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.

Please do not arrange to play earlier than the scheduled start time UNLESS you are able to stay till the end of the event, we do not want people leaving early and creating uneven numbers. Hello members, Tennis has become much more popular since the pandemic started and court space has been harder to come by. Following these simple rules will help everyone get the most out of MoCo Topspinners Meetup. • If you RSVP for an event, please attend that event or cancel at least two hours before the event starts. Members that no-show will receive one warning then will be benched (suspended) from events for two weeks. Three no-shows can result in a permanent ban. (No-shows create uneven numbers and prevent folks on the waitlist from playing. Please do your part to un-RSVP as soon as you know that you cannot attend an event.) • Members must have a way to communicate with organizers and hosts. This can be through the Meetup app messages or by providing other contact info. • Any member can ask a host or organizer to have their skill rated for event attendance purposes. You will not be allowed to participate in events higher than your NTRP rating. (We may try to limit numbers or have multiple events on a given day to accommodate players of different skill levels and also to help alleviate the court availability problem). • All members shall conduct good sportsmanship and be courteous to other members at all times. • Sexual harassment, racism, sexism or any kind of intolerance will not be tolerated and will result in the permanent ban from the group. • If member receives three warning infractions, the member will be suspended from the Meetup for a period of one month. If a member is suspended twice (six warnings), that member will be permanently banned and any membership dues will then be forfeited. • If you are scheduling to play with others outside of a MoCo Topspinners event, and you know that there is a MoCo Topspinners event scheduled for that day at that time, please try to use courts other than the courts where the event is scheduled, or move your time so that it does not conflict with the Topspinners event. For a list of complete rules and definitions you can see the MoCo Topspinners front page. If you have questions, don’t hesitate to contact us. We are hoping for a fun season but we may have to wait for courts and leave earlier than we are used to. Please be patient as we adjust to this new normal and try a few different things that will hopefully help the situation. Happy playing! If you would like to attend this event you must be a of minimum 3.0 level. USTA guidelines prior for signing up for the Meetup: https://assets.usta.com/assets/1/15/ExperiencedGuidelines_02142011_V2pdf.pdf • What to bring Tennis Balls, Racket, and Water.

Join us at chef Kevin Tien's new Moon Rabbit location in DC! ***Washington Post:*** Anyone looking for restaurant space should chat up Kevin Tien. After his Vietnamese-inspired Moon Rabbit at the Wharf went dark, the chef says he looked at 30 or so spots around Washington, including the vacated Cashion’s Eat Place in Adams Morgan and Seven Reasons on 14th Street NW. It wasn’t until he toured the onetime location of Co Co Sala in Penn Quarter that he found the right fit: an interior that included a bar near the entrance and an open kitchen. “This is it,” he and his team agreed. “I saw what could be our forever home,” says Tien, “or at least for the run of the lease,” he cracks. Let’s hope he stays put for a spell. His previous full-service restaurants — the Japanese-bent Himitsu in Petworth, the cart- and fermented-food-focused Emilie's on Capitol Hill, the original Moon Rabbit in the InterContinental Hotel — didn’t last beyond a few years. His new roost, 100 or so seats spread across a lounge, central dining room and private area, offers lots of dishes I hope to be eating for a long time. Crab rangoon, for instance. Initially, the appetizer, the provenance of so many American Chinese restaurants, sounds out of place. Tien says it’s a nostalgic nod to the block of Philadelphia cream cheese and topping of Tabasco-brand pepper jelly, slathered on Wheat Thins, that his wife’s parents serve him back in his native Louisiana. At Moon Rabbit, the idea is gussied up with a blend of housemade ricotta and robiola cheese topped with local jumbo crab and eaten with wavy sails of housemade scallion crackers. “Chips and dip,” a server says as she drops off the plate. “The cheese is homage to Laughing Cow,” popular in Vietnam, says chef de cuisine Minsu Son, who cooked with his boss when both were at the late, great Momofuku in Washington. Similarly, the spread is also flavored with imitation crab for a memorable “highbrow, lowbrow” experience. The sight and smell you can’t escape on streets throughout Vietnam is grilled meat, sometimes beef swaddled in betel leaves. Tien elevates the idea by wrapping ground Wagyu beef, perfumed with lemongrass and funky with fish sauce, in easier-to-find perilla leaves that give the meat a minty freshness. Pickled shallots make a zingy garnish and labne dappled with housemade sate sauce becomes a dip for a thoroughly modern bò lá lốt. At the first Moon Rabbit, the chef had to be mindful of travelers and tourists. At Moon Rabbit 2.0, Tien and team, including co-owner and chef Judy Beltrano, are free to be more adventurous. Working in a hotel, the kitchen had to deal with room service, a bar and additional amenities. Now, “we don’t have other distractions,” says Tien. Check out the grilled squid, stuffed with boudin (Cajun sausage) made bodacious with pork, chicken livers, Chinese sausage, jasmine rice, and pops from lemon and five-spice. The server who brought out the combination did a nice job of describing it, down to the charred, squid-inked eggplant puree, which he referred to as “best supporting actress.” Ha-ha and down the hatch. Vegetarians won’t be the only diners to swoon over the beautiful and delicious roasted Lodi squash, the scraps of which are fermented and pureed with coconut milk, garlic and lemongrass to create a vibrant yellow curry. Seeds in the center, a nod to Vietnamese sesame seed candy, include candied pumpkin and sunflower seeds. Flash-fried curry leaves complete the dish, which gives Tien, a co-founder of Chefs Stopping AAPI Hate and the creator of the casual Hot Lola’s, a chance to explain his thought process. With his new restaurant, he hopes to broaden the notion of what Vietnamese food is and break through what he calls “the bamboo ceiling.” Floppy rice cakes come with a crumble of dried tofu that mimics the texture of the more traditional dried shrimp, and purple yams lend their color to the city’s most intriguing risotto, ringed in pureed culantro and beefed up with roasted mushrooms. Bánh canh cua, Vietnamese crab soup, is reimagined with chewy dumplings made from sweet potato and tapioca flours — the kitchen refers to them as “f---ed-up gnocchi” — in a tantalizing, tomato-red broth enriched with crab fat. Vietnam’s long associations with foreign entities allow for such fancies as pâté chaud, flaky puff pastry filled with a meaty interior of ground pork, foie gras, chicken pâté and diced jicama for some crunch. Step aside, beef Wellington. Tien says, “I’m embracing the influences.” Diners are as well. Dinner is not an easy reservation, but the restaurant offers first-come, first-serve seating in the lounge, primarily at the bar. The chef’s crew is mostly composed of staff who have worked with him before, but no investors. So a lot of the look of the place was done on a budget. “Stuff from our basement” make up some of the details, says Tien. Note the great cookbooks lining the shelves here and there. The titles explain the chef’s story and his priorities. If a fire broke out, he says he’d grab "Uchi: The Cookbook", “Prejean’s Cookbook” and “My Vietnam: Stories and Recipes” by Luke Nguyen, reflecting places he’s worked or fellow cooks he admires. Lights that look like parachutes or jellyfish were hung by the staff, and the blue accents are inspired by the Vietnamese coastline. The previous restaurant, the British-themed Scotts, was dark; Moon Rabbit is lighter in every way, signifying “a fresh start for us,” says Tien. All but a few dishes — cumin lamb and quail claypot — are small plates. A couple of combinations could use some finessing. The spring roll is presented as upright bundles packed with hearts of palm, daikon and other vegetables. The trouble is, when you bite into the constructions, their filling spills out. But I love the accompanying sauce, an emulsion coaxed from housemade misos (peanut and sweet potato) and stinging with dried chiles. The bookends are noteworthy. Bar director Thi Nguyen whips up such liquid pleasures as Sài Gòn by Night — coconut-rinsed whiskey, sweet vermouth and lemongrass-coffee liqueur — while pastry chef Susan Bae makes endings as exciting as anything served before them. (Both talents deploy fish sauce in clever ways, too.) Consider Bae’s simply billed and delightfully refreshing “Seaweed”: coconut mousse, a suggestion of seaweed confit, panna cotta — green with the almond-suggestive pandan — rising from a base of chocolate crumbles. The frosty halo on top is frozen coconut milk and lime juice. Tien spends the first part of his day in the kitchen, which is why you see him touching tables throughout the restaurant at night. It’s good to see him back in the game, and fun to think about where he might go next with his food — far, I imagine. ***Check out the menu [here](https://www.moonrabbitdc.com/food)*** We ask that ALL folks honor their RSVP. If you are unable to attend after sending in a YES, please update your status so that others may join. In the event our group incurs a fee for no-shows / late cancellations, your ability to RSVP for future events will be restricted.

If you are unable to join us in May we hope you'll stay interested and join us for a meal in the future. Looking forward to catching up with you for a fantastic dinner at Moon Rabbit!

Today we are Steve's Lab. RSVP and you'll be sent the location. It's in Silver Spring. ***Join us for an evening in an electronics lab where we will attempt to run clean scans of graphene and gold samples, and then clean up that data with post processing.*** This is a high sensitivity experiment, and we do not plan on being successful so early. But we've had promising results lately - so we will be putting in the time. We are NOT meeting at our usual location, but rather at Steve's house/lab. If you RSVP, you will get a DM with the address but it's located in Silver Spring. We will attempt full, clean lab - clean tip repeated scanning tests to see what we can learn and improve. We will experiment with online attendees, but if all possible showing up in person is strongly encouraged.
