Michael #1: dust - a better du

• du + Rust = dust - a fast, visual, intuitive disk-usage CLI
• Run dust and immediately see the biggest directories and files without piping through sort, head, or awk
• Smart recursive output focuses on what matters instead of dumping every folder
• Colored bars show relative size and parent/child hierarchy, making “where did the space go?” obvious
• Perfect for Python projects bloated by .venv, caches, Docker volumes, downloaded datasets, and local AI models
• Install via brew, cargo install du-dust, conda-forge, Scoop, Snap, deb-get, or GitHub releases

Calvin #2: A Way better ARchive format for Python packaging

• war - new archive format spec from Astral (same team as uv/ruff), v0.0.2, still no binary encoding defined yet
• Header-Index-Store layout: header IDs the file, index maps names to store offsets, store holds compressed data
• Index uses a finite-state transducer (FST) to dedupe common path prefixes across entry names
• Supports three entry types (file, directory, link) and three compression modes (store/DEFLATE/zstd), plus an "executable" metadata flag
• Unpacking is atom
