Here's a more recent blog post: [1] and a published paper on arxiv: [2], describing the latest version of the algorithm which is implemented in fast_float C++ library [3]. Coincidentally, I've participated in this as well recently by implementing the algorithm in Rust (fast-float crate, see [4] for the source and benchmarks). It is insanely fast (easily over 1GB/s on an m1 machine) and beats all of the existing float parsers I'm aware of by a large margin, at least on the datasets we've tested it on.
