Indonesia has released the domain .id to public with Indonesia ID, and more more website using this domain, the domain is costly around $50/year.
in Another world, with this domain, we can make the domain become an identity portal.
And yes we are the one that using it (http://www.merv.id), and we also release the OAuth Server, take a look https://github.com/meruvian/yama, a 2-in-1 project that...

The Java is a platform which grown up quickly, for many rations such it can write once time and run anywhere, it runs languages on JVM. There is a myth that Java cannot compile its sources on run time, but it's truth?
Have a dynamic language is important to make some projects, for example, calculate taxes to different cities, so the source should be on the database and each city it puts the...

Recently, I was asked to participate in creating another Java application at my company.
It was to be our team's third major Java application since 2002.
We felt we had plenty of wisdom from our previous two Java applications to apply to our third one.
One of our first steps was to form an application architecture sub-team.
This sub-team's purpose was to provide the development team with a solid...

My company uses a large number of software applications to support all aspects of its business.
These software applications are either "bought" or "built".
The portions of the company that cannot be supported by purchased software are
supported by custom developed, in-house, applications.
A variety of technologies are used to create and build these custom applications.
The Java framework has been...

A while ago, I was asked to evaluate another Java application that was being used at my company.
It was a point-of-sale app, developed entirely "in-house" by one of our overseas affiliates.
I wondered what their MVC model would look like.
How different would their Java app be from the ones I have worked on?
I started my evaluation by learning all I could about the architecture and design of this...

Very soon, it will be time for the annual Java One conference in San Francisco, California.
Thousands of Java-fanatics will make the journey to my favorite city "by the bay" (and my home town).
Thousands more Java-fanatics will not attend (including me) and wish they could.
I hope all attendees will have a great and productive time at Java One 2013.
My general advice to attendees is, "Make the...

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.

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,...

Tuning Java code presents many challenges and addresses several goals.
One of these goals is to make the application "run faster".
Recently, our end-users were getting multiple-second response times from our web application's home page.
This was unacceptable.
We were asked to see what we can do to make the web application "run faster".
We began by looking at the usual suspects... database access...

One of the first things we did as we began to learn about Java was to create our own library of Java books.
Every member of the development team was given the chance (and funding) to build their own collection of books.
In time, these book collections became a sort of "comfort blanket" for the developers.
In addition to being a valuable source of reference material,
these collections act as a...

One of the biggest challenges facing us during the creation of our first Java application
was learning to develop with the Java programming language.
We were concerned about how well our team of developers would learn and adapt to Java.
Since Java was an object-oriented programming language, we had object-oriented concepts to learn as well.
Our first Java training class was titled, "Developing...

It’s been a while since I’ve featured a more technically focused post on this blog, so I’ll try to remedy this today. One of the things that became obvious fairly quickly when we released Magnolia 5 in summer 2013 was that most users, when creating custom apps, create so called Content Apps. In other words, and not so surprisingly, people still use Magnolia as a content management system. This...

Just recently I was engaged to assist with an application that wasn’t behaving. The application, running in a 1.7.0_45 JVM, relied heavily on a 3rd party SAAS framework. That vendor provided my client with a list of 26 different JVM flags that should be set. When faced with this long list of flags I couldn’t resist asking why all the flags and why these flags. After all there are more than 700...

This post introduces a new Java actor based open source sub-project of the project "Learning Actors in Java". This work will develop a premises guardian system. A premises guardian system is a distributed application whose purpose is to support the physical protection of premises such as office buildings, campuses, apartment complexes, shopping malls, etc. Protecting information...

Remote systems cannot be ignored. They are the heart of actor programming. The ability of an actor application to smoothly scale out geographically is a tremendous advantage in meeting the challenges of growth. Today we will learn the basics of setting up for remote interaction between actors. If you wish to set up to try coding a set of remote actor systems and do not as yet have a...

Configuration of an actor system affects the way in which the Akka actor libraries and microkernel interact with actors. The visibility of a configuration is limited to the specific actor system with which the configuration has been associated. The effective configuration for any given actor system is a merger of three sources. In Fig. 1 below the precedence of...

This week I am presenting a coding of a simple two actor application designed to show actor creation, message passing, and actor termination. This application is called the "Fortune Cookie Application". It is the next state of the art beyond the HelloWorld program. Despite its simplicity this application shows the elements that every actor application uses.
What We Will Be...

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...
