Fetching favicons with Ruby
With Ruby and Google, to be exact.
Favg is a simple gem that wraps one of Google’s S2 services and can be used to fetch and save websites’ favicons.
To fetch a favicon:
require "favg"
Favg.fetch "killingcreativity.com"
=> "\x89PNG\r\n\x1A\n\x00\x00\x00\rIHDR\x00\x00\x00\x10\x00\x00\x00\x10\b\x06\x00\x00\x00\x1F\xF3\xFFa\x00\x00\x00\x04sBIT\b\b\b\b|\bd\x88\x00\x00\x00OIDAT8\x8Dc\xFC\xFF\xFF\xFF\x7F\x06\n\x00\x13%\x9AG\r\x80\x00\x16\\\x12\x8F\x1E=b\xD8\xB7o\x1F\x03\x03\x03\x03\x83\x93\x93\x13\x83\x9C\x9C\x1Ci\x06\xEC\xDB\xB7\x8F\xE1\xF6\xED\xDBp~BB\x02Vu\xB4\xF3\x82\x93\x93\x13V6:`\x1CM\x89\x83\xC0\x00\x00g\xEB\x15\x94e\x1Er\x85\x00\x00\x00\x00IEND\xAEB`\x82"
