_Games this month:_ the birds and the bees! Wingspan, Apiary, and more! **A note from the organizers:** We see that this is becoming a popular event and so there's not a ton of space available for general non Patreon members rsvp'ing via meetup. Space is limited by how many volunteers we have to host games each month, and first access goes to the members of the Patreon who support everything DCGG does. We have the goal to train and provide additional staff for this event as we gain capacity. **Note: If you are a member of the Patreon and have already secured early access via the form you do NOT need to RSVP on Meetup.** By popular demand and with the amazing friendship of the Highbinder Bar, we are introducing the **Charcuterie Board!** These are meaty games for experienced tabletop players or players who are comfortable with complexity. **About the Games** This series will focus on bringing experienced tabletop fans and meaty games together. These games will include titles with rulesets that are a bit more complex, take a bit more time, and are often strategic and competitive. DCGG will curate the games and provide trained game hosts to help get games going quickly and make sure all players are supported as they learn and engage with the games. The month's games will be in the title of this event. **Who this event is for:** Self-declared board game enthusiasts and/or people people looking to get into the hobby of tabletop games. While our game hosts will be there to help explain the game and rules, this event is targeted at players who are comfortable learning lots of rules and dedicating a few hours to a single game. And as always, DCGG enforces polite and healthy play spaces. **Not into complex games or just not ready for the meaty games?** Please explore our other events, such as Meat You at Fat Pete's or Rhythm and Brews, which have more party-focused and easy- to mid-level games. **What if we don't have enough players?** Through the power of teamwork and friendship, we will find a way for everyone to play and have a good time. **Please arrive on time, or else your space will be forfeit (cuz we often cant wait for people to get games going).** **BUT WAIT THERES MORE:** If you are interested in becoming a Supporting Member and enjoying perks like: * **Early RSVP Access:** Supporting Members will get early access to RSVPing to regular events. * **Town Hall meeting:** Supporting Members will be invited to participate in town halls and polls that will help determine how revenue past operating costs is directed. * **Discounted Ticket:** In the event that DCGG hosts paid ticketed events in the future, Supporting Members will be offered discounted prices. * The knowledge that you make all this possible!

[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“Venezuela’s Future—and Ours,”** an analysis of how the Trump administration’s intervention in Venezuela will affect that nation, the U.S., and the rest of the world, with Ernesto Castañeda, Director of the Center for Latin American and Latino Studies and the Immigration Lab at American University. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://www.ticketleap.events/tickets/profsandpints/dc-venezuela-future](https://www.ticketleap.events/tickets/profsandpints/dc-venezuela-future) .] On January 3rd, after a long military buildup, the United States used special forces to seize Venezuelan President Nicolas Maduro and his wife, Cilia Flores, from their residence in Caracas, Venezuela to stand trial here on criminal charges. The development marked a major turning point in our relationship with Venezuela and the rest of Latin America and raised a host of complex questions, not just for Venezuelans living inside and outside that country but for American citizens and other nations of the world. Coming to the stage to break down what all of this means is Ernesto Castañeda, a scholar of Latin America who has given several excellent Profs and Pints talks on immigration policy and has given dozens of interviews to media outlets around the world in the wake of the U.S. raid. In a talk offering informed perspective on the latest news developments, Professor Castañeda will discuss various theories about why the U.S. conducted the operation to get Maduro out of Venezuela. He’s put our nation’s current plans for Venezuela into context by touching on previous U.S. military interventions in Latin America and beyond. Professor Castañeda will look at the implications of recent events for U.S. politics and U.S. citizens and what such developments tell us about the balance of power in the United States. He’ll examine the distance between decisions made by the White House and public priorities, touching on how it all relates to our immigration policies and our views about peaceful protest and democracy. He’ll consider how the Venezuela raid and our actions since have altered relations between the U.S. and other nations and provide scenarios about what the future might hold.

• If you RSVP for an event, please attend that event or cancel at least two hours before the event starts. Members that no-show will receive one warning then will be benched (suspended) from events for two weeks. Three no-shows can result in a permanent ban. (No-shows create uneven numbers and prevent folks on the waitlist from playing. Please do your part to un-RSVP as soon as you know that you cannot attend an event.)
• Members must have a way to communicate with organizers and hosts. This can be through the Meetup app messages or by providing other contact info.
• Any member can ask a host or organizer to have their skill rated for event attendance purposes. You will not be allowed to participate in events higher than your NTRP rating. (We may try to limit numbers or have multiple events on a given day to accommodate players of different skill levels and also to help alleviate the court availability problem).
• All members shall conduct good sportsmanship and be courteous to other members at all times.
• Sexual harassment, racism, sexism or any kind of intolerance will not be tolerated and will result in the permanent ban from the group.
• If member receives three warning infractions, the member will be suspended from the Meetup for a period of one month. If a member is suspended twice (six warnings), that member will be permanently banned and any membership dues will then be forfeited.
• If you are scheduling to play with others outside of a MoCo Topspinners event, and you know that there is a MoCo Topspinners event scheduled for that day at that time, please try to use courts other than the courts where the event is scheduled, or move your time so that it does not conflict with the Topspinners event.
For a list of complete rules and definitions you can see the MoCo Topspinners front page. If you have questions, don’t hesitate to contact us. We are hoping for a fun season but we may have to wait for courts and leave earlier than we are used to. Please be patient as we adjust to this new normal and try a few different things that will hopefully help the situation. Happy playing!

**Bring a flash light.** Some of the walk is lit with street lights. Some is not. **YOU WILL NEED SPIKES. TRAIL IS ALL ICY !!!!** We will be hiking along the historic Alexandria waterfront down and through scenic Old Town to the Wilson bridge and back. Lovely views of the river, as well as of Old Town. Part of the walk is on the Mount Vernon Trail bike path. Hike is mostly flat, and on paved surfaces or board walk. Please note the hike leaves at 600PM sharp. There are bathrooms at the halfway point. **Meet at the small parking area closest to the bike path. First left on Marina Drive. Not the large marina parking area that is further along.** We walk pretty briskly around 3.4-3.8 miles an hour. I assume if you can’t keep up, you can always find your way back to the starting point. Hope you can join our group of stalwart regulars and cheery newcomers. Happy hiking. Most of the walk has street lights, but not all so, but bring a light.

We’re excited to bring the community together for an evening of learning and connection. This time, we'll have a community member sharing a use case and, as usual, an Elastic employee sharing their expertise as well. Come support your fellow developers, learn something new, and meet others who are passionate about search, observability, and security. **Date and Time:** Tuesday, February, 10th from 5:30-7:30 pm EDT **Location:** Elastic Arlington Office - 4100 Fairfax Drive, Ste 500, Arlington, VA 22203 **Agenda:** * 5:30 pm: Doors open; say hi, grab a seat, and eat some food. * 6:00 pm: "Streaming Context: Powering Semantic Search with Kafka and Elasticsearch", by Sandon Jacobs, Developer Advocate at Confluent * 6:30 pm: Q&A * 6:40 pm: "Agent Builder: Providing Relevant Context for Data Driven Agents", by Joe Gentsch, Senior Solutions Architect at Elastic * 7:10 pm: Q&A * 7:20-7:30 pm: Networking & refreshments **Talk Abstracts:** **"Streaming Context: Powering Semantic Search with Kafka and Elasticsearch"** As the de facto platform for event streaming, we’ve seen how data from Apache Kafka can easily empower basic keyword search. But let's be real, modern semantic search applications need *context* to interpret the real meaning and intent of a user's query. We could wait around for the next batch job to kick off and provide that context... *or* we could serve it up in near real-time right from our data streams. In this talk, we'll discuss how to leverage data streams from Kafka to power much smarter semantic search with Elasticsearch. We’ll follow a simple event from a Kafka topic and see how it transforms into a powerful vector embedding. Then, we’ll see this whole flow in action using a k-Nearest Neighbor search to instantly find similar items in milliseconds. While my code examples will be in Java or Kotlin using the Spring Boot and Spring AI ecosystem, FEAR NOT! The core concepts—getting data into a vector format via a stream—are totally language agnostic. Join us to grab a few practical ideas you can take and use in your next project! **"Agent Builder: Providing Relevant Context for Data Driven Agents"** What are agents? What is context engineering? Join us as we dive into the importance of context engineering for providing relevant information to agents, and how to build grounded agents using Elastic Agent Builder. **Parking:** * The building’s parking garage is operated by Colonial Parking and is located off N.

Montgomery County MD Real Estate Investors, Agents and Professionals! We just launched a Cash-Flow Breakfast Club for your area! This is the most unique real estate investor club, education, networking and mastermind event in the US! **Join us for our official launch event for Montgomery County MD on February 26.** **This is a 12 part education series with new topics every month. This event is session 10 of 12!** **This event is free but has very limited seating and we are limited to the first 50 to RSVP! Join us and become a founding member of this amazing community!** *(it is ok to attend even if you missed previous sessions. Each session has stand alone topics. You can also attend other near by locations to get caught up on sessions that you have missed.)* **Very limited seating. In-person only.** **Make sure to RSVP today to reserve your spot.** **When: February 26, 2026 @ 5:30pm - 8:30pm EST** **Where: Twinbrook Library** **202 Meadow Hall Dr, Rockville, MD 20851** The Cash-Flow Breakfast Club is NOT just a meet up. It’s the most unique Real Estate Investor Community of Mentors, Coaches & Masterminds. A community of growth oriented, abundance mindset, go-giver individuals with a BARE MINIMUM commitment to become financially free through real estate investing. We focus on providing education and building networks to help every member solve their cash-flow freedom equation, so they can have the time-freedom needed to follow their passions, make a lasting impact and even change the world! The unique format of this event, which consists of high-level education, gamified networking, mastermind breakout sessions, case studies, group deal analysis, market deep dives, and peer-to-peer coaching facilitation makes this the most impactful local real estate investor group a real estate investor can be a part of. The foundation of the group is built around the belief that everyone in the room has the potential to change the world… however most of us never have the time, energy or financial situation to even dare to dream big enough. Most of us have passions that will never be followed, amazing businesses or ideas that will never be pursued… unless we can solve the Cash-Flow Freedom Equation, which ultimately leads to Time-Freedom. Once that happens it is usually much easier for us to think bigger, dream bigger, be bigger. · 🤯 Learn more about the Cash-Flow Breakfast Club [HERE](https://cashflowbreakfastclub.com/) · 🥇 Get in the VIP List to be notified about the next event in your area [HERE](https://the.cashflowbreakfastclub.com/VIP) · 🤙🏼 Learn more about Launching your own Cash-Flow Breakfast Club Location [HERE](https://cashflowbreakfastclub.com/launch-your-own-club/) · 🤝🏼 Learn more about becoming an Affiliate-Sponsor at one of our club locations [HERE](https://cashflowbreakfastclub.com/affiliate-sponsors/) · 📷 View photos and videos of some of our recent events [HERE](https://cashflowbreakfastclub.com/about-the-cash-flow-breakfast-club/) · 😎 Looking to represent?

Join our weekly walking meetup to have fun, maintain a healthy lifestyle, meet new people, and enjoy the weather! We meet Saturdays at 10am, halfway between the Reston *Container Store* and *Not Your Average Joes* (by the metal benches), leaving no later than 10:05. Every week, rain or shine, we start by walking along the Green Trail to reach Lake Anne Community Center. Once there, we pause for water/bio (often staying a few minutes extra from April-November, due to the local Farmer's Market), and then we circle Lake Anne and head back to our starting point. It's roughly 3-4 miles and takes about an hour and a half. Afterwards, some members will often head to *Not Your Average Joes* or another local restaurant for a quick drink/meal before tackling the day. This event is open to all ages and fitness levels. Dogs are welcome, and we recommend dressing for the weather (umbrella, water, snow shoes, hat, etc.) since we'll walk rain or shine. Also, feel free to bring a friend! By signing up, you accept and assume all risks and responsibilities with this activity, and nobody will be held liable.

Join us for a cozy, in-person journaling session! Whether you’re new to journaling or a seasoned writer, this meetup is a great opportunity to carve out some intentional time for self-reflection, creativity, and connection with others. Event Outline: • We’ll begin with brief introductions so everyone can get to know each other. • I’ll provide a journaling prompt to help guide your writing. • Afterward, we’ll take about 10 minutes to write quietly. You can use the prompts or go wherever your thoughts take you! • Once we’re finished, we’ll come back together and share (if you feel comfortable). This is a chance to reflect on the process or share insights, but sharing is completely optional. • We'll repeat this process with another prompt or two as time allows. Bring your favorite journal or notebook, and get ready to enjoy some thoughtful, reflective time in a welcoming community. Grab a coffee or tea from the café, settle in, and let’s journal together! Feel free to come as you are—no prior experience necessary. We can’t wait to meet you!
