* JSR-107, JCache: Alive and Going to be Part of Java EE 7: It seems that JCache will make it to Java EE 7 providing a standard caching mechanism for Java apps. This article discusses the benefits of using a caching mechanism, the major changes and advancements that have been made in the progress of JCache and the specification’s roadmap.
* How server-side performance affects mobile user experience: A short article providing an example of how to perform basic analysis of a mobile web site’s performance using the desktop and not the mobile. This way performance issues caused by slow server-side response times or non-optimized resource delivery can be found easily.
* Do You Really Get Memory?: A presentation where Jevgeni Kabanov creates a CPU model in Java in an attempt to explain the underlying mechanism of memory performance bottlenecks and the need for a correlated hardware, OS and JVM improvement. .
* How about distributed queues?: In this article, the GridGain approach to distributed queues is presented along with a simple showcase example. The idea is to enable developers to take well known data structures and distribute them over the grid..
* How to use Type safe dependency injection in Spring 3?: A short guide on how to achieve type safe dependency injection with Spring 3. Also check out The evolution of Spring dependency injection techniques and Spring configuration with zero XML.
* Functional thinking: Coupling and composition, Part 1: In this article the author discusses functional programming and shows how to refactor Java code in order to use a more functional approach via composition.
* Java Threads on Steroids: A Java Concurrency related article introducing the Disruptor framework and its underlying philosophy. The author argues that we can reduce the performance impact of context switching by forcing a thread or a process to run only on a specified set of CPUs, i.e. by leveraging processor affinity.
That’s all for this week. Stay tuned for more, here at JavaCodeGeeks.
Author David Gassner explores Java SE (Standard Edition), the language used to build mobile apps for Android devices, enterprise server applications, and more!
The course demonstrates how to install both Java and the Eclipse IDE and dives into the particulars of programming. The course also explains the fundamentals of Java, from creating simple variables, assigning values, and declaring methods to working with strings, arrays, and subclasses; reading and writing to text files; and implementing object oriented programming concepts. Exercise files are included with the course.
