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.

I can't recall any difficulty in making the C language definition completely open - any discussion on the matter tended to mention languages whose inventors tried to keep tight control, and consequent ill fate

C is declining somewhat in usage compared to C++, and maybe Java, but perhaps even more compared to higher-level scripting languages. It's still fairly strong for the basic system-type things.

C is quirky, flawed, and an enormous success.

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

For books, I don't read much fiction, but like travel essays and good pop-science.

Pretty much everything on the web uses those two things: C and UNIX.
