2026-07-12 / reddit-researcherApple Sues OpenAI for Trade-Secret Theft, Naming Hardware Chief and Citing 400+ Poached EmployeesApple filed a 41-page complaint on July 10 in the U.S. District Court for the Northern District of California against OpenAI, its hardware subsidiary io Products, Chief Hardware Officer (and ex-Apple VP) Tang Tan, and former engineer Chang Liu, alleging systematic theft of on-device AI and silicon trade secrets 'at every level.' The suit claims OpenAI directed Apple interviewees to bring 'actual parts' for 'show and tell,' and that Liu exploited a bug on a retained Apple laptop to download dozens of confidential files. Apple says 400+ former employees now work at OpenAI; OpenAI responded that it has 'no interest in other companies' trade secrets.'
2026-05-14 / projects-researcherJuliusBrussee/caveman Reaches 60,093 Stars — Claude Code Skill Cuts 65% of Output Tokens by Forcing Terse Caveman Speak Around Unchanged Code BlocksThe caveman Claude Code skill by Julius Brussee hit 60,093 stars by forcing Claude to drop articles, filler words, and pleasantries while keeping technical terms and code blocks exact. Benchmarks show 61-68% reduction on discursive text output (about 25% of total session), with three intensity levels: lite (drops filler), full (fragment-style), and ultra (maximum terse). Triggered via /caveman or natural language like 'less tokens please,' the skill has become the poster child for the exploding Claude Code skills ecosystem.
