This **coworking and networking** meetup is for neurodivergent people to get our tasks/projects/work done and to connect with other neurodivergent, whether for focus work or just finding someone who understands what you’re working on. **PLEASE READ THE EVENT DESCRIPTION BELOW:** So we can be self-accountable for our own comfort. **Location:** Werkräume inside Humboldt Forum https://maps.app.goo.gl/Jw5totHbQadfsJsE8 The **exact area** of Werkräume where we cowork will be updated in the **pinned comment on the event page**, as it is a public space and we cannot reserve a specific spot. **How to find Werkräume:** * **If you are starting from the Front Desk:** Find the large escalator behind the front desk.

Your update is much appreciated. 8. **All organizers are volunteers who are neurodivergent individuals.** We ask you to **be kind to us** and for your **support in making the event an enjoyable** for everyone. **Till then busy bees!**

Each other participant gets to ask him one question. 2. **Feedback Round** – The group provides feedback on communication, structure, and clarity. Constructive criticism is encouraged. 💡You will be asked: * **Light design problems** (high-level reasoning, not code) * **Behavioral questions** (“Tell me about yourself”, “Describe a challenge you faced...”) No need to prepare anything in advance — just bring curiosity and an open mind. 💡Note: location is the entrance to Monbijou park

In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** https://youtube.com/live/BltmWMH1zG0?feature=share
