UNIX systems programming can be accomplished by looking at man pages and referencing kernel / user land source code.

I find something cathartic writing C applications and tools. Perhaps I should seek professional help.

Not an expert in C, but there's definitely a refreshing feel of purity about something old and "sharp", that is powerfully entrenched in the UNIX ecosystem but can also be dangerous and bite you.
