Reactive Programming

Software delivery is changing faster than most organizations can keep up with. Teams are shipping more. Expectations are rising. New capabilities are entering the development workflow at speed. But behind the momentum, many organizations are asking the same questions: * What does this actually change for our teams? * How do we adopt this without losing control? * And what do we need to have in place to make this work? Because one thing is becoming clear: *The gap between teams that adapt and those that don’t, is growing fast.* This event gives you a clear, practical view on what’s happening, what it means for your engineering organization, and what you should be doing next. **Real insights, real trade-offs, and real next steps.** Program and Registration: https://events.xebia.com/microsoft/ai-reshaping-software-delivery-zurich-june-2

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/

Shooting only in Auto or Program mode is a thing of the past. We will learn when it makes sense to use Manual (M), Shutter Priority (TV), or Aperture Priority (AV) modes to create artistic compositions under a wide variety of conditions. This workshop is designed for beginners as well as photographers who want to dive deeper into their camera settings, lenses, and the many features their gear has to offer. **Part 1: Getting Started (2h)** * **Full Control:** Mastering Manual (M) mode. * **The Essentials:** Understanding Aperture, Shutter Speed, and ISO, and how they shape your image. * **Semi-Auto Modes:** When and why to use AV or TV modes. * **Focus:** An insight into various autofocus options. **Part 2: Lenses & Perspective (2h)** Unlike prime lenses, telephoto lenses offer more flexibility without having to move—but they also come with specific challenges. We will explore the pros and cons of different lenses and learn which glass is best suited for which purpose. **Part 3: Practical Application (2h)** Putting theory into practice outdoors, followed by a final Q&A session. **Course Hours:** The course runs from 10:00 AM to 5:00 PM. **Registration:** Please register by **May 24, 2026**, via email at admin@michaelcalabro.com. The course requires a minimum number of participants to take place. Confirmation will be sent as soon as the minimum number is reached. **Participants:** Min. 4 / Max. 8 www.michaelcalabro.com

Two very different, complementary topics for our June evening. One on the small, everyday habits that make teams actually collaborate. The other on how a platform and a cultural movement transformed IT in the public sector. Here's what's planned for the evening: 17:30 - 18:00 - Arrival and first drinks 18:00 - 18:45 - Micro Habits for better Teamwork by Dr. Denniz Dönmez 18:45 - 19:30 - From DevOps to Digital Sovereignty: How a Movement Became a Platform by Syrian Hadad 19:30 - 20:30 - Networking, Open Space & More drinks\* **Micro Habits for better Teamwork** Great teamwork is like solving a puzzle, and not like playing poker, it's not about playing against each other, but rather achieving real collaboration. Micro Habits are psychological hacks that create big results in teams. Micro Habits for Better Teamwork span seven behavioral domains, such as taking responsibility, creating psychological safety, and testing our assumptions. Each provides concrete, small, actionable behaviors that lead to major improvements in collaboration. This talk presents practical, everyday tools based on real-world experience that can be applied immediately to make teamwork easier and more effective, without lengthy coaching programs or complex team-development processes. With Micro Habits, teams unlock their full potential step by step. **Dr. Denniz Dönmez** Scientific agilist and co-creator of Micro Habits for better Teamwork. 15 years experience leading teams and consulting market leaders with a background and PhD in agile methods. **From DevOps to Digital Sovereignty: How a Movement Became a Platform** IT in the public sector is anything but simple: long-established landscapes, strict regulatory requirements, complex processes, and often more than 500 business applications that must be operated reliably. For a long time, this meant ordering individual servers, databases, DNS entries, firewall rules, and storage, then assembling everything manually. Every application was unique. Pets instead of cattle. This talk tells the story of how the DevOps idea took hold in exactly this environment — first as a cultural movement, and later as a concrete operating and architectural model. Step by step, individual infrastructure evolved into a platform, manual work into automation, and isolated solutions into standardization. The result: the Aargau Cloud Platform and a dedicated platform engineering team. In an environment shaped by legacy systems, federal structures, and long lifecycle expectations, platform thinking becomes the foundation for digital sovereignty: maintaining control, reducing dependencies, and still staying innovative — without simply handing everything over to others. **Syrian Hadad** Syrian Hadad is a CTO and long-standing technology and platform leader in the public sector. Among other achievements, he built the Aargau Cloud Platform and helped establish DevOps, cloud, and architecture topics strategically within the organization. Together with the IT organization of the Canton of Aargau, he won the 2023 Digital Economy Award (Digital Excellence) for the consistent transformation toward platforms, cloud-native technologies, and modern governance.

Dear Friends of Haskell, The schedule for ZuriHac 2026 is now online on [zurihac.info](https://zurihac.info/)! This year’s keynote speakers include Simon Peyton Jones (one of the creators of Haskell), Evan Czaplicki (the creator of the Elm programming language), and GarrickChin (developer of the “Defect Process” 2D hack n' slash game on Steam). We also have a track on Category Theory, given by Jencel Panic (author of “Category Theory Illustrated”), as well as a track on rolling your own dependent types given by Andres Löh and Andrea Vezzosi. The Beginners’ Track this year will be given by Michael Sperber (CEO of Active Group and author of “Schreib dein Program”), who will also talk about teaching programming. Our website [zurihac.info](https://zurihac.info/) contains further information on keynotes and tracks and will be updated regularly. In case you have not registered yet, please do so ASAP via the link [https://zureg.zfoh.ch/register](https://zureg.zfoh.ch/register) (also on our website). Although registration is free for participants, it allows us to plan appropriately for the event: Jane Street and IOG are providing food in the evening, and we want to minimize waste. For the uninitiated: ZuriHac 2026 will take place Saturday 6 June – Monday 8 June 2026 as a physical event at the Rapperswil-Jona campus of the OST Eastern Switzerland University of Applied Sciences. ZuriHac is the biggest Haskell community event in the world: a completely free, three-day grassroots coding festival co-organized by the Zürich Friends of Haskell and the OST Eastern Switzerland University of Applied Science. It is not your standard conference with papers and presentations, but features fantastic keynotes, hands-on tracks, hacking on many of your favourite projects, and of course lots of socializing! Organizing ZuriHac would not be possible without the support and help of: * CircuitHub * Digital Asset * IOG * Jane Street * OST * Tweag * Well-Typed In case you would like to support ZuriHac, as a company or as an individual, please get in touch with us, we would be grateful: [https://zfoh.ch/#donations](https://zfoh.ch/#donations) We hope to see you there!

Dear members of HaskellerZ I am pleased to invite you to the following guest lecture from the creator of the Elm programming language, Evan Czaplicki. Please note that it is at the OST campus in Rapperswil. Title: **Making Web Apps can be Fun!** **How to use Functional Languages at Work.** Speaker: **Evan Czaplicki** Date & Time: 03.06.2026 17h15-19h00 Place: **OST Campus at Rapperswil \| Lecture Hall 5\.002** Abstract: Typed functional languages have had success in some surprising places. From high frequency trading at Jane Street, teaching physics and engineering at Brilliant, and plenty of businesses in between. We will go through some case studies to build an intuition for why a functional language is likely (or unlikely) to succeed in a given business scenario. From there we will dive into Elm ([https://elm-lang.org](https://elm-lang.org/)), a simple functional language that runs in browsers. If we have time, we will build a little website together. You should come away from this talk with (1) the core knowledge needed to build your own functional front-end and (2) an intuition for when it is a good business idea to do so. You do not need to know functional programming to enjoy this talk. Speaker Bio: Evan is the author of the Elm ([https://elm-lang.org](https://elm-lang.org/) <[https://elm-lang.org/](https://elm-lang.org/)\>\) and Acadia \([https://acadia.engineering](https://acadia.engineering/) <[https://acadia.engineering/](https://acadia.engineering/)\>\) programming languages\. He has been developing compilers and servers in Haskell for nearly 15 years\, and has significant expertise in using low\-level techniques to get the best possible performance out of Haskell programs\. I look forward to seeing you there!

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.

## 🤝 Host Information A co-hosted event by ProductTank Columbus & Women in Product Columbus 💡 About the Workshop AI adoption is stalling across organizations — not because of a lack of motivation or tools, but because it's fundamentally a behavior design challenge. This hands-on workshop applies proven Behavior Design models and methods to help you move from a vague organizational wish to boost AI adoption to 3-5 concrete, testable interventions you can act on starting tomorrow. Whether you're a product manager, on a product team, or just someone trying to get AI to actually stick at work, you'll leave with a clear picture of what's worth focusing on, what to ignore, and how to drive real, sustained adoption — no guesswork required. 🛠️ What to Bring Laptop: Fully charged and ready to go. AI Assistant: Have your favorite AI assistant pulled up. (Dom will be using Claude, but feel free to use whichever assistant you prefer!) 🍕 Logistics & Perks Food & Drink: Pizza and drinks provided! Parking: Plenty of free spaces available on-site. ###
