Today's topics:

Dictionary compression reshapes web delivery - HTTP dictionary compression via RFC 9842 and Zstandard/Brotli dictionaries can slash repeat-visit payloads—tests cite up to 90% smaller JavaScript than Brotli, with Chrome 130+ leading support.

Encrypted RCS finally crosses platforms - Apple and Google are testing end-to-end encrypted RCS between iPhone and Android under the GSMA Universal Profile, bringing lock-icon encryption to cross-platform chats in iOS 26.4 beta and Google Messages beta.

Meta’s massive AMD chip bet - Meta signed a five-year, $60B purchase agreement for AMD AI hardware and took a 10% stake, signaling a major shift toward inference-optimized accelerators like MI450 and multi-vendor compute strategy.

Model distillation, data, and security - Anthropic alleges Chinese startups used 24,000 fraudulent accounts to generate 16M Claude conversations for distillation, raising terms-of-service, safety-guardrail, and national security concerns around model copying.

AI coding era: quality and juniors - Microsoft leaders warn AI agents can boost seniors but slow juniors, while Simon Willison pushes red/green TDD as an agent prompt; the shared theme is verification, tests, and mentorship to avoid brittle code.

Robots, Mars autonomy, and navigation - China showcased more capable humanoid robots amid booming shipments, while NASA gave Perseverance a Mars ‘GPS-like’ localization upgrade—both point to faster autonomy, but with real-world robustness still a question.

Geothermal’s scale test and economics - Geothermal companies are diverging: EGS drilling gains may plateau while closed-loop systems target district heating economics; scalability hinges on rigs, capex, water losses, and siting near transmission or data centers.

Gene editing precision and FDA pathway - Researchers reduced base-editing bystander mutations by over 80% using linker redesigns, as the FDA detailed a ‘plausible mechanism pathway’ for bespoke ultra-rare genetic medicines—promising, but still bounded and early.

Export controls and tech geopolitics - China imposed export restrictions on Japanese entities tied to military capability, and Washington launched a Peace Corps-style Tech Corps to promote US AI abroad—highlighting the tightening tech-and-supply-chain contest.

IPO float shock and software selloff - A scenario analysis about an ‘intelligence crisis’ sparked a software-stock selloff via SaaS pricing risk, while a separate IPO-float argument says SpaceX/OpenAI/Anthropic public listings could strain index flows and market liquidity.
