The source repository for the book '500 Lines or Less', the fourth volume in the Architecture of Open Source Applications series. Each chapter walks through a small program (at most 500 lines of code) that solves a canonical software engineering problem, explaining design decisions and tradeoffs.
Use cases
- learn how compilers, databases, and spreadsheets work by reading small implementations
- study software architecture and design tradeoffs
- find educational code examples for teaching programming
- understand how experienced engineers structure small programs
- learn by reading well-crafted minimal codebases
When to choose
- you want to learn software design through small, readable real examples
- you are teaching or self-studying software architecture
- you want canonical problems (compilers, databases, spreadsheets) explained from scratch
When to avoid
- you need production-ready, maintained software
- you want comprehensive large-scale system documentation
- you need a library or tool to integrate into a project
