Web Zurich presents inspiring talks all about the web. Join us for the March 2026 meetup! We will have three talks as well as chit-chat and drinks. Whatapp: [https://chat.whatsapp.com/FxOfVTK9nf431xHtVl3eGK](https://chat.whatsapp.com/FxOfVTK9nf431xHtVl3eGK) Website: [https://webzurich.ch](https://webzurich.ch) 18:30 \~ 19:00 Arrival time with drinks, chat and introduction 19:00 \~ 19:40 *Christian Heitzmann* **Why Documentation Won’t Write Itself—and AI Won’t Save You** For the last 15+ years, I’ve joined and consulted software teams that all struggled with the same problem: nobody likes writing documentation, and everybody pays the price for it. New developers spend weeks reverse-engineering codebases, architecture lives in people’s heads, and wikis quietly decay into noise. With AI now entering the picture, many hope it will fill the gaps. It won’t. I’ll show the simple ideas that change everything: how to think about documentation in the right levels, how to keep it close to the code, and how to avoid the decay we all know too well. These are the decisions that have to be made before any tool or process can work. The documentation won’t write itself. But there are ways to make it far easier and far more reliable. 19:40 \~ 19:50 **Short Break** 19:50 \~ 20:10 *Marco Gähler* **How to write good code** There is an infinite amount of solutions how you can solve a programming problem. Some are better, others are worse. The best solutions are easy to understand, maintain and errors are not able to hide. I wrote a book "Software Engineering Made Easy" about this topic and I'm more than happy to explain some principles that make your code better. Most of them are quite simple to understand, once you understand the mechanics, why your code always breaks. 20:10 \~ 20:30 *Marius Ishida* **AI: The Lightsaber Problem** My talk will challenge the popular narrative that AI fundamentally democratizes power by showing that, which I believe is not true at all. While generative AI lowers entry barriers for basic tasks, it disproportionately amplifies the productivity and leverage of already computer literate users. Empirical research shows that AI acts as a skill multiplier rather than a true equalizer, with outcomes strongly dependent on users’ ability to frame problems, verify outputs, and integrate tools into complex workflows. As a result, AI risks reinforcing a new AI driven digital divide, where technical literacy—not access alone—determines who truly benefits. 20:30 onward More drinks & chat We look forward to see you there!

**New Dojo Location!** **Draft Day Columbus** 1130 Dublin Road Columbus, OH 43215 We're going to try a new dojo location for a few weeks and see how it works Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead. We're looking for topic suggestions and people interested in presenting at our monthly meetings. To this end we've set up a survey form at [https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc](https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc)

**First meetup of the Columbus AI Engineering group.** We’ll kick things off with a practical, beginner-friendly discussion on: **How LLMs like ChatGPT actually work — and how to build real applications with them.** We’ll cover: * what’s actually happening under the hood (at a high level) * why LLMs behave the way they do (hallucinations, prompt sensitivity, etc.) * how people are building real systems with them today * where things break in practice This will be a **short, informal talk (\~15–20 min)** followed by open discussion and Q&A. Whether you’re an engineer, builder, or just curious about how modern AI systems work, you’re welcome to join. No slides, no fluff — just real conversation about real systems. We’ll hang out afterward and get to know each other.

The Unix philosophy emphasizes simplicity, modularity, and the idea that programs should do one thing well and work together. However, CLI programs are primarily used by humans. Programs that you actually enjoy using can achieve both of these aims of composability and human-centeredness. This talk explores what makes CLIs great: fast, trusted, and delightful. Through real-world examples from modern tools like uv, cargo, ripgrep, and GitHub CLI, you'll learn the design patterns that separate good CLIs from great ones. Whether you're building package managers, creating developer tools, or just curious why modern CLIs feel so much better, you'll leave with a practical checklist of techniques to apply to any CLI tool you build. **Agenda:** 7:00pm - Opening announcements 7:10pm - Opening Topic - Build an AI-powered, Sassy Speaking Plant 7:25pm - Main Topic - Designing Delightful CLIs with Python 7:50pm - Q&A

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.
