1. Spring and Java
>> Just-In-Time Compilation for Java Performance: Recent and Ongoing Improvements [inside.java]
The JVM’s JIT compilers keep adapting – a quick survey of recent performance improvements and the work underway around Valhalla, Leyden, and Panama.
A very useful look at where Java’s runtime speed comes from and where its compilers are headed.
>> Spring AI and TypeSafe Jev: Fast, Cheap, Structured Decisions [spring.io]
Sometimes an AI application needs a decision, not more text. Jev is for that 🙂 (when it opens up agian).

2. Technical & Musings
>> Diagrams as Code: Mermaid Support on the new Foojay [foojay.io]
Foojay now renders Mermaid diagrams directly from fenced code blocks. Frank Delporte walks through sequence, class, state, ER, and Gantt examples, then covers theme-aware rendering, syntax checks, and accessibility. A practical way to keep diagrams for Java APIs and workflows in the same reviewable source as the article.
