I Thought I Had My Own Dark Factory—Then Response Time Died

The web app I’ve been building on my own is finally getting close to Closed Alpha. I’m pretty happy about it. This time, I’ve been seriously trying to develop it in something close to a dark factory style. I say, “I want a feature like this.” AI writes the code. It writes the tests. It runs them. If something is wrong, it fixes it. I check what came out and give it the next instruction. ...

When I traced it back through the old documentation, it looked like Claude Code had once compared something to a train. That sentence survived somewhere in the docs. ...

I Can't Read the PR Claude Wrote for Me

Lately, I can’t read the PRs Claude writes for me. Well, I can still understand the title. “Add feature X,” “Fix bug Y.” So far, so good. It’s the body that’s the problem. Nope. You’ve lost me. What on earth are you talking about? Maybe this is my own fault. I can’t rule out the possibility that watching too many short videos and scrolling X has damaged my ability to read long passages. ...
