Rust is fast at runtime — but not so much at compile time. That’s hardly news to anyone who's worked on a serious Rust codebase. There's a whole genre of blog posts dedicated to shaving seconds off cargo build . At Feldera, we let users write SQL to define tables and views. Under the hood, we compile that SQL into Rust code — which is then compiled with rustc to a single binary that incrementally maintains all views as new data streams into tables. We’ve already pulled a lot of tricks in the p

A TypeScript-types-only WebAssembly runtime This is a WebAssembly runtime implemented purely in TypeScript types. The basic idea is that you can turn C code (or just straight WebAssembly) into a TypeScript type (as in, with no JavaScript runtime code) that will compile the instructions and return a result. It can run Doom This engine was built to service a project that aimed to demonstrate why Doom can't run in TypeScript types. Well. The funny thing is.. It can. There's a video about it on t
