**⭐ DOORS OPEN AT 19:30. PLEASE ARRIVE BEFORE 8PM! ⭐** The Creative Code Stammtisch is a casual show-and-tell for artists, makers, designers, coders, performers, learners and anyone interested in the use of computing skills for artistic expression. The event is free and open to all, regardless of age, origin, gender or experience. Beginners and first-timers should feel especially welcome! You don't have to be a coder yourself 😃 HOW TO FIND US? Find Prachtsaal Studio by crossing the courtyard next to Cafe Augusta on Jonasstr. 22, 12053 Berlin. WHAT SHOULD I EXPECT? We start with quick introductions, then open the floor to anyone who wants to present something. There are usually around six 10-minute slots available, plus time for questions from the audience. First-timers are encouraged to share their work. Topics range from net art to computational design and interactive installations all the way to wearable electronics or generative poetry. If you’re wondering whether your own project might fit, take a look at the [Stammtisch archive](https://creativecodeberlin.github.io/Stammtisch/) to see what others have shared in the past. This event is *not* just for coders! New-media artists and anyone working with technology in their art are very welcome to share. If you enjoy art and/or technology, you’ll likely have a great time, and maybe even learn something new! BEGINNERS WELCOME!

**18:00!** Join us for chill outdoor beach volley! 🏐 ☀️ 🏖️ 🍻 This event is for everyone who enjoys chill games and is not a *complete* beginner (A1.5+). We play 3v3 (or 4v4) with beach rules. There are no trainers at this event. Register via [the simultaneous event](https://www.meetup.com/berlin-volley/events/) for higher-level 2v2 matches (F1+). After playing, you can join us for socials with drinks and snacks at the bar area. We often play a social deduction game, which you're also welcome to join. It's recommended that you come 10 minutes early so you have time to change and find the fields. If it is your first time, 15 minutes might be even better. You can join whatever court you like and move between courts during the event. We self-organize, so once you finish a game, you can start a rematch, mix with another court, or take a break as you see fit. Upon arrival, join the warmup happening on one of the courts.

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
