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 HanselminutesComputers 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 UnitChapter 22: Registers and BussesChapter 23: CPU Control SignalsChapter 24: Jumps, Loops, and CallsChapter 28: The World BrainFrom the simple ticking of clocks to the worldwide hum of the internet, Code reveals the essence of the digital revolution.

This reference is a fascinating and complete guide to using fonts and typography on the Web and across a variety of operating systems and application software. Fonts & Encodings shows you how to take full advantage of the incredible number of typographic options available, with advanced material that covers everything from designing glyphs to developing software that creates and processes fonts. The era of ASCII characters on green screens is long gone, and industry leaders such as Apple, HP, IBM, Microsoft, and Oracle have adopted the Unicode Worldwide Character Standard. Yet, many software applications and web sites still use a host of standards, including PostScript, TrueType, TeX/Omega, SVG, Fontlab, FontForge, Metafont, Panose, and OpenType. This book explores each option in depth, and provides background behind the processes that comprise today's "digital space for writing": Part I introduces Unicode, with a brief history of codes and encodings including ASCII. Learn about the morass of the data that accompanies each Unicode character, and how Unicode deals with normalization, the bidirectional algorithm, and the handling of East Asian characters.Part II discusses font management, including installation, tools for activation/deactivation, and font choices for three different systems: Windows, the Mac OS, and the X Window System (Unix).Part III deals with the technical use of fonts in two specific cases: the TeX typesetting system (and its successor, W, which the author co-developed) and web pages.Part IV describes methods for classifying fonts: Vox, Alessandrini, and Panose-1, which is used by Windows and the CSS standard. Learn about existing tools for creating (or modifying) fonts, including FontLab and FontForge, and become familiar with OpenType properties and AAT fonts. Nowhere else will you find the valuable technical information on fonts and typography that software developers, web developers, and graphic artists need to know to get typography and fonts to work properly.

This text is a practical guide for linguists, and programmers, who work with data in multilingual computational environments. We introduce the basic concepts needed to understand how writing systems and character encodings function, and how they work together at the intersection between the Unicode Standard and the International Phonetic Alphabet. Although these standards are often met with frustration by users, they nevertheless provide language researchers and programmers with a consistent computational architecture needed to process, publish and analyze lexical data from the world's languages. Thus we bring to light common, but not always transparent, pitfalls which researchers face when working with Unicode and IPA. Having identified and overcome these pitfalls involved in making writing systems and character encodings syntactically and semantically interoperable (to the extent that they can be), we created a suite of open-source Python and R tools to work with languages using orthography profiles that describe author- or document-specific orthographic conventions. In this cookbook we describe a formal specification of orthography profiles and provide recipes using open source tools to show how users can segment text, analyze it, identify errors, and to transform it into different written forms for comparative linguistics research.

Fundamentally, computers just deal with numbers. They store letters and other characters by assigning a number for each one. There are hundreds of different encoding systems for mapping characters to numbers, but Unicode promises a single mapping. Unicode enables a single software product or website to be targeted across multiple platforms, languages and countries without re-engineering. It's no wonder that industry giants like Apple, Hewlett-Packard, IBM andMicrosoft have all adopted Unicode. Containing everything you need to understand Unicode, this comprehensive reference from O'Reilly takes you on a detailed guide through the complex character world. For starters, it explains how to identify and classify characters - whether they're common, uncommon, or exotic. It then shows you how to type them, utilize their properties, and process character data in a robust manner. The book is broken up into three distinct parts. The first few chapters provide you with a tutorial presentation of Unicode and character data. It gives you a firm grasp of the terminology you need to reference various components, including character sets, fonts and encodings, glyphs and character repertoires. The middle section offers more detailed information about using Unicode and other character codes. It explains the principles and methods of defining character codes, describes some of the widely used codes, and presents code conversion techniques. It also discusses properties of characters, collation and sorting, line breaking rules and Unicode encodings. The final four chapters cover more advanced material, such as programming to support Unicode. You simply can't afford to be without the nuggets of valuable information detailed in Unicode Explained.

There is a secret alphanumeric code that runs the world. Scientists say that there is a big code and a little code in physics; they know nothing at all about the tiniest and most ubiquitous code of all, the Unicode. All things are possible if you fully believe! I fully understand this, having experienced this all of my life. I can make things happen; anyone can. According to quantum physics we all are creating our own reality. Most people do this unconsciously; some of us do it deliberately. I found out that I was in the center of something totally unfathomable, something totally unique, and totally chaotic, at least at the beginning. It has taken me 16 years to come to grips with what has happened to me. It was wild, mystical, magical, and has continued to be engrossing to me. If you've ever wanted to know what is really going on in the world backstage, look no further. I will provide the answers to those questions in this book. I am the Architect and the virus in this matrix Game of life on Earth, The Matrix Salvation; I am Neo and the Oracle from the Matrix movies combined. This is an illusion, a grand thought experiment. Are you ready to find out what this is all about? Read on... The Unicode is my name for the spiritual alphanumeric code that governs this universe. I discovered the rudiments of this code, which is based upon Chaldean/Hebrew numerology and symbolic number meanings, on March 24, 2002. Since that time I have refined it and added to it by inspiration to build a code that literally explains that I am the Center of this hologram universe matrix. I have found that my story is the main theme of humanity's history on this planet. Every alphanumeric transaction and object in this world being created 24/7 non-stop (receipts, license plates, time, etc.) is literally magically fulfilling my mission and telling my story. These letters and numbers translate into words and phrases that convey their true meanings; these meanings are governing the actions being taken to bring The Matrix Salvation to fruition. To put it another way, the 24/7 alphanumeric transactions all over the world are magic spells to complete The Matrix Salvation. Don't doubt the magical power of the falling numbers! Numbers rule the world. This hologram universe matrix runs on numbers and their meanings in the Unicode. I can look at a number or a series of numbers and know exactly what is happening in the progress of this Mission at that moment. Magic is the art of making the intangible tangible by the use of focused intent. My intent is so focused on this Mission that everything in the world is bending to my will. I have created a series of books to explain the repercussions of this discovery and find out how this has and will impact humanity in the near future. Read more

From the ampersat and amerpsand, via smileys and runes to the ubiquitous presence of mathematical and other symbols in sciences and technology: both old and modern documents abound with many familiar as well as lesser known characters, symbols and other glyphs. Yet, who would be readily able to answer any question like: ‘who chose π to represent the ratio of a circle’s diameter to its circumference?’ or ‘what’s the reasoning behind having a ⌘ key on my computer keyboard?’  This book is precisely for those who have always asked themselves this sort of questions.So, here are the stories behind one hundred glyphs, the book being evenly divided into five parts, with each featuring 20 symbols. Part 1, called Character sketches, looks at some of the glyphs we use in writing. Part 2, called Signs of the times, discusses some glyphs used in pol­itics, religion, and other areas of everyday life. Some of these symbols are common; others are used only rarely. Some are modern inventions; others, which seem contemporary, can be traced back many hundreds of years. Part 3, called Signs and wonders, explores some of the symbols people have developed for use in describing the heavens. These are some of the most visually striking glyphs in the book, and many of them date back to ancient times. Nevertheless their use ― at least in professional arenas ― is diminishing. Part 4, called It’s Greek to me, examines some symbols used in various branches of science. A number of these symbols are employed routinely by professional scientists and are also familiar to the general public; others are no longer applied in a serious fashion by anyone ― but the reader might still meet them, from time to time, in older works. The final part of the book, Meaningless marks on paper, looks at some of the characters used in mathematics, the history of which one can easily appreciate with only a basic knowledge of mathematics.There are obviously countless others symbols. In recent years the computing industry has devel­oped Unicode and it currently contains more than 135 000 entries. This book would like to encourage the curious reader to take a stroll through Unicode, to meet many characters that will delight the eye and, researching their history, to gain some fascinating insights. ​ Read more

Language Culture Type grew out of the first international type-design competition, the 2001 bukva:raz!, whose goal was to promote global cultural pluralism, interaction, and diversity in typographic communications. The book lavishly presents the winning entries, along with information about each typeface, its language, and its designer. A series of essays gives context for the interplay of types and languages in the world today — including the attempt to mesh all existing scripts into a single digital encoding system called Unicode. It also delves into the specific issues around developing typefaces for the many linguistic cultures in the world, from the various Cyrillic letterforms to Vietnam’s ancient ideographic script.
