Tim's Topic: Open Rewrite: A la carte
OpenRewrite allows you to automate the maintenance on your code. A large collection of existing recipes allows you to upgrade, improve and secure your applications. But what if you want something beyond what’s already available out of the box?

In this live demo we’ll explore writing custom OpenRewrite recipes. That might be small additions to existing migration recipes, or larger efforts to adopt breaking changes. Walk away knowing exactly how to upgrade that internal library or framework, or how to contribute recipes that everyone can then use.

Stijn's Topic: (self-)Documenting Code: low friction doc creation & maintenance
The goal of software documentation is to be useful: providing clarity and support to developers maintaining and expanding the codebase.
Yet, the time spent on external tools to write and update documentation often feels like a distraction from actual coding.
In this lightning talk, we’ll explore a more streamlined approach: using tools and techniques that allow developers to stay in the codebase while generating useful documentation artifacts.

From naming conventions, comments, and tests to diagrams-as-code and static site generators, we’ll dive into practical strategies to reduce friction and make documentation as low-effort as possible. The aim isn’t to eliminate documentation tasks, but to integrate them smoothly into the development workflow. Providing actionable tips, this session is aimed at developers looking to maintain useful documentation without breaking their
flow.
