Imagine the following scenario: a Java service that ran flawlessly yesterday suddenly starts consuming 90% CPU, barely responding to user requests. Users encounter timeouts, and the operations team is under immediate pressure to triage the incident. In these situations — whether the…
Beyond UML: Clean Software Architecture in the Age of AI‑Generated Code
Abstract Today we write more code in less time than ever before. AI systems act like permanently available junior programmers: They produce thousands of lines of code in minutes – but who takes responsibility for the software architecture? The real problem is therefore…
Structured Concurrency in Java 26 (JEP 525 Deep Dive)
The Java 26 Evolution of Safer, Predictable Multi-threading Java has long provided powerful concurrency primitives. Threads, executors, futures, and more recently virtual threads allow applications to scale across cores and I/O boundaries. Yet many production failures are not caused by…
Comparing transitive dependency version resolution in Rust and Java
