Joy at QCon New York

Joy isn't the typical emotion that comes to mind when one pictures enterprise software and enterprise software developers, but technical culture is changing rapidly and more people are recognizing the business value of joy. It's an exciting time to be a software developer.

Multiplayer tic-tac-toe in Java using the WebSocket API, Netty (NIO), and jQuery

It was big news in 2010 when Twitter migrated their search from Ruby on Rails to Java-based Netty. Not only was it big in the news department, but it was also big in the results department: Twitter reported their search performance increased by 3x. In this post we'll explore Netty by using it to build a game of multiplayer tic-tac-toe.

Fixing Fancybox with AJAX (and Wicket)

A page I'm working on accepts multiple image uploads. Once the images are successfully processed asynchronously on the server, an image panel on the same page is automatically refreshed. The AJAX callback works fine and updates the panel view with the newly uploaded photos, but the net result is that Fancybox stops working completely.

Connection pooling with Hibernate 3.3.x and C3P0

Hibernate uses it’s own built-in connection pool out of the box. There are some pretty heavy duty sites running with the default connection pool enabled in production despite the obvious warning against doing this.

Beyond Java

We explore a Forrester report which asserts that Java is a dead end for enterprises and business software should be built with a 4GL such as webMethods. Let's explore why Java won't disappear from the enterprise any time soon.

The future of Java in the enterprise

Java is a utilitarian, status-quo ecosystem for getting things done, albeit not very quickly. This is a good thing. Instead of worrying about sharp edges, developers get to work with a very stable, very slow moving target. What's the future hold for enterprise Java developers?

Desire paths

A desire path represents the evolutionary nature of how people interact with their environment. An engineer designs a concrete path, but people find it more convenient to create their own. Software isn't any different. Users bump up against the limitation of an application but find their own workaround through sheer necessity.

Integrating Uploadify with Java using Apache Wicket

One of the most requested features on any site that accepts file submissions is the ability to handle multiple uploads elegantly. The current HTML standard only permits one file upload at a time, which makes transferring a large number of files quite tedious. This tutorial will show how to painlessly integrate Uploadify and Java using Apache Wicket.

Be a Revolutionary

Good developers always try to deliver amazing software in spite of obstacles. The perfect methodology for our team may not integrate well with the rest of the organization. The perfect programming language may be unknown to most developers on the team. The perfect architecture may require three months to develop but the deadline is three weeks away. Good developers embrace a harmonious balance between pragmatism and idealism.

Is SOA doomed?

The spirit of SOA is fantastic; adaptable, flexible, maintainable, loosely-coupled applications supported by open governance, strong relationships between business and technology folks, and co-operation across all silos and levels of an organization. What's not to love? We'll explore the pitfalls of SOA and explore the future of SOA in the enterprise.

Reactive Systems: Easy To Program, Now Easier To Manage

On top of user expectations being significantly higher today than a decade ago, the pressures facing enterprise operations teams to manage resilient, responsive systems is brutal; most existing technologies available today are not designed to deploy and manage reactive systems running on clusters.

Actor-based Concurrency for Reactive Systems

According to reactive manifesto, reactive applications are built on four guiding principles: responsiveness, resiliency, scalability, and message-driven architecture. In Kevin’s view, those four guiding principles are closely related in that both resiliency and scalability are necessary qualities to ensure that a system remains responsive, i.e., “quick to react to users,” under varying working conditions and loads.
