Most of us, irrespective of diet, culture, or political affiliation, say that we care about how animals are treated and consider animal cruelty to be unacceptable. Many of us would like to contribute, in whatever ways seem feasible, to improving farmed animals' living conditions and alleviating some of their suffering. This event is about making it easier to help, through knowledge and shared understanding. 🌱 **Why is this importan**t?: Cruel but standard farming practises such as confinement cages and routine mutilations practices continue to affect hundreds of billions of sentient animals every year. The number of animals killed each year is more than the total number of humans who have *ever existed*. Many philosophers, ethicists, and researchers regard the degree and scale of the caused suffering as one of the most serious and neglected moral problems of our time. This event, which combines a structured lecture 🎙️ with a collaborative discussion 💬, is an opportunity to look more closely at some proven, effective strategies to address the problem. It will be presented by **The Humane League's** Research Lead **Giovanni Fabris** and Principal Strategist **Leo le Ster,** who will offer an inside look at how animal welfare campaigns are designed and what makes them succeed. **About The Humane League** 🌍: The Humane League is one of the most effective animal welfare organisations in the world, working to end the abuse of animals raised for food through corporate campaigns and policy change. Thanks to their work and that of their allies, cage-free hen production in the US rose from around 3% to nearly 46% over 15 years. **Helping animals beyond individual choices:** Individuals can help animals in many ways — changing their diets, donating to impactful organisations, or volunteering. Being vegan is one of the most direct ways to withdraw personal support from systems that cause animal suffering. But some of the highest-impact opportunities lie in shifting institutions and corporate policies — work that most people are entirely unaware of, and that this evening will shed some light on 💡. **Logistics** 📍: We meet directly at ETH Zurich HG E41 on Tuesday, 28 April, at 6.15 p.m. (please be on time!). After the talk, there will be a chance to discuss and socialize over vegan pizza. 🍕 **You don't have to be vegan to join:** As always, this event is ***open*** to everyone — and ***relevant*** to everyone. Whether you are fully vegan or nowhere near it, there are plenty of meaningful ways to contribute to this cause, and this evening is a good place to start figuring out what that might look like for you. 🌱

**INNOtalk #19** presents **"When Agile Isn’t Enough: A Fortune 500 Journey to Serial Product"** *«Beyond the Spotify Model: Real-World Innovation in Hardware & Electronics»* Innovation is no longer the challenge - making it real is. Many organizations invest heavily in innovation, agile frameworks, and transformation programs. Yet too often, initiatives remain stuck in pilots, labs, or presentations - without ever translating into real business impact. This INNOtalk takes you inside the journey of a Fortune 500 automotive leader that broke this pattern. Within just 18 months, the company moved from early-stage innovation efforts to serial production in a completely new market segment - turning ideas into tangible business value. Instead of focusing on frameworks or buzzwords, this session reveals what truly makes the difference at executive level: \- How to navigate the realities of innovation in regulated\, hardware\-driven environments\. \- How to build structures that balance speed\, safety\, and compliance\. \- And how leadership decisions determine whether innovation remains an initiative \- or becomes a growth engine\. At the core lies a simple but powerful insight: \- What works in software does not automatically work in the real world\. This session challenges common assumptions around agile and introduces a pragmatic, hands-on approach to innovation - designed for organizations where complexity, regulation, and engineering excellence are part of daily business. **What you will gain:** 🔷 A clear perspective on why traditional agile models often fall short in hardware and regulated environments 🔷 Practical insights on how to move from experimentation to scalable, market-ready solutions 🔷 Leadership impulses to turn innovation into measurable business impact **SPEAKER** [Björn Persson](https://www.linkedin.com/in/bj%C3%B6rn-persson-a6325710/ "https://www.linkedin.com/in/bj%C3%B6rn-persson-a6325710/") *Product Management Advisor & Consultant at «ProAgile»* Björn Persson is a seasoned Product Management Advisor and Agile Transformation Expert with over 20 years of experience in driving innovation across teams and organizations. Björn has supported companies in translating agile principles into real-world impact - particularly in complex, regulated, and hardware-driven environments. As a consultant at ProAgile, Björn focuses on bridging the gap between strategy and execution, helping organizations move beyond “innovation theater” toward scalable, production-ready solutions. His work combines deep practical expertise with a strong understanding of leadership, organizational design, and business value creation. **DETAILS** 🗓️ Date & Time: **Tuesday, April 28, 2026 / 17:00 - 19:00** 📍 Location: **swissICT – Vulkanstrasse 120 – 8048 Zurich** **AGENDA** 16:45 - 17:00: Arrival & Welcome 17:00 - 17:30: Keynote: "When Agile Isn’t Enough: A Fortune 500 Journey to Serial Production" by Product Management Advisor & Consultant at «ProAgile» 17:30 - 18:00: Interactive Q&A (Focus on leadership and implementation). 18:00 - 19:00: Networking & Community Discussion 19:00: Closing of Event **TARGET GROUP & LANGUAGE** • C-level and Senior Executives within industrial, automotive, and regulated environments.

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.

We're planning the next Hackergarten Zurich 🥳 We're looking forward to see some familiar faces and share knowledge within the open-source community. Spread the word — everyone is welcome!

**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!*
