Ruby

Today is about the infrastructure around AI work: computer use, OAuth, PR spam controls, Mac containers, browser compatibility data, and isolated serverless execution.

A heavy Tuesday. HN’s #1 is the formal end of Microsoft and OpenAI’s exclusive partnership and revenue-share — the AGI clause is now history. GitHub Copilot moves to usage-based billing (HN 532 pts, 408 comments). Mercor’s 4TB voice-sample leak puts 40k AI annotators on the public web. pgbackrest stops maintenance and the Postgres community begins migrating. Microsoft drops VibeVoice on MIT — a Whisper-class ASR model with diarization that runs on a Mac with one uv line. Two strong Japan picks: Matz’s own Ruby AOT compiler Spinel, and the CAMPFIRE GitHub-credentials breach postmortem.

Three forces collide in a single 24-hour window: capital concentration (Google reportedly plans up to $40B into Anthropic), a loud quality backlash (a ‘why I cancelled Claude’ post tops HN with 695 points), and an open-weights counter-punch (DeepSeek v4 hits 1,757 points). GPT-5.5 also reaches the API. Plus: Matz’s Ruby AOT compiler, and a quiet note on overthinking.
