The only way to learn a new programming language is by writing programs in it.

Unix has retarded OS research by 10 years and linux has retarded it by 20.

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.

One of the obvious things that went wrong with Multics as a commercial success was just that it was sort of over-engineered in a sense. There was just too much in it.

C++ and Java, say, are presumably growing faster than plain C, but I bet C will still be around.

I've done a reasonable amount of travelling, which I enjoyed, but not for too long at a time.

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