`When there were no computers programming was no problem. When we had a few weak computers, it became a mild problem. Now that we have gigantic computers, programming is a gigantic problem."---Edsger Dijkstra

Advice to computer Science Student
Computer Science is fascinating field; but it is also a very time consuming discipline to pursue. You can make it only when you have made enough effort on it. Learn ethically and responsibly. I would like to share some quotes with my dear students. (Send me good quotes if you have any, I will add them here!)

“Twenty years from now you will be more disappointed by the things you didn't do than by the ones you did. So throw off the bowlines, Sail away from the safe harbor. Catch the tradewinds in your sails. EXPLORE. DREAM. DISCOVER.” (Twain)
"Choose a job you love, and you will never have to work a day in your life." – Confucius
“Choose a major you love, you will enjoy learning with passion” – anonymous
If you're not failing every now and again, it's a sign you're not doing anything very innovative.- W. Allen
If you understand what you're doing, you're not learning anything.- Anonymous

· Y = X*96 can be optimized to：Y = X* 64 + X * 32 ->Y = X<<6 + X <<5

· tar -xjvf something.tar.bz2

· “2>&1″ means “redirect standard error (2) to the same place as standard outout (1.)

· scanf("%[^\t\n]",string);
