Join us for chill **indoor** 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. We play in domes that are heated up to at least 15C. 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.

Curious what we do? Check our [Instagram](https://www.instagram.com/filmmakersandmovienerds/) ♥️ Would you like to meet some like-minded filmmakers? Start a project? Or do you need help with a movie you are currently working on? Are you new in the city and you'd like to meet people tinkering with movies? **Then you should join us!** We meet every Sunday. It’s important to us that we get to know each other in person. To create a community of connected people, work, learn and grow together. For film making you need a crew of reliable people with a positive can-do-attitude. This is the place to find them. Together, we will talk about these topics: * What you are currently working on * What you need help with * What would you like to help with * What you you would like to learn This is event is great for: * filmmakers * movie nerds * writers * camera operators * editors * actors * sound recorders * composers * gaffers * producers We are limiting the amount of people, so we can have a structured introduction and discussion. After that we get together loosely with some drinks and chats. And then we mostly go for dinner with a couple of us. **Important information**: *To sustain and grow this amazing community, we started a member contribution that is due every month. The money we collect is used solely for the purpose of the community. Of course you can come once or twice without contributing to check us out!*

Hi everyone, join us on Sunday, March 1st 2026, 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

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.
