Back in 2005, when I was writing Java software for an embedded home automation controller, we ran into a little unforeseen problem. The embedded virtual machine we were using implemented only the Java 1.3 API, and so did not offer any logging facilities (which only Java 1.4 started having). We ended up using the logging […]
In my professional development, I felt that I had always neglected the field of web aplication development. To correct this I’ve started a little side project with Spring MVC, a web application to help a Toastmasters club’s Vice-President Education with their duties. Between the official documentation and the Spring in Action book, I found the […]
Today I searched for a Maven plugin that would filter some of my source files before compiling them. An equivalent to the resources plugin with filtering turned on, but for Java sources, that would replace occurences of, say, ${token.name} with somevalue wherever that string occurs in the source files. I could not find such a […]
Spring is a great framework for externalizing the object graph of your application. Typically you write an XML config file that defines a number of Java objects (or “beans“) and how they are supposed to relate to each others. For example, suppose you have a class ThermalNode whose instances need to hold a reference to, […]
I am now convinced that even the most trivial pieces of code must be unit-tested. Recently I’ve been working on a Java implementation of a building thermal model. A textbook model with thermal nodes and thermal capacities and conductances between them. This is supposed to eventually become part of a generic testing harness for home […]
