I had posted the same link on HN yesterday but had wrongly added the title of "Why pride of being hacker is bad". Which i realized later so had to delete it.The real title should have been "Arrogance of being a Hacker"
Before fellow HNers take offense, it's better we give it some thought and realize how something simple (yet so hard) can make much difference in not just in our own life but also for others.
