@ Anna Blume - A cozy book swap and chat meetup!
The "classical" bookswap is simple:
* We meet in a café and put the book(s) we brought down on the tables.
* We browse and discuss the books with one another while sipping coffee or hot chocolate, or eating cake.
* We write our names down on any books we’d like to take home (post-its and pens provided).
* At the end of the evening, negotiate any books that are contended and take a new-to-you book home!
Books/happiness shared are books/happiness multiplied! A Bookswap is 10 times better than a Book Club because you can talk about ALL the books instead of just one!
This is a great way to give your books a new home and make room for new books: that book you feel guilty for not having read even though it's been sitting on your bedside table for the last 5 years, the book you liked but didn't love, the book you loved so much you want everyone to read it, the book you somehow own three copies of, that book you absolutely hated even though everyone else loves it, and so on.
Moreover, you will meet fellow readers, get a new book or two, and several book recommendations. We’ve often had readers experience books they wouldn't normally buy and enjoy it.
GROUP EXPECTATIONS for PLEASANT SWAPPING
* Please bring a book! It's not that you bring one you take one, but do try your best to bring something.
* Books stay on the tables, open for sharing, until you are ready to leave so that everyone can have a look. We are notably not first come first serve. Please wait until you are leaving to bag the book.
* If two or more people want the only copy of a book, negotiate. Maybe one of you reads it first and then gives it to the others. Or perhaps they have found another book instead. Or leave it to fate and toss a coin. The best part: now you have found somebody whose taste you can really admire. In any case, please don't walk away with a book with several names on it without letting the others know.
These negotiations are fun and easy, so don't shy away from a book because there's already a name on it, and feel free to put your name on as many books as you find interesting. It's not that you bring one you take one; you may take as many as you can negotiate.
* Political discussions with consent: make sure the people you are talking to would like to have a political discussion with you.
* Please respect this space as first and foremost a community for connecting readers over their love of books and reading, stories, and narratives of all sorts. Please be respectful of tastes and opinions.
* If something is bothering you, please reach out to the organizers, and we'll do our best to resolve it.
* Lastly, don't expect your book back. It will find a new home. If you love it, let it go.
Major LANGUAGES (and genres) of this meetup: English, German, French, Spanish, Italian; Fiction, Non-Fiction, Serious Reading, Light Fun, “classics", Krimis, Booker winners, Sci-Fi, Fantasy, Self-Help and more. You never know who can read what languages, and there's no accounting for taste.
We are a delightful and international group of readers.
We look forward to swapping with you!
Shuffle/Cutting Shapes Class - Combos
This is a **shuffle**/**cutting shapes** class for beginner and intermediate shufflers where we'll be working on **combos**.
**Beginner shufflers** will get the chance to learn some basic steps and practice them stress-free in short combos to various speeds.
**Intermediate shufflers** will learn to vary these basic steps with additional leg and arm movements, learn to combine them in new ways, keep practicing their foundations, and try to integrate the new combos into their freestyle.
If you're a complete beginner and wanna try some basic moves by yourself before the class, you can watch this video on Youtube: https://www.youtube.com/watch?v=5xOAJA598uk But you don't have to - don't worry and come just by!
**What you need to bring with you:**
**Shoes**: If you'd prefer not to shuffle in socks, please bring a pair of dedicated clean athletic shoes with white soles.
**Water**: because Shuffling is like an intense cardio workout :)
**Fee**: 10€ (in cash or paypal after the event) to cover the cost of the rent, because we're not doing it for profit.
Teacher: Ina
P.S. You're welcome to join our Telegram group where we share choreos, combos, music, etc. https://t.me/joinchat/73TM5UceauA5YmQy

0.1% Accurate- English Comedy Night
**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.

Mavericks Bouldering — A Casual Climb & Hangout in Berlin
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)****.*
CLOSER x-dance | Inviting your Erotic Pulse via a 5Rhythms Dance Journey
**✧ FOR YOU ✧**
Maybe you’re curious about eroticism as life force —
about playing with sensuality, clothing, and aliveness in a safe(r) space. Maybe you just love good music and want to dance outside the club.
CLOSER x-dance is for all who want to explore the meeting of movement, creativity x life force energy.
CLOSER x-dance is open to all, creating a safe(r) space for different horizons, sexual orientations and experiences.
***No previous experience required.***
**✦ WHAT IS CLOSER x-dance ✦**
CLOSER x-dance is a dedication to unshackling any chains that teach us to separate our inherent er-t\*c aliveness from the rest of ourselves. It is an invitation to embrace the sensual when it arises, to grant permission to our emotions, and to move with creative play in a spontaneous movement journey.
Guided by an eclectic wave of sound and inspirational prompts,
you’ll move through the 5Rhythms — five life energies that rise and fall like a wave.
✺ **Three ingredients shape each journey** ✺
✺ Celebration of you - Nothing to get "right"
✺ Invitations - Follow what feels true for you
✺ Presence - Dance becomes a meditation in motion

CBusData - Discover the Power of Window Functions
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.
COUNT RMH Housewarmer Volunteering (Ronald McDonald House)
Some trained COUNT volunteers work together once a month at RMH (http://www.rmhc-centralohio.org/volunteer.php) as Housewarmers (usually on the 1st Sunday from 1 – 5 PM). Some schedule other shifts at their convenience. You may try this out with less fuss by following a "Fast track" or go through the normal process.
Fast track
• Arrange a time to shadow a COUNT volunteer. Call Dave Nohle at 614-268-9558 (cell).
• Show up and try it out.
• Complete application, etc. later.
Normal process
• Complete an online application (http://rmhc-centralohio.org/volunteer/).
• Attend orientation in advance.
• At orientation you will complete forms agreeing to keep family/patient info private and allowing a background check and tour the facility.

RMH Housewarmers volunteer at least one four-hour shift a month. All Housewarmers must complete an application and agree to a background check before they can be full fledged volunteers.
Free In-Person Meeting: Healing from Trauma and Past Betrayals
This is a free, in person meeting.
Burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse.
Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well.
Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship.
Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action?
Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life: human relationships!
Break free from self imposed limitations
Here we will discuss:
• How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes.
• Why and how do the negative emotions of others affect you?
• Why is my partner withdrawing and what can I do about it?
• Why do we sometimes feel compelled to hurt the ones we love?
• Fights & arguments - what's really behind them?
• What underlies “corrosive criticism” or the need to invalidate self or others?
• How one can stably change one’s outlook on life so they can affect positive change?
• Where do compulsive destructive behaviors come from and what can be done about them?
• How to form closer bonds & keep growing the relationships with the people you care about?
• How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career?
Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general.
Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person.
Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life.
We look forward to having you join us!

Bad Girls Book Club March 2026
**Our March pick is *God of the Woods* by Liz Moore.**
**This month’s novel is an award-winning literary mystery that blends family drama with psychological suspense. It explores women’s voices and relationships while delivering an exciting, eerie, and deeply suspenseful story. The book is 576 pages in print or 14 hours and 35 minutes on audiobook.**
Early morning, August 1975: a camp counselor discovers an empty bunk. Its occupant, Barbara Van Laar, has gone missing. Barbara isn’t just any thirteen-year-old: she’s the daughter of the family that owns the summer camp and employs most of the region’s residents. And this isn’t the first time a Van Laar child has disappeared. Barbara’s older brother similarly vanished fourteen years ago, never to be found.
As a panicked search begins, a thrilling drama unfolds. Chasing down the layered secrets of the Van Laar family and the blue-collar community working in its shadow, Moore’s multi-threaded story invites readers into a rich and gripping dynasty of secrets and second chances. It is Liz Moore’s most ambitious and wide-reaching novel yet.
Data & Analytics Wednesday - Google Analytics Alternatives
**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.
