What should be in a source control commit message for a single file add?
Reason: The reason for the file should be in a comment in a file so it would be a duplicate to also include in the commit message.
File add: Already part of the commit

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.

How to use JDK 7's AutoCloseable for more than just I/O - it's actually quite useful in your own APIs. See the real full blog over on timboudreau.com.

One of my favorite sessions at Jfokus 2013 was presented by Typesafe co-founder and Java Champion Jonas Bonér. I always enjoy discussions about how technology evolves over the decades, how we break away from concepts, then sometimes weave our way back via the latest and greatest thing, which can sometimes appear strikingly similar to something that was very much in vogue a decade or so earlier....

Building a Java Web Application with Gradle
by Benjamin Muschko, author of Gradle in Action
Gradle provides a build-by-convention approach for certain problem domains like Java projects by introducing pre-defined project layouts with sensible defaults. In this article, based on chapter 3 of Gradle in Action, author Benjamin Muschko explains how to apply the Java, War and Jetty plugins to build...

Multimethods in Clojure
by Amit Rathore, author of Clojure in Action, Second Edition
Clojure multimethods support not only multiple dispatch but much more. Indeed, once you look past multiple dispatch, a commonly asked question is whether a language can dispatch on things other than the types of values. With Clojure’s multimethods, methods can be made to dispatch based on any arbitrary rule....

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...

Node in a Nutshell
by Alex Young and Marc Harter, authors of Node.js in Practice
We live in a world of highly connected multicore servers, where web applications are expected to scale from dozens of users to millions. New demands are being placed on developers by the real-time nature of the modern web. Developers are looking for fresh solutions to solve scalability issues—whether it’s to take...

Sometimes, life drops a house on your code. Sometimes, it's flying monkeys. Most of the time though, the damn stuff just stops working and it's nothing so obvious as being crushed by a Kansas farmhouse or being carried away by winged primates.
For this last common case, there are a good number of great tools to help you out. JMeter may help you to reproduce the conditions under load, while...

by Chris Buckett, author of Dart in Action
Overloading happens when you provide a new implementation customized to your particular class, which allows you to overload the common operators such as > (greater than) and < (less than). In this article, based on chapter 8 of Dart in Action, author Chris Buckett explains how this function helps you create truly self-...

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...

Our team of Java developers consists of people with various backgrounds and skill levels.
Everyone has a role and is assigned tasks based on that role.
Team members are expected to know basic programming concepts, core Java and core J2EE.
In addition; database access, web-browser, client/server concepts are required as well.
It didn't take long for our team to realize there was a lot more to know...
