I think, I dig, I build, I write.
Chart Minder's image importer, derived stage by stage: grid detection as projection profiles of edge energy with a median gap estimator, three sampling estimators for a cell's color, and Hartigan's leader algorithm doing the clustering a k-means would be wrong for. With the arithmetic written out, a worked example, and references to where each method comes from.
How LivePhoto's tracking was tuned: a matcher patched to stop locking onto screenshots (6 → 15 inliers plus geometric pose gates), a motion-gated dead-band smoother that kills jitter without adding lag, and a first-frame budget that makes the lock feel free. All numbers from source, all thresholds tuned on real phones.
A personal take on Supabase vs. Cloudflare for side projects — why I left, where Supabase still wins, and the real architecture, performance, and cost differences, with examples from apps I actually shipped.
An honest account of why I mostly stopped shipping agent tools — the cost that keeps moving, the effort that's mostly glue, the fact that everyone is building the same all-purpose agent, and the uncomfortable truth that models improve faster than your code can stay relevant. Plus what I still build, and why research is the real leverage.
