An interesting set of slides by Simon Brown from a talk he gave about the role of the architect. A PDF is attached to the linked post or you can view the slides online. Wish I had heard the talk (see below). The Frustrated Architect: Software architecture plays a pivotal role in the delivery of [...]

You know, just because Java is going to gain a switch statement that works on java.util.String still doesn’t make it right. It’s still a code smell for an OO design fail. Although the diamond syntax and lambdas are way overdue (see article). Java is not the new COBOL | Craig Tataryn’s .plan: A switch statement [...]
world– by Robert Merkel at Larvatus Prodeo. Published October 14, 2011 at 09:02AM The technology world has just lost another giant, though one without the towering public persona of Steve Jobs. If you’re not actually a programmer, you’ve probably never heard of Dennis Ritchie. But the vast majority of software you use was built using [...]
“Jobs’ genius is that he builds these products that people really like to use because he has taste and can build things that people really find compelling. Ritchie built things that technologists were able to use to build core infrastructure that people don’t necessarily see much anymore, but they use everyday.” via Dennis Ritchie: The [...]

Recently been deeply stuck in building software (apart from starting my PhD part-time). A long time ago I wrote about dynamically loading Spring contexts and component discovery – this system I’ve been building is an evolution of that one. We decided to adopt an most REST-based style to integrate between our components. Now, “run-time” discovery [...]
I found a massive bug in Eclipse – it has a copy and paste function. In Eclipse’s defence, Intellij IDEA and Netbeans also exhibit identical broken functionality.

I’ve just spent the past two days trying to make Spring transaction management work with JPA-annotated Hibernate-backed persistence classes that need to have multiple persistence units with transaction propagation REQUIRES_NEW between the two. For a start, the documentation is merely a series of outlines of brief hints. One measly section.The laughably short Spring 3 doco [...]
Most developers familiar with agile methods are familiar with the idea of the spike. A spike is a time-boxed task that concentrates on clarifying the unknowns in your project. Usually these are technological (“can this be done with this technology?”) but they are also sometimes in the area of the business domain (“is this a [...]

Using these three Spring features will enable us to be able to place a JAR file containing an interface implementation, and a Spring context XML file matching a particular pattern, into the classpath of our WAR, and on restart, we can dynamically pick up the newly inserted features into our application installation.
