I almost never open Grafana any more. This is the operations architecture that made that true, on under US$10 a month of infrastructure - an agent that reads everything and writes nothing directly, alerts precise enough to act on, repairs that must prove

An agent that remembers across sessions can keep its memory as curated markdown files, as an auto-mined structured store, or as trained experience. I measured all of them: files against a structured store under one fixed model, a store-only head-to-head a

An agent run is stochastic gradient descent over solution space, and steering is how the true objective enters the loop. An optimization view and a Bayesian view that ground the industry ladder - prompt, context, harness, loop engineering - in foundation

One MacBook Pro M4 Max, an open-source MoE, and a hands-on exercise in optimizing it for inference: why the thing that collapses LLM throughput by 100 is prefill, not decode, and the two prefill-side fixes that got it back.

A design walkthrough of how Collection Autofill - a spreadsheet of AI-computed cells - stays fast, fair, and observable from a hundred rows to ten million.

Generative AI is revolutionizing software-how does it transform the way we utilize unstructured data like text, images, and videos?
