They are computationally challenged, meaning, at the time they were invented, they were perfectly good sorting algorithms, there are better ones, we're going to see a much better one next time around, but this is a good way to just start thinking about how to do the algorithm, or how to do the sort.

OK. We wanted to finish up that section, we're now going to start on a new section, and I want to try and do one and a half things in the remaining time. I'm going to introduce one topic that we're going to deal with fairly quickly, and then we tackle the second topic, it's going to start today, and we're going to carry on.

I stress it in particular because I know you're all going to get into this stage; you've got a problem set due in a couple of hours, you're still writing the code, you don't want to waste time, and I'm going to use quotes on "waste time", doing those extra things to do the defensive programming, you just want to get the darn thing done.
我特别强调了这一点,因为我知道你们都会慢慢成为程序员;,你在写代码过程中造成了一系列的错误,你还在写代码,你不想浪费时间,我想把“浪费时间“用引号圈起来,浪费时间来做因为防卫性程序设计,而带来的这些额外的事情,你只想赶紧把程序写完,这不是一个好习惯,因为当你做完回头。

And it's a topic I want to pick up on today, we're going to do for the next few lectures, and it's a topic I want to spend some time on because this idea of capturing data and methods, the term we're going to use for it, but data and functions that belong to that data, things that can be used to manipulate them, is a really powerful one.
我们会在今天讲这个话题,在后面几节课还会讲这个,这是个我愿意花点时间,在上面的话题因为这是个,捕获数据和方法的思想,我们用这个术语来形容它,数据中包括了数据和函数等,能用来操作它们的东西,真的是很强大的工具,我们真正要讲的东西是,我们要学会如何把信息。
