RSVP on Luma: https://luma.com/h4xm63a4 Silent Reading / Creating Club is a gathering for people who enjoy focusing together in public. Bring a book, a notebook, a sketchpad, knitting needles — whatever you’d like to spend a quiet hour with. All projects and all participants are welcome. ​This year is about creating more — quietly, consistently, imperfectly — and shaping environments that support that. If you’re building something of your own, you’re especially welcome here. ​We’re building a community of readers and creators who value depth, presence, and shared silence. The magic isn’t just in the quiet hour — it’s in the people who return and make it feel like a familiar room. ​(Please RSVP “yes” only if you can make it, so we can save a seat for you and others on the waitlist.) ​This quiet ritual unfolds at **W66 Café**. ​There’s no entrance fee, but please order at least one item from the café and don’t bring outside drinks 🙂 ​No assignments. No pressure. No productivity race. Just a shared hour of intentional silence, followed by relaxed conversation. 🕰 Our Agenda ​**10:30 – 11:00** Arrivals, ordering drinks/food, light social time ​**11:00 – 12:00** The Great Quiet Hour (Read. Write. Sketch. Code. Think. Sit.) ​**12:00 – 12:30** Optional socializing — share what you were reading or creating, or simply continue in quiet focus. ## **​🏡 House Guidelines** ​To keep this space calm and welcoming for everyone: ​• Silence during the focus hour (no calls or conversations) • Phones on silent mode • If using a laptop, please avoid meetings or audio — headphones welcome • Arrive before 11:00 if possible to minimize disruptions

We will start the first writing session at 11:15. **For space reasons, we are limited to a certain number of attendees, so please update your RSVP if you can't come**. We often have a large waiting list, and not updating your RSVP or not showing up if you do RSVP yes means that others miss out. We also ask that if you do change your RSVP, do it with reasonable notice. Thanks! We typically take over all of the cafe, but try to share tables if you can to allow space for other customers.

In between sessions, we have a Telegram chat: https://t.me/joinchat/ERW3pxD5kfELGeWs9SUhjw For more information, visit [https://shutupwrite.com](https://shutupwrite.com/).

A small NEXUS gathering built around movement rather than discussion alone. This is for high-bandwidth Mavericks who spend most of their time in conceptual thought and need some physical counterweight. Why bouldering? Because it’s deliberate: short problems, full focus, and immediate feedback. You’re on the wall, solving something tangible. The mental noise drops instantly! Conversations happen naturally in between climbs. No pressure, you move at your own pace. Some exchanges stay light. Others go deep. Both are fine. This is not about athletic achievement. It’s about presence, recalibration, and being around people who don’t require you to shrink or translate yourself. Come as you are. Try some bouldering problems. Rest when needed, and engage where it makes sense. **Bring comfortable clothes and climbing shoes if you have them (rentals are available at the gym).** *Registration equals commitment. If you sign up, you show up. Read the group description first and decide consciously. For context about NEXUS, visit our* ***[website](https://thenexusformula.com)*** *and* ***[newsletter](https://news.thenexusformula.com)****.*

**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-1980718239574?aff=meetup)**

**Playfight Queerfight** with **Playfight Collective \(LoveDragon \| Sue\)** for **GBTQ men\*** **[Book a Ticket](https://wearevillage.org/shop/playfight-ritual/w10-2026/)** **Member: 15 €** **Non Member: 25 €** Das Playfight-Ritual bietet einen sicheren Raum für queere Menschen, um sich in einer Gemeinschaft körperlich zu begegnen. Es findet in Form von Einzelbegegnungen statt, bei denen sich die Kommunikation hauptsächlich auf die Körpersprache und weniger auf den verbalen Ausdruck stützt. Das Ritual kann von einem Tanz mit minimalem Körperkontakt über gemütliches Kuscheln und spielerisches Herumrollen bis hin zu energiegeladenen Kämpfen reichen, bei denen Kraft und Beweglichkeit erprobt werden. Jeder Playfight wird von den beiden beteiligten Personen bestimmt und kann jederzeit beendet werden durch ein Wort oder durch einen Doppelklopfer. Bevor das eigentliche Ritual beginnt, gibt es eine Aufwärmphase und eine Erklärung der Regeln. **Hinweise** Trage bequeme Kleidung, in der du dich frei bewegen kannst. Lange Hosen sind ratsam, um Verletzungen an den Knien zu vermeiden. Auf Schmuck sollte verzichtet werden. **Sprache**: Je nach Bedürfnissen der Gruppe werden wir Deutsch und/oder Englisch sprechen. **Kosten**: Diese Veranstaltung zählt zu den zwei kostenfreien Veranstaltungen pro Monat für Mitglieder. **Member werden**: Als Mitglied unterstützt du nicht nur unser Projekt, sondern du erhältst gleichzeitig monatlich Zugang zu zwei kostenfreien Veranstaltungen. Mehr Infos **[hier](https://wearevillage.org/mitgliedschaft/).** The Playfight Ritual is a gathering that provides a safe space for queer individuals to connect physically within a supportive community. It takes the form of one-on-one encounters, where communication relies mainly on body language rather than verbal expression. The ritual can range from a dance with minimal physical contact to cozy cuddling and playful rolling around, or even energetic fights that explore strength and agility. Each playfight ‘belongs’ to the two individuals engaging in it and can be ended at any time by a word or by double-tapping your partner or the floor. There will be a warm-up phase and an explanation of the rules before the actual ritual starts. **General information** Wear comfortable clothes in which you can move freely. Long trousers are advised to avoid mattress burns on your knees. Jewellery is not recommended. **Language**: We’ll speak English and/or German, depending on the needs of the group. **Cost**: This event is one of two free events included each month in the membership programme. **Become a member**: As a member, you not only support our project, but you also get access to two free events every month.

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.

This is not an event, but an announcement that we are accepting new members.

# **Band and caller TBA** Beginner lesson at 1:30, regular dancing begins at 2:00 pm NOTE THAT WE ARE TEMPORARILY DANCING IN THE AFTERNOON INSTEAD OF EVENING. Dance with us in the afternoon then you can still go out in the evening! **Sponsor: All Soles Contra and Square Dancing, First Unitarian Universalist Church, 93 W. Weisheimer Rd., Columbus OH 43214** WHAT IS CONTRA DANCING? Picture the Grand Ball scenes like you’ve seen in period films such as “Pride and Prejudice”, where the dancers are lined up in long lines, across from each other. That’s English Country Dancing, the predecessor of contra dancing. Now, add moves like “swing your partner” and “do-si-do,” like you’ve seen in square dancing. Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alá “Riverdance.” Finally, set the whole scene down in the middle of Woodstock, with a hip, groovy atmosphere, a bit of tie-dye, and hints of counter-culture attitude. THAT’s Contra Dancing! Wear cool and comfortable clothes (you will get warm) and clean shoes that won't mark up our nice wood floor. Be sure to come for the beginner's lesson from 1:30 - 2:00, followed by dancing 2:00 - 430. All dances are taught; we will help you learn! Beginners always welcome, no need to bring a partner. Cost is $10.00 adults, $5.00 ages 12-26. Under 12 free. Free parking in church lot. Please bring your own refillable water bottle.
