Week-over-Week Trends #

  1. AI Security Research: Major shift with Anthropic’s Mythos finding real vulnerabilities in decades-old code. AI bug reports “went from junk to legit overnight” per Greg Kroah-Hartman.

  2. Supply Chain Security: Multiple high-profile attacks (Trivy, Axios, WordPress plugins, Nix) highlighting the fragility of open-source dependencies.

  3. Open Source AI Policy: SDL and Vim establishing formal policies against LLM-generated code, reflecting growing concerns about provenance and licensing.

  4. Legacy Hardware Deprecation: Linux removing support for i486 and ancient architectures while adding cutting-edge support for AMD/Intel latest silicon.

  5. Enterprise AI Adoption: Gap growing between frontier AI and enterprise-accessible models; companies preferring smaller, specialized, self-hosted solutions.
