Most apps don’t fail because of code — they fail because they don’t **make money**. In this live, hands-on session, we’ll build a real iOS app from scratch using AI-assisted (vibe) coding — and **integrate monetization** from the very beginning. No theory. Just a **real app, built step by step**. You’ll see: * how to go from idea to **working app** in under an hour * how to structure a simple product that can actually **generate revenue** * how **subscription models** work in practice (weekly, monthly, yearly) * what makes a **paywall convert** — and what kills it * how tools like **[Adapty](https://adapty.io/)** help you set your monetization right and make experiments! * **paywall experiments** without rebuilding your app This session is designed not only for developers, but also for **vibe coders, indie makers, and founders** who use AI tools to build products faster — even without a deep technical background. **What you’ll walk away with** * a clear understanding of how monetization fits into product design * a real example of a working app with a paywall * practical insights you can apply immediately **Format** * Live coding session (\~60 min) * Short discussion & Q&A **Who should attend** * mobile developers * vibe coders & AI builders * indie makers * startup founders **About the host** Sèrge Koval — iOS/macOS engineer with 17+ years of experience, cybersecurity specialist, and organizer of Luxembourg Vibe Coding workshops. **Stay in touch** After the session, I’ll share a few extra tips, resources, and updates in Adapty's Discord server: [https://discord.gg/jSrPYTXBTN](https://discord.gg/jSrPYTXBTN) There is also a dedicated "🇱🇺 luxembourg" channel! **Notes** The session will be conducted in English. 📍 OFFLINE and ONLINE from Luxembourg City 🗓 May 27\, 2026 \| 18:00–19:30 ⚡️Spots are limited to 500 — register now.

We play short and long-form improv comedy, which includes theater-style scenes, guessing, and group games. **Topics:** *Timing - Location *Participation (Attendees list) - RSVP rules *Improv session format - Who is it for? (Participation requirement) *** Timing** Being on time will help you and everyone. **18h15** \- Doors open *Please take this time to order your drinks/food and settle in.* **18h30** \- Start of the session **Are you late?** Please inform the event host or comment on the event page.

Wait for the session moderator to indicate when you can start participating. ***Location** We have two locations: Monday Sessions: The session takes place on the first floor of The Sister Cafe. Stairs next to the bar. It's the room with a curtain at the door. Wednesday Sessions: At Brussels Beer Poject Rue Antoine Dansaert 188, 1000 Bruxelles *** Participation (Attendee list)** The session is limited to** 12 attendees**. This ensures the session is manageable and everybody gets enough chances to participate. Therefore, only the people on the "attendee list" can participate in the session. **Waiting list**: People on the waiting list should keep an eye on the updates in case someone from the attendees' list drops and you get their spot. It's important for the people on the waiting list also to update their RSVP status if they already know they won't be joining the session. **Do you just want to observe? **In the regular session, we do not have an audience, only participants. Please do not join the session if you do not plan to participate in the games/scenes. If you are unsure about something, please contact the event host. *People on the attendee list are expected to take part.* *** RSVP Rules** *Please update your RSVP status in a timely manner if you can't make it to the session. This applies to people on the **attendee list AND waiting list.** - If you are on the waiting list and know you won't be able to join in case someone from the main list drops, please update your RSVP to "not going". This will give the next person on the waiting list a chance. *Emergencies aside, please update your RSVP status on time. Canceling at the last minute or just 1 hour before isn't helpful. - If we see a pattern from someone not showing up after confirming or last-minute cancellations, we reserve the right to prohibit session access. *Please write a comment if you cancel and your spot becomes available. With this, others will get an extra notification. **Improv Session Format** The session is held in English. The session has three sections: Warm-up, Scene games, and Cool down. **Warmup:** Quick group games are played to break the ice and get the creative juices flowing. **Scenes:** Then we move on to scene games. These are mostly from short-form improv, which can include different games with various gimmicks, like story building, character work, guessing, etc **Cool down:** One or two short group games to end the session. The rules are explained by the moderator before each game. There is no obligation to participate in games you are uncomfortable with. There can be feedback after a game is played. This is so we learn from each other and gain skills and insights. **Tip**: If you are new, pay attention to the regular players when they are performing and notice small details, like how a stage is cleared before a scene, how to enter a scene, and how to collaborate with each other. *** Who is it for?** Anyone interested in improv! We accept participants at all levels, beginners and advanced. This is a great place to start if you are new to improv. The basics will be explained. We only require the "Yes, and...!" spirit! If you are an advanced player and have ideas and games to share and work on, please do let us know. We look forward to welcoming you and doing improv!

Hallo Freunde der deutschen Sprache, wir laden alle, die gern ihr Deutsch üben wollen, zum nächsten Treffen ein! Bei schönen Wetter sitzen wir vielleicht sogar im Garten des James Joyce.

This workshop series is a **follow-up to the ESP32 Robotics workshop**, but with a different concept. Here, there will be no subject set in advance, instead **all participants are welcome to join at any point and at any level, from beginner to expert**. Beginners will be guided though the basics (C programming, how to use measurement tools, soldering, PCB design, etc…) and can get advice on what tools and kits to start with, others can come with their own projects to get help or share some knowledge. ## Requirements * Bring your own laptop (Windows, Linux or Mac) * Any microcontroller/dev kit to develop your project(s). If you are a beginner and don’t know what to buy, come and we’ll find the best starter kit for you ! * A strong desire to learn stuff, good mood and some patience !

Welcome to our weekly event in the upstairs room of The Sister Café, rue Chair et Pain 3, one block from the Grand Place. Please get there early enough to order your drink at the bar first. Thank you! After introductions we will collect questions from the group participants, choose one by voting then discuss it for an hour. Then most of us stay for drinks and bizarre conversations. Past questions have been wide and not confined to academic philosophy: What is a genuine friend? Is social media turning us into emotional zombies? Do we lose some of the experience of things by defining them? Are we driven by sex? Is loneliness a personal failure? Is morality relative? **Crucially, be kind and respectful and generous** in your disagreements; remember how much you personally enjoy someone else proving you wrong before celebrating your cutting counterexamples.

But returning to yourself doesn't always have to be hard work. Anchored by the comforting, rich warmth of ceremonial cacao, we will create a grounding space to help you land safely back in your physical body. From this place of deep, earthy coziness, we’ll use gentle rhythm to invite in a sense of lightness and simple, child-like play. This experience is designed to help you peel back the layers of stress and rediscover your "inner smile"—that stable, quiet joy that lives beneath the noise. If you are ready to shed some weight, reconnect with who you are, and leave feeling lighter, you belong here. ✨ ​This ritual is an invitation to pause, step out of the daily rush, and simply let yourself *be*. While cacao is traditionally known as a medicine of the heart and love, in this space, we will lean into its comforting warmth to help us gently relax and open up. It gently expands our capacity for inner listening, creating the perfect earthy foundation for joy to naturally arise. ​Supported by breath, sound, movement, and community, this ritual offers a safe, grounded space to: * release the physical tension of overwhelm * reconnect with your body in a gentle, nourishing way * embody inner joy—not as an abstract idea, but as a lived experience === [Confirm your your presence](https://hipsy.be/event/213471-connect-to-your-joy-a-full-moon-cacao-drum-ritual) === === ​🌿 What to Expect \| Ritual Flow **🕰️ Timing & Arrival** * **18:30** – Doors open (arrive, settle in, and get comfortable) * **18:55** – Doors close (to ensure a safe, uninterrupted container, no entry after this time) * **19:00** – Ritual begins ​The experience unfolds in a carefully held and progressive way: * **​Welcoming & arrival** Grounding into the space and the group * **​Breathing and somatic practices** To calm the nervous system and prepare the body * **​Guided cacao ritual** Drinking ritual-grade cacao, prepared with intention accompanied by a gentle guided meditation * **​Conscious dance** Allowing insights and emotions to move through the body while connecting to the joy * **​Drum meditation** A deep, rhythmic journey to support inner clarity and emotional release * **​Closing circle** Integration, sharing (optional), and grounding before returning to daily life ​No previous experience with cacao ceremonies, meditation, or dance is required. ​🤎 About the Cacao ​The cacao used in this ceremony is: * ​100% pure, ritual-grade cacao * ​ethically sourced * all ingredients used are vegan * ​prepared slowly and mindfully, with intention for the process and the group ​Cacao is not a psychedelic substance.
