„Die Liebe ist eine aktive Kraft im Menschen, eine Kraft, die die Mauern niederreißt, welche den Menschen von seinen Mitmenschen trennen.“ - Erich Fromm Hey ihr Lieben, ich bin Sofie (24, Studentin - Psychotherapiewissenschaften) und möchte gerne einladen zu einem Lesekreis des Buches „Die Kunst des Liebens“ von E. Fromm. Wer ist Erich Fromm? Erich Fromm (1900–1980) war ein deutsch-amerikanischer Psychoanalytiker, Sozialpsychologe und Philosoph. Er gehört zu den bedeutendsten Denkern des 20. Jahrhunderts und verband psychoanalytische, sozialwissenschaftliche und humanistische Ansätze in seiner Arbeit. Fromm beschäftigte sich intensiv mit den Auswirkungen der modernen Gesellschaft auf den Menschen und setzte sich für eine menschlichere, weniger von Konsum und Machtstreben geprägte Welt ein. Die „Kunst des Liebens“ schreibt er als humanistische Gegenrede zu einer modernen Welt, die Nähe will, aber keine Beziehungskompetenz ausbildet. Dabei romantisiert er die Liebe nicht sondern nimmt sie radikal ernst - als eine erkennbare Fähigkeit und eine ethische Haltung in einer entfremdeten Gesellschaft. Ich beschäftige mich nun schon etwas länger mit E.Fromm und finde seine Werke aktueller denn je. Gerade in Zeiten des Hasses und Spaltung, freue ich mich mit euch einen Raum zu schaffen, in dem wir uns anhand des Buches mit dem Thema „ Liebe“ auseinandersetzen und uns auf eine neue Perspektive einlassen, die das Buch eröffnet. Ziel ist es uns mit dem Buch auseinander zu setzen und gemeinsam in Kontakt darüber zu gehen. Interessierte Menschen sind herzlich willkommen! WANN und WO? Der Lesekreis findet alle zwei Wochen Mittwoch 20 Uhr in der gemütlichen Bademeister Bar in 13088 Berlin statt. Mitzubringen ist euer Buch (ISBN- 978-3423361026). Ihr braucht sonst keine Vorkentnisse oder Vorwissen :)) Ich freu mich auf euch! Max. 10 Personen Toleranz, Respekt und Offenheit sind die Grundlage ! Alle sind willkommen!

**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!

**Hi everyone!** We’ll now be meeting twice a week at Denizen House (Köpenicker Str. 40, 10179 Berlin), on **Mondays and Wednesdays**! * **Mondays:** levels A1 to B1 * **Wednesdays:** levels B1 to C1 We work with dedicated materials tailored to each level, so everyone will have a place to practice and improve. **Event schedule** * **18:00 – 18:30** Arrival and registration * **18:30 – 19:50** Sprachcafé * **19:50 – 20:00** End and clean up Please be aware that the moderated event starts at **18:30**. Before this time, we are busy setting up the space. Registrations usually take place around **18:15 / 18:20**. Participants are kindly asked **not to arrive too far in advance** at the house. If someone arrives much earlier, Denizen may ask them to pay either for a drink (consumption) or for a **day pass**, as the space is a co-working environment during the day. **Please remember, our event is only happening from 18:00 to 20:00** **How the Sprachcafé works** We use different materials to help participants gain confidence in German. Together with whiteboards and our volunteers, the Sprachcafé is based on **interactive conversations** in small groups. **Participation fee** The Sprachcafé has a **participation fee of 5 €**, which helps cover organizational costs and **includes one soft drink for free**. Tickets can be purchased directly on the day of the event, card and cash payments are accepted. As the Sprachcafé has become very popular, we now need to **limit the number of participants**. Please understand this measure; it ensures that everyone has a comfortable space to practice. We kindly ask you to be **rücksichtsvoll** and only RSVP “Yes” if you are certain you can attend. If your plans change at the last minute, please update your RSVP so someone on the waiting list can take your spot. Getting your ticket early can help secure your place. **Please note** Our event will begin **promptly** at the scheduled start time. If you arrive late, we cannot guarantee your participation, even if you have a ticket or have RSVP’d. We encourage all guests to arrive on time to ensure a smooth and enjoyable experience for everyone. Thank you for your understanding and cooperation. **About Denizen** Denizen is a new-style co-working space focused on being an integral part of local communities. Located on the ground floor of the historic Eiswerk on Köpenicker Straße in Kreuzberg, Denizen House is a communal place providing work, refreshment, and recreational facilities throughout the day. Think of it as a living room for the neighborhood. If you have any questions, don’t hesitate to let me know. If you’d like to contribute to this night, send me a message! Ich freue mich schon! Grüße, **Nacho**

Save the date! The Mozilla Meetup series continues with talks focused on modern web technologies. To account for typical **no-show rates**, we’ve opened more RSVP spots than we can physically accommodate. Based on our last event, only about 36 of 100 registered participants (including Mozillians) attended in person. **We will admit attendees on a first-come, first-served basis and will need to close the doors once we reach room capacity (around 50 people).** Note that this event operates under the [Mozilla Community Participation Guidelines](https://www.mozilla.org/about/governance/policies/participation/). **18:00** \- Doors open **18:30** \- Tracking \(Protection\) Everywhere There are a variety of tracking vectors on the web. But how exactly does this tracking work and what mechanism do we have available to protect our privacy? This talk takes a closer look at the many anti-tracking mechanisms Firefox uses to protect its users, and discusses the threat models behind them and the practical protection they provide. Bio: Manuel Bucher is a software engineer on the Firefox Privacy team working on anti-tracking in Firefox **19:30:** No Servers, No APIs: AI in the Browser I’ll present how modern web technologies make it possible to run AI models directly in the browser combining WebLLM and WebAssembly to deliver powerful, privacy-preserving client-side AI experiences. For more context, here’s a related article I wrote for Mozilla AI: [https://blog.mozilla.ai/3w-for-in-browser-ai-webllm-wasm-webworkers/](https://blog.mozilla.ai/3w-for-in-browser-ai-webllm-wasm-webworkers/) **Bio:** Barış Güler is an engineering leader working on in-browser AI systems that leverage WebLLM, WASM, and web platform features to bring AI inference and tooling into client environments. He writes about web-native AI and open-source approaches to privacy-first machine intelligence (and a Rust fan, for sure).

**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!

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.

NOVA Code and Coffee is an inclusive, informal, co-working session. People of all skill levels are invited. The concept is simple, bring a laptop and ideas, we'll provide the coffee and donuts! 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!
