There are free tools like PDFRider that let you manipulate PDF files and do things like extracting only some pages from a PDF document & packaging them into a new PDF.

You'll see this - That's the JavaScript console used by web developers which is usually blank but Facebook inserts a warning  there to alert unsuspecting users who can become victims of a social engineering attack . As there are multiple ways (self-XSS, clickjacking, sharebaiting, phishing, bad apps, access token theft) that a non-technical Facebook users can be exploited by web scamsters, Facebook documents the ways in which victims can fall prey possibly hoping that they will bother to read it.

Though the book Exam Ref 70-534 Architecting Microsoft Azure Solutions  came after I cleared the exam, I've found the book very useful and well-written. Some of the definitions and explanations are presented very crisply. I'm compiling a list of key points from the book and online resources to serve as a glossary of sorts which I plan to review frequently. This is an embedded Microsoft Office presentation, powered by Office Online . The curriculum of the exam covers the entire breadth of Microsoft Azure Services. I'm amazed at how big & complex Azure has grown since I started working with it in 2010.
