I fix things now and then, more often tweak HTML and make scripts to do things.

It seems certain that much of the success of Unix follows from the readability, modifiability, and portability of its software.

C was already implemented on several quite different machines and OSs, Unix was already being distributed on the PDP-11, but the portability of the whole system was new

I listen to mostly-classical music, but mostly by radio - I'm not an audiophile.

UNIX is basically a simple operating system, but you have to be a genius to understand the simplicity.

My work was fairly theoretical. It was in recursive function theory. And in particular, hierarchies of functions in terms of computational complexity. I got involved in real computers and programming mainly by being - well, I was interested even as I came to graduate school.

The kind of programming that C provides will probably remain similar absolutely or slowly decline in usage, but relatively, JavaScript or its variants, or XML, will continue to become more central.
