• Here's one of the many little ways that AI is changing expectations about UI. I'm building this thing I want for teams I manage to more clearly define review points. (A bit like Shopify's phase transitions in their GSD system). I have a handful of tasks that should be checked in a review. It used to be normal practice that any list in a UI needs a title. Eg "List" or "Untitled" etc. But this was always a drag, right? Naming a list just to have a group of things is extra work. But without a name it's hard to scan and find and all lists look the same. Now AI can generate titles for anything. Li…

• Large parameter lists that rely on positional string arguments are a weak interface for both humans and coding agents. Yet they’re just a symptom. More often than not, the root cause is a function that does way too much. In my new post, I explore the problem and walk through a refactoring that encapsulates data and behavior in explicit domain concepts.
