Comedian Jerry Seinfeld once revealed the secret to honing a craft: practice every single day, then mark a calendar with an 'X' and never break the rapidly growing chain. Many have taken the advice to heart over the years — even GitHub. Wired notes that the project development site recently added a calendar inspired by Seinfeld’s famous mantra to its project pages. Some have belittled the update, saying that sheer volume isn’t worthwhile, while others have passed it off as simple gamification. It may not be popular with seasoned coders, but it should prove to be a useful tool for those who need some extra motivation.
