Joel Spolsky and the Best Essays of 2003/2004
Joel Spolsky is working on a new book, rather than spread more of his own wisdoms, if you don’t read his site then you should!, he is compiling and editing a list of the best software essays published either online or on dead tree.
While it is probably going to be quite a while before the book becomes available you can currently view the list of nominations and, in most cases, read them online.
