Doubles Volleyball - Competitive BB-A level @Bluemont Park Let's get together to play some fun A level Doubles games at Bluemont. Format: Doubles COST: FREE Court Type: Outdoor grass Minimum Skill Requirements: A level (click [here](https://docs.google.com/document/u/2/d/1PojSi4qdlRsv1msCHhvpQ43iDc4FfzQwpWCc3kafVMY/mobilebasic) for details) Attention: 1. This event is not always on a first come, first served basis. Those who can bring a net and ball, may get priority over others on the waitlist. 1. Since skill levels are self-reported, some attendees may not meet the expected level in reality, so we encourage you to choose a partner you can enjoy the game with, and since this is a competitive event, it is okay if you make a strong team and win all the games. 1. Since people arrive at different times, each group of 1. Players will set up and claim a net as they arrive, and may continue playing without rotating until all nets are set. ——— Smiley Social documents: [Group Rules](https://docs.google.com/document/u/2/d/1HrG35p_0M08leRvCp8XWG3CMkr_GL928XFabl5T6Dvg/mobilebasic) [Liability Waiver](https://docs.google.com/document/u/2/d/1W2mq-7m99lmvd7gdWYaSUFtvVg4UGnzV6koafAbHmco/mobilebasic) [Volleyball Levels](https://docs.google.com/document/u/2/d/1PojSi4qdlRsv1msCHhvpQ43iDc4FfzQwpWCc3kafVMY/mobilebasic)

[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“How AI Alters Thinking,”** on dealing with artificial intelligence’s capacity to change and undermine our thought processes, with Eli Alshanetsky, assistant professor of philosophy at Temple University, principal investigator at its Cognitive Integrity Lab, and author of an upcoming book on AI and freedom of thought. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-how-ai-alters-thinking](https://events.ticketleap.com/tickets/profsandpints/dc-how-ai-alters-thinking) .] Doctors who give bad advice can be sued for malpractice. Teachers belong to a profession with set standards. When artificial intelligence guides you, however, that guidance comes with a disclaimer: Use at your own risk. Every day millions of people take that risk, and usually AI seems genuinely helpful. But even if AI gives us good answers, might its use over time do bad things to how we think? Explore the relationship between AI and our own minds with Eli Alshanetsky, whose Cognitive Integrity Lab studies how artificial intelligence changes how we think, learn, and build trust. Author of *Articulating a Thought* and the upcoming book *Freedom of Thought in the Age of AI*, he’s on the cutting edge of efforts to answer AI-related questions such as: How can we tell when work is truly our own? How can technology support rather than replace authorship and reflection? What does trust mean when AI mediates our relationships with others and with our own thoughts? To set up his discussion of potential consequences of AI, he’ll describe how social media’s impact on society serves as a preview. Social media didn’t just give people what they wanted to click on, it actually changed what they regarded as click-worthy. It broke attention spans and fueled radicalization across millions of very different people. It left us with people who doom-scroll for hours, who can’t focus, who don’t know what to trust anymore. If you’d shown people this version of themselves ten years ago, would they have chosen it? Artificial intelligence is making a similar deal with us, but the stakes are higher. It isn’t chasing clicks. It’s optimized for giving you the most satisfying response to whatever is on your mind right now. The risk over time isn’t just that you’ll get lazy. More profoundly, even when you think hard, your sense of what counts as good thinking—as well as what sounds like you—will shift to match what AI has been feeding you. We’ll consider what kind of person this produces and whether this is someone we want to be or want children to become. Professor Alshanetsky will lay out a practical framework, which he calls “the interaction layer,” for using AI without letting it replace the thinking it’s supposed to support. He’ll also talk about what AI-related concerns should be the focus of parents and educators. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.)

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.

**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.

We will show how to build custom agents with Microsoft Agent Framework. Attendees will learn how to build and custom host agents when Microsoft Foundry is not a viable option.
