Meta Engineers Walk Through DotSlash on the Meta Tech Podcast
Meta software engineers Andres Suarez and Michael Bolin join Pascal Hartig (@passy) on the Meta Tech Podcast to explain how DotSlash works. DotSlash, an open source tool from Meta now available for wider use, addresses the friction of distributing binaries and toolchains to developers. Instead of checking large, platform-specific executables straight into a repository, the tool pairs a fast Rust program with a JSON manifest prefixed by a `#!` to transparently locate and run the needed binary.
The episode digs into how Meta uses DotSlash internally and how Suarez’s and Bolin’s career paths eventually led them to build and release the project.
