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.

📚 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.

[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“Demography as Destiny,”** on understanding the links between population trends and world events, with John Rennie Short, geographer, professor emeritus of public policy at the University of Maryland, Baltimore County, and author of *Demography and the Making of the Modern World: Public Policies and Demographic Forces.* [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-demography-destiny](https://events.ticketleap.com/tickets/profsandpints/dc-demography-destiny) .] The size of a family doesn’t just affect food and clothing budgets and space needs. If it reflects a broader trend in birth rates, it also can have a profound impact on politics, the economy, and world affairs. Come to Washington D.C.’s Penn Social for a fascinating look at how demographic forces shape the modern world and have driven developments such as the Arab Spring, political unrest in Sri Lanka and Nepal, economic growth in Vietnam and India, the budget crisis in the United States, and the rise of nationalist populism in Europe. Dr. John Rennie Short, who has written several acclaimed books on world trends and gives excellent Profs and Pints talks focused on geopolitical affairs, will break down how various demographic changes can alter nations’ destinies. You’ll learn how baby booms can dampen economic growth, as has occurred in central Africa, and how a “youth bulge” caused by the aging of a baby boom provides tinder for social unrest, as happened in the United States of the 1960s and 1970s and is the case today in Nepal and Sri Lanka. We’ll look at the “demographic dividend” reaped when a youth bulge ages enough to become economically productive and the roles that such dividends played in periods of sustained economic growth in Japan, China, and, most recently, Vietnam. We’ll look at how the aging of a demographic bulge into retirement years can strain national budgets and strengthen the appeal of conservative or populist political movements. You’ll emerge from the talk better equipped to make sense of political and economic developments in the United States and elsewhere around the world. (Doors: $17, or $15 with a student ID. Listed time is for doors. The talk starts 30 minutes later.) Image by Canva.

🍻 [World Product Day](https://www.mindtheproduct.com/world-product-day/) is about more than product — it’s about the people who build them. Join **ProductTank DC** for a celebration bringing together product professionals to connect, reflect, and recharge around this year’s theme: **Resiliency**. Product people are no strangers to change. We adapt, learn, and keep building—together. This evening is an opportunity to step back, celebrate that resilience, and recognize the shared challenges and wins that define our craft. Expect thoughtful conversation, practical insights, and a chance to reconnect with the product community in person. Whether you’re an experienced product leader, a new PM, or simply curious about product management, this meetup is a space to learn, contribute, and celebrate the people doing the hard work of building what’s next. **Special thanks to our host:** Clyde's of Chevy Chase! *Please note: Attendees are responsible for their own food and drink purchases. Food and drinks will be available directly from the venue*

**ProductTank NoVA is back!** After a brief hiatus, we are relaunching the chapter with a format that cuts out the fluff and gets straight to the reality of building. Every product feed is flooded with AI hype right now, but what does it actually look like on the ground? Instead of a polished keynote, we are hosting **0 to 1 with AI: Real Product Talks**—a "Show & Tell" featuring 3–4 lightning talks focused on the intersection of AI and product. The framing for the talks is simple: *"Here is what I'm building, and here is what I'm stuck on."* We want to look at the messy, 0-to-1 reality of integrating AI into your workflows and products. *(Want to share what you are working on? Reach out! The bar is low-pressure, just 10–12 minutes to talk about a real AI problem you are trying to solve.)* **Agenda:** * **5:30 PM - 6:00 PM:** Doors open, networking, & name tags * **6:00 PM - 6:10 PM:** Welcome + Chapter Relaunch Intro * **6:10 PM - 7:30 PM:** Lightning Talks (Three 12-min talks + 5 mins Q&A each, with a 5-min stretch break) * **7:30 PM - 8:00 PM:** Open networking * **8:00 PM:** Soft close **Location & Logistics:** Herndon Fortnightly Library (Extended Hours Meeting Room) 768 Center St, Herndon, VA 20170 * **Parking:** We'll meet at the library, located just behind the Herndon Municipal Center. There is plenty of free public parking available around the municipal center. * **Metro & Bus:** Take the Silver Line to Herndon Metro Station, then connect via Fairfax Connector Route 921 or 950 to Historic Downtown Herndon. * **Driving (via VA-267/Dulles Toll Rd):** Take Exit 10 North (Centreville Rd, which becomes Elden St).

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!

This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them. Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance". Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you. The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life. Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.
