Korny’s Blog

I’m not doing a lot of large-scale AI coding at the moment, but I’m still tinkering on side projects when i can.

I was chatting to a friend about my folding bike and I had the urge to write about it - because this falls in the category of “Things I wish I’d had decades ago”.

I’ve completely stopped using Twitter (now called X) and I wanted to post something explaining why.

I haven’t posted in 3 months!

This is a short post (two in one day!)

Note see also my standard AI Disclaimer Update: This post was updated to use the latest Mermaid version, and a few other tweaks. 1 Introduction My last few posts have been rather theoretical, this is back to a “here is how I solved a problem” post.

An expanded version of this post has been published at https://martinfowler.com/articles/agentic-ai-security.html - with more mitigations and updated content - I’d suggest reading that article instead, I’m leaving this one up for posterity.

I’ve had the song “Stuck in the Middle with You” in my head for a few weeks.

I thought it’d be worth posting an example of a bigger task I did the other day - just to show what can be done, without crazy vibe-coding, on a non-greenfields app, using ASP.Net Core not some simplistic front-end tooling.

I was demonstrating Claude Code to a colleague the other day - I was working on an ASP.Net Core C# service, using Claude within the JetBrains Rider IDE.
