We make landladies and landlords. They buy a flat and pay just 1/4. 3/4 come from tax cuts and tenants. It's not a trick. It's government policy. All German Federal Governments, past and present, of whichever party, want taxpayers to become landlords and -ladies, buy property, rent it out to tenants and enjoy passive income later. Come here and find out. No strings attached. No sales. Just a meet and greet for orientation. Wir machen Vermieter. Steuerzahler kaufen eine Wohnung und zahlen dafür nur 1/4. Mieter und Finanzamt zahlen 3/4. Das ist kein Trick. Das ist Politik: Alle Bundesregierungen wollen, dass Steuerzahler Vermieter werden, Wohnungen kaufen, Mieter reinnehmen und später Beton‑Rente bekommen. Info-Abend nur zur Orientierung. Kucken kostet nichts. S,U Bahnhof Zoo, Kantstraße 163-165, 10623 Berlin, Motel One Upper West, 10th floor, turn left, circumvent the sign "vorübergehend geschlossen" Go justs there. I'll be there.

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.

**Investors Networking Meetup: Apartment Investing Knowledge** Meet other **investors** and **aspiring investors** in our upcoming meetup and discuss with us the question: How do you actually build **long-term wealth** through apartment investments in Berlin (especially, when we deal with **rent caps** and r**egulation constraints** in the real estate market)? Many aspiring investors and home buyers understand the potential of real estate, but struggle to navigate pricing, deal evaluation, financing structures, and long-term strategy in a competitive market. In this meetup, you’ll get exclusive, first-hand insights from **Achim Amann**, CEO of Black Label Properties. Working at the intersection of **high-value transactions** and **investor advisory**, Achim brings a practical perspective on what it takes to identify the right opportunities and build a sustainable real estate portfolio. Rather than theory, this session focuses on **real-world decision-making**: how to approach apartment investments, what separates strong deals from weak ones, and how to think about long-term wealth creation in today’s market environment. Join us on **May 8th at 4:00 pm** at the Black Label Villa for an afternoon of practical insights, open discussion, and high-level networking with investors, buyers, and aspiring homeowners.

🧠 **Decision-Making Under Pressure (Part 2)** The wait is over. After the great response to our first session, we’re bringing it back — with new scenarios, new challenges, and even more real-time decision-making. This is not a typical event. It’s an **interactive business simulation**, where you step into the role of a founder and face real-world startup situations under pressure. You’ll work in small teams, analyze scenarios, make decisions within limited time, and present your approach — just like in real life. *** # 💡 What to Expect 🔹 Work in teams 🔹 Solve realistic startup scenarios 🔹 Make decisions under time pressure 🔹 Present your strategy 🔹 Receive feedback and different perspectives Each round becomes more challenging, pushing you to think faster, communicate clearly, and act with confidence. *** # 🎯 Why Join Because building a startup is a series of decisions — and the ability to make them under pressure is what makes the difference. Whether you’re a founder, aspiring entrepreneur, or simply curious, this session will challenge you to think critically and act decisively. *** # 📅 Event Details 📅 **May 9, 2026** ⏰ **17:00 – 19:00** 📍 **MAATI – Indische Küche** 🤝 Community We’re building a space where people don’t just network, they **connect, collaborate, and grow together.** For updates about upcoming events, networking opportunities, and founder meetups, join our **WhatsApp community** where entrepreneurs support, connect, and grow together. 👇 [https://chat.whatsapp.com/IOjguBGBakz59qp2b6BE0V](https://chat.whatsapp.com/IOjguBGBakz59qp2b6BE0V)

Welcome to Sunday Tech Coffee. This is a **networking** event for those in the tech industry in Berlin. We are usually inside and to the right. Ask the barista/bartender if you can't find us.

Join us for a hands-on, collaborative **4-hour workshop** where we use LLMs to code. We will be implementing the following 3 exercises: [connect four](https://www.hellointerview.com/learn/low-level-design/problem-breakdowns/connect-four) [amazon locker](https://www.hellointerview.com/learn/low-level-design/problem-breakdowns/amazon-locker) and [elevator](https://www.hellointerview.com/learn/low-level-design/problem-breakdowns/elevator) ### **What we will do** We will use the LLM (any free one, like chatGPT) to write code that solves a given problem. Our goal is to not write code by hand, and to produce an application that passes a set of specifications. ### 🛠 **Share ideas about agentic coding** We will be practicing our agentic coding skills: * bring a laptop with Java or Golang installed * know how to code in either Java or Golang * share and explore ideas about how to use LLMs to create production-ready applications ### 💬 **Atmosphere & Logistics** The workshop is **free**. There will also be a 20 min pause, if you want to order snacks.

At this meetup, we are going to break down how to reverse engineer direct-to-seller marketing using our SCALE framework so you can approach your marketing with more clarity, confidence, and consistency. We will cover how to think through inbound, outbound, and free marketing channels, how to choose the right channel for your goals, how to run the numbers before you spend, how to allocate the right budget, how to launch the campaign correctly, and how to evaluate and track performance so you can make better decisions moving forward. **SCALE Framework:** **S –** Select the right channel **C –** Calculate the numbers **A –** Allocate the budget **L –** Launch the campaign **E –** Evaluate and track it **What We’ll Cover** * How to get off-market deals through direct-to-seller marketing * How to stop guessing and start reverse engineering your marketing * The difference between inbound, outbound, and free marketing channels * How to choose the right channel for your business and market * How to calculate the numbers before launching * How to allocate a budget based on goals, not emotion * How to launch and track a campaign the right way * How to create more consistent and predictable deal flow **Date:** May 28, 2026 (Thursday) **Time:** 6 - 8pm EST **Location:** Ohio Brewing Company, 421 E 2nd Ave, Columbus, OH 43201 **Save Your Seat** → https://www.eventbrite.com/e/how-to-get-off-market-deals-with-direct-to-seller-marketing-tickets-1987845260686?aff=cicmeetupapp **FREE DRINKS & FOOD PROVIDED!** **About Columbus Investors Club** The Columbus Investors Club is a local meetup for real estate investors, aspiring investors, contractors, vendors, lenders, realtors, and other professionals who want to grow in the Columbus market.

**Total Eclipse of the Chart: School Redistricting Dashboards** In this presentation, we will explore the utilization of maps, sets, and SQL within a Tableau dashboard to help provide “what-if” analyses generated through the use of a mapped dashboard, providing different scenarios and the potential implications of these. While in this use case we are focused on a large school district, the concepts of utilizing existing data to explore the future impacts of modifying different geographic boundaries can be useful to many industries, balancing the mix of maps with visual analytics. **About Our Speaker** Robert Kramer is the Data Systems and State Reporting Coordinator at South Western City Schools in Grove City.
