[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.

### **What’s Unhappy Hour Breathwork, you ask? It’s our conscious breathing session to embrace our discomfort, sip some soothing tea, and dive deep into the beautiful chaos that is our childhood trauma, daddy issues, mommy issues, work stress, and those oh-so-fun failed relationships. Think of it as a cozy gathering where we can unpack our baggage together, all while sharing a laugh or two (or maybe a few tears).** Let’s be real life isn’t always sunshine and rainbows, and that’s perfectly okay.**We will give ourselves permission to be gloriously miserable for a full 90 minutes to** release the weight of our struggles. By using our own conscious breathing we’ll transform our experiences into something powerful and healing. Session will end with a soothing sound bath. Tea will be provided! Mark your calendars for this weekly dose of camaraderie and self-discovery. **What is Breathwork?** Breathwork falls under an umbrella term with many different marketing names and techniques. For this session we will be focusing in one technique while laying down on our back. This is NOT your typical relaxing breathing and it DOES NOT INVOLVE ANY YOGA movement. Breathwork takes us deep into the subconscious mind to make necessary changes and improve our lives by releasing emotional baggage and healing emotional wounds. When we tap into deep states of consciousness emotional release may take the shape of crying, laughing, even screaming. Many people like to call it years of therapy in one single session. It is very common to experience moments of clarity, bliss and many Aha moments during this session. Each person will experience something different with every session. All you need is an open mind and your own breathing to achieve results with no prior experience. Please note breathwork cautions before booking. **What you may experience during this session:** -Deep healing of emotional wounds, grief and traumas -Ability to connect to your higher self, Ancestors and the divine -Release anxiety -Improve emotional balance -Increased feelings of joy, happiness, and inner peace -Ability to create self-love and improve relationships **What to bring:** -Your own water bottle -A pen and notebook -A Yoga mat (or use one at the studio) -A blanket ( or use one at the studio) -Eye mask (if you have one) -Comfortable clothes to breathe and lay down **About Jenny Perez Curandera:** Jenny is a Curandera Shamanic Healer born into the Curanderismo Tradition. Her core values are to LIVE IN HARMONY with great spirit, the elements, nature, animals and people. DO NO HARM TO OTHER PEOPLE, PLANTS OR ANIMALS.

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.

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. ━━━━━━━━━━━━━━━━━ **Investors move fast. Most agents don’t.** If you can’t evaluate a deal quickly and confidently, you lose credibility—and the opportunity disappears. Deal or Disaster teaches a simple, repeatable framework to determine in minutes whether a deal prints money or burns it. In this session, you’ll learn a 5-minute investment evaluation system that works across flips, rentals, BRRRRs, wholetails, and creative deals. The goal isn’t perfection—it’s speed, clarity, and credibility. We’ll break down: * How to identify the investor’s true goal before running numbers * A fast, reliable method to estimate ARV with confidence * How to calculate the real all-in acquisition cost * Simple heuristics to ballpark rehab and improvement costs * The key metrics that reveal whether a deal works—or should be killed You’ll also learn the most common red flags that signal bad deals, thin margins, and hidden risk, so you know when to pause or walk away. When you can analyze deals in minutes, you earn authority, build trust, and become indispensable to investors. Speed creates opportunity—and opportunity creates repeat business. If you want to move from real estate generalist to trusted investment strategist, this session gives you the framework to do it. ━━━━━━━━━━━━━━━━━ **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.
