Developing provably correct Rust code with Verus
Many open-source and industry software projects, including several here at Amazon, are embracing the Rust programming language, since it provides performance and flexibility similar to that of the C programming language, while its clever type system automatically prevents a variety of bugs and security vulnerabilities. The result is fast code that's more correct and secure than average.

Luke Haas derives music theory from first principles — starting from the physics of sound and working up through frequencies, harmonics, the twelve-tone scale, intervals, chords, and progressions — entirely through code examples. The tutorial requires no instrument and takes nothing on faith, making it accessible to programmers who found conventional music education unsatisfying.

The Best Code Review Says Less
You open a pull request and there are 40 inline comments waiting for you, all from the AI reviewer. It has opinions about a variable name. It wants you to extract three lines into a helper. It found a null that can’t actually occur, on a path that never runs. It’s suggesting a micro-optimization on code that executes twice a day.
