Github Contributions: More than meets the eye

I have a few unemployed friends who have been searching for jobs lately and many companies are requesting links to their Github accounts, but I always found the Github “Contributions” chart to be misleading. Here’s a public screenshot of mine, for example:

It looks like I have a few days of heavy work but then forget about Github for long stretches of time. Now here’s the logged-in screenshot of my contributions chart:

You can see that I’ve been active on Github most weekdays and even occasional weekends. If the viewer doesn’t have access to the same repositories as the user does, they aren’t getting the real view of the user’s contributions. An interesting chart, but not the most accurate portrayal of a programmer’s activity.
