Valentine's Day might be in the past, but Plato's classic discussion of love and desire, the *Symposium*, is eternal. Join us on April 4 to discuss this famous work, which features Socrates, Alcibiades, and other important Greek figures at a drinking party where things quickly turn philosophical. Feel free to bring whichever translation you prefer. As usual, we will meet in the Martin Luther King Jr. Memorial Library in the **205-B Accessibility Room**, located on the second floor.

Hello everyone, Badminton at Chinquapin! See you there! Aditya

**Trail Map / VA Bus** *$36. Long hike: 12 mi., 900 ft. elevation gain. Moderate hike: 8 mi., 500 ft. elevation gain. Extra-long hike: 18½ mi., 3000 ft. elevation gain.* There are literally acres of Virginia Bluebells on the banks of Bull Run, the result of rich, seasonally flooded, sandy soil. If the season's timing cooperates, we will see vast stands of these flowers in full bloom. Trout lilies, beavers, heron, kingfishers and migratory warblers also vie for attention. Moderate hikers start at Hemlock Overlook and proceed north (upstream) on the Bull Run – Occoquan Trail to Bull Run Regional Park. Long hikers start hiking north from Bull Run Marina. Hikers who are up to the challenge have the option of starting at Fountainhead Regional Park to cover the full length of the trail. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- RESERVATIONS Capital Hiking Club is a non-profit group, and the public is invited on all trips. Reservations are accepted as late as Friday, but reserving before Wednesday night helps ensure your spot and prevent cancellation of the hike due to low sign-ups. RSVP through Meetup and pay through PayPal. Please be sure your RSVP gives your full name and phone number and where you'll be boarding the bus. We don't want to leave you behind! FIRST-TIME HIKERS If you're a first-time hiker with us, please notify the leaders in advance so they can make sure you have the info you need. Hikers must be able to keep at least a 2 mph pace.

**Location**: Tysons-Pimmit Regional Library (Virginia) Conference Room A game development **Working Session** involves 3 key parts: 1. Tell people what you're going to do 2. Actually do stuff 3. Show people what you did That's what we'll be doing for this meeting. We'll briefly tell each other what we're going to do, then work on our projects, then at around 5:30 wrap up to show each other what we did and chat for a bit. You don't have to stay the whole time, so feel free to drop in and out as you have time. All game development skill levels welcome. Whether you're bringing a game you're trying to ship in a month, or you're just planning on following some tutorials or trying out a new tool to improve your skills, use this time to make progress. Working sessions also train you to think about the scope of your work: pick a chunk of work that you can complete in the time that we have. That way you can end the working session with a feeling of accomplishment! **What to bring**: Laptop, Charger, maybe a power strip if you have one handy, any other game development tools you need. Try to download any software you need before the working session. There is Wifi at this location, but it may be slow if you have to download any large files.

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.

Pay attention! We’re delaying a week for those of you who may be on Spring break and/or celebrating the holiday. Ok, no pancakes, but waffles-a-plenty. Join the local UX and Digital Design community for a casual monthly breakfast. Look for us upstairs!

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 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.
