The architecture, and why I landed on a single-process, write-ahead-logged, deterministic engine instead of microservices or a Kafka log — plus the MVP-to-production roadmap that grows by adding, not rebuilding.

Prediction markets, YES/NO shares, the order book, and price-time priority — explained the way I wish someone had explained them to me, plus how every piece maps onto Polymarket's on-chain stack.

The opening note of a series where I build a production-grade prediction market backend in Rust, one module at a time — and open-source every line of code and every design decision, completely free, no strings attached.

An indie turn-based projectile duel game playable in the browser. Wind, gravity, destructible terrain, 1v1 or 3-player free-for-all, and custom-recorded sound effects.

I discovered 153KB of hidden skill files silently injected into every Claude Code session. By disabling unused plugins, setting up per-project lazy loading, and tuning effort levels, I cut ~63K tokens per session — with zero impact on main projects.

The simplest possible explanation of the three most important Greeks for BTC options — what they mean, the one formula you actually need, and how to pick a strategy based on your market view.
