Inside Zig's Incremental Compilation: Millisecond Rebuilds
How Zig's compiler achieves millisecond incremental rebuilds through ZIR, analysis units, and a fine-grained dependency graph.
Rust's Never Type Finally Reaches Stable After Two Years of Work
Rust stabilizes its never (!) type after two years, resolving tricky type-inference edge cases while preserving backward compatibility.
Rust Is a Harness: Why AI Coding Agents Favor Strict Languages
As AI coding agents write more software, Rust's strict compiler and type system turn verification into a competitive advantage over ergonomics.
Scarf Moves From Haskell to Python in the AI Coding Era
Scarf explains why faster LLM-driven code generation made Haskell's long compile times and ecosystem friction unsustainable, prompting a move to Python.
