Charis Arnold will present «Klingende Werte», a project exploring data sonification in the context of multiple sclerosis. Charis will share the project's development, from initial concept to discovering data sonification through human data. The presentation covers the tools used, including TwoTone, Cavalry, and Google Sheets, and discusses future directions for making this work accessible to people living with chronic illnesses, as well as its potential applications in research. **Speaker:** [Charis Arnold](https://www.charisarnold.ch/) is a multi-disciplinary designer working in data visualization, editorial design, brand design, and illustration based in Zürich. **Agenda**: 17:00 Doors open 17:00–17:30 Drinks & chats 17:30–18:30 Presentation 18:30–19:00 Drinks & chats 19:00 Goodbye! **Format**: This session will be a presentation followed by a plenary conversation for questions and answers with our speakers. **Language**: Please note, this presentation will be held in German. **Streaming:** If you can’t be with us in person, you can join the livestream at 17:30 on Zoom. **You don’t need to register on Meetup to join virtually.** Link: https://us02web.zoom.us/j/85774605309 Interactive Things will provide drinks and snacks and moderate the presentation.

Join us, metalheads of Zurich and its surrounding areas, in our regular Wednesday meetup for some afterwork drinks, chaotic socializing and listening to heavy music! **Where?** The meetup will be held at ***[Ebrietas Bar](https://ebrietas.ch/)*** \- a metal & rock bar located in Zurich's oldtown and boasting a selection of whiskeys\, rum & spirits\, in addition to countless shot creations and over 21 different types of beer\. **When?** The gathering will officially begin at \~7:00pm and normally goes until midnight. However, members often arrive slightly earlier and might stay until the following day! You are welcome to join at any point and leave whenever you please. **Attendance:** Attendance can vary, but the number of people at the gatherings is normally somewhere between 20 and 40 metalheads! The group is comprised by a balanced mixture of longstanding members, semi-regulars and curious visitors. **Chats:** Get invited to our chat-groups by introducing yourself at one of the meetups! We currently offer an "official" chat for announcements, updates on events & organizing concerts, a "fun" chat for casual discussions & informal events, and a meme chat for silly discussions and somewhat thematic memes. You can join neither, some or all! **FAQ:** "*How can I find the group?*" We normally reserve one of the larger tables at the bar and decorate it with a large black flag. If you still have trouble finding the group, feel free to approach the bartenders and they will point you our way. "What happens if I arrive late?" Nothing really. We will give you a warm welcome and introduce you to the others, no matter at which time you arrive 🙂 "*What can I expect from these meetups?*" Think of a common "after-work meet & drink", but in a themed bar, with lots of band-shirts and metal music playing in the background. Guests normally show up, grab a drink and join a clique for a conversation. "*Do I need to be a hardcore metal fan for this meetup?*" Not really. The theme of this meetup is indeed metal music and most members do have a liking for it, but plenty others are more casual listeners or more into rock/punk/goth. We welcome all!

Web Zurich presents inspiring talks all about the web. Join us for the Mai 2026 meetup! We will have three talks as well as chit-chat and drinks. Whatapp: [https://chat.whatsapp.com/FxOfVTK9nf431xHtVl3eGK](https://chat.whatsapp.com/FxOfVTK9nf431xHtVl3eGK) Website: [https://webzurich.ch](https://webzurich.ch) 18:30 \~ 19:00 Arrival time with drinks, chat 19:00 \~ 19:10 Welcome and introduction 19:10 \~ 19:30 *Alex Suzuki* **Monetizing JavaScript: Building Profitable Products as a Solo Developer** Lessons learned from building and launching a commercial JavaScript library as a solo developer. 19:30 \~ 19:50 *Hugo Sousa* **Ten times tea** I'm building a programming language. When I got to the frontend, I ran into a problem: React's mental model is elegant, but the mental model is at odds with the code. Hooks, effects, and render passes create a runtime that bears little resemblance to the code we write. The Elm programming language works differently and its architecture (TEA = The Elm Architecture) has been adopted by other tools over the years. So I copied it as well. My language embeds TEA at the language level, not as a library. This unlocks time-travel debugging, reproducible application state and serializable bug reports that include the entire program state. This talk covers the quick introduction of my language, TEA, why TEA is the right fit and what becomes possible when the architecture is baked into the language itself. 19:50 \~ 20:10 *Marco Gähler* **Software testing** Many old software projects don't have any tests - if the code works, why should you bother with tests? Well, you really should bother, because code changes all the time. During development, you keep adding new features which at times requires large scale modifications of the code that will inevitably alter existing functionality. And in existing projects, one still has to make updates once in a while, for example for security patches. These things will always break existing functionality and tests are the only remedy against this issue. In this talk, we will look at the basic idea of tests, how to implement them, what issues to look out for and how you can test pretty much any piece of code if your code base is well structured. 20:10 onward More drinks & chat We look forward to see you there!

The OWASP community is getting together for another meetup in May 2026! Join us for some security talks 🔐, good company 🤝, and a little aperitif 🍕. **Program:** **16:00** - **Doors open**: Grab a drink, meet old and new friends from the OWASP Switzerland community **16:30** - **Hello from OWASP Switzerland** **16:40 - Talk: AI-Driven Development Lifecycle (AI-DLC) (Markus Rollwagen, Senior Solutions Architect, AWS)** **17:25** **-** **(10min break)** **17:35 - Talk: Using HoneyPots to protect critical Infrastructure (Giulio Grazzi, Head IT Security, SRF)** **18:35** - **(10min break)** **18:45 - Talk: We Tried to Detect Prompt Injection in Coding Agents. Here's What Broke (Paulo Martins, Principal Security Engineer, GitLab)** **19:30 - Networking & Pizza 🍕 & Aperitif**🍷- Grab a bite and chat with old and new friends **Talks Details:** **AI-Driven Development Lifecycle (AI-DLC) (Markus):** Software development is undergoing a fundamental shift. AWS’s AI-Driven Development Lifecycle (AI-DLC) positions AI not as a mere assistant, but as a central collaborator across the entire SDLC — from requirements to deployment. In this session, we’ll explore how AI-DLC’s three phases — Inception, Construction, and Operations — redefine team workflows, and what this means for security: how AI enforces organization-specific security standards consistently, maintains human oversight at critical decision points, and ensures traceability from requirements to deployment. We’ll discuss the security opportunities and risks this methodology introduces, and how teams can adopt AI-DLC while keeping security a first-class citizen in every “bolt.” **Using HoneyPots to protect critical Infrastructure (Giulio):** How do you protect your critical infrastructure in the days of agentic ai and very limited options on your hosts? You need to get creative and use stone age tech. I’ll give you some insights, from our journey and pitfalls you might be facing (and should be avoided :)) **We Tried to Detect Prompt Injection in Coding Agents. Here's What Broke (Paulo):** As a community, we are delegating a significant part of our development workflow to agents, and as the use cases grow, the risk of prompt injection keeps increasing - to the point that it made it to the top of the OWASP LLM Top 10. In this talk, I'll explore the concept of "detect and prevent prompt injection" and why it is particularly hard to do for coding agents. **Speaker Details:** **Markus Rollwagen** Senior Solutions Architect at AWS, based in Switzerland Markus enjoys deep dive technical discussions, while keeping an eye on the big picture and the customer goals. With a software engineering background, he embraces infrastructure as code and is passionate about all things security. **Giulio Grazzi** Head IT Security, SRF From bike messaging to networking to infosec - always maximize never max out. Currently at Schweizer Radio und Fernsehen dealing with all Infosec topics, background in networking, embedded devices and mobile security. **Paulo Martin** Principal Security Engineer, GitLab since 2021 Now focused on AI security: prompt injection, sandboxing, and keeping agentic workflows from doing things they shouldn't.

🌿 Fühle, Vertraue, lass dich fallen Es gibt diese Momente, in denen man merkt: man hat den ganzen Tag den Boden nicht gespürt. Nicht den Kies, nicht das Gras, nicht das Wasser. Den Körper auch nicht so richtig. Dieser Nachmittag ist genau das Gegenteil. Wir gehen barfuss eine Strecke entlang, auf der sich der Boden ständig verändert – Kies, Wiese, Wasser, Holz. Eine Kneipp-Anlage als roter Faden. Zwischendurch halten wir an und arbeiten miteinander: jemandem das Gewicht überlassen, sich tragen lassen, mit geschlossenen Augen geführt werden. Sachen, die im Kopf einfach klingen und im Körper plötzlich echt sind. Danach setzen wir uns in den Kreis. Eine Runde, ca. eine Stunde, jede:r teilt, was drin war. Und dann ist der Tag offen. Wer baden will, badet. Wer weiter erzählen will, erzählt weiter. Wer Musik machen will, macht Musik. Picknick auf der Wiese, jeder bringt was mit. Du musst nichts können. Du entscheidest, wie weit du dich öffnest. Wenn dir eine Übung zu viel ist, machst du sie nicht. Kosten: Kostenlos / Spende Gruppe: max 15 Mitbringen: Picknick zum Teilen, Badesachen, Tuch, Decke zum Sitzen, Wasser. Wenn du magst: ein Instrument. Bis Bald 🫶 \-\-\- 🌿 Feel, trust, let go There are these moments where you realise: I haven't felt the ground all day. Not gravel, not grass, not water. Not really my body either. This afternoon is the opposite of that. We walk barefoot along a path where the ground keeps changing – gravel, grass, water, wood. A Kneipp trail as the thread running through it. In between, we stop and work with each other: handing your weight to someone, letting yourself be carried, being guided with closed eyes. Things that sound simple in the head and suddenly become real in the body. Then we sit in a circle. One round, about an hour, each person shares what came up. And then the day stays open. Whoever wants to swim, swims. Whoever wants to keep talking, keeps talking. Whoever wants to make music, makes music. Picnic on the meadow, everyone brings something. You don't need to know anything. You decide how far you open up. If something feels too much, you skip it. Cost: Free / Donation Group: max 15 Bring: picnic to share, swimwear, towel, blanket to sit on, water. If you like: an instrument. See you soon🫶

**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** Like it or not, AI agents are now capable of turning a quickly written paragraph of requirements into a pull request that is ready to be integrated into real-world production applications and it's now our responsibility to make sure AI doesn't go rogue and take down prod - or corrupt our data by misunderstanding the requirements or our existing schemas. In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** https://youtube.com/live/BltmWMH1zG0?feature=share
