Wasmer: a Python library for executing WebAssembly binaries. This is a really interesting new tool: “pip install wasmer” and now you can load code that has been compiled to WebAssembly and call those functions directly from Python. It’s built on top of the wasmer universal WebAssembly runtime, written over just the past year in Rust by a team lead by Syrus Akbary, the author of the Graphene GraphQL library for Python. # 6:04 pm

ripgrep is faster than {grep, ag, git grep, ucg, pt, sift} (via) Andrew Gallant’s post from September 2016 introducing ripgrep, the command-line grep tool he wrote using Rust (on top of the Rust regular expression library also written by Andrew). ripgrep is a beautifully designed CLI interface and is crazy fast, and this post describes how it gets its performance in a huge amount of detail, right down to comparing the different algorithmic approaches used by other similar tools. I recently learned that ripgrep ships as part of VS Code, which is why VS Code’s search-across-project feature is so fast. In fact, if you dig around in the OS X package you can find the rg binary already installed on your mac: find /Applications/Visual* | grep bin/rg # 5:52 pm
