Notes from X

A few selected thoughts on engineering and building software. Each excerpt links to the full post on X.

  1. We built software free as in open and got free as in beer thrown in. Grow the bazaar and get cathedrals too.

  2. I've been building data pipelines and workflows for years in different industries. I finally got around to making the OSS package I wanted to improve this type of work. It's fun, fast, and feature packed.

  3. There's a divide how firms are thinking about making existing software "agent native":

    • Approach A: Add an MCP server, maybe add a CLI, add auth tokens. 'Use our Claude integration'
    • Approach B: The application == the agent. Requires totally new approach.
  4. Buy vs Vibe is the eng leadership discussion of 2026.
