Certain technologies bring out everyone's hidden geek, and iPhone did the moment it was released. Even though Apple created iPhone as a closed device, tens of thousands of developers bought them with the expressed purpose of designing and running third-party software. In this clear and concise book, veteran hacker Jonathan Zdziarski - one of the original hackers of the iPhone - explains the iPhone's native environment and how you can build software for this device using its Objective-C, C, and C++ development frameworks."iPhone Open Application Development" walks you through the iPhone's proprietary development environment, offers an overview of the Objective-C language you'll use with it, and supplies background for the iPhone operating system. You also get detailed recipes and working examples for everyone's favorite iPhone features - graphics and audio programming, interfaces for adding multitouch functionality to games, the use of hardware sensors, and the device's vast user interface kit.

Many would–be software entrepreneurs with expertise in many fields attempt to turn a homegrown application—one developed for use in their own business or profession—into a commercial product. Lack of knowledge, experience, or skills often prevents the idea from ever taking shape, let alone achieving its potential. Entering a new field to start a business leaves many developers unprepared and not even fully aware it’s something they know so little about. They will also often have a job that conflicts with the time commitment required to market the program well enough for it to become a complete success.

Do you have an idea for a commercially viable software product or already have a product with the potential for dream financial rewards? Would–be software entrepreneurs must consult From Program to Product: Turning Your Code into a Saleable Product, written by software developer and entrepreneur Rocky Smolin, for an indispensable roadmap to creating a commercially successful software product. Smolin shares insights from his own experience and covers topics you may never anticipate but are vital to success, like pricing, documentation, licensing, and tracking customers.

At any given moment, somewhere in the world someone struggles with the same software design problems you have. You know you don't want to reinvent the wheel (or worse, a flat tire), so you look to Design Patterns–the lessons learned by those who've faced the same problems. With Design Patterns, you get to take advantage of the best practices and experience of others, so that you can spend your time on…something else. Something more challenging. Something more complex. Something more fun.

You want to learn about the patterns that matter–why to use them, when to use them, how to use them (and when NOT to use them). But you don't just want to see how patterns look in a book, you want to know how they look "in the wild". In their native environment. In other words, in real world applications. You also want to learn how patterns are used in the Java API, and how to exploit Java's built-in pattern support in your own code.

You want to learn the real OO design principles and why everything your boss told you about inheritance might be wrong (and what to do instead). You want to learn how those principles will help the next time you're up a creek without a design pattern.

Even the best developers have seen well-intentioned software projects fail — often because the customer kept changing requirements, and end users didn't know how to use the software you developed. Instead of surrendering to these common problems, let Head First Software Development guide you through the best practices of software development. Before you know it, those failed projects will be a thing of the past.

With its unique visually rich format, this book pulls together the hard lessons learned by expert software developers over the years. You'll gain essential information about each step of the software development lifecycle — requirements, design, coding, testing, implementing, and maintenance — and understand why and how different development processes work.

UML, the Universal Modeling Language, was the first language designed to fulfill the requirement for "universality." However, it is a software-specific language, and does not support the needs of engineers designing from the broader systems-based perspective. Therefore, SysML was created. It has been steadily gaining popularity, and many companies, especially in the heavily-regulated Defense, Automotive, Aerospace, Medical Device and Telecomms industries, are already using SysML, or are plannning to switch over to it in the near future.
