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."

Edith Grossman's definitive English translation of the Spanish masterpiece. Widely regarded as the world's first modern novel, and one of the funniest and most tragic books ever written, Don Quixote chronicles the famous picaresque adventures of the noble knight-errant Don Quixote of La Mancha and his faithful squire, Sancho Panza, as they travel through sixteenth-century Spain. Unless you read Spanish, you've never read Don Quixote. "Though there have been many valuable English translations of Don Quixote, I would commend Edith Grossman's version for the extraordinarily high quality of her prose. The Knight and Sancho are so eloquently rendered by Grossman that the vitality of their characterization is more clearly conveyed than ever before. There is also an astonishing contextualization of Don Quixote and Sancho in Grossman's translation that I believe has not been achieved before. The spiritual atmosphere of a Spain already in steep decline can be felt throughout, thanks to her heightened quality of diction. Grossman might be called the Glenn Gould of translators, because she, too, articulates every note. Reading her amazing mode of finding equivalents in English for Cervantes's darkening vision is an entrance into a further understanding of why this great book contains within itself all the novels that have followed in its sublime wake." From the Introduction by Harold Bloom Miguel de Cervantes was born on September 29, 1547, in Alcala de Henares, Spain. At twenty-three he enlisted in the Spanish militia and in 1571 fought against the Turks in the battle of Lepanto, where a gunshot wound permanently crippled his left hand. He spent four more years at sea and then another five as a slave after being captured by Barbary pirates. Ransomed by his family, he returned to Madrid but his disability hampered him; it was in debtor's prison that he began to write Don Quixote. Cervantes wrote many other works, including poems and plays, but he remains best known as the author of Don Quixote. He died on April 23, 1616.

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.

In this incredibly penetrating talk, Krishnamurti describes the psychological pressures of life and how these pressures affect right living: We were saying that any form of pressure on the brain affects our whole way of life. We were also saying that this pressure affects our activities, our attitudes, our character, and our way of living. The pressure--economic, social, ethical, and religious--invariably distorts not only our actions but the quality of the brain ... ideals affect, oppress, and act as pressure upon our daily life. Is it possible not to have any ideals but only deal with actually what is--then there is no pressure whatsoever. Krishnamurti goes on to say that, unless the mind is free of pressure, there is no new way of living. He states that this insight on freedom requires a great deal of investigation into the whole nature and movement of pressure.

Prince Liam. Prince Frederic. Prince Duncan. Prince Gustav. You’ve never heard of them, have youThese are the princes who saved Sleeping Beauty, Cinderella, Snow White, and Rapunzel, respectively, and yet, thanks to those lousy bards who wrote the tales, you likely know them only as Prince Charming. But all of this is about to change. Rejected by their princesses and cast out of their castles, the princes stumble upon an evil plot that could endanger each of their kingdoms. Now it up to them to triumph over their various shortcomings, take on trolls, bandits, dragons, witches, and other assorted terrors, and become the heroes no one ever thought they could be. Christopher Healy Hero Guide to Saving Your Kingdom is a completely original take on the world of fairy tales, the truth about what happens after “happily ever after.” It a must-have for middle grade readers who enjoy their fantasy adventures mixed with the humor of the Diary of a Wimpy Kid books. Witty black-and-white drawings by Todd Harris add to the fun.

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.

Due to copyright restrictions, this eBook may not contain all of the images available in the print edition. It was the summer Coltrane died, the summer of love and riots, and the summer when a chance encounter in Brooklyn led two young people on a path of art, devotion, and initiation. Patti Smith would evolve as a poet and performer, and Robert Mapplethorpe would direct his highly provocative style toward photography. Bound in innocence and enthusiasm, they traversed the city from Coney Island to Forty-second Street, and eventually to the celebrated round table of Max's Kansas City, where the Andy Warhol contingent held court. In 1969, the pair set up camp at the Hotel Chelsea and soon entered a community of the famous and infamous the influential artists of the day and the colorful fringe. It was a time of heightened awareness, when the worlds of poetry, rock and roll, art, and sexual politics were colliding and exploding. In this milieu, two kids made a pact to take care of each other. Scrappy, romantic, committed to create, and fueled by their mutual dreams and drives, they would prod and provide for one another during the hungry years. Just Kids begins as a love story and ends as an elegy. It serves as a salute to New York City during the late sixties and seventies and to its rich and poor, its hustlers and hellions. A true fable, it is a portrait of two young artists' ascent, a prelude to fame.

Earth is our Business takes forward the argument of Polly Higgins’ first book, Eradicating Ecocide. This book proposes new Earth law, but it is also about something more than law: it advocates a new form of leadership which places the health and well-being of people and planet first. Polly Higgins shows how law can provide the tools and be a bridge to a new way of doing business. She argues, in fact, that Earth is the business of us all, not the exclusive preserve of the executives of the world’s top corporations. Expanding on the proposal in her first book to make Ecocide an international crime, this book sets out the institutional framework for sustainable development and international environmental governance. It proposes new rules of the game to transform our economies, energy supplies and political landscape in a radical, but practical, way. The implications of Polly Higgins’ proposal are far-reaching and profound. Like her award-winning first book, Earth is our Business is written for anyone who is engaging in the new and emerging discourse about the future of our planet and sustainable development. Instead of merely examining the problem, Earth is our Business sets out a solution: new rules of the game. They are, says Polly Higgins, a new set of laws based on the sacredness of all life. Included as appendices are a draft Ecocide Act, a proposal for revising World Bank investment rules, and the indictment used in the mock Ecocide Trial held in the UK Supreme Court in September 2011.

The Teaching of Reality is, as far as we know, the first translation into English of Tattvopade?a, a work attributed to the great spiritual teacher ?ankara.

Create robust and maintainable Java applications using the functional style of programmingAbout This BookExplore how you can blend object-oriented and functional programming styles in JavaUse lambda expressions to write flexible and succinct codeA tutorial that strengthens your fundamentals in functional programming techniques to enhance your applications Who This Book Is For If you are a Java developer with object-oriented experience and want to use a functional programming approach in your applications, then this book is for you. All you need to get started is familiarity with basic Java object-oriented programming concepts.What You Will LearnUse lambda expressions to simplyfy codeUse function composition to achieve code fluencyApply streams to simply implementations and achieve parallelismIncorporate recursion to support an application’s functionalityProvide more robust implementations using OptionalsImplement design patterns with less codeRefactor object-oriented code to create a functional solutionUse debugging and testing techniques specific to functional programs In Detail Functional programming is an increasingly popular technology that allows you to simplify many tasks that are often cumbersome and awkward using an object-oriented approach. It is important to understand this approach and know how and when to apply it. Functional programming requires a different mindset, but once mastered it can be very rewarding. This book simplifies the learning process as a problem is described followed by its implementation using an object-oriented approach and then a solution is provided using appropriate functional programming techniques. Writing succinct and maintainable code is facilitated by many functional programming techniques including lambda expressions and streams. In this book, you will see numerous examples of how these techniques can be applied starting with an introduction to lambda expressions. Next, you will see how they can replace older approaches and be combined to achieve surprisingly elegant solutions to problems. This is followed by the investigation of related concepts such as the Optional class and monads, which offer an additional approach to handle problems. Design patterns have been instrumental in solving common problems. You will learn how these are enhanced with functional techniques. To transition from an object-oriented approach to a functional one, it is useful to have IDE support. IDE tools to refactor, debug, and test functional programs are demonstrated through the chapters. The end of the book brings together many of these functional programming techniques to create a more comprehensive application. You will find this book a very useful resource to learn and apply functional programming techniques in Java.Style and approach In this tutorial, each chapter starts with an introduction to the terms and concepts covered in that chapter. It quickly progresses to contrast an object-oriented approach with a functional approach using numerous code examples.

First published as Johnson’s Life of London, now released with new material following Jubilee and Olympic celebrations in 2012. This updated history of London shows that the ingenuity, diversity, creativity and enterprise of the city are second to none… London’s buildings may be famous, London’s history may be lengthy and illustrious, but it is London’s people who have given, and continue to give, the city its exuberant and exhilarating profile. London of the Olympic and Jubilee summer displayed Londoners on a world stage, but this is a city which has always lived on the energy and skills of its people, drawn to the capital from all over the country and the world. Boris Johnson shares with us his pleasure at London’s vitality and unique character, and selects the people who in his view have contributed so much to the spirit of London – some very famous figures, some more obscure. He includes everyone from the Romans to one of the author’s predecessors as mayor, Dick Whittington; from John Wilkes (a strong upholder of the freedom of the press) to J.W. Turner; from Chaucer to Gandhi, and through to modern times.
