In the blog post "Using Google's Protocol Buffers with Java," I quoted Josh Bloch's Third Edition of Effective Java, in which he wrote, "There is no reason to use Java serialization in any new system you write." Bloch recommends using "cross-platform structured-data representations" instead of Java's deserialization. In this article, we will demonstrate how fast and easy this can be done by leveraging two Java frameworks; Vaadin and Speedment. Because they both use Java Streams, it easy to connect them together. This means we will end up with a short, concise and type-safe application. | | Mega-Deal: Programming Courses from Only $10.99!

Apache Hadoop is an open-source software framework written in Java for distributed storage and distributed processing of very large data sets on computer clusters built from commodity hardware. All the modules in Hadoop are designed with a fundamental assumption that hardware failures are common and should be automatically handled by the framework. Hadoop has become the de-facto tool used for Distributed computing.
 Getting Started with Mobile Application Testing
You're thinking of building a mobile app or perhaps you've already built one; depending on the approach you've taken, it could be a web app1, a native app2, or both. Mobile devices complicate testing further. An app that runs on one device might not run as expected on another, even if both devices are running the same operating system (OS) or OS version. As with desktop browsers, mobile browsers are implemented differently across mobile devices or mobile device OS, so there's no guarantee that what runs on one device will work the same on another. | | Your Suggestions
