For front-end web developers familiar with the basics of HTML, CSS, and JavaScript. Svelte and Sapper in Action is a comprehensive guide to building web apps with Svelte and Sapper. You'll dive straight into coding a complete travel packing app as you learn to write, compile, and organize Svelte components for your app's UI. From there, you'll master Svelte's awesome state management model and learn to use Sapper for simplified page routing, creating static sites, and providing offline support with Service Workers. By the time you're done, you'll be able to build web applications that are easier to understand, offer great UX, and don't compromise on SEO. Creating Svelte applications and components Communicating between Svelte components Routing between pages in both Svelte and Sapper Adding animation to components Debugging, testing, and deploying applications Implementing and invoking REST services in a Sapper app Exporting a Sapper app as a static site Imagine web apps with fast browser load times that also offer amazing developer productivity and require less code to create. That's what Svelte and Sapper deliver! Svelte pushes a lot of the work a frontend framework would handle to the compile step, so your app components come out as tight, well-organized JavaScript modules. Sapper is a lightweight web framework that minimizes application size through server-rendering front pages and only loading the JavaScript you need. The end result is more efficient apps with great UX and simplified state management. Rather than loading a framework like Angular, Vue, or React into the browser, Svelte compiles your components into tiny, well-organized JavaScript modules. That means your app loads lightning fast and runs even faster, in part because there's no need to load "just-in-case" framework code. Svelte also streamlines your UI development with a host of powerful features such as reactive statements, two-way data binding, stores, and context. The Sapper framework pairs perfectly with Svelte for efficient server-side rendering, code splitting, and API development.

Die Leistung von Computersystemen ist die ausschlaggebende Groe fur ihren Einsatz. Zur Messung der Leistung wird sehr oft das Benchmark-Verfahren als Standard-Tool eingesetzt, obwohl allgemein bekannt ist, dass die entsprechenden Ergebnisse nur eine sehr beschrankte Aussagekraft haben - dafur spricht naturlich ihre starke Orientierung an der Praxis. Modellbildende Techniken werden haufig zu Recht als "Mathematik-lastig" empfunden und suggerieren zudem eine Genauigkeit jenseits der Realitat. Dabei liegt es auf der Hand, dass beide Standpunkte sich erganzen und zusammen eine wesentlich bessere Messung, Analyse und Bewertung gestatten. Anhand dieser Konzeption erlautert der Autor bessere Methoden zur Leistungsbewertung von Computersystemen.

Creating Intelligent Content with Lightweight DITA documents the evolution of the Darwin Information Typing Architecture (DITA) - a widely used open standard for structuring technical content. DITA has grown in popularity and features since its origins as an internal grammar for structuring technical documentation at IBM. This book introduces Lightweight DITA (LwDITA, which should be read as "Lightweight DITA") as a proposed version of the DITA standard that reduces its dependence on complex Extensible Markup Language (XML) structures and simplifies its authoring experience. This volume aims to reconcile discrepancies and similarities in methods for authoring content in industry and academia and does so by reporting on DITA's evolution through the lens of computational thinking, which has been connected in scholarship and media to initiatives for learning to code and programming. Evia's core argument is that if technical communicators are trained with principles of rhetorical problem solving and computational thinking, they can create structured content in lightweight workflows with XML, HTML5, and Markdown designed to reduce the learning curve associated with DITA and similar authoring methodologies. At the same time, this book has the goal of making concepts of structured authoring and intelligent content easier to learn and teach in humanities-based writing and communication programs. This book is intended for practitioners and students interested in structured authoring or the DITA standard.

Das Management von Geschaftsprozessen ist seit einigen Jahren ein wichtiges - strumentarium der Unternehmensfuhrung. Dabei haben sich die im Laufe der Zeit entstandenen Konzepte und Ansatze kontinuierlich weiterentwickelt. Die effizi- te und effektive Schaffung neuer Produkte und Dienstleistungen als kreativer P- zess der Innovation ist ein uberlebenswichtiger Bestandteil der Unternehmensst- tegie. Die Informationstechnologie nimmt hier eine ambivalente Rolle ein, da sie einerseits Prozesseffizienz fordert, aber durch ihre Komplexitat oftmals den W- del erschwert. Neue Geschaftsmodelle und -konzepte erfordern flexible IT-Losungen und - wendungsarchitekturen, die sich den Geschaftsprozessen anpassen und nicht - gekehrt. Serviceorientierte Architekturen (SOA) stellen die Basis fur solche neue Losungen und Vorgehensweisen dar. Sie heben die bisher vorherrschenden, hart verdrahteten Verbindungen zwischen Systemen zu Gunsten einer flexiblen, leicht veranderbaren Architektur auf. Die vorgenommene Auflosung von Systemgrenzen ermoglicht eine starkere Verzahnung von Prozessen und Informationstechnologie. Diese enge Integration von Geschafts- und IT-Welt bietet Potenziale fur den - samten Business Process Lifecycle. Neben der Unterstutzung aller Transferschr- te, von der Design-, uber die Implementierungsphase bis hin zur konkreten A- fuhrung und der kontinuierlichen Kontrolle von Prozessen, eroffnet es auch die automatisierte Initiierung dieses Transfers. Die umfassende Automatisierung be- haltet weit reichende technologische und organisatorische Anderungen. Das - schaftsprozessmanagement der nachsten Generation wird neuartige Geschafts- delle in vielfaltiger Weise ermoglichen, ist aber zur erfolgreichen Umsetzung auf eine weitgehende automatisierte Transformation des Prozesswissens, und dabei insbesondere auf Processes to Applications" (P2A)-Mechanismen, angewiesen. Die technologischen Voraussetzungen fur diese nachste Generation der Geschaf- prozessumsetzung sind bereits geschaffen."
