📆 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.

Join us for the **Berlin DevOps Summer Meetup**: our last edition before the summer break! We're excited to be hosted by **Parloa** for an evening of interesting talks, discussions, and networking. There will be food and drinks provided, and plenty of time to connect with fellow DevOps enthusiasts. **📌 Please register at least 24 hours before the event.** We need to share the attendee list with the Parloa office in advance, and **spots are limited**. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **Agenda** 18:30 Open Doors, Networking with Food and Drinks 19:00 Welcome words by Parloa and BLN DevOps team 19:25 **Running K8s with AI: Automating** **the SRE Lifecycle with Grafana MCP and GitLab** 19:50 **The Pipeline Was Green — AI Agents and CI Trust** 20:15 Short Break 20:30 **Managing Uninvited Guests: Securing Open Source Dependencies** 20:55 Networking 21:30 Closing ➡️ Interested in hosting an event?

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 is a 3 phase meetup. You can come at any time. 1.) 6:30 - 7:00 p.m.: Gathering at the meeting spot (see link and photo!). 2.) 7:00 - 7:30 p.m.: Walk & Talk through Tiergarten. 3.) 7:30 - 10:00 p.m.: Immerse conversations in the Zollpackhof beer garden (reserved tables for the meetup). **1.) Meeting spot is Henriette Herz Park.** Copy the coordinates into your maps app: **52°30'38.9"N 13°22'24.1"E** The exact meeting spot can also be seen in the photo. Look for a meetup sign or organizer wearing a black or red lanyard with "staff" written on it. **Best ways to get there:** 1\. S\-Bahn: Get off at Potsdamer Platz by S1, S2 or S25 and walk to the designated meeting spot. 2\. U\-Bahn \(subway\): Alternatively you can get off at Potsdamer Platz by U2 and just walk 5 min straight to the park. 3\. Bus: If you change at mainstation you can take the M41 or M85 to S Potsdamer Platz /Voßstr. and walk to the park. **2.) Walk & Talk through Tiergarten** (the best part imho). During these weird times it essential to connect with nature and like minded people. You will feel instantly energized and an inner calmness afterwards. **3.) How to the find the Zollpackhof beer garden:** https://goo.gl/maps/vDYYaJcFvTmd7hei7 Elisabeth-Abegg-Straße 1, 10557 Berlin We will be sitting outside. Click the gmaps link with the exact meeting spot if you can can't find us! If you enter from the Magnus-Hirschfeld-Ufer, just go to the left part of the beer garden where the self-service is. If you enter from Elisabeth-Abegg-Str, enter the beer garden from the right. *Who is this meetup for:* 1\. Internationals who want to practice German or any other language\. 2\. Germans who want to improve their language skills\. 3\. Anyone who is interested in cultural exchange and wants to socialize\. *What you can expect:* 1\. A professionally organized meetup that can adapt to any changes given the current situation\. 2\. A Walk & Talk to break the ice\. 3\. A collaborating venue where you can further socialize with other members\. *important:* This event is at the same time and meeting location like the "Asian Languages & Culture Exchange 日本語, 한국어, 汉语" one. So I'm basically organizing 2 events at the same time which means that you can expect way more people than on the list. *** Whenever you attend a meetup, the most common as well as first question you get is: "Where are you from?" You probably heard this question a million times. Well, at least I did. From my own experience of attending over 200 international meetups in various countries such as Germany, Japan, Australia and Thailand, I can tell you that asking for the name is a better approach. “A person’s name is to that person, the sweetest, most important sound in any language.” - Dale Carnegie If you really want to connect with like-minded people you should remember their name, but you don't have to remember every persons name you've talked you. Be picky about that, don't be me who can somehow remember everyones name easily. Don't tell yourself sth. like "I'm bad at remembering names." It's all about developing the habit of asking for a name and keep the conversation going on. Furthermore, you want to learn German or any other language. Learning the local language is crucial to connect with the locals and developing a true friendship. This can be accomplished with immersion. My goal is to inspire you to go out of your comfort zone and improve yourself each time you join this meetup.

Join us for intermediate and advanced play on outdoor 2v2 courts. If you are not yet at the intermediate level (F1+) or want to play 3v3/4v4, sign up via [the simultaneous event](https://www.meetup.com/berlin-volley/events/) instead. We play with beach rules: do not use open hands for the first or last touches, do not touch the net, etc. We overbook slightly to ensure we have enough players and to allow individuals to take breaks. After playing, you can join us for socials with drinks and snacks at the bar area. It's recommended that you come 10 minutes early so you have time to change and find the fields.

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.

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. If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why I’d even want to. Thanks to the team at Nationwide of supporting the group.

We meet to learn and practice American Sign Language and to grow our familiarity with Deaf culture. Facilitated by hearing folks (with a connection to a professional interpreter) using Deaf-created content. People of all ASL skill levels are welcome! As we learn, we hope to connect more with the Deaf community in Central Ohio. Join us as you're able! Come regularly or just once - whatever you're looking for! Each meetup will explore different topics related to ASL/Deaf culture, and will feature time to practice conversation with one another. Just bring yourself and a willingness to learn!
