This talk will discuss a playbook security teams can apply today — covering the CSA "Mythos-Ready" framework, AWS Security Agent, agentic threat modeling, and the fundamentals that continue to work **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.

Come and get you **Comedy Brew**, your fix of English Stand-Up Comedy! We serve a fresh, locally sourced 'menu' of 10 comedians, as organic as your favorite farm-to-table meal, all geared up to make you laugh out loud. **Tickets at:** [https://bit.ly/iyfcb](https://bit.ly/iyfcb) Unleash your laughter at [ROBIN's coffee](https://maps.app.goo.gl/E1e3H9GRDDJaPK8z9), the coziest New York-style coffee bar in the heart of Zürich. **Dare to Make 'Em Laugh? 🎤😂** Ever fantasized about grabbing the mic and cracking some jokes yourself? Well, your dream could come true! Visit [our performer's page](https://inyourfacecomedy.ch/perform/) to find out how you can take the stage and spread laughs like a pro. **See You There! 🎤😂** Come down to ROBIN's, break some bread, share some laughs, and maybe even catch the comedy bug yourself! See you there every Thursday! Powered by IN YOUR FACE Comedy 🌟 [Check Us Out!](https://instragram.com/inyourfacecomedy/) **Tickets at:** [https://eventfrog.ch/comedybrew](https://eventfrog.ch/comedybrew) **Frequently Asked Questions** * ***Is the show really in English?*** Absolutely. Every set is performed in English by a mix of Swiss-based and international comics, so no Swiss-German skills required. * ***What’s a “Comedy Open Mic”?*** It’s the testing ground for jokes. Pros road-test fresh material and brave newcomers grab their first five minutes. Expect some gems, some flops—and the fun of seeing comedy born in real time. * ***Will it be funny?*** Most of the time, yes! An open mic is a roller-coaster: seasoned acts, new voices, and the occasional glorious train-wreck. It’s all part of the charm. * ***Can I perform too?*** Yes - you need to book a spot - find out more about how to do it here: [https://inyourfacecomedy.ch/perform/](https://inyourfacecomedy.ch/perform/). * ***Do I need to buy tickets in advance?*** Please do. We’re usually running around before the show and door sales slow things down. If you’re stuck, we’ll try, but no promises. Link to tickets as at [https://inyourfacecomedy.ch/comedybrew/](https://inyourfacecomedy.ch/comedybrew/) * ***How does seating work?*** First come, first served so grab a drink, snag a seat, and settle in. * ***Is food available at the bar?*** ROBIN’s serves drinks only. For a pre-show bite, try **Restaurant Johanniter** (classic Swiss) or **Holy Cow!** across the street for burgers. * ***Will the comedians pick on me?*** We chat with the crowd for laughs, not humiliation. Friendly banter only - you’re safe. * ***How long is the show?*** Doors open 7:30pm, show starts \~7:50pm with a 15 min break in the middle ending around 10pm. Enough time for the last trams home... * ***Age limit?*** All ages welcome of course 16+ recommended (adult themes, spicy language).

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.

The **"Connection Space"** is exactly the opposite of that; its a **fun** social environment outside family and work, a cultural exchange, where we **unite** and hangout with **new and old friends** as **one community**. . Thats it. . No to phones, laptops, zoom-calls, books No to a specific reason to get together (eg. only for specific hobbies, genders, age groups, languages etc) No to just talking to your friends Not a dating, not a party, not an expat-only meetup NO to division (political racial gender etc) . Yes to simple and real in-person connection with new and old friends YES TO FUN! We got many optional activities for you to try out Yes to feeling like home & come as you are Yes to unity, love and respect for one another Yes to eating, drinking and music Yes to everyone-is-welcome & always-free events YES to UNITY! Getting along with each other in spite of different opinions . Our events are **inspired** by the Greek village culture of "[Καφενείο](https://en.wikipedia.org/wiki/Kafenio)" (village coffeeshops) with photos [HERE](https://www.google.com/search?sca_esv=569660528&sxsrf=AM9HkKlXnclaLfgcockKtdr9qHdmD5jaGw:1696060562834&q=greek+%CE%BA%CE%B1%CF%86%CE%B5%CE%BD%CE%B5%CE%B9%CE%BF&tbm=isch&source=lnms&sa=X&ved=2ahUKEwi52fX67dGBAxXnlf0HHZNiBHUQ0pQJegQICRAB&biw=1460&bih=913&dpr=2). When myself Christos was a kid, my granddad took me to these "[Καφενείο](https://en.wikipedia.org/wiki/Kafenio)". Every neighbourhood had one, and people met, without an exaggeration, on a daily-basis. It was the community center of the village. People met new and old friends, played games, socialised, ate snacks, drank coffee and ouzo. It was a very friendly, welcoming and homey environment. Unfortunately this concept is rapidly dying in Greece. As a kid I had extremely good memories of these coffeeshops, and for this reason I am passionate to revive and recreate this environment and also add a modern twist. Hope you enjoy it! . * **WHAT is NOT Connection Space? NOT** a drinks or party event (responsible drinking only, no shots, no free drinks). **NOT** a dating event. **NOT** foreigners-only, but everyone is welcome * **What KIND of event is this?** Its a mix of **social** and **cultural event** that build **community**. We have many people from so many different cultures socialising, we promote culture with events with Art exhibitions and Live Music and we also revive the social culture of the Greek traditional village coffeeshop (Καφενείο - read more above). * **WHO?** Wir wollen gerne mehr **Schweizer/innen** dabei haben! Alle sind willkommen und die meisten können Deutsch sprechen. Not an expat event. **Everyone welcome**! * **Mindful Connection Games:** from [The School of Life](https://www.theschooloflife.com/shop/?_product_type=games-card-sets) available: Confessions Game, The Friendship Game, Connection Game, The Loser Game, Games for grown-ups and three sets of "100 questions" (Conversation Toolkit & Careers & Relationships) * **Fun Social Games:** bring your own **board/card games** or choose from: Cards against humanity, Exploding Kittens, Codenames, Debatable, Sotally Tober, Taboo, Mafia, Uno, Monopoly and more. . Looking forward to **fun quality Connections**! 🙂

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.

Whether you've never done improv before, or you've done it for so long you knew Del Close on a personal level, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup** for some fun and games! The idea behind improv is to create entire scenes from scratch based on a suggestion from the audience. This can be done in game form, like *Whose Line Is It Anyway*, *ComedySportz*, or *Wild 'n Out*; it could also be done to tell stories, like *Middleditch and Schwartz*. Our meetup, which is central Ohio's longest running (and free!) weekly comedy event, brings the games (and occasionally different forms) for you to play in a safe, supportive, and compassionate environment. Not only is it a lot of fun, but you get to work on thinking faster on your feet, plus it's an excellent way to meet new people and make friendships that'll last a lifetime! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "Yes, And" that you'll have fun!

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

Some trained COUNT volunteers work together once a month at RMH (http://www.rmhc-centralohio.org/volunteer.php) as Housewarmers (usually on the 1st Sunday from 1 – 5 PM). Some schedule other shifts at their convenience. You may try this out with less fuss by following a "Fast track" or go through the normal process. Fast track • Arrange a time to shadow a COUNT volunteer. Call Dave Nohle at 614-268-9558 (cell). • Show up and try it out. • Complete application, etc. later. Normal process • Complete an online application (http://rmhc-centralohio.org/volunteer/). • Attend orientation in advance. • At orientation you will complete forms agreeing to keep family/patient info private and allowing a background check and tour the facility. • Complete one training shift. Daily shifts are: morning 9 AM - 1 PM, afternoon 1 - 5 PM and evening 5 - 9 PM. • Schedule shifts online using the on the RMH scheduling system (http://www.volgistics.com/ex/portal.dll/?FROM=32895). The Ronald McDonald House (RMH) provides housing and meals for families with sick children. The Columbus RMH is the largest in the world with 137 rooms. COUNT has been volunteering there since May 2014. Housewarmers work with RMH guests to provide a home-like environment - greet, assist with family needs, answer phones, give tours, assist with checkin/checkout, prepare guest rooms after checkout, clean facility, laundry, restock supplies and staff the front desk. RMH Housewarmers volunteer at least one four-hour shift a month. All Housewarmers must complete an application and agree to a background check before they can be full fledged volunteers.

**The Behavior Gap: Where Products Win or Lose** Teams today have more data than ever, and yet many still struggle to understand why customers adopt, engage with, or abandon their products. Teams sprint, ship faster, and chase more signals… all while metrics stall and confidence drops. The missing piece isn’t more data. It’s often the behavioral insight between the metrics, explaining why the numbers move in the first place. Dashboards can tell you what customers did, but understanding why they did it (and how to influence what they do next) requires a deeper blend of insights. This session is about closing that gap. Drawing from real-world experience designing and scaling products as [ZoCo Design](https://zocodesign.com/)’s CEO, [Lacey](https://www.linkedin.com/in/laceypicazo/) will share how to cut through the noise and identify the insights that actually change behavior—moving people, and moving metrics. You’ll learn: * Why understanding customer behavior is a quant and qual challenge * How to spot the signals that actually predict behavior change * Where AI accelerates insight, and where it creates distraction * How to get meaningfully closer to customers, without adding more tools This talk reframes how to evaluate performance and identify what levers actually improve it, helping your team to make smarter bets with greater confidence. Every meaningful outcome is driven by behavior change. And when you know how to design for behavior, you stop guessing, and start building things that work. **About Our Speaker** [Lacey Picazo](https://www.linkedin.com/in/laceypicazo/) is the Founder and CEO of ZoCo, a healthcare product studio that turns complex, high-stakes ideas into products that drive real-world adoption. She partners with healthcare organizations to uncover critical care delivery insights, focus product strategy through behavior design, and build solutions that patients and providers actually use.
