"Loved reading this excellent post by @MarcJBrooker and @ankushpd: Systems Correctness Practices at Amazon Web Services on how they use formal methods internally at AWS. One of the best articles I've read this year on formal verification and testing. I liked how this article lists various methods and how they're used to solve particular cases. Also includes references to some great papers"

"AWS published a blog post: An Aurora DSQL Story. It's less about database development and more like a love letter to Rust. DSQL's initial development was in Kotlin but they weren't happy with its performance. So two engineers who had never written Rust before rewrote a component in Rust. The code was 10x faster even though they didn't make any attempt to optimize it. They had spent years carefully tuning the Kotlin version which did 3000 TPS. The Rust one clocked 30000 TPS. Insane They wanted to extend Postgres. Instead of C they chose Rust again for memory safety reasons. For tooling reasons"
