>> Tool Calling in Spring AI 2.0: A Composable, Agentic Architecture [spring.io]
Spring AI 2.0 is out this week (see below) and turns tool calling into a first-class element, making agent loops easier to observe, compose, and extend. A strong read for anyone building agentic systems on Spring who needs more than a black-box function call.

2. Pick of the Week
Paul Graham’s short essay is a crisp reminder that the most valuable ideas are often both broadly useful and genuinely surprising. It is a useful lens for technical work too: even a small amount of novelty can matter when it attaches to a big enough idea.
