In this episode, we have a look at some causes of race conditions and go about some ways to troubleshoot and mitigate them.

In this episode, we explore the practical use of Campfire Bots for webhook applications. We'll start by setting up an AI Image Generator bot that interacts with our Ruby on Rails application, and then connect it to a self-hosted Large Language Model (LLM). Our initial goal is to get the system working. After that, we'll focus on refactoring the code to improve its safety and maintainability.
