Here's what to expect when you walk in: * A warm welcome and a name tag. You'll know somebody within five minutes. * Free voice coaching from me. Breath, tone, range, the stuff that makes you sound better fast. * We'll teach you the anthem in four-part harmony. You'll be standing next to a guy who's been doing this for years. He's got you. * We sing other songs too. The chorus has a full repertoire and you're welcome to stay for all of it. What to bring: * Yourself * A water bottle * An open mind and a sense of humor That's it. No music to buy, no audition to pass, no commitment beyond showing up. Location: St. Paul's Lutheran Church, 4900 Connecticut Ave NW, Washington DC. Free parking. Walk-in friendly. Questions? Send a message through Meetup.

While we do aim to play seriously and challenge ourselves, the focus is more on growth and enjoyment than simply winning at all costs. That’s why the title doesn’t include “competitive” or “social”—we want a healthy mix of both. We do expect a mindset geared toward learning and getting better over time. That said, this event isn’t intended for total beginners; an understanding of the game is expected so that everyone can contribute to meaningful and engaging matches. The host holds the right to remove you from the game if they believe that you are at a C level (absolute beginner). If you can't pass to the setter, for example, you are a beginner. **Skill Level:** 1. **If you want to know your level, please see the link below:** [Smiley Social Volleyball Levels](https://docs.google.com/document/d/1PojSi4qdlRsv1msCHhvpQ43iDc4FfzQwpWCc3kafVMY/edit) **YouTube:** The games may be recorded and uploaded to our channel here: Let the host know if you have an issue with this.

We’re excited to bring the community together for an evening of learning and connection. This time, we'll have a community member from Chainguard 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, May 19th, 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: The SBOM Pile in Your S3 Bucket: Turning Bills of Materials Into a Risk Dashboard; and Watching It Shrink with Chainguard, by Mike Barreta, Senior Manager, Engineering at Chainguard * 6:30 pm: Q&A * 6:40 pm: **Agentic Observability: Next-Gen Alerting and Auto-Detected Significant Events**, by Jason Rhodes, Senior Manager, Software Engineering at Elastic * 7:10 pm: Q&A * 7:20-7:30 pm: Networking & refreshments **Talk Abstracts:** **"The SBOM Pile in Your S3 Bucket: Turning Bills of Materials Into a Risk Dashboard; and Watching It Shrink with Chainguard**" Most organizations now generate SBOMs because someone — EO 14028, a FedRAMP auditor, an ISSM — told them to. They land in an S3 bucket, get versioned, and are almost universally never queried. This talk is about what happens when you finally do. I'll stand up a self-contained Elastic stack, pour in SBOMs (SPDX), SLSA provenance, Sigstore signatures, Grype vulnerability scans, the CISA KEV catalog, and OpenVEX adjudication for 30 container images, and show the queries that only become possible once SBOMs stop being compliance artifacts and start being telemetry: which packages I actually run right now, which CVEs are real exposures versus VEX-suppressed noise, what swapping a stock image for its Chainguard equivalent would buy me, and how much of my CVE list is just stuff I inherited from the base layer. Then the cleanup. The same dashboards on Chainguard images show what disappears when the SBOM is small, the signatures verify, and the advisory feed is active: \~9,000 fewer CVEs and \~2.5 GB saved across 20 image pairs, KEV exposure dropping from 7 hits to 0, compliance pass rate going from 0% to 76.5% against NIST 800-218 / FedRAMP Moderate / SSDF. **Bio:** Mike Barretta leads Chainguard’s public sector solutions engineering team, focused on helping ensure the federal government receives its fair share of the future. Barretta has worked across civilian, defense and intel programs in a variety of roles—software developer, data scientist, solution architect—for a variety of organizations—system integrators, consulting companies, software vendors—with the common purpose of creating and championing technologies and techniques for simplifying the extraction and utilization of information from lots of data. Having witnessed the ever-increasing threats to those systems, Barretta is now focused on methods and mitigations to secure them **Agentic Observability: Next-Gen Alerting and Auto-Detected Significant Events** We're rebuilding Elastic's alerting engine to make alerts more flexible\, more powerful\, and more valuable as data\. Next\-gen alerting rules will run anything ES\|QL supports and capture whatever fields matter to you\, so alerts carry the context you need for real downstream analysis\. And if you'd rather not manage these rules yourself\, AI agents can help\, drafting them from natural language\, recommending tuning and configuration changes\, and reducing noise through deduplication\. On top of this, we're also building a new Significant Events system which automatically builds a continuously updated knowledge base of your incoming data's own metadata. Using this deep understanding, our agentic tools will detect significant events from log patterns, anomalies, and predicted behavior — without you having to create a single rule. **Bio:** Jason Rhodes is a software engineering lead at Elastic, where he works on alerting and observability features. Based in the DC area, he has over 15 years of experience in software development and has been an active contributor to the local tech community — creating and organizing Baltimore NodeSchool and charmCityJS. When he's not writing and reviewing code, he's probably watching too many movies. **Parking:** * The building’s parking garage is operated by Colonial Parking and is located off N.

Join us for the world premiere of the musical ***Aguardiente: Where Magic Transcends Borders,*** commissioned by GALA and conceived by Helen Hayes multi-award winner Luis Salgado from Puerto Rico and Colombian artist Daniel Alejandro Gutiérrez. Blending Afro-Caribbean rhythms such as bomba, currulao, and cumbia, and Gabriel García Márquez’s magical realism, Aguardiente is a bold new musical about the messy, urgent act of making art in a world on fire. As a group of artists race to finish a new show, their rehearsal room becomes a battleground of ideas, ambition, and lived experience—especially for a composer whose undocumented status makes the dream of success anything but simple. As the team wrestles with what story they should tell, the line between reality and imagination begins to blur, until—like two currents meeting in the same river—the artists’ own struggles spill into the story they are creating: a vibrant tale set in a river town on the brink of environmental collapse, where two young lovers must decide whether to stay and fight for their homeland or leave in pursuit of a dream, making Aguardiente a theatrical journey about migration, memory, and the complicated act of transforming real lives into art. **PERFORMANCES:** ***Aguardiente*** is a bilingual production with surtitles in English and Spanish, and runs April 30 through May 24, 2026. Performances are Thursdays through Saturdays at 8 pm and Sundays at 2 pm. The show is approximately 160 minutes long and includes one intermission. Community Night is Thursday, April 30.

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!
