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.

SICP is useful if you're a 1st of 2nd year in college- or pragmatically on a similar level of where they're at. Once you get past discrete mathematics, there is really no benefit to SICP
