The modern "data center" is a complex arena, with physical and virtual servers, multiple OS environments, and complex networking that frequently spans multiple locations. The need to simplify has never been greater. Mesos, an innovative open-source cluster management platform, transforms the whole data center into a single pool of compute, memory, and storage resources that can be allocated, automated, and scaled as if working with a single super-computer. Mesos is an ideal environment for deploying containerized applications at scale, and it's generating a huge buzz in the big data world as a saner environment for running Spark and Hadoop. Mesos in Action introduces the Apache Mesos cluster manager and the concept of application-centric infrastructure. It guides readers from their first steps in deploying a highly-available Mesos cluster through deploying applications in production and writing native Mesos frameworks. It will show how to scale to thousands of nodes, while providing resource isolation between processes using Linux and Docker containers. It contains practical techniques for deploying applications using popular key frameworks, including Marathon, Chronos, and Aurora. Along the way, the book dives into Mesos internals, including fault tolerance, slave attributes, and resource scheduling and Mesos administration, including logging, monitoring, framework authorization, and slave recovery.

This book is a snapshot of the vision shared by outstanding scientists on the key theoretical and experimental issues in Mesoscopic Physics. Quantum properties of electrons in solid state devices and transport in semiconducting and superconducting low-dimensional systems, are discussed, as well as the basis of quantum computing (entanglement, noise decoherence and read-out). Each chapter collects the material presented at a Varenna School course of last year, by leading experts in the field. The reader gets a flavor, how theorists and experimentalists are paving the way to the physical realization of solid state qubits, the basic units of the new logic and memory elements for quantum processing. He will be surprised in finding that mesoscopic solid state devices, which were invented just yesterday ( think of the Single Electron Transistor, or the Cooper Pair Box) are currently used as charge-sensing applications in the equipment of frontier research laboratories. These devices contribute as probing systems to produce evidence on still unsettled questions in topics like the metal-insulator transition in disordered two dimensional systems, quantum Hall conductance in heterostructures, or Kondo conductance in quantum dots.

Feingranulare Systeme mit Microservices aufbauen Design, Entwicklung, Deployment, Testen und Monitoring Sicherheitsaspekte, Authentifizierung und Autorisierung Verteilte Systeme haben sich in den letzten Jahren stark verändert: Große monolithische Architekturen werden zunehmend in viele kleine, eigenständige Microservices aufgespalten. Aber die Entwicklung solcher Systeme bringt Herausforderungen ganz eigener Art mit sich. Dieses Buch richtet sich an Softwareentwickler, die sich über die zielführenden Aspekte von Microservice-Systemen wie Design, Entwicklung, Testen, Deployment und Monitoring informieren möchten. Sam Newman veranschaulicht und konkretisiert seine ganzheitliche Betrachtung der grundlegenden Konzepte von Microservice-Architekturen anhand zahlreicher praktischer Beispiele und Ratschläge. Er geht auf die Themen ein, mit denen sich Systemarchitekten und Administratoren bei der Einrichtung, Verwaltung und Entwicklung dieser Architekturen in jedem Fall auseinandersetzen müssen. Aus dem Inhalt: Vorteile von Microservices Gestaltung von Services Ausrichtung der Systemarchitektur an der Organisationsstruktur Möglichkeiten zur Integration von Services Schrittweise Aufspaltung einer monolithischen Codebasis Deployment einzelner Microservices mittels Continuous Integration Testen und Monitoring verteilter Systeme Sicherheitsaspekte Authentifizierung und Autorisierung zwischen Benutzer und Service bzw. zwischen Services untereinander Skalierung von Microservice-Architekturen »Microservice-Architekturen besitzen viele interessante Eigenschaften, allerdings sind bei der Umstellung so einige Fallstricke zu beachten. Dieses Buch wird Ihnen helfen herauszufinden, ob Microservices für Ihre Zwecke geeignet sind und zeigt Ihnen, wie Sie die Fallstricke umgehen können.« Martin Fowler, Chief Scientist, ThoughtWorks

Moral Codes and Social Structure in Ancient Greece

An exercise in cultural sociology, Moral Codes and Social Structure in Ancient Greece seeks to explicate the dynamic currents of classical Hellenic ethics and social philosophy by situating those idea-complexes in their socio-historical and intellectual contexts. Central to this enterprise is a comprehensive historical-sociological analysis of the Polis form of social organization, which charts the evolution of its basic institutions, roles, statuses, and class relations. From the Dark Age period of “genesis” on to the Hellenistic era of “eclipse” by the emergent forces of imperial patrimonialism, Polis society promoted and sustained corresponding normative codes which mobilized and channeled the requisite emotive commitments and cognitive judgments for functional proficiency under existing conditions of life. The aristocratic warrior-ethos canonized in the Homeric epics; the civic ideology of equality and justice espoused by reformist lawgivers and poets; the democratization of status honor and martial virtue that attended the shift to hoplite warfare; the philosophical exaltation of the Polis-citizen bond as found in the architectonic visions of Plato and Aristotle; and the subsequent retreat from civic virtues and the interiorization of value articulated by the Skeptics, Epicureans, and Stoics, new age philosophies in a world remade by Alexander’s conquests—these are the key phases in the evolving currents of Hellenic moral discourse, as structurally framed by transformations within the institutional matrix of Polis society.

Working with big data can be complex and challenging, in part because of the multiple analysis frameworks and tools required. Apache Spark is a big data processing framework perfect for analyzing near-real-time streams and discovering historical patterns in batched data sets. But Spark goes much further than other frameworks. By including machine learning and graph processing capabilities, it makes many specialized data processing platforms obsolete. Spark's unified framework and programming model significantly lowers the initial infrastructure investment, and Spark's core abstractions are intuitive for most Scala, Java, and Python developers. Spark in Action teaches readers to use Spark for stream and batch data processing. It starts with an introduction to the Spark architecture and ecosystem followed by a taste of Spark's command line interface. Readers then discover the most fundamental concepts and abstractions of Spark, particularly Resilient Distributed Datasets (RDDs) and the basic data transformations that RDDs provide. The first part of the book covers writing Spark applications using the the core APIs. Readers also learn how to work with structured data using Spark SQL, how to process near-real time data with Spark Streaming, how to apply machine learning algorithms with Spark MLlib, how to apply graph algorithms on graph-shaped data using Spark GraphX, and an introduction to Spark clustering. Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.

Based on the conviction that only translators who write poetry themselves can properly re-create the celebrated and timeless tragedies of Aeschylus, Sophocles, and Euripides, the Greek Tragedy in New Translations series offers new translations that go beyond the literal meaning of the Greek in order to evoke the poetry of the originals. Under the general editorship of Peter Burian and Alan Shapiro, each volume includes a critical introduction, commentary on the text, full stage directions, and a glossary of the mythical and geographical references in the play. En route to fight the Trojan War, the Greek army has abandoned Philoctetes, after the smell of his festering wound, mysteriously received from a snakebite at a shrine on a small island off Lemnos, makes it unbearable to keep him on ship. Ten years later, an oracle makes it clear that the war cannot be won without the assistance of Philoctetes and his famous bow, inherited from Hercules himself. Philoctetes focuses on the attempt of Neoptolemus and the hero Odysseus to persuade the bowman to sail with them to Troy. First, though, they must assuage his bitterness over having been abandoned, and then win his trust. But how should they do this--through trickery, or with the truth? To what extent do the ends justify the means? To what degree should personal integrity be compromised for the sake of public duty? These are among the questions that Sophocles puts forward in this, one of his most morally complex and penetrating plays.
