Machining

Hi everyone! Tuesday Night Skates are in full effect! Meet every Tuesday outside of the NOMA-Galladudet U Station at the North entrance (1305 2nd St NE). We will head out at 7pm sharp for an 8 mile skate followed by pizza! We'll skate up the Metropolitan Branch Trail to the Ft. Totten Metro station and back down the trail to M St NE for pizza at Andy's. See ya there! This skate is led by Asher and myself. 🛼 This ride is BEGINNER FRIENDLY! While the full ride is 8 miles long, you have the option to tap out at one of the three red line metro stations along the route in both directions. You'll also have an opportunity to learn new skills and practice drills with the skate leaders at our regroupping spots along the route. The tap out points are as follows: 2 miles: Rhode Island Ave Metro 2.5 miles: Brookland Metro 4 miles: Ft Totten Metro 6 miles: Brookland Metro (on the way back) 7 miles: Rhode Island Ave Metro (on the way back) 8 miles: Andy's Pizza This is a great way to test and build up your endurance while skating! At least one of the skate leaders will skate at your pace, so you'll never be left behind. Join us at Andy's Pizza afterwards for a FREE slice of pizza with the purchase of any alcoholic beverage or N/A lemonade! Route Map: https://www.gmap-pedometer.com/?r=7752153 If we need to cancel one week due to weather or other reasons, we'll update the event page in advance.

We will have open shop hours for anyone to bring their bikes to work on or need help fixing your own bike. We will also have bikes that need to be fixed so you can learn if you like. We will need everyone to sign in when arriving and sign out when leaving so we can keep track of volunteer hours and shop times. Suggested donation of $15 per hour for use of tools and space would be appreciated. Thank you!

For the first half hour of class, beginners will learn 5 organ & spirit enlivening qigong exercises. After a brief meditative walk, beginners will learn the first of six section of Lao (old) Yang tai chi chuan as taught by Teacher Lu Hung Bin. Remember to wear comfortable loose-fitting clothing & flat comfortable shoes. For more information, call 301-466-5894 or email: info@dancinginsilence.com

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. Randolph Street * Book a spot on[ SpotHero](https://spothero.com/search?kind=address&latitude=38.8818514&longitude=-77.1095268&search_string=4100+Fairfax+Dr+%23500%2C+Arlington%2C+VA+22203%2C+USA) * A Metro Station is located across the street

This is an opportunity for volunteers to support a professional mechanic as he guides customers working on their own bikes. If you know how to do some basic repairs, that's a plus, but even if you don't, you can greet customers and manage who gets helped next. Feel free to attend for only a portion of the time if you can't be there the whole three hours. Please note that this event is not usually an opportunity to learn about bicycle repair, since the mechanic tends to be very busy helping customers, especially during the warmer months. But it's a great way to contribute to Velocity, since almost all the funding for the volunteer program comes from the work done at the shops.

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!
