You could read my columns (or at least skim them), in particular the UnixReview section, which are bite-sized chunks of topics and sample code, written towards an audience that has just finished the Llama book. The WT and LM series are a bit steeper in presumptions, but might still reveal (and cure) some interesting holes in your knowledge.
