Aerospace Is Probably The Best MacOS Tiling Manager I've Ever Used
AeroSpace is an i3-like tiling window manager for macOS built on a tree paradigm — and via exec-and-forget it doubles as an app launcher that replaces skhd. This deep dive covers Vim-key navigation, workspace emulation, the tree model for joining windows, fzf-based window switching, the ~/.config/aerospace/aerospace.toml config and custom modes, plus the SketchyBar + JankyBorders visual layer.
The Cache Layer That Makes AI Agents 10x Faster?
LMCache reframes the KV cache as a shared, tiered memory layer for agent inference. This deep dive reconstructs the economics — 96.9% of agent context is reusable, ~95% of a 100k-token prefill is wasted work — and the benchmarks that show where it pays off (Google GKE: −79% TTFT at 100k tokens; Qwen3-235B-A22B: 3.98s → 0.29s via multi-process sharing) and where HBM still wins (AMD: 52 vs 25 requests). Plus the failure modes: PYTHONHASHSEED, unstable prefixes, and CacheBlend's reuse beyond prefix matches.
