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.

### **CROSSING THE RUBICON** Have you ever made a choice that changed everything? A moment where the door slammed shut behind you, and the only way out was going through? On Thursday, April 30th, we are gathering for a ZST mainstage evening of true stories about those life-altering leaps, irreversible decisions, and the glorious (or disastrous;-) aftermath of saying "why not!" "*Ships are safe in harbor, but that’s not what ships are built for.*" — John A. Shedd ### **ARE YOU ALL IN?** We’ve all stood on that edge. Maybe it was the moment you finally hit "un-subscribe" from an unfulfilling job, the night you committed to a FWB "situationship," or that impulsive decision to move outside the city where there's only one bus per hour. Once you roll the dice, there’s no turning back. Whether you ended up exactly where you needed to be or found yourself in a completely unexpected reality, we want to hear your truth. ### **MOMENTS OF NO RETURN:** * **The Leap of Faith:** That career pivot or international move that felt like jumping without a parachute. * **The Bridge Burned:** When you finally stood your ground, spoke your truth, and knew things would never be the same. * **The Point of Impact:** A split-second decision—heroic, hilarious, or heartbreaking—that changed forever who you are today. ### **JOIN THE FRAY** Whether you’re a seasoned teller or just realized you have the perfect story while reading this, your voice belongs on our stage. Not ready to bare your soul? Come for the drama, stay for the community, and help us vote for the "Best Storytelling of the Night.

**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!*

Join us for a day of photographing a variety of racing cars and motorbikes at this hillclimb event at Mutschellen (between Dietikon and Bremgarten). Although competitive racing (and specifically overtaking) are not allowed in Switzerland, there are occasionally some opportunities to see some racing cars and this is one. There is a paddock at the bottom where the cars and bikes are prepared and set off in groups up the hill. You can stand in various locations along the route. There are usually some stands selling food and drinks. **Tickets**: CHF20 per person, payable to the event organisers (not PICZ!) on arrival. If coming by car, **parking** is an additional CHF7. **\*\*if this Meetup event is full, of course you can come as a private individual, it may be difficult for more than about 10 members of the club to meet up and stay loosely together!\*\*** **You will need:** * Your camera (preferably with good predictive autofocus) * A variety of lenses, from standard or even wide angle for the paddock, to telephoto to follow the cars and bikes up the hill. * Advisable to bring at least something to drink, you may wish to bring your own lunch too. * Suitable shoes for walking/hiking, there are paths and also grassy fields, there may be some mud. * Clothes: the weather can be variable at this time of year, could be anything from rain to strong sunshine or a mix of both! **Meeting up:** I suggest we try to meet close to the paddock (before the start line) in the morning, although this can be noisy when the engines are started. I will create a WhatsApp group for participants. **Getting there:** * By car, there are temporary car parks in the fields typically on the north end of the site. Look for Bahnhof Rudolfstetten on your SatNav and then follow the signs to the car parks. * By public transport, travel to Bahnhof Rudolfstetten near Berikon & Widen, for example from Zürich HB, zou could take the S12 towards Brugg at 09:14, followed by he S17 at Dietikon at 09:33 to Rudolfstetten. * Please be aware this will be a very busy public event and you may need to queue to buy tickets to get in, so allow time to arrive and meet the group.
