Friday soccer in the West Potomac Fields (by Ohio Drive) late afternoon
Join us for a pickup on a weekday! There will be little wet field but we still plan to play. Group is relatively small which means you will get to show your skill and run quite a bit ! It is a co-ed game and open to all. Once the players limit is reached, no player will be admitted into the game. We already got a number of players (10) confirmed OFFLINE as guests of Host(s) through Signal. *Those in waitlist will be moved to the confirmed list only when spot becomes available.* *Also the games RULES below, fair play and camaraderie must be followed*. ⚽ It is a friendly game, no slide or back tackling, no rough play, and no greedy play or coaching. ⚽ Join the **Signal group**, Download ***[Signal app](https://signal.org/download/)*** and ***[join the Signal group](https://signal.group/#CjQKIBolYKIpshcX_ooOu_fmV7xlbEeJm5zBZ6_V8uTiuFNOEhAk5KeXU1QFVt39OBRP106d)*** for the game day updates. *Firstcomer, SEE the host to approve you to join the group*. ⚽ No groupism or favors, everyone gets to play without regard for the level be it starter, intermediate or advanced. One must pass ball to appropriate fellow players without favors or preference to a particular player(s). ⚽ It is expected to change positions, no one is permanent striker or defense, make sure you circle around and give chance to everyone to experience the game fully. ⚽ Bring WHITE as well as DARK jersies (and ball too if you can). ⚽ Send DM to host(s) on Signal if you have questions. ⚽ Look out for the changes in location of the field in case we would have to change the field. ⚽ Change your RSVP if needed. More than two no shows after RSVP will be banned for next games. If you need to cancel, do so at least 3 or 4 hours before the game. We do not want to have a low turn out due to last minute cancellations or no shows. ⚽ Additional guest must RSVP themselves to ensure personal accountability in case of no shows. ⚽ We typically post the updates on Signal and MeetUp. We may get some players confirmed OFFLINE so it is likely we may get at least 8v8. We limit the RSVP slots to avoid being a large group. If we will have enough players, we will have second game too. Be mindful of heavy traffic on the day and parking challenges of a typical city! Text 510- 394 29 three nine if have any question unanswered from above.
MP(FRI)-Sand Volleyball: BB - Crystal City
MP(FRI)-Sand Volleyball: BB - Crystal City
***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.

What Is Space Density? From Medium Ontology to the Spacetime Constant K
What Is Space Density? From Medium Ontology to the Spacetime Constant K
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.

Hike Turkey Run Park (Easy/Moderate) – Pho Lunch
Hike Turkey Run Park (Easy/Moderate) – Pho Lunch
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.
Sunday Chevy Chase Morning Game
Sunday Chevy Chase Morning Game
THIS GAME IS BASED ON AN OLD GAME , SO MOST OFTEN YOU WILL NOTICE THAT PEOPLE ( THE FOUNDERS) ARE ADDED BEFORE THE RSVP EVEN OPENS. After that, few spots are available for first reserves and the Host has the right to choose the added people from the wait list (Based on dependability, punctuality and cooperation) ***No wait list show ups*** No-shows will be taken seriously and you lose your privilege to RSVP the next game. This is an early game, so you have to cancel the night before. If you cancel late, it will be considered no show. Please wear turf shoes (no cleats) in this field. Please use a clear profile picture so it is easier for us to know each other. if you don't have a clear picture, the host might cancel your rsvp. If you plan on playing with us , keep in mind we collect yearly donations (Collected once a year ,$25). You can zelle me (3189143325) or Venmo(@Aladdin-Alayoubi) or give cash.
Meetup #16: API Design & Single-Header Libraries
Meetup #16: API Design & Single-Header Libraries
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.

CBusData - Discover the Power of Window Functions
CBusData - Discover the Power of Window Functions
Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.

Bad Girls Book Club March 2026
**Our March pick is *God of the Woods* by Liz Moore.** **This month’s novel is an award-winning literary mystery that blends family drama with psychological suspense. It explores women’s voices and relationships while delivering an exciting, eerie, and deeply suspenseful story. The book is 576 pages in print or 14 hours and 35 minutes on audiobook.** Early morning, August 1975: a camp counselor discovers an empty bunk. Its occupant, Barbara Van Laar, has gone missing. Barbara isn’t just any thirteen-year-old: she’s the daughter of the family that owns the summer camp and employs most of the region’s residents. And this isn’t the first time a Van Laar child has disappeared. Barbara’s older brother similarly vanished fourteen years ago, never to be found. As a panicked search begins, a thrilling drama unfolds. Chasing down the layered secrets of the Van Laar family and the blue-collar community working in its shadow, Moore’s multi-threaded story invites readers into a rich and gripping dynasty of secrets and second chances. It is Liz Moore’s most ambitious and wide-reaching novel yet.
