Computational Science and Engineering

We’re excited to bring the community together for an evening of learning and connection. This time, we'll have a community member from PagerDuty 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:** Monday, June 29th, 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: **Beyond the Alert: Scaling Incident Response with Elastic, PagerDuty, and MCP**, by Nick Worthington, Senior Solutions Consultant at PagerDuty * 6:30 pm: Q&A with Nick * 6:40 pm: **Observability AI Agents - Behind the Scenes,** by Josh Phifer, Principal Solutions Architect at Elastic * 7:10 pm: Q&A with Josh * 7:20-7:30 pm: Networking & refreshments **Talk Abstracts:** **Beyond the Alert: Scaling Incident Response with Elastic, PagerDuty, and MCP** In this session, we will dive into the next generation of the Elastic and PagerDuty integration. Discover how to leverage Model Context Protocol (MCP) and advanced automation workflows to ingest telemetry, contextualize alerts, and trigger automated remediations. Learn how to reduce MTTR and eliminate alert fatigue, turning your incident management framework into a scalable operation. **​** ​**Observability AI Agents - Behind the Scenes** ​In the age of AI, nearly every observability platform offers some form of intelligent assistance — from automated root cause analysis and incident triage to query generation and dashboard creation. Yet for most users, these AI agents remain black boxes: powerful, but opaque. ​What principles guide their design? How do they reason over telemetry data? And what if you need to customize, extend, or build agents tailored to your organization’s workflows? In this talk, we’ll peel back the curtain on observability AI agents. We’ll explore the reasoning strategies, and orchestration tools that power them. Finally, we’ll dive into how Elastic’s AgentBuilder and Workflow ecosystem enable teams to move beyond out-of-the-box automation - empowering you to shape and build the agent experience your operations demand. **Parking:** * The building’s parking garage is operated by Colonial Parking and is located off N.

Hey Poetry Lovers! This group is on a roll. Here’s the gist: We meet at the **Capital One Café in Chinatown** from **12pm - 2pm** every other week. For enrichment, we start by reading and reflecting on a **“published poem”**, suggested by someone in the group. No advance preparation is necessary. But feel free to check out some of the poems we’ve read [here](https://docs.google.com/spreadsheets/d/e/2PACX-1vSyE_wCLQCPHRrKmN5F9tOIeeRQUZESxjRXGVBoCF2uU8Gm0_d0uECiCBCQXEy6ksxfsBOhtRIOpW3T/pubhtml?gid=0&single=true&widget=true&headers=false%22%3E%3C/iframe%3E). Or submit suggestions for future meetings [here](https://docs.google.com/forms/d/e/1FAIpQLSexGc2Z2Kp6bZW0D3_hfJ7NUUkfNHf7TXX-43FglCeBd9EF2Q/viewform?usp=send_form). Next, we **share our work and offer feedback**. Depending on attendance, everyone gets \~10 minutes to use as they like. (No need to share, though; you’re welcome to come even if you prefer just to listen.) We maintain a **Discord server** to help share our work and communicate outside our bi-weekly meet-ups. If you haven’t used Discord before, take a moment to download it and create an account before arriving. When we meet you on Saturday, we will add you to our server, the “DC Poetry Workshop”, and can help you navigate the app if you have questions. Finally, if you plan on sharing a poem, consider how you will do so. Some options include: * Print 5-10 copies to distribute in person * Take and share screenshots in the Discord chat. * Copy the poem into a google doc, change sharing settings to “anyone with link”, and copy the google doc link into the Discord chat. Most importantly, we’re excited to meet you! Catch you on Saturday, Diego / Ian / Cayden / Nate / Otasha / Lia / An

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

You can sleep in on the Sesquicentennial (observed), we’re shifting to the following Friday. But join the local UX community for a chat and some biscuits to catch up. If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why I’d even want to. Thanks to the team at Nationwide of supporting the group.
