**Walk description (It’s the same hike that was planned for May 15th but got canceled due to the weather.):** This hike is still a T3 but it starts to be difficult because of the elevation gain (2000m). We start our hike at 9:00 am at Erstfeld station and make our way to the Hoch Geisberg. There may still be a bit of snow on the trail, but not much. https://whiterisk.ch/de/conditions/snow-maps/snow_depth According to the time we have left, we could take a shorter route to Altdorf — for example, by following the cable car down to Attinghausen. https://www.komoot.com/de-de/tour/2940708678?share_token=aAvsxogJd0MklM8gNjkB6fVOGRAKuOCavOmMMVYrlRlg1TPp7y&ref=wtd&t_s=referral&t_cid=route_share&t_ref_username=4403209765193 Possibility to go swimming in the waldnachter seeli or in the Reuss **How to go with the train (from Zurich and I will meet you on the way):** https://www.sbb.ch/de?stops=Z%C3%BCrich+HB_I8503000\~Erstfeld_I8505114&day=2026-05-25&time=07_00&moment=dep&trip=1 **dedicated whatapp group** https://chat.whatsapp.com/J0JPyXgjnGd7j30ZCZTmiU **Registration:** To sign up, please select "Yes" in the WhatsApp community survey for this activity: [🌄 Switzerland Discovery Crew (Preferred Ages 18-35)🌄 | WhatsApp-Kanal](https://www.whatsapp.com/channel/0029VaoercY1XquRrJm58k3V) If the event will happen in more than 30 days, I haven't added the survey in the channel yet. (Because message in a WhatsApp channel can be read by a new member only 30 days before he joins. But you can already enter the corresponding WhatsApp group) If you are concerned about privacy, only the admin of a WhatsApp channel can see who has voted in a poll (unlike a WhatsApp group). Please sign up only when you are certain! You can also register through Meetup, as it helps build momentum; however, I rely only on the number of people who signed up through the WhatsApp survey.

Der Decoden Workshop bietet dir die Möglichkeit, in eine verspielte und kreative Welt einzutauchen und deine eigenen Decoden-Charms und Accessoires zu gestalten. Decoden ist eine dekorative Technik, bei der mit einer cremigen Leimmasse, Farben und süßen Charms gearbeitet wird. Dabei entstehen einzigartige Designs, die sowohl kreativ als auch individuell sind. Dieser Workshop eignet sich perfekt für alle, die etwas Neues ausprobieren und mit wenig Aufwand tolle Ergebnisse erzielen möchten. Im Decoden Workshop kannst du verschiedene Gegenstände nach deinem eigenen Stil gestalten. Zur Auswahl Bilderrahmen Etuis Handspiegel & Tischspiegel Schmuckkästchen Haarklammer Du entscheidest selbst, welches Objekt du dekorieren möchtest und wie verspielt, farbenfroh oder minimalistisch dein Design ausfallen soll. Jedes Werk ist ein Unikat und spiegelt deine persönliche Kreativität wider. Pro Gegenstand benötigst du etwa 15 bis 30 Minuten, je nach Detailgrad und Design. Dadurch eignet sich der Workshop sowohl für kurze kreative Pausen als auch für längere Bastelzeiten. Du kannst auch mehrere Objekte nacheinander gestalten, wenn du Lust hast, verschiedene Designs auszuprobieren. Der Preis startet ab 29 CHF pro Gegenstand. Im Preis enthalten sind eine Farbe und 20 Charms. Alle Materialien stehen für dich bereit, sodass du nichts mitbringen musst.

Auch Anfänger\*innen sind herzlich willkommen. Du brauchst keinerlei Vorkenntnisse, um am Decoden Workshop teilzunehmen. Ich erkläre dir Schritt für Schritt, wie die Technik funktioniert, wie du den Leim richtig aufträgst und wie du deine Charms platzierst, damit dein Design harmonisch wirkt. Während des gesamten Workshops stehe ich dir mit Tipps und Unterstützung zur Seite.

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.

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! Location https://zurich.impacthub.ch/space/bogen_d/ Viaduktstrasse 93, 8005 Zürich, Switzerland Visit our website https://webzurich.ch/ for more information about the Web Zurich community.

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** TBD
