Here’s my quick summary of the key sessions I followed today 👇
🤖 A chatbot demo evolving from a basic prompt into an advisor-powered assistant (search, translation, retrieval), then full tool/agent routing.
🧠 Java memory deep dive: JVM memory areas, what changed across releases, how to spot memory issues, and how GC choices impact performance.
⚡ Project Leyden explained: optimizing Java peak performance, with response-time comparisons versus AOT approaches.
🔐 MCP in practice: how it works, how to secure it properly, and a live MCP server demo.
📦 Buildpacks vs containers: two ways to ship apps to production, with major differences in DX, security, and CI/CD flow.
🛡️ Post-quantum crypto in Java: generating quantum-resistant shared secrets with Java 24+ KEM (keygen + encapsulate + decapsulate).
🧩 Pattern matching since Java 14: evolving syntax, future enhancements, corner cases in switch, and rules on when it’s actually worth it.
Day 1 delivered a solid mix of Java fundamentals + future-forward tooling 🔥
