Notes, teardowns,
and opinions.

In November 2025 I wrote that Kimi K2 Thinking was the moment the open-source AI gap closed. Six months and an independent evaluation later, the gap story is broadly right and the Kimi story was broadly wrong. A correction.

React's Activity component shipped stable in 19.2 and has had half a year of production use. The API is unchanged; the patterns and the footguns are now well-documented enough to write down.

Microsoft's Code Apps are now generally available, the CLI is mid-migration, and the pro-dev niche is suddenly crowded with AI-authoring features. What the current shape looks like if you're picking it up today.

Microsoft's Data API Builder quietly became one of the more interesting Azure projects of the year. It still auto-generates REST and GraphQL from a config file, and now it auto-generates an MCP server for AI agents too.
