Join us for the first meetup in 2026! ⭐️ Are you interested in the Ruby language or Ruby on Rails? Join us. We have great talks, good vibes, and yummy snacks! 😋 **Talks** \~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~\~ 🗣️ [Peter Solnica](https://solnic.dev/) ▶️ Structured Logging in Ruby: Where We Are and Where We're Heading 🗒️ Ruby's logging ecosystem is evolving, and there's a lot of momentum to build on. In this talk, we'll explore the current state of logging in Ruby and compare it with ecosystems like Elixir, where a more capable, well-designed logger is built right into the standard library. We'll dive into recent developments in Rails - including its new structured events API - and how they connect to the broader picture of structured logging, error handling, and tracing. Along the way, we'll build a vision for what Ruby's standard library could offer: a powerful, extendable logger that makes structured logging a natural part of every Ruby project. 🗣️ [Marie-Therese Fischer ](https://fischer.codes/) ▶️ Building Games with Ruby 🗒️ What do you end up with when you strip Rails from a Rails developer? Plain Ruby. Join me as I explore the language behind the framework through the lens of game development. By building a simple terminal game and a 2D platformer, I’ll break down the essential building blocks every game is built on - from loops and input handling to visuals. We'll look at how stepping away from the 'magic' of Rails to build games can lead to a deeper understanding of Ruby logic and application structure. 🗣️ [Christoph Lipautz](https://github.com/unused) ▶️ The Art of Testing Nothing 🗒️ Traditional CI/CD pipelines often waste significant resources re-validating unchanged code, creating a bottleneck in the development lifecycle. This session explores the results of my attempts to shift from exhaustive execution to smart omission. I'll discuss how doing nothing turns into a technical strategic advantage while maintaining confidence. **Location** **\~\~\~\~\~\~\~\~** Mariahilfer Str. 97/4, 1060 Wien **Sponsors** \~\~\~\~\~\~\~\~\~ ⭐ [Meister](https://www.meisterlabs.com/jobs/) Founded in 2006 by Till Vollmer and Michael Hollauf, Meister’s journey from start-up to scale-up has been a story of continual growth. What started with a vision to create a simple visual mind-mapping tool has become not one but two collaborative tools that help teams everywhere focus on the work that matters.

We are happy to announce the next [eBPF](https://ebpf.io/)-focused meetup in Vienna scheduled for March 6, 2026. All talks will be suited for beginners and experts as well. Whether you're a web developer, platform engineer, data scientist or simply curious about the latest advancements in the world of IT, this event is for you. Come and join us to network with like-minded professionals, expand your knowledge in eBPF and explore how this open-source technology is revolutionizing the way we solve problems. Don't miss out on this opportunity to stay ahead of the curve! *Special thanks to our sponsors:* *\- ÖBB for providing an excellent venue for this meetup\!* **Agenda:** * 17:00 - 17:25: Arrival and Registration * 17:25 - 17:30: **Welcome** - *by the Organizers* * 17:30 - 18:00: **The pod knows where you're from** *\- preserving Source IP with Cilium and DSR* \- by Marcel Gredler * 18:00 - 18:30: Break * 18:30 - 19:00: **Signing eBPF for Security** *(with Hornet LSM)* \- by Julian Zhuang * 19:00 - 21:00: Closing Words & Networking Apero **Topic 1: The Pod Knows Where You're From – Preserving Source IP with Cilium and DSR** In this session, Marcel Gredler delves into maintaining original source IP addresses in Kubernetes pods using Cilium and Direct Server Return (DSR).

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.
