Rails just keeps on changing. Rails 2, released in 2008, brings hundreds of improvements over Rails 1, including new support for RESTful applications, new generator options, and more. But of course all these changes mean a new edition of this definitive book: presenting Agile Web Development with Rails, 3rd Edition.

You can buy the combo pack of the third edition now. That gets you the new PDF immediately, fresh versions of the PDF as it is updated, and the final paper book when it’s ready. But if you need a paper book right now, we have a special offer. While stocks last, we’re selling the paper version of the second edition at half price.

And, if you bought the second edition book or PDF from us after March 9, 2008, you qualify for a free update to this edition. Visit your home page to pick up the coupon.

Android is a new software toolkit for mobile phones, created by Google and the Open Handset Alliance. In a few years, it’s expected to be found inside millions of cell phones and other mobile devices, making Android a major platform for application developers. That could be your own program running on all those devices.

Getting started developing with Android is easy. You don’t even need access to an Android phone, just a computer where you can install the Android SDK and the phone emulator that comes with it. Within minutes, Hello, Android will get you creating your first working application: Android’s version of “Hello, World.”

If you’re a busy developer who’d rather be coding than reading about coding, this book is for you. See the book’s home page for details. Now available in Beta.
