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.

The event is part of our WEEKLY MEETUP SERIES. ---- Hey Badminton Enthusiasts! This meet-up is for all levels: beginners, intermediates and experts. Everyone is welcome to join, test their skills and have some fun together! The organiser will reserve courts in advance - PLEASE ONLY REGISTER IF YOU REALLY PLAN ON COMING (OR CANCEL ASAP IF SOMETHING CAME UP). We are meeting at about 07:50 pm near the reception by the lounge area (next to the courts). Come a bit earlier so you have time to change into workout/sports clothes. The locker rooms are free to use. Also, bring clean indoor sports shoes, your racket and a water bottle with you. There is also a drinking fountain available if you need to replenish your bottle. The organiser will be at the club about 5 min. ahead of time and pay for everyone - please bring if possible exact change and pay the organiser after the event! The fee for this event is 6€. It is possible to rent rackets from the club, if necessary (3€). Sometimes members have spare rackets - please ask in the comment section below! If you are joining our events for the first time, WELCOME! Let the organizer know that you are new and they will find a place for you. Don't worry, we are an open and friendly group. We are sure you will develop connections with the people in our community in no time! Without further ado - see you at our next event! 2G rules apply: geimpft or genesen. We will adapt our events according to the official regulations.

📢 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).

Thank you for visiting this event page! * Are you an advanced badminton player? If yes - WELCOME! * The earlier you sign up, the bigger your chance to reserve a place - once 9 other players have signed up already, you move to the waiting list. * Once the waiting list has 3 or more members, I will try to book an additional court, but no guarantees. I need to close the registration 24h before the event as I will then have to decide whether to cancel any court due to a shortage of players. You can still contact me if you want to play though. The fee per player will be €10.00 for 2 hours as the cost of both shuttles and court bookings have increased. But this should now cover also shuttles used during play. Please be on time as a curtesy to the other players. In addition, if you are on the players' list and don't come (i.e. no show), you will be automatically excluded from this group.

Join us for **two hours** of badminton! This event is open for all levels and ages! It is part of the club Sportunion Vienna Badminton Community.

Please bring a racket, sports clothes and shoes and a water bottle. We provide feather shuttles. You can also likely borrow a racket from one of our players if you need to.

**Note:** Kindly bring cash for any food/drinks purchases under 20 Eur, as the restaurant/cafe accepts card payments only for purchases above 20 Eur. This is a **free** event. Are you ready to practise your language skills? If you want to meet new friends (or the same friends you met at our other events) and practice all the languages you can speak, join us for a fun-filled evening! During this event, you have the chance to choose a Group and talk to people in: 1. **English** 2. **German** 3. **Italian** 4. **Spanish** 5. **French** Our most important rule: Please be respectful to others at all times.

**Latest Dojo Location!** **Knotty Pine Brewing** 1765 W 3rd Ave, Columbus, OH 43212 We're going to try a new dojo location for a few weeks and see how it works Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead. We're looking for speakers for our Monthly Meetups! Fill out the form if you are interested in presenting to the Python Community. https://forms.gle/ehSfUAC2WgR34Crq9

The topic for April is "Water" Speak Easy: true stories, told live. The idea is simple: an audience, an open microphone, and great stories. Hilarious, gripping, poignant- it's up to you. Audiences are invited to come to listen or come to tell as folks from all corners of Columbus offer their stories live on stage! Held at Wild Goose Creative's warm, intimate space, this night of tales occurs on the 3rd Thursday of every month. Doors open at 6:30 pm, show starts at 7:00 pm. Please arrive early if you want to tell, as we generally only have room for a limited number of tellers, and the sign-up sheet has a tendency to fill up fast. Formed around the idea that people need stories--they're what hold and draw us together--SpeakEasy celebrates the strangeness and commonness of being human. And in a world of smartphones, Facebook, Twitter, and more . . . it gives people a real, breathing, in-person way to connect. The night is geared for true stories of all kinds, taking the best tales told around kitchen tables, in darkened pubs, on the street corner, and at late-night parties and giving them an audience. Speak Easy is also a great outlet for performers, writers, and artists looking to share their favorite stories and perfect their skills. We strongly encourage tellers to please tell the story rather than read it so we keep within the spirit of good storytelling and stay engaged with the audience. All are welcome. Hang around after the show for a drink and build community!

Let's grab some coffee/food and share a morning chat! The East Market has an ample parking lot and outdoor and indoor seating. Grab a cup of coffee from Winston's Coffee & Waffles or on your way to East Market and meet us on the second floor - table behind or east of the elevator. Per what this group is about: "Everyone is welcome! International transplants to Columbus who want to improve language skills, Columbus residents who want to discuss international travel and culture, and anyone who enjoys getting together for good conversations."

While some are still meeting online, this is an in person event. Please note that we have attendees of all levels of speaking, including some native speakers. All are welcome! Also, as we meet at the same time and place each week, many don’t RSVP on the app, so we will likely have more attendees than noted here. Note: if you are asked to pay and upgrade the Meetup app, this is not necessary. You can ignore this and still attend our meetings. Find us on our [Facebook group](https://www.facebook.com/share/g/1EKw86WJCp/?mibextid=wwXIfr).
