"DC Kali" is an official training group for FCS Kali. Our curriculum includes knifes, swords, stick-fighting, striking, and grappling; but we place a special emphasis on edged weapons. Please come out and learn some Kali. Our aim is to train hard, learn some sound defense strategies, and make friends along the way. Although FCS Kali is a combat-oriented systems that involves edged weapons, we provide a safe environment for learning w/o sacrificing realism in our training. We teach in small semi-private groups, allowing each individual student to progress as quickly as he or she can absorb the info being taught. Hope to see you all there.

Filipino Combat Systems is an organization dedicated the preservation and promotion of all Filipino Martial Arts. Filipino Combat Systems(FCS) is an organization/system with members from around the world. FCS is based on Tuhon Ray Dionaldo's over 35 years of practicing various FMA (Filipino Martial Arts) styles. He's combine elements of each, into one system that's efficient, fast, concise, and logical. FCS members have extremely diverse backgrounds, and Martial Arts systems. We’ve all come together because of our love of the Filipino Martial Arts, and our unwillingness to become involved in the politics that has so often stifled our growth.

Drop-In Fee: $25/per class (after 1st free Saturday class)

Saturday Dining - Classic Italian at Floriana (Dupont Circle)
**NEW MEMBERS or 1st TIME EVENT GO-ERS**

We are heading to Floriana in Dupont Circle. This is one of DC’s *most consistent Italian restaurants with* a strong reputation for seasonal cooking and house-made pastas.
**FOOD**: Floriana serves Italian cuisine centered on handmade pastas, seasonal ingredients, and balanced sauces. The kitchen emphasizes consistency and clean presentation. Dishes often recommended by diners include cacio e pepe with a sharp cheese and pepper profile, squid ink pasta with seafood for depth and texture, and braised short ribs with rich, slow-cooked flavor. Branzino is frequently highlighted for its light preparation, and risotto dishes rotate with seasonal ingredients. Starters such as burrata, arancini, and calamari are commonly ordered and well received. Desserts like tiramisu and gelato complete the meal.
The cocktail program focuses on classic, balanced drinks with Italian influence, while the wine list leans heavily toward Italian regions with a range of approachable options.
Most members should expect to spend between 45 and 80 dollars for dinner and drinks.

Beyond Cryptography: Geometric Symmetry & Parity Stability
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.

Data & Analytics Wednesday - The Data-Driven Brand
**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.

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.
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
