Data Journalism

Spring is almost here and we're getting ready. The blossoms might be out, the Nats Home Opener is Friday (4/3), and your tech drawer still looks like 2019 😕 Reboot Hour is your monthly Tuesday reset — a casual hangout at Carpool in Ballston where you can play pool, pinball, shuffleboard, or darts, grab a drink, and meet other tech, startup, and climate folks in the DMV. No agenda, no presentations, no speeches. Just a good excuse to get out on a Tuesday and kick off the week before Opening Day. Got old phones, tablets, or laptops collecting dust? Spring cleaning season is the perfect time to bring them in. We professionally wipe all data and get devices to people who actually need them. But bringing a device is totally optional — showing up is the whole point. Think of it as your warmup for the Nats Home Opener. Shake off winter, clear some space, and start the season right. **Details:** Tuesday, March 31st 6:00 – 8:00 PM (drop in anytime) Carpool — 900 N Glebe Rd, Arlington, VA Right off the Ballston Metro **What to bring:** Just yourself. Old devices welcome but not required. A friend, or meet a new one! **What to expect:** Pool, pinball, shuffleboard, darts, drinks, zero pressure — and a baseball game at the end of the week.

**This talk has completely sold out in advance and no door tickets will be available.** [Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“Understanding U.S.-Iran Relations,”** on the origins and future of a longstanding conflict, with Vali Nasr, professor of international affairs and Middle East Studies at the Johns Hopkins University School of Advanced International Studies, co-director of the SAIS Rethinking Iran Initiative, and author of several books on Iran and the Middle East. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-understanding-us-iran](https://events.ticketleap.com/tickets/profsandpints/dc-understanding-us-iran) .] Iran has represented a foreign-policy challenge for the United States for nearly 50 years, with relations between the U.S. and that nation growing more tense and sporadically violent during the first year of President Trump’s second term. Gain an understanding of what has driven the conflict, as well as what the future holds for Iran and its rivalry with the United States, with Professor Vali Nar, a leading expert who has advised senior American policymakers and world leaders on the region and whose many books on it include *Democracy in Iran: History and the Quest for Liberty, Islamic Leviathan: Islam and the Making of State Power*, and the co-authored *How Sanctions Work: Iran and the Impact of Economic Warfare.* He’ll start by taking us back to Iran’s 1979 Islamic revolution, which transformed Iran into a theocracy ruled by ayatollahs who cast the United States as the Great Satan, an enemy to be defeated at all costs. Our nation’s leaders often have blamed religious ideology for Iran’s hostility toward the United States and Iran’s willingness to devote so much energy to confronting a nation halfway around the world. Dr. Nasr will show, however, that such an explanation is inadequate, and he’ll explain how Iran’s anti-Americanism also is rooted in its history, insecurities, anxieties, and ambitions. Professor Nasr will discuss how this anti-Americanism and our desire to contain Iran have shaped U.S.-Iran relations over four decades. You’ll learn how it has led to confrontations in Lebanon and Iraq, as well as to two decades of back and forth over Iran’s nuclear program. It also has skewed Iran’s own domestic policies, deeply impacted the histories of other nations in the region, and brought about war. We’ll consider what more to expect from this rivalry and what Iran’s future holds. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.)

Join us for a cozy, in-person journaling session! Whether you’re new to journaling or a seasoned writer, this meetup is a great opportunity to carve out some intentional time for self-reflection, creativity, and connection with others. Event Outline: • We’ll begin with brief introductions so everyone can get to know each other. • I’ll provide a journaling prompt to help guide your writing. • Afterward, we’ll take about 10 minutes to write quietly. You can use the prompts or go wherever your thoughts take you! • Once we’re finished, we’ll come back together and share (if you feel comfortable). This is a chance to reflect on the process or share insights, but sharing is completely optional. • We'll repeat this process with another prompt or two as time allows. Bring your favorite journal or notebook, and get ready to enjoy some thoughtful, reflective time in a welcoming community. Grab a coffee or tea from the café, settle in, and let’s journal together! Feel free to come as you are—no prior experience necessary. We can’t wait to meet you!

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 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.
