom far beyond his years. Poignant, riotously funny, and exquisitely heartbreaking, Billy Lynn Long Halftime Walk is a devastating portrait of our time, a searing and powerful novel that cements Ben Fountain reputation as one of the finest writers of his generation.

Adonais begins as he stands on the Iberian Peninsula and looks out towards the coast of North Africa, fighting for the strength to go with his inner leadings and follow his destiny that lies beyond that coast. The story observes the young Friar as he makes his journey from the Peninsula?s southern tip through the Alpujarra to a Gharnata that is feeling a new rise in sectarian tension and is hearing news of violent events across the border in Christian Sevilla. In Gharnata he meets his childhood friend Miriam in the house of Rabbi Andrew, the spiritual head of Gharnata?s distinguished Jewish population. They agree to share the journey together to her forest community that is on the way to his final destination which is the Christian frontier city of Jaen. These young orphan children who grew up as closest friends and confidantes but have blossomed into beautiful adults have a deep and soul searching time of facing a lot of their confusion over their adult relationship which causes, especially Adonais to face some of the ghosts of his past. Miriam?s joyous wedding occurs in the vibrant community of which she is a key part and the whole event provides cathartic, healing for many of the participants.

Build real-world, industry-strength data storage solutions with time-tested design methodologies using CassandraAbout This BookExplore design patterns which co-exist with legacy data stores, migration from RDBMS, and caching technologies with CassandraLearn about design patterns and use Cassandra to provide consistency, availability, and partition tolerance guarantees for applicationsHandle temporal data for analytical purposes Who This Book Is For This book is intended for big data developers who are familiar with the basics of Cassandra and wish to understand and utilize Cassandra design patterns to develop real-world big data solutions. Prior knowledge of RDBMS solutions is assumed.What You Will LearnEnable Cassandra to co-exist with RDBMS and other legacy data storesExplore various design patterns to build effective and robust storage solutionsMigrate from RDBMS-based data stores and caching solutions to CassandraUnderstand the behaviour of Cassandra when trying to balance the needs of consistency, availability, and partition toleranceDeal with time stamps related to data effectivelySee how Cassandra can be used in analytical use casesApply the design patterns covered in this book in real-world use cases In Detail There are many NoSQL data stores used by big data applications. Cassandra is one of the most widely used NoSQL data stores that is frequently used by a huge number of heavy duty Internet-scale applications. Unlike the RDBMS world, the NoSQL landscape is very diverse and there is no one way to model data stores. This mandates the need to have good solutions to commonly seen data store design problems. Cassandra addresses such common problems simply. If you are new to Cassandra but well-versed in RDBMS modeling and design, then it is natural to model data in the same way in Cassandra, resulting in poorly performing applications and losing the real purpose of Cassandra. If you want to learn to make the most of Cassandra, this book is for you. This book starts with strategies to integrate Cassandra with other legacy data stores and progresses to the ways in which a migration from RDBMS to Cassandra can be accomplished. The journey continues with ideas to migrate data from cache solutions to Cassandra. With this, the stage is set and the book moves on to some of the most commonly seen problems in applications when dealing with consistency, availability, and partition tolerance guarantees. Cassandra is exceptionally good at dealing with temporal data and patterns such as the time-series pattern and log pattern, which are covered next. Many NoSQL data stores fail miserably when a huge amount of data is read for analytical purposes, but Cassandra is different in this regard. Keeping analytical needs in mind, you’ll walk through different and interesting design patterns. No theoretical discussions are complete without a good set of use cases to which the knowledge gained can be applied, so the book concludes with a set of use cases you can apply the patterns you’ve learned.Style and approach This book is written in very simple language and an engaging style complete with examples in every chapter and real-world use cases at the end of the book.

One of the most popular and beloved introductions to the concept of faith ever written, Mere Christianity has sold millions of copies worldwide. The book brings together C. S. Lewis legendary radio broadcasts during the war years, in which he set out simply to explain and defend the belief that has been common to nearly all Christians at all times. Rejecting the boundaries that divide Christianity many denominations, Mere Christianity provides an unequalled opportunity for believers and nonbelievers alike to absorb a powerful, rational case for the Christian faith.

A milestone in the history of popular theology, The Screwtape Letters is an iconic classic on spiritual warfare and the dynamics of temptation. This profound and striking narrative takes the form of a series of letters from Screwtape, a devil high in the Infernal Civil Service, to his nephew Wormwood, a junior colleague engaged in his first mission on earth, trying to secure the damnation of a young man who has just become a Christian. Although the young man initially looks to be a willing victim, he changes his ways and is "lost" to the young devil. Dedicated to Lewis's friend and colleague J. R. R. Tolkien, The Screwtape Letters is a timeless classic on spiritual conflict and the psychology of temptation which are part of our religious experience.

Both astonishing and prophetic, The Abolition of Man remains one of C. S. Lewis's most controversial works. Lewis sets out to persuade his audience of the ongoing importance and relevance of universal objective values, such as courage and honor, and the foundational necessity of natural law. He also makes a cogent case that a retreat from these pillars of our educational system, even if in the name of "scientism," would be catastrophic. National Review lists it as number seven on their "100 Best Nonfiction Books of the Twentieth Century."
