Today's topics:

Headphones turned into microphones - A USENIX WOOT paper shows “jack retasking” can flip some headphone ports into inputs, enabling stealth eavesdropping. Key keywords: malware, privacy, HD Audio, Realtek, headphones-as-mic.

Claude Opus 4.7 changes - Anthropic’s published Claude system prompt for Opus 4.7 changed in tone and policy emphasis, while community data suggests higher token usage on the same prompts. Key keywords: system prompt, policy, token costs, Claude Opus 4.7, developer impact.

Typewriters return in classrooms - A Cornell language instructor uses manual typewriter assignments to reduce AI-assisted writing and better measure real proficiency. Key keywords: education, assessment, academic integrity, typewriters, generative AI.

Photonics chips with many lasers - NIST reports integrated photonics that can generate many laser wavelengths on a single chip, potentially shrinking lab-scale optics for quantum and sensing. Key keywords: photonics, lasers, lithium niobate, quantum, optical clocks.

Skiplists reborn for SQL trees - Antithesis explains a “skiptree” approach that makes ancestor queries feasible in SQL analytics by borrowing skiplist ideas. Key keywords: data structures, SQL, BigQuery, fuzzing, timeline queries.

Why game pause is hard - Game developers explain that ‘pause’ often means carefully managing simulation time, menus, and platform overlays—not simply stopping everything. Key keywords: game engines, timescale, performance, certification bugs, pause systems.

Early computing culture preserved - The Internet Archive published BYTE Magazine’s first issue, capturing the DIY microcomputer mindset, alongside a look at pre-GPS navigation with electromechanical computing. Key keywords: computing history, BYTE 1975, preservation, analog computer, navigation.

Landing first consulting clients - An HN thread on solo consulting highlights that first contracts often come from relationships, a clear niche, and visible credibility rather than cold outreach. Key keywords: freelancing, consulting, networking, positioning, SMEs.
