Agenda: 18:00 Doors Open 18:20 Welcome+Orga stuff 18:30 Multithreading under the lens - Marco Sussitz + Christian Lutnik / dynatrace 19:30 Break, Networking 19:55 Raffle 20:00 Own Your Domain Before It Owns You - Philipp Seifert-Kehrer + Leo Bowen Wang / Posedio 21:15 Networking **Multithreading under the lens: what is VMLens and how can it help you? - Marco Sussitz & Christian Lutnik, dynatrace** I am sure that we all know how difficult it can be to write correct multithreaded code. Race conditions, deadlocks, and memory visibility issues can introduce bugs into your code that are nearly impossible to find in your unit tests. In this talk, we will see how VMLens can help you find those bugs in your program. And how you're able to write unit tests that can show you if your multithreaded code is incorrect. We will also take a look at how VMLens is even able to do so. **About Marco Sussitz** Marco Sussitz is an engineer at Dynatrace who lives at the boundary of Java and C++. He writes JVMTI agents, instruments bytecode, and digs into JIT, memory, and thread behavior. You'll often find him sorting out class loaders or, reading the spec longer than he should. Before Dynatrace, he worked on cloud video encoding with FFmpeg. Off hours he's bouldering or in the mountains. **About Christian Lutnik** Christian has been programming since his early teenage years. In this time, he has developed a passion for efficient code that does not crack under pressure. Starting with the most basic Android games even before Unity was cool, he quickly adapted to new technologies. He is now employed at Dynatrace, a company that is just as convinced as he is that software needs to work perfectly. There, he works together with the open-source community and an amazing team on making feature flagging fun for everyone with OpenFeature. **Own Your Domain Before It Owns You** It's bugs that make Software tumble, but it's blurred boundaries that make it collapse for good. In case of doubt, experts will simply slap the "Domain-Driven-Design" label around, but what does that even mean and how can we actually put something like that into practice? In this talk we will take a look at what Modularity across your Domains actually boils down to, why it even is a necessity to stay sane and how to actually implement it into your Java systems. We'll take a look at how bounded contexts should be your best friends as a developer and why everything is an API. Expect fun anectdotes from mistakes we made in the past, a philosophical deep dive into organized coding and practical guidance for building systems that are not even that terrible to maintain. **About Philipp Seifert-Kehrer** Philipp is an Engineer with a knack for creating full-fledged Software solutions, always considering the bigger picture and never forgetting the human element. Having been around the block, covering industries from finance to retail and technologies from legacy to cutting-edge — Philipp has seen it all. That taught him that ‘fancy’ is hardly ever better and solidified his no-BS approach to problem-solving. Outside of work, he loves spoiling his cats and carrying his baby-daughter around town. **About Leo Bowen Wang** Leo is one of the newer additions at Posedio bringing profound experience as a Java Software Developer with him. Equipped with a next-man-up mentality almost to a flaw there is no issue he won’t tackle immediately by rolling up his sleeves and getting at it. Neither Spring, Containers, CI/CD nor scalable systems such as microservice architecture are foreign concepts to him and he is adding to his relatively young skillset on a daily basis. In any case keep a close eye on him or even an ear when he’s on his side hustle as a DJ.

PCE - "Philosophic Conversation in English" is a discussion event in English language which focuses on psychology, philosophy, self-consciousness and self-realization. The conversation is based on inclusive discussion rules. We will meet at at a restaurant where we will have a private room exclusively reserved for our event. At the beginning we will choose the topic to discuss. Everybody can suggest a topic. Then we will vote what to discuss. The person who suggested the winning topic will then explain his idea of the topic. Afterwards everybody gets his/her chance to make a statement. But you can also decide to remain silent and only listen, if you prefer that. We have a time limit for statements, so that everybody has enough time to speak. It is not allowed to interrupt somebody who is speaking. After a statement everybody can ask a question and the speaker will answer. After the first part there will be a 10 minutes break before we start the second part. Everybody is welcome to our event: We are interested in your thoughts and opinions! It is no problem if you arrive late and you can also leave whenever you want.

## [BOOK HERE!!!](https://www.universe.com/events/english-stand-up-comedy-show-monday-night-laughs-the-comedy-pub-tickets-0NML7Q?ref=MeetUp) Monday Night Laughs: Vienna’s English stand-up open mic! Watch & perform every Monday at The Comedy Pub. Free entry, cozy vibe, endless laug Vienna’s English Stand-Up Comedy Open Mic – Every Monday at The Comedy Pub ## 😂 Mondays Don’t Have to Suck The weekend might be over — but the laughter doesn’t stop. Welcome to **Monday Night Laughs**, Vienna’s cozy and community-driven **English stand-up comedy open mic**, where locals, expats, and travelers come together to kick off the week with big laughs and good vibes. Every Monday night, *The Comedy Pub Vienna* turns into a creative playground for comedians and comedy lovers alike. Whether it’s your first time at a show or your tenth, you’ll feel right at home. Forget Netflix. Forget the Monday blues. This is your weekly reminder that laughter fixes everything — especially on a Monday. ## 🎭 What Is *Monday Night Laughs*? It’s not a fancy showcase or a big-ticket headliner night. It’s something much better — it’s *real*. Here, the mic is open, the drinks are cold, and the laughter is honest. You’ll see comedians from all over the world — from total beginners testing their first five minutes to experienced performers working out new jokes for their next tour. No two shows are ever the same. One moment you’ll hear a joke about Austrian bureaucracy, the next about dating disasters in Spain or cultural shocks in Tokyo. It’s raw, spontaneous, and absolutely unpredictable — the way live comedy is meant to be. And because it’s all happening in English, the night draws a wonderfully mixed crowd: locals, internationals, and everyone in between. ## 🎙️ For Performers If you’ve ever thought, *“I could do that,”* this is your sign. *Monday Night Laughs* is one of Vienna’s most supportive and encouraging open mics for new comedians. No judgment, no pressure — just a room full of people who love to laugh and want you to succeed. It’s the perfect place to try stand-up for the first time, or to test new material before your next big show. The vibe is friendly, relaxed, and full of creative energy — comedy at its purest form. Sign-up is open before the show — come early, grab a drink, and put your name down. Who knows? You might be the next crowd favorite. ## 🎤 For the Audience If you just want to watch, you’re in for a treat. This is one of Vienna’s most authentic live experiences — a place where you can laugh, relax, and see the future stars of stand-up before they blow up. You’ll witness comedy in its rawest form: jokes being born, ideas taking shape, and performers finding their voice. Sometimes it’s perfect, sometimes it’s weird — but it’s *always* fun. Grab a beer, find a seat, and enjoy a night full of unpredictable laughter. ## 🍻 The Atmosphere The Comedy Pub isn’t just a venue — it’s a community. It’s the heart of Vienna’s growing stand-up scene, a space where people come together to connect, perform, and laugh without judgment. The audience cheers each performer, the comedians support one another, and the whole night feels like hanging out with friends who happen to be hilarious. It’s the kind of Monday night you’ll want to make a tradition. ## 📍 The Venue: The Comedy Pub Vienna 📍 **Kettenbrückengasse 7, 1050 Vienna** Nestled in the heart of Vienna’s 5th district, *The Comedy Pub* is the city’s only dedicated stand-up comedy club — a cozy Irish-style bar with warm lighting, a friendly crowd, and the perfect stage for laughter. 🍻 A full bar with great drinks 🎭 Intimate setting with front-row energy 🌍 A melting pot of locals, expats & travelers 🪑 First come, first seated – so come early! ## 📅 Event Details 📆 **Every Monday** 🚪 **Doors open:** 19:30 🎤 **Show starts:** 20:00 📍 **The Comedy Pub**, Kettenbrückengasse 7, 1050 Vienna 🗣️ **Language:** English 💶 **Entry:** Free entry – donations welcome (if you laugh, you pay in karma… or cash 😉) ## ✨ Why You’ll Love It Because this is what real comedy feels like. No lights, no filters, no fake laughs — just honest jokes, good people, and that unbeatable live energy that you can’t stream. **Monday Night Laughs** is more than a show — it’s a community, a creative space, and the friendliest way to start your week in Vienna. So come for the comedy, stay for the connections, and leave with sore cheeks from laughing. Monday Night Laughs: Vienna’s English stand-up open mic! Watch & perform every Monday at The Comedy Pub. Free entry, cozy vibe, endless laughs. #MondayNightLaughs #ComedyVienna #OpenMicVienna #StandUpVienna #EnglishComedyVienna #TheComedyPub #ViennaEvents #ViennaLaughs #FreeComedyVienna #ViennaNightlife #ComedyClubVienna #ExpatsInVienna #FunnyVienna #ViennaThingsToDo #LiveComedyVienna #InternationalComedy #ViennaLOL #MondayComedyVienna

Clear format, easy flow, and a professional office-style environment. 💎Price 10€ (cash) and order a drink 🤝 Who it’s for: Entrepreneurs, freelancers, startup founders, managers, and professionals from different industries who want to connect, exchange ideas, and explore collaboration opportunities. ⭐️ The atmosphere: Focused, respectful, and business-oriented. Come for the networking. Stay for the conversations. Leave with new contacts — and new opportunities 💬✨

📢 Main event starts at 18:30 CET ⚠️ Different location - near U4 Heiligenstadt This time, we welcome Fridtjof Sterna as our main speaker! When you design function APIs, how do you choose parameter types? C++ offers many ways to pass objects to functions, but choosing the right parameter types for an API often still feels like guesswork. We learn the mechanics and rules, yet rarely step back to ask the fundamental questions that should guide our decisions. In this talk, we revisit parameter passing from first principles. Starting from intent rather than language features, we view a function call as a negotiation between caller and callee, with ownership and mutability as the two key questions at the boundary. This perspective reframes value categories as evidence, demystifies std::move, and leads to a practical decision guide for API design. The goal is to provide a mental model that helps both learners and experienced developers reason more confidently about C++ code. Before the main talk, we'll briefly present our user group to newcomers, and share some news about the world of C++. \- 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 [Köö Q19](https://www.billardcafe.at/de/lokale/k-oe-oe-q19-kreilplatz.html) (at your own expense). \- We thank our host\, [42 Vienna](https://www.42vienna.com)!

After the quiet time of the year, let's jump into 2026 with the first edition of the Cloud Native Vienna Meetup! We are back with two deep-dive talks and plenty of time to reconnect with friends in the Viennese cloud native community. A big thank you to **Triscon** for hosting us and providing food and drinks! The meetup will take place at the **Impact Hub Vienna** (Lindengasse 56, 1070 Vienna). **Agenda:** * **17:30:** Doors Open & Networking * **17:55:** Welcome from the Organizers * **18:00:** **Talk 1:** Roman Ferstl – **Break it till you make it - Pushing systems to their limits with load and performance testing** * **18:45:** Break & Refreshments * **19:00:** **Talk 2:** Stephan Kraft & Philipp Bergsmann – ***Multi-factor authentication for Workload Identities w/ SPIFFE & SPIRE*** * **19:45:** Open Networking We look forward to seeing you there! \-\-\- **Talks:** Roman Ferstl (Triscon) **Break it till you make it - Pushing systems to their limits with load and performance testing** Every system has a breaking point. The trick is finding it before your users do. In this talk, Roman Ferstl explores how load and performance testing can be used not just as a checkbox activity, but as a detective’s toolkit for uncovering hidden bottlenecks, weak links, and unexpected system behaviors. Along the way, he will explain the key principles of effective load testing, demystify how the underlying tools actually work, and highlight widely used open-source and commercial options that attendees can try out themselves. To bring these ideas to life, Roman will run a live demo in a cloud-native environment: flooding a Kubernetes cluster with load, watching pods scale up in real time, and observing what really happens when theory meets traffic. You’ll leave with both practical techniques and a front-row seat to systems pushed to their limits—and beyond. Bio: Roman Ferstl is the founder of Triscon, the go-to company for performance engineering. With an MSc in Astrophysics and a background as a software developer, Roman has always been drawn to solving complex problems. After several years in software engineering, he launched Triscon in 2018, building it into a well-established specialist in making systems faster, more reliable, and more resilient. At Triscon, he and his team pioneer new approaches in performance monitoring and engineering—from automating test design to embedding performance tests seamlessly into CI/CD pipelines. Roman is particularly passionate about going beyond traditional load testing by leveraging modern observability solutions to uncover not just symptoms, but the true root causes of performance bottlenecks. When systems bend under pressure, Roman enjoys being the detective who figures out why—and how to make them stronger. Stefan Kraft & Philipp Bergsmann (RedHat) ***Multi-factor authentication for Workload Identities w/ SPIFFE & SPIRE*** Authentication only with username & password is simply not state of the art, some (EU) regulations even explicity asks for using at minimum a second factor. But what about workload identities? How can they be multi-factorized? SPIFFE/SPIRE provides a proven, stable, hybrid-cloud capable solution for workloads to get authenticated w/o the hassle of managing secrets. In this talk, we will explain the architecture, discuss use-cases and show a live demo. Bios: Stephan has joined Red Hat 2019 as a Business Development Professional in Austria. He started his professional career as a Software Developer and later moved into Technical Sales, Solution Sales and Management. He was working for several companies in and around IT, particularly IBM and SWIFT. After a personal time-out, he has spent 3 years at universities as a program director of a Master and MBA program around Digital Transformation. This has lead him smoothly to Red Hat where he enjoys engaging with customers and partners around technical and cultural transformations. Philipp is part of the EMEA OpenShift Black Belt team at Red Hat, focusing on the managed cloud offerings. He has worked in the IT industry for about 20 years in various roles, from development to cloud infrastructure consulting. Over the last few years, Philipp has worked extensively on Kubernetes-related topics, planning and implementing Kubernetes platforms with various local and international companies.

Join us for another session of our study group as we dive into the fascinating world of Large Language Models (LLMs) using the book **Build a Large Language Model from Scratch** from Manning. In this session, we will finish **Chapter 7: Fine-tuning to follow instructions**. In the last session, we talked about how to prepare the dataset for instruction fine-tuning and in this session we will perform the fine-tuning and evaluate the model afterwards. This isn't just a lecture! Come ready to ask questions, share insights, and code along. Whether you're a beginner or have some experience, this is the perfect opportunity to build a strong foundation together. If you plan to work with the code on your own laptop during the session, try and set-up the environment ahead of time (https://github.com/rasbt/LLMs-from-scratch/tree/main/setup). We will be meeting at the North County Governmental Center this time that is across from the Reston public library.
