Join us for a hands-on workshop by Olena Kutsenko on Wednesday, February 25th from 5:30pm hosted by SPACE SHACK Coworking! **Venue:** **SPACE SHACK Coworking** Akazienstraße 3A, 10823 Berlin, Germany **Agenda:** * 5:30pm – 6:00pm: Welcome, Food/Drinks & Networking * 6:00pm - 8:30 pm: Workshop by Olena ** So that Olena has an idea of audience priorities, please fill in the [pre-workshop form](https://docs.google.com/forms/d/e/1FAIpQLSeJsBjgkL2EXvPtBScXtI5yAv6N9gFg64QmMajMUiMmaPllxQ/viewform?usp=sharing&ouid=117948459316244235775) when you can (no personal info is collected)** ** Speaker & Workshop Details:** Olena Kutsenko, Staff Developer Advocate, Confluent **Hands-on workshop: real-time flight data streaming, anomalies, predictions, and visualizations** **Workshop Overview** In this hands-on session, we'll build a real-time analytics pipeline using flight data and modern streaming tools — step by step, and without hand-waving. We'll start by streaming data into Apache Kafka using Confluent Cloud, process it with Apache Flink, and land it in Apache Iceberg using Tableflow. From there, we'll query the data with Trino and turn it into dashboards using Superset. Everything runs in a practical setup you can reproduce later, including Docker and cloud-managed services. Along the way, we'll also look at anomaly detection and simple predictions using built-in functions, so you can see how real-time insights can be added without building custom ML pipelines or complex models. This session is all about doing, not slides. You'll see how the pieces actually fit together, what decisions matter in practice (regions, credentials, formats), and how to go from streaming data to analytics in a way that scales. If you're curious about real-time analytics, Kafka + Flink in the cloud, or how streaming, analytics, and lightweight predictive use cases come together in the same pipeline, this workshop will give you a clear, working mental model — and code you can take home. No prior experience with Kafka, Flink, or Iceberg required! Just bring your curiosity and a laptop! **Technical Prerequisites:** To make sure you can get hands on during this workshop, please make sure the following are installed on your system (**Make sure your bring your laptops!)** **1\.

Let's talk Android! This month, we are at SumUp and are welcoming these amazing opportunities: **Android AI Workflows** - *Frank Tamre* I will share a practical, what i sue set of AI workflows I use in Android projects to ship faster without sacrificing code quality. This isn’t a “prompt engineering” talk; It’s a set of repeatable patterns that can integrate into Android engineering. **Crafting Idiomatic APIs with Kotlin and Compose** - *Ash Davies* In this talk, we’ll dive into the principles of idiomatic Kotlin and explore how they apply to designing Compose APIs. You’ll learn how to leverage Kotlin’s language features, from DSLs and inline functions to advanced type safety and composable conventions, to craft APIs that are a joy to use. By mastering these techniques, you can deliver APIs that not only “work” but truly feel like Kotlin. **Your Talk here** - *You* *{Insert your talk topic here}* Afterwards, we welcome you to stay and socialize (or sit in the corner listening) with or against our community. Happy Coding / Prompting / Designing / Leading / Working.

Hello fellow Symfonians, we are thrilled to announce the first user group meeting of the year, featuring two insightful talks that you **won't want to miss**! This time we are hosted by c-base (Rungestrasse 20 10179 Berlin). Come by and enjoy an evening of learning, networking, and socializing with fellow Symfony and PHP developers. **Agenda:** 18:30: Doors open 19:00: Welcome and Introduction 19:20: **Talk 1: "Agentic coding with OpenCode" by Damijan Cavar** 19:50: Break & Snack 20:00: **Talk 2: "Composer Deep Dive" by Nils Adermann** 20:40: Socializing **Talk Details:** **Talk 1: "Agentic coding with Opencode" by Damijan Cavar** Summary (ChatGPT generated): AI coding assistants are evolving beyond “vibe coding” toward **agentic, spec-driven development**. This talk explores why prompt-based workflows break down at scale and how structured specifications create a reliable foundation for autonomous coding agents. You’ll see how **OpenCode**, an open-source, model-agnostic coding agent, uses planners, implementers, and reviewers to turn specs into verifiable code while keeping context small and repeatable. The session also covers practical security considerations, sandboxing strategies, and real-world lessons from using agents on non-trivial projects. **Talk 2: "Composer Deep Dive" by Nils Adermann** This talk will take the audience on a deep dive into Composer. We'll start on the surface with the big picture of Composer (how exactly do require/update/install relate to json/lock/vendor), followed by commands and arguments not widely known and used (e.g. bump, why/why-not, update options like --with-all-dependencies, --minimal-changes, and --ignore-platform-req=php+ and what exactly the plus means). We'll then advance to the underlying concepts like the platform repository, security concepts around Composer plugins and answer questions like "Why is there a hash in the lock file and how to resolve conflicts?", or "Why do repositories need to be defined on the root composer.‎ json?" and finally reach into dependency resolution with a quick explainer on how Composer uses a SAT solver and boolean algebra to decide which packages to install. Back above water, the talk will end with an outlook on changes we're planning for Composer and [packagist.org](http://packagist.org) in the future. Don't miss these insightful talks, engaging discussions, and networking opportunities. We can't wait to see you at the **February Symfony User Group**!" If you have any questions or accessibility requirements, please reach out to us. Also, if your company wants to be the next host for the User Group, just let us know!

In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA

**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.
