Wrong inputs

On two occasions I have been asked, — "Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?" In one case a member of the Upper, and in the other a member of the Lower, House put this question. I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question.

What is Object Oriented Programming?

I recently gossiped again about how formal education did not properly define topics such as OOP. So here's my attempt:

In OOP, you can define your own data types, called classes. A class can consist of some data structures and some code associated with the class. A variable whose type is a class is called an object. Thus objects logically tie some data to some code. Classes can contain objects of another class (has a), or classes can inherit from other classes (is a).

Two aphorisms on the work

Today we had a course on the matter of quality. I contributed two paraphrased sayings during this. This is the first one:

The master has failed more times than the beginner has even tried.

Stephen McCranie

The second appears to be less specifically cited to one source in particular. It goes like this: Good, Fast, Cheap. Pick two.

Searching the web for this turns up the Wikipedia article on the "Project management triangle" which lists scope, cost, and time as the corners. The middle of this triangle is labeled as quality. Here's another article about it, referring to the three points with my terms.
