GLOBALE PROVINZ
Zu Beginn der 2020er-Jahre hat die digitale Transformation unseren Alltag und fast alle Bereiche von Wirtschaft und Verwaltung erreicht. Die Informationsgesellschaft ist eine selbstverständliche Realität geworden. Die sozio-ökonomische Bedeutung der Internet-basierten Systeme und der »Elektronengehirne« ist vergleichbar mit der Bedeutung der großen Entdeckungen der Renaissancezeit und anderen epochalen Entwicklungen wie der Weltraumfahrt, der Nutzung der Atomenergie, oder auch den Erfindungen von Eisenbahn und Automobil.Dieser Bericht vom Werden unserer Informationsgesellschaft basiert auf den Erinnerungen eines Vertreters der »Generation X«, die erlebt hat, wie in circa 40 Jahren das private, berufliche und öffentliche Leben vom Gebrauch des sogenannten »Netzes« und der Mensch-Maschine-Symbiose immer mehr – sowohl positiv als auch negativ – geprägt wurde. Georg Rainer Hofmann, einer der Aktivisten dieser Entwicklung in Deutschland, zeichnet in einem komplexen Bild die technischen, ökomischen, sozio-politischen, und auch ethisch-philosophischen Hintergründe und Herausforderungen. Ein wichtiger Beitrag zur Geschichte unserer digitalen Welt.Mit einem Geleitwort von Alexander Rabe und mit Beiträgen von: Wolfgang Alm, Bernd Becker, Christof Blum, Ralf Cordes, Peter Egloff, José Luis Encarnação, Lucia Falkenberg, Andreas Hufgard, Andreas Kindt, Richard Knapp, Günter Koch, Detlef Krömker, Guerino Mazzola, Radu Popescu-Zeletin, Olaf Reubold, Gerd Rossbach, Gerd Schürmann, Hans-Georg Stark, Harald Summa, Rainer Thome, Thomas Wolf, Ruben Zimmermann.Der Informatiker und Ökonom Prof. Dr. Georg Rainer Hofmann (geb. 1961) ist Professor und Direktor des Information Management Instituts (IMI) an der Technischen Hochschule in Aschaffenburg. Er hat viele Entwicklungen der Informationsgesellschaft selbst erleben und daran mitwirken dürfen. Seine mit dem Zeitgeist verflochtenen Erinnerungen umfassen circa 40 Jahre voller richtungsweisender Erkenntnis- und Technikfortschritte, aber auch voller Zu-, Glücks- und Problemfälle des allmählich-plötzlichen Digitalen Wandels. Er erzählt von richtungsweisenden Ereignissen und von Begegnungen mit prägenden Personen, von denen sich einige auch selbst zu Wort melden. Viele von ihnen wären sicher Nobelpreisträger geworden – gäbe es einen »Nobelpreis für Digitalwissenschaften«

Diagnosis and Fault-tolerant Control Volume 2
This book presents recent advances in fault diagnosis and fault-tolerant control of dynamic processes. Its impetus derives from the need for an overview of the challenges of the fault diagnosis technique and sustainable control, especially for those demanding systems that require reliability, availability, maintainability, and safety to ensure efficient operations. Moreover, the need for a high degree of tolerance with respect to possible faults represents a further key point, primarily for complex systems, as modeling and control are inherently challenging, and maintenance is both expensive and safety-critical.Diagnosis and Fault-tolerant Control 2 also presents and compares different fault diagnosis and fault-tolerant schemes, using well established, innovative strategies for modeling the behavior of the dynamic process under investigation. An updated treatise of diagnosis and fault-tolerant control is addressed with the use of essential and advanced methods including signal-based, model-based and data-driven techniques. Another key feature is the application of these methods for dealing with robustness and reliability. VICENC PUIG is Professor of Automatic Control at the Universitat Politècnica de Catalunya (UPC), Spain. He has published more than 80 journal articles and more than 350 articles in international conference/workshop proceedings related to diagnosis and faulttolerant control.SILVIO SIMANI is Professor of Automatic Control in the Engineering Department of Ferrara University, Italy. He has published about 260 journal and conference papers, several book chapters and four monographs on fault diagnosis and sustainable control topics.CHAPTER 1 NONLINEAR METHODS FOR FAULT DIAGNOSIS 1Silvio Simani and Paolo Castaldi1.1.

Diagnosis and Fault-tolerant Control 1
This book presents recent advances in fault diagnosis strategies for complex dynamic systems. Its impetus derives from the need for an overview of the challenges of the fault diagnosis technique, especially for those demanding systems that require reliability, availability, maintainability and safety to ensure efficient operations. Moreover, the need for a high degree of tolerance with respect to possible faults represents a further key point, primarily for complex systems, as modeling and control are inherently challenging, and maintenance is both expensive and safety-critical.Diagnosis and Fault-tolerant Control 1 also presents and compares different diagnosis schemes using established case studies that are widely used in related literature. The main features of this book regard the analysis, design and implementation of proper solutions for the problems of fault diagnosis in safety critical systems. The design of the considered solutions involves robust data-driven, model-based approaches. VICENC PUIG is Professor of Automatic Control at the Universitat Politècnica de Catalunya (UPC), Spain. He has published more than 80 journal articles and more than 350 articles in international conference/workshop proceedings related to diagnosis and faulttolerant control.SILVIO SIMANI is Professor of Automatic Control in the Engineering Department of Ferrara University, Italy. He has published about 260 journal and conference papers, several book chapters and four monographs on fault diagnosis and sustainable control topics.Introduction ixVicenç Puig and Silvio SimaniCHAPTER 1 MATHEMATICAL MODELING AND FAULT DESCRIPTION 1Silvio Simani1.1.

Modularizing Legacy Projects Using TDD
Improve current or new projects with top notch testability and maintainability. Writing tests improves the design of your apps, as it pushes you to have a more modularized design. This in turn improves the maintainability and sustainability of your apps. This book is for iOS developers who already know the basics of iOS and Swift development but want to learn all the testing pro features in iOS.You'll start by reviewing the TDD Cycle and how to implement these concepts on a legacy project or a new one. You'll then walk through TDD step-by-step on a blank project, including setting up test targets, assertions, and expectations. You'll follow that with all levels of testing such as unit tests, integration tests, and end-to-end tests, and also tackle fairly complex, yet badly written legacy code.The book will take you through the journey of modularizing a legacy app using TDD. Throughout this journey, you will be introduced to multiple testing concepts and techniques, like writing tests for network and core data layers. You will write tests to ensure the thread safety of your app. And you’ll add a new feature while you are in the middle of refactoring, which is an important skill so you can keep adding features while you are fixing your technical debt. By the end of this book, you will have all the tools needed to become a testing master.WHAT YOU'LL LEARN* Use mocking and dependency injection to make components more testable* Write tests for asynchronous code like network code* Add new features to existing legacy apps using TDDWHO THIS BOOK IS FORExperienced iOS developers who care about software quality and meeting customer expectations.

macOS Daemonology
Take advantage of the full power of Swift through XPC. Development for macOS differs from iOS and web-based development because of multicomponent applications. Besides the usual GUI-based applications and app extensions, there are a wide range of daemons—processes that run in the background—to worry about. These include system monitoring, event listening, notification agents, and many-many more.First, you'll take a tour around different types of daemons: user agents, privileged helpers, login items, XPC services, and System Extensions. Knowing key specifics of the daemons will open a wide range of possibilities from non-trivial application development to system development. You'll find lots of examples, working code samples, and even ready-to-use utilities. The book will guide you step-by-step through preparation, registration, and management of all kinds of daemons.System Extensions are brand new for macOS and open additional powerful features for developers. You'll explore installation, user flow, and communication with System Extensions, too, with examples, of course. XPC provides an object-oriented way of communication. There’s no need for custom byte/text-based protocols. A good macOS developer has to know not only programming interfaces, but also design patterns related to technology. XPC communication has a few patterns of its own, and we'll go through them all, including uni- and bi-directional communication, passing objects by-value and by-proxy, handling connection invalidation, named and anonymous connections, and many more.WHAT YOU'LL LEARN* Use multiples types of daemons in your applications* Deal with System Extensions – the new type of system daemons* Get acquainted with Swift bridging patterns for XPC communicationWHO THIS BOOK IS FORSoftware developers and solution architects with at least a working knowledge of macOS and Swift programming. As overview, may be interested for software/solution architects.VOLODYMYR VASHURKIN (@ALKENSO) is an experienced macOS system and security developer and engineer. His first steps in daemonology were made while researching FileVault full disk encryption on macOS, and its interaction with iCloud services. iCloud on macOS uses plenty of system daemons and user agents, and investigating macOS’s infrastructure led to a solid understanding of how the background world of macOS works. This led him deeply into the development of security solutions for macOS. Working in the security area, Volodymyr gained practical skills for creating GUI-based applications with fewer user agents (user background processes) and root daemons (root'ed background processes). In developing his knowledge and skills, Volodymyr faced numerous tricky cases, lack of documentation, and minor and major documentation gaffes. He would like to help his readers avoid the same pitfalls. PART 1. DAEMONS: OVERVIEW & MANAGEMENTCHAPTER 1.
