Cubacadabra to unify iOS, Android and web apps around a shared Rust core

Cubacadabra's developers plan to rebuild the product's iOS, Android, and web clients as thin native shells that delegate application logic to shared Rust crates rather than reimplementing features separately in Swift, Kotlin, and JavaScript. The goal is to move business rules like form validation, save logic, and error handling into one Rust codebase that all three platforms call into, citing Litter's Rust-core approach with UniFFI bindings as a precedent.

A writer draws a parallel between the fictional Records of FATE from the game Chrono Cross and today's real-world AI chatbots such as ChatGPT, Claude and Grok.

Canada recruits 48 researchers from leading US universities

Canada has hired 48 scholars away from top American universities in a coordinated recruitment push. The move brings established researchers and their expertise into Canadian institutions, bolstering the country's academic and research capacity.

GlassBox tool exposes what browsers leak to trackers and fraud scripts

A developer released GlassBox, a Show HN project that runs live in a browser to capture the same fingerprinting signals used by tracking and anti-fraud scripts, then displays them to the user instead of hiding them. Users can also paste a JSON report from another browser or session to compare fingerprints, and GlassBox scores similarity to indicate whether the two reports likely come from the same machine, engine family, or browser.
