 To get information about commits, such as the insertions, deletions, and files changed for a given day, the version control system used by Panjiva was mined. Panjiva uses git and Github to store and track changes in its source code. In order to find the total number of lines and files changed in a given day, the master git repository (the version of the code which is public and launched to production) was programmatically scraped for information. Note that the variable $lineschanged$ counts every line that was changed, whether an insertion or deletion, and is simply equal to $insertions + deletions$. The variable $fileschanged$ is the number of distinct files for which at least one line was inserted or deleted.
