A developer shares their journey of using Claude Code to port their Ruby tools first to Rust and then to pure x86_64 Assembly, resulting in extremely fast performance. They created a 150KB Assembly shell with 9 microsecond startup time and are now developing a terminal emulator and window manager in Assembly. This represents a deep technical exploration of performance optimization through low-level programming.
Background
Assembly language programming represents the lowest level of human-readable programming, offering maximum performance but requiring significant technical expertise. Developers often use higher-level languages for productivity, but some return to Assembly for extreme optimization.
