In times like these, we can see more clearly the potential for humanity when it works together in unison – as well as the challenges if we don’t and continue to operate as we have been before. If you could design the world of the future, what spiritual values would you want to see in it to help realize those potentialities? All of us hope for a better future for ourselves and for our children, but how do we get there? What sort of ideas and behaviors will we need to leave behind – and what values will we need to build the foundation of the future on? And how can we work together to build a future that works for all of us, where each of our fullest potentials as human beings can be realized? Come join a different kind of conversation – one that welcomes every perspective in a search for the truths that unite us all – as we discuss the spiritual perspective offered by the Bahá’í Teachings on what a future society might look like and the role each of us can play in creating it. Join us for a lively discussion as we explore the role of spirituality in the unification, peace, and progress of all. *“The betterment of the world can be accomplished through pure and goodly deeds, through commendable and seemly conduct.*” – Bahá’í Teachings \*\*\* This event is free and open to all regardless of background or belief. Donations will not be accepted.

**In response to inclement weather this talk has been rescheduled for March 1st, with tickets for that date available at** [https://www.ticketleap.events/tickets/profsandpints/nv-satanic-panics2 ](https://www.ticketleap.events/tickets/profsandpints/nv-satanic-panics2). **Anyone who purchased tickets to attend this talk on January 25th will be getting a refund in the next week to ten days.** [Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“Satanic Panics,”** a look at waves of fear of demonic activity as an American tradition, with Luxx Mishou, cultural historian and former instructor at the U.S. Naval Academy and area community colleges. The 1980s found the United States gripped by fear of Satanic cults targeting children. They were believed to be corrupting young ones in daycare centers and tempting teens through subliminal messages on heavy metal albums or through the quiet inclusion of demonic rituals in role-playing games. Satanic serial killers supposedly stalked the suburbs. Doctors helped patients uncover what were claimed to be repressed memories of ritualistic satanic abuse. Parents, police, and politicians were urged to protect impressionable youths from both moral and physical danger. With Satanic cults deemed to be a real and material threat, it was a frightening time for everyone, including those who suddenly came under suspicion for doing evil deeds. Then, suddenly, it all faded from public consciousness, just as surely as did eighties fads such mullet haircuts, leg warmers, and Cabbage Patch Kids. Why did it all start? Why did it stop? And has this happened before or since? Hear such questions tackled by Luxx Mishou, a cultural historian and media specialist who has long researched the devious and villainous in cultural artifacts. She’ll discuss moral panics as a longstanding cultural tradition, with each new one stemming from fear of cultural shifts and shaped by the time and place where it occurred. Among the panics we’ll look into are the Red Scare of the 1950s and the public response to the gruesome 1969 murders committed by the Manson Family. Delving into the 1980s panic, Mishou will describe how it began with the 1980 publication of psychiatrist Lawrence Pazder’s memoir *Michelle Remembers*, detailing the suppressed memories of ritualistic abuse reportedly suffered by a patient. As that book quickly became a best seller, its ideas saturated American culture. A California daycare center became the focus of a three-year investigation, followed by three years of trials, based on allegations that its owner had engaged in secret ritualistic abuse of the children in its care. Mishou will lead you through the media that convinced the public that devil worshipers were among them, and she’ll talk about how reactions to imagined threats can have very real social costs.

**Agenda :** * 4.30 to 4.45 PM ET: Food and Networking * 4.45 to 5.30 PM ET: "Practical Applications of Model Context Protocol (MCP) (Feb 2026 Edition)" Hello Everyone! Please join us for our Feb 10th edition of the AI-ML MeetUp. **Please note this is an in-person meeting and light refreshments/food will be provided.** **Title:** Practical Applications of Model Context Protocol (MCP) (Feb 2026 Edition) **Description:** This session explores how the Model Context Protocol (MCP) can be used to connect AI models with real-world tools and data. Attendees will learn practical patterns for implementing MCP in production workflows and applications. Through examples and use cases, the session highlights how MCP enables more capable, context-aware AI systems. **Location:** The meeting will be hosted in the Applied Information Sciences ( AIS ) office in Reston, at 11440 Commerce Park Dr # 600 · Reston, VA. The location is also right off the Silver Line metro's Wiehle-Reston Metro Station. **Parking:** Parking is paid and can be validated at the AIS office reception. We will meet in Room Lake Anne. We hope to see you all there!!!!

IMPORTANT PLEASE RSVP @ https://www.meetup.com/washington-dc-elastic-fantastics/events/312487028/?eventOrigin=group_upcoming_events \*\*\* **Agenda:** * 5:30 pm: Doors open; say hi, grab a seat, and eat some food. * 6:00 pm: Talk 1 * 6:30 pm: Q&A * 6:40 pm: Talk 2 * 7:10 pm: Q&A * 7:20-7:30 pm: Networking & refreshments **Sandon Jacobs, Sr. Developer Advocate** ***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!

Join us for another session of our study group as we cover the book Domain-Specific Small Language Models. In this session, we will cover Chapter 1 Large Language Models and maybe even start Chapter 2 Tuning for a Specific Domain. This isn't just a lecture! Come ready to ask questions, share insights, and code along. Whether you're a beginner or have some experience, this is the perfect opportunity to continue to learn together. If you plan to work with the code on your own laptop during the session, try and download the code from here https://github.com/virtualramblas/Domain-Specific-Small-Language-Models/ ahead of time. We will be meeting at the North County Governmental Center this time that is across from the Reston public library.

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.
