This article demystifies the C4 compiler—a minimalist C compiler written in just 528 lines and four functions—by explaining its architecture, showing a Hello World build, demonstrating self‑hosting, and detailing the supported language subset, bytecode format, and unique implementation tricks.
This article explains how to keep software architecture simple and appropriate by applying KISS principles, balancing completeness, flexibility, and lightness, outlines when pre‑design is sufficient or excessive, presents core design principles such as SOLID, N+1, statelessness, and details a six‑step C4‑based design and review process.
This article explains the purpose and value of architecture diagrams, defines key concepts, outlines five common view types, discusses criteria for good diagrams, highlights common pitfalls, and introduces the C4 modeling approach with examples to help engineers communicate system designs effectively.
This article explains the design, phases, and practical implications of the C4 concurrent continuously compacting garbage collector, comparing it with G1 and IBM's Balanced GC, and provides guidance on when to choose C4 for enterprise Java workloads requiring low pause times and high scalability.
