Retro Computing

A developer has released MartyPC, a cycle-accurate IBM PC/XT emulator written in Rust that targets timing fidelity down to individual bus cycles. Separately, a veteran engineer recounted building a GPS navigation system on a 25MHz 486-SX in 1993, a project that predated commercial turn-by-turn software by years.

Testing & Data Tooling

Rapid Dweller's Datamimic generates synthetic test data aimed at regulated industries, positioning itself as a guard against coding agents that hallucinate their own fixtures. The pitch: deterministic, compliance-safe datasets instead of whatever an LLM decides to invent.

Web Infrastructure

Cloudflare has introduced a "disallow AI training" control that lets site owners block crawlers from training on their content while preserving search discoverability, splitting the two use cases that robots.txt has long conflated.

Media & Archives

The Internet Archive published a retrospective on Negativland's 46 years of culture jamming and audio collage, tracing how the group turned sampled media into a sustained critique of copyright and advertising.

Security & Imaging

Apple's security team detailed "Apple Reference Image," a verification scheme that cryptographically attests a photo's provenance at capture time, aiming to distinguish authentic imagery from synthetic or edited content.
