Java User Groups
During the recent JavaOne conference, I was able to share how developers can put their Java codes up a notch by using functional programming and clean coding practices.
Earlier this October, I was given the privilege of speaking at JavaOne regarding the fusion of contemporary Continuous Delivery processes and practices with the established and widely-accepted Maven release process.
BDD is a communication and collaboration process that aims to deliver what is only value-adding to the business. It is a process of establishing a common language between the business stakeholders and the development team to come with a consensus of the value that needs to be answered by the software.
If you want to learn how to write effective tests and better your code, produce high quality applications, know the latest on agile development tools and practices, and ultimately become a Java master, then this workshop is for you.

Has been 1 year, after the Oracle vs Google saga, and I hear there will be appeal.. I am personally dunno what is appeal mean, i know sex appeal. huahua.. yes, I try to learn another tech and dedicate my time less to Java, touching NodeJS, try-ing Cloud, and yes, spending my time to my old hobbyes far become computer came to my life, fish tropical breeding.
I live in emerging country, which...

Much of my Tuesday at JavaOne 2012 was spent thinking about questions to ask the people I was going to interview, conducting the interviews, and trying to set up interviews for Wednesday. Late in the afternoon I attended the 2012 Duke's Choice Award Winners JavaOne BOF session, followed by the Duke's Choice Award Winners dinner. Today I interviewed...
Oracle just give free ADF Essential on Glassfish, a streamline edition of ADF. An interesting thing is there are also OEPE (Oracle Eclipse Plugins) that have ADF inside. which the Jdeveloper edition is far more complete and rich. www.oracle.com/technetwork/developer-tools/adf
ADF Essential is free for glassfish deployment, and with support US$ 1250/server (/core??), and you will get the source....

The Bucharest Java User Group is up and running in Bucharest, Romania! The JUG held its fourth meeting (see picture) on August 23. The group's first meeting was held on May 24. In a message to the Java.net JUG Leaders email list, Bucharest JUG leader Ioan Eugen Stan noted...
10 years ago, we began our journey into the world of Java and "J2EE".
It was a big risk for my company, Amway Corp, to do this.
We had no in-house expertise and we had critical applications to migrate to the new technology.
From the beginning, we were determined to succeed.
Today, 10 years after; I can say our Java adventure has been very successful.
We have created two complex applications and...
A few years ago, we met with our business analysts to discuss security for our application.
Our goal was to implement our own authentication mechanism for the web-based or user-interface
portion of the application.
We defined authentication security as "access rights to resources of the application".
After some initial discussion, one of our business analysts suggested we look for an
When my company, Amway Corp, makes a sale; somewhere, somehow a computerized transaction of that sale is created.
This transaction is sent to a number of applications at Amway for processing.
One such destination is our Java application.
We created a capability, called the Transaction Monitor (or TM) to deliver transactions to our app.
Our initial version of the TM worked well, but it was still...
We began creating our second Java application five years after we began the first app.
We were hoping the second application would give us a chance to use additional Java technologies.
We began by gathering all of the known functional requirements and matched them to the various
Java-related technologies we knew of.
The result was a high-level technical architecture of the application.

Searching at Scale
by Trey Grainger and Timothy Potter, authors of Solr in Action
One of the most appealing aspects of Solr, beyond its speed, relevancy, and powerful text searching features, is how well it scales. In this article, based on chapter 3 of Solr in Action, the authors explain how Solr is able to scale to handle billions of documents while still maintaining lightning-fast search...
ScalaTest is a xUnit style testing framework. An actor is an object that can be reached through an address, processes messages from a mailbox and sends messages to other actors using the same type of addresses. An actor encapsulates state; it does not share this state with anyone. An actor has behavior, it does something specific with the messages it receives. This article, based on a portion of chapter 2 from Akka in Action, shows how to test actors and send one-way messages.
Bigtable systems are important NoSQL data architecture patterns because they can quickly scale to manage large data volumes. They are also known to be closely tied with many MapReduce systems. In this article from Making Sense of NoSQL, the authors discuss how Bigtable systems store data using row and column keys and how they are used in several business applications.
