A Developer's Guide to Blockchain Programming Fundamentals Blockchain development is entering a period of explosive growth, as real applications gain traction throughout multiple industries and cryptocurrencies earn greater acceptance throughout the financial sector. Blockchain represents one of the most promising opportunities for developers to advance and succeed. Building Blockchain Apps is an accessible guide to today’s most advanced and robust blockchain programming models and architectures. Building on his pioneering experience, Michael Juntao Yuan covers a wide range of blockchain application development paradigms. The book starts with a concise introduction to blockchain and smart contract technologies. It then guides you through application development on Ethereum-compatible smart contract platforms. Ethereum is the largest and most robust blockchain ecosystem in the world. Coverage includes Ethereum topics such as tools, application frameworks, internal data structures, external data interfaces, and future roadmap An introduction to new blockchain data protocol based on ElasticSearch, which provides insights into the current state of smart contracts and enables new application designs How to build an application-specific smart contract protocol by modifying and customizing the open source Ethereum Virtual Machine and its programming language tools How to extend and support language features that are most suitable for particular kinds of smart contracts (e.g., smart contracts for e-commerce marketplaces) with the open source Lity project How to customize and change the blockchain consensus layer beneath the application layer via the popular Tendermint and Cosmos SDK frameworks A survey of cryptocurrency and financial topics from the developers’ point of view, providing an analytical framework for valuating cryptocurrencies and explaining the roles of crypto exchanges Register your book for convenient access to downloads, updates, and/or corrections as they become available.

Nokia's smartphones pack a powerful computer into a very small space. Unlike your desktop or laptop, your smallest computer can be connected to the Internet all the time, and can interact with the world around it through its camera, voice recognition, and its traditional phone keypad. Nokia smartphones combine these features with impressive storage options and a host of networking protocols that make this smallest computer the only thing a road warrior truly needs. If you're still cracking open your laptop or pining for your desktop while you're on the road, you haven't begun to unlock your Nokia's full potential. Nokia Smartphone Hacks is dedicated to tricking out your smartphone and finding all the capabilities lurking under the surface. Learn how to: Unlock your phone so that you can use it with any carrier Avoid and recover from malicious mobile software Watch DVD movies on the phone Use the phone as a remote control Use the phone as a data modem for your notebook Check your email and browse the web Post to your weblog from your phone Record phone conversations Choose mobile service plans Transfer files between the phone and your computer Whether you want to use your smartphone as your lifeline while you're on the road, or you're just looking for a way to make the most of the time you spend waiting in lines, you'll find all the user-friendly tips, tools, and tricks you need to become massively productive with your Nokia smartphone. With Nokia Smartphone Hacks, you'll unleash the full power of that computer that's sitting in your pocket, purse, or backpack.

Fully Updated to Cover Major Enhancements to Seam 2.x In Seam Framework, Second Edition, the authors of the leading guide to Seam programming have systematically updated their text to reflect the major improvements introduced with Seam 2.x. This author team–all key Seam project contributors–teach Seam 2.x through detailed example applications that reveal how Seam simplifies many tasks that were previously difficult or impractical. Their robust descriptions are complemented by in-depth feature discussions that demonstrate how to use Seam’s power to the fullest. Whether you’re new to Seam programming or a seasoned Seam developer who wants to achieve deeper mastery of Seam 2.x, this book will be an indispensable resource. Coverage includes Using improvements to Seam’s conversation model, transaction management, and other features Enhancing security, performing end-to-end validation, and providing custom exception pages Using Quartz to execute timer jobs in your application Generating bookmarkable RESTful Web pages the easy way Developing highly scalable applications with Seam 2.x’s new multilayer caching Simplifying development with Groovy, the scripting language that runs directly on the JVM Using jBPM business processes to improve page flow Previewing Web Beans (JSR-299), the future core of Seam that will transform Java EE Web development *Download source code for this book’s case study application at solutionsfit.com/seam.
A new edition of this title is available, ISBN-10: 0137129394 ISBN-13: 9780137129393 Discover JBoss Seam: the Unified Framework for Simpler, More Powerful Web Development JBoss Seam integrates EJB 3.0 and JSF components under a unified framework that simplifies and accelerates Java EE web development. Now, JBoss Seam’s project leader and technology evangelist take you inside this powerful new technology, showing exactly how to put it to work. Michael Yuan and Thomas Heute show how JBoss Seam enables you to create web applications that would have been difficult or impossible with previous Java frameworks. Through hands-on examples and a complete case study application, you’ll learn how to leverage JBoss Seam’s breakthrough state management capabilities; integrate business processes and rules; use AJAX with Seam; and deploy your application into production, one step at a time. Coverage includes How JBoss Seam builds on–and goes beyond–the Java EE platform • Using the “Stateful Framework”: conversations, workspaces, concurrent conversations, and transactions • Integrating the web and data components: validation, clickable data tables, and bookmarkable web pages • Creating AJAX and custom UI components, enabling AJAX for existing JSF components, and JavaScript integration via Seam Remoting • Managing business processes, defining stateful pageflows, and implementing rule-based security • Testing and optimizing JBoss Seam applications • Deploying in diverse environments: with Tomcat, with production databases, in clusters, without EJB 3, and more
