[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.

📚 Do you love reading, but wish you had a structure and a community to share your insights with? Join our small circle of curious minds (just 4 members per gathering) as we come together for an hour of focused reading—in the calm setting of a library or the cozy atmosphere of a café. Here’s how it works: First part: Quiet reading on your own—bring a book you’re exploring, whether it’s philosophy, history, psychology, literature, or anything meaningful to you. Second part: We regroup and each person shares key takeaways, insights, or questions sparked by their reading. This sparks a structured yet free-flowing conversation around ideas, perspectives, and personal reflections. Why join? Add structure to your reading habit. Discover new books, authors, and ideas through others’ choices. Build real connections by sharing and listening deeply. Socialize around something meaningful instead of small talk.

We are told to "go with the flow," but life is full of grit. **Question 1:** Is suffering an inherent part of the "Earth curriculum," or is it purely a mistake of the human mind’s perspective? **Question 2:** Where is the line between "accepting what is" and being passive/lazy? Can you take radical action to change the world while still being in a state of nondual acceptance? **Question 3:** Think of a current "suffering" in your life. If you removed the story you tell yourself about it, what is actually left? *Thank you guest facilitator, Erin!* \-\-\-\- ***“I am struck with how rare it is to find a few good friends on the path. It is easy to find people who simply want to sit and be entertained by teachers, or who want to sit and entertain by playing the role of teacher. In other words, the quest for affirmation often outweighs the quest for truth.*** ***Yet you may have one or two good friends, and definitely have one or two waiting to be discovered. Find them; be thankful.”*** ***— Shawn Nevins*** 'What will make me happy in life?' ... 'Am I my thoughts?' ... 'What is Enlightenment?' ... We meet every week to ask questions like these in the pursuit of Self-Knowledge and Truth. We are interested in topics like: Zen, stoicism, spirituality, psychology, mindfulness, Nisargadatta, non-violent communication, Socrates, existential philosophy, Alan Watts, taoism, Eckhart Tolle, meditation, Ramana Maharshi, etc. But we are not affiliated with any dogma, philosophy, or religion. Our goal each meeting is to serve as mirrors for one another using question-based inquiry in a safe environment. In a session, every participant takes turns discussing the week's question or topic, and the group asks reflective questions without any agenda besides trying to understand the person's beliefs. A few other guiding principles of our group: * No one is obligated to share * Be honest with yourself and others * Do not try to convince others to believe or think as you do * Keep the focus on the person being questioned We meet at the [Bethesda Library](https://maps.app.goo.gl/GWMozF8zpY1m1PY26) every Monday. The library is a 5 minute walk from the Bethesda Metro on the Red Line, approx 25 minute Metro ride from Metro Center and Gallery Place stations. The library has a a parking lot with metered parking for $1/hour. \*\*\* WE WILL BE IN MEETING ROOM 3 UNLESS OTHERWISE NOTED ----- THE MEETING ROOM IS IN THE BACK OF THE LIBRARY \*\*\* Please contact us with any questions!

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.

It's supposed to warm up a little heading into the Valentine's Day weekend so it's perfect weather to weed a park. We are NPS Weed Warriors and Arlington Regional Master Naturalists and you should volunteer with us on Sunday, February 15 to learn about nature and remove invasive plants from everyone's favorite urban island. Meet us at the entrance to the bridge (on the parking lot side, look for the sign) at 10:00 and bring your garden gloves and loppers/pruners if you have them. If not, we can provide gloves and tools. Wear long sleeves and pants and don't forget a water bottle. We will have tasks ranging from easy (cutting English ivy and honeysuckle vines from trees) to hard (sawing down bush honeysuckle). Parking at TRI can be tight if it's a pretty day. When the parking lot is full, you can park in Rosslyn and take the trail down. If you can bike or walk or take public transit, that's wonderful. We'll see you there! Erica, Stephanie, and Heidi P.S. If you can't wait until then to RIP (Remove Invasive Plants!), go here to find more volunteer opportunities in Arlington parks: [Volunteer to Restore Native Habitat – Arlington Regional Master Naturalists (armn.org)](https://armn.org/volunteer-opportunities/)

### 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.

Let's grab some coffee/food and share a morning chat! The East Market has an ample parking lot and outdoor and indoor seating. Grab a cup of coffee from Winston's Coffee & Waffles or on your way to East Market and meet us on the second floor - table behind or east of the elevator. If the weather cooperates we will be meeting in the patio. Per what this group is about: "Everyone is welcome! International transplants to Columbus who want to improve language skills, Columbus residents who want to discuss international travel and culture, and anyone who enjoys getting together for good conversations."

**People Analytics 101: Making Sense of Compensation Data** Compensation data is one of the most widely used and widely misunderstood forms of people analytics. The session will cover where compensation data comes from, including market pricing data, internal payroll data, and benchmarking sources, and how companies think about structuring and analyzing that information. We will explore how compensation data is leveraged to set salary ranges, manage internal equity, support hiring and retention, and align pay with business strategy. A portion of the session will address common data challenges and limitations, such as market noise, inconsistent job matching, and incomplete datasets, while keeping the primary focus on practical use rather than technical depth. The session will also look ahead at where the space is going, including the growing impact of pay transparency laws, expanding pay equity requirements, and emerging regulations in the US and Europe that require organizations to report on gender and pay gaps. The goal is to give attendees a clear mental model for how compensation analytics works today and why getting it right is becoming increasingly critical. (note: we are back at Rev1 this month!) **About Our Speaker** [Alex Moore](https://www.linkedin.com/in/alexscottmoore/) is the founder of [Moore Cooperative](https://moorecooperative.com/), where he advises organizations on compensation strategy, pay equity, and people analytics. His work focuses on helping organizations like the Ohio Supreme Court design, analyze, and communicate compensation systems that are data-informed, defensible, and aligned with organizational goals. Alex lives in Granville, Ohio and has three little kiddos. More info at [cbusdaw.com](https://cbusdaw.com)
