I made two AIs review each other's code for 30 days. A human still caught the bug in 5 minutes.
30+ min ago (905+ words) Last month I let AI write 100% of my code for 30 days. The single loudest lesson wasn't "AI is amazing" or "AI is useless." It was one sentence: the thing that writes the code can never be the thing that reviews…...
AI Website Handoffs: When a Prototype Needs a Real Code Boundary
27+ min ago (332+ words) A polished AI-generated website can hide an unfinished delivery model. The hard question is not whether a builder can produce a convincing page. It is whether the next person can safely change the real system without reconstructing the original prompt,…...

39+ min ago (305+ words) MCP is JSON-RPC over stdio / Streamable HTTP with bidirectional notifications. Normal HTTP chaos tools don't speak it. And even when you test an MCP server, you usually test your agent, not whether the server's contract protects you. Real failures I…...
56 fault-injection tests passed. The one that injected nothing failed.
59+ min ago (415+ words) I was building a tool that detects when data quietly changes meaning — a vendor switching units, a source dropping a field, an undocumented enum appearing. The kind of failure where every test passes and every job is green. Claims about…...
Three things that bit us moving a document scanner fully into the browser
1+ hour, 9+ min ago (596+ words) I work on LensUp, which does exactly that — the whole pipeline runs in the tab, and files are never uploaded. Disclosure up front: it's our tool, and this post is about the parts that were harder than the pipeline itself....
