**\* This is an in-person event** Most people only experience finished products. Very few get the opportunity to work on something before it's finished when it can still be shaped. This is one of those opportunities. Karen Hold, Director of DT:DC, is currently developing a new innovation skills workbook with Jeanne Liedtka, based on over a decade of teaching and working with leaders across organizations, universities, and the DT:DC community. Her work focuses on the five statistically validated skills that help people develop as innovation leaders. This workbook builds on her work in design thinking and innovation education, including programs at the University of Virginia Darden School of Business, École des Ponts Business School (Paris and Casablanca), and Boston College. For this session, Karen will share a draft chapter of her new workbook for live testing. This is not a polished workshop. It's a working lab. You won't just participate. You will help shape the material itself. What We’ll Be Testing: * Whether the exercises actually help people think differently * Where the material is clear and where it breaks * What feels useful vs. what needs to be reworked This is the kind of work that typically happens behind closed doors. **What You'll Do** Working in small groups, you will: * Work through exercises from a draft chapter of the workbook * Apply them to real situations and ideas * Share feedback on what is clear, confusing, or missing * Help identify how the material can be improved You’ll get: * Early access to work that is still being developed * A chance to influence how this material evolves * Practical tools you can immediately apply * A behind-the-scenes look at how skill-building experiences are designed This is a rare opportunity to be part of the process, not just the outcome. Join us if you want to be part of something early, unfinished and actively evolving. No prior experience is required. **About Karen Hold** Karen Hold is the founder of Experience Labs and Director of DT:DC, one of the world's largest innovation communities connecting founders, designers, policymakers, and changemakers. Her work sits at the intersection of teaching and real-world application. She works with Fortune 500 corporations, federal government agencies and non-profit organizations, helping teams strengthen how they think, make decisions, and move ideas forward. She teaches in graduate and executive education programs, including at the University of Virginia Darden School of Business, École des Ponts Business School (Paris and Casablanca), and Boston College. Karen is a co-author of *Experiencing Design – The Innovator’s Journey*, and her work focuses on developing the skills that enable individuals and organizations to navigate complexity and create meaningful change.

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)**

**THE POWER OF THE SUBCONSCIOUS OVER YOU** You are welcome to arrive 15 minutes early for refreshments! At the lecture "The Power of the Subconscious", the speaker will clearly and understandably explain topics such as: * What is the exact definition of the Subconscious Mind? * How does it inflict unwanted feelings and anxiety in you? * What determines how much pressure it exerts on a person? * What exactly is the goal of the subconscious? This is not just a lecture where you sit quietly and listen. It's interactive and LIVE, so you can ask questions at any time. And the most important topic: **HOW DO YOU TAKE CONTROL OF YOUR SUBCOUNSCIOUS!** This group is sponsored by the Dianetics Life Improvement Center.

**The rules are simple:** Take photographs **Each and Every Day** and post your best **ONE** (1) shot of the day - **EACH DAY** for **April**. If you happen to miss a day or two (life happens), it is **OK** to catch up and upload the photos for the days missed or just skip those days. **Please don't post over 2 to 3 at a time**. This is part of the learning process. **DO NOT POST TO THE ALBUM *UNTIL* AFTER 04/01/2026**. Please use a browser like Chrome and the Meetup.com website to post the images, as **the Meetup app does not handle albums very well**. Towards the top-left of the page is a link to **Add Photos** for uploading your photo to the album. **CONFIRM** **that your photo was Added to the correct Album.** Remember to post your **best photo (JUST ONE)** you took every day on that day! **DO NOT POST PHOTOS FROM ANY OTHER TIME!** If you have time to post an older image, you can take a new image and post it. Be creative. Please **add a caption** to know how far you are in the process. After you upload the image you took that day, find your photo at the end of the album, and edit the caption to state the day and total of days in the month like this:**?/30**. You can add the title of the image if you wish. A good title can make a photo! So, your photo for the **April 1st** caption would be "**1/30: My great photo!**" \*\* Adding a caption helps you keep track of where you are in the month. It does help. The purpose is to have fun and get in the habit of shooting every day. Learn to use your camera. Read your manual and test out a new feature you have never used before. Sometimes picking a theme/project can help focus (pun intended), like flowers, your pet(s), a lens you haven't used in a while, or whatever your passion is. Or try something new... The **end date is 04/30/2026**. Meetup.com does not allow events to be longer than 2 weeks. Other images that were not taken by you will be removed. Please keep the images family-friendly. You need to be a member of the Virginia Beltway Photography Group. I look forward to seeing how far people go and grow as better photographers!

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.

**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.
