"He is at 50 or below in most surveys, and that is mainly because of the economy, which continues to be stubbornly weak, the unemployment rate is very high and still in double-digits, and as a consequence Obama does not have much margin for error,".

Number one, the basic structure is that you have a pointer and it points over to a pointee, but the pointer and pointee are separate and the common error is to set up a pointer but to forget to give it a pointee.
第一,基本结构是,你有一个,指向数据的指针,但是那个指针和数据,是分开的,通常错误是声明了一个指针,但是没有指向一个数据。
- But there's one potential gotcha here -- and this is where you have to be kind -- of piecing together the little clues along the way -- what have I done that's interesting here that had I not, I would have had a mathematical error?
但是这里有一个可能性-,这就是你需要把,一些线索拼凑在一起-,我这里所做的是很有趣的,如果我不这样做,我可能已经犯了个数学错误?
And the 0.0016 is greater than what I would have as experimental error, so your theory is wrong. Bohr says oh, yeah?
。0016比,我检测出来的错误大得多,所以你的理论是错的,波尔说,哦,是吗?
I'm much better having an exception get handled at the time of input than to let that prop -- that value rather propagate through a whole bunch of code until eventually it hits an error 17 calls later, and you have no clue where it came from.
不是我期望的格式,这时我最好有一个异常处理,而不是让其传下去,这个值传到代码的整个分支,最终会导致一个错误17调用的发生,并且你不知道这个错误是哪里来的。
Second, it shows that it-- it weakens to some extent how much faith we can have in studies that link diet to health because of this error that gets introduced.
第二,表明了这在某种程度上消弱了,我们在研究饮食与健康之间联系时的信心,因为误差的出现
yeah I run this, yeah, I have a syntax error, yes indeed, because I forgot to comment that one out, all right, and cue, we'll try it again.
运行下,一个语法错误,确实是,因为我忘了把这里注释上了,好,让我们再来试试。
Let's hope that all the changes I mad have not introduced a syntax error.
希望我要做的所有这些变化,不会有什么句法错误。
It finds one syntax error at a time, so you have to be a little patient to do it, but you can check that the syntax is right.
它一次会找到一个语法错误,所以你们必须要有点耐心,但是你们可以检查出语法是否正确。
We have an error somewhere.
如果进行数学计算对的话。
And this, in my mind, should have been an error.
这个地方我认为应该是一个错误。
Notice if I'm going to have two different sub problems I need to have two base cases here to catch this. And if I only had one it would error out. And as a consequence, I can go off and ask about rabbits. Let's see.
我需要定义两个基础事件来处理它,如果我只有一个基础事件的话就会产生错误,这样我就能够知道到底有多少只兔子了,让我们来看看,在第12个月末,没那么简单,在第二年末兔子就很多了。
Way back in nineteen-eighty-two, we did a study on this, and then I'm going to show you some similar studies that have been done in subsequent years to show you how much the error is.
回到1982年,我们做了一个这样的实验,你们将看到一些类似的实验,是在随后几年中做的,向你们证明误差有多大
I spotted an error here, I could have spotted it by running it on different test sets, and using prints things, another way of doing it, but this idea of at least simulating it on simple examples lets you check a couple of important questions.
操作么?我在这里发现了一个错误,我也可以通过运行不同的测试集,或者运用print声明来发现这个错误,但是至少应该用简单的例子来手工模拟下,代码的思想可以让你,对一些很重要的问题进行检验。
