C & C++

📢 Main event starts at 18:30 CET René has a passion for collecting unusual code constructs and presenting them anonymously to an interested audience. Any resemblance to existing code is purely coincidental 🤭. There will be plenty of opportunities to puzzle over the quirks of C++, whether you are an experienced developer or just curious about the language. The challenges might drive you crazy if you tackle them alone, but working together as a group, you just might make it through. The main goal is to enjoy the challenge, not take things too seriously, and have some fun along the way. 🧠 All you need is your brain - no notebooks needed. 🪙 We appreciate any **voluntary donations** on-site. ⏱️ Arrive early for pre-socializing—simple snacks and drinks will be provided. 🍕 After the event, we will relocate to a pizzeria (at your own expense).

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.

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** GitHub Copilot is powerful, but what if you could scale from a solo AI assistant to an entire team of specialized agents working in parallel? 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

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)
