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.

**Join us in Falls Church for conversations that go beyond small talk.** Higher Grounds – Falls Church is where this growing network of gatherings began: a space for thoughtful, authentic dialogue about what matters most. Whether we’re exploring the nature of happiness, the challenges and possibilities of midlife, spirituality, culture, capitalism, parenting, or the role of art and travel in a meaningful life, every conversation is shaped by the people in the room. There’s no set leader or rigid agenda—just a shared commitment to listen as much as we speak. We start with brief introductions focused on what makes you *you* (not your LinkedIn bio), then dive straight into whatever is on people’s minds. The direction of each meetup emerges organically, making every event unique. MANDATORY: PLEASE REVIEW OUR COMMUNITY GUIDELINES IN THE GROUP DESCRIPTION. Everyone is expected to engage in respectful conversations and listen deeply as well as share. We have a zero tolerance policy of sexual harassment and hate speech. Come ready to share, reflect, and connect with others in Falls Church who are also seeking deeper conversations. **Suggested Questions: Life Stages & Transitions** 1. What did you think you'd have figured out by now that you're still completely winging? 2. When did you realize your parents' advice was for a world that no longer exists? 3. What are you finally old enough to stop pretending to care about? **Suggested Questions: Identity After the Roles** 1. Who are you when nobody needs anything from you? 2. What dream keeps resurfacing even though the "practical" time has passed? 3. How do you handle having the freedom you always said you wanted? **Suggested Questions: AI & Being Human** 1. What human experiences will AI never truly understand? 2. If machines handled all your have-to's, what would you actually do? 3. What becomes more precious as everything becomes automated? **Suggested Questions: Belief & Meaning** 1. What certainties have you given up, and what rushed in to fill that space? 2. How has knowing someone who died changed how you live? 3. What do you believe now that would shock your younger self? **Suggested Questions: The Modern Psyche** 1. What anxiety do you carry that previous generations didn't have? 2. Which of your survival strategies are you ready to retire? 3. What uncomfortable truth about happiness did it take you years to accept? **Suggested Questions: Work & Purpose** 1. When did you stop believing that your job would complete you? 2. What would you do for work if money and status weren't factors? 3. How has your definition of "making it" changed over the years? **Suggested Questions: Relationships & Connection** 1. What relationship dynamic do you keep recreating, and why? 2. When did you realize your parents were just people trying their best? 3. What kind of loneliness doesn't go away even when you're with others? **Suggested Questions: Time & Mortality** 1. What are you running out of time to say or do? 2. How differently do you spend your time knowing it's finite? 3. What will you regret not trying, even if you fail? **Suggested Questions: Society & Culture** 1. What social convention do you follow even though it makes no sense? 2. Which generation do you understand least, and what might you be missing? 3. What aspect of how we live now will seem insane in 20 years? **Suggested Questions: Personal Philosophy** 1. What rule for life did you create after learning something the hard way? 2.

Let's visit my favorite Balkan/German restaurant in Old T. In my humble opinion, they have the best schnitzel in this area! They may have a special Easter menu. If there's interest, we could go to a movie afterwards. [MENU | old-house-cosmo](https://www.oldhousecosmopolitan.com/menu-2)

**Real connection with fellow Catholics who are eager to grow in Faith and friendship!** This 3 year--- 45min deep dive into the Catholic faith is a great way to spend your Sunday rest day. When you are ready to dig deeper and live the faith more fully this is an optimal opportunity. Talk yourself into this! You may start whenever and can come as often or as little as you desire. Coffee is served w/ small donation. It is taught by the priest and/or OCIA director at St Louis Parish who are ALL fabulous- faithful educators filled with theologically inspired knowledge. You can ask questions at the end, which I love. It is just a wonderful experience to grow. Afterwards if you wish, you can also find your way over to the Little Way Cafe Coffee shop across the parking lot to stay for more community time or read some of the excellent books that line the shelves throughout. If you are new to the community of Alexandria and want to meet like minded folks or a veteran of it, this is a special and unique opportunity and did I mention it is free? :) Hard to believe! Please join me every Sunday at 945 am.

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.
