Writing code gets cheaper with #AI. Understanding architecture does not. That’s why teams drown in systems nobody fully understands. Sven Reinck shows how dependency visualization can make large codebases navigable again: javapro.io/2026/06/10/beyond…

#Java developers spent years tuning pools, GC & startup behavior manually. With #Java26, the #JVM increasingly handles concurrency, warm-up and optimization itself.

REST-Security in #Vaadin endet nicht beim Login. REST-Adapter, Bearer Tokens & Client-Anbindung müssen sauber zusammenspielen. @SvenRuppert zeigt das in seiner dreiteiligen Serie:

Why are so many #AI backends harder to debug than to build? Reactive pipelines solved scalability — but often created systems nobody enjoys maintaining. Damiana Nascimento shows where #VirtualThreads simplify #RAG & #LLM services.
