What really sets the iPhone apart from laptops and PCs is its use of onboard sensors, including those that are location-enabled. This concise book takes experienced iPhone and Mac developers on a detailed tour of iPhone and iPad hardware by explaining how these sensors work, and what they're capable of doing.

With this book, you'll build sample applications for each sensor, and learn hands-on how to take advantage of the data each sensor produces. You'll gain valuable experience that you can immediately put to work inside your own iOS applications for the iPhone, iPod touch, and...

Turn your iPhone or iPad into the hub of a distributed sensor network with the help of an Arduino microcontroller. With this concise guide, you ll learn how to connect an external sensor to an iOS device and have them talk to each other through Arduino. You ll also build an iOS application that will parse the sensor values it receives and plot the resulting measurements, all in real-time.

iOS processes data from its own onboard sensors, and now you can extend its reach with this simple, low-cost project. If you're an Objective-C programmer who likes to experiment, this book explains...

It's official: with IPv4 network addresses close to depletion, moving to IPv6 is now business critical. This concise book helps you plan for IPv6 integration by providing a high-level overview of the technical--and nontechnical--steps involved. Many of the challenges for your enterprise are on the organizational level, and solutions differ from company to company.

As technology has developed, computer hackers have become increasingly sophisticated, mastering the ability to hack into even the most impenetrable systems. The best way to secure a system is to understand the tools hackers use and know how to circumvent them. Defense against the Black Arts: How Hackers Do What They Do and How to Protect against It provides hands-on instruction to a host of techniques used to hack into a variety of systems.

Exposing hacker methodology with concrete examples, this book shows you how to outwit computer predators at their own game....

Emulation is a hybrid experimentation technique intended to bridge the gap between simulation and real-world testing. The key idea of emulation is to reproduce in real time and in a controlled manner the essential functionality of a system, so that it can interact with other real systems that can thus be evaluated. This book describes the technique of network emulation and compares it with the other experimental approaches: the scholarly analytical modeling, the popular network simulation, and the demanding real-world testing. To emphasize the practical aspects related to emulation, this...
