As the relentless heat wave continues to bake the streets of Zurich, we invite you to escape the glare of the city and step into a space where the air is heavy with a different kind of intensity. In the cool, quiet halls of the **Kulturhaus Obere Stube**, a layered world unfolds in which grief is not only felt, but also questioned as experience: as a possible form of knowledge whose recognition cannot be taken for granted. «The Shroud 2026» is not merely a technical showcase; it is a haunting, immersive encounter with Seraina’s fate — a mother’s loss seen through a fractured state in which grief is already distorted by silence, self-doubt, displacement, and the pressure of a world unable to meet it on its own terms. This experience is brought to life through the multi-disciplinary artistry of Alexander Vögeli, a media artist whose work seamlessly spans the physical and digital realms. Serving as the project's architect, Vögeli’s vision encompasses everything from the initial research and concept to the art direction, technical programming, and dramaturgy. Through the delicate interplay of a physical book and a digital veil, you enter a space in which Seraina’s loss is mediated through silence, self-doubt, displacement, and distortion.The atmosphere of this world is further textured by the sound design of Jan Meier, while the voices of Francesca Ruch, Jan Meier, Leon Zahler, and Maya Lewandowski breathe life into the narrative, making the presence of Seraina and the AI mourning companion feel both intimate and unsettling. Additional technical assistance was provided by iffn and Melvin Sprenkels. Together, these contributions craft a space where grief becomes a point of departure for questioning how we, and our technologies, respond to loss, mourning, and experiences that seem to resist easy understanding. **Join us in Stein am Rhein from July 6th to July 12th** to explore this intersection of mixed reality, literature, mourning, and technology. Let’s leave the burning sun behind and enter a world shaped by loss, mourning, technology, recognition, silence, and the fragile conditions of understanding.

While the rest of the planet loses its mind over the World Cup 2026, ROBIN’s becomes the one venue in Zürich with a microphone in the middle instead of a trophy. **Tickets at [https://inyourfacecomedy.ch/offsidecomedy/](https://inyourfacecomedy.ch/offsidecomedy/)** Offside Comedy is a new summer night of English standup hosted by **[Harry Fücks](https://instagram.com/harryf.cks)** and **[Chris Darwa](https://www.instagram.com/chrisdarwa/)**, two faces you’ll know if you’ve spent any time at Zürich’s English comedy shows. Every Tuesday during the summer they bring two more comedians to the stage, and yes, there’s a scoreboard of sorts: each act is playing to win the room, and the audience decides who takes the night. We keep the rules about as seriously as a referee keeps a clean sheet, so expect the format to wander off somewhere around the second pint. No offside trap, no Video Assistant Referee, no penalties (well, maybe one or two verbal ones). Just sharp English comedy from people who’d rather hold a mic than a ball. Doors open 7:15pm. The only own goal is staying home. **Tickets at [https://inyourfacecomedy.ch/offsidecomedy/](https://inyourfacecomedy.ch/offsidecomedy/)**

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).

**Speakers:** Paulo Martins (GitLab) – **We Tried to Detect Indirect Prompt Injection in Coding Agents. Here’s What Broke** Gianlorenzo Occhipinti (Exa) – **Beyond the Knowledge Cutoff: Agentic Search in Practice** Marius Colacioiu (Norm) - **Your Repo Is the Memory: Durable Context for AI Coding Agents** **Agenda:** 17:30-17:40 – Welcome & intro 17:40 – 18:10: Paulo Martins 18:15 – 18:45: Gianlorenzo Occhipinti 18:45 – 19:15: Marius Colacioiu **Abstract**: **We Tried to Detect Indirect Prompt Injection in Coding Agents. Here’s What Broke** 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. \-\-\- **Beyond the Knowledge Cutoff: Agentic Search in Practice** An LLM is a lossy compression of the internet: the long tail gets blurred, concepts interfere, and anything after the training cutoff simply doesn't exist. The fix isn't a bigger model, it's giving agents the ability to search. This talk walks through the shift from classic retrieve-then-read RAG to agentic search, where the search engine becomes part of the agent's environment and the model learns what, when, and how to query: decomposing questions, parallelizing searches, and chaining multi-hop lookups \-\-\- **Your Repo Is the Memory: Durable Context for AI Coding Agents** AI coding agents are becoming useful fast, but they still do not know the local truth of your codebase. This talk shows how to make repo-local context durable so agents produce work that fits the project and humans can still understand, review, and maintain what gets merged.

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!

We're planning a hands-on technical session focused on building AI solutions in ServiceNow - think skills, agents, and real-world use cases. If you’re curious about AI on the platform, RSVP now and stay tuned for more details. Let's build together!

Highlights and Hidden Gems in SQL Server 2025 With so much emphasis on cloud data platforms and AI these days, SQL people can feel left behind by all the marketing hype. SQL Server 2025 was officially released in November of 2025, though, and contains a ton of improvements that will make our SQL Server deployments a bit faster, better, and more secure. There are even more improvements tucked into the release that never made a marketing blog or press release that you'll likely be learning about for the first time in this session! Join this session to learn about what makes your high availability a little more available, your performance a bit more performant, and your database more developer and app-friendly. Come spend an hour with SQL people talking SQL Server 2025 – the good, the "not quite ready for prime time", and the hidden awesomeness.

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

This presentation will be by Ben Iten, humanist chaplain and HCCO Board Member. Speaking on expressing Humanism values in American democracy. This meetings will be hybrid. You can meet us in-person or attend online. The formal presentation will start at noon. Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event.

**Practical Curiosity: Learning from Everyday Data** How do we actually get better at utilizing our day-to-day data? Fancy dashboards and complex models might look nice and draw attention, but that’s not where most of us spend our time. In fact those shiny outputs frequently sit unused, while the real insights are drawn from the analyst’s daily practice. Sometimes it’s as simple and as powerful as noticing that a segment is shrinking, a channel is underused, or certain links keep getting all the clicks. There’s many different places that the spark of insight can come from, but you have to keep your head in the data and know where to look. In this session, we’ll explore real-world examples of how segmentation, testing, and click behavior can uncover practical digital marketing opportunities. You’ll leave with inspiration for your own use cases, along with a few simple ways to ask better questions, spot meaningful patterns, and make smarter decisions without overcomplicating it. **About Our Speaker:** [Elaine Armbruster](https://www.linkedin.com/in/elainearmbruster/) is a Director of Digital Experience at the [American Diabetes Association](https://diabetes.org/), where she focuses on using data and insights to create smarter, more effective digital experiences. A lifelong Columbus resident, she has built her career in email marketing and the broader digital user journey, and is finding she most enjoys working in the messy middle where systems, data, and big ideas don’t quite line up yet.
