debug

關於 debug, 大師如此開示:

As soon as we started programming, we found to our surprise that it wasn’t as easy to get programs right as we had thought. Debugging had to be discovered. I can remember the exact instant when I realized that a large part of my life from then on was going to be spent in finding mistakes in my own programs.

做的時候感到很充實, 但想通後卻令人不勝唏噓啊....
