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)). About the speaker: Dragan is Principal Engineer at [gigs.com](https://gigs.com/). He's an expert in Extreme Programming and Theory of Constraints, as well as a prolific conference speaker. **• Agentic Support Ticket Investigation** ([Irmela Göhl](https://www.linkedin.com/in/irmela/)): Our team spent 6-10 hours a week manually investigating support tickets across multiple backend systems. This talk traces our iterative path from a hackathon prototype to a fully automated triage agent that investigates tickets before a human even opens them, shifting the job from "investigate" to "validate and decide“. About the speaker: Irmela is Engineering Manager at 1KOMMA5º, where she leads the teams building the Heartbeat app that helps customers track how their home energy system is optimized to always use the cleanest and cheapest electricity. • **When Code Gets Cheap: What Happens to Product Management?** ([Igor Bakman](https://www.linkedin.com/in/igor-bakman/)): When code gets cheap, choosing what to build becomes the hard part. This talk shares startup stories on how LLM coding is reshaping Product Management, engineering ownership, and the SDL About the speaker: Igor Bakman is a technology and product leader with 20+ years of experience building teams, platforms, and AI-enabled products across health tech, e-commerce, and other domains.

Hast du Angst, vor Publikum zu sprechen? Verlangt dein Beruf Präsentationen, Pitches oder Vorträge? Wirst du nervös, sobald alle Augen auf dich gerichtet sind? Verlierst du manchmal den roten Faden oder merkst, wie deine Zuhörer gedanklich auf Wanderschaft gehen? Dann bist du bei uns genau richtig. Bei Toastmasters trainierst du deine Redekunst in einem sicheren, wertschätzenden Umfeld. Schritt für Schritt. Rede für Rede. Mit klarem Feedback und echter Unterstützung. Hier wächst nicht nur deine Technik, sondern auch deine Präsenz. ## So läuft ein typischer Abend ab 🎤 Der Abend wird von **Alexandra, unserer Präsidentin**, eröffnet. Sie führt durch das Programm und sorgt dafür, dass sich Gäste wie Mitglieder gleichermaßen willkommen fühlen. ### 🗣 Vorbereitete Reden (meist 4 Reden à 5–7 Minuten) In der Regel erwarten dich vier vorbereitete Reden. Persönlich, inspirierend, humorvoll oder nachdenklich. Jede Rede dauert zwischen 5 und 7 Minuten und ist Teil eines individuellen Lernwegs. ### ☕ Pause Zeit zum Austausch, Durchatmen und Kennenlernen. ### ⚡ Stegreifreden (1–2 Minuten) Hier wird es spontan. Ein Impuls, eine Frage, ein Gedanke. Auch **mutige Gäste** dürfen sich ausprobieren und ganz ungezwungen Bühnenluft schnuppern. ### 📝 Feedbackteil Nun kommt der vielleicht wichtigste Teil des Abends. * **Bewertungsreden** zu den vorbereiteten Reden (je 2–3 Minuten) * Feedback weiterer Rollen wie Zeitnehmer oder Sprachstilbewerter * Ein **Gesamtbewerter**, der den Abend als Ganzes reflektiert Das Feedback ist konstruktiv, konkret und immer wertschätzend. Es zeigt Stärken auf und gibt klare Impulse zur Weiterentwicklung. ### 👋 Verabschiedung Zum Abschluss rundet Alexandra den Abend ab und gibt einen Ausblick auf kommende Treffen. ### 🍽 Danach: Restaurant & Socializing Wer mag, kommt mit ins Restaurant. Dort wird weitergeredet, gelacht, diskutiert und vernetzt. Wenn du lernen willst, klarer zu sprechen, souveräner aufzutreten und deine Botschaften wirkungsvoll zu platzieren, dann komm einfach zum nächsten Clubtreffen. Die Bühne wartet nicht auf Perfektion. Sie belohnt Mut. ✨

Curious newcomers are always very welcome, but expect in-depth conversations (see the former topics at [bitdevs.berlin](https://bitdevs.berlin)). * Chatham House Rule applies: you may share what was discussed, but not who said it. No livestream, no photos, no recordings. * The evening begins with food and networking; people often stay after the seminar to keep talking. **Co-hosted by:** * [Felix](https://x.com/FelixWeis) * [Freerk](https://x.com/freerko) * [Fabian](https://x.com/fjahr) For background on the idea of BitDevs Socratic Seminars, see [this article](https://bitcoinmagazine.com/articles/op-ed-want-to-learn-about-bitcoin-try-a-local-socratic-seminar).

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**

Welcome to Sunday Tech Coffee. This is a **networking** event for those in the tech industry in Berlin. We are usually inside and to the right. Ask the barista/bartender if you can't find us.

Hallo liebe Java User Group Mitglieder! Diesmal haben wir zwei Bonner Kollegen zu Gast: * Martin Stoller: **Backend-Performance in Hochlast-Systemen: Lösungsansätze aus dem Data Engineering** * Andreas Monschau: **Zehn goldene Regeln, um dein Softwareprojekt zuverlässig zu ruinieren** Wir freuen uns euch zu sehen (virtuell oder vor Ort). Dank an [codecentric](https://www.codecentric.de/standorte/nuernberg) für Location, Bier und Pizza! ================= Viele Hochlast-Systeme beginnen als kleine, unscheinbare Prototypen - gebaut mit bewährten Mitteln wie relationalen Datenbanken, objektorientierter Business-Logik und klassischen Request-Response-Architekturen. Doch was passiert, wenn diese Systeme plötzlich nicht mehr Tausende, sondern Millionen von Requests bedienen oder Terabytes an Daten verarbeiten müssen? In der Praxis zeigt sich häufig: Klassische Optimierungen wie Caching, horizontale Skalierung oder effizientere Algorithmen stoßen irgendwann an ihre Grenzen, weil sie innerhalb desselben Paradigmas bleiben. Dieser Vortrag zeigt, warum echte Skalierbarkeit oft ein Umdenken erfordert. Anhand eines durchgehenden Praxisbeispiels wird schrittweise demonstriert, wie sich ein System von einer latenzoptimierten Request-Response-Architektur hin zu einem durchsatzoptimierten, analytischen System entwickelt. Dabei werden zentrale Konzepte aus dem Data Engineering greifbar gemacht - darunter Precomputation, Batch Processing, deklarative Verarbeitung und Denormalisierung - und in den Kontext klassischer Backend-Entwicklung eingeordnet. Die Teilnehmenden lernen, typische Grenzen traditioneller Architekturen zu erkennen und erhalten ein alternatives Denkmodell, um High-Throughput-Systeme gezielt und nachhaltig zu skalieren. ================= Softwareprojekte sind chaotisch, anstrengend und voller Überraschungen. Und ganz ehrlich: So soll es auch bleiben. Ordnung würde ja nur den Spaß verderben. Trotzdem gibt es immer wieder Menschen, die glauben, man könnte Projekte wirklich zu Erfolg führen… unglaublich, oder? Damit dir so etwas nicht passiert, zeige ich dir in diesem Vortrag, wie du ein Softwareprojekt in 10 einfachen Schritten zuverlässig an die Wand fährst. Die „goldenen Anti-Pattern für maximalen Projektschaden“ entstammen jedoch nicht meiner Fantasie, nein, sie werden in der Realität täglich mit beeindruckender Konsequenz praktiziert. Und das Beste: Sie wirken nachhaltig. Manche dieser Muster entfalten ihre volle Zerstörungskraft erst Monate später. Nachdem du alle Regeln kennengelernt hast, kannst du selbst entscheiden: Möchtest du sie weiterhin anwenden, oder vielleicht doch etwas verändern? Solltest du allerdings inspiriert sein, eines dieser Anti-Pattern künftig noch konsequenter zu leben… dann sollten wir uns nach dem Talk dringend unterhalten. ================= Dein Vortrag bei der Java Usergroup Nürnberg! Hast du dich in letzter Zeit in deinem Projekt oder privat mit einem interessanten Thema beschäftigt? Vermutlich ist das nicht nur für dich selbst interessant! Hast du Lust, selber einmal einen Vortrag bei der Java-Usergroup Nürnberg zu halten? Wir sind nicht nur auf Java-Themen fokussiert, sondern beschäftigen uns gern mit und um alles über Software Entwicklung und IT. Wir wollen bei der JUG nicht nur bekannten Speaker\*innen eine Plattform geben und die neuesten State-of-the-Art Technologien vorstellen. Wir freuen uns auch besonders, wenn wir Themen aus unserem technologischen (Arbeits-)alltag Raum geben zu können. Melde dich gerne bei uns, wenn du dazu Lust hast, wir geben wenn gewünscht gerne auch Hilfestellung bei der Vorbereitung!

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
