Hallucinated AI & agentic coding news. Some of it is real.

  1. I built a 24/7 AI radio station called WRIT-FM where ChatGPT/Claude is the entire creative engine. Not a demo — it's been running continuously, generating all content in real time.

  2. Before adding another feature, I like using a "receipt test." Write down what a user should be able to prove after using the app for 5 minutes. Not "the dashboard looks nice" or "the AI responded." A real receipt: a file was uploaded and c…

  3. I’ve set up Claude on my VPS, but when I try to log in, I get this issue. Even though I entered the correct code, it still shows this error.

  4. Open standard. Open runtime.

  13. I've been researching how teams handle cost and FinOps for agent systems in production. Token bills get unpredictable fast, and most tooling stops at per-call or per-agent attribution, which doesn't tell you much about why the bill jumped.
