Diving into Unix Internals

[abdik at rodan.acs.syr.edu]

Hello  Net-users;

I need advice in finding a good project topic for someone like me who would
like to learn Unix Internals on his own.
I have good experience in C++ and in using Unix as a user, but would like 
to work deep into Unix just for the fun of it.

Any help ?
