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.

The Moody Comedy Show is an interactive stand-up experience where the audience sets the tone! Just like in life, we all have different moods—happy, angry, excited, or maybe just “meh”—and comedians are no different. Each performer will embrace their mood on stage, delivering jokes that match their vibe, whether they’re feeling upbeat, frustrated, or existential. But that’s not all—you get to join in too! Audience members will write down their mood, and we’ll pull from a hat, riffing on your emotions in real-time. It’s a comedy show that evolves with the energy in the room https://www.eventbrite.de/e/moody-comedy-showcase-tickets-1276031276899?aff=oddtdtcreator

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

Most people still use AI like a search box: type one question, get one answer, repeat. But the next step is AI agents: systems that can take a goal, break it into steps, use tools, remember context, and produce useful work for a human to review. In this beginner-friendly session, we’ll demystify what AI agents actually are — without hype or jargon. We’ll walk through practical examples of how agents can help with research, planning, writing, coding, operations, and personal productivity. We’ll cover: * What makes an AI “agent” instead of just a chatbot * How agents break tasks into steps * Where agents are genuinely useful today * Where they fail, hallucinate, or need human review * How to design simple AI workflows for your own work * A live demo of an AI agent-style workflow from start to finish No coding experience required. This is for anyone who wants to understand where AI tools are going and how to use them more effectively right now. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

Welcome to Drunken Philosophy, a casual, curious, social discussion club. Come grab a drink and a seat at The Oracle. **Optional topic for this meetup: Where is everybody?** In 1950 the physicist Enrico Fermi was talking about aliens over lunch and asked a question that still has not gone away: if the universe is so vast and so old, and even a fraction of those billions of stars have planets, where is everyone? By the numbers the galaxy should be crowded with civilizations. Instead we look up and hear silence. That gap between "they should be everywhere" and "we see no one" is the Fermi Paradox. One of the most unsettling answers is the idea of a **Great Filter**: somewhere on the road from dead chemistry to a galaxy-spanning civilization, there is at least one step that is almost impossible to get past. Maybe the filter is behind us. Maybe life starting at all, or simple cells becoming complex, or intelligence ever evolving, is the freak accident, and we already cleared the hard part. Or maybe the filter is ahead of us, and advanced civilizations reliably wipe themselves out before they spread. Here is the part that messes with people. If we ever found life somewhere else, even pond scum on Mars, most people would call it the greatest discovery in history. But it might be the worst possible news. It would mean life is common, the early steps are easy, and the hard step is still in front of us. So the eerie silence overhead might actually be the best sign we could ask for. **Questions to wrestle with:** * Is it better to be alone? Would you rather we find alien life and learn we are not special, or find nothing and quietly improve our odds of surviving? * Where do you bet the filter sits, behind us or ahead of us, and why? * If it is ahead of us, what is it? Nuclear war, climate collapse, AI, something we cannot even picture yet? And can we do anything about a filter we cannot see coming? * Does any of this change how you live, or how humanity should be spending its time and money right now? As always the prompt is optional. Come for the conversation, stay for the drinks, and bring your own questions.
