The release of the new Computable Document Format (CDF) has been reported by some as ringing the death-knell of PDF. In this article, Dan Shea talks about the strengths, obstacles and possibilities for the new "PDF-killer".
Following the addition of sandbox technology to Adobe's flagship product, people (including we at Planet PDF) have been keen to nail down the practical implications of the move. Sure, it makes PDF viewing safer, but how will it affect my elegant PDF document workflow? In this article, Dan Shea takes a look at some of the finer points of "Protected View", Acrobat's new bodyguard.
Unfortunately, exploiting security vulnerabilities in Adobe's PDF products has become something of a growth industry. In response, Adobe has released major security updates to Reader (last November), Acrobat (two weeks ago) and their corresponding web browser plug-ins. These updates integrate "sandboxes" to isolate the software from system resources.
If a PDF document has Reader Extensions enabled, then certain features that are normally only available in Adobe Acrobat are also available in the free Adobe PDF Reader. These features include saving (form) data locally and applying digital signatures. Frank Rem takes a look "under the hood" to gain a better understanding of how Reader Extensions works.
PDF files are generally judged on how they appear. The problem is that a well-crafted PDF (basically, one that works) and a horrible PDF (one that doesn't) can look identical onscreen. Mark Stephens from IDRsolutions explains how to spot the difference and why it matters.
PDF files come in all shapes and sizes. They vary from relatively simple to mind-numbingly complex. PDFs can also differ in their degree of conformance to the PDF specification -- the bad ones are often called malformed PDFs. In this article, Rowan Hanna discusses the pros and cons of Adobe Acrobat automatically repairing these malformed PDF files.
In the final part of this two part series, Jim King, a PDF Architect and Senior Principle Scientist at Adobe, takes a closer look at PDF forms as he discusses the editablility and resuse of content found in PDF files and highlights the fact that despite some people's misperceptions, PDF content is only frozen if you choose it to be.

What exactly is a "conforming PDF reader" and what does it have to do with PDF 2.0? Olaf Druemmer, chairman of the PDF/A Competence Center, explains all in this in-depth article.
When you set up password security for a PDF document you are first asked to select an encryption level for the PDF file. If you're a computer geek you may immediately understand what this means, but if you're not you may be puzzled. What does encryption mean and how does it affect your security choices?
