Linux Journal Readers' Choice
Linux Journal unleashed their annual Readers' Choice Awards the other day, and I am proud to note that Linux System Programming—my recent work on system-level Linux hacking—received an honorable mention in the category of "Favorite Linux Book." Whether you live strictly at the lowest levels or only occasionally reach outside your cozy virtual machine; whether you code in C++ or Python; whether you are wolf or neophyte, the text is both an excellent guide to systems programming and a handy reference to Linux's sparsely-documented system call API.
Disclaimer: I am Contributing Editor at LJ, but I was wholly uninvolved in the Readers' Choice Awards. Hat tip to "loyal reader" for the link.
