The common wisdom goes: data is either transactional or analytical, and workloads are OLTP and OLAP-shaped to match. The reality of generating and using data is different, and often we need a bit of both. The pg_lake extension brings OLAP workloads to OLTP Postgres. This talk will explore the pg_lake extension, including how to build it, and demos of using it with modern data workloads in object storage like Amazon S3. We’ll create simple data pipelines with no ETL and high performance analytics. **I Didn't Know Postgres Could Do That!** by Robert Treat, Principal Database Engineer at AWS and PostgreSQL Major Contributor. PostgreSQL is often thought of as "The Database for DBAs", but what more and more developers are finding out is that what makes Postgres "The Worlds Most Advanced Open Source Database" is its wide array of features, many of which are really geared towards engineers building applications on top of Postgres. In this talk, we'll look at some of the features in Postgres you may not have seen in other database systems, and talk about how you can make use of those features in your applications. Queries, indexing, data types, and more will all be up for discussion as we show you examples of just what Postgres can do.

Agenda * 19:00 Welcome to the PUB (Python Users Berlin) – setting up * 19:15 Impressions from PyCon DE and PyData Darmstadt * 19:45 Workshop on adapting to LLMs as Python Programmers * 20:45 Social gathering (hang out afterwards to chat) This month host Travis will be presenting on his key takeaways from the recent PyCon DE & PyData Darmstadt, including personal highlights from the conference and which talks you should watch later on YouTube.

**Join us for outdoor grass volleyball in Hasenheide park!** This event is not suitable for complete beginners. We play with two nets. The "chill court" is for mixed-level play with 3v3 up to 5v5. The "competitive court" is for higher-level 2v2 play with beach rules. Be sure to wear suitable sports clothing and perhaps bring a drink. There are no facilities such as changing rooms and showers in the park. A nearby public toilet is also available, but it might be closed, dirty, or not have toilet paper. **Location**: We play in the narrow clearing, located between the two paths in the center of Hasenheide park, on the southern side.

The Language Café is primarily aimed at people who are struggling with their mental health which can make it hard to go to regular courses. We want to create a safe space for everyone to learn and practise without pressure. Everyone is welcome! Please try to be on time so we can all get started together :) We mainly practise on a beginner/lower intermediate level and adapt to everyone's prior level of German. The Language Café will focus on teaching you the most important words and phrases and basic grammar in German. The content of the course is adapted to real life. (everyday life in Germany, dealing with authorities, etc.) We will cover different topics every week and you can join us anytime, since the topics do not necessarily build on each other. The Sprachcafé is for free. \*If you cannot make it please cancel your participation so someone else from the waiting list can join, thank you!\* \| \| \| \|

Join us for a practical, beginner-friendly guide to choosing the right large language model. We’ll compare major models like ChatGPT, Claude, Gemini, and Llama, talk about when to use hosted APIs versus local models, and break down the tradeoffs around cost, speed, quality, privacy, context windows, coding ability, and reliability. You’ll leave with a clearer mental model for picking an LLM based on your actual use case instead of hype, benchmarks, or brand names. No deep AI background required. 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!

Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.

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!
