If you use an Android phone or tablet (and chances are you do), then you use Linux. Google decided to brand its embedded Linux device as Android and it makes marketing sense. If you use the "Cloud", then you use Linux. The Linux operating system runs the majority of web sites today. When I first started using Linux, the community consisted mostly of programmers and hobbyists. I don’t recall any discussion lists that focused on desktops or commercial applications. We logged onto the Internet by starting a daemon. We didn’t have dialers or web browsers like the ones available today. The vast majority of people I knew did their own system administration or were in some stage of learning. Reflecting on the time when we estimated that 30,000 Linux users existed on the planet, I’m amazed at how many people use Linux today and haven’t the slightest idea how to write a configuration file. Linux forums seem to be filled with people asking how to get CUPS or Samba to work. On mailing lists, people hold detailed discussions on the technical details of projects like Postfix, JBoss, and Monit. Many people still itch to learn the extensive capabilities of Linux as an application platform. If you use Linux and want to take the next step from a power user to an administrator, this book will help you make the transition. We wrote this book with you in mind.
