I write things down so I stop repeating myself.
Mostly AI and ML. The occasional tangent.

Agents don't need better prompts. They need better permissions
March's agent launches made the shift obvious: once an LLM can read Jira, browse links, and open pull requests, the real engineering problem is no longer prompt wording. It's blast radius.

How preference tuning ruined a perfectly good punctuation mark
A step-by-step trace through the training pipeline that turns a punctuation mark into a writing tic. Tokenisers, reward models, and the labellers who accidentally taught GPT to love polish.
