You're absolutely right, it was your home directory!
Letting an AI agent loose for solving development tasks is a productivity dream, until it decides to optimise your home directory or brick your system by upgrading Python. We want that YOLO mode speed, but without the security nightmares. In this session, we’ll look at Docker Sandboxes: a new primitive designed to let agents operate in a restricted cocoon with limited access to the filesystem and controlled network and secret injections. We’ll dive into the typical mess AI agents create, see why basic isolation isn't enough, and walk through a workflow for running agents that you can actually trust.
Building AI workflows: from local experiments to serving users
Everyone can throw together an LLM, some MCP tools, and a chat interface, and get an AI assistant we could only dream of a few years back. Add some “business logic” prompts, and you get an AI workflow; hopefully a helpful one.
But how do you take it from a local hack to a production application? Typically, you drown in privacy questions, juggle npx commands for MCPs, and end up debugging OAuth flows before it hopefully starts to make sense.
In this session, we show a repeatable process for turning your local AI workflow experiments into a production-ready deployment using containerized, static configurations.
Whether you prefer chat interfaces or replace them with application UIs, you’ll leave with solid ideas for going from a cool demo to real applications without the existential dread of DevOps.
Ignore All Previous Instructions, But Like For Real
Have you ever dreamt of AI that is truly yours? Not the crude "let me stuff some details into the context of gpt-X and hope it works out", but truly having a model that is specific to problems you want to solve?
Realistically though, you won't be training half-a-trillion parameter models, and smaller ones which you can wrangle locally lack quite the je ne sais quoi of general intelligence.
The solution, of course, is fine-tuning! Which, if you're an application developer, looks scary and smells like Python and years spent on Ph.D in machine learning.
Let's make it more approachable! This session will demystify the world of fine-tuning, transforming it from a scary machine learning discipline into a practical application development tool.
We will cut through the jargon to make you less likely to start daydreaming about Spring Boot when someone mentions pokemon sounding machine learning words like LoRa or Unsloth.
You'll learn how to leverage tools developers use every day to fine-tune small, high-performance models, for example Gemma 3n, for custom tasks. And leave with the courage and concrete knowledge to start adapting LLMs' behavior to your problems at hand.
Your GPU misses pixels: 3D world-building with OSS
I got a mini drone for Christmas and, boy, did that open a rabbit hole. It turns out your GPU is capable of a lot more than just predicting the next word in a chat...
In this session, I’m going to show you how to take a collection of photos and turn them into a high-fidelity 3D models. We’re going to dive into what Structure from Motion and Gaussian Splatting are and how they work. We’ll look at a complete open-source pipeline: from the initial analysis and training to actually editing the rendered models.
If you feel like you have to touch the grass sometimes and want to do it in style, grab any device with a camera and come join me on this journey into the 3D world.
