Kernel development can be a daunting task and is very different from programming traditional user
applications. The kernel environment is more volatile and complex. Extraordinary care must be taken to
ensure that kernel code is free of bugs because any issue may have serious consequences to the stability,
security, and performance of the system. This book covers the fundamentals necessary to begin
programming in the kernel. We cover kernel development from a theoretical and practical point of view.
We cover concepts fundamental to kernel development such as virtual memory and synchronization, as
well as more practical knowledge. The book primarily focuses on Mac OS X, however the XNU kernel is
also used by iOS, and hence the theoretical material in this book will also apply to it. By far the most
common reason for doing development within the kernel’s execution environment is to implement a
device driver for controlling internal or external hardware devices. Because of this, much of the focus of
this book is centred on the development of device drivers. The primary framework for device driver
development in the XNU kernel is I/O Kit, which we cover extensively. As theory becomes boring quickly
we have provided working code samples which you can play with to learn more or use as a starting point
for your own drivers.
We hope you have as much fun reading this book as we have enjoyed writing it.
The book was written for anyone interested in Apple’s iOS and Mac OS X operating systems, with a focus
on practical kernel development, especially driver devel. Regardless of whether you are a hobbyist,
student, or professional engineer, we hope to provide you with material of interest. While the focus is on
kernel programming and development, we will cover many theoretical aspects of OS technology and
provide a detailed overview of the OS X and iOS kernel environments. The aim of the book is to provide
the knowledge necessary to start developing your own kernel extensions and drivers. We will focus in
particular on the I/O Kit framework for writing device drivers and extensions, but we will also cover
general knowledge that will give you a deeper understanding of how I/O Kit interacts with the OS. If you
are mainly interested in developing OS X or iOS user applications, this book may not be for you. We will
not cover Cocoa or any other framework used for developing end-user applications. This book covers
kernel-programming topics such as driver and kernel extension development on Apple’s OS X and iOS
Some knowledge of operating system internals will be useful in understanding the concepts
discussed in this book. Having completed an introductory computer science or engineering course will
be a helpful starting point. Additionally, knowledge of at least one programming language will be
required in order to understand examples throughout the book. Since we focus on I/O Kit, which is
written in a subset of C++ called Embedded C++, it would be highly beneficial to have some experience
with C++ (or at least C) to make the most of this book. The book does not cover general programming
topics or theory. We will briefly cover some fundamentals of OS theory to provide a context for further
Data Access Patterns: Database Interactions in Object-Oriented Applications
Efficient, high-quality data access code is crucial to the performance and usability of virtually any enterprise application-and there's no better way to improve an existing system than to optimize its data access code.

MCSE Windows 2000 Network Infrastructure Exam Cram 2 (Exam Cram 70-216) This exam - one of four MCSE 2000 core exams - measures the ability to install, manage, monitor, configure, and troubleshoot DNS, DHCP, Remote Access, network protocols, IP routing, and WINS in a Windows 2000 network. This book is not intended to teach new material. Instead it assumes that you have a solid foundation of knowledge but can use a...
After Effects Expressions Expressions are tools. Just as you use the Rotation tool and the Pen tool, you can use Expressions to control animation and composition in After Effects (AE).
Whereas you use most tools by clicking on their icons (e.g., the pointer or the pen) and clicking or dragging with the mouse, you use Expressions by typing commands on the...

The Oxford Handbook of Philosophy of Time (Oxford Handbooks)
As the study of time has flourished in the physical and human sciences, the philosophy of time has come into its own as a lively and diverse area of academic research. Philosophers investigate not just the metaphysics of time, and our experience and representation of time, but the role of time in ethics and action, and philosophical issues in...
