**Sponsored by:** ***\- ACP*** ***\- TD SYNNEX*** ***\- Technopark Winterthur*** **Partner-led and partner-branded by**: ***Microsoft*** Speakers: * Firas Cheaib (ACP) – When Models Become the Commodity * Victor Chibotaru(LogicStar AI) – Shipping Faster, Drowning Sooner Abstract: When Models Become the Commodity ACP Engineering works extensively with LLMs to write production code across a small team. What makes that work is not the models, but the groundwork laid before them: a portfolio of Python projects sharing the same tooling, structure, tests, CI, and linters, the same conditions that already made the codebase easy for humans to navigate. That foundation is what powers the current build of ACP-M, ACP's industrial IoT platform for manufacturing customers, and an early agentic-loop prototype now running internally. The next step is enabling customers to automate their own operations the same way. Doing that requires the same kind of preparation on their side: turning fragmented operational data into knowledge graphs, unified namespaces, and typed semantic layers, so that agents act on information that is short, focused, and reliable. Once that environment exists, the model becomes a commodity. What matters is enterprise processes and domain knowledge, not which model happens to be in fashion that quarter. Attendees will leave with a concrete way to assess whether their own environment is ready for agents at all, and what it takes to get there -- Shipping Faster, Drowning Sooner AI ships your features faster than ever, but it also ships bugs faster than ever. Code got cheap, maintenance didn't: customer complaints stack up, Sentry alerts overflow, and triaging the pile is still as expensive as it ever was. I'll show how LogicStar finds bugs across your Sentry, Jira and codebase, separates signal from noise, and helps your team fix issues that matter.

**Kon-Tiki Comedy Tuesday!** Zurich's longest standing weekly Comedy Night : English Standup at Kon-Tiki Bar since 2018! **Tickets :** [https://shorturl.at/fgjmM](https://shorturl.at/fgjmM) Kon-Tiki Comedy has long become a staple of Tuesday Nights in Zurich! Veterans, regulars, amateurs & newbies from all around the world show up to make people laugh. This Comedy Open Mic is regularly Hosted by Ahmet Bilge. Kon-Tiki Comedy is the place for English Standup in central Zurich. Come join & laugh with us! **Early Show starts at 19:30 pm** **Frequently Asked Questions:** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **Q: Is the show in English?** A: YES. Kon-Tiki Comedy is always in English. **Q: What's the difference of a Comedy Open Mic from a regular Comedy Show?** A: Anybody who wants can go on stage at a Comedy Open Mic. A bunch of Comedians will be there, but they will be trying out jokes, because this is how Comedians find out if something is funny or not, so you get to be there at the birthplace of jokes. Often Comedy Open Mics are more casual & but also funny as well! **Q: Can I perform Comedy also?** A: Yes of course! Just contact theamericanstandupshow@gmail.com if you're interested in performing. Or directly go to the event page on facebook & write "SPOT" inside the event discussion. You'll be confirmed later & will get 5minutes to start off with. Anybody can sign up! **Q: What about these seats?** A : We have enough seats for everyone but the first come first served rule applies! Especially since Kon-Tiki Comedy is popular, often it is packed inside, so come early for good seats. What's early? Anything before 19:00 & you will have your seat of choice. **Q : What about the late show?** Depending on the turnout a late show is also available most of the time, please check the ticket page to see if there is a late show option. Basically if you can buy tickets to the late show, it's happening, if it's not an option for a ticket it's not! Both shows might be consolidated into one if there's not enough ticket sold for the late show. In this case you will recieve an e-mail telling you so. **Q : Can I refund my ticket?** There are no refunds allowed because it becomes too much work for a simple Comedy Open Mic, so only buy your ticket if you know you're for sure going to be able to make it. But if for some reason you can't make it, you are welcome to use your ticket for any future Kon-Tiki Comedy Shows. Just write an e-mail to exchange. **Q : Can I buy tickets at the door?** No please don't. Technically we can but it complicates everything, so just buy them online. Just to persuade you NOT to ask to buy at the door: Tickets at the door are 15.-CHF. Please buy online : ) **Q: Will it be funny?** A : You betcha. You can't do a regular show since 2018 & not be funny. **Any other questions:** Email: theamericanstandupshow@gmail.com with the title "Kon-Tiki Comedy" But if it's any of the questions covered by the FAQ above, I will still answer it, *but first I will insult you.* **Legal Disclaimer:** Comedians may film their sets as well as the audience during the comedy show. By buying a ticket you consent to being filmed in this public space. If you ever have a problem with any clip published online you are very welcome to contact us & ask to have it removed, we are happy to accomodate you. Thank you for your understanding.

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/

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.
