  Vercel Labs Unveils scriptc, a TypeScript-to-Native Compiler

  Vercel Labs has released scriptc, an experimental compiler that turns TypeScript into small native executables without using Node.js, V8, or any JavaScript engine. It uses the TypeScript compiler for type checking and can generate C or WebAssembly, with early tests showing faster startup and lower memory use but slower execution than Node.

  Cloudflare revisits remote Spectre attacks on Workers

  Cloudflare re-evaluated remote Spectre attacks against its Workers runtime and found a limitation in its Dynamic Process Isolation defense. The company demonstrated a reliable attack in production conditions, then improved mitigations by strengthening DyPrIs, adding the V8 Sandbox, and introducing an in-process isolation mechanism. Cloudflare says the issue is already mitigated in production and no signs of active exploitation were found in the past three years.

  Chrome 148 Makes Math.tanh OS-Fingerprintable

  Since Chrome 148, V8 uses the host platform's math library for Math.tanh, causing the function to return slightly different floating-point results on Linux, macOS, and Windows. That makes tanh() a small but usable fingerprinting signal that can reveal the underlying OS and create inconsistencies for browser spoofing systems.
