Foolish Assumptions

Foolish Assumptions

My job in writing this book is to make using Ubuntu Linux as easy as possible. To that end, it's a good idea to convey some of my assumptions about my readers. I assume that you

• Are curious about Linux in general and want to see what it's about.

  Great! That's what this book is all about. Sure, it's oriented around learning the Ubuntu Linux distribution, but most of what you read here is applicable to any version of Linux.

• Want an alternative to commercial software.

  That's what Linux, open source software, and Ubuntu are all about. Linux (and Ubuntu Linux, which combines the various aspects and components of the Linux world together in its own, unique way) provides a great alternative to huge, monolithic operating systems.

  Open source software is copyrighted like proprietary software. However, open source software is licensed in a way that permits you to freely use, modify, and distribute the software as long as you don't prevent anyone else from doing the same. Open source software can be sold or given away.

• Have a computer.

  Unfortunately, Ubuntu Linux doesn't run on an abacus, TV, or coffee maker. However, it runs on most home computers, including PCs and Macintoshes.

  The Ubuntu Linux For Dummies CD-ROM runs on 32-bit PCs (most PCs made in the last 20 years). If you have a hot new 64-bit PC or a PowerPC-based Mac, you can download Ubuntu and use this book to run it.

You might not want to read Ubuntu Linux For Dummies if you're looking for the following:

• A book about wine tasting.

  In that case, read Wine Tasting For Dummies or rent the movie Sideways.

• Ubuntu Linux reference material.

  This book concentrates on the more basic aspects of the system and doesn't delve into the more complex.

• Information on building an Ubuntu Linux server.

  Ubuntu Linux comes in two flavors: Desktop and Server. Rather than trying to become the jack-of-all-trades — but an ace of none — Ubuntu decided to dedicate separate editions to the Linux desktop and Linux server. This book uses the Desktop version of Ubuntu Linux — surprise, surprise — and concentrates on helping you use it.

• Details on becoming a professional system administrator.

  Being a system administrator myself, I would love to write more about the job. I could fill books about it — actually, I have. System administrators are suave, sophisticated, talented, extremely well-paid professionals who are always good looking and have good people skills. Or is that the other way around? I always forget. Anyway, as wonderful as the profession is, there isn't enough room to do it justice here. So this book provides just enough system administration material to efficiently run your Ubuntu Linux computer.
