Ruby off the Rails: Code library yanked over license blunder, sparks chaos for half a million projects

On Wednesday, Bastien Nocera, the maintainer of a software library called shared-mime-info, informed Daniel Mendler, maintainer of a Ruby library called mimemagic, which incorporates Nocera's code, that he was shipping mimemagic under an incompatible software license.The shared-mime-info library is licensed under the GPLv2 license and mimemagic was listed as an MIT licensed project."Using a GPL file as a source makes your whole codebase a derived work, making it all GPL, so I think it's pretty important that this problem gets corrected before somebody uses it in a pure MIT codebase, or a closed-source application," wrote Nocera in an Issues post.
