Actually, it’s even more frustrating when the code is mine. The “deep thinking,” as they call it, which is always required before even a small issue can be ...

For instance, I think we agreed here and here that model objects are mere syntax sugar and we might as well not have them at all, they are useless abstractions that do not offer any functionality. Nevertheless, let’s try one more time, this time through ...

Parallel code, which is code that runs on more than one thread, was once the nightmare of many an experienced developer, but Java 8 brought a lot of changes that should make this performance-boosting trick a lot more manageable. Parallel Streams Before Java 8 there was a big difference between parallel (or concurrent) code and sequential code. It was also ...
