Brian Kernighan
Brian Wilson Kernighan is a Canadian computer scientist who worked at Bell Labs alongside Unix creators Ken Thompson and Dennis Ritchie and contributed to the development of Unix. He is also coauthor of the AWK and AMPL programming languages. The "K" of K&R C and the "K" in AWK both stand for "Kernighan". Since 2000 Brian Kernighan has been a Professor at the Computer Science Department of Princeton University, where he is also the Undergraduate Department Representative...

C is a razor-sharp tool, with which one can create an elegant and efficient program or a bloody mess.
The most effective debugging tool is still careful thought, coupled with judiciously placed print statements.
90% of the functionality delivered now is better than 100% delivered never.
Controlling complexity is the essence of computer programming.
Do what you think is interesting, do something that you think is fun and worthwhile, because otherwise you won't do it well anyway.
Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it.
Unix has, I think for many years, had a reputation as being difficult to learn and incomplete. Difficult to learn means that the set of shared conventions, and things that are assumed about the way it works, and the basic mechanisms, are just different from what they are in other systems.
Programming language is very specific to instructing a computer to do a particular structure of a sequence. It's the very way you tell the machine what you want it to do.
No matter what, the way to learn to program is to write code and rewrite it and see it used and rewrite again. Reading other people's code is invaluable as well.
No matter how non-technical your life and work, you're going to have to interact with technology and technical people. If you know something about how devices and systems operate, it's a big advantage.
If you don't understand viruses, phishing, and similar threats, you become more susceptible to them. If you don't know how social networks leak information that you thought was private, you're likely to reveal much more than you realize.
I want students to understand specific technologies, but the real goal is that they should be able to reason about how systems work and be intelligently skeptical about technology so that, when they're running the world in a few years, they'll do a good job.
I seem to get totally wrapped up in teaching and working with students during the school year. During the summer, I try to spend time in the real world, writing code for therapy and perhaps for some useful purpose.
Even though most people won't be directly involved with programming, everyone is affected by computers, so an educated person should have a good understanding of how computer hardware, software, and networks operate.
