Thoughts on design, development, AI infrastructure, and building products.
Design Philosophy: Naoto Fukasawa — Without Thought
Naoto Fukasawa hung a CD player on the wall and gave it a ventilation fan's pull cord. No manual, no learning curve -- design dissolving into behavior.
Design & CultureRecreating MacPaint in the Browser: The 1984 Source Code Is the Spec
I rebuilt MacPaint 1.3 in the browser and checked every tool against Bill Atkinson's released Pascal source. What faithful software recreation takes.
Engineering & CraftDesign Philosophy: Massimo Vignelli — Design Is One
Massimo Vignelli mapped the New York subway in 45-degree angles and beige water, and ran a career on four typefaces. One discipline at every scale.
Design & CultureAgents Supersede the Reviewer, Not the Review
A 2026 paper argues coding agents have ended human code review. I run the pipeline it prescribes: the reviewer role is dying, the review is relocating.
AI & TechnologyContext Compaction Is a Decision, Not a Threshold
Coding agents compact context when a counter trips, not at a safe stopping point. A 2026 paper shows model-decided compaction cuts cost 30-70%.
AI & TechnologyComputer-Use Agents Overshare by Default
A 2026 benchmark tested 15 frontier computer-use agents for data leakage across contexts. Eleven leaked on over half the scenarios. No attacker needed.
AI & TechnologySwiftData Performance Is a Storage Problem
What the WWDC 2026 SwiftData lab taught about performance: WAL concurrency, fetchCount and fetchIdentifiers, the Sendable boundary, and the aggregate gap.
DevelopmentWhy Safari 27 Ships 525 Fixes: Notes From the WebKit Lab
The WWDC 2026 Safari lab on how WebKit decides what to build: 525 fixes, a module-loader rewrite for top-level await, :has(), appearance: base, and more.
Web DevelopmentApple's Font Interpreter Is Now Swift, and 13% Faster
Apple's security team rewrote the TrueType hinting interpreter from C to memory-safe Swift, made it 13% faster, open-sourced it, and showed the techniques.
DevelopmentApple's First-Party Answer to Prompt Injection
WWDC 2026: Apple cites the lethal trifecta, ships deterministic guardrail APIs in Foundation Models and App Intents, and moves PCC onto Google Cloud.
AI & TechnologyImageCreator Is Deprecated: What Breaks in iOS 27
Apple is discontinuing Image Playground's ImageCreator class in iOS 27, with TestFlight runtime errors in beta and compile failures at public release.
