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.

**ACHTUNG! Wir treffen uns dieses Mal auf Grund von Bauarbeiten bei der U4 Station Friedensbrücke Ausgang Straßenbahn 5 und 12!!!** **Walk & Talk** Willst du auch mehr Bewegung in dein Leben bringen? Und dich dabei noch gut unterhalten, so dass die Zeit verfliegt? Dann bist du hier genau richtig, denn mir geht es genauso. Alleine ist langweilig und die Zeit vergeht nicht, daher hab ich mir Walk & Talk überlegt. Inspiriert wurde ich durch die Walk & Talk Gruppe in Hamburg, wo ich mehrere Male dabei war als ich in Hamburg lebte. Unterschiedliche Menschen treffen sich einmal in der Woche für einen flotten Spaziergang und unterhalten sich dabei. Ich liebe es neue Menschen kennenzulernen und auch bekannte Gesichter wiederzusehen, dann geh ich ganz nebenbei und das macht auch noch Spaß.😊 **Walk:** Wir brauchen einfach regelmäßige Bewegung und ich weiß selbst, wie schwierig es ist, diese in den Alltag zu integrieren. Deshalb ist dieser Walk genau richtig. Nach diesem Spaziergang fühlst du dich einfach wohl, fit und entspannt. **Talk:** Das Reden kommt ganz von selbst beim Gehen. Du kannst über alles reden, egal, ob privates oder berufliches, alles was sich ergibt ist willkommen. Und wenn du keinen Bock aufs Reden hast, dann gehst du alleine, auch das ist völlig in Ordnung. **Wie das ganze abläuft:** * Die Teilnahme ist völlig kostenlos. * Wo: U6 Spittelau (im Freien), Richtung Donaukanal, Ausgang Josef-Holaubek-Platz, direkt vor dem Fernwärme-Turm (https://maps.app.goo.gl/XwAayz4FQe2EW8WK9) * Wann: Wir treffen uns dienstags um 13 Uhr, egal, ob bei Regen, Sturm und Kälte oder bestem Sonnenschein – Walk & Talk findet nahezu JEDE Woche statt außer ich bin mal im Urlaub. * Wir starten pünktlich und beginnen mit einer kurzen Vorstellungsrunde. * Wie gehen am Donaukanal entlang von Höhe Spittelau bis zum Schwedenplatz und zurück. * Ca. 7 Kilometer sind wir unterwegs und unterhalten uns dabei mit interessanten Menschen. Dabei kannst du neue Bekanntschaften schließen, dich inspirieren lassen, von Projekten erzählen oder einfach nur smalltalken und die frische Luft genießen. Alles ist erlaubt. * Nach ca. 1,75 Stunden sind wir wieder am Ausgangspunkt zurück. * Bei einer Teilnahme von über 5 Personen gehen wir in Paaren und wechseln diese alle 10 Min. Wenn du aber lieber alleine gehst, ist das auch vollkommen in Ordnung. * Für alle, die einfach mal etwas Neues ausprobieren wollen. **Bist du bereit?** Dann komm mit! **Start bei U6 Spittelau Ausgang Donaukanal** Nochmal: um **PUNKT 13.00 Uhr dort sein**, denn **nach kurzen Vorstellungsrunde gehen wir gleich los. Sei pünktlich, denn die Gruppe wartet nicht.** Du musst nichts vorbereiten oder dich gar anmelden, komm einfach vorbei. Ausreden gibt es nicht. Geh mit und freu dich auf eine tolle neue Erfahrung. **Wer macht es?** Ich bin Marie Meyer-Marktl und Ideengeberin, Host und Organisatorin von Walk & Talk. Ich unterstütze seit 2019 Menschen dabei Freude ins Arbeitsleben zu bekommen und bin Business und Life Coachin. „Strahle, wenn du an deine Arbeit denkst“, ist meine Vision für jedermann und jedefrau. Privat merkte ich, dass ich endlich wieder mehr Bewegung brauche – und das klappt am besten gemeinsam mit anderen Menschen. Sei dabei bei Walk & Talk und bring Bewegung in dein Leben. **Do you speak English? Then welcome to Walk & Talk!** This event is suited for all people who like to connect to other people and like to walk. The beauty of this regular event is that you are in the nature and you walk around 7 kilometers. In the meantime, if you feel for it, you talk, if not, you just walk. You do something for your health, get to know new people and you will feel much better. It’s FREE, all you need to do is to show up this Tuesday at no later than 1 pm at the U6 Spittelau exit to Donaukanal.

[https://t.me/cinetour](https://t.me/cinetour) Boston medical resident Susan Wheeler (Geneviève Bujold) becomes suspicious when her friend (Lois Chiles) is left in an irreversible coma after a routine procedure. Once she uncovers evidence of other patients being left in comas after undergoing procedures in the same operating room, she fears a conspiracy is afoot. When her physician boyfriend, Mark Bellows (Michael Douglas), is skeptical about her findings, Susan must go it alone to uncover the horrible truth. \*\*\* *HOW* **If you can't find us before/after the movie, write me a PM (Farit, the host) or post a message to this event, I monitor it during the meetup and will pick you up.** We meet at 18:30 at Breitenseer Biergartl (Huttengasse 1), and and shortly before the movie we go together to the theatre.

Du sprichst schon gut Deutsch (B2–C1) und möchtest einfach öfter reden? Dann bist du hier genau richtig. Wir treffen uns in kleinen Gruppen in gemütlichen Wiener Cafés und plaudern entspannt über alles, was uns gerade interessiert, oder über ein vorher vereinbartes Thema. Auch Muttersprachler:innen sind herzlich willkommen. Die kleine Runde ist bewusst gewählt: So hören wir einander gut und kommen leichter ins Gespräch. 👉 **Ein paar Infos, damit alles gut läuft:** – Bitte verwende deinen echten Vornamen und ein Profilfoto. – Melde dich nur an, wenn du wirklich kommen kannst. – Falls etwas dazwischenkommt, sag bitte rechtzeitig ab. – Die **genaue Location** wird am Vorabend des Treffens an die bestätigten Teilnehmer:innen kommuniziert und in den Kommentaren sichtbar sein. – Wer ohne Absage nicht erscheint, kann leider nicht in der Gruppe bleiben. Wir möchten die Treffen zuverlässig und angenehm für alle halten. Ich freue mich auf entspannte Gespräche und eine nette, motivierte Runde! 😊

Weekly screenings from a large archive of many of the most significant, yet seldom seen and rarely accessible cinematic masterpieces in the history of film - from its earliest beginnings to the present day. Screenings are in original language, if English, or original language with English subtitles. Films are selected democratically on the inspiration of a brief pre-screening discussion. The selected title is typically a "neglected gem" that most of us discover together for the first time. Individual taste is not a criterion and all participants are expected to put the interests of the group as a whole above personal preference or prejudice. In this sense, the emphasis is on openness, exploration, and surprise. Each screening is followed by an in-depth group discussion, led and moderated by the curator. WARNNG: FilmStory is not just about watching movies! Rather, it's a socially responsible, intellectual engagement, involving an organic approach to group study of film language, philosophy, art, history, politics, and technology. In this sense, the film is always merely the current highlight in an explorative, ongoing group discussion. **FilmStory** is a members-only series that involves a closely knit community of cinephiles. Events take place every Sunday in a comfortable, private setting with limited capacity. Participation is reserved primarily for regular members, but we're always ready to make new friends! Non-regular members may request to meet the community and, upon acceptance as a "new joiner," are welcome to participate in one event, according to space availability. New joiners are asked to make a €6 member dues contribution in advance of the requested date. New members receive a message of confirmation and the address of the Living Room in 1080 Vienna upon receipt of their dues contribution. **FilmStory** is presented and hosted by **[KulturSalon Wien](https://www.meetup.com/kultursalon-wien/)**.

Main Library, Meeting Room 3B Join us for a welcoming evening of reflection, gentle music, and meaningful conversation. We’ll begin with a short grounding moment, followed by a brief reading from spiritual or philosophical traditions, and an open reflection circle where participants can share (or simply listen). Libera Animae is an interfaith community focused on inner growth, creativity, and authentic connection. All backgrounds are welcome.

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.

**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

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

Pay attention! We’re delaying a week for those of you who may be on Spring break and/or celebrating the holiday. Ok, no pancakes, but waffles-a-plenty. Join the local UX and Digital Design community for a casual monthly breakfast. Look for us upstairs!

**Our April novel is: *The Hong Kong Widow* by Kristen Loesch** **This month’s novel blends gothic atmosphere with historical fiction and chilling horror, set against the haunting backdrop of China. The book is 368 pages in print and 10 hours and 42 minutes on audiobook.** In 1950s Hong Kong, Mei is a young refugee of the Chinese Communist revolution struggling to put her past in Shanghai behind her. When she receives a shocking invitation—to take part in a competition in one of the city's most notorious haunted houses, pitting six spirit mediums against one another in a series of six séances over six nights, until a single winner emerges—she has every reason to refuse. Except that the hostess, a former Shanghainese silent film star, is none other than the wife of the man who once destroyed Mei’s entire life. It is promised the winner will receive a fortune, but there is only one prize Mei wants: revenge. Decades later, the final night of that competition has become an infamous urban legend: The police were called to the scene of a brutal massacre but found no evidence, dismissing it as a collective hallucination. Mei knows what she saw, but now someone else is convinced they know what she did. She must uncover the truth about the last night she ever spent in that house—even if the ghosts of her past are waiting for her there. . . .

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)
