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.

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 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...

I am back with more stories about our adventures in the world of Java.
From the distant past to recent events. I hope to entertain, enlighten, and encourage.
So hold on to your hats.
For software developers in IT, there are times when you find yourself present at the birth of a major application.
Normally these are dream assignments. But consider the following additional factors.

We thought we'd get to know a little more about the author!
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...

Today, we are being inundated with data. So much so, that IBM estimates that in 2012, 2.5 quintillion bytes of information are generated every day. That's a million trillion bytes of data, more data than we can fathom and considerably more than we can easily process. Online, every web-page we visit, every link we click, every...

The simple build tool (SBT) is a tool for building Java and Scala projects. SBT aims to build well and allow users to customize endlessly, but above all, SBT strives to provide consistency of basic concepts so that, once learned, you don’t have to unlearn them as you dive deeper into the build...

Have you wanted to do something with asynchronous I/O? I did. After doing some work with Node.js, I wanted to find a way to get some of the goodness of its programming model for Java.
The Acteur project is the result - a framework for building scalable, asynchronous web applications using Netty + Guice - was the result. The programming model is a little unusual - you treat constructors as...
