Algorithmen und Datenstrukturen
Algorithmen und Datenstrukturen von Grund auf verstehen* Fundierte Einführung mit klarem didaktischen Aufbau* Mit konkreten Anwendungsbeispielen * Eine reichhaltige Fundgrube für Lehre und SelbststudiumKenntnisse von Algorithmen und Datenstrukturen sind ein Grundbaustein des Studiums der Informatik und verwandter Fachrichtungen. Das Buch behandelt diese Thematik in Verbindung mit der Programmiersprache Java und schlägt so eine Brücke zwischen den klassischen Lehrbüchern zur Theorie von Algorithmen und Datenstrukturen und den praktischen Einführungen in eine konkrete Programmiersprache.Die konkreten Algorithmen und deren Realisierung in Java werdenumfassend dargestellt. Daneben werden die theoretischen Grundlagen vermittelt, die in Programmiersprachen-Kursen oft zu kurz kommen: abstrakte Maschinenmodelle, Berechenbarkeit, Algorithmenparadigmen sowie parallele und verteilte Abläufe. Einen weiteren Schwerpunkt bilden Datenstrukturen wie Listen, Bäume, Graphen und Hashtabellen sowie deren objektorientierteImplementierung mit modernen Methoden der Softwareentwicklung.Die 6.

Interconnection Network Reliability Evaluation
THIS BOOK PRESENTS NOVEL AND EFFICIENT TOOLS, TECHNIQUES AND APPROACHES FOR RELIABILITY EVALUATION, RELIABILITY ANALYSIS, AND DESIGN OF RELIABLE COMMUNICATION NETWORKS USING GRAPH THEORETIC CONCEPTS.In recent years, human beings have become largely dependent on communication networks, such as computer communication networks, telecommunication networks, mobile switching networks etc., for their day-to-day activities. In today's world, humans and critical machines depend on these communication networks to work properly. Failure of these communication networks can result in situations where people may find themselves isolated, helpless and exposed to hazards. It is a fact that every component or system can fail and its failure probability increases with size and complexity.The main objective of this book is to devize approaches for reliability modeling and evaluation of such complex networks. Such evaluation helps to understand which network can give us better reliability by their design. New designs of fault-tolerant interconnection network layouts are proposed, which are capable of providing high reliability through path redundancy and fault tolerance through reduction of common elements in paths. This book covers the reliability evaluation of various network topologies considering multiple reliability performance parameters (two terminal reliability, broadcast reliability, all terminal reliability, and multiple sources to multiple destinations reliability).DR.

Systems and Network Infrastructure Integration
IT infrastructures are now essential in all areas and sectors of human activity; they are the cornerstone of any information system. Thus, it is clear that the greatest of care must be given to their design, implementation, security and supervision in order to ensure optimum functionality and better performance. Within this context, Systems and Network Infrastructure Integration presents the methodological and theoretical principles necessary to successfully carry out an integration project for network and systems infrastructures. This book is aimed at anyone interested in the field of networks in general. In particular, it is intended for students of fields relating to networks and computer systems who are called upon to integrate their knowledge and skills, gained throughout their academic study, into a comprehensive project to set up a complete infrastructure, while respecting the necessary specifications.SAIDA HELALI is a university lecturer in Information Technology (specializing in networks and information systems) at the Institut Supérieur des Etudes Technologiques de Radès (Tunisia).

Exposed
DISCOVER WHY PRIVACY IS A COUNTERPRODUCTIVE, IF NOT OBSOLETE, CONCEPT IN THIS STARTLING NEW BOOKIt's only a matter of time-- the modern notion of privacy is quickly evaporating because of technological advancement and social engagement. Whether we like it or not, all our actions and communications are going to be revealed for everyone to see. Exposed: How Revealing Your Data and Eliminating Privacy Increases Trust and Liberates Humanity takes a controversial and insightful look at the concept of privacy and persuasively argues that preparing for a post-private future is better than exacerbating the painful transition by attempting to delay the inevitable. Security expert and author Ben Malisow systematically dismantles common notions of privacy and explains how:* Most arguments in favor of increased privacy are wrong* Privacy in our personal lives leaves us more susceptible to being bullied or blackmailed* Governmental and military privacy leads to an imbalance of power between citizen and state* Military supremacy based on privacy is an obsolete conceptPerfect for anyone interested in the currently raging debates about governmental, institutional, corporate, and personal privacy, and the proper balance between the public and the private, Exposed also belongs on the shelves of security practitioners and policymakers everywhere.BEN MALISOW has been involved in information security and education for over two decades. He designed and delivered the Carnegie Mellon University CISSP prep course, served as a US Air Force officer, and was Information Security System Manager for the Federal Bureau of Investigation's most highly classified counterterror intelligence-sharing network.

The Common Lisp Condition System
Discover the functioning and example uses of the Common Lisp condition system. This book supplements already existing material for studying Common Lisp as a language by providing detailed information about the Lisp condition system and its control flow mechanisms; it also describes an example ANSI-conformant implementation of the condition system.In part 1 of The Common Lisp Condition System, the author introduces the condition system using a bottom-up approach, constructing it piece by piece. He uses a storytelling approach to convey the foundation of the condition system, dynamically providing code to alter the behavior of an existing program. Later, in part 2, you’ll implement a full and complete ANSI-conformant condition system while examining and testing each piece of code that you write.Throughout, the author demonstrates how to extend Lisp using Lisp itself by using the condition system as an example. This is done while paying proper attention to the CL restart subsystem, giving it attention on a par with the handler subsystem. After reading and using this book, you'll have learned about the inner functioning of the condition system, how to use it in your own Common Lisp coding and applications, and how to implement it from scratch, should such a need arise.WHAT YOU WILL LEARN* Examine the condition system and see why it is important in Common Lisp* Construct the condition system from scratch using foundational mechanisms provided by Common Lisp* Program the condition system and its control flow mechanisms to achieve practical results* Implement all parts of a condition system: conditions, restarts, handler- and restart-binding macros, signalling mechanisms, assertions, a debugger, and moreWHO THIS BOOK IS FORBeginning and intermediate Lisp programmers, as well as intermediate programmers of other programming languages.MICHAŁ "PHOE" HERDA is a programmer with contributions to multiple parts of the Common Lisp ecosystem: CL implementations, existing and widely-used CL utilities, documentation, and some of the new library ideas that he slowly pushes forwards and works on. The book The Common Lisp Condition System is his first work -- an attempt to create a tutorial on the condition system that was missing, even all the years after which ANSI Common Lisp was standardized.1: Basic Concepts2: Introducing the Condition System3: Implementing the Common Lisp Condition System4: Wrapping UpAppendix A: Implementation of Dynamic Variables in CAppendix B: Additional Utilities for Working with Common Lisp ConditionsAppendix C: Lisp Macros 101Appendix D: Condition System Reference

Vom Monolithen zu Microservices
Bestehende Systeme erfolgreich in eine Microservices-Architektur umgestaltenUnerlässliches Expertenwissen für Organisationen, die ihre Codebasis modernisieren wollen Autor des geschätzten Grundlagenwerks »Building Microservices« Orientierung und Anleitung für den anspruchsvollen Migrationsprozess Wie entflechtet man ein monolithisches System und überführt es in eine Microservices-Architektur? Und wie erhält man gleichzeitig den normalen Betrieb aufrecht? Sam Newman, Autor des viel beachteten Titels »Building Microservices«, beschreibt Szenarien und erprobte Strategien, um bestehende Systeme erfolgreich zu migrieren: von der ersten Planung bis zum Zerlegen von Anwendung und Datenbank. Newman greift hierbei auf viele anschauliche Beispiele zurück, stellt aufschlussreiche Pattern für die Migration vor und gibt praktische Ratschläge. Für Organisationen, die ihre Codebasis in Richtung einer Microservices-Architektur überführen und nicht komplett neu aufbauen wollen Unterstützt Unternehmen bei der Frage, ob und wann sie migrieren und wo sie konkret beginnen sollten Befasst sich mit der Integration und Migration von Legacy-Systemen und der Kommunikation mit diesen Systemen Stellt Migrationspattern vor und beschreibt, wo und wie sie am besten eingesetzt werden Bietet Beispiele für die Datenbankmigration und begleitende Synchronisationsstrategien Beschreibt das Zerlegen von Anwendungen einschließlich einer Reihe von Refaktorisierungspattern
