Why Elixir (2014)

Parsing the .DS_Store File Format (2018)

About two years ago I came across a .DS_Store file and wanted to extract its information (e.g. file names). After researching the file format and its security implications, as well as writing a parser for it, I would like to share my (limited) knowledge and the parser in Go / Python with the world.
