See the changelog or try it with npx create-expo-app@latest --template default@sdk-56 🧑‍💻 Articles & Tutorials How's Linear so fast? A technical breakdown (26 minute read) Linear, the issue tracking app, has fast performance thanks to a local-first architecture where the database lives in the browser for near-instant updates, syncing to the server in the background. This is done through aggressive code splitting, asset preloading, granular observables, and a keyboard-centric design with GPU-accelerated animations to minimize all forms of latency. Reliable LLM Inference at Scale (12 minute read) To handle the complexities of multi-tenant LLM serving, Databricks built a specialized abstraction called "model units" that allows for the precise allocation and scaling of GPU resources based on the specific computational costs of different workloads. Integrating these units into load-balancing and autoscaling systems can decrease GPU costs by more than 80% while still making sure latency targets are met even during unpredictable traffic spikes. The Go-To Guide for Understanding Keyboards in React Native (Part 1) (18 minute read) Managing keyboard behavior in React Native is challenging due to the divergent layout and animation APIs between iOS and Android. Using specialized libraries like `react-native-keyboard-controller` is necessary for unifying these platform differences and ensuring a frame-perfect user experience. 🧠 Opinions & Advice How I Use Agents Without Stopping My Own Growth (5 minute read) Effective use of AI agents in software development requires developers to remain intentionally engaged through independent planning and critical code review to ensure the technology enhances rather than replaces their engineering judgment. I think Anthropic and OpenAI have found product-market fit (10 minute read) OpenAI and Anthropic have achieved product-market fit by transitioning enterprise clients to usage-based pricing models fueled by high-value coding agents. This shift demonstrates that AI tools are now essential to daily operations, positioning these labs for significant revenue growth. 🚀 Launches & Tools Clerk API Keys are now generally available (Sponsor) Part of Clerk's machine authentication suite, API Keys let your users create credentials that delegate access to your app's API on their behalf. Enable in the dashboard, manage via the Backend SDK — creation, listing, verification, and revocation built in. Free tier included. Expo UI is now stable: SwiftUI and Jetpack Compose from a single import (10 minute read) Expo UI has reached a stable release with SDK 56, allowing devs to use native SwiftUI (iOS) and Jetpack Compose (Android) components through a single JavaScript import. These universal components reduce native dependencies and allow creating native mobile widgets using JavaScript. Cate (GitHub Repo) Cate is a spatial desktop IDE with an infinite, zoomable canvas for organizing various tool panels like code editors, terminals, and documentation. The platform supports integrated Git management, project-wide search, and a built-in AI coding agent. 🎁 Miscellaneous Tech CEOs are apparently suffering from AI psychosis (6 minute read) Many tech executives are reportedly suffering from "AI psychosis," a delusional overestimation of AI's current capabilities due to their detachment from ground-level work. This misguided optimism has led to massive layoffs and aggressive automation shifts, despite data showing AI has yet to produce enough productivity gains or match human labor quality. What Apple and Google are doing to your push notifications (37 minute read) Apple and Google now use on-device AI to summarize and rewrite push notifications, turning them from direct messages into platform-mediated communications and obscuring visibility for senders. To maintain engagement, senders must shift from broadcast messages to highly relevant, user-triggered alerts and owned in-app surfaces. ⚡ Quick Links TLDR is hiring a Senior Software Engineer, Applied AI ($250k-$350k, Fully Remote) TLDR's Applied AI team is tasked with making every process at TLDR legible to code, runnable by anyone, and composable into larger workflows. Join a small, fast moving team using the latest AI tools with an unlimited token budget. Learn more. The pressure (9 minute read) The curl project is struggling under an unprecedented influx of complex security vulnerability reports that is causing severe developer burnout and is exposing a need for increased corporate funding to maintain the security of its billions of global installations. Training our own AI models (6 minute read) PostHog is training proprietary AI models on anonymized user data to develop "self-driving" product features, such as automated session analysis and synthetic user testing, while providing opt-out controls for customers. Rust (and Slint) on a jailbroken Kindle (5 minute read) A jailbroken Kindle Paperwhite can be turned into a functional smart home dashboard by cross-compiling Rust and using the Slint GUI framework to interface with the device's e-ink display and touch controls. Fully in-browser container builds (3 minute read) Understanding container fundamentals allows for specialized optimizations that can far exceed the performance of standard tooling. Love TLDR?
