Spicing up your app’s performance - a simple recipe for GC tuning
The garbage collector is a complex piece of machinery that can be difficult to tune. Not surprisingly, many developers dread touching the GC. If you don’t give the GC just a little bit of care, your whole application might be running suboptimal. This blog post shows how we got two production applications to perform better by following simple tuning steps.
Coroutine Gotchas - Bridging the Gap between Coroutine and Non-Coroutine Worlds
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?
If 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
How to prevent common performance defects with the jPinpoint PMD rules
Prevention 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.
The hyped, happening and happened application frameworks and Java runtime @ bol.com (Part 5)
We asked 25 developers, five tech leads and someone “who does unspeakable things with technology” - more commonly known as our principle tech lead which technologies (tools, libraries, language or frameworks) they believe are hyped, happening or happened:

Know what you deploy - a script using git log for listing all features that go live
Introduction
For me, even after having pushed the deploy button many times, deploying to production keeps being dreadful. Accidentally pushing an unwanted feature that sneaked in somehow is one of the many things I am afraid of. In this...
