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.

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.

**5th February - DotNet Zurich @ Isolutions** *Join us in person at Isolutions!!* This event will happen at Isolutions, The Circle. **Agenda:** * 17:45 Reception open & networking moment - note that if you come earlier we might ask you to help with the setup ;) * 18:00 Intro Hosts & .NET Zurich * 18:15 – 19:05 How to securely implement MCP with OAuth in .NET * 19:15 – 20:05 Swiss Identity in .NET: A Practical Guide to EIAM, aGov, SwissID, Entra ID—and Social Logins * 20:15: Pizza & drinks The event is held in English. **More detail & full excerpt of the talks & bios:** * **Title: How to securely implement MCP with OAuth in .NET** * **Abstract:** In this session, we’ll explore Model-Context-Protocol (MCP). We’ll begin with a high-level overview of MCP, illustrating its core concepts through a practical implementation using Semantic Kernel in .NET. From there, we’ll shift focus to security. We’ll examine common vulnerabilities in MCP-based architectures and demonstrate how to securely implement it using OAuth. Whether you're new to MCP or looking to deepen your expertise, this session will equip you with both the conceptual understanding and hands-on techniques to build secure AI solutions. * **Speakers:** * **Cédric Mendelin** As a seasoned full-stack developer with 8 years of experience, Cédric is fuelled by a passion for .NET, Azure and especially AI! He is dedicated to crafting valuable and secure solutions for end users generating true business value. Located in Basel, Switzerland. * **Raffael Nussbaumer** Raffael is an experienced .NET developer and Azure enthusiast. His experience in developing robust applications with solid craftsmanship is complemented by strong interest in modern DevOps practices and security. * **Damien Bowden** Damien is a web developer, architect and a Microsoft MVP for Visual Studio Development Technologies, Sonar Navigator who loves to learn. He contributes regularly to open-source projects on GitHub and Microsoft ASP.NET Core docs. He runs a very popular blog which focuses on ASP.NET Core, application security, Entra and Angular. * **Title: Swiss Identity in .NET: A Practical Guide to EIAM, aGov, SwissID, Entra ID—and Social Logins** * **Abstract** Modern Swiss apps rarely authenticate just one way. In this fast paced, concept-level session, we compare how to plug EIAM, aGOV, E-ID, SwissID, Microsoft Entra ID, and social providers (Google, Microsoft, Apple, Facebook) into software systems using OpenID Connect/OAuth 2.0 (and where SAML still fits). You’ll see side by side integration patterns and what each IDP means for user experience, assurance levels, consent, data residency, and compliance. We’ll finish with a simple decision matrix—when to choose which IDP, so you can ship secure sign in flows that match your audience, not the other way around. * **Speakers bio:** * **Thomas Aebi** Tom is a Solution Architect with a strong focus on Microsoft technologies. He has joined the party from the early days of .Net and later with Azure, too. He always strives to build a smart and lean solution consisting of already available services, complemented with code as needed. He loves to inspire others and share his knowledge. * **Marc Rufer** Marc is a passionate software engineer, living in Switzerland and interested in DevOps, DevSecOps, application security, web development and Azure. His favourite tools, technologies and standards are GitHub, Azure DevOps, ASP.NET Core, Git, Terraform, PowerShell, OIDC, SQL, EF Core, REST. * **Andres Bohren** Andres works as a Senior Microsoft Cloud Engineer/Architect for midsize to large Enterprises at isolutions in Switzerland. He has a special focus on M365 including Identity, Messaging, Communication, Security and PowerShell but also some Azure Technologies. He is Co-Organisator of the Microsoft 365 Community Schweiz Meetup group and was Speaker at several other Meetups or Conferences. He likes good Food, his Bike and nice Dive spots all over the World.

Hare (someone to set the route) is Her Majesty! Come join us! Expect a short and shitty live hared trail! **Where**: Meet at HB Lockers **When:** We'll meet at 6:50 pm to start at 7:00 pm. There's a charge of CHF 5 for participating, which covers all you can drink beer/cider (and non-alcoholic alternatives) plus snacks afterwards. **All Welcome:** If you are new, curious, and want to get out of the house, stretch your legs, talk shit, enjoy a drink, and hopefully a laugh, then here's what you need to know: • We are a social running/walking group, physical fitness is not required, but a sense of humour is useful. • The aim is to find the '*Beer Stop*' at the end of the '*trail*' and have fun. • 'True Trail' is typically 4-7 km. Some will go less (especially those walking or walk/running), and some over-achieving fast runners will go further. • The '*Hare*', which changes each event (along with location), cleverly lays the trail (typically with flour marks) so that everyone reaches the end at the same time. • There is always a place to deposit your bag and sometimes a place to change. • **After Trail**, we group for \~20-40 minutes for drinks, snacks, and some fun. This '*Circle*' is typically outside, so leave something warm in your bag in winter (and bring a flashlight when it's dark). If you don't want to stand around drinking afterwards, you can head home. We occasionally all go to a restaurant afterwards. **Why bother leaving your warm & dry sofa?** If you enjoy getting outside, being around people, and doing something a bit different, you will probably enjoy hashing. Exercise is important, and this is probably the least boring way to get it. 'Hashing' and the idea of some physical activity to work up a thirst, have been around for almost 90 years and there are groups (*Hashes*) in most major cities. Its humor and 'traditions' can be explored on the internet - **or you can just come along and find out.** *See you there.* We are of many nationalities, all ages, full of misfits and idiots (at least there is no one taking themselves seriously!) and always welcome newbies 'Virgin Hashers' and visitors from other groups.

Welcome cold lovers! We have been practising cold water plunges for over 4 years. We believe in the benefits of cold water exposure. The feeling you get after the swim is magnificent, it makes you feel alive. We have started this group to safely experience the cold water together. We motivate each other, do active warmup exercises, and also share our life stories with a warm coffee/tea afterwards. The event is every Sunday at 11:30, we meet at the Mythenquai Badi entrance no matter the weather. Take along: a large towel, comfortable bathing suit, flip-flops, and warm clothes (hat, gloves, etc). If you’re planning swimming out take along a bright swim buoy. The event is Free. IMPORTANT: Every participant takes responsibility for themselves when attending this event. Before attempting cold water exposure, individuals with health conditions (e.g., heart problems or hypertension) should seek advice from a healthcare professional. Safely acclimating the body to cold temperatures requires preparation and gradual exposure.
