If history is any indication 72% of the people ; in the theater have no prior programming experience; despite what you may think and despite the fact that some of you may very well be thinking, odds are I know the least about computers than anyone in here, I'm actually a little scared of my computer.
以往的经验表明,大讲堂里72%的人没有任何编程经验;,不管你们怎么想,有些人可能现在就在考虑了,奇怪的是比起在座的各位,我最不了解计算机,我甚至有点怕我的电脑。
