Today, May 22, my book about ZGC is finally ready and available to order! I can recommend reading it if you want to learn more about the magic nature of ZGC. You can order it here (among many places): www.routledge.com/The-Z-Garbag...
This book explains how the Z Garbage Collector was designed, why it was designed this way, the common pitfalls to avoid when using ZGC in JDK 25 and how to get useful information from the garbage coll...

Lazy init, self modifying code. Memory ordering, volatile, fences, Icache. Dynamic linking, LLVM limitations. Simple: .o, linking, relocating, exports, internal patching, more codegen. Simple phases.
Switching to Sea of Nodes(SoN), why or why not?

After a year of daily AI-assisted coding, I wrote down what actually works — spec-driven dev, skills as guardrails, incremental verification, and the 4 gaps.

AI is an amplifier. It magnifies discipline and chaos with equal enthusiasm.

AI can be used as a trial developer of your software. If an AI can write effective code, test, and tune it, that a great start.
In this exercise, I get an AI to write a low latency benchmark in Java for Chronicle FIX (closed source so not indexed)
