experimenting with predictive frame interpolation for telemetry dashboards on flaky links. early results: 38% perceived latency drop. naive baseline: render-on-arrival; ours: render-on-prediction with reconciliation on the next ack.

AmberLint v2 now ~9x faster. zero-copy AST traversal was the unlock. lessons: don't fight the borrow checker, design with it. the type system is a free proof assistant if you stop yelling at it.

phosphor decay is not a bug, it's an animation primitive. the modern web should learn from analog. building this very portfolio convinced me: scanlines + a tasteful flicker > 99% of motion design libraries.

found a PVM-1454Q at a thrift store for $40. soldered a SCART-to-component breakout, fed it from a raspi running framebuffer-only linux. typing at 40fps on real phosphor is a religious experience.

spent a week parsing scientific instrument logs. RFC 4180 is a polite suggestion. the actual format is 'whatever the LabVIEW intern shipped in 2009.' wrote a forgiving parser; should've written a strict one and a converter.
