Reactive Programming

Dies ist ein informelles Treffen für Lernende, die ihre ersten Schritte in der Programmierung machen oder ihre Grundkenntnisse vertiefen möchten. *** This is an informal meetup, for learners that want to do their first steps in programming or want to consolidate their skills. We spend one hour and a half working on tutorials, exercises or projects. If you need help to get started, we will help you finding a good way for learning. You should be prepared to spend your time "doing things": just hanging around and listening might get boring, if all other people are learning on their side. There are experienced people are around and you can ask questions as soon as their arise or bring with you questions you have had during the week. During the last half an hour, we do a (simple) exercise together. We speak German, English, and a few other languages. Currently, how main programming languages are: * Python * Javascript * Java * Flutter * C++ * C * C# * PHP But you're free to learn any programming language during our Co-Learning! If you want to learn more about our Co-Learning, please have a look at our website (no frequent updates...): https://opentechschool-zurich.github.io/ If you're starting with Python, we can suggest: * Learning Python the hard way (https://learnpythonthehardway.org/python3/) (for Python 3). * The Solo Learn Python 3 Tutorial (https://www.sololearn.com/Course/Python/). * A big list of Python tutorials: https://docs.python-guide.org/intro/learning/ For Node.js: * Nodeschool: https://nodeschool.io/ For C++ * https://de.wikibooks.org/wiki/C%2B%2B-Programmierung * https://www.sololearn.com/Course/CPlusPlus/

**Cloud Native Night Munich** AI agents are rapidly evolving from simple assistants into autonomous systems capable of reasoning, maintaining context, and interacting with complex environments. In this meetup, we’ll explore two practical applications of modern agentic AI in software engineering. The first talk dives into building stateful AI agents that work with real-time data, covering the architectural patterns and challenges behind creating responsive, context-aware systems. The second talk showcases how agentic AI can be applied to understanding and analysing complex legacy applications — helping uncover program flows, dependencies, and hidden system knowledge that would otherwise take countless hours to explore manually. Whether you’re building AI-powered applications, modernising enterprise systems, or simply curious about the future of intelligent software, this meetup offers hands-on insights into how AI agents are transforming the way we interact with technology THIS MEETUP WILL BE HYBRID. **\|** Zoom Link will be available shortly before the meetup \*\*\* AGENDA \*\*\* * 6\.30 PM \| Doors open\. Grab some snacks & drinks\. * 7\.00 PM \| Welcome & Intro – **Start of hybrid meetup** * 7\.15 PM \| **Building Stateful AI Agents with Real-Time Data**, Gregor Bauer (VP Customer Engineering at CrateDB) * \~8:15 PM \| **Hosty - The next level with Agentic AI,** Martin Binder (Lead IT Consultant at QAware) * afterwards: More snacks & drinks, and a lot of time for networking with all attendees and speakers. \*\*\* ABSTRACTS \*\*\* **Building Stateful AI Agents with Real-Time Data**, Gregor Bauer (VP Customer Engineering at CrateDB) Most AI demos are stateless. Real systems are not. Modern AI applications increasingly depend on continuously changing operational data: events, metrics, logs, transactions, sensor streams, and user activity. This creates a new architectural challenge: how do we build AI agents that can reason over live data while remaining scalable and observable ? This talk explores the architecture of stateful AI systems and agentic applications. We will cover: * streaming-first AI architectures * real-time context enrichment * combining vector search with structured queries * memory layers for AI agents * latency and scalability considerations * operational lessons from large-scale data platforms The session provides practical guidance for engineers designing production-ready AI platforms. **Hosty - The next level with Agentic AI,** Martin Binder (Lead IT Consultant at QAware) To migrate legacy systems, you need to understand these IT dinosaurs, at least partially. So code analysis up to a certain level is unavoidable. What used to take months, sometimes years without LLMs is now doable in a few days with Gemini and friends. And yet: you still have to drive the analysis yourself, stitch the LLM's partial results into a coherent picture and fight the context window. With old source files thousands of lines long, that part really hurt. Agentic AIs like Claude Code are not just another AI feature. They change how you approach unfamiliar systems — fast, and without the headaches that LLM chat workflows used to come with. Teaser: an analysis that took us a few days under "yay!" cheers is now done in minutes. \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* Please comply with our [Code of Conduct](https://www.greenmanifesto.de/en/code-of-conduct).

In dieser Session dreht sich alles um die **Optimierung agentischer KI** unter dem Gesichtspunkt der Ökologie. Mit der zunehmenden Verbreitung von KI in Unternehmen entwickeln sich Token-Verbrauch, Inferenzkosten, Orchestrierungsaufwand und Kontextmanagement zu entscheidenden betrieblichen Herausforderungen. Die nächste Phase der KI-Entwicklung wird nicht nur von der Intelligenz der Modelle abhängen, sondern auch davon, wie effizient diese Intelligenz orchestriert, gesteuert und skaliert werden kann. Lean Agentic AI stellt einen architektonischen Ansatz vor, der Lean-Engineering-Prinzipien auf agentische Systeme anwendet – wodurch unnötiger Token-Verbrauch reduziert, redundantes Schlussfolgern minimiert und die Recheneffizienz durch modulare Agenten, selektive Orchestrierung, adaptives Gedächtnis und abrufgesteuerte Intelligenz optimiert wird. Somit verringert sich automatisch auch die Umweltauswirkung von KI. Zu Gast haben wir Navveen Balani, Executive Director bei der Green Software Foundation und ausgewiesener Experte in der Anwendung und Optimierung von KI. Er zeigt und, wie tokenbewusste Architekturen Skalierbarkeit, Latenz, Governance und ROI verbessern können und es uns gleichzeitig ermöglichen, produktionsreife KI-Ökosysteme aufzubauen, die effizient, kontrollierbar und in großem Maßstab nachhaltig sind. Die Diskussion basiert auf den Konzepten aus dem Buch des Autors, „Lean Agentic AI“.

**Live stream and very limited on-site seats available.** **Please use the registration page to join:** **[REGISTRATION PAGE](https://content.software-leader.com/juval-talk-june-2026)** **Topic: Architect in the Age of AI** **In short:** AI code generation presents businesses with a critical challenge: how to benefit from AI code generation, while containing the cost of AI. By default, AI generates very complex code that is not reusable, and it lacks design integrity. The cost of ownership of this code could exceed by multiples the cost of human-generated code. Instead of gains, developers experience strains trying to understand what the AI has generated. Companies now transition from AI euphoria to AI spaghetti. Throttling back token spending does not address the underlying complexity. In this dense session Juval explains what AI is doing wrong, and what businesses are doing wrong trying to leverage AI. Juval will then discuss the crucial role of the architect in unleashing the productivity gains of AI, using the best practices of software engineering. You will see how to future-proof your career, how to avoid being a casualty of AI, and how to be indispensable to your business, saving it from out of-control AI spending and complexity. Juval Löwy is the founder of IDesign and a master software architect. Over the past 20 years, Juval has led the industry with some of his ideas such as microservices – serving as the foundation of software design and development. Juval has mentored thousands of architects across the globe, sharing his insights, techniques, and breakthroughs, and has helped hundreds of companies meet their commitments. Juval participated in the Microsoft internal strategic design reviews and is a frequent speaker at major international software development conferences.

*«The creative and UX industry is changing fast. Roles are shifting, tools are evolving, expectations are rising, and many people are asking what their skills will be worth in the future.»* **This evening is not a classic Last Thursday Talk.** UX Schweiz and Syndicom invite the community to **a workshop and open exchange** for people working in UX, design, research, strategy, communication and related creative fields. The focus is especially on people at the beginning of their careers, people in transition, and everyone currently asking: **What does the future of our work actually look like?** We want to create a space for hopes, concerns, changing roles, useful skills, new tools, AI, career paths and possible forms of support within the community. Uncertainty is allowed, but we do not want to stay stuck in fear. The evening starts with a short input by **[Pascal Geronimi](https://www.linkedin.com/in/pascal-geronimi-5112b324/).** After that, we will work in small groups: collecting thoughts, clustering topics, discussing what matters most, and sharing key insights. Together, we want to explore: * What currently gives us hope? * What feels uncertain or worrying? * How are roles, tools and expectations changing? * Which skills and mindsets might become more important? * What kind of support could UX Schweiz, Syndicom or the wider community offer? **This is an experimental format.** Because this is a workshop-style event, **places are limited**. Please only register if you are quite sure you can attend. If your plans change, please cancel your RSVP so someone else can join. **Format** * Short intro input * Small-group exchange * Shared takeaways in the plenum * Optional informal drinks afterwards nearby **A small question before you come** You do not need to prepare anything. But take a moment to think about this: ***When you think about the future of your work: what gives you hope, and what makes you unsure?*** **Practical information** • The event will be held in English. • The number of participants is limited. • Please arrive a few minutes early so we can start on time.

Dear Microsoft Swiss PSUG, We have planned another exciting event. **Place & Language:** Place: Isolutions AG, The Circle 38, 8058 Zürich (Hybrid with Teams) Language: EN **Session 1: PowerShell Notebooks in Practice: Real‑World Use Cases** Description: PowerShell Notebooks can significantly enhance how we build and operate tools. This session showcases practical, real‑world scenarios—including onboarding and offboarding workflows, pipeline integration, diagnostic data collection, and development against both on‑prem and cloud services. With plenty of demos, you’ll see how notebooks can improve productivity and clarity across the entire lifecycle. Speaker: [MVP David Sass](https://www.linkedin.com/in/sassdawe/ "https://www.linkedin.com/in/sassdawe/") **Session 2: Updating isn’t the hard part — Knowing What changed Is** Description: PowerShell modules evolve constantly — features change, bugs are fixed, and behavior shifts. While updating a module is easy, understanding the impact of updates is not. Outdated modules risk lost functionality, while rushed updates can introduce subtle breaking changes. In this demo-focused session, we explore a practical approach to tracking meaningful module changes without notification overload. Using the PackageUpdateInfo module, we show how to detect and report relevant differences between versions. Speaker: [David Bellstedt](https://www.linkedin.com/in/andreasbellstedt/ "https://www.linkedin.com/in/andreasbellstedt/") **Agenda:** 17:00 Welcome 17:30 Session 1 18:15 Session 2 19:00 Networking and Beer 20:00 End of Event

🚀 **Vom Code zum Kosmos: Programmieren lernen mit Python** Programmieren wirkt oft kompliziert. Doch die Grundlagen lassen sich einfacher verstehen, wenn man die Auswirkungen des eigenen Codes direkt sehen kann. In diesem Workshop erhalten Sie einen verständlichen Einstieg in die Programmiersprache Python. Gemeinsam erkunden wir grundlegende Konzepte wie Variablen, Schleifen und Funktionen und lernen, wie Computer Programme ausführen. Anstatt nur Text auf dem Bildschirm zu betrachten, verwenden wir einfache Animationen und Weltraumvideos als Lernwerkzeug. So werden Änderungen am Code sofort sichtbar und die wichtigsten Programmierkonzepte lassen sich intuitiv nachvollziehen. * Was macht ein Computer eigentlich mit einem Programm? * Was sind Variablen, Schleifen und Funktionen? * Wie verändert eine kleine Änderung im Code das Ergebnis? * Wie entstehen aus Programmcode einfache Animationen? Vorkenntnisse sind nicht erforderlich. Der Workshop richtet sich an alle, die einen ersten Einblick in die Welt des Programmierens erhalten möchten. Am Ende des Workshops werden die Teilnehmenden die Grundstruktur einfacher Python-Programme verstehen, Code lesen und anpassen können und erlebt haben, wie Programmcode sichtbare Ergebnisse erzeugt. Bitte bringen Sie Ihren eigenen Laptop mit und installieren Sie Python vor dem Workshop. Begleiten Sie uns zu einem Abend voller Entdeckungen und erster Schritte in die Welt des Programmierens. In Volketswil heisst es: Ready for launch. 🎟️ Ab 16 Jahren: CHF 25 bei Voranmeldung via [info@volkibrains.ch](mailto:info@volkibrains.ch), CHF 30 an der Abendkasse Bis 15 Jahre: kostenlos 📍 Ort: Stationsstrasse 25a, 8604 Volketswil 📅 Datum: Donnerstag, 25. Juni 2026, 18:00–20:00 Uhr (Türöffnung 17:45 Uhr)

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD

It’s time to take control of your mental health. How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself. Here is the secret of being positive and free: Thinking positively is not enough. You also have to get rid of the negative thinking. Your mind is like a garden. You can plant many beautiful flowers in it, but if you don't get rid of the weeds when you plant your flowers, the weeds will soon take over the whole garden. A positive thought is like a flower in your mental garden, and a negative thought is like a weed. You cannot expect to have a positive mindset if you continue to have negative thoughts dwelling and growing there. So, how do you get rid of the negative thoughts? That's what this Meetup is all about. Attend this local meeting and find out! The Meetup event will be led by a consultant who had helped many people live happier in life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Dianetics & Scientology life improvement center.

Most people still use AI like a search box: type one question, get one answer, repeat. But the next step is AI agents: systems that can take a goal, break it into steps, use tools, remember context, and produce useful work for a human to review. In this beginner-friendly session, we’ll demystify what AI agents actually are — without hype or jargon. We’ll walk through practical examples of how agents can help with research, planning, writing, coding, operations, and personal productivity. We’ll cover: * What makes an AI “agent” instead of just a chatbot * How agents break tasks into steps * Where agents are genuinely useful today * Where they fail, hallucinate, or need human review * How to design simple AI workflows for your own work * A live demo of an AI agent-style workflow from start to finish No coding experience required. This is for anyone who wants to understand where AI tools are going and how to use them more effectively right now. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
