The point where log costs overtake compute costs arrives for most organizations. What delays that point isn't the compression ratio — it's the decision about what becomes a field. This post covers field design for struct

Objections are the part most people learning persuasion skip. This post covers steelmanning as a working procedure — restating the other side's argument better than they did, out loud, and getting it confirmed — why rais

A benchmark score is not a property of the model — it is the result of a measurement performed under specific conditions. The incident where the same LLaMA 65B scored 63.6 and 48.8 on the same MMLU at the same time shows

Public benchmarks cannot measure your problem for you, because the input distribution, the definition of a correct answer, and the cost structure of failure are all different. This post walks through, with real code, how

Text, images, and agents all use the word "performance," but their measurement structures are entirely different. Text splits into multiple-choice that pretends to have a correct answer and open-ended generation that has

Persuasion fails at the level of structure long before it fails at the level of phrasing. This post is organized around four axes: establishing a shared premise before you make your claim, putting your strongest evidence

Forward kinematics is a single calculation — feed in angles, get a position. Inverse kinematics can have no solution, several solutions, or infinitely many. This post derives the analytic solution for a 2-link planar arm
