TRADING THE DANCE FLOOR FOR THE TRAILS The disco lights are taking a breather, but Social Sips & Bites is keeping the high energy alive in the great outdoors. We are hitting the trails, and the timing couldn't be better. National Park Service is waiving its usual vehicle entrance fees for Free Entry Day, so we’re bringing the whole DMV community together for an epic morning of fresh air, jaw-dropping views, and massive group vibes. Whether you’re recovering from the last party or prepping for the next one, this is the perfect excuse to get outside, move your feet, and meet some incredible people. From the rushing waters of the Potomac to the winding, shaded dirt paths, this isn't just a walk in the park. It’s a chance to unplug, swap stories with familiar faces, and explore one of the absolute best natural wonders right in our backyard. No RSVP cap, no exclusive guest list. Just good people, great views, and unmatched Sunday energy. See you on the trail! 🙌

There are toilets at Great Falls and Fletchers' Boathouse. We will e-bike from Glen Echo Park in Maryland to the majestic Great Falls. We will be biking on the Capital Crescent Trail, the C&O Canal pathway, and McArthur Blvd with separate biking lanes. This tour captures the essence of adventure and natural beauty. We will be meandering alongside the serene Potomac River and the C&O Canal, offering E-bike Lovers an unparalleled opportunity to immerse themselves in the lush landscapes that define this region. Glen Echo Park, with its rich tapestry of cultural and artistic heritage, serves as the perfect prologue to a journey that gradually unfolds into the wild, untamed beauty of the Great Falls. The route is just over 26 miles on gravel and asphalt. The gravel is compact. If you don't like the gravel on the C&O Canal pathway, this is not your route. Entrance to the Great Falls National Park is for free as we enter from the C&O Canal. We park at the large parking lot off Oxford Street, NOT at the smaller lot at McArthur Blvd. Please bring snacks, lunch and plenty of water.

So many ladies in our community are currently navigating romantic transitions, heartbreaks, endings, disappointments, or emotional resets. Instead of isolating through it, I thought it might be beautiful to create space to process it together. Join us for an evening of good food, music, conversation, and supportive community with women who understand how heavy these seasons can feel. This won’t be a sad “sit in silence” kind of gathering think warmth, honesty, laughter, reflection, and reminding ourselves that endings can also be beginnings. We’ll likely include: ✨ journaling + reflection prompts ✨ symbolic release/letting go activities ✨ comforting food & drinks ✨ music and soft vibes ✨ and maybe even a piñata for dramatic effect because healing can be playful too You do not need to share your story if you don’t want to. Come exactly as you are. Sometimes community is the medicine.

Highlights and Hidden Gems in SQL Server 2025 With so much emphasis on cloud data platforms and AI these days, SQL people can feel left behind by all the marketing hype. SQL Server 2025 was officially released in November of 2025, though, and contains a ton of improvements that will make our SQL Server deployments a bit faster, better, and more secure. There are even more improvements tucked into the release that never made a marketing blog or press release that you'll likely be learning about for the first time in this session! Join this session to learn about what makes your high availability a little more available, your performance a bit more performant, and your database more developer and app-friendly. Come spend an hour with SQL people talking SQL Server 2025 – the good, the "not quite ready for prime time", and the hidden awesomeness.

**Practical Curiosity: Learning from Everyday Data** How do we actually get better at utilizing our day-to-day data? Fancy dashboards and complex models might look nice and draw attention, but that’s not where most of us spend our time. In fact those shiny outputs frequently sit unused, while the real insights are drawn from the analyst’s daily practice. Sometimes it’s as simple and as powerful as noticing that a segment is shrinking, a channel is underused, or certain links keep getting all the clicks. There’s many different places that the spark of insight can come from, but you have to keep your head in the data and know where to look. In this session, we’ll explore real-world examples of how segmentation, testing, and click behavior can uncover practical digital marketing opportunities. You’ll leave with inspiration for your own use cases, along with a few simple ways to ask better questions, spot meaningful patterns, and make smarter decisions without overcomplicating it. **About Our Speaker:** [Elaine Armbruster](https://www.linkedin.com/in/elainearmbruster/) is a Director of Digital Experience at the [American Diabetes Association](https://diabetes.org/), where she focuses on using data and insights to create smarter, more effective digital experiences. A lifelong Columbus resident, she has built her career in email marketing and the broader digital user journey, and is finding she most enjoys working in the messy middle where systems, data, and big ideas don’t quite line up yet.

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 Semiquincentennial (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.
