Longer arguments about systems, cost, and trust

Arguments that needed room. These are about the parts of engineering that do not show up in a diagram: what convenience costs, what trust is made of, and why restraint is a technique rather than a taste.

E-601 The Model That Refuses to Draw — Generative models predict pixels; JEPA predicts what the pixels mean. Why the refusal to reconstruct is the most important architectural decision in world models, and what it teaches anyone who builds systems.
E-602 Minimalism as Engineering — Why less is more in system design: fewer dependencies, fewer features, fewer moving parts, and how to get there without sacrificing capability.

Field notes · details

B-501 Reinforcement Learning After the Reward Model — How reasoning models are actually trained now: verifiable rewards instead of learned ones, GRPO and its descendants, RL compute that scales on a curve, and agents trained inside environments. With the engineering lessons for anyone shipping LLM systems.
B-502 World Models, As Issued: The State of the Set in October 2026 — A field survey of where world models actually stand: V-JEPA 2.1, LeJEPA, Dreamer 4, Genie 3, Marble and Atlas, Cosmos, and a billion-dollar bet in Paris. What shipped, what it cost, and what it is for.
B-503 Experimental UI as an Engineering Discipline — Why treating experimental UI and creative front-end as engineering, not “designer code”, raises the bar for both art and performance.
B-504 Architecture Design for Healthcare AI — How to design AI systems in healthcare: compliance, safety, and the primacy of the clinician in the loop.
B-505 AI in Restaurant Automation — Where AI actually helps in restaurant operations, order prediction, inventory, and kitchen flow, and where it’s hype.
B-506 Systems Thinking for Founders — Why founders who think in systems ship better products and make fewer irreversible mistakes.
B-507 Performance Engineering on Static Hosting — How to hit Lighthouse 95+ and sub-second FCP when you have no server: budgets, critical path, and discipline.
B-508 Building SaaS with a Zero-Dependency Mindset — Why minimizing dependencies is a strategic advantage in SaaS, and how to do it without reinventing the wheel.
