Conceptual, architectural explainers — how a subsystem actually works underneath.
A version-aware explanation of Linux Landlock rulesets, handled rights, parent-directory policy, process inheritance, probing, and safe fallback behavior.
A practical reading of Linux PSI totals, some/full averages, cgroup scope, polling triggers, workload correlation, and capacity decisions without guesswork.
A precise guide to Linux seccomp-BPF actions, filter layering, argument limits, no_new_privs, observability, and the controls a real sandbox still needs.

A correct mental model for macOS FSEvents streams, path coalescing, event IDs, per-disk persistence, dropped-event flags, exclusions, and rescanning.
A map of macOS Network Extension providers, supported use cases, entitlements, configuration ownership, packet flow, privacy, and lifecycle constraints.
A security-aware explanation of Rosetta 2 translation, ahead-of-time and just-in-time paths, code identity, mixed architectures, and compatibility limits.
How Secure Enclave-backed macOS keys combine Keychain references, access-control policy, signatures, device binding, error handling, and recovery design.
An engineering view of emulator audio clocks, sample generation, resampling, buffer control, drift, latency, time-stretching, and deterministic testing.
A preservation-focused guide to MAME CHD hunks, codecs, hashes, parent-child images, metadata, creation, verification, extraction, and version control.
