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.

**🐍 🛢️ How To Sell Snake Oil (& Your Best Ideas)** Persuasive Speech Patterns with Dr. Ed Tori ***‼️In person at room 401-D at the Martin Luther King Jr. Memorial Library, 901 G St NW, Washington, DC*** **How do you get your ideas to land?** Have you ever heard phrases like “there’s no buy-in,” “they’re resistant,” or “this group will not move.” But what if resistance is not the problem? What if the issue is the way we communicate? In this lively, participatory workshop, **Dr. Ed Tori** will introduce you to a set of practical and surprisingly playful **persuasive speech patterns** drawn from his work in influence, hypnosis, storytelling, and behavior change. You will learn how people naturally shift into more persuasive communication when pressure is removed and creativity is sparked. At the center of the experience is a hilarious improvisational game inspired by the card game Snake Oil. Participants take on imaginative roles like zombies, pirates, or kindergarteners. Others must invent and pitch made-up products on the spot. The role-play creates immediate psychological safety and unlocks natural persuasive instincts you may not realize you have. Ed uses these moments to teach simple, powerful patterns you can apply to real conversations. **What you will explore** * Why people communicate more confidently and creatively when the stakes feel low * How persuasive speech patterns can transform conversations in facilitation, coaching, leadership, and team settings * Why resistance is often a signal of mismatched framing rather than unwillingness * How to speak to the human behind the role, label, or stereotype * How playful practice builds shared language, humor, and camaraderie among intact teams * How these patterns apply across contexts: healthcare, corporate environments, education, and family systems **What you will experience** * A fast-paced, interactive group exercise that helps you practice persuasive communication through play * Step-by-step teaching of speech patterns you can start using immediately * Opportunities to experiment, reflect, and compare approaches * Practical tools you can adapt for your own clients, teams, or classrooms **Who this is for** * Anyone who works with groups and wants their ideas to be heard. * Ideal for facilitators, coaches, consultants, organizational development practitioners, educators, designers, and leaders at any level. This session is especially helpful for people who work in environments where “resistance,” “lack of buy-in,” and “difficult stakeholders” are common refrains. **About the presenter** * Dr. Ed Tori is a physician, educator, and expert in influence and communication whose work blends behavioral science, improvisation, and hypnotic language patterns. He teaches leaders, clinicians, and teams how to help others think, feel, and act differently through ethical persuasion and intentional communication. His sessions are energetic, funny, experiential, and unforgettable. * NOVA Scribes has entered into a partnership with the IFVP: the International Forum of Visual Practitioners! This workshop is an IFVP Learning Lab. All IFVP members have access to Learning Labs at https://ifvpforum.circle.so/c/learning-hub/ This workshop will be recorded and posted on YouTube for anyone who cannot attend.
