Acteur is a pattern for pipelining work - a little DI functional goodness for Java. I might have been speaking Swahili when I wrote about Acteur last month. So here's a simple explanation of the design pattern behind it, with a simple sample project.

Defining Functional Data Structures by Paul Chiusano and Rúnar Bjarnason, authors of Functional Programming in Scala Functional programs do not update variables or modify data structures. This raises pressing questions—what sort of data structures we use in functional programming, how do we define them can in Scala, and how do we operate over these data structures? This article,...

So I haven't posted a blog here since 2009 - and haven't work for Sun or Oracle since early 2010. It's been a wild few years working on a number of things as diverse as giant clouds to control software for cameras which go down oil wells. And I have a new blog at timboudreau.com, naturally using a blog engine I wrote myself (I gave myself a project to learn node.js). Currently I'm architecting...

Natural User Interaction with Drag-and-Drop by Rob Crowther, author of Hello! HTML5 and CSS3 The HTML5 spec is ground-breaking in many ways, but one of the key ways is that it specifies both the syntax of the HTML markup and the APIs you should use to manipulate the document with JavaScript. In this article from Hello! HTML5 & CSS3, author Rob Crowther discusses simulating desktop-like...

More than a few days ago a friend pinged me complaining that recent Eclipse release was quite sluggish. Since she had taken my performance tuning seminar she knew exactly how to get and read a GC log but as we all do, she was looking for a second opinion. After looking at the log for a minute it because quite apparent that the default configuration left the IDE starved for memory. After a bit...

Java Web Services and XML

In this blog entry I outline the steps necessary to deploy JAX-RS (JSR 311) RESTful web services to the Oracle Cloud. We'll be using Jersey, which is the reference implementation for JAX-RS, and JDeveloper, which is my primary Java IDE. Step 1. Create a Jersey Library in JDeveloper Download the latest version of jersey-bundle.jar, which at the time of this writing is version 1.17.1. Start...

Java Tools

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...

Atlassian has made some seriously great products, for example the project tracker JIRA. We recently upgraded our rather archaic version of JIRA at Magnolia to the latest and greatest offering. Everyone in the team found something in this upgrade. Some of us were desperate to use GreenHopper, others were looking forward to a better LDAP integration, and my personal favourite was the new REST API...

I was pleased at JavaOne 2012 to have an opportunity to converse with JFrog founder Yoav Landman (@yoavlandman). JFrog, in case you're unfamiliar with the company name, is the inventor of Artifactory, the Java repository management solution that won a 2011 Duke's Choice Award. They also regularly produce cool swag tshirts (see below). Yoav was very busy at JavaOne 2012, but with advance...

Java User Groups

Bugs are inevitable. Even after you thought you have finished coding your work, another bug creeps in, making you want to wish the bugs were real tangible objects that you could squish with your bare hands. Being a developer, you should be armed with the right weapons to battle bugs for they come almost all the time. In fact, they are building yet another Death Star. If you don't get vigilant,...

Acceptance Test Driven Development (ATDD) is a method wherein business stakeholders, analysts, testers and developers collectively specify and agree on what needs to be completed in the project. Requirement specifications are set and verified even before actual development starts. This ensures that only those value-adding features are delivered to the business. Instead of validating after the...

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. Functional Programming puts the spotlight on what we want to get out of our codes rather than how we are going to execute them. With this in mind, codes are relatively easier to understand and are less error prone, due to the fact...
