A beginner-friendly workshop on advanced AI, government policy, and how this new technology is evolving and impacting society. ​​​​**Free and open to the public — no technical background required** ​​​​In previous workshops, we've seen how AI is a transformative technology like no other, for better or for worse. Beyond the technology itself, however, government regulations and societal norms will inform the impact AI has on our world. ​In this workshop, we will explore what policies have been proposed, which have been implemented and why, and what the impact has been so far. How can we use these lessons to maximize the promise and minimize the peril of AI? ​​​​**Over the course of the workshop, we’ll explore:** * ​**Concepts and Goals:** What problems should AI policies be trying to solve? * ​​​​**Different Kinds of AI Policies:** What policies have been proposed so far? What are the pros and cons? * ​​​​**Political Landscape:** How are financial incentives and conflicting ideologies influencing AI policy? * ​​​​**Case Studies:** What can we learn from what's been passed so far? ​​​​**What you’ll get:** * ​​​​A clear, non-technical introduction to core ideas from AI safety, AI governance, and existential risk research. * ​​​​Small-group discussions and thought experiments that connect AI risks to everyday life, institutions, and incentives. * ​​​​A better mental model for evaluating headlines, hype, and claims about AI progress. ​​​​**Format & vibe:** ​​​​This is not a lecture it is an interactive workshop designed to help people think clearly about a topic that is increasingly important and moving very quickly. ​​​​Whether you’re new to AI, casually interested, or deeply unsure what to believe, you’ll leave with a clearer picture of *why* many researchers take AI seriously—and *what’s actually at stake* if we get it wrong.

While the famous cherry blossoms are around the Tidal Basin and Hains Point, the crowds there are truly stunning, it just isn't practical to RIDE there. (Our Tidal Basin cherry blossom rides are ride to the site, park, and walk around). Lucky for us that there are other collections of blossoms around the area. One of the best is up in the Kenwood area of Bethesda. Kenwood hosts around 1200 trees that were planted in the 1930s and 40s. The route is an "out and back" starting from the LBJ Grove / Columbia Island Marina, heading up Mt Vernon trail to Key Bridge, where we cross over and take Capitol Crescent Trail up to Kenwood. We’ll take in the trees, and then reverse route back to the start. **++++++++++++++++++++** **The Meeting Spot:** **++++++++++++++++++++** Columbia Island Marina / LBJ Memorial Grove George Washington Memorial Pkwy, Arlington, VA 22202 [https://goo.gl/maps/8t6o5ZWsQps](https://goo.gl/maps/8t6o5ZWsQps) IMPORTANT: Give yourself ample time to find this location. We are starting from Columbia Island Marina/LBJ Memorial Grove on the river (not Pentagon) side. The location can be difficult to find because it has no exact physical address. USE THE GPS LINKS !! **++++++++++++++++++++** **The Ride after the Ride:** **++++++++++++++++++++** Island Time Bar & Grill at Columbia Island Marina **++++++++++++++++++++** **Ride Level Chart** **++++++++++++++++++++** NoVA CBG tries to accommodate all levels of cyclists by offering different types of rides. We just ask that you come to the ride that suits your current riding ability the best. * Introductory Level : If you haven't ridden a bike in a number of years (or are uncertain of your abilities on a bicycle). * Beginner Level : You can easily ride your bike for 10 miles with some minor hills at a comfortable pace of 10+ to 12+ mph. * Medium Level : You can do 20 miles pretty easily at a moderate pace of 13 to 15+ mph. * Advanced Level : You can do 20++ miles easily at a 15+ pace and / or handle various challenges as rain, night riding, or other odd cycling situations. **++++++++++++++++++++** **The Fine Print:** **++++++++++++++++++++** An RSVP of 'YES' is your digital signature and means you have read and understood MEETUP.com's: * "Terms of Service : Section 6. Release " found at https://www.meetup.com/terms/ * NOVA-CBG's "Assumption of Risk Agreement" found @ https://www.meetup.com/novacbg/pages/1942951/NOVA-CBG_Waiver/ * NoVA CBG's "COVID Policy" found @ http://bit.ly/2021_NoVACBG_COVID19_POLICY Helmets are required to participate in all NOVA-CBG rides. NO exceptions. All riders ride at their own risk and with the understanding that cycling is an inherently dangerous activity. When coming to the meetup you do so voluntarily and are ready and able to participate in the ride as described under the conditions of the day. Be on time for the "pre-ride" preparation. If you do not attend the pre-ride preparation you will not be allowed to participate on the ride. Again, no exceptions.

As always, the goal is fun. Beginners are welcome. We play until 5 or 6. Parking (Free): Plenty of free street parking available on Sunday afternoons near the playing area. Contact Organizer for exact address and other helpful details Metro: Foggy Bottom Metro Station is an 8 minute walk

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.

Expect a fun afternoon of drawing and socializing with like-minded artists! Although each Session is 3 hours, feel free to drop in as your schedule permits. This is a casual gathering, and we know that people might only be able to stay a little while -- drop in, and stay, as long as you are having fun, and as your day allows. **Note: about RSVP's, please respect the RSVP process. If you RSVP YES, you are commited and we are all looking to seeing you. If your plans change however, that's OK, but please be courteous and change your RSVP to NO. We are reaching the headcount limit regularly now and it is rude to take a spot and not relinquish it if your plans change... Respect others; don't be rude. Thank you for your cooperation**. All skill levels are welcome -- this is not a competition. This Group and all its Events are intended to be in equal parts, Drawing/Art AND Socializing. As such, conversation is expected and encouraged. ***However, in all cases, please refrain from discussion of Political topics.*** Our goal is enjoyment, in the form of drawing together while socializing, and political conversation is too polarizing for that to happen. We are looking forward to seeing you there! **Note (in parting): Be aware, and keep in mind that our group, meeting as it does at Starbucks, depends on this business's generosity for the space it allows us. As such, please make a point of purchasing something from the business to express our appreciation as a group using their facility. If you are experiencing hardship and can't afford a modest purchase, get my attention discreetly, and arrangements will be made with no judgment whatsoever. Thank you for your understanding...

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.

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus. Sponsored by [Transform Labs](https://www.transformlabs.com/services)
