**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. **QUIET AI STUDIO - WORKING WITHOUT PRESSURE** This is a quiet, non-performative creative working session. There's no sharing requirement and no group activity. You can work privately, sit with your thoughts, or observe how others collaborate with AI. Especially welcoming if you're tired of hustle-style creativity and want a calmer way to move ideas forward. **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.*)**

***Please read all and make sure you agree before you sign up.*** **Court Type:** Outdoor Sand **Level:** adv beginners+/intermediate (BB/A) **Transportation:** Parking will be right by the sand courts, behind the courts, and there is garage parking close to the courts. Metro is the Blue and Yellow Lines. **What to bring:** at least 3 bottles of water and a ball if you have one. **MAX:** 10 players per net. (1 Net) **Restroom:** Restrooms are across the street in the restaurants. **Host's Philosophy on This Event:** The purpose of this meetup is to create a fun and supportive environment where we can improve our skills, enjoy competitive games, and connect socially. While we do aim to play seriously and challenge ourselves, the focus is more on growth and enjoyment than simply winning at all costs. That’s why the title doesn’t include “competitive” or “social”—we want a healthy mix of both. This is a space where you won’t be judged for making mistakes, ***but we do expect you to listen to the organizer if they make suggestions or adjustments***. We also expect a mindset geared toward learning and getting better over time. That said, this event isn’t intended for total beginners; an understanding of the game is expected so that everyone can contribute to meaningful and engaging matches. The host holds the right to remove you from the game if they believe that you are at a C level. **Skill Level:** 1. **If you want to know your level, please see the link below:** [Smiley Social Volleyball Levels](https://docs.google.com/document/d/1PojSi4qdlRsv1msCHhvpQ43iDc4FfzQwpWCc3kafVMY/edit) **YouTube:** The games may be recorded and uploaded to our channel here: Let the host know if you have issues with this ahead of the event. [https://www.youtube.com/@mp02626](https://www.youtube.com/@mp02626) **ATTENDANCE:** **Player Selection:** Regulars > League Members > Smiley Attendance Ratio\* > Skills (BB>B) > New Members The host takes attendance very seriously. Please remove yourself from the event (if you can't make it) as early as possible to allow others to join. You will be marked as a ***no-show*** if you don't show up to the event. One no-show means you will be removed from the group. See the rules below. **\*The organizers can see the number of times you have attended events vs the times you have dropped out. If your drop rate is more than 50%, you may not be accepted to the going list.** [Smiley Social Rules](https://docs.google.com/document/d/1HrG35p_0M08leRvCp8XWG3CMkr_GL928XFabl5T6Dvg/edit) **Q&A** * Bringing your **dog** is welcome and encouraged. * *Can I come if I don't know how to play?* No, you may not. The host teaches a beginner's volleyball class that you may attend on Saturdays. * *Can I be late or leave early?* The host expects you to be there **on time** and leave on time. If you need to arrive late or leave early, please let the host know in advance. * *Can I come even if I am not on the going list?* No, sorry * Why Max the players at 10 when you can do 6v6? This court is already for 2v2; getting 6 players on each side is overkill. * How can I become a regular if I don't ever get to attend? You can attend my other events on weekdays/weekends. Show me you have good skills and bring good vibes! **Smiley Social documents:** 1. [Group Rules](https://docs.google.com/document/d/1HrG35p_0M08leRvCp8XWG3CMkr_GL928XFabl5T6Dvg) 2.

Please join us on **Sunday, March 8 from 4:30 pm to 7:30 pm** as we head back to **[Mookie's BBQ](https://www.mookiesbbq.com/index.html)**, a venue in Virginia, in support of a fellow meetup member. This is a bonus meetup outside of our normal weekday meetups. **Please RSVP to indicate your attendance and HONOR YOUR RSVP**. If your plans change and you are unable to attend, please update your RSVP particularly since this venue has limited space. Regular no-show or late notices may get you dropped from the group. It is important that we are able to provide an accurate count to the venue and that all people who want to AND are able to attend are able to do so. **We ask all attendees to pay $1 to participate in the meetup.** This money helps maintain our meetup membership & cover various meetup costs that arise. You can pay $1 on Venmo @amanda-uherek, via Pay-Pal, or in-person (please choose paying friend/family not a business, good or service). **REMINDER:** everyone is responsible for their own tabs. If you have questions / comments / suggestions please message us. We'll have hand sanitizer & decks of cards on hand. Cheers - Amanda

This month, we'll have a recorded talk, followed by discussion, on API design and single-header libraries. How should we structure and program libraries to impose as few usage constraints as possible? We’ll look at [the STB libraries](https://github.com/nothings/stb) and other examples as case studies. We're still at the West End Library - see the location in the sidebar for details. **Agenda:** \- 2pm \- 3pm: Library discussion \- 3pm \- 4pm: Open\-ended discussions\, presentations\, etc\. \- 4pm \- whenever: We'll go get food nearby\! **What we do** Presentations on lower-level, foundational programming topics, ethical software, knowledge sharing, mentoring, and discussion. **Who we are:** We are all about handmade software. Rather than focus on frameworks, heavy abstractions, and buzzwords - we typically create projects or research topics that build an understanding of foundational computing concepts, essential data structures, and hardware/software interaction. **What to bring?** Bring a laptop, project, or just a curious mind. If you're not sure you're ready to contribute, don't worry: we're all here to share our passions and hone our craft. **If you arrive late:** Please enter the room quietly as to not disrupt anyone that is presenting. You can take any empty seat.

Title: What Is Space Density? From Medium Ontology to the Spacetime Constant K Date: March 8 2026 10:00 am - Noon EDT Abstract: Spacetime plays an active role in gravity, wave propagation, and quantum behavior, yet physics rarely treats it as a physical medium with intrinsic properties such as density or inertia. This missing layer creates a major conceptual gap—especially when interpreting large-scale gravitational anomalies that are often attributed to dark matter. In this talk, Lynn will propose a clear conceptual framework for what it means for spacetime itself to possess a density-like property, and Lynn will explain why Unified Field Theory (UFT) naturally encodes this property through the constant K, called the spacetime background inertial intensity constant. Lynn will introduce a space-density constant μₛ as a universal property of space itself—independent of matter, energy density, or gravitational sourcing. However, μₛ cannot be inserted directly into field equations, because it belongs to the ontological level: it describes what space is, not how spacetime responds. To influence dynamics, μₛ must be expressed geometrically. This leads naturally to K, which carries the same physical meaning but operates at the level required by geometric field dynamics. This is a change in representation—not the addition of new physics. This approach provides an alternative way to interpret dark-matter-like effects. Instead of requiring unseen particles, gravitational anomalies can be viewed as consequences of spacetime’s intrinsic rigidity and its global, cumulative response in large coherent systems such as disk galaxies. In local, weak-field environments, standard Newtonian and relativistic gravity remains an effective approximation. The goal of the talk is not to present a final empirical model, but to clarify the physical meaning of spacetime constants and open discussion between UFT and mainstream theoretical physics. Keywords: Spacetime ontology; space density; intrinsic spacetime properties; Unified Field Theory (UFT); spacetime background constant K; geometric response; gravitational coupling; dark-matter-like phenomena Brief Biography Lynn Lou Beran is a Senior IT Security Analyst and an author, translator, and editor working at the intersection of science, engineering, and communication. She translated and edited multiple editions of Zhang XiangQian’s Unified Field Theory and co-authored recent manuscripts developing a geometric, motion-based view of physical reality. Lynn’s broader work focuses on making advanced ideas accessible without sacrificing rigor, and on connecting conceptual insight to testable predictions and practical tools.

Alright Beavers, it’s time to emerge from the lodge and get back on the pitch! Practice is officially back this week, and we’re capping off the first week with a session that is—quite literally—a big deal. We’ll start with a **fun touch session** to shake off the rust and work on our ball handling. After we’ve built up a proper thirst, we’re heading straight to **Audacious Alewerks** for a post-practice social. **Why you shouldn't miss it:** It happens to be **Pickle Day** at the brewery! Since we’re Beavers, we usually stick to wood, but this Saturday we’re making an exception for some fermented cucumbers. **The Game Plan:** * **Touch Rugby:** Fast-paced, low-contact, high-fun. 🏉 * **The Weather:** Looks like it will be a wonderful warm and sunny day! * **The After-Party:** We’re heading to Audacious Alewerks in Falls Church. * **The Goods:** They are bringing back the **"Kind of a Big Dill" Pickle Gose Ale**. If beer isn't your thing, they’ve got **pickle martinis**. * **The Grub:** **Bad Ass Pickles** will be there from Noon–4:00 PM doing tasting flights. Word on the street is they go great with grilled cheese. **The Details:** * **When:** This Saturday, March 7th. * **Where:** Larry Graves Park then Audacious Alewerks. * **RSVP:** Do it now. Let’s kick the season off right. See you on the pitch!

ike Turkey Run Park- Pho Lunch, VA Sunday March 8 With winter weather receding, this is a great way to fight cabin fever and head back outside with views of the Potomac. This is a 3 to 4 mile loop hike along the Potomac River just below the American Legion bridge off the GW parkway. The trail is mostly easy and flat, but there are some slightly rocky areas. Be aware that this time of year where segments along the river can be muddy and there are some rocky areas we must maneuver around. Bring a mascot! The park is dog-friendly, but must be on a leash. For more info and maps (see side links): [https://www.nps.gov/gwmp/planyourvisit/turkeyrun.htm](https://www.nps.gov/gwmp/planyourvisit/turkeyrun.htm) What to Bring: Good hiking shoes Water Meet: 9:00 am Where: Parking Lot C-1. (First parking lot when entering park. See map at link below for details) Park Trail Map: [https://www.nps.gov/gwmp/planyourvisit/upload/Corrected-Turkey_Run_Park_Trail_Map_11242023_508c.pdf](https://www.nps.gov/gwmp/planyourvisit/upload/Corrected-Turkey_Run_Park_Trail_Map_11242023_508c.pdf) Departure: 9:10 sharp. We should return to the parking lot no later than 11:15 am. For those interested, we can later head over to nearby Pho 75 (1721 Wilson Blvd) for a great hot pho - one of the best in the area. **Note: Cash Only!** **In the comments section please indicate if you need a ride. If you are coming by car and wouldn’t mind picking someone up at a convenient metro stop, please indicate how many people you can take. Hopefully we’ll have enough room for everyone. I can pick up three at the Braddock Road metro (yellow), located in Alexandria, VA. Or, I can pick up folks at Rosslyn metro (orange/blue). Carpoolers, please chip in generously for gas.** Note: This event is cross-posted with other Meetup groups.

**Agenda:** * 6-6:30 pm: Networking and food/drinks * 6:30-7:15 pm: Announcements and presentation * 7:15 pm-7:30 pm: Q&A and close-out **Hacking the Stack: Using OpenSearch Dashboards as an Application Framework** Most developers treat OpenSearch Dashboards (OSD) strictly as a visualization layer—a place for charts and graphs. They are missing the bigger picture. OSD is a powerful, untapped environment for full-stack application development. In this session, we peel back the architecture of **an enterprise-grade risk, compliance, and security platform built entirely *on top of* OSD**. We moved beyond simple plugins and pushed OSD to its limits to create a seamless, interactive application experience. Join us for a deep dive into the engineering reality of the OpenSearch stack, including: * **The Analysis:** Why the OpenSearch stack beat out the competition. * **The Build,** **Beyond Visualization:** How to implement custom React components to build complex workflows and interactive UIs within OSD. * **The Integrations:** Integrating Wazuh for agent management and ingesting data at scale. * **The “Gotchas”:** Honest, real-world lessons on data handling, state management, and what to look out for. **If you are ready to push your plugins from “reporting tools” to “robust software,” do not miss this session!**

This training is designed for real estate agents who want to learn how to play the Agent Investor game. The goal of this training is to help you flip your income into ownership. ━━━━━━━━━━━━━━━━━ **Traditional buyers transact once every 7–10 years. Investors transact 3–10 times a year.** If you want predictable income, consistent deal flow, and a long-term wealth ecosystem, you don’t need more leads—you need a better list: a database of committed investors who buy repeatedly. The Investor Goldmine teaches you how to build, grow, and activate an investor database that becomes your most valuable asset in real estate. Instead of competing for one-time transactions, you position yourself as the Agent Investor—someone who understands strategy, leverage, and wealth building. In this session, you’ll learn the proven systems to build your investor list from scratch, including: * Where to network to meet real investors already buying * A simple “one lunch a week” strategy to build relationships fast * How to use giving and social currency to become the trusted connector * How absentee owners and business owners can become your best investor pipeline * Why community accelerates database growth—even if you don’t run one You’ll also get a clear activation plan to start growing and converting your investor database immediately. Because the model is simple: Build the list. Call the list. Market to the list. And your income becomes repeatable. ━━━━━━━━━━━━━━━━━ **Did you miss it?** [Watch all GRID Reston event playback on YouTube](https://www.youtube.com/playlist?list=PLOTh5kxLLJI1G3VH6Pqhlhu0uTA8yrdpi) ━━━━━━━━━━━━━━━━━ **Join the GRID Facebook Community** [Join the online GRID community here](https://www.facebook.com/groups/gridinvestor) to post deals, ask questions, and connect with other investors across the globe.
