And I want to spend a couple of minutes again reinforcing that. So if we look at that code and we were little more careful about this, what did we say to do? We said look an sorry.
内容了,我还要花几分钟,来强化下,所以,如果我们再仔细些看下代码,我们应该关注些什么?
Let's be careful here; let's do this for Firm 1 and we'll do Firm 2 in a second.
这里要稍微注意一下,我们先写公司1的然后再写公司2的
So let me expand on that very slightly, and again we did this last time but I want to do one more time. I have to be careful about how I'm actually implementing a list.
我们之前做过了一次,但还是再做一次吧,我得小心的在列表中执行,例如在这个例子中。
It used to be thought before people were very careful- we know that they do every terrible thing in the world in the Peloponnesian War.
人们谨慎行事之前曾考虑过,我们知道他们在伯罗奔尼撒战争中,做尽了世上的恶事
If I came to the office next week and decided domestic stocks were too high -I want to move that target down to 8% -in the way that I've described market timing, that would be a market timing move and we're very careful not to do that.
如果下周我上班时,认为国内股票价格偏高,我会把权重调低到8%,用我描述过的方式,这就是个市场时机选择的操作,我们一般很谨慎,并不会轻易那么做
But because we're now programming a computer at a lower level and because as we said last week, you really have to be precise and then careful to instruct this machine, this fairly dumb machine that will only do what you tell it to do very specific instructions, do we have to use a more precise syntax than just a puzzle piece might have previously allowed.
但是我们是要在电脑的低平台上编程不是吗?,那我们就要像我上周提到过的那样,一定要小心,小心,再小心地,操纵这台又聋又哑的机器,它只会根据你敲进去的,特定指令来做事,所以我们必须使用非常精细的语法,而不是模模糊糊,让人费解的概念。
On Thursday we'll do a more careful analysis and try and understand how I could have accomplished this seemingly magical task of solving an exponential problem so really quickly.
在周四的时候,我们会做进一步的分析,并且尝试理解我为什么,能如此快速的解决这种,看上去超复杂的指数型问题。
Now why do I need to be a little bit careful?
为什么我需要再小心一点呢
