Hendrik Klug is joining us to give a talk on the work he has been doing at Synthara to enable their in-memory compute IP using an MLIR-based stack. As usual there will be pizza, snacks, beer, and soft drinks after the event for participants, sponsored by Prof. Zhendong Su and the Advanced Software Technologies (AST) Lab at ETH Zurich. **Abstract:** Licensing custom accelerators as IP to chip makers comes with all sorts of challenges for the compiler. In particular, compute-in-memory hardware moves computation into the memory hierarchy, which requires a different kind of scheduling than conventional compilation pipelines usually perform. Synthara's computeRAM is an in-memory compute IP that is integrated into a wide range of targets, from smartwatches to datacenter accelerators, and each chip maker brings their own toolchain. So computeRAM has to come with a compilation pipeline flexible enough to plug into whichever platform compiler the chip maker is developing, schedule the memory hierarchy and compute capabilities exposed by the hardware, and stay maintainable as the IP evolves. MLIR's dialect and transformation model lets us integrate into the customer's compilation pipeline rather than replace it, and the same pipeline can be retargeted as the integration surface changes from one chip maker to the next. In this talk we walk through the MLIR pipeline we have built around computeRAM at Synthara: the hardware and the platforms it integrates into, the lowering pipeline to both LLVM and EmitC, and the optimizations we do for computeRAM. Throughout, we share what we learned: the good, the bad and the ugly of what's available upstream. **Location:** The event is taking place in the room G51 in the CAB building of ETH Zurich at the Zentrum campus. Enter from Universitätstrasse 6.

AI is changing the way we develop software. Mattia’s talk takes a fresh look at **Type-Driven Development** (TDD), and how types facilitate not only the work of human developers but also **LLM reasoning**. The talk with be hands-on with code examples and open discussions Agenda: * What is Type-Driven Development * An overview of F#’s type system * How TDD facilitates human developers with AI tools * LLM Tooling with types * LLM reasoning with types * Compositionality and reasoning traces Mattia is a data scientist fighting a losing battle: replacing Python with languages featuring richer type systems. As the co-founder of Entropy42, a Zurich-based startup, he specializes in the verification of ontologies and mathematical optimization programs. There, Mattia leverages type systems and provers to sharpen the performance of specialized small language models. Mattia will use F#, but his talk does not require any prior experience with the language.

Hey Zürich, we are not slowing down! Angular Zürich is back with another evening of exciting talks exploring the future of Angular, modern developer experience, and where the framework is heading next. And for the first time ever, we’ll have three speakers sharing their insights, ideas, and real-world experiences with the community. **Talks:** *Even moar Angular skills for agentic development* *by Tomas Trajan* AI agents are quickly becoming part of the Angular development workflow - generating components, refactoring code, writing tests, and even orchestrating full features. But getting reliable results requires more than good prompts. In this talk, I’ll share the Angular patterns, architecture decisions, and tooling techniques that make agentic development actually productive at scale. You’ll see how strong typing, standalone APIs, signals, and clear project structure dramatically improve AI-generated code quality, and learn practical workflows for collaborating with coding agents without sacrificing maintainability or developer control. \-\-\- *From Typos to Type Safety — Building a Typed Router for Angular* *by Dominic Bachmann* Route enums, path constant objects, flat route trees to avoid nesting complexity — Angular developers have invented all kinds of workarounds to bring some safety to navigation. But they all share the same problem: a second source of truth that you maintain by hand. In this talk, I'll share how I built angular-typed-router, a drop-in replacement that infers every valid path directly from your route configuration. You'll see the developer experience in action — full autocomplete, compile-time validation — and learn how interface augmentation, template literal types, and recursive conditionals make it work at zero runtime cost. \-\-\- *Angular 22: The Great Simplification* *by Mateusz Halada* Angular has spent the last few releases removing complexity piece by piece - and Angular 22 takes that vision even further. In this talk, we’ll explore how the framework is evolving toward a leaner, more intuitive developer experience with simpler APIs, stronger defaults, and less boilerplate across everyday application development. You’ll see what’s new, what’s been streamlined, and how modern Angular patterns around signals, control flow, routing, and reactivity fit together into a much more cohesive mental model. By the end, you’ll understand not just the new features, but the bigger direction Angular is heading in. **Agenda** * 18:00 - 18:15 – **Intro** * 18:15 - 18:45 – **Tomas Trajan** \- Even moar Angular skills for agentic development * 18:50 - 19:30 **Dominic Bachmann** \- From Typos to Type Safety \- Building a Typed Router for Angular * 19:35 - 20:05 – **Mateusz Halada** \- Angular 22: The Great Simplification * 20:05 - 21:00 – **Networking**

**Build Your First AI Agent with TypeScript** ─── No slides. No theory. Just code. This is the first session of Zürich Agent Lab — a monthly hands-on workshop community for engineers building AI agents in Zürich. We start on June 17th with the fundamentals: building a real AI agent from scratch using TypeScript and the Vercel AI SDK. ─── **Format** **5:30pm — Doors open and get comfortable (30 min)** **6:00pm — Hacking (2 hours)** You write code. We build together. Step by step, you'll implement a working AI agent with tool calling, structured outputs, and a controlled agent loop. Bring your laptop and a free OpenAI API key. **8:00pm — Demos + Knowledge Sharing (30 min)** Show what you built. Share what you learned. Ask what you couldn't figure out. This is where the room gets interesting. **8:30pm — Networking** Stay as long as you want. ─── **What you'll build** • An agent that calls real tools to answer questions it couldn't answer alone • Structured outputs that make your agent's responses predictable and usable • A controlled agent loop with proper step limits ─── **What you need** • A laptop with Node.js installed • A free OpenAI API key (usage will be minimal) • Comfortable with TypeScript basics **Food and Drinks** • Pizza will be delivered by 6:30 PM • Drinks will be unlimited ─── **25 seats only.** RSVP secures your spot — no walk-ins. This event is CHF 75. If you want year-round access to all sessions, founding memberships are open at CHF 900/year for the first 50 members.

No slides, no schedule. We're meeting up for a relaxed ZurichJS summer meetup with drinks, barbecue, and people who build things. If you’re shipping an AI tool, a vibe-coded side project, a SaaS product, or an existing app that could use a better business model, bring it along. We’ll hang out, compare notes, and brainstorm how to turn useful software into something that actually makes money. Let's get the bbq going with beers and geeks. Important: this is a potluck edition. Bring your preferred barbecue option (and maybe some extra to share if you want), some picnic blankets or picnic chairs, anything that you'd normally bring to a picnic.

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way.
