What Is A Class (and why to avoid static methods)

There are many debates in software development, from how to test, to languages, to frameworks, and everything under the sun. Despite my oblivion to the technical details of many of these debates, what I’ve seen is that many of them hover around the lofty heights of roof trusses without understanding the subterranean foundations that build the houses they are comparing (wow, that was poetic: +1500 hipster points). In my short software development career thus far, I have been introduced to 2 paradigms of software development: procedural and object-oriented. And…

Why Are We Mocking Like This?

People like labels that they can classify themselves under. It’s a nice way to have a club you can belong to, and an opposing club you can speak against. In political rhetoric here in South Africa, one group of people will feel complemented when calling them ‘capitalist’, whereas another will feel completely insulted. It’s the same with the term ‘socialist’. This phenomenon seems to also exist in the software development sub-genre of reality. Of late, I’ve been reading and discussing the tensions between the unit-testing practices of…

Broken Windows and Broken Code

This week, I have been reading Tipping Point by Malcolm Gladwell. It talks about how large social movements happen, breaking it down into three things: the people involved, the stickiness of the message, and the context. In discussing the context, he introduces the Broken Window Theory by James Q. Wilson and George L. Kelling, which explains how environment plays a big role in bringing about bad behaviour in individuals. This is my simple understanding of it. In New York, in {{ somedaterangebefore1990 }}, there was a high crime rate. There was a…

Spock: Making Java Testing Groovy

In my previous post, I alluded to how I was introduced to the Ruby cult some time ago. I decided to try out the language for myself. Now, being used to statically typed languages, I’m not really a fan of type enforcing only happening at run-time for languages such as Ruby, JavaScript and Python. But one I really like about Ruby, similar to what I found about Python some time ago, is how human-readable it is, making understanding what the code does a lot easier. Groovy, a language that…

Spring Field vs Setter vs Constructor Injection

Lately, I have been immersed in the world of Java and its various frameworks, tools and language features. I’ve also recently discovered that Java is not cool. I found myself at a gathering of developers some time ago, where they attempted to proselytise me into the ruby cult family. Unfortunately, since puberty, I have had trouble growing enough facial hair to be seen as ‘one of them’. In this Java world, it seems that the Spring framework is king for large applications. And their IoC container is very useful…

Simple Applications Change The World

When someone dreams of being a ‘software developer’ or ‘programmer’ (or whatever the other ill-defined terms are for someone who creates software), they imagine someone highly intelligent someone solving complex algorithms that will solve the {{ world.generateRandomProblem() }} crisis for humanity and make this world a better place. At least that’s what I thought. Not everyone is a ‘change-the-world’ kinda guy, but I’ve found myself to be one. Whether I found myself walking the busy corporate streets of Johannesburg, visiting family in Uganda or being transported into a place…
