After a long hiatus of the compiler social, Lorenzo is joining us to talk about the exciting work happening at NVIDIA that you have probably heard about, namely cuTile/TileIR. As usual there will be pizza, snacks, beer, and soft drinks after the event for participants, sponsored by NVIDIA. **Astract:** GPU programming has evolved significantly over the past decade, driven by rapid hardware innovation such as Tensor Cores and new numerical formats. However, the gap between high-level productivity frameworks and low-level performance-centric programming models continues to widen. In this talk, we introduce cuTile and TileIR, a new block-level programming model and intermediate representation designed to simplify high-performance GPU development while preserving forward compatibility with evolving NVIDIA architectures. cuTile provides a tile-centric abstraction for data-parallel workloads, accessible from Python, while TileIR—an MLIR-based low-level IR integrated with CUDA—offers a stable, portable foundation for targeting tensor cores and future hardware generations. Together, they establish a middle ground between usability and control, enabling expressive kernel development without sacrificing performance. We present the programming model, illustrate it with examples, discuss performance considerations, and, if time permits, take a deeper dive into the core abstractions behind TileIR: https://github.com/NVIDIA/cuda-tile **Location:** The event is taking place in the room G61 in the CAB building of ETH Zurich at the Zentrum campus. Enter from Universitätstrasse 6.

**[Tickets here on Eventfrog](https://eventfrog.ch/jackpotcomedy)** **Down on your luck?** Perfect. Comedy works best on people with low expectations. At **Jackpot Comedy**, comedians test brand-new jokes alongside the ones that actually work. Some hit the jackpot, some crash out spectacularly. Either way, you win, because it’s funnier when anything can happen. Expect a proper underground comedy night, close to the stage, real crowd energy, and comics who are risking their dignity for your entertainment. Hosted by **[Jack Roberts](https://www.instagram.com/jackrobertscomedy/)**, a man who has invested his long-term financial stability entirely into making strangers laugh. We’re downstairs at **Bar OTRO,** just off Langstrasse, the ideal location for high-risk decisions you’ll be glad you made the next morning. No dress code. No awkward theatre seating. Just drinks, friends, and a very high probability of laughing harder than you planned. Roll the dice. Bring someone you like. Or someone you’re unsure about, this is an excellent test. **[Tickets here on Eventfrog](https://eventfrog.ch/jackpotcomedy)** **SHOW BEGINS AT 20:00 (Doors at 19:00)**

**Note from Callie:** *Originally a web serial - can be read on Royal Road or bought as an ebook in three volumes.* Hannah has a routine. Wake up, take a shower, go to school, go to work, come home, and pass out. It's a perfectly normal routine for a perfectly normal girl who does not have to remember how her limbs work every morning because of haunting nightmares of being a very different creature in a very different world. But that's all she thinks they are—nightmares—until one night they're all too lucid, and her body on Earth starts to change. Slowly, Hannah's humanity starts to slip away... but surely she can continue just sticking to routine, right? It'll be fine. It has to be. A mix of urban and traditional fantasy, Bioshifter is a story in two worlds, with magic leaking in from one to the other. It's a story about love, self-acceptance, neurodivergency, and a whole lot of trauma. Strap in and enjoy! ***\*\**** *The event takes place in the Library of the Regenbogenhaus, which is open from 15h00-19h00 on Wednesdays.

Join us for our next GraphQL Meetup on **March 12th** in Zürich! The event will start at **6:00 PM**, with time for networking and the first talk beginning at **6:30 PM**. Location, drinks, and food are generously provided by **Digitec Galaxus**. If you’d like to host one of our future events, please reach out to us at contact@chillicream.com. The event will be **hybrid**. We strongly encourage you to join us in person for the full experience, but we will also provide a livestream for remote attendees. When you sign up, please let us know whether you’ll attend in person or online. **Schedule** **18:00 – 18:30** Welcome & Networking **18:30 – 19:00** **GraphQL Batching: DataLoaders and Batch Resolvers Explained** \- Michael Staib GraphQL servers rely on batching to avoid the N+1 problem, but where should batching actually happen? In this talk, we explore three common approaches: DataLoaders, Batch Resolvers, and breadth-first (BFS) execution. While all aim to reduce redundant data fetching, they solve different problems and live at different layers of your stack. We will examine how each approach works, when to use one over the other, and how modern GraphQL servers implement batching under the hood. Along the way, we will look at practical execution details like field merging and batching across multiple operations. By the end, you will have a clear mental model for GraphQL batching and the trade-offs between DataLoaders, Batch Resolvers, and BFS execution. **19:00 – 19:30** **Semantic Introspection** \- Pascal Senn GraphQL's rich type system makes it an ideal foundation for agents to explore and work with APIs. The SDL provides the structure agents need to reason about capabilities and data. Queries let them retrieve information, while mutations enable them to take action. In practice, however, production GraphQL schemas are often too large to fit in the context window and difficult to understand without additional context. So what if agents could interact with any GraphQL API in a generic, reliable way? In this session, we'll look at the challenges of agentic interactions with GraphQL and how semantic introspection could unlock a new way for agents to navigate the schema and interact with GraphQL APIs more reliably. **19:30 – 20:00** **The Future of GraphQL Federation: Composite Schemas in action** \- Tobias Tengler GraphQL federation enables teams to compose multiple services into a single unified API. But the federation ecosystem is evolving. In this talk, we introduce the GraphQL Composite Schema specification, a new open standard developed under the GraphQL Foundation and co-created by Apollo, The Guild, and ChilliCream. Rather than introducing yet another competing approach, the Composite Schemas specification aims to standardize and modernize GraphQL federation by addressing limitations of earlier federation protocols. We will explore how GraphQL APIs can be federated using Composite Schemas and how queries are planned and executed across services. Along the way, we will demonstrate the first implementation of the specification with Hot Chocolate Fusion 16 and share some of the design decisions behind it. By the end, you will understand what Composite Schemas are, how they improve GraphQL federation, and how to start using them with Fusion.

**Google Analytics Alternatives** Is it finally time to make the switch away from Google Analytics? Two-and-a-half years ago Jason Packer asked this question at Columbus Web Analytics Wednesday. Since then: Google’s Universal Analytics has been sunset, we’ve changed our name to Columbus Data & Analytics Wednesday, and Jason has released two editions of his book “Google Analytics Alternatives”. Fresh off the release of the 2nd edition of his book, we thought it was time to re-open this conversation. While people love to complain about it, GA’s market share has remained relatively constant (at least in the United States). Why is that? You won’t find any complaints about GA4 in this talk, but rather an overview of what’s currently available in the market and how to frame your decision-making process. We’ll also be giving out some free copies of Jason’s book! So even if you’ve got a “GA4Lyfe” tattoo (no judgement), there’s free books to go with the free pizza and beer.
