Coroutines are a wonderful way of writing asynchronous, non-blocking code in Kotlin. Think of them as lightweight threads, because that’s exactly what they are. Lightweight threads aim to reduce context switching, a relatively expensive operation. Moreover, you can easily suspend and cancel them anytime. Sounds great, right?
Coroutine Gotchas - Bridging the Gap between Coroutine and Non-Coroutine WorldsIf you’re performing web requests with Spring Boot’s WebClient you perhaps, just like us, read that defining the URL of your request should be done using a URI builder
Avoiding memory leaks with Spring Boot WebClientPrevention is better than cure - a fundamental principle of health care that also applies to modern software development. The later a bug surfaces, the more effort it takes to repair. From our own experience we know that this especially applies to performance bugs.
How to prevent common performance defects with the jPinpoint PMD rulesIntroduction MapStruct is a framework that alleviates us, programmers, from the unexciting task of writing code to copy one object model to another, field by field. This blog elaborates on how to write MapStruct mappers for object hierarchies. If,...
How to write MapStruct mappers for object hierarchiesIntroduction I was once told that a good programmer is a lazy programmer. A good programmer avoids typing tedious code, where the code could basically write itself. Self-writing code – wouldn’t that be great? Unfortunately, we’re not quite there yet.
Mapping object models with MapStruct - a case studyWhen it comes to developing software we use the adagio: You built it, You run it, You love it. Same should hold for all the -ilities or non-functional requirements. So, one should love their logging.
Love your loggingWe take a sneak peek into the Utrecht JAVA User Group (JUG) Meetup next week, February 24th. Topics will be: are End-to-End test architectures a Dead End road? And there will be some live hacking: Breaking into your Java web app. This will really give a feel for the importance of security.
