**This talk has completely sold out in advance and no door tickets will be available. You can catch the same talk at Highline RxR on March 15th, when plenty of tickets remain for sale.** [Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“Celtic Mythology,”** an exploration of the beliefs of a people whose influence spread far beyond the British Isles, with Larissa “Kat” Tracy, past president of the American Society of Irish Medieval Studies, former editor of its journal, *Eolas*, and visiting assistant teaching professor of English at the University of Maryland Baltimore County. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-celtic-mythology](https://events.ticketleap.com/tickets/profsandpints/dc-celtic-mythology) .] The Celts inhabited lands stretching from the British Isles to parts of France and the Holy Roman Empire. Their influence can be seen in the art of the Vikings, in the rich oral and literary traditions of the Irish, Welsh and Bretons, and in the modern renaissance of Celtic culture. But who exactly were they? Get into the minds of the Celtic people by learning about their myths and beliefs with Larissa “Kat” Tracy, a scholar of Old and Middle Irish and Middle Welsh language and literature and published translator of Old Irish texts whose dynamic and fascinating talks have earned a considerable following among Profs and Pints fans. Dr. Tracy will delve into early medieval literary records that tell stories of the Tuatha de Danann, a godlike people who invaded Ireland and then were defeated themselves. She’ll offer a new perspective on faeries, banshees, and leprechauns by describing how the ancient Otherworldy people once believed to inhabit the western realms of Ireland were diminished or demonized into figures of popular folklore. You’ll learn how the ancient God of the Sun become one of the “little people” guarding cauldrons of gold and bestowing luck, how immortal beings of majestic stature shrank to small winged creatures in the back of gardens, and how supernatural women associated with the “people of the mound” became screaming harbingers of death. We’ll explore how medieval literary texts inspired later legends and became adapted into folklore. You’ll gain an understanding of how the medieval Catholic Church’s growing power led local people to reimagine their ancient gods and goddesses as Christian figures like Saint Bridget and Saint Patrick. You’ll gain an appreciation of how the Celts gave rise to living traditions that survive in modern popular culture through the preservation of languages, storytelling and music enjoyed all over the world, and renewed interest in goddesses like Brid and celebrations like Samhain. (Doors: $17, or $15 with a student ID. Listed time is for doors. The talk starts 30 minutes later.) Image: From “Riders of the Sidhe,” a 1911 John Duncan painting of the Tuatha Dé Danann.

We're back. Brisk, 3- to 4-mile urban hike starting and ending at Whitlow's on the Wharf. We will hike around Hains Point before looping back to Whitlow's for drinks and food. Rideshare or public transportation recommended, closest metro L'Enfant.

Side projects are how a lot of us learn new tools, explore ideas, and connect with people—and they're a lot more fun when you have other people to talk to about them. **Schedule (this might change!!!)** * ​6:00 - 6:30PM: Mingling & food & drinks * ​6:30 - 7:15PM: Lightning talks * ​7:15 - 8:00PM: Networking & social hour Speakers! * **Travis Hoppe** (speaking in personal capacity): "Girls, Interrupted" — using face detection and embedding models to analyze screen time across 175 movies * **Elliott Miller**: "Binding at the Speed of AI: LoRA Training Meets Autonomous Agents" * **William Zhu**: [MoltComics](https://moltcomics.com) — Comics for the Agent Internet * **Mystery speaker** (speaking in personal capacity): Congressional side projects you can do.

**Schedule** 5:00 pm - 5:30 pm - Sign-in/Meet and greet/networking 5:30 pm - 7:00 pm - Break the Cloud Lock-in: Building Adaptive Intelligence Orchestration with DIO 7:00 pm - 7:45 pm - Leaning on the SQL: Crafting Resilient Data Layers **Talk and Speaker Details** **Time**: 5:30 pm est. **Title**: Break the Cloud Lock-in: Building Adaptive Intelligence Orchestration with DIO **Summary**: AIaas are often stuck in a binary choice: pay the "token tax" for convenient Cloud APIs or manage the complexity of local open-source models (Llama/Mistral) yourself. The future belongs to a hybrid architecture—but the routing logic shouldn't be spaghetti code. In this session, we introduce DIO (Distributed Intelligence Orchestration), a new open-source framework designed to bridge on-premise infrastructure and cloud capabilities. We will move beyond theory and look at the code behind the Federated Decision Engine (FDE)—the algorithm that allows you to dynamically route prompts based on privacy, cost, complexity, and more. **Session Takeaways:** \- The DIO Architecture: A technical deep dive into the open\-source framework that decouples your application from specific model providers\. \- Live Integration: How to implement the DIO SDK to build a "Smart Router" that connects the best of both world for Cloud & On Prem Intelligence\. **Speaker**: Snow Zhao **Speaker Bio**: Founder & CEO of AIgentic \| Ex\-Meta engineering leader\. Building the future of professional services with precision & trust\. Snow has decades of Silicon Valley experience building and scaling technology organizations at Facebook, Block (Cash App), and Groupon. She is currently building at AIgentic, an applied AI company designing robust, trustworthy AI systems for professional industries. She leads global teams that delivered secure, high-performance systems used by billions, from product infrastructure behind Messenger’s rewrite and end-to-end encryption, to architecting enterprise AI platforms that bridge traditional sectors with digital transformation. Her work has spanned mobile, security, open-source, federated architecture, AI-powered automation, cross-platform software ecosystems, and more — always guided by the principle that engineering excellence is a human discipline as much as a technical one. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **Time**: 7:00 pm est. **Title**: Leaning on the SQL: Crafting Resilient Data Layers **Summary**: Most apps need to persist data. The mechanisms for persisting vary, from key-value pairs to relational databases to files and more. SQLite is the de-facto standard for persistence in mobile apps: it ships with every Android and iOS app. This session looks into best practices for SQLite data persistence, drawing from practical, digestible, real world examples. We look into when one should lean on the SQL versus when to perform data manipulation in application code. We look at some examples of constraints that you might have written in Kotlin/Swift, and how expressing them in SQL instead can offer data consistency and integrity benefits. A major focus of the session is on migrations. Data schemas inevitably evolve, and executing migrations carefully is essential, as mistakes can have severe consequences, including data corruption. We look into best practices for migration, including when to do migration in application code versus in SQL. We also examine some real world migration examples beyond the simple case of adding a column with a default value. Finally we look at migrations that cross data sources. This could occur if for example you were persisting data in a key-value store but you now want to migrate that to a database table. This must be done in application code but can you still take advantage of database migrations? Can you cover your migration code with unit tests? **Speaker**: Kiran Raon **Speaker Bio**: Two decades as a developer, got into Android in 2010. Adopted Kotlin in 2017, had my first attempt at KMP in 2019 (when it was still called KMM). Worked on and off with iOS and web client technologies throughout my career, also dabbled in other cross platform technologies.

In March of 2026, the long-time staple of Kubernetes ingress controllers, ingress-nginx, will stop receiving security patches and regular updates. For many Kubernetes operators, this is a forcing function for us to migrate to a new solution that supports the newer Gateway API. The ecosystem of solutions in this space is large and complex, and operators find themselves weighing a myriad of options. In this talk, I hope to answer many questions that we have had to answer in this space, such as: * What are the advantages of Gateway API over the Ingress API? * Which Gateway API Solution should you use for different scenarios * Why not simply migrate to another ingress controller? * Where does the AWS Load Balancer Controller fit in this new ecosystem? * What does support for WAF, ALB, NLB, etc. look like going forward? **Timeline:** **6:00 PM** \- Doors Open\. Please be prepared to show ID that matches your registration\. **6:30 PM - 7:30 PM** \- Speaker **7:30 PM - 8:00 PM** \- Networking **8:00 PM** \- Event ends\. Conversation continues at Highline for anyone interested\.
