Yes, it’s not a typo, the example is from reel life 🙂
Remember ending of all time favourite movie Sholay?
Well the one that I had seen in childhood was about Thakur surrendering Gabbar to police. Recently I downloaded a copy from totrent for family. Today when I watched it till end, I saw Thakur kills Gabbar in the end. I was stunned to realize how the simple concept of designing loosely coupled systems existed in Bollywood 40 years ago. Coming to programming world, now everybody is focussing on programming to an interface.
Amazing to notice that Mr. Sippi kept the climax scenes programmed to have different endings, each one as real as the other, one the director’s cut and other for cinema halls.
We the developers have a lot more to learn from outside the software sysyems!
