[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“The Secrets of Runes,”** on the origins, development, and interpretation of the runic script, with Lilla Kopár, runologist and a professor of medieval literature and culture at Catholic University. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-runes](https://events.ticketleap.com/tickets/profsandpints/dc-runes) .] The fame of runes outshines that of any other ancient script. They can be found not just on Viking Age rune stones, but on Bilbo’s door and as the Bluetooth logo on your cell phone. Runic script is commonly associated with magic, used by modern practitioners of neopaganism, and in recent decades has captured the imagination of filmmakers and video game designers. Yet most of us know little about the historical origins of runes and have no clue how to read or use them. Come to Penn Social to get schooled on runic script with the help of Lilla Kopár, a veteran scholar of runes who has earned a following among Profs and Pints fans by giving fantastic talks on medieval monsters and Norse mythology. As someone who has carried out extensive field research on runes, published several articles on runic objects, and even appeared on the History Channel commenting on runes in America, she’s exceptionally qualified to introduce you to runology and the fascinating things that runes tell us. Dr Kopár will discuss the development of runic script from its humble origins on the borders of the Roman Empire in the first or second century CE, through its popularity in the Viking world, to its use and misuse in modern times. She’ll discuss how runes are a set of related alphabets that underwent changes over time and she’ll describe what inspired changes in this writing system and where and how runes were used in the medieval period. Her richly illustrated talk will highlight some of the most intriguing objects with runic inscriptions, from humble bone fragments to impressive rune stones, and offer insight into the scholarly methods of deciphering and interpreting runic inscriptions. We’ll also look at the function of the runic script from simple practical notes and memorial inscriptions to cipher-runes and magic. The most fun might be the in-class assignment, which will involve reading a few runic inscriptions and writing your name and other words in runes. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.)

Donna's Bar & Grill was a "Brass Band Headquarters" and a fixture in the French Quarter music scene. Hear more about it from Donna herself! We welcome Dr. Donna Poniatowski Sims, who will be discussing her book, *Donna's Bar & Grill New Orleans.* The book contains first person narratives that bring stories of the “Brass Band Headquarters” to life through the sharing of memories and memorabilia. Extensive photographs and taped interviews of the musicians and patrons of the iconic French Quarter music venue are the foundation of the author’s articulation of the club’s influence on the evolution and promotion of brass bands and Mardi Gras Indians into New Orleans club venues in the 1990s and early 21st century. At the time of this writing, many have achieved fame and recognition on the national and international stage as well. Also included is the history of the many New Orleans artists whose musical careers began in a brass band and morphed into straight-ahead jazz (bebop) and/or classical or other genres such as Zydeco and Blues/Rhythm and Blues. This book, a personal form of documentation about a real place and its events, contributes a memorable perspective to the cultural history of the remarkably unique New Orleans style of music which has influenced other musicians and composers around the world. Dr. Donna Poniatowski Sims, educator (K-12 and university level), and her husband, Chef Charlie Sims, were restaurateurs and owners of the music club, Donna’s Bar and Grill (which was noted for playing brass bands), and located at 800 N. Rampart for almost 18 years (1993-2010). Donna already knew many of the jazz musicians from her previous restaurant/music club, Janek’s, at 711 Bourbon which she co-owned from 1976-1980 with her first husband, John Poniatowski (deceased-1991). Donna has also been published as a photographer and has written numerous curricula for educational purposes. Charlie was the chef for Donna’s Bar and Grill and Head Chef for Amtrak’s “City of New Orleans.” [Registration ](https://www.eventbrite.com/e/prjc-jazz-talk-donnas-bar-grill-new-orleans-wdr-donna-poniatowsk-sims-tickets-1975364916641?aff=ebdsoporgprofile)required by 5:00 p.m. Eastern time the day of the presentation to receive the Zoom link.

**AI-Supported Creative Exploration** *For Unassuming Intuitives & Practicing Creatives* (Please note that this event has not been organized or endorsed by The Writer's Center.) This meetup is part of AI as Creative Partner — A Practice Group, a set of open, non-sequential creative labs you can join at any point. We use AI as a thinking partner—not to replace your ideas, but to help surface and shape them without overthinking or pressure. You bring fragments—ideas, impulses, unfinished concepts. With AI as a supportive collaborator, we explore how those fragments can become clearer, more coherent, and ready to share if and when you want to. No technical background is required. If you can talk or type, that's enough to work with AI here. This session is intentionally low-commitment and flexible: * Arrive late or leave early * Work quietly or observe * Ask questions, or simply watch the process unfold There's no presentation and no expectation to finish anything. Showing up as you are is enough. **CREATIVE WORK, GENTLY - AN OPEN PRACTICE NIGHT** This is not a workshop or a class. It's a calm room where people show up to work creatively—without urgency, performance, or pressure—using AI as a thinking partner. Come for 20 minutes or stay the whole time. Work quietly, observe, or ask questions. This space adapts to how you arrive. **HOW TO FIND US** Look for the room with the door open on the lower level. Look for the guy with the screen projector and ambient light and sound. Feel free to just walk in and settle. **(*This is an independent meetup using rental space at The Writer's Center. The Writer's Center has not organized or endorsed this event.*)**

Learn to manage stress and achieve self-growth through simple relaxation and Meditation. Heartfulness Meditation is a simple, modern, methodical approach to meditation. Rather than homing in on your breath or repeating a mantra, you simply focus inward, on your heart, to cultivate inner strength and serenity. Heartfulness meditation is gaining traction in recent years. It focuses on the heart, allowing individuals to connect with themselves on a deeper level, and ultimately achieve peace, relaxation, and clarity. It is a practice that encourages patience, self-compassion, and acceptance, helping cultivate a deeper appreciation for the present moment. This practice is offered with love and at no cost

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.

**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.

**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.

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.
