MP(FRI)-Sand Volleyball: BB - Crystal City
***Please read all and make sure you agree before you sign up.***
**Court Type:** Outdoor Sand
**Level:** adv beginners+/intermediate (BB/A)
**Transportation:** Parking will be right by the sand courts, behind the courts, and there is garage parking close to the courts. Metro is the Blue and Yellow Lines.
**What to bring:** at least 3 bottles of water and a ball if you have one.
**MAX:** 10 players per net. (1 Net)
**Restroom:** Restrooms are across the street in the restaurants.
**Host's Philosophy on This Event:**
The purpose of this meetup is to create a fun and supportive environment where we can improve our skills, enjoy competitive games, and connect socially. While we do aim to play seriously and challenge ourselves, the focus is more on growth and enjoyment than simply winning at all costs. That’s why the title doesn’t include “competitive” or “social”—we want a healthy mix of both. This is a space where you won’t be judged for making mistakes, ***but we do expect you to listen to the organizer if they make suggestions or adjustments***. We also expect a mindset geared toward learning and getting better over time. That said, this event isn’t intended for total beginners; an understanding of the game is expected so that everyone can contribute to meaningful and engaging matches. The host holds the right to remove you from the game if they believe that you are at a C level.
**Skill Level:**
1. **If you want to know your level, please see the link below:**

**ATTENDANCE:**
**Player Selection:** Regulars > League Members > Smiley Attendance Ratio\* > Skills (BB>B) > New Members
The host takes attendance very seriously. Please remove yourself from the event (if you can't make it) as early as possible to allow others to join. You will be marked as a ***no-show*** if you don't show up to the event.
One no-show means you will be removed from the group. See the rules below.
**\*The organizers can see the number of times you have attended events vs the times you have dropped out. If your drop rate is more than 50%, you may not be accepted to the going list.**
[Smiley Social Rules](https://docs.google.com/document/d/1HrG35p_0M08leRvCp8XWG3CMkr_GL928XFabl5T6Dvg/edit)
**Q&A**
* Bringing your **dog/cat** is welcome and encouraged.
* *Can I come if I don't know how to play?* No, you may not. Smiley teaches a beginner's volleyball class that you may attend.
* *Can I be late or leave early?* The host expects you to be there **on time** and leave on time. If you need to arrive late or leave early, please let the host know in advance.
* *Can I come even if I am not on the going list?* No, sorry
* Why Max the players at 10 when you can do 6v6? This court is already for 2v2; getting 6 players on each side is overkill.
* How can I become a regular if I don't ever get to attend? You can attend my other events on weekdays/weekends. Show me you have good skills and bring good vibes!

Murder Mystery March Madness
I figured I'd gear this event more towards Murder Mystery games. For starters, I have Deception Murder in Hong Kong, quite the fun social deduction experience 😎
I'll be happy to provide some snacks and light refreshment. Feel free to bring your own snacks, food, refreshment, board games, and/or anything you think will add to the murder mystery vibe!
I'll also have Mortal Kombat 11 and Karaoke available for anyone interested. If enough people desire, I'll happily pool resources to order pizza from the local Pizza Boli's.
Profs & Pints Northern Virginia: Digital Device Detox
[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“Digital Device Detox,”** a guide to breaking free from the addictive and destructive powers of social media and apps, with Jillian Tucker, licensed clinical social worker in private practice, adjunct professor of clinical social work at Columbia University and New York University, and therapist with nearly 15 years of experience in addiction treatment and behavioral change.
[Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/northern-virginia-digital-detox](https://events.ticketleap.com/tickets/profsandpints/northern-virginia-digital-detox) .]
Many of us have had the same experience: We’re trying to get things done and stay focused on the positive in our lives, but we can’t stop looking at a cell phone that tells us that we live in troubled times, that everyone else is better looking and having more fun, and that escape awaits in the worlds of Candy Crush or Pokémon Go.
Maybe it’s time to find effective ways to loosen the grip of that cell phone and rediscover the happiness that comes with using digital devices less.
Join Jillian Tucker, who previously has given several excellent Profs and Pints talks related to mental health, for a crash course on how to restore balance in your relationship with digital devices to ensure they’re simply tools you use rather than instruments through which other people use you.
She’ll start by discussing social and mental-health trends connected to the use of digital devices. We’ll delve into the specific ways that their overuse can be biologically and psychologically harmful and leads to division, depression, anxiety and anguish on an individual and societal level.
Professor Tucker also will look at why digital habits are hard to break, citing neuroscience and what we know about behavioral addiction. You’ll learn the many ways in which devices and apps are deliberately designed to be hard to stop using.
You won’t be urged to just chuck your cell phone, though. After all, such devices can keep you socially connected, be sources of joy and learning, and even save your life if you need to summon help in an emergency.
Instead, we’ll look at effective strategies for reducing digital device use, considering approaches that treat the overuse of such devices as “addiction” but moving beyond them to consider more nuanced ones as well. We’ll explore how to find our core motivation to change and how to carry out a change plan. We’ll consider how those who failed in past attempts to reduce digital-device use can overcome impasses in their effort to change their behavior.
We’ll discuss ways to minimize the feelings of inconvenience and withdrawal that might come with reducing digital-device use, and we’ll discuss strategies for regaining the social skills and reviving the in-person strategies that our device use had compromised. You’ll learn how the same conditioning and power of habit that got us using our devices so much more also can be harnessed to help us use them much less.
You’ll learn how to curate and enhance the positive aspects of digital devices, to help maintain them as a source of connection, joy, humor and learning and keep them from causing you unhappiness or stress. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.)

CBusData: The Fellowship of the Star Schema: Transforming OLTP Data for Power BI
The Fellowship of the Star Schema: Transforming OLTP Data for Power BI
One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again.
We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all.
Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.
Westerville Queer Coffee Meetup

How LLMs Like ChatGPT Actually Work and How to Build With Them
**First meetup of the Columbus AI Engineering group.**
We’ll kick things off with a practical, beginner-friendly discussion on:
**How LLMs like ChatGPT actually work — and how to build real applications with them.**
We’ll cover:
* what’s actually happening under the hood (at a high level)
* why LLMs behave the way they do (hallucinations, prompt sensitivity, etc.)
* how people are building real systems with them today
* where things break in practice
This will be a **short, informal talk (\~15–20 min)** followed by open discussion and Q&A.
Whether you’re an engineer, builder, or just curious about how modern AI systems work, you’re welcome to join.
No slides, no fluff — just real conversation about real systems.
We’ll hang out afterward and get to know each other.
Connected Westerville Night of Networking!
**Connected Westerville Night of Networking** *April Edition: The Introduction Economy*
You've been to the networking events. You've done the small talk. Collected the cards. Forgotten the names. And walked out feeling like you just wasted two hours of your life.
The problem isn't you. It's the format.
Most networking events put you in a room and tell you to figure it out. So everyone defaults to elevator pitches and business talk, and nothing real gets built.
Here's the truth about networking that most people miss: Your network isn't just who you know. It's who thinks of you when they're talking to someone else.
*That's* The Introduction Economy. And it only works when relationships are real.
There's a reason people who come once keep coming back. It starts with seven minutes that feel nothing like networking.
Then we open it up. Free networking. More conversations. More momentum.
This is a room full of corporate professionals, entrepreneurs, business owners, creatives, and career builders in the Westerville and Columbus area. The mix is the magic.
You might never do business with everyone you meet tonight. But someone in this room will think of *you.* **By name**. So, the next time someone needs exactly what you do, you get the recommendation.
**April 14th. RSVP now.**
**When:** Tuesday\, April 14th \| 6:15 PM \-\- 8:00 PM **Where:** Vineyard Community Center \| 6000 Cooper Rd\, Westerville\, OH 43081
