Mastering Chat-Oriented Programming with Stephan Janssen
In this episode I’m continuing my chat and pairing with Stephan Janssen, founder of the Devoxx conference empire and author of the Devoxx Genie AI plugin for IntelliJ https://github.com/devoxx/DevoxxGenie...
Last week ( • Devoxx Genie AI Deep Dive with Stepha... ) Stephan helped me understand how chatting with a large language model is implemented. Armed with this knowledge, this week we open up the Gilded Rose stock control codebase and attempt to use the Anthropic API to understand something of what it does, and ask the LLM how to remove a now-redundant piece of configuration.
Working with an expert has given me new techniques for chat interactions, techniques that improve my success rate, but at the same time made me realise that I may be asking too much of the current state of the art. Stephan’s enthusiasm is infectious though, and makes me believe that interacting with AI systems will be as much part of a modern programmer’s toolset as becoming expert in an IDE, testing tools, refactoring techniques, and so on.

If you like this video, you’ll probably like my book Java to Kotlin, A Refactoring Guidebook (http://java-to-kotlin.dev). It's about far more than just the syntax differences between the languages - it shows how to upgrade your thinking to a more functional style.
