"Exhilarating . . . How often can you say about a harrowing, unquiet book that it makes you wrestle with your soul?" —Neel Mukherjee, The Times (London) It's 1948 and the Arab villagers of Khirbet Khizeh are about to be violently expelled from their homes. A young Israeli soldier who is on duty that day finds himself battling on two fronts: with the villagers and, ultimately, with his own conscience. Published just months after the founding of the state of Israel and the end of the 1948 war, the novella Khirbet Khizeh was an immediate sensation when it first appeared. Since then, the book has continued to challenge and disturb, even finding its way onto the school curriculum in Israel. The various debates it has prompted would themselves make Khirbet Khizeh worth reading, but the novella is much more than a vital historical document: it is also a great work of art. Yizhar's haunting, lyrical style and charged view of the landscape are in many ways as startling as his wrenchingly honest view of modern Israel's primal scene. Considered a modern Hebrew masterpiece, Khirbet Khizeh is an extraordinary and heartbreaking book that is destined to be a classic of world literature.

These proceedings present the results of the Eleventh International Conference on Dependability and Complex Systems DepCoS-RELCOMEX which took place in a picturesque Brunów Palace in Poland from 27th June to 1st July, 2016. DepCoS-RELCOMEX is a series of international conferences organized annually by Department of Computer Engineering of Wrocław University of Science and Technology since 2006. The roots of the series go as far back as to the seventies of the previous century – the first RELCOMEX conference took place in 1977 – and now its main aim is to promote a multi-disciplinary approach to dependability problems in theory and engineering practice of complex systems. Complex systems, nowadays most often computer-based and distributed, are built upon a variety of technical, information, software and human resources. The challenges in their design, analysis and maintenance not only originate from the involved technical and organizational structures but also from the complexity of the information processes that must be efficiently executed in a diverse, often hostile operational environment. Traditional methods of reliability evaluation focused only on technical resources are usually insufficient in this context and more innovative, multidisciplinary methods of dependability analysis must be applied. The diversity of the topics which need to be considered is well illustrated by the selection of the submissions in these proceedings with their subjects ranging from mathematical models and design methodologies through software engineering and data security issues up to practical problems in technical, e.g. transportation, systems.

Since the introduction of Bitcoin—the first widespread application driven by blockchain—the interest of the public and private sectors in blockchain has skyrocketed. In recent years, blockchain-based fabrics have been used to address challenges in diverse fields such as trade, food production, property rights, identity-management, aid delivery, health care, and fraud prevention. This widespread interest follows from fundamental concepts on which blockchains are built that together embed the notion of trust, upon which blockchains are built. 1. Blockchains provide data transparancy. Data in a blockchain is stored in the form of a ledger, which contains an ordered history of all the transactions. This facilitates oversight and auditing. 2. Blockchains ensure data integrity by using strong cryptographic primitives. This guarantees that transactions accepted by the blockchain are authenticated by its issuer, are immutable, and cannot be repudiated by the issuer. This ensures accountability. 3. Blockchains are decentralized, democratic, and resilient. They use consensus-based replication to decentralize the ledger among many independent participants. Thus, it can operate completely decentralized and does not require trust in a single authority. Additions to the chain are performed by consensus, in which all participants have a democratic voice in maintaining the integrity of the blockchain. Due to the usage of replication and consensus, blockchains are also highly resilient to malicious attacks even when a significant portion of the participants are malicious. It further increases the opportunity for fairness and equity through democratization. These fundamental concepts and the technologies behind them—a generic ledger-based data model, cryptographically ensured data integrity, and consensus-based replication—prove to be a powerful and inspiring combination, a catalyst to promote computational trust. In this book, we present an in-depth study of blockchain, unraveling its revolutionary promise to instill computational trust in society, all carefully tailored to a broad audience including students, researchers, and practitioners. We offer a comprehensive overview of theoretical limitations and practical usability of consensus protocols while examining the diverse landscape of how blockchains are manifested in their permissioned and permissionless forms.

This book covers the most essential techniques for designing and building dependable distributed systems, from traditional fault tolerance to the blockchain technology. Topics include checkpointing and logging, recovery-orientated computing, replication, distributed consensus, Byzantine fault tolerance, as well as blockchain. This book intentionally includes traditional fault tolerance techniques so that readers can appreciate better the huge benefits brought by the blockchain technology and why it has been touted as a disruptive technology, some even regard it at the same level of the Internet. This book also expresses a grave concern on using traditional consensus algorithms in blockchain because with the limited scalability of such algorithms, the primary benefits of using blockchain in the first place, such as decentralization and immutability, could be easily lost under cyberattacks.

One of President Obama's Favorite Books of the Year | A New York Times Notable Book | One of the Wall Street Journal Ten Best Books of the Year "Missionaries is a courageous book: It doesn’t shy away, as so much fiction does, from the real world.” —Juan Gabriel Vásquez, The New York Times Book Review “A sweeping, interconnected novel of ideas in the tradition of Joseph Conrad and Norman Mailer . . . By taking a long view of the ‘rational insanity’ of global warfare, Missionaries brilliantly fills one of the largest gaps in contemporary literature.” —The Wall Street Journal The debut novel from the National Book Award-winning author of Redeployment A group of Colombian soldiers prepares to raid a drug lord's safe house on the Venezuelan border. They're watching him with an American-made drone, about to strike using military tactics taught to them by U.S. soldiers who honed their skills to lethal perfection in Iraq. In Missionaries, Phil Klay examines the globalization of violence through the interlocking stories of four characters and the conflicts that define their lives. For Mason, a U.S. Army Special Forces medic, and Lisette, a foreign correspondent, America's long post-9/11 wars in the Middle East exerted a terrible draw that neither is able to shake. Where can such a person go next? All roads lead to Colombia, where the US has partnered with local government to keep predatory narco gangs at bay. Mason, now a liaison to the Colombian military, is ready for the good war, and Lisette is more than ready to cover it. Juan Pablo, a Colombian officer, must juggle managing the Americans' presence and navigating a viper's nest of factions bidding for power. Meanwhile, Abel, a lieutenant in a local militia, has lost almost everything in the seemingly endless carnage of his home province, where the lines between drug cartels, militias, and the state are semi-permeable. Drawing on six years of research in America and Colombia into the effects of the modern way of war on regular people, Klay has written a novel of extraordinary suspense infused with geopolitical sophistication and storytelling instincts that are second to none. Missionaries is a window not only into modern war, but into the individual lives that go on long after the drones have left the skies.
