The Register: “More than half of GitHub is duplicate code, researchers find” (Crista Lopes research)

An international team of eight researchers didn’t set out to measure GitHub duplication. Their original aim was to try and define the “granularity” of copying – that is, how much files changed between different clones – but along the way, they turned up a “staggering rate of file-level duplication” that made them change direction.
