After **"winter is coming"** we finally can say **"spring is coming"** to Vienna! As we had the AWSome GameDay Europe in March, we're now coming back to our **regular agenda**! We're visiting The Atelier at **Impact Hub Vienna** this time, thankfully to the sponsor **Bytesource**! *** 📍 **Location** The Atelier Impact Hub Vienna [Lindengasse 56, 1070 Wien](https://www.google.com/maps/place//data=!4m2!3m1!1s0x476d078cbc5cf79b:0x3e9197850789a772?sa=X&ved=1t:8290&ictx=111) 🕒 **When** **April 22th 2026** Doors open at 17:00 for networking, food & drinks. Talks start at 18:00. *** 🗓️ **Agenda** * **17:00 - 18:00:** Entry & Networking * **18:00 - 18:05:** Welcome and Introduction AWS Community Vienna * **18:05 - 18:10:** Welcome and Introduction to the sponsors (**Bytesource**) * **18:10 - 19:00:** **"Sales Copilot: Turn complex technical inquiries into clear, accurate offers in minutes, not hours!"** * **19:00 - 19:20:** Networking break * **19:20 - 20:00:** **"Beyond Vibe Coding"** * **20:00 – Open End:** Networking **"Sales Copilot: Turn complex technical inquiries into clear, accurate offers in minutes, not hours!"** *Speaker:* **Alexander Matev**, CISO at Bytesource *About the talk:* Sales CoPilot as a solution that helps teams turn complex technical customer inquiries into clear, accurate quotations much faster, reducing turnaround from hours to minutes. The business problem: technical sales requests are slow, difficult, and error-prone when handled manually. The Solution: Our Sales CoPilot interprets complex requirements, works with documentation and technical data, and supports offer preparation. Technology foundation: strong emphasis on AWS as the enabler, plus AI/LLM-driven processing. Architecture choice: a set of core AWS services to deliver both the user-facing application and the AI-powered data processing pipeline. Amazon S3 stores uploaded product datasheets and hosts the frontend assets, while Amazon CloudFront accelerates and securely delivers the web interface to users. Incoming application traffic is routed through an Application Load Balancer (ALB) to containerized services running on Amazon ECS, which handle both backend business logic and document ingestion tasks. For AI capabilities, Amazon Bedrock is used in two places: to extract and transform structured information from PDF datasheets, and to power the agentic logic behind the application. Persistent structured data is stored in Amazon Aurora PostgreSQL, which supports read/write operations from the backend. Together, these AWS services provide a scalable, cloud-native architecture for hosting, processing, AI enrichment, and application delivery. ### **"Beyond Vibe Coding"** *Speaker:* **Sergio Lopez-Gehler**, Solutions Architect @ AWS AI agents are changing how engineers write, test, and ship code. This talk explores what agentic coding looks like in practice — the workflow, the tradeoffs, and the tools that make it work. We'll cover how to collaborate effectively with AI agents: prompting, reviewing, iterating, and knowing when to take over. We'll look at what changes when development gets significantly faster — testing strategies, CI/CD pipelines, and team coordination all need to keep up. Then we'll introduce Kiro, an agentic IDE that uses spec-driven development, steering rules, and hooks to let engineers define how the agent operates within their codebase. We'll also look at AWS DevOps Agent — an autonomous operations teammate that correlates metrics, logs, and deployment history to investigate incidents and identify root causes before you even open your laptop. *** 💛 **Sponsors:** * **Bytesource** - [https://bytesource.net/de/](https://bytesource.net/de/) *** 📌 **RSVP now** and invite your colleagues to celebrate, learn, and connect with the AWS community at **Impact Hub Vienna**!

Hallo liebe Java User Group Mitglieder! Diesmal haben wir Nils Hartmann mit seinem Talk zum Thema "**[Spring Modulith](https://spring.io/projects/spring-modulith)**" zu Gast. Wir freuen uns euch zu sehen (virtuell oder vor Ort). * 18:00 Uhr: Einlass * 18:30 Uhr: Talk * ab 19:30: Ausklang des Abends Dank an [qSkills](https://qskills.de/) für Location, Bier und Pizza! \-\-\- Oft sollen Anwendungen in entkoppelten Modulen entwickelt werden, um Ordnung und Struktur in unseren Code zu bekommen und darüber Wartbarkeit zu garantieren. Microservices stellen dafür einen sehr konsequenten Ansatz dar, können aber auch eine hohe Komplexität mit sich bringen. “Monolithen” hingen sind vergleichsweise bequem in der Entwicklung, stehen aber im Verdacht, schnell zu einem unübersichtlichen “Big Ball of Mud” zu werden. Diesem Problem versucht “Spring Modulith” entgegenzutreten. Damit werden Spring Boot-Anwendungen in einer gemeinsamen Codebasis entwickelt (”monolithisch”), innerhalb dieser werden aber Module definiert ("modulitisch"), deren korrekte Verwendung anhand von Architekturregeln kontinuierlich überprüft und sichergestellt wird. Außerdem erweitert Spring Modulith das Spring-eigene Eventsystem, um auch zur Laufzeit für eine Entkopplung der Module zu sorgen. In diesem Live-Coding-Vortrag möchte ich anhand praxisnaher Beispiele eine Einführung in Spring Modulith geben und mit euch diskutieren, welche Konsequenzen sich für unsere Anwendungen daraus ergeben und für welche Szenarien dieser Ansatz besonders geeignet ist. \-\-\- Dein Vortrag bei der Java Usergroup Nürnberg! Hast du dich in letzter Zeit in deinem Projekt oder privat mit einem interessanten Thema beschäftigt? Vermutlich ist das nicht nur für dich selbst interessant! Hast du Lust, selber einmal einen Vortrag bei der Java-Usergroup Nürnberg zu halten? Wir sind nicht nur auf Java-Themen fokussiert, sondern beschäftigen uns gern mit und um alles über Software Entwicklung und IT. Wir wollen bei der JUG nicht nur bekannten Speaker\*innen eine Plattform geben und die neuesten State-of-the-Art Technologien vorstellen. Wir freuen uns auch besonders, wenn wir Themen aus unserem technologischen (Arbeits-)alltag Raum geben zu können. Melde dich gerne bei uns, wenn du dazu Lust hast, wir geben wenn gewünscht gerne auch Hilfestellung bei der Vorbereitung!

**Hey everybody!** Do you want to code together, share your projects, or just hang out in a creative atmosphere? Then join us at the **Coding Club @ Jo&Joe Hostel**! We usually start with a short introduction round so everyone can get to know each other. After that, you can: * share your achievements or pet projects (informal, just at the table) * get feedback or inspiration from others * or simply work on your own project alongside the group Bring your laptop (or any device you like to code on) if you want to actively work. Or just come by to connect and get inspired. Please try to be on time so we can kick things off together. Looking forward to seeing you there! 🚀

Arnold Schönberg (1874–1951) was one of the most significant figures in the creative world in the first half of the 20th century. Following in the tradition of Mozart, Beethoven, Brahms, and Mahler, the Austrian (and, after his immigration to New York and later Los Angeles, also US-American) composer, music theorist, teacher, and writer reshaped the practice of harmony in classical music. Some of Schönberg’s most famous contributions were the development of his twelve-tone-method and his attention to sound color (Klangfarbe), both of which strongly influenced generations of composers up until today. But Schönberg’s creative world goes beyond music. He was a designer, painter, inventor, and systems thinker: building tools and furniture, binding books, designing stage sets and costumes, inventing machines, and even building his own chess set, for four players. In this meetup, we explore Schönberg through a UX lens: what can his way of thinking, making, and problem-solving teach us about design, tools, and user experience today? We will also look at the museum and concert space as an experience that unfolds through the perception of an audience. The [Arnold Schönberg Center](https://schoenberg.at/) is a repository of Schönberg's archival legacy. Director Dr. Ulrike Anton will provide an introduction to the Arnold Schönberg Center. User researcher Dr. Franziska Brunner will give us a guided tour and lead a discussion of the exhibition. Arnold Schönberg's estate is on [UNESCO’s Memory of the World Register](https://www.unesco.at/en/communication/documentary-heritage/memory-of-the-world-in-austria/arnold-schoenberg-estate), recognized for its global importance as a documentary heritage. After an afternoon in the museum space from 3:00–6:00 p.m.. We also invite you to attend an [in-house concert at 6:30 p.m](https://schoenberg.at/en/events/upcoming-events/3793/loops-from-other-planets)., followed by dinner. 🎻 🍽️ * The €18 concert price includes entrance to the exhibit. (Entrance to just the exhibit without the concert costs € 6.) * Admission for both the museum and the concert is free for those under 26 years old. * Dinner afterwards is optional, and everyone will cover their own meal. *Photo: Replica of Schönberg's study room © Johannes Böck*

Whether you’re a researcher, a "Clawdbotler," a founder, or a policy innovator, this is your space to connect. We’re breaking down the silos between research, product, and engineering to spark real discussions before the workday even begins. * **When:** April 24th, 8:30 AM * **Where:** Cafe Museum - Table reserved under **"Cristian Hofmann / AI Austria"** * **Hosts:** Cristian, Amin, and Ruben * **Cost:** Order breakfast at your own expense Space is limited! 👉 **RSVP only if you’re 100% sure you can make it.**

Our co-organizer Ursula Laa will be giving a talk orgranized by the Young Statistician Forum (FJS), and you are welcome to join! Expect a technical tour of visualisation tools for multivariate and high-dimensional data in R with practical examples! **ℹ️ Abstract** Statistical graphics are central to exploring and modeling complex data. As dimensionality increases, uncovering structure and dependencies becomes more challenging. This presentation gives an overview of practical tools for visualizing multivariate data, from strategic use of scatterplots and scatterplot matrices to linear and nonlinear projection methods. Special emphasis will be placed on tour methods—animated sequences of linear projections—that reveal clustering, outliers, and nonlinear relationships. All graphics will be demonstrated in R, with code to reproduce the results. **🗺️ Location** Seminarraum 16 3rd floor Oskar-Morgenstern-Platz 1, 1090 Vienna Use this [floor plan](https://event.univie.ac.at/fileadmin/user_upload/d_event/Dokumente/Raummanagement/PLAENE_NEU/Plaene_OMP/UEbersichtsplaene/01__3OG_Uebersicht.pdf) to help locate the room.

Welcome to our cozy **The Psychology and Personal Growth Circle** which is part of the Social Book Club! We will meet to discuss the book “**Antifragile**" (426 pages) written by Nassim Nicholas Taleb. The idea is to connect with like minded readers that love to grow and get to know themselves better through reading and especially applying knowledge from books. We meet up once a month and talk about our progress applying knowledge from a certain book and our experience. The event will take place at the volunteer organisation **MUT**. It is an organisation to supports humans, animals and the environment especially in Vienna. MUT or the Social Book Club look forward to some donation to cover the cost of this event. If you would like to help, please bring some cash with you. Book Description: In The Black Swan Taleb outlined a problem; in *Antifragile* he offers a definitive solution: how to gain from disorder and chaos while being protected from fragilities and adverse events. For what he calls the "antifragile" is one step beyond robust, as it benefits from adversity, uncertainty and stressors, just as human bones get stronger when subjected to stress and tension. See you then! All the best Sebastian
