Recently at work I managed to hit the Orphan Rules implementing some things for an internal crate. Orphan Rules you say? These are ancient rules passed down from the before times (pre 1.0) that have to do with trait coherence. Mainly, if you and I both implement a trait

Rust's Runtime

Rust has a runtime. No really it does! I blew past that aspect in my most recent post "Oxidizing the technical interview" when I put in the line: The greatest trick the Devil ever played was convincing C and Rust programmers their language has no runtime. and you

Rust and the case for WebAssembly in 2018

Every now and then a technology comes around that fundamentally changes the game and how things work. Java and the JVM created a world where the idea of portable code execution was possible, "compile once, run anywhere" (as long as there was a JVM available). JavaScript changed how
