**Location**: Tysons-Pimmit Regional Library (Virginia) Conference Room A game development **Working Session** involves 3 key parts: 1. Tell people what you're going to do 2. Actually do stuff 3. Show people what you did That's what we'll be doing for this meeting. We'll briefly tell each other what we're going to do, then work on our projects, then at around 5:30 wrap up to show each other what we did and chat for a bit. You don't have to stay the whole time, so feel free to drop in and out as you have time. All game development skill levels welcome. Whether you're bringing a game you're trying to ship in a month, or you're just planning on following some tutorials or trying out a new tool to improve your skills, use this time to make progress. Working sessions also train you to think about the scope of your work: pick a chunk of work that you can complete in the time that we have. That way you can end the working session with a feeling of accomplishment! **What to bring**: Laptop, Charger, maybe a power strip if you have one handy, any other game development tools you need. Try to download any software you need before the working session. There is Wifi at this location, but it may be slow if you have to download any large files.

We’re still working to get more people into these Meetups, but our goal is to give PlayYourCourt members a few social tennis outings each week in addition to your practice sessions and Challenge League matches. These Meetups are co-ed, super laid back, and all skill levels are welcome. Post your skill level and a suggested court in the comments section so we can round up as many players as we can for some tennis fun! Also, if you’re looking to meet new practice partners or play some matches and you aren’t already in the PlayYourCourt Community, you can go here to see what we’re all about and sign up: https://www.playyourcourt.com/tennis-community/washington-dc/meetup/ If you love tennis, we’d love to have you! Be sure and watch the quick video that explains how everything works. Happy hitting! - Scott

Let's get together to play some competitive coed doubles volleyball. **COST**: FREE **Court Type**: Outdoor grass **Minimum Skill Requirements**: Solid BB (click [here](https://docs.google.com/document/d/1PojSi4qdlRsv1msCHhvpQ43iDc4FfzQwpWCc3kafVMY/mobilebasic) for details) Attention: 1. This event is **not always on a first come, first served basis**. [Good doubles partner](https://docs.google.com/document/d/14weEw-P52XKx0P8K2l-ZOFtYU61wmfdkSkopbG5avro/) and those who can bring a net and ball, may get priority over others on the waitlist. 2. Since skill levels are **self-reported**, some attendees may not meet the expected level in reality, so we encourage you to choose a partner you can enjoy the game with, and since this is a **competitive** event, it is okay if you make a strong team and win all the games. 3. Each person must help set up and take down one net, leaving some nets unset for latecomers. **Smiley Social documents:** 1.

Title: Beyond Cryptography: Geometric Symmetry & Parity Stability Summary: Decoding Chaos: Using Quantum-Inspired Symmetry Metrics to Detect Stealth Attacks in High-Stakes Infrastructure. Agenda: Why symmetry matters after the proof is done. Symmetry as an Invariant Symmetry as a Security Primitive Trust as a Continuous Function Live Thought Experiment Engineering, Implications & Open Questions Move away from traditional bit-matching and discuss "Symmetry Drift." Explain how system states can be modeled as high-dimensional manifolds where an attack represents a geometric deformation.T(t)=f(symmetry stability,parity consistency,temporal coherence) Speaker: Vijay Krishna Vijay is a security engineer focused on runtime observability and symmetry drift in cryptographic systems. He is the founder of Vyapti Resonance and the creator of the Quantum Security Probe (QSP), a telemetry-driven integrity monitoring framework for post-quantum infrastructures. His work bridges theory, engineering, and long-lived system behavior, emphasizing measurable trust over binary verification. Vijay has 9 accredited licenses in Quantum Computing. Career Snapshot: Microsoft → DuPont → Rockefeller Capital Management → Morgan Stanley → New York Life → Founder, Vyapti Resonance Across this trajectory, Vijay has operated at the core infrastructure layer of organizations—cloud platforms, identity systems, distributed compute, reliability engineering, and governance frameworks. His work has consistently involved systems that cannot fail, particularly in regulated financial and insurance environments. This enterprise grounding strongly informs his academic and research outlook: quantum and AI systems must be operable, governable, auditable, and teachable, not merely theoretically elegant.

We play a variety of games with a focus on high interaction Euros. Events will start with quick games while people arrive and eat lunch. We will start longer games between 1:30pm and 2pm. While the official end time is 5pm, people are welcome to continue playing games afterwards. Western Market closes at 7pm on Sundays. This page has more examples of high interaction Euros: [Old-school German-style Games](https://boardgamegeek.com/guild/view/3948).

A beginner-friendly workshop on advanced AI, government policy, and how this new technology is evolving and impacting society. ​​​​**Free and open to the public — no technical background required** ​​​​In previous workshops, we've seen how AI is a transformative technology like no other, for better or for worse. Beyond the technology itself, however, government regulations and societal norms will inform the impact AI has on our world. ​In this workshop, we will explore what policies have been proposed, which have been implemented and why, and what the impact has been so far. How can we use these lessons to maximize the promise and minimize the peril of AI? ​​​​**Over the course of the workshop, we’ll explore:** * ​**Concepts and Goals:** What problems should AI policies be trying to solve? * ​​​​**Different Kinds of AI Policies:** What policies have been proposed so far? What are the pros and cons? * ​​​​**Political Landscape:** How are financial incentives and conflicting ideologies influencing AI policy? * ​​​​**Case Studies:** What can we learn from what's been passed so far? ​​​​**What you’ll get:** * ​​​​A clear, non-technical introduction to core ideas from AI safety, AI governance, and existential risk research. * ​​​​Small-group discussions and thought experiments that connect AI risks to everyday life, institutions, and incentives. * ​​​​A better mental model for evaluating headlines, hype, and claims about AI progress. ​​​​**Format & vibe:** ​​​​This is not a lecture it is an interactive workshop designed to help people think clearly about a topic that is increasingly important and moving very quickly. ​​​​Whether you’re new to AI, casually interested, or deeply unsure what to believe, you’ll leave with a clearer picture of *why* many researchers take AI seriously—and *what’s actually at stake* if we get it wrong.

Join us for a meetup lunch! Meet new people and make new friends. This will be a small size group for lunch. Members only please I Will have a reservation. Easy free parking! See you there!

We meet to learn and practice American Sign Language and to grow our familiarity with Deaf culture.

As we learn, we hope to connect more with the Deaf community in Central Ohio. Join us as you're able! Come regularly or just once - whatever you're looking for! Each meetup will explore different topics related to ASL/Deaf culture, and will feature time to practice conversation with one another. Just bring yourself and a willingness to learn!

Pay attention! We’re delaying a week for those of you who may be on Spring break and/or celebrating the holiday. Ok, no pancakes, but waffles-a-plenty. Join the local UX and Digital Design community for a casual monthly breakfast. Look for us upstairs!

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus. Sponsored by [Transform Labs](https://www.transformlabs.com/services)

**The Data-Driven Brand: Using Analytics to Shape Perception** Can you use analytics to improve tacos? This being CBUSDAW, we think the answer is probably “yes”, but we’re not sure how to implement or test this theory. For our April meetup we’ve got Sara Kear, CMO of Condado Tacos, to investigate this delicious question. Sara will explore how she blends quantitative data and qualitative customer feedback to shape brand positioning and drive business decisions. We all know that marketing and analytics go way beyond attribution. Sara will show how Condado uses customer insights to inform product and pricing strategy. She’ll also highlight how Condado leverages customer feedback at scale to influence operational priorities, positioning marketing as the voice of the customer across the organization. In the last 12 years Condado has gone from one location in Columbus to 52 locations across 10 states, so we’re guessing there’s more to that growth than really good guac (though the guac probably helps). Ultimately, this talk focuses on the intersection of art and science—using data to inform creativity and build a brand that resonates with customers in a measurable way. **About Our Speaker** Sara Kear is Chief Marketing Officer at Condado Tacos, where she oversees brand, restaurant design, menu and pricing strategy, off-premise including catering, and customer data strategy. Since joining in 2021, she has helped grow the brand from 19 to 52 locations while building a data-driven marketing organization focused on loyalty and customer insights. Condado has since been named to the Inc. 5000, recognized as Breakout Retailer by Chain Store Age, and consistently ranked among FastCasual’s Top 100 Movers & Shakers.
