Book excerpt: Creating Cassandra is two love stories about the same man and woman set eight hundred years apart. The story begins in the 1990s as the Boston based author is seeking and ultimately finds his model for the Cassandra of his twelfth-century novella about a man and woman who will share their names in that other age. Both his muse and the character she inspires are ambitious women. Both marry powerful men who will die leaving them and their not necessarily legitimate fortunes vulnerable. And each will call upon her centurys version of a knight, mercenary or gangster to hold on to what otherwise would be lost. The obsessions that drive the superstitious author and his determined Cassandra influence what will come to pass in the novella, just as what the author ascribes to his twelfth-century characters influences the actions of his Cassandra and the author himself. When the two worlds meet, there are ample warnings of danger but as you would expect in the case of a Cassandra, no warning or prophesy is heeded. Neither the author nor Cassandra would ever have anticipated the price that they had to pay for the worlds they had fought so hard to create in either century. What they created would forever change the course of their lives. From Creating Cassandra Giangreco slowly put his arm around Cassandra. He held her tightly as he said Anyone who writes a biography that is supposed to tell all is a fool, a liar or a person who has not lived much of a life. You know that, Cassandra. Think of your own life. And I would not want you to be any different than how you are.

Download or read book Cassandra Speaks written by Elizabeth Lesser and published by HarperCollins. This book was released on 2020-09-15 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: What story would Eve have told about picking the apple? Why is Pandora blamed for opening the box? And what about the fate of Cassandra who was blessed with knowing the future but cursed so that no one believed her? What if women had been the storytellers? Elizabeth Lesser believes that if women’s voices had been equally heard and respected throughout history, humankind would have followed different hero myths and guiding stories—stories that value caretaking, champion compassion, and elevate communication over vengeance and violence. Cassandra Speaks is about the stories we tell and how those stories become the culture. It’s about the stories we still blindly cling to, and the ones that cling to us: the origin tales, the guiding myths, the religious parables, the literature and films and fairy tales passed down through the centuries about women and men, power and war, sex and love, and the values we live by. Stories written mostly by men with lessons and laws for all of humanity. We have outgrown so many of them, and still they endure. This book is about what happens when women are the storytellers too—when we speak from our authentic voices, when we flex our values, when we become protagonists in the tales we tell about what it means to be human. Lesser has walked two main paths in her life—the spiritual path and the feminist one—paths that sometimes cross but sometimes feel at cross-purposes. Cassandra Speaks is her extraordinary merging of the two. The bestselling author of Broken Open and Marrow, Lesser is a beloved spiritual writer, as well as a leading feminist thinker. In this book she gives equal voice to the cool water of her meditative self and the fire of her feminist self. With her trademark gifts of both humor and insight, she offers a vision that transcends the either/or ideologies on both sides of the gender debate. Brilliantly structured into three distinct parts, Part One explores how history is carried forward through the stories a culture tells and values, and what we can do to balance the scales. Part Two looks at women and power and expands what it means to be courageous, daring, and strong. And Part Three offers “A Toolbox for Inner Strength.” Lesser argues that change in the culture starts with inner change, and that no one—woman or man—is immune to the corrupting influence of power. She provides inner tools to help us be both strong-willed and kind-hearted. Cassandra Speaks is a beautifully balanced synthesis of storytelling, memoir, and cultural observation. Women, men and all people will find themselves in the pages of this book, and will come away strengthened, opened, and ready to work together to create a better world for all people.

Download or read book Constructing Cassandra written by Milo Jones and published by Stanford University Press. This book was released on 2013-08-21 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Constructing Cassandra analyzes the intelligence failures at the CIA that resulted in four key strategic surprises experienced by the US: the Cuban Missile Crisis in 1962, the Iranian revolution of 1978, the collapse of the USSR in 1991, and the 9/11 terrorist attacks—surprises still play out today in U.S. policy. Although there has been no shortage of studies exploring how intelligence failures can happen, none of them have been able to provide a unified understanding of the phenomenon. To correct that omission, this book brings culture and identity to the foreground to present a unified model of strategic surprise; one that focuses on the internal make-up the CIA, and takes seriously those Cassandras who offered warnings, but were ignored. This systematic exploration of the sources of the CIA's intelligence failures points to ways to prevent future strategic surprises.

Download or read book Beginning Apache Cassandra Development written by Vivek Mishra and published by Apress. This book was released on 2014-12-12 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beginning Apache Cassandra Development introduces you to one of the most robust and best-performing NoSQL database platforms on the planet. Apache Cassandra is a document database following the JSON document model. It is specifically designed to manage large amounts of data across many commodity servers without there being any single point of failure. This design approach makes Apache Cassandra a robust and easy-to-implement platform when high availability is needed. Apache Cassandra can be used by developers in Java, PHP, Python, and JavaScript—the primary and most commonly used languages. In Beginning Apache Cassandra Development, author and Cassandra expert Vivek Mishra takes you through using Apache Cassandra from each of these primary languages. Mishra also covers the Cassandra Query Language (CQL), the Apache Cassandra analog to SQL. You'll learn to develop applications sourcing data from Cassandra, query that data, and deliver it at speed to your application's users. Cassandra is one of the leading NoSQL databases, meaning you get unparalleled throughput and performance without the sort of processing overhead that comes with traditional proprietary databases. Beginning Apache Cassandra Development will therefore help you create applications that generate search results quickly, stand up to high levels of demand, scale as your user base grows, ensure operational simplicity, and—not least—provide delightful user experiences.

Download or read book Reactive Spring written by Josh Long and published by . This book was released on 2020-09-15 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Microservices and big-data increasingly confront us with the limitations of traditional input/output. In traditional IO, work that is IO-bound dominates threads. This wouldn't be such a big deal if we could add more threads cheaply, but threads are expensive on the JVM, and most other platforms. Even if threads were cheap and infinitely scalable, we'd still be confronted with the faulty nature of networks. Things break, and they often do so in subtle, but non-exceptional ways. Traditional approaches to integration bury the faulty nature of networks behind overly simplifying abstractions. We need something better.Join Spring Developer Advocate Josh Long for an introduction to reactive programming in the Spring ecosystem, leveraging the reactive streams specification, Reactor, Spring Boot, Spring Cloud and so much more.This book will cover important concepts in reactive programming including project Reactor and the reactive streams specification, data access, web programming, RPC with protocols like RSocket, testing, and integration and composition, and more.
