Today's topics:

Claude Code’s hidden agent modes - An unofficial “Claude Code Unpacked” site walks through Claude Code’s public source, revealing the agent loop, tool orchestration, and feature-flagged hints like multi-agent coordination and remote “Bridge” control.

FreeBSD NFS Kerberos kernel bug - A deep security write-up on CVE-2026-4747 shows remote kernel code execution in FreeBSD’s RPCSEC_GSS via NFS + Kerberos, underscoring why prompt patching and careful auth boundaries matter.

Pratt parsing made intuitive - A clear explainer reframes Pratt parsing as a natural consequence of operator precedence and associativity, helping compiler and language-tooling developers implement correct AST building with less mystery.

Why blogging still matters - Daniel Bushell argues that in an AI-saturated web, human blogging is a defense of originality, independent publishing, and authentic expertise—keywords: indie web, authority, privacy, quality.

CERN’s LHC kart April Fools - CERN’s April 1 post joking about levitating “superconducting karts” in the LHC tunnel ties humor to a real milestone: the Long Shutdown 3 work toward the High-Luminosity LHC upgrade.

Dot-sticker inventory for labs - A minimalist inventory trick uses colored dot stickers on clear storage boxes to visualize what you actually use over years, helping makers reduce clutter and prioritize truly essential parts.

Playing chess using only SQL - A fun SQL demo renders an 8x8 chessboard and replays Morphy’s Opera Game using tables and transformations, showcasing SQL’s surprising expressiveness for non-traditional visualization.
