Smalltalk

**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 B2 * **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**

DEUTSCH SIEHE UNTEN ==== Our silent walks are finally here. We challenge you to join us in the next two weeks for a daily silent walk in the morning through Hasenheide. **In a nutshell:** we meet at 07:55 am in front of Little Johns Bikes (1 minute walk away from metro Südstern), and at 08:00 am we start walking together into Hasenheide for a one-hour loop, finishing where we started. It is a completely silent activity, from start to finish, from hello to goodbye, and we ask you to respect that. Even if you come with friends, please do not talk during the walk. **Why should you join these walks?** The idea is to create space for a few simple things. First, a chance to start the day by being outside and seeing morning light for a longer stretch of time. Morning light helps regulate our circadian rhythm, and being outdoors makes that light much more effective than staying inside. Second, a chance to be together without small talk, or any talk at all. We invite you to feel accompanied without having to think about what to say or make conversation. Third, a chance to take some mindful time. While we walk, we invite you to notice the park around you and stay in the moment. What was your favourite bird today? How many bikes passed us? What sound do our steps make on grass, and how does that change on gravel? We will offer one optional daily question or challenge to help you stay grounded. And fourth, a chance to move, which is simply a great way to start the day feeling good. ===== Wir laden euch ein, in den nächsten zwei Wochen jeden Morgen mit uns einen stillen Spaziergang durch Hasenheide zu machen. **Kurz gesagt:** Wir treffen uns um 07:55 vor Little Johns Bikes, nur eine Minute zu Fuß von der Metrostation Südstern entfernt, und um 08:00 gehen wir von dort gemeinsam in Hasenheide und machen dort eine einstündige Runde, die wieder am Ausgangspunkt endet. Es ist eine komplett stille Aktivität, von Anfang bis Ende, und wir bitten euch, das zu respektieren. Auch wenn ihr mit Freund\*innen kommt, sprecht bitte während des Spaziergangs nicht. **Warum mitmachen?** Die Spaziergänge bieten... Die Idee ist, Raum für ein paar einfache Dinge zu schaffen. ... eine Möglichkeit, den Tag draußen zu beginnen und das Morgenlicht über einen längeren Zeitraum mitzunehmen. Morgenlicht hilft dabei, unseren zirkadianen Rhythmus zu regulieren, und draußen ist dieses Licht viel wirksamer als drinnen. ... eine Möglichkeit, zusammen zu sein, ohne Smalltalk oder überhaupt reden zu müssen. Wir laden euch ein, euch begleitet zu fühlen, ohne überlegen zu müssen, worüber ihr sprechen sollt oder wie ihr ein Gespräch anfangen könnt. ... eine Möglichkeit, sich etwas achtsame Zeit zu nehmen. Während wir gehen, laden wir euch ein, den Park um euch herum wahrzunehmen und im Moment zu bleiben. Welcher Vogel hat euch heute am besten gefallen? Wie viele Fahrräder sind an euch vorbeigefahren? Wie klingen unsere Schritte auf Gras, und wie verändert sich das auf Kies? Jeden Tag geben wir euch eine optionale kleine Frage oder Beobachtungsaufgabe mit, die euch helfen kann, geerdet zu bleiben. Und eine Möglichkeit, sich zu bewegen, was einfach ein guter Start in den Tag ist :)

You are warmly invited to our next Omega Talk: ***PLANET EARTH — ONE CREW !*** ***What if we were all truly brothers and sisters ?*** Across the ages, through myths, sacred traditions, and the voices of great teachers, a deeper truth seems to shine through: that beyond all separation, humanity belongs to one shared origin and one living whole. From ancient flood stories to spiritual teachings, from the first beginnings of humankind to the image of Earth seen from space, we will follow a thread that gently leads us back to one essential question: Are we, in truth, one human family? This evening is an invitation to look beyond the visible divisions of the world and to sense the deeper unity that connects us — as human beings, as fellow travelers, as one crew on this planet. After the presentation, there will be time to create a warm space for reflection, connection and friendship over tea and snacks.

Dear Kotlineers, After a slightly longer break than planned - we are back! This time we meet in the chambers of **voize GmbH** \- one of Berlin's \(if not the\) most flourishing startups\. As the flowers open and the days stretch long, we're dancing into May with some talks. **Line-Up:** 👉 **Coroutines behind the scenes** by *Sergey Shkurov* Have you ever wondered how Kotlin coroutines actually work under the hood? In this talk, we dive into the JVM bytecode behind suspend functions and reconstruct the state machines step by step. You’ll follow a hands-on exploration of real compiled code and see how continuations and suspension actually work. 👉 **YOUR TOPIC HERE** by *TBD* **Speaker Bios:** 🗣 *Sergey Shkurov* A Kotlin enthusiast since 2019. 🗣 *YOUR NAME HERE* TBD

Bitte via Mail anmelden: anmeldung@gedoplan.de **Referent:** Martin Boßlet, Berater, Dozent und Softwareentwickler **Datum und Uhrzeit:** Donnerstag, 30.04.2026, 18:00 – ca. 19:30 Uhr **Ort:** Online mit Zoom Seit zwei Jahren reden alle über KI-gestützte Entwicklung - und vieles klingt gleich: Gestern war Prompt Engineering der Beruf der Zukunft, heute ist es Context Engineering. Claude Code gegen Codex, GitHub Copilot vs. Cursor, Tool-Vergleiche hier und da. Die Älteren unter uns werden sich mit einem Schmunzeln an Vim vs. Emacs erinnert fühlen. Während CEOs bis hin zum Digitalminister den Untergang der programmierenden Zunft ausrufen, wenden sich viele Entwickelnde frustriert ab. "Das ist nichts für mich" - diesen Satz hört man oft. Die Branche scheint sich in zwei Lager zu spalten: auf der einen Seite diejenigen, die KI fast schon aus Trotz konsequent ablehnen, auf der anderen KI-Propheten, die zumindest der Erzählung nach ihren kompletten Alltag mit KI bestreiten und der Konkurrenz schon längst meilenweit voraus sind. Die eigentliche Frage lautet: Warum gehen die Erfahrungen so weit auseinander? Die These dieses Vortrags: Der Engpass liegt meist weder im Modell noch im nächsten "Tool du jour", sondern in fehlendem, verstreutem oder nur implizit vorhandenem Kontext. Der Schlüssel zu erfolgreicher KI-Zusammenarbeit liegt deshalb nicht in besseren Tools oder clevereren Prompts, sondern in der ältesten Technologie der Menschheit - Sprache. Genauer gesagt: in Markdown als universeller Schnittstelle zwischen Mensch und Maschine. Anhand von Architecture Decision Records (ADRs), Mermaid-Diagrammen, **[AGENTS.md](https://www.linkedin.com/safety/go/?url=http%3A%2F%2FAGENTS%2Emd&urlhash=jh-H&mt=F7bnie71WnYrGR3aD-BiSMeaQCiWniKDxaG65SbBgq37lq5u7OZ1P6NjRp-YTlrvhyBy30Lf47AWfYCmtVLwNg99MBUc-2e8qYUzQLXNViKKD4LeW5gizS3yWw&isSdui=true)**-Datei und Agenten-Skills zeige ich, warum Text-First Development kein Retro-Trick ist, sondern ein praktikables Arbeitsmodell für die KI-Ära. Wer Architektur, Entscheidungen und Konventionen in Text statt in Tickets, Chat-Verläufen oder auch nur an der Kaffeemaschine festhält, bekommt bessere KI-Ergebnisse, mehr Präzision und weniger Nacharbeit. Und ganz nebenbei entsteht endlich wieder etwas, das in der Softwareentwicklung jahrzehntelang zu teuer war: aktuelle, brauchbare Dokumentation für Mensch und Maschine. Kein Talk über Prompt-Hacks, Tool-Vergleiche oder das Tool der Woche, sondern über eine einfache, praktische Frage: Wie müssen wir Software bauen, damit KI-Unterstützung nicht nur beeindruckend wirkt, sondern dauerhaft nützt? Die Antwort ist überraschend einfach: kein Tool-Zirkus, kein Hokuspokus. Einfach nur Text. Nach Ihrer Anmeldung schicken wir Ihnen den Anmeldelink zu.

Hello everyone, After a great restart last month, we’re happy to invite you to the next Rust Berlin meetup at the JetBrains office. We’ll stick to the classic format: an evening with two main talks, followed by time to connect, discuss, and catch up with the community. Finger food and drinks will be available throughout the evening. **Agenda** * Doors open: 18:30 * Start: 19:00 * Short welcome and updates from JetBrains * 2 talks (20–30 minutes each) * Open mic / lightning talks (optional, a few minutes each) * Networking **Speakers** Egor Lebedev - Welcome and a short note from the RustRover team Till Adam - Slint-MCP In this talk, Till will walk you through the implementation of the MCP server for the Slint GUI framework - and how it's implemented in Rust. He will walk you through the implementation from design to implementation. Gaurav Gahlot - Rust meets Kubernetes This talk is a hands-on walkthrough using kube-rs. We'll connect to a cluster, query pods, watch real-time events via async streams, and build a minimal controller - all in Rust, all running live. **Speaker Bios** Till Adam is the CCO at KDAB and has been working on open-source since the 90s. Originally a C++ company, KDAB has been working with Rust for the last 8 years. One of their biggest projects is CXX-Qt. Their specialization on the Rust side is use in hybrid, high-performance, high-correctness codebases. Gaurav Gahlot is a Software Engineer with experience building scalable platforms with Go, Rust, and Kubernetes. He maintains the CNCF Akri project and actively contributes to open source. **Open mic & future talks** We’ll reserve a few short slots for anyone who wants to share something with the group. This can be a quick idea, a project, or an experience. Slides are optional. If you’re interested in giving a longer talk at a future meetup, this is also a good opportunity to connect with the organizers. **Venue & access** Please arrive on time. We will have someone at the entrance to let people in between 18:30 and 19:15. After that, access becomes more difficult as the doors are locked and require manual opening. **Registration** The venue has limited capacity and events typically fill up with a waiting list. If you register and can no longer attend, even at short notice, please un-RSVP so someone else can take your spot. Looking forward to seeing you all!

**Relax. Connect. Create. ☕** After a full week of work, meetings, study sessions and life in fast-forward, it’s time to slow down. Join us this Saturday afternoon in Berlin for a relaxed coffee hang-out where this week's agenda is good company & warm drinks. You're also invited to bring some boardgames, drawing/coloring materials (I will bring an adult coloring book) **What’s the plan?** We’ll meet in a cosy spot, draw, chat about everything and nothing, swap stories and simply enjoy the moment. No pressure. No formalities. Just a bunch of friendly people sharing a Saturday coffee. **Who’s welcome?** Everyone! Whether you’re a Berliner born and raised, newly arrived in the city, from Germany or abroad, if you like meeting open-minded folks and spending some relaxed time—come join us. **When & how?** Saturday afternoon. Detailed time and place in our Telegram group. ➡️ Join us on Telegram: [https://t.me/berlinsaturdaycoffee](https://t.me/berlinsaturdaycoffee) Hop in, say hello, and we’ll share the final details. **Why join?** * Because you deserve a break. * Because you enjoy being creative. * Because you enjoy boardgames * Because meeting new people sparks fresh energy. * Because coffee tastes even better when shared. * Because Saturday afternoons were made for this. Respect and Safety: There is always at least one organizer present at every meetup. If you ever feel unsafe or bothered by someone’s behavior, you can reach out to an organizer privately. Your identity will remain confidential, your concern will be taken seriously, and no inappropriate behavior is tolerated — anyone making others feel uncomfortable will be removed from the group immediately. We hope to see you there. Bring yourself, your smile, drawing materials, your stories—or just your comfy self. Let’s make Saturday a little more laid-back, a little more social and a lot more nice. See you soon! —Your Saturday Creative Coffee Crew ☕

**ℹ️ The next meetups will be managed on Luma.** **You can register for this event 👉 [here](https://luma.com/zma43t8d). Follow the Django User Group Berlin Calendar on Luma.** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-​ In April, we'll be hosted again by [MPB](https://www.mpb.com/de-de?utm_source=luma), the second-hand market for camera and video equipment, running good ol' Django. Be sure to chat to them while you sample their food and drinks. This month, like last, we'll have a speaker from within our own community, **Sofia Fischer**, Backend Developer at Kraken Technologies. The title of her talk is: "**How complex is my function?**". This talk will give an overview of complexity metrics in computer science, software engineering, and linguistics to show many different ways in which a function may be complex. Based on the Django Framework repo, I will show how a project can be analysed with different complexity metrics. As always, please make use of the **lightning talks** and talk about anything you like: a problem that you'd like help with, a thing you've built, or a hobby you like. Doesn't have to be Django, doesn't even have to be tech! **18:30 Doors open** **19:00 Main talk by Sofia Fischer** **19:30 Lightning talks** **19:45 Get eatin'** This event is governed by the **[Berlin code of conduct](https://berlincodeofconduct.org/de/?utm_source=luma).** We want this to be a safe space for all. Any questions and concerns can always be directed towards the organizers Lara Krämer ([lara.softwareengineer@gmail.com](mailto:lara.softwareengineer@gmail.com)) and Markus Binsteiner ([markus@frkl.dev](mailto:markus@frkl.dev)) before, at and after the event. **Accessibility information:** The main entrance can be accessed via stairs or a ramp.
