**PyBerlin: February's event** **Sponsor**: **Sentry** **Location: W3.Hub (ground floor)** **Agenda:** 6:30 pm – Doors open: snacks, drinks, networking 6:55 pm - Welcome from PyBerlin 7:00 pm - Welcome from the sponsor - Sentry 7:10 pm – **Maximum time off, minimum leave: solving the holiday equation with Python and math // Sander Van Aken** Around the beginning of the year, German news sources publish tips on how to optimize your vacation by cleverly using Brückentage: taking a few strategic days of leave to connect weekends and public holidays into long breaks. But how can this be computed systematically? And how can it be tailored to your personal preferences? Operations Research (OR) and mathematical optimization are powerful but often underrepresented disciplines within the broader AI and analytics landscape. In this beginner-friendly talk, we treat holiday planning as a mathematical optimization problem. Using the question “How do I maximize my benefit from taking time off?”, we will walk through the full process from problem formulation to a working Python solution. Speaker's bio: Sander Van Aken is Operations Research Engineer and passionate about applying quantitative methods to solve mobility, logistics and supply chain planning challenges. Beyond his day-to-day job of developing decision support algorithms for network planning at Flix SE, he is active in the broader OR community and loves introducing people to the field. 7:40 pm - break 8:00 pm – **Exception Handling Within the Context of Python's Typing System // Jonathan Herrera** A conceptual approach to exception handling, with a special focus on Python's type hinting system. Python's typing system does not allow for annotating methods with the exceptions they raise. The talk discusses the conceptual consequences of this limitation and introduces different exception handling paradigms with their upsides and downsides. Speaker's bio: Jonathan has worked as a Senior Python Developer in different companies. Currently, he is an Engineering Manager at RoomPriceGenie, a scale-up providing revenue management solutions to hotels, where he oversees the integrations team, and works, amongst other things, on establishing best practices with regard to reliability and security. 8:30 pm – **One does not simply send a GET request // Paweł Wiszniewski** Short presentation on a few of the less-known features of the requests and urllib3 libraries. Regardless of whether you're scraping the web or extracting data from those REST API endpoints, you need a reliable and convenient way to download data from the internet. But packages get lost in the traffic, servers get overwhelmed with requests. And your job is to build a resilient data pipeline. Let's see what the most popular HTTP libraries have to offer. Speaker's bio: Paweł is a Senior Data Engineer and a founding member of the Data Platform team at Flink SE, where he builds tools and designs processes that empower data scientists, analysts, and business teams across the company. 9:10 pm - closing This event will be only in-person. Please check our Code of Conduct and official health regulation in Berlin before coming. If you feel some signs of sickness, please consider skipping this event and attending another time. We will have plenty of events in different formats in the future. Looking forward seeing you all!

Hello! I’m organising a coworking + socialising session for all of us who are working on projects (e.g. our own creations, freelance or remote work) but don't feel like sitting alone at home. 🙂 To ensure that we have time for both socialising AND working, we will be using the so-called “Pomodoro” technique: **50 mins deep work** (silent), followed by **10 mins break** to socialise. And then repeat! You are welcome to join whatever your personal background is, and whatever project you are working on. I (the host) speak English and German, so either language is fine. ——————————————————- AGENDA: * **Short Intro** Tell us who you are and share something about what you will be working on today * **Pomodoro Session** \- 3x \(3h\) Each Pomodoro session consists of 50 mins focused “deep work” (no talking, no interruptions, **phones on silent mode**) -> then 10 mins break: a chance to share your progress with others -> Repeat * **15 mins Wrap Up** Celebrate what you achieved and get to know others 😊 ———— The location is **Espresso House near Checkpoint Charlie** (they have multiple outlets - so be sure to go to the correct one!) Wifi + power plugs are available - but best to bring a fully charged laptop, just in case 🙃 You **do not** have to pay anything. But since we are using the café space, it is common courtesy to buy at least one drink (coffee costs roughly **4 Euros**).

**Uncertain Times, Adaptive Teams** What’s the next evolution of Agile? Agile turns **25 years old in 2026**. A quarter of a century after a small group of practitioners met in the late 90s to rethink how teams could work better, we once again find ourselves in a moment of profound change. AI is reshaping roles. Organizations expect clarity and measurable impact. Teams are navigating increasing complexity and shifting expectations. In many ways, it feels similar to the period just before the Agile Manifesto emerged – a time when people sensed that a new way of working was about to take shape. So the question becomes: **What could the next evolution of Agile look like?** Let’s explore it together. **What to expect** Join us for an interactive Meetup that combines a short impulse with a collaborative **World Café**. Together, we will explore several potential future scenarios of Agile and reflect on the signals, patterns, and tensions we already see in our own environments. 🧩 **World Café Session** Move through different tables, each focused on a possible future of Agile — from AI‑supported teamwork to post‑framework agility. 💡 **Fresh Insights** Exchange experiences, challenges, observations, and emerging trends from your daily work. 🤝 **Co‑Creation Instead of Keynote** This isn’t about presenting the “one right answer.” It’s about thinking together and shaping new perspectives. **Who is this for?** Anyone working with or around agility: Product Owners, Agile Coaches, Scrum Masters, leaders, transformation practitioners — or anyone curious about what might come next. **Why join?** Because 25 years after the Agile Manifesto, we may once again be standing at a moment where something new is beginning to emerge. And in this Meetup, **you can be part of that exploration.** 📅 **Date:** 19.02.2026 ⏰ **Time:** 6:15 PM 📍 **Location:** Deloitte Greenhouse, Kurfürstendamm 23, 10719 Berlin > Ground Floor > 6+7 🎤 **Hosts:** Alexander Ständert, Deloitte Consulting GmbH, Deloitte Agile Community Seats are limited. Please register through the official Deloitte event page: 👉[Deloitte | Register ](https://cloud.marketing.deloitte.de/eventRegistration?eventname=Agile%20Meetup%20Feb%2026&locale=en) We look forward to shaping the next chapter of Agile with you! #Agile #FutureOfAgile #WorldCafe #AI #Adaptiveness #25YearsAgile #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.

**✨ Women in Agile Berlin Event \| 19 February 2026 \| 18:15 ✨** **Boundaries, Negotiation, and the Hidden Cost of Saying Yes** In many workplaces, women are praised for being helpful, flexible, and always available. Much less so for protecting their time, energy, and focus. Over time, this leads to overcommitment, blurred boundaries, and quiet exhaustion. At our next Women in Agile Berlin event, we are excited to welcome Krista, a certified coach based in Berlin, who supports creatives and Highly Sensitive People in building values aligned lives. In this talk, Krista explores the powerful connection between boundaries and negotiation, and why they are two sides of the same coin. When you are clear on what matters to you and what you are protecting, you can lead, collaborate, and negotiate with calm confidence. Together, we will explore: * What boundaries really are (and what they are not) * The hidden “Yes Cost” of overcommitment and why it drains energy and focus * Why self boundaries are the first and most important negotiation * Practical, empathy based negotiation tools that help you communicate your needs without guilt or backlash You will leave with greater clarity, simple frameworks you can apply immediately, and a toolkit for negotiating in a way that feels grounded, respectful, and aligned with who you are. This event is for anyone who wants to protect their energy, strengthen their impact, and stop negotiating against themselves. 📍 TomTom Location Technology 📅 19 February 2026 ⏰ 18:15 🎤 Talk and interactive reflection, followed by community exchange We would love to see you there 💜 Women in Agile Berlin

In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA
