My Extraction Score Was 0.08 and the Model Was Innocent: Rebuilding the Ruler

41+ min ago   (745+ words) CauterRule is an open-source sidecar that learns standing rules from repeated agent failures. It extracts lessons from trajectories, replay-tests them, and tries to separate reusable guidance from noisy overgeneralization. The last article ended on an open question: at what point…...

100+ Users, Free API Keys and ₹0 Cloud Budget: How I Built Kairos

2+ hour, 1+ min ago   (760+ words) I wanted to build a simple RAG system. That sentence aged badly. The original problem was actually pretty simple. We were organizing a departmental event called Kairos, where participants had to study company information and create pitch decks. The organizers…...

Six Checks to Run Before You Trust a Number Your Own Harness Produced.

2+ hour, 24+ min ago   (1710+ words) I built a measurement harness. I found ten bugs in it. Every one made my results look better than they were, and not one was found by reading the code. Here is the checklist that came out of that. It…...

Ephemora Cell: a capability-based WASM sandbox for untrusted AI code

1+ hour, 56+ min ago   (369+ words) AI agents do not only answer questions. They write code, call tools, and load plugins. The hard part is not starting that work. It is what the code is allowed to do once it runs. Permission systems answer “may it…...

AI Workflow Automation in WordPress: Where the 4WP Plugins Are Headed

2+ hour, 30+ min ago   (475+ words) I'm a believer in architectural approaches — OOP, SOLID, the Essential Principles, DRY — but never all of them, all at once. And nothing beats WordPress Hooks for me: Actions and Filters work small miracles. But today's list has a new entry:…...

A 100 PageSpeed score does not contain INP, and that is the most expensive thing about it

2+ hour, 21+ min ago   (1070+ words) A 100 in PageSpeed Insights is one of the very few numbers in this job you can chase to a literal maximum, which is exactly why people chase it. It is a score, not a feeling, and getting it forces real…...
