From Spec-Driven Development to Living Specifications in Java Projects

Coding agents have changed the speed at which we can produce software. But producing code faster does not automatically mean producing better software.

As I started using agents more frequently in real-world software development, one question became increasingly important: how do we give an agent enough freedom to be useful without losing engineering intent?

Trying to control every line of code generated by an agent removes much of the value it can provide. At that point, it might simply be faster to write the code ourselves.

Foojay Podcast #66: Let's Talk About Java Code!

In this Foojay podcast, we dive into a few articles that were published recently and focus on code.

Igor Kulakov of JetBrains gives us his insights into the tool he created to find duplicate content in documentation.

Rijo Sam explains how you can generate real random values and how he created a train departure display.

Maxillian Arruda explains in a very detailed post the different ways to construct a complex Java object.

And we start with Wim De Troye about the code changes he had to do in a project that got upgraded from Spring Boot 2 to 3.

Make the life of your developer client's easier with smart builders

We often hear the phrase: “Make the life of your client easier”. But, what about the developers? They are the ones who will be working with the code you write. It is important to make their lives easier too.

Despite the target customer of your solution, you’ll be creating code that will be maintained by other developers and, sometimes, it may include you as well. Choosing good approaches and techniques will make their life, or your life, easier probably.
