Claude Code with Unity
A session on using Claude Code, Anthropic's AI coding agent, in real Unity development. We'll cover what coding agents are, where Claude Code fits, and how to apply it to an actual game project.
The format is presentation-style, with live demos and time for questions throughout. After brief scene-setting on coding agents and what makes Claude Code distinct, we'll go problem-driven: demoing it live on a released Unity game and introducing each feature as a solution to a problem we hit.
What to Expect:
* An intro to coding agents and where Claude Code fits
* A live demo on a real Unity project
* Key features as solutions to real problems: 𝖢𝖫𝖠𝖴𝖣𝖤.𝗆𝖽, context management, hooks, skills, subagents, and MCP
* Unity-specific pain points, including Domain Reload and MCP caveats
* Putting it together
All experience levels welcome. Food and drinks provided.
*Note: meetup topics may change — check back for the latest details.*
Bad Girls Book Club June 2026
**Our June novel is: *The Eights* by Joanna Miller**
**This month’s novel is set during World War I. It’s a 20th-century historical fiction story about friendship and war, with coming-of-age elements and a slightly haunted tone. The book is 384 pages in print and 10 hours and 9 minutes on audiobook.**
Oxford, 1920. For the first time in its one-thousand-year history, Oxford University officially admits female students. Burning with dreams of equality, four young women move into neighboring rooms in Corridor 8. Beatrice, Dora, Marianne, and Otto—collectively known as The Eights—come from all walks of life, each driven by their own motives, each holding tight to their secrets, and are thrown into an unlikely, unshakable friendship.
Dora was never meant to go to university, but, after losing both her brother and her fiancé on the battlefield, has arrived in their place. Politically-minded Beatrice, daughter of a famous suffragette, sees Oxford as a chance to make her own way - and some friends her own age. Otto was a nurse during the war but is excited to return to her socialite lifestyle in Oxford where she hopes to find distraction from the memories that haunt her. And finally Marianne, the quiet, clever daughter of a village pastor, who has a shocking secret she must hide from everyone, even her new friends, if she is to succeed.
Among the historic spires, and in the long shadow of the Great War, the four women must navigate and support one another in a turbulent world in which misogyny is rife, influenza is still a threat, and the ghosts of the Great War don’t always remain dead.

Walk & Talk About Life's Big Questions
[The Board Walks](http://www.theboardwalks.com/) are for curious people who love deep conversations.
If that sounds like you, **bring a thoughtful topic** and join us for a 5-mile walk (10,000+ steps!).
**HOW IT WORKS**
**Step 1: Bring a topic**
Before you arrive, think of **one** topic you want to explore. A question. A thought that's been on your mind. An obsession you want to geek out on. This is your ticket to the event.
**Step 2: Circle up & share**
We gather in a circle. Your friendly walk host gives a speech to set the tone. Everyone shares: your name, what you're grateful for, and your topic. That's it. 60 seconds.
**Step 3: Walk, talk & float**
We walk 5 miles. You naturally drift into conversation with 2-3 people at a time, pulled by topics that spark your curiosity. When you're ready to move on, just say: "I'm going to float!"
**Step 4: Feel more alive**
Two hours flies by. You're back where you started — but you feel different. More alive. More energized. More connected to yourself and others. That's why regulars join 20+ times.
*For more details, read our [Orientation Guide.](https://www.theboardwalks.com/orientation)*
**HOW TO BRING A GREAT TOPIC**
A great topic = something you're genuinely curious about.
Recent topics include:
* "What are you passionate about right now?"
* "What makes a good friend?"
* "What's a belief you used to hold that you've completely changed?"
* "How do you want to be remembered?"
* "What would you do if money wasn't a factor?"
Think of your topic like the dish you're bringing to our conversational potluck. If everyone brings an A+ dish (i.e. energizing, uplifting, expansive), we'll all walk away feeling lighter and brighter.
**WHAT TO EXPECT**
This isn't a fitness event with casual chitchat. It's a walking think tank where we explore life's big questions together, beyond small talk. *If you're looking for light banter or a standard networking event, this probably isn't the right fit.*
But if you crave depth, genuine connection, and conversations that make you feel alive? You'll love it here.
**FAQ**
* Wear casual athletic attire and sneakers. It's a long walk!
* We have multiple first-timers at each event. We work hard to create a welcoming, inclusive, clique-free space.
* We welcome people of **all** ages, backgrounds, and industries who align with the [intention](https://www.theboardwalks.com/ground-rules) of this space.
* Rain or shine, we've been out here nearly every week since July 2022. If the event is cancelled, we'll let you know.
* Dogs, babies in strollers, parents, and friends are welcome — please text/email them the event link so they can RSVP and prepare a topic!
**LOGISTICS**
* If you'll arrive over 10 minutes late, we suggest skipping the event. It's hard to find us once we start walking, and your host can't answer messages during the event.
* This walk is designed for everyone to *move together at the same steady pace* (about 20 min/mile). This format works best when the whole group moves in unison. If you have mobility limitations, we kindly encourage you to find an event better suited to your needs.
* Read our [Orientation Guide](https://www.theboardwalks.com/orientation) for full details.
* If you enjoy the event, send **[this](http://www.theboardwalks.com/)** to a friend or sign up for our **[newsletter](https://theboardwalks.beehiiv.com/)**. We're in multiple cities with more on the way. 🤠👋
**IF YOU WANT TO GO DEEPER...**
[The Board](https://stan.store/ellebeecher/p/the-board) is the next step: a high-trust collective for renaissance people devoted to creating, connecting, and building lives that light us up.
* This is a global HQ for people who crave big talk, deep connection, and dream collaborations with people across industries. If the walks feel like a spark... The Board is the fire. Apply [here](https://stan.store/ellebeecher/p/the-board).

Efficient Region-of-Interest Detection with Guidance
**Abstract:** Motivated by the challenges of detecting extremely rare failures in sophisticated circuit design specifications, we study the problem of efficiently identifying multiple disjoint regions of interest (ROIs) — regions of a continuous, high-dimensional parameter space where a complex, expensive-to-evaluate target function falls below or above a pre-specified threshold. We reframe this problem as a Bayesian sequential decision-making problem and, more broadly, as an instance of strategic agent behavior in continuous spaces: an agent that must allocate a hard evaluation budget intelligently, updating its belief about the unknown function after each observation and choosing the next query to maximize coverage of all disjoint failure regions rather than convergence to a single optimum.
This is a *hybrid* event. To attend online, join us on Zoom here at 6pm:
[https://iit-edu.zoom.us/j/89379230295?pwd=NdETyE5sdYuSrvsrBZXSBFkUESBVkg.1](https://iit-edu.zoom.us/j/89379230295?pwd=NdETyE5sdYuSrvsrBZXSBFkUESBVkg.1)

Columbus Code & Coffee 87 @ Improving
Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you!
**What to Expect at the Intro Circle**
\~\~\~\~\~\~\~\~\~\~\~\~\~
Near the beginning of the event (1:30 pm), we do a standup:
* Organizer announcements, updates, and logistics
Round 1 - (7 secs max):
* Your name
* What you're working on
* What you can help others with
Round 2:
* Community events you wanna plug. If none, that's cool too.
Round 3:
* Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool.
After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!
Drunken Philosophy: Where Is Everybody? The Fermi Paradox and the Great Filter
Welcome to Drunken Philosophy, a casual, curious, social discussion club. Come grab a drink and a seat at The Oracle.
**Optional topic for this meetup: Where is everybody?**
In 1950 the physicist Enrico Fermi was talking about aliens over lunch and asked a question that still has not gone away: if the universe is so vast and so old, and even a fraction of those billions of stars have planets, where is everyone? By the numbers the galaxy should be crowded with civilizations. Instead we look up and hear silence. That gap between "they should be everywhere" and "we see no one" is the Fermi Paradox.
One of the most unsettling answers is the idea of a **Great Filter**: somewhere on the road from dead chemistry to a galaxy-spanning civilization, there is at least one step that is almost impossible to get past. Maybe the filter is behind us. Maybe life starting at all, or simple cells becoming complex, or intelligence ever evolving, is the freak accident, and we already cleared the hard part. Or maybe the filter is ahead of us, and advanced civilizations reliably wipe themselves out before they spread.
Here is the part that messes with people. If we ever found life somewhere else, even pond scum on Mars, most people would call it the greatest discovery in history. But it might be the worst possible news. It would mean life is common, the early steps are easy, and the hard step is still in front of us. So the eerie silence overhead might actually be the best sign we could ask for.
**Questions to wrestle with:**
* Is it better to be alone? Would you rather we find alien life and learn we are not special, or find nothing and quietly improve our odds of surviving?
* Where do you bet the filter sits, behind us or ahead of us, and why?
* If it is ahead of us, what is it? Nuclear war, climate collapse, AI, something we cannot even picture yet? And can we do anything about a filter we cannot see coming?
* Two principles pull opposite ways here. The principle of mediocrity (the Copernican principle, Sagan's "no privileged place in the universe") says we are ordinary, so what happened on Earth probably happened everywhere, which makes the silence scream louder. The anthropic principle says of course we find ourselves somewhere life was possible, since we could not observe anything else, so our being here may say almost nothing about how common life is. Which lens do you trust, and does the silence still demand an answer once you account for observer selection?
* And if we did confirm life out there and had to accept we are not special, what would that do to belief in a higher power, and would shedding (or keeping) that belief help or hurt our odds of pulling together as one species?
* Does any of this change how you live, or how humanity should be spending its time and money right now?
As always the prompt is optional. Come for the conversation, stay for the drinks, and bring your own questions.
Stop Guessing: A Product Person's Guide to AI Adoption
## 🤝 Host Information
A co-hosted event by ProductTank Columbus & Women in Product Columbus
💡 About the Workshop
AI adoption is stalling across organizations — not because of a lack of motivation or tools, but because it's fundamentally a behavior design challenge.
This hands-on workshop applies proven Behavior Design models and methods to help you move from a vague organizational wish to boost AI adoption to 3-5 concrete, testable interventions you can act on starting tomorrow.
Whether you're a product manager, on a product team, or just someone trying to get AI to actually stick at work, you'll leave with a clear picture of what's worth focusing on, what to ignore, and how to drive real, sustained adoption — no guesswork required.
🛠️ What to Bring
Laptop: Fully charged and ready to go.
AI Assistant: Have your favorite AI assistant pulled up. (Dom will be using Claude, but feel free to use whichever assistant you prefer!)
🍕 Logistics & Perks
Food & Drink: Pizza and drinks provided!
Parking: Plenty of free spaces available on-site.

AI Agents 101: How to Make ChatGPT Do Actual Work
Most people still use AI like a search box: type one question, get one answer, repeat.
But the next step is AI agents: systems that can take a goal, break it into steps, use tools, remember context, and produce useful work for a human to review.
In this beginner-friendly session, we’ll demystify what AI agents actually are — without hype or jargon. We’ll walk through practical examples of how agents can help with research, planning, writing, coding, operations, and personal productivity.
We’ll cover:
* What makes an AI “agent” instead of just a chatbot
* How agents break tasks into steps
* Where agents are genuinely useful today
* Where they fail, hallucinate, or need human review
* How to design simple AI workflows for your own work
* A live demo of an AI agent-style workflow from start to finish
No coding experience required. This is for anyone who wants to understand where AI tools are going and how to use them more effectively right now.
LOGISTICS AND PARKING:
The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks!
The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
