Ship smaller, faster and safer JVM apps with custom JREs

Since Java 9, developers can use jdeps to find required JDK modules and jlink to build custom JREs containing only those modules. This reduces Docker image size, improves startup time, and lowers the security surface. The approach ensures predictable, reproducible runtimes and is the reason generic JREs are no longer released. Multi-stage Docker builds make it easy to integrate this process into production pipelines.

Swift 6 Strict Concurrency - Eliminate Data Races and Boost iOS Performance

Swift 6’s strict concurrency lets iOS developers eliminate data races at compile time. By enabling Swift 6 mode, fixing Sendable issues, applying @MainActor intentionally, using nonisolated for fast paths, and adopting global actors for shared subsystems, teams can improve safety and performance. The result is cleaner, faster, and more maintainable code that scales across threads without sacrificing UI responsiveness.

Jetpack Compose Performance Patterns - Practical Ways to Cut Recomposition and CPU

Jetpack Compose can be fast - if used correctly. Many devs misuse it like XML, causing unnecessary recompositions and jank. This article covers performance patterns using remember for stable objects, derivedStateOf for memoized calculations, snapshotFlow for throttled side-effects, and LazyListState optimizations. It also shows how to debug with Modifier.recompositionHighlighter() to spot problem areas, ensuring smoother UI and lower CPU usage.

React Native’s New Architecture, End to End - With Expo

React Native's New Architecture (Fabric + TurboModules + Bridgeless) delivers faster mounts, lower overhead, and better React 18 support via JSI. With Expo SDK 53+, it’s enabled by default, easing migration. Key steps -> upgrade UI libs to Fabric-ready versions (FlashList v2, RNGH, Reanimated 4), use TurboModule codegen from TS specs, and pin native deps. Expo tools like expo-doctor help ensure compatibility and smooth adoption.
