This is really great - worked on all the pages I've checked so far
This weekend I vibe coded a tool where you can check if sites were created by vibe coding so you can judge other sites for vibe coding whilst you vibe code.
Check it out here: https://vibe-coder-analyzer.pages.dev
What's the lowest score you can find?

I built a ridiculous 1000 pixel display that takes an hour to draw an image and I'm now asking the internet to draw on it (what could go wrong?)

If you use "AI agents" (LLMs calling tools in a loop) you need to be aware of the Lethal Trifecta
Combine access to private data, exposure to untrusted content and the ability to externally communicate and an attacker can trick the system into stealing your data simonwillison.net/2025/Jun/16/...

The folks behind the “State of …” surveys have a new one, and there are zero questions about coding! Instead, the focus is on us. ✨
The questions are about developer interests, health, work preferences, stuff like that. I’m *super* keen to see the results!

OpenAI just dropped GPT-4.1 & a new Codex CLI. The first State of Web Dev AI survey is in: winning tools, what devs are spending, and what’s a pain. Plus: @nextjs.org 15.3 lands, and "slopsquatting" enters the dev lexicon. 🧠⚡️ You don’t want to miss this.

@scott.hanselman.com do you have any guidance for configuring MS Defender for Endpoint on Windows dev machines? We have CPU usage of 10-30% when doing nothing and "Antimalware Service Executable" takes 75% cpu while compiling. We tried excluding folders and DevDrive - nothing seems to work.
