Friday Mafia Session - Social Deduction Game
This event is beginner Friendly. More experienced players are still free to come along. I will explain the rules before the first game at 7:15 so please arrive on time if you're new. The rules may be different than other versions of mafia that you played.

📚 Books & Social 🍸
📚Reading books and discussing them are two distinct experiences! Conversations about books and sharing insights help us better appreciate literature and enrich our lives.
Let's grab a drink (alcoholic or non-alcoholic) and discuss books we're currently reading or have recently enjoyed—whether poetry, fiction, or non-fiction. Bring your physical book or e-reader.
There's no formal structure or agenda—just books and good conversation.💬
It's a perfect place to get book recommendations and rediscover your reading momentum if you've hit a slump. We welcome readers of all backgrounds and interests!
⚠️**Something Happened?**
If something unpleasant happened to you, it may happen to others. Even if it seems minor, don't hesitate to reach out to me.
🔍 **How to find us?**
* When I reach the venue, I'll leave a comment in the meetup where the group is seated. Normally, the booking is in my name, so you can ask the staff for the group.
* If you're unable to find us, leave a comment in the meetup page. I'll be able to guide you.
We highly encourage you to move between tables and strike up conversations with fellow book lovers. These discussions about literature and reading recommendations are often the highlight of the event!
As an organizer, I'm always looking for feedback about the event and suggestions for new events, so feel free to suggest ideas to me. 💡
I look forward to seeing you all! 😊
Social Entrepreneurs and Changemakers Meetup
Social Entrepreneurship Meetup
🌳 As the afternoon light settles over the city and the garden of the Museum of Literature Ireland comes alive with its quiet charm,
we gather at MoLI Café for the meetup —
to dream, to connect, and to create together.
We welcome those who are interested in making a positive difference —
through projects, creativity, entrepreneurship, purpose-driven work,
art, education, or technology.
Whether you have an organization, a plan, or just a quiet impulse to make things better — you're welcome.
The only thing that matters is the desire to make positive change — and to find others who feel the same.
To find your tribe.
\-\-\-
🌀 The format
This is a casual, open meetup — no agenda, no speakers, no pressure.
You can talk about projects, ideas, visions — or simply enjoy being around people
who dream and feel like you do.

Session Abstract
**Data on Fire: A Hands-On Intro to Spark in Fabric**
Curious about Apache Spark but not sure where to start? This hands-on session introduces you to Spark in Microsoft Fabric Notebooks—a powerful and accessible way to process and analyze big data using familiar tools in the Microsoft ecosystem.
We’ll break down key Spark concepts like distributed computing, DataFrames, and lazy evaluation, then show how they come to life inside Fabric’s notebook experience. You’ll see practical demos that cover loading, transforming, and analyzing large datasets—while leveraging Fabric’s modern data stack, including OneLake, Dataflows, and Pipelines.
You’ll also learn how to choose between Spark and pure Python notebooks in Fabric, based on execution needs, data integration, and use case fit.
Whether you're a SQL pro, BI developer, or data engineer, this session will give you the tools and confidence to start using Spark in your own projects—no cluster management required.
\*Please note, that we will be using Microsoft Teams for the online portion of this meeting. You may want to join a few minutes early to ensure you do not have any issues. If you are attending in person, there are large TVs at the office, and you do not need to bring a laptop or use Teams.

In-Person Event: The Answers to Depression & Anxiety
This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them.
Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance".
Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you.
The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life.
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.
Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there.
This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.
