The Language Café is primarily aimed at people who are struggling with their mental health which can make it hard to go to regular courses. We want to create a safe space for everyone to learn and practise without pressure. Everyone is welcome! Please try to be on time so we can all get started together :) We mainly practise on a beginner/lower intermediate level and adapt to everyone's prior level of German. The Language Café will focus on teaching you the most important words and phrases and basic grammar in German. The content of the course is adapted to real life. (everyday life in Germany, dealing with authorities, etc.) We will cover different topics every week and you can join us anytime, since the topics do not necessarily build on each other. The Sprachcafé is for free. \*If you cannot make it please cancel your participation so someone else from the waiting list can join, thank you!\* \| \| \| \|

I’m Lindsey, a senior data scientist working on AI, causal inference, and data products. I’ve built models for fraud detection, uplift modeling, and LLM-based systems—and I care a lot about learning through building, not hype. 📅 When: Saturday, Jan 24 · 9:30–11:30 📍 Where: Torstraße 59, Forward Earth 💻 Bring: Your laptop, an idea—or just curiosity

Hi everyone, join us on Sunday, January 25th, at Castle Mitte for a fun afternoon to connect and discuss MBTI personality, psychology and other interesting topics. Looking forward to seeing you there! Take a test to learn your type: https://www.16personalities.com/free-personality-test https://sakinorva.net/functions Some basic info on functions and type: https://www.verywellmind.com/the-myers-briggs-type-indicator-2795583 https://www.truity.com/blog/beginners-guide-understanding-mbti-cognitive-functions Our group aims to bring together people who are interested in self-development and self-improvement using MBTI and cognitive functions, in order to learn more about the theory and share our experiences with it. Another reason for this meetup is to meet people with whom you might potentially get along really well based on your type. This can lead to meaningful connections :)
Although the meetup is geared towards people who are interested in learning about MBTI theory and using it to improve their lives, our conversations aren’t only about that! We talk about anything and everything. So it's more like a regular social meetup with the aim of avoiding small talk :) 
You can also join our WhatsApp group chat here: https://chat.whatsapp.com/KzEwl2YD5K9F6adO7kvqPO

Hey everyone! I’m organising a co-working + socialising session for all of us who like to work on something (e.g. our own project, freelance or remote work) but don't feel like sitting alone at home. 🙂 To ensure that we have both **socialising** AND **working**, we will be using the so called “Pomodoro” technique: **50min of deep work** (silent), followed by **10min of break** to socialise. Then repeat! If you get into flow, you're also welcome to skip the breaks. It’s an effective way to stay focused - you can read more about it [here](https://en.wikipedia.org/wiki/Pomodoro_Technique). Anyone from any background is welcome, whatever project you are working on or whatever is your personal background. I (the host) speak English and German, so either is fine :-) ——————————————————- AGENDA: * **15min Intro** * Get to know everyone, talk about what you will work on today * **Pomodoro Session** (3x) - *Each Pomodoro session consists* *of...* * ...**50min** of uninterrupted “deep work” (no talking, no interruptions, no phones) * ...**10min** of break: share your progress with others, talk about what you are stuck on etc. * Repeat * Conclude and celebrate your progress Share your progress, socialise and get to know others 😊 ———— We'll be at the Social Hub Berlin (they have a food menu in case you get hungry). The structured part will end at 2:30pm, but you're welcome to stay longer, go for lunch together, or leave earlier. See you there 🩵 **\*\*We'll reserve the long table. Please update your RSVP in advance if you can't attend!\*\***

We will be meeting at Starbucks to learn together. Come with an online class you're already going through or an interest and we will try to connect you with a course where you can learn it. Already have a skill you want to contribute to a Kaggle Datascience competition? We will work on these too! Laptop required :)
