**Agenda :** * 4.45 to 5.00 PM ET: Food and Networking * 5.00 to 5.50 PM ET: "Hands-On : GitHub Copilot SpecKit" Hello Everyone! Please join us for our April 14th edition of the AI-ML MeetUp. **Please note this is an in-person meeting and light refreshments/food will be provided. You will need a government-issued ID to enter the facility.** **Title:** Hands-On : GitHub Copilot SpecKit **Description:** Spec-Driven Development **flips the script** on traditional software development. For decades, code has been king — specifications were just scaffolding we built and discarded once the "real work" of coding began. Spec-Driven Development changes this: **specifications become executable**, directly generating working implementations rather than just guiding them. In this hands-on lab, we will be covering building your application using SpecKit. Pre-requisites: VSCode v1.107, GitHub Copilot, Python 3.13 + uv, Git installed. **Location:** The meeting will be hosted in the Applied Information Sciences ( AIS ) office in Reston, at 11440 Commerce Park Dr # 600 · Reston, VA. The location is also right off the Silver Line metro's Wiehle-Reston Metro Station. **Parking:** Parking is paid and can be validated at the AIS office reception. We will meet in Room Lake Anne. We hope to see you all there!!!!

We will be meeting at Starbucks to learn together. Come with an online class you're already going through or an interest and we will try to connect you with a course where you can learn it. Already have a skill you want to contribute to a Kaggle Datascience competition? We will work on these too! Laptop required :)

This group is for anyone who wants to explore Buddhist meditation in a relaxed and supportive setting. Each session includes a short meditation, a simple teaching from Buddhist psychology, and an open discussion about how these ideas show up in everyday life. While our foundation is Buddhist practice, we love weaving in wisdom from other traditions whenever it helps us grow, find peace, and support each other. Members of our community come from many different backgrounds, and you do not need to consider yourself a Buddhist to attend. All are welcome. The session runs from 7:00 to 8:00 p.m., with doors open from 6:30 to 9:00. Come early or stay after if you’d like to enjoy some quiet reflection or casual conversation with the community. On the first Wednesday of each month, we share a potluck meal. Bring a dish if you’d like, but the most important thing you can bring is yourself. We look forward to seeing you!

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 9 on "Advanced Quantization Techniques" and Chapter 10, on "Profiling Insights" to understand resource utilization by an SLM. 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.
