Lessons in Linux

Hello

The lessons contained in this series are designed to introduce Linux to an audience of new users. They will concentrate on what make Linux different than Windows or the Mac.

Linux is more that just an Operating System, it is a tool box. One of it's strengths is that it gives you the user everything you need to create new programs, or just customize what you have, to your likes.

Linux has flourished because it allowed programmers, or literally anyone who is willing to write computer code, to create and use computer programs which are under their control. At their day jobs, many programmers are hobbled in trying to build elegant programs by marketing pressures. The phrase It's good enough, ship it. does not resonate with people who like to take pride in what they build. Much like the painter who is never satisfied with his/her work, these are people who enjoy creating and working on elegant software programs.

Have you ever used a computer program that just doesn't work the way you want it to? Do you wish you could open up the covers and fix the problem? Well Linux allows you to do that by giving you both the source code to the programs, and the tools to rebuild them.

Have you ever wished that you could teach the computer a new trick? Well, in Linux you can. Because it gives you all the tools you need.

Another strength of Linux is that it encourages you to share you ideas, and your source code. The process of looking over another's work is one of the foundation principles in Science. Each researcher publishes his/her findings and methods. Before their work is accepted as fact, others look over their work and review the findings. Only after other researchers have reproduced the results and understood the findings is the principle accepted. This protects science from people making false claims.

Linux Revealed

This section will be a series of topics discussing different aspects of Linux and how to make use of them. This is not in any specific order or theme. You can jump in anywhere, so read through all the topics before starting. Select what is of interest to you and enjoy.

Here are a few suggestions on where to start.

• If you have never heard about Linux before you might want to try Why not Choose Linux to get an idea about why someone would choose Linux. If you want to learn more about the creator of Linux you might check your local library for the movie Revolution OS .
• 
  
• If you are interested in exploring the power of Linux, but are not ready to install a new Operating System, you might have a look at Cygwin for a Linux like environment under Windows. You can then follow the Lessons to get a taste of the power of the Command line in Linux.
• 
  
• If you are thinking about how to transition from Windows to Linux, have a look at How to Transition from Windows to Linux . Or if you are considering what distribution to install, try What to consider when picking a Linux distribution
• 
  
• You finally took the plunge and installed Linux on a computer. Now what? You could consider creating a network in your home by reading Home Network . Or if you are looking for help with a problem consider How to find HELP or even Documentation Galore . Of course you could consult the References below for some of the best documentation I have found available on-line.

If you are already a Linux user, I have several articles on what you can do with Linux. As a tinkerer myself, I keep finding new things to do with Linux. But the thing I like to stress the most about Linux is roll up your sleeves explore.

If you are interested in Computers, think of Linux as a well spring of knowledge. You can dive in and NEVER hit bottom.

• Compile Your own Application from Source This talk is about how to add applications to your distribution of Linux which were NOT part of the original package.
• 
  
• Emacs, the Swiss army knife of Linux This is a discussion about one application and how it can be used to perform a multitude of tasks in Linux.
• 
  
• Desktop Publishing, Linux style The Linux system supports a number of tools to allow you to publish your own work professionally or just for fun. This is an overview of the types of word processing and publishing tools available as well as a comparison of their strengths and weaknesses.
• 
  
• Documentation Galore Windows provides a help system for the user, but Linux provides man pages, info help, release notes, and Howtos in addition to help. How can you use all these different sources of information? You can even convert one into another.
• 
  
• How to find HELP One of the real strengths of Linux is the help available. This goes beyond documentation to enable users to help one another. The Linux community contains a wealth of information, advice, and even lessons to rival the best universities. Where is this information, and how can I learn from it.

  In addition to the topic of Finding Help, I will answer some questions about backups and how to Virus check and recover files from a Windows computer.

• 
  
• How to Transition from Windows to Linux So you are tired of fighting Viruses, Adware, Sypware, and programs which think they know how to use a computer better than you do. Have you heard about Linux in the News and wondering what is this new beast? Well here is your chance to make a change. Follow along as we discuss a strategy for converting your Desktop from Windows to Linux.
• 
  
• Install Decisions / Postscript and Printers Today we will discuss some more options involved in a Linux install. First the difference between Linux Servers and Workstations and then Package selection both during install and later. Following this information on installs and packages we will explore Postscript, and it's relationship to printers.
• 
  
• Linux and Home Automation This talk will focus on how to use Linux for Automation around your home. We will focus mostly on how to use the computer to take care of some routine tasks. Some of the automation will be focused on providing information to the home owners. Other parts will look at some ways of using the computer to make the home more information friendly.
• 
  
• What to consider when picking a Linux distribution In this talk we will discuss how to distinguish the different Linux distributions. Even though it seems like a beauty contest between distributions, there are some real differences. When you decide to install Linux on your computer, it is best to pick a distribution which suits your needs. We will discuss several differences in an attempt at differentiating them.
• 
  
• Why not Choose Linux Today we will talk about why Linux is not the first choice of many computer users. We will explore the reasons commercial software is often chosen over open source software. This is not an attack upon any particular brand or type of software, but an exploration of what appears to drive the choices.
• 
  
• Customize Linux OK you just finished installing Linux on your computer, so now you are done. Not really, now it is time to consider how you can tune the system to make it fit your needs and wants. We will discuss how to go about customizing your system.
• 
  
• What's inside your Computer We are going to discuss what hardware is inside your computer. We will be explaining what it is and how it words at a layman's level.

I will try to be clear on what techniques are for use behind a firewall and which can be used over the Internet.
• 
  
• Beginner's Linux Intro People often believe that Linux is only for advanced computer users. I will attempt to disprove this assumption tonight. Lets take a few minutes to have a look at what runs a Personal Computer, then Linux as a new user sees it.
• 
  
• Beginner's Linux Applications Most users don't see the operating system, only applications. So for our second session, lets compare application on Windows and Linux.
• 
  
• Let the Penguin help you What do you do when your computer won't boot? How do you remove a file which keep reappearing? How do you recover files when your operating system has crashed?
• 
  
• Linux Backup for Windows When it comes to backup, most of us don't do enough. But suppose it was as easy as running a script? Would you do it more often? Lets look at how a dual boot computer can use Linux to backup windows.
• 
  
• Dual Boot a new Computer Many new computers come with windows installed on the whole disk drive. How can you take this and convert it into a dual booting machine with Windows and Ubuntu?

Questions and Answers

Since this is a user group, sometime the meetings will be defined by the questions asked by the group. Since there is no global heading for this type of question and answer sessions, I thought I would give it it's own section. I will list the question and answer sessions by Date so they are easier to find.
