James is out of town this week, so let's draft my variant of the famed 100 Ornithopters cube, featured in [this video by Rhystic Studies](https://www.youtube.com/watch?v=Pddm1gbBuWE). My list is slightly different, but keeps the same design philosophies, although there might not be exactly 100 Ornithopters. The cube has no creature tokens, no creature lands, and no ways to kill your opponent without the card having something to do with controlling or having Ornithopters. My cube list is below: [https://cubecobra.com/cube/list/100ishornithopters](https://cubecobra.com/cube/list/100ishornithopters) The event will take place at a **NEW LOCATION** in Arlington, near Ballston Quarter, and the Ballston metro, accessible through the Orange and Silver lines!

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“The History of Plastic Surgery,”** with Dr. Wendy Chen, plastic, reconstructive, and hand surgeon and assistant professor at the Johns Hopkins School of Medicine. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-plastic-surgery](https://events.ticketleap.com/tickets/profsandpints/nv-plastic-surgery) .] Most people misunderstand plastic surgery as vain and aesthetic, but the origins of this fascinating specialty are much deeper than that. Come gain a rich understanding of the roots, medical impact, and current wide reach of a life-altering medical specialty with Dr. Wendy Chen, a leading educator on plastic and reconstructive surgery who has won awards for her work in clinical, basic science and education research. She’ll talk about how reconstructive surgery has been around for thousands of years, with evidence of it having been practiced in ancient Egypt and India, and has made advancements in the course of major wars. Those who practice it have been innovators in medicine, playing a major role in breakthroughs and winning the Nobel prize for kidney transplantation. The need for plastic and reconstructive surgery has stemmed largely from how much our appearance influences how we navigate our worlds and how others regard us. There was a time, in fact, when people in American prisons were offered plastic surgery as an intervention against recidivism. Yet reconstructive surgery also has faced opposition, such as religious bans on its practice stemming from the belief that physical differences are a manifestation of spiritual sin. Fast forward to now when plastic surgeons treat patients of every age for every kind of ailment, from congenital differences to trauma to cancer. Yes, some plastic and reconstructive surgery is to help people conform to tabloid- and social media-driven narratives of what defines beauty, but the field involves a lot more than injecting Botox and shaping buttocks. ( Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.)

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“What Digital Detectives Find,”** on the afterlife of your digital data and the methods of those who investigate it, with Jim Jones, associate professor at George Mason University and cyber security and digital forensics expert. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-digital-detectives](https://events.ticketleap.com/tickets/profsandpints/nv-digital-detectives) .] What happens when you delete digital data such as a picture, video, or email message? The truth is that “deleted” doesn't mean “gone,” and digital forensic investigators can extract and make sense of the residual fragments left over from data often assumed to be gone forever. Learn about the field of digital forensics—and the lessons it offers those who worry about sensitive data being exposed—with Jim Jones, who has been a cyber security and digital forensics practitioner, researcher, and educator for more than 30 years. You’ll learn how all investigations today, criminal and otherwise, to some degree involve digital forensics, an interdisciplinary field that draws from computer engineering, computer science, information technology, law, and ethics. Digital forensics doesn’t just respond to specific incidents, but also seeks out threats within organizations, analyzes malware, and buttresses cyber security. Much of the work of Dr. Jones, his colleagues, and students involves examining digital systems of all types to understand how data persists and decays and how it can be found and recovered. Dr. Jones will discuss how what happens to the digital data that you deleted depends on the type of device you are using, along with a host of other factors. You'll learn how digital data is stored on different devices and what does and doesn’t happen when you delete that data. You'll see examples of data extracted from different devices, demonstrations of what can be inferred from these remnants, and how investigators can tell if such remnants are genuine or not. Finally, you'll learn about strategies to mitigate the risk of exposing sensitive data. Dr. Jones will sort those that work from those that don’t. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.) Image: A digital forensics examiner works with evidence in the FBI’s New Jersey Regional Computer Forensics Laboratory (FBI photo).

SAM BASU IN-PERSON; NOTE: THIS IS THU, NOT TUE AS NORMAL Code is cheap, but software is expensive. Modern AI is a big opportunity to streamline and automate developer workflows for better productivity. There are some challenges though – AI Models often lack knowledge and AI Agents need expertise/guidance to reliably pull off complex workflows. Context is everything for modern AI and you can bring it. Model Context Protocol (MCP) aims to provide a standardized way to connect AI Agents to different data sources, tools and non-public information - the point is to provide deeply contextual information/expertise to AI. Skills are higher-level behaviors and instructional guardrails, that define how and when AI Agents should leverage tools to accomplish something meaningful. Subagents in AI are specialized, task-focused agents designed to handle specific, well-defined tasks within a larger AI system. In terms of the food industry: AI Agent = Chef 👨‍🍳👩‍🍳 MCP Tools = Raw Ingredients 🥔 🥩 Skills = Recipe Cards 📝 📇 SubAgents = Sous Chef 🔪 🍳 Loops = Door Watcher 💂👀 Developer = Restaurant Owner 👑. So, what should developers use to bring context and guardrails to make AI work their way? Well, it depends and sometimes, the answer might be whatever combination makes developers most productive. With official SDKs and well-thought-out guidance, it is a breeze to work with MCPs, Skills or SubAgents. Developers could bring their own data, APIs, services, coding patterns and structured guidance to make AI Agents work their way. And AI Agentic workflows work the same way in IDEs or Terminals, paving the way autonomous ways of getting work done with AI. With contextual expertise to light up unique coding workflows, AI Agents can make developers ultra productive – upwards and onwards.

**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.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** GitHub Copilot is powerful, but what if you could scale from a solo AI assistant to an entire team of specialized agents working in parallel? This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD

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.
