Welcome to LGTM - Programming in the Age of LLMs! At this new meetup, we're going to discuss the human side of LLM coding – how AI tools affect the way we build software, how we collaborate and how we feel about the transformation of our craft. We'll also mingle & have fun! **• LLM-assisted coding - A Systems Perspective** ([Dragan Stepanović](https://bsky.app/profile/dstepanovic.bsky.social)).

**Kurzbeschreibung** Afterwork-Brainwalking von ARC Live über Veränderung, Klarheit und neue Perspektiven. **Beschreibung** Walk of Change ist ein neues Format von ARC Live in Berlin. Nach einem Tag voller Meetings, Mails und Bildschirme bietet der Walk of Change einen anderen Raum: Bewegung, frische Luft, gute Fragen und Austausch auf Augenhöhe. Wir sitzen nicht vor einem Bildschirm und sprechen über Veränderung. Wir gehen los. Schritt für Schritt. Wir nutzen Brainwalking als Methode für besseres Denken in Bewegung: Gehen, Nachdenken und Austausch verbinden sich zu neuen Perspektiven. Der Walk of Change ist offen für alle, die Veränderung im beruflichen Kontext erleben, gestalten oder besser verstehen möchten. Es geht nicht um einen Vortrag, keinen Pitch und keine Tool-Demo. Es geht um Bewegung, Austausch und neue Perspektiven. **Thema dieser ersten Session:** Raus aus der Unklarheit **Leitfrage:** Was hilft uns, in Zeiten von Veränderung wieder klarer zu sehen? Du musst keinen Fall vorbereiten und kein konkretes Problem mitbringen. Du kannst den Walk nutzen, um für dich selbst nachzudenken, dich locker mit anderen auszutauschen oder tiefer über Veränderung, Klarheit und Perspektiven zu sprechen. Unsere Route startet am **Platz des 09. November 1989**, einem Ort, an dem Veränderung in Berlin unmittelbar sichtbar wird (S-Bhf. Bornholmer Straße). Von dort gehen wir in Richtung **Bernauer Straße / Gedenkstätte Berliner Mauer**, durch einen Stadtraum, in dem Grenzen, Übergänge und Neubeginn sichtbar werden. Der Walk ist keine Stadtführung, sondern ein geführter Reflexionsspaziergang mit einer gemeinsamen Leitfrage. Und ganz nebenbei kommen wir nach einem langen Arbeitstag wieder in Bewegung. **Format** Der Walk dauert ca. 2 Stunden und folgt einem einfachen, offenen Rahmen. Wir starten mit einer kurzen Begrüßung, einer Einführung in das Format und der Leitfrage des Abends. Danach gehen wir gemeinsam los, in wechselnden Gesprächen, kleinen Gruppen oder auch zeitweise still. Die Leitfrage begleitet den Walk, ohne dass daraus ein Workshop oder eine Beratungssession wird. Unterwegs gibt es kurze Reflexionsimpulse oder Gesprächsfragen. Du entscheidest selbst, wie tief du einsteigen möchtest. Zum Abschluss sammeln wir freiwillig, was jede:r mitnimmt: eine Frage, eine Beobachtung, eine Erkenntnis oder vielleicht einen nächsten Gedanken. **Wichtig** Bitte bring bequeme Schuhe, wettergerechte Kleidung und Neugier auf Veränderung mit. Das Event findet draußen statt. Bei starkem Regen oder Unwetter passen wir das Format kurzfristig an. **Treffpunkt**: Platz des 09. November 1989, Bornholmer Straße **Ziel / Richtung**: Bernauer Straße / Gedenkstätte Berliner Mauer **Sprache**: Deutsch **Dauer**: ca. 2 Stunden **Format**: Afterwork-Spaziergang, Reflexion, Austausch **Vorbereitung**: keine notwendig **Begleitet von:** Anthony B. Holtz, Entwickler von ARC

This hike follows sandy woodland trails and quiet paths along the Havel River, gradually climbing through the forest to reach some of Berlin’s best vantage points. We’ll climb the steps of the historic Grunewaldturm before stopping for a relaxed break at Kaisergarten am Grunewaldturm, a traditional beer garden overlooking the river. From there, we continue through the forest and up to the summit of Drachenberg, where wide views open out across the Grunewald and the distant Berlin skyline. It’s a chance to leave the busy streets behind, enjoy some fresh forest air, and spend the day exploring one of Berlin’s most beautiful landscapes with a group of curious explorers. **WHAT ARE SOME OF THE HIGHLIGHTS?** **Grunewald:** Berlin’s largest forest, filled with sandy trails, glacial hills, and quiet lakes. A favourite escape for those looking for nature just outside the city. **Havel River:** One of the major rivers of the Berlin-Brandenburg region. Here the river widens into large lakes and peaceful bays surrounded by forest. **Grunewaldturm:** Built in 1899, this historic observation tower rises above the forest overlooking the Havel. Climb the steps to enjoy wide views over the lakes, woodland, and the distant Berlin skyline. **Kaisergarten am Grunewaldturm:** A classic German beer garden beside the tower. With views across the river, it’s the perfect place for a relaxed break, a drink, or a snack. **Drachenberg:** One of Berlin’s best viewpoints. From the top you’ll see a sweeping panorama across the Grunewald, Teufelsberg, and the Berlin skyline — a memorable way to finish the hike. **WHAT IS THE PLAN?** * **10:30 –** Meet at Nikolassee Station and kick-off with brief introductions before starting our hike into Grunewald Forest. * **11:30 –** Continue hiking the hilly forest trails along the Havel, taking breaks as desired at any of the numerous benches with beautiful lake views. * **14:30 –** Arrive at the Kaisergarten am Grunewaldturm Biergarten for a well-deserved lunch and climb the Grunewaldturm. * **15:30 –** Continue hiking through the peaceful Grunewald Forest and over Teufelsberg towards Drachenberg. * **18:15 –** Reach the top of Drachenberg and take a break to soak up the panoramic views. * **19:00 –** Walk down Drachenberg towards the end station. * **19:20 –** Arrive at Heerstraße Station to conclude our adventure. **WHAT IS INCLUDED?** * Community leader & guide for the entire duration * Access to Google photos album dedicated for this trip for sharing all your amazing pics & videos from the trip. * Access to a WhatsApp group for confirmed participants. **OPTIONAL ADD-ONS:** * Entry to the Grunewaldturm viewing platform is optional.

**Everyone's welcome ❤️** Every Friday evening we meet up by the Spree — music playing, people arriving from all over the world, and a night that usually goes way longer than anyone planned. No agenda. No organised icebreakers. Just a relaxed spot by the river where you can show up, grab a drink, and actually meet people worth knowing. We've been doing this for over 8 years, and the best thing about it is still the same — you never quite know who you're going to end up talking to. Come solo, come with friends, come fresh off a flight. The crowd is always a mix of Berliners, expats, travellers, and people who just moved here and are figuring it out. After a while the group usually spreads out to bars or clubs — or just stays by the water. You go wherever the night takes you. **Stay in the loop — join our Telegram group:** Spree Ravers → https://linktr.ee/clockworkbanana 📍 By the Spree, next to Schlesisches Tor U-Bahn — opposite the East Side Gallery, right by the Cage on Water → [https://maps.app.goo.gl/vj1DhSP3apijCmRbA](https://maps.app.goo.gl/vj1DhSP3apijCmRbA) 🕒 From 9 PM — people arrive gradually, so if it's quiet at first, just hang tight See you Friday ✨

The longest day of the year is comming and let's another Kotlin meetup. This time we geather at N26! **⚠️⚠️⚠️ Due to a venue policy please submit the following form for additional details. Without it, you won't be allowed inside the venue:** https://forms.gle/XjqVXkD3FARCM6jA8 **Line-Up:** 👉 **TestBalloon: Kotlin testing is easier (and more fun) than you think** *by Oliver Okrongli* You want an easier way to write tests? Parameterize tests in plain Kotlin? Reuse a series of tests? Easily extend own your test setup? Have first-class support on all platforms? All without struggling with a huge framework API? TestBalloon is a new test framework that brings the power of Kotlin to your test setup. With a small-surface API, a hierarchical test structure and an extensible DSL, TestBalloon makes Kotlin testing easy, even at scale. Oliver, the author of TestBalloon, will show testing patterns and strategies and lots of practical examples, ranging from simple unit tests with less boilerplate to advanced testing with coroutines and generated data. This talk is based on insights first presented at KotlinConf 2026 in Munich. At the end of this talk, you’ll be able to firmly the answer the question: "How can I master Kotlin testing with ease, and make my team release with joy and confidence, every time?" 👉 **One Topic to Rule 'Em All** *by Yonatan Karp-Rudin* Kafka delivered every event exactly once, in order, and lost nothing. So what broke? This talk follows that question into the gap most event-driven systems leave open: what actually guarantees the order your domain depends on, and what quietly doesn't. We start from a real log line, find the crack in an architecture that looks clean and ships fast, and rule out the fix everyone reaches for first. The cure turns out to be one sentence of domain thinking plus one line of config, though the Schema Registry will fight you on the way there. A live demo runs the bug and the fix back to back: same load, same hero, one change. If you build with Kafka, you have probably shipped a version of this bug. You will leave able to spot it and fix it before it pages someone. 👉 **TBD** **Speaker Bios:** 🗣 Oliver Okrongli Oliver has been shaping and creating software from backend to frontends. He is the author of TestBalloon, a next-generation Kotlin test framework. Before, he has helped to maintain Kotest, and contributed to several libraries of the Kotlin ecosystem as well as the Kotlin compiler. Can be found on GitHub (OliverO2) and the kotlinlang Slack (Oliver O). When not developing, he is most probably in deep talks, dancing, snowboarding or F18 catamaran sailing whenever he gets a chance. 🗣 Yonatan Karp-Rudin Yonatan Karp-Rudin is a Staff Engineer at Billie, building event-driven systems in Kotlin and Spring Boot. Off the clock, he plays with AI agents and builds random tooling, trying to hand off as much of his own workflow to a machine as he can. The rest of the time he's brewing mead or deep in a video game. **🗣 TBD**

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD
