📆 Agenda * 19:00 Welcome to the PUB (Python Users Berlin) – setting up * 19:15 Main talk * 20:00 Lightning talks * 20:30 Social gathering 🎙 Main talk by [Sam Bail](https://www.meetup.com/de-DE/members/57634242/): PySpark PySpark is a powerful library that brings Apache Spark’s distributed computing capabilities to Python, making it a key tool for processing large-scale data efficiently. In this talk, data engineer and analyst Sam Bail provides a structured and hands-on introduction to PySpark, starting with an overview of Apache Spark, its architecture, and its ecosystem, such as Databricks. Learn about Spark’s core concepts, such as the DataFrame API, transformations, lazy evaluations, and actions, before setting up a lab environment and working with a real dataset. Plus, gain insights into how PySpark fits into a broader data engineering ecosystem and best practices on running PySpark in a production environment. 👩‍💻 About [Sam Bail](https://www.meetup.com/de-DE/members/57634242/) Data engineer and engineering leader with 10+ years building platforms and teams across healthcare, marketplaces, and data infrastructure at NYC tech startups.

Most brands track whether they appear in ChatGPT, Gemini, and AI Overviews. But mentions and citations only tell half the story. In this session, Raoul Schreck, our CEO at Buzzmatic will show you how to systematically analyze what AI actually says about your brand: which attributes it assigns to you, which USPs it credits to your competitors, and where your communicative blind spots are. Using a real client case and a concrete 4-layer framework, you’ll learn how to move beyond visibility tracking and uncover the narratives AI systems are building around your brand — and what to do about them the next morning. Book your ticket now to secure your spot at the Rise & Rank SEO and AI breakfast!

This talk walks through a practical demo of automating the full SRE lifecycle: from incident investigation to deployment validation, using Grafana MCP and the GitLab Agent Platform, and where humans still need to stay in the loop. *Serhii Vasylenko* **The Pipeline Was Green — AI Agents and CI Trust** We’ve spent years building CI/CD pipelines that tell us when code is "technically correct," but are they capable of telling an autonomous AI agent if a change is safe to apply? This talk explores a real-world incident where an AI-powered automation -- pairing Renovate with Claude Code -- successfully executed a "green" pipeline that broke a critical QA cluster for three days, how the team reacted, and how we evolved our vision toward the future of human-agentic collaboration with code. *Frithjof Hoffmann* **Managing Uninvited Guests: Securing Open Source Dependencies** Open source software is the ultimate neighborhood party, but what happens when an uninvited guest slips through the door? This talk digs into the messy reality of dependency hell and its role in software supply chain security: from typosquatting attacks to maintainer account takeovers, and the abandoned projects with known CVEs quietly living in your codebase rent-free.

This will be the first meetup of the group. A relaxed evening for people interested in bug bounty hunting, web security, AppSec and vulnerability research. The main goal is to meet like-minded people, talk about bugs, tools, targets, methodology, reports, interesting findings and whatever else comes up around security research. Since it is the first event, we can also spend a bit of time discussing how future meetups should be structured: casual chats, hacking sessions, short talks, tool sharing, report discussions or presentations. As soon as at least **3 people join**, I will look for a suitable location. The first meetup will probably be in a **café, bar or restaurant**. If there is enough interest in presentations, I can also look into booking a room with a **TV or projector** for future events. No preparation needed. Please keep everything legal and authorized.

Highlights and Hidden Gems in SQL Server 2025 With so much emphasis on cloud data platforms and AI these days, SQL people can feel left behind by all the marketing hype. SQL Server 2025 was officially released in November of 2025, though, and contains a ton of improvements that will make our SQL Server deployments a bit faster, better, and more secure. There are even more improvements tucked into the release that never made a marketing blog or press release that you'll likely be learning about for the first time in this session! Join this session to learn about what makes your high availability a little more available, your performance a bit more performant, and your database more developer and app-friendly. Come spend an hour with SQL people talking SQL Server 2025 – the good, the "not quite ready for prime time", and the hidden awesomeness.

**Practical Curiosity: Learning from Everyday Data** How do we actually get better at utilizing our day-to-day data? Fancy dashboards and complex models might look nice and draw attention, but that’s not where most of us spend our time. In fact those shiny outputs frequently sit unused, while the real insights are drawn from the analyst’s daily practice. Sometimes it’s as simple and as powerful as noticing that a segment is shrinking, a channel is underused, or certain links keep getting all the clicks. There’s many different places that the spark of insight can come from, but you have to keep your head in the data and know where to look. In this session, we’ll explore real-world examples of how segmentation, testing, and click behavior can uncover practical digital marketing opportunities. You’ll leave with inspiration for your own use cases, along with a few simple ways to ask better questions, spot meaningful patterns, and make smarter decisions without overcomplicating it. **About Our Speaker:** [Elaine Armbruster](https://www.linkedin.com/in/elainearmbruster/) is a Director of Digital Experience at the [American Diabetes Association](https://diabetes.org/), where she focuses on using data and insights to create smarter, more effective digital experiences. A lifelong Columbus resident, she has built her career in email marketing and the broader digital user journey, and is finding she most enjoys working in the messy middle where systems, data, and big ideas don’t quite line up yet.

You can sleep in on the Sesquicentennial (observed), we’re shifting to the following Friday. But join the local UX community for a chat and some biscuits to catch up.

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
