If you’ve worked with LLMs, you’ve probably run into slow inference, out-of-memory errors, or hallucinations you couldn’t explain. There’s no shortage of resources on how transformers work, but most of them either ask you to build one from scratch or get lost in theory that doesn’t connect to the problems you’re actually facing. Transformers in Practice is different. We will give a complete practical view of how transformers work, from how they generate text to what’s happening inside the model to how it all gets optimized to run on real hardware. Interactive visualizations throughout let you see key concepts in action and build intuition that actually sticks. Here’s what you’ll learn: * **Model Behavior:** You’ll learn how LLMs generate text through an autoregressive loop, selecting one token at a time from a probability distribution. You’ll see how sampling parameters like temperature shape the output, why hallucinations happen, and how techniques like RAG, constrained generation, and chain-of-thought reasoning all work within this same loop. * **Model Architecture and Attention:** You’ll look inside the transformer to understand what attention is really doing, how positional encoding tracks token order, and how multiple layers and attention heads work together to turn an input sequence into a next-token prediction. * **Scaling and Deploying:** You’ll learn why GPUs are well-suited for transformer inference and where the real bottlenecks are. You’ll build practical intuition for quantization, KV caching, flash attention, and speculative decoding, including the tradeoffs each one introuces for cost, speed, and output quality. The minimum fee is to pay the venue and avoid no show and make this group of people sustainable in the long term

Let's spend a summer afternoon exploring the area around the River Liffey and Grand Canal Dock. We'll meet at **Mayor Square** at **15:00**, outside Cool Hand, where we can grab a coffee before we set off. After taking some time around the square and the north side of the Liffey, we'll cross either the Sean O'Casey or Samuel Beckett bridge, and walk along the south of the river. Our end goal is to get to Grand Canal Square, which should provide an excellent opportunity for urban landscapes and architecture photography. There are also quite a few options for food and drinks in the area, so we can end our walk in a pub restaurant. If you'd like to stay in touch between events to share and chat about photos, life, the universe, and everything, you can join our new Signal or Telegram group chats, linked below. * [Signal Group Chat](https://signal.group/#CjQKIHwLgV-sbNo5zEs-puKDIuniaus_YfYSdRJTbtwO_MwEEhCiXhPvTTOjK05Ckda4ADzP) * [Telegram Group Chat](https://t.me/+MyFJqkiPZksyNGY0)

## 🤝 Host Information A co-hosted event by ProductTank Columbus & Women in Product Columbus 💡 About the Workshop AI adoption is stalling across organizations — not because of a lack of motivation or tools, but because it's fundamentally a behavior design challenge. This hands-on workshop applies proven Behavior Design models and methods to help you move from a vague organizational wish to boost AI adoption to 3-5 concrete, testable interventions you can act on starting tomorrow. Whether you're a product manager, on a product team, or just someone trying to get AI to actually stick at work, you'll leave with a clear picture of what's worth focusing on, what to ignore, and how to drive real, sustained adoption — no guesswork required. 🛠️ What to Bring Laptop: Fully charged and ready to go. AI Assistant: Have your favorite AI assistant pulled up. (Dom will be using Claude, but feel free to use whichever assistant you prefer!) 🍕 Logistics & Perks Food & Drink: Pizza and drinks provided! Parking: Plenty of free spaces available on-site. ###

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD
