This article argues that reliable event-driven systems should be designed for replayability as well as uptime. It introduces the concept of Recovery Contracts, a framework for defining authoritative history, replay boundaries, reconciliation checks, and recovery evidence so teams can rebuild state with confidence after failures.

PC Workman 1.8.0 ships a system monitor that learns each machine's own baseline instead of judging it against generic thresholds: workload-aware temperature buckets (a lifetime Welford accumulator), voltage SPC with Nelson rules, and an offline AI assistant. Built solo, in public, over twelve months, engineering and the personal story behind it.

Why React Native TextInput drops characters when you type fast: the eventCount handshake that does it on purpose, the source behind it, and the fix.

React Native makes TextInput feel controlled, but native owns the text and your JS value is a lagging copy. An eventCount handshake stamps each write; if you typed while JS re-rendered, the counts mismatch and native drops the write on purpose. The leftover dropped characters come from transforms, cursor races, IME resets, and the old architecture. It is worst on a busy chat screen. Fix: keep the keystroke path cheap or go uncontrolled.
