Relearning/Modern C

Hi /prog/,
I want to re-learn C the right way.

When I was in college I took a bunch of courses (data structures, ADTs, algorithms) but I don't think I gained a deep knowledge of C.

What are some good books or resources on modern C usage (K&R is pretty dated)?

I'd like to do some HPC later in my life and I need to start somewhere.

Maybe you should try java: http://static.springsource.org/spring/docs/2.5.x/api/org/springframework/aop/framework/AbstractSingletonProxyFactoryBean.html

Or php, which is an even better choice. Especially with Zend Framework. It is a general purpose language, with namespaces and great support for closures. Everything an enterprise enabled coder needs.
