**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. Du kannst direkt loslegen und dich ganz auf das kreative Arbeiten konzentrieren. Wenn du zusätzliche Farben oder Charms verwenden möchtest, kannst du diese flexibel ergänzen. 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.

Accessibility often feels overwhelming with all its guidelines, standards and edge cases. But in practice, meaningful improvements don’t require perfection. They require empathy and a sincere motivation to create a truly usable experience for all. In this talk, we share real learnings from UX and UI projects: what actually made a difference, where teams struggled, and how small, deliberate changes created a much more inclusive experience. You’ll walk away with a practical mindset and actionable ideas to start improving accessibility in your own projects — without waiting for the “perfect” solution. By Maria Timonen & Silio Keiser from Bitforge

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
