Domain Driven Design

If you’re a dad over 35, you probably feel it: * Your energy isn’t what it used to be. * Work stress drains you before you even get home. * The weight has crept on around the middle. * Your kids still have endless energy, but keeping up with them feels harder every year. And deep down, you know your family looks to you as the example. If you’re running on empty, short on patience, and out of shape, that’s the standard you set at home. The **D.A.D.S. Program (Dads Achieving Discipline & Strength)** was built for men like you. Ordinary guys with jobs, families, and full schedules who want to: * **Reclaim strength** so you feel capable, athletic, and confident again. * **Boost energy** so you’re sharp at work and fully present with your family. * **Drop the aches, stiffness, and sluggishness** that make you feel older than you are. * **Find balance and accountability** by training alongside other dads in the same fight. * **Crush male loneliness** by connecting with men who “get it” and have your back. Here’s the best part: You don’t need to be a seasoned gym rat. This is designed for **beginner to intermediate exercisers**—dads who may have been out of the gym for years or have never had a structured program, but know it’s time to get serious. Monday, Wednesday, and Friday mornings, we’re hosting **Meet-Up Workouts from 6:00–6:45 AM.** No strings attached. Just one powerful hour that could be the turning point in your health, energy, and family life. There are only **8 spots available**, and once they’re gone, they’re gone. Location: Revolutionary Fitness - 215 N. Payne St., Alexandria, Va 22314 Every Monday, Wednesday, & Friday from 6:00–6:45 AM To claim your spot, call/text 703-783-2316 or email sign up directly at [https://go.thefitrevolution.com/dads](https://go.thefitrevolution.com/dads) Stop putting yourself last. Take this hour, and give your family the stronger, sharper, healthier version of you.

We’re still working to get more people into these Meetups, but our goal is to give PlayYourCourt members a few social tennis outings each week in addition to your practice sessions and Challenge League matches. These Meetups are co-ed, super laid back, and all skill levels are welcome. Post your skill level and a suggested court in the comments section so we can round up as many players as we can for some tennis fun! Also, if you’re looking to meet new practice partners or play some matches and you aren’t already in the PlayYourCourt Community, you can go here to see what we’re all about and sign up: https://www.playyourcourt.com/tennis-community/alexandria-va/meetup/ If you love tennis, we’d love to have you! Be sure and watch the quick video that explains how everything works. Happy hitting! - Scott

**AI-Supported Creative Exploration** *For Unassuming Intuitives & Practicing Creatives* (Please note that this event has not been organized or endorsed by The Writer's Center.) This meetup is part of AI as Creative Partner — A Practice Group, a set of open, non-sequential creative labs you can join at any point. We use AI as a thinking partner—not to replace your ideas, but to help surface and shape them without overthinking or pressure. You bring fragments—ideas, impulses, unfinished concepts. With AI as a supportive collaborator, we explore how those fragments can become clearer, more coherent, and ready to share if and when you want to. No technical background is required. If you can talk or type, that's enough to work with AI here. This session is intentionally low-commitment and flexible: * Arrive late or leave early * Work quietly or observe * Ask questions, or simply watch the process unfold There's no presentation and no expectation to finish anything. Showing up as you are is enough. **THINKING OUT LOUD WITH AI - LIVE WORKING SESSION** This session is for people curious about how creative thinking actually happens with AI. I'll be working live on my own project, narrating decisions when useful, and answering questions as they come up. You're welcome to work on your own project, watch quietly, or ask about the process. No experience required. (Please note that this event has not been organized or endorsed by The Writer's Center.) **HOW TO FIND US** Look for the room with the door open on the lower level. Look for the guy with the screen projector and ambient light and sound. Feel free to just walk in and settle. **(*This is an independent meetup using rental space at The Writer's Center. The Writer's Center has not organized or endorsed this event.*)**

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.

This is a substitute hike for the one originally scheduled for Indian Head Rail Trail on Saturday. The location was changed due to icy trail conditions at Indian Head and was rescheduled due to severe wind chills forecast for Saturday. The conditions for Sunday, Feb. 8 are better, though far from ideal. Winds will be from the northwest at about 15-25 miles per hour. The temperature will start out around 17 degrees Fahrenheit (about 2 degrees F wind chill) and gradually rise to about 22 degrees F (about 10 degrees F wind chill). Therefore, you must dress in multiple layers (avoiding pure cotton next to the skin), have winter head and ear coverings, and winter mittens or gloves. You’ll need to show these items to a leader before signing the waiver form and in order to participate. A winter scarf is also recommended to partially cover your face. The reason for layers is that the air between them provides extra insulation and you can remove some layers if needed to prevent overheating during exercise; the idea is to retain warmth with minimal sweating. Bring water and snacks as there will be no organized lunch stop. No pets please. We’ll meet at the Braddock Road Metro station by 10:00 AM Sunday. We urge you to take Metro rather than driving because finding a legal parking spot is difficult. We should meet in the vicinity of bus bay E just outside the Metro station. To simplify registration, we’re waiving collection of donations for this event. The route will be along city sidewalks and trails that have been sufficiently cleared of snow and ice, with very few exceptions. Two public restroom locations are available, one at about the 2.2-mile mark, and one at about the 4.9-mile mark, but there are a number of businesses along the way where you can use their restrooms if you buy something there. King Street Metro station is an optional bail-out point at 4.8 miles. The hike ends back at Braddock Road Metro. Paper handouts of the route will be available at the start, so please change your RSVP if you decide not to attend. Execution of a Sierra Club liability waiver is required at the start. You need not be a Sierra Club member to participate, but if you'd like to join, go to: [http://www.sierraclub.org/virginia](http://www.sierraclub.org/virginia) . Leaders: Gary Kosciusko, (703) 946-8111, and Vicky Hsu. Although open to all, this hike is part of a series of Saturday training hikes leading up to the [One Day Hike](https://www.meetup.com/sierrapotomac/events/304791832/) (ODH)—a 100 or 50 km hike along the C&O Canal—on May. 2, 2026. See SCPRO’s [Meetup page](https://www.meetup.com/sierrapotomac/) for other training hikes as they are posted. If you would like to support the ODH, see [volunteering opportunities](https://www.meetup.com/sierrapotomac/events/304792694/) and/or contact Mike Darzi ([mike.darzi@gmail.com](http://mike.darzi@gmail.com/)).

***Arcs*** is a sharp, tactical space opera game, for 2–4 players, set in a dark yet silly universe. Players represent officials from a distant, decaying and neglectful Empire who are now free to vie for dominance whether through battle, gathering scarce resources or diplomatic intrigue. Ready yourself for dramatic twists and turns as you launch into this galactic struggle. A deck of cards in 4 suits with ranks from 1-7 (2-6 for fewer than 4 players) defines the action selection system. These cards are played in a trick-taking adjacent system to select actions, take the initiative and declare Ambitions. The 3 declared Ambitions are what will score in that deal. Timing is everything. Bad hands must be mitigated by careful card play and benefitting from other players' card play. Battles are resolved quickly with the attacker choosing their level of risk. The defenders must be prepared with adequate defensive ships and cards in their tableau.

### Tools in your AI's Toolbox : An introduction to MCP Servers The generative AI revolution has unlocked unprecedented capabilities, but the next frontier is agency: empowering models to interact with, query, and act upon the world. The current challenge is the “N x M integration problem,” where every AI model requires a custom, brittle integration for each external tool or data source. This approach simply doesn’t scale. How can we give an AI access to our sales leads, code repositories, or IoT devices in a standardized, secure, and reusable way? This session introduces Anthropic’s Model Context Protocol (MCP), the open-source framework designed to solve this challenge and become the universal connector—the USB-C port—for AI. MCP standardizes how AI models discover and use external tools, moving beyond simple function-calling to a robust, client-server architecture. We will dive into how this open protocol is creating a new ecosystem for building powerful, context-aware AI agents. Join this session for a developer-focused introduction where you will learn how to: Understand the core concepts of the open-source Model Context Protocol and its architecture. Utilize pre-built, open-source MCP servers to instantly connect AI to tools like Git, Slack, and databases. Build a custom MCP server to securely expose your own proprietary data and APIs as tools for any compliant AI. Move beyond bespoke integrations and contribute to a standardized, collaborative, and open ecosystem. Stop building one-off connectors and start building intelligent agents. This session will give you the practical knowledge to leverage MCP and create the next generation of AI that doesn’t just talk, but does.
