Commits per weekday and hour

In ASF on 2009-06-04 by Jukka Zitting

The punchcard graphs at Github are a nice way to quickly detect the rough geographical distribution (or nighttime coding habits) of the key contributors of an open source project. Here’s a few selected examples from the ASF.

Apache HTTP Server

  1. Hi Jukka,

    I prefer http://svnsearch.org/svnsearch/repos/ASF/search which gives you a lot of information about each Apache project. The schema are easier to read, IMO

  2. I think the jackrabbit graph is spot on. Being in Australia, I can see the same level of activity on the mailing lists; it’s completely silent during the day, until about five in the afternoon, when the European guys come on-line.

  3. It would be nice… if you could tell what timezone the punched cards were for. It seems needlessly inscrutable.

    Hilariously, one developer created a project with a single commit just to find out what the timezone of these graphs is supposed to be.
