We have taken more than a year off due to the pandemic. Our old favorite cafe in Bethesda is now closed so lets try the Panera Bread down the street on Wisconsin Ave. Please come and join us for some double deck pinochle, assuming (of course) that you have been inoculated for Covid-19 and you are willing to follow the current guidelines of the business on mask wearing. We will start the first game about 6 pm. We play 300 point games so the second game will likely start just after 7 pm, and we will rotate tables if we have more than 4 players. Card players of all level are welcome. We play primarily 4-handed double deck Pinochle but other variants are have been tried on occasion. Games go from 6 pm until Panera closes, which currently is 9 pm. This event is scheduled to repeat every other Wednesday night. Please don't wait until the last minute to RSVP.

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.

Details Location: Crimson Whiskey Bar (Either the downstairs whiskey bar, or main floor bar, TBD) The purpose of Thinkers and Drinkers is to facilitate casual but meaningful and interesting conversations with other people in a face-to-face setting. The topics cover a wide variety of issues and are different for every meeting. While conversations may get heated at times, we ask that all members be respectful of each other and refrain from personal insults. \*\*\* **Contemporary True Crime & Storytelling Most Often Spotlights the Villains:** ***Is there a meaningful difference between understanding a killer and being fascinated by one? Where's the line?*** True crime has always been with us — penny dreadfuls, tabloids, In Cold Blood — but has something shifted in the recent decades. Podcasts like Serial and My Favorite Murder, docuseries like Netflix's Making a Murderer, and entire cable channels dedicated to murder-as-entertainment have turned real suffering into a booming content industry. Is that something to celebrate, scrutinize, or just sit with uncomfortably? Is this part of a larger trend of glorifying the villain? **Some angles worth sitting with:** * The content boom has made this a business — and families are often the last to know. Crime Junkie, Netflix docuseries, Patreon true crime pods — someone is profiting every time a family's worst chapter gets a new season, and several have spoken publicly about learning a docuseries existed the same day the trailer dropped. * The killer gets the marquee, the victim gets a footnote. Dennis Rader (BTK), Ted Bundy, Jeffrey Dahmer, Edmund Kemper — household names, all of them. The people they killed, largely not. * Villains prominent in other entertainment: Sports, movies, videogames etc. * Today's media villains are yesterday's killers. You, Dexter, (some other villain). The world is seen through their eyes and psychology, giving the viewer a sympathetic lense. * Who gets covered is not random. Missing white woman syndrome is documented and measurable; the cases that become cultural touchstones say a lot about whose suffering we've decided is worth dramatizing. * Not every famous case even has a killer to blame. JonBenét Ramsey has been a media fixture for nearly 30 years with no one ever charged — which raises the question of what we're actually chasing when there's no monster to pin it on. **Questions to Consider:** * Does true crime content actually make people safer, or is "awareness" mostly a guilt-free justification for what is really just entertainment? * How many serial killers can you name? Can you name that many victims? * Should producers and platforms be required to involve victims' families — or at minimum, notify them — before releasing content? * Why do you think women make up the majority of true crime consumers, given that women are disproportionately the victims in these stories? * Is the JonBenét phenomenon different in kind — or does an unsolved case just reveal more honestly what's driving the interest all along? * Dahmer merch. Kemper fan accounts. At what point does documenting a killer's story tip into something more troubling? **Major Survey’s include:** **[https://www.edisonresearch.com/the-true-crime-consumer-report-by-edison-research-and-audiochuck/](https://www.edisonresearch.com/the-true-crime-consumer-report-by-edison-research-and-audiochuck/)** **[https://www.pewresearch.org/short-reads/2023/06/20/true-crime-podcasts-are-popular-in-the-us-particularly-among-women-and-those-with-less-formal-education/](https://www.pewresearch.org/short-reads/2023/06/20/true-crime-podcasts-are-popular-in-the-us-particularly-among-women-and-those-with-less-formal-education/)** **[https://www.bw.edu/academics/bios/cv/article-brian-monahan-timeless-kills.pdf](https://www.bw.edu/academics/bios/cv/article-brian-monahan-timeless-kills.pdf)**

Main Library, Meeting Room 2B Join us for a welcoming evening of reflection, gentle music, and meaningful conversation.

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.

**Our April novel is: *The Hong Kong Widow* by Kristen Loesch** **This month’s novel blends gothic atmosphere with historical fiction and chilling horror, set against the haunting backdrop of China. The book is 368 pages in print and 10 hours and 42 minutes on audiobook.** In 1950s Hong Kong, Mei is a young refugee of the Chinese Communist revolution struggling to put her past in Shanghai behind her. When she receives a shocking invitation—to take part in a competition in one of the city's most notorious haunted houses, pitting six spirit mediums against one another in a series of six séances over six nights, until a single winner emerges—she has every reason to refuse. Except that the hostess, a former Shanghainese silent film star, is none other than the wife of the man who once destroyed Mei’s entire life. It is promised the winner will receive a fortune, but there is only one prize Mei wants: revenge. Decades later, the final night of that competition has become an infamous urban legend: The police were called to the scene of a brutal massacre but found no evidence, dismissing it as a collective hallucination. Mei knows what she saw, but now someone else is convinced they know what she did. She must uncover the truth about the last night she ever spent in that house—even if the ghosts of her past are waiting for her there. . . .

**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.
