Human Design isn’t just theory, it’s a map back to your natural way of operating. Stop pushing against the grain and start living in alignment. This 2 hour long interactive workshop is designed to bridge the gap between “knowing” and “doing.” We’re skipping surface-level small talk to explore the deeper layers of human nature. Whether you’re completely new to Human Design or already familiar with it, you’ll find a supportive, English-speaking community ready to help you trade resistance for flow. *** ## The Agenda During this session, we will explore: * **The Origin of Human Design** – Where it comes from and how this system was created * **What Human Design Is** – The foundations of the system and how it works * **The Human Design Types** – Understanding the different energy types and how they move through life And to make things interactive and fun: 🎟 **Human Design Lottery** At the end of the workshop, 1–2 participants will be selected to receive a **live mini chart reading**. After the workshop, we’ll open the space for **networking**, connection, and deeper conversations in a relaxed atmosphere. *** ## Your Toolkit * **Your Stats:** Birth date, exact time, and location * **A Notebook:** For those “aha!” moments you’ll want to remember * **The Vibe:** An open mind and a healthy dose of curiosity *** ## Investment €15 per person Early Bird: €10 *** ## The Venue & After-Vibes We’re gathering at **Zoku Vienna**, a creative hub in the heart of the city. Since it’s Wednesday, Zoku features live music in the evening. You’re warmly invited to stay after the workshop, enjoy the tunes, and connect with the community in a relaxed atmosphere. *** ## A Note on Attendance Please only sign up if you are certain you can attend. We coordinate seating directly with the venue based on our numbers, so an accurate headcount is essential to ensure we have the perfect space for everyone.

Agenda: 18:00 Doors Open 18:20 Intro/Sponsor Welcome 18:30 Doors Closed! (the reception on the ground floor will not be served anymore.. come early!) 18:30 **Here we go again: Java26 / Dominik Dorn** 19:30 Break, Food, Drinks 19:55 Raffle 20:00 **Java-UIs modernisieren ohne JavaScript — Webswing & webforJ in der Praxis / Stephan Wald** 21:00 Networking Talk 1: **Here we go again: Java 26** We'll explore everything new in Java 26! **Java-UIs modernisieren ohne JavaScript — Webswing & webforJ in der Praxis / Stephan Wald** Ihr habt eine Swing-Anwendung. Oder Eclipse RCP. Oder Oracle Forms. Das Management will sie „im Browser". Der Reflex: React-Frontend, REST-APIs, JavaScript-Entwickler einstellen, zwei Stacks pflegen. Aber muss das sein? Es gibt inzwischen mehrere Java-native Ansätze für Web-UIs — ihr kennt vermutlich einige davon aus früheren Meetups. Die meisten setzen voraus, dass ihr eure UI von Grund auf neu schreibt und bestehenden Code hinter REST-APIs kapselt. Unser Ansatz ist ein anderer: Wir zeigen einen **zweistufigen Migrationspfad**, der mit der unveränderten Bestandsanwendung im Browser startet und die Modernisierung dann Bildschirm für Bildschirm vorantreibt — ohne den Betrieb zu unterbrechen und ohne eine zweite Technologie einzuführen. Im ersten Schritt kommt **Webswing** zum Einsatz — eine Laufzeitumgebung, die Java-Desktop-Anwendungen (Swing, JavaFX, SWT, Eclipse RCP) unverändert im Browser bereitstellt, indem sie auf Toolkit-Ebene in die AWT-Pipeline eingreift und das Rendering über HTML5 Canvas und WebSocket an den Client streamt. Im zweiten Schritt zeigen wir **webforJ** — ein Open-Source-Framework (Apache 2.0), mit dem moderne Web-UIs komponentenbasiert in purem Java entstehen: Routing, Data Binding, responsive Layouts, Spring-Boot-Integration — ohne eine Zeile JavaScript. Der technische Kern des Abends: * **Webswing unter der Haube:** Wie die Custom-`Toolkit`-Implementierung funktioniert, was auf Server- vs. Client-Seite passiert, und wo die Latenz-Grenzen liegen * **webforJ-Architektur:** Server-seitiges Component Model auf Basis von DWC (Dynamic Web Client) Web Components, Event-Handling im Vergleich zum Swing-Listener-Modell, Layout-System (`FlexLayout` vs. `BorderLayout`) * **`WebswingConnector`:** Die Integrationsbrücke — wie eine webforJ-Anwendung eine Webswing-Session einbettet und bidirektionale Kommunikation zwischen Legacy-Swing-Code und modernem UI ermöglicht * **Live-Code:** Vom minimalen webforJ-Hello-World bis zur Hybrid-App mit eingebettetem Swing-Panel — wir bauen es vor euren Augen * **Ehrliche Trade-offs:** Wann dieser Ansatz passt, wann nicht — und was er im Vergleich zu einem reinen UI-Framework-Wechsel bringt und kostet Wir bringen einen Praxisbericht mit: Ein niederländischer ERP-Anbieter hat mit einem kleinen Team in vier Monaten die ersten Web-Module produktiv geschaltet — ohne JavaScript-Expertise im Haus. **About the Speaker** Stephan Wald entwickelt seit über 35 Jahren Enterprise-Software, seit über 20 Jahren in Java. Seine Erfahrung umfasst C++, C#, mehrere Business-Basic-Dialekte sowie heute primär Java. Als Head of Development und Mitglied der Geschäftsleitung bei BASIS International Ltd. (Albuquerque, USA) verantwortet er die Entwicklung des webforJ-Frameworks, eines Single-Stack-UI-Frameworks für geschäftskritische Java- und Kotlin-Anwendungen in mittelständischen und großen Unternehmen weltweit. Parallel baut er mit [SkillsPilot.de](http://skillspilot.de/) eine KI-gestützte SaaS-Plattform im HR-Consulting, die mit namhaften deutschen Unternehmen mit bis zu 20.000 Mitarbeitenden wächst. Speaker auf der JavaOne 2026.

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD
