What every programmer should know about memory
Ulrich Drepper works for Red Hat, is the lead contributor and maintainer of glibc, telling you this I don’t need to comment how talented he is. Last year he gave a talk in Red Hat Summit in Nashville about CPU Caches, in his opinion the time for the talk was not enough to transfer all his thoughts about the subject, after this he worked around six months on a document titled What every programmer should know about memory, 100 pages of pure high quality knowledge, Drepper released it in PDF for free.
