Submission + - Dropbox open sources DivANS: a compression algorithm in Rust compiled to WASM

Submitted by danielrh on Tuesday June 19, 2018 @06:41PM

danielrh writes: DivANS is a new compression algorithm developed at Dropbox that can be denser than Brotli, 7zip or zstd at the cost of compression and decompression speed.
The code uses some of the new vector intrinsics in Rust and is multithreaded. It has a demo running in the browser.
One of the new ideas is that it has an Intermediate Representation, like a compiler, and that lets developers mashup different compression algorithms and build compression optimizers that run over the IR. The project is looking for community involvement and experimentation.
