Digital Forensics

Today we are Steve's Lab. RSVP and you'll be sent the location. It's in Silver Spring. ***Join us for an evening in an electronics lab where we will attempt to run clean scans of graphene and gold samples, and then clean up that data with post processing.*** This is a high sensitivity experiment, and we do not plan on being successful so early. But we've had promising results lately - so we will be putting in the time. We are NOT meeting at our usual location, but rather at Steve's house/lab. If you RSVP, you will get a DM with the address but it's located in Silver Spring. We will attempt full, clean lab - clean tip repeated scanning tests to see what we can learn and improve. We will experiment with online attendees, but if all possible showing up in person is strongly encouraged. Online join link is: - [https://meet.jit.si/mocomakers](https://meet.jit.si/mocomakers) Our community is building (and documenting for other teams) how to build a scanning tunneling microscope using a mix of common and 3D printed parts. This will allow us to scan and visualize a single atom - an ambitious we are doing over the course of a few months. The MoCo Makers community is one of the most innovative and competent groups in Maryland, and we've done everything from [publishing cancer research](https://pubmed.ncbi.nlm.nih.gov/38136356/), to [launching products](https://www.kickstarter.com/projects/gotim/cozy-curvy-multi-contour-pillow), [winning grants](https://covidinfocommons.datascience.columbia.edu/awards/2014255), and inspiring thousands. Now our biggest challenge yet has appeared. We are building a Scanning Tunneling Microscope, that will allow us to scan and visualize single atoms. To get a better idea of what we are doing, see our reference project here: [https://www.youtube.com/watch?v=7N3OqTEq08g](https://www.youtube.com/watch?v=7N3OqTEq08g) All starting CAD, code, and reference files should exist. However, let's be the first Maker community to document the build process and share it with learners around the world. We will be publishing our work here -[ https://hackaday.io/project/202816-qt-panda](https://hackaday.io/project/202816-qt-panda) If you need a ride, let us know.

**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.

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.
