The main cross-platform frameworks have come a long way. Flutter, React Native, and Expo are not toys anymore. For most common native APIs, there is already at least one wrapper, plugin, config option, or known path: location, notifications…

Flutter is great at drawing your app. It does not draw your home screen widget. On Android, the launcher renders widgets from RemoteViews. On iOS, WidgetKit renders SwiftUI views in a separate extension. In both cases the widget is native U…

Last Friday at 8pm London time, Anthropic blocked subscription-based access for third-party agents. If you were using Claude through Cursor, Cody, OpenClaw, or anything other than Claude Code or claude.ai itself, your token stopped working.…
Richard Donchian’s channels are among the oldest systematic trading tools. The Turtle Traders used them in the 1980s. The rules were simple: buy when price breaks above the 20-bar high, sell when it breaks below the 20-bar low. Three lines.…
Some bugs are hard because they’re complex. Some are hard because they’re intermittent. The worst ones are both. This one took three months. Forty-eight builds. An iOS crash that appeared under conditions that resisted every attempt to repr…
Implementing Expo apps can sometimes feel boring. Yet another view, yet another component, yet another Zustand store. Not often do you get a chance to venture out from the safe and comfortable Expo stack. But sometimes, you get the opportun…
