When I speak to people about how it is possible to continuously deliver customer value with near zero issues, I usually get laughed at. After I tell them that there is nothing to laugh at, people start challenging me on how I integrate with other systems, how I manage defects, how I deal with changing requirements, how I manage regression issues, ...

The 4 Levels of Freedom For Software Developers

software-development-2-logo

For quite some time now I’ve been putting together, in my mind, what I think are the four distinct levels that software developers can go through in trying to gain their “freedom.” For most of my software development career, when I worked for a company, as an employee, I had the dream of someday being free.

Through The Looking Glass Architecture Antipattern

software-development-2-logo

An anti-pattern is a commonly recurring software design pattern that is ineffective or counterproductive. One architectural anti-pattern I’ve seen a number of times is something I’ll call the “Through the Looking Glass” pattern. It’s named so because APIs and internal representations are often reflected and defined by their consumers. The core of this pattern is that the software components are ...

Java’s Volatile Modifier

A while ago I wrote a Java servlet Filter that loads configuration in its init function (based on a parameter from web.xml). The filter’s configuration is cached in a private field. I set the volatile modifier on the field. When I later checked the company Sonar to see if it found any warnings or issues in the code I was a bit ...
