Bus Number – The GitHub plugin my coworkers asked me not to write
. This blog post was written together with <mclare>, who made coooool visualizations like the picture at the end of the post! What’s a Bus Factor or Truck Factor? According to wikipedia: The “bus factor” is the minimum number of team members that have to suddenly disappear from a project before the project stalls due to lack of knowledgeable or competent personnel.
I remembered reading about Truck Number on the original wiki, so I thought it’d be fun to write a github enterprise plugin that calculates who you can’t afford to fire. Last week I mentioned this blog post idea to mclare, and she said we should try to reproduce the results and see if the truck factor has improved in the past ten years. Without the linguist plugin to filter out documentation and third party libraries, we got a truck factor of twelve for the Linux kernel repository.
