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.

This practical guide shows you how to make your Java web applications more responsive and dynamic by incorporating new Ajaxian features, including suggestion lists, drag-and-drop, and more. Java developers can choose between many different ways of incorporating Ajax, from building JavaScript into your applications "by hand" to using the new Google Web Toolkit (GWT). "Ajax on Java" starts with an introduction to Ajax, showing you how to write some basic applications that use client-side JavaScript to request information from a Java servlet and display it without doing a full page reload. It also presents several strategies for communicating between the client and the server, including sending raw data, and using XML or JSON (JavaScript Object Notation) for sending more complex collections of data. The book then branches out into different approaches for incorporating Ajax, which include: the Prototype and script.aculo.us Javascript libraries, the Dojo and Rico libraries, and DWR; integrating Ajax into Java ServerPages (JSP) applications; using Ajax with Struts; integrating Ajax into Java ServerFaces (JSF) applications; and, using Google's GWT, which offers a pure Java approach to developing web applications: your client-side components are written in Java, and compiled into HTML and JavaScript. Ajax gives web developers the ability to build applications that are more interactive, more dynamic, more exciting and enjoyable for your users. If you're a Java developer and haven't tried Ajax, but would like to get started, this book is essential. Your users will be grateful.

"Java and XML, 3rd Edition", shows you how to cut through all the hype about XML and put it to work. It teaches you how to use the APIs, tools, and tricks of XML to build real-world applications. The result is a new approach to managing information that touches everything from configuration files to web sites. After two chapters on XML basics, including XPath, XSL, DTDs, and XML Schema, the rest of the book focuses on using XML from your Java applications. This third edition of "Java and XML" covers all major Java XML processing libraries, including full coverage of the SAX, DOM, StAX, JDOM, and dom4j APIs as well as the latest version of the Java API for XML Processing (JAXP) and Java Architecture for XML Binding (JAXB). The chapters on web technology have been entirely rewritten to focus on the today's most relevant topics: syndicating content with RSS and creating Web 2.0 applications. You'll learn how to create, read, and modify RSS feeds for syndicated content and use XML to power the next generation of websites with Ajax and Adobe Flash. It includes topics such as: the basics of XML, including DTDs, namespaces, XML Schema, XPath, and Transformations; the SAX API, including all handlers, filters, and writers; the DOM API, including DOM Level 2, Level 3, and the DOM HTML module; the JDOM API, including the core and a look at XPath support; the StAX API, including StAX factories, producing documents and XMLPull; Data Binding with JAXB, using the new JAXB 2.0 annotations; Web syndication and podcasting with RSS; and, XML on the Presentation Layer, paying attention to Ajax and Flash applications. If you are developing with Java and need to use XML, or think that you will be in the future; if you're involved in the new peer-to-peer movement, messaging, or web services; or if you're developing software for electronic commerce, "Java and XML" will be an indispensable companion.

You'll follow a fictional company throughout the book to learn how building a microservice architecture affects a single domain.

All of Java's Input/Output (I/O) facilities are based on streams, which provide simple ways to read and write data of different types. Java provides many different kinds of streams, each with its own application. The universe of streams is divided into four large categories: input streams and output streams, for reading and writing binary data; and readers and writers, for reading and writing textual (character) data. You're almost certainly familiar with the basic kinds of streams--but did you know that there's a CipherInputStream for reading encrypted data? And a ZipOutputStream for automatically compressing data? Do you know how to use buffered streams effectively to make your I/O operations more efficient? Java I/O, 2nd Edition has been updated for Java 5.0 APIs and tells you all you ever need to know about streams--and probably more. A discussion of I/O wouldn't be complete without treatment of character sets and formatting. Java supports the Unicode standard, which provides definitions for the character sets of most written languages. Consequently, Java is the first programming language that lets you do I/O in virtually any language. Java also provides a sophisticated model for formatting textual and numeric data. Java I/O, 2nd Edition shows you how to control number formatting, use characters aside from the standard (but outdated) ASCII character set, and get a head start on writing truly multilingual software. Java I/O, 2nd Edition includes: * Coverage of all I/O classes and related classes * In-depth coverage of Java's number formatting facilities and its support for international character sets
