19:20: Adding Built-in AI API support to Mastodon
Speaker: Thomas Steiner, Developer Advocate @ Google

Mastodon is a free and open-source software platform for decentralized social networking. The server software itself is powered by Ruby on Rails and Node.js, with its web client being written in React.js and Redux. In this talk, I will show how I added support for two built-in AI APIs that are currently in origin trial in Chrome, and show how you, too, can use these APIs for fun and profit.

20:00: Accessibility 101: Quick accessibility wins that are easy to implement
Speaker: Claudio Orlandi, Senior Software Engineer @ MVST.

The ‘Accessibility 101’ talk introduces practical, easy-to-adopt techniques to improve web accessibility, aligned with the European Accessibility Act (EAA). Learn how small changes—like proper heading structures, keyboard navigation, and ARIA labels—can create a more inclusive experience. I’ll demonstrate testing with tools like Axe Core, Lighthouse, and Pa11y, and show how to integrate these checks into your workflow. Whether you’re new to accessibility or need a compliance refresher, this session provides actionable steps to make your site more accessible—no overhauls required.

20:30: Drinks and networking!
