"Enlightenment Now: The Case for Reason, Science, Humanism, and Progress"
Is the world really falling apart? Is the ideal of progress obsolete? Cognitive scientist and public intellectual Steven Pinker urges us to step back from the gory headlines and prophecies of doom, and instead, follow the data: In seventy-five jaw-dropping graphs, Pinker shows that life, health, prosperity, safety, peace, knowledge, and happiness are on the rise.

From the Back Cover
Peeling Apple's Operating Systems
System-level developers, kernel hackers, and intrigued Apple-lytes, take heed: This book lets you explore the nooks and crannies of Mac OS X and iOS, delving into the architecture of both systems, and picking up where the frameworks (and documentation) leave off. It offers clear, detailed explanation of the inner workings of Apple's systems, including proprietary APIs, most of which are documented for the first time.
As you traverse the architecture, moving from user to kernel mode, each layer and component is unraveled with annotated code samples and hands-on experiments, comparing and contrasting its implementation in both OSes. Topics include:
- The boot process: Mac's EFI, iOS's iBoot, and kernel startup
- Processes, threads, and virtual memory management
- Debugging and profiling, using DTrace, ptrace, and hidden system calls
- The system level APIs: POSIX calls, Mach traps, and OS X/iOS proprietary
- File system architecture, including VFS and HFS+
- Network architecture: from sockets to interfaces, and network drivers
- Kernel extensions, drivers, and a discussion of I/O Kit architecture
- Security features, Mandatory Access Control, and iOS jail
The companion web site (http://www.newosxbook.com) includes sample programs, freely downloadable tools, updated references, and bonus additions.

If you are a regular user, this book is a waste of time, but if you work on hardware, software or you want to learn the inner mechanics of this operating system, this book will guide you trough the ton of info that nobody tells you about.
I have serious problems to understand the official docs from Apple; when I am able to find what I need of course...and this book resolve both issues. It will guide you trough the various applications running on the system, telling you what they do, then you will get your feet wet working on terminal, getting info about the kernel, Mach and the underlying structure of the OS, where each specific layer is explained.
If you do kernel programming work, this book is a bible. IF you are a beginner, this book will tell you what is going on when you run your app on iOS or OSX, using Xcode, or how to manipulate some inner mechanism of the system.
Do yourself a favor and read this book; it is for Mac/iOS developers, the equivalent of what the K&R book is, for C programmers.
