In my previous post, I mentioned writing performance tests anytime you need to do optimization to slow areas of code. Writing effective performance tests can be tedious in Java. Every test you want to run in Java needs to have the same timing logic before and after the tests. Groovy‘s Closures make separating timing code [...]

The Maritime Dev Con was a huge success. About 95 people total attended the event making it a huge success for developers in the Maritimes. I had a great time at the event and met a bunch of really cool people. The presentations I gave went well with a number of attendees. I’m putting up [...]
There is going to be a maritime developers conference coming up on June 18th in Moncton. It is going to be a great opportunity to have developers from Moncton and other areas of the maritimes get together and learn a bit about other languages and technologies they might not have been exposed to. All of [...]
Last night I gave a talk at the Maritimes Java User Group in Moncton. The presentation was an introduction to Groovy for Java Developers. I had initially done a 3h internal course for iWave Software to bring them up to speed on what Groovy is and why we should use it. I took this course [...]
Problem. Bugs happen. The common solution to this problem is to fix the bug and release a patch. Version 1.0 has bugs, version 1.0.1 fixes those bugs. Inevitably at some point in time you will need to put together a list of all of the changes in a release. For me, this needs to go [...]
A lot of the work I do deals with integration with a third party system. Each of these systems typically has their own API and mechanisms for handling errors. Often times writing some code to ‘wrap’ the API is required to make it easier to use from an application. Many times this ends up being [...]
I had the privilege of attending the SpringOne2gx conference this year in New Orleans. This is the first tech conference I have attended. Where I live, in Moncton, is a bit off the beaten path and is a bit far to travel to these types of conferences regularly. Past employers of mine have not always [...]
One of the projects I am working on uses Apache Maven for doing builds. Usually, I let the Maven Release plugin take care of all of the version numbering. When I instruct maven to generate a release version or do a branch, it will ask for the new version for each of the artifacts in [...]
I have written about the Groovy language a few times. It is a wonderful language and integrates seamlessly with Java. Recently, I have found that it can be very useful for templates and filters. Using Groovy for Filtering Consider an application where there are many events that fire on certain conditions. The Observer pattern is [...]
I’ve decided to use Apache Maven for building the code for my new project. So far I have had a love-hate relationship with Maven. If you don’t know what maven is, the folks over at Apache say Maven is … “… a software project management and comprehension tool. Based on the concept of a project [...]
