PDF Hacks
by Sid Steward

PDF–to most of the world it stands for that rather tiresome format used for documents downloaded from the web. Slow to load and slower to print, hopelessly unsearchable, and all but impossible to cut and paste from, the Portable Document Format doesn’t inspire much affection in the average user. But PDFs done right is another story. Those who know the ins and outs of this format know that it can be much more than electronic paper. Flexible, compact, interactive, and even searchable, PDF is the ideal way to present content across multiple platforms.

PDF Hacks unveils the true promise of Portable Document Format, going way beyond the usual PDF as paged output mechanism. PDF expert Sid Steward draws from his years of analyzing, extending, authoring, and embellishing PDF documents to present 100 clever hacks–tools, tips, quick-and-dirty or not-so-obvious solutions to common problems.

PDF Hacks will show you how to create PDF documents that are far more powerful than simple representations of paper pages. The hacks in the book cover the full range of PDF functionality, from the simple to the more complex, including generating, manipulating, annotating, and consuming PDF information. You’ll learn how to manage content in PDF, navigate it, and reuse it as necessary. Far more than another guide to Adobe Acrobat, the book covers a variety of readily available tools for generating, deploying, and editing PDF.

The little-known tips and tricks in this book are ideal for anyone who works with PDF on a regular basis, including web developers, pre-press users, forms creators, and those who generate PDF for distribution. Whether you want to fine-tune and debug your existing PDF documents or explore the full potential the format offers, PDF Hacks will turn you into a PDF power user.

The book will contain an introduction, 8 sections and a conclusion.  Each section will begin by describing an overarching principle of the lifehacker, and then segue into concrete applications of that guideline offering 103 useful life hacks for getting things done faster online and off.  

Each individual software-related hack will be a detailed, step-by-step how-to for setting up and using the solution.  All software-related hacks will employ freely-available applications with a focus on Windows users. Mac equivalents will be included.  Wherever possible, free web applications and platform-agnostic software will be used. Most but not all hacks will be software-related.  Non-software related hacks will be written in a helpful, suggestive, conversational tone and include suggestions for as many life circumstances as possible. Each hack will include detailed screenshots and sidebars with additional tips, case studies and quotes throughout. Sample:

Method 2: Block the time-wasting sites entirely:

Alternately, you can make it hard to visit time-sucking sites, which forces yourself to stop and think, “Do I really have time to do this right now?” Set your computer to block those URLs and make yourself unblock them each time you want to visit. One way to do this is to tell your computer that these sites live on your hard drive – which obviously they don’t – and get a “Server not found” error when your fingers impulsively type out that tempting URL. Here’s how:   

Using Notepad or some other text editor, open the file named “hosts”, which is located in the following directory:

  • Windows 98\ME = C:\WINDOWS

Add the following on its own line in the hosts file, using the sites that apply to you:

  • Save and quit.
