Join us for another session of our study group as we dive into the fascinating world of Large Language Models (LLMs) using the book **Build a Large Language Model from Scratch** from Manning. In this session, we will finish **Chapter 7: Fine-tuning to follow instructions**. In the last session, we talked about how to prepare the dataset for instruction fine-tuning and in this session we will perform the fine-tuning and evaluate the model afterwards. 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 build a strong foundation together. If you plan to work with the code on your own laptop during the session, try and set-up the environment ahead of time (https://github.com/rasbt/LLMs-from-scratch/tree/main/setup). We will be meeting at the North County Governmental Center this time that is across from the Reston public library.

This class is a practical, hands-on introduction to creating strong, dramatic portraits using a single light source. We’ll be working in a small studio environment with one model and one light, focusing on how light placement, distance, and modifier choice completely change mood and shape. This is not a lecture-only class—you’ll see the setup demonstrated and then rotate through shooting time yourself. What we’ll cover • How to shape dramatic light with a single source • Light placement for short light, broad light, and high-contrast looks • Controlling shadow depth and falloff in tight spaces • Using minimal gear to create intentional, cinematic portraits • Directing a model efficiently while lighting stays simple What to expect • Small group (10 photographers max) • One shared lighting setup, adjusted live so you can see cause and effect • Time to shoot the model and ask questions as we go • Emphasis on decision-making, not presets or gimmicks Who this is for • Beginner to early-intermediate photographers • Anyone who feels overwhelmed by multi-light setups • Photographers who want stronger, more intentional portraits What to bring • Any camera (DSLR or mirrorless) • A lens in the 35–85mm range is ideal • Fully charged batteries and memory card Lighting gear and model are provided. You just focus on shooting and learning.

In this talk, Sean Hoar will explore how AI assistants can accelerate different stages of software development. From idea generation and prototyping to coding, testing, and debugging, AI tools are transforming how developers work. He’ll provide practical examples of where AI can save time, reduce errors, and help teams focus on higher-level problem-solving. Attendees will leave with actionable strategies to integrate AI into their workflow and stay ahead in the evolving tech landscape.
