I Finally Understand What MCP Is For
If you’re a developer, you’ve probably heard about MCP — the Model Context Protocol. It’s the hottest thing in AI, and posts and videos about it are appearing everywhere. Maybe you’ve even looked at the documentation, nodded along with the technical explanations (“it’s a protocol for connecting AI models to tools”), and thought, “But why…

A Really Easy Way to Add AI to Java
My latest video is about accessing the Claude AI API in a Spring Boot application: The title is a little click-baity for my taste, especially because the LangChain4J project is even easier.

Spring provides all the necessary infrastructure to make AOP doable. You can define aspects using annotations, and Spring will auto-generate the necessary proxies to implement them. As an example, the…

I wound up too busy to maintain my daily reports, but here are a couple of items I want to highlight as important take-aways from SpringOne 2GX. Rather than just recap sessions or dole out marketing-type praise, I’m going to focus on some things I learned that I didn’t necessarily expect. A lot of people…

SpringOne 2GX Day 1
… or day 2, by the official count. Today was the first full day of sessions, though, so I’m counting from 1. From now on, I can only comment on the sessions I attended. There were many parallel sessions I wish I could have gone to, but until I get one of those cool Time…
