Beginning Google Web Toolkit: From Novice to Professional
ISBN: , SKU: , AUTHOR: Smeets, Bram / Boness, Uri / Bankras, Roald, PUBLISHER: Apress, The open source, lightweight Google Web Toolkit (GWT) is a framework that allows Java developers to build Rich Internet Applications (RIA), more recently called Ajax applications, in Java. Typically, writing these applications requires a lot of JavaScript development. However, Java and JavaScript are very distinctively different languages (although the name suggests otherwise), therefore requiring a different development process. In Beginning Google Web Toolkit: From Novice to Professional, you'll learn to build rich, user-friendly web applications using a popular Java-based Ajax web framework, the Google Web Toolkit. The authors will guide you through the complete development of a GWT front end application with a no-nonsense, down-to-earth approach. You'll start with the first steps of working with GWT and learn to understand the concepts and consequences of building this kind of application. During the course of the book, all the key aspects of GWT are tackled pragmatically, as you're using them to build a real-world sample application. Unlike many other books, the inner workings of GWT and other unnecessary details are shelved, so you can focus on the stuff that really matters when developing GWT applications. What you'll learn Get a solid foundation to develop RIAs. Understand the basics of the GWT Framework and its components. Fit GWT into your application's life cycle and development process. Develop rich web front-end GUIs using widgets, composite widgets, panels, and much more. Integrate with RPC, and various other data formats. Reinforce principles learned throughout the book by working through a real-world sample application created with GWT from scratch. Who is this book for? Beginning Google Web Toolkit: From Novice to Professional is written for Java developers of all levels who want to start building Rich Internet Applications. The book assumes no prior knowledge of developing Ajax applications and/or working with JavaScript. About the Apress Beginning Series The Beginning series from Apress is the right choice to get the information you need to land that crucial entry-level job. These books will teach you a standard and important technology from the ground up because they are explicitly designed to take you from "novice to professional." You'll start your journey by seeing what you need to know--but without needless theory and filler. You'll build your skill set by learning how to put together real-world projects step by step. So whether your goal is your next career challenge or a new learning opportunity, the Beginning series from Apress will take you there--it is your trusted guide through unfamiliar territory
Sirui Treppiedi S--N carbonio 5 sezioni SN
Sirui',s S--N Carbon Fiber Tripod weighs 2.6 lb and yet can support up to 26.4 lb. The S--N has individual leg spreading capability for low angles or uneven terrain. Besides the standard center column a short center column is included which allows the tripod to get down to 7". One of the legs is removable to convert to a monopod. When folded, the tripod is 17.7" long, and only 1.6" thick. 8 Layers of Carbon Fiber for Superior Load CapacityThe use of 100% carbon fiber and 8 cross pattern layers makes Sirui tripods and monopods capable of supporting impressive load capacities, while providing a lightweight product. In addition to providing high strength and low weight, carbon fiber is also highly resistant to temperature changes, friction (no need for lubrication) and corrosion.Custom Anodized Surface TreatmentAll Sirui products undergo a special anodized surface treatment that makes any metal surfaces highly resistant to wear and increases durability and weather resistance. Anodizing is an environmentally safe electrochemical process. This also prepares the surface to provide better adhesion of colored finishes.Temperature Tolerance TestPhotographers often work in extreme environments, like blazing deserts or sub-zero mountaintops. It is vital that your equipment works under these conditions. That is why all of these products are "torture-tested" under conditions that far exceed what most people will ever experience: -F (-C).Certified Longevity Tests for Quality and ReliabilityTo confirm the quality and reliability of Sirui tripods (and dedication to details), an independent testing lab (SGS) subjected the leg angle lock spring mechanisms to exhaustive longevity tests. The test reports show that even after actuations, the springs continued to perform perfectly.Short Center ColumnAllows low angle shooting for unique perspectives and macro photography.Precision Leg TubesThe difference in diameter of leg tubes is only 3.0mm from tube to retracted tube. Thanks to precision manufacturing, the legs open and close easily, while the small diameter difference provides added leg stability.Half-turn Leg LocksTo lock the legs of Sirui tripods/monopods, twisting locks are utilized for maximum reliability and stability. Simply twist the rubber leg locks 1/2 turn and the legs will extend by themselves.Unique Locking SystemThe Sirui S-N series tripods have a unique leg position locking system that clicks in place when the tripod is opened. This guarantees that the tripod legs will be properly positioned -providing a rugged, stable support for your equipment. Simply open the tripod in the direction of the arrows until it clicks into place. When you',re done shooting, press the red unlock button and close the tripod flat.Non-Twist Center Column/LegsAll Sirui center columns and legs have keyed, grooved channels that prevent twisting, providing additional stability and safety for your photographic equipment.Converts to MonopodThe detachable leg lets you transform your tripod into a monopod, this reduces the amount of equipment you need to carry and makes your camera bag or backpack lighter.

Sirui Treppiedi S--N carbonio 4 sezioni SN
Sirui',s S--N Carbon Fiber Tripod is a complete departure from the old days of "lugging around" a heavy metal tripod. To begin with, it only weighs 2.2 lb and yet can support up to 26.4 lb. The S--N is so versatile in its adjustments that it does about anything you can think of short of bending. It has individual leg spreading capability for low angles or uneven terrain. Besides the standard center column a short center column is included which allows the tripod to squat way down. And it reverses for even lower perspectives. The icing on the cake is a removable leg that converts to a monopod. And when the shoot is over the S--N won',t take up much space either. It folds flat to a mere 1.6" thick. 8 Layers of Carbon Fiber for Superior Load CapacitySirui is one of the few manufacturers who make their own carbon fiber leg tubes. The use of 100% carbon fiber and 8 cross pattern layers makes Sirui tripods and monopods capable of supporting impressive load capacities, while providing a lightweight product. In addition to providing high strength and low weight, carbon fiber is also highly resistant to temperature changes, friction (no need for lubrication) and corrosion.Custom Anodized Surface TreatmentAll Sirui products undergo a special anodized surface treatment that makes any metal surfaces highly resistant to wear and increases durability and weather resistance.
