We rewrote our Rust WASM Parser in TypeScript – and it got 3x Faster

tech2 sources

A team rebuilt their Rust-to-WASM parser in TypeScript and achieved a 3x speed improvement. The bottleneck was not Rust's execution speed but the WASM-JS boundary overhead—serializing/deserializing data between runtimes. Eliminating the boundary entirely by rewriting in TypeScript, which runs natively in V8, removed the overhead and significantly improved streaming latency.

Brow (Why We Built Brow in Swift, Not Electron)

tech2 sources

Brow was built as a native Swift app instead of using Electron because deep macOS system integration—window management, clipboard, hardware stats, accessibility hooks—requires direct access to native frameworks. The article contrasts this with Raycast's approach of a native core with a React/TypeScript extension ecosystem, arguing that while web-based extensions boost ecosystem growth, they introduce mediation overhead that conflicts with tight system-level product design.

Trump’s AI framework targets state laws, shifts child safety burden to parents

tech2 sources

The Trump administration released a legislative framework to create a unified federal AI policy, preempting state-level AI regulations in favor of a centralized, innovation-friendly approach. The framework outlines seven objectives prioritizing AI growth and scaling, places child safety responsibility largely on parents, and proposes nonbinding expectations for platform accountability. White House AI czar David Sacks champions this light-touch regulatory strategy, which critics may see as undercutting states' recent efforts to regulate AI development and use.

What Your IP Address Actually Reveals (A Developer's Perspective)

tech2 sources

Every HTTP request carries the sender's IP address, which reveals more than just geography—including ISP, organization, ASN, connection type, and proxy usage. IP geolocation is accurate to the country level (99%+) but drops significantly at the city level (50-80%), with mobile and VPN IPs being particularly unreliable. Beyond location, IP lookups expose organizational ownership via WHOIS data and ASN, enabling developers to categorize traffic for rate limiting, fraud detection, and access control.
