Everyone’s prompting. Few people are judging. This talk shows how a playwright uses multiple LLMs and vibe coding to build a custom evaluation loop: a digital dramaturg that checks scenes against an outline like a living spec. If you design, build, or eval AI systems, you’ll leave with a new mental model for using LLMs as QA, not just content engines. **Featured speaker:** * [Soo-Jin Lee](https://www.linkedin.com/in/soo-jinlee/)\, Gen AI Conversation Designer \| Prompt Engineer \| LLM\, NLU\, NLP \| Human in the Loop \| Former Teacher \| Playwright **Location:** AWS Skills Center, 1550-G Crystal Dr, Arlington, VA 22202 **Drinks and Networking After:** --> Alamo Drafthouse, 1660 Crystal Dr, Arlington, VA 22202 (2nd Floor) **Description:** Join us at AI Innovators Network for our upcoming meetup in the Mosaic, which is dedicated to exploring the latest trends in Artificial Intelligence.

**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: **“The Love Lecture,”** a contemplation of matters of the heart, with Laura Papish, associate professor of philosophy at George Washington University and teacher of a seminar on the philosophy of love, sex, and friendship. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://www.ticketleap.events/tickets/profsandpints/hill-center-love-lecture](https://www.ticketleap.events/tickets/profsandpints/hill-center-love-lecture) .] Who wrote the book of love? Why does love have to be so sad? Is it a thin line between love and hate? On a more serious note, how does our society's understanding of love and romantic love shape our experience of it? Why do we think of love as mysterious and irrational? Do those we love need to be lovable? Is love necessarily a morally good thing, or can it actually make it harder for us to be good? Show your love for learning by hearing such questions tackled by Laura Papish, who has built a considerable following among Washington D.C. fans of Profs and Pints with her annual talks exploring the intersection of the brain, the soul, and the heart. Hilariously accompanied by her husband, Chris (on guitar), she’ll offer up a delicious assortment of thoughts about the upcoming Valentine’s Day holiday—some dark, some sweet, and some giving you plenty to chew on. Dr. Papish will start by examining how ancient Greeks thought about erotic love and move on from there, looking at how love is envisioned in modern thinkers, classic novels, recent films, and pop culture. She’ll also discuss the origins of the idea that people have a “soul mate” and how some thinkers have tried to criticize or transform the very concept of love. Together, we'll explore different possibilities for love and those mysteries about it that have left more than a few of us feeling befuddled. Feel free to show up if you are lovelorn, love-stricken, or just love to hear a fascinating discussion. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.)

Join us to enjoy an exclusive 5-course tasting menu ($100/pp) at Chef Edward Lee's groundbreaking restaurant - **Shia** \- in the Union Market District\! Note from SHIA: Due to our committment to sustainability and preventing food waste, we prepare specific ingredients for each guest daily. A charge of $85 per guest will be applied to any cancellations within 48 hours of the booking. $85 Event Registration fee will be applied to each guests's bill. Event registration fee is only refundable if the seat is filled by another guest prior to the dinner. Thank you for your understanding. \*\*Note from Shia re:Dietary Restrictions:\*\* Due to the inclusion of ingredients integral to Korean culture and cuisine, we ***cannot*** accommodate the following dietary restrictions: celiac, soy, legume, nightshade vegetable, or allium. We ***can*** accommodate vegan, vegetarian, pescatarian, seafood allergies, shellfish allergies, and nut allergies. The adjusted dishes our chefs have created for these dietary restrictions will be vegetarian, as we do not have the ability to substitute proteins. Individuals with aversions to seafood may not fully enjoy the experience, as a large portion of our menu is seafood-based at this time. Please note that our kitchen operates on a minimal-waste, sustainability-driven model. This means we do not stock additional ingredients for last-minute changes. If we receive notice less than 48 hours before your reservation, we may need to omit elements of dishes rather than substitute additional ingredients. Please let us know right away so we can prepare with care. **The Washington Post** (Sietsema) Over my decades-long watch, few restaurant genres have witnessed more changes in and around Washington than Korean. Back in 2000, the majority of sources were in the Virginia suburbs, where the menus mostly revolved around tried-and-true mandu, bulgogi, seafood pancakes and barbecue. Before the rise of social media, restaurants that specialized in certain dishes **—** say, Tosokjip in Annandale, known for its grilled fish and stews **—** existed under the radar, supported primarily by the Korean community, recalls restaurateur Danny Lee, one of the agents for change on the D.C. scene. Over the years, practitioners started cooking outside the lines and experimenting with fusion. The arrival of Lee’s Chiko and Anju in the District saw chefs feeding us Korean fused with Chinese American ideas and serving upscale homestyle cooking. Service (and alcohol beyond beer and soju) became a priority at restaurants including Ingle Korean Steakhouse in Vienna, and Korean chefs, following the lead of the trailblazing Atomix in New York, hopped on the fine-dining bandwagon with tasting menus. I miss the short-lived Incheon in Annandale but welcome the youthful Onggi in Dupont Circle. Since November, chef and cookbook author Edward Lee is pushing the envelope even more, with a gem called Shia — “seed” in Korean — tucked in the Union Market District. It’s a slip of a place with a dozen seats in the front bar and nearly double that number in a narrow dining room behind a slatted maple door. What distinguishes Shia from the pack is that it’s part of the chef’s nonprofit, the LEE Initiative, originally introduced as a mentoring program. Further, Shia is experimenting with all manner of limited-waste and sustainable practices, which is why some drinks arrive sans garnishes, and there’s no gas and zero plastic. After the kitchen turns them into pulp, used cocktail napkins and printer tickets enjoy afterlives as postcards and coasters. No one preaches here, by the way; they just quietly set good examples. Lee wants his clientele to experience Shia as a restaurant vs. a lecture hall. “This is how we say hello,” says a server as he places a little cup in front of us, trailed by a snack: a hot oyster and scallop bundled in jin, or seaweed. The dish, which you eat with your hands, marries hot seafood, cool Asian pear and spicy ssamjang, an exquisite bite that’s gone as fast as you can read this sentence. The contents of the cup, a tea made with soju and dried omija berries, are refreshingly sweet-tart. Guests seated at the bar are offered a five-course menu; those seated in the dining room, host to the open kitchen, receive seven courses. Shia remains enough of a tough reservation that I’ve been able to secure a seat only in the lounge, a serene space with gold lights, a concave ceiling and wallpaper that depicts clouds mingling with mountains. Scrolls of amberjack arranged on thin red rings of fermented fish paste and lemon juice are topped with little balls of foam that taste like kimchi “air.” (The finishing touch demonstrates Shia’s no-waste goal; the cloud is excess liquid from making kimchi, passed through an aerator.) The lovely fish dish is a spin on the refreshing Korean summer dish mul hwe, to which a delicate, fresh-tasting green chip is added. (The fillip turns out to be hand-harvested gamtae, the rarest of seaweeds in Korea.) We miss the small plate when it’s gone, but only until the pork belly replaces it. Finger lengths of the braised meat share a canvas with abalone and clams scattered on a soothing porridge of barley, buckwheat, millet and three kinds of rice infused with dashi. “Try to get a bite in each bite,” a server coaches my party. Rising from the center is a little tower of fierce white kimchi, which the server says to save for last, “but you do you.” Some nights look like an evening out in Seoul. My visits found different generations of Koreans sharing Lee’s handiwork, a reality the chef addresses with menus printed in Korean as well as English. The owner sees adventure-seeking younger Koreans come in to check the place out, then return with their parents to share the novelty. The Korean menu is meant to make older customers “feel at home.” Surely the saengseon contributes to the sentiment. A square of seared braised sea bass — line-caught, of course — lounges in a liquid salad of crisp greens and broth and practically demands my return engagement. The intoxicating flavor of the soup springs from what Max Chuvalas, who shares the executive-chef title with Chaelin Lee, calls a “fish tea,” an elixir coaxed from fish scraps and white kimchi juice. I also admire the duck, glazed with Korean mustard and presented so the sliced meat alternates with same-sized pieces of gently crisp mountain yam. The accompanying steamed rice, offered in a raised wooden bowl and bulked up with ginkgo nuts, aster, shepherd’s weed and thistle, nearly steals the show. The greens are another salute to sustainability: “Where Americans might see weeds, Koreans see edible flora,” says Chuvalas, who comes to Shia from Dirty Habit but has worked in fine-dining restaurants before. Those who opt for five courses choose between the fish and the duck. The seven-course plan includes both indulgences. My strategy at the bar with a companion has been to order one of each and share tastes. When I first started as The Washington Post’s critic, Asian desserts were mostly predictable. Green tea ice cream was almost always involved. Shia demonstrates how far the scene has come, with endings including bruleed bananas staged with banana chips, same-flavored ice cream and soy chocolate sauce, a fruit salad that changes with the season but always looks like a brilliant orchard, and a honey tuile hovering over apricot foam. The longer script in the dining room embraces extra sweets — caramels and what tastes like a pecan pie from Korea (pine nuts and dates are involved) — revealed in a handsome mirrored box. In recent years, chefs of all stripes have gotten better about offering tasting menu portions that are neither too tiny nor too filling. No one feels compelled to go to the Golden Arches after a meal at Shia, nor will they feel the need to let out their belt. “I’m 53,” says Lee. “As I get older, I don’t have the patience for 20 courses and three hours” of sitting and eating. The chef feels that seven courses, the max here, honors “efficiency and variety.” Hear! Hear! And go! Go! Looking forward to sharing this experience with you! ***Menus change seasonally***.

Hello Social Sips and Bits Family, Join us for a fun evening of drinks and bites at The Yard House! It's the perfect chance to connect with friends, both old and new, in a relaxed setting. Bring a friend and please RSVP so we can save a spot for you. We can't wait to see you there!

***In Person Location:*** Rockville Library, second floor meeting room (Collaboration Room 3). We are experimenting with a new virtual join link - [https://meet.jit.si/mocomakers](https://meet.jit.si/mocomakers) If you can make it in person, that's always recommended! Let's resume repeated full end-to-end testing cycles and continue to iterate our design and resolution. Our community is building (and documenting for other teams) how to build a scanning tunneling microscope using a mix of common and 3D printed parts. This will allow us to scan and visualize a single atom - an ambitious we are doing over the course of a few months. The MoCo Makers community is one of the most innovative and competent groups in Maryland, and we've done everything from [publishing cancer research](https://pubmed.ncbi.nlm.nih.gov/38136356/), to [launching products](https://www.kickstarter.com/projects/gotim/cozy-curvy-multi-contour-pillow), [winning grants](https://covidinfocommons.datascience.columbia.edu/awards/2014255), and inspiring thousands. Now our biggest challenge yet has appeared. We are building a Scanning Tunneling Microscope, that will allow us to scan and visualize single atoms. Does it sound hard? Perhaps.. However! I have every confidence that we are now operating at a level were we can take on this mean, cross-functional project. We continue to build on our past successes, and a key technology we previously applied was increasing the signal of small voltages using OpAmps - which we did during our custom pH Probe project - [https://www.mocomakers.com/ph-probe/](https://www.mocomakers.com/ph-probe/) \- That technology is exactly what we need to get this machine working\, and at a high precision\! To get a better idea of what we are doing, see our reference project here: [https://www.youtube.com/watch?v=7N3OqTEq08g](https://www.youtube.com/watch?v=7N3OqTEq08g) All starting CAD, code, and reference files should exist. However, let's be the first Maker community to document the build process and share it with learners around the world. We have a bit over $2,000 in materials costs, so if you want to sponsor this project, and get banners at events with 20K attendees, and access to our email broadcast of 30K members, please contact matt@mocomakers.com We are also open to university, lab, or community partnerships so feel to reach out if you want to be part of this project. Together, we can do incredible things. ***In Person Location:*** Rockville Library, second floor meeting room (Meeting Room 3). To Join Virtually: https://meet.jit.si/mocomakers

Title: Biology-Inspired Neural Networks with Multi-Directional Propagation of Values and Distributions Date: Feb 8 2026 10:00 am - Noon EST Summary: While biological axons can propagate in both directions, current ANNs are focused on unidirectional propagation. Also usually they only propagate values, while uncertainty is shown also crucial for making decisions of biological organisms - suggesting to propagate also variance, probability distributions. I will talk about novel KAN-like approach to ANNs repairing these lack by using neurons containing inexpensive local joint distribution model as polynomial, allowing to freely change propagation direction by just switching indexes, also propagate entire probability distributions represented by vectors of moments. Beside backpropagation, it also allows many additional training approaches, like direct estimation, tensor decomposition, and through information bottleneck. Speaker: Dr Jarek Duda is an assistant professor at Jagiellonian University. He holds degrees in computer science (PhD), mathematics (MSc) and physics (PhD). He is mainly focused on physics foundations, information theory, statistical analysis, and is known for introduction of asymmetric numeral systems. Moderators: Dr. Pawel Gora, CEO of Quantum AI Foundation and Dr. Sebastian Zajac , member of QPoland Zoom registration form will be provided no later than 1 hour prior to the event's start time.

Date : Feb 7 2026 13:00 - 15:00 EST Title: Symmetry, Topology, and Magnetoelectric Multiferroicity — Ferroelectric 'Tweezers' for Quantum Magnetism in Hexagonal Ferrites Abstract: The scalability of future quantum and spintronic hardware is currently facing a "physical wall": the challenges of excessive heat dissipation and environmental magnetic noise. To overcome these barriers, materials where magnetism can be controlled with high precision and minimal energy will be highly desirable. Magnetoelectric multiferroic hexagonal rare-earth ferrites (h-RFeO3, R: rare earth) have emerged as an important platform for this mission, offering a unique "playground" where symmetry and topology dictate functionality. In this talk, I will provide a comprehensive overview of research progress on these materials over the last decade. We will explore how a specific structural transition—trimerization—breaks symmetry to create a robust state known as improper ferroelectricity as well as weak ferromagnetism. The coupling between the ferroelectric and magnetic orders leads to a "ferroelectric tweezer" effect, where the material's ferroelectric domain spatially anchors and manipulates magnetic domains. Furthermore, we will address the "readout challenge": how to detect the diminutive magnetic moments inherent in these systems. I will show how the non-coplanar spin topology acts as a signal amplifier, enabling high-fidelity readout of magnetic states through spin-transport. By understanding the "solid science" of these complex oxides, we can define the roadmap for a new generation of stable, low-power topological electronics. Biography: Xiaoshan Xu is Susan J.

NFT's are here to stay folks! This is a group for like minded people interested in understanding, leveraging, using, creating for, profiting from, trading too i suppose, NFT's.. everything around them, complexity, fear and exploits, best practices and more. **PLUS** This group will talk AI ART tools, techniques, artists, video, audio, prototypes and more in the AI assisted production space- ART specifically, but we can get into any aspect of some of the cooler things happening in AI in general.

**People Analytics 101: Making Sense of Compensation Data** Compensation data is one of the most widely used and widely misunderstood forms of people analytics. The session will cover where compensation data comes from, including market pricing data, internal payroll data, and benchmarking sources, and how companies think about structuring and analyzing that information. We will explore how compensation data is leveraged to set salary ranges, manage internal equity, support hiring and retention, and align pay with business strategy. A portion of the session will address common data challenges and limitations, such as market noise, inconsistent job matching, and incomplete datasets, while keeping the primary focus on practical use rather than technical depth. The session will also look ahead at where the space is going, including the growing impact of pay transparency laws, expanding pay equity requirements, and emerging regulations in the US and Europe that require organizations to report on gender and pay gaps. The goal is to give attendees a clear mental model for how compensation analytics works today and why getting it right is becoming increasingly critical. (note: we are back at Rev1 this month!) **About Our Speaker** [Alex Moore](https://www.linkedin.com/in/alexscottmoore/) is the founder of [Moore Cooperative](https://moorecooperative.com/), where he advises organizations on compensation strategy, pay equity, and people analytics.

OWASP is ending use of Meetup, so I built an eventbrite for the event. https://www.eventbrite.com/e/ai-development-risk-case-studies-and-how-agentic-ai-is-the-future-of-appsec-tickets-1981450622150?aff=oddtdtcreator AI is transforming how software is designed, developed, and deployed, dramatically accelerating velocity while introducing new categories of risk. As organizations adopt AI-assisted coding, autonomous agents, and increasingly complex model interactions, traditional application security approaches struggle to keep pace. This talk examines emerging AI-driven risks through real case studies from the field, highlighting issues such as insecure code generation, data-leakage pathways, model manipulation, and evolving supply-chain threats. We will explore how engineering teams must adapt their people, processes, and governance models to secure AI-augmented development workflows effectively. The session will then introduce agentic AI as the next evolution in application security—autonomous systems capable of continuous analysis, multi-step reasoning, and real-time remediation. Attendees will learn how combining agentic AI with modern practices can reduce developer friction, improve coverage, and create a future-ready application security strategy designed for the demands of AI-native software development

Dale Gnidovec, Curator of the Orton Hall Museum of Geology at The Ohio State University, will be presenting a program he has wanted to share with us for a long time: Plate Tectonics. His description of his program: Continents on the move - Nothing in Earth history makes sense without moving continents - it tells us why mountains, volcanoes, minerals, and fossils are where they are. This talk examines the evidence for continental drift, why it was disbelieved, and explains how the more-encompassing theory of plate tectonics was developed and eventually proven. Dale is an energetic, incredibly knowledgeable, and very entertaining speaker and this will be another wonderful program by Dale. Hope to see you there! Food and drinks will be provided at the event.
