“You can’t prove anything about a program written in C or FORTRAN. It’s really just Peek and Poke with some syntactic sugar.”

I just don’t like to lose what’s in the window.

Just about every computer on the market today runs Unix, except the Mac and nobody cares about it.

A bomb is blown up only once-but one bot can become many, and quickly get out of control.

Although humankind inherently “desires to know”, if open access to, and unlimited development of, knowledge henceforth puts us all in clear danger of extinction, then common sense demands that we re-examine our reverence for knowledge.

Operating systems are like underwear – nobody really wants to look at them.

I got tired of people complaining that it was too hard to use UNIX because the editor was too complicated.

What’s your personal computer, anyways? Your personal computer should be something that’s always on your person.

The problem is that those few programmers who crank out code aren’t interested in maintaining it.

Systems are going to get a lot more sophisticated.

You can drive a car by looking in the rear view mirror as long as nothing is ahead of you. Not enough software professionals are engaged in forward thinking.

Take responsibility for the things you build and invent.

Most of the bright people don’t work for you – no matter who you are.

Bitmap display is media compatible with dot matrix or laser printers.

I think one of the interesting things is that vi is really a mode-based editor.

Today scientists, technologists, businessmen, engineers don’t have any personal responsibility for the consequences of their actions.

I started to write a new editor not too long ago and had it about half done after two days.

First of all, you’ve got to have a vision of ‘What kind of program do I want to have?’ Then you’ve got to have a plan to implement it. Then you’ve got to set the example that you want, develop the principles and values that are important, and get people to buy into it.

When I talk about a successful program, define that. It’s not just winning the national championship every year because nobody can do that.

If you look at the history of Notre Dame, if you hire a coach who’s been successful at another college program, they’re going to be ultra successful at Notre Dame because the talent will always be there.

We certainly don’t want them to do anything that’s going to affect themselves in an adverse way or affect our program, our university, or our team in an adverse way.

I’m proud to be part of the Dr. Pepper Scholarship Giveaway. It’s a great program that gives me the chance to brighten the day for some lucky college students with free tuition.

They told me my services were no longer desired because they wanted to put in a youth program as an advance way of keeping the club going. I’ll never make the mistake of being seventy again.

“Toward what end, toward what end?”- but do not ask it too often lest you pass up the fun of programming for the constipation of bittersweet philosophy.

There are two ways to write error-free programs; only the third one works.
