Recently, I read Why Big Data Projects Fail by Stephen Brobst. I can’t agree more with his opinions which exposed the problem I’ve been worried about. In this article, I am going to further discuss this topic to remind the enterprises to beware of falling into such pitfall of failure. Let’s have a look on a positive example. As a successful enterprise in leveraging big data, how does Google make...

In Java development, we may encounter the complex set operations. Java alone is not powerful enough to save programmers’ efforts in implementing the computation details, which is time-consuming and poor in code reuse. In view of this, programmers usually resort to dynamic calculation script for set operation. SQL is surely the first kind of script that comes into most programmers’ mind. However,...

Sebastiano Armeli-Battana is the author of the successful 'MVC Applies to JavaScript' eBook. We thought we'd get to know a little more about the author! 1. For someone that’s new to the JavaScript sector, can you explain why they should use MVC? I would say that a JS noob should use MVC, just because it’s widely spread pattern used across different programming languages. I think they would enjoy...

The Cassandra's data base is a NOSQL column family's oriented, is a data base made to work of high performance, scalability and fault tolerant. In your new version, it gets some improvements like Cassandra Query Language third version, CQL 3.0 with storage with collections and key complex. With improvements in Cassandra, there is a one problem: How do I use all potential of the Cassandra...

The Browser Binding with a CMIS Repository By Florian Müller, Jay Brown, and Jeff Potts, authors of CMIS and Apache Chemistry in Action A big part of the CMIS specification describes how the CMIS domain model is mapped to the bytes that are transferred. These mappings are called bindings. CMIS 1.0 defines two bindings, the Web Services...

How did you first get into developing / coding? My first encounter with a computer was in 1987 during a physics class. This particular one (a Commodore C64) went immediately to my Xmas wish list. When I teared away the gift wrapping, I found the datasette broken. A datasette was a tape drive using audio cassettes for storage – without it, there were no chance to play any of the bundled games;...

As a developer, when you are building and/or designing a Java application; the first (or one of the first) question you might ask is... "What are the objects?" This seems to be a very simple question. But it is not. There probably is no single "right" answer to this question. Nevertheless, careful consideration given to this question will contribute to a good start to one's Java development...

When we started building our first Java application, at my company Amway Corp, many years ago; we learned our first lesson. In spite of all the formal training we received, in spite of all the literature at our disposal; we still needed help with our Java development on a regular basis. Where would this assistance come from? At the time, we had no in-house Java subject-matter experts. What we...

Learning Java (or any programming language) can be a great challenge. Any group of developers, learning Java, will bring with them a variety of backgrounds and experiences. In our case, our first Java project began with developers that had COBOL language experience. Our second Java project, began with developers that had RPG language experience. Even though COBOL and RPG don't "look" like Java,...

Expression Language (EL) was first introduced as part of JSTL 1.0, was then moved JSP 2.0 and was unified with JSF 1.2 in JSP 2.1. In Java EE 7, EL is a new separate JSR, JSR 341. Many new features are introduced in EL 3.0. This blog shows how to use new following new features of EL 3.0: Standalone environment Lambda expression (section 1.20 of EL 3.0 spec) The new operator ; to separate...

Most voters in the just-completed Java.net poll on Java EE 7 believe that Java EE 7 will be the most widely used version of Java EE within the next few years. A total of 354 votes were cast in the poll, which ran for three weeks. The exact question and results were: How long will it be before Java EE 7 is the most widely used Java EE version? 14% (51 votes) - Less than 6 months 18% (65...

Over the last few years we've been busily writing the latest and greatest version of Magnolia. After all of this focus on new and (we hope) great, it seemed like time to focuse on something old and great. If you are old enough to remember the ZX Spectrum, the Commodore 64 or their various competitors, or if you like any kind of games, please keep on reading. You might have heard of the qaop...

Last week, I attended the global live launch of Java EE 7, a webcast I wrote about earlier, titled "Introducing Java EE 7." The live webcast happened twice (on at 17:00 GMT on June 12, and 12 hours later at 05:00 GMT on June 13), thus enabling every Java developer in the world to attend the live session at some point during non-sleeping hours. The value of attending the live sessions was...

Test Driven Development (TDD) has become a cornerstone of modern software craftsmanship. Behaviour Driven Development (BDD) takes it to the next level; it provides easier to use and a more readable syntax as well as many other improvements. If you haven't used Test Driven Development before, start with BDD, you will reap the benefits much faster. This book is a hands-on introduction on BDD. Using...

Open JDK

Java 8 will introduce (or introduces it depends if you have already played with the betas or not) a new full featured feature, lambdas. Instead of explaining the syntax, the semantics, how it's integrated with java.util, yada yada. Let's take an example and see how lambdas can be used by users and developers of APIs. Let suppose I want to design a JUnit/TestNG replacement, basically these two...
