**Step right up for a fortune-telling experience that's barely accurate, but definitely unforgettable.** Magdalena, the "fortune teller", combines a crystal ball, questionable predictions and a healthy dose of dark humour in a show that's as absurd as it is entertaining. Described by the 'Scotsman' (top newspaper in the UK) as 'unexpected, clever, ridiculous but great stuff, crystal ball and all', this interactive comedy has left audiences worldwide laughing and wondering what just happened. Some say it's life-changing, others call it pure nonsense-but no one escapes without a few laughs, some spirit summoning and answers you probably didn't want. **Sold out run in Edinburgh Fringe Festival 2025** Reserve your seat for just €2, and at the end of the show, you decide what it was worth (suggested contribution: €10-15). Reservations are held until 10 minutes before the show starts. This is a paid show—you just get to choose how much to pay. **Make sure to reserve your ticket [HERE](https://www.eventbrite.co.uk/e/01-accurate-english-comedy-night-tickets-1975608368813?aff=meetup)**

Wherever you come from, you’ll find a place where you can feel at home. Our worship is **traditional and liturgical**, rooted in the rich patterns of the Christian church and easy for both Protestants and Roman Catholics to enjoy. We celebrate **Holy Communion every Sunday and every festival day**, and all baptized Christians are welcome at the Lord’s Table. ACB is an **extraordinarily diverse congregation**, with members from around the world. On any given Sunday you’ll find long-time Berlin residents, young adults, teenagers who attend on their own, families with children, seniors, and many visitors and tourists passing through the city. Our community is known for its **warm and friendly fellowship**—it’s one of the things people talk about most after visiting. Some folks dress formally and others show up in jeans and sneakers; we sit side by side without judgment. **Come exactly as you are.** Most importantly: **our welcome is for everybody—EVERYBODY.** If you’re looking for a church home, a place to pray, just looking to connect, or simply a peaceful hour of worship during your travels, you’re invited.

This group is for everyone who is interested in drawing portraits! For me, drawing has been a wonderful way to gain a new perspective on the world and the people within it. Whether you are just starting out or have been drawing for ages — all levels are welcome :) How it works: 1\. We meet at The Castle pub in Mitte and do short sittings of 15 minutes for each other\. The first sitting is divided into 3 warm\-up sketches\, 5 minutes each\. 2\. Before we start\, everybody writes their name on a blank card \(provided by the organizer\); these cards are then used to randomly pick the model every 15 minutes\. 3\. Usually we do 8 sittings\, with a 15\-minute break in the middle \(so after 4 sittings\, or 1 hour\)\. -> The participation is free, but it is expected that everybody orders something from the bar to support the lovely location. Get out your pencils and let's start! Please bring your own art supplies!

We meet and sketch each other in Berlin. This is just an art gym that we also exercise our social skills. Afterwards usually we go for lunch as a group. **How Does It Work?** This event is simple, we meet and sketch each other doing portraits. Most of the participants use pencils or watercolors. Main aim is to socialize while we draw. There will be plenty of time to talk and get to know each other. We have to mention that this event is suitable for all levels. Many have started to draw in our event actually. **Structure** A. Warmup Phase: We pose to each other for 1 minute. B. Main Phase: We pose to each other for 10 minutes. C. Showcase Phase: We show some of the drawings we did to each other. **Who We Are** Creative Sessions is an art events group located in Berlin. **Is it Free?** The event is free of charge. It is advisable to get a drink though. This is a cafe, we need to have at least half of the people on each table with a drink. They accept only cash and most hot drinks cost from 2.50 to 3.50. **How to help or donate?** The event is provided for free but many people help this be a regular thing. We also need people to volunteer and help for minor tasks like the serving of the drinks or cleaning up. Just send us a message. If you want to donate and keep this event from happening, via Paypal to the host (Miltos) : https://ko-fi.com/miltosthings/ **Art Materials?** Bring your own art materials. **Our Instagram Profile** Follow us on instagram @icreativesessions Use the hashtag #icreativesessions on your post description there to find out drawings from the event!

**Google Analytics Alternatives** Is it finally time to make the switch away from Google Analytics? Two-and-a-half years ago Jason Packer asked this question at Columbus Web Analytics Wednesday. Since then: Google’s Universal Analytics has been sunset, we’ve changed our name to Columbus Data & Analytics Wednesday, and Jason has released two editions of his book “Google Analytics Alternatives”. Fresh off the release of the 2nd edition of his book, we thought it was time to re-open this conversation. While people love to complain about it, GA’s market share has remained relatively constant (at least in the United States). Why is that? You won’t find any complaints about GA4 in this talk, but rather an overview of what’s currently available in the market and how to frame your decision-making process. We’ll also be giving out some free copies of Jason’s book! So even if you’ve got a “GA4Lyfe” tattoo (no judgement), there’s free books to go with the free pizza and beer.

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.
