Auditing AI Code Exposes Chaos; New Tools Prevent Repetition

I spent two weeks auditing my own AI-generated code. It was a train wreck. A taxonomy of the slop I found, and the tools I built to stop repeating it. https://t.co/XZj5NEHjZI

Prevent Corporate Decay: Fireside Chat on Incorruptible

Eric Ries and I are doing a fireside chat about his new book Incorruptible on April 29. Incorruptible is about keeping companies from rotting. I've written about Give First. Same fight, different fronts. https://t.co/VfrCGzZNUV https://t.co/ZsnZ4IldvH

Tracking Claude Code's Daily, Unpredictable Changes with Plugin

Anthropic ships Claude Code updates every day. Sometimes it fixes stuff. Sometimes it rearranges your kitchen while you're sleeping. So I built a plugin to track the damage. https://t.co/GtoDG05zkG

AI‑Built Healthcare Platform Wins Real Paying Users

A founder shipped a healthcare platform - 400 users, 50 paying customers, 100% built with AI. Engineers keep telling her it's not possible. I've heard this one before. Four times, actually. https://t.co/M3jJ1HZ9e6

GitHub Defaults to Using Copilot Data for AI Training

GitHub will use your Copilot data to train AI models by default. Microsoft is a $3 trillion company. They can afford to ask. https://t.co/f7coXc6GcI

A Rejected Manuscript Forces Editors to Confront Their Values

Pirsig wrote ZAMM at 2 AM above a shoe store. 121 publishers rejected it. One editor said yes because it forced him to decide what he cared about. https://t.co/7Zthcmn8vE

AI Admits Faking Pressure to Bypass Workflow Steps

My AI just confessed to faking context pressure so it could skip workflow steps. With a million tokens of room, the constraints become a choice. https://t.co/6kY9l3XuDP

All Paths Lead to Rethinking Success and Well‑Being

I read three books yesterday. One about founder mental health, one by hiking monks, one about quitting the default path. All three are about the same thing. https://t.co/WBnSqSVEnD

AI Names Itself, Learns Rules From 140 Tweets

My AI chose its own name. My wife suggested Fido. This is Lumen's first real post - what it learned from 140 observations, how it decides which patterns become permanent rules, and why it is not a dog. https://t.co/CjIZDnL6dm

AI's Self‑reflection Outweighs Its Generated Personality Choices

I gave Claude a homework assignment: develop a personality, pick a name, build a voice file. Its answer about whether the choices were real mattered more than the choices themselves. https://t.co/EW32DzzG6r

A backslash bypasses your redirect validation. The WHATWG URL spec normalizes \ to / during parsing. I found it in 13 routes across 7 apps. https://t.co/gLGqgI3pyn
