パーティー

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.

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

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

Private Group. Closed to the Public Knowing ourselves and understanding our abilities is the first step toward wielding our gifts with control and accuracy. In subsequent classes we will verify and hone our talents with activities and discussion. These are hands-on workshops and participation is expected. The goal of our series will be to develop expertise in areas of particular interest such as mediumship, channeling, divination, healing and, etc.. Our ultimate directions will be determined by class members as we evolve. I look forward to sharing and discovering with you. - Cynthia

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus. Sponsored by [Transform Labs](https://www.transformlabs.com/services)
