And this is a little different from what happened ten or so years ago, but the so-called Y2K problem was essentially the result of programmers not really having the foresight to realize, "Maybe we shouldn't use so few bits or so few digits to represent a year because eventually this will be a problem."

这个跟10年前发生的事情有点不一样,那个所谓的“Y2K“问题,本质上的结果是,程序员没有真实地预见和认识到，“可能我们没必要用到这些位数或数字,来表示一年，但是最终这个将会,是个问题“

If we need a 7, this is the ones column, the twos, fours, eights, so here are our columns and this was our decimal system a moment ago, and I wanna express the number 7 and the only digits 0 I now have access to are zero and one, whereas, in decimal, dec meaning 10.

如果你需要7，这是一位，二位，四位，八位，这是位数,刚才说的十进制的位数，我想表达7而且,只能采用数字1与，在十进制中，dec意思是十。
