Quote of the Week

Memory errors are fundamentally state errors, and Rust's move semantics, borrowing, and aliasing XOR mutating help enormously for me to reason about how my program changes state as it executes, to avoid accidental shared state and side effects at a distance. Rust more than any other language I know enables me to do compiler driven design. And internalizing its rules has helped me design better systems, even in other languages.
