A Loop Intelligence Hub guarantees the failure it claims to solve

Robert Glaser has a long post arguing that individual AI productivity gains do not become organisational gains, and that companies need a ‘Loop Intelligence Hub’ to capture which agentic workflows ...

The UK already answered who owns AI-generated code, and it answered it the other way

Sena Evren’s piece on who owns the code Claude Code writes was the most-discussed link on Hacker News this week, and it is a careful walk through human authorship, work-for-hire, GPL contamination,...

Claude Code's hook system just got weaponised

Writing tools for the agent that wrote them

Most of what I have shipped this year has been built using Claude Code. That part is no longer interesting on its own — half the engineering timeline is talking about it. What is more interesting i...
