THE DIFF
Faster in TypeScript? The WASM Overhead is Real.
OpenUI replaced a Rust-based WASM parser with a native TypeScript version, resulting in a 3x speed increase. The performance bottleneck was not Rust’s execution speed but the constant data serialization and memory copying required to communicate between the JavaScript runtime and the WASM module. For frequent, small data operations, the overhead of the WASM bridge negated the benefits of native code execution. It’s a solid reminder that the fastest code is the one you don’t have to call across a foreign function interface.

Your Fitness App is an OPSEC Nightmare. Again.
Journalists from Le Monde successfully tracked the live location of France’s flagship aircraft carrier using public data from a fitness tracking app. By correlating jogging routes uploaded by personnel with the ship’s known deployments, they pinpointed its position in the Eastern Mediterranean. This incident mirrors the 2018 Strava heatmap issue that exposed military bases. Apparently, some lessons require multiple, very public failures to be learned.

RARE EARTH
AT Protocol… in Fortran.
fortransky is a terminal-based client for the decentralized AT Protocol network (Bluesky), written entirely in modern Fortran. It uses the json-fortran library for parsing and Fortran-unix for system calls, supporting basic timeline viewing and posting. The project demonstrates the surprising viability of a 60-year-old language for interacting with modern, JSON-based web APIs. It’s an impressive, if utterly impractical, piece of engineering.

TOOL OF THE WEEK
Tool of the Week: OpenCode Agent
OpenCode is a new open-source AI coding agent designed to operate directly within your local development environment. Unlike cloud-based assistants, it has full context of your file system, can run commands, and execute tests to validate its own changes. It’s built on a command-line interface and aims to be a self-hosted alternative to tools like GitHub Copilot Workspace or Cursor. While it’s early, having a transparent, locally-run agent you can actually inspect is a compelling proposition.

Microsoft Admits Windows 11 is a Mess, Pledges to Fix It.
Responding to sustained criticism, Microsoft has publicly committed to improving Windows quality, performance, and reliability. The announcement from Windows chief Pavan Davuluri outlines plans to reduce AI bloat by rolling back some Copilot entry points, end forced updates by allowing indefinite pausing, and restore core UX features like a movable taskbar. The changes signal a significant strategic retreat from the feature-first approach that has plagued the OS for the last few years.
