**Agenda of the evening:**
**Welcome and Introductions:** The Toastmaster of the Day (TMOD) often opens the meeting, who welcomes everyone and introduces the meeting's theme or agenda. The TMOD also introduces the key roles and functionaries for that session.
**Prepared Speeches:** A significant portion of the meeting is dedicated to prepared speeches. Members working through various projects in the Toastmasters education program deliver speeches based on their chosen projects. Each speech is evaluated by a designated evaluator who provides feedback on strengths and areas for improvement.
**Table Topics:** Table Topics is a segment where impromptu speaking skills are tested. The Table Topics Master presents a series of short, unprepared speaking challenges or questions, and members or guests are invited to come to the podium and give a brief, improvised response.
**Evaluations:** Following the prepared speeches and Table Topics
segment, evaluators provide constructive feedback to speakers. These evaluations focus on content, delivery, body language, and time management. The goal is to help speakers improve their speaking skills.
**Reports and Functionary Roles:** The meeting may include various functionary roles, such as the Timer, Grammarian, Ah-Counter, and others, who report on their observations and contributions to the session. These roles help members improve their language and time management skills.
**General Evaluator:** The General Evaluator provides an overall assessment of the meeting, highlighting what went well and offering suggestions for improvement. They may also evaluate the evaluators' performance.
**Awards and Recognitions:** Toastmasters sessions often conclude with awards and recognitions, including the Best Speaker, Best Evaluator, and Best Table Topics Speaker. These awards encourage members to strive for excellence in their speaking and leadership abilities.
**Closing:** The meeting concludes with closing remarks from the Toastmaster of the Day, who may express gratitude to participants and encourage them to continue their Toastmasters journey.
**Networking and Socialising:** After the formal meeting, members and guests often have the opportunity to network, socialise, and discuss their experiences in a more relaxed setting.

Episode 3 of the 2026 Edition - The longest Kotlin night of the year
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:**

**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.

Customize the IDE: Building Extensions for Visual Studio Code - Alan Barber
**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you.
The building address is 4450 Bridge Park
The entrance is 6620 Mooney St, Suite 400
You will need to scan your ID at the door to get a visitor badge.
**Abstract**
*Customize the IDE: Building Extensions for Visual Studio Code*
Visual Studio Code is one of the most widely used development environments today, and much of its flexibility comes from its extension ecosystem. 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.

Round 1 - (7 secs max):
* Your name
* What you're working on

Round 2:
* Community events you wanna plug. If none, that's cool too.
