Ergänzende Infos: Salsa! Kein anderer Tanz hat in den letzten Jahren eine derart steile Erfolgskurve aufs Parkett gelegt. Die Salsa weckt Sehnsüchte nach der Karibik und versprüht wahre Lebensfreude. Salsa wird paarweise getanzt. Ein Partner führt, der andere wird geführt. Bei uns werden hauptsächlich Kurse im kubanischen Stil unterrichtet, der Salsa Cubana, welcher seinen Ursprung in Kuba hat. Die kubanische Salsa wirkt eher spielerisch, rhythmisch und lebendig und setzt sich aus unterschiedlichen lateinamerikanischen Rhythmen und Tänzen zusammen. Das wesentliche Merkmal des kubanischen Stils sind die Drehungen des Tanzpaares um einen gemeinsamen Mittelpunkt und das Kernstück des Salsa Cubana, die Rueda de Casino. Der Name Rueda rührt daher, dass alle beteiligten Paare einen Kreis bilden, wobei sie jeweils synchron die gleichen Figuren tanzen. Bedingt durch Partnerwechsel, die jeweils zu den getanzten Figuren gehören, dreht sich die Rueda bzw. das Rad. Der Kurs für blutige Anfänger oder für Leute, die sich mit den Basic-Elementen noch unsicher fühlen.

Welcome to the Zürich AR/VR/Spatial Computing Group. Tonight, we are joined by Tianyi Xiao, a fourth-year PhD candidate at ETH Zürich’s geoGAZElab. Tianyi develops XR-based immersive 3D sketching interfaces that serve as both creative instruments for architectural design and tools for investigating human spatial cognition. His research, frequently featured at the prestigious ACM CHI conference, explores how generative AI can create seamless sketch-to-model pipelines. Key projects include Sketch2Terrain, an AI-driven system that allows non-experts to create to sketch accurate maps of natural landscapes in Augmented Reality, as well as Sketch2Model, a creative tool that enables the conversion from 3d sketches into 3D furniture in Extended Reality. Following the talk, we are going to have a hands-on session to try the Sketch2Model tool. This event: 19:30 Opening of door Z0.03 20:00 Main talk: Immersive 3D Sketching by Tianyi Xiao 20:30 hands-on session to try the Sketch2Model tool.

Angular Zürich is back this April with two exciting talks exploring the future of Angular and modern application architecture. In the first talk, **Tomas Trajan** presents *“Embracing agentic future with Angular Skills & MCP”* He will explore how Angular is evolving in the age of intelligent, agent-driven systems, and what skills developers need to stay ahead. Expect insights into modern Angular capabilities, emerging patterns, and how MCP and agent-based approaches are shaping the future of frontend development. The second talk by **Mateusz Halada**, *“Gone without a Zone - Understanding Zoneless Angular”* dives into one of the most important shifts in Angular’s evolution. You’ll learn what it means to go zoneless, why it matters for performance and developer experience, and how to approach building applications without Zone.js. Join us for an evening of forward-looking Angular topics, practical insights, and great discussions with the community. **Agenda** * 18:00 – **Doors open** * 18:15 - 18:30 – **Intro** * 18:30 - 19:00 – **Tomas Trajan** \- Embracing agentic future with Angular Skills & MCP * 19:05 - 19:45 – **Mateusz Halada** \- Gone without a Zone \- Understanding Zoneless Angular * 19:50 - 21:00 – **Networking**

Welcome back to Papers We Love, Zurich! In this session, Daniel Galán Pascual, a PhD student in the Information Security group at ETH Zürich, will present "**A Gentle Introduction to Ownership Types in Rust**". Ownership types are what give Rust its memory safety guarantees: the compiler statically rules out entire classes of bugs (use-after-free, data races, dangling pointers) with no garbage collector and no runtime cost. Through worked examples, the talk builds a working understanding of ownership in practice, drawing on the conceptual model of "[A Grounded Conceptual Model for Ownership Types in Rust](https://arxiv.org/abs/2309.04134)" and its accompanying Aquascope tool. **Why care?** * ***For systems programmers***: ownership types are a general approach to resource management that shows up across many languages, with Rust being the most prominent industrial example. The intuition you build means finally making sense of borrow checker errors when they matter most, both in Rust and beyond it. * ***For PL and type-theory enthusiasts***: ownership types have deep connections to linear and affine type theory. Seeing them in an industrial language reveals how theory meets real-world complexity. The talk will be 45-60 minutes, followed by discussion, Q&A and snacks. No prior background in type systems or Rust is required. However, basic systems programming background will be beneficial.

**Most products are designed to move people in a certain direction.** But when it comes to behaviour change, pressure and punishment **often** **backfire.** They may create short-term compliance, but they can also leave users feeling guilty, frustrated, or simply ready to give up. **In this talk, Mi Xue Tan explores how UX can support lasting behaviour change through positive reinforcement.** Instead of designing systems that fight human psychology, she looks at how we can build experiences that work with it — reducing resistance, creating motivation, and supporting small steps that add up over time. This matters for the UX community because every product shapes behaviour. When we design with human needs and motivation in mind, retention does not have to be forced. It can emerge more naturally through experiences that feel supportive, effective, and genuinely human. **[Mi Xue Tan](https://www.linkedin.com/in/mi-xue-tan-3030b5120/)** works at the intersection of data, user research, and human behavior. With a background in data science and UX research, her work xplores how thoughtful design and positive reinforcement can support meaningful behavior change. Her focus: using data, psychology, and good communication to **create experiences that people don’t just use — but stick with.** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- 💬 The Talk is in **English** 📍 The event will be held at ETH Zürich Maschinenbau ML, **Room F36** We kindly ask you to arrive *10 minutes* early of the event start, so everyone can find a seat due to high attendance. *Thank you!*
