**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!

**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!

Movie Lovers, ReSee and the Zeitgeist Zentrum are teaming up for another edition of Zeit für Deutsch, our monthly, donation-based movie event taking place at the Zeitgeist Zentrum Sprachschule in Wedding. At each event, we'll screen a different German language film and spend a little time before and after the movie chatting amongst each other, speaking as much or as little German as you'd like, and just coming together as a community for a relaxed, low-pressure movie night. This time around we're showing a classic German thriller taking place all around Berlin. It follows a woman named who needs to obtain 100.000 marks in 20 minutes to save the life of her boyfriend. You know the one - but if you've never seen it, now's your chance! • Doors open at 2:30pm • Film starts at 3pm • Guests are encouraged to stick around and speak a little German after, but there's no pressure. This is 95% fun, 5% German practice :) Space is limited, so grab a spot and mark your calendars. Donations are also welcome at the door. RSVP on Luma to reserve your spot: https://luma.com/6bswkqh1 ​We hope to see you there 💜

**⭐ NOTE THE NEW LOCATION! ⭐** The Creative Code Jam is a monthly gathering of artists, makers, designers, illustrators, coders, musicians, performers, learners and anyone interested in the use of computing skills for artistic expression.

WHAT SHOULD I EXPECT? **Bring a laptop** and/or anything you’d like to work on, whether it’s a personal project, an experiment, or a skill you want to learn. You can come with friends or meet new people here. There’s no set agenda: some people code, some sketch ideas, some collaborate, and others just chat and get inspired. SCHEDULE Doors open at noon, then we’ll have quick introductions so everyone can share what they’re planning to work on. Note: arriving on time is the best way to hear what others are up to ;) Around 6 pm, we gather to share what we’ve worked on during the day. BEGINNERS WELCOME! If you’re new to creative coding, we'll be happy to help you get started, and you can find beginner-friendly resources at [creativecode.berlin/learn](http://creativecode.berlin/learn).

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

This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them. Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance". Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you. The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life. Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.
