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.

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!

[https://ridewithgps.com/routes/34803272 ](https://ridewithgps.com/routes/34803272) This trail is 22 miles long. Toilets are at the beginning, end, and near the middle of the route. There are plenty of opportunities to find a restroom elsewhere along the route. **PDF with points of interest and more details** https://ebikelovers.com/2021/01/23/trail-2-virginia-and-maryland-e-biking-from-washington-sailing-marina-to-national-harbor-fort-foote-and-old-town-alexandria-waterfront/ This trail is 22 miles in flat terrain with a fantastic view from the Woodrow Wilson Bridge and a lovely picnic area at the Potomac River. We arrive at 10:00 AM and leave at 10:15 AM. The meeting place is at the parking lot on the left near the public restrooms of the marina. The group stops a few times for slower riders to catch up. The distance will be 22 miles or shorter any time you are fully satisfied with biking for the day. Our bikes will always be in our sight. No additional locks are required to keep your bike safe on this trip. As usual, non-assisted bikers are most welcome. **About Jones Point Lighthouse** The lighthouse is one of the last riverine lighthouses in the country and the only one still standing in the Chesapeake Bay area. It was first lit on May 3, 1856 by keeper George L. Deeton. Today it is the focal point of Jones Point Park and a clue to area's history as a busy commercial center and naval base. Whale oil lamps were originally used to power the beacon at Jones Point, but in 1858 the Lighthouse Board allowed an Alexandria gas company to extend lines to the station. The land included one of the original District of Columbia boundary stones, which was installed by George Washington and marked the southern point of the ten-mile-square district. The stone is still visible today in the seawall just south of the lighthouse, and to the north of the lighthouse a marker designating the boundary between Maryland-Virginia can be seen. **About Fort Foote** Fort Foote was constructed in 1863 atop Rozier's Bluff to strengthen the ring of fortifications that encircled Washington, D.C. Two of the Guns that protected Washington are still there along with the remains of the fort's earthworks. **About the Woodrow Wilson Memorial Bridge** Also known as the Woodrow Wilson Bridge or the Wilson Bridge, the bridge is a bascule bridge that spans the Potomac River between the city of Alexandria, Virginia, and Oxon Hill in Prince George's County, Maryland. The original bridge was one of only a handful of drawbridges in the U.S. Interstate Highway System. **About National Harbor** National Harbor is situated on the banks of the historic Potomac River, just minutes from the nation’s capital. Featuring 350 acres of waterfront resort space, National Harbor is a destination unlike any other. The harbor is home to 160 stores, 40 restaurants, the Capital Wheel, and the best sunsets in the area. **Free Ride With GPS for E-Bike Lovers** Membership of the Ride With GPS E-bike Lovers club is now free as www.ebikelovers.com is generating sufficient income from ads to cover the costs.

Have you ever wanted to ***really*** immerse yourself in Pocahontas County, West Virginia? Here is your chance! Last Memorial Day Weekend, DC UL hiked a section of the Allegheny Trail (“ALT”) from Blackwater Falls to Durbin. Let’s knock out the next section this year: Durbin to Sherwood Lake. This section of the trail bisects most of Pocahontas County. Expect wet feet, regular ascents and descents, 4k feet of *daily* elevation change over 4 days, big miles, and very remote hiking. You must be in solid “Veteran Member” status for this one. In addition to this being a physically tough trek, it is at times tough to follow navigationally. The reward? When co-workers talk about Pocahontas around the water cooler, you’ll be able to say confidently, “***do I know*** Pocahontas County!" This section looks much harder than the one we hiked last year—hopefully, it will be just as funny. [Here is the trip report from that adventure](https://dculbackpacking.com/2025/05/29/trip-report-this-trail-has-everything-allegheny-trail-section-2-blackwater-falls-sp-to-durbin-west-virginia-may-22-26-2025-73-miles/): https://dculbackpacking.com/2025/05/29/trip-report-this-trail-has-everything-allegheny-trail-section-2-blackwater-falls-sp-to-durbin-west-virginia-may-22-26-2025-73-miles/ (For those of you who missed out on the Blackwater-Durbin section, and who want to someday hike the entire ALT, I’ll redo that section on a future trip). **The Plan** Friday: We’ll carpool at 3:00 p.m. from the Vienna Metro to Trainer, WV to leave a car or two. Then, we’ll drive to Durbin, WV to camp at a campground in town. Saturday, Sunday, Monday, Tuesday: We’ll hike SB on the ALT with tentative splits of 20, 19, 14, 16 miles. There may be a restaurant opportunity in Cass for Saturday evening. We pass a gas station convenience store on Monday, but it may be closed on Memorial Day. On Tuesday we may go for swim in Sherwood Lake before reversing the shuttle. We’ll have lunch at Station2 restaurant in Durbin before we drive home. **IMPORTANT: YOU NEED TO TAKE A HALF DAY LEAVE ON FRIDAY AND ALL DAY LEAVE ON TUESDAY (I’M ASSUMING YOU ALSO HAVE MEMORIAL DAY OFF).** I set the group size at 5 to make the shuttle work. I can expand it if we get enough drivers, so join the wait list if interested. I’m limiting this trip to Veteran Members. DC ULers have maps! [Everyone should use the FarOut app for this one](https://faroutguides.com/allegheny-trail-map/), with the maps downloaded. The trail is tough to follow and is often rerouted. FarOut is the most accurate line. https://faroutguides.com/allegheny-trail-map/ [Here is a Google Maps version](https://www.google.com/maps/d/viewer?mid=1VRr0rrSWM4sSTA5B_1bHqolLzLfcmzAZ&ll=37.84614715940329%2C-80.22346559843282&z=8): https://www.google.com/maps/d/viewer?mid=1VRr0rrSWM4sSTA5B_1bHqolLzLfcmzAZ&ll=37.84614715940329%2C-80.22346559843282&z=8 [You can buy maps to print here](https://www.hikethealleghenytrail.org/new-page): https://www.hikethealleghenytrail.org/new-page \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-**THE IMPORTANT WARNINGS**\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- I’m just a co-participant on this trip, not a guide or an expert.

**History** The history of [Blendon Woods Metro Park](https://www.metroparks.net/parks-and-trails/blendon-woods/) began long before its 1951 opening, rooted in a landscape of rugged ridges and deep ravines that made the land unsuitable for traditional farming. In 1945, a report proposing a metropolitan park system for Franklin County specifically highlighted these cliffs of Bedford Shale as some of the "wildest land in the vicinity". Following this recommendation, the recently formed park district purchased the first 229 acres in early 1949. Because the terrain was so uneven, developers had to cut a mile-and-a-half-long roadway through dense woods just to bring in heavy equipment. This initial preservation effort ensured that the mature second-growth hardwood forests remained largely untouched by the urban expansion spreading toward Westerville. Opening day arrived on Labor Day, September 3, 1951, marking Blendon Woods as the second park in the Columbus and Franklin County Metro Parks system. The final push to open was a frantic race; the State Highway Department only finished the primary gravel access road four days before the gates opened. Early staff members, consisting of just four full-time employees, had to hand-dig pit toilets and learn construction skills on the fly to build the first picnic shelters. Despite the dusty conditions and limited facilities, the park was an immediate success, drawing massive crowds from across Central Ohio. By the end of the 1950s, annual visitation had already climbed to over 190,000 people. As the surrounding suburbs grew in the 1960s, the park faced severe overcrowding that threatened its natural habitats. In response, Franklin County voters passed the first Metro Parks levy in 1960, providing the funds necessary for a decade of steady expansion. During this era, the park nearly doubled in size, growing from 264 acres to over 570 acres by 1968. Planners also addressed a critical water shortage by collaborating with the U.S. Soil and Conservation Service to build a lake in 1964. This body of water originally served as a temporary reservoir before its role shifted toward conservation and wildlife support. The 1970s marked a transition toward the specialized wildlife and educational focus for which the park is known today. In 1971, the Walden Waterfowl Refuge was established around the 11-acre Thoreau Lake, creating a sanctuary that remains restricted to provide a quiet habitat for migratory birds. A formal nature center was also developed during this period, expanding on the guided Sunday walks that had been a park staple since the early 1950s. The park’s famous "Monarch Mansion" also became a prominent fixture, starting a long tradition of raising and releasing thousands of monarch butterflies each September. These initiatives cemented the park’s reputation as a premier destination for birders and nature enthusiasts. In more recent decades, Blendon Woods has continued to modernize while maintaining its wilderness character. The 10-acre Natural Play Area was added in 2017, encouraging kids to explore the ravines and woods off-trail. This was followed by the opening of a $1.5 million inclusive playground in April 2025, designed to accommodate children of all physical abilities. The nature center also underwent major renovations to include immersive, three-dimensional exhibits and a new butterfly house. Today, the park encompasses 653 acres, preserving a unique geologic and biological corridor amidst the bustling Westerville and Northeast Columbus area. **Map of the Park** Here is a map of [Blendon Woods](https://www.metroparks.net/wp-content/uploads/2025/05/BLN_map_Inclusive-Playground-and-Butterfly-Trail_May-2025_1980px.png). **Summary** For this event, we will hike the Lake View, Hickory Ridge, Ripple Rock, Overlook, Brookside, and Sugarbush Trails. This sounds like a lot, but it will really be only a little over five miles. Blendon Woods has a few hills here and there, but it's not one of the more strenuous metro parks. **Where We'll Meet** We'll meet just in front of the Nature Center. This is about a mile into the park from the main entrance. You have to go past the Ranger Station and the Shadblow Reservable Area to get to it, so don't stop too early at the Ranger Station and get it confused with the Nature Center. **After the Hike** Afterward, we will head over to [Forbidden Root Restaurant & Brewery](https://forbiddenroot.com/restaurants/columbus-ohio/) at Easton for [drinks](https://forbiddenroot.com/restaurants/columbus-ohio/#dinner-menu) and [food](https://forbiddenroot.com/wp-content/uploads/Cbus-Food.pdf). We should be there by 5 if you can't make the hike and just want to join us for drinks. The brewery's actual address is [4080 Worth Ave, Columbus, OH 43219](https://www.google.com/maps/place/4080+Worth+Ave,+Columbus,+OH+43219/data=!4m2!3m1!1s0x88388a86d10b6619:0x4d42b470a5cf11d3?sa=X&ved=1t:242&ictx=111); however, I recommend pointing your GPS to the [Worth Garage](https://www.google.com/maps/place/Worth+Garage/@40.0542293,-82.9137962,17z/data=!3m1!4b1!4m6!3m5!1s0x88388b4df6082825:0x17582f0eccd9dda1!8m2!3d40.0542293!4d-82.9137962!16s%2Fg%2F11rzfvvv8b?entry=ttu&g_ep=EgoyMDI2MDQxNS4wIKXMDSoASAFQAw%3D%3D) across the street. Parking in this garage is free as long as you're not on the first floor, and it is literally right next to the brewery.

**History** The [Franklin Park Conservatory](https://www.fpconservatory.org/)’s roots trace back to 1852 when the Franklin County Agricultural Society purchased 88 acres of land to host the Ohio State Fair. After the fair moved to its permanent home, the city of Columbus transformed the grounds into Franklin Park in 1884. This transition shifted the space from a temporary event site to a dedicated public green space for the growing community. The park became a central hub for outdoor recreation and early civic gatherings in the neighborhood. In 1895, the landmark Victorian-style Palm House opened its doors, drawing heavy inspiration from the Glass Palace of the 1893 World’s Columbian Exposition in Chicago. This iron and glass structure became an immediate icon, housing exotic plants that residents would otherwise never see in the Midwest. It remains the oldest part of the facility and serves as a primary link to the conservatory’s 19th-century origins. For decades, it stood as a singular testament to grand horticultural architecture in Central Ohio. A major turning point arrived in 1992 when Columbus hosted AmeriFlora '92, an international horticultural exhibition. This massive event prompted a $16 million renovation and expansion, adding significantly more greenhouse space and the Dorothy M. Davis Showhouse. The festival put the conservatory on the international map and fundamentally changed its scale and ambition. Following the event, the facility transitioned from a city-run park to a private, non-profit organization. In 2003, the conservatory’s identity was further defined through a long-term partnership with world-renowned glass artist Dale Chihuly. After a successful exhibition, the Friends of the Conservatory purchased most of the glass installations, creating the largest permanent collection of Chihuly’s work in a botanical setting. These vibrant glass sculptures are now woven throughout the biomes, blending art with nature. This addition helped cement the conservatory as a premier cultural destination rather than just a botanical garden. Recent years have seen the site expand beyond the glass walls to emphasize community engagement and outdoor education. The 2018 opening of the Scotts Miracle-Gro Foundation Children’s Garden added two acres of interactive landscape designed for hands-on learning. The Scotts Miracle-Gro Company Community Garden Campus also provides local residents with space to grow their own food and learn sustainable practices. Today, the conservatory balances its historic Victorian charm with modern commitments to local ecology and the Columbus community. **Maps of the Conservatory** Here is the [main map](https://www.fpconservatory.org/wp-content/uploads/2025/08/franklin-park-zones-scaled.jpg) of the Conservatory grounds. Here's a [map of the areas](https://www.fpconservatory.org/wp-content/uploads/2026/02/ConstructionMap-2026.jpg) in which the Conservatory has ongoing construction (see below). **Summary** For this event, we'll explore Columbus's highly-rated and very popular Conservatory. As mentioned above, the Conservatory is doing renovations on parts of the facility. These renovations are scheduled to be ongoing until the Fall of next year. Basically, no matter when you go to the Conservatory over the next 18 months, you're going to see some metaphorical orange barrels. So let's just go now. **Tickets and pricing** On the first Sunday of every month, the Conservatory is free for residents of Franklin County and the city of Columbus. You must bring an ID to receive this discount. (Yes, they do check.) Otherwise, tickets are $25.20. Members of the Columbus Zoo (of which I am one) do get a discount on tickets, though I have never actually bought a ticket to the Conservatory (I've always gone on free days). I believe the discount is $4. Parking is always free. If you have additional questions about pricing or whether and for what you qualify, you can reach the Conservatory at 614-715-8000. **Where we'll meet** We will meet just outside the main entrance. I guarantee there's going to be a line. The Conservatory is always popular on free days, and especially in nice weather. **Your GPS is stupid!** Be careful simply typing "Franklin Park Conservatory" in your GPS and going where it tells you. The only way to access the parking lot to the Conservatory is off of Broad Street. Unfortunately, since Google Maps is unable to find its way out of a wet paper bag, it has a tendency to want to take people to a mythical, non-existent Conservatory entrance on Nelson Road. If your GPS does this, just drive to the north side of the Conservatory along Broad Street. Your GPS should then redirect you to the main Conservatory entrance. If your GPS doesn't, then throw your phone away\* and look for the big Conservatory sign on the south side of Broad Street between Nelson Road and Franklin Park West. You also should be able to use the map pin I've provided, below, and it should properly direct you to where you need to drive. \* Don't really do this. **After the event** After stopping to smell the roses, for those that are interested, we'll head to the nearby [Columbus Brewing Company Beer Hall](https://columbusbrewing.com/location/beer-hall/) for [drinks](https://columbusbrewing.com/location/beer-hall/#draft-list) and [lunch](https://columbusbrewing.com/location/beer-hall/#food-menu). The Beer Hall's actual address is [200 Kelton Ave, Columbus, OH 43205](https://www.google.com/maps/place/200+Kelton+Ave,+Columbus,+OH+43205/data=!4m2!3m1!1s0x883889a94ac4acad:0xadb2e60240dbc38b?sa=X&ved=1t:242&ictx=111) (it's literally just on the south side of the Conservatory). Be sure this is where your GPS is taking you when you use it, as the Brewing Company has a taproom on Harrison Avenue that is *not* what you want for this event. We should be at the Beer Hall by 1 if you can't make the Conservatory and just want to join us for drinks.

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!
