Building with Multiple Languages: A Python-First Approach
summary
Claim: keep Python as the orchestrator and offload hot paths to other languages. Shows concrete patterns and tools: Python as orchestrator, outback monitoring (FastAPI, numpy, websockets), and native bindings for Rust/C++/Zig. Gives performance numbers: 1,000,000 calc: Python 2.1s, Node 0.88s, Rust 0.12s, C++ 0.08s, Zig 0.07s. Builds live demos (real‑time JS charts work), attempts a bushfire simulation (Python version is ~2.25s for 100×100×50 steps; Rust path is in repo), and includes CI/packaging guidance.
