A language that doesn't affect the way you think about programming is not worth knowing.
To understand a program, you must become both the machine and the program.
You think you KNOW when you learn, are more sure when you can write, even more when you can teach, but certain when you can program.
I think that it's extraordinarily important that we in computer science keep fun in computing. When it started out, it was an awful lot of fun. Of course, the paying customers got shafted every now and then, and after a while we began to take their complaints seriously. We began to feel as if we really were responsible for the successful, error-free perfect use of these machines. I don't think we are. I think we're responsible for stretching them, setting them off in new directions, and keeping fun in the house. I hope the field of computer science never loses its sense of fun.
It goes against the grain of modern education to teach children to program. What fun is there in making plans, acquiring discipline in organizing thoughts, devoting attention to detail and learning to be self-critical?
A good programming language is a conceptual universe for thinking about programming.
I think it is inevitable that people program poorly. Training will not substantially help matters. We have to learn to live with it.
Optimization hinders evolution.
Any noun can be verbed.
