Quantum Physics

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.

This month's meeting (May) will be on Quarantine, by Greg Egan. This book deals with a big beautiful huge wall built around the solar system, and some sort of quantum mumbo jumbo about alternate worlds and particles (or waves?) and probably a superposition or two. Who built the wall? Hard to say. Did they make Earth pay for it? Not to my knowledge. Is it big enough to be seen from space? Yes, probably, until observed or measured, at which point it behaves more like a map of the state of New York I assume. LOCATION NOTE: This meeting is scheduled to take place at Micky's Soju House (8450 Baltimore National Pike unit 125, Ellicott City, MD 21043).

[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.

This 1962 historical fiction novel, about the life and last days of the titular Artemio Cruz, is considered a milestone of the Latin American Boom that brought us writers such as Mario Vargas Llosa and Gabriel Garcia Marquez. It explores the corruption of Cruz, a former soldier in the Mexican Revolution, by power. Interestingly, the structure of the book is heavily influenced by "Citizen Kane," with Fuentes attempting literary versions of such film techniques as cross-cutting, closeups, and deep focus.

Brisk 3- to 4-mile urban hike starting and ending at Smoke and Mirrors. We will hike in and around Capitol Hill before returning to Smoke and Mirrors for drinks and food and a spectacular view of of the US Capitol from their rooftop bar.

This is a moderate circuit hike of 7.6 miles with 1320 feet of elevation gain on trails rich in both history and scenery. Adventuring's very first hike occurred 47 years ago this month, as our Founders ventured out in 1979 to Hoover Camp in the heart of Virginia's Shenandoah National Park. It's an exceptionally scenic spot, where two modest streams (Mill Prong and Laurel Prong) merge to create the Rapidan River. Hoover Camp was originally built by President and Mrs. Herbert Hoover as a mountain hideaway and fishing retreat, a precursor to today's Camp David. Though many of the original structures have disappeared, the President's House (a.k.a. the Brown House) and the Prime Minister's Cabin survive to this day. Our hike will begin at Milam Gap, just south of Big Meadows. We'll have one stream crossing at Big Rock Falls before we reach Hoover Camp, where we'll lunch on or near the porch of the Brown House and then explore the rest of the site. Our return route will first use the Laurel Prong Trail and then the Cat Knob Trail to reach the Appalachian Trail, which will take us back to our cars at Milam Gap. We will decide at the end of the hike whether to enjoy refreshments at the charming New Market Taproom in Big Meadows Lodge or somewhere on the drive home. Total length of this moderate circuit hike will be 7.6 miles with 1320 feet of elevation gain on the return leg. Bring plenty of beverages, lunch, sunscreen, sturdy boots, and $5 for the Adventuring trip fee. On the way to the hike, we'll stop at Sheetz in Warrenton so folks can pick up snacks or lunch. Carpool passengers should pay their drivers $20 (assuming each car has at least one rider with a Park Pass, which is usually the case). Meet at 8:30 a.m. on Saturday morning May 23 in the Kiss & Ride Lot of the East Falls Church Metro Station at North Sycamore and 19th Streets, to your right as Metro riders leave the station's only exit.

[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“Popes and Politics,”** on the history of clashes between pontiffs and world leaders, with Vanessa Corcoran, medieval historian at Georgetown University and scholar of the history of the Roman Catholic church. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-popes-politics](https://events.ticketleap.com/tickets/profsandpints/dc-popes-politics) .] President Trump recently shocked many by unleashing personal attacks on Pope Leo XIV, the first American-born pope, in a post on the Truth Social platform. Trump has been widely criticized by religious leaders for these remarks, made in response to the pontiff’s advocacy of peace with the U.S and Israel at war with Iran, and for his separate posts of AI-generated images depicting himself as a pope and as Jesus. For his part, Pope Leo has told journalists, “I am not afraid of the Trump administration,” and has found himself at the center of a heated debate over the proper role of any pope when it comes to commenting on global politics. As unsettling as such developments might be to Roman Catholics, they’re hardly unprecedented. Disagreements between popes and world leaders go back to the Middle Ages, and have played a significant role in shaping the Church and its role in the world. Explore the long history of popes’ conflicts with politicians with Vanessa Corcoran, a historian of the Roman Catholic Church who previously has given excellent talks on papal conclaves and the evolution of nativity scenes. She’ll discuss fascinating developments such as the fourteenth century Avignon Papacy, when Philip IV of France got the upper hand in a feud with the Church by pressuring a papal conclave to select a French pope and then getting the church’s leadership relocated from Rome to Avignon for nearly 70 years. In drawing parallels between recent events and medieval attacks on the Church’s authority she’ll describe how today’s anti-Church memes echo the anti-pope and anti-Catholic images that Martin Luther disseminated in large numbers with the help of woodcut printing. We’ll look at tensions between past presidents and past popes over not just wars, but issues such as abortion, stem-cell research, and abortion access. The talk will leave you with a deeper appreciation of the inherent tensions between politics and matters of faith. (Doors: $17, or $15 with a student ID. Listed time is for doors. The talk starts 30 minutes later.)

**Welcome to Drunken Philosophy** a casual, curious social discussion **Optional topic for this meetup: What's up with all the AI hate?** A recent survey found that 74% of Americans have a negative view of AI, and I want to know why. Come out and debate whether AI is good or bad. My hot take: a labor-saving tool that could potentially help cure cancer gets called dangerous because it might raise unemployment or cause a speculative investment bubble, that tells you a lot more about capitalism and the economic system we live under than it does about the tool itself. As a computer programmer, I think AI is a wonderful tool that has increased my productivity by at least an order of magnitude. I'd go so far as to say Claude Code is the best tool I have ever used. Debate me and name a better one. Is AI potentially dangerous? Yes, but so are a lot of tools. Chainsaws. Steam engines (early ones would occasionally explode and kill everyone in the room). Do you think cavemen sat around debating whether fire could be used as a weapon or for self-harm, and decided not to discover it? I have two friends who hate AI for opposite reasons: one thinks it's a fad and not useful, and the other thinks it's going to take over everything and cause human extinction. Come out tonight, have a friendly debate, and make some friends. No lectures. Friendly crowd. Drop in for one drink and stay if it's fun.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** TBD **YouTube Link** TBD

Let’s meet and wander the galleries! General admission on Sundays is free.

Private Group. Closed to the Public Knowing ourselves and understanding our abilities is the first step toward wielding our gifts with control and accuracy.
