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.
