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.

Sometimes when you fill a vacuum, it still sucks.

At least for the people who send me mail about a new language that they're designing, the general advice is: do it to learn about how to write a compiler

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

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

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.

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.
