The classic guide to how computers work, updated with new chapters and interactive graphics "For me, Code was a revelation. It was the first book about programming that spoke to me. It started with a story, and it built up, layer by layer, analogy by analogy, until I understood not just the Code, but the System. Code is a book that is as much about Systems Thinking and abstractions as it is about code and programming. Code teaches us how many unseen layers there are between the computer systems that we as users look at every day and the magical silicon rocks that we infused with lightning and taught to think." - Scott Hanselman, Partner Program Director, Microsoft, and host of Hanselminutes Computers are everywhere, most obviously in our laptops and smartphones, but also our cars, televisions, microwave ovens, alarm clocks, robot vacuum cleaners, and other smart appliances. Have you ever wondered what goes on inside these devices to make our lives easier but occasionally more infuriating? For more than 20 years, readers have delighted in Charles Petzold's illuminating story of the secret inner life of computers, and now he has revised it for this new age of computing. Cleverly illustrated and easy to understand, this is the book that cracks the mystery. You'll discover what flashlights, black cats, seesaws, and the ride of Paul Revere can teach you about computing, and how human ingenuity and our compulsion to communicate have shaped every electronic device we use. This new expanded edition explores more deeply the bit-by-bit and gate-by-gate construction of the heart of every smart device, the central processing unit that combines the simplest of basic operations to perform the most complex of feats. Petzold's companion website, CodeHiddenLanguage.com, uses animated graphics of key circuits in the book to make computers even easier to comprehend. In addition to substantially revised and updated content, new chapters include: Chapter 18: Let's Build a Clock! Chapter 21: The Arithmetic Logic Unit Chapter 22: Registers and Busses Chapter 23: CPU Control Signals Chapter 24: Jumps, Loops, and Calls Chapter 28: The World Brain From the simple ticking of clocks to the worldwide hum of the internet, Code reveals the essence of the digital revolution.

From the dots and dashes of Morse code to the 0s and 1s of computer programming, "Code" describes the ingenious ways humans have adapted language systems--code--to invent the machinery of the modern age. Petzold uses everyday household objects and readily recognizable codes such as Braille and Morse to build a context for understanding how computers work.

Reimagined for full-screen and touch-optimized apps, Windows 8 provides a platform for reaching new users in new ways. In response, programming legend Charles Petzold is rewriting his classic Programming Windows—one of the most popular programming books of all time—to show developers how to use existing skills and tools to build Windows 8 apps. Programming Windows, Sixth Edition focuses on creating Windows 8 apps accessing the Windows Runtime with XAML and C#. The book also provides C++ code samples. The Sixth Edition is organized in two parts: Part I, “Elementals,” begins with the interrelationship between code and XAML, basic event handling, dynamic layout, controls, templates, asynchronous processing, the application bar, control customization, and collections. You should emerge from Part I ready to create sophisticated page-oriented collection-based user interfaces using the powerful ListView and GridView controls. Part II, “Specialties,” explores topics you might not need for every program but are essential to a well-rounded education in Windows 8. These include multitouch, bitmap graphics, interfacing with share and search facilities, printing, working with the sensors (GPS and orientation), text, obtaining input from the stylus (including handwriting recognition), accessing web services, calling Win32 and DirectX functions, and bringing your application to the Windows 8 app store.

“Look it up in Petzold” remains the last word on Windows development. In this .NET-ready Windows programming guide, the best-selling author shows you how to get the most out of Windows Forms—the next-generation Windows programming class library.

Written by programming legend Charles Petzold and created jointly by Microsoft Press and Xamarin Inc., this Preview Edition ebook is about writing applications for Xamarin.Forms, the new mobile development platform for iOS, Android, and Windows Phone unveiled by Xamarin in May 2014. Xamarin.Forms lets you write shared user-interface code in C# and XAML (the eXtensible Application Markup Language) that maps to native controls on these three platforms. (The final edition of this ebook will be published in the spring of 2015.) This ebook is for C# programmers who want to write applications for the three most popular mobile platforms—iOS, Android, and Windows Phone—with a single code base. Xamarin.Forms also has applicability for those programmers who want eventually to use C# and the Xamarin.iOS and Xamarin.Android libraries to target the native application programming interfaces (APIs) of these platforms. Xamarin.Forms can be a big help in getting started with these platforms or in constructing a prototype or proof-of-concept application. This ebook assumes that you know C# and have some familiarity with the use of the .NET Framework. However, when it describes some C# and .NET features that might be somewhat new to recent C# programmers, the ebook adopts a somewhat slower pace. In particular, the introduction of the async keyword and await operator in Chapter 3 follows a discussion that shows how to do asynchronous programming using traditional callback methods.
