Das Buch beschreibt diese Entwicklungen, ihre moglichen wirtschaftlichen und gesellschaftlichen Folgen sowie ihre Auswirkungen auf das Weltbild und das Selbstbild der Menschen und es analysiert die Moglichkeiten, diese Entwicklungen gestaltend zu beeinflussen."

Have you ever felt frustrated working with someone else's code? Difficult-to-maintain source code is a big problem in software development today, leading to costly delays and defects. Be part of the solution. With this practical book, you'll learn 10 easy-to-follow guidelines for delivering Java software that's easy to maintain and adapt. These guidelines have been derived from analyzing hundreds of real-world systems. Written by consultants from the Software Improvement Group (SIG), this book provides clear and concise explanations, with advice for turning the guidelines into practice. Examples for this edition are written in Java, while our companion C# book provides workable examples in that language. Write short units of code: limit the length of methods and constructors Write simple units of code: limit the number of branch points per method Write code once, rather than risk copying buggy code Keep unit interfaces small by extracting parameters into objects Separate concerns to avoid building large classes Couple architecture components loosely Balance the number and size of top-level components in your code Keep your codebase as small as possible Automate tests for your codebase Write clean code, avoiding "code smells" that indicate deeper problems

Das Buch spielt mit einem neuen, ganzheitlichen Vorstellungsbild des Menschen, der aus drei Einheiten zusammengesetzt gedacht wird: das analytische Denken residiert in einer computerahnlichen linken Gehirnhalfte, die kreative Intuition sitzt wie ein naturbelassenes neuronales Netzwerk in der rechten. Der Mensch denkt, wohin ihn das dritte System lenkt: Ein hyperschneller Anzeichen-Identifizierer alarmiert etwa bei gefahrlichen Ereignissen die Aufmerksamkeit, unbewusst, ohne Denken. Bis auf ein paar Zeilen mathematischer Erklarung ist dieses Buch fulminante Philosophie. Wichtige Ansichten dieser Welt werden gedreht und bleiben zum Teil auf dem Kopf stehen. Die Lehren von Platon, Aristoteles, Konfuzius, Epikur, Freud & Co. erscheinen als notwendige Philosophien verschiedener Gehirnnutzungsvarianten. Das Buch ist eine scharfsinnig-bissig-humorvolle und sehr personliche Auseinandersetzung mit dem, was wir "Lebenssinn" nennen.

One of the most useful features of today's modern browsers is the ability to store data right on the user's computer or mobile device. Even as more people move toward the cloud, client-side storage can still save web developers a lot of time and money, if you do it right. This hands-on guide demonstrates several storage APIs in action. You'll learn how and when to use them, their plusses and minuses, and steps for implementing one or more of them in your application. Ideal for experienced web developers familiar with JavaScript, this book also introduces several open source libraries that make storage APIs easier to work with. Learn how different browsers support each client-side storage API Work with web (aka local) storage for simple things like lists or preferences Use IndexedDB to store nearly anything you want on the user's browser Learn how support web apps that still use the discontinued Web SQL Database API Explore Lockr, Dexie, and localForage, three libraries that simplify the use of storage APIs Build a simple working application that makes use of several storage techniques

Eingebettete Systeme begegnen uns mittlerweile uberall im Alltag: vom Mikrocontroller in der Waschmaschine bis hin zum leistungsfahigen DSP im Autoradio. Noch vor wenigen Jahren wurden diese Prozessoren aufwandig in Assembler programmiert und besassen nur in den wenigsten Fallen ein Betriebssystem. Mittlerweile aber bieten leistungsfahige und schlanke Linux-Derivate auch auf einfachen Prozessoren den Komfort der Schnittstellentreiber, des Multi-Threadings und eines Dateisystems. Die vorgestellte Hardware ist teilweise Konsumerprodukten entlehnt und somit gut erhaltlich.

Besonderer Wert wird auf die Praxistauglichkeit der Implementierungen gelegt, und so sind die Beispiele zur Hardwareanbindung via I2C, zur Kommunikation und zur Bildverarbeitung vollstandig durchimplementiert und online frei verfugbar. Das vorliegende Buch richtet sich an Berufsanfanger, Praktiker und Studenten der Informatik und der Ingenieurswissenschaften.

"Drag and Drop" is a series of 12 books, mainly aimed at beginners and students. It is based on the WYSIWYG (what you see is what you get) method, so the reader can easily correlate what is written in the book with what is displayed on the computer screen. The programs can be learnt by the simple process of dragging, dropping and clicking on the command with the mouse. Each book in the series focuses on a particular software and explains it in a clear and concise manner.

With traditional software unit tests, there's never a guarantee that an application will actually function correctly in the production environment. When you add microservices, testing becomes even more tricky. Testing Java Microservices teaches readers how to write tests like unit, component, integration, container, contract, chaos, and more. Along the way, it also covers technologies like the Arquillian ecosystem, Wiremock, Mockito, AssertJ, Pact or Gatling. Finally, the book demonstrates how everything fits together into the Continuous Delivery pipeline. Key Features: * Practical hands-on guide * Writing Persistence tests * Teaches test strategies * Shows how everything fits together in the Continuous Delivery Pipeline Readers should be comfortable programming in Java. Experience with testing tools like jUnit is helpful but not required. Some experience in Java EE, Spring and Docker is also helpful. About the Technology: A microservice may consist of several, several hundred, or even several thousand of lines of code. Microservices enable programmers to isolate and scale smaller pieces of an application, rather than the entire application.
