Mixed Friendly Football @ Sportpark - Lousy & Lazy

Do you like to play football - but relaxed and not with competitive or aggressive players? Are you a bit lazy, a bit old, a bit unfit or not so talented? Then Lousy & Lazy Football is the right thing for you! We are a group of friendly people who just want to have a relaxed kick. All genders, ages (+18) and nationalities welcome. Feel free to join the waitlist even if it seems long - sometimes we make the event larger and play on two pitches (24 players, four teams) or even three pitches (36 players, six teams), depending on demand. Note: We do not allow high-studded football boots during our sessions. To avoid injuries, we only play with "Multinocken" (multistuds) or shorter. Please have a look here: [link](https://www.11teamsports.com/de-de/fussballschuhe/multinocken/). Lousy & Lazy rules: 1. **Don’t be competitive - fun only! Enjoy the workout, nice people, wonderful weather and magic ball moments** 2. **No emotional shouting, no telling other players where to go and what to do** 3. **No hard tackling/sliding** 4. **Avoid injuring yourself and other players at all costs: Tight situation? Give up the ball rather them going all in** 5. **Support less fit and less skilled players by giving them the time and space to play the ball, don't intercept passes to and from them. Bonus points: Make them shine!** 6. **Don’t dribble past multiple players (trying to take on one player is fine)** 7. **Don’t close down the defenders too quickly. Give the team a chance to play the ball out.** 8. **Rotate the goalkeeper** 9. **Be a teamplayer** 10. **Come regularly and be reliable with your RSVPs**

🏓Pongmasters Open @Sektgarten🥳

Portrait Drawing on Sunday Afternoon

This group is for everyone who is interested in drawing portraits! For me, drawing has been a wonderful way to gain a new perspective on the world and the people within it. Whether you are just starting out or have been drawing for ages — all levels are welcome :) How it works: 1\. We meet at The Castle pub in Mitte and do short sittings of 15 minutes for each other\. The first sitting is divided into 3 warm\-up sketches\, 5 minutes each\. 2\. Before we start\, everybody writes their name on a blank card \(provided by the organizer\); these cards are then used to randomly pick the model every 15 minutes\. 3\. Usually we do 8 sittings\, with a 15\-minute break in the middle \(so after 4 sittings\, or 1 hour\)\. -> The participation is free, but it is expected that everybody orders something from the bar to support the lovely location. Get out your pencils and let's start! Please bring your own art supplies!

Quality Engineering meetup #13

**PLEASE NOTE THE ADDRESS CHANGE! We're now at DEUTSCHE BANK BERLIN!** *In collaboration with* *Deutsche Bank*, *[Qase](https://qase.io) is presenting the **thirteenth** Meetup on Quality Engineering in Berlin.* *We’re bringing you three deep-dive talks: all designed to challenge the way you think about quality, testing, and collaboration.* *As always, expect great conversations, snacks, and drinks. See you there!* **AGENDA** **1\. Olga Bokova @ Deutsche Bank:** ***Testing the Nanoseconds: A Decade of High-Frequency Trading QA Evolution*** High-frequency trading systems operate at the edge of technology, where latency is measured in nanoseconds and every delay can translate directly into financial impact. In this environment, traditional QA approaches quickly break down, e.g. functional correctness alone is no longer enough. In this talk, Olga will share a real-world journey of how QA evolved over the past decade within high-performance trading systems. We’ll explore the challenges of testing ultra-low latency platforms, handling massive market data streams, and ensuring deterministic behaviour in highly distributed environments. Olga will walk us through how fragmented testing approaches led to inefficiency, duplication, and scalability issues, and how they transitioned toward a unified, domain-level testing framework built around simulation and controlled environments. You’ll learn how treating testing infrastructure as an engineering product helped us reduce complexity, increase reliability, and enable performance testing at realistic market scale. Along the way, Olga will share practical lessons, trade-offs, and what they chose to abandon (not just what we built). **2\. Neha\-B Yadav @ Deutsche Bank: *Secure AI, Smarter Testing: How QA Teams Can Shift Left Efficiently*** Now as ever, staying effective and efficient requires more than just strong testing fundamentals, but also intelligent orchestration of tools, data, and automation. Neha will focus in this talk on three key dimensions: how to stay effective with the help of AI-driven test workflows, how to remain relevant with modern engineering practices and enterprise tooling, and how to continuously upskill in an ecosystem of automation, AI agents, and integrated test platforms. Neha will share her approach with shifting testing left, proactive defect prevention, early test design, and proper continuous integration. The session will highlight techniques such as test-driven development, early collaboration between QA and engineering, and integrating validation into CI/CD pipelines to reduce downstream risks. **3\. Vitaly Sharovatov @ Qase: Leading Cost\-Cutting Initiatives by Improving Quality** More and more companies are cutting costs and doing layoffs, and QA is often among the first to be cut. Yet it is precisely QA folks who can help cut costs while improving quality. In this talk, Vitaly suggests ways we all can lead cost cutting discussions to make things right and either reduce or prevent layoffs. Partner with Customer Support to identify which escaped defects cost the most in ticket handling and escalations. Partner with Sales to identify which bugs put renewals and expansions at risk. Add Finance for SLA credits and refunds, and Engineering for incident response and hotfix effort. Add it all up, and you get external failure costs. After that, quantify internal failure costs like rework, retesting, queues, and waste. We will turn these numbers into a cost cutting proposal that managers understand: reduce the priciest external failure costs first, then reduce internal failure costs, by improving the way we build quality in. You will leave with a simple template for collecting the numbers with other departments, doing the calculations, and proposing specific process changes. Let's be the people who cut failure costs, not the people who get cut!

Sunday Tech Coffee Meetup

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.

BitDevs Bitcoin Socratic Seminar Berlin

**BitDevs Bitcoin Socratic Seminar Berlin @ c-base Raumstation** Join us for our monthly interactive **[Bitcoin Socratic Seminar](https://bitdevs.berlin)** in Berlin! We’ll start with pizza and beer (sponsored by [Ordimint.com](https://ordimint.com)), followed by deep-dive discussions on the most interesting *technical* developments in Bitcoin from the past month. Participation by everyone is highly encouraged! Our goal is to foster lively discussion, knowledge sharing, and debate. In the weeks leading up to the event, participants gather topics such as: * New research papers * New BIPs and BOLTs * Network statistics * Technical blog posts * Mailing list and Delving Bitcoin threads * Pull requests and updates from key repos (Bitcoin Core, LND, Core Lightning, Eclair, BDK, rust-bitcoin, LDK, Electrum, …) Each topic is briefly introduced by our moderators and then discussed before moving on. The full list of links will be published at [bitdevs.berlin](https://bitdevs.berlin) 1–2 days before the event — please review them in advance to get the most out of the discussion. **Important details:** * This event is highly technical — best suited for those with a solid grasp of Bitcoin internals. Curious newcomers are always very welcome, but expect in-depth conversations (see the former topics at [bitdevs.berlin](https://bitdevs.berlin)). * Chatham House Rule applies: you may share what was discussed, but not who said it. No livestream, no photos, no recordings. * The evening begins with food and networking; people often stay after the seminar to keep talking. **Co-hosted by:** * [Felix](https://x.com/FelixWeis) * [Freerk](https://x.com/freerko) * [Fabian](https://x.com/fjahr) For background on the idea of BitDevs Socratic Seminars, see [this article](https://bitcoinmagazine.com/articles/op-ed-want-to-learn-about-bitcoin-try-a-local-socratic-seminar).
