Reading List ::: from JavaSpecialists
Issue 317 - Explicit vs Diagnostic GC
How many times have we seen programmers call System.gc() to "help the garbage collector"? Unfortunately far too often, with potentially terrible performance implications. In this newsletter we explore the explicit and the diagnostic GC and how we can force a GC, even if explicit GCs are disabled.Issue 316 - Code Before super() - JEP 447
Java 22 preview allows us to write code before the call to super(). There are restrictions. We are not allowed to refer to "this" in any way. We thus cannot set fields before calling the superclass constructor. But what if the superclass constructor calls our methods? In this newsletter we explore a workaround using ThreadLocals.Issue 315 - Random Newsletter
Classes java.util.Random and java.util.SplittableRandom didn't used to have a common ancestor, making it difficult to write methods that take either. This was finally fixed in Java 17. Let's have a look at some random Java topics together.Issue 314 - Harnessing the Power of ChatGPT 4.0 From Java
A few years ago, the second oldest man in our village Chorafakia wrote a book about the history of our area. Only catch - it was in Cretan Greek. I tried to read it, but couldn't. Google Translate shrugged at the strange Cretan dialect. Then ChatGPT 4.0 came along, and we can interact with it directly from within Java. In this newsletter we have a look at how I was able to translate this masterpiece into four languages: English, German, Dutch and Slovak.Issue 313 - Selling Our Java Skills
What causes opportunities to disappear? Is it #1 the market has lost interest in what we are selling (Java is dead). Or is it #2 we have personally become irrelevant (AI writes better code)? Or could it be something else? Join me as we read about my recent dumb mistakes :-)Comment Wall

Maciej Pocwierz, a Senior Software Engineer, recently revealed a significant issue—an empty S3 bucket can unexpectedly result in a substantial AWS bill. In his case, nearly 100,000,000 S3 PUT requests were executed within a single day, leading to a bill that was far from negligible.

During her presentation at QCon London, Ines Montani, co-founder and CEO of explosion.ai (the maker of spaCy), stated that economies of scale are not enough to create monopolies in the AI space and that open-source techniques and models will allow everybody to keep up with the “Gen AI revolution”.
By Olimpiu PopJEP 474: Generational Mode Now Standard for ZGC in Java
JEP 474, ZGC: Generational Mode by Default, has also been targeted for JDK 23. This JEP proposes to use the Z Garbage Collector (ZGC) from non-generational to generational mode by default. The non-generational mode will be deprecated and removed in a future JDK release. This will reduce the cost of maintaining the two modes, so future development can primarily focus on Generational ZGC.
