Reactive Programming

**Agenda:** * 6-6:30 pm: Networking and food/drinks * 6:30-7:15 pm: Announcements and presentation * 7:15 pm-7:30 pm: Q&A and close-out **Hacking the Stack: Using OpenSearch Dashboards as an Application Framework** Most developers treat OpenSearch Dashboards (OSD) strictly as a visualization layer—a place for charts and graphs. They are missing the bigger picture. OSD is a powerful, untapped environment for full-stack application development. In this session, we peel back the architecture of **an enterprise-grade risk, compliance, and security platform built entirely *on top of* OSD**. We moved beyond simple plugins and pushed OSD to its limits to create a seamless, interactive application experience. Join us for a deep dive into the engineering reality of the OpenSearch stack, including: * **The Analysis:** Why the OpenSearch stack beat out the competition. * **The Build,** **Beyond Visualization:** How to implement custom React components to build complex workflows and interactive UIs within OSD. * **The Integrations:** Integrating Wazuh for agent management and ingesting data at scale. * **The “Gotchas”:** Honest, real-world lessons on data handling, state management, and what to look out for. **If you are ready to push your plugins from “reporting tools” to “robust software,” do not miss this session!**

But building thousands lines of production Swift taught me: AI can get you 70% there but expertise is still required. From skeptic to pragmatic builder, I'll share when AI shines, where it fails, and how to thrive in the AI era. No hype, no doomerism—just reality.

Join us for another session of our study group as we continue our coverage of the book Domain-Specific Small Language Models. In this session, we will attempt to cover Chapters 5 on "Exploring ONNX" and Chapter 6, on "Quantizing for your Production Environment". This isn't just a lecture! Come ready to ask questions, share insights, and code along. Whether you're a beginner or have some experience, this is the perfect opportunity to continue to learn together. If you plan to work with the code on your own laptop during the session, try and download the code from here https://github.com/virtualramblas/Domain-Specific-Small-Language-Models ahead of time.

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“A Practical Guide to Social Change,”** a research-based look at how communities bring about reform and progress, with Marissa Robinson, founder of Real Health Impact LLC and an adjunct professor at George Washington University who teaches courses focused on public health leadership and social change. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-social-change](https://events.ticketleap.com/tickets/profsandpints/nv-social-change) .] Systems built on inequality rarely transform without deliberate pressure from the people most committed to justice, because progress takes coordination, conviction and willingness to change what has always been accepted. Real change starts when people choose to move together. Learn what research and experience say about how to make real social progress with Dr. Marissa Robinson, a public health practitioner who previously worked in federal agencies coordinating global and national public health initiatives focused on infectious diseases, HIV, and health equity. Among the key questions she’ll tackle: How do communities overcome barriers to create real change? When should evidence guide decisions and when does context matter more? She’ll discuss established frameworks for moving from intention to measurable progress and talk about the importance of building coalitions that actually work and of making decisions grounded in real data. You’ll learn about the importance of testing ideas on a small scale before going big, as well as how to use rapid feedback loops and continuous improvement cycles to refine approaches and scale what truly works. Dr. Robinson will share stories of ordinary people and communities who refused to accept the status quo and pushed through real barriers to achieve breakthrough results. She’ll talk about practical strategies, usable frameworks, and evidence-based examples that people can apply immediately in their own communities and organizations to support change that lasts. If you have dreamed about bringing about progress in your world, this talk will give you the clarity, direction, and confidence it takes to turn such dreams into reality. ( Door: $17, or $15 with a student ID. Listed time is for doors. The talk starts 30 minutes later.) Image by Canva.
