I am glad that you found my comments useful. I use HN as my "blog" and generally include references to books/papers/articles as a pointer to further information on a topic. You will find links to lots of books if you search my comments for key phrases (eg. embedded, book etc.).

One thing i try to do is point people to lesser-known but very good and advanced books. I generally find that most HN book suggestions refer only to popular books most of which are just so-so while many great books remain unknown which is a shame. For example how many people know of Operating Systems in Depth by Thomas Doeppner? It has lots of helpful illustrations, compares concepts in both Linux/Windows implementations and is an all-round great book. I really understood the nuances of signal handling between kernel/user modes when i read it here.
