**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

Join us for the next Spring User Group Berlin meetup! This time, we are bridging the gap between rock-solid operations and developer joy. **Talk 1: Secure and Seamless: Injecting Kubernetes Secrets into Spring Applications** *Speaker: Dmitriy Goi, Deutsche Bank* Look, we’ve all done it. You need a database password, so you throw it into an environment variable and call it a day. It works, it’s fast, and your app starts up. But then the security audit hits, or your credentials rotate and suddenly your logs are full of connection errors because your Spring context is stuck in the past. At Deutsche Bank, "good enough" usually isn't. I’ve spent the last few years moving Spring apps into Kubernetes and realizing that most tutorials lie to you. They show you the easy way, not the way that survives in production. I’m going to show you why environment variables are a security trap and how mounting secrets as files actually works (and where it breaks). We’ll get into the mess of secret rotation, why you probably need a CSI driver or an External Secret operator, and how to make Spring Boot actually pick up those changes without a manual restart. **About the speaker:** A passionate software engineer at Deutsche Bank, Dmitriy brings 8 years of development experience to his focus on modernizing application development. He specializes in Spring Boot and Kubernetes and is currently helping lead the charge on migrating key applications to a hybrid cloud environment, emphasizing secure and efficient engineering practices. \-\-\- **Talk 2: Adopting Kotlin for Spring 7: Cleaner Code, Fewer Bugs, Some Tradeoffs** *Speaker: Daniil Tsarev, JetBrains* Kotlin is becoming a first-class citizen in the Spring ecosystem, especially with the latest features in Spring 7. In this talk, we'll explore how easy it is to adopt Kotlin in existing Spring projects, what tangible benefits it brings to everyday development, and where some edges still are. Expect practical examples, real-world tradeoffs, and an honest look at whether Kotlin is the right choice for your Spring stack. **About the speaker:** Daniil Tsarev is a Software Developer at JetBrains with over 10 years of experience working with the Spring ecosystem. Previously was developing a Spring-based full-stack framework for enterprise solutions. Now passionate about developer productivity, he’s dedicated to creating tools and solutions that make developers’ lives easier. **📅 Agenda** [**18:30**]: Doors open, food, drinks & networking [**19:00**]: Talk 1: Secure and Seamless (K8s Secrets) [**19:45**]: Short break [**20:00**]: Talk 2: Adopting Kotlin for Spring 7 [**21:00**]: Q&A and more networking [**22:00**]: Closing the doors Come for the knowledge, stay for the community.

**Rust Berlin on location 🏳️‍🌈** is a new, informal in-person Rust meetup group in Berlin. We are a interactive meetup format interested in mob coding, deep diving and problem solving together. We build toy projects, share experiences, discuss technology and learn new cool stuff. And you are welcome to join! No matter if you are writing Rust production code every day, if you already contribute to Open Source projects or want to start doing so, if you use Rust in hobby projects or if you are just curious what the hype and buzz is all about, you are very welcome! To coordinate and plan activities, please join our **[Rust Berlin on location 🏳️‍🌈](https://signal.group/#CjQKIApfEgb36v82nhIb7m6zLCQjEtSEZubR7UvywTcWZXxdEhBWxhMWNCKekvtCYX7iDRRm)**[ Signal group](https://signal.group/#CjQKIApfEgb36v82nhIb7m6zLCQjEtSEZubR7UvywTcWZXxdEhBWxhMWNCKekvtCYX7iDRRm)! **Planned programme** Being an informal meetup, we are open to anything between just meet and talk, explore nerd snipes and rabbit holes, mob code together, plan and build fun projects, tinker with electronics, and presentations with Q&A. This time, Flix will walk us through error handling approaches in Rust — from typed error enums to crates like anyhow and thiserror — and present his own take: neuer-error, a single-type error library that captures source locations instead of backtraces and provides typed, discoverable error context without generics soup. Then Raf will show off a fun project that renders canvas primitives with vector and matrix geometry, built from scratch with zero dependencies. If someone brings other cool stuff, questions or problems, then let us dedicate the second half of the meetup time to that! Anyone is invited to bring their projects and questions, show something, ask something, or explore a topic together. The best conversations and deepest rabbit holes can emerge out of seemingly nowhere. **Projected upcoming meetups** We schedule regular meetups on Thursday evening every four weeks, using the slot between the Berlin Rust Hack and Learn online meetup (every two weeks), and the Rust Nuremberg online meetup (every four weeks). 19 February 2026 is our eleventh meeting. Our next projected meetings are going to occur on the following dates: * 19 Feb 2026 * 19 Mar 2026 * 16 Apr 2026 * 14 May 2026 (tentative, public holiday) * 11 Jun 2026 * 9 Jul 2026 * 6 Aug 2026 **Location** Our meetup location is the new shared office community space of Ferrous Systems, Slint and KDAB in Berlin Mitte, for up to 25 people. We are expecting to use this space as our default location for the time being, with the IN-Berlin e.V. community space in Moabit as backup. Regardless, as our group might eventually outgrow the locations' size limit, we are low-key looking for bigger locations. If you know a fitting location, then please let us know in our Signal group! Another workable way might be to split the meetup into smaller, interest-specific sub-groups instead. As the no-show rate on Meetup.com is rather high, consider showing up even if you are on the waiting list. We can't promise that there is any space left, but usually there is. So give it a shot! **Accessibility** The location has an elevator and a wheelchair accessible bathroom. Please note that the bathroom is two floors down from the meetup space. On our quest for a bigger location, we are going to pay special attention to accessibility. **Community** We aim to create a safe place for everyone and adhere to the [Berlin Code of Conduct](https://berlincodeofconduct.org/). Inclusivity is very important to us. If you are curious about Rust, but unsure if you are welcome to join: Yes, yes you are. Please come to the meetup! If you have special needs, please get in contact, we will try to accommodate you as best we can. We are part of [https://berline.rs/](https://berline.rs/) and like to hang out in the Berlin Rust Hack and Learn online meetup's [Matrix channel](https://matrix.to/#/!xycQxSjSAvEezkyztA:chat.berline.rs). You are very welcome to join!

Here's how it works: 1. At 10:15 everyone introduces themselves and briefly describes what brought them to Code & Coffee today (project, homework, networking, etc) 2. For the rest of the day, folks work in the communal space on their projects providing one another help and conversation as needed. Oh and they usually drink coffee and tea too! That's it! Hope to see you there! **Location** Our hosts are the Fairfax City Economic Development Building: [10300 Eaton Pl, Fairfax, VA 22030](https://www.bing.com/ck/a?!&&p=d7298231ca2df594df822003f9a93517c788fceefe1fcbb79c8976696e341bc6JmltdHM9MTc1MzIyODgwMA&ptn=3&ver=2&hsh=4&fclid=180d0745-3b7f-69a1-23a2-11433a7868e5&u=a1L21hcHM_Jm1lcGk9MTA5fn5Ub3BPZlBhZ2V-QWRkcmVzc19MaW5rJnR5PTE4JnE9RmFpcmZheCUyMENpdHklMjBFY29ub21pYyUyMERldmVsb3BtZW50JnNzPXlwaWQuWU44NzN4ODI4MTk2Mjg0NTk5MDM4MTU0MiZwcG9pcz0zOC44NjE0NDYzODA2MTUyMzRfLTc3LjMwMjE3NzQyOTE5OTIyX0ZhaXJmYXglMjBDaXR5JTIwRWNvbm9taWMlMjBEZXZlbG9wbWVudF9ZTjg3M3g4MjgxOTYyODQ1OTkwMzgxNTQyfiZjcD0zOC44NjE0NDZ-LTc3LjMwMjE3NyZ2PTImc1Y9MSZGT1JNPU1QU1JQTA&ntb=1) Conference Room A- Large, Floor 1 This is a new venue for us, so give us some time to get more details about it.

**In a time of division and isolation, come be part of the community that's rebuilding the town square, one table at a time.** In BreadBreakers, we use the common space of the dining table to have conversations where neighbors can **hear, be heard, and know one another.** If you're hungry for good discourse and deeper community, join us for a Community Dinner in Reston and help blaze the trail to a healthier, more connected society and democracy. Here’s how it works: For just two hours, multiple tables of people set aside the need to "win" and instead focus on sharing, listening, and connecting. Guided by experienced table hosts, we'll tell our stories, try to understand each other, and practice being in community with those with different views or backgrounds. **At this dinner, participants will get to choose between three different topics, including some current events.** Topics range from the political, to the spiritual, to the philosophical, to the off-the-wall - but no matter which table you choose to sit at, you can be sure it'll be like no dinner conversation you've had before! You can also **suggest a topic** by emailing us at [BreadBreakersInfo@gmail.com.](http://BreadBreakersInfo@gmail.com./) Food will be provided for free. For those who wish to provide a donation to help fund BreadBreakers, you can [give here](https://pushpay.com/g/restorationrestonumc?fnd=pO6G-N7oO7FH7Mp1u-x6mA&fndv=Lock&r=No&lang=en&src=pcgl) or at the event. We'll have vegetarian and gluten-free options available. If you have any additional dietary restrictions (Celiac Disease, vegan, etc.) please let us know at [BreadBreakersInfo@gmail.com](mailto:BreadBreakersInfo@gmail.com) so that we can implement the appropriate food handling procedures. **Join us, invite a friend, and be a part of the movement to mend our fractured society and normalize a better way of talking with one another.** BreadBreakers, an initiative by [Restoration United Methodist Church](https://restorationreston.org/breadbreakers) in Reston, VA, is a religiously inclusive community. All faiths and all stripes are welcomed. Our leadership, volunteer team, and community include people who attend Restoration and people who don't. \~ Michael

We will be meeting at Starbucks to learn together. Come with an online class you're already going through or an interest and we will try to connect you with a course where you can learn it. Already have a skill you want to contribute to a Kaggle Datascience competition? We will work on these too! Laptop required :)
